Description

Spiral auger with self-cleaning function in waste rubber cracking

Technical Field

The utility model relates to a machine-building equipment technical field, concretely relates to spiral auger that has self-cleaning function in the pyrolysis of rubber waste.

Background

Rubber is the fourth rough resource following industrial raw materials such as petroleum, iron ore, nonferrous metals and the like, along with the rapid increase of the usage amount of automobiles, the stock of domestic waste tires and various waste rubber products is more and more, and according to incomplete statistics, only the waste tires in China are gradually increased at the speed of about 15 percent per year. The waste tires are piled in the open air for a long time, not only occupies a large amount of land, but also is easy to breed mosquitoes to spread diseases and is easy to cause fire. The "black contamination" caused by the scrap tires has been a very serious problem. At present, the annual recovery rate of the waste tire rubber in China is about 47 percent, which belongs to a medium and low level, wherein the recovery rate of the waste tire is about 60 percent. The waste tire recycling industry has been listed by the nation as a key development field of recycling economy. With the rapid development of automobile industry in China, the automobile keeping quantity is increased year by year, and the waste tires are correspondingly and rapidly increased. The automobile keeping quantity of China is estimated to reach 3.5 hundred million by 2020. The accumulation of a large amount of waste tires is easy to breed mosquitoes and can cause fire disasters, thereby bringing serious harm to human environment. In China, natural rubber and petroleum resources are seriously lacked, so that the problem of rubber resource shortage by partially replacing raw rubber with regenerated rubber produced by waste rubber in China becomes an important means, and the regenerated rubber becomes the third largest rubber resource beyond natural rubber and synthetic rubber. However, the black pollution of the waste tires cannot be completely eliminated by the means for a long time, and the waste tire disposal and resource utilization technology is a worldwide problem of environmental protection. The research and development of the technology of complete recovery and high added economic value are devoted all the time at home and abroad, and the technology of thermal cracking of waste rubber is quietly moved to the industrial development stage by the specific advantages of the technology. The method has great significance in solving the problem of recycling and reusing the waste tires, eradicating secondary pollution, relieving energy crisis, eliminating pollution, realizing resource recycling and the like.

Patent No. CN201821568587.6 entitled: a sludge/waste rubber harmless treatment system and a continuous separation device thereof, and discloses a waste rubber pyrolysis technology.
