Pretreatment device for preparing colloidal particles by using waste tire rubber blocks

Abstract

The invention discloses a pretreatment device for preparing colloidal particles by using waste tire rubber blocks. The pretreatment device for preparing the colloidal particles by using the waste tirerubber blocks comprises a pre-cooling chamber, a freezing chamber, a vibration plate and a vibration mechanism; the pre-cooling chamber is obliquely arranged, and a feeding opening and an air outletare formed in the upper end of the pre-cooling chamber; the freezing chamber is in communication with the lower end of the pre-cooling chamber, and an air inlet and a discharging port are formed in the end, away from the pre-cooling chamber, of the freezing chamber; the vibration plate is arranged in the pre-cooling chamber and is opposite to the feeding hole; and the vibration mechanism is connected with the vibration plate and used for driving the vibration plate to vibrate. According to the technical scheme, rubber blocks are frozen, on one hand, friction heat generated during smashing canbe offset, and rubber particles are prevented from being in a desulfurized or semi-desulfurized state; and on the other hand, the elongation at break of the colloidal particles can be reduced, the colloidal particles are easy to crush, and the crushing heat can be greatly reduced, so that the yield and quality of rubber powder are improved.

Description

technical field [0001] The invention relates to the field of processing waste tire rubber blocks, in particular to a pretreatment device for preparing rubber particles from waste tire rubber blocks. Background technique [0002] With the rapid development of my country's economy, the transportation industry is also developing at a high speed, and the parts of vehicles are often inseparable from tires. The widespread use of tires has led to a rapid increase in the number of waste tires, but it is very difficult to recycle and comprehensively utilize waste tires. [0003] Waste tires are full of good things, mainly composed of synthetic rubber and natural rubber, textiles, anti-aging agents, carbon black and other materials, of which the mixture of natural rubber and synthetic rubber is as high as 55%-60%, metals account for about 25%, mainly High-quality steel wire that enhances the rigidity and strength of tires. These substances have high economic value, so the reuse of w...
