Embodiment 1

[0033] A hydraulic automatic control interception sewage well. The brick well body 2 is divided into a filter well chamber, an interception well chamber and a water outlet well chamber according to the water flow sequence. A grille 21 is arranged between the filter well chamber and the interception well chamber. An overflow weir 22 is set between the water outlet well chambers; a sewage interceptor 4 is arranged at the lower part of the interception well chamber to communicate with the outside, and a sewage interceptor valve is installed at the mouth of the sewage interception pipe; a water outlet 3 is installed in the water outlet well chamber, and an anti-backflow clapper is installed at the 3 outlets Door 31.

[0034] The valve body 41 of the sewage intercepting valve is provided with a rotating shaft, and a steel wire is used to connect the valve plate under the rotating shaft. The rotating shaft realizes the up and down movement of the valve plate 42 by winding and pulling...

Embodiment 2

[0040] The structure is basically the same as that of Example 1, the difference is that the well body is made of concrete, the hydraulic buoy can be replaced by a hydraulic buoy, the rotating shaft and the valve plate 42 are connected by gear transmission, and the sundries lifting plate is replaced by a nylon rope filter.

Embodiment 3

[0042] The structure is basically the same as that of Embodiment 1, the difference is that: the well body is made of cast iron, and the rotating shaft and the valve plate 42 are connected by gear chain transmission.

Abstract

The invention discloses a hydraulic automatic control sewage intercepting well. The well is characterized in that a well body is divided into a filtering well chamber, an intercepting well chamber anda water outlet well chamber according to the water flowing sequence, wherein a grating is arranged between the filtering well chamber and the intercepting well chamber, and an overflow weir is arranged between the intercepting well chamber and the water outlet well chamber; a sewage intercepting pipe is arranged at the lower part of the intercepting well chamber and is communicated with the outside, and a sewage intercepting valve is arranged at an opening of the sewage intercepting pipe; a water outlet is formed in the water outlet well chamber, and an anti-backflow flap valve is arranged atthe water outlet. The sewage intercepting well device is suitable for small-flow pollutant intercepting of confluence pipes in villages and towns, the automatic operation is achieved, the construction investment is saved, the operation cost is low, construction and maintenance are convenient, the interception amount of combined sewage can be automatically controlled, and the situation that the load of a subsequent pipeline is too large and overload operation of a sewage treatment plant is caused due to an excessively large pollutant intercepting amount is avoided.

Description

technical field [0001] The invention relates to a municipal drainage device, in particular to a hydraulic automatic control interception sewage well. Background technique [0002] Due to the popularization of China's township sewage treatment projects, the demand for sewage interception wells suitable for the effective collection of my country's township sewage is becoming more and more urgent. At present, the common problems are the low effective collection rate of township sewage, the influent concentration of township sewage is generally low, the inflow in rainy season exceeds the design scale, and the energy consumption of sewage plants is large. After analyzing the impact of the problems in the installation of sewage collection pipe network interception wells More importantly, if the collection of sewage can be effectively controlled (reducing the interception of low-concentration confluent rainwater and preventing backflow of river water), significant benefits will be ...
