Abstract

This utility model relates to the field of chromatographic column packing technology, specifically a tooling for packing chromatographic column packing. It includes a support base plate, a shaker, hydraulic dampers, a mounting plate, a mounting frame, a feed funnel, a transfer pipe, a connector, and a fixing assembly. The support base plate is connected to the shaker, which is connected to multiple hydraulic dampers. One end of each hydraulic damper is connected to the mounting plate. Two mounting frames are arranged in parallel and connected to the support base plate. The feed funnel is connected to each mounting frame. The fixing assembly is connected to the mounting plate. In this utility model, after the chromatographic column is placed into the limiting cylinder, the fixing assembly effectively limits the position of both ends of the column.

This allows the sealing structure used to seal the column to be installed and disassembled normally during clamping, reducing the steps and time required for stepped packing.

Description

Technical Field

[0001] This utility model relates to the field of chromatographic column packing technology, and specifically to a tooling for packing chromatographic column packing. Background Technology

[0002] A chromatographic column is a tube packed with a stationary phase to separate mixed components. The inside is filled with "packing material" for detecting air components, and the air is easily detected after passing through the tube.

[0003] Chinese Patent No. CN220305247U discloses a tooling for packing chromatographic columns, including a stabilizing plate. A vibrator is fixedly connected to the top of the stabilizing plate, and limiting seats are fixedly connected to all four sides of the top of the vibrator. A spring is fixedly connected to the bottom of the inner cavity of the limiting seat. This invention positions the chromatographic column by placing it in the inner cavity of the fixing frame and rotating the threaded rod, which in turn moves the positioning plate downwards. The column is then connected to the chromatographic column via a connecting pipe. The packing material in the storage hopper can be transferred to the inner cavity of the chromatographic column through the transfer pipe and connecting pipe. The vibrator generates vibration force, which causes the spring to deform and reset, allowing the support plate to shake the chromatographic column. This effectively prevents the time-consuming and laborious process of manually tapping the column to pack it, as repeated tapping can easily damage the column and affect its service life.

[0004] However, in the above technical solution, the positioning plate can be moved downward by rotating the threaded rod, thereby achieving the positioning of the chromatographic column. However, in dry packing, it is necessary to use a combination of distributed packing and segmented compaction, rather than packing in one go. Therefore, if frequent packing is required, the position of the positioning plate needs to be adjusted and the connecting tube needs to be disassembled and reassembled. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a tooling for packing chromatographic column packing materials.

[0006] The technical solution of this utility model is as follows: A tooling for packing chromatographic column packing includes a supporting base plate connected to a shaker, with multiple hydraulic dampers connected to the shaker, and a mounting plate connected to one end of each hydraulic damper; two mounting frames arranged in parallel, connected to the supporting base plate, with a feed funnel connected to the mounting frame, a transfer pipe connected to the feed funnel, and a connector connected to the transfer pipe; and a fixing assembly connected to the mounting plate, comprising a mounting seat, an adjusting plate, a moving block, and grippers. The mounting seat is connected to the mounting plate and has a receiving cavity. The adjusting plate is rotatably connected to the receiving cavity, and has multiple eccentric grooves. Grippers are slidably connected to the eccentric grooves, and the mounting seat has guide grooves for the grippers to pass through. In use, the eccentric grooves of the adjusting plate rotate, pushing the grippers to move linearly along the guide grooves, and the grippers move towards the center of the mounting seat to clamp and fix the chromatographic column.

[0007] Preferably, the fixing assembly further includes an adjusting rod, one end of which is connected to the adjusting disc and the other end of which passes through the mounting base; and a self-locking member connected to the adjusting handle, wherein the self-locking member and the mounting base have a notch for sliding connection through the adjusting rod.

[0008] Preferably, the self-locking component consists of a movable sleeve and a limiting block. The movable sleeve is threadedly connected to the adjusting rod, and the limiting block is connected to one end of the movable sleeve. The limiting block is slidably connected to a notch on the mounting base.

[0009] Preferably, each of the grippers is connected to a wedge-shaped block at its top, and the lower end face of the wedge-shaped block has an inclined surface that contacts the chromatographic column.

[0010] Preferably, the mounting base consists of a fixed plate and a frame. The fixed plate is connected to the mounting plate, and the frame is detachably connected to the fixed plate. A cavity for accommodating the adjustment disc is provided on the frame, a guide groove is provided on the frame, and a notch for the adjustment rod is provided on the frame.

[0011] Preferably, the guide groove has a stepped structure, and an auxiliary block is slidably connected inside the guide groove, with the auxiliary block connected to the gripper.

[0012] Preferably, a connecting cylinder is connected to the mounting plate, and the connecting cylinder is connected to a limiting cylinder by a thread, and the limiting cylinder has a cavity for accommodating the chromatographic column.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, after the chromatographic column is placed into the limiting cylinder, the fixing component is used to limit the two ends of the chromatographic column. At the same time, the wedge-shaped blocks set on the grippers not only fix and position the column, but also avoid obstructing the connector through their own clearance grooves. This allows the sealing structure used to seal the chromatographic column to be installed and disassembled normally during the clamping operation, reducing the steps and time required for stepped packing.

[0020] Example 1

[0021] like Figures 1-4 As shown, the present invention proposes a tooling for packing chromatographic column packing materials, including a support base plate 1, a shaker 2, a hydraulic damper 3, a mounting plate 4, a mounting frame 5, a feed funnel 6, a transfer pipe 7, a connector 8, and a fixing assembly. The support base plate 1 is connected to the shaker 2, and multiple hydraulic dampers 3 are connected to the shaker 2. One end of each hydraulic damper 3 is connected to the mounting plate 4. Two mounting frames 5 are arranged in parallel and are connected to the support base plate 1.

[0022] In an optional embodiment, the mounting base 9 consists of a fixing plate 19 and a frame 20. The fixing plate 19 is connected to the mounting plate 4, and the frame 20 is detachably connected to the fixing plate 19. A cavity for accommodating the adjusting plate 10 is provided on the frame 20, a guide groove is provided on the frame 20, and a notch for the adjusting rod 14 is provided on the frame 20.

[0023] The mounting bracket 5 is connected to the feed funnel 6, the feed funnel 6 is connected to the transfer pipe 7, and the transfer pipe 7 is connected to the connector 8. The fixing assembly is connected to the mounting plate 4. The fixing assembly includes a mounting base 9, an adjusting plate 10, a moving block 11, and a clamp 12. The mounting base 9 is connected to the mounting plate 4 and has a receiving cavity. The adjusting plate 10 is rotatably connected to the receiving cavity. The adjusting plate 10 has multiple eccentric grooves 13, and the clamp 12 is slidably connected to the eccentric grooves 13. The mounting base 9 has a guide groove for the clamp 12. When the fixing assembly is in use, the eccentric grooves 13 of the adjusting plate 10 rotate and push the clamp 12 to move linearly along the guide groove. The clamp 12 moves towards the center of the mounting base 9 to clamp and fix the chromatographic column.

[0024] Example 2

[0025] like Figures 2-4 As shown, the present invention proposes a tooling for packing chromatographic column packing. Compared with Embodiment 1, this embodiment describes the detailed structure of the fixing component. The fixing component also includes an adjusting rod 14 and a self-locking member 15. One end of the adjusting rod 14 is connected to the adjusting plate 10, and the other end of the adjusting rod 14 passes through the mounting base 9. The self-locking member 15 is connected to the adjusting handle, and the self-locking member 15 and the mounting base 9 are provided with notches for sliding connection through the adjusting rod 14.

[0026] In an optional embodiment, the self-locking component 15 consists of a movable sleeve 16 and a limiting block 17. The movable sleeve 16 is threadedly connected to the adjusting rod 14, and the limiting block 17 is connected to one end of the movable sleeve 16. The limiting block 17 is slidably connected to the notch on the mounting base 9.

[0027] In an optional embodiment, each of the grippers 12 is connected to a wedge block 18 at its top. The lower end face of the wedge block 18 is provided with an inclined surface that contacts the chromatographic column. An avoidance groove is provided on the wedge block 18. The avoidance groove facilitates direct operation of the chromatographic column, eliminating the need to loosen the grippers 12 or fix the structure when disassembling and assembling the sealing structure during stepped filling.

[0028] In an optional embodiment, the guide groove has a stepped structure, and an auxiliary block 21 is slidably connected in the guide groove. The auxiliary block 21 is connected to the gripper 12. The auxiliary block 21 slides in the guide groove to limit the movement of the gripper 12 and prevent it from rotating to maintain its angle.

[0029] In an optional embodiment, a connecting cylinder 22 is connected to the mounting plate 4. The connecting cylinder 22 is connected to a limiting cylinder 23 by a thread. The limiting cylinder 23 has a cavity for accommodating the chromatographic column. The limiting cylinder 23, together with the fixing component, can restrict and fix both ends of the chromatographic column to prevent damage to the chromatographic column container when the shaker 2 is working.

[0030] In summary, when using this utility model, the chromatographic column is placed inside the limiting cylinder 23, and then the adjusting rod 14 is pulled to drive the adjusting plate 10 to rotate. The position of the eccentric groove 13 on the adjusting plate 10 changes, pushing the clamp 12 and the auxiliary block 21 to slide linearly along the guide groove towards the center position of the mounting base 9. While the clamp 12 clamps the side wall of the chromatographic column, the wedge block 18 restricts the vertical movement of the chromatographic column through the inclined surface at its top. Then, when the moving sleeve 16 is rotated, the limiting block 17 is inserted into the notch opened on the frame 20 for locking. The operator can connect the connector 8 to the chromatographic column for packing. After packing, the connector 8 is removed and the sealing structure is connected to the chromatographic column. The notch of the wedge block 18 and the setting of the clamp 12 allow the sealing structure to be disassembled and assembled without the clamp 12 being loosened. After the sealing structure is installed, the shaker 2 is started to shake. Then the sealing structure is removed again and the connector 8 is connected for packing again. This process is repeated to complete the packing work.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
