Hydraulic self control flow converging pipe network flow cut-off control well

Abstract

The invention discloses a hydraulic self control flow converging pipe network flow cut-off control well, which comprises a well body, wherein a rain and sewage flow converging water inlet pipe is arranged at the left end of the well body, the right end of the well body is provided with a water outlet pipe, a primary rain overflow weir, a slag blocking floating tube and a multi-stage adjustable overflow plate are sequentially arranged on the flow passage of the well body from the left side to the right side, a sewage flow cut-off pipe is arranged at the bottom of the side wall of the well body between the rain and sewage flow converging water inlet pipe and the primary rain overflow weir, a floating tube flow cut-off check valve is arranged on the sewage flow cut-off pipe, a primary rain flow cut-off pipe is arranged at the bottom of the side wall of the well body arranged between the primary rain flow overflow weir and the multi-stage adjustable overflow plate, and a flow cut-off check valve is arranged on the primary rain flow cut-off pipe. The floating tube flow cut-off check valve is arranged at an inlet of the sewage flow cut-off pipe, in addition, the flow cut-off check valve is arranged at the inlet of the primary rain flow cut-off pipe so that the flow rate of the flow cut-off sewage and the primary rain can be controlled, and in addition, the reverse flow of the sewage and the primary rain can be prevented; the slag blocking floating tube is used for blocking slag, so the blocking phenomenon is avoided, the adjustable height of the discharge water level can be realized through the multi-stage adjustable overflow plate, further, the effective separation of the primary rain is realized, and the primary rain can be conveyed to sewage treatment plants to the maximum after the flow cut-off operation.

Description

technical field [0001] The invention relates to a drainage pipe network system, in particular to a hydraulic self-controlled combined pipe network interception well. Background technique [0002] The rain at the initial stage of rainfall is referred to as primary rain. In the early stage of rainfall, the rainwater dissolves a large amount of acid gas in the air, automobile exhaust, factory exhaust gas and other polluting gases. etc., causing the initial rain to contain a large amount of pollutants such as organic matter, pathogens, heavy metals, grease, and suspended solids. Therefore, the pollution degree of the initial rain is relatively high, usually exceeding that of ordinary urban sewage. If the early rainwater is directly discharged into natural The water body will cause very serious pollution to the water body, so the first rain needs to be treated. At present, the interception pipe network system is usually used to intercept the first rainwater to the sewage pipe an...

Problems solved by technology

At present, the interception pipe network system is usually used to intercept the initial rainwater to the sewage pipe and send it to the sewage treatment plant for purification treatment. However, the pollution degree of the rainwater in the later period of the rainfall is relatively light. After pretreatment to intercept the suspended solids and solid particles in the water, Directly discharged into natural water bodies, but the current initial rain interception facilities have the following disadvantages: 1) The structure of the interception equipment is complex and the operation is difficult; 2) The filter equipment is easy to block during the pretreatment of the later rainwater before discharge; 3) The drainage water level Fixed and not adjustable
