Diesel oil filtering device

Abstract

The invention discloses a diesel oil filtering device, which comprises a shell and a filter core, wherein the shell comprises an upper cover, a lower cover and an inner protective net, the upper coverand the lower cover are installed at the upper end and the lower end of the inner protective net respectively, the filter core is a cylinder with a through groove in the middle, the inner protectivenet is arranged in the through groove in a sleeved mode, and the cylinder is integrally formed, and is provided with a micropore structure. According to the invention, the filter core is integrally formed and is provided with the micropore structure, so that the density of through holes is more uniform, the filtering precision is high, the filtering flow is large, the pressure difference is small,the filtering efficiency is stable, the chemical compatibility is strong, the corrosion resistance, strong acid resistance, strong alkali resistance and organic solvent resistance are realized, the dirt holding capacity is strong (the relative area proportion between a solid and the filter core is relatively improved), the deformation resistance is high (the rigidity is high and the relative deformation degree is high after integral forming), the oil-water separation effect is obvious, the service life is long, the cost is low, and other advantages are achieved.

Description

technical field [0001] The invention relates to the technical field of filter element devices, in particular to a diesel filter device. Background technique [0002] The diesel filter element can effectively block the fine dust and moisture in the diesel oil, and can effectively prolong the service life of the fuel injection pump, diesel nozzle and other filter elements. Large and small oil droplets, large oil droplets are easy to separate through the oil and gas separator, while small oil droplets (suspended oil particles) must be filtered through the micron glass fiber layer of the oil and gas separation filter. When the diameter and thickness of the glass fiber are correctly selected, the filter material can intercept, diffuse and aggregate the oil mist in the gas, and the effect can reach the best. Small oil droplets quickly gather into large oil droplets, which pass through the filter layer under the push of pneumatic and gravity, accumulate at the bottom of the filter...

AI Technical Summary

Problems solved by technology

The processing technology of the folded filter element is complicated, there are many procedures, the production efficiency is relatively low, the cost is high, it is not environmentally friendly, the quality risk is high, and the gap between adjacent paper sheets is large.

And with the national five and six automobile exhaust emission standards, the filtration accuracy of diesel filter devices is getting higher and higher, and the existing folded filter elements cannot meet the existing emission requirements

[0004] At the same time, the existing shells are generally made of metal materials, and there is a certain amount of moisture in the diesel oil, so the shells have the risk of rusting, and may cause secondary pollution to diesel oil, reducing the filtering effect
