Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and more specifically to a detachable filter assembly for the generation of cross-linked sodium hyaluronate. Background Technology

[0002] Cross-linked sodium hyaluronate is a polymer material widely used in medical, cosmetic and other fields. Its preparation process often involves filtration and purification steps to remove impurities and improve product purity. The filtration process usually adopts a multi-stage filtration system, which separates the target substance from impurities step by step through filter media with different pore sizes or materials to ensure the uniformity and stability of the product.

[0003] However, existing cross-linked sodium hyaluronate filtration devices often require production to be suspended and the filtration system to be turned on when replacing the filter components, which increases the risk of material leakage and cross-contamination. Therefore, a detachable filter component for the production of cross-linked sodium hyaluronate is needed to address the shortcomings of the existing system. Utility Model Content

[0004] One of the technical problems this application aims to solve is to overcome the shortcomings of existing cross-linked sodium hyaluronate filtration devices, which often require production to be suspended and the filtration system to be turned on when replacing filter components, thus increasing the risk of material leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable filter assembly for the generation of cross-linked sodium hyaluronate includes a filter box, with receiving boxes fixedly connected to both sides of the filter box. Several receiving frames are fixedly connected inside the filter box, and filter plates are movably connected inside each receiving frame. A separating and sealing assembly is provided inside the filter box and the receiving boxes to disconnect the communication between the receiving frames. The separating and sealing assembly includes several sealing cloths, and the receiving frames are respectively located between adjacent sealing cloths. A set of symmetrical limiting components is fixedly connected inside the filter box and the receiving boxes to fix the filter plates inside the filter box.

[0007] In some embodiments, the separating sealing assembly includes a rotating rod, a synchronous pulley, and a synchronous belt. A set of symmetrical rotating rods are provided on both sides of the receiving frame. Synchronous pulleys are fixedly connected to both ends of the rotating rods. Synchronous belts are sleeved on the outer sides of the two synchronous pulleys at the same horizontal height, and the synchronous pulleys and synchronous belts constitute a belt drive structure. The opposite sides of the synchronous belts at the same horizontal height are fixedly connected to two sealing cloths, and the sealing cloths are made of flexible material.

[0008] In some embodiments, the separating sealing assembly further includes sprockets and chain belts, with sprockets fixedly connected to the same end of each rotating rod, and chain belts sleeved on the outer sides of adjacent sprockets, and the sprockets and chain belts forming a chain drive structure.

[0009] In some embodiments, the synchronous pulley is movably connected to the interior of the housing via a rotating rod, the synchronous belt is movably connected to the interior of the filter box and the housing, the sprocket and the chain belt are both located on the outside of the housing, a servo motor is fixedly connected to the outside of the housing, and the output end of the servo motor is fixedly connected to one end of the rotating rod.

[0010] In some embodiments, the limiting component includes a partition and a limiting bolt. One end of the partition has several limiting grooves, and the inner side of the limiting grooves has screw holes. The partition is movably connected to the limiting bolts through the screw holes. Each end of the filter plate is fixedly connected to an installation strip, and the end of the installation strip is adapted to the limiting groove.

[0011] In some embodiments, each end of the mounting strip has a limiting hole, and a limiting bolt moves through the limiting hole, so that the mounting strip is adapted to one side of the filter box.

[0012] In some embodiments, the partition is fixedly connected to the connection between the filter box and the housing box, the timing belt moves through the partition, and the sealing cloth moves through the partition.

[0013] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a detachable filter assembly for the generation of cross-linked sodium hyaluronate, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the separation and sealing components, initially positions the sealing cloth at the bend of the synchronous belt, so that the sealing cloth does not block the receiving frame. When the sealing cloth moves to the top and bottom of the receiving frame, the four sealing cloths simultaneously block the three receiving frames, thereby preventing material flow between the filter plates. At this time, it is convenient to replace the filter plates. During the replacement process, no material will flow out of the filter box, ensuring the safety of filter plate replacement.

[0015] 2. This utility model uses a limiting component to allow the filter plate and the receiving frame to move together. By pulling out the mounting strip, the filter plate can be pulled out from the inside of the receiving frame, allowing for the removal and replacement of the filter plate. Then, the new filter plate is inserted into the receiving frame until the end of the mounting strip is engaged in the limiting groove. Subsequently, the limiting bolt is passed through the limiting hole and rotated to fix the limiting bolt to the partition plate, thus completing the replacement of the filter plate and ensuring a stable connection between the filter plate and the filter box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, this utility model provides a technical solution: a detachable filter assembly for the generation of cross-linked sodium hyaluronate, including a filter box 1. The filter box 1 shown in the figure is a partial structural schematic diagram of cross-linked sodium hyaluronate, mainly showing the details of the filtration part. Both sides of the filter box 1 are fixedly connected to a receiving box 2. Several receiving frames 3 are fixedly connected inside the filter box 1, and filter plates 4 are movably connected inside each receiving frame 3. In this embodiment, there are three filter plates 4, and the filter plates 4 are arranged longitudinally. Each filter plate 4 is filled with different filter components, thereby filtering the cross-linked sodium hyaluronate layer by layer. The filter box 1 and the receiving box 2 are provided with a separating sealing assembly 5, which is used to disconnect the communication between the receiving frames 3. The separating sealing assembly 5 includes several sealing cloths 6, and the receiving frames 3 are respectively located between adjacent sealing cloths 6. A set of symmetrical limiting assemblies 7 are fixedly connected inside the filter box 1 and the receiving box 2, which is used to fix the filter plates 4 inside the filter box 1.

[0025] like Figure 1 and Figure 4 As shown, the separating sealing assembly 5 includes a rotating rod 501, a synchronous pulley 502, and a synchronous belt 503. A set of symmetrical rotating rods 501 are provided on both sides of the receiving frame 3. Synchronous pulleys 502 are fixedly connected to both ends of the rotating rods 501. Synchronous belts 503 are sleeved on the outer sides of two synchronous pulleys 502 at the same horizontal height, and the synchronous pulleys 502 and synchronous belts 503 constitute a belt drive structure. The opposite sides of the synchronous belts 503 at the same horizontal height are fixedly connected to two sealing cloths 6, and the sealing cloths 6 are made of flexible material. The separating sealing assembly 5 also includes a sprocket 504 and a chain belt 505. A sprocket 504 is fixedly connected to the same end of each rotating rod 501. Adjacent... A chain belt 505 is fitted on the outer side of each sprocket 504, and the sprocket 504 and the chain belt 505 constitute a chain drive structure. The synchronous pulley 502 is movably connected to the inside of the housing 2 through the rotating rod 501. The synchronous belt 503 is movably connected to the inside of the filter box 1 and the housing 2. The sprocket 504 and the chain belt 505 are both located on the outside of the housing 2. A servo motor 11 is fixedly connected to the outside of the housing 2, and the output end of the servo motor 11 is fixedly connected to one end of the rotating rod 501. In this embodiment, there are four rotating rods 501 and four sealing cloths 6, which can completely cover the upper and lower sides of the three housing frames 3.

[0026] The servo motor 11 is started, which drives the rotating rod 501 to rotate, causing the synchronous pulley 502 to rotate simultaneously. This controls the synchronous rotation of several synchronous belts 503 and the synchronous rotation of the sealing cloth 6. Since the sealing cloth 6 is made of flexible material, in the initial state, the sealing cloth 6 is located at the bend of the synchronous belt 503, so the sealing cloth 6 will not block the receiving frame 3. When the sealing cloth 6 moves directly above and below the receiving frame 3, the four sealing cloths 6 simultaneously block the three receiving frames 3, thereby preventing the flow of material between the filter plates 4. At this time, it is convenient to replace the filter plates 4. During the replacement process, the material inside the filter box 1 will not flow out, ensuring the safety of replacing the filter plates 4.

[0027] like Figure 1 and Figure 3 As shown, the limiting assembly 7 includes a partition 701 and a limiting bolt 702. One end of the partition 701 has several limiting grooves 8, and the inner side of the limiting grooves 8 has screw holes. The partition 701 is movably connected to the limiting bolt 702 through the screw holes. The ends of the filter plates 4 are all fixedly connected to the mounting strips 9. The ends of the mounting strips 9 are adapted to the limiting grooves 8. The ends of the mounting strips 9 are all opened with limiting holes 10, and the limiting bolts 702 movably pass through the limiting holes 10. The mounting strips 9 are adapted to one side of the filter box 1. The partition 701 is fixedly connected to the connection between the filter box 1 and the receiving box 2. The synchronous belt 503 movably passes through the partition 701, and the sealing cloth 6 movably passes through the partition 701.

[0028] The filter plate 4 is movably fitted with the receiving frame 3. By pulling out the mounting strip 9, the filter plate 4 can be pulled out from the inside of the receiving frame 3. At this time, the filter plate 4 can be disassembled and replaced. Then, the new filter plate 4 is inserted into the receiving frame 3 until the end of the mounting strip 9 is engaged in the limiting groove 8. Then, the limiting bolt 702 is inserted through the limiting hole 10 and the limiting bolt 702 is rotated to fix the limiting bolt 702 to the partition plate 701. This completes the replacement of the filter plate 4 and allows the filter plate 4 to be stably connected to the filter box 1.

[0029] Working principle: In use, firstly, when the filter plate 4 needs to be replaced, the servo motor 11 is started, which drives the rotating rod 501 to rotate, causing the synchronous wheel 502 to rotate simultaneously, thereby controlling the synchronous rotation of several synchronous belts 503 and controlling the synchronous rotation of the sealing cloth 6. Since the sealing cloth 6 is made of flexible material, in the initial state, the sealing cloth 6 is at the bend of the synchronous belt 503, so the sealing cloth 6 will not block the receiving frame 3. When the sealing cloth 6 moves to the top and bottom of the receiving frame 3, the four sealing cloths 6 simultaneously block the three receiving frames 3. Then, the limiting bolt 702 is rotated in the opposite direction, so that the limiting bolt 702 separates from the limiting hole 10, thereby pulling the filter plate 4 out from the inside of the receiving frame 3 for replacement.
