Description

Technical Field

[0001] This utility model relates to the field of tubular filter technology, specifically a tubular filter with a removable and replaceable filter element. Background Technology

[0002] Tubular filters are mainly used to remove small amounts of particulate matter from liquids. They can protect compressors, pumps, instruments, and other equipment, ensuring their normal operation and extending their service life. When liquid flows into the filter cartridge, it blocks impurities in the liquid, and the treated, clean liquid is discharged from the filter outlet. Currently, tubular filters are mostly fixed to the flange using bolts and nuts. Therefore, when replacing the filter element, the bolts and nuts need to be removed, the flange opened, and the filter element removed for replacement, which is inconvenient. Therefore, we propose a tubular filter with a removable and replaceable filter element. Utility Model Content

[0003] The purpose of this invention is to provide a tubular filter with a removable and replaceable filter element to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tubular filter with a detachable and replaceable filter element, comprising a tubular filter, wherein a filter element is provided inside the tubular filter, and a first sealing plate is provided on both the left and right side walls of the tubular filter, and four sets of insertion holes are provided on the opposite side walls of the two sets of first sealing plates, and flanges are provided on both the left and right sides of the tubular filter, and a second sealing plate is provided on the opposite side walls of the two sets of flanges, and four sets of fixing components are hinged to the outer side walls of the two sets of second sealing plates.

[0005] Furthermore, the fixing assembly includes a connecting plate hinged to the outer wall of the second sealing plate, a sliding plate slidably connected inside the connecting plate, a plug matching the insertion hole on the left side wall of the sliding plate, and a screw on the right side wall of the sliding plate, one end of which passes through the inner right side wall of the connecting plate and is connected to an externally provided adjustment knob.

[0006] Furthermore, the connecting plate is U-shaped.

[0007] Furthermore, a sliding rod is movably provided through the right side wall of the sliding plate, and the two ends of the sliding rod are respectively connected to the left and right side walls inside the connecting plate.

[0008] Furthermore, a guide groove is provided at the top of the connecting plate, and a guide block matching the guide groove is provided at the top of the sliding plate.

[0009] Furthermore, each of the two sets of first sealing plates has three sets of positioning holes on the opposite sidewalls, and each of the two sets of second sealing plates has positioning blocks on the opposite sidewalls that match the positioning holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: with the cooperation of positioning holes, positioning blocks, insertion holes and fixing components, the flange can be quickly disassembled, thereby facilitating the replacement of the filter element.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Example 1:

[0016] Please see Figure 1-2 This utility model provides a technical solution: a tubular filter with a detachable and replaceable filter element, including a tubular filter 1, a filter element 5 inside the tubular filter 1, a first sealing plate 3 on both the left and right side walls of the tubular filter 1, four sets of insertion holes 9 on the opposite side walls of the two sets of first sealing plates 3, flanges 2 on both the left and right sides of the tubular filter 1, a second sealing plate 6 on the opposite side walls of the two sets of flanges 2, three sets of positioning holes 4 on the opposite side walls of the two sets of first sealing plates 3, and positioning blocks 7 on the opposite side walls of the two sets of second sealing plates 6 that match the positioning holes 4. Under the action of the positioning holes 4 and the positioning blocks 7, the first sealing plate 3 and the second sealing plate 7 can be tightly fitted together, and four sets of fixing components 8 are hinged to the outer side walls of the two sets of second sealing plates 6.

[0017] Please see Figure 2The fixing component 8 includes a connecting plate 80 hinged to the outer wall of the second sealing plate 6. The connecting plate 80 is U-shaped. A sliding plate 82 is slidably connected inside the connecting plate 80. A sliding rod 81 is movably inserted through the right side wall of the sliding plate 82. The two ends of the sliding rod 81 are respectively connected to the left and right side walls inside the connecting plate 80. Under the action of the sliding rod 81, the sliding plate 82 moves more stably. A guide groove is opened at the top inside the connecting plate 80. A guide block matching the guide groove is provided at the top of the sliding plate 82. Under the action of the guide groove and the guide block, the sliding plate 82 moves more stably inside the connecting plate 80. A plug block 85 matching the plug hole 9 is provided on the left side wall of the sliding plate 82. A screw 83 is provided on the right side wall of the sliding plate 82. One end of the screw 83 passes through the right side wall inside the connecting plate 80 and is connected to an externally provided adjustment knob 84.
