[Prior art]

 An inclined conveyor type sorting machine used for separating and collecting non-combustible lumps (concrete pieces, stones, etc.) and combustibles (wood chips, paper chips, etc.) in industrial waste is generally an incline type sorting machine (see 61-501685, etc.) and has a function of separating and recovering heavy objects (mainly non-combustible lumps) and light objects (mainly combustibles).

The structure of a conventional incline type sorting machine is, as shown schematically in FIG. 5, a belt conveyor 1 which is arranged in an inclined manner in the width direction and the longitudinal direction, and a row or a plurality of rows which are arranged slightly obliquely in the conveyor width direction. It has a row of motor driven rotating chain curtains 2 and has a structure in which a weight group 3 is hung at the lower part of the chain, and a resin or aluminum pipe 3-1 is used for the weight. There is. The waste is loaded from the side of the longitudinal end of the belt conveyor 1 and vibrates by a shaker (not shown) provided inside the belt conveyor. On the upper surface of the belt, heavy objects move in the conveyor width direction. After passing through the rotating chain curtain 2, it falls from the belt side end (lower part of the slope) and is collected, and the lightweight items are directly conveyed by the conveyor and collected at the end.

[0004]

[Problems to be solved by the device]

 However, in the conventional Incline-type sorting machine, the gap between the pipes hanging under the rotating chain curtain is large, so flammable materials (wood chips, etc.) and small-grained objects to be rolled easily from this gap. May pass through this chain curtain, and light materials such as combustibles may be mixed into the sorted heavy objects (mainly non-combustible lumps), and sufficient accuracy for selecting non-combustible materials and combustible materials can be obtained. It had the drawback of not having it. Even if a brush or the like is attached to the tip of the pipes to reduce the gap between the pipes, if the amount of processing increases and the vibration of the belt surface due to an impact etc. occurs, the pipes bounce up and the gap between the pipes increases, The above problems cannot be solved sufficiently.

The present invention has been improved in order to eliminate the above-mentioned drawbacks of the related art. By using a brush curtain in place of the conventional chain curtain, it is possible to process a small-grained material to be treated through a gap between the pipes. In addition to solving the problem of objects or lightweight objects coming out of the conveyor, the conveyor ends the lightweight objects (combustible materials) carried out from the end parts transported by the conveyor and the thin non-combustible materials mixed in the lightweight objects. It aims to provide an inclined conveyor type sorting machine that can separate and collect heavy and light items more reliably by making it possible to sort by.

[0006]

[Means for Solving the Problems]

 An inclined conveyor type sorting machine according to the present invention comprises a belt conveyor inclined in the width direction and the longitudinal direction, and a rotary flexible brush which is slightly inclined in the conveyor width direction and is motor-driven in one or more rows. Of the waste introduced on the belt conveyor, which is equipped with a curtain, heavy objects pass through the rotary flexible brush curtain and are discharged in the width direction of the conveyor, while lightweight objects are carried out on the conveyor. In addition, a motor-driven rotary shaft selector with brush is arranged in the width direction of the conveyor at the end of the conveyor where lightweight items are carried out, and an air jet type wind separator is provided below the rotary shaft with brush. It is what

[0007]

[Action]

 The rotary flexible brush curtain is provided without gaps over the entire length of the belt conveyor. The drive system of this brush curtain is attached to an endless chain driven by a motor through a sprocket or a gear, as in the case of a conventional chain curtain. Means such as attaching to a chain can be used.

The brush-equipped rotary shaft sorter is provided to separate a combustible material (lightweight material) carried out from the end of the conveyor and an incombustible material mixed in the combustible material, and its structure is It is possible to use a brush in which a brush of an appropriate length is planted on the circumference of a rotation shaft driven by a motor.

The air-injection type wind sorter provided below the rotating shaft with a brush is provided to separate and collect combustible substances mixed with incombustible substances that drop after passing through the brush of the brush rotating shaft. Then, it is arranged so that air is jetted from the lateral direction to the falling object, and the combustible material is blown off and separated.

The object to be processed that rolls or slides on the inclined surface of the belt conveyor is stopped by the rotary flexible brush curtain disposed in the middle of the object, and is conveyed by the belt conveyor. At that time, since the lower end of the brush curtain is blocked by contacting the belt, a small object to be processed or a light object does not pass through the curtain. On the other hand, heavy objects push and spread the brush curtain, pass through the brush curtain, and fall from the lower part of the inclined surface of the conveyor.

[0011] The lightweight material (mixture of combustible material and incombustible material) conveyed by the belt conveyer is rotated by the rotating brush with a brush rotary shaft sorting device installed at the end of the conveyor. The heavy objects that are discharged to the outside of the conveyor and collected, and fall through the brush are collected as incombustible materials, and the combustible materials in the heavy objects are collected by the air-injection type air sorter during the fall. To be separated.

In the incline type sorting machine having the above structure, the object to be treated put on the belt conveyor 1 to which vibration is applied by a shaker (not shown) is conveyed by the conveyor. In the process, it is divided into those that roll or slide on the inclined surface (heavy items, light and combustible substances that roll easily) and those that are transported as they are (light and flat items, etc.). Of those that roll or slide on the inclined surface, when reaching the rotary flexible brush curtain 4 arranged in the middle of the inclined surface, lightweight combustible material, combustible material that easily rolls, or incombustible material with a fine particle size, etc. Is conveyed by the belt conveyor 1 without being blocked by the brush curtain 4 and passing through the curtain, and the heavy object pushes and spreads the brush curtain 4 to pass through the curtain and drop downward.

The object to be processed which is conveyed by the belt conveyor 1 without passing through the rotary flexible brush curtain 4 is separated into combustibles and incombustibles by a rotating shaft with a brush sorting device 5 at the end of the belt conveyor. The combustible material is discharged to the outside of the conveyor by the rotating operation of the flexible brush 5-2. Further, incombustibles having a fine particle size, which have been conveyed to the end portion of the belt conveyor, pass through the brush of the rotating shaft sorter 5 with a brush and fall as they are, and the cylinder of the air jet type sorter 6 At the same time as being recovered by the shape recovery hopper 6-2, the combustible material contained in the incombustible material is separated by the air from the blower 6-1 and recovered through the combustible material recovery port 6-4.

[Effect of device]

 In this invention, as described above, a lightweight object (combustible material) such as wood chips and paper passes through the brush curtain together with a heavy object (incombustible material) such as concrete fragments and stones due to the action of the rotary flexible brush curtain. In addition, the rotary shaft sorter with brush and the air jet type wind sorter installed at the end of the belt conveyor separates the object to be processed conveyed on the belt conveyor into combustibles and incombustibles. As a result, it is possible to sort light and heavy objects with high accuracy. Therefore, by making it possible to increase the vibration of the belt conveyor, it is possible to deal with an increase in the number of objects to be processed, and incombustible lumps (concrete pieces, stones, etc.) and combustible materials (wood chips) in industrial waste. It has a great effect on the separation and collection of paper waste, etc.).
