Description

Technical Field

[0001] This utility model relates to the field of pipeline filter technology, specifically a clamp-type pipeline filter. Background Technology

[0002] During the fluid transport process, impurities may be present in the fluid. Accumulation of these impurities can easily cause pipe blockage, affecting fluid transport. Therefore, pipe filters need to be installed on fluid pipelines to filter these impurities. Pipe filters typically consist of connecting pipes, a cylinder, flanges, a filter basket, and fasteners.

[0003] Chinese utility model patent CN203379698U discloses a pipeline filter consisting of a cylindrical filter housing, a cylindrical filter screen, and a filter bottom cover. The main structure of the cylindrical filter housing is cylindrical, with internal threads on the inner wall at the bottom end. A fluid inlet pipe and a fluid outlet pipe are respectively located at the top center and the lower side of the main structure. This utility model can be connected to a fluid pipeline via a flange to filter the fluid in the pipeline. However, due to the certain length of the cylindrical filter housing and the cylindrical filter screen, a certain installation space is required when installing it, and an operating space is also required when removing the cylindrical filter screen. This makes it unsuitable for narrow installation areas and places with short pipe spacing, reducing the practicality of this pipeline filter.

[0004] Therefore, this utility model provides a clamp-type pipeline filter. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 8 This utility model provides a technical solution: a clamp-type pipeline filter, including a fixed pipe 1, a fixed box 2, and a filter box 10 installed inside the fixed box 2. The fixed box 2 is fixedly connected to the bottom end of the fixed pipe 1. A sealing gasket 9 is fixedly installed on the top inner side of the fixed box 2. A first through hole 17 and a second through hole 18 are respectively opened on both sides of the top of the filter box 10. A filter screen 11 is installed inside the second through hole 18. A handle 12 is fixedly provided at the bottom of the filter box 10. A bottom cover 6 is installed at the bottom end of the fixed box 2 through a limiting mechanism. The limiting mechanism includes a limiting rod 7 and a square frame 8. The limiting rod 7 is movably installed on both sides of the bottom end of the fixed box 2 through a mounting groove 15. The fixed box 2 and the fixed pipe 1 are integrated, which can reduce the volume of the pipeline filter and facilitate the installation of the pipeline filter in places with narrow space or short pipeline spacing, thereby improving the safety of the pipeline filter.

[0026] In this embodiment, the mounting grooves 15 are symmetrically opened on both sides of the bottom end of the fixed box 2. The limiting rod 7 is movably installed inside the mounting groove 15 through a rotating shaft set at its top end. The limiting rod 7 is L-shaped. A support strip 13 is fixedly installed on the outer wall of the limiting rod 7. The bottom end of the limiting rod 7 is snapped into the bottom sides of the bottom cover 6. The bottom ends of the bottom cover 6 are provided with grooves corresponding to the positions of the limiting rod 7. The limiting rod 7 is installed inside the grooves. The bottom cover 6 is abutted against the bottom of the filter box 10. The limiting rod 7 can be rotated and stored through the mounting grooves 15. The bottom end of the limiting rod 7 is snapped into the grooves and the bottom of the bottom cover 6, which facilitates quick installation of the bottom cover 6 and quick disassembly of the bottom cover 6 and the filter box 10, thereby facilitating the cleaning of impurities inside the filter box 10.

[0027] In this embodiment, the square frame 8 is slidably installed on the outside of the fixed box 2. The square frame 8 is positioned above the support bar 13. A magnet 14 is fixedly installed inside the bottom end of the square frame 8. Both the support bar 13 and the limiting rod 7 are made of iron. The square frame 8 is fitted to the top of the support bar 13. The square frame 8 can be fixed to the top of the support bar 13 under the magnetic attraction of the magnet 14, which facilitates the limiting of the limiting rod 7, improves the stability of the limiting rod 7, and facilitates the fixing of the bottom cover 6.

[0028] In this embodiment, a sealing groove 16 is provided on the top outer side of the first through hole 17 and the second through hole 18 corresponding to the top of the filter box 10. A protrusion is provided on the bottom end of the sealing gasket 9 corresponding to the position of the sealing groove 16. The protrusion is installed inside the sealing groove 16. An inner hole is provided inside the sealing gasket 9. An inlet 3 and an outlet 4 are respectively provided at both ends of the fixed tube 1. An annular groove 5 is provided on the outer side of both the inlet 3 and the outlet 4. The inlet 3 and the outlet 4 are interconnected with the first through hole 17 and the second through hole 18 through the inner hole respectively. The sealing gasket 9, the protrusion and the sealing groove 16 facilitate the sealing and communication between the fixed tube 1 and the filter box 10. The sealing gasket 9 can also fix the filter screen 11, which facilitates the filtration of fluid through the filter box 10.

[0029] When using this clamp-on pipe filter, slide the square frame 8 upward on the outside of the fixed box 2, and rotate the limiting rod 7 to both sides via the rotating shaft to install the filter screen 11 inside the second through hole 18. Move the filter box 10 through the handle 12 and insert the filter box 10 from the bottom of the fixed box 2. The top of the filter box 10 abuts against the bottom of the sealing gasket 9 through the protrusion and sealing groove 16, so that the inlet 3 communicates with the first through hole 17 through the inner hole, and the outlet 4 communicates with the second through hole 18 through the inner hole. The bottom cover 6 is inserted and installed in the fixed box 2. The bottom of the filter box 10 is abutted against the bottom of the filter box 10. The limiting rod 7 is rotated in the opposite direction and enters the interior of the mounting groove 15 and the recess. Its bottom end is engaged with the bottom sides of the bottom cover 6. The square frame 8 is slid down and moves to the outside of the top of the limiting rod 7 and is in contact with the top of the support bar 13. At the same time, the magnetic attraction between the magnet 14 and the support bar 13 facilitates the fixation of the square frame 8. The two ends of the fixing pipe 1, the inlet 3 and the outlet 4, are respectively connected to the two pipe flanges and abut against each other. The interior of the annular groove 5 is installed between the flange and the flange. Install sealing rings, install double-ended bolts between the two pipe flanges, and screw washers and nuts to both ends of the double-ended bolts. The fixed pipe 1 is then pressed and fixed by the two pipe flanges. Adjust the orientation of the fixed box 2 according to the available space to facilitate the installation of the pipeline filter. The fixed pipe 1 and fixed box 2 of this pipeline filter are integrated, resulting in a compact structure and small footprint. The clamp-on installation method facilitates installation in confined spaces or areas with short pipe spacing, improving the practicality of the pipeline filter. Fluid enters the filter box 10 through the inlet 3, inner hole, and first through hole 17, and is discharged through the inner hole and outlet 4 after being filtered by the filter screen 11. This facilitates the filtration of the fluid in the pipeline. Impurities are trapped in the filter box 10 and collected. Slide the square frame 8 on the fixed box 2 to separate the square frame 8 from the limiting rod 7, and rotate the limiting rod 7 to both sides to facilitate the disassembly of the bottom cover 6 and the filter box 10, allowing for easy cleaning of impurities inside the filter box 10 and ensuring the smooth flow of fluid through the pipeline.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
