Abstract

The invention relates to a lift-type filter disk for sludge concentration treatment equipment. The lift-type filter disk comprises a filter disk which is installed in a concentration settling drum and sheathed outside the outer wall of a stirring drum, wherein the filter disk is uniformly distributed with filter holes; the filter disk is connected with a cam drive unit on the top of the concentration settling drum through a connecting rod; a spring is installed between the connecting rod and the top of the concentration settling drum; the cam drive unit comprises a cam which forms a rolling contact with the upper end of the connecting rod; and the cam is driven by a lifting motor. By adopting the auxiliary extrusion effect of the filter disk on sludge water, the stirred sludge can be further dispersed, thereby being beneficial to filter discharge and concentration settling, and enhancing the concentration treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sludge concentration treatment device. Background technique [0002] In the process of urban sewage treatment, the water content of sludge produced by water purification and water treatment is generally 99.3% to 99.7%, activated sludge is generally 99.2% to 99.6%, and mixed sludge is generally 97% to 98%. . Municipal sludge is characterized by less solid objects and more water. Therefore, sludge dehydration needs to be concentrated before dehydration to reduce the moisture content of sludge, so that the volume of sludge can be reduced to facilitate sludge dehydration treatment. [0003] Traditional sludge concentration methods can be divided into three methods: gravity concentration, air flotation concentration and centrifugal concentration. Gravity concentration is to use the principle of sedimentation to concentrate sludge, which is divided into i...
