Crusher

Abstract

The invention discloses a crusher which comprises a machine shell, a screw rod feeding mechanism, a movable knife, a fixed knife, a movable cutter, a fixed cutter, an airflow cavity conduit and a first positive pressure airflow inlet, wherein the screw rod feeding mechanism, the movable knife, the fixed knife, the movable cutter and the fixed cutter are arranged in the machine shell, the fixed knife or / and the movable knife is / are provided with a fixed knife through hole or / and a movable knife through hole, airflow is radiated by the airflow cavity conduit through the fixed knife through hole or / and the movable knife through hole, so as to form a jet flow air curtain layer between a movable knife work surface and a fixed knife work surface, so that the airflow is radiated towards the movable knife work surface or the fixed knife work surface or towards both the movable knife work surface and the fixed knife work surface. According to the crusher, the problem existing in rubber powder processing is eradicated, the effect of static electricity caused by abrasion of rubber powder is solved by utilizing wind and ion flow, and the influence of the static electricity on processing is eliminated. Made of a low temperature material, the rubber powder is easy to soften and can change the property easily, and the intelligent wind can be used for eliminating the static electricity and simultaneously lowering the temperature of a grinding material, a grinding knife as well as a grinding disk.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a crusher, in particular to a rubber crusher. Background technique [0002] Nowadays, in order to make the rubber in old tires reusable, there are rubber shredders. [0003] Existing rubber crushers generally come in three types: [0004] (1) The cone-shaped rubber breaker requires manual adjustment of the equipment, which is laborious and laborious, and the output and quality fluctuate greatly. The working temperature of the grinding disc is also uncontrollable, often due to excessive temperature, there will be smoke and scorching of the rubber powder. [0005] (2) Steel plate shearing type rubber breaker, the defect is that the steel wire will remain in the equipment, and the remaining steel wire will easily cause the temperature of the rubber powder to be high through friction, resulting in smoke and scorching of the rubber powder. [0006] (3) The double-groove ...

AI Technical Summary

Problems solved by technology

[0004] (1) The cone-shaped rubber breaker requires manual adjustment of the equipment, which is laborious and laborious, and the output and quality fluctuate greatly

The working temperature of the grinding disc is also uncontrollable, often due to the high temperature, there will be smoke, which will cause the rubber powder to burn

[0005] (2) Steel plate shear type rubber breaker, the defect is that the steel wire will remain in the equipment, and the remaining steel wire will easily cause the temperature of the rubber powder to be high through friction, resulting in smoke and scorching of the rubber powder

[0006] (3) The double-groove roller-type rubber breaker has the disadvantages of low efficiency and high energy consumption; the rubber powder produced by the assembly line of 6 equipment is only 20 mesh

[0007] To sum up, the existing rubber breakers are usually cooled by water. The disadvantages are: 1. The cooling effect is not good, and it can only cool the surface of the grinding disc in contact with water; Powders stick together due to mutual static electricity

[0008] The existing rubber breaker cutters do not conform to the principle of rubber crushing; therefore, the energy consumption is high, the output is low, it is easy to generate heat, and it takes up a lot of land. The reprocessing method is no longer suitable for the current international development and energy saving requirements.

[0009] Under normal temperature conditions, the rubber powder produced by the rubber breaker is volatile and easy to form agglomerates, so talcum powder needs to be added, and the filter performance is poor, and the rubber powder needs to be separated by hand kneading

Existing rubber breakers can only recycle and reuse low-quality rubber powder materials, which have low recycling value and cannot be used in the field of high-grade rubber.
