Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a high-cleanliness capsule filter. Background Technology

[0002] In industries such as pharmaceuticals, food, and electronics, where extremely high fluid purity is required, capsule filters are widely used in the fine filtration of liquids due to their excellent filtration efficiency and ease of use. These filters typically connect to a delivery pipeline at both ends to achieve fluid filtration and purification. However, when the filter reaches the end of its service life and needs replacement, it is inevitable to remove the old filter from the pipeline. During the installation of the new filter, impurities adhering to the pipeline port can enter the filtration system along with the new filter's connection to the pipeline. This not only affects the initial filtration effect of the new filter but may also introduce impurities into the fluids being processed, posing a potential risk to product quality. Especially in scenarios such as pharmaceutical filtration and ultrapure water filtration in the electronics industry, even trace amounts of impurities can cause serious quality problems, even leading to batch product non-compliance. Therefore, this invention proposes a high-cleanliness capsule filter. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where, when replacing filters, pipe ports are easily contaminated with impurities. These impurities can enter the filtration system, affecting the effectiveness of the new filter and potentially mixing into the fluid, posing a risk to product quality. This invention proposes a high-cleanliness capsule filter.

[0005] Optionally, the clamping mechanism includes a fixing block fixedly connected to the fixing frame near the filter body. A threaded cylinder is fixedly connected to one end of the fixing block. Two sets of threaded rods are threadedly connected to the threaded cylinder. The two sets of threaded rods are located at both ends of the threaded cylinder, and the thread directions of the two sets of threaded rods are opposite. The threaded rods pass through the extrusion plate and rotate with it. Two sets of limiting rings are fixedly connected to the threaded rods. The two sets of limiting rings are located on both sides of the extrusion plate.

[0006] Optionally, the fixing frame is fixedly connected to a plurality of first fixing cylinders on the side near the filter body, and two sets of first sliding rods are slidably connected in the first fixing cylinders, and the two sets of first sliding rods are respectively fixedly connected to a set of extrusion plates.

[0007] Optionally, a linkage rod is slidably connected to the two sets of threaded rods. The linkage rod is a regular square prism. The outer ring of the linkage rod is rotatably connected to two sets of positioning plates through bearings. The two sets of positioning plates are located on the side away from the two sets of extrusion plates. The positioning plates are fixedly connected to the fixing frame. A rotating handle is fixedly connected to one end of the linkage rod.

[0008] Optionally, the protective assembly includes two sets of fixing plates fixedly connected to one side of the two sets of extrusion plates. The two sets of fixing plates are symmetrically arranged and located outside the connecting nozzle. The fixing plates are L-shaped. Limiting strips are fixedly connected to the opposite sides of the two sets of fixing plates. A baffle is slidably connected between the fixing plates and the limiting strips.

[0009] Optionally, the synchronization mechanism includes multiple sets of arc-shaped plates that fit against the outer side of the filter body.

The baffle does not contact the connecting nozzle, thus preventing external dust and impurities from directly entering the connecting nozzle. Furthermore, when installing the new filter body, the filter body pushes the arc plate and the moving plate, and through the second fixed cylinder and the second sliding rod, the baffle automatically moves away from the connecting nozzle, ensuring that the connection between the connecting pipe and the connecting nozzle is not disturbed, fundamentally reducing the risk of impurities entering the filtration system and ensuring the purity of the filtration system; In summary, this invention can prevent impurities from entering the filtration system when replacing the filter, ensuring fluid purity to meet high industry requirements, and also simplifies operation and improves replacement efficiency.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, the present invention proposes a high-cleanliness capsule filter, which includes a filter body 1 and connecting pipes 11 disposed at both ends of the filter body 1. This is the prior art and will not be described in detail here.

[0021] Furthermore, the filter mentioned above includes a mounting bracket 2 located on one side of the filter body 1, and the mounting bracket 2 is fixedly installed.

[0022] Furthermore, the filter also includes two sets of extrusion plates 3 disposed at both ends of the filter body 1. The extrusion plates 3 are fixedly connected with connecting nozzles 31 corresponding to the positions of the connecting pipes 11. When the two sets of extrusion plates 3 approach the filter body 1, the connecting nozzles 31 are locked in the positions of the connecting pipes 11, and the filter body 1 is clamped and fixed after approaching.

[0023] For details, please refer to Figures 1 to 4 The filter includes a clamping mechanism 4 mounted on the side of the mounting frame 2. The clamping mechanism 4 is used to clamp and fix the filter body 1 by driving the extrusion plate 3. The clamping mechanism 4 includes a fixing block 41 fixedly connected to the side of the mounting frame 2 near the filter body 1. A threaded cylinder 42 is fixedly connected to one end of the fixing block 41, and the position of the threaded cylinder 42 is fixed. Two sets of threaded rods 43 are threadedly connected in the threaded cylinder 42. Since the position of the threaded cylinder 42 is fixed, the threaded rods 43 move along their own length direction when they rotate. The two sets of threaded rods 43 are located at both ends of the threaded cylinder 42, and the thread directions of the two sets of threaded rods 43 are opposite. When the two sets of threaded rods 43 rotate synchronously, their movement directions are opposite. The threaded rods 43 pass through the extrusion plate 3 and rotate with it. Two sets of limiting rings 44 are fixedly connected to the threaded rods 43. The two sets of limiting rings 44 are located on both sides of the extrusion plate 3. When the threaded rods 43 rotate and move, they drive the extrusion plate 3 to move. Multiple sets of first fixing cylinders 45 are fixedly connected to the side of the mounting frame 2 near the filter body 1, and the position of the first fixing cylinders 45 is fixed. Two sets of first sliding rods 46 are slidably connected in the first fixed cylinder 45. Each set of first sliding rods 46 is fixedly connected to a set of extrusion plates 3. The limiting effect of the first fixed cylinder 45 and the first sliding rods 46 ensures smooth movement of the extrusion plates 3. A linkage rod 47 is slidably connected in the two sets of threaded rods 43. The linkage rod 47 is a regular square prism, which allows the two sets of threaded rods 43 to rotate synchronously when the linkage rod 47 rotates, while the threaded rods 43 can slide on the linkage rod 47. Two sets of positioning plates 48 are rotatably connected to the outer ring of the linkage rod 47 via bearings. The two sets of positioning plates 48 are located on the side of the two extrusion plates 3 furthest apart. The positioning plates 48 are fixedly connected to the fixed frame 2, allowing the linkage rod 47 to rotate in its original position. A rotating handle 49 is fixedly connected to one end of the linkage rod 47, facilitating rotation of the linkage rod 47. Furthermore, such as Figure 4 and Figure 5As shown, the filter includes a protective assembly 5 disposed between two sets of extrusion plates 3. The protective assembly 5 is used to protect the connecting nozzle 31 when the filter body 1 is removed. The protective assembly 5 includes two sets of fixing plates 51 fixedly connected to the adjacent side of the two sets of extrusion plates 3. The two sets of fixing plates 51 are symmetrically arranged and located outside the connecting nozzle 31. The fixing plates 51 are L-shaped. Limiting strips 52 are fixedly connected to the opposite sides of the two sets of fixing plates 51. A baffle 53 is slidably connected between the fixing plates 51 and the limiting strips 52. The baffle 53 is limited by the setting of the fixing plates 51 and the limiting strips 52, so that the baffle 53 moves smoothly. After the baffle 53 moves to the position of the connecting nozzle 31, the baffle 53 does not contact the connecting nozzle 31, preventing dust on the baffle 53 from being scraped into the connecting nozzle 31. At the same time, since the connecting nozzle 31 directly blocks the position of the connecting nozzle 31, it can prevent external dust and impurities from directly entering the connecting nozzle 31 to a certain extent, ensuring the purity of the filtration system.

[0024] Furthermore, such as Figure 2 , Figure 3 and Figure 6As shown, the filter includes a synchronization mechanism 6, which coordinates the positions of the filter body 1 and the protective assembly 5. The synchronization mechanism 6 includes multiple sets of arc-shaped plates 61 that fit against the outer side of the filter body 1. A movable plate 62 is fixedly connected to each of the multiple sets of arc-shaped plates 61 near the fixing frame 2, and the arc-shaped plates 61 and the movable plate 62 move synchronously. Multiple sets of second fixing cylinders 63 are fixedly connected to the movable plate 62 near the fixing frame 2. Two sets of second sliding rods 64 are slidably connected within the second fixing cylinders 63, and each set of second sliding rods 64 is fixedly connected to a baffle 53. When the arc-shaped plates 61 and the movable plate 62 move, the second fixing cylinders 63 and the second sliding rods 64 drive the baffle 53 to move synchronously. Therefore, when the filter body 1 is installed, after the filter body 1 contacts the arc-shaped plates 61, when the connecting pipe 11 moves to the connecting nozzle 31 position, the baffle 53 has completely left the connecting nozzle 31 position and will not affect the combination of the connecting pipe 11 and the connecting nozzle 31. Meanwhile, the sliding engagement between the second slide rod 64 and the second fixed cylinder 63 ensures the connection between the moving plate 62 and the baffle 53 when the extrusion plate 3 moves and drives the baffle 53 to move. Multiple sets of elastic support assemblies 65 are fixedly connected between the moving plate 62 and the fixed frame 2. The elastic support assemblies 65 are used to release elastic force, facilitating the movement of the baffle 53 to the connection nozzle 31 position after the filter body 1 is removed. Each elastic support assembly 65 includes a first sleeve 651 fixedly connected to the fixed frame 2, a first limiting plate 652 slidably connected to the first sleeve 651, a first spring 653 installed in the first sleeve 651 on the side of the first limiting plate 652 near the fixed frame 2, and a second sleeve 654 fixedly connected to the side of the first limiting plate 652 away from the first spring 653. The second sleeve 654 is slidably connected to the first sleeve 651, and a second limiting plate 655 slidably connected to the second sleeve 654. A second limiting plate 655 is installed in the side of the second limiting plate 655 near the first limiting plate 652. The second spring 656 in the second sleeve 654 and the second limiting plate 655 are fixedly connected to the side away from the second spring 656. The connecting rod 657 is slidably connected to the second sleeve 654. One end of the connecting rod 657 is fixedly connected to the moving plate 62. The arrangement of the first spring 653 and the second spring 656 effectively increases the stroke of the connecting rod 657. After the filter body 1 is taken out, the elastic force of the first spring 653 and the second spring 656 drives the moving plate 62 away from the fixed frame 2, thereby causing the baffle 53 to move to the position of the connecting nozzle 31 for covering.

[0025] In this embodiment, when installing the filter body 1, the rotating handle 49 in the clamping mechanism 4 is rotated first, causing the linkage rod 47 to rotate. Since the linkage rod 47 is a regular square prism and is slidably connected to two sets of threaded rods 43, its rotation will cause the two sets of threaded rods 43 to rotate synchronously. The threaded rods 43 are threadedly connected to the threaded cylinder 42 on the fixed block 41, and the threads of the two sets of threaded rods 43 are opposite in direction. When the position of the threaded cylinder 42 is fixed, the two sets of threaded rods 43 will move in opposite directions along their own length. The threaded rods 43 drive the extrusion plate 3 to move through the limiting ring 44. At the same time, the cooperation between the first fixed cylinder 45 and the first sliding rod 46 ensures the smoothness of the movement of the extrusion plate 3, making the two sets of extrusion plates 3 move away from each other, leaving space for the filter body 1 to be inserted.

[0026] The filter body 1 is placed between the two sets of extrusion plates 3, and its outer side contacts the arc-shaped plate 61 in the synchronization mechanism 6. As the filter body 1 is placed, it pushes the arc-shaped plate 61 to move closer to the fixed frame 2. The arc-shaped plate 61 drives the moving plate 62 to move synchronously. The moving plate 62 compresses the elastic support assembly 65, causing the first spring 653 in the first sleeve 651 and the second spring 656 in the second sleeve 654 to be compressed. The first limiting plate 652 and the second limiting plate 655 slide accordingly. At the same time, the moving plate 62 drives the baffle 53 in the protective assembly 5 to move through the cooperation of the second fixed cylinder 63 and the second sliding rod 64. The baffle 53 slides smoothly under the limiting action of the fixed plate 51 and the limiting strip 52, gradually moving away from the connecting nozzle 31.

[0027] Once the filter body 1 is in place, rotate the handle 49 in the opposite direction. The linkage rod 47 drives the two sets of threaded rods 43 to rotate synchronously in the opposite direction, causing the two sets of extrusion plates 3 to move closer to each other. The connecting nozzles 31 on the extrusion plates 3 gradually engage with the connecting pipes 11 at both ends of the filter body 1, ultimately clamping and fixing the filter body 1. At this point, the baffle 53 has completely disengaged from the connecting nozzles 31, without affecting the normal connection between the connecting pipes 11 and the connecting nozzles 31.

[0028] When the filter body 1 needs to be replaced, rotate the handle 49 to move the two sets of extrusion plates 3 away from each other, separating the connecting nozzle 31 from the connecting pipe 11. After removing the old filter body 1, the first spring 653 and the second spring 656 in the elastic support assembly 65 release their elastic force, pushing the first limiting plate 652, the second limiting plate 655, and the connecting rod 657 to move, thereby driving the moving plate 62 and the arc-shaped plate 61 to move away from the fixed frame 2. The moving plate 62 drives the baffle 53 to move in the opposite direction through the second fixed cylinder 63 and the second sliding rod 64. Under the limitation of the fixed plate 51 and the limiting strip 52, the baffle 53 moves to the position of the connecting nozzle 31, covering the connecting nozzle 31. Since the baffle 53 does not contact the connecting nozzle 31, dust is prevented from scraping into the connecting nozzle 31, effectively preventing external dust and impurities from entering the connecting nozzle 31, ensuring the cleanliness of the pipe port, and providing a clean environment for the installation of the new filter body 1.

[0029] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
