Description

FIELD OF THE INVENTION [0001] The present invention relates to an air filter,

The present invention relates to a filter assembly and a manufacturing method thereof.

Generally, an air filter for removing foreign matters in air is composed of a filter filter material and a filter frame surrounding the filter material. The air filter is divided into a pre-filter, a medium filter, and a hepa filter. Such an air filter is used for general building air conditioning, hospital building air conditioning, semiconductor manufacturing chamber air conditioning, and the like.

1 is a sectional view showing an example of a conventional cylindrical air filter. 2 is a cross-sectional view of an example of a conventional cylindrical air filter.

1, an example of a conventional cylindrical air filter includes a filter filter media assembly 100 formed in a cylindrical shape, an upper cover 200 for covering and supporting the upper surface of the filter filter media assembly 100, A lower cover 300 covering and supporting the lower surface of the assembly 100, an upper sealing adhesive A1 provided on the upper surface of the filter media assembly 100 and the lower surface of the upper cover 200, And a lower sealing adhesive A2 provided on the upper surface of the lower cover 300. [

The filter media material assembly 100 includes a filter material 110 having a tubular shape that is folded in a zigzag fashion and an inner cylindrical mesh 120 supporting an inner circumferential surface of the filter material 110, And an outer cylindrical mash 130 supporting an outer peripheral surface of the outer cylindrical mash 130.

The upper cover 200 is composed of an upper side plate 210 and a lower side plate 220 attached to the lower surfaces of the upper side plate 210. The upper side plate 210 has a base plate 211 formed in an annular shape, An outer edge portion 212 which is bent and extended upwardly on the outer peripheral surface of the plate portion 211 and an inner edge portion 213 which is bent and extended downward on the inner peripheral surface of the base plate portion 211. The lower plate 220 includes a base plate portion 221 formed in an annular shape and a rim portion 222 bent and bent downward on the outer peripheral surface of the base plate portion 221. The inner diameter of the base plate portion 221 of the lower side plate 220 is larger than the outer diameter of the inner side edge portion 213 of the upper side plate 210 and the inner diameter of the rim of the lower side plate 220 is larger than the outer diameter of the filter media assembly 100 Same or slightly larger. The upper side plate 210 and the lower side plate 220 are attached by spot welding and are arranged between the inner edge portion 213 of the upper side plate 210 and the edge portion 222 of the lower side plate 220, Is inserted into the insertion groove of the annular shape.

The lower cover 300 includes a base plate portion 311 formed in an annular shape, an inclined plate portion 312 bent and extended in an annular shape on the inner peripheral surface of the base plate portion 311, a circular plate portion 312 extending from the inner peripheral surface of the inclined plate portion 312, (313), and a rim portion (314) that is bent and extended on the outer peripheral surface of the base plate portion (311).

The assembly process of the conventional cylindrical air filter is as follows.

The upper cover 200 and the upper surface of the filter media assemblage assembly 100 are inserted between the lower panel edge 222 of the upper cover 200 and the upper edge of the upper panel inner side edge 213, And the sealing adhesive is cured. At this time, the sealing adhesive A1 is injected while the lower side plate 220 of the upper cover 200 is positioned on the upper side. The lower end of the filter media assembly 100 is placed on the lower cover 300 so that the lower end of the filter media assembly 100 contacts the upper surface of the base plate 311 of the lower cover 300. At this time, the outer peripheral surface of the lower end of the filter media assembly 100 and the inner peripheral surface of the rim of the lower cover 300 are inserted into contact with each other. Then, a sealing adhesive (A2) is injected between the lower cover (300) and the lower surface of the filter media assembly (100) to cure the sealing adhesive. The sealing adhesive A1 provided at the upper end of the filter media assembly 100 not only seals the filter media assembly 100 and the upper cover 200 but also joins the two parts, The sealing adhesive A2 not only seals between the filter media assembly 100 and the lower cover 300 but also joins the two parts.

However, in the conventional cylindrical air filter as described above, the sealing adhesive A1 is injected between the upper cover 200 and the upper end of the filter media assembly 100 to harden the lower cover 300, Since the sealing adhesive A2 is injected between the lower ends of the sealing members A1 and A2 to harden the sealing adhesives A1 and A2, it takes a long time to cure the sealing adhesives A1 and A2. As a result, the assembly productivity of the air filter deteriorates.

In addition, when the conventional cylindrical air filter is installed in the entire system and the pores of the filter media 110 are clogged after a certain period of use, the cylindrical air filter is replaced with another cylindrical air filter. At this time, the pores of the filter media 110 are clogged and the replaced cylindrical air filter is discarded. This not only increases the loss of material, but also increases the amount of waste.

Hereinafter, the functions and effects of the air filter and the manufacturing method thereof according to the present invention will be described.

The air filter according to the present invention is mounted on air ducts for general building air conditioning, hospital building air conditioning, semiconductor manufacturing chamber air conditioning, and the like. Air enters the inner cylindrical mesh 120 of the filter media assembly 100 and passes through the filter media 110 and out through the outer cylindrical mesh 130 so that foreign matter mixed in the air is filtered into the filter media 110 . Air is introduced through the outer cylindrical mash 130 of the filter media assembly 100 and through the filter media 110 and out through the inner cylindrical mash 120 to flow along the interior of the inner cylindrical mash 120 While foreign matters mixed in the air are filtered into the filter filter material 110.

The upper cover 400 and the lower cover 500 are separated from the filter media assembly 100 and the upper cover 400 and the lower cover 500 are separated from each other after separating the fastening unit 600, The sealing members S1 and S2, which are respectively coupled to the first and second sealing members S1 and S2, are separated. After the filter media assemblies 100 and the sealing members S1 and S2 are replaced with new ones, the sealing members S1 and S2 are coupled to the upper cover 400 and the lower cover 500, 400 and the lower cover 500 to the upper and lower ends of the new filter media assembly 100, respectively. The upper cover 400 and the lower cover 500 are fastened by the fastening unit 600. [ The filter filter media assembly 100 and the air filter in which the sealing member is replaced are installed at the installation position.

As described above, according to the present invention, since only the filter media media assembly 100 and the sealing members S1 and S2 are replaced and the upper cover 400, the lower cover 500 and the fastening unit 600 are used as they are, Thereby minimizing losses and reducing maintenance costs and reducing the amount of waste.

The sealing member S1 and S2 are coupled to the upper cover 400 and the lower cover 500 during assembly and the upper cover 400 and the lower cover 500 are disposed on upper and lower portions of the filter media assembly 100, The upper cover 400 and the lower cover 500 are fastened together with the fastening unit 600 after the upper cover 400 and the lower cover 500 are coupled to each other. Thus, the assembling work is simple and the assembling time is shortened. That is, as in the prior art, the operation of injecting the sealing adhesive into the upper and lower ends of the filter media assembly 100 and curing the sealing adhesive is eliminated, and the assembling work is simplified and the assembling time is shortened.
