Belt type squeezing filter press

Abstract

A belt type squeezing filter press comprises a conditioning box, a drum centrifugal machine and a filter press, an outlet of the conditioning box is connected with an inlet of the drum centrifugal machine, a sludge discharge port of the drum centrifugal machine is located above a material distribution device of the filter press, the material distribution device is located at the top of a rack, and an upper liquid receiving disc and a tensioning device are arranged below the material distribution device. The tensioning device is connected with the upper deviation adjusting roller, the upper deviation adjusting roller is connected with the upper filter belt, the upper filter belt is arranged on the upper filter belt carrier roller assembly, and a dewatering roller and a pressing roller are arranged in the upper filter belt carrier roller assembly and the lower filter belt carrier roller assembly; and the dewatering roller and the press roller are arranged in the upper filter belt carrier roller assembly in the filter press, the dewatering efficiency can be further improved, after sludge enters the belt press filter, water in the sludge is removed and the sludge is pressed into a filter cake under the action of a series of press rollers between the two mutually clamped filter screens, the requirement for outward transportation of the sludge cake is met, outward transportation cost is saved, and comprehensive treatment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection sludge treatment equipment, and in particular relates to a belt press filter press. Background technique [0002] Belt press filter is a high-efficiency, continuous operation solid-liquid separation equipment, which is widely used in sludge dewatering in urban domestic sewage, waterworks, and industrial sewage treatment in industries such as fermentation, papermaking, textile, printing and dyeing. Sludge with a moisture content of about 78-85% needs to be transported out for concentrated deep dehydration, incineration or other ways to reduce the amount and harmless treatment. As the requirements of the national environmental protection policy are getting higher and higher, some areas mandate that the moisture content of the sludge after dehydration must be ≤ 80%, otherwise the sludge is not allowed to be transported abroad; there are also sludge deep disposal units that cannot han...
