Water distribution weir plate device

Abstract

The invention discloses a water distribution weir plate device which comprises a plate body. The section of the plate body is U-shaped; a plurality of water filtering groove openings are formed in anupper edge of a side plate of the plate body, reinforcing cross beams are arranged on opposite side faces in the plate body at equal intervals, a protruding block is arranged on a U-shaped face of oneend of the plate body, a groove is formed in a U-shaped face of another end of the plate body, a mounting hole is formed in a side face of one end of the plate body, and a connecting piece is arranged at a side of another end. A plurality of supporting legs are movably arranged at a bottom of the plate body, a flow velocity module is arranged on a bottom surface in the plate body, and the flow velocity module can transmit data to a terminal. The invention discloses a water distribution weir plate device. The plate body can be spliced end to end and can be flexibly spliced and used according to the area of a sedimentation tank, the plate bodies are repeatedly used, production raw materials are saved, the supporting legs play a role in supporting the middles of the plate bodies and preventthe plate bodies from sinking, the supporting legs have different lengths and are suitable for sedimentation tanks with different depths, and a filtering plate prevents large blocks from entering a next procedure.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a water distribution weir plate device. Background technique [0002] In the process of sewage treatment, it is necessary to put the sewage that has been treated for the first time into the sedimentation tank for sedimentation, so that the flocs, sludge and large particles in it will sink to the bottom, and then the clear water in the upper layer will be drawn out, usually using a weir plate, which will be Several water weir plates are set above the sedimentation tank. When the first treated water is injected into the sedimentation tank, the water level of the sedimented water in the sedimentation tank rises, and the uppermost clear water passes through the water weir plate, flows through the water weir plate and enters the lower part of the sedimentation tank. In the first process, the existing water weir plate is usually welded to form a certain length, and then passes t...

[0002] In the process of sewage treatment, it is necessary to put the sewage that has been treated for the first time into the sedimentation tank for sedimentation, so that the flocs, sludge and large particles in it will sink to the bottom, and then the clear water in the upper layer will be drawn out, usually using a weir plate, which will be Several water weir plates are set above the sedimentation tank. When the initial treated water is injected into the sedimentation tank, the water level of the sedimented water in the sedimentation tank rises, and the uppermost clear water passes through the water weir plate and flows into the lower water weir plate. In the first process, the existing water weir plate is usually welded to form a certain length, and then passes through the partition wall of the sedimentation tank to be erected on the sedimentation tank. There is no support column in the middle of the longer water weir plate. , the center of the water weir plate is easy to sink, changing the clear water path, easy to form a short flow, affecting the final clean water quality, and the water weir plate is welded, when the size of the sedimentation tank changes, the water weir plate can only be cut, Or re-weld, waste materials, the existing water weir plate inner wall does not have special anti-corrosion materials, clean water flows for a long time, it is easy to make the inner test plate adhere to microorganisms
