Problems solved by technology

[0002] Sedimentation tanks are widely used in wastewater treatment. Sedimentation tanks are a structure that uses sedimentation to remove suspended solids in water and equipment for purifying water quality. The bottom of traditional sedimentation tanks is a horizontal floor. When the sludge sedimentation thickness at the bottom of the sedimentation tank reaches the cleaning standard, a mud scraping device is erected by erecting a support frame above the sedimentation tank to scrape the settled sludge from the bottom of the sedimentation tank, and then carry out transfer treatment , the operation is troublesome, and at the same time, the effect of sludge cleaning is not good, and more sludge is often left at the bottom of the pool, which makes sludge cleaning more frequent, troublesome to clean, short cleaning cycle, and inconvenient to operate

Abstract

The invention discloses a sewage sedimentation device convenient for sludge discharge. The device comprises a tank, a water inlet pipe, a stirring plate and a mixer shaft. the bottom of the tank is provided with a conical cavity shaped as an inverted cone structure. The inner wall of the conical cavity is abutted against symmetrically-arranged scraper plates. The bottom of the tank is communicatedwith a vertical pipe, inside which a spiral blanking roller is arranged. the top of the spiral blanking roller is fixedly connected with the scraper plates. Through the tank provided with the conicalcavity, the scraper plates which are abutted against and slidingly connected with the inner wall of the conical cavity and the spiral blanking roller arranged inside the vertical pipe, the settled sludge is efficiently collected and discharged, and it is convenient to clean sludge while obstruction of a sludge discharge pipe is avoided. Through the stirring plate provided with a central pipelineand an overflow orifice, a gear pump and a hollow mixer shaft, efficient and uniform diffusion of a flocculating agent is realized, mixing uniformity and efficiency of the flocculating agent are raised, and sediment generation is accelerated.
