Active carbon filter core and preparation method thereof

Abstract

The invention relates to an active carbon filter core and a preparation method thereof. The active carbon filter core comprises is prepared from the following raw materials in parts by weight: 150 parts of polyethylene, 200 parts of active carbon, 100 parts of magnesium and 35 parts of a KDF filter material, wherein the iodine adsorption value of the active carbon is 1000-1200. The preparation method comprises the following steps: (1) mixing and uniformly stirring the polyethylene, the active carbon, the magnesium and the KDF filter material to obtain a mixed material; (2) putting the mixed material into a mould, then adding into a furnace for sintering heat treatment, cooling, and demoulding to obtain the active carbon filter core. The active carbon filter core has the beneficial effectsas follows: through a scientific ratio of the raw materials, the defects that the conventional active carbon filter core only uses an active carbon material and the adsorbing and purifying effects ofthe active carbon are poor are overcome; the active carbon has the particle size of 80-325 meshes, the adsorbing effect of the active carbon is fully played, and the purifying effect of the filter core is enhanced; a bonding moulding material in the filter core selects ultra-high molecular weight polyethylene, so that a water passage is not blocked, and the effect of the filter material is fully played; the filter core is firm, durable, good in gas diffusion, strong in filtration and strong in adsorption.

Description

technical field [0001] The invention relates to the field of liquid filtration and purification, in particular to an activated carbon filter element and a preparation method thereof. Background technique [0002] The filter medium refers to any porous material that allows the working medium to pass through and intercepts solid particles or liquid droplets in it to achieve the purpose of separation or purification. Commonly used filter media in industry are: ①woven material, filter cloth and filter screen woven from natural or synthetic fibers, metal wires, etc., are the most commonly used filter media in industrial production. Such materials are cheap, easy to clean and replace, and the minimum particle size that can be retained is 5-65 μm; ② Porous solids, including bisque, sintered metal or glass, or porous plastic tubes bonded by plastic fine powder Wait. The minimum particle size that can be intercepted by this type of material is 1-3μm, and it is often used to treat s...

Problems solved by technology

[0004] As far as the current water pollution environment is concerned, the selection and use of activated carbon is the core technical issue for water treatment and purification; the traditional activated carbon rod filter element has limited purification effect on organic chemical pollutants, and its activity is not strong for drinking water sourced from reservoirs.
