Chongqing Wolik Environmental Protection Equipment Co., Ltd. specializes in manufacturing peripheral transmission mud scraper thickener manufacturers
The scraper is mainly used in large-scale circular sedimentation tanks in urban sewage treatment plants, waterworks and industrial wastewater treatment, to remove the sludge settling on the bottom of the pond and skimming the scum on the pond surface.
The mud scraper is composed of a driving device, a working bridge, a main mud scraping device, an auxiliary mud scraping device, a center turntable, a skimming device, an overflow weir plate and a slag blocking plate, and a current collecting device. In general, a deflector is also required for the effluent sedimentation tank around the central inlet.
The driving device drives the scraper to rotate around the center of the sedimentation tank. After the raw water is settled in the sedimentation tank, the supernatant is discharged from the overflow weir plate, and the sludge settled at the bottom of the tank is slowly pushed by the logarithmic spiral curve scraper. The ground flows along the bottom of the pond into the central mud collection tank and is discharged through a drainage pipe. At the same time, the pool scum is concentrated in the area between the scum scraper and the scum baffle. When the working bridge passes the scum discharge cylinder floating on the pool surface, the scum discharge cylinder is pressed below the liquid surface and the scum passes through. The discharge tube is discharged out of the pool.
; 1. The mud scraper adopts the logarithmic spiral curve form and uses rubber wheels to support walking along the bottom of the pool. The mud scraping effect is good, the requirements on the bottom of the pool are low, and the adaptability is good ;
; 2. In addition to the main mud scraping device, a unique auxiliary mud scraping device is also installed to enable the half-bridge mud scraper to function as a full-bridge mud scraper ;
; 3. The working bridge adopts a truss structure, and the steel deck is laid on the bridge deck, which has high strength, light weight and low energy consumption ;
; 4.The driving wheel is a solid rubber wheel, no track is required, the structure is simple, and the installation is convenient ;
5. The underwater parts are made of stainless steel, and the water parts are made of carbon steel and hot-dip galvanized, with good corrosion resistance and long service life.
, 刮板桁架和刮泥板装置围绕中心支座缓慢旋转 , 将沉淀于池底的污泥向中心集泥坑刮集 , 通过池内的水位压力差将泥斗内的污泥排出池外 , 同时撇渣板将浮渣撒至浮渣斗内 , 经浮渣斗自动冲水或自流将浮渣排出池外。 Driven by the power unit, the full-bridge peripheral drive scraper slowly rotates the scraper truss and the scraper device around the center support to scrape the sludge that settles at the bottom of the pond to the central sludge pit , and passes the water pressure in the pond. The sludge in the mud hopper is discharged out of the pool at the same time . At the same time , the scum slag board scatters the scum into the scum hopper, and the scum is automatically flushed by the scum hopper or self-flow to discharge the scum out of the pool.
