Problems solved by technology
Among them, the pressure filtration method has a large investment and high operating costs.
The sludge drying method has low investment and low operating costs, so sludge drying tanks are often used in places with sufficient space, but sludge drying tanks also have low drying efficiency and long processing time. Therefore, if the filter press method and the sludge drying tank drying method can be integrated, the sludge treatment efficiency will be greatly improved

Abstract
The invention relates to a sludge drying tank with a filter pressing function, which comprises a sludge drying tank body and a filter pressing device, wherein the sludge drying tank body comprises a tank wall, a tank bottom, brick piers, a filter plate, a filter material and a permeable vent pipe; a water outlet channel is arranged in the middle of the tank bottom; the brick piers are arranged onthe tank bottom in an array way; the upper ends of the brick piers are connected with the filter plate; the filter material is paved above the filter plate; the permeable vent pipe is inserted into the filter material; the filter pressing device comprises a support, an air cylinder, a pressing plate and a hooking plate; the support comprises a longitudinal rod and a cross rod which are arranged above the tank wall; the air cylinder is used for driving the pressing plate to move up and down; the upper end of the hooking plate is fixedly connected with the lower surface of the pressing plate; the lower end of the hooking plate stretches into sludge; the hooking plate comprises a connecting rod and a hooking claw; the hooking claw is hinged to the lower end of the connecting rod, and can be folded axially toward the connecting rod. According to the sludge drying tank provided by the invention, through additionally arranging the filter pressing device, the sludge infiltration and drying process can be accelerated.
Description
technical field [0001] The invention relates to sewage treatment technology, in particular to a sludge drying tank with a filter press function. Background technique [0002] Sludge treatment is an important part of sewage treatment. The sludge discharged from the sedimentation tank has a high water content, usually above 95%, so the sludge needs to be dried. There are mainly two methods of sludge drying: filter press filter and sludge drying tank. Among them, the pressure filtration method has a large investment and high operating costs. The sludge drying method has low investment and low operating costs, so sludge drying tanks are often used in places with sufficient space, but sludge drying tanks also have low drying efficiency and long processing time. Therefore, if the filter press method and the sludge drying tank drying method can be integrated, the sludge treatment efficiency will be greatly improved. Contents of the invention [0003] In order to solve the abov...
