  In the wind power sorter as described above, for example, after processing plastic waste mixed with heavy objects such as cans and bottles, waste such as paper containers not mixed with heavy objects may be processed. When intermittently processing waste that does not contain heavy objects in this way, in the conventional wind power sorting apparatus, the heavy material recovery port is closed using a switching damper such as an inclined plate, or wastefully from the air injection port. It was necessary to inject air. When the switching damper is used, it is necessary to retreat the switching damper to a place where there is no hindrance to sorting when processing waste mixed with heavy objects again. For this reason, in order to secure the retreat place of a change damper, there is a problem that a wind power sorter enlarges or consumes useless energy for operation.

  Therefore, an object of the present invention is to provide a wind power sorting apparatus that is compact and does not consume wasteful energy even when a processed material that is not mixed with heavy objects is processed intermittently.

  In order to solve the above-described problems, the present invention provides air from the side between a processing material inlet provided at the top of a casing and a plurality of recovery ports provided at a bottom of the casing. In the wind power sorter that provides an air jet for jetting, and sorts and collects the processed material falling from the inlet by the wind of the air jetted from the air jet, the air jet A rotating plate that can be rotated around a horizontal axis is provided in front of the opening, and when the rotating plate is used to inject air from the air injection port, the processed product drops the injected air from the input port. When it is rotated toward the air injection port so that the air is not injected from the air injection port, the processed material falling from the charging port is directed toward the recovery port so as to guide it to a predetermined recovery port. Adopted a configuration to rotate diagonally downward.

  That is, a rotating plate that can be rotated around a horizontal axis is provided in front of the air injection port, and when air is injected from the air injection port to this rotating plate, the injected air falls from the input port. When it is rotated toward the air injection port so as to be guided to the processed material and air is not injected from the air injection port, the processed material falling from the charging port is directed toward this recovery port so as to be guided to the predetermined recovery port. By turning diagonally downward, it is possible to intermittently process a processed material that is not mixed with a heavy object without using wasteful energy with a compact design.

  The wind power sorting apparatus according to the present invention is provided with a rotating plate that is rotatable around a horizontal axis in front of an air injection port, and when air is injected from the air injection port to the rotating plate, the air to be injected Rotate toward the air injection port so as to guide the processed material falling from the input port, and when not injecting air from the air injection port, so that the processed material falling from the input port is guided to a predetermined recovery port, Since it is made to rotate obliquely downward toward the recovery port, it is possible to intermittently process a processed material that does not contain heavy objects without consuming unnecessary energy. Further, the rotating plate has both a function as a current plate for the air jetted from the air jetting port and a function as a chute for guiding the fallen processed material to a predetermined recovery port, so that the apparatus can be miniaturized. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, this wind power sorting apparatus is provided with an insertion port 3 into which a discharge end of a belt conveyor 2 that supplies waste to be sorted is inserted at an upper portion of a side wall 1 a of a casing 1. Two recovery ports 4a and 4b branched at the bottom are provided. An air chamber 5 to which air is supplied is provided on the outer side wall 1 a on the lower side of the inlet 3, and a nozzle 6 for injecting air obliquely upward to waste falling from the discharge end of the belt conveyor 2 is provided in the air chamber 5. A rotating plate 7 to be described later is provided in the casing 1 diagonally above and forward of the nozzle 6.

  Further, an exhaust port 8 for discharging the injected air together with dust is provided at the top of the casing 1, and a regulating plate 9 for restricting the downward flow of the air is attached below the exhaust port 8. It has been. Furthermore, an upward branch plate 10 that can be tilted and expanded and contracted is provided at a branch portion between the collection ports 4a and 4b, and a rotating roller 11 is attached along the tip thereof.

  As shown in FIGS. 2A and 2B, the upper nozzle 6 is flat and the tip side is bent obliquely upward, and the shaft portion 6a provided on both sides of the casing 6 is formed by the U band 12 with the U band 12. A pair of suspension portions 6b that are pivotably attached to the side wall 1a and provided on the upper surface are fixed at a predetermined rotation position by suspension brackets 13 that penetrate the top plate of the air chamber 5, and the tip of the nozzle 6 is It is inserted into the casing 1 through a slit 14 provided in the side wall 1a. Although not shown, the lower-side nozzle 6 is also formed in the same form, and a pair of support portions are provided on the bottom surface instead of the suspension portion 6b on the top surface, and the support bracket that penetrates the bottom plate of the air chamber 5 The only difference is that it is fixed at a predetermined rotational position.

  As shown in FIGS. 3A and 3B, the rotating plate 7 has a slide plate 7c attached to a substrate 7b attached to a horizontal rotating shaft 7a. It can be stretched. The rotating shaft 7a is passed through the side wall 1a in the width direction of the casing 1, and both ends are rotatably supported by bearings 15, and hydraulic pressure is applied via a lever 16 attached to one end of the rotating shaft 7a. The cylinder 17 is rotated. The slide plate 7c is provided with a long hole 18 at both ends, and the slide position can be adjusted by changing the locking position of the long hole 18 and the bolt 19 to the substrate 7b.

  When processing the waste mixed with heavy objects in the wind sorting apparatus described above, the rotating plate 7 is rotated in the vertical plane toward the nozzle 6 as shown by the solid line in FIG. Among the waste that falls from the discharge end of the belt conveyor 2 by the wind force of the jet air guided from the nozzle 6 guided along the rotating plate 7, a lightweight material such as plastic or paper is collected in the far-side collection port 4b. Then, heavy objects such as cans and bottles fall as they are and are collected in the collection port 4a directly below. At this time, the amount of tilt and the amount of expansion / contraction of the branching plate 10 of the branching portion can be adjusted so that the branching point of the heavy object and the light object is in an optimal state. Further, the rotating roller 11 is driven to rotate in the clockwise direction, and drops a plastic sheet or the like caught on the tip of the branch plate 10 to the collection port 4b for the lightweight material.

  On the other hand, when processing waste such as paper containers that are not mixed with heavy objects, the supply of air to the air chamber 5 is stopped and the injection of air from the nozzle 6 is stopped. As indicated by the dotted line, the rotating plate 7 is rotated obliquely downward toward the light collection port 4b, and all the waste is collected in the collecting port 4b using the rotating plate 7 as a chute. At this time, the rotation plate 7 can adjust the amount of expansion and contraction toward the tip side by changing the slide position of the slide plate 7c so that a part of the waste does not fall into the heavy material collection port 4a. The sliding position of the sliding plate 7c is not changed, and the branching plate 10 may be tilted below the rotating plate 7 as shown by a two-dot chain line in FIG. .
