Energy-saving oil filter with replaceable filter element

Abstract

The invention relates to an energy-saving oil filter with replaceable filter element, belonging to the field of a filter. The energy-saving oil filter mainly solves the problem that a filtering component of a filter element assembly can be replaced, and is provided with a connecting seat shell assembly provided with medium inlets (3) and (5); and the filter element assembly is formed by processing the filter element (10) attached on a metal inner mesh (11) and an upper and a lower sealing covers (20) and (21) into a whole. The filter element assembly is assembled on a tubular cylinder oil return pipe (12), and is fixed by a hexagon nut through sealing rings (15) and (16); the upper end thread part of the tubular cylinder oil return pipe (12) and a locating pin (7) are fixed at the rear end of thread where connecting seat shells are connected with an engine oil seat (4); then, an outer cylinder body (9) is sheathed on the sealing rings of the connecting seat shells (1) and (6), a center hole (24) of the outer cylinder body is provided with special front end external circle inner thread, and the rear end is internally provided with an inner four-angle blind hole nut (18); a sealing ring (19) and a rotating nut (18) are pressed and firmly fixed with the front end thread part of the tubular cylinder oil return pipe (12); meanwhile, the outer cylinder body (9) is compressed and closely jointed with the connecting seat shell (1). A number of outer spline steps (28) on the outer cylinder body are matched with a number of inner spline steps (38) on the connecting seat shells.

Description

technical field [0001] The invention belongs to the field of filters, and relates to an energy-saving oil filter with a replaceable filter element. Background technique [0002] In motor vehicles and electromechanical equipment, most of them need filters for filtering the required fuel oil and lubricating oil, especially in motor vehicles; as far as the existing motor vehicle oil filters are concerned, Most of them are integral structures, that is, the filter element assembly is fixed in the shell formed by the filter-related cover assembly and the shell assembly, forming an integrated overall structure. The filter seat of the equipment - referred to as the filter seat is connected together, and the medium inlet and outlet are naturally connected to each other. Its advantage is that it is convenient to replace. The cost is high. In addition, because the oil attached to the used filter is difficult to remove, and it is difficult to disassemble the material for classification...

Problems solved by technology

[0002] In motor vehicles and electromechanical equipment, most of them need filters for filtering the required fuel oil and lubricating oil, especially in motor vehicles; as far as the existing motor vehicle oil filters are concerned, Most of them are integral structures, that is, the filter element assembly is fixed in the shell formed by the filter-related cover assembly and the shell assembly, forming an integrated overall structure. The filter seat of the equipment - referred to as the filter seat is connected together, and the medium inlet and outlet are naturally connected to each other. Its advantage is that it is convenient to replace. The cost is high. In addition, because the oil attached to the used filter is difficult to remove, and it is difficult to disassemble the material for classification and recycling, so it can only be used as a waste landfill, which is not only a huge waste of resources, but also has great harm to the natural environment; The filter element in the assembly is glued together with the mounting and dismounting parts of the upper and lower glands of the bracket, which is easy to crack during use and easily affects the filtering quality. In the existing invention patent ZL02289422.5, the filter element can be replaced. It is only a fuel filter, and the structure is complex, many parts are required, and it is inconvenient to assemble and disassemble. It is only an improvement on the traditional fuel filter.

[0003] At present, there is no energy-saving oil filter with replaceable filter elements in China.
