Description

Technical Field

[0001] This utility model relates to the field of sludge discharge devices, specifically to a sludge discharge device for a thickening tank. Background Technology

[0002] Sludge removal from thickening tanks is primarily achieved through physical or mechanical methods. Physical methods include gravity sludge removal, which utilizes the density difference between solid particles in the sludge and water, allowing the sludge to settle naturally under gravity, with the concentrated sludge periodically discharged from the bottom through a sludge discharge pipe. Mechanical methods use equipment such as sludge scrapers to collect the sludge to the center and discharge it, while the clear water above drains out from the surrounding area. However, the inner bottom of the thickening tank is conical, and the sludge discharge trough at the center is also conical; excessive settling sludge can cause blockage of the trough. Therefore, those skilled in the art have provided a sludge removal device for thickening tanks to solve the problems mentioned in the background art. Utility Model Content
