Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for compressing garbage, and more specifically, when garbage is discharged from a kitchen into a garbage sink of a sink, the garbage is automatically compressed and filled into a container. The present invention relates to a garbage compression device.

[0002]

2. Description of the Related Art Even if there is no resistance to directly touching pre-cooked foods such as vegetables, meats and fish, and cooked foods with them, when these become raw garbage, most people treat them as dirty. You will feel resistance to touch. Therefore, as a device for treating raw garbage without touching it with the hands, a device for treating raw garbage such as a disposer has been developed, but the result is sufficiently satisfactory in terms of usability and environmental measures. It is well known that it has not yet spread.

By the way, garbage is generally bulky, and its volume can be reduced to a fraction when compressed.
And the adhered water flows to the drainage side during the compression process, but unless the garbage is cut into small pieces, the BOD is not much different from the case where it is not compressed, and the moisture does not exude even if the compressed garbage is left alone. In addition, the present inventors confirmed that by performing the above treatment while introducing ozone, a bad odor could not be generated even if it was left for a few weeks in a hot season, and it was confirmed that it could be incorporated in a sink in a home. We are developing a raw garbage compression processing device.

[0004]

By the way, the function required for the garbage compressing apparatus for treating the garbage generated at home is that the fish ruffs that are usually produced in home cooking, cut livestock bones, clam shells, etc. It is a device that does not block the narrow part of the device with relatively small hard solid matter or elastic fiber vegetables such as Chinese cabbage, and that does not increase the BOD value in the wastewater by compressing the garbage. Is required.

The present invention has been made by paying attention to the above problems. Mainly, raw garbage produced by households is dehydrated / compressed without touching it to reduce its volume, and the raw garbage is dried as raw garbage. It is an object of the present invention to provide an apparatus for compressing food waste that can be automatically sent into a container.

[0006]

In order to achieve the above object, the structure of the garbage compressing apparatus of the present invention is such that a garbage compressing section consisting of a screw type compressor arranged in the lateral direction is formed,
A raw garbage inlet passage is arranged vertically with the upper side of the compression section opened, a raw garbage cutting portion is arranged in the inlet passage, and a pump portion is arranged on the outlet side of the compressed raw garbage to cut the raw garbage. The portion is formed by a plurality of fixed blades and a rotary blade that rotates in a direction intersecting with the fixed blades, and the pump portion is provided with a rotor coaxially with a rotating shaft of the compression portion, and a lower wall of the compression portion. And a plurality of drain holes are provided in the pump chamber wall, and a garbage outlet passage is attached to the pump portion, and the outlet passage is arranged so that water flowing into the device passes through a height at which the water does not flow out from the outlet passage. Along with this, a throttle part is provided on the way.

There is no particular limitation on the arrangement of the fixed blades of the cutting portion, and the fixed blades may be arranged in either the vertical direction or the horizontal direction.
In addition to the blade that rotates in the direction intersecting with the fixed blade, a blade that rotates in the direction parallel to the fixed blade may be provided. The point is that it is enough to cut the garbage with the rotary blade and at the same time push the garbage with the rotary blade and push it between the fixed blade and cut it into a size that can be transported and compressed by the screw compressor. Incidentally, the cutting, even if the gap between the rotary blade and the screw is narrowed cutting occurs between the rotary blade and the screw, also, changing the ratio of the rotational speed of the rotary blade and the screw changes the cutting efficiency Can be made. Generally, the rotation of the rotary blade is made larger than the rotation speed of the screw.

The pump section is not limited to a pump type as long as it can transport compressed raw garbage into the raw garbage container through the outlet passage. For example, the rotor has a paddle shape, and the garbage outlet is opened at the part where the paddle approaches the peripheral wall of the pump chamber. The pump chamber wall is gradually expanded to form a large gap between the paddle and the paddle. However, the opening may be provided at the portion where the gap is the largest.

Further, as the pump portion, a partition wall is provided at a part between the pump portion and the compression portion, and a vane which can be retracted from the pump chamber peripheral wall is provided between the pump chamber peripheral wall and the rotor, and the vane is directed toward the rotor. The urine is elastically urged, and is guided by the peripheral surface of the rotor, appears and disappears in the pump chamber, and collects the raw dust trapped between the throttle portion of the raw dust outlet passage, the rotor, the pump chamber peripheral wall, and the partition wall of the rotor. It may be formed so as to pressurize intermittently by rotation. It should be noted that the vane may be provided with a gap between the vane and the rotor in a non-pressurized state to further reduce wear and friction noise.

There is no particular limitation on the position where the drain hole is provided. The pore size is also not particularly limited, but if it is usually about 1 mm or less, particularly 0.5 mm or less, clogging is likely to occur, and if it is about 2 mm or more, the ratio of fine garbage mixed in the waste water is large, which is not preferable. . In addition, in order to further shorten the length of the drain hole, the outside may be widened.
Further, as a means for arranging the outlet passage at a high position,
The outlet passage may be attached at a high position in the pump chamber, or the outlet passage may be inclined to reach a predetermined height.

[0011]

The above-mentioned means of using a screw compressor to compress the raw garbage can continuously compress the raw garbage and make the draining condition more constant. In addition, the means for arranging the cutting part in front of the compression part transports large garbage and bulky and elastic fibrous garbage such as Chinese cabbage with a screw compressor.
In addition to being compressible, the destruction of cells of raw garbage can be suppressed as much as possible, and the raw garbage compressed / pressurized without generating high BOD water can be moved inside the apparatus, particularly in the passage.

[0012] The rotary blade and the fixed blade while the food waste compressing device is stopped holds the food waste introduced into the food waste inlet passage so as to float in the air, and water attached to the food waste,
You can let the water drain to wash food and dishes. When the compression treatment is performed after draining in this way, it is possible to further reduce the water content in the raw garbage after compression. Therefore, if the food waste that has been produced during cooking is drained during a meal, and the food waste that has a low water content after the meal, such as leftover food, is compressed and then the dishes are washed after the meal, The increase in BOD can be suppressed as low as possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The garbage compacting apparatus of the present invention will be described in detail below with reference to the accompanying drawings with reference to the accompanying drawings. The raw garbage compressing apparatus (hereinafter simply referred to as apparatus) 1 of the present embodiment is provided with a raw garbage inlet passage 3 above a compressing section 2 which is a laterally arranged screw compressor as shown in FIG. Is provided with a cutting section 4 for the garbage, and on the garbage exit side of the compression unit 2,
The pump unit 5 is attached. Hereinafter, the garbage will be sequentially described according to the processing order. Although not shown specifically, the compression operation of the apparatus 1 was performed by introducing ozone.

In FIG. 2, a rubber chrysanthemum plate (not shown) is formed in the bottom plate of a sink 6 of a sink (not shown) so that the entrance passage 3 is opened so that raw garbage in the hole cannot be seen. No)
I am trying to attach. Then, the cutting portion 4 is arranged below the inlet passage 3. As shown in FIGS. 1 and 2, the cutting portion 4 includes a plurality of fixed blades 4a attached to face the wall surface of the inlet passage 3 and a rotary blade 4d attached to the tip of an arm 4c fixed to the rotating shaft 4b. Composed by In this embodiment, the rotary blade 4d is arranged parallel to the rotary shaft 4b,
You may attach so that it may face diagonally.

Since the cutting portion 4 is formed as described above, when the apparatus 1 is stopped, the garbage entering the inlet passage 3 is
Except for fine ones, the blades 4a and 4d block the falling and hold the blades floating in the air. Therefore, if left in this state, draining can be performed. Further, a blade may be provided on the front surface of the arm 4c in the rotation direction. In addition, the rotary blade 4 with the rotation axis in the vertical direction above and below the fixed blade 4a.
Garbage can be cut even if d is attached.

The compression unit 2 is a drum 2b integrally attached to a rotary shaft 2a and a spiral feed blade 2c attached to the drum 2b. The reason for providing the drum 2b is to avoid the central portion which is a blind spot of the pump portion 5 described below, and the feed blade 2c may be directly attached to the rotary shaft 2a. The lower side wall 2d is provided with a large number of drainage holes 7a so that the adhering water that has exuded due to the compression flows down from the jacket 8a to the drain pipe 9a. In addition, the garbage collected in the water drainage hole 7a is not fed to the feed wing 2.
It can be removed when c contacts. Further, if the diameter of the drum 2b is increased, the width of the feed blade 2c becomes narrower, and the size of the cut garbage tends to be smaller.

A pump portion 5 is continuously provided on the extruding side of the compression portion 2, and a partition wall 5a is provided at a part of the boundary with the compression portion 2. Reference numeral A shown in FIGS.
The inner peripheral side edge of a is represented, and the portion B partitioned by the partition wall 5a is a portion that serves as a pressurizing portion. And 2 in FIG.
The rotor 5b shown by the dotted line corresponds to the position of the rotor 5b in FIG. 1, and the rotor 5b shown by the solid line shows the rotor position where compression is almost completed. Therefore, when the rotor 5b rotates from the state of the chain double-dashed line and reaches the position where it overlaps the peripheral edge A of the partition wall 5a, the garbage in the pressurizing section B is separated from the compressing section 2 by the rotor 5b, and the pressurizing section B is pressed. It is contained and pressurized. Reference numeral 8b shown in each drawing
Is a jacket, 8c is a casing of the jacket 8a, 8
d is the casing of the jacket 8b. Further, in FIG. 4, the outline of the partition wall 5a is shown by a chain double-dashed line to facilitate distinction from the rotor 5b.

The rotor 5b of this embodiment has a flat cylindrical shape and is eccentrically attached to the rotary shaft 2a. The peripheral surface portion farthest from the rotary shaft 2a is in contact with the cylindrical wall 5c (FIGS. 1 and 3), and the side surface is It is attached so as to contact the side wall 5d (FIG. 1). By the way, a large number of drain holes 7b are opened in the cylindrical wall 5c of the pressurizing portion B, and a large number of drain holes 7c are also opened in the side wall 5d so that water that has been extruded under pressure can be drained. Therefore, these drain holes 7b, 7c
A plate made of a soft metal such as phosphor bronze in the slit provided in the rotor 5b in order to remove the garbage accumulated in the rotor.
The rotor 10 is fitted in the rotor 5b so that the member 10 is in contact with the cylindrical wall 5c and the side wall 5d. That is, the plate 10 is the rotor 5b
The plate 10 is fixed by the screw 10b attached to the hole 10a formed in the hole, and the plate 10 is brought into contact with the cylindrical wall 5c and the side wall 5d. The water from the drainage hole 7b is discharged into the jacket 8a and flows into the drain pipe 9a.
The water from c is discharged into the jacket 8b and flows into the drain pipe 9b. In this embodiment, the drain pipe 9b is the drain pipe 9a.
It was piped so that it might join.

By the way, a portion of the end edge C of the partition wall 5a at the end of the rotor 5b in the rotation direction communicates with the pressing portion B and the opening D except when the plate 10 passes. Therefore, the garbage cannot be pressed unless a partition is provided in this portion. Therefore, in this embodiment, the rod 11a
The vane 11 is urged to the rotor 5b side by the spring 11b through the above, and the end portion C divides the pressurizing portion B from the opening portion D. In addition, at a position where the rotor 5b and the cylindrical wall 5c are wide open, a stopper is provided so that the vane 11 and the rotor 5b are separated from each other.
11c is attached to avoid unnecessary wear.
Further, the vane 11 is arranged to form an angle α with the axial direction of the rod 11a as shown in FIG. With this arrangement, when the rotor 5a pushes and retreats, the raw garbage is pressurized, and when the pressurization is completed, the pump portion 5 is pushed by the spring 11b without receiving the resistance of the stretched raw garbage.
You can enter inside. In this embodiment, the angle α is 10
It was °.

In this way, the raw dust contained in the pressurizing section B is pushed out to the outlet passage 12 side. Exit passage 12
As shown in FIG. 3, the garbage was once raised to a high position by a height h so that a large amount of water flowing down from the outlet passage 12 did not flow out. The compression force of the feed vane 2c does not act on the wall surface 2e side of the compression portion 2 on the bearing 13 side. Therefore, if a new jacket is provided between the wall surface 2e and the bearing 13 and a drainage hole is provided here, drainage can be easily performed and a means for preventing water from flowing to the outlet passage 12 side can be provided.

As shown in FIG. 5, the nozzle portion 14 attached to the outlet passage 12 is provided with a throttle portion 14a, and high pressure is generated in the pressurizing portion B so that adhered water and air trapped in the compressed raw garbage. Is discharged from the drainage holes 7b and 7c to further compress the volume. Further, a raw garbage container such as a bag (not shown) was attached to the tip of the nozzle portion 14 so that the compressed raw garbage was filled therein. And
Ozone is discharged from the ozone passage 15 into the nozzle portion 14 to sterilize the inside of the nozzle portion 14 and the garbage container.

Further, an opening / closing valve 14b is attached to the opening of the front end of the throttle portion 14a so that it can be opened / closed by a lever 14c.
It prevents the garbage from falling off when the garbage container is removed. Since the pressurized and compressed raw garbage has poor fluidity, there is no fear of dropping even if the on-off valve 14 cannot be closed completely. The bulging portion 14d shown in FIGS. 5 and 6 is provided to prevent the garbage container such as the bag attached to the nozzle portion 14 from slipping off. The lever 14c may be manually operated, or may be automatically rotated when the door of the sink is opened to replace the garbage container so that the on-off valve 14b is closed.

As a means for detecting the filling of raw garbage, for example, a container is placed on a spring type balance, and when a certain weight is reached, a micro switch is activated to give an alarm, or the tip of the lever of the micro switch is searched. Means such as attaching a needle and issuing an alarm when the garbage in the bag reaches a certain height can be used. In this case, if ozone is compressed in a state where it is introduced and filled in the garbage container, there is no possibility of producing a bad odor even if the container is left under the sink until the container is full.

When the feed vane 2c and the rotor 5b are driven by the rotary shaft 2a, the balance between compression and pressurization is determined by the feed vane 2
It can be adjusted by the pitch of c, the shape of the rotor 5b, and the like. Further, although both the feed blade 2c and the rotor 5b are driven by the rotating shaft 2a, they may be attached to different shafts. In addition, when washing or cooking with a sink, dishware such as chopsticks and other relatively small items may inadvertently flow out of the drainage port of the sink, and you may need to put your hand out of the drainage port to remove it. It is extremely dangerous to put your hand in a hurry when the garbage compressing device of the present invention is operating. Therefore, in this embodiment, the drain of the sink is provided with a lid so that the motor cannot be turned on unless the lid is closed. Further, a timer (not shown) was installed in the device 1 so that the compression operation was automatically performed after a certain draining time.

[0025]

As described above, since the raw garbage compressing apparatus of the present invention cuts the raw garbage with the rotary blade and the fixed blade before the compression processing of the raw garbage, the cell structure of the raw garbage is reduced. Can be compressed with a screw compressor without breaking more than necessary. Therefore, the BOD in the wastewater can be maintained at the same BOD in the wastewater as in the conventional case where the compression process is not performed. Moreover, the water adhering to the raw garbage can be removed as much as possible before compression, and the raw garbage can be compressed in a state where the water content is less, thereby reducing the volume of the raw garbage.
