In the water purification industry, there are four main application forms of membranes: flat membrane, tubular membrane, hollow fiber membrane and roll membrane. Among the four kinds of membranes, the flat membrane has the lowest price, especially the organic flat membrane, which has the lowest strength and is not easy to be made into membrane components, so it is greatly limited in practical application, mainly used in laboratories, laboratories, medical infusion sets, needle filters and so on. The patent uses a special structure to apply the flat membrane to the water purifier, creating a new application market for the flat membrane, which is also the low-end market with the largest demand in the water purifier industry. The successful design of refined membrane filter has won the national patent, and will quickly become the mainstream product in the low-end market of water purifier with its excellent performance and low price, and is expected to occupy more than one tenth of the whole water purifier market. A variety of modern technologies and methods are applied in the design, and the principle of value engineering is applied to optimize the function of the final scheme, so that it is simple and practical, close to the market, with the best function and the highest cost performance. If anyone wants to use the flat membrane for water purifier products again, it will be extremely passive not to adopt the structure designed in this patent and the combination form of flat membrane components and filter materials, that is to say, making the flat membrane water purifier is the privilege of this patent, and as long as other water purifiers use the flat membrane, it may be suspected of infringement.
At present, there is no real leading enterprise in China water purifier industry. Because of the huge profits and potential huge market of water purifiers, most water purifier manufacturers pay attention to the high-end market of water purifiers, and rarely care about the demand of ordinary people's families for water purifiers, which is the foundation of the water purifier market, occupying more than 60% of the market share. The existing water purifier enterprises only pursue high profits and ignore the needs of the general public, which is one of the main reasons for the slow development of the water purifier industry for many years. No matter what kind of products enter thousands of households and are generally accepted by people, they can drive the development and growth of the whole industry. The design of this patented product fully considers these needs, and strives to enter the water purifier market with the best performance and the lowest price, so that all families can afford and use water purification products. The customers of the water purifier products produced by this patented technology are mainly a large number of low-and middle-income families and floating population in cities and towns. While choosing product performance, they pay more attention to the price, applicability, use and maintenance cost of the product.
The water purification process of membrane filtration water purifier is: pre-protective film+fine filtration film+filter sheet +KDF+ ion exchange resin+coconut shell activated carbon+functional filter material+post-protective film+post-fine filtration film+filter sheet.
Functions of each membrane and filter material:
1. Pre-protective film can remove turbidity, rust and suspended particles;
2. Fine filtration membrane can effectively remove bacteria, organics and viruses;
3.KDF removes residual chlorine, heavy metal ions and compounds such as lead, mercury, nickel, cadmium and chromium dissolved in water, inhibits the growth of bacteria, fungi, dirt and algae, and effectively prolongs the service life of activated carbon, thus prolonging the service life of membrane modules;
4. Ion exchange resin can effectively reduce hardness and soften water quality;
5. Coconut shell activated carbon can effectively remove residual chlorine, organic matter, abnormal color, odor and heavy metals from tap water;
6. The functional filter material has the functions of improving the water quality of purified water and inhibiting bacteria, which makes the purified water weakly alkaline, has small molecular water, is easier to be absorbed, and is more beneficial to human health;
7. The filter can effectively absorb and remove turbidity, rust and suspended particles;
8. Post-filtration membrane can further effectively remove the residual harmful substances in tap water and make the water more pure.
The structural features of the membrane filtration water purifier are as follows:
1, three big pieces and three small pieces of pipe fittings are few, which reduces the production and manufacturing cost;
2, the overall size of the pipe fittings is matched, the production is relatively simple, the processing is easy, and the production efficiency is high;
3. Spiral structure, reliable sealing and convenient disassembly;
4. Both the filtering membrane and the filtering material are components, with stable product quality and convenient assembly and replacement;
5. The water purifier is large in size and adjustable in length to ensure the water purification effect;
6. It is easy to realize mass production and large-scale operation.
From the water purification process selection and structural characteristics of the above water purifier, we can know that the latest family-level multi-layer membrane filtration functional water purifier absorbs and summarizes the advantages of activated carbon filter element, water purifier and existing water purifier. After filtration and purification by multi-layer membranes and filter materials, the effluent quality is more guaranteed, the water purification effect is obvious, and there is no electricity or waste water. While effectively removing harmful substances in water, most beneficial substances and trace elements are retained, and the effluent is weakly alkaline and small molecular water, which is easy to remove. According to the pollution situation in different areas and the water quality of different water sources, the filter membrane and filter material are optimized and adjusted to ensure the effluent quality and the requirements of different users.
The installation of the water purifier is not limited by the site, and can be installed in the form of horizontal installation, vertical installation, wall hanging and desktop according to local conditions. The control valve is arranged at the front end of the water purifier to effectively prevent water leakage caused by installing the water purifier; According to the water output of the water purifier, it is easy to judge the clogging and replacement time of the membrane. The replacement period of pre-protective film and pre-fine filtering film is short, which effectively prevents dirt pollution and bacterial growth. The rear protective film, the rear fine filtering film and the filtering material have long service life. The filter membrane and the filter material are all made into components, and no professionals need to replace the membrane. Users can disassemble and replace it by themselves. Users can know how to install and replace at a glance, which greatly reduces the cost of replacement and maintenance. Moreover, the replacement of membrane components and the use cost are low, and dealers only need to prepare enough water purifier components, so the service cost is low.
After the project is completed and put into production, the products will enter the water purifier market with excellent water purification performance and low price. Consumers can install and replace membrane modules only by purchasing products and accessories, which is convenient for customers and reduces the phenomenon of high service cost caused by too complicated installation and replacement.
