Description

Technical Field

[0001] This utility model relates to the field of natural gas filters, specifically to a filter element disassembly tool. Background Technology

[0002] Filters are an indispensable device in pipelines that transport media. Natural gas filter elements are suitable for separating impurities in natural gas. However, since filter elements are used for long-term filtration, they need to be disassembled and cleaned regularly, which requires the use of filter element disassembly tools.

[0003] Existing natural gas filters are difficult to disassemble and replace. Most are disassembled manually or by clamping the filter element with pliers. However, this method is not only cumbersome and laborious, but also increases the labor intensity of workers. The overall operation process is too long. In the long run, this not only prolongs the replacement time, but also increases the wear and tear cost of the filter element due to violent disassembly.

[0004] Therefore, it is necessary to invent a filter cartridge disassembly tool to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a filter element disassembly tool. The tool consists of a first clamping block and a second clamping block fitted around the outer ring of the filter element. Then, rotating the turntable drives the screw to rotate, which in turn pulls the lower sleeve to extend and retract. When the sleeve extends and retracts, it drives the external movable rod to pull the surrounding connecting blocks and the first clamping block inward, thereby clamping the filter element. Compared with directly clamping with pliers, this clamping method is not only more convenient but also avoids damage to the filter element, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filter element removal tool includes: a bracket for supporting the filter element removal tool;

[0008] The screw is installed inside the bracket and is used to adjust the clamping range according to the size of the filter element. A turntable is fixedly installed at the upper end of the screw, and a movable shaft is provided at the lower end of the screw. A sleeve is provided below the movable shaft, and a fixed frame is fixedly installed around the sleeve. A movable rod is movably connected inside the fixed frame.

[0009] A connecting block is set around the bottom of the bracket to clamp the filter element. A connecting shaft is set inside the connecting block and is movably connected to the movable rod. A fixing block is fixed below the connecting block, and a first clamping block is fixedly installed on one side below the fixing block.

[0010] The adjustment mechanism, installed below the fixed block, is used to adjust the size of the corners of the filter element being clamped.

[0011] Furthermore, a sleeve is fixedly installed below the bracket, and a tightening bolt is provided on one side of the sleeve.

[0012] Furthermore, a slide rail is fixedly installed around the lower perimeter of the bracket, and a slider is movably connected to the outside of the slide rail, with the connecting block installed below the slider.

[0013] Furthermore, the adjustment mechanism includes an adjustment bolt, a second clamping block, a spring, a limiting block, and a sliding groove. The adjustment bolt passes through the inside of the first clamping block, and one end of the adjustment bolt is movably connected to the second clamping block. A limiting block is fixedly installed above the second clamping block, and a sliding groove is provided on the lower inner surface of the fixed block.

[0014] Furthermore, spring clips are respectively provided inside the first clamping block and the second clamping block.

[0015] Furthermore, the upper limiting block of the second clamping block slides in a groove provided below the fixing block, and the limiting block and the groove are used in conjunction.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By setting up a bracket, screw, turntable, movable shaft, sleeve, fixed frame, movable rod, connecting block and first clamping block, the filter element can be clamped, making it easy for staff to directly pull out the filter element, thus improving convenience. The first clamping block and the second clamping block are placed on the outer ring of the filter element. Then, the turntable is rotated to drive the screw to rotate. The rotation of the screw pulls the lower sleeve to extend and retract. When the sleeve extends and retracts, it drives the external movable rod to pull the surrounding connecting blocks and the first clamping block inward, thereby clamping the filter element. Compared with clamping directly with pliers, this clamping method is not only more convenient but also will not damage the filter element.

[0018] 2. By setting the first clamping block and the adjustment mechanism, the clamping range can be adjusted according to the width of the outer ring of the filter element. By rotating the adjustment bolt, the distance between the second clamping block and the first clamping block can be adjusted to meet the width of different filter element outer rings. At the same time, the spring pieces inside the first and second clamping blocks have a certain rebound capability, which can squeeze and clamp the outer ring of the filter element, thereby improving the firmness during the disassembly of the filter element.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The filter element removal tool shown includes a bracket 1 for supporting the filter element removal tool;

[0029] Screw 4 is installed inside bracket 1 and is used to adjust the clamping range according to the size of the filter element. Turntable 5 is fixedly installed at the upper end of screw 4, and movable shaft 6 is provided at the lower end of screw 4. Sleeve 7 is provided below movable shaft 6. Fixed frame 8 is fixedly installed around sleeve 7. Movable rod 9 is movably connected inside fixed frame 8.

[0030] Connecting block 12 is arranged around the bottom of bracket 1 for clamping filter element. Connecting shaft 13 is provided inside connecting block 12. Connecting shaft 13 is movably connected to movable rod 9. Fixing block 14 is fixed below connecting block 12. First clamping block 15 is fixedly installed on one side below fixing block 14.

[0031] The adjustment mechanism 16 is installed below the fixed block 14 and is used to adjust the size of the corners of the filter element. The first clamping block 15 and the second clamping block 1602 are fitted onto the outer ring of the filter element. Then, the turntable 5 is rotated to drive the screw 4 to rotate. The rotation of the screw 4 pulls the lower sleeve 7 to extend and retract. When the sleeve 7 extends and retracts, it drives the external movable rod 9 to pull the connecting blocks 12 and the first clamping block 15 around the perimeter to move inward, thereby clamping the filter element. Compared with clamping directly with pliers, this clamping method is not only more convenient but also will not damage the filter element.

[0032] like Figure 1 and Figure 2 As shown, a sleeve 2 is fixedly installed below the bracket 1. A tightening bolt 3 is provided on one side of the sleeve 2. When the screw 4 is adjusted into place inside the sleeve 2, the screw 4 is limited and fixed by tightening the bolt 3.

[0033] like Figure 2 and Figure 3 As shown, a slide rail 10 is fixedly installed around the bottom of the bracket 1. A slider 11 is movably connected to the outside of the slide rail 10. A connecting block 12 is installed below the slider 11. The connecting block 12 slides outside the slide rail 10 below the bracket 1 using the slider 11, thereby improving the stability of the movement of the connecting block 12.

[0034] like Figure 4 and Figure 5 As shown, the adjustment mechanism 16 includes an adjustment bolt 1601, a second clamping block 1602, a spring piece 1603, a limiting block 1604, and a sliding groove 1605. The adjustment bolt 1601 passes through the inside of the first clamping block 15. One end of the adjustment bolt 1601 is movably connected to the second clamping block 1602. The limiting block 1604 is fixedly installed above the second clamping block 1602. The sliding groove 1605 is provided on the lower inner surface of the fixed block 14. By rotating the adjustment bolt 1601, the distance between the second clamping block 1602 and the first clamping block 15 is increased, thereby satisfying the width of the outer ring of different filter elements.

[0035] like Figure 5 As shown, the first clamping block 15 and the second clamping block 1602 are respectively provided with spring pieces 1603. The spring pieces 1603 inside the first clamping block 15 and the second clamping block 1602 have a certain rebound ability and can squeeze and clamp the outer ring of the filter element.

[0036] like Figure 5 As shown, the upper limiting block 1604 of the second clamping block 1602 and the sliding groove 1605 opened below the fixed block 14 limit the sliding. The limiting block 1604 and the sliding groove 1605 work together, and the second clamping block 1602 slides in the sliding groove 1605 opened below the fixed block 14 through the limiting block 1604, which improves the stability of the second clamping block 1602 when it moves.

[0037] The working principle of this utility model is as follows: First, based on the size of the filter element's outer ring, the distance between the second clamping block 1602 and the first clamping block 15 is adjusted by rotating the adjusting bolt 1601, thus accommodating different filter element outer ring widths. After adjusting the width, the first clamping block 15 and the second clamping block 1602 are placed on the filter element's outer ring. The spring plate 1603 inside the filter element is used to squeeze and clamp the outer ring. Then, the turntable 5 is rotated to drive the screw 4 to rotate. The rotation of the screw 4 pulls the lower sleeve 7 to extend and retract. When the sleeve 7 extends and retracts, it drives the outer ring... The movable rod 9 pulls the connecting blocks 12 and the first clamping block 15 around the filter element to move inward, thereby clamping the filter element. Compared with clamping directly with pliers, this clamping method is not only more convenient but also avoids damaging the filter element. Then, the operator holds the bracket 1 and pulls the clamped filter element out and places it into the frame. Next, the turntable 5 is rotated counterclockwise to drive the screw 4 to rotate, thereby releasing the filter element. Then, the operator manually presses down the filter element to disengage it from the first clamping block 15 and the second clamping block 1602. This completes the process of using the filter element disassembly tool.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
