Problems solved by technology
When the residence time of the sewage in the sedimentation tank meets the process requirements, the sludge at the bottom of the sedimentation tank needs to be cleaned. The existing device uses strips to rotate and scrape the sludge at the bottom of the tank, and then the sludge scraping effect There is only a "scraping" action on the surface, and it does not realize the discharge and transfer of the scraped sludge, that is, the consequence of using the device is that the sludge will naturally fall off and gather at the sewage outlet, which will cause the sludge to be blocked in the sewage outlet. At the same time, if the device rotates in the sedimentation tank for too long, the clear water in the sedimentation tank will be polluted by the dispersed sludge. In summary, there are many defects in the existing device

The invention discloses a sludge scraping device of a sewage sedimentation tank. The sludge scraping device comprises the sedimentation tank, wherein the opening part of the sedimentation tank is provided with a pair of bottom plates, one end, away from the sedimentation tank, of one bottom plate is fixedly connected with a motor, one side, away from the motor, of the bottom plate is fixedly connected with four rollers in rectangular distribution, the opening part of the sedimentation tank is fixedly connected with a track, the four rollers are all arranged on the track in a sliding way, roller shafts are fixedly connected between rotating shafts of the pairs of rollers, chain disks fixedly sleeve the roller shafts, a chain disk also fixedly sleeves the output end of the motor, the two chain disks are connected with each other through a chain, and the sides, away from the sedimentation tank, of the pair of bottom plates are fixedly connected with supports. The sludge scraping device disclosed by the invention is novel in structure, ensures the effect of sludge cleaning at the bottom of the entire sedimentation tank by utilizing the rotation of a pair of sludge scraping rods at thebottom of the sedimentation tank, and achieves the effects of breaking up sludge and discharging and transferring sludge by virtue of spiral paddles.
Description
technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a mud scraping device for a sewage sedimentation tank. Background technique [0002] Sedimentation tank 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. When the residence time of the sewage in the sedimentation tank meets the process requirements, the sludge at the bottom of the sedimentation tank needs to be cleaned. The existing device uses strips to rotate and scrape the sludge at the bottom of the tank, and then the sludge scraping effect There is only a "scraping" action on the surface, and it does not realize the discharge and transfer of the scraped sludge, that is, the consequence of using the device is that the sludge will naturally fall off and gather at the sewage...
