Mud scraping device for sedimentation tank of water purification plant

Abstract

The invention discloses a mud scraping device for a sedimentation tank of a water purification plant, and relates to the technical field of sedimentation tank mud scraping. The problem that precipitated mud is not comprehensively collected is solved. The device specifically comprises a handrail, a fixing plate is arranged on the outer wall of the middle of the bottom of the handrail, two mud scraping bridges are arranged on the outer walls of the two sides of the fixing plate correspondingly, two limiting plates are arranged on the outer walls of the two sides of the bottom of each mud scraping bridge correspondingly, a same machine base is arranged on the outer walls of the middles of the bottoms of the two mud scraping bridges correspondingly, and a driving mechanism is arranged in the machine base; and a mud guide mechanism is arranged at the bottom of the machine base, mud scraping mechanisms are arranged below the two mud scraping bridges, and each mud scraping mechanism comprisestwo sets of mounting plates distributed at equal intervals, three or more reinforcing ribs and connecting shafts, two sets of first connecting plates, two sets of second connecting plates, two drossguide plates, two inclined guide plates, three or more fixing blocks and three or more mud scraping plates. According to the invention, the problem of blockage and retention in traditional mud scraping is effectively solved.

Description

technical field [0001] The invention relates to the technical field of mud scraping in sedimentation tanks, in particular to a mud scraping device used in sedimentation tanks of water purification plants. Background technique [0002] The sedimentation process adopts a sedimentation tank, which is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Use the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The sedimentation effect depends on the flow rate of the water in the sedimentation tank and the residence time of the water in the tank. During the use of the sedimentation tank, a large amount of silt will be deposited at the bottom, which needs to be removed regularly. [0003] After retrieval, t...

Problems solved by technology

[0004] Although the overall structure has achieved the work of scraping the sedimentation tank, since the bottom of the sedimentation tank in the figure is a horizontal structure instead of a funnel-shaped structure, during the process of scraping mud with the mud scraper, sedimentation will inevitably accumulate, making a small amount of The problem of sedimentation mud leaking from both sides of the mud inlet, so there is still the problem of incomplete collection of sedimentation mud
