[0002] With the acceleration of urbanization and the rise in industrialization, the amount of sludge generated by sewage treatment plants and industrial production processes continues to increase. This sludge is often rich in water and contains organic matter, solid particles, and various pollutants. If discharged directly without treatment, it will have serious impacts on the environment and human health.

[0003] The screw extrusion dehydrator utilizes the screw extrusion principle to separate the water and solids in the sludge by placing it in the screw machine and using mechanical extrusion to achieve the purpose of dehydration. When existing equipment is performing dehydration, most of the time it discharges sewage, which may contain solid particles or other impurities. These impurities may enter the internal and external components of the screw extrusion dehydrator, causing damage or failure of the equipment and shortening its service life. In addition, when processing sludge or other materials, solid particles or impurities may remain inside the screw extrusion dehydrator. These may accumulate on the screw or other components, causing equipment blockage or failure, increasing processing time and energy consumption, and reducing production efficiency.
