Description

Technical Field

[0001] The utility model relates to the field of sedimentation tanks, in particular to a sedimentation tank with a mud removal function. Background Art

[0002] In the sewage treatment process, the suspended substances in the water are settled through physical or chemical action, and the suspended substances naturally sink and separate from the wastewater, so as to treat the sewage. In the sewage sedimentation process, the bottom and inner wall of the sedimentation tank are easily contaminated with sludge. The Chinese utility model type patent with the public document number: CN219681780U discloses a sedimentation tank with a sludge discharge function. The utility model realizes the inner wall cleaning and sludge recovery of the sedimentation tank, which can not only replace manual cleaning, speed up the cleaning speed, and improve work efficiency, but also can clean the bottom inner wall and the surrounding inner wall of the sedimentation tank at the same time, without omission.

[0003] However, during the sludge removal process of the utility model, the sewage sedimentation treatment needs to be temporarily stopped. During the sludge removal process, when the sewage is still normally precipitating in the sedimentation tank, a large amount of sewage will be pumped out together with the sludge by the sewage pump, resulting in a large amount of sewage waste. In addition, when the lifting impeller rotates in the sewage, the sludge will be redispersed and diffused back into the sewage. Therefore, during the sludge discharge process, the sewage sedimentation needs to be temporarily stopped to avoid interfering with the sludge removal work. However, this delays the sewage sedimentation work and reduces the efficiency of the sewage sedimentation. Utility Model Content

The scraper blade 506 scrapes the upper surface of the fixed cover plate 501 and the inner wall of the sedimentation box 1 to scrape off the sludge, and pushes the sludge from the side of the fixed cover plate 501 into the mud collecting bucket 2 below. When the sludge on the inner wall of the sedimentation box 1 and the fixed cover plate 501 is removed, the reduction motor 509 is turned off, and the scraper frame 505 and the scraper blade 506 are stored in the fixed After the sewage is settled and cleared again, the cylinder 515 is started to move the movable cover 511 downward, and the guide rod 513 moves downward in the guide tube 514. When the movable cover 511 and the fixed cover 501 are closed to each other, the limiting block 512 is stuck on the surface of the fixed cover 501, and the scraper frame 505 is located between the limiting blocks 512. At this time, the movable cover 511 and the fixed cover 501 close the mud collecting bucket 2 to prevent the sewage in the sedimentation tank 1 from entering the mud collecting bucket 2. At this time, the sewage pump 4 is started to extract the sludge in the mud collecting bucket 2, thereby discharging the sludge and performing mud removal.
