Description

Technical Field

[0001] The utility model belongs to the technical field of dust filters, and particularly relates to an antistatic dust filter. Background Technique

[0002] A filter is an indispensable device on the conveying medium pipeline, usually installed at the inlet end of equipment such as pressure reducing valves, pressure relief valves, constant water level valves, and other equipment. Among them, a dust filter is a commonly used device for filtering impurities in dust, which can filter the dust entering the device, prevent pipeline blockage, make the dust transportation unobstructed, and ensure continuous and stable operation.

[0003] In the process of using the existing dust filter, it is necessary to regularly replace the filter element in the device to ensure the subsequent operation of the device. The existing installation method of the filter element is to set a large number of bolts on the device for fixation. The large number of bolts increases the trouble for users to disassemble later. Moreover, in the process of using the existing dust filter, it needs to be docked with other equipment. Most of the docking pipelines are fixed, which is inconvenient for adjustment, and it is easy to have trouble in docking or unsuccessful docking, reducing the application range of the device. Therefore, we need to upgrade and transform on the basis of the existing technology. Content of the Utility Model

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 - Figure 5 shown, an antistatic dust filter provided in this embodiment includes a device body 1. The device body 1 is provided with an outer housing 2. Above the outer housing 2 is provided a cover plate 6, and below the outer housing 2 is provided a sewage discharge bucket 3. Above the cover plate 6 is provided an exhaust port 7, and inside the cover plate 6 is installed a positioning plate 8. An outer filter element 9 is movably sleeved outside the positioning plate 8. Below the filter element 9 is provided a placement plate 10. Below the sewage discharge bucket 3 is provided a sewage discharge port 4, and on one side of the sewage discharge bucket 3 is provided a connecting pipe 5. Outside the cover plate 6 is fixedly provided a fixing buckle 11. Outside the outer housing 2 is fixedly provided a connecting buckle 14. A rotating buckle 15 is rotatably installed on the connecting buckle 14. Countersunk screw holes 12 and limiting grooves 13 are provided inside the fixing buckle 11 and the rotating buckle 15. Outside the sewage discharge bucket 3 is fixedly provided a U-shaped block 17. An adjusting rod 18 is sleeved outside the U-shaped block 17, and a support leg 19 is sleeved outside the adjusting rod 18.

[0027] Preferably, a lower L-groove 201 is provided on the outer wall of the outer shell 2, and an upper L-groove 71 is provided on the outer wall of the cover plate 6. The upper L-groove 71 and the lower L-groove 201 are movably connected, which can facilitate the user to assemble the outer shell 2 and the cover plate 6, providing convenience for the user and avoiding the trouble of installation and docking. Multiple groups of countersunk screw holes 12 and limiting grooves 13 are provided, and the first bolts 16 are screwed in the countersunk screw holes 12 and the limiting grooves 13. The first bolts 16 can be used to fix and limit the devices, thereby ensuring the safety of the devices during use. The opening of the countersunk screw holes 12 can accommodate the first bolts 16 to avoid the first bolts 16 occupying more space.

[0028] Preferably, multiple groups of support legs 19 are provided, and anti-skid pads 20 are provided under the multiple groups of support legs 19, and the anti-skid pads 20 are fixedly connected to the support legs 19. By providing the anti-skid pads 20, the anti-skid performance of the support legs 19 is increased, and the support legs 19 are prevented from sliding during use. Adjustment screw holes 21 are provided in the adjustment rod 18, the U-shaped block 17 and the support leg 19. Multiple groups of adjustment screw holes 21 are provided, and second bolts 22 are screwed in the adjustment screw holes 21. By providing the second bolts 22, the device can be fixed and limited. By providing the adjustment screw holes 21, the height of the device can be adjusted according to the needs of use. Anti-static coatings are provided on the outer walls of the outer shell 2, the sewage bucket 3 and the cover plate 6. By providing the anti-static coating, the anti-static ability of the device is increased, and the safety of the device during operation is ensured.

[0029] The use principle and use process of the utility model are as follows: when in use, the first bolt 16 is taken out from the countersunk screw hole 12 and the limiting groove 13 in the fixing buckle 11 and the rotating buckle 15 in turn by a tool. After taking out, the fixing buckle 11 is separated from the rotating buckle 15. At this time, the user rotates the rotating buckle 15 to the side of the connecting buckle 14 by hand, and the user removes the cover plate 6 from the outer shell 2, removes the positioning plate 8 from the filter element 9, and installs the new filter element 9 on the placement plate 10 for re-fixing. The filter element 9 of the device can be installed and fixed, which increases the practicality and convenience of the device, and is convenient for the user to disassemble the filter element 9 of the device in the later stage, avoiding installation In order to solve the problem that the filter element 9 is inconvenient to replace later, when the device connecting pipe 5 is docked with other devices and the height of the device needs to be adjusted, the user removes the second bolt 22 from the adjusting screw hole 21 in sequence. At this time, the adjusting rod 18 and the supporting leg 19 are separated, and the user pulls up the adjusting rod 18 by hand to move the adjusting rod 18 to a suitable position, and screws the second bolt 22 into the adjusting screw hole 21 again to achieve height adjustment and fixation. The height of the device can be adjusted according to the needs of use, which increases the practicability and convenience of the device and avoids the problem that the height of the device connecting pipe 5 is insufficient when docking with other devices, thereby affecting the subsequent operation of the device.
