Abstract

The present invention relates to a water-supply and sewerage system for building and is characterized by that on the basis of original water-supply system of building the washing water is passed through washing water drain pipe and secondary utilization water-collecting pipe, and flowed into secondary utilization water storage tank, them passed through the secondary utilization water-supply pipe connected with secondary utilization water storage tank and control device to provide water for toilet bowl, and the sewage of toilet is passed through the original blowdown pipe and discharged from building. The overflowing secondary utilization water can be passed through the overflow pipe mounted on the secondary water storage tank and fed into next-story secondary utilization water storage tank or fed into external blowdown pipe. Said invention can fully utilize washing water, and possesses good water-saving effect.

Description

Water saving building water supply and drainage system

The present invention relates to a kind of supply and drain water system of building, it is a kind of water-saving supply and drain water system of slurry of second use building.

At present, supply and drain water system in the building is that drinking water and washroom water are clean water, cause a large amount of wastes of water resource like this, particularly the waste of water resource is not only caused in the lack of water city, causes the inconvenience of resident living but also the water supply department timesharing is supplied water.

The object of the present invention is to provide a kind of water saving building water supply and drainage system, to reach the purpose that using water wisely makes things convenient for resident living with the slurry second use.

Purpose of the present invention can realize by following measure: water saving building water supply and drainage system, by the outside water supply system in the building, compositions such as the discharge system of sewage, it is that slurry in building flows into the washing gutter after the second use collection pipe flows in the second use storage tank, a second use feed pipe that is communicated with it is arranged at the bottom of second use storage tank, water in the second use feed pipe can be washed by water to the lavatory pan that is positioned at building by control device, the sewage that lavatory pan is discharged is discharged outside the building by the drainage pipe that is provided with in the building, and bleed off pipe is equipped with on the top of second use storage tank.

Purpose of the present invention can also realize by following measure:

Each layer at building all is equipped with a second use storage tank total or a plurality of minutes families, the top of second use storage tank be equipped with one be connected with each washing gutter in this layer or respectively with each independently the unit with wash the second use collection pipe that gutter is connected, the water of the bleed off pipe overflow of the second use storage tank on upper strata flows into down in the second use storage tank of one deck successively, and the undermost bleed off pipe of building leads to the drainage system outside the building.

The washing gutter of each floor all imports a total collection pipe inflow that is provided with on the building by the second use collection pipe with the supporting setting of this floor belowstairs second use storage tank is set in the building, the water-raising system that water in the second use storage tank is made up of lift pump and second use lifting pipe is raised storage tank on the second use that is positioned on the roof, on the second use bottom of storage tank have with each layer in the second use pipeline that supplies water and to be connected, strainer all is equipped with in the feed water inlet of supplying water for the second use feed pipe on second use in storage tank and the second use storage tank and the water inlet of second use lifting pipe, water storage tank water level control device on the second use that electrically connects with lift pump is being housed on the storage tank on the second use, and the bleed off pipe that storage tank top is adorned on the second use is connected with total collection pipe.

Every 3～5 layers of facing mutually of building are a water saving unit, be provided with the second use storage tank in this water saving unit bottom, the second use storage tank on each top is that storage tank and its bleed off pipe flow in the second use storage tank of bottom on the second use with respect to the second use storage tank of its underpart, the second use storage tank is arranged in the washroom of building or sun terrace is gone up or the building outside body of wall on, also the second use storage tank of last layer can be arranged on down the washroom of one deck or the top of sun terrace.

The present invention compared with prior art has the conserve water resource, slurry is recycled and can be guaranteed the advantage that the washroom lavatory pan washes at any time in the area of Timing water supply.

Accompanying drawing drawing of the present invention is described as follows:

Fig. 1 is the principle schematic that layering is provided with the water saving building water supply and drainage system of second use storage tank

Fig. 2 is the principle schematic that the water saving building water supply and drainage system of second use storage tank is set downstairs

Below in conjunction with accompanying drawing embodiments of the invention are further described: shown in Figure 1: water saving building water supply and drainage system, it is one four floor room, its water system adopts prior art, the foul water system of washroom lavatory pan also adopts prior art, capacity that a bottom is higher than lavatory pan feed pipe or feed tank be set be 1 cubic metre second use storage tank 4 at one jiao of place of the washroom of the unit in 3～1 layers of left side, slurry in the 4th floor room flows into washing gutter 1 after second use collection pipe 7 flows in the second use storage tank 4, a second use feed pipe 2 that is communicated with it is arranged at the bottom of second use storage tank 4, water in the second use feed pipe 2 can be to lavatory pan 3 baths that are positioned at each unit of building by pipeline and control device, the sewage that lavatory pan 3 is discharged is discharged outside the building by the drainage pipe that is provided with in the building, bleed off pipe 5 is equipped with on the top of second use storage tank 4, the water of bleed off pipe 5 overflows on second use storage tank 4 tops on upper strata feeds down in the second use storage tank 4 of one deck successively, and the undermost bleed off pipe 5 of building leads to the drainage system outside the building.

Shown in Figure 2: it is one four floor room, its clean water water system and foul water system adopt prior art, slurry inflow washing gutter 1 back in each floor room imports a total collection pipe inflow that is provided with in the buildings by the second use collection pipe 7 with the supporting setting of this layer and is provided with in the belowstairs second use storage tank 4, the water-raising system that the water of second use storage tank 4 is made up of lift pump 8 and the second use lifting pipe 11 that is provided with in the building is raised storage tank 10 on the second use that is positioned on the roof, on the second use bottom of storage tank 10 have with each layer in second use 2 pipelines that are connected that supply water, the strainer 9 that cover and the filter screen of its water inlet are made all is equipped with in the feed water inlet of supplying water for second use feed pipe 2 on second use in storage tank 10 and the second use storage tank 4 and the water inlet of second use lifting pipe 11, at the water-level control apparatus 12 that storage tank 10 on the second use that electrically connects with lift pump 8 is housed on the storage tank on the second use 10, lift pump 8 quits work when the water level of storage tank on the second use 10 reaches critical height, lift pump 8 is started working when the water level of storage tank on the second use 10 hangs down to critical groundwater table, and the bleed off pipe 5 that storage tank 10 tops are adorned on the second use is connected with total collection pipe.
