[0002] Tubular centrifuges are commonly used equipment in biopharmaceutical separation processes. Their working principle involves a motor transmitting power to the drive wheel of the drum, causing the drum to rotate at high speed around its center, creating a strong centrifugal force field. Material is injected through the bottom inlet, and the centrifugal force forces the liquid to flow upwards along the inner wall of the drum, stratifying due to density differences between its components. Denser solid particles gradually deposit on the inner wall of the drum, forming a sediment layer, while the clarified liquid phase flows to the drain outlet at the top of the drum wall and is discharged. The drum is the core component of the tubular centrifuge and requires professional heat treatment, dynamic balancing testing, and various flaw detection tests before use; high balancing accuracy is required.

[0003] In actual loading and unloading of existing tubular centrifuge drums, due to their heavy weight, the drums are mostly handled manually or lifted by cranes, requiring multiple people to work together.

[0053] This utility model discloses a loading and unloading fixture for a tubular centrifuge drum. By setting a loading and unloading lifting component and a drum clamping component on a support base, the drum clamping component is used to achieve close clamping of the drum body through a foldable clamping contact plate, while the loading and unloading lifting component is used to drive the drum clamping component to move down stably, so as to install the drum body more accurately into the centrifuge tube. This process does not require much manual labor to accurately assemble the drum body, thus improving the overall loading and unloading efficiency.

[0054] According to the tubular centrifuge drum loading and unloading fixture provided by this utility model, such as Figure 1-4The assembly includes a support base 1, a loading and unloading lifting assembly 4, and a drum clamping assembly 5. The loading and unloading lifting assembly 4 is mounted on the support base 1, and the drum clamping assembly 5 is mounted on the loading and unloading lifting assembly 4 and can move vertically under the drive of the loading and unloading lifting assembly 4. The drum clamping assembly 5 includes a clamping base 501, a clamping contact plate 508, a rotating connecting plate 503, and a fixed insert rod 507. The clamping base 501 is slidably disposed on the loading and unloading lifting assembly 4. The bottom of the clamping base 501 is provided with at least two side rotating grooves 502. The rotating connecting plate 503 can be flipped and installed in the side rotating grooves 502. The clamping contact plate 508 is installed at the bottom of the rotating connecting plate 503 for clamping the drum body 6.

[0055] When the drum clamping assembly 5 clamps the drum body 6, the rotating connecting plate 503 flips to a vertical angle, the fixing rod 507 passes through the fixing insertion hole 506 at the top of the side rotating groove 502 and is inserted into the limiting slot 505 at the top of the rotating connecting plate 503, and the clamping contact plate 508 abuts against the outer wall of the drum body 6.

[0056] The clamping contact plate 508 in the drum clamping assembly 5 can be folded and attached to both sides of the drum body, and the top of the rotating connecting plate 503 is limited and fixed by the fixing rod 507 inserted in the limiting slot 505, thereby stably clamping both sides of the drum body 6.

[0057] The above are the basic embodiments of this utility model. The following describes the solution of this utility model in further detail through several preferred embodiments.

[0058] Example 1

[0059] This embodiment discloses a tooling for loading and unloading the drum of a tubular centrifuge, such as... Figure 2 As shown, the loading and unloading lifting assembly 4 includes a lifting support plate 401, a lifting screw 403, and a driving screw sleeve 405. The clamping base 501 is fixedly installed on the driving screw sleeve 405. The lifting support plate 401 is installed on the support base 1. A lifting movable groove 402 is provided on one side of the lifting support plate 401 in the vertical direction. The lifting screw 403 is installed in the lifting movable groove 402 in the vertical direction. The driving screw sleeve 405 is sleeved on the lifting screw 403. Two limiting slide grooves 406 are symmetrically opened on both sides of the inner wall of the lifting movable groove 402. Two limiting sliders 407 are symmetrically arranged on both sides of the driving screw sleeve 405. The limiting sliders 407 are slidably inserted into the corresponding limiting slide grooves 406.

[0060] The top end of the lifting screw 403 passes through the top of the lifting movable groove 402; a drive motor 404 is provided on the top of the lifting support plate 401, and the drive shaft of the drive motor 404 is fixedly connected to the top end of the lifting screw 403. The drive motor 404 can drive the lifting screw 403 to rotate, thereby driving the lifting and lowering of the drive screw sleeve 405, which in turn drives the lifting and lowering of the drum body 6 through the drum clamping assembly 5.

[0061] Example 2

[0062] This embodiment discloses a tooling for loading and unloading the drum of a tubular centrifuge, such as... Figure 3 As shown, rotating connecting blocks 504 are provided on both sides of the top of the rotating connecting plate 503, serving as a flipping shaft; the rotating connecting plate 503 is rotatably connected to the inner wall of the side rotating groove 502 through the rotating connecting blocks 504. The drum clamping assembly 5 also includes an auxiliary contact plate 509 and a fixed connecting plate 510; the fixed connecting plate 510 is installed at the bottom of the clamping contact plate 508, and the auxiliary contact plate 509 is installed at the bottom of the fixed connecting plate 510, the auxiliary contact plate 509 being used to clamp the middle section of the drum body 6. The drum clamping assembly 5 also includes a drive connecting seat 511 and a driving connecting plate 514;

[0063] The drive connector 511 is installed on the top of the clamping base 501. The drive connector 511 has a mounting hole 512 on its side and a top side insertion opening 513 on its top wall. The drive connecting plate 514 is inserted into the mounting hole 512. The drive connecting plate 514 is slidably installed on the loading and unloading lifting assembly 4. The end of the drive connecting plate 514 has a fastening screw hole 515. The drive connecting plate 514 and the drive connector 511 are fixedly connected by a fastening screw 516. The fastening screw 516 passes through the top side insertion opening 513 and is threadedly connected to the fastening screw hole 515.

[0064] The clamping base 501 has a hollow center to accommodate the top of the drum body 6. The sides of the clamping contact plate 508 and the auxiliary contact plate 509 are curved to match the curvature of the drum body 6, ensuring that the top of the drum body 6 does not collide with the center of the clamping base 501. The top side insertion port 513, the fastening screw 516, and the fastening screw hole 515 all have the same diameter, allowing the fastening screw 516 to pass through the top side insertion port 513 and be inserted into the fastening screw hole 515, thus fixing the connecting plate 514 to the drive connecting seat 511.

[0065] Example 3

[0066] In this embodiment, a counterweight box 3 and movable wheels 2 are also included. Specifically, a counterweight box 3 is installed at the bottom of the support base 1. The counterweight box 3 is located on the side of the loading and unloading lifting assembly 4 where the drum clamping assembly 5 is not installed. It is used to counteract the force imbalance generated when clamping the drum body 6. Multiple movable wheels 2 are installed at the bottom of the support base 1. The multiple movable wheels 2 are evenly arranged circumferentially.

[0067] Working principle:

[0068] When it is necessary to load or unload the drum body 6 from the tubular centrifuge tube, the drum body 6 must first be placed at the bottom of the drum clamping assembly 5. The width of the middle part of the drum body 6 is smaller than the width of the top part, so that by rotating the rotating connecting plates 503 rotatably set on both sides of the clamping base 501, the clamping contact plates 508 connected to the bottom end of the rotating connecting plates 503 can be fitted and locked onto both sides of the middle part of the drum body 6. Then, by inserting the fixing rod 507 into the fixing hole 506, the bottom end of the fixing rod 507 is inserted into the limiting slot 505 opened at the top of the rotating connecting plate 503, which limits and fixes the rotation of the rotating connecting plate 503, ensuring that the clamping contact plate 508 is always fitted to the outer side of the middle part of the drum body 6. The auxiliary contact plate 509 and the fixing connecting plate 510 are fitted together with the clamping contact plate 508 and the drum body 6 to enhance the stability of the bottom of the drum body 6.

[0069] The top of the clamping base 501 is provided with a drive connecting seat 511, and a drive connecting plate 514 is inserted into the side of the drive connecting seat 511. The drive connecting plate 514 and the mounting hole 512 are connected and fixed by a fastening screw 516 that passes through and is inserted into the top side socket 513. This allows the drive connecting seat 511 to be connected to the drive sleeve 405 in the loading and unloading lifting assembly 4 through the drive connecting plate 514. After the drum body 6 is stably clamped, the user starts the drive motor 404 and pushes the entire device to the top of the centrifuge tube to be installed by using the moving wheels 2 at the bottom of the support base 1. The drive motor 404 then drives the lifting screw 403 to rotate, causing the drive sleeve 405 on the lifting screw 403 to move downward. The two sides of the drive sleeve 405 are limited by the limit sliders 407 inserted into the limit grooves 406, making the descent of the drum body 6 more stable.

[0070] This allows for more precise installation of the clamped and fixed drum body 6 into the centrifuge tube. The loading and unloading process requires less manual labor, makes the transfer and installation of the drum body 6 more convenient, and effectively improves the assembly accuracy of the drum body 6, ensuring smoother operation of the installed drum body 6 and greatly improving the overall loading and unloading efficiency.
