Description

[Detailed description of the invention] [Industrial application field] The present invention is widely used in, for example, home appliances from municipal waste, and is suitable for collecting chips from lead wires that will be generated as garbage. About.

[Conventional technology and its problems]

Recently, municipalities have spent considerable money on the treatment of municipal solid waste. As a method of this processing, for example, eddy current is generated in aluminum scraps on the belt by alternating magnetic flux generated by rotation of a rotating magnet from aluminum scraps such as juice cans, and a repulsive magnetic force between the magnetic flux and the alternating magnetic flux of the rotating magnets. For example, there is known a device in which aluminum scrap is separated from a discharge end of a driven roller made of a non-conductive material of a belt conveyor in a belt running direction to separate and collect the aluminum scrap. Many lead wires coming out of the copper wire are covered with vinyl or the like around the copper wire, but these debris are collected on the aluminum debris collection side or collected on the ordinary waste debris side. If it is poor, especially when it gets into the aluminum collection part, vinyl dust and copper wire coated on it will be mixed, but this Thus reducing the recovery Collection rate of the original aluminum scrap.

[Problems to be solved by the invention]

The present invention has been made in view of the above-mentioned problem, and has a device for collecting scattered scraps that are particularly troublesome to collect from municipal waste, for example, a swarf scrap that can collectively collect a large amount of lead wires from home appliances. The purpose is to provide.

[Means for solving the problem]

The above object is to provide a swarf collecting lump having a freely rolling shape and having a large number of pores, a belt conveyor inclined upward, and a swarf collecting lump at a lower end of the belt conveyor. And a hopper disposed above the belt conveyor and containing refuse containing refuse to be collected, and refuse supplied from the hopper onto the belt conveyor. In the process of raising and lowering the debris while the debris collection lump rolls on the belt conveyor, collecting debris from the debris on the belt conveyor by engaging the pores, The small piece is characterized in that the small piece waste collecting mass is gradually increased, and when the weight becomes so large that it is no longer conveyed upward, it rolls downward and is received by a receiving member. Achieved by a waste collection device.

[Action]

The lump collecting body having a freely rotatable shape rises while rolling to a certain height along with the traveling of the belt conveyor on the ascending slope. That is, when the conveying speed of the belt conveyor is higher than the rotational peripheral speed at which the small debris rolls downward, it is conveyed upward by the belt conveyor. For example, if debris such as swarf from lead wire is mixed in municipal solid waste, it may engage with or adhere to many pores opened in the debris collection mass, or As a result, the debris collecting body gradually increases in volume according to the collected amount. That is,
For example, if the debris collection mass is spherical, its diameter and mass are increased. In accordance with this volume, the rotational peripheral speed of the lump with the original litter collection lump as the core increases, and eventually rolls downward when the lump becomes higher than the conveyor speed of the belt conveyor, and the lower end of the lump collects. It is received by the receiving member and stopped here. This is transported to the strip waste collection section. Therefore, according to the present apparatus, it is possible to intensively collect, in particular, small pieces of waste from municipal waste in which various kinds of waste are mixed, so that the collection rate of other kinds, for example, aluminum waste can be improved.

〔Example〕

Hereinafter, a strip waste collecting apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a debris collecting device according to a first embodiment of the present invention. In the drawing, the collecting device is indicated by (1) as a whole, and a belt conveyor (2) is located at an upper portion thereof as shown. It is arranged to be inclined upward with respect to the traveling direction.
That is, the drive roller (3) is supported on the ground by the support (5), and the driven roller (4) is supported on the ground by the support (6). Thereby, it is arranged as an upward inclination as shown. The drive roller (3) is rotationally driven by a motor (7) via a belt (8) so as to rotate clockwise in the figure. Further, a receiving plate (9) for receiving the small debris collecting block (10) at the lowermost position is fixed to the ground near the lower end of the belt conveyor (2). The lump (10) is spherical according to this embodiment, for example, similar in shape to a bowling bowl with a smaller number of finger holes (although smaller in diameter). Above the belt conveyor (2), a municipal solid waste supply hopper (12) is provided.
Is housed. Further, a collecting hopper (11) for collecting the refuse discharged from the driven roller (4) is disposed below the collecting hopper (11).

The first embodiment of the present invention is configured as described above. Next, this operation will be described.

For example, a large amount of municipal waste is put into the hopper (12) by a dump truck or the like. The discharge holes may be provided with an appropriate gate and supplied to the appropriate amount of the belt conveyor (2), or may be supplied continuously if the discharge opening has an appropriate size. By driving the electric motor (7), the belt of the belt conveyor (2) travels in the direction of the arrow, whereby the municipal solid waste G discharged from the hopper (12) is placed on the upper traveling portion and is upwardly transported rightward in the figure. Is done. On the other hand, when the belt conveyor (2) is stopped on the receiving plate (9) as shown in the drawing, the belt conveyor (2) is stopped by contacting the receiving plate (9), but the belt conveyor (2) is conveyed upward by the traveling of the belt conveyor (2). Is done. At this time, the rotational peripheral speed of the rolling, which rolls below the lump-recovery lump (10), changes depending on the frictional force on the belt and the size of the diameter, but initially the rotational peripheral speed is the belt rotational speed. Since it is lower than the conveyor conveyance speed, it is conveyed upward by the conveyor belt conveyor. At this time, as shown in FIG.
The scraps l contained in the body, for example, the scraps l of lead wires generated from home appliances, enter or engage with the many pores (10a) of the ascending mass (10) while rolling. Attach to the mass (10), whereby the mass (10) gradually increases its volume. That is, the small chip collecting mass (10), which has now attached or engaged a large amount of small chips (L) to the small holes, has increased its rotational peripheral speed, and finally has a belt conveyor (2). Can not be raised. That is, the lump collecting mass (10) having a large amount of litter l engaged thereon rolls downward on the belt conveyor (2) and comes into contact with the receiving plate (9). Then, the belt conveyor (2) may be stopped, and the lump (10) which has collected as much as possible this debris may be conveyed to the debris collection section. The same action can then be carried out immediately by bringing a new, similarly shaped mass (10) to the lower end of the belt conveyor (2). Other waste G 'not collected by the lump (10) is the belt conveyor (2).
And is discharged from the driven roller (4) to the refuse collection hopper (11), and is conveyed from this to an appropriate collection processing step.

As described above, according to the present embodiment, it is possible to selectively collect the small debris 1 such as a lead wire coming out of a home electric appliance, which has been regarded as a problem in the related art. It is possible to further improve the collection and selection rate of various types of refuse, for example, the collection and selection rate of aluminum scrap, as compared with the related art.

FIG. 3 shows a debris collecting apparatus according to a second embodiment of the present invention. This apparatus is generally indicated by (20), and a belt conveyor (21) is directed upward as in the first embodiment. It is arranged at an angle. That is, the drive roller (22) is supported on the ground by the support (28), and according to the present embodiment, the cylindrical body (23) as the driven roller is made of a non-conductive material. 31) supported on the ground. Therefore, the belt conveyor (21) is disposed inclined upward. The drive roller (22) is rotationally driven in a direction indicated by an arrow at a predetermined speed by a motor (26) via a belt (27).

In the cylindrical body (23), a rotating magnet (24) having N poles and S poles alternately provided on the outer peripheral edge is concentric, but spaced apart from each other. And the rotating magnet (24) is
The motor (30) is driven to rotate in the direction of the arrow at a higher speed than the first motor (26), that is, in the same direction as the cylinder (23).

Further, below the cylindrical body (23) is disposed dust container (34), which partition wall (35) (36) (37) (38) by the right in the order aluminum dust collecting chamber A, normal Garbage collection room B
And an iron scrap collecting chamber C.

A hopper (33) for storing municipal waste is disposed above the belt conveyor (21), and a lump (40) is placed at the lower end of the belt conveyor (21).
The receiving plate (32) for receiving at the lower end position of the is provided. The lump (40) of the present embodiment is different from the first embodiment in that it is obtained by compacting small chips into a bowl. For example, it is formed by compacting a large number of lead wires coming out of home appliances into a round shape like a diaper. Such a lump (40)
Has many pores formed between the compacted lead wires. The second embodiment of the present invention is configured as described above. Next, this operation will be described.

The belt conveyor (21) is driven to travel in the direction of the arrow.
The lump (40) is conveyed together with the lump on the belt conveyor (21) and rises while rolling in the direction of the arrow to a certain height. That is, since the transport speed of the belt conveyor (21) is higher than the rotational peripheral speed of rolling down on the belt conveyor (21), the belt is conveyed upward. As in the first embodiment, the chip litter, for example, a lead l of a home appliance is collected by being locked or inserted into the gap between the compacted leads, and collected up to a certain height. The debris l (ell) discharged from the hopper (33) during the rolling ascent is engaged with the small hole by the rotation of the debris collection mass (40), and is sequentially inserted by insertion.
Increase its mass and volume. If it does not finally rise, it may be removed from the belt conveyor (21) and brought to the small chip collecting section. Then, a similar mass (40) may be brought to the lower end position of the belt conveyor (21). As shown in FIG. 3, the frictional coefficient and the drag with the belt conveyor (21) fluctuate while the small debris collecting mass (40) is rotating as shown in FIG. Depending on the size of the chip litter, which rises while rolling again, and furthermore, the small chip l
(L) is engaged or inserted between them to further increase the volume, and rolls downward to abut against the receiving plate (32) as shown. In addition, this phenomenon is the same also about the small piece waste collection lump (10) of 1st Example.

The municipal waste G contains aluminum waste m, iron waste f, paper waste and plastic waste g. When this reaches the uppermost point of the cylindrical body (23), it contains a rotating magnet. Alternating magnetic flux is received by the N and S poles at the periphery of (24), thereby generating an eddy current in the aluminum chips m and receiving a repulsive force due to the interaction between the resulting magnetic flux and the alternating magnetic flux of the rotating magnet (24). , The aluminum collection chamber A of the refuse container (34) receiving the popping force as shown by the locus c.
Collected to Further, normal waste, that is, paper waste and plastic waste g, naturally fall from the belt end and are collected in the normal waste collection chamber B. Further, when the iron waste f reaches the area of the rotating magnet, it is attracted to the N-pole or S-pole and is transferred as it travels along with the movement of the belt conveyor (21). As shown by the trajectory e, the iron scrap f is collected into the iron scrap collection chamber C.

Although the present embodiment is configured as described above, it is apparent that the same effects as in the first embodiment can be obtained.

Although the embodiments of the present invention have been described above, the present invention is, of course, not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the spherical molded body (10) or the spherical lump (40) obtained by compacting the swarf itself is described as the lump, but the lump may not be spherical. For example, it may be cylindrical. A large number of holes or slits may be formed in this. In addition, any shape may be used as long as it can roll freely.

[Effects of the invention] As described above, according to the present invention, it is possible to reliably select the small chip waste that has been considered difficult to recover, for example, lead wire dust that appears in large numbers from home appliances. In addition, it is possible to increase the collection rate of other types of refuse such as aluminum refuse.
