Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sedimentation tank for preventing flocculation and deposition. Background Art

[0002] A sedimentation tank is a water purification device that uses gravity sedimentation to settle and separate suspended matter or flocculants in the water. During use, flocculants are usually added after the sewage enters to improve the flocculation effect of the sewage.

[0003] At present, most of the sedimentation tanks on the market have relatively flat bottoms, which are prone to flocculation and deposition. It is inconvenient to clean thoroughly. The deposited floccules will undergo chemical and biological reactions, and over time they will form dead sludge floating on the water surface, seriously affecting the effluent quality of the high-efficiency sedimentation tank. Therefore, a sedimentation tank that prevents flocculation and deposition is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a sedimentation tank for preventing flocculation and sedimentation, so as to solve the problems raised in the above-mentioned background technology.

[0012] As a preferred solution, the interception plate and the right-angle plate rotate clockwise with the rotation axis as the center. When the interception plate and the guide plate are in contact, the right-angle plate is parallel to the ground, and an angle of 60° is formed between the interception plate and the guide plate.

[0013] As a preferred solution, the angle between the top edge of the collecting bucket and the horizontal line is between 30-60°.
