Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a Lamela sedimentation tank. Background Art

[0002] The Lanmeila inclined plate sedimentation tank is a common sewage sedimentation facility. The Lanmeila inclined plate sedimentation tank refers to a sedimentation tank with an inclined plate in the sedimentation area. It is an inclined plate assembly with an inclination angle of 60° installed above the sludge suspension layer, so that the suspended matter, solid matter in the raw water or flocs formed after the addition of flocculants accumulate on the bottom surface of the inclined plate to form a thin mud layer, and rely on gravity to slide back to the sludge suspension layer, and then sink into the mud collecting bucket, and then discharged into the sludge pool through the mud discharge pipe for further treatment or comprehensive utilization. The upper clear liquid gradually rises to the water collecting pipe and is gradually discharged, which can be directly discharged or reused.

[0003] The Chinese Patent Database has disclosed a patent entitled "A Inclined Plate Sedimentation Tank", application number: 202320215340.0, application date: 2023.02.14. The specification of the present invention discloses in paragraph

[0063] that: wherein, a connecting frame 316 is arranged on the top of the first scraper 305, a second spring 317 is arranged between the connecting frame 316 and the bottom rod 304, a locking bolt 318 is arranged on the bottom rod 304, and a gap is left between the bottom end of the locking bolt 318 and the first scraper 305; the present application also adopts a soft connection method for the connection of the first scraper 305, that is, a plurality of second springs 317 are used to ensure that the first scraper 305 can swing to a certain extent, so that the first scraper 305 can fit the bottom of the sedimentation tank 1 to ensure the cleaning effect; the present application also provides a locking bolt 318, which is movably matched with the connecting frame 316. When the first scraper 305 is displaced, it can be resisted by the locking bolt 318 to avoid excessive displacement of the first scraper 305, which can be limited and adjusted by the locking bolt 318.

[0004] The disadvantage of the structure disclosed in the above patent is that the second spring has no waterproof measures, and the sewage has strong corrosion ability. There are many impurities in the sewage and they basically settle at the bottom of the pool. On the one hand, the impurities are easy to adhere to the surface of the second spring, and on the other hand, they are easy to scratch the second spring. Therefore, the spring is easy to rust, which will affect the working condition of the first scraper. Utility Model Content
