Problems solved by technology

The filter material of non-woven fabric can be cleaned with alkaline water and can be used repeatedly, but it is still unavoidable that the non-woven fabric has large pores and the leaked dust damages the engine
[0009] There is a well-known filter material on the market that uses polyester-coated needle-punched felt. It uses polytetrafluoroethylene to coat polyester or glass fiber cloth. It belongs to the surface layer filtration method and has a certain effect of not sticki...

Embodiment 1

[0030] figure 1 It is a non-stick ash fiber depth filter element designed according to the above method, which is composed of a wound fiber bundle 1 and a porous cylinder 2.

[0031] figure 2 is the porous cylinder 2, image 3 is the entangled fiber bundle 1 .

[0032] The fiber bundle 1 with dust-free performance is wound on a porous cylinder 2 to form a cylindrical filter element, and the air flows in from the periphery of the cylindrical filter element and flows out from the inner hole of the cylindrical filter element, or vice versa. Outflow from the inner hole.

[0033] In order to prevent the fiber bundle from spreading, the winding can be staggered into a flower shape; the periphery of the filter element can be cleaned with water or high-pressure airflow; the tightness and thickness of the winding layer depends on the filtration accuracy.

[0034] The dust-free performance fiber can be a material that reduces the surface energy by compounding a layer on the ordinar...

Embodiment 2

[0038] Figure 4 It is a kind of non-stick gray fiber depth filter element designed according to the above method, which is composed of fiber cloth 3 and porous cylinder 2. Weave the fiber bundle 1 with dust-free performance into fiber cloth 3, then wind the fiber cloth on the porous cylinder 2 to form a cylindrical filter element, the air flows in from the periphery of the cylindrical filter element, and the The inner hole of the filter element flows out, or vice versa, preferably the periphery flows in and the inner hole flows out. The weaving tightness of the fiber cloth and the thickness of the winding layer depend on the filtration accuracy.

[0039] The method of obtaining the dust-free performance fiber is the same as above.

Abstract

The invention provides a dust-free fiber deep filtration filter element. The filter element comprises a porous cylinder, wherein dust-free performance fibers which are high molecular fibers are wound on the outer circumference of the porous cylinder; a material for reducing surface energy is compounded on the high molecular fibers; the high molecular fibers can be polypropylene fibers or polyester fibers; and the material for reducing the surface energy can be polytetrafluoroethylene, organic silicon or fluororesin. The filter element has the characteristics that a high molecular fiber filter material has high air permeability and is convenient to clean, achieves the equivalent effects of a paper filter material with small filter gaps by using the dust-free characteristic of the dust-free performance fibers, and has high air permeability; effective filter area is reduced, and the overall volume of the filter element is reduced; a large-aperture air channel is formed by gaps among the fibers; due to a multi-layer structure, deep filtration is realized, and the dust storing and blocking capability is improved; and the probability that the filter material is blocked is reduced, and the service life of the filter element is prolonged.

Description

technical field [0001] The invention relates to the field of air filters for internal combustion engines, in particular to a non-stick ash fiber deep filter element. Background technique [0002] The core component of the car air filter is the filter element. The main raw material of the filter element is the filter material. The main requirements for the filter material are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. [0003] The existing car air filter element generally uses paper folded filter material, which is characterized by surface layer filtration, small filter pores, and high filtration accuracy. The disadvantage is that the paper filter element is inconvenient to clean. Due to the small pores, it has to be folded Increase the working area of ​​the filter element to achieve the required channel area, which increases the volume of the product. At the same time, the small pores are also easy to block, resu...
