Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1
As shown in fig. 1 and 3, the building water-saving system takes a five-storey building as an example and comprises three building water-saving devices, wherein each building water-saving device comprises a wastewater collecting pipeline 1, a sedimentation filtering device and a water collecting tank 10,
the waste water collecting pipeline 1 is used for collecting washing water and grey water which are 1 higher than the floor 16 where the water collecting tank 10 is located, and a water outlet of the waste water collecting pipeline 1 is connected with a water inlet of the precipitation filtering device;
the wash water refers to the waste water from the wash basin, and the grey water refers to the waste water from the mop washing basin 8. Certainly, bath water can be collected in a bathroom according to the water using requirement in the building.
The setting of the sedimentation and filtration device is higher than that of the water collection tank 10, the sedimentation and filtration device comprises a cylindrical main body 5, the top of the cylindrical main body 5 is provided with an inspection opening 4 for daily maintenance of the sedimentation and filtration device, the bottom of the cylindrical main body 5 is provided with a sewage discharge opening 7, the lower part of the cylindrical main body 5 is provided with a water inlet pipe 6, the upper part of the cylindrical main body 5 is provided with a water outlet pipe 2, the water outlet pipe 2 is internally provided with a filtration mechanism, and the water outlet pipe 2 is connected with a water inlet of the water collection tank 10.
By adopting the structure, the collected waste water enters the lower part of the water inlet pipe, the precipitate in the waste water is firstly precipitated to the position between the sewage outlet 7 and the water outlet under the action of gravity, the precipitate is firstly subjected to impurity removal, and then the waste water enters the water outlet pipe 2 to be filtered, and the filtered waste water is discharged. The structure is beneficial to the precipitation and filtration of impurities in the wastewater, the filtering pressure of the filtering mechanism can be effectively reduced, and the service life of the filtering mechanism is prolonged.
The water collecting tank 10 is arranged at the lower part of the wash basin 9, and the water outlet pipe 2 of the water collecting tank 10 is communicated with the water tanks of the toilets 18 which are 1 floor lower than the floor 16 where the water collecting tank 10 is located.
The filtering mechanism comprises a filter screen 3 arranged in the water outlet pipe 2.
The water collecting tank 10 is provided with an overflow pipe 11, the overflow pipe 11 is connected with a wastewater collecting pipeline 1 or a sewer pipe 17, the overflow pipe 11 mainly has the function of preventing the water collecting tank 10 from being overfilled, and overflowed water preferentially enters the wastewater collecting pipeline 1 to be collected and utilized again. The overflow water enters the down-comer pipe 17 not at the level 16 where the waste water is collected.
An automatic water replenishing device is arranged on the water collecting tank 10. The automatic water replenishing device is used for preventing collected waste water from being incapable of meeting daily utilization, and tap water is used for replenishing water in the water collecting tank 10 so as to prevent the flushing effect of the closestool 18 from being incapable of being completed. The automatic water replenishing device can be composed of a liquid level sensor, an electromagnetic valve and a single chip microcomputer. In this embodiment, the automatic water replenishing device is a float valve 12, and the water inlet end of the float valve 12 is connected with a tap water pipeline. The float valve 12 has a simple structure and low cost.
The operation process of the embodiment:
waste water such as washing water, grey water and the like enters the filtering mechanism through the waste water collecting pipeline 1 and the water inlet pipe 6 under the action of gravity, and the water after gravity precipitation and filtration is collected and stored in the water inlet collecting tank 10 under the action of gravity and is used for water for the closestool 18 on the lower floor 16. When the water in the water collecting tank 10 is over-full, the water flows out through the overflow pipe 11, and when the water in the water collecting tank 10 is too little, the tap water is automatically supplemented under the action of the ball float valve 12, so that the normal toilet flushing water is ensured. When the impurities in the filtering mechanism are excessive, the sewage outlet 7 is opened to discharge.
Example 2
As shown in fig. 2 and 4, basically the same as in embodiment 1, except that: in the embodiment, taking a six-storey building as an example, the water saving device comprises two building water saving devices, and the waste water collecting pipeline 1 is used for collecting washing water and grey water which are 2 times higher than the storey 16 where the water collecting tank 10 is located.
The filtering mechanism also comprises a filtering layer arranged behind the filtering net 3, and the filtering layer is active carbon 14 and/or sand 15. The active carbon 14 or the sand 15 is mainly arranged at the place with high requirements on recycling waste water with more impurities or more impurities, and is beneficial to improving the filtering effect. The implementation adopts two-layer filtration of active carbon and sandstone.
An additive pipe 13 is arranged on the water outlet pipe 2. The additive pipe 13 is mainly arranged for further optimizing treatment of the recycled wastewater, such as adding a deodorant, a bacteriostatic agent and the like.
The water consumption of the building in the embodiment is small, and the collected waste water on one floor is not enough to meet the water consumption of the next floor, so that the waste water on two floors is collected and used for flushing the toilet.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
