Problems solved by technology

[0002] Traditional sludge dewatering generally uses a plate-and-frame filter press, but the plate-and-frame filter press cannot achieve continuous sludge dehydration, and the plate-and-frame filter press has a long single pressing cycle, and the unloading process is cumbersome. Cleaning and maintenance are time-consuming and laborious, and the operation efficiency is low

Abstract

The invention belongs to the technical field of sludge treatment and specifically relates to a sludge dewatering system. The sludge dewatering system comprises a feeding pipe, a dewatering mechanism,a liquid discharging pipeline and a slag discharging device, wherein the feeding pipe communicates with a feeding port of the dewatering mechanism, the dewatering mechanism is used for squeezing sludge, the liquid discharging pipeline communicates with a liquid discharging hole of the dewatering mechanism, and the slag discharging device is located at a slag discharging port of the dewatering mechanism and collects dewatered sludge. Continuous extrusion of sludge in a shell is achieved through revolution and rotation of an arc triangle, so continuous dehydration operation of the sludge is achieved, and the dehydration efficiency of the sludge is improved. The slag discharging device is arranged to be of a movable structure, a material guiding groove moves to a position below the slag discharging hole and is used for guiding sludge to fall towards a conveying belt during slag discharging; and when slag discharging is not conducted, the material guiding groove is removed from the position below the slag discharging hole, and overflowing water drips into a water receiving groove, so secondary mixing of the overflowing water, water and the sludge is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge dewatering system. Background technique [0002] Traditional sludge dewatering generally uses a plate-and-frame filter press, but the plate-and-frame filter press cannot achieve continuous sludge dehydration, and the plate-and-frame filter press has a long single pressing cycle, and the unloading process is cumbersome. Cleaning and maintenance are time-consuming and laborious, and the operation efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a sludge dewatering system capable of realizing continuous sludge dewatering. [0004] The technical scheme that the present invention takes is specifically as follows: [0005] A sludge dewatering system, comprising a feed pipe, a dehydration mechanism, a liquid discharge pipeline and a slag discharge device, the feed pipe communicates with the feed inl...
