[0033] like Figure 1 , Figure 2 As shown, an embodiment of this disclosure provides a filter element installation fixture 100, which includes a mounting base 10, a guide member 20, and a lifting mechanism 30. The mounting base 10 has a plurality of filter mounting portions 101 for mounting a filter 200. The bottom of the guide member 20 is provided with a filter positioning portion (not shown in the figure), and the top of the guide member 20 is provided with a filter element guide hole 201. The filter element guide hole 201 penetrates the guide member 20 along the thickness direction of the guide member 20. When the guide member 20 is installed on the filter 200, the filter element guide hole 201 and the filter element mounting hole (not shown in the figure) of the filter 200 are coaxially connected. The output end of the lifting mechanism 30 is located above the mounting base 10, and the output end of the lifting mechanism 30 can reciprocate linearly towards or away from the mounting base 10 along the height direction of the filter element installation fixture 100.

[0034] The filter element installation fixture 100 disclosed herein includes a mounting base 10, a guide member 20, and a lifting mechanism 30. The mounting base 10 has a plurality of filter mounting portions 101 for installing filters 200, so as to fix a plurality of filters 200 that need to be installed with filter elements 300. The guide member 20 is used to guide the filter elements 300 by being installed on the top of the filters 200. The guide member 20 has a filter element guide hole 201 for guiding the filter elements 300. The guide member 20 is fixed on the top of the filters 200 to guide the filter elements 300. When it is necessary to install the filter element 300 inside the filter 200, firstly, multiple filters 200 are installed inside the filter mounting portion 101 of the mounting base 10; then, the guide member 20 is installed on the top of the filter 200, so that the filter element guide hole 201 of the guide member 20 is coaxially connected with the mounting hole of the filter 200; finally, the output end of the lifting mechanism 30 is moved towards the mounting base 10 along the height direction of the filter element mounting fixture 100, and the output end of the lifting mechanism 30 contacts the end of the filter element 300 away from the guide member 20 and pushes the filter element 300 towards the mounting hole of the filter 200, thereby installing the filter element 300 inside the filter 200. The filter 200 is fixed by the mounting base 10 to prevent displacement of the filter element 300 during installation, thus improving the stability of the filter 200 during installation. The guide 20 installed on the top of the filter 200 guides the filter element 300 to prevent misalignment during installation, thus improving the accuracy and stability of the filter element 300 installation and preventing damage to the filter element 300 during installation. The filter element 300 is pressed into the filter 200 by the output end of the lifting mechanism 30, which can improve the efficiency of filter element 300 installation and reduce the workload of operators.

[0035] In this embodiment, the filter mounting portion 101 is a mounting hole or mounting groove, which can be used to position the filter 200 to limit the movement or displacement of the filter 200. The filter mounting portion 101 can also be multiple protrusions, which are evenly arranged and spaced apart along the circumference of the filter 200 when the filter 200 is installed in the filter mounting portion 101.

[0036] In some embodiments of this disclosure, the guide member 20 has multiple filter positioning parts arranged at intervals. Correspondingly, the guide member 20 has multiple filter element guide holes 201, the number of which is the same as the number of filter positioning parts, and the filter element guide holes 201 are arranged in a one-to-one correspondence with the filter positioning parts. The guide member 20 is simultaneously installed on the top of multiple filters 200 through the multiple filter positioning parts, so that multiple filter elements 300 can be installed in the corresponding multiple filters 200 through the guide member 20. Specifically, in this embodiment, the guide member 20 has four filter positioning parts and four filter element guide holes 201. First, the guide member 20 is installed on the top of four filters 200 on the mounting base 10 through the four filter positioning parts. Then, four filter elements 300 are installed in the four filter element guide holes 201 of the guide member 20 respectively. Finally, the lifting mechanism 30 presses the four filter elements 300 into the mounting holes of the filters 200 simultaneously, thereby realizing the simultaneous installation of the four filter elements 300 and improving the installation efficiency of the filter elements 300. Specifically, the filter positioning part is a positioning hole so that the guide 20 is fixed on the top of the filter 200.

[0037] In some embodiments of this disclosure, the filter element mounting fixture 100 further includes a pressure-bearing member 40, which covers the top of the filter element 300 when the filter element 300 is mounted on the guide member 20. The output end of the lifting mechanism 30 moves toward the mounting base 10, contacts the pressure-bearing member 40, and presses the pressure-bearing member 40 toward the mounting base 10, so that the filter element 300 below the pressure-bearing member 40 moves along the filter element guide hole 201 of the guide member 20 until the filter element 300 is completely inserted into the filter 200.

[0038] In some embodiments of this disclosure, the lifting mechanism 30 includes a hydraulic press 31 and a telescopic rod 32. The hydraulic press 31 is driven by the telescopic rod 32 to reciprocate linearly along the height direction of the filter element mounting fixture 100. The output end of the lifting mechanism 30 is the telescopic rod 32, which is driven by the hydraulic press 31 to move towards or away from the mounting base 10 along the height direction of the filter element mounting fixture 100. Specifically, when the filter element 300 needs to be installed, the filter 200 is installed on the mounting base 10. The top of the filter 200 is provided with a guide 20. Part of the filter element 300 is located in the filter element guide hole 201 of the guide 20. The press drives the telescopic rod 32 to move toward the mounting base 10. The end of the telescopic rod 32 away from the hydraulic press 31 contacts the filter element 300 to push the filter element 300 along the filter element guide hole 201 of the guide 20 toward the mounting hole of the filter 200. As the hydraulic press 31 continues to control the telescopic rod 32 to move toward the mounting base 10, the filter element 300 is completely pressed into the mounting hole of the filter 200 by the telescopic rod 32, thereby realizing the pressing of the filter element 300 into the filter 200. When the filter element 300 is installed, the hydraulic press 31 drives the telescopic rod 32 to move away from the mounting base 10 along the height direction of the filter element installation fixture 100, so that the space between the telescopic rod 32 and the mounting base 10 is large enough to facilitate the removal of the filter 200 after the filter element 300 is installed from the mounting base 10.

[0039] In other embodiments of this disclosure, the lifting mechanism 30 may also be a structure combining a motor, gears, and racks. The motor drives the gears to rotate, and the gears drive the racks meshing with them to move, thereby enabling the output end of the lifting mechanism 30 to move toward or away from the mounting base 10.

[0040] In some embodiments of this disclosure, the filter element mounting fixture 100 further includes a support assembly 50, one end of which is connected to the mounting base 10, and the other end of which is connected to the lifting mechanism 30. The support assembly 50 supports the lifting mechanism 30 above the mounting base 10, so that there is a certain installation space between the lifting mechanism 30 and the mounting base 10, which facilitates the installation of the filter 200 and the filter element 300.

[0041] Specifically, the support assembly 50 includes a support member 51 and a top plate 52. One end of the support member 51 is connected to the mounting base 10, and the end of the support member 51 facing away from the mounting base 10 is connected to the top plate 52. The lifting mechanism 30 is connected to the top plate 52. The support member 51 connects the mounting base 10 and the top plate 52. The mounting base 10 can provide a certain support for the top plate 52, that is, the mounting base 10 provides stable support for the lifting mechanism 30, so that the lifting mechanism 30 can stably press the filter element 300, improving the pressing accuracy and the reliability of installation. Specifically, the support member 51 extends along the height direction of the filter element mounting fixture 100, that is, along the height direction of the filter element mounting fixture 100, the mounting base 10 and the top plate 52 are respectively located at both ends of the support member 51, so that the mounting base 10 and the top plate 52 have sufficient installation space in the height direction of the filter element mounting fixture 100.

[0042] In some embodiments of this disclosure, two support members 51 are disposed at opposite ends of the mounting base 10, that is, two support members 51 are spaced apart at both ends of the mounting base 10, and the two spaced support members 51 are respectively connected to both ends of the top plate 52. By using two spaced support members 51, the reliability and stability of the connection between the mounting base 10 and the top plate 52 can be improved. At the same time, the two support members 51 can make the force on both ends of the mounting base 10 more even, and the two support members 51 can prevent the top plate 52 from being subjected to concentrated stress, thereby improving the service life of the top plate 52.

[0043] Specifically, each end of the mounting base 10 has a connecting protrusion, and each connecting protrusion has a connecting hole 102. The end of the support member 51 facing away from the top plate 52 is inserted into the connecting hole 102 to achieve the connection between the support member 51 and the mounting base 10. Furthermore, the support member 51 and the connecting hole 102 are interference fit to ensure the reliability of the connection between the support member 51 and the mounting base 10.

[0044] In some embodiments of this disclosure, at least one end of the top plate 52 is provided with a snap-fit ​​portion 521, and the support member 51 is provided with a locking portion 511, with the snap-fit ​​portion 521 engaging with the locking portion 511. The engagement of the snap-fit ​​portion 521 and the locking portion 511 enables a detachable connection between the support member 51 and the top plate 52. Specifically, one end of the top plate 52 is provided with a snap-fit ​​portion 521, or both ends of the top plate 52 are provided with snap-fit ​​portions 521.

[0045] In some embodiments of this disclosure, each end of the top plate 52 is provided with at least two latching portions 521, which are spaced apart along the length of the top plate 52 at that end. The engaging portion 511 of the support member 51 can be engaged and connected with any one of the at least two latching portions 521 at the corresponding end. Those skilled in the art can select one latching portion 521 of the top plate 52 to connect with the corresponding engaging portion 511 of the support member 51 based on the length dimension of the mounting base 10.

[0046] In some embodiments of this disclosure, the latching portion 521 is an open latch, and the engaging portion 511 is an annular groove provided on the outer wall of the support member 51. The annular groove enters the latch from the opening of the open latch and is confined within the latch, achieving a latching connection between the latch and the annular groove. When it is necessary to disengage the latch from the annular groove, the annular groove is moved from inside the latch towards the opening until it disengages from the opening of the latch. Furthermore, the dimension of the annular groove along the length direction of the support member 51 is equal to or equivalent to the thickness of the top plate 52 to prevent the annular groove from moving within the latch along the length direction of the support member 51, ensuring the reliability of the connection between the latch and the annular groove.

[0047] In some embodiments of this disclosure, a groove 522 is provided between the two ends of the top plate 52, the groove 522 extending along the length of the top plate 52, and the lifting mechanism 30 is slidably connected to the groove 522. The lifting mechanism 30 can move along the groove 522 through the slidably connected groove, that is, along the length of the mounting base 10, so as to press the filter element 300 on the filter 200 at different positions of the mounting base 10, thereby improving the installation efficiency of the filter element 300.

[0048] In some embodiments of this disclosure, both the top plate 52 and the mounting base 10 are plate-shaped structures. The top plate 52 and the mounting base 10 can also be other shapes, as long as the top plate 52 can be slidably connected to the lifting mechanism 30 and the mounting base 10 is provided with multiple filter mounting parts 101. The support member 51 is a column, and the support member 51 can also be other shapes, as long as it can connect the mounting base 10 and the top plate 52.
