Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the examples, the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0016] like figure 1 , The pleated filter core of this embodiment can be made of paper, chemical fiber, metal and other materials.

[0017] The outer cylinder 1 includes a plurality of outer pleats 11 distributed in the circumferential direction and extending longitudinally. The outer pleats 11 are evenly distributed around the circumference of the outer cylinder 1. The outer pleats 11 are bow-shaped pleats. The outer pleats 11 include large pleats 12 and small pleats 13 arranged at intervals , the large folds 12 have equal arc lengths, and the small folds 13 have equal arc lengths, the large folds 12 and the adjacent small folds 13 partially overlap each other, and the arc length ratio of the overlap is 8:5. Another branch pleat 14 is arra...

Abstract

The invention provides a pleated filtering core. The pleated filtering core is of a circular cylindrical shape, and is characterized by comprising an outer cylinder; the outer cylinder comprises a plurality of circumferentially distributed outer pleats extending longitudinally; the outer pleats are uniformly distributed around the circumference of the outer cylinder; the outer pleats are arch-shaped pleats; the outer pleats comprise large pleats and small pleats which are spaced apart; each of the large pleats has an equal arc length; each of the small pleats has an equal arc length; and the large pleats and the small pleats adjacent thereto are partially overlapped with each other. By adopting the pleated filtering core, the filtering area is greatly increased, the free space of the filtering core is reduced, the filtering effect is enhanced, and at the same time, the pleats are further stabilized, so that little possibility of displacement is ensured, the pleats of the filtering corecan be fully utilized, the material is saved and the cost is reduced.

Description

technical field [0001] The present invention relates to filter cores, in particular to pleated filter cores. Background technique [0002] Due to the limited effective filtration area of ​​the traditional bag filter system and the large retention volume of the filter bag, the market is gradually considering the use of cylindrical pleated filter cartridges or spiral pleated filter elements, but the outer periphery of the filter element There is still a lot of free space between adjacent folds. In particular, helically pleated filter elements include a plurality of longitudinal pleats arranged in a cylindrical configuration with the ends of the pleats rolled up to minimize the spacing between adjacent pleat faces near the outer diameter of the filter element, thereby Larger filter surface area than traditional radial pleat construction. However, there is still a lot of free space on the periphery of the spiral pleated filter in the past, which makes the ends of the pleats mo...
