Plate and frame sludge filter press

Description

The plate and frame sludge filter press is an efficient sewage treatment equipment, mainly used for sludge dewatering. Its core components include frame, filter plate, filter cloth, hydraulic system and control system. The frame is usually made of high-strength carbon steel with good load-bearing capacity; the filter plate is made of corrosion-resistant material, which can withstand high pressure and effectively isolate sewage and sludge; the filter cloth is used to filter the water in the sludge; the hydraulic system provides the necessary filter pressure so that the filter cake formed between the filter plates can be effectively squeezed to achieve the purpose of dehydration; the control system is used to monitor the entire work process and perform automatic control to improve work efficiency.
Working principle
The work process of the plate and frame sludge filter press mainly includes several steps: feeding, filtration, discharge and cleaning:
.Feeding: The sewage is pumped into the feed port of the filter press, the filter cloth separates the sludge from the water, the sludge is deposited between the filter plates to form a filter cake, and the water enters the drainage pipe through the filter cloth.
.‌Filter pressing‌: After the feeding is completed, the hydraulic system starts to apply high pressure to the filter plate to further squeeze the filter cake, so that the water is squeezed out and the dehydration effect is achieved.
.‌Discharge‌: When the dehydration degree reaches the requirement, the hydraulic system releases the pressure and the filter cake is discharged.
.‌Cleaning‌: Regular cleaning of the filter cloth can extend its service life and keep the equipment working efficiently.
‌Advantages‌:
.‌Efficient dehydration‌: It can reduce the moisture content of the sludge to a very low level, reducing the burden of subsequent treatment.
.‌Easy operation‌: With hydraulic automatic control, the operator only needs to monitor the parameters, reducing labor costs.
.‌Strong adaptability‌: It is suitable for a variety of sludge types, including urban sewage, industrial wastewater, etc.
.‌Resource recovery‌: The dried filter cake can be used as fertilizer, building materials, etc., which is in line with modern environmental protection concepts.
