Equipment for backwashing water purifier by purified water and comprehensively using produced sewage

Abstract

The invention is named as equipment for backwashing a water purifier by purified water and comprehensively using produced sewage, aims to solve the problem that a section of purified water is polluted because of poor backwashing effect caused by a reason that an inner cavity of the water purifier is backwashed by running water in the reversible backwashing process and also fulfills the aim of obtaining washing water by mixing concentrated water produced by backwashing sewage and the water purifier and the running water. The equipment consists of the water purifier, a unidirectional electromagnetic valve, a middle storage pot, a sewage storage pot, a water flow type negative pressure pump, a purified water storage pot and an electromagnetic flow sensor. The concentrated water and the backwashing sewage produced by the water purifier are stored in the middle storage pot; when the washing water is in need, a water faucet is switched on; the running water generates negative pressure at a side opening of the pump through the water flow type negative pressure pump and also generates the negative pressure on the sewage storage pot; under the action of the negative pressure, the sewage in the sewage storage pot and the middle storage pot is absorbed into a mixing cavity of the negative pressure pump and then is mixed with the running water to be used as the washing water which is discharged; the aim of comprehensively using the sewage is fulfilled.

Description

Technical field [0001] The patent of the present invention relates to the concentrated water produced when the water purifier produces purified water and the backwash water used when the water purifier is backwashed. With clean water recoil, the recoil sewage generated and the concentrated water produced by the water purifier during the production of purified water are reasonably used as washing water. Background technique [0002] At present, the backflushing of water purifiers using membrane technology adopts reverse backflushing of tap water, that is, the inner cavity of the membrane of the water purifier is polluted, and the sewage generated and the water purifier produce a large amount of concentrated water when producing purified water. Purified water is unsafe and wastes water resources. Contents of the invention [0003] In order not to discharge the concentrated water produced in vain from the pollution of the inner chamber after recoil and the sewage and water p...

Problems solved by technology

[0002] At present, the backflushing of water purifiers using membrane technology adopts reverse backflushing of tap water, that is, the inner cavity of the membrane of the water purifier is polluted, and the generated sewage and a large amount of concentrated water produced by the water purifier are directly discharged when producing purified water. Clean water pollution is unsafe and a waste of water resources
