Abstract
The invention provides a high efficiency filter, which can solve the problems that air velocity is less, the dust holding capacity is small, the service life of filter paper is short, and the use cost is high in the existing high efficiency filter. The high efficiency filter comprises a box, wherein a filter element is arranged in the box, the filter element comprises filter paper and clapboards, the filter paper is repeatedly folded to be shaped, the filter is repeatedly folded and a plurality of concave grooves of which the directions of openings are opposite are formed, one clapboard is arranged in each concave groove, and the high efficiency filter is characterized in that the concave grooves forming by repeatedly folding to shape the filter paper are tapered grooves, and a conical roof of each tapered groove is closed, and a conical bottom of each tapered groove is open.
Description
Technical field
The present invention relates to air cleaning facility field, be specially high efficiency particulate air filter.
Background technology
High efficiency particulate air filter is mainly used in the particle of more than 0.3um in traps air and various suspension, it is widely used in optical electron, the manufacture of LCD liquid crystal, the air conditioning terminal air-supply in the industry dust-free purification workshops such as biological medicine, precision instrument, beverage/food is the indispensable important component part in air cleaning facility field.Existing high efficiency particulate air filter comprises casing 10, filter core is provided with in casing 10, filter core comprises filter paper 1 and dividing plate 2, see Fig. 1, Fig. 2, the some equal-sized rectangular recess of the continuous folding formation of filter paper 1, thus rectangular channel rugosity filter paper being formed be parallel to each other and adjacent rectangular channel opening is contrary, in each rectangular channel, dividing plate is set; Its in use, unfiltered wind is flowed out by the rectangular channel of lower ending opening after the rectangular channel of the upper end open of rugosity filter paper enters through Filter paper filtering, thus realizes filtration to air; Because its air intake direction is parallel with the rectangular groove wall of folded filter paper, see Fig. 3, thus it exists that the filter paper resistance that is subject to when air-flow flows in rugosity filter paper is large thus air output after causing filtration is little and dust containing capacity is little by inertia effects to cause air intake, and the service life of filter paper, use cost that is short, filter was high.
Summary of the invention
For the problems referred to above, the invention provides high efficiency particulate air filter, it can solve the problem that air output is little, dust containing capacity is little, filter paper service life is short, use cost is high that existing high efficiency particulate air filter exists.
High efficiency particulate air filter, it comprises casing, filter core is provided with in described casing, described filter core comprises filter paper and dividing plate, the folding shaping of described filter paper, the Baltimore groove that the some opening directions of the folding formation of described filter paper are contrary, is equipped with one piece of described dividing plate in every one Baltimore groove, it is characterized in that: the described Baltimore groove that the folding shaping of described filter paper is formed afterwards is cone tank, the vertex of a cone of described cone tank is closed, is bored bottom opening.
Further, described dividing plate is zigzag foldable structure, the serrated profile of described dividing plate and the cone tank cross section perpendicular of described filter paper.
Further, the corresponding described folded filter paper of described dividing plate be shaped after the zigzag flanging number of vertex of a cone end of cone tank be less than the corresponding described folded filter paper of described dividing plate be shaped after the zigzag flanging number of cone bottom of cone tank.
More one is progressive, and the zigzag flanging number of the cone bottom of the cone tank after the corresponding described folded filter paper of described dividing plate is shaped is three times of the zigzag flanging number of the vertex of a cone end of the cone tank after the corresponding described folded filter paper of described dividing plate is shaped.
Beneficial effect of the present invention is: the Baltimore groove of the folding formation of its filter paper is cone tank, thus effectively can increase and filter out air quantity, and its dust containing capacity is large, long service life; Dividing plate is zigzag foldable structure, and the taper dentation cross section perpendicular of the serrated profile of dividing plate and described filter paper, evenly can lead to air-flow, ensure air-out effect further.

Detailed description of the invention
See Fig. 4, Fig. 5, high efficiency particulate air filter of the present invention comprises casing 10, filter core 20 is provided with in described casing 10, filter core 20 comprises filter paper 21 and dividing plate 22, the Baltimore groove 23 that the some opening directions of the folding formation of filter paper 21 are contrary, is shown in Fig. 7, is equipped with one piece of described dividing plate 22 in every one Baltimore groove, the Baltimore groove 23 of the folding formation of filter paper 21 is cone tank, and the vertex of a cone 231 of cone tank is closed, the cone end 232 opening.In Fig. 3 and Fig. 8, IN is the air-supply signal before Filter paper filtering; OUT is the air draft signal after Filter paper filtering.
See Fig. 5 and Fig. 6, dividing plate 22 is zigzag foldable structure, the serrated profile of dividing plate 22 and the cone tank cross section perpendicular of filter paper 21; The zigzag flanging number of vertex of a cone end of the cone tank after the corresponding folded filter paper of dividing plate 22 is shaped be less than the corresponding described folded filter paper of dividing plate be shaped after the zigzag flanging number of cone bottom of cone tank, thus dividing plate 22 can be matched with the cone tank of filter paper 21 at the hem width of the zigzag flanging at folding rear two ends; In the present embodiment, the zigzag flanging number of the cone bottom of the cone tank after the shaping of dividing plate corresponding folded filter paper is three times of the zigzag flanging number of the vertex of a cone end of the cone tank after the corresponding described folded filter paper of described dividing plate is shaped.
In Fig. 1 and Fig. 4,11 is fluid sealant; In Fig. 2, Fig. 5 and Fig. 6,12 is sealing strip; In Fig. 4,30 is the angle stator that each side sheet room of casing 10 is connected and fixed.
