Urban garbage bag-breaking crushing device with knife cleaning function

Abstract

The invention discloses an urban garbage bag-breaking crushing device with a knife cleaning function. The urban garbage bag-crushing crushing device is characterized by comprising a shell and a crushing chamber located in the shell, wherein a rotating shaft is arranged in the crushing chamber; a roller is fixedly mounted on the rotating shaft; a plurality of five-edge sharp knife heads are distributed on the roller; a knife cleaning device matched with the five-edge sharp knife heads is further arranged in the crushing chamber; the knife cleaning device is connected with a hydraulic device for controlling the knife cleaning device to open and close; a tooth board which is matched with the five-edge sharp knife heads to crush materials is further arranged in the crushing chamber; and teeth are welded on the tooth board. The crushing device can well realize a pretreatment technique for garbage resource utilization. The crushing device can effectively treat various hard materials and flexible materials, has functions of preventing winding, breaking a large piece and breaking a large bag, and improves the crushing efficiency in garbage treatment.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a bag-breaking and crushing device for urban domestic garbage with a knife cleaning function. Background technique [0002] With the rapid development of the country's economy, the amount of municipal solid waste has increased dramatically. In 2010, the national urban domestic garbage removal volume reached 150 million tons, and the landfill and stacking of garbage occupied more than 800,000 mu of land. Two-thirds of the large and medium-sized cities in the country were surrounded by garbage, and one-quarter of the cities had already There is no suitable place for dumping garbage, and it is difficult to select a site and construct a new garbage dump. It is estimated that by 2020, the volume of municipal solid waste removal will reach 250 million tons, and the problem of waste disposal is imminent. [0003] my country's garbage disposal mainly adopts landfill, c...

AI Technical Summary

Problems solved by technology

Its main disadvantage is that the bags are not completely broken, and the crushing capacity of large pieces is limited, and the garbage cannot be crushed to a certain particle size.

It brings great difficulties to the subsequent garbage sorting (whether it is drum screening or airflow sorting)
