Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The utility model discloses an antistatic filtration is with straining a section of thick bamboo strains a section of thick bamboo and includes cylindrical cavity barrel 1, and cavity barrel forms the reticular surface, and the both ends of cavity barrel 1 are connected with top lid 2 and bottom lid 3. The outer peripheral wall of the hollow cylinder body 1 is covered with the pleated filter material layer 4, and the pleated structure can increase the filtering area and achieve better filtering effect.

The filter material layer 4 of the present invention includes an antistatic layer 42 and a polytetrafluoroethylene film layer 43 attached to the outer surface of the substrate layer 41. The substrate layer 41 may be a polyester nonwoven fabric, a sateen, paper, or conventional cellulose. The anti-static layer 42 may be a conductive aluminum coating layer on the substrate layer, or an acrylic resin fiber layer to play a role in static resistance and explosion resistance. The substrate layer 41 may have oil-proof, water-proof, and stain-proof functions, depending on the actual situation. The teflon film sheet 43 may include a first teflon film and a second teflon film attached to each other and having a thickness of 0.1-0.5um, and the directions of the micropores of the first teflon film and the second teflon film are arranged to cross each other, and particularly, when manufacturing, the first teflon film and the second teflon film are alternately stacked so that the directions of the micropores of the first teflon film and the second teflon film are arranged to cross each other, and the crossing angle is preferably 45 °.

The utility model discloses in, the surface of cavity barrel 1 still is equipped with active carbon adsorption layer 5. The activated carbon adsorption layer 5 may be activated carbon adsorption cotton or a thin activated carbon filter cartridge, and may be adhered to the outer surface of the hollow cylinder 1. The activated carbon adsorption layer 5 has rich micropores and strong adsorption capacity, can be fully contacted with gas (impurities), and effectively adsorbs pollutants such as residual chlorine and micromolecular organic matters which cannot be removed in the preceding stage of filtration.
