Duckweed isolating type quantitative floating water outlet device

Abstract

The invention relates to the technical field of unpowered drainage devices for wastewater treatment sedimentation tanks, in particular to a duckweed isolating type quantitative floating water outlet device. The device comprises an upper slide way fixing frame, inductance approach switches, float bowls, water distribution weir plates, a drainage tank, float bowl adjusting devices, drainage telescopic pipes, a water collecting pipe, an electrically-operated valve, a sedimentation tank, limiters, support slide ways and drainage tank guide sleeves. The device is characterized in that the drainage tank guide sleeves are welded with the drainage tank and are sleeved on the support slide ways, the drainage telescopic pipes are connected on the water collecting pipe by welding, the water distribution weir plates are symmetrically mounted on two sides of a drainage tank end plate, the float bowl adjusting devices are welded in the middles of two ends of the float bowls, and the float bowls can move up and down by rotating float bowl adjusting bolts so that quantitative drainage is achieved. The electrically-operated valve is mounted on an outer pipe portion of the water collecting pipe extending out of the sedimentation tank, and drainage automatically stops when the sedimentation tank reaches an upper limit water level and a lower limit water level by the aid of the upper limiter, the lower limiter and the inductance approach switches. The duckweed isolating type quantitative floating water outlet device is free from powered energy consumption, low in equipment investment and operating maintenance cost and high in operating stability.

Description

technical field [0001] The duckweed-separated quantitative floating water discharge device of the present invention relates to a non-powered drainage device for a sedimentation tank for primary sewage treatment. Background technique [0002] In the existing industrial sewage treatment system, the drainage of the sedimentation tank for the primary treatment of the sewage involved in the primary treatment adopts the submersible pump for drainage. Due to the high consumption of power energy and the high cost of use, the maintenance cost of the submersible pump is also high. The submersible pump discharges the water at the bottom of the sedimentation tank for primary sewage treatment. Since the submersible pump is a suction drainage, it is easy to suck and discharge the dirt that has settled at the bottom into the next-level sewage treatment tank, which will increase the next-level treatment accordingly. facility load.
