The utility model aims to solve the technical problem that a building rain and sewage separator is provided, can be when large-traffic rainwater, the self-closing domestic sewage export flows into rainwater pipeline with the rainwater, and when low discharge domestic sewage, the export of automatically opening domestic sewage is with domestic sewage drainage into the sewage pipe.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a building rain and sewage separator, includes box, top cap, inlet tube, rainwater outlet pipe, sewage outlet pipe, its characterized in that: the water inlet pipe is communicated with the filtering tank, a water storage tank is arranged below the filtering tank, and the water storage tank is divided into a first water storage area, a second water storage area and a third water storage area by a first partition plate and a second partition plate; the bottoms of the first partition plate and the second partition plate are respectively provided with a water through hole, the second partition plate is provided with a lever rotating shaft, a floating ball is arranged in the second water storage area, the top of the floating ball is hinged with one end of the lever through a straight rod, and the other end of the lever is connected with a cover plate arranged at the inlet of a sewage water outlet pipe through a chain; the pipe diameter of the rainwater outlet pipe is far larger than that of the sewage outlet pipe; the height of the sewage outlet pipe is lower than that of the rainwater outlet pipe.
Furthermore, a water bridge is arranged between the first isolation plate and the second isolation plate.
The cross-sectional area of the passage of the water passing bridge is far larger than the cross-sectional areas of the water passing holes at the bottoms of the first partition plate and the second partition plate.
Furthermore, the inlet of the sewage outlet pipe is an inclined opening.
Further, a handle net basket is arranged in the filter tank.
The pipe diameter of the rainwater outlet pipe is not smaller than that of the water inlet pipe.
Compared with the prior art, the utility model discloses a no circuit mode carries out the dirty separation of automatic rain, through the water storage volume in judging the storage tank, automatic switch-over rivers passageway. The device has the advantages of no need of manual intervention, no need of detection equipment, no need of power consumption, simplicity and convenience, and capability of better realizing the separation and drainage of the sewage and rainwater mixing pipe of the building. The problems that rainwater flows backwards to the water outlet of the water pool, overflows and the like in rainstorm are solved.
When ordinary domestic sewage flows in, the water yield is less, and the floater is located the second tank bottom, and the lever upwards pulls up the apron of sewage outlet pipe, exposes sewage outlet pipe. The inlet water enters the water storage tank through the filter tank, enters the third water storage area through the water passing holes in the first isolation plate and the second isolation plate, and directly flows out through the sewage outlet pipe; when facing rainstorm, discharge is great, and the water yield in the reservoir is more, and the sewage outlet pipe is too late to discharge the water in the reservoir. At the moment, the floating ball in the second water storage area floats, the chain descends under the action of the lever, the cover plate above the sewage outlet pipe automatically descends, the sewage outlet pipe is gradually closed, the water level in the water storage tank is further caused to rise, and the water outlet pipe flows out until the rainwater passes through a higher position.

Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
As shown in figures 1 to 4, the rain and sewage separator for buildings of the utility model comprises a box body, a top cover, a water inlet pipe, a rain water outlet pipe and a sewage water outlet pipe. The automatic domestic sewage and rainwater judgment system is used in a building water pipeline system and is provided with a filter tank, domestic sewage and rainwater can be automatically judged according to water flow in a water pipe, and therefore water outlet is automatically divided into a sewage outlet pipe and a rainwater outlet pipe to be discharged. The domestic sewage has small water flow and automatically flows out of the sewage outlet pipe, and the water flow is large during rainstorm,
the box body is internally provided with a water inlet pipe which is communicated with a filtering tank, and the filtering tank is internally provided with a handle basket. A water storage tank is arranged below the filtering tank and is divided into a first water storage area, a second water storage area and a third water storage area by a first partition plate and a second partition plate;
the bottom of the first partition board and the bottom of the second partition board are respectively provided with a water passing hole, the second partition board is provided with a lever rotating shaft, a floating ball is arranged in the second water storage area, the top of the floating ball is hinged with one end of the lever through a straight rod, and the other end of the lever is connected with a cover plate arranged at the inlet of a sewage outlet pipe through a chain. The inlet of the sewage outlet pipe is an inclined opening, and the cover plate automatically covers the inlet of the sewage outlet pipe after the chain of the cover plate is put down.
The pipe diameter of the rainwater outlet pipe is far larger than that of the sewage outlet pipe. The height of the sewage outlet pipe is lower than that of the rainwater outlet pipe.
The utility model discloses still be provided with the water bridge between first division board and second division board, the water bridge highly is higher than the water hole of crossing of first division board and second division board bottom to the passageway sectional area of crossing the water bridge is far greater than the sectional area of crossing the water hole that first baffle separates and second division board bottom.
Under the conventional state, the water that the inlet tube flowed in filters the back through handle basket, gets into the first tank of below, in the water hole of crossing through first division board and second division board bottom progressively enters into second tank and third tank. At the moment, the floating ball is positioned at the bottom of the second water storage tank, the lever pulls up the cover plate of the sewage outlet pipe through the chain, and water flows out through the sewage outlet pipe.
When large-flow water inflow such as rainstorm occurs, the inflow water enters the first, second and third water storage tanks after being filtered, the sewage outlet pipe does not reach the discharge water storage, the water level of the water storage tank rises, the floating ball in the second water storage tank floats, the lever puts down the lock chain, the cover plate covers the sewage outlet under the action of gravity, and the water is shunted to the rainwater outlet and is discharged.
In order to deal with the situation that a large amount of water in the first water storage tank flows in, the water through holes are not ready to drain, and the water bridge starts to drain water from the first water storage tank to the third water storage tank quickly. The flow speed of water in the rain and sewage separator is accelerated.
