Material and apparatus for filtering tap water, and method for mfg. said apparatus

Abstract

A filtering material for removing the harmful substance from running water is proportionally prepared from activated carbon, KDFT, calcium sulfite, zeolite molecular sieve, and Ag carried phosphate. Its filter apparatus is a multi-layer hollow structure composed of internal non-woven fabric layer, activated carbon mixed core layer, external non-woven fabric layer and plastic mesh layer. Its manufacture method features that its both ends are blocked by polyethene covers and its core layer is prepared from multiple substances through mixing and screw extruding out to become a hollow cylinder.

Description

technical field [0001] The invention relates to a tap water purification device, materials used and a manufacturing method of the purification device, in particular to a filter device capable of effectively removing harmful substances in tap water, materials used and a manufacturing method of the filter device. Background technique [0002] Tap water contains harmful substances such as bacteria, heavy metals, odorous gases, and pigments. According to statistics, tap water usually contains more than 2,000 compounds, of which more than 200 are harmful to humans. In the prior art, the main method for removing harmful substances in tap water is to use common activated carbon filter materials to filter the tap water. When the tap water flow rate is large, the adsorption capacity of the activated carbon filter material is very limited, and cannot effectively remove residual chlorine in tap water, and cannot effectively remove heavy metals in tap water; when the adsorption capacity...

AI Technical Summary

Problems solved by technology

When the tap water flow rate is large, the adsorption capacity of the activated carbon filter material is very limited, and cannot effectively remove residual chlorine in tap water, and cannot effectively remove heavy metals in tap water; when the adsorption capacity of the activated carbon filter material reaches saturation, the activated carbon filter element must be replaced , otherwise it will not be able to play a filtering role, and frequent replacement of activated carbon filter elements will bring inconvenience to users and increase the cost of use

At the same time, ordinary activated carbon filter materials cannot inhibit the growth of bacteria. In order to achieve the purpose of antibacterial, the patent number is 93241418.4, the publication number is 2167981, and the utility model patent named "new filter rod for water purification" discloses a water purification The filter rod includes a shell an
