Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a rubber crushing device. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. Its unique elasticity makes it one of the important basic industries of the national economy. Rubber not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber parts for heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. The raw materials needed for rubber production need to be crushed.

[0003] After searching, a raw material crushing equipment for polymer rubber production with announcement number CN210415109U includes a material guide table, an equipment shell, a dust removal structure, a second crushing roller and a screen plate. The material guide table is fixed to the bottom of the equipment shell, and a scraper motor is installed at the bottom of the equipment shell at the position of the material guide table, and the output end of the scraper motor is installed with a first rotating shaft through a coupling, and the top of the first rotating shaft passes through the equipment shell and extends to the inside of the material guide table. The bottom ends of the legs on both sides of the material guide table are provided with discharge ports, and legs are fixed on both sides of the bottom end of the equipment shell. A first rotating roller is provided on the top of the equipment shell, and both ends of the first rotating roller are hinged to the inner wall of the equipment shell, and a first crushing roller is fixed on the outer wall of the first rotating roller. The utility model not only reduces the pollution of the raw material crushing equipment to the air, improves the crushing effect of the raw materials, but also improves the discharge efficiency of the raw materials;

[0004] Based on the above patent, a dust removal chamber, a sparse-porous filter, a dense-porous filter, an activated carbon adsorption layer, a processing box, an air pump and an air pipe are provided.
