Water saving device for automatically reclaiming domestic waste water

Abstract

The invention provides a water saving device to recycle domestic wastewater automatically. The device utilizes the surplus pressure generated when urban tap water pipe net supplies water to families to enhance potential energy of the domestic wastewater, recycles domestic wastewater and automatically supplies to toilet according to the hydraulic principle. The device comprises a water bag, a filter, a water storage tank, a connecting rod, a reversing valve, a check valve, a box shell, etc. The device is driven by surplus pressure of the tap water, recycles the domestic waste water to flush toilet, needs no other power to be added, saves domestic water using, can replace water treatment device of the community and has great importance on reasonable water using and relieving the serious status of water shortage in China.

Description

Technical field [0001] The invention relates to a water-saving device which automatically recovers household domestic waste water and automatically supplies it to a toilet. Background technique [0002] my country's per capita water resources are short, and there are many unreasonable and improvementable areas in the use of water resources. The domestic wastewater in urban households, such as bath water, washing water, and vegetable washing water, is often discharged directly. This part of the water has high usable value and a large amount of water, which can be recycled for flushing the toilet; while household toilets are mostly used For flushing with tap water, if each person in a family of 3 uses the toilet 3 times a day, and the consumption is 6 liters each time, then this family will consume 54 liters of tap water a day, and consume at least 19,710 liters of tap water a year. According to my country's current population situation, this is a huge and unreasonable consum...

Problems solved by technology

Under normal circumstances, the probability of fire in modern buildings is very small. When the building is safe, this part of the excess pressure is lost as friction and converted into kinetic energy, and it also increases the burden on the water supply pump.
