Description

Waste tire cutting device {A cutting apparatus for used tires}

The present invention relates to a waste tire cutting device, and more particularly, to reduce the volume and weight of the waste tire by automatically dividing and cutting the waste tire while minimizing the labor input of a worker, thereby increasing the space utilization during transportation or loading of the waste tire, and the waste tire It relates to a waste tire cutting device that improves incineration efficiency even during incineration.

In general, a tire mounted on a wheel of an automobile should be replaced with a new tire because the circumferential surface thereof is worn and the braking force is reduced as the tire is used for a certain period of time. In Korea, more than 10 million of these waste tires are currently generated, but due to the rapid increase in automobiles, the number of discarded tires is greatly increasing.

In storing waste tires whose service life has expired, as the tires are stored in their original form, the loading space is occupied more than necessary, and the risk of overturning exists due to the stacking of heavy tires in order to load a large amount. However, when transporting tires, it is difficult to efficiently use the transport and loading space due to the circular tires, which increases the transport cost and requires a lot of labor due to loading and unloading the tires.

In addition, if large waste tires are incinerated in their original form, it is difficult to completely burn them due to low combustion efficiency, making it difficult to use waste tires as kindling for incinerating other wastes in incineration facilities, and reducing pollutants or dust caused by incomplete combustion of waste tires. For this purpose, there is a problem in that the capacity of the dust collector or purification device must be increased.

In order to recycle such waste tires, research on recycling them by crushing them into a certain size has been actively conducted for several years.

Most conventionally proposed waste tire shredders are equipped with a hopper for receiving waste tires, a rotary cutter installed in the lower region of the hopper, and a transfer conveyor for transporting the pulverized material by the rotary cutter. When the tires are supplied, the waste tires are cut into pulverized pieces of small particles by the rotary cutter and discharged to the outside by the transfer conveyor.

However, the conventional waste tire crusher cools the waste tire in a brittle state in order to remove the steel wire included in the waste tire, and then cuts the waste tire using a device separately equipped with two crushers that appear to be a die and a punch. and crushing process, there is a problem of low efficiency and economic feasibility because large-capacity waste tires cannot be crushed in a short time, and the conventional waste tire crusher as described above generates a large amount of dust during the crushing process, resulting in pollutants There is a problem that causes

Most conventional cutting equipment that cuts waste tires instead of crushing them uses a grinder or cutting shears to cut them manually, so the tire cutting process is inefficient and the iron core in the tire protrudes during the work process, causing workers to There is a great risk of getting injured. In addition, it is very difficult for workers to carry or cut large tires such as buses or trucks, and thus, it is very difficult to cut the large tires.
