Filter core for filtering water solution and preparation method of filter core

Abstract

The invention relates to a microporous filter core for filtering water solution, in particular to a filter core for filtering water solution with filtering, adsorption and sterilization functions and a preparation method of the filter core. The filter core comprises 28 percent to 65 percent of diatomite, 13 percent to 50 percent of active carbon, 11 percent to 48 percent of polyethylene and 11 percent to 48 percent of medical stone according to the weight percentage. The filter core has the advantages that the material selection is reasonable, the produced filter core can be used for effectively removing impurities including rust, suspension materials, colloid and the like in tap water, residual chlorine in the tap water can be effectively removed, pathogenic bacteria can be effectively removed, and the retention rate reaches 99.99 percent. Meanwhile, the water passing flow rate can be increased, the service life is prolonged, and the filter core can be repeatedly used after being irregularly cleaned according to different water qualities. The preparation method of the filter core is simple, preparation materials only need to be mixed according to the certain weight ratio and uniformly mixed, and the finished product filter core can be produced after the materials are filled into a forming machine, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a microporous filter element for filtering aqueous solution, in particular to a filter element for filtering aqueous solution with functions of filtering, adsorption and sterilization and a preparation method thereof. Background technique [0002] There is currently an invention patent, the patent number is 200810006710X, and the publication date is November 12, 2008. This patent describes a carbon crystal microporous ceramic filter element, wherein the main components are diatomaceous earth, carbon powder, and silver ions. One fatal point of this patent is that it needs to isolate oxygen and sinter at a high temperature above 1000 degrees Celsius. The reason is: diatomaceous earth is the shell of algae in the ocean, and its main component is silicon dioxide (SIO2). The filter materials are bonded together to form a filter element to achieve the filtering effect. However, activated carbon burns violently with oxygen at a hig...
