Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting-type crusher, and more particularly to a cutting-type crusher capable of finely crushing heat-pressed composite waste materials of home appliances and automobiles.

[0002]

2. Description of the Related Art In recent years, many products, such as home appliances and electronic devices, are made of plastics and composite materials with various metals. Is difficult and difficult to process, which is a major social problem. As a current treatment method, a method in which a product is manually decomposed and then valuables such as metals are collected is used. However, this method has limited processing capacity and profitability because most of the separation and collection work is performed manually, and is limited to products containing a large amount of metals such as automobiles. On the other hand, products such as home appliances and electronic devices, in which plastics account for a large proportion of the entire product and have a small amount of valuables such as metals, are rarely collected and discarded. . At present, the usual waste disposal method involves crushing waste with a crusher. In such a case, since the crushed pieces of plastics are mixed into valuable resources in large quantities, the recovery of valuable resources Causing difficulties. As a simple method for treating such a large amount of waste such as home electric appliances and electronic devices, the present inventors first divide these composite material wastes into oxygen-free or low-oxygen high-temperature. It has been proposed to separate and recover metals after heat treatment in an atmosphere. According to this method, waste materials that have been heat-treated and gasified to remove plastic components are pressed and finely crushed. However, in the conventional crusher, there is a problem that if there is a different kind of metal, a “wrapping phenomenon” occurs at the time of crushing, and it becomes difficult to separate the metal in the subsequent processing.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, and solves the problem of encapsulating a dissimilar metal lump obtained by heat-treating and pressing composite material waste such as home appliances and automobiles.
It is an object to provide a cutting type crusher capable of fine crushing.

[0004]

In order to solve the above-mentioned problems, the present invention provides a workpiece holder fixed to a base and a cutting surface arranged opposite to the workpiece holder. A cutting body provided with a cutting blade, and a rotating shaft connected to a cutting surface other than the cutting surface of the cutting body (preferably the opposite surface) to rotate the cutting body;
A motor connected to the rotating shaft to rotate the rotating shaft, a vertically movable frame holding the cutting body or the motor,
A cutting die comprising: an elevator for raising and lowering the frame; and a guide mechanism having a guide plate for moving a workpiece to a predetermined position on a workpiece holder and guiding cutting chips to the outside of the apparatus. It is a crusher. Further, according to the present invention, a cutting body having a cutting blade fixed to a base portion on an upper surface, and a workpiece holding member disposed to face the upper surface of the cutting body and having a workpiece holding surface on the facing surface A body, a rotating shaft connected to the other side of the workpiece holding surface of the workpiece holder (preferably the opposite surface) and rotating the workpiece holder, and a rotating shaft connected to the rotating shaft and rotating the rotating shaft. A motor, a vertically movable frame that holds the workpiece holder or the motor, an elevator that raises and lowers the frame, and a workpiece that is moved to a predetermined position below the workpiece holder to remove cutting chips. And a guide mechanism provided with a guide plate capable of guiding the workpiece to the outside of the apparatus and fixing the workpiece as needed. In the cutting type crusher, the workpiece holding surface of the workpiece holder has a projection or a groove, or can be an electromagnet, and holds the workpiece by a guide plate provided in a guide mechanism. It can also be fixed to a surface. The cutting blades are randomly arranged on the cutting surface of the cutting body, and large and small cutting blades can be randomly arranged in a radial or spiral shape on the cutting surface of the cutting body.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Heat-treated products such as home appliances and automobiles are easily disassembled and separated when plastics or other easily decomposable parts are used for assembly screws and bolts. In many cases, dissimilar metals are intricately entangled and difficult to decompose. Preferably, these dissimilar metals are desirably compressed by scrap pressing in order to facilitate cutting, and then finely pulverized. The cutting-type crusher of the present invention, the metal for example 0.1%
It is possible to separate and collect metals by cutting and pulverizing to a size of from 10 mm to 10 mm or less to eliminate the “wrapping phenomenon”. The size of the fragments can be selected according to the size of the blade of the cutter (cutting body) to be used and the feed speed of the cutter. The shape of the cutting body provided with the cutting blade is a disk shape, a cylindrical shape, a flat plate shape or a rod shape, and the flat surface or the cylindrical surface of the cutting body is made of cemented carbide, ceramics or tool steel, for example, having a height of 3 to 10mm, width 5-30mm, depth 5-1
One or a plurality of blades having 0 mm and a tip angle of 60 to 90 degrees are randomly or radially or spirally mounted.

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a front sectional view showing an example of a cutting-type crusher of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG.
FIG. In the drawing, 1 is a base, 2 is a workpiece holder having a workpiece holding surface 3, and 4 is a cutting blade 5.
A rotating body for rotating the cutting body 4;
Is a motor for rotating the rotating shaft 6, 8 is a vertically movable frame holding the cutting body 4 and the rotating shaft 6 and the motor, 9 is an elevator for vertically moving the frame 8, and 10 is the workpiece 1
1 and a guide mechanism for moving a guide plate 12 for guiding cutting chips to the outside of the apparatus to a predetermined position on the workpiece holder 2. 13 is a chute for cutting chips.

The cutting type crusher shown in FIG. 1 operates as follows. A block (cut object 11) made of pressed metal or the like is inserted between the cut body 4 and the cut object holder 2, and the cut object 11 is placed on the cut object holding surface 3 of the cut object holder 2. It is fixed by the formed protrusion or groove or the electromagnet and the guide plate 12. Next, by operating the elevator 9 to move down the frame 8 and operate the motor, the cutting body 4 is moved.
Is rotated, and the block 11 fixed to the holding surface 3 of the workpiece holder 2 is finely pulverized into fragments of, for example, 0.1 to 10 mm by the cutting blade 5 on the cutting body 4. The finely crushed fragments are blown away by rotation, and the guide plates 12 provided on the left and right are provided.
Is discharged from the chute 13 for cutting chips. FIG.
Then, an elevator 9 for raising and lowering the frame 8 and a guide mechanism 10
Is performed by a hydraulic cylinder. Further, although the cutting body is rotating, the cutting body may be replaced with the workpiece holder, and the workpiece holder may be rotated to fix the cutting body.

[0008]

According to the present invention, when finely pulverizing composite materials such as dissimilar metals, it is possible to eliminate the "envelopment phenomenon" and to finely crush each single material. When heat-treated and pressed for treatment, valuable resources can be effectively separated and collected.
