Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for waste materials such as home electric appliances, and more particularly to a crusher for household appliances such as metal and non-metals such as plastics for easy separation and recovery. The present invention relates to a crusher that crushes waste into fine powder.

[0002]

2. Description of the Related Art Conventionally, wastes of home electric appliances such as televisions, refrigerators, washing machines, or wastes of office automation equipment such as copy machines and personal computers have been crushed by a crusher and then treated with metal and plastic materials. It is supposed to be separated and collected into non-metals.

By the way, as a crusher for crushing the wastes of home electric appliances and OA equipment, a required number of rotating shafts are inserted through bearings in a casing having an inlet and an outlet at the upper and lower portions. It is known that the rotary shafts are rotatably provided in parallel and each of the rotary shafts has a disk-shaped crushing blade with hooks alternately arranged around the rotary shaft so that the crushing blades can be freely aligned with each other (Japanese Utility Model Publication No. 57-13174). Gazette, Japanese Utility Model Publication No. 62-136232, etc.).

The crusher constructed as described above is
While rotating the respective rotary shafts inwardly, the waste is thrown into the casing through the charging port at the upper part, and is sequentially drawn into the gap between the crushing blades by the hooks for shear crushing. Then, the crushed waste is supposed to be separated by a required sorter such as a magnetic sorter into metal and non-metal such as plastic and collected.

[0005]

However, since the above-mentioned crusher is one in which disk-shaped crushing blades with hooks are alternately fitted to perform shear crushing, it is inevitable that wastes such as home electric appliances are 50 mm to 150 mm. And it can only be crushed into relatively large chips. For this reason, it is very difficult to separate and collect metals and non-metals such as plastics from crushed pieces of waste, let alone household electric appliances and OA equipment in recent years. This is even more difficult because there are many cases in which the two are integrally formed. In addition, in order to grind a crushing blade that is worn or has foreign matter attached, the crushing blade must be removed and polished, which is very troublesome and time-consuming.

The present invention solves the problems of the conventional example,
Wastes such as home electric appliances are crushed into fine powder,
Let's provide a crusher for waste such as home appliances that not only facilitates separation and collection of metals and non-metals such as plastics, but also can easily grind crushing blades as needed. It is what

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below based on an embodiment shown in the drawings. 1 and 2 show an embodiment of the present invention, in which 1 is a rectangular casing having a required width and height installed on a frame (not shown), 2 Is a charging port formed on the upper part of the casing 1, 3 is a hopper disposed above the charging port 2,
4 is an outlet formed in the lower part of the casing 1 and 5 is a casing.
A rotor 6 having a required length and an outer diameter, which is rotatably horizontally arranged in the sing 1, has a projection formed integrally along the longitudinal direction of the rotor 5 on the outer peripheral surface thereof at a predetermined pitch. It is a crushing blade. Although not shown, the rotor 5 is connected to the motor through a required winding transmission mechanism so as to rotate inward in the direction shown by the arrow in FIG. Reference numeral 7 denotes a grindstone roll of the same diameter and length which is rotatably arranged side by side on the rotor 5 at the same level. , 9 are a pair of upper and lower guide rails each having a required length, which are mounted on both sides of the casing 1 so as to guide the mounting plate 8 slidably in the direction of the rotor 5. The roller 7 is set to be freely contactable with and separable from the rotor 5 by appropriately sliding the mounting plates 8 on both sides along a guide rail 9 in a predetermined direction. Although not shown,
The grindstone roll 7 is connected to the motor through a required winding transmission mechanism so as to rotate outward in the direction shown by the arrow in FIG. 2, and rotates at a higher speed than the rotor 5. It is supposed to be.

Next, the operation of the embodiment configured as described above will be described. First, attach the mounting plate 8 to the guide rail 9
The grindstone roll 7 is brought closer to the rotor 5 by appropriately sliding along the above, and is set in parallel with a predetermined gap. After that, while rotating the rotor 5 inward at a low speed and rotating the grindstone roll 7 outward at a high speed, waste such as home electric appliances and OA equipment is discharged from the hopper-3 through the inlet 2. Throw in. At this time
Such waste is not put in its original form, but is put into pieces of waste that have been previously crushed into chips of 30 to 150 mm by a conventional crusher or the like. Then, the waste piece is pinched from both sides by the crushing blade 6 of the rotor 5 which rotates inwardly and the outer peripheral surface of the grindstone roller 7 which rotates outwardly, and crushes the waste piece while crushing it to 1-2 mm. It is pulverized into fine powder to separate the metal and non-metal attached. At this time
Since the grindstone roller 7 is rotated outwardly at a high speed with respect to the rotor 5 which is rotated inward, the waste pieces can be crushed and ground simultaneously without load, quickly and reliably. It can be crushed. The waste pulverized into fine powder may be discharged downward through the discharge port 4, and then separated into metal and non-metal by a known magnetic separator or the like.

Further, in the above embodiment, not only the waste pieces can be pulverized into powder as described above, but also the crushing blade 6 of the rotor 5 can be polished as required. . That is, when grinding the crushing blade 6 of the rotor 5, the mounting plate 8 is slid along the guide rail 9 so that the grindstone roll 7 is pressed against the crushing blade 6 of the rotor 5. After that, the grindstone roll 7 is rotated outward, and the rotor 5 is rotated inward.
The grinding wheel roll 7 is used to polish the crushing blade 6.

Although the crushing blade 6 is formed integrally with the rotor 5 in the above embodiment, the crushing blade 6 is not limited to this, and the crushing blade 6 can be attached and detached with a required mounting member. It may be configured to be attached to. Further, the grindstone roll 7 is supposed to rotate at a higher speed than the rotor 5, but it may be rotated at a constant speed. Further, the grindstone roll 7 can be brought into and out of contact with the rotor 5 by sliding the mounting plate 8 along the guide rail 9, but the grindstone roll 7 is not limited to this, and it is not limited to this. It may be configured to be brought into contact with and separated from the movable means of.
