A kind of floating outlet weir gate

Abstract

The invention provides a floating effluent weir gate. The floating effluent weir gate is ingenious in structure, free from power, reliable in action, adapted to water level change, and stable in overflow quantity. The weir gate is arranged at the inner side of a pool water outlet, and comprises a gate frame, a flexile gate panel and a floating assembly; the gate frame is fixed on the inner side wall of the water outlet; the floating assembly is arranged at the inner side of the gate frame, and comprises a pair of guide rails, a pair of buoys and a roller; the guide rails are fixedly connected in the pool in upright and arranged at the outer side of the gate frame; the buoy is movably connected with the guide rail; the roller is movably connected between the pair of buoys through the spindles at two ends; the bottom side of the flexible gate panel is fixedly connected with the lower side at the bottom of the gate frame and upward wrapped on the roller, and the top side is fixedly connected with a balancing weight; and the top edge height of the roller is lower than that of the buoy. The floating effluent weir gate is simple in structure, delicate, practical, convenient and high in reliability.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an automatic lifting weir gate capable of uniformly discharging water with changes in water level. Background technique [0002] In the water treatment industry, according to different water treatment processes, there are generally two ways for the treated water to be discharged out of the pool: continuous drainage and intermittent drainage. Among them, the continuous drainage mostly uses external pipes connected to the weir groove, without control, directly outside Drainage; while intermittent drainage generally requires water to be discharged according to the required flow rate, so a uniform speed drainage device is required to avoid water flow disorder and affect the quality of effluent water. [0003] In existing indirect drainage projects, decanters or weir gates (including cast iron direct-acting weir gates and steel rubber-sealed rotary weir gates) are often used f...

Problems solved by technology

In this patent, the position of the floating tank needs to be adjusted according to the situation, which makes the automatic effect of adjusting the position of the main board of the weir door poor; the sliding connection between the main board of the weir door and the frame of the weir door will wear out after long-term use, reducing the service life and low reliability
