Problems solved by technology

[0003] The preparation of regenerated rubber in the prior art is to put the whole steel wire tire into the crushing device for crushing, and then perform magnetic separation on the crushed particles to screen out the steel wire in the particles, but the existing crushing equipment is in use. There are the following problems: 1. When the crushing is not sufficient, the particles are too large and heavy. The crushing device continuously squeezes the steel wire and particles in the process of crushing the tire. Some steel wires may be inserted into the large particles, and the steel wire cannot be separated from the 2. When the crushing is too sufficient, since the surface of the steel wire is usually coated with an anti-rust metal layer, the anti-rust metal layer will be broken into metal powder, which cannot be screened out by magnetic separation
Both of the above situations cause the regenerated rubber powder or rubber granules to contain metal, which reduces the purity of the regenerated rubber.

Abstract

The invention relates to the field of rubber recycling and discloses a production system for multi-grade crushing and processing of reclaimed rubber. The production system comprises a layer peeling device, a magnetic separation device, a raw material conveying device and a crushing device, wherein the layer peeling device comprises a rack, a clamping mechanism and a motor; the clamping mechanism is in sliding connection with the rack; the rack is provided with a telescoping mechanism; a layer peeling cutter is fixed below the clamping mechanism; a guide plate and a material receiving frame arearranged below the layer peeling cutter; the magnetic separation device comprises a first conveyor belt and a second conveyor belt; the first conveyor belt and the second conveyor belt are parallel to each other; the second conveyor belt has permanent magnetism; a gap is formed between the first conveyor belt and the second conveyor belt; a cutting saw is arranged beside the gap; the raw materialconveying device comprises a feeding end and a discharging end; the feeding end is located below the first conveyor belt; the discharging end of the raw material conveying device is connected with afeeding opening of the crushing device. The invention aims at providing the production system which prevents the purity of the reclaimed rubber from being influenced by a bead wire when a bead wire isused for producing the reclaimed rubber.

Description

technical field [0001] The invention relates to the field of rubber recovery. Background technique [0002] Reclaimed rubber is usually processed from car tires. Car tires are cleaned, crushed, magnetically separated, winnowed and multi-stage sieved to obtain rubber powder or rubber granules. However, with the development of the automobile tire industry and people's increasing demand for tire safety, more and more automobile tires use steel wire radial tires (referred to as steel wire tires). The structure of steel wire radial tires is as attached figure 1 As shown, from the inside to the outside are the bead (including the bead wire), the sidewall, the carcass cord layer, the steel belt layer and the tread (there are usually tread patterns and tread grooves on the tread). [0003] The preparation of regenerated rubber in the prior art is to put the whole steel wire tire into the crushing device for crushing, and then perform magnetic separation on the crushed particles to...
