Centrally-driven flow stabilization mud scraper

Abstract

The invention relates to a centrally-driven flow stabilization mud scraper. The flow stabilization mud scraper is arranged on a sedimentation tank in a spanned mode. The mud scraper includes a slag discharge hopper, a slag skimming device, a mud scraping mechanism, a flow stabilization cylinder, a central transmission frame, a driving mechanism, a maintenance bridge, a plurality of scum baffles and a plurality of water outlet weir plates, wherein the plurality of scum baffles and the plurality of water outlet weir plates are arranged around the wall of the sedimentation tank, a sludge discharge port is arranged at the lower part of the central transmission frame, the bottom of the sedimentation tank is provided with a water inlet, the slag discharge hopper is arranged at the upper part ofthe sedimentation tank, the slag discharge hopper is connected with a slag discharging pipe to communicate with the outside of the sedimentation tank, the slag skimming device is arranged on the surface of the water flow of the sedimentation tank, the lower part is connected to the mud scraping mechanism, the driving mechanism controls the central transmission frame to stably rotate, the mud scraping mechanism includes scraper arms and a scraper plate, and the scraper plate is connected to the lower parts of the scraper arms to cling to the bottom of the sedimentation tank. The centrally-driven flow stabilization mud scraper has the advantages of simple structure, large transmission torque, stable and balanced operation, good flow stabilization effects, good sludge discharge effects, prevention of scum accumulation and long service life.

Description

technical field [0001] The invention relates to a mud scraping device for an industrial environmental protection sedimentation tank, in particular to a center-driven steady flow mud scraper. Background technique [0002] The central drive pendant type sludge scraper is widely used in the circular settling tank of the sewage treatment plant of the water supply project, and scrapes the sludge settled at the bottom of the tank to the sludge collection pit for further treatment. In the prior art, the mud scraper is located in the center of the sedimentation tank, and the central transmission shaft is driven by the driving device. At the same time, the mud scraper arm connected to the central transmission shaft starts to work in the circumferential direction, and then the bottom of the sedimentation tank The sludge is scraped to the sludge collection tank in the center of the tank body, and discharged out of the tank through the sludge discharge pipeline with a pump or by self-pr...

AI Technical Summary

Problems solved by technology

During the working process, because the driving device directly drives the central transmission shaft to work, the torque it bears is relatively large, and long-term use is likely to cause poor stability and reduce the service life of the equipment
