Description

Technical Field

[0001] This utility model relates to the field of metal sintered mesh filter technology, and in particular to a multilayer metal sintered mesh filter. Background Technology

[0002] Multi-layer sintered metal mesh filter element is a high-performance filter element made of multiple layers of metal wire mesh through a vacuum high-temperature sintering process. It features high precision, high strength, high temperature resistance, corrosion resistance, and easy cleaning, and is widely used in solid-liquid and gas-solid separation scenarios in petrochemical, pharmaceutical, food and beverage, energy and environmental protection fields.

[0003] In the manufacturing process of multi-layer sintered metal mesh filter elements, the surface metal mesh is often connected to the frame by welding. However, after long-term use, the metal mesh is the most vulnerable part of the multi-layer sintered metal mesh filter element, and it is prone to breakage. Since the metal mesh is welded to the frame, it is not replaced, and the entire filter element often needs to be replaced, resulting in a waste of resources.

[0004] Therefore, a multi-layer metal sintered mesh filter element is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer metal sintered mesh filter element to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer metal sintered mesh filter element, comprising two frames, a connecting plate fixedly connected between the two frames, and a metal filter screen disposed between the frames; a fixing component is provided on the metal filter screen, the fixing component being used for quick replacement of the metal filter screen on the frame, the fixing component including fixing plates fixedly connected to the two end faces of the metal filter screen, and a limiting plate for fixing and pressing the fixing plate on one side of the fixing plate.

[0007] Preferably, a limiting post is fixedly connected to the connecting plate, a support cover is provided between the frames, the support cover is provided with a plurality of filter holes, the limiting post penetrates through the support cover, and a mounting platform is provided on the frame, with the support cover located on the mounting platform.

[0008] Preferably, the fixing plate has a limiting hole, the fixing plate and the metal filter screen surround the outer ring of the support cover, and the limiting post passes through the limiting hole.

[0009] Preferably, each of the two frames is fixedly connected to a mounting bracket, and a guide rod is fixedly connected to the lower mounting bracket, the guide rod being slidably connected to the limiting plate.

[0010] Preferably, a threaded rod is rotatably connected to the mounting bracket at the top, and the threaded rod is connected to the threaded rod of the limiting plate.

[0011] Preferably, the limiting plate is provided with a through hole for the limiting post to pass through, and a rotating plate is fixedly connected to the end of the threaded rod.

[0012] Preferably, the rotating plate is provided with an anti-slip rubber pad.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a fixing assembly that, when the rotating plate drives the threaded rod to rotate, the limiting plate disengages from the fixing plate with the assistance of the guide rod. This facilitates the removal of the fixing plate and the metal filter screen from the outside of the support cover, thus completing the disassembly of the metal filter screen. For replacement and reinstallation, the fixing plate and metal filter screen are wrapped around the support cover, the fixing plate is fastened to the limiting post, and the threaded rod is rotated again to allow the limiting plate to move closer to and adhere to the fixing plate on the guide rod, thereby completing the limiting and fixing of the fixing plate and the installation of the metal filter screen. The entire device makes replacing the metal filter screen quicker and simpler, avoiding the need to discard the entire sintered metal mesh filter element due to damage, thus reducing resource waste.

[0024] like Figures 1 to 5 As shown in the figure, a specific embodiment of this utility model provides a multi-layer metal sintered mesh filter element, including two frames 1, a connecting plate 2 fixedly connected between the two frames 1, and a metal filter 3 disposed between the frames 1; the metal filter 3 is provided with a fixing component, which is used for quick replacement of the metal filter 3 on the frame 1. After long-term use of the metal sintered mesh filter element, if the metal filter 3 on its surface is damaged, the metal filter 3 can be quickly and conveniently replaced by the fixing component, thereby ensuring the normal use of the metal sintered mesh filter element and avoiding the situation where the entire metal sintered mesh filter element needs to be discarded due to damage to the metal filter 3, thus reducing resource waste. The fixing component includes a fixing plate 4 fixedly connected to the two end faces of the metal filter 3, and a limiting plate 5 for fixing and pressing the fixing plate 4 is provided on one side of the fixing plate 4.

[0025] like Figures 1 to 5As shown, specifically, a limiting post 6 is fixedly connected to the connecting plate 2, a support cover 7 is provided between the frames 1, the support cover 7 has several filter holes, the limiting post 6 penetrates the support cover 7, a mounting platform 8 is provided on the frame 1, and the support cover 7 is located on the mounting platform 8. The limiting post 6 is used to keep the support cover 7 in a limited position. Mounting brackets 10 are fixedly connected to both frames 1, and a guide rod 11 is fixedly connected to the lower mounting bracket 10. The guide rod 11 is slidably connected to the limiting plate 5, and a threaded rod 12 is rotatably connected to the upper mounting bracket 10. The threaded rod 12 is threadedly connected to the limiting plate 5. The limiting plate 5 has a... A rotating plate 14 is fixedly connected to the end of the threaded rod 12 through the through hole 13 of the limiting post 6. The rotating plate 14 is provided with an anti-slip rubber pad. When disassembling the metal filter screen 3, rotating the rotating plate 14 drives the threaded rod 12 to rotate, thereby allowing the limiting plate 5 to gradually detach from the fixing plate 4 with the cooperation of the guide rod 11, thus eliminating the squeezing of the fixing plate 4. At the same time, the limiting plate 5 detaches from the limiting post 6. After the limiting plate 5 no longer limits and fixes the fixing plate 4, the two fixing plates 4 can be removed from the limiting post 6. Since the fixing plate 4 and the metal filter screen 3 are designed as a whole, they can be replaced.

[0026] like Figures 1 to 5 As shown, a limiting hole 9 is provided on the fixing plate 4. The fixing plate 4 and the metal filter screen 3 are arranged around the outer ring of the support cover 7, and the limiting post 6 passes through the limiting hole 9. When installing after replacement, the fixing plate 4 and the metal filter screen 3 are wrapped around the outer perimeter of the support cover 7 as a whole, and the two fixing plates 4 are fastened to the limiting post 6 through the limiting hole 9, thereby installing the fixing plate 4 and the metal filter screen 3 on the support cover 7. The metal filter screen 3 and the support cover 7 achieve the effect of using a metal sintered mesh filter element. The rotating plate 14 is provided with an anti-slip rubber pad. The anti-slip rubber pad increases friction, thereby facilitating the rotation of the rotating plate 14. Then, the rotating plate 14 is rotated again to make the threaded rod 12 rotate, so that the limiting plate 5 moves along the guide rod 11 and gradually approaches the fixing plate 4 and squeezes and fixes it. Thus, the limiting plate 5 can complete the limiting and fixing of the fixing plate 4, that is, complete the installation and fixing of the metal filter screen 3.
