[0002] Environmental protection equipment refers to mechanical products, structures and systems manufactured and built by production units or construction and installation units for controlling environmental pollution and improving environmental quality. Some people also believe that environmental protection equipment refers to mechanical processing products for controlling environmental pollution, such as dust collectors, welding fume purifiers, single water treatment equipment, noise controllers, etc. Environmental protection machinery uses solid waste crushing devices. Crushing is a unit operation in chemical production and a purely mechanical process operation. For solid raw materials that are too large to be used or semi-finished products that do not meet the requirements, they must be processed to make them smaller. This process is called crushing.

[0003] The environmental protection machinery solid waste on the market needs to be crushed in the subsequent treatment. The mechanical solid waste cannot be filtered after crushing during the crushing process. During the filtering, some incompletely crushed particles will be retained on the top of the filter. After a long time, too many particles will accumulate on the top of the filter, resulting in the inability to continue filtering. The filtering work needs to be suspended and the incompletely crushed particles must be cleaned up before work can be carried out, thereby reducing the crushing efficiency. For this reason, we have developed a new environmental protection solid waste crushing device. Summary of the invention
