Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a centrifugal fuel filter. Background Art

[0002] A centrifugal fuel filter utilizes centrifugal force to effectively separate impurities and particles from fuel. High-speed rotation generates centrifugal force, which flings impurities and particles from the fuel onto the filter walls, thereby purifying the fuel. This filter offers stable performance, requires no filter element replacement, and offers low maintenance costs, requiring only regular cleaning of impurities deposited on the filter walls. Furthermore, centrifugal fuel filters effectively remove harmful particles and moisture from the fuel, protecting the fuel system, reducing wear and clogging, improving fuel purity and quality, and ensuring proper engine operation. Consequently, they are widely used in a variety of fields, including automotive, machinery, and petroleum.

[0003] During factory installation, professional mechanical equipment will be used to install the rotor filter element. However, when replacing it, many users do not drive the vehicle to the factory for replacement. They usually replace it in a familiar auto repair shop. In order to facilitate replacement, the manufacturer will set a polygonal shape on the outer wall of the filter so that maintenance workers can screw the threads when disassembling and installing.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: since the disassembly tools of ordinary repair shops are not as precise as those of the original factory, there will be a large number of slippage phenomena during disassembly, resulting in the inability to disassemble. In many cases, workers will choose destructive disassembly. Although the disassembly can be completed, during installation, since the tools are not professional rotary tools, the installation tightness cannot reach the original tightness, which brings certain hidden dangers in use. Utility Model Content

[0005] The main purpose of the utility model is to provide a centrifugal fuel filter, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A centrifugal fuel filter comprises a rotor filter element and a U-shaped lever. The top and bottom ends of the outer wall of the rotor filter element are both provided with a polygonal rotation area. A plurality of opposite end blocks are vertically provided on the polygonal rotation area. The front sides of the end blocks are each provided with a first screw groove. Both ends of the U-shaped lever are fixed with a plug plate. Both ends of the plug plate are fixed with an ear plate. Both ear plates are provided with a second screw groove. The interior of the second screw groove is penetrated by a hexagonal bolt.

[0008] Preferably, one end of the hexagonal bolt passes through the second screw groove and is inserted into the interior of the first screw groove and threadedly connected thereto.

[0009] Preferably, the plug-in plates are respectively inserted between two end blocks at matching positions, and the top and bottom of the plug-in plates are respectively in contact with the side close to the end blocks.

[0010] Preferably, the ear plate and the end block are in contact with each other at their adjacent sides.

[0011] Preferably, the side of the inserting plate away from the hexagonal bolt contacts the side wall of the polygonal rotation zone at the matching position.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Multiple opposite and vertical end blocks are respectively provided at the positions of the two polygonal rotation zones, which can be assembled with the lugs of the plug plates through hexagonal bolts, and the rotor filter element is rotated by applying force through the U-shaped lever between the plug plates. This method can greatly solve the problem of difficult disassembly and assembly due to slipping, making disassembly and assembly simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, the centrifugal fuel filter includes a rotor filter element 1 and a U-shaped lever 6. The top and bottom ends of the outer wall of the rotor filter element 1 are provided with a polygonal rotation area 2. The polygonal rotation area 2 is vertically provided with a plurality of opposite end blocks 3. The front side of each end block 3 is bored with a screw groove 1 31. Both ends of the U-shaped lever 6 are fixed with a plug plate 4. Both ends of the plug plate 4 are fixed with an ear plate 41. The ear plate 41 is bored with a screw groove 2 411. The interior of the screw groove 2 411 is penetrated by a hexagonal bolt 5.

[0021] Specifically, one end of the hexagonal bolt 5 passes through the second screw groove 411 and is inserted into the interior of the first screw groove 31 and threadedly connected thereto.

[0022] Specifically, the insert plates 4 are respectively inserted between the two end blocks 3 at matching positions, and the top and bottom of the insert plates 4 are respectively in contact with the side close to the end blocks 3, the ear plates 41 are in contact with the side close to the end blocks 3, and the side of the insert plates 4 away from the hexagonal bolts 5 is in contact with the side wall of the multilateral rotation zone 2 at the matching position, which can better drive the rotor filter element 1 to rotate.

[0023] Working principle: When disassembling, insert the plug plate 4 between the two end blocks 3 that are perpendicular to the top and bottom ends. The plug plate 4 is respectively fitted with the multilateral rotation area 2 and the end block 3, and the ear plate 41 is fitted with the end block 3. Then the hexagonal bolt 5 passes through the second screw groove 411 and is threadedly connected with the first screw groove 31. Then, a rotating force is applied to the U-shaped lever 6 so that it can easily drive the rotor filter element 1 to rotate. If the installation area is blocked by other components, the hexagonal bolt 5 can be removed, and the U-shaped lever 6 and the plug plate 4 can be installed in an unobstructed position and re-rotated, so that the rotor filter element 1 will not slip when disassembling.

[0024] The circuits, electronic components and control modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.
