Description

A secondary utilization device for domestic water

The utility model relates to a device for water intake, water collection and water distribution in daily life, in particular to a device capable of realizing secondary utilization of domestic water.

At present, the shortage of water resources is a common phenomenon in our country. Especially with the expansion of cities and the development of urban industries, groundwater is used unrestrainedly; in rural areas, the land is opened up too much, vegetation is destroyed, water and soil erosion is very serious, and waste and pollution in the use of water resources are very prominent. More than 80% of the cities in North China and Northeast China have experienced water shortages, and have to limit water supply, supply water for a limited time, and plan to use water. According to relevant statistics, the subsidence of more than a dozen urban centers in North China has reached as much as 1.6 meters, and more than 40,000 motor-driven wells in Hebei Province are scrapped every year. In terms of industrial water use, relevant parties have introduced a number of measures to control it. But in terms of domestic water use, there is still no effective way to achieve the purpose of water saving, and due to the improvement of the quality of life and the improvement of sanitation facilities, the water consumption has not only not declined, but has even continued to rise. Secondary utilization of domestic water has not been implemented. Taking Beijing as an example, the city and its districts have a population of nearly 11.8 million. If each household has 3.5 persons, there are 3.37 million households. Based on 20 cubic meters of domestic water per household per month, the monthly domestic water consumption is 67.42 million cubic meters, and the annual domestic water consumption reaches 809 million cubic meters. The current water conservation measures only focus on quantity and price, and there is no effective countermeasure for the secondary utilization of domestic water.

The purpose of this utility model is to provide a secondary utilization device for domestic water, which can not only greatly reduce the total amount of domestic water, but also reduce the discharge of domestic sewage and the discharge of organic matter in domestic sewage, which is beneficial to the environment pollution control.

The purpose of this utility model is achieved like this: establish a connecting pipe, this connecting pipe is communicated with the sewer pipe of washbasin, washing machine, bathtub, washbasin, can accept the domestic sewage of washbasin, washing machine, bathtub and washbasin, sent to the storage tank. The sink is transformed to make the upper part a sink, and the lower part to be a filter pool, and a filter screen is installed to filter sundries in the water. A water tank filter screen and an overflow pipe are arranged on the upper part of the water tank. When the water level in the storage tank is too high, it will automatically flow into the sewer through the overflow pipe. An outlet pipe is arranged at the bottom of the water storage tank to be connected with the water storage tank through a miniature electric water pump. The storage tank is located above the toilet tank. Close the power switch of the miniature electric water pump, and the water pump can pump the filtered water in the storage tank into the water storage tank. There is a water level display tube on the outside of the water storage tank, and a water filling self-stop switch moved by a floating ball inside. When the water level reaches the limited water level, the floating ball pushes the self-stop switch, cuts off the power supply of the water pump, and stops the water supply. There is a pipe at the bottom of the water storage tank to be connected with the toilet water tank, so that the water storage tank can directly supply water to the toilet water tank. In the above-mentioned whole system, the original water supply channel remains unchanged, but is deactivated by a switch.

After adopting the above-mentioned device, the domestic water of washbasins, washing machines, bathtubs and dishwashing basins directly discharged into the sewer originally can be used as flush toilet water after being filtered, and four outstanding effects can be achieved. First, because the flushing volume of flush toilets on the market is generally about 15 liters or more and there is an obvious smell if the urine is not flushed completely, the hygienic habit requires people to press the switch to flush regardless of urine or toilet. Take 15 times per day as an example for each household. , the daily flush toilet water is 225 liters. According to sampling estimates, the water for flush toilets accounts for more than 40% of the entire domestic water use. Through this device, the flush toilet can completely use the secondary water, and the total amount of domestic water can be saved by 40%. If this method is extended to the Beijing area, 25 million cubic meters of water can be saved per month, which has huge economic and social benefits, and has great impact on residents’ lives. There is no hindrance, only the bathtub needs to be raised, and water storage tanks and water storage tanks are built, and water channels are properly transformed, with less investment, and it is very convenient to design uniformly when building a new house. Second, because the utility model is provided with two filters in the sink and the water storage tank, if every household filters out 100 grams of solid organic matter every day, more than 3 million households in Beijing can filter out 337 tons of solid organic matter every day, that is, It saves 123,000 tons of solid organic matter from being discharged into sewers and rivers every year. And these organic matters are discharged into rivers, lakes and seas, 1 kilogram of organic matter makes 10 cubic meters of water eutrophication, and 12 billion cubic meters of clean water will become sewage throughout the year, so the implementation of the utility model can bring very prominent social benefits. Third, with reference to the above-mentioned methods, the water intake systems of schools, hotels, restaurants, and public toilets can be properly transformed, and the above-mentioned effects can also be achieved, which can be generalized. Fourth, the development of secondary utilization of domestic water not only reduces the exploitation of a large amount of groundwater, but also reduces the processing capacity of water plants, saves energy, and the saved water can be used for agricultural irrigation or water conservation, which is beneficial to future generations. Has incalculable long-term benefits.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

1. Wash basin 2. Washing machine 3. Bathtub 4. Sink 5. Sink filter 6. Water tank 7. Water tank filter 8. Overflow pipe 9. Floor drain 10. Micro electric water pump 11. Water tank 12. Water level display tube 13. Water filling automatic stop switch 14. Flush toilet water tank 15. Flush toilet.

In daily life, the water of washbasin 1, washing machine 2, bathtub 3, and sink 4 enters the accumulated water tank 6 through the drainpipe, and filter screen 5 is arranged on the lower side of the sink 4 to filter in advance. Water storage tank 6 tops also have filter screen 7 to carry out secondary filtration to incoming water. Start the miniature electric water pump 10, and the water in the storage tank is pumped into the water storage tank 11. According to the water level shown by the water level display tube 12 on the outside of the water storage tank 11, it can be decided when to start the miniature electric water pump 10. When the water level of the water storage tank 11 reaches the predetermined water level line, the floating ball touches the water filling self-stop switch 13, cuts off the power supply, and Water injection stops. Water storage tank 11 bottoms have pipeline to communicate with water closet water tank 14, as the water source of water closet 15.

What has been described above is only a common embodiment of the utility model. On the premise that the basic idea of the utility model remains unchanged, some modifications and improvements can also be made, which should also be regarded as the protection scope of the utility model.
