Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and specifically relates to a sludge storage tank used for sludge treatment. Background Art

[0002] Sludge treatment is the process of reducing, stabilizing and rendering sludge harmless. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must have sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal has become the most complex and costly part of sewage treatment system operation.

[0003] A Chinese patent with application number CN202321898242.8 discloses a sludge storage tank for sludge treatment, including a screw pump, a tank body, and a pushing mechanism. The screw pump is arranged at the bottom of the tank body, a top cover is arranged on the top of the tank body, a discharge pipe is arranged on one side of the end surface of the top cover, and a discharge hole is arranged on the other side of the end surface of the top cover. Connecting blocks are symmetrically arranged on the stirring shaft, and a push rod is slidably connected in the connecting rod. A scraper plate is arranged between the upper and lower adjacent push rods, and the scraper plate is abutted against the inner wall of the tank body. A spiral blade is arranged on the stirring shaft.

[0004] The above scheme drives the scraper plate to rotate through the stirring shaft, so that the scraper plate scrapes and cleans the inner wall of the tank. However, in actual use, the scraper plate fits tightly with the tank body under the action of the spring. When the stirring shaft rotates, the scraper plate and the inner wall of the tank are continuously rubbed, which can easily cause the scraper plate to wear faster. Moreover, when the stirring rod quickly stirs the sludge, the scraper plate and the inner wall of the tank accelerate friction and heat up, which can easily cause the sludge on the scraper plate to dry, adhere, and be difficult to clean.

[0005] In view of this, the present utility model is proposed. Utility Model Content
