The top of the cooling box 1 is penetrated with an air inlet pipe 2 fixedly connected thereto. The waste tire is converted into gas (oil and water vapor) through the cracking process and injected through the air inlet pipe 2. Due to the different liquefaction points of oil and water vapor, the oil is first liquefied while the water vapor remains as gas, thereby achieving separation of the two. The air inlet pipe 2 is fixedly connected with a spiral condenser 3 connected thereto, thereby increasing the contact area between the gas and the cold water and achieving a good cooling effect. The spiral condenser 3 is fixedly connected with a discharge pipe 4 connected thereto. The discharge pipe 4 penetrates the cooling box 1 and is fixedly connected thereto.

[0025] In the utility model, the motor 12 is started, and the waste tire generates oil and gas (oil and water vapor) through the cracking process. The oil and gas are transported to the spiral condenser 3 through the air inlet pipe 2. The spiral condenser 3 allows the gas to contact with the cold water in the cooling box 1 to cool the gas. The oil is first liquefied, while the water vapor is still gas. The oil is transported to the separation box 5 through the discharge pipe 4. The oil is stored in the separation box 5. The oil is separated through the water outlet pipe 6. The output end of the motor 12 drives the right rotating rod 13, the second belt 16, the rotating rod 17 and the fan 18 to rotate.
