Sludge dehydrating device for municipal hydraulic engineering and dehydrating method thereof

Abstract

The invention discloses a sludge dehydrating device for municipal hydraulic engineering. The sludge dehydrating device comprises a main supporting rack. Mounting plates are mounted at the front and back ends of the main supporting rack, a plurality of air cylinders are arranged on the side wall of each mounting plate, two movable grooves are formed in the side wall of each mounting plate, and thetwo movable grooves are formed in parallel up and down. By arranging a lifting plate clamped into a lifting groove, the stirring height of a conditioning tank can be adjusted flexibly, so that a condition of non-uniform stirring is avoided. By arranging a sludge outlet pipe in the middle of a compression paddle, a sludge discharge pipe does not disturb the use of the compression paddle. The end part of the sludge discharge pipe is farther away from the position of a sludge discharge plate, so that a condition of plugging a compression box is unlikely to occur. By arranging a flushing assemblylocated on the side edges of a first filter band and a second filter band, the first filter band and the second filter bank are flushed conveniently, and the flushing assembly can scrape sludge by using a scraper, so that the sludge dehydrating device has various functions.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge dehydration device for municipal water conservancy projects and a dehydration method thereof. Background technique [0002] In municipal engineering, in order to construct water conservancy projects, it is necessary to transfer sludge. In order to facilitate the transfer of sludge, it is necessary to dehydrate the sludge. The dehydration operation of the sludge not only facilitates the transfer of sludge, but also It can also avoid the secondary pollution caused by the natural drying of the sludge. [0003] The patent document whose publication number is CN205774012U discloses a sludge dehydrator, including a dosing device, a dehydration device and a water collection device. The dosing device is connected to the dehydration device. Said water collection device is arranged below the dehydration device, which is convenient to use, but inconvenient to wash, and the dehydrat...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a sludge dewatering device for municipal water conservancy projects and its dewatering method. When stirring, the sludge at the bottom is likely to be insufficiently stirred, which will affect the later dehydration; when the existing sludge dehydration device for municipal water conservancy projects compresses the sludge, the compression box is prone to blockage; the existing The sludge dewatering device used in the municipal water conservancy project is not convenient enough to flush the filter belt of the dewatering device, and it needs to be washed separately when flushing multiple filter belts, resulting in the waste of water resources
