Description

  TECHNICAL FIELD The present invention relates to an incombustible material selective separation apparatus for further selecting an incombustible material fraction obtained by passing a crushed garbage through a primary sieve.

  The oversized waste transported to the oversized waste treatment facility is crushed by a crusher to become a crushed garbage. This waste crushed material is, for example, a combustible / non-combustible material sorter that separates combustible materials and non-combustible materials, a magnetic separator that attracts and sorts magnetic materials such as iron, and non-magnetic metals such as aluminum by electromagnetic induction. It is passed through an eddy current sorter that flies far away by repulsive force and is sorted into a combustible fraction, a non-combustible fraction, a magnetic fraction, and an aluminum fraction.

  As the combustible / incombustible material separator, a sieve sorter that separates the sieving material into the sieving material and the sieving material based on the size of the crushed material can be used. Various structures are known for the sieve sorter. For example, the following patent documents 1 to 3 can be referred to.

  For example, combustible materials such as papers, fibers, trees, and cocoons are less likely to become pulverized products having a small particle size even if they are crushed by a crusher, and are difficult to pass through the sieve of a sieve sorter. It is abundant in sieved products. Therefore, the magnetic material fraction and the aluminum fraction are further selected from the sieved product, and the remainder is used as the combustible material fraction. The combustible fraction is transported to the incineration site where it is incinerated.

  On the other hand, non-combustible materials such as glass and ceramics are easily contained in sieving materials because they are easily pulverized with a small particle size by a crusher and easily pass through the screen of a sieve sorter. Therefore, the magnetic material fraction is further selected from the under sieve, and the remainder is used as the incombustible material fraction. The incombustible fraction is transported to the final disposal site where it is landfilled.

  In addition, the magnetic material fraction and the aluminum fraction are reused as resources.

  However, in recent years, there has been a change in the composition of bulky waste that is brought into bulky waste treatment facilities. For example, the amount of waste plastic is increasing. Waste plastic is a combustible material, but it tends to be a pulverized product having a small particle size in the destruction treatment, and therefore, it is selected as a non-combustible material fraction together with a pulverized product of glass or ceramics. For these reasons, the amount of incombustible fraction discharged from bulky waste disposal facilities is increasing year by year. However, the Ministry of the Environment estimates that the disposal capacity of existing final disposal sites is limited, and the remaining years of final disposal sites in the Tokyo metropolitan area are four years. It is necessary to extend the life of the existing final disposal site, which is under pressure, and there is a strong need to reduce the incombustible fraction.

  As a method of reducing the incombustible fraction, for example, a method of reducing the amount of the under-sieving material by making the sieve screen finer is conceivable. However, if the screen is simply made finer, the sorting ability is lowered and the risk of clogging is increased, which is not preferable. Rather than that, the selective sorting, in which the incombustible fraction is first sorted with a coarse sieve and then secondarily sorted with a fine sieve, is superior. However, it is difficult to procure funds with the proposal to construct a new waste disposal facility that can be selectively sorted, and it is difficult to secure an additional space for the secondary sieve with the proposal to remodel the existing equipment. I came.

  Therefore, the object of the present invention is to provide an incombustible material selection and separation device that can be adapted to existing bulky waste treatment facilities, does not require new equipment installation space, and can reduce equipment costs, and solves the above problems. There is to do.

  In order to achieve the above-mentioned object, the non-combustible material sorting device of the present invention includes a hopper for injecting a non-combustible material fraction obtained by primary sorting of crushed garbage, and a secondary sorting inclined in the hopper. A sieve sorting machine, a partition plate arranged below the sieve sorting machine and dividing the inside of the hopper into an incombustible material accommodating space and a combustible material accommodating space, and an openable and closable located below the incombustible material accommodating space An incombustible discharge port, an openable / closable combustible discharge port disposed below the combustible containing space, and a vibration device provided in the sieve sorter, wherein the sieve sorter has an upper end Is disposed on the incombustible material accommodating space, the lower end portion is disposed on the combustible material accommodating space, and the incombustible material that has passed through the sieve sorter is stored in the incombustible material accommodating space, Combustible material that has not passed through the separate machine is stored in the combustible material storage space. Characterized in that it is configured to.

  According to the present invention, a secondary sorting screen is disposed in the hopper at an angle, and a non-combustible fraction obtained by primary sorting of crushed waste is introduced and passed through the screening screen. Is stored in the incombustible material storage space and taken out from the incombustible material discharge port, and the material that has not passed through the sieve sorter is stored in the combustible material storage space and taken out from the combustible material discharge port to further select the incombustible material fraction. Thus, the amount of incombustible waste to be disposed of can be reduced. In addition, it is possible to provide a function for further selecting non-combustible materials from conventional non-combustible material fractions simply by providing a sieve sorter and a partition plate in the hopper for introducing the non-combustible material fraction provided in the existing equipment. Therefore, no installation space for a new device is required, and the equipment cost can be reduced.

  In the incombustible material selective sorting apparatus of the present invention, the sieve sorter is supported so that the inclination angle thereof can be changed, and the lower end of the partition plate is formed between the incombustible material discharge port and the combustible material discharge port. It is preferable to have a structure that can be expanded and contracted in the height direction so that the upper end thereof is supported between and supported by the lower surface of the sieve sorter. According to this, by changing the inclination angle of the sieve sorter, the moving speed of the incombustible fraction that moves the sieve downward in the inclination direction is changed by the vibration of the vibration device, and the incombustible and the sieve passing through the sieve are changed. The ratio of combustibles that do not pass through can be adjusted, and the amount of incombustibles that are subjected to landfill processing can be adjusted.

  In the incombustible material selective sorting apparatus of the present invention, it is preferable that the vibration device includes a vibration motor directly attached to the lower surface of the sieve sorting machine. According to this, the vibration of the vibration motor directly attached to the lower surface of the sieve effectively vibrates the sieve using the deflection of the sieve, making it easy for incombustibles to pass through and suppressing clogging. it can.

  In the incombustible material selective sorting apparatus of the present invention, the sieve sorting machine is configured by stacking a plurality of sieves having different sieve sizes with a cushioning material interposed therebetween, and the sieve size gradually increases toward the lower stage. Is smaller, and those passing through all of the plurality of sieves are stored in the incombustible material storage space, and those that do not pass through any of the plurality of sieves are stored in the combustible material storage space. It is preferable that it is comprised. According to this, the waste contained in the incombustible fraction is supplied to the fine sieve through a coarse sieve to finally obtain the incombustible having the desired particle size, thereby increasing the passage rate of the incombustible. , Clogging can be suppressed.

  The hopper mounting part according to the present invention is a part that is attached to a hopper for introducing a non-combustible material fraction obtained by primary sorting of waste crushed material, and is a screen for secondary sorting that is disposed in an inclined manner in the hopper. It is provided with another machine and the partition plate which is arrange | positioned under the said sieve sorter and divides the inside of the said hopper into an incombustible material accommodation space and a combustible material accommodation space.

  According to the present invention, a secondary sorting screen is disposed in the hopper at an angle, and a non-combustible fraction obtained by primary sorting of crushed waste is introduced and passed through the screening screen. Is stored in the incombustible material storage space and taken out from the incombustible material discharge port, and the material that has not passed through the sieve sorter is stored in the combustible material storage space and taken out from the combustible material discharge port to further select the incombustible material fraction. Thus, the amount of incombustible waste to be disposed of can be reduced. In addition, it is possible to provide a function for further selecting non-combustible materials from conventional non-combustible material fractions simply by providing a sieve sorter and a partition plate in the hopper for introducing the non-combustible material fraction provided in the existing equipment. Therefore, no installation space for a new device is required, and the equipment cost can be reduced.

It is a decomposition | disassembly side view of the same sieve sorter. It is a disassembled perspective view of the same sieve sorter.

  Hereinafter, the incombustible material selective sorting apparatus of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic view showing an embodiment of the incombustible material selective sorting apparatus 100. The non-combustible material sorting device 100 includes an outer wall 1 that forms a hopper, an inlet 2 that inputs a non-combustible material fraction that has been primarily selected in a previous process, and an inner wall 1 that is disposed inside the outer wall 1 based on the non-combustible material fraction based on particle size. And a sieve sorting machine 20 that separates into non-combustible material (under-sieving material) and combustible material (up-sieving material), and the space surrounded by the outer wall 1 is disposed below the sieve sorting machine 20 and the non-combustible material containing space 4a. The partition plate 3 divided into the combustible material accommodating space 4b, the door 5a of the incombustible material discharge port that can be opened and closed disposed below the incombustible material accommodating space 4a, and the combustible material that can be opened and closed disposed below the combustible material accommodating space 4b. The door 5b of a thing discharge port and the vibration apparatus 30 provided in the sieve sorter 20 are provided.

  The outer wall 1 is a hopper-shaped structure (for example, a funnel shape whose diameter is reduced downward) having a receiving portion inside the outer wall 1, and is an inlet 2 adapted to a discharge port of an existing primary sorting machine (not shown). Incombustible discharge port door 5a (door closed state), combustible discharge port door 5b (door closed state).

  In the figure, the state where the incombustible discharge port door 5a is rotated and opened is represented by a two-dot chain line denoted by reference numeral 5aa, and the state where the combustible discharge port door 5b is rotated and opened is It is represented by a two-dot chain line denoted by reference numeral 5bb. However, the open / close doors of the discharge doors 5a and 5b shown in the figure are merely examples, and are not limited to the rotary open / close doors, and other types of doors may be employed.

  The sieve sorter 20 is supported by the fixed support portion 6 and the movable support portion 8 disposed at a position lower than the fixed support portion 6 via the leg portions 28 a and 28 b protruding from the lower surface of the sieve sorter 20. It is inclined and arranged inside the outer wall 1.

  For example, the leg portion 28a and the fixed support portion 6 are rotatably connected by a rotating shaft 6a inserted through the leg portion through-hole 29a, and the bearing portion 6b that supports the rotating shaft 6a is provided with a vibration isolating member 6c. Via the fixed beam 7 fixed to the outer wall 1 of the hopper.

  On the other hand, the leg portion 28b and the movable support portion 8 are rotatably connected by, for example, a rotating shaft 8a inserted through the leg portion through-hole 29b, and the bearing portion 8b that supports the rotating shaft 8a is a vibration-proof member. It is mounted on a movable beam 9 that can move vertically and horizontally with respect to the hopper outer wall 1 via 8c.

  The sieve sorter 20 straddles the partition plate 3, and the higher end of the sieve sorter 20 is located above the incombustible material accommodation space 4a and the lower end is located above the combustible material accommodation space 4b. The object is arranged so as to surely fall into the combustible material accommodating space 4b, and the movable beam 9 is moved, whereby the rotating shaft 6a is rotated as a fulcrum, and the inclination angle of the sieve sorter 20 can be changed.

  The range of the inclination angle of the sieve sorter 20 is not particularly limited, but a range of 25 ° to 35 ° is preferable. As the inclination angle is smaller, the sorting ability is improved. However, if the inclination angle is smaller than 25 °, the time for staying on the sieve surface becomes too long, and the amount of waste treatment decreases. As a countermeasure, it is possible to greatly vibrate the sieve to increase the amount of processing, but there is a problem that the power cost increases due to the large vibration. On the other hand, if the inclination angle is larger than 35 °, the sorting ability is lowered, and the incombustible material cannot be recovered, which is not preferable.

  The vibration device 30 is directly attached to the lower surface of the sieve of the sieve sorter 20, and can effectively vibrate the sieve using the deflection of the sieve. The vibration of the sieve sorter 20 is weakened by the vibration isolating member 6c of the fixed support portion 6 and the vibration isolating member 8c of the movable support portion 8, so that the vibration is not transmitted to the outer wall 1 as much as possible (so as not to generate a large noise). It has become. In FIG. 1, the vibration device 30 is attached near the fixed support portion 6, but is not particularly limited, and may be near the center of the sieve sorter 20 or the movable support portion 8.

  The sieve sorter 20 including the vibration device 30 configured as described above changes the inclination angle of the sieve sorter 20 and the vibration waveform of the vibration device 30 so that the screen of the sieve sorter 20 is downward in the inclination direction. By changing the moving speed of the moving incombustible fraction, the ratio of the incombustible material passing through the sieve and the combustible material not passing through the sieve can be adjusted.

  The partition plate 3 follows the lower surface of the sieve sorter 20 and has a structure that can expand and contract in the height direction. For example, the partition plate 3 includes a lower member 3a of the partition plate and an upper member 3b of the partition plate that is slidable with respect to the lower member 3a. It can be expanded and contracted in the vertical direction. Moreover, the lower end of the lower member 3a is rotatably supported by a rotating shaft 3c disposed between the door 5a of the incombustible discharge port and the door 5b of the combustible discharge port. According to this, even if the inclination angle of the sieve sorter 20 is changed, it is possible to follow the upper end of the partition plate 3 so as not to be separated from the lower surface of the sieve sorter 20. Can be divided into an incombustible material accommodating space 4a and a combustible material accommodating space 4b, and can be reliably partitioned so that the incombustible material and the combustible material do not mix.

  Next, the sieve sorter 20 will be described in detail with reference to the drawings.

  3 and 4 show a side view and a perspective view of the sieve sorter 20, respectively. The sieve sorter 20 includes a sieve sorter body 21 having sieves 24a and 24b, and leg portions 28a and 28b protruding from the lower surface of the sieve sorter body 21, and a vibration device 30 is provided on the lower surface of the sieve sorter body 21. Is installed directly. In the non-combustible material sorting apparatus 100, the sieve sorting machine 20 is mounted so that the leg portion 28a is higher than the leg portion 28b, so that the non-combustible material fraction moves in the direction of the arrow shown in the drawing, Is done.

  Hereinafter, it will be described in more detail with reference to an exploded side view of the sieve sorter 20 shown in FIG. 5 and an exploded perspective view shown in FIG.

  The main body 21 of the sieve sorter has a buffer material 23a, a screen 24a, a buffer material 23b, a screen 24b, a buffer material 23c, and a presser plate 25 stacked in this order on the upper surface of the frame 22, and these members are perforated. A bolt 26a is inserted into the bolt insertion hole 27 and is configured as a part having two sieves fastened by a nut 26b screwed into the bolt 26a. In the present embodiment, the sieve sorter 20 in which two sieves are stacked is illustrated, but the number of sieves is not particularly limited. For example, the sieve is simplified to one sheet, or two or more sheets are stacked. The sorting ability may be increased. However, in the case of stacking a plurality of sheets, stacking is performed so that the size of the sieve meshes gradually decreases as it goes to the lower stage, and those passing through all of the plurality of sieves are stored in the incombustible material accommodation space 4a, What does not pass through any of the sieves is configured to be stored in the combustible material accommodation space 4b.

  The frame 22 is a structure assembled with, for example, a steel frame so as to withstand a bending load, and has a bolt insertion hole 27 for inserting a bolt 26a in the longitudinal direction of the upper surface.

  As the sieves 24a and 24b, for example, a thin plate (punched metal) having a large number of circular holes as a sieve mesh, a wire mesh, or the like can be used. As an example of the size of the sieve mesh, when the mesh size of the primary sorter (not shown) is 15 to 20 mm, the mesh size of the sieve 24b arranged in the upper stage of the sieve sorter 20 is 6 mm and arranged in the lower stage. A suitable mesh size of the sieve 24a is 5 mm. However, since the properties of the incombustible fraction to be introduced are various, the size of the sieve mesh is not limited to the above numerical values and can be appropriately changed.

  The cushioning materials 23a, 23b, and 23c are elastic, for example, rectangular plates made of a rubber material, and are arranged vertically along two sides extending in the longitudinal direction of the sieves 24a and 24b. It is fastened by a nut 26b and presses and fixes the peripheral portions of the sieves 24a and 24b. For this reason, even if the central portions of the sieves 24a and 24b vibrate violently by the vibration device 30, the buffer members 23a, 23b and 23c absorb vibration energy in the peripheral portions, and loosening and fatigue failure of the fastening portions fixing the sieves. Is preventing.

  The vibration device 30 includes a vibration motor 31, a mounting plate 32 disposed in contact with the lower surface of the sieve 24a, a motor cushioning material 33 disposed in contact with the upper surface of the sieve 24b, and a motor cushioning material. 33 between the motor fixing plate 34 disposed on the upper surface of 33, the bolt 35a inserted into the bolt insertion hole 36 formed in these members, the nut 35b screwed into the bolt 35a, and the upper surface of the frame 22. And a vibration isolating member 37 inserted into the screen, and is suspended directly on the sieves 24a and 24b. According to this, the vibration of the vibration motor directly attached to the lower surface of the sieve 24a is used to effectively vibrate the sieve using the deflection of the sieve, making it easy for incombustibles to pass through and suppressing clogging. Can do.

  As the vibration motor 31, a vibration motor or the like in which a fan-shaped weight is eccentrically attached to the rotation shaft of the motor and vibration is generated by centrifugal force when the rotation shaft rotates can be used.

  A method for selectively sorting the incombustible material fraction that has been primarily sorted using the incombustible material selective sorting device 100 described above will be described.

  The bulky trash brought into the bulky trash disposal facility is first crushed by a crusher to become a crushed garbage. Garbage waste is separated into a combustible fraction, a non-combustible fraction, a magnetic fraction, and an aluminum fraction by a primary sorter of existing equipment. Among these, the primary-sorted incombustible fraction is introduced from the inlet 2 of the non-combustible material sorting apparatus 100, and the high position (the end where the leg portion 28a is disposed) of the inclined screen sorter 20 is disposed. Let fall. If it drops to a high position, the time for staying on the sieve becomes long, so that it can be sorted efficiently. For example, a guide plate (not shown) may be installed under the insertion port 2 in order to control the drop position.

  The sieve sorter 20 is vibrated using the deflection by the vibration device 30 directly attached to the lower surface. The vibration motor 31 of the vibration device 30 may be continuously vibrated or may be intermittently vibrated. It is preferable to vibrate intermittently because the residence time on the mesh can be adjusted, and the effect of preventing clogging can be obtained by the change of the vibration pattern due to the eccentric behavior when the vibration motor is started and stopped.

  The incombustible fraction that has obtained the vibration energy moves toward a low position (the end where the leg portion 28b is disposed) while jumping on the sieve surface, and is secondarily selected during that time.

  Among the incombustible matter fraction, the incombustible material having a small particle size passes through the mesh of the sieve 24b arranged in the upper stage of the sieve sorting machine 20 and is sorted as an under-sieved material, and further the sieve of the sieve 24a arranged in the lower stage. It passes through the eyes and is carefully selected as an under-siege, and is accommodated in the incombustible material accommodating space 4a. The combustible having a large particle size cannot pass through the sieve 24b arranged on the upper stage of the sieve sorter 20, and is contained in the combustible containing space 4b as the sieve on the sieve 24b. Note that the sieve top of the sieve 24a that passes through the sieve 24b but cannot pass through the sieve 24a is also accommodated in the combustible material accommodation space 4b.

  The incombustible material stored in the incombustible material accommodation space 4a is taken out by opening the door 5a of the incombustible material discharge port, carried to the final disposal site, and subjected to landfill processing. On the other hand, the combustible material stored in the combustible material accommodation space 4b is taken out by opening the door 5b of the incombustible material discharge port, and is taken to the incineration site and incinerated.

  When the contents of coarse trash change and the properties (particle size distribution, etc.) of the incombustible fraction obtained from the crushed coarse trash are changed, the inclination angle of the sieve sorter 20 and the vibration device 30 are adjusted according to the change. By changing the vibration waveform (amplitude, period, continuous mode or intermittent mode), the fraction of non-combustible and combustible materials can be adjusted.

  As described above, the primary-sorted incombustible fraction is secondarily sorted by the non-combustible material selective separation apparatus 100 of the present invention, thereby reducing the amount of combustible material mixed into the incombustible material and reducing the incombustible material. The burden on the final disposal site can be reduced.

  In addition, in order to simplify the apparatus structure, the non-combustible material selection / separation apparatus 100 may be a selection / separation apparatus in which a driving device for driving the movable beam 9 is not provided and the inclination angle of the sieve sorter is fixed. As a result, the equipment cost can be reduced.

  Next, with reference to FIG. 2, another embodiment of the incombustible material selective sorting apparatus according to the present invention will be described. In the incombustible material selective sorting apparatus 200 shown in FIG. 2, the lower end of the lower member 13a of the partition plate 13 is rotatably connected to the wall portion 1 by a rotating shaft 13c. On the other hand, the upper end of the upper member 13b slidable with respect to the lower member 13a of the partition plate is rotatably connected to the leg portion 28c of the sieve sorting machine 20a by a rotating shaft 13d. When the inclination angle of the sieve sorter 20a is changed, the partition plate 13 rotates and expands and contracts in conjunction with the sieve sorter 20a. In this way, it is not necessary to provide a dedicated drive device for extending and contracting the partition plate 13, and the device structure can be simplified.

  The above has described the overall configuration of the incombustible material selective sorting apparatus. However, the essential parts of the present invention are the sieve sorting machine 20 and the partition plate 3 for secondary sorting, and are not limited to the above embodiment. For example, the incombustible material fraction separating apparatus of the present invention can be configured by using the hopper outer wall of the incombustible material fraction provided in the existing equipment as it is and attaching the sieve sorter 20 and the partition plate 3 as hopper mounting parts. it can. Accordingly, it is possible to further reduce the amount of incombustible waste to be landfilled by further selecting incombustible materials while reducing the equipment cost.
