House roof sewage filtering and separating system

Technical Field

The utility model relates to a building drainage facility technical field, concretely relates to house roof sewage filtration piece-rate system.

Background

Aiming at some buildings with few floors and low floors, such as villas, rural self-built houses and the like, because the buildings are not tall, the top of the building is easy to accumulate some sundries such as leaves, dust and the like, when a roof drainage system of the building is designed, a floor drain is usually arranged in front of a downpipe at the top of the building for filtering, the sundries such as the leaves, the dust and the like are blocked by a filter screen, but only the sundries are temporary and cannot really treat the sundries falling on the roof, the sundries such as the leaves, the dust and the like can be collected at a filter screen of a downpipe opening along with rainwater and water falling on the top of the building, the throughput of the downpipe is reduced after the filter screen is arranged, a large amount of sundries are accumulated at the filter screen, the downpipe opening is easy to be blocked and unsmooth drainage is easy to cause even long-term water accumulation and water seepage and the like at the top of the building. In the current practical life, the floor drain filter screen in front of the downpipe of many buildings is basically blocked, and is especially more serious in rural self-building houses and villas. Many residents are reluctant to clean sundries such as leaves, dust and the like in front of the filter screen on the roof, and the main reasons are that the roof is unsafe and troublesome to use, the blocking frequency is high, and time and labor are wasted.

A technical method for rapidly, simply and conveniently realizing the treatment of the sundries on the roof of the low-rise building is urgently needed to be provided.

Detailed Description

In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1:

as shown in fig. 1 to 3, a house roof sewage filtering and separating system comprises a roof sewer pipe 1 with a pipe orifice arranged on a roof 11, wherein the roof sewer pipe 1 has an upper orifice, namely a water falling orifice arranged on the roof 11, which is opened without placing a filter screen.

The roof sewer pipe 1 is provided with a valve 2, the inventor preferably cuts off the roof sewer pipe 1 at a height which is 1.2 meters away from the ground and is convenient for people to operate during the implementation process, and the valve 2 is installed, and the valve 2 is preferably a ball valve.

A rain and sewage separator 4 is arranged at the lower side of a pipe orifice at the lower end of a sewer pipe 1 of a roof, the rain and sewage separator 4 is connected to a wall through a screw or supported by a support rod, a strip-shaped filter screen 3 is obliquely arranged in the rain and sewage separator, the strip-shaped filter screen 3 is a straight plate or an arc-shaped plate, please refer to fig. 4 and 5, the strip-shaped filter screen 3 generally tends to have an angle of not 45 degrees, and the angle is too large to be beneficial to filtering leaves and impurities;

strip filter screen 3 goes up to open along the long direction parallel of board has a plurality of bar filtration pore 301, and in this embodiment, the inventor finds through many times that the dirty separation effect of the shaped plate that has certain radian is comparatively good, and debris such as leaves that drop on arc lath filter screen 3 spend the lowest department that is provided with strip filter screen 3 to one side more easily because the impact of whereabouts rivers, and can bear bigger water pressure.

It has clean dirty mouthful 5 to open on dirty separator 4 of rain corresponding to bar filter screen 3 incline direction, and clean dirty mouthful 5 lower extreme is higher than the lowest of bar filter screen 3 or is parallel with the lowest of bar filter screen 3, and the debris that drop on bar filter screen 3 come the water punching press through the top, can slowly pile up in clean dirty mouthful 5 departments at last, as long as can be with in the garbage bin with long-pending sediment clearance with hand or some gadgets. The normal work of dirty separator 4 of rainwater can not be influenced even when the clearance is untimely because bar filter screen 3 slope design, and be the design of bar filtration pore 301 above that, or, the design of the parallel of the minimum of 5 lower extremes in the mouth of decontaminating and bar filter screen 3, long-pending sediment is piled up certain height and can be rolled automatically and fall to ground, of course the inventor provides the design of a structure is retrieved in the area in the embodiment later. So as to prevent the falling ground from secondary pollution after being blown away by wind.

When a user observes that the water quantity of the roof sewer pipe 1 above the rain and sewage separator 4 is small, the valve 2 can be closed, the valve 2 can be quickly opened when the water column height of two meters or three meters is estimated to be accumulated in front of the valve 2, higher negative pressure can be generated in the roof sewer pipe 1 at this time, generally, the blocked leaves and sundries in the roof sewer pipe 1 can be pumped down, and if the number of the leaves in the ditch of the roof 11 is large, the repeated pumping is needed for several times, so that the problem of blocking of the roof sewer pipe 1 is basically solved. The diameter of the roof sewer pipe 1 can be properly increased in the newly built house, and the possibility of blockage is further reduced.

The rain and sewage separator 4 is communicated with a sewer pipe 6, the water pipe 6 is arranged at the bottom of the rain and sewage separator 4, the sewer pipe 6 is communicated with a building drainage system, and the rain and sewage separator 4 is communicated with the sewer pipe 6 through a water bucket 702.

Example 2

As shown in fig. 6, the present embodiment is different from embodiment 1 in that a downpipe housing 701 is installed at a lower end nozzle of the roof sewer pipe 1, and the downpipe housing 701 is connected with the rain and sewage separator 4. The sealing performance is better, and the falling water is not easy to splash everywhere.

Example 3

As shown in fig. 7 and 8, the present embodiment is different from embodiment 2 in that the present embodiment further comprises a dirt collecting tank 8, the dirt collecting tank 8 is arranged below the dirt removing opening 5 outside the rain and sewage separator 4, and the lower end of the dirt removing opening 5 is parallel to the lowest position of the strip-shaped filter screen 3.

A reticular leaking frame 9 is arranged in the dirt accumulation groove 8, the reticular leaking frame 9 is detachable and can be directly placed in the dirt accumulation groove 8, the bottom of the dirt accumulation groove 8 is communicated with a return pipe 10, and the other end of the return pipe 10 is communicated with the sewer pipe 6.

Sundries on the inclined strip-shaped filter screen 3 slide into the net-shaped leaking frame 9 in the dirt collecting groove 8 finally due to the impulsive force of water flow, and rainwater in the sundries after standing enters the sewer pipe 6 through the return pipe 10.

The present invention has been described in detail with reference to the specific and preferred embodiments, but it should be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and any modifications, equivalents and the like made within the spirit and principle of the present invention should be included within the scope of the present invention.
