Equipment for preheating and cracking waste tires on basis of solar energy

The invention discloses equipment for preheating and cracking waste tires on the basis of solar energy. The equipment comprises a heat collecting device, a feeding preheating device, a cracking device, an oil-gas separation storage device, a solid product recovery device and an automatic control system. The devices are connected with one another, and the heat collecting device in the equipment forpreheating and cracking waste tires on the basis of solar energy can absorb solar energy to provide necessary temperature for cracking the waste tires; a disc type heat collector in the heat collecting device can collect sunlight. According to the equipment, the defects of strong dependence of traditional pyrolysis modes on fossil fuels or electricity and insufficient heat supply, caused by the factors such as weather and different time periods, of sunlight in the prior art are overcome, the economic benefit is increased, and carbon emission is reduced. An automatic tracking device of the disc type heat collector can
