Garbage tearing crushing machine

Abstract

The invention discloses a garbage tearing crushing machine comprising a crushing box body, wherein the crushing box body is internally provided with at least one pair of mutually-paired tearing rollers; tearing cutterheads are fixedly arranged on each tearing roller at intervals; each of the tearing cutterheads of the mutually-paired tearing rollers is provided with a tearing cutter tooth inserted to a gap between the tearing cutterheads of the opposite tearing rollers; a blanking gap for avoiding shear force generation is arranged between each tearing cutter tooth and the side wall of the gap between the tearing cutterheads of the opposite tearing rollers; and when the garbage tearing crushing machine works, hard matters such as little silt and pebbles are discharged through the blanking gaps, and hard matters such as large stones as well as cloth, plastics and the like are also discharged through the blanking gaps after being continuously gnawed, beaten, torn and crushed by the tearing tool teeth, so that the abrasion of shearing blades is greatly reduced. Garbage is crushed through tearing, beating and gnawing, so that tearing tool tooth abrasion caused by shearing is avoided; and experiments prove that the maintenance-free time of the crushing machine in continuous working can belonger than one year, and the technical effect is extremely remarkable.

Description

technical field [0001] The invention relates to a garbage disposal device, in particular to a garbage crushing equipment. Background technique [0002] With the development of society, garbage pollution has become a serious social problem, and garbage disposal has become a thorny technical problem. [0003] The advanced garbage treatment process first needs to crush the garbage, but the technical problem of garbage treatment is that the composition of the garbage is complex, and the garbage contains plastic bags, waste cloth, waste rubber, waste wood, silt, waste steel and other components that are extremely difficult to break , and the garbage is wrapped in plastic bags, and the garbage bags need to be opened during the crushing process to be shredded. [0004] At present, the most advanced crushing machinery at home and abroad is the double-shaft crusher. Its principle is to shear and crush the material through the shearing cutter head. The crushing efficiency is extremel...

Problems solved by technology

[0005] The applicant tried to use a double-shaft crusher to crush the garbage. During the operation, the shearing cutter head was worn out after 72 hours of continuous operation, making the double-shaft crusher unable to work, and the replacement of the cutter head would cause huge maintenance costs. It also reduces the crushing efficiency of the garbage, and is simply not competent for the crushing work of the garbage.

The reason is that during the shearing process of the garbage, because the garbage contains sediment, stones and other hard materials, the shearing cutter head wears extremely fast, resulting in the failure of the double-shaft crusher.
