Description

Separating device for pretreatment rubber and iron using wasted tire}

The present invention relates to a separation device for pretreatment of rubber and iron core using waste tires, and more particularly, to collect the waste tires and to grind the waste tires to be crushed to a predetermined size to separate the rubber and iron cores. After the iron core is completely separated, the rubber using the waste tire that is pulverized to improve the separation efficiency of the rubber and the iron core by supplying the crushed waste tire to be recycled by crushing and sorting the rubber separated from the iron core by size. And a separator for iron core pretreatment.

The waste tire crushing apparatus for separating the rubber and iron core after collecting and crushing the waste tires, as disclosed in Korean Patent Laid-Open Publication No. 1998-033677, is a primary crusher for breaking up waste tires into large particles, and primary. Secondary crusher that separates the crushed waste tire pieces into fine particles while separating them into rubber and impurities. It is located and consists of an electronic that removes wires, iron, screws, etc. from the second crushed waste tires.

However, the crusher of such a waste tire is subjected to the first crushing, the second crushing, and proceeds to the process through the cyclone, there was an inconvenience that requires a complex configuration and a large facility area.

As a technique for solving the conventional drawbacks, there is Korean Patent Laid-Open Publication No. 10-2004-0002023, which has a compression plate and a rotating plate and constitutes a pattern plate protruding from the compression plate and the rotating plate, respectively.

However, the conventional continuous shredder has a problem that the parts are broken due to the iron component that is not easily crushed, dust generated during the crushing process is blown to the surroundings and the surroundings are contaminated by harmful substances such as environmental hormones and . There is a problem that the finely broken rubber, etc. between the parts are caught, causing the parts to break and malfunction.

Patent No. 0923287 (2009. 10. 16. registration) relates to a pretreatment apparatus for separating rubber and iron cores from waste tire scrap.

In the pretreatment apparatus for separating rubber and iron cores from the waste tire scrap of the present invention, a scrap supply hopper to which waste tire scrap is supplied is connected to one side, an opening is formed at the bottom thereof, and a grinding space is formed therein. An upper case;

A hopper case communicating with the opening of the upper case is installed on the inner upper side, a discharge port is formed at the lower side of the hopper case, and a dust inflow space is formed at the side and the bottom of the hopper case, so that the dust inflow space and the upper case top Is connected by the connecting pipe, the lower side and one side is open;

A fixing plate having a plurality of fixing pins installed in an inner direction of the upper case in a disk-shaped shape in which a scrap supply hopper is connected to an open center;

The upper case is installed in a direction facing the fixing plate, and a plurality of rotating pins protruding toward the fixing pin is installed, one end of the rotating pin protrudes toward the fixing plate side than the fixing pin end on the side, A rotating plate connected to a motor connected to an externally mounted motor, the rotating plate being spaced apart from the inner wall of the upper case and rotating; It is installed inside the upper case, the outer circumference is provided along the outer periphery of the rotating plate and the fixed plate, the outer circumferential surface with a plurality of separation holes are formed;

One side is connected to the cooling water supply device, the control valve is installed in the middle, the other side is connected to any one selected from the grinding space of the upper case or the scrap supply hopper and the cooling water supply pipe for supplying the cooling water to the grinding space and ;

A screw hopper installed inside the hopper case, the screw hopper configured to discharge the scrap through the opening of the upper case and to be discharged through the outlet of the lower side of the hopper case;

A dust suction device connected to the dust inflow space and the hopper case and configured to suck the dust in the dust inflow space and the hopper case;

It is installed in the form of a bar at a predetermined angular interval toward the periphery of the rotating plate toward the periphery of the rotating plate is installed with the rotating plate to prevent the crushed matter caught in the gap between the back of the rotating plate and the inner wall of the upper case;

However, in the related art, the fixed pins installed on the fixed plate and the rotary pins installed on the rotary plate are pulverized by passing through the holes formed in the separation drum by grinding the supplied tire while rotating, but between the fixed pins. The rotating pin rotates at the blade to grind the waste tires, but the grinding ratio is very low, which leads to a decrease in productivity.The waste tires are not shredded in the separation drum or rotated or kept in place. It is not cut to the size that is discharged, so it blocks the holes that are crushed and discharged so that normal production is not achieved.

In addition, when the tire is filled with waste tires, the grinding efficiency is reduced, or when a breakdown occurs, the door must be opened to repair the interior. However, since it is a heavy product, there is a drawback to call the heavy machinery to open the door. The disadvantage is that the economic and economic consumption increases.

Document 1 Patent Publication No. 1998-033677, published on July 25, 1998 Document 2. Patent Publication No. 1997-0020365, published May 28, 1997 Document 3. Patent registration number 0352281. 2002. 08. 28. Registration Document 4. Patent Registration No. 0923287. October 16, 2009 Registration
