Universal rotation type filter utilizing polyamide filter element

Abstract

The invention discloses a universal rotation type filter utilizing a polyamide filter element. The universal rotation type filter comprises a shell and the filter element arranged in the shell. The filter element comprises an upper end cover, a lower end cover, filter paper and a polyamide melt-blown filter material. A thread connecting plate is arranged at an opening part of the shell. A plurality of oil inlet through holes are formed in the periphery of a thread connecting plate thread through hole. An oil product entering from a filter base oil inlet pipe enters the part between the shell and the filter element through the oil inlet through holes of the thread connecting plate. A plurality of symmetrically-distributed protruding teeth are arranged on the outer edge of the thread connecting plate. Grooves matched with the protruding teeth are formed in the opening part of the shell. The circumferential size of the protruding teeth is smaller than that of the grooves. A supporting structure is arranged at the bottom of the shell, and under the effect of the supporting structure, the thread connecting plate is pressed and attached to the part between the opening part of the shell and a filter element oil outlet. The universal rotation type filter solves the problem that a filter element in an existing filter shell cannot be replaced, has the beneficial effects of being high in dirt containing capability, high in filtering precision and the like, and is suitable for filtering of various oil products.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to an oil filter, in particular to a filter with a replaceable filter core and other parts of the housing that can be reused. 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 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 oil to make the fuel clean. Clean fuel can improve combustion efficiency, thereby saving fuel ...
