Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and in particular to a disc-type filter element. Background Technology

[0002] A filter cartridge is a key component used to filter and purify fluids. It removes impurities, particulate matter, and harmful substances from fluids through physical barriers, adsorption, and other methods to protect the normal operation of downstream equipment or systems and extend their service life.

[0003] Some filter cartridges used inside annular equipment employ the same annular arrangement, but require the installation of multi-layered filters to achieve better filtration results. During installation, the annular filter cartridges are simply stacked to perform multi-layered filtration.

[0004] However, when filter cartridges are stacked, their positions may deviate to a certain extent. Even if the stacked filter cartridges are squeezed and fixed, some gas or particles will still flow out along the gaps on both sides, resulting in a reduction in filtration effect. Therefore, this application proposes a disc-type filter cartridge. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a disc-type filter element, including a primary filter element 1. A connecting groove 5 is provided on one side of the primary filter element 1. A positive magnetic block 6 is fixedly connected inside the connecting groove 5. A negative magnetic block 8 is fixedly connected inside the connecting groove 5 near the positive magnetic block 6. The positive and negative magnetic blocks 6 and 8 are arranged in a "U" shape. The positive and negative pole structures of the positive and negative magnetic blocks 6 and 8 prevent repulsion between like poles during adsorption. An insertion sleeve 7 is slidably connected inside the connecting groove 5. A negative magnetic block 8 is fixedly connected to the side of the insertion sleeve 7 near the positive magnetic block 6. A positive magnetic block 6 is also fixedly connected to the side of the insertion sleeve 7 near the negative magnetic block 8 inside the connecting groove 5. A secondary filter element 15 is fixedly connected to the side of the insertion sleeve 7 away from the negative magnetic block 8. The positive magnetic block 6 and the negative magnetic block 8 attract the insertion sleeve 7 inside the connecting groove 5 by means of opposite pole attraction, thereby allowing the primary filter element 1 and the secondary filter element 15 to be installed without deviation.

[0024] in addition Figures 4-5 As shown, the primary filter element 1 has primary filter holes 13 inside, and multiple sets of primary filter holes 13 are arranged in a circumferential array. The primary filter holes 13 perform primary filtration. The secondary filter element 15 has secondary filter holes 14 inside, and the secondary filter holes 14 are arranged in a circumferential array. The secondary filter holes 14 perform secondary filtration. The primary filter holes 13 and secondary filter holes 14 are arranged in an alternating pattern. The intersection of the primary filter holes 13 and secondary filter holes 14 can increase the filtration effect. The secondary filter element 15 also has a connecting groove 5 on the side away from the insertion sleeve 7. The other side of the secondary filter element 15 can also be used to stack new filter structures. The primary filter element 1 is also fixedly connected to the insertion sleeve 7 on the side away from the secondary filter element 15. The primary filter element 1 can also be used as a secondary filter, thereby connecting with other filter structures.

[0025] in addition Figure 1 and Figure 2 As shown, the primary filter element 1 and the secondary filter element 15 have control ports 16 inside. A sliding groove 12 is formed inside the control port 16 near the positive magnetic block 6 and the negative magnetic block 8. A disassembly block 4 is slidably connected inside the sliding groove 12. The disassembly block 4 inside the sliding groove 12 can separate the positive magnetic block 6 and the negative magnetic block 8 that are attracted to each other inside the connecting groove 5. The disassembly block 4 is trapezoidal in shape, and the edge of the disassembly block 4 near the sliding groove 12 is rounded. The rounded trapezoidal structure of the disassembly block 4 makes it easier to embed into the positive magnetic block. Between the positive magnetic block 6 and the negative magnetic block 8, a push block 10 is fixedly connected to one side of the disassembly block 4. The push block 10 makes it easier to control the movement of the disassembly block 4. A reset spring 3 is fixedly connected to the side of the disassembly block 4 away from the sliding groove 12. A positioning tube 11 is fixedly connected to the end of the reset spring 3 away from the disassembly block 4. The reset spring 3 can push the disassembly block 4 to continuously abut between the positive magnetic block 6 and the negative magnetic block 8 on the side of the positioning tube 11, which is convenient for separating the positive magnetic block 6 and the negative magnetic block 8. A fixing component is provided on one side of the positioning tube 11.

[0026] also Figure 2 , Figure 3 As shown, the fixing component includes a positioning sleeve 2, which is fixedly connected to one side of the positioning tube 11. The outside of the positioning sleeve 2 is fixedly connected to the inside of the control port 16. The positioning sleeve 2 can fix the positioning tube 11 inside the control port 16. A telescopic rod 9 is fixedly connected to the side of the disassembly block 4 near the reset spring 3. The end of the telescopic rod 9 away from the disassembly block 4 is fixedly connected to the outside of the positioning tube 11. The telescopic rod 9 is set inside the reset spring 3. The telescopic rod 9 can assist the reset spring 3 in telescopic movement, and the telescopic rod 9 can also ensure that the position of the disassembly block 4 will not shift.

[0027] In this embodiment, the primary filter element 1 is first installed at the desired filtration position. Then, the insertion sleeve 7 of the secondary filter element 15 is aligned with the connecting groove 5 of the primary filter element 1. At this time, the negative magnetic block 8 and the positive magnetic block 6 on one side of the insertion sleeve 7 are attracted to the positive magnetic block 6 and the negative magnetic block 8 inside the connecting groove 5, thereby fixing the secondary filter element 15 and the primary filter element 1. Then, the primary filter hole 13 inside the primary filter element 1 and the secondary filter hole 14 inside the secondary filter element 15 intersect, thereby improving the filtration effect of the primary filter element 1 and the secondary filter element 15.

[0028] When the insert sleeve 7 is installed into the connecting groove 5, the negative magnetic block 8 and the positive magnetic block 6 on one side of the insert sleeve 7 will first squeeze the beveled surface of the disassembly block 4, so that the disassembly block 4 slides along the sliding groove 12, thereby allowing the disassembly block 4 to squeeze the reset spring 3 and the telescopic rod 9 to retract outside the positioning tube 11. The positioning tube 11 is fixed to the inner wall of the control port 16 by the positioning sleeve 2. When installing, the push block 10 can also be fitted into the required installation position.

[0029] After a period of use, the disassembly block 4 can be slid inside the sliding groove 12 by pushing the block 10. The rounded corner of the disassembly block 4 will be inserted along the gap between the positive magnetic block 6 and the negative magnetic block 8, thereby disengaging the negative magnetic block 8 and the positive magnetic block 6. In this way, the insertion sleeve 7 can be removed from the connection groove 5, thereby separating the primary filter element 1 and the secondary filter element 15.

[0030] It should be noted that this device uses the positive magnetic block 6 and negative magnetic block 8 inside the connecting groove 5 to attract the negative magnetic block 8 and positive magnetic block 6 on one side of the insertion sleeve 7, thereby connecting the primary filter element 1 and the secondary filter element 15. During disassembly, the positive magnetic block 6 and negative magnetic block 8 can be separated by the rounded trapezoidal structure of the disassembly block 4, thereby separating the primary filter element 1 and the secondary filter element 15. This achieves the effect of neat installation of the primary filter element 1 and the secondary filter element 15 and quick disassembly, solving the problem of gaps between the primary filter element 1 and the secondary filter element 15 caused by the single method of pressing and squeezing, which leads to cross-filtration effect. This improves the installation effect and filtration effect of the primary filter element 1 and the secondary filter element 15.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
