Detailed explanation of potato residue plate and frame filter press dehydrator
The plate and frame filter press dehydrator can be used in various sludge dehydration treatment fields in many industries, and can directly dewater sludge with a moisture content of more than 90% to dry sludge with a moisture content of 15-45%.
As a type of sludge dewatering equipment, the dewatering principle of the plate and frame filter press is the same as that of the belt filter press, but the plate and frame are different in design from the belt filter press. The filter belt filter press is driven by the roller to drive the filter belt to run continuously. The sludge runs continuously on the filter bag to dehydrate, but the plate and frame run intermittently. After entering a part of the sludge, the filter press is completed, and then the next intake Mud dehydration.
Let us understand the basic composition of the lower plate and frame filter press from the schematic diagram of the lower panel frame filter press:
During the operation of the plate and frame filter press, the sludge pump sends the sludge added with chemicals (conditioning agent, dehydrating agent) to the filter press, and the sludge is evenly distributed in the filter press. This part of sludge solids began to accumulate on the filter cloth, and the preliminary filtration began. The separation of most of the mud and water in the dosing sludge is accomplished through the accumulation of filter cloth between the plates and frames. At first, some fine particles of sludge can pass through the filter cloth, but more and more solids begin to be intercepted during the filter cloth filtration process. The sludge layer on the interception is like a pre-coating Layer, which traps particles and forms a filter cake.
The above picture shows the relationship between filter cloth, filter plate, mud cake and filtrate. It can be seen that the plate and frame filter press is more like a non-rotating filter belt filter press. The sludge dewatering process is completed by squeezing the filter cloth fixed on the filter plate again and again.
The filter press uses hydraulic and pressure devices to apply pressure to the filter plates, and the cavity between the filter plates is completely filled with sludge cake. At this time, the squeezed filtrate flows out through the corners of the filter plate, the filtrate drain valve is opened, and the filtrate is discharged out of the filter press through an outlet to complete a filter press process.
