It is mainly used in industrial production of various industries and dehydration of various types of pollution in life and solid-liquid separation of some industrial materials. Sludge filter press is widely used in sludge dehydration in urban sewage treatment, chemical industry, oil refining, metallurgy, papermaking, leather making, food, coal washing, printing and dyeing and other industries. The equipment has the advantages of continuous operation, high degree of automation, energy saving, high efficiency, easy use and maintenance. It is an ideal equipment for sludge dehydration. The use of sludge filter press can save the investment in sludge thickening tank, reduce the floor space, and the sludge residence time is short, the dephosphorization effect is good, and the treatment efficiency is high.

[0003] In actual applications, the sludge plates treated by the filter press need to be removed from the machine. In order to efficiently collect these sludge plates, a special cement trough is usually installed at the bottom of the filter press. The sludge plates can slide down smoothly by gravity, and can be transported by a bulldozer later. However, as the operation continues, the newly dropped sludge plates may collide with the existing sludge plates in the cement trough. Since the surfaces of these sludge plates are relatively smooth and they still contain a certain amount of moisture, they are prone to partial splashing when they collide with each other. This situation requires the staff to maintain a certain distance during operation, away from the open fan-shaped area of ​​the cement trough to ensure safety. This undoubtedly increases the complexity of the work, reduces the operating efficiency, and brings certain inconveniences to the staff. Utility Model Content
