Description

A kind of built-up type reverse osmosis constant voltage water-purifying machine with heating

Technical field

The utility model relates to a kind of water-purifying machine with heating, and it is specifically related to a kind of built-up type reverse osmosis constant voltage water-purifying machine with heating.

Background technology

The subject matter that product exists is at present that soak test total number of bacterial colony exceeds standard.But existing reverse osmosis water purifier does not all kill the filter core of bacterium colony, the water that purifies out at whole reverse osmosis water purifier so again can produce total number of bacterial colony to pressure pot the inside and exceed standard, cause the injury to HUMAN HEALTH, existing reverse osmosis water purifier RO reverse osmosis membrane duration of service is short, there is no good control for the time of changing RO reverse osmosis membrane, cause or can not get timely replacing, or RO reverse osmosis membrane is not also just changed to work-ing life, causes waste.

Utility model content

Technical problem to be solved in the utility model is: improve the work-ing life of RO reverse osmosis membrane, improve cleaning water, accurately grasp the replacing time of RO reverse osmosis membrane, the problem of effectively avoiding pure water bacterium to exceed standard.For achieving the above object, the technical scheme that the utility model provides is, a kind of built-up type reverse osmosis constant voltage water-purifying machine with heating, comprise water pump and the filtering unit being connected with water inlet pipe successively and RO reverse osmosis membrane processing unit, the water butt being connected with the rising pipe of RO reverse osmosis membrane processing unit pure water, the water inlet pipe place of RO reverse osmosis membrane processing unit is provided with magnetic valve, the waste pipe place of RO reverse osmosis membrane processing unit is also connected with return water pipe, for the feed-water end to RO reverse osmosis membrane processing unit by return of waste water, described return water pipe and waste water outlet end are provided with variable valve, be used for regulating hydraulic pressure and flow velocity, the water outlet pipe end of pure water is also connected with heating tank.

Described filtering unit comprises PP filter core, activated carbon cartridge, accurate activated carbon cartridge.

Described water butt is made up of KDF+ gac+medical stone material.

Described RO reverse osmosis membrane processing unit is also provided with pressure-display device.

The water purifier of prior art, RO reverse osmosis membrane only has the work-ing life of 2-6 month conventionally, because the particle that is difficult to see through at the surface sediment of RO reverse osmosis membrane after life-time service, cause flow rate of water flow to slow down, surface is breed bacteria easily, and the output capacity of pure water is significantly reduced, and prior art pure water is 1:4 with the waste water ratio of draining conventionally, because RO reverse osmosis membrane packed particle breed bacteria can make this ratio significantly improve.And use the technical solution of the utility model, due to arrange at waste water outlet end return line by part return of waste water to feed-water end, impel the flow velocity of the RO reverse osmosis membrane of flowing through to accelerate, RO reverse osmosis membrane has been played to certain washing action, avoid surperficial macrobead to pile up and cause perviousness variation and breed bacteria, more than conventionally making the life to 18 month of RO reverse osmosis membrane.Because part return of waste water passes through RO reverse osmosis membrane again, improved the output capacity of pure water, through the control of variable valve, pure water and the waste water ratio of draining can be reached for 1:2 conventionally between 1:1 simultaneously.In addition, owing to having adopted return of waste water and return line and waste water outlet end all to adopt variable valve, hydraulic pressure can set more accurately product operation time, while making product operation, can adjust according to situations such as water quality, feed-water end hydraulic pressure, water pumps in good time, with best hydraulic pressure running, avoid causing because hydraulic pressure is excessive the situation of damage of product to occur.In addition, water butt adopts " gac+KDF+ or medical stone " filtrate, and (Kai get Fei KDF is highly purified copper/zinc alloy granules, it carries out water treatment work by micro-electrochemical redox reaction Redox, in the time contacting with water, two kinds of metals in alloy form countless little galvanic cell systems on submicroscopic yardstick, this material has powerful response capacity and the speed of response being exceedingly fast in water, can remove in water up to metal ion and compounds such as the lead dissolving in the chlorine of 99 % and water, mercury, nickel, chromium.To anti-bacteria, fungi, dirt, algae to grow effect distinguished.Can guarantee to be stored in water in water butt because of not breed bacteria of long period, prevent that pure water after purifying is because leaving the secondary pollution forming in water butt in.Prior art, for conventionally utilizing the time to calculate, is worked because of water quality, the impact of flow on its work-ing life and ignore RO reverse osmosis membrane self in work-ing life of RO reverse osmosis membrane, conventionally changes RO reverse osmosis membrane by the cycle of 2-6 month.RO reverse osmosis membrane and the equipment that plays a major role higher as relative price in water-purifying machine, such way has two problems conventionally, and one is that RO reverse osmosis membrane does not damage itself, and changes the use cost that has increased undoubtedly user by the time; Another one problem is that RO reverse osmosis membrane has damaged but also not to the replacement cycle, and now uses the water quality purifying beyond doubt to go wrong and energy consumption strengthens.The utility model is also provided with the way of pressure-display device after by the magnetic valve at water inlet pipe place, RO reverse osmosis membrane processing unit and water inlet pipe, whether normal by monitoring this place's hydraulic pressure, monitor that whether RO reverse osmosis membrane is working properly, judge whether in proper order to change RO reverse osmosis membrane.Because RO reverse osmosis membrane is as normal work, hydraulic pressure is conventionally stable, as cisco unity malfunction of RO reverse osmosis membrane, can cause due to the intransitable particle of surface sediment the water-permeable variation of RO reverse osmosis membrane, cause variation in water pressure, monitor that with this working order of RO reverse osmosis membrane determines whether to need to change, can grasp more in time, accurately the replacing time of RO reverse osmosis membrane.To select in order providing to user more, can to install heating tank additional at the rising pipe place of pure water, heat for the pure water that water outlet pipe end is flowed out.
