Device for flushing toilet by constant-pressure reuse water supplied through processing washing water and rainwater

Abstract

The invention discloses a device for flushing a toilet by constant-pressure reuse water supplied through processing washing water and rainwater. The device comprises a water storage tank, a connecting pipeline, a rainwater collecting pipeline, a faucet, a washing basin, a toilet seat flushing tank, a liquid level switch, a liquid level sensor, a water pump motor, an electromagnetic valve and a control box, wherein the water storage tank comprises a rainwater pond, a washing water mixed settling pond, a sterilization disinfecting pond and a clear water pond; mud in the reuse water is precipitated through thick and fine mesh deletion filter screens, and the reuse water is subjected to ozone sterilization disinfection; and the secondary clear water keeps circulating at the constant pressure to supply the reuse water through the functions of a frequency changer of a PLC (programmable logic controller), a PID (proportion integration differentiation) regulator, a pressure and liquid level sensor and each switch and the like, so that the problems that the storage amount of the reuse water is less, the secondary pollution is caused due to the fact that the reuse water is not processed, and the water cannot be used by users in the whole resident community because the water pressure of the whole pipeline is not enough are solved; the users in the whole building or the whole resident community can use the reuse water normally, and the water resources can be greatly saved.

Description

technical field [0001] The invention relates to a water saving device Background technique [0002] At present, in the field of secondary water utilization, most of the household water is used for flushing toilets. The Chinese utility model patent specification CN2639378Y discloses a building domestic water and roof rainwater recovery and utilization device. The utility model uses rainwater The collection box is arranged on the roof, while the recycling water tank and the toilet flushing water tank are respectively arranged in two adjacent upper and lower floors. Use the floor drop to flush the toilet with recycled secondary water to save energy. The recycled water on the first floor is used to water the flowers and trees in the campus or courtyard, so that the waste water can be fully utilized. Chinese Utility Model Patent Specification CN2639378Y discloses a pipeline system device for self-controlled secondary water flushing. The device includes at least one secondary wa...

AI Technical Summary

Problems solved by technology

This device has the ability to treat scrubbing water and rainwater to realize constant pressure water supply, which overcomes the small amount of reused water storage and occupies the building and use area. If the recycled water is not treated, it will cause secondary pollution, and the water pressure of the entire pipeline is insufficient, so it cannot be used in the entire residential area. use problem
