Overlapped spiral type sludge dewatering machine

Abstract

The invention relates to the field of sludge treatment equipment and in particular relates to an overlapped spiral type sludge dewatering machine. The overlapped spiral type sludge dewatering machineis characterized by comprising a rack and overlapped spiral type sludge dewatering devices, wherein the rack comprises a bottom plate and a baffle plate and two sides of the baffle plate are hinged with the bottom plate; a plurality of overlapped spiral type sludge dewatering devices are arranged on the bottom plate in parallel; each overlapped spiral type sludge dewatering device comprises a rotary shaft which is arranged along the bottom plate and is driven by a motor, and an overlapped spiral mechanism which sleeves the rotary shaft and rotates along the rotary shaft; a feeding opening is formed above a downstream end of each overlapped spiral mechanism and a filtrate outlet is formed below the downstream end of each overlapped spiral mechanism; filtrate grooves, which are communicatedwith one another and are obliquely arranged, are fixedly mounted below the filtrate outlets of the plurality of overlapped spiral type sludge dewatering devices; a mud discharging cavity communicatedwith each overlapped spiral mechanism is formed in an upstream end of each overlapped spiral mechanism; each mud discharging cavity is provided with a mud discharging opening; a belt conveyor is mounted below the plurality of mud discharging openings. The device provided by the invention has the advantages of low cost, small land occupation and high efficiency and can realize centralized treatmentof sludge and filtrate.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a screw stacking sludge dehydrator. Background technique [0002] Sewage treatment plants will produce sludge during the process of sewage treatment. Since there is still a large amount of water in the sludge, if it is not treated or treated improperly and discharged, it is not conducive to the incineration of sludge, and will give Water and air cause secondary pollution. The existing screw stacking sludge dewatering machines generally only have one set of screw stacking dewatering devices, and the production efficiency is relatively low. If a large amount of sludge needs to be processed, multiple sludge dewatering machines must be purchased, which not only costs high, but also occupies an area of It is relatively large, and it is difficult to realize the centralized treatment of filtrate and sludge.
