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

Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as Figure 1-11 As shown, a municipal sludge filtration and collection equipment includes an impurity separation device, a sludge supply device for providing sludge to the impurity separation device, and a sludge collection box 1 for collecting the separated sludge.

[0037] The impurity separation device includes a sludge filter mechanism containing sludge and a sludge extruding mechanism that squeezes the sludge filter mechanism, and the sludge filter mechanism and the sludge extruding mechanism are connected by a steel wire rope 2 (such as Figure 1-3 shown). Squeeze the sludge filter mechanism through the sludge extrusion mechanism to quickly separate the impurities in the sludge from the sludge. After the impurities are squ...

Abstract

The invention relates to filtration and collection equipment of municipal sludge. The filtration and collection equipment comprises an impurity separation device, a sludge supply device for supplyingthe sludge to the impurity separation device and a sludge collection tank collecting separated sludge, wherein the impurity separation device comprises a sludge filtration mechanism for accommodatingthe sludge and a sludge extrusion mechanism for extruding the sludge filtration mechanism; the sludge filtration mechanism is connected with the sludge extrusion mechanism through steel wire ropes; the sludge filtration mechanism comprises a center plate, two filtration side plates rotationally arranged on the two sides of the center plate and two slide plates rotationally connected with the two filtration side plates respectively; the two slide plates are slidingly arranged on two support seats respectively; the two filtration side plates, the two slide plates as well as the two support seatsare symmetrically arranged relative to the center plate.

Description

technical field [0001] The invention relates to an urban sludge filtering and collecting equipment, and relates to the technical field of designing sludge treatment equipment. 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 impurit...
