Description

[Detailed description of the invention] This invention relates to a device for sorting out metal scraps contained in crushed wastes such as scrapped cars, household appliances, and empty cans that are crushed using an appropriate crusher. .

Conventionally, if the metal in the crushed material is iron, it can be separated using a magnet, but valuable materials made of non-ferrous metals such as aluminum or copper cannot be separated. Furthermore, even in the case of iron, those that are not separated by a magnet and are removed often mix with other garbage, resulting in wasted resources.

This invention aims to solve the above-mentioned problems, and uses the difference in specific gravity between centrifugal force and airflow to perform sorting. That is, this invention provides a vertical rotary cylinder driven by an appropriate driving means in a cylindrical body having an outlet at the bottom and an input port at the center of the upper part.
A tapered receiving plate whose upper part is enlarged to form an opening is integrally installed at the upper end of this rotary cylinder, and the opening center of this receiving plate is used to store waste including metal scraps inputted from the input port into the receiving plate. By providing a cone-shaped dispersion plate that disperses the air in
Due to the centrifugal force of the crushed materials rotating with the rotating tapered receiving plate and the blowing up action of the air current, paper, plastic, cloth, etc. with light specific gravity are ejected out of the receiving plate, and comparatively heavy materials such as iron, aluminum, copper, etc. Heavy, hard objects are designed to be dropped into the rotating cylinder.

The details of the sorting device of this invention will be explained below based on an embodiment shown in the accompanying drawings.

In the figure, reference numeral 1 denotes a main body consisting of a cylindrical peripheral wall 2 and a funnel-shaped bottom 3, which has a discharge tube 4 on one side of the bottom and a vertical receiving tube 5 in the center of the bottom.

The upper end of the main body 1 is open, and the input port 6 faces the center of the upper part.

Reference numeral 7 denotes a rotating cylinder which is rotatably fitted into the receiver cylinder 5 and has a V-pulley 8 fixed to its lower outer periphery, and is driven at a predetermined speed by driving means such as a motor 9 and a V-belt 10.

A circular tapered receiving plate 11 with an open top is integrally fixed to the upper end of the rotary cylinder 7, and a cone-shaped dispersion plate 12 is fixed to the center of the upper opening. In the illustrated example, the dispersion plate 12 is supported at the upper center of the receiving plate 11 by a plurality of arms 13 fixed to the upper end of the receiving plate 11.
may be supported.

Reference numeral 14 designates a plurality of air supply pipes passing through the rotary cylinder 7, and a plurality of jet ports 15 at the upper ends of the pipes blow air up from the inner lower part of the receiving plate 11 along the inner surface of the receiving plate 11.

The sorting device of this invention has the above-mentioned configuration, in which the rotary cylinder 7 is rotated at a predetermined speed, airflow is ejected from each jet port 15, and garbage such as crushed materials including metal scraps is dispersed from the input port 6. Board 12
Throw it on top.

The thrown garbage is dispersed around the surrounding area by the dispersion plate 12 as shown in the figure, and evenly distributed on the receiving plate 11, but these garbage rotate together with the receiving plate 11.

If the rotation speed of the receiving plate 11 is increased too much, heavy materials such as iron and copper contained in the dust will fly out from the upper edge of the receiving plate 11 due to centrifugal force. Keep the rotation below a certain level.

However, due to the airflow blowing upward from each spout 15, light paper, cloth, plastic, etc. are blown up and over the upper edge of the receiving plate 11, causing
It falls through the main body 1, passes through the discharge pipe 4, and is discharged.

Also, iron, which is heavier than paper, cloth, plastic, etc.
Metals such as copper and aluminum slide down inside the receiving plate 11, pass through the rotating cylinder 7 as shown in b, and are collected from the lower end thereof.

As mentioned above, the sorting device of this invention uses a cone to distribute the garbage and throw it into the rotating tapered receiving plate, so that all the garbage is evenly distributed on the receiving plate. It comes into contact with the airflow that blows up along the inside of the receiving plate, and all of the items with light specific gravity are blown up. In addition, since items with heavy specific gravity fall into the rotating cylinder without being blown away by the air current, valuable materials such as iron, copper, and aluminum that could not be sorted by magnetic sorting can be efficiently recovered.
