Description

Technical Field

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

[0002] Because the filters inside the pipeline need to be cleaned or replaced after prolonged use, a removable high-efficiency pipeline filter is required.

[0003] Chinese patent CN220899661U discloses a detachable high-efficiency pipeline filter, including a cylindrical body. The cylindrical body has filter plate tracks inside, and filter plates are arranged between the tracks. Connecting blocks are provided on the outer surfaces of the filter plates, with one end of each block extending into the interior of the filter plate tracks. A top cover is provided on the top of the cylindrical body. This patent significantly improves the strength of the equipment by changing the filter element manufacturing material and the filter element structure, especially overcoming the problem of filter element deformation. The pluggable track structure facilitates the fixing of filter plates and easy disassembly, allowing for rapid manufacturing and installation under complex conditions. Furthermore, this modification allows for the design of different filter specifications for different production conditions based on flow rate, solving the problem of filter elements being frequently flattened and damaged. It also addresses the difficulties in disassembling and cleaning filter elements, inconvenient maintenance, and short service life, significantly improving process requirements and increasing filter efficiency.

[0004] In the above technical solution, the top cover and the cylinder are fixed by a flange. When the filter plate needs to be disassembled for cleaning or replacement, the bolts on the flange need to be removed one by one. After cleaning or replacing the filter plate, the bolts need to be installed on the flange one by one. The operation process is cumbersome, resulting in low practicality of the device.

[0005] Based on this, the present invention proposes a detachable high-efficiency pipeline filter. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a detachable high-efficiency pipeline filter. By pressing the knob, the limiting rod can be moved from the slot to the groove. Then, by rotating the knob, the limiting rod is rotated to the bottom of the through groove. At this point, the top cover can be pulled by the handle to separate it from the fixed shell, enabling quick disassembly of the filter plate and improving the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is: a detachable high-efficiency pipeline filter, including a cylinder, a filter plate provided inside the cylinder, a fixed shell fixedly connected to the cylinder by a flange, and further comprising;

[0008] The groove is formed inside the fixed shell. The fixed shell has four through slots that are connected to the groove. A top cover is rotatably connected to the filter plate. A limiting slot is formed inside the top cover. A knob is provided on the top cover. A limiting rod is fixedly connected to the knob. The limiting rod is adapted to the through slot and is located inside the limiting slot.

[0009] Preferably, the cylinder is provided with a washing water inlet, a drain outlet and a washing water outlet, and each of the washing water inlet, drain outlet and washing water outlet is provided with a flange.

[0010] Preferably, four limiting strips are fixedly connected to the filter plate, and the four limiting strips are slidably connected to the cylinder body.

[0011] Preferably, the fixed shell has four slots, which are connected to the groove, and the limiting rod is adapted to the slots.

[0012] Preferably, a rotating shaft is rotatably connected to the knob, and a spring is fixedly connected to the rotating shaft, with the spring fixedly connected inside the top cover.

[0013] Preferably, two handles are fixedly connected to the fixed shell.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] In this invention, when the filter plate needs to be cleaned or replaced, pressing the knob moves the limiting rod downward, causing it to move from the slot into the groove. Then, rotating the knob causes the limiting rod to rotate, moving it within the limiting groove of the top cover. When the limiting rod is directly below the through groove, releasing the knob and pulling the handle causes the top cover to move upward. The limiting rod then moves out of the fixed shell along the through groove, separating the top cover from the fixed shell. The filter plate moves out of the cylinder along with the top cover, allowing the filter plate to be quickly disassembled and removed for cleaning or replacement, thus improving the practicality of the device.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides a detachable high-efficiency pipeline filter through improvements. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a detachable high-efficiency pipeline filter includes a cylinder 1, a filter plate 10 inside the cylinder 1, a fixed shell 6 fixedly connected to the cylinder 1 by a flange 5, and also includes;

[0026] The groove 7 is formed inside the fixed shell 6. The fixed shell 6 has four through slots 8, which are arranged in a circular array with the center of the fixed shell 6 as the center. The four through slots 8 are connected to the groove 7. The filter plate 10 is rotatably connected to the top cover 12. The top cover 12 has a limiting slot 14. The top cover 12 has a knob 15 with a "T" shaped cross section. A limiting rod 18 with a "+" shaped cross section is fixedly connected to the knob 15. The limiting rod 18 is adapted to the through slot 8 and is located in the limiting slot 14. When the filter plate 10 is placed inside the cylinder 1, the limiting rod 18 is embedded in the slot 9. When the filter plate 10 needs to be removed from the cylinder 1, the limiting rod 18 is embedded in the through slot 8. This device allows the filter plate 10 to be quickly disassembled, making it easy to clean or replace, thus improving the practicality of the device.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, the cylinder 1 is provided with a washing water inlet 2, a drain outlet 3 and a washing water outlet 4. Each of the washing water inlet 2, drain outlet 3 and washing water outlet 4 is provided with a flange 5, which is connected to the external interface through the flange 5.

[0028] Furthermore, such as Figure 4As shown, four limiting strips 11 are fixedly connected to the filter plate 10. The four limiting strips 11 are slidably connected inside the cylinder 1. The limiting strips 11 are arranged in a circular array with the center of the filter plate 10 as the center. The limiting strips 11 limit the filter plate 10 and prevent the filter plate 10 from rotating inside the cylinder 1.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, four slots 9 are provided inside the fixed shell 6. The slots 9 are arranged in a circular array with the center of the fixed shell 6 as the center. The slots 9 are staggered with the through slots 8. The four slots 9 are connected to the grooves 7. The limiting rod 18 is adapted to the slots 9.

[0030] Furthermore, such as Figure 2 As shown, a rotating shaft 16 is rotatably connected to the knob 15, and a spring 17 is fixedly connected to the rotating shaft 16. The spring 17 is fixedly connected inside the top cover 12. The spring 17 ensures that the limiting rod 18 is always embedded in the slot 9 without external force, thus preventing the top cover 12 from shaking.

[0031] Furthermore, such as Figures 1-4 As shown, two handles 13 are fixedly connected to the fixed shell 6. The two handles 13 are symmetrical about the knob 15. When the limiting rod 18 moves to the bottom of the through groove 8, the top cover 12 and the filter plate 10 can be pulled out from the cylinder 1 through the handles 13.

[0032] The specific working method is as follows: When it is necessary to clean or replace the filter plate 10, press the knob 15 to move the limiting rod 18 down, so that the limiting rod 18 moves from the slot 9 into the groove 7. Then rotate the knob 15, and the limiting rod 18 rotates accordingly, so that the limiting rod 18 moves in the limiting groove 14 of the top cover 12. When the limiting rod 18 rotates to the bottom of the through groove 8, release the knob 15 and pull the handle 13, so that the top cover 12 moves up and the limiting rod 18 moves out of the fixing shell 6 along the through groove 8, so that the top cover 12 is separated from the fixing shell 6. Since the filter plate 10 is rotatably connected to the top cover 12, the filter plate 10 moves out of the cylinder 1 along with the top cover 12, so that the filter plate 10 can be quickly disassembled and taken out, which is convenient for cleaning or replacement, and improves the practicality of the device.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
