Description

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 combined flow drainage.

Background

In a building drainage system, roof rainwater and domestic wastewater in a building are often combined into a drainage vertical pipe. The combined drainage directly enters a municipal rainwater pipeline and finally flows to a natural water body to cause environmental pollution; if all the sewage is connected into a municipal sewage network, the burden of a sewage treatment plant is increased.

Aiming at the confluence drain pipe in the building, rain and sewage diversion transformation is carried out. When indoor pipeline can't carry out the reposition of redundant personnel of rain and sewage and reform transform, can set up the reposition of redundant personnel of rain and sewage well on outdoor drain pipe. At present, a common rainwater and sewage diversion well comprises a well chamber, a water inlet pipe, a sewage pipe and a rainwater pipe, wherein the water inlet pipe, the sewage pipe and the rainwater pipe are arranged on the wall of the well chamber; when the rainwater quantity is large, the sewage pipe discharges untimely, the water level rises, and the rainwater pipe discharges and enters the rainwater system, at the moment, a large amount of rainwater still enters the sewage pipe, and when the rainwater quantity is small, all rainwater has the sewage pipe to enter the sewage system. Therefore, the existing rain and sewage diversion well has poor effect.

Disclosure of Invention

Aiming at the prior art, the invention aims to provide a rainwater and sewage diversion well which can be used for combined drainage of buildings.

In order to solve the technical problem, the invention discloses a rainwater and sewage separating well suitable for combined drainage of buildings. Be provided with the baffle in the well room, the baffle is divided into sewage room and rainwater room with the well room, and the inlet tube passes the well room wall of sewage room, and the inlet tube export is relative with the baffle, is provided with the hole corresponding with the inlet tube export on the baffle, and the sewage pipe sets up on the well room wall of sewage room, and the rainwater pipe is provided with on the well room wall of rainwater room, and sewage pipe and rainwater pipe all are less than the hole.

Furthermore, the holes and the outlet of the water inlet pipe are positioned on the same horizontal line, so that the installation is convenient, and as long as the roof rainwater potential energy is large enough, the rainwater water column at the outlet of the drain pipe penetrates through the holes.

Furthermore, the pipeline energy dissipater is arranged on the water inlet pipe, is located in the attached well close to the well chamber and is mainly used for eliminating the kinetic energy of partial sewage, so that the horizontal flow velocity of a sewage water column at the outlet of the water inlet pipe is reduced, the sewage water column is rapidly inclined downwards and falls, the sewage water column cannot penetrate through the hole, the distance between the partition plate and the water inlet pipe can be reduced, and the space of the flow dividing well can be greatly reduced.

Compared with the prior art, the invention has the beneficial effects that: the rainwater has the potential energy which is much larger than that of the sewage at first, and the potential energy of the rainwater can penetrate through the holes on the partition plate in the invention after being converted into kinetic energy no matter the size of the rainwater, and then enters the rainwater chamber and is discharged into a rainwater system; the sewage passes through the energy dissipation device, so that the kinetic energy of the sewage is reduced, and the sewage cannot pass through the hole, stays in the sewage chamber and is discharged into the sewage system, and the aim of distributing rain and sewage is fulfilled. Meanwhile, the space of the flow dividing well is reduced, and the cost is reduced.

Detailed Description

The invention will now be further described in the following with reference to the accompanying drawings, in which reference is made to figures 1 to 4, in which embodiments of the invention are shown.

A rain and sewage diversion well suitable for building combined drainage comprises 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 210, the partition 210 divides the well chamber 200 into a sewage chamber 220 and a rainwater chamber 230, the water inlet pipe 100 penetrates through the wall of the well chamber of the sewage chamber 220, the outlet of the water inlet pipe 100 is opposite to the partition 210, the partition 210 is provided with a hole 211 corresponding to the outlet of the water inlet pipe 100, the sewage pipe 300 is arranged on the wall of the well chamber 200 of the sewage chamber 220, the rainwater pipe 400 is arranged on the wall of the well chamber 200 of the rainwater chamber 230, and both the sewage pipe 220 and the rainwater pipe 230 are lower than the hole 211.

The holes 211 are located on the same horizontal line as the outlet of the inlet pipe 100.

The water inlet pipe 100 is provided with a pipe energy dissipater 110, and the energy dissipater 110 is located in an additional well 240 close to the well chamber 200.

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

When the sewage collecting device 500 in the building discharges the sewage into the confluence vertical pipe 120 and then flows into the horizontal water inlet pipe 100, the potential energy of the sewage is converted into kinetic energy, and partial kinetic energy of the sewage is reduced through the pipeline energy dissipation device 110, so that the horizontal flow velocity at the outlet of the water inlet pipe 100 is reduced, and the retention time of the sewage water column 130 in the sewage chamber 220 is prolonged; under the action of gravity, the sewage water column 130 generates downward acceleration, so that the sewage water column 130 downwards inclines and falls down to impact on the partition plate 210 below the hole 211 or the bottom of the sewage chamber 220, and thus the distance between the partition plate 210 and the water inlet pipe 100 can be reduced, the space of a flow dividing well can be greatly reduced, and the manufacturing cost can be reduced; the sewage is separated in the sewage chamber 220 by the partition 210 in the well chamber 200 and discharged through the lower sewage pipe 300.

After rainwater is collected by the roof rainwater collection device 140, regardless of the size of the rainwater, the rainwater enters the confluence vertical pipe 120 and then flows into the horizontal water inlet pipe 100, because the initial potential energy of the rainwater is larger than the initial potential energy of the sewage, the kinetic energy of the rainwater converted from the potential energy is also large, and the part of kinetic energy for reducing the rainwater by 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 large, therefore, the retention time of the rainwater column 150 in the well 200 is short, the downward flow rate is small, the horizontal flow direction is basically kept, the rainwater column 150 passes through the hole 211 on the partition plate 210, impacts the well wall of the; the rainwater is separated in the rainwater chamber 230 by the partition 210 in the well 200 and discharged through the rainwater pipe 400 at the lower portion.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
