Common ones include belt filter presses, frame filter presses, membrane filter presses, etc., or evaporate the moisture in the sludge by heating the sludge. When treating sludge, the filter press generally dilutes the sludge through a stirring component to reduce the concentration of the sludge, making it easier for the sludge to pass through the filter medium and improve the efficiency and speed of filtration. During the dilution process, the sludge is placed in a stirring device and mixed with the solution, and then the evenly mixed sludge solution is pumped into the filter press through a high-pressure pump. However, during the sludge dilution process, the sludge and flocs will adhere to the inner wall surface of the stirring device, resulting in the inability to evenly mix the sludge and the solution, affecting the treatment efficiency of the filter press and resulting in poor mixing effect. Usually, the stirring time is increased, or the inner wall of the stirring device is manually scraped for intervention, which requires a lot of manpower and material resources and has a poor user experience.
