A non-power-limited flow-limiting intelligent interception well with a clapboard slag-retaining device

Abstract

The invention relates to an unpowered current-limiting intelligent intercepting well with a partition board dreg retaining device.The intelligent intercepting well comprises a well body, a sewage inlet pipe, an intercepting sewage pipe and an overflow water outlet pipe are arranged on the side wall of the well body in a communicating mode, and a current limiter is arranged in front of the intercepting sewage pipe.The current limiter comprises a hole, a box chamber, a floating ball and a flashboard, the floating ball and the flashboard are arranged in the box chamber.The hole is communicated with the intercepting sewage pipe, a linkage mechanism is arranged between the floating ball and the flashboard, the floating ball ascends or descends to drive the flashboard to descend or ascend, and the partition board dreg retaining device is arranged in front of the overflow water outlet pipe.The partition board dreg retaining device comprises a baffle, an inclined partition board below the baffle, and an overflow weir opposite to the inclined partition board.The intelligent intercepting well can precisely limit flow.Due to the arrangement of the inclined partition board, the efficient solid interception effect is achieved by preventing the horizontal flowing or a suction effect.A control mechanism is arranged in the box chamber, the risk that current limitation of the floating ball fails is avoided, and the current limiter can adapt to smaller well bodies.

Description

technical field [0001] The invention relates to the technical field of interception wells, in particular to an unpowered flow-limiting intelligent interception well with a clapboard slag-retaining device. Background technique [0002] For the combined drainage pipe network or the separate rainwater pipe network, because the mixed sewage or initial rainwater carries a large amount of particulate pollutants from sources such as urban surfaces, roofs, domestic sewage, and pipeline sediments, it is directly discharged without any interception treatment Entering the receiving water body of the city will cause pollution to the receiving water body. Therefore, it is necessary to intercept the combined pipe network or the separate rainwater pipe network, and set a certain interception multiple so that the intercepted sewage or initial rainwater is discharged into the terminal sewage treatment plant, and the water exceeding the interception capacity is discharged into the surface wat...

AI Technical Summary

Problems solved by technology

The traditional interception wells have the following defects: (1) The flow restriction in the interception well is realized by simple rams or restricted pipe diameters, which cannot achieve accurate flow restriction and ensure the designed interception multiple; (2) The traditional baffles cannot The floating matter and solid matter are completely intercepted, and the passing area of ​​the baffle will gradually decrease with the interception of the floating matter, which will eventually cause the blockage of the baffle; Provide direct basis for the design, operation and management of interception wells and pipelines; (4) Simple and extensive, low management level
