Description

A rain and sewage diversion well suitable for building confluence drainage

technical field

The invention relates to a rain and sewage diversion well, in particular to a rain and sewage diversion well suitable for building confluence drainage.

Background technique

In the building drainage system, roof rainwater and domestic wastewater in the building are often combined into a drainage riser. Such combined drainage directly enters the municipal rainwater pipeline, and will eventually flow to natural water bodies, causing environmental pollution; if all of it is connected to the municipal sewage pipe network, it will increase the burden on the sewage treatment plant.

For the above-mentioned combined drainage pipes in the building, carry out rain and sewage diversion transformation. When the indoor pipeline cannot be transformed into rain and sewage diversion, a rain and sewage diversion well can be set on the outdoor drainage pipe. At present, the commonly used rain and sewage diversion wells are well room, water inlet pipe, sewage pipe and rainwater pipe. The water inlet pipe, sewage pipe and rainwater pipe are arranged on the wall of the well chamber. The rainwater pipe is set higher than the sewage pipe. When there is only sewage, the water inlet pipe enters. In the well room, due to the limited amount of sewage, the drainage pipe quickly drains the sewage into the sewage system; when the amount of rainwater is large, the sewage pipe is not discharged in time, the water level rises, and is discharged from the rainwater pipe into the rainwater system. At this time, there is still a large amount of rainwater Enter the sewage pipe, and at the same time when the amount of rainwater is small, all the rainwater has a sewage pipe to enter the sewage system. Therefore, the existing rain and sewage diversion wells are not effective.

SUMMARY OF THE INVENTION

In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a rainwater and sewage diversion well that can be used for combined drainage of buildings.

In order to solve the above technical problems, the present invention provides a rainwater and sewage diversion well suitable for combined drainage of buildings, including a water inlet pipe, a well chamber, a sewage pipe and a rainwater pipe. The well chamber is provided with a partition, the partition divides the well chamber into a sewage chamber and a rainwater chamber, the water inlet pipe passes through the well chamber wall of the sewage chamber, the outlet of the water inlet pipe is opposite to the partition plate, and the partition plate is provided with a water inlet pipe. The hole corresponding to the outlet, the sewage pipe is arranged on the wall of the well chamber of the sewage chamber, the rainwater pipe is arranged on the wall of the well chamber of the rainwater chamber, and both the sewage pipe and the rainwater pipe are lower than the hole.

Further, the above-mentioned holes and the outlet of the water inlet pipe are on the same horizontal line, which is convenient for installation. As long as the potential energy of rainwater on the roof is large enough, the rainwater column of the outlet of the drainage pipe passes through the holes.

Further, the above-mentioned water inlet pipe is provided with a pipeline energy dissipation device, and the energy dissipation device is located in the attached well close to the well chamber. The energy dissipation device is mainly used to eliminate the kinetic energy of part of the sewage, so that the horizontal flow rate of the sewage water column at the outlet of the water inlet pipe is reduced. It falls down quickly and does not pass through the hole, which can reduce the distance between the partition and the water inlet pipe, which can greatly reduce the space of the diverter well.

Compared with the prior art, the beneficial effect of the present invention is that the initial potential energy of rainwater is much larger than that of sewage. No matter the size of the rainwater, after the potential energy of the rainwater is converted into kinetic energy, it can pass through the holes on the separator in the present invention. Enter the rainwater chamber and discharge into the rainwater system; the sewage passes through the energy dissipation device to reduce the kinetic energy of the sewage, so that the sewage cannot pass through the holes, stay in the sewage chamber, and discharge into the sewage system to achieve the purpose of rain and sewage diversion. At the same time, the space of the diverter well is reduced and the cost is reduced.

Detailed ways

The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings, referring to Figures 1-4.

A rainwater and sewage diversion well suitable for building confluence drainage includes a water inlet pipe 100 , a well chamber 200 , a sewage pipe 300 and a rainwater pipe 400 . The well chamber 200 is provided with a partition plate 210, the partition plate 210 divides the well chamber 200 into a sewage chamber 220 and a rainwater chamber 230, the water inlet pipe 100 passes through the well chamber wall of the sewage chamber 220, and the outlet of the water inlet pipe 100 is connected to the partition plate 210. On the other hand, the partition plate 210 is provided with holes 211 corresponding to the outlet of the water inlet pipe 100, the sewage pipe 300 is provided on the wall of the well chamber 200 of the sewage chamber 220, the rainwater pipe 400 is provided on the wall of the well chamber 200 of the rainwater chamber 230, and the sewage pipe 220 and the rainwater pipe 230 are both lower than the hole 211 .

The hole 211 and the outlet of the water inlet pipe 100 are on the same horizontal line.

The water inlet pipe 100 is provided with a pipeline energy dissipation device 110 , and the energy dissipation device 110 is located in the attached well 240 close to the well chamber 200 .

The following describes the use process of the present invention in detail.

When the sewage collection device 500 in the building discharges the sewage into the confluence riser 120, and then flows to the horizontal inlet pipe 100, the potential energy of the sewage is converted into kinetic energy, and part of the kinetic energy of the sewage is reduced through the pipeline energy dissipation device 110, thereby reducing the intake of sewage. The horizontal flow rate at the outlet of the water pipe 100 prolongs the residence time of the sewage water column 130 in the sewage chamber 220 ; under the action of gravity, the sewage water column 130 generates a downward acceleration, so that the sewage water column 130 slopes downward and falls, impacting the bottom of the hole 211 On the separator 210 or the bottom of the sewage chamber 220, the distance between the separator 210 and the water inlet pipe 100 can be reduced, thereby greatly reducing the space of the shunt well and reducing the cost; the sewage is isolated in the well chamber 200 by the separator 210 In the sewage chamber 220, it is discharged from the sewage pipe 300 in the lower part.

After the rainwater is collected by the roof rainwater collection device 140, regardless of the size of the rainwater, it enters the merging riser 120, and then flows to the horizontal water inlet pipe 100. Since the initial potential energy of the rainwater is larger than the initial potential energy of the sewage, the rainwater is transformed by the potential energy. The kinetic energy of the water is also large, and the partial kinetic energy of reducing the rainwater through the pipeline energy dissipation device 110 is limited, so that the horizontal flow rate of the rainwater at the outlet of the water inlet pipe 100 is limited, and the horizontal flow rate of the rainwater column 150 at the outlet of the water inlet pipe 100 is still relatively large. Therefore, The rainwater water column 150 has a short residence time in the well chamber 200, the downward flow velocity is small, and basically maintains a horizontal flow direction, passes through the holes 211 on the partition plate 210, impacts on the well wall of the rainwater chamber 230, and falls into the rainwater The inside of the chamber 230; the rainwater is isolated in the rainwater chamber 230 by the partition plate 210 in the well chamber 200, and is discharged by the rainwater pipe 400 at the lower part.

The above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore: all equivalent changes made according to the structure, shape and principle of the present invention shall be covered by the protection of the present invention. within the range.
