Abstract

PURPOSE:To reliably separate various types of waste different in weight into two different-size groups by forming numerous protrusions curved in a backward movement direction on rows of rotors for transporting a large-size waste sequentially so that these protrusions become mutually intermeshed with the adjacent ones. CONSTITUTION:A waste selector 1 is composed of main parts such as a belt conveyor C2 for transporting small and intermediate-size wastes W1, W2 and rows of rotors 20 for transporting large-size wastes W3 sequentially in a frame 10 erected above the belt conveyor C2. Each rotor 20 is composed of an angular shaft 21 with a gear fixed on one end, a wheel 25 with finger-type projecting elements 26 mounted on the peripheral surface and also with a square hole for engaging with the angular shaft 21, and spacer pieces intervened between these wheels 25. In addition, each protrusion 26 has semispherical projections 26a on each face and each other face which is flat. In addition, each protrusion 26 is curved backward in such a manner that the adjacent protrusions become intermeshed with the other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste sorter for sorting various wastes and composts from construction wastes to leftover food in restaurants according to size.

[0002]

2. Description of the Related Art Conventionally, as a waste sorter of this type, there is a sorter of the present applicant (see Japanese Patent Laid-Open No. 4-176374). As shown in FIG. 6, a plurality of spiral bodies 63 are arranged in a plane in a frame opening 62 having a screen 61 for sorting small waste W1 stretched on the bottom surface, and driven to rotate toward the discharge side of large waste W3. The medium-sized waste W2 into the spiral body 6
It is dropped between Nos. 3 and 63 to send out what is on the screen 61 in the spiral advancing direction, which has been well received by construction waste processing companies.

[0003]

A rope, various cords, and tapes are mixed in the waste, and the spirals are wound around the spiral during the sorting operation, and the operation must be interrupted for removal. In addition, the screen may become clogged if leftover food or compost that is damp or wet is mixed in, and it may become impossible to separate fine particles such as earth and sand. The present invention solves the above-mentioned problems of the prior art, and even if a wide range of wastes from construction waste materials to restaurant leftovers and farm compost are mixed, a large amount can be continuously obtained without causing clogging. It is sorted into two sizes, and if it is light, it can be sent out in the direction of rotation of the rotor so as not to wind ropes, strings, tapes, and sieves wet and wet leftovers and compost. The purpose is to provide a sorter for waste that can be separated.

[0004]

In order to achieve the above-mentioned object, the waste sorters are arranged in parallel and substantially parallel to each other from the waste input side to the sorted large-size discharge side. The rotor is composed of a plurality of rotors that are rotationally driven in the same direction from the input side to the discharge side, and each rotor is provided with a large number of finger-shaped projections on the peripheral surface so that adjacent ones are intertwined with each other. In addition, each finger-like protrusion is characterized by forming a plurality of protrusions so as not to interfere with those adjacent to the side surface.

By curving the finger-shaped protrusions in the backward direction with respect to the rotation direction of the rotor, the effect of preventing the winding of the cord, tape or rope and the sieving effect can be enhanced. Further, if the rotor is composed of a square shaft and a plurality of ring bodies that have square holes that fit into the square shaft and that have finger-shaped projections provided around the circumference, the key can be omitted and the manufacturing cost can be reduced.
Easy to maintain. Also, if the rotation of about half of the rotor on the input side is made faster and the rotation of the remaining rotor on the discharge side is made slower,
The particles falling from between the finger-like protrusions can be further divided into two types: one with a small particle size on the input side and one with a large particle size on the discharge side. Separation and transport of light items such as tape and tape to the discharge side will be more reliable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A waste sorter as a representative embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a vertical sectional view of a waste sorter of the present invention, and FIG.
Fig. 3 is a partial horizontal sectional view taken along line II-II, Fig. 3 is an elevational view of the rotor body, Fig. 4 is a sectional view taken along line IV-IV in Fig. 3, and Fig. 5 is a finger of another embodiment. FIG. 3 is an explanatory view of a protruding member.

1 to 4, a waste sorter 1
Is a rectangular frame 10 erected on a belt conveyor C2 for carrying out small and medium-sized wastes W1 and W2, and the frame 1
4 parallel to each other in the same plane horizontally from the waste input side to the discharge side of the selected large waste W3 in four rows rotatably supported in the same direction (indicated by arrow A). .., a rotary drive device 30 for the rotors 20, ..., And a discharge part 16 for the large waste W3 in the rotation direction A.

Each rotor 20 has a square cross-section angular shaft 21 having a gear 33 fixed at one end, and a square hole 25a fitted into the angular shaft 21 so that the rotor 20 and the adjacent ones are intertwined with each other. A ring body 25 made of hard rubber or soft plastic in which twelve finger-shaped protrusions 26 that are recedingly curved on the peripheral surface are provided, and a spacing piece 2 provided between the ring bodies 25, 25.
8 and. The protrusion 26 has two hemispherical protrusions 26a, ... On one side, and the other side is flat. When the thickness of the spacing piece 28 is changed, the protrusion 26a,
... and the distance between the adjacent protrusions 26 are changed to obtain the same effect as just changing the size of the mesh of the sieve.

A conveyor C1 for introducing waste such as construction waste is connected to the input side of the frame 10, and a ramp way 16 for discharging large waste W3 is connected to the discharge side. The rotor 20 is supported by the bearing 11a on the outer side of the side wall 11 and the rotary drive device 3
0 is set. The rotation driving device 30 includes a motor 31.
And a pinion gear 32 with an output shaft thereof, a rotor-equipped gear 33 meshing with the pinion gear 32, and an idler gear 34 between the adjacent rotor-equipped gears 33, 33. The four rotors 20, ...・ All are rotated in the direction of arrow A.

In the waste sorter 1 of the present embodiment, the air flowing to the discharge side is generated during operation, and a light cassette such as a radio cassette tape, a video cassette tape, or a nylon cord does not completely wrap around. It can be floated and discharged, and the bundle of ropes and wires can also be finger-like protrusions 26 and their protrusions 26.
It is inherited one after another and discharged. Further, even if a large amount of water such as leftover food is mixed in the waste W, it can be dropped downward without causing clogging, and by applying this, compost can be sieved. When the rotation of the rotor 20 is increased, the protrusion 26a and the protrusion 2 are relatively moved.
The sieve mesh formed by 6 and 6 becomes fine, and the mesh mesh becomes relatively coarse when the rotation is lowered. Furthermore, it has a structure that is unlikely to cause clogging or damage, and can continuously sort a large amount of construction waste, household waste, business waste, restaurant leftover food, etc. into two sizes. If the crushing process is performed before the waste is put into the sorting machine 1, the processing process after the sorting can be performed immediately.

In addition to the above-mentioned embodiment, as shown in FIG. 5, protrusions 26'a, 26 "a are formed on both sides of the protrusions 26 ', 26" so as to be intertwined with each other and to face each other. Alternatively, a trapezoidal key or a truncated cone projection can be formed instead of the hemispherical projection. In addition, the one in which the wheel body and the spacing piece are integrated is also used. In addition, the rotor 20 in the representative embodiment,
If the rotation speed of the two rows on the input side of ... Is rotationally driven faster than the rotation speed of the two rows on the discharge side, the faster the rotation, the finer the gap between the finger-like protrusions, and the more accurate the size of the sieve. The effect of making the eyes smaller can be obtained, and it is possible to separate into those having a small particle size on the input side and those having a large particle size on the discharge side. This is a large amount of water that could not be separated using a conventional screen type sieve (sand is usually difficult to sort if it is 10 to 15% or more), compost, food-related residues, stones that have been exposed to rain and dust prevention watering. It is particularly effective for building materials mixed waste such as bulk board powder. Furthermore, the rotor 20,
When air is blown upward from below under the air duct, it is possible to reliably send out paper scraps, plastic sheets, films, tapes, and other lightweight items to the unloading side.

[0012]

As described above, according to the waste sorting machine of the present invention, even if a wide range of wastes such as construction wastes, leftover foods of restaurants and composts of farmers are mixed, a large amount can be continuously produced. It can be sorted into two sizes, and it can be floated by the wind generated by the finger-shaped protrusions that rotate so that light ropes, cords, and tapes do not wind around the rotor, and can also be wetted. It also sifts leftover food or compost that is moist or damp.
