City sludge solid impurity separation mechanism

Abstract

The invention relates to a city sludge solid impurity separation mechanism which comprises a sludge filtering mechanism and a sludge extrusion mechanism, wherein the sludge filtering mechanism is usedfor containing sludge; the sludge extrusion mechanism is used for extruding the sludge filtering mechanism; the sludge filtering mechanism is connected with the sludge extruding mechanism through a steel wire rope; a plurality of filtering holes are formed in the sludge filtering mechanism; the sludge extruding mechanism is used for extruding and filtering sludge after being pressed down; the sludge extruding mechanism is lifted up to drive the sludge filtering mechanism to turn over through the steel wire rope to automatically pour out compacted impurities. As further improvement of the mechanism, the sludge filtering mechanism comprises a central plate, two side filtering plates which are rotationally arranged on two sides of the central plate, and two sliding plates which are respectively rotationally connected with the two side filtering plates; the two sliding plates are respectively arranged on two support bases in a sliding manner; the two side filtering plates, the two slidingplates and the two support bases are respectively and symmetrically arranged about the central plate.

Description

technical field [0001] The invention relates to a municipal sludge solid impurity separation mechanism. Background technique [0002] At present, the treatment of urban sludge has to go through the processes of impurity separation, dehydration and collection. With the economic development and the improvement of people's awareness of environmental protection, the treated sludge is now reused, such as making building materials and fertilizers. With the development of science and technology, what's more, the extraction technology of heavy metals in sludge is also changing with each passing day. However, due to the high water content in the sludge, the sludge is usually dehydrated and concentrated before the municipal sludge is transported to reduce the weight of the sludge, improve the efficiency of transportation, and reduce the transportation cost. However, urban sludge contains a large amount of impurities, which mainly include plastic bags, melon seed shells, vegetable lea...

AI Technical Summary

Problems solved by technology

However, urban sludge contains a large amount of impurities, which mainly include plastic bags, melon seed shells, vegetable leaves, waste paper, large sand particles, etc., which bring great inconvenience to dehydration and concentration, and often lead to sludge treatment if not treated. Blockage of pipes, pumps, etc. in the system will affect the sludge treatment speed and damage equipment
