Discharging device for treating waste tire pyrolysis solid products in regenerative pyrolysis furnace

Abstract

The invention discloses a discharging device for a heat accumulating type thermal decomposition furnace to treat pyrogenic decomposition solid products of a junked tire. The discharging device comprises a shell, a material laying plate used for containing the solid products, a chain board wheel transmission assembly, a driver and a plurality of material scraper blades. A discharge opening is formed in the shell. The material laying plate is movably arranged inside the shell. The chain board wheel transmission assembly is arranged inside the shell and placed above the material laying plate. The driver drives the chain board wheel transmission assembly to operate. The material scraper blades are respectively arranged on a transmission chain of the chain board wheel transmission assembly, the transmission chain drives the material scraper blades to move, and the material scraper blades push the solid products to the discharge opening. According to the discharging device, the traditional problems of material clamping, blocking and the like are solved, the continuous discharging purpose is achieved, the operating cost caused by abnormal maintenance and overhauling is greatly lowered, carbon black can be effectively prevented from being ground into powder, the potential risk caused by raised dust is avoided, and meanwhile the physical property of the solid products can not be damaged.

Description

Technical field [0001] The invention relates to the field of tire processing, and in particular to a discharging device for processing waste tire pyrolysis solid products in a regenerative pyrolysis furnace. Background technique [0002] At present, in the continuous pyrolysis process of tires, in order to achieve continuous pyrolysis of tires, a discharge screw is usually used to directly output the solid product from the pyrolysis furnace to achieve continuous discharge. After the solid product obtained after pyrolysis of the tire is squeezed by the screw, the iron wire in the solid product is separated from the carbon black. The thin iron wire is easy to form iron balls in the discharge screw, which will cause the screw of the discharge screw device to jam and affect The discharging screw normally discharges, and the broken solid product is easy to form carbon black dust, part of which enters the oil and gas pipeline with the oil and gas, adheres to the pipe wall, and blocks t...

Problems solved by technology

After the solid product obtained after tire pyrolysis is extruded by the screw, the iron wire in the solid product is separated from the carbon black, and the thin iron wire is easy to form iron balls in the discharge screw, which will cause the screw of the discharge screw device to be stuck in severe cases, affecting The normal discharge of the discharge screw, and the broken solid product is easy to form carbon black dust, part of which enters the oil and gas pipeline together with the oil and gas, adheres to the pipeline wall, and blocks the pipeline

The other part will float into the atmosphere, which will pollute the environment, and seriously affect the health of operators, pose safety hazards, and seriously affect the continuity of production
