Membrane filter press for sludge treatment

Abstract

The invention relates to the technical field of sludge treatment, in particular to a membrane filter press for sludge treatment. The membrane filter press for sludge treatment comprises a machine frame, a filter device and a hydraulic device, wherein the machine frame is provided with a cavity; the filter device is arranged in the cavity of the machine frame; the hydraulic device is arranged on the side of the machine frame; the filter device comprises a pressing plate, a membrane filter plate and filter cloth; the membrane filter plate is fixed in the cavity of the machine frame; the filter cloth is arranged along the upper end of the membrane filter plate and the lower end of the adjacent membrane filter plate; the pressing plate for tensioning the filter cloth is arranged on one side of the membrane filter plate; and a gap is reserved between the adjacent membrane filter plates. Compared with the prior art, the membrane filter press for sludge treatment is high in filter speed, good in separation effect and easy and convenient to operate, effectively reduces the water content of a mud cake, reduces consumption of water for industrial cleaning, reduces environmental pollution and reduces production cost.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a membrane filter press for sludge treatment. Background technique [0002] Filter press is the main filter equipment for sludge dewatering. At present, most of the filtration equipment used for sludge dewatering are belt filter presses and centrifuges. The disadvantage of using these two equipments to filter sludge is that the mud cake on the filter belt is squeezed by the shaft roller of the belt filter press. After a while, the water in the mud cake is difficult to drain quickly; while the mud cake filtered by the centrifuge using centrifugal force still contains high water. Due to the high water content of the mud cake filtered by these two equipments, the sludge cannot be transported after filtration, which affects the normal daily treatment capacity and working environment of the sludge. Contents of the invention [0003] The purpose of the present invention is...

Problems solved by technology

At present, most of the filtration equipment used for sludge dewatering are belt filter presses and centrifuges. The disadvantage of using these two equipments to filter sludge is that the mud cake on the filter belt is squeezed by the shaft roller of the belt filter press. In an instant, the water in the mud cake is difficult to quickly discharge; while the mud cake filtered by the centrifugal force of the centrifuge still contains high water

Due to the high water content of the mud cake filtered by these two equipments, the sludge cannot be transported after filtration, which affects the normal daily treatment capacity of sludge and the working environment.
