Description

A vertical double-pass waste tire shredder

technical field

The invention relates to a shredding device, in particular to a vertical double-pass waste tire shredder.

Background technique

With the development of the automobile industry, the number of waste tires is increasing, and it is difficult to deal with them. Long-term storage or improper handling will cause serious pollution to the environment. Nowadays, the treatment, recycling and reuse of waste tires have become very urgent environmental and social issues. In the field of waste tire recycling, it is often necessary to shred the existing waste tires before they can be processed and reused.

In order to solve the above problems, Chinese patent (CN203610189U) discloses a cutter body and a shredder. The cutting knife for crushed materials, the hook knife and the cutting knife are installed crosswise, and are evenly distributed on the circumference of the knife body. When the material in the device falls into the crushing cavity, it directly collides with the cutter body, and the impact will shorten the life of the shredder cutter body. In addition, the shape and size of tire fragments obtained when the device shreds waste tires is very different, the particle size is inconsistent, and it is easy to produce sticky rubber fragments, so the shredding efficiency is not high. Similar to this Chinese patent (CN202387528U) discloses a double-shaft shredder of a new type of transmission structure, the device is provided with two horizontal rotating shafts side by side, the cutter bodies are installed on the two horizontal rotating shafts, and the ends of the horizontal rotating shafts are connected with the The star reducer is connected. This equipment has improved the collision between the material and the cutter body to a certain extent, but the problems of inconsistent product particle size and sticking tire fragments have not been solved, and the equipment has a complex structure and high installation accuracy. Chinese patent (CN202539167U) discloses a waste tire recycling device, which utilizes the joint action of a roller press shaft and a milling cutter shaft to crush tires to separate steel wire and rubber in waste tires. The structure of the device is complex, and the milling cutter is used as an executive part, which is easy to wear during the process of shredding waste tires, and the milling cutter is not easy to replace after it is worn out. Similarly, the Chinese patent (CN103963189A) discloses a tire recovery device based on high-pressure water jet crushing waste tires. Power to obtain high enough water pressure to form a water jet to completely crush the rubber; when recycling rubber, it is necessary to separate it from the abrasive in the water jet and dry it. In summary, the existing tire shredding equipment has certain defects both in the product and in the equipment itself.
