Description

Technical Field

[0001] The utility model relates to the technical field of mud discharge, in particular to a mud discharge mechanism of a sedimentation tank. Background Art

[0002] The function of sedimentation tank sludge removal is to remove solid particles in the pool water, prevent them from accumulating at the bottom, reduce water siltation and pollution, and thus keep the water clean. Sedimentation tank sludge removal also helps maintain the fluidity and patency of the water body, ensure the effectiveness of subsequent treatment processes, improve sewage treatment efficiency, and reduce adverse impacts on the environment;

The above patent technology can install the fixing plate and the slide rail on the inner wall of the sewage treatment sedimentation tank through the bolt connection port 1 and the bolt connection port 2, and then the staff starts the motor 2 by adjusting the control switch group, and the motor 2 drives the screw rod to rotate. Because the scraper plate slides on the bottom wall of the sewage treatment sedimentation tank, the slider moves forward and backward along the screw rod under the limiting effect of the bottom wall of the sewage treatment sedimentation tank on the scraper plate, thereby automatically scraping mud, which can save manpower and reduce the discomfort caused by the staff manually cleaning the sludge in the sewage treatment sedimentation tank, and the cleaning is more thorough;

[0034] Among them, two limit rods 14 are fixedly connected inside the sedimentation tank body 1, and the scrapers 11 are slidably connected to the limit rods 14. The above device uses the limit rods 14 to limit the sliding trajectory of the scraper 11 while the scraper 11 moves horizontally to prevent it from detaching.

[0035] Among them, baffles 15 are rotatably connected on both sides of the sedimentation tank body 1, and screws 16 are rotatably connected on one side inside the baffle 15.

[0039] Working principle:

The second motor 13 starts and rotates the reciprocating screw 10 fixedly connected thereto through the output shaft. The scraper 11 is threadedly connected to the reciprocating screw 10, and scrapers 12 are fixed to the bottom of both sides of the scraper 11. As the reciprocating screw 10 rotates, the scraper 11 reciprocates under the sliding of the limit rod 14, and the sludge is scraped from the bottom of the inner wall of the sedimentation tank body 1 to the inside of the transmission groove 2 through the scraper 12. An auger 3 is installed in each transmission groove 2. When the first motor 7 is started, its output shaft is connected to one of the pulleys 4 by rotation. Subsequently, the two pulleys 4 are connected by a transmission belt 5, so that the two augers 3 rotate synchronously. The auger 3 pushes the sludge into the lower mud groove 8 at the bottom of the pool by rotation. After the sludge scraped into the lower mud groove 8 accumulates, the mud storage vehicle 9 can move into position from under the sedimentation tank body 1 to receive the sludge discharged from the lower mud groove 8. Through the linkage and rapid mud discharge, the need for manual intervention and large-scale pool cleaning can be reduced, which not only reduces the frequency and labor cost of pool cleaning, but also reduces the related machinery use and maintenance costs, greatly improving the operation quality and utilization efficiency compared with traditional devices.
