Sludge filter press

Abstract

The invention discloses a sludge filter press. The sludge filter press comprises a driving motor 1, a driving planetary gear 2, a filter plate 3, filter cloth 4, a piston cylinder 5, a connecting rod6, a pressing plate hydraulic system 7, a piston cylinder hydraulic system 8 and a bracket 9; the filter plate is oppositely arranged on one side of the driving planetary gear; the filter cloth coatsthe filter plate; piston cylinders are fixedly mounted at two ends of the filter plate; a filtrate outlet is formed in the filter plate; the pressing plate hydraulic system is arranged on the side face of the piston cylinder. The filter plate, the piston cylinder and the pressing plate hydraulic system are fixedly connected through the connecting rod to form a fixed assembly body; the piston cylinder hydraulic system is mounted at the end part of the connecting rod; the driving planetary gear drives a subsequent rotating part to rotate; the pressing plate hydraulic system realizes horizontal reciprocating piston motion of a pressing plate through a pipeline hydraulic system of the pressing plate hydraulic system, sludge is subjected to filter pressing from the sludge with the water contentof 99%-98% to the sludge with the water content of 55%-75%, so that the purpose of sludge reduction is achieved, the structure is simple, the automation degree is high, and 24-hour continuous operation is realized.

Description

technical field [0001] The invention relates to a sludge filter press, in particular to a piston type sludge filter press. Background technique [0002] At present, my country's sewage treatment enterprises produce a large amount of sludge with high water content in the process of sewage treatment. There are a large amount of perishable organic matter, bacteria, viruses and heavy metals in the sludge. These sludge must be dehydrated for subsequent treatment and disposal. , and the sludge dewatering equipment currently used by sewage treatment enterprises in my country: drum centrifuge, belt dehydrator and plate and frame filter press, due to structural limitations, it is difficult to increase the pressure and centrifugal force of the equipment, and the moisture content of the sludge after dehydration is 75 %~85%, regardless of the subsequent disposal methods such as landfill, composting and incineration, the difficulty and cost of disposal are very high. Therefore, how to fur...
