Embodiment Construction

[0017] See Figure 4 , Figure 5 The high-efficiency filter of the present invention includes a box body 10, and a filter element 20 is arranged in the box body 10. The filter element 20 includes a filter paper 21 and a partition 22, and the filter paper 21 is repeatedly folded to form a plurality of concave grooves 23 with opposite opening directions, see Figure 7 Each concave groove is provided with a partition 22, and the concave groove 23 formed by repeated folding of the filter paper 21 is a tapered groove, the cone top 231 of the cone groove is closed, and the cone bottom 232 is open. image 3 and Figure 8 Among them, IN is the air supply before filter paper filtration; OUT is the exhaust air after filter paper filtration.

[0018] See Figure 5 and Figure 6 , the partition 22 is a zigzag folding structure, and the zigzag section of the partition 22 is perpendicular to the tapered groove section of the filter paper 21; The plate corresponds to the number of zigza...

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 [0001] The invention relates to the field of air purification equipment, in particular to a high-efficiency filter. Background technique [0002] High-efficiency filters are mainly used to capture particles above 0.3um and various suspended solids in the air. They are widely used in the air-conditioning terminal delivery of dust-free purification workshops in industries such as optical electronics, LCD liquid crystals, biomedicine, precision instruments, and beverages and foods. Wind is an indispensable and important part in the field of air purification equipment. Existing high-efficiency filter comprises casing 10, is provided with filter element in casing 10, and filter element comprises filter paper 1 and dividing plate 2, see figure 1 , figure 2 The filter paper 1 is folded continuously and repeatedly to form several rectangular grooves of equal size, so that the folded filter paper forms rectangular grooves parallel to each other and the openings of ...
