Description

Technical Field

[0001] The utility model relates to the technical field of sewage discharge equipment, in particular to a sediment sludge discharge device for sewage treatment. Background Art

[0002] Sewage treatment is widely used and is increasingly entering the daily lives of ordinary people. Flocculants need to be added during the sewage treatment process to precipitate the sludge in the sewage, thereby achieving sewage treatment.

[0003] A Chinese patent discloses a sludge discharge device for sewage treatment (authorization announcement number CN220546624U). The patented technology includes a sedimentation tank, a stirring unit, a sewage discharge unit and an adjustment unit; the sedimentation tank is a rectangular tank body; the stirring unit includes a fixed plate, a waterproof telescopic rod, a mounting plate, a stirring motor, a U-shaped stirring motor mounting plate, a stirring shaft and a stirring fan blade group. The right end of the lower surface of the fixed plate is fixedly connected to the top of the waterproof telescopic rod, the bottom end of the waterproof telescopic rod is fixedly connected to the right end of the mounting plate, and the two sides of the middle of the upper surface of the mounting plate are respectively fixedly connected to the two ends of the U-shaped stirring motor mounting plate. The sewage discharge unit and the stirring unit are controlled in two dimensions by multiple linear motors, so that the sewage discharge unit and the stirring unit reach various places in the sedimentation tank. The stirring unit stirs the sludge at the bottom of the tank and then discharges the sludge through the sewage pump, which has high efficiency and good sewage discharge effect.

[0004] However, this patent still has some shortcomings. Although it can stir the sludge at the bottom of the sedimentation tank during use, making it easier to discharge the sludge, the stirred sludge tends to float upward, and the sludge is dispersed inside the sedimentation tank, requiring more time to discharge. Therefore, those skilled in the art have provided a sewage treatment sludge discharge device to solve the problems raised in the above background technology. Utility Model Content

[0042] When the auger rod 270 rotates inside the sewage trough 120 , the sludge inside the sewage trough 120 will move outwards driven by the auger rod 270 .

[0043] The scraper 250 is an L-shaped structure, and the bottom end of the scraper 250 is in contact with the bottom end of the sedimentation tank 110;

[0044] Driven by the second electric telescopic rod 240 , the scraper 250 can scrape the sludge at the bottom of the sedimentation tank 110 and scrape it to the top of the sewage trough 120 .

[0045] Use of the sewage discharge assembly 200;

[0046] When it is necessary to discharge the sludge inside the sedimentation tank 110, the first electric telescopic rod 220 is controlled to extend downward, and the extension of the first electric telescopic rod 220 drives the baffle 230 to move downward.
