Sludge extrusion device capable of preventing non-uniform sludge distribution from affecting drying effect

Abstract

The invention relates to the technical field of sludge treatment equipment, and discloses a sludge extrusion device capable of preventing non-uniform sludge distribution from affecting a drying effect. The sludge extrusion device comprises a shell, wherein a feeding pipe is arranged in the shell; a mounting block is fixedly mounted on one side, close to the feeding pipe, of the shell; a piston ball is arranged in and slidably connected with the mounting block; and the side, close to the shell, of the mounting block is rotationally connected with a reciprocating screw rod. According to the sludge extrusion device capable of preventing non-uniform sludge distribution from affecting the drying effect, the reciprocating screw rod drives a compression block to intermittently compress sludge, and then a locking block drives a gear to intermittently rotate, so equivalent extrusion forming of the sludge is realized, the forming effect of the sludge is better, gaps in the sludge are more uniform, and sludge drying effect is improved to a certain extent; meanwhile, the shape of extruded sludge is fixed, so transportation is more convenient; and fuel consumption is reduced during drying, so compared with existing equipment, the sludge extrusion device is more energy-saving and more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a sludge extruding device which prevents uneven distribution of sludge from affecting the drying effect. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system. It is mainly the process of reducing, stabilizing and harmless sludge such as concentration, tempering, dehydration, stabilization, drying or incineration. [0003] The existing sludge drying treatment is mainly through screw pumps, sludge extruders, drying hosts, biological filters, etc. Among them, the sludge extruder is one of the commonly used equipment, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sludge extruding device that avoids the influence of uneven distribution of sludge on the drying effect, which has the advantages of good sludge forming effect, uniform void distribution, good drying effect, convenient transportation, The advantage of less consumption solves the problems of poor sludge forming effect, uneven voids, poor drying effect, inconvenient transportation, and high fuel consumption.
