The waste rubber, especially the widely used waste automobile tire, is a recyclable resource which can be reused after being processed. China is not only a large country with rubber consumption, but also a country with relatively deficient rubber resources, however, the reclaimed rubber is just a good supplement to the resources, and is one of the main raw materials necessary for the rubber industry. However, these waste rubber products, including waste tires, are industrial hazardous solid wastes, and the conventional disposal methods for such wastes, such as landfill disposal, incineration and the like, are not suitable for the waste tires. Because the waste tires are made of high polymer materials, the method of filling and burying usually needs hundreds of years to reach the extent of not influencing the growth of plants. If incineration is performed, the carbon monoxide and smoke generated thereby may seriously pollute the environment and may also easily cause fire. Therefore, the development of resource utilization of the waste rubber has considerable economic and environmental benefits.

The current common resource utilization method of waste tires is to crack the waste tires. The tyre is mainly composed of rubber (including natural rubber and synthetic rubber), carbon black and various organic and inorganic auxiliary agents (including plasticizer, anti-aging agent, sulfur, zinc oxide and the like). The thermal cracking of the waste tire rubber powder refers to the process that under the working condition of no oxygen or oxygen deficiency and at a proper temperature, high molecules with unsaturated bonds in the main chain of rubber are broken, products mainly comprise monomers, dimers and fragments, products are polymerized into a plurality of olefins again, volatile substances are removed, and solid carbon is formed, the products mainly comprise pyrolysis oil, carbon black and other storable energy sources, and the components of the products are different along with the changes of a pyrolysis mode, a pyrolysis temperature and the like.

The existing intermittent waste tire rubber oiling equipment has the technical process that waste tires are placed in a reaction kettle, and after the reaction is finished and natural cooling is finished, a furnace door is opened to carry out the next operation. The method has the disadvantages that the cooling time of the reaction kettle is long, the gas in the furnace enters air when the cooling is not thorough, a fire hazard can be caused, a certain amount of smell leaks out when the furnace door is opened, and the health of workers working on the site for a long time is greatly influenced.
