[0002] With the acceleration of urbanization and the improvement of industrialization, the amount of sludge generated in sewage treatment plants and industrial production processes is increasing. These sludges are usually rich in water, contain organic matter, solid particles and various pollutants, and if they are directly discharged without treatment, they will have a serious impact on the environment and human health.

[0003] A filter dewatering machine is a device specially used to separate solids and liquids from a liquid mixture. It uses a filter medium to trap solid particles suspended in the liquid on the filter medium, and then discharges the liquid portion from the filter medium to achieve solid-liquid separation. In most existing dewatering machines, solid particles may accumulate on the filter cartridge during long-term operation, causing blockage. The liquid cannot pass through the filter cartridge smoothly, which will increase the pressure inside the system and may cause damage to the equipment or unstable operation, reducing the operating efficiency of the dewatering machine. In addition, after sewage is put into the equipment, when the sludge is dewatered, the sludge is driven to rotate inside, causing the sludge to flow to the outside. When the dewatered sludge is taken out, the operator needs to use external tools and means to take out the sludge, which may increase the downtime in the production process, thereby reducing work efficiency and production capacity, and increasing the difficulty and time cost of cleaning.
