Description

Hollow fiber membrane filter

The present invention relates to a device for filtering tap water, and more particularly to a hollow fiber membrane filter.

With over-exploitation and environmental pollution, the most indispensable water resources are relatively polluted. For example, factories discharge waste water containing asbestos, dioxin and heavy metals. Agricultural workers abuse pesticides and leave a lot of toxins. Acid rain brings The floating matter and toxins pollute the water source, the sewer pipeline is not renewed, the septic tank and the reservoir equipment are not properly connected, or the tap water quality is inferior, and a large amount of chlorine purification is required to cause pollution, and the building and the apartment are directly pumped through the motor. In a short period of time, a large amount of water in the water distribution pipe is extracted. When the peak water or water pressure is low, the pressure in the water pipe is less than the surrounding pressure. If there is crack in the pipeline, the siphon effect will be generated, and the outer sewage will be sucked into the tap water. In the tube, causing serious pollution, resulting in a cup of clear and clear water, may contain more than one thousand kinds of impurities, posing a serious threat to human health, which can be roughly divided into suspended solids, microorganisms, inorganic substances, organic matter And six categories such as gas.

Therefore, it must be filtered and used more comfortably. Most of the existing filter modules are made of polypropylene or granular activated carbon. Although polypropylene can intercept coarse impurities such as floats, microorganisms and sediment in water, The filter pore size is large, and it is not easy to filter particulate impurities. Although the granular activated carbon has strong adsorption force, it can adsorb organic substances in water such as odor molecules, pesticides or carcinogens such as trihalomethanes, and achieve the function of purifying water, and cause chlorine in water. The odorous substance also reacts with the carbon surface to achieve the odor, but the granular activated carbon has a poor effect on the removal of particulate impurities, and the granular activated carbon filter acts on anionic pollutants such as nitrate in water. There is no significant removal effect, and the removal of rust is quite limited. In addition, the bacteria will adhere to the surface of the granular activated carbon and grow into a biofilm, which will cause an increase in the number of bacteria in the filter module of the granular activated carbon. situation.

As described above, the conventional polypropylene material and granular activated carbon filter module cannot remove small molecular substances in water, and the surface of the granular activated carbon also adheres to bacteria to cause twinning, resulting in an increase in the bacteria content of the water. Therefore, if it is directly consumed after filtration, symptoms of physical discomfort may occur; thus, it is known that the existing polypropylene material and granular activated carbon filter module have room for improvement and improvement in drinking safety and practicality.

In order to solve the existing polypropylene material and the granular activated carbon filter module can not remove the small molecular substances in the water, and the granular activated carbon also has the problem of bacterial adhesion. The present invention provides a hollow fiber membrane filter, wherein each membrane filament is hollow and slender tubular, and the contaminants of the E. coli, Salmonella, various fungi and rust cannot pass through the pores on the surface of the membrane filament, and the contaminants are trapped outside the membrane. It not only avoids the adhesion of bacteria, but also preserves calcium, magnesium and potassium ions beneficial to the human body. It can be directly consumed after filtration, which can improve the safety and practicability of drinking.

The hollow fiber membrane filter core, wherein the plurality of membrane filaments are made of polyfluorene material.

The hollow fiber membrane filter cartridge has a cylindrical shape, and the water inlet hole and the water outlet hole are respectively disposed at two ends of the housing.

The hollow fiber membrane filter element, wherein the hollow fiber membrane filter element comprises an abutting portion which is a hollow cylinder and is located between the filter module and the water outlet hole.

The hollow fiber membrane filter core, wherein the water inlet hole is provided with a thread, and the water outlet hole is provided with a thread.

The hollow fiber membrane filter cartridge, wherein the housing comprises two protrusions and an outer surface, and the protrusions are annularly disposed on an outer surface of the housing, and the protrusions are respectively adjacent to the housing Both ends.

The hollow fiber membrane cartridge, wherein the casing is made of food grade ABS resin.

The enhancements achieved by the technical means of this creation are:  1. The hollow fiber membrane filter of the present invention has a hollow and slender tubular shape, and the pores on the surface of the membrane wire prevent the passage of substances such as Escherichia coli, Salmonella and rust, and trap the pollutants outside the membrane. It can avoid the adhesion of bacteria, and can also retain calcium, magnesium and potassium ions that are beneficial to the human body.  2. The hollow fiber membrane filter of the present invention has a sleeve sleeved on the membrane wire, can guide the tap water to flow through the membrane wire, and has a sealing ring sleeved on the sleeve to prevent unfiltered tap water from flowing between the sleeve and the casing. The gap is left to the filtered drinking water to increase the safety of drinking.
