Background

Tire waste disposal is a major problem in environmental protection. The quantity of tire waste produced each year in China is huge. Direct combustion treatment can cause very serious environmental pollution, deep land burying has insufficient land, tires are not easy to degrade, and the land can be polluted. Transporting tires to a thermal power plant to generate electricity is also a treatment, but the resulting benefits are very low. The tire can be used as a road base after treatment, and the rubber is preferably recycled and changed into other rubber products for use. Before the regeneration treatment, the tires are disassembled into rubber blocks and then crushed into rubber particles. After the crushed rubber particles are subjected to wire removing treatment, the crushed rubber particles need to be conveyed to a softening process for softening treatment. In the wire removing step, the steel wire cannot be completely removed, and the steel wire mixed in the rubber particles has a large influence on the softening process, and therefore, the steel wire needs to be cleaned. The crushed rubber particles carry a large amount of heat, so that the rubber particles have certain viscosity, and the steel wires in the rubber particles are difficult to remove. Simultaneously in initial screening process, some large granule rubbers receive the extrusion also can fall to the tiny particle rubber in, and in transportation process, these large granule rubbers volume rebound grow, and the going on of softening of rubber also can be influenced to the large granule rubber of sneaking into.

Has the advantages that: the utility model discloses a rubber granule screening conveyor sieves the large granule rubber that thoughtlessly gets in the tiny particle rubber earlier through setting up screening mechanism and removes, simultaneously, in reciprocal screening process, the part glues glutinous rubber group and also can be loose because of reciprocating motion. The material that falls into in the tiny particle rubber silo enters into the lifting pipe way after the transfer of first conveyer belt, under the effect of negative pressure wind, tiny rubber granule is promoted in cyclone, simultaneously, at the promotion in-process, tiny rubber granule is also being cooled down, and granule viscidity descends, and in addition the torrent effect, rubber and steel wire realize the separation more easily. Other heavy impurities, such as stones, steel wires and the like, are difficult to lift up, and fall into the bottom of the lifting pipeline, so that the small rubber particles are purified.
