Embodiment Construction

[0019] Such as Figure 1-2 As shown, the manufacturing method of the filter described in the embodiment of the present invention mainly includes the following steps:

[0020] (1) Prepare raw materials: First, put 100-325 mesh powdered activated carbon into the raw material pool, then put 100-250 mesh powdered activated zeolite into the raw material pool, and put an appropriate amount of adhesive into the raw material pool, according to the weight ratio of 1:10 Inject water into the raw material pool, then put synthetic fibers (1.5d×3mm and 2d×2mm) into the raw material pool, the automatic mixer stirs the raw material pool for 20 minutes, and wrap two layers of non-woven fabric on the porous plastic tube;

[0021] (2) Suction forming method: pump the raw materials in the raw material pool into the tank, install the porous plastic tube in the center of the injector, then dip the injector into the tank, open the injector, and the raw materials in the tank gather in the porous Th...

Abstract

The invention relates to a preparation method of an activated carbon filter. The preparation method includes the steps: (1) preparing raw materials: putting powdered activated carbon and powdered activated zeolite into a raw material pool, putting an adhesive into the raw material pool, injecting water according to a weight ratio, then putting a synthetic fiber into the raw material pool, stirring, and wrapping a porous plastic pipe with a two-layer non-woven fabric; (2) adopting a suction molding method: allowing the raw materials in a tank to gather on the porous plastic pipe, and eventually filling fully a whole suction and injection device; and (3) adopting an injection molding method: making the raw materials gather in an injection metal mold with the porous plastic pipe as the axle center, and eventually filling fully the whole injection metal mold. The beneficial effects are that the activated carbon filter can effectively remove peculiar smell and free organic compounds in water, and also can remove trace heavy metals such as cadmium, lead, chromium and the like in a liquid; no activated carbon and other adsorption media fall off, and thus secondary pollution is effectively avoided; through a precise mesh-number matching of activated carbon, the removal rate of cryptosporidium is high; and the liquid flow rate is increased, and the resistance is decreased.

Description

technical field [0001] The present invention relates to the index improvement and production technology of carbon filters, especially to a kind of activated carbon with double-effect function made of activated carbon, activated zeolite, adhesive, synthetic fiber, end cap, anti-leakage bushing, protective net and other raw materials How to make a filter. Background technique [0002] The traditional activated carbon filter is a kind of tank filter device, and its shell is filled with activated carbon, which is used to filter free matter, microorganisms, and some heavy metal ions in water, and can effectively reduce the chroma of water. Its function is mainly to remove Macromolecular organic matter, iron oxides, residual chlorine. The adsorption principle of activated carbon is: a layer of balanced surface concentration is formed on the surface of its particles, and then organic matter impurities are adsorbed into the activated carbon particles, and the adsorption effect at t...
