Description

A Radial Settling Tank

technical field

The utility model relates to the field of sewage treatment equipment, in particular to a radial flow sedimentation tank.

Background technique

The radial flow sedimentation tank is a common equipment for large and medium-sized sewage treatment plants. The suspended matter in the sewage gradually settles and enters the sludge hopper along the slope of the bottom of the tank. Purpose.

Since a large amount of suspended matter in sewage is deposited on the bottom of the tank to form thick sludge, all radial flow sedimentation tanks need to have the function of sludge discharge on the bottom. The mechanical mud discharge mechanism of the sedimentation tank in the prior art is often relatively complicated. The use of a large truss and a mud scraper at the bottom to rotate and scrape mud on the bottom surface has the following disadvantages:

1) The large in-line truss and the mud scraper whose length is similar to the radius of the pool bottom make the mud scraper cause obvious agitation to the water body when the mud scraper rotates in the pool, affecting the settlement of suspended solids and reducing the purification efficiency. The large-scale mud discharge mechanism not only consumes more materials, resulting in waste of resources and increased costs, but also has a complex and large structure that is difficult to clean, resulting in difficulties in maintenance.

2) The existing mud scraper can only scrape up the sludge at the bottom of the pool, and the sludge will naturally fall into the mud bucket in the center along with the slope by gravity. Since the inclination angle of the slope is relatively gentle, it is difficult to achieve rapid sludge removal only by gravity. Concentration makes the sludge discharge mechanism operate for a long time, continuously agitating the water body affects sedimentation, and wastes electric energy.

3) The motor part of the existing mud discharge mechanism is generally installed at the center above the sedimentation tank, exposed to the external environment all the year round, aging and damaged quickly.

4) Regardless of whether the water enters from the center or the edge, the agitation of the water body caused by the sedimentation tank when entering the water is always a common problem in this field. The prior art still can't solve this problem well.
