Reverse osmosis water purification machine

Abstract

The reverse osmosis water purifying machine includes water inlet, the first non-return valve, water inlet solenoid valve, primary filter, booster pump, pre-filter combination and reverse osmosis membrane filter connected via pipeline, as well as waste water tank, pressure water tank, normal temperature water tap, etc connected via pipeline with valves.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a reverse osmosis pure water machine. Background technique [0002] With the improvement of living standards and the seriousness of water pollution, people's requirements for drinking water safety and hygiene are increasing day by day. Various types of water purification / pure water machines appear on the market to meet consumers' safety and hygiene needs, especially reverse osmosis. Pure water machines are increasingly favored by consumers. The traditional reverse osmosis water dispenser mainly has the following problems in the process of its use: 1. After the source water is treated by the reverse osmosis membrane filter device, it will produce pure water and concentrated water with a ratio of 1:3. Concentrated water, which accounts for up to three quarters, is directly discharged as waste water, resulting in serious waste of source water; 2. Purified pure water is stor...

AI Technical Summary

Problems solved by technology

The traditional reverse osmosis water dispenser mainly has the following problems in the process of its use: 1. After the source water is treated by the reverse osmosis membrane filter device, it will produce pure water and concentrated water with a ratio of 1:3. Concentrated water, which accounts for up to three quarters, is directly discharged as waste water, resulting in serious waste of source water; 2. Purified pure water is stored in pressure storage tanks. If no water is taken for a long time, it will be The pure water in the pressure storage tank may also breed bacteria, thus affecting the safety and sanitation of pure water; 3. After the pure water machine is used for a period of time, the reverse osmosis membrane is prone to chemical scale, organic and colloid pollution, microbial pollution and other pollution, such as If it is not cleaned for a long time or not cleaned in time, it will damage the reverse osmosis membrane, thus affecting the service life of the reverse osmosis membrane filter device

The reverse osmosis pure water machine does not circulate and purify the concentrated water, but discharges it for other uses, but the time and quantity of concentrated water produced are difficult to match with the time and quantity required for other aspects of water use. In some cases, the concentrated water is directly discharged as waste water, so it does not solve the problem of waste of source water

Another example is the utility model patent No. ZL01251236.2 issued by the State Intellectual Property Office on October 9, 2002. The disclosed reverse osmosis pure water machine regularly reverses the reverse osmosis membrane to prolong the reverse osmosis membrane. The role of the service life of the filter device, but the water purifier does not solve the problem of waste of source water
