Description

Technical Field

[0001] This utility model relates to the field of pyrolysis device technology, specifically a pyrolysis device for processing waste tires. Background Technology

[0002] When pyrolyzing waste tires, the waste tires are fed into the rotary pyrolysis furnace by a feeder. Each pyrolysis furnace is fed according to the specified amount each time. After the pyrolysis reaction is completed, the furnace body stops heating, the pyrolysis furnace motor and power supply are turned off, and air cooling is adopted. The heat of the furnace body is continuously removed by the fan. The cooling section lasts for 8 hours.

[0003] In existing pyrolysis reactors, heat is continuously removed from the reactor body by a blower during cooling. However, the amount of heat removed per unit volume of air is relatively small, requiring continuous air replacement to accumulate sufficient heat dissipation. The slow heat exchange rate between the air and the pyrolysis reactor wall makes it difficult to quickly transfer the heat from the reactor body to the air, resulting in excessive cooling time and reduced production efficiency.

Among them, the ends of the two first delivery pipes 2 away from the first delivery pump 4 are respectively fixedly connected to the corresponding second refrigeration box 12, and respectively communicate with the interior of the corresponding second refrigeration box 12.

[0022] Furthermore, a pyrolysis vessel 8 is fixedly sleeved on the inner wall of the heat insulation cover 6, and a feed pipe 11 communicating with the interior of the pyrolysis vessel 8 is fixedly connected to the upper surface of the pyrolysis vessel 8. The upper end of the feed pipe 11 extends through the upper surface of the heat insulation cover 6, which is located on the opposite side of the two water supply pipes 10.

The stirring rods 20 break up the agglomerates of the material, and the arc-shaped stirring plates 19 push the material to tumble up and down, so that the waste tire material is heated more evenly and the pyrolysis reaction rate is increased. After the pyrolysis is completed, the discharge pipe control valve is opened to discharge the product.
