2. Description of the Related Art The most common perforated plates used in a wind separation device include a perforated plate formed by punching a steel plate and a perforated plate made of rubber. Air is blown upward from a hole (a wind selection hole) from a lower portion of the perforated plate, and the processed material flowing down on the perforated plate is sorted by the blown air. That is, the relatively light ones are floated, while the relatively heavy ones are overcome by the wind force to flow down the perforated plate for sorting.

[0003] In the above-mentioned perforated plate, what is close to the size of a wind selection hole or a flat and elongated processed material gets stuck in the hole and causes clogging. There is a problem that the normal sorting is disturbed and the sorting efficiency is reduced, which not only has an adverse effect on the operation but also requires a great deal of labor for removing the clogging. In particular, clogging is likely to occur in the case of a large amount of irregular particles such as waste (usually crushed by a crusher), and the reduction in sorting efficiency is remarkable.

In order to improve the clogging, a bottom plate of a delivery room described in Japanese Utility Model Publication No. 53-32900 has been proposed. This bottom plate is a step-like bottom plate 6 as shown in the right column of page 1 of the publication, lines 15 to 29, and as shown in the drawing, on which a large number of bulging portions 7a are formed. An air supply hole 7b (wind selection hole) is opened in the direction in which the screenings move. Then, air is ejected from a lower portion of the bottom plate 6 through an air supply hole 7b, and a light processed material is levitated by the ejected air and discharged from an upper exhaust port 4b. This makes it possible to prevent clogging of the air supply holes due to screenings, unlike the conventional case where air supply holes perpendicular to the bottom plate are simply formed.

However, in the bottom plate 6, air blown out from the air supply holes 7b is blown obliquely upward with respect to the upper conveying surface of the bottom plate 6, and the air supply holes 7b which blow out such air. Are formed, so that the air blows out toward the outlet side as a whole. for that reason,
A part of the processed product, that is, a light-weight product, flows along the flow of air and flows out to the outlet side, so that a desired product cannot be suctioned accurately, and the reduction in the sorting efficiency cannot be solved.

As described above, since the wind selection holes are provided on the opposed side walls parallel to the flowing direction of the processed material in the concave portions formed on the surface of the plate-shaped main body, the air selection holes are provided at the lower side, for example, the wind box. From the air selection hole into the concave portion, and after the collision and merge in the concave portion, the air can be directly injected at a right angle to the surface direction of the main body. Therefore, even a light-weight treated product is sorted by effectively receiving a floating action from the air without flowing down on the perforated plate.

The perforated plate 1 has a flat main body 10,
The surface of the recess 10 has a recess 12 that is recessed more than the plate thickness of the main body.
Are formed integrally in series in a same direction at predetermined intervals and in a plurality of rows in a staggered manner. As shown in FIG. 3, wind selection holes 13 for blowing air from the wind box 3 to the surface side of the main body 10 are provided on opposing side walls which are the longitudinal sides of the concave portion 12. Opposite side walls on the short side of the concave portion 12 are formed on the inclined wall 14 toward the bottom wall. The inclined wall 14 is provided in order to prevent the light-weight processing object 5a from being caught in the concave portion 12. Then, the perforated plate 1 as described above is attached to the wind separation device 2 such that the longitudinal side of the concave portion 12 is parallel to the flowing direction of the processing object 5 (see the arrow X in FIG. 1).

According to the perforated plate 1, the air inside the wind box 3 is depressed from the opposing wind selection holes 13 as shown in FIG.
The jets are ejected in the same amount in the concave portion 12, and are ejected in the concave portion 12 after the collision and confluence, at an upper portion thereof, that is, substantially perpendicular to the surface direction of the main body 10. Then, due to the jetted air, the processed material 5 flowing down the surface of the main body 10 causes the light-weight object 5b to float largely upward due to the difference in specific gravity. Lightweight object 5
b is blown from the surface of the perforated plate 1 to the outside beyond the partition plate 6, and the non-floating heavy object 5a is dropped directly below the lower end of the surface. In this way, the processing object 5 is sorted into the light-weight object 5b and the heavy-weight object 5a. Wind selection hole 13 as described above
The air blown out from the main body 10 is blown at substantially right angles to the surface direction of the main body 10 and does not blow out toward the downstream or the outlet side unlike the conventional air supply holes. Without being allowed to flow down, the air is effectively subjected to a levitation action from the air to be sorted, and it is possible to eliminate a decrease in the sorting efficiency that could not be conventionally achieved,
The clogging of the wind selection hole 13 is also greatly reduced.

At the time of this sorting operation, the wind selecting hole 13 of the concave portion 12
From the side of the flow of the processing object 5, and the resistance to the flow of the processing object 5 is small, so that it is possible to effectively impart buoyancy to the lightweight object 5 b, and Even if there is no large difference in the specific gravity of, it is possible to reliably sort with high accuracy. Further, since the air selection hole 13 does not hinder the flow of the processing object 5, the processing object 5 smoothly passes through the air selection hole 13 without being caught and clogging. Moreover, the recess 12 has no holes other than the wind selection hole 13, and the side wall formed on the inclined wall 14 without the wind selection hole 13 becomes a part of the guide portion for the workpiece 5 to flow down. Does not cause the clogging of the processing material 5 due to the clogging. Further, since there is no protrusion on the surface of the main body 10, the flow of the processing object 5 is extremely smooth.

According to the first to fourth aspects of the present invention, the air blown out from the wind selection hole can be blown at substantially right angles to the surface direction of the main body because of the above-mentioned structure. Since it does not squirt toward the downstream or outlet side like the pores, even a light-weight treated product is selected by effectively receiving the floating action from the air without flowing down on the perforated plate. It is possible to surely eliminate the reduction in the sorting efficiency that could not be achieved conventionally. In addition, clogging of the wind selection hole can be greatly reduced. In addition, since air can be ejected substantially at a right angle and the buoyancy to the processed object can be accurately directed upward, high-precision and high-efficiency sorting of the processed object can be maintained for a long period of time. Furthermore, since there is no waste in the ejection of air, it is not necessary to supply a large amount of air unnecessarily, so that it is possible to realize downsizing and power reduction of the air supply equipment.
The size of the apparatus using such a perforated plate can be reduced. According to the fifth aspect of the present invention, even when a processed material enters the recess, an effect that the processed material can flow down smoothly can be expected.
