Description

Technical Field

[0001] The utility model belongs to the technical field of water outlet weir plates, in particular to a water outlet weir plate for a mud scraper. Background Art

[0002] A sludge scraper is a machine specially used to remove sludge from a river or sedimentation tank. It is widely used in urban sewage treatment plants, water plants and circular sedimentation tanks in industrial wastewater treatment to remove sludge settled at the bottom of the tank and to skim off scum on the surface of the tank. The outlet weir is a device set at the outlet weir of the filter tank. Its main purpose is to prevent the loss of filter material and adjust the outlet water balance.

[0003] The Chinese patent with application number CN202221791330.3 in the prior art discloses a V-shaped water outlet weir plate and provides the following technical solutions: a V-shaped water outlet weir plate, including a main weir plate, on which a plurality of V-shaped water outlets for water outlet are arranged, the main weir plate is a hollow structure, and the main weir plate is provided with a plurality of auxiliary water outlets between adjacent V-shaped water outlets, and a secondary weir plate for opening and closing the auxiliary water outlet is movably provided inside the main weir plate at each auxiliary water outlet, and has the following technical effects: by adding auxiliary water outlets of adjustable size and cooperating with the V-shaped water outlets, the discharge flow rate can be controlled, and the sediment can be effectively prevented from being carried up due to excessively fast water flow, and by adding a spoiler at the bottom of the main weir plate, the flow direction can be guided when the sediment is carried up, so that it flows to the bottom of the pool and is re-deposited without flowing out with the water flow.

[0004] The outlet weir plate of the existing filter pool is made of carbon steel or plastic and is completely fixed to the support body of the outlet weir. However, this outlet weir plate is fixed and cannot be adjusted. If the water volume in the filter pool changes, such as cleaning the filter pool teeth, it is easy to affect the treatment effect of the filter pool. For this reason, we propose an outlet weir plate for a scraper. Utility Model Content
