Due to the rapid industrialization and urbanization tendency of modern society, various industrial products made of various materials are being mass produced, and various industrial wastes resulting from the disposal of these industrial products are also generated in large quantities.

When these industrial wastes are left in the yard for a long time or incinerated, the environment is seriously polluted due to the discharge of pollutants, and the recyclable resources contained in these wastes are discarded as they are.

Accordingly, researches for active recycling of waste resources discharged from these industrial wastes have been actively conducted recently, and a representative example thereof is a technique of grinding waste tires and recycling them as sidewalk blocks or building materials.

Korean Patent Registration No. 10-1013576 discloses a "pulverizer for waste tires" as a waste tire crusher for crushing waste tire pieces sliced into chip shapes to a desired particle size. In the waste tire crusher, a rotary blade is used in which a blade is linearly formed along the longitudinal direction of a rotary shaft. In the case of a waste tire, since the rubber material has elasticity, There is a problem that it is very difficult to uniformly crush the waste tire chip to a desired particle size because the waste tire chip is easily compressed or repelled.

In addition, when the waste tire is crushed, heat is naturally generated in the rubber, and thermal deformation of the material such as the blade, the shaft, and the fixed frame occurs due to the heat, thereby causing excessive maintenance and repair costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pulverizing apparatus for a waste tire according to the present invention will be described in detail with reference to the accompanying drawings.

In the description of the present invention, the term "waste tire" refers to a piece of waste tire that has been broken up into a large piece by separating the iron core from the iron-core separator. The waste tire crushing device refers to a waste tire crushing device, In the form of powder).

1 and 2, a waste tire crushing apparatus according to the present invention is formed with a hopper-shaped inlet 10 having an open top so that a waste tire can be injected thereinto, A pipe 20 is provided in the horizontal direction and a conveying screw 21 which is rotatably received by receiving a rotational force from an external power source (for example, a driving motor, M) is inserted into the inlet. The transfer screw injects the charged waste tire between the fixed disk 30 and the rotary disk 40 to be described later.

A fixed disk 30, which is fixed to the end of the charging tube 20 so as to protrude in the outward direction and has a plurality of fixed blades 31 disposed at the rear edge thereof, is disposed coaxially with the fixed disk, A rotary disk 40 provided with a plurality of corresponding crushing blades 41 is disposed.

The fixed disk 30 is formed to have a predetermined thickness, and a through hole is formed at a central portion of the fixed disk 30 so as to communicate with the feed screw and to discharge the transported waste tire. The shape of the fixed blade 31 is not limited to the right range of the present invention. For example, as shown in FIG. 5, a blade having a sharp-edged rectangular shape can be used.

The rotation disc 40 is formed to have a predetermined thickness and a through hole is formed at a central portion thereof so that air discharged from the discharge pipe 110 provided inside the rotary shaft 50 can be introduced. The shape of the crushing blade 41 is not limited to the right range of the present invention. For example, a blade having a rectangular shape with sharp edges as shown in FIG. 6 may be used.

The fixed blade 31 and the crushing blade 41 are provided in a plurality of identical numbers and when the fixed disk 30 and the rotary disk 40 are opposed to each other, the fixed blade and the crushing blade are coupled to correspond to each other . The fixed blade 31 and the crushing blade 41 may be separately coupled to the fixed disk and the rotating disk so that only the worn blade of the plurality of blades can be selectively replaced.

The fixed disc 30 and the rotating disc 40 are further protruded outward than the center portion of the edge. When the fixed disk 30 and the rotating disk 40 are spaced apart from each other by a predetermined distance, a predetermined space is formed at the center of both the disks so that the waste tire inserted through the transport screw 21 is located inside the space.

A rotary shaft (50) protrudes rearward from the center of the rear surface of the rotary disk (40).

The rotating shaft 50 is fixed through a fixed frame 60 of the inner bearing therein, and is rotated by an external power drive 70 which is rotated by a rotating force generated by (for example a drive motor). In the embodiment of the present invention, as shown in FIG. 2, a pulley is coupled to an end of the rotary shaft 50, a pulley is coupled to a driving shaft of a driving motor provided at a side of the rotary shaft, and a belt is connected to transmit power.

When the waste tire is charged through the charging port 10, the transfer screw 21 transfers the waste tire along the inside of the charging pipe 20 so that the fixed disk 30 and the rotating disk 40 are close to each other And then into the space formed therebetween. Thereafter, when the rotating disk 40 rotates, the waste tire, which was located in the space, moves to the edge side by the centrifugal force and is naturally drawn between the fixed blade 31 and the crushing blade 41 and is crushed and discharged to the lower portion.

In the meantime, if the size (width) of the waste tire inserted into the space formed between the fixed disk 30 and the rotary disk 40 is larger than the interval between the fixed disk 30 and the rotary disk 40, Can not be. In other words, the waste tires injected into the space can be discharged to the outside only after being crushed, and this principle is similar to that of the millet, which is configured so that the input grain is discharged after being crushed between the upper and lower marbles.

Since the waste tires have elasticity due to the nature of the rubber material, it is difficult to uniformly crush the waste tire chips into a desired particle size because the waste tire chips are easily compressed or repelled when the straight tire is cut in a direction perpendicular to the fixed blade.

When the rotary disk 40 is rotated with the fixed disk 30 and the rotary disk 40 facing each other according to the present invention, the waste tire is moved to the space between the fixed blade 31 and the grinding blade 41 by centrifugal force When the rotating disk 40 is rotated, the fixed blade 31 and the grinding blade 41 intersect with each other to cut the waste tire to a desired size (gap between the fixed disk and the rotating disk) while pressing the waste tire. When the force of the crushing blade 41 is applied to the waste tire, the fixed blade 31 supports the waste tire while applying the same force to the waste tire, thereby achieving smooth cutting.

In the waste tire crushing apparatus according to the present invention, the fixed blade 31 and the crushing blade 41 are provided in a plurality so that the fixed blade 31 and the crushing blade 41 continuously cross each other when the rotating disk is rotated , There is an advantage that a considerably large amount of waste tires can be treated (pulverized) when compared with conventional waste tire crushers.

3, the supporting frame 80 is coupled to the inlet port 10, the inlet pipe 20 and the fixed disk 30 so that the inlet pipe 20 and the fixed disk 30 are integrally coupled to each other, and the support frame is slid forward or backward And a distance adjusting means 100 for adjusting the distance to be moved.

The guide part 90 is slidable along the longitudinal direction on the shelf 91 to be mounted, and is provided on the bottom surface of the support frame to support the support frame. The guide portion is formed with a guide hole (not shown) in which a thread is formed on the inner peripheral surface along the longitudinal direction.

The distance adjusting means 100 includes a distance adjusting frame 101 having a predetermined length formed with threads on the outer circumferential surface so as to be inserted into the guide hole and a handle 102 for rotating the distance adjusting frame clockwise or counterclockwise, .

When the handle 102 is rotated, the distance between the fixed disk 30 and the rotary disk 40 can be adjusted by pulling or pushing the support frame 80 while the distance adjusting frame 101 rotates, It is possible to crush the waste tire into a chip shape having a desired size. If the fixed blade 31 and the crushing blade 41 are completely in contact with each other, rotation of the rotary disk can not be performed. If the fixed blade 31 and the crushing blade 41 are separated from each other too much, the waste tire can not stay in the space and falls down to the floor. It is preferable to appropriately adjust the distance between the disk and the rotating disk.

Next, referring to FIG. 4, the discharge tube 110 is provided inside the rotary shaft 50 to blow air into a space between the fixed disk and the rotary disk.

The reason why the air is blown through the discharge pipe 110 is that the waste tire, which is additionally introduced through the feed screw 21 during the pulverization of the waste tire, flows into the space between the fixed blade 31 and the pulverizing blade 41, So that the work can be performed. In addition, since the fixed blade 31 and the crush blade 41 continuously friction during the crushing process, the temperature rises due to the frictional heat, so that a considerable temperature reduction effect can be expected by blowing air through the discharge pipe . For example, when the temperature of the fixed blade (or the crushing blade) rises during the crushing process, there is a problem that the waste tire is crushed and rubber adheres to the surface of the blade to reduce the cutting force. Therefore, 31 and the crushing blade 41 are prevented from rising.

In addition, the other end of the discharge pipe 110 is branched, and one side is formed as an air inflow pipe 111 through which air flows. The other side is formed by the fixed blade 31 or the grinding blade 41 is formed of a water inflow pipe 112 into which water is introduced so as to prevent the temperature of the water from rising. The water introduced through the water inflow pipe 112 cools the inside of the space like the cooling water of the automobile, lowers the temperature of the fixed blade and the crushing blade, and serves as a washing water for washing away foreign matter remaining after crushing the waste tire .

According to the present invention as described above, since a waste tire is guided between the fixed disk and the rotary disk provided with a blade and is sequentially cut, it is possible to prevent the waste tire from being compressed or repelled during cutting, It is possible to easily grind the waste tire to a desired size by adjusting the distance of the disk.
