Plate and frame sludge filter pressZui was first applied to chemical dehydration machinery. Although the plate and frame filter press operates intermittently, requires a large investment in infrastructure equipment, and has a low filtration capacity, it is still widely used in some small-scale sewage treatment plants due to its advantages such as high filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and consumption of conditioning drugs. Next, we will introduce the working principle of the plate and frame sludge filter press and the factors that should be considered when selecting.
1Plate and frame sludge filter pressworking principle
The liquid to be filtered enters each filter chamber through the feeding hole at the top plate end under a certain pressure through the feeding pump, passes through the filter cloth, and the solid matter is trapped in the filter chamber, gradually forming a filter cake; The liquid is discharged outside the machine through the outlet holes on the plate frame. As the filtration process progresses, the filtration of the filter cake begins, the thickness of the mud cake gradually increases, and the filtration resistance increases. Stop filtering when the filter cake reaches a certain thickness or fills the entire frame. Open the frame, remove the filter cake, clean the filter cloth, reinstall, and proceed to the next cycle.
IIPlate and frame sludge filter pressWhat factors should be considered when selecting equipment?
(1) Requirement for solid content of mud cake. Compared with other types of dewatering machines, the plate and frame filter press generally has the highest solid content in the sludge cake, up to 35%. If considering the factor of reducing the land occupation of sludge stacking, the plate and frame filter press should be the preferred solution.
(2) The material of the framework.
(3) The material of the filter plate and filter cloth. Corrosion resistance is required, and the filter cloth should have a certain tensile strength.
(4) The movement method of the filter plate. It is required to be fully automatic or semi-automatic through hydraulic and pneumatic devices to reduce the labor intensity of operators.
(5) Filter cloth oscillation device to make the filter cake easy to fall off.
