Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waste sorting device that is most suitable for relatively small-scale waste treatment facilities.

In general, waste processing equipment separates ferrous materials from waste crushed by a crusher using an iron sorter, cullets are sorted by a cullet sorter, non-ferrous metals are sorted by a non-ferrous metal sorter, and combustibles are separated from the waste. The system discharges the waste to an incinerator or other facility.

By the way, in conventional waste processing equipment where iron sorters, current sorters, and non-ferrous metal sorters are installed separately and connected by a conveyor, etc. (well, in addition to requiring a large equipment space, each sorter requires a separate drum). , a drum support mechanism, a drum drive motor, etc. are required, which increases equipment costs.

Running costs were high, maintenance was difficult, and large-scale waste treatment facilities had to be installed.

The present invention has been made in view of the above-mentioned conventional problems.
A single rotary drum has a current sorting section on either the input opening side or the middle part of the drum, an iron sorting section on the other side, and a non-ferrous metal sorting section on the discharge opening side. Furthermore, it is possible to sequentially sort metals, ferrous metals, non-ferrous metals, and combustibles from the waste input through the input opening, saving equipment space and equipment costs.

This product provides a new waste sorting device that is advantageous for maintenance management, etc.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings, as shown in FIG.
A rotary drum 3 constructed by connecting an FRP drum 1 made of resin such as RP and a mesh-like lattice drum 2 into seven coaxial bodies with flanges la and '2a is arranged in an inclined state.
The flange 3a of the input opening 4 is supported from both sides by wheels 5, and the radial support is supported by wheels 6 on both sides of the lower surface of the body. By driving the drum 3, the drum 3 is rotated once in one direction (counterclockwise when viewed from the discharge opening 9).

The lattice drum 2 receives cullets 1 from the waste 11 fed by the immersion conveyor 10 which has entered the input opening 4.
The cows are sorted through a mesh, discharged downward, and stored in a hopper 14 via a chute 13.・As shown in FIG. 2, on the outer peripheral surface of the right side of the FRP drum 1, that is, the middle part between the input opening 4 and the discharge opening 9 of the drum 3, there is a
Permanent magnets 1 and 5 extending from the bottom surface of the drum 3 in the direction of drum rotation to the center of the top surface of the drum 3 are arranged at a predetermined gap. An iron take-out conveyor 17 extending from below the permanent magnet 15 to the outside of the discharge opening 9 is disposed on a support frame 16 that passes through the center of the inside of the drum 3 in the axial direction.
The ferrous metals 18 that have been sucked into the inner surface of the drum 3 and sorted from the waste J1 are released from the suction at the center of the upper surface of the drum 3 and are collected by a guide plate 19 and placed on the ferrous metal removal conveyor 17 through the discharge opening 9. It is sent outside and stored in a hopper 21 via a chute 20.

On the left side of the FRP drum 1, that is, on the discharge opening 9 side of the drum 3, as shown in FIG. 10 The moving magnetic field direction of the participating magnetic field generator 22 is FR
The direction of rotation of the P-drum 1 should be opposite to that of the P-drum 1. Also,
A partition plate 23 is arranged inside the diameter opening 9. Therefore, due to the rotation of the drum 3, the flammable materials 2° 4 are shifted in the direction of rotation of the drum 3, and the non-ferrous/metallic materials 25 are shifted to the moving magnetic field generator 2.
Due to the action of eddy currents generated inside the drum 3,
The combustible materials 24 are sorted by the partition and cutting plate 23 and discharged externally from the discharge opening 9.
are stored in a hopper 27 via a sheet 2'6, and non-ferrous metals 25 are stored in a hopper 29 via a sheet 28. , - as mentioned above, the waste sorting device i
According to this structure, when the waste material 11 is supplied by the mole feeding conveyor 10, the cullet 12 is first sorted by the grid 1° ram 2 and discharged from the mesh to the outside, and then to the FR.
The ferrous metals 18 are sorted by the permanent magnet 15 of the P drum 1 and discharged to the outside by the ferrous sorting coveyor 17.
Combustible materials 24 and non-ferrous metals 25 are separated by the moving magnetic field generator 22'' and discharged to the outside through the discharge opening 9 by the partition plate 23.

In the above-mentioned sorting process, the ferrous metals 18 are sorted and removed before the non-ferrous metals 25 are sorted.
Since the ferrous metals 1d are adsorbed to the non-ferrous metals 25, there is no need to operate the non-ferrous metals 25 generator 22 intermittently.

The continuous operation improves the sorting performance of non-ferrous metals 25.
Before the waste 11 reaches the FRP drum 1, the cullet 12 is sorted out and removed. Wear is reduced and durability is improved.

In the above embodiment, the iron sorting section is placed after the cullet and sorting section, but the iron sorting section may be placed before the cullet and sorting section. In this case, the FRP drum i is divided into two parts, one for iron sorting part and one for non-ferrous metal sorting part, and the lattice drum
The configuration includes intervening.

As is clear from the above description, the present invention has the following features.

One rotary drum includes a current sorting section, iron separation section,
Since the non-ferrous metal sorting section is rationally arranged, cullet, ferrous metals, non-ferrous metals, and combustible materials can be successively separated from waste, and the space required for gathering is small. In addition to reducing equipment costs and running costs, the system is also easy to maintain and manage, making it ideal for small-scale waste treatment equipment.
