[0017] Example 1

[0018] A preparation method of an activated carbon fiber filter core, the method comprises the following steps:

[0019] 1) Pulverize the activated carbon fiber loaded with bactericide (containing salts such as silver, copper, zinc, etc.), then mix with polypropylene binder, beating in the beating pool 1, water, activated carbon fiber, hot melt adhesive The weight ratio of the binder is 1000:15:0.5.

[0020] 2) The material after beating is put into the suction pool 2 for stirring by the stirring pump 3, and the stirring is uniform.

[0021] 3) Put the suction device of the installed inner mold into the suction pool 2 and suck for 1-50 minutes, and the activated carbon fiber filter core is formed in the inner mold of the suction device to form an adsorption layer 12, and the inner mold is raised; the During the suction process, the water enters the filter cloth 5 covered by the skeleton 4 and enters the buffer tank 8 through the suction pipe 6, and the buf...

Abstract

The invention relates to a method for preparing an activated carbon fiber filter core, and the method comprises the following steps: activated carbon fiber which carries with an bactericide is mixed with activated carbon after being crushed or ground, and then is blended with a hot melting binder, and beating is carried out in water; the beated material is put in a suction pool for being stirred, and the stirring is even; suction mold is carried out in the internal mold of an aspirator; the moulded activated carbon fiber filter core is put into an oven for drying, and the finished product is obtained after melting; the activated carbon fiber filter core prepared by the invention through the moulding mode of the internal mold arranged on the aspirator has the advantages that the fiber bonding is tight, the content of the binder is lower, and the specific surface area of the activated carbon fiber is not influenced; the bactericide is loaded on the activated carbon fiber, thereby not only restraining the growth of bacteria and algae on the filter core, but also killing the bacteria and the algae in water, and sterilization ions such as silver, copper, etc. cannot cause shedding easily, thereby greatly improving the purity and the germicidal efficacy of the activated carbon fiber.

Description

technical field [0001] The invention relates to a product and a preparation method for drinking water and other clean water purification, medicine, brewing, food decolorization, organic solvent adsorption and filtration, in particular to a preparation method of an activated carbon fiber filter core. Background technique [0002] Activated carbon fiber has a very large specific surface area and strong adsorption, decolorization, and odor removal properties, and can be widely used in water treatment and air filtration and purification, especially in drinking water purification. [0003] At present, domestic activated carbon or activated carbon fiber filter elements mainly adopt the molding process of molding or winding. The disadvantage of molding is that the content of filter element binder is too large, which will significantly reduce the specific surface area of ​​activated carbon or activated carbon fiber, making it adsorb, decolorize, The deodorizing performance is greatl...
