Background

The general drainage pipes are classified into a rainwater pipe, a sewage pipe, a confluence pipe and the like.

The rainwater pipe vertically arranged outdoors can also be called as a downpipe, is specially used for collecting rainwater on a roof, and discharges the rainwater to a rainwater pipe network on the ground, so that the rainwater can be finally discharged into a river channel.

The sewage pipe is used for discharging sewage, is provided with a vertical pipe and a horizontal pipe, and can be used for discharging domestic sewage, industrial sewage and the like. The sewage pipe is generally prohibited from directly discharging into the river channel, and is required to be conveyed to a sewage treatment plant through a sewage pipe network for treatment and then discharged.

The confluence pipe is a pipeline for draining and discharging rainwater and sewage together, and rainwater and sewage are not shunted, so that the later water treatment capacity is large if the rainwater and sewage are not shunted, and the rainwater and sewage are shunted and discharged if the rainwater and sewage are not treated and the environmental protection performance is not good.

In real life, the downpipe and the sewer of a residential building are separately arranged. However, there is a phenomenon that the sewage pipes are connected to the downpipe and directly discharged into the river, which causes deterioration of the water quality of the river. This phenomenon is urgently required to be improved.

Disclosure of Invention

The purpose of the invention is as follows:

the problem that the traditional downpipe is not suitable for being discharged with a sewage pipe shared pipeline or rain and sewage cannot be split when the traditional downpipe is discharged in a shared mode is solved, and the building vertical pipe rain and sewage splitter is simple and convenient to connect and install, capable of sharing vertical pipes and easy to split.

The technical scheme is as follows:

the invention relates to a rain and sewage diverter for a building vertical pipe (buildings in the text generally refer to various houses such as buildings, single houses and storehouses, the vertical pipe in the text comprises various water pipes which are vertically arranged and slightly inclined with a vertical line), and the rain and sewage diverter is provided with an outer pipe and a bundle pipe which is connected with the inner wall of the outer pipe and is arranged in the interior of the outer pipe (or the outer pipe and the bundle pipe are integrally manufactured).

The pipe wall of the outer pipe above the beam pipe (or higher than the beam pipe outlet by a proper height) is provided with a rainwater overflow port (connected with an overflow pipe and communicated with a rainwater pipe network) or a maintenance port (for opening and dredging when being blocked, and an external maintenance cover or a plug end is sealed).

The beam tube is funnel-shaped and has a bell mouth (round table shape or step shape) and a straight-line tube section. The upper end of the beam tube is seamlessly connected with the inner wall of the outer tube, and a limit ring (or a limit flange-salient point) can be arranged between the horn mouth of the beam tube and the inner wall of the outer tube, so that the beam tube is convenient to position.

The direct drainage pipe section with the pipe diameter smaller than the inner diameter of the outer pipe is arranged below the horn mouth of the bundle pipe, and the horn mouth is convenient for accommodating the falling water above the horn mouth; the straight-line pipe section narrows the water path, and the water flow is limited.

The upper end of the existing rainwater downpipe is connected with the rainwater ditch edge of the roof of the house, the middle section of part of the rainwater pipe receives a sewage pipe which is connected by a building resident in a private pulling and disorderly way, and the lower end of the rainwater downpipe is communicated with a rainwater pipe network (or a rainwater well).

When this rain and sewage shunt used, carried out appropriate transformation to the pipe in the water, directly communicate the outer tube upper end interface and the pipe in the water lower extreme of rain and sewage shunt (or be connected through accessories such as beam section, pipe strap), the mouth is arranged directly to the sewage of the outer tube lower extreme of rain and sewage shunt inserts municipal sewer pipe network (or bilge well).

When the water quantity in the downpipe is small, generally sewage discharged in the rainless or light rain state is connected into a sewage pipe network through the outlet of the bundle pipe and the sewage straight discharge port at the lower end of the outer pipe.

When the amount of water in the downpipe is large, the downpipe is generally rain water in heavy rain. The pipe diameter of the bundle pipe is small, so that rainwater cannot flow down quickly, only a small amount of rainwater is directly discharged into a sewage pipe network, and the small amount of directly discharged rainwater can have the function of flushing the sewage pipe network; and a large amount of rainwater which does not reach the descending of the beam pipe flows back or overflows, flows out through a rainwater overflow port on the pipe wall of the outer pipe and flows into the rainwater pipe network.

When a large amount of rainwater is mixed with sewage for mixed flow, the sewage is doped with solid sewage more and has higher density, and can be deposited at the lower end of water flow and is difficult to flow backwards. Most of sewage is discharged to the sewage straight discharge port through the bundle pipe outlet and flows into the sewage pipe network. Most of the rainwater in the mixed flow does not flow away directly but flows into the rainwater pipe network through the rainwater overflow port.

The drainage process can basically ensure that the distribution of rain and sewage is realized, and the automatic distribution does not need manual intervention.

In the present invention, it is preferable that:

the straight-line section of beam pipe can have the straight-line section that the second grade or tertiary shrink step by step, further narrows down, has both increased the velocity of flow, plays the effect that vigorously erodees sewage pipe network, reduces the straight-line of rainwater again, lets more rainwater overflows, reduces sewage pipe network's load and the sewage treatment capacity in later stage.

And a support screen plate can be arranged between the straight-line pipe section and the outer pipe, so that the fixing firmness of the bundle pipe is improved.

The lower part of the straight-line pipe section can be connected with an extension section in the shape of an inverted bell mouth as a drainage wall, so that the noise of sewage discharge can be reduced, and dirt can not be stored and taken in between the outer pipe and the bundle pipe.

The inner wall of the straight-line pipe section can also be provided with even vertical grooves (the grooves are opposite to the grooves) which are symmetrically arranged and are sunken towards the direction of the outer pipe, so that the inner diameter of the position is locally increased (the cross section area of the straight-line pipe section is still very small compared with that of the outer pipe at the moment, and the straight-line water flow can be designed and controlled), thereby facilitating the discharge of sewage with larger scale in the sewage and preventing the straight-line pipe section from being blocked.

In addition, assume that: the diameter of the outer pipe is D, the diameter of the straight-line pipe section is D (when a vertical groove is formed, the diameter of the narrowest part is formed), the height of the lower section of the outer pipe (from the joint of the beam pipe to the sewage straight discharge port) is H, and the height of the beam pipe is H. According to experience, the discharge amount of domestic sewage is 1/4-1/36 of medium rain and rain, and D = 2-6D is preferred; d is too large, rainwater flows into a sewage pipe network too much, and the sewage treatment capacity is increased; d is too small, large scale dirt is difficult to flow out through the bundle tube.

Has the advantages that:

when the rainwater and sewage diversion system is used, the upper end is directly connected to a downpipe or a drain pipe of a building, the lower end is connected to a municipal sewage pipe network, the overflow port is connected to a municipal rainwater pipe network, and rainwater and sewage diversion is automatically realized in ground management; the connection is very convenient, the ground operation can be carried out, a riser, a horizontal pipeline or a cut-off wall does not need to be newly added, excessive building and pipe network transformation do not need to be carried out, the new building or the building rescue transformation can be carried out, and the investment and use cost is very low.

The original building water leakage pipe is not allowed to be connected with a sewage discharge branch in a private way in terms of building decoration specifications, and the private connection change of building residents can be no longer limited after the current diverter provided by the invention is used (of course, the current construction specifications are forbidden and not suggested). After the invention is adopted, building residents can be connected with a sewage pipe on the downpipe in a private mode, and can be connected with the existing sewage pipe network and the existing rainwater pipe network nearby to realize automatic rainwater and sewage diversion after sewage is mixed and flows into the rainwater pipe.

The invention does not depend on the control of pipes such as valves and the like, automatically realizes the distribution of rain and sewage, and has good separation effect and high distribution efficiency.

The pipe fitting is simple to manage and maintain at the later stage, and when the pipeline is blocked, the maintenance cover or the plug of the maintenance opening can be detached for dredging. Although the diameter of the beam tube is small, the tube is short, and the beam tube is easy to dredge quickly. Meanwhile, the rainwater overflow port of the invention is higher than the sewage straight discharge port, and the pipe diameter of the beam pipe is small, thus effectively avoiding the unfavorable situation that sewage flows backwards to pollute the rainwater pipe network and the surrounding environment of the building.

The number of buildings, especially residential buildings is large, and the old downpipe generally has the condition of mixed flow of rainwater and sewage. By popularization and application of the invention, the social problem that mixed flow sewage directly beats rivers through the downpipe to pollute the water body can be well solved, and the environmental protection benefit is obvious.

Moreover, the invention can be produced, popularized and applied in large scale and batch by a common injection molding machine and a simple injection mold, and has remarkable economic benefit.
