Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is mainly for separating and recovering non-combustible lumps (concrete pieces, stones, cables, wires, metal pieces, etc.) and combustible materials (wood chips, paper chips, etc.) in industrial waste. The present invention relates to a suitable inclined brush conveyor type sorting machine.

[0002]

2. Description of the Related Art Generally, an incline type sorting machine (incinerator) is used for separating and collecting non-combustible lumps (concrete pieces, stones, cables, wires, metal pieces, etc.) and combustible materials (wood chips, paper chips, etc.) in industrial waste. An inclined conveyor type sorting machine referred to in Japanese Unexamined Patent Publication No. 61-501685, etc., a rotating shaft sorter with a brush, and the like are used.

The ink-line type sorting machine comprises a belt conveyor with a vibrator, which is slantly arranged in the width direction and the longitudinal direction, and a single or a plurality of rows of motor-operated rotating chain curtains which are slightly slanted in the conveyor width direction. It has a structure in which a weight group is hung down at the bottom of each chain, and waste is thrown in from the side of the longitudinal end of the belt conveyor and vibrates with a vibrator attached to the belt conveyor. On the upper surface of the heavy goods, the heavy goods move in the width direction of the conveyor, pass through the rotating chain curtain, fall from the belt side end (lower inclined part), and are collected. Has become.

On the other hand, in the rotary shaft sorter with a brush, a combustible material (lightweight material) carried out from the end portion of the conveyor is mixed with the combustible material at the end portion of the conveyor or the ink line type sorter. It is provided to separate incombustibles.The structure is such that brushes of appropriate length are planted on the circumference of the rotation shaft driven by a motor, and the weight of the waste that falls from the end of the belt conveyor The objects pass through the brushes and fall as they are, while the lightweight objects are discharged by the rotating brush.

[0005]

Inclined conveyor type sorters such as incline type sorters, rotary shaft sorters with brushes, etc. have the function of separating and collecting heavy and light items as described above. In the case of an incline type sorting machine, incombustible materials (strings such as cables and wires) may be mixed in the combustible materials (lightweight materials) carried out from the end of the conveyor. As a countermeasure against this, a method of disposing the brush rotary shaft sorter or the like at the end of the conveyor of this incline type sorter has been adopted. However, in the conventional brush rotary shaft sorter, cables, wires, etc. Strings may be wound around the rotary shaft and become unusable, which is a problem that it is not suitable for separating waste containing cables, strings, wires, chains, and the like.

The present invention has been made in view of the above-mentioned conventional circumstances, and does not cause a trouble in which a cable, a string, a wire, a chain, or the like is mixed with a waste material that is wound around the cable, the string, the wire, the chain, or the like. It is intended to provide an inclined brush conveyor type sorter capable of separating heavy articles and light articles.

[0007]

SUMMARY OF THE INVENTION An inclined brush conveyor type sorting machine according to the present invention is a motor drive type in which an endless chain meshing with a pair of horizontally arranged sprockets is attached with a downward inclined brush of a constant width. An inclined brush conveyor and a partition plate longitudinally disposed on both sides of the conveyor at positions contacting the outer ends of the inclined brushes, and among the wastes introduced on the inclined brush conveyor, a heavy object is the inclined portion. It is characterized in that it is structured such that a lightweight object is conveyed through the brush while remaining on the conveyor by the partition plate and dropped from the end of the conveyor where the inclined brush and the partition plate are separated from each other. It is a thing.

[0008]

In the present invention, the brush for receiving the waste is inclined downward in order to enhance the sorting effect of the waste dropped on the inclined brush conveyor. That is, when the brush is inclined, both the lightweight and heavy objects move to the tip of the brush when the waste rolls or slides down,
This is because the heavy object easily passes through the brush due to its own weight, and the light object is easily discharged from the conveyor turn section without staying on the brush conveyor. The downward angle of the inclined brush conveyor brush is not particularly limited, but is generally about 45 degrees.

The driving mechanism of the inclined brush conveyor may employ a method of driving a sprocket or a gear via a variable speed reducer or the like. As a brush attachment means, for example, a brush in which bristles are planted on an appropriate member is attached to an endless chain through an attachment. The brush may be made of nylon, wire brush, piano wire, or the like, but when using a piano wire, it is preferable to attach it so as to have flexibility in consideration of durability.

The partition plates arranged in the longitudinal direction on the both sides of the inclined brush conveyor at positions contacting the outer ends of the inclined brushes,
This is to prevent the waste introduced on the inclined brush from dropping on both sides of the belt conveyor and to convey and discharge the lightweight material remaining on the brush to the end of the conveyor. Therefore, the partition plate is usually installed vertically, but it may be installed at an angle.

The waste introduced on the inclined brush conveyor rolls or slides on the inclined brush, while heavy objects (incombustibles) push the brush to spread and pass through to fall below the conveyor. The object (combustible material) is stopped by the partition plate and at the same time conveyed while being carried on the conveyor, and falls from the end of the conveyor where the inclined brush and the partition plate are separated from each other. Therefore, even if cables, strings, wires, chains, etc. are mixed in the waste, not only can these be sorted into lightweight and heavy items, but there is no trouble such as the strings clinging to the machine.
