Plastic garbage crushing device

Abstract

The invention discloses a plastic garbage crushing device. The plastic garbage crushing device comprises four sections, wherein shells of the four sections are sequentially connected. The first section comprises a feeding channel provided with an extrusion roller and a first cavity provided with coarse and fine crushing rollers. The second section comprises a second cavity, a shaft barrel, spiralblades wound outside the shaft barrel and a first motor, wherein the shaft barrel is suspended and rotatably installed in the second cavity, and the rotation of the shaft barrel is driven by the firstmotor. The third section comprises a third cavity, a first crushing cutter and a second crushing cutter, wherein a plurality of arc-shaped openings are formed in two sides of the third cavity, and slicers on the first crushing cutter and the second crushing cutter can be cut into the arc-shaped openings to cut and crush plastic. The fourth section comprises a fourth cavity and a final crushing roller positioned in the fourth cavity, wherein the wall surface of the lower side of the fourth cavity is a mesh wall surface. The wall surfaces at the bottoms of the first cavity and the second cavityare both hole-type wall surfaces allowing water to penetrate through. On the one hand, plastic garbage can be crushed into extremely small particles, and on the other hand, the liquid in the plasticgarbage can be separated.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to plastic garbage shredding treatment. Background technique [0002] At present, plastic waste is disposed of in the following ways in most countries: landfill, incineration and pyrolysis. Although the above disposal methods will inevitably have an impact on the environment, landfill and incineration will still be the most important disposal methods until a more reasonable and large-scale disposal method is found. [0003] At present, when plastic waste is landfilled in China, it is usually directly landfilled, and crushing devices are rarely used to crush plastic waste before landfilling. Moreover, although some plastic waste crushing devices have also appeared on the market at present, these crushing devices generally have the following disadvantages: (1) plastic waste is usually mixed with a large amount of liquid, and the existing crushing devices cannot effectively crush the ...

Problems solved by technology

Although the above disposal methods will inevitably have an impact on the environment, landfill and incineration will still be the most important disposal methods until a more reasonable and large-scale disposal method is found.

[0003] At present, when plastic waste is landfilled in China, it is usually directly landfilled, and crushing devices are rarely used to crush plastic waste before landfilling.

Moreover, although some plastic waste crushing devices have also appeared on the market at present, these crushing devices generally have the following disadvantages: (1) plastic waste is usually mixed with a large amount of liquid, and the existing crushing devices cannot effectively crush the plastic waste during the crushing process. Separate these liquids from the garbage, and then treat them separately; (2) The degree of fragmentation is not enough, and the size of the fragments is large, resulting in a large gap between the fragments during landfill, which will increase the landfill required.
