Abstract

The invention discloses a polyamide filter element obtained through sweat soldering and a manufacturing method thereof. The polyamide filter element comprises an end cover, a lower end cover and a polyamide filter material. The polyamide filter material is of a hollow cylinder structure formed by processing polyamide materials through a melt-blowing technology, and bonding and twining blown-out superfine cellosilk. The filter material is of a loose structure and is provided with filter holes of different hole diameters. The hole diameter of the filter holes is gradually decreased from the outer layer to the inner layer of the cylinder structure. The upper end cover and the lower end cover are welded to the two ends of the filter material through a hot-melt technology. The at least one of the upper end cover and the lower end cover is provided with an oil outlet hole. The filter element has the good filter precision, pollutant carrying capacity and flow resistance parameters on the premise of ensuring that the material has the oil resistance and alcohol corrosion resistance, non-glue connection is achieved by adopting the sweat soldering scheme, and the filter requirements of oil products, chemical waste liquid and chemical waste gas are met.

Description

technical field [0001] The invention relates to a filter material, a preparation device and a preparation method thereof, in particular to a polyamide filter element used for oil products and a preparation method thereof. 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 improve combustion efficiency, th...
