Technical Field

The utility model relates to an air filter technical field especially relates to a novel but high-efficient blowback air filter.

Background

The air filter element is a filter, also called air filter cartridge, air filter, style, etc. The air filter is mainly used for filtering air in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms. The air filter element pursues high efficiency low resistance, which means the reduction of running cost, and the air filter element among the prior art filtration efficiency is lower, and generally is disposable product, unable used repeatedly. In view of the above, it is necessary to design an air filter element to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to disclose a novel but high-efficient blowback air filter, the fine filter media of glass are folding to be arranged, and filter area is big, and filtration efficiency is high, and initial resistance is little, realizes high-efficient low resistance, and in addition, through the protection of stainless steel orifice plate and the support of metal mesh piece, play the effect of the fine filter media of protection glass, it is positive to increase the fine filter media of glass, reverse bearing capacity, ensures that the fine filter media of glass can bear blowback pressure, satisfies the performance of regenerating of the fine filter media of glass, prolongs the life of the fine filter media of glass.

In order to achieve the purpose, the utility model provides a novel high-efficiency back-blowing air filter element, which comprises an outer frame with two open ends, a glass fiber filter material which is arranged in the outer frame and is in folding arrangement, a stainless steel punching plate arranged at the open end of the outer frame, and a plurality of metal meshes connected on the stainless steel punching plate; the metal mesh extends into the folding gap of the glass fiber filter material.

In some embodiments, a silicone gasket is bonded to the open end of the outer frame.

In some embodiments, the glass fiber filter material is bonded in the outer frame.

In some embodiments, the fiberglass filter has a fold height of 280mm to 290 mm.

In some embodiments, the metal mesh has a thickness of 0.5mm to 1.5mm and the metal mesh has an open cell content of 50% to 70%.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a novel but high-efficient blowback air filter, the fine filter media of glass is folding arranging, and filter area is big, and filtration efficiency is high, and initial resistance is little, has realized high-efficient low resistance, in addition, through the protection of stainless steel towards the orifice plate and the support of metal mesh piece, has played the effect of the fine filter media of protection glass, has increased fine filter media of glass just, reverse bearing capacity, has ensured that fine filter media of glass can bear blowback pressure, has satisfied the reproducible performance of the fine filter media of glass, has prolonged the life of the fine filter media of glass.

Drawings

Fig. 1 is a schematic structural view of a novel efficient blowback air filter element shown in the present invention;

FIG. 2 is a top view of FIG. 1;

fig. 3 is a sectional view taken along line a-a of fig. 2 (with the outer frame omitted).

Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

As shown in fig. 1-3, a novel high-efficiency back-flushing air filter element comprises an outer frame 1 with two open ends, a glass fiber filter material 4 which is arranged in the outer frame 1 and is folded, a stainless steel punching plate 2 arranged at the open end of the outer frame 1, and a plurality of metal meshes 5 connected to the stainless steel punching plate 2.

The glass fiber filter material 4 is bonded and sealed in the outer frame 1 through epoxy glue. The folding height of the glass fiber filter material 4 is 285mm, the filtering area is large, the filtering efficiency reaches H14 level, the initial resistance is less than 250Pa, high efficiency and low resistance are realized, and the glass fiber filter material is suitable for large air volume air purification equipment and process equipment in various occasions.
