Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration devices, in particular to an ultrafiltration device which is convenient for replacing filter membranes. Background Art

[0002] Ultrafiltration is a filtering technology used to separate large molecules from small molecules in a solution. It is usually used in water treatment, biopharmaceuticals, and food processing. It separates water and solutes through a semipermeable membrane, allowing water and smaller solutes to pass through, while larger solutes are retained on one side of the membrane. This technology is very effective in removing suspended matter, bacteria, viruses, and organic matter. After using the ultrafiltration device for a period of time, it is necessary to open the ultrafiltration device and replace the filter membrane inside it to ensure the filtration efficiency of the ultrafiltration device.

[0003] The Chinese patent "A water purification device for easy replacement of ultrafiltration membrane filter element" authorization announcement number "CN214571311U" uses a screw rod, a handle and a clamping ring to release the clamping of the core tube, and then remove the water pipe between the core tubes, finally facilitating the disassembly of the core tube for replacement, thereby solving the problem of inconvenient and stable replacement of the filter element.

[0004] In the above-mentioned replacement of the filter membrane, it is necessary to release the clamping of the core tube, then release the fixing state of the core tube and the water pipe, and then open the core tube to replace the filter membrane inside it. This method makes the replacement of the filter membrane too inconvenient.

[0005] Therefore, an ultrafiltration device which is convenient for replacing filter membrane is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5As shown, an ultrafiltration device for facilitating replacement of filter membranes comprises: a mounting frame 1, two connecting tubes 2 are fixedly connected to the inner side of the mounting frame 1, and core tubes 3 arranged in equal rows are arranged at opposite ends of the two connecting tubes 2; a disassembly and assembly mechanism 4 is arranged on the inner side of the mounting frame 1; wherein the disassembly and assembly mechanism 4 comprises magnetic grooves 41 arranged in equal rows at the front and rear ends of the mounting frame 1, and magnetic blocks 42 are fixedly connected to the upper and lower ends of the surface of the core tube 3, and the surface of the magnetic block 42 is clamped to the inner wall of the magnetic groove 41 and attracts each other with opposite poles, and the inner wall of the mounting frame 1 is slidably connected to the magnetic groove 41. There are anti-loosening blocks 43 distributed in equal columns, the surface of the anti-loosening blocks 43 is clamped on the inner wall of the magnetic block 42, the rear end of the anti-loosening block 43 is fixedly connected to the connecting frame 44, the inner wall of the mounting frame 1 is rotatably connected to a toggle rod 49, one end of the toggle rod 49 is fixedly connected to a push plate 48, the upper and lower ends of the surface of the core tube 3 are slidably connected to sealing covers 46, the surface of the sealing cover 46 is clamped on the inner wall of the connecting tube 2, the front end of the anti-loosening block 43 is fixedly connected to a limiting frame 45, the surface of the sealing cover 46 is fixedly connected to a handle 415, and the inner side of the limiting frame 45 is fixedly connected to a cushion 47.

[0026] It should be noted that the connecting tube 2, the core tube 3, the magnetic block 42 and the magnetic slot 41 in the above description are all relatively mature devices in the existing technology, and the specific models can be selected according to actual needs.

[0027] When the ultrafiltration device filters water for a period of time and the filter membrane in the core tube 3 needs to be replaced, the positioning of the toggle rod 49 is released and it is rotated. The rotation of the toggle rod 49 drives the push plate 48 to rotate, so that the highest point of the push plate 48 is separated from the connecting frame 44, and the two connecting frames 44 are pulled close to each other, so that the anti-loosening block 43 is away from the magnetic block 42, and the limit frame 45 is away from the sealing cover 46. At this time, the two sealing covers 46 are pulled away from their respective connecting tubes 2 by the handle 415, and the handle 415 is pulled in the direction away from the connecting tube 2 to separate the core tube 3 from the connecting tube 2 and the mounting frame 1, so that the filter membrane in the core tube 3 can be easily replaced. After replacing the filter membrane in the core tube 3 at the front end of the rear mounting frame 1, the filter membrane in the core tube 3 at the rear end of the mounting frame 1 is replaced, thereby avoiding the simultaneous rotation of the two push plates 48 and ensuring the activity space of the push plates 48.

[0028] like Figure 4 As shown, the inner wall of the mounting frame 1 is slidably connected to a limit rod 410, the surface of the limit rod 410 is clamped on the inner wall of the toggle rod 49, one end of the limit rod 410 is fixedly connected to a spring 411, the other end of the spring 411 is fixedly connected to the inner wall of the mounting frame 1, the upper end of the surface of the limit rod 410 is fixedly connected to a movable frame 413, the surface of the movable frame 413 is slidably connected to the inner wall of the mounting frame 1, the upper end of the surface of the toggle rod 49 is fixedly connected to an indirect rod 412, and a blocking block 414 is fixedly connected to one side of the mounting frame 1.

[0029] After the filter membrane in the core tube 3 is replaced, the core tube 3 is placed between the two connecting tubes 2 through the handle 415, so that the magnetic block 42 is clamped in the magnetic groove 41, and the other three core tubes 3 are placed in turn, and the toggle rod 49 is rotated. The toggle rod 49 rotates to drive the push plate 48 to rotate. During the rotation of the push plate 48, the two connecting frames 44 are pushed away from each other, and the connecting frame 44 moves to drive the anti-loosening block 43 to be clamped in the magnetic block 42. The anti-loosening block 43 moves to drive the limiting frame 45 to move, and the limiting frame 45 moves to push the sealing cover 46 to be clamped in the connecting tube 2, so that the indirect rod 412 contacts the movable frame 413, and the highest point of the push plate 48 contacts the connecting frame 44. At this time, the elastic force of the spring 411 pushes the limiting rod 410 to move and connect the toggle rod 49, and the limiting rod 410 moves to drive the movable frame 413 to move and contact the indirect rod 412, so that the core tube 3 is respectively fixed on the mounting frame 1 and the connecting tube 2.

[0030] When the utility model is in use, the movable frame 413 is pulled to make the movable frame 413 away from the indirect rod 412, the limiting rod 410 away from the toggle rod 49, the toggle rod 49 rotates to drive the push plate 48 to rotate, and the interference with the connecting frame 44 is released, and the two connecting frames 44 are pulled closer to each other, so that the anti-loosening block 43 is away from the magnetic block 42, and the limiting frame 45 is away from the sealing cover 46. At this time, the two sealing covers 46 are pulled away from their respective connecting pipes 2 through the handle 415, and the handle 415 is pulled to move in the direction away from the connecting pipe 2, so that the core tube 3 is separated from the connecting pipe 2 and the mounting frame 1, and the filter membrane in the core tube 3 can be conveniently replaced.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
