In FIGS. 1 and 2, 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
It is rotatably supported in the same direction (indicated by the arrow A) in the vertical direction from the waste input side to the discharge side of the selected large waste W3 horizontally in the same plane in parallel with each other in 0. 4 rows of rotors 20, ... And these rotors 2
.., and a discharge portion 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 to one end thereof, and square holes 25a , 28a fitted into the angular shaft 21 and vertically adjacent to each other. Large-diameter wheel body 25 and both large-diameter wheel bodies 2 made of hard rubber or soft plastic arranged in a complicated state
It is composed of a small-diameter wheel body 28 interposed between Nos. 5 and 25. The large-diameter wheel 25 has a hemispherical projection 26 on one surface, ...
・ Two in the radial direction and eight rows in the circumferential direction are projected, and the other surface is a flat surface. When the thickness of the small wheel 28 serving as a spacing piece is changed, the distance between the projections 26, ... And the flat surface of the adjacent large diameter wheel 25 is changed, and the size of the sieve is just changed. Get the same effect. On the peripheral surface of the ring body 25, the ridges 2 that generate wind
5b is provided at regular intervals, also ribs causing wind on the peripheral surface of the small wheel body 28 that have been plurality. Protrusion 26, ...
Has a role of determining the size of the sorted product and a role of causing a wind to make the lightweight object slide on the rotor 20 together with the wind generated by the protrusions 25b. In addition to the hemispherical shape, a cubic shape, a truncated pyramid shape, and a truncated cone shape are also included. It can have various shapes such as. Further, the square shaft 21 and the holes 25a , 28a into which the square shaft 21 is fitted are not limited to the square cross section and may be any polygonal cross section.

On the loading side of the frame 10, a conveyor C1 for loading waste such as construction waste material is continuously provided, and on the discharging side, a ramp way 16 for discharging large waste W3 is connected, and both side walls 11 are provided. The rotor 20 is supported via a bearing 11a between them, and the rotary drive device 3 is provided outside the one side wall 11.
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 addition to this, as the rotation drive device, a chain is stretched over a sprocket with a rotor and a sprocket with a motor, and an idling sprocket is appropriately interposed to rotate the rotor 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 if it is a light cassette such as a radio cassette tape, a video cassette tape, or a nylon string, it does not completely wrap around. It can be floated and discharged, and a bundle of ropes and wires is successively taken over and discharged by the large-diameter wheel 25 and its protrusion 25b. Further, even if wastes or other substances having a high water content are mixed in the waste W, they can be dropped downward without causing clogging, and this can be used for sieving compost. When the rotation of the rotor 20 is increased, the sieve mesh formed by the projection 25b, the side surface of the large diameter wheel 25 and the ridge 25b and the peripheral surface of the small wheel 28 becomes relatively fine, and when the rotation is decreased, the sieve mesh becomes relatively small. The sieve mesh becomes coarse.
Furthermore, it has a structure that is unlikely to cause clogging or damage, resulting in low noise,
With a low vibration, it is possible to continuously sort a large amount of construction waste materials, 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 after sorting can be performed immediately. In the four rows of rotors 20, ... Which are rotated in the same direction A, for example, they are rotated independently in the opposite direction between the third row and the fourth row to temporarily stall the flow. A rotor, or an auxiliary air blowing nozzle that blows air from the rear (supply side) gap of the small-diameter wheel body 28 where the descending air flow is likely to occur, is provided in the lower part, or a punching board is supplemented below. It is also possible to take appropriate measures depending on the type of waste.

The large-diameter wheel 25 has a columnar shape as shown in FIG. 3 other than that shown in FIG. 1 or a polygonal shape such as an octagon as shown in FIG. What you did,
There are those having a large number of wind gusts as shown in FIG. 5, and those having a columnar shape as shown in FIG. A circular protrusion 26 (of course, the shape should be limited to a circle) is provided on one side surface or both side surfaces, and a square hole 25 for fitting with the prism 21 is provided.
a is provided. It is appropriately selected according to the type of waste W.

Several sorters 1 of the above-mentioned embodiment are combined in series, for example, as shown in FIG. 7, and the rotation speed of the rotor 20 is gradually decreased from the supply side to the discharge side to reduce the size of small and medium-sized waste. The objects W1 and W2 are further configured to be sequentially sorted into a minute waste w1, a small object W1, and a medium object W2. In this case, although the configurations of the rotors 20, ... And the rotation driving device 30 of the small object sorting group U, the small object sorting group S, and the medium object sorting group M are the same, the inverter motors 31U and 31S of each group are the same. , 31M in rotation speed. If the number of rotations is increased, the mesh size becomes smaller, and if the number of rotations is decreased, the mesh size becomes larger. In addition to the above-mentioned series arrangement, it is possible to add a level difference in a stepwise manner so as to be gradually lowered from the supply side to the discharge side.

As another application example, as shown in FIG. 8, the size of the mesh between the adjacent wheels 25, 25 is changed depending on the presence or absence of the protrusion 26 on the side surface of the large diameter wheel 25 of the rotor 20. It can also be configured. That is, in the small object selection group U ′, one protrusion 26 is provided per row on one side surface of the large-diameter wheel body 25, and two protrusions 26, 26 per row are provided on the other side surface.
Is provided so that one protrusion 26 on one side surface of the adjacent wheel body 25 is passed through between them. In the small object selection group S ′, one side surface is a flat surface and the other side surface has two protrusions 2 per row.
6 and 26 are provided so that the mesh size is slightly larger than that of the group U '. In addition, in the medium-sized material selection group M ′, both side surfaces are flat surfaces so that the mesh size is further increased. In this application example, the large-diameter ring body 25 having the same size is used, but of course, the sieve mesh can be changed by changing the size of the large-diameter ring body 25 or the width of the small-diameter ring body 28. . In order to reduce the manufacturing cost and the type and number of spare parts, it is a good idea to use the large-diameter and small-diameter rings 25 and 28 of standard size and to make the protrusions 26 removable. A change in the relative size of the sieve mesh depending on the rotation speed can be added to the change in the actual size of the sieve mesh. Furthermore, air is blown up from below the rotor to sort out lightweight objects such as paper and plastic film with a suction hood above the rotor, and at least the rotor speed of at least one row is increased and discharged to the discharge side. Large objects can be sorted by centrifugal force into light and heavy objects by using specific gravity. It goes without saying that the sorting machine 1 of the present invention can be used not only for sorting waste, but also for sorting various agglomerates, compost and the like.

[0015]

As described above, according to the sorting machine of the present invention, it is possible to prevent clogging of a wide range of waste materials from construction waste materials to leftover food from restaurants and compost of farmers, and to those that are mixed. It is possible to continuously sort a large amount of at least two kinds without causing it, and if it is light, it is possible to send ropes, strings, and various tapes in the rotating direction of the rotor without causing wrapping. Also, it can be used for sieving even if it is damp or wet without causing clogging. In addition, the operation can be performed with low vibration and low noise, and there are few restrictions on the installation site, and the installation foundation work can be simple and economical.
