Central transmission mud scraper

Abstract

The invention relates to a central transmission mud scraper. The central transmission mud scraper comprises a base, a transmission shaft, a main scraping arm, a driving device and a gear case, wherein the base is mounted above the sludge discharge opening of a sedimentation tank; the transmission shaft is vertically mounted on the base; the upper end of the transmission shaft is connected with the gear case; the driving device is mounted on the gear case and connected with the gear case; the center of the main scraping arm is fixedly mounted at the lower end of the transmission shaft; a plurality of main mud scrapers are distributed at the bottom of the main scraping arm; four-bar linkage mechanisms are arranged at the two ends of the main scraping arm respectively and distributed on the two sides of the main scraping arm; each four-bar linkage mechanism is divided into an upper layer and a lower layer; the other end of each four-bar linkage mechanism is connected with a corner scraping arm; a corner mud scraper is arranged at the bottom of the corner scraping arm; a depended wheel is mounted at the tail end of the corner scraping arm. The four-bar linkage mechanisms are additionally arranged at the two ends of the main scraping arm, so that settling sludge at four corners, except for settling sludge at periphery, can be effectively scraped away, flow crashes from four corners are fully used for producing turbulences, coagulation reaction is strengthened, aqueous separation effect is improved, and the quality of yielding water is improved obviously.

Description

technical field [0001] The invention relates to a mud scraper, in particular to a central transmission mud scraper, and belongs to the technical field of environmental protection equipment. Background technique [0002] The sedimentation tank is a structure that uses sedimentation to remove suspended solids in the water. The sewage is distributed through the central tube and then flows to the surrounding overflow tank. With the decrease of the flow rate, the suspended solids in the sewage are separated and settled at the bottom of the pond, and the center is reused. After the sludge is scraped and collected by the transmission scraper into the central sludge collecting tank, it is discharged from the sludge pipe by the hydrostatic pressure. For the circular sedimentation tank, the central transmission scraper can better handle the sludge at the bottom of the sedimentation tank, but for the square sedimentation tank, the current central transmission sludge scraper cannot effe...

AI Technical Summary

Problems solved by technology

For circular sedimentation tanks, the center-driven sludge scraper can better treat the sludge at the bottom of the sedimentation tank, but for square sedimentation tanks, the current central-drive sludge scraper cannot effectively remove the sludge at the four corners of the sedimentation tank , thus affecting the working effect of the sedimentation tank
