Next, the operation of the embodiment of the refuse disposal apparatus of the present invention will be described. First, the mixture 2 composed of the exposed garbage a and the bagged garbage b is collected at one place, and is put into the charging hopper 1, and the crusher disposed on the way of being transferred by the conveyor 3 for transferring the mixture of the exposed garbage and the bagged garbage. A case will be described in which the bag-containing waste b is broken by the bag machine 4 to obtain bag-break waste c.

The mixture 6 composed of the exposed garbage a and the garbage crushed c accumulated in the latter stage of the bag crushing machine 4 is contaminated by the conveyer 5 for transferring the mixture of the exposed garbage and the crushed garbage to the garbage of the cylindrical rotary screen 7. It is transferred to the supply port 7a and supplied to the cylindrical rotary screen body 7. This cylindrical rotary screen body 7
From the required mesh 7c around the entire body circumference, fine (small / dust-like trash) d such as cigarette butts, leftovers, disposable chopsticks, and other trash, and paper and trays, for example. , E.g., paper containers, plastic containers, disposable diapers, iron cans, aluminum cans, glass bottles, etc., which can pass through the garbage e, and cannot pass through the mesh 7c from the garbage outlet 7b. For example, light and relatively large refuse f having a lunch box and other shapes is discharged.

The fine dust d and the dust e having a size that can pass through the mesh 7c of the cylindrical rotary screen body 7 below the mesh 7c of the cylindrical rotary screen body 7 are conveyed through the cylindrical rotary screen body mesh. The cylindrical conveyor 10 is carried out by the cylindrical rotating screen body and the garbage is conveyed through the cylindrical rotating screen body 9 provided below the belt-shaped conveyor 9 for carrying out the garbage. It is sorted into the shape dust e. The fine dust d that has passed through the mesh of the mesh conveyor 10 is transferred to the mesh conveyor 1.
The belt-like conveyor 11 is placed on a mesh-shaped conveyer mesh-passing dust-and-adsorptive-garbage unloading belt conveyor 11 installed at the lower part of the conveyor belt 0, and is collected by the mesh-conveying dust-easy-adsorptive dust collection box.

Easily adsorbable trash g
And hardly adsorbable dust h, such as iron cans, aluminum cans, and glass bottles, which fall on the ring-shaped interference member 16.

The easily adsorbable dust g is placed in a concave space 15b which can be an opening surface on the upper surface side of the drum type suction-type rotary sorting body 15 of the drum body 15c. The drum body 1 is adsorbed on the surface of the drum body 15 and is rotationally conveyed at a constant speed in the arrow X direction.
When reaching the shielding portion other than the concave space portion 15b of FIG. 5c, the suction force is released, the dust passes through the mesh-shaped conveyor mesh, and falls into the strip-shaped conveyor 11 for carrying out easily adsorbable dust, and is conveyed by the strip-shaped conveyor 11 to be removed. It is collected in the mesh-passing trash / easy-adsorbing trash collection box 12.

The hardly adsorbable dust h, which is not affected by the suction force, is carried out by the hardly adsorbable dust carrying belt conveyor 17, and is separated by the magnet roll body 18 into magnetic dust i and non-magnetic dust j. You. The magnetic debris i such as an iron can among the hardly adsorbable debris h magnetized on the magnet roll body 18 is demagnetized by the demagnetization unit 18b and collected in the collection box 20, and Non-magnetic dust j, such as an aluminum can or a glass bottle, which is not magnetized on the magnet roll body 18 among the hardly adsorbable dust h, is carried out by the belt conveyor 22 for carrying out the non-magnetic waste.

When the non-magnetic dust j, such as an aluminum can or a glass bottle, carried out and discharged by the belt conveyor 22 for carrying out the non-magnetic waste, when reaching the discharge end, the blowing nozzle of the wind-pressure type weight-difference sorter 23 is used. The dust (aluminum can) k having a low specific gravity, for example, of the nonmagnetic dust j is blown off toward the discharge port 25 a through the blower tube 25 by the exhaust air pressure constantly blown out from the portion 23 b in a constant direction at a constant pressure. The waste is collected in a small-weight (aluminum can) waste collection box 27.
In addition, for example, dust having a large specific gravity such as glass bottles.
Is collected in a waste collection box 24 having a large specific gravity (such as glass bottles) due to its own weight.

In the garbage disposal apparatus configured as described above, for example, the bagged garbage of the exposed garbage and the bagged garbage put into the input hopper 1 is crushed by the garbage bagging machine 4 to break the bag. And from the mixture of the bag-breaking garbage and the exposed garbage,
Alternatively, fine (small / dust-like trash) dust that passes through the mesh of the cylindrical rotary screen body 7 from only the exposed trash, such as cigarette butts, leftovers, disposable chopsticks, and other trash,
Garbage of a size that can pass through the mesh, such as paper, trays, paper containers, plastic containers, disposable diapers, and light and relatively large garbage that cannot pass through the mesh, such as lunch boxes and other shapes , Magnetic cans such as iron cans, non-magnetic wastes of low specific gravity such as aluminum cans, and non-magnetic wastes of high specific gravity such as glass bottles. Can be reliably collected by each collection box.

[0031]

The refuse disposal apparatus of the present invention can easily and reliably sort and sort all kinds of garbage on a small scale without requiring any manpower at all, and reliably collect each of them. Garbage can be sorted, collected and processed efficiently, efficiently, safely and hygienically and easily by the efficient and efficient flow process.
As described above, if sorting and collecting can be reliably performed for each type of garbage, there is an effect that an extremely enormous power can be exerted in other post-treatments such as landfilling and incineration of garbage.
