Abstract

The invention discloses a two-stage integrated composite filter element for oil product filtering.The two-stage integrated composite filter element comprises an upper end cap, a lower end cap, a framework, folding filter paper and a polyamide filter material, the framework comprises an inner protection tube and an outer protection tube which are arranged coaxially, the upper end cap and the lower end cap are fixed at two shaft ends of the folding filter paper and the polyamide filter material, at least one oil outgoing hole is formed in each of the upper end cap and the lower end cap, the folding filter paper is connected on the outer ring of the inner protection tube in a sleeved manner, the polyamide filter material is connected on the outer ring of the outer protection tube in a sleeved manner and obtained by treating a polyamide material through a melt-blowing process, superfine fibers which are melt-blown out are made into polyamide melt-blown nonwoven cloth through mutual binding and winding, the polyamide melt-blown nonwoven cloth is of a loose structure, and filter holes different in hole diameter are formed in the polyamide melt-blown nonwoven cloth.The two-stage integrated composite filter element is ensured to be resistant to oil and alcohol corrosion, has high filtering accuracy, pollution bearing capability and oil-water separating capability and meets filtering requirements of common oil products.

Description

technical field [0001] The invention relates to a filter material, a preparation device and a preparation method thereof, in particular to a composite filter element of polyamide melt-blown non-woven fabric and pleated filter paper used for oil products. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, resulting in increased fuel consumption and a sharp increase in exhaust emissions after the fuel engine has been used for a period of time. The current general solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the fuel to make the fuel clean. Clean fuel can ...
