Description

[Detailed description of the invention] (Field of industrial application) This invention can be used to collect waste paper, plastic sheets, cardboard, pieces of wood, pieces of cloth, solid materials such as plastic and rubber, stones, sand, metal scraps, glass scraps, etc. This invention relates to a device for efficiently sorting various types of waste before processing.

(Prior Art) A large amount of the above-mentioned waste is discharged from general households, offices, factories, and the like. Some of these wastes are reusable, and some emit toxic gases when incinerated, so many local governments carry out sorting and processing of these wastes at treatment plants.

(Problem that the invention aims to solve) However, the above sorting process requires a lot of manpower and effort, and some local governments provide administrative guidance to sort and dispose of waste at the waste disposal side, but it is not thorough enough. The reality is that there is a strong need for drastic improvements in waste treatment systems.

The present invention has been developed in view of the above, and it is an object of the present invention to provide a new waste sorting device that can easily sort out miscellaneous waste so that it can be efficiently disposed of.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object will be explained based on the attached embodiment diagrams. 1 is a plan view of the device of the present invention, FIG. 2 is a cross-sectional view taken along the line -- in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line -- in FIG. That is, the waste sorting device of the present invention has a large number of through holes 1 on the board surface.
1... is bored and the driving central shaft 12 is installed in an inclined state. A waste supply zone 2 formed closer to the direction side, a suction area 3 including the supply zone 2 and sucking toward the back side of the disk 1, and a suction area 3 provided adjacent to the suction area 3 with the radial line L in between. a discharge area 4 configured to discharge air from the back side to the front side of the disk 1; a lightweight waste discharge zone 5 formed on the lower side of the disk 1 along the inclination direction from the discharge area 4; The main feature is that a heavy waste discharge zone 7 is formed adjacent to the light waste discharge zone 5 at the lower part of the supply zone 2 in the inclined direction and sandwiching the weir plate 6 along the radius line L. It is something.

A brush 6 for removing clogging is attached to the weir plate 6.
It is desirable to add 1.

The waste that is targeted by the device of the present invention is the above-mentioned miscellaneous waste, but if it includes so-called bulky waste such as furniture, it is desirable to crush it in advance.

(Operation) The procedure for sorting waste with the sorting device having the above configuration will be described. The disk 1 is rotated in the direction of arrow R, and the suction in the suction area 3 and the discharge in the discharge area 4 are turned on, and waste is supplied to the supply zone 2. Among the supplied wastes, small ones such as sand and metal scraps fall to the lower part of the disk 1 through the through holes 11. Thin and light materials such as paper or plastic sheets are attracted to the through holes 11 and moved to the discharge area 4 as the disk 1 rotates. On the other hand, objects that are heavy, such as pieces of stone, metal, and glass, or relatively heavy, such as pieces of cloth, cardboard, and molded plastic, and that do not pass through the holes 11, fall on the disk 1 in an inclined direction. Otherwise, they may slide down and accumulate in the heavy object discharge zone 7. In addition, the above-mentioned lightweight waste that has moved to the discharge area 4 is slightly floated up due to the discharge pressure of the air blown out from the through holes 11, and is transported as it is as the disk 1 rotates, and is dammed by the dam plate 6 and removed from the lightweight waste. It is accumulated in the discharge zone 5. In this way, after the waste including large and small, light, heavy and miscellaneous as mentioned above is supplied to the supply zone 2,
They are continuously and extremely quickly sorted and accumulated in each zone into three types: fine, heavy, and light/heavy.

When a clogging removal brush 61 is attached to the weir plate 6, the brush 61 relatively slides on the surface of the disk 1 as the disk 1 rotates, thereby automatically removing waste clogged in the through holes 11. removed.

(Example) Next, an example will be described. In FIG. 1 and FIG. 2, the disk 1 has a cap-shaped shape, the entire body is inclined along the meridian L, and the center thereof is the discharge zone 5, 7.
It is supported by a central drive shaft 12 that is inclined to the side. The reason why the disk 1 is shaped like a hat is to increase the actual angle of inclination of the disk surface along with the overall inclination, thereby increasing the efficiency of discharging each waste to the discharge zones 5 and 7. However, flat plates are not excluded. The central shaft 12 is rotatable around its axis by a motor 13,
As the central shaft 12 rotates in the R direction as the motor 13 is driven, the waste supplied onto the supply zone 2 of the rotating disk 1 is sorted in the manner described above. Above the supply zone 2 lies the end of another supply conveyor 21 from which waste is continuously supplied to the supply zone 2 . The waste to be sorted is as mentioned above, but furniture,
If large waste materials such as tatami mats, carpets, and other electrical equipment are included, it is desirable to crush them in advance.

The lower part of the disc 1 corresponding to the suction area 3 is equipped with a storage hopper 31 that also serves as a suction hood.
The upper edge of the opening of the hopper 31 is in contact with the back surface of the disc 1, so that they can come into sliding contact with each other when the disc 1 rotates. Further, a suction duct 32 is led out from the side of the hopper 31 and connected to a suction blower 33. Furthermore, a rotary valve 34 is connected to the lower end of the hopper 31 to successively discharge the earth and sand accumulated in the hopper 31.

An air supply hood 41 is installed at the lower part of the disk 1 corresponding to the discharge area 4, and the upper edge of the opening of the hood 41 contacts the back surface of the disk 1, allowing relative sliding contact when the disk 1 rotates. Further, a discharge duct 42 of the suction blower 33 is connected to the side of the hood 41, so that the discharge air accompanying the drive of the suction blower 33 is introduced into the hood 41. In this way, the discharge duct 4 of the suction blower 33
2 to the hood 41, it is economical and the device becomes compact, which is advantageous.

A peripheral wall 14 is formed at the peripheral edge of the disc 1, and the peripheral wall 14 is open at the lower part of the disc 1 in the direction of inclination. The peripheral wall 14 can prevent waste from spilling around the disk 1. Also,
A weir plate 6 is installed at the upper part of the disk 1 extending from the center of the disk 1 toward the bottom in the inclination direction along the meridian L, and the weir plate 6 divides the open portion of the peripheral wall 14 into left and right sides. The left and right compartments are respectively a light waste discharge zone 5 and a heavy waste discharge zone 7. The weir plate 6 is bifurcated from the middle, and this is to make the discharge zones 5 and 7 clear and to facilitate the individual removal of the sorted waste. A conveyor (not shown) is arranged at the outlet of each discharge zone 5, 7, and the sorted waste is successively conveyed to the next process. Further, a brush 61 for preventing clogging is attached to the weir plate 6, and the brush 61 is brought into sliding contact with the surface of the disk 1, so that as the disk 1 rotates, the through holes 11...
We are trying to gradually remove the waste that is clogging the area.

Incidentally, the inclination angle, rotational speed, etc. of the disk 1 can be adjusted, which makes it possible to perform appropriate sorting adjustment according to the state of the waste, and is thus preferably employed.

(Effects of the invention) As described above, the waste sorting device of the present invention can process the above-mentioned miscellaneous wastes through the rotation of the disk 1 and the functions of the suction area 3 and the discharge area 4 for subsequent recycling processing and incineration. This is an extremely simple and rational way to select waste materials suitable for treatment or landfilling, and greatly contributes to labor saving and efficiency at waste treatment plants. Furthermore, since the device is simple, it can be supplied at low cost, and therefore, the social utility value of the present invention is extremely large.
