Embodiment Construction

[0008] The specific embodiment of the present invention is described in conjunction with accompanying drawing, as figure 1 As shown, the waste tire thermal cracking treatment device includes a cracking furnace, an internal heating system, and an external heating system.

[0009] The cracking furnace includes a support shaft 21, a hollow shaft 16, and a rotary kiln shell 10. The support shaft 21 is fixed on the outer wall of the hollow shaft 16 through a fixing mechanism 23; the support shaft 21 and the hollow shaft 16 are installed in the rotary kiln shell 10, and the support shaft 21. The hollow shaft 16 and the rotary kiln shell 10 are coaxial, and have an inclination angle of 0°~5° with the horizontal position; the support shaft 21 and the hollow shaft 16 do not rotate with the rotary kiln shell 10, and the rotary kiln shell Front wheel belt 5, rear wheel belt 12 and gear ring 7 are installed on 10 outer walls, and gear ring 7 is meshed with transmission gear 25, and transm...

Abstract

The invention relates to a waste tire recycling and reusing device, in particular to a thermal cracking treatment device for waste tires. A support shaft, a hollow shaft and a rotation kiln cylinder of a cracking furnace are coaxial, wherein an inlet is formed in the front end of the rotation kiln cylinder; an outlet is formed in the tail end of the rotation kiln cylinder; a thermal cracking solid collector is communicated with the outlet in the tail end of the rotation kiln cylinder; a discharging opening is formed in the thermal cracking solid collector; a through hole is formed in the hollow shaft and is communicated with an inner cavity of the rotation kiln cylinder; one end of the hollow shaft extends to the exterior of the rotation kiln cylinder; an inner heating system comprises an inner heating tube; an outer heating system comprises an outer cylinder; a high-temperature smoke inlet and a waste heat smoke outlet are formed in each heating area of the outer cylinder. Waste tires are cut into blocks, are subsequently fed into the rotation kiln cylinder of the cracking furnace and are moved to the outlet; the inner heating system and the outer heating system are used for simultaneously heating the rotation kiln cylinder; the high-temperature smoke generated by the combustible waste gases through the thermal cracking reaction enter the outer heating system and the inner heating system respectively.

Description

technical field [0001] The invention relates to recycling equipment for waste tires, in particular to a thermal cracking treatment device for waste tires. Background technique [0002] With the rapid development of the automobile industry, the amount of waste tires is also increasing rapidly. The increasing amount of waste tires has become a global problem. According to statistics, more than 700 million old tires are replaced every year in the world, and more than 10 million tons of waste tires have been stored in the world to be treated urgently. In industrialized countries, about one waste tire is produced per capita every year. There are more than 250-300 million waste tires for vehicles in the United States every year. At present, the production of rubber products in the United States is 5 million tons, of which tires are 3 million per year. These tires will all be scrapped within 2-3 years; about 1.8-2 million tons of waste tires are produced in Europe every year, and...
