Description

Technical Field

[0001] The utility model belongs to the field of internal combustion engine accessories, and particularly relates to a filter element adopting a folded filter paper arrangement structure. Background Art

[0002] A filter is an accessory for internal combustion engines. Its function is to filter dust particles from the air and allow clean air to enter the engine cylinders, ensuring engine performance and normal operation. A filter typically consists of a filter cartridge, a filter element, and an intake pipe. The filter element divides the filter cartridge into a pre-filtration area and a post-filtration area. During operation, gas enters the pre-filtration area of ​​the filter cartridge through the intake pipe, is filtered by the filter element, and then enters the post-filtration area. Filtered sand is discharged from the sand outlet of the filter cartridge, and the filtered gas is discharged through the air outlet.

[0003] Traditional filter elements are usually cylindrical bodies made of a single filter paper. The filter paper is arranged in a circular shape, and the contact area with the air is small, which is not conducive to increasing the air intake. The filtration accuracy and filtration efficiency are low. After working for a period of time, the pressure difference between the front and rear increases, which hinders the air intake, and cleaning is inconvenient and incomplete. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a filter element adopting a folded filter paper arrangement structure to improve the filtering effect.

[0005] The filter element adopting a folded filter paper arrangement structure includes a filter element assembly, which includes a filter element frame and a filter paper component installed in the filter element frame. The filter paper component includes a plurality of continuously folded filter element pleated units, and the filter element pleated unit includes two filter element paper edges, and the outer ends of the two filter element paper edges are bent transitions.

[0006] Furthermore, the total length of the filter paper assembly when unfolded is between 1500 mm and 1650 mm.

[0007] Furthermore, the number of the filter element pleat units is 50 to 60.

[0008] Furthermore, the number of the filter element pleat units is 53 to 57.

[0009] Furthermore, after the plurality of filter element pleated units are folded and arranged, they are formed into a loose shape through heat curing.

[0010] Furthermore, the filter paper assembly comprises at least two layers of filter paper units stacked together, a plurality of filter holes are arranged on the surface of the filter paper unit, and the filter holes of the two layers of filter paper units are staggered.

[0011] Compared with the prior art, the present invention has the following advantages: the filter element of the present application is designed as a plurality of filter element pleated units, which can increase the filtration contact area; the filter paper assembly includes at least two layers of filter paper units stacked together, and the filter holes of the filter paper units are staggered, which can increase the filtration contact area while improving the penetration effect.

[0017] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below with reference to the accompanying drawings.

[0018] like Figure 1-Figure 3 As shown, a filter element adopting a folded filter paper arrangement structure includes a filter element assembly, the filter element assembly includes a filter element frame 1 and a filter paper component 2 installed in the filter element frame, the filter paper component 2 includes a plurality of continuously folded filter element pleated units 21, and the filter element pleated unit 21 includes two filter element paper edges 211, and the outer ends of the two filter element paper edges are bent transitions.

[0019] The number of filter element pleated units 21 is 50 to 60, with a preferred number being 53 to 57. The total length of the filter paper assembly 2 when unfolded is between 1500 mm and 1650 mm. Compared to traditional filter paper, the present invention utilizes a plurality of continuously folded filter element pleated units 21, increasing the filter paper's filtration contact area within the same circular structure.

[0020] like Figure 4 As shown, the filter paper assembly 2 comprises at least two stacked filter paper units 22. The filter paper units 22 have a plurality of filter holes 23 arranged on their surfaces. The filter holes 23 of adjacent filter paper units 22 are staggered to enhance permeability. Several filter element pleated units 21 are folded and arranged, then heat-cured into a loose shape.

[0021] The specific production process involves stacking several layers of filter paper units 22, folding the stacked filter paper assembly 2 into several filter element pleated units 21, and then heat-curing them in a loose, controlled temperature of 150°C ± 5°C for 45-50 minutes. The filter element pleated units 21 should be neatly folded, with smooth creases and no distortion, wrinkles, or delamination.
