[0001] The utility model belongs to the technical field of fluid filtration, especially relates to a split basket filter basket assembly and basket filter. BACKGROUND

[0002] In order to ensure oil quality, in the civil aviation airport oil depot, the basket filter is indispensable equipment. The basket filter adopts the traditional metal wire mesh as the filter medium, and can effectively remove the impurity particles in the oil. According to the implementation rules of'civil aviation fuel quality control and operation procedure'MH / T6020-2012, personnel need to check the basket filter and basket net every year or when the pressure difference before and after the basket filter exceeds 0.05Mpa. However, the basket net in the traditional basket filter is relatively large in size and heavy in weight. When cleaning and replacing the basket net, not only time is consumed, but also the labor intensity is large. In addition, due to the relatively large size of the basket net, its installation and maintenance are relatively complex. SUMMARY

[0003] In view of the above problems, the present application provides a split basket filter assembly, which comprises a circular plate frame, and a plurality of independent basket nets are arranged on the circular plate frame.

[0004] The plurality of independent basket nets are open hollow cylindrical structures, comprising a bottom wall and a peripheral wall, and a plurality of filter holes are uniformly arranged on the bottom wall and the peripheral wall.

[0005] Further, the upper end opening position of the independent basket net extends outward to form a mounting edge, and the circular plate frame is formed with a groove matched with the mounting edge.

[0006] Further, the independent basket net is installed on the circular plate frame through a buckle, the buckle comprises a buckle seat and a buckle head, the buckle head is fixedly installed on the mounting edge of the independent basket net, and the buckle seat is fixedly installed on the circular plate frame at the periphery of the groove.

[0007] Further, a plurality of first threaded holes are arranged on the mounting edge of the independent basket net, a plurality of second threaded holes are arranged on the corresponding position of the groove of the circular frame, and the independent basket net and the circular frame are fixedly connected through bolts penetrating the first threaded holes and the second threaded holes.

[0008] Further, the circular plate frame gradually decreases from the outer edge to the center part, forming a funnel-shaped structure.

[0009] Further, the surface of the circular plate frame is smooth.

[0010] Further, the number of the independent basket nets is at least 3.

[0011] Another aspect of the present application provides a basket filter comprising any of the split basket filter basket assembly described above.

[0012] The beneficial technical effects of the present application are:

[0013] The basket assembly of the conventional basket filter is improved into the independent split structure in the present application.

[0021] The following examples further illustrate the content of the present application, but should not be understood as limiting the present application. Any modification or replacement of the method, steps or conditions of the present application without departing from the spirit and essence of the present application shall fall within the scope of the present application.

[0022] In some embodiments, as Figure 1 and he Figure 2As shown, the present application provides a split basket filter assembly for use in the basket filter of the oil depot of a civil airport, which comprises a circular plate frame 1 having a certain thickness, and a plurality of through holes 101 formed on the circular plate frame. The split basket filter assembly of the present application further comprises a plurality of independent basket nets 2, which are all open hollow cylindrical structures comprising a bottom wall and a peripheral wall, and a plurality of filter holes 201 uniformly formed on the bottom wall and the peripheral wall. The independent basket nets 2 and the through holes 101 of the circular plate frame 1 are in one-to-one correspondence, and the number of the independent basket nets 2 matches the number of the through holes 101, and the outer diameter of the independent basket nets 2 matches the inner diameter of the through holes 101, and the independent basket nets are installed in the through holes 101.

[0023] When the basket filter is in operation, the two sides of the circular plate frame 1 are respectively an oil inlet and an oil outlet, and the oil flows through the oil inlet to the circular plate frame 1, and then the oil is filtered through the filter holes 201 of each independent basket net 2. Due to the structural design of the independent basket net 2, the impurity particles in the oil are effectively intercepted, and the clean oil is discharged through the filter holes of the independent basket net. The split design of the independent basket net 2 allows the staff to quickly disassemble the independent basket net 2 from the circular plate frame 1 for individual cleaning or replacement when maintenance is required. This design not only reduces the time required for maintenance, but also reduces the labor intensity and improves the maintenance efficiency of the basket filter. In addition, since the volume and weight of each basket net are relatively small, the installation and disassembly process is more convenient, thereby further improving the operation simplicity of the entire filtration system.

[0024] In some embodiments, as shown in Figure 3 The upper end opening position of the independent basket net 2 extends outward to form a mounting edge 202, a groove is formed on the circular plate frame to match the mounting edge, and a sealing ring is installed between the mounting edge and the groove.

[0025] In order to prevent the oil from flowing directly from the oil inlet to the oil outlet without being filtered by the independent basket net 2, a sealing ring is installed between the mounting edge 202 of the independent basket net 2 and the groove of the circular plate frame 1, which prevents the oil from leaking through the gap between the mounting edge 202 of the independent basket net 2 and the groove of the circular plate frame 1, and ensures that the oil must be filtered through the filter holes of the independent basket net 2. The use of the sealing ring not only improves the reliability of the filtration. In addition, the material selection of the sealing ring needs to consider oil resistance and temperature resistance to adapt to the high temperature environment that may occur during the oil filtration process.

[0026] In some embodiments, as shown in Figure 3 The independent basket net 2 is installed on the circular plate frame by a buckle 3, which comprises a buckle seat 301 and a buckle head 302, the buckle head 302 is fixedly installed on the mounting edge 202 of the independent basket net 2, and the buckle seat 301 is fixedly installed on the circular plate frame 1 outside the groove 102.

[0027] The buckle head 302 and the independent basket 2 can be fixed and installed by means of welding, bonding, screwing, etc., which are not limited in this application.

[0028] The buckle 3 in this application uses an existing buckle, such as the clasp in the patent document with application number CN202420101600.6. Its specific structure will not be described in detail here. When the buckle seat 301 and the buckle head 302 are engaged, the independent basket 2 is fixed to the circular frame 1. This buckle 3 design makes the installation and removal of the basket more convenient, and the structural design of the buckle 3 ensures that the basket will not shift during the filtration process, guaranteeing the stability of the filtration.

[0029] In some embodiments, such as Figure 1 As shown, another installation method is provided between the independent basket 2 and the circular frame 1. The independent basket has several first threaded holes along its mounting edge 202, and the circular frame 1 has several second threaded holes at corresponding positions in its groove 102. The independent basket and the circular frame are connected and fixed by bolts 3 passing through the first and second threaded holes. This bolted connection provides a more robust fixation and is suitable for filters operating in high-pressure or high-flow environments. The bolted connection ensures that the basket will not loosen under significant pressure, thus guaranteeing the stability of the filtration effect and the safety of the filtration system. Furthermore, the maintenance and replacement process of the bolted connection is relatively simple, facilitating routine maintenance by operators.

[0030] In some embodiments, to ensure that the filtering effect of the improved net is not compromised, the number of individual nets is at least four.

[0031] Taking a practical application as an example, the original filter basket used in civil aviation airport oil depots was a hollow cylinder without a lid, with a bottom diameter of 1 meter and a height of 1.2 meters, and its filtration area was approximately 4.5 square meters. After being improved to the detachable filter basket assembly of this application, the bottom diameter of a single independent basket is approximately 0.3 meters, and the filtration area of ​​a single independent basket is approximately 1.14 square meters. Therefore, the number of independent baskets is set to at least 4 to ensure that the filtration area is not less than that of the original basket. This ensures both filtration efficiency and ease of maintenance and replacement. Although the filtration area of ​​each independent basket is reduced, the total filtration area is maintained or even exceeded due to the increase in the number of baskets. The detachable design of the basket in this application makes the weight and volume of each independent basket relatively small, thereby making the installation and disassembly of the entire filtration system more convenient and quick.

[0032] In some embodiments, in order to improve the filtering efficiency, the circular plate frame is gradually lowered from the outer edge to the center part, forming a funnel structure, and the surface of the circular plate frame is provided with a smooth surface, so that when the oil flows through the circular plate frame, it helps to reduce the resistance of the oil during the filtering process, making the oil flow more smoothly and improving the filtering efficiency.

[0033] In another aspect, as shown in the drawings, the application provides a basket filter mounted with the split basket filter basket assembly of any of the above. Figure 5 The basket filter of the application includes an inlet 4 and an outlet 5. In actual application, the oil enters the basket filter from the inlet 4, passes through the through holes 101 on the circular plate frame 1 in the split basket filter basket assembly of the application, enters each independent basket for filtering, and then the clean oil is discharged from the outlet 5.

[0034] Although the utility model has been described in detail above with general description, specific embodiments and tests, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model belong to the scope of protection required by the utility model.
