[0002] A bar screen is a solid-liquid separation device that can continuously remove impurities from fluids. It is an indispensable special equipment in the production processes of industries such as urban sewage treatment, waterworks, power plant inlets, textiles, food processing, papermaking, and leather. It is currently the most widely used solid-liquid screening equipment in China.
[0003] A bar screen for wastewater treatment is disclosed in Chinese patent CN215543659U. This bar screen, after crushing and compressing the waste, occupies little space and is less likely to produce foul odors, achieving a good waste treatment effect. However, while solving the problem, this bar screen for wastewater treatment has the following disadvantages:
