A domestic garbage shredder

Abstract

The invention discloses a household garbage crusher. The household garbage crusher is characterized in that a vertical crushing box is divided into an upper crushing cavity at the upper portion and a lower crushing cavity at the lower portion; a feeding inlet is formed in a top cover of the upper crushing cavity, and the upper crushing cavity is vertically communicated with the lower crushing cavity; the upper crushing cavity is horizontally provided with a pair of parallel square hammer crushing rotors, and square hammers capable of rotating are hinged to the square hammer crushing rotors; the square hammer crushing rotors rotate at constant speed in opposite directions; the lower crushing cavity is horizontally provided with a pair of parallel sheet hammer crushing rotors, and sheet hammers capable of rotating are hinged to the sheet hammer crushing rotors; and the sheet hammer crushing rotors rotate at differential speeds in opposite directions. According to the household garbage crusher, on the basis of the two-stage crushing processing manner, soft and hard materials in household garbage and large materials can be sufficiently crushed, and the requirement for follow-up processes is met.

Description

technical field [0001] The invention relates to a garbage crusher, more specifically to a crusher applied to domestic garbage crushing. Background technique [0002] With the development of the economy, the expansion of the city scale, and the acceleration of the urbanization process, the generation and accumulation of urban domestic waste in my country are also increasing year by year. At present, there are three main ways to deal with garbage: landfill, composting and incineration. No matter which treatment method is used, it is necessary to pretreat the garbage. For landfill waste, crushing and pretreatment can reduce the transportation volume and transportation costs. For incineration and composting waste, crushing and pretreatment is conducive to the incineration and composting process. At present, the most widely used garbage crushers mainly include hammer crushers, impact crushers and shear crushers. Hammer crushers and impact crushers can effectively crush hard and ...

AI Technical Summary

Problems solved by technology

At present, the most widely used garbage crushers mainly include hammer crushers, impact crushers and shear crushers. Hammer crushers and impact crushers can effectively crush hard and brittle materials in garbage, but The crushing effect on tough materials in domestic waste is poor

The shear crusher can effectively crush tough materials, but it is not ideal for the crushing and fine crushing of large and hard materials

Since urban waste in my country is generally a mixture of unclassified materials, including hard and brittle materials such as glass, ceramics, and bricks, as well as soft materials such as cloth strips, plastics, and paper, and other materials, the current simple crushing method does not not fully applicable
