Description

Technical Field

[0001] This application relates to the field of food and pharmaceutical packaging technology, and in particular to a virus removal filtration device. Background Technology

[0002] Common methods for virus removal / inactivation include devirtual filtration and low-pH virus inactivation. Low-pH virus inactivation primarily inactivates lipid-enveloped viruses. The removal of non-lipid-enveloped viruses is usually achieved through physical methods because they are highly resistant to chemical inactivation. Devirtual filtration systems are needed to remove non-lipid-enveloped viruses generated during the purification process of biopharmaceutical products. Devirtual filtration systems can remove both non-lipid-enveloped and lipid-enveloped viruses.

[0003] For example, the virus removal filtration device and system described in patent number CN202122324180.7 have the following shortcomings in actual use:

[0004] The aforementioned device includes a mounting frame, a support, and a virus-removing filter mounted on the mounting frame. The mounting frame is rotatably adjustable on the support. An angle locking mechanism is provided between the mounting frame and the support to lock their angle. The angle locking mechanism includes a locking element and a resilient reset element. The support has an arc-shaped groove, the center of which is concentric with the rotation center of the mounting frame. The locking element passes through the arc-shaped groove and is movably inserted into the mounting frame. The resilient reset element is located between the mounting frame and the locking element. This design has advantages such as facilitating angle adjustment and integrity testing. However, when using the device, the angle of the mounting frame needs to be unlocked and adjusted before locking again, which is inconvenient. Summary of the Invention

[0005] To address the technical problem of inconvenient angle adjustment of the mounting bracket for virus removal filters, this application provides a virus removal filter device.

[0006] The virus removal and filtering device provided in this application adopts the following technical solution:

[0007] A virus-removing filter includes a mounting frame and a support. A fixing plate is fixed on the mounting frame, and a handle and a virus-removing filter are provided on the fixing plate. The lower end of the fixing plate is right-angled, and a rotating shaft is fixed to the lower end of the fixing plate. A rotating hole is provided on the support, and the rotating shaft is rotatably disposed in the rotating hole. A sliding sleeve is slidably fitted on the handle, and a horizontal plate is fixed to the bottom of the sliding sleeve. A limit rod is fixed to the lower end of the horizontal plate, and the lower end of the limit rod slides through the fixing plate. An arc-shaped plate is fixed inside the support, and a plurality of positioning holes are provided on the arc-shaped plate. The bottom of the limit rod is inserted into one of the positioning holes.

[0008] By adopting the above technical solution, the operator can hold the handle and slide the sliding sleeve upwards. At this time, the sliding sleeve drives the limiting rod to move upwards, so that the bottom of the limiting rod is pulled out of the positioning hole. Then, the operator can drive the mounting bracket to rotate by the handle. After adjusting to the appropriate angle, the limiting rod is aligned with another positioning hole. Then, the sliding sleeve is slid downwards to insert the limiting rod into the positioning hole, which can be fixed again to secure the mounting bracket. This can be operated by a single person, making the operation more convenient.

[0009] Preferably, a limit block is fixed on the inner side of the support, and a notch is provided on the side end of the fixing plate, and a stop bar is fixed on the fixing plate.

[0010] By adopting the above technical solution, when the fixed plate rotates to the maximum angle in one direction, the bottom of the fixed plate will be blocked by the limiting block. Similarly, when the fixed plate rotates to the maximum angle in the opposite direction, the limiting block will pass through the notch and abut against the stop bar, which can limit the maximum rotation angle of the mounting frame and prevent the mounting frame from being damaged due to being out of the operator's control during rotation.

[0011] Preferably, the handle is provided with a groove, and a retaining ring is provided below the groove, with the retaining ring located above the sliding sleeve.

[0012] By adopting the above technical solution, when the operator holds the handle, he can press his thumb into the groove, which makes it easier for the operator to slide the slide upward with the help of the groove. The operation is more convenient. Moreover, the upward sliding of the slide is blocked by the retaining ring, so it will not cause any damage or squeezing to the operator's fingers.

[0013] Preferably, the outer side of the sliding sleeve is provided with a plurality of equally spaced anti-slip patterns.

[0014] By adopting the above technical solution, the anti-slip texture can prevent the operator's hand from slipping on the sliding sleeve, further improving the operating experience.

[0015] Preferably, a bushing is fixed to the bottom of the fixing plate, and a limiting rod passes through the bushing and is slidably connected to the bushing.

[0016] By adopting the above technical solution, the bushing can improve the stability of the limiting rod and prevent the limiting rod from shaking with the fixed plate, thereby improving the stability of the device.

[0017] Preferably, the inner walls on both sides of the support are provided with arc-shaped grooves, and both sides of the arc-shaped plate are slidably disposed in the arc-shaped grooves. One side of the support is provided with a plurality of threaded holes, and fastening bolts are provided in the threaded holes, with the ends of the fastening bolts abutting against the arc-shaped plate.

[0018] By adopting the above technical solution, the arc plate can slide along the arc groove and be fixed by tightening the fastening bolts, thereby adjusting the position of the arc plate. After adjusting the position of the arc plate, the positioning hole moves synchronously, which can expand the adjustable angle of the mounting bracket and make the adjustable angle more comprehensive.

[0019] Preferably, the arc-shaped plate is provided with an anti-slip groove at the end away from the threaded hole, and an anti-slip rubber pad is provided in the arc-shaped groove near the anti-slip groove.

[0020] By adopting the above technical solution, when the fastening bolts tighten the arc plate, the side of the arc plate with the anti-slip groove is pressed against the anti-slip rubber pad, which can prevent the arc plate from slipping and improve the stability of the device.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The operator holds the handle and slides the sliding sleeve upward to pull the limit rod out of the positioning hole. After adjusting the angle of the mounting bracket, the operator slides the sliding sleeve downward to insert the limit rod into another positioning hole to fix the mounting bracket. This allows for angle adjustment of the virus removal filter. The operation is simple and can be done with one hand, effectively improving work efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a virus filtering device.

[0031] Reference Figure 1 , 2 3. A virus-removing filter device includes a mounting frame 1 and a support 5. A fixing plate 2 is fixed on the mounting frame 1. A handle 4 and a virus-removing filter 3 are provided on the fixing plate 2. A sliding sleeve 8 is slidably fitted on the handle 4. The sliding sleeve 8 is provided with anti-slip texture 18 to prevent slippage. A groove 16 is provided on the handle 4, and a retaining ring 17 is provided below the groove 16. The retaining ring 17 is located above the sliding sleeve 8. The lower end of the fixing plate 2 is right-angled, and a rotating shaft 6 is fixed to the lower end of the fixing plate 2. A rotating shaft 6 is provided on the support 5. Hole 7, fixing plate 2 is hinged to support 5 via rotating shaft 6, bushing 19 is fixed to the lower end of fixing plate 2, horizontal plate 12 is fixed to the bottom of sliding sleeve 8, limit rod 9 is fixed to the lower end of horizontal plate 12, and the distance between limit rod 9 and rotating shaft 6 is less than the distance between sliding sleeve 8 and rotating shaft 6. The lower end of limit rod 9 slides through fixing plate 2 and bushing 19. Arc plate 10 is fixed inside support 5, and several positioning holes 11 are provided on arc plate 10, and the bottom of limit rod 9 is inserted into one of the positioning holes 11.

[0032] With the above setup, the operator can hold the handle 4 and press their thumb into the groove 16. Using the groove 16 as leverage, the sliding sleeve 8 can be slid upwards. The sliding sleeve 8 will be blocked by the retaining ring 17, preventing the operator's fingers from being squeezed. The sliding sleeve 8 drives the limiting rod 9 to move upwards, causing the bottom of the limiting rod 9 to be pulled out of the positioning hole 11. At this point, the mounting bracket 1 can be rotated by the handle 4. After adjusting to an appropriate angle, the limiting rod 9 is aligned with another positioning hole 11. Then, the sliding sleeve 8 is slid downwards, inserting the limiting rod 9 into the positioning hole 11. The rotation of the limiting rod 9 is restricted, and the fixing plate 2 can be fixed again, thereby fixing the mounting bracket 1. This can be operated by a single person, making the operation more convenient.

[0033] Furthermore, the bushing 19 can improve the stability of the limiting rod 9 and prevent the limiting rod 9 from shaking with the fixed plate 2, thereby improving the stability of the device.

[0034] Reference Figure 3 , 4 A limit block 13 is fixed on the inner side of the support 5, and a notch 14 is provided on the side end of the fixing plate 2. A stop bar 15 is fixed on the fixing plate 2, and the stop bar 15 is located just outside the notch 14.

[0035] With the above settings, when the fixed plate 2 rotates to the maximum angle in one direction, the bottom of the fixed plate 2 will be blocked by the limiting block 13. Similarly, when the fixed plate 2 rotates to the maximum angle in the opposite direction, the limiting block 13 will pass through the notch 14 and abut against the stop bar 15, which can limit the maximum rotation angle of the mounting bracket 1 and prevent the mounting bracket 1 from getting out of the operator's control during rotation, resulting in excessive rotation angle and damage, thus playing a certain protective role.

[0036] Reference Figure 4 , 5 The inner walls of both sides of the support 5 are provided with arc-shaped grooves 20. Both sides of the arc-shaped plate 10 are slidably disposed in the arc-shaped grooves 20. The arc-shaped plate 10 can slide out from one end of the arc-shaped groove 20 for easy installation and disassembly. One of the arc-shaped grooves 20 is provided with an anti-slip rubber pad 23, and the side end of the arc-shaped plate 10 near the anti-slip rubber pad 23 is provided with several anti-slip grooves 24. The side of the support 5 away from the anti-slip rubber pad 23 is provided with several threaded holes 21, and fastening bolts 22 are provided in the threaded holes 21. The ends of the fastening bolts 22 abut against the arc-shaped plate 10, pressing the arc-shaped plate 10 together and fixing the arc-shaped plate 10 by friction.

[0037] With the above settings, the arc plate 10 can slide along the arc groove 20 and be fixed by tightening the fastening bolt 22. After fixing, the arc plate 10 abuts against the anti-slip rubber pad 23, which provides high stability. This allows the position of the arc plate 10 to be adjusted. After adjusting the position of the arc plate 10, the positioning hole 11 moves synchronously. The operator can fix the position of the arc plate 10 at the required angle, thereby expanding the adjustable angle of the mounting bracket 1 and making the adjustable angle more comprehensive.

[0038] The implementation principle of the virus removal filtering device in this application embodiment is as follows: The operator can hold the handle 4 and press their thumb into the groove 16. Using the groove 16 as leverage, the sliding sleeve 8 is slid upward. The sliding sleeve 8 is blocked by the retaining ring 17, preventing the operator's fingers from being squeezed. The sliding sleeve 8 drives the limiting rod 9 to move upward, so that the bottom of the limiting rod 9 is pulled out from the positioning hole 11. At this time, the mounting bracket 1 can be rotated by the handle 4. After adjusting to an appropriate angle, the limiting rod 9 is aligned with another positioning hole 11. Then, the sliding sleeve 8 is slid downward to insert the limiting rod 9 into the positioning hole 11. The rotation of the limiting rod 9... With the restriction removed, the fixing plate 2 can be fixed again to secure the mounting bracket 1. This can be operated by a single person, making the operation more convenient. The arc plate 10 can slide along the arc groove 20 and is fixed by tightening the fastening bolt 22. After fixing, the arc plate 10 abuts against the anti-slip rubber pad 23, resulting in high stability. This allows for adjustment of the position of the arc plate 10. After adjusting the position of the arc plate 10, the positioning hole 11 moves synchronously. The operator can fix the position of the arc plate 10 at the required angle, expanding the adjustable angle of the mounting bracket 1 and making the adjustable angle more comprehensive.

[0039] In summary, this device can adjust the angle of the virus removal filter 3. The operation is simple and can be done with one hand, which can effectively improve work efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
