Discarded tire liquid nitrogen frozen grinding box

Abstract

The invention discloses a discarded tire liquid nitrogen frozen grinding box. The discarded tire liquid nitrogen frozen grinding box comprises a box body, a feed port, a sealing door, a connecting rope, a sliding plate, supports, turning wheels, support legs, a discharge port, a sealing cover, a high-pressure liquid nitrogen bin, a nitrogen delivery pipe, a solenoid valve, a spray pipe, spray nozzles, a pressure reduction bin, a spring, a draught fan, an annular gas pipe, gas spray heads, an gas discharge duct, a sealing rubber rod and a bypass pipe. The four support legs are uniformly mountedat the bottom of the box body. The feed port is formed in the upper portion of the sidewall of the box body, The sealing door is rotatably connected to the bottom end of the feed port. The sliding plate is rotatably mounted in the position, located under the feed port, of the inner wall of the box body. The two supports are symmetrically fixed to the inner wall of the box body and located betweenthe feed port and the sliding plate. The discarded tire liquid nitrogen frozen grinding box intermittently sprays liquid nitrogen and intermittently blows gas to stir rubber blocks; the crushing rateof the rubber blocks is increased; the liquid nitrogen is saved; the rubber blocks are put in and taken out conveniently. The discarded tire liquid nitrogen frozen grinding box is simple in structureand safe in use.

Description

technical field [0001] The invention belongs to the technical field of waste tire treatment, and in particular relates to a liquid nitrogen freezing crushing box for waste tires. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which ...
