Description

A kind of central water-purifying machine with contrary flushing

Technical field

The utility model relates to water correction plant, particularly the manufacturing field of the water-purifying machine of the tap water that uses for urban households and enterprises and institutions.

Background technology

The health organization investigation is pointed out, human diseases 80% is relevant with water, the main sterilization method of tap water is the chlorination sterilization, though can remove a large amount of bacteriums, but also exist objectionable impurities, especially the heavy metal in the water, compositions such as chlorine molecule and nitrite, course of conveying and water tower storage etc. all can cause secondary pollution to a certain degree, although with water boil, also can't remove the objectionable impuritiess such as heavy metal in the water, the excessive absorption of these materials can cause great harm to human body, threatening human healthy, the part of town and country tap water exceeds standard, and do not reach People's Republic of China's " drinking water sanitary standard ", and the present situation of above-mentioned pollution has constituted the very big threat to the town and country personnel health.

Known on the market many water-purifying machine product design simple structures, there are certain defective and deficiency, especially to the quick replacing of purification medium and a technology barrier that has arranged into this series products against flushing, its product mainly is based on the purification again to city tap-water, the purpose that reaches Drinking Water designs, can not solve rural and urban population and directly adopt self-control tap water water source after purifying, to be better than People's Republic of China's " drinking water sanitary standard ", become the purpose of direct drinking water.

The utility model content

The purpose of this utility model provides a kind of central water-purifying machine with contrary flushing, is better than the problem of the People's Republic of China's " drinking water sanitary standard " to solve the town and country tap water that exceeds standard after purifying.This novel purpose is realized by following technical scheme: a kind of central water-purifying machine with contrary flushing, comprise the spun yarn strainer, the KDF55 filtering layer, fibrous filter layer, coconut husk gac filtration layer, it is characterized in that: the bottom of its multiway valve is provided with the spiral external sealing plug, the spiral internal sealing plug that is provided with suitable for reading of cylindrical shell, the airtight circle of silica gel, the bottom of encloses container is provided with annular sieve plate, the top fine sand strainer that is disposed with from bottom to top of annular sieve plate, the KDF55 filtering layer, first fibrous filter layer, coconut husk gac filtration layer, second fibrous filter layer, the left side of this encloses container bottom is provided with water-in, contrary flushing pollution discharge mouth, the right side of encloses container top multiway valve has water outlet, the left side is provided with contrary flushing water inlet; The water outlet of former water is communicated with the water-in of filtration unit.

In the above-mentioned design, this novel employing one-level bed filtration device is with the different needs at town-dweller-rural-family and enterprises and institutions' drinking water treatment.As tap water that town and country are exceeded standard, this is novel to carry out to it that fine sand strainer filters, KDF55 filters, first layer of fibers filters the back, carry out the coconut husk gac filtration and the second layer of fibers filtration treatment again.

Compare with prior art (on the basis that existing filter sieve filters and activated carbon filtration is handled); this novel pin has increased treatment steps such as contrary flushing discharging, the filtration of fine sand strainer, KDF55 filtration, the filtration of first layer of fibers, coconut husk gac filtration, the second layer of fibers filtration to tap water (the comprise self-control tap water) water source that exceeds standard, town and country.During this was novel, the fine sand strainer can effectively be removed silt, iron rust, impurity, suspended substance, various mechanical impurity in the water, makes the water quality clarification, remove incrustation scale, improves the temperature of water outlet, and filter effect is up to more than 99.7%; KDF55 can effectively remove the chlorine residue in the water, remove soluble heavy metal, the controlling microbial growth, stop the accumulation of hard scale, deironing, reduce fluorochemical, nitrate, vitriol, can purify well water, remove chlorine, bacterium and algae in the tap water, reduce the mineral substance fouling and suppress microbial reproduction; First layer of fibers can effectively be removed the bigger fixedly impurity of the grains of sand, gravel, chip, tube wall anvil cinder and iron rust, impurity, suspended substance, part microorganism equal-volume in tap water and the underground surface water water; The coconut husk granulated active carbon is the organism in the absorption water, chemical pesticide, chlorine residue, heterochromatic peculiar smell etc. effectively; Second layer of fibers can be tackled the tiny fixedly impurity of removing in the water of the grains of sand, chip, tube wall anvil cinder and iron rust, impurity, suspended substance, part microorganism equal-volume effectively once more, avoid the filtrate flight, keep mineral substance and trace element simultaneously, thereby make the water quality mouthfeel sweet more pure sweet the human body beneficial; Can effectively discharge the various objectionable impuritiess that are suspended in the filter cylinder water body, discharge absorption in the lip-deep objectionable impurities of each filtering layer, contrary flushing ER for emission rate is up to more than 97%.

This is novel to have following characteristics: 1, can effectively remove silt, iron rust, impurity, suspended substance, various mechanical impurity in the water, make the water quality clarification, remove incrustation scale, improve the temperature of water outlet, filter effect is up to more than 99.7%.2, can effectively remove chlorine residue in the water, remove soluble heavy metal, the controlling microbial growth, stop the accumulation of hard scale, deironing, reduce fluorochemical, nitrate, vitriol, can purify well water, remove chlorine, bacterium and algae in the tap water, reduce the mineral substance fouling and suppress microbial reproduction.3, can effectively remove the bigger fixedly impurity of the grains of sand, gravel, chip, tube wall anvil cinder and iron rust, impurity, suspended substance, part microorganism equal-volume in tap water and the underground surface water water.4, the effectively organism in the absorption water, chemical pesticide, chlorine residue, heterochromatic peculiar smell etc.5, can tackle the tiny fixedly impurity of removing in the water of the grains of sand, chip, tube wall anvil cinder and iron rust, impurity, suspended substance, part microorganism equal-volume effectively once more, avoid the filtrate flight, keep mineral substance and trace element simultaneously, thereby make the water quality mouthfeel sweet more pure sweet the human body beneficial.6, can effectively discharge the various objectionable impuritiess that are suspended in the filter cylinder water body, discharge absorption in the lip-deep objectionable impurities of each filtering layer, contrary flushing ER for emission rate is up to more than 97%.7, filter back water quality and be better than People's Republic of China's " drinking water sanitary standard " requirement.

This novel economizer is suitable for, and system water effect is remarkable, and be particularly suitable for town-dweller-rural-family and enterprises and institutions and use, but the each household configuration.
