Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical industry, and specifically relates to a pressurized column chromatography device. Background Technique

[0002] The working principle of the pressurized column chromatography device is to dissolve the mixture in the mobile phase under high pressure and then separate it through the stationary phase filled in the column. After passing through the column, different compounds will be separated due to their different affinities for the stationary phase. This technology can separate high-purity target compounds and is usually used for extracting organic compounds from natural products, purifying and separating synthetic compounds.

[0003] The advantages of the pressurized chromatography column are its high separation efficiency, fast separation speed, and small sample requirement. In addition, the pressurized chromatography column can also adapt to the separation requirements of different compounds by changing the mobile phase, column filler, and operating conditions. Therefore, it is widely used in the separation and purification processes of various types of compounds. In the chemical industry, the pressurized chromatography column is used to purify specific compounds from complex mixtures to meet the needs of industrial production.

The top of the chromatography column is fixedly provided with a liquid addition pipe, the top of the liquid addition pipe is fixedly installed with a liquid storage pipe, and the top of the liquid storage pipe is hermetically penetrated with a rubber plug.

[0005] Although the above patent can clamp and fix the chromatography column by setting a clamping mechanism in the pressurized column chromatography device, the base, fixed sleeve, support rod, and clamping mechanism are fixedly arranged. Therefore, when not in use, it occupies a large space and is not convenient for storage. In view of this, the present utility model is proposed. Content of the Utility Model

[0006] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a pressurized column chromatography device that can overcome or at least partially solve the above problems.

[0008] Further, the lifting assembly is an electric telescopic rod.

[0009] Further, the clamping assembly includes a clamping seat, a bidirectional lead screw, and clamping plates. The clamping seat is detachably connected to the rotating rod through threads. A slot is provided on the side of the clamping seat away from the rotating rod. The bidirectional lead screw is rotatably connected in the slot.

A rotating handle is rotatably connected to one side of the clamping seat, and the rotating handle is fixedly connected to one end of the bidirectional lead screw. Rubber pads are fixedly connected to the adjacent sides of the two clamping plates.

[0010] To facilitate the stable placement of the rotating rod inside the storage box, furthermore, a fixing ring for making the rotating rod parallel to the lifting assembly after folding is fixedly connected to the top of the lifting assembly, and the upper surface of the fixing ring is flush with the upper surface of the electromagnet block.

[0011] To facilitate the staff to carry the device by pulling the handle, further, two groups of first magnetic strips are symmetrically and embeddedly installed at the opening end of the storage box, second magnetic strips attracted to the first magnetic strips are embeddedly installed on the cover plate, and a pulling handle is fixedly installed on one side of the storage box.

[0012] To facilitate improving the stability of the device when placed on the workbench, further, rubber legs are fixedly connected to the four corners at the bottom of the storage box.

Specific Embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0022] Embodiment 1:

[0023] Referring to Figures 1 - 4 , a pressure column chromatography device includes a chromatography column body 1, and further includes: a storage box 2, with cover plates 201 symmetrically and rotatably connected to the opening of the storage box 2; a lifting assembly 3, rotatably connected to one side inside the storage box 2, and the cover plate 201 is provided with a notch for cooperating with the lifting assembly 3; a rotating rod 302, rotatably connected to the top of the lifting assembly 3; an electromagnet 303, embedded and installed at the top of the lifting assembly 3; an iron block 304, embedded and installed at a position on the rotating rod 302 close to the electromagnet 303; and a clamping assembly for clamping and fixing the chromatography column body 1, installed at one end of the rotating rod 302 away from the iron block 304.

[0024] The lifting assembly 3 is an electric telescopic rod.

[0025] The clamping assembly includes a clamping seat 4, a bidirectional lead screw 401, and clamping plates 402. The clamping seat 4 is detachably connected to the rotating rod 302 by threads. A slot is provided on one side of the clamping seat 4 away from the rotating rod 302. The bidirectional lead screw 401 is rotatably connected in the slot. The clamping plates 402 are symmetrically slidably connected in the slot and are threadedly connected to the bidirectional lead screw 401. A rotating handle is rotatably connected to one side of the clamping seat 4, and the rotating handle is fixedly connected to one end of the bidirectional lead screw 401. Rubber pads 403 are fixedly connected to the adjacent sides of the two clamping plates 402.

[0026] When an experimenter needs to perform a chromatography experiment, the storage box 2 can be placed on the workbench at this time. Then, the cover plate 201 can be opened. Then, the lifting assembly 3 can be rotated to make the lifting assembly 3 in a vertical state. Then, the top of the lifting assembly 3 can be raised to a specified position. Then, the clamping assembly and the chromatography column body 1 stored in the storage box 2 can be taken out. Then, the cover plate 201 can be covered. Then, the lifting assembly 3 will be stably in a vertical state under the restriction of the cover plate 201. Then, the rotating rod 302 can be rotated, and the electromagnet 303 can be energized. Then, the electromagnet 303 will limit and fix the rotating rod 302 in cooperation with the iron block 304, so that the rotating rod 302 and the storage box 2 are in a parallel state. Then, the clamping seat 4 can be installed on the end of the rotating rod 302 by threads. Then, the chromatography column body 1 can be placed vertically between the two clamping plates 402. Then, the bidirectional lead screw 401 can be rotated by rotating the rotating handle, so that the bidirectional lead screw 401 drives the two clamping plates 402 to approach each other until the two clamping plates 402 are closely attached to the outer wall of the chromatography column body 1, thereby completing the clamping and fixing of the chromatography column body 1. Then, the experimenter can separate and purify various types of compounds through the chromatography column body 1.

[0027] When the chromatography work is completed, the two-way lead screw 401 can be rotated in the reverse direction at this time to make the two clamping plates 402 move away from each other, and then the chromatography column body 1 can be removed. Then, the clamping seat 4 is separated from the rotating rod 302, and then the electromagnet 303 is powered off. Thus, the rotating rod 302 can be rotated, and then the lifting assembly 3 is controlled to retract. After retracting to the initial position, the cover plate 201 is opened, and the lifting assembly 3 is rotated to fold and store the lifting assembly 3 and the rotating rod 302 into the storage box 2. Then, the clamping assembly and the chromatography column body 1 are placed back into the storage box 2. Finally, the cover plate 201 is covered, and the storage of the lifting assembly 3, the rotating rod 302, the clamping assembly, and the chromatography column body 1 can be completed. By storing the lifting assembly 3, the rotating rod 302, the clamping assembly, and the chromatography column body 1 into the storage box 2, not only can it play a protective effect on them, but also the occupied space of the device can be reduced, which is convenient for storage and placement.

[0028] Embodiment 2:

[0029] Referring to Figures 1 - 4 , a pressure column chromatography device, which is basically the same as Embodiment 1. Further: A fixing ring 301 for making the rotating rod 302 parallel to the lifting assembly 3 after folding is fixedly connected to the top end of the lifting assembly 3. The upper surface of the fixing ring 301 is flush with the upper surface of the electromagnet 303. When the chromatography experiment is completed and the lifting assembly 3 and the rotating rod 302 need to be folded and stored into the storage box 2, the fixing ring 301 can make the rotating rod 302 parallel to the lifting assembly 3 after folding, so that the rotating rod 302 can be stably located in the storage box 2 after completion of storage.

[0030] Two groups of first magnetic strips 203 are symmetrically embedded and installed at the opening end of the storage box 2, and a second magnetic strip 204 attracted to the first magnetic strip 203 is embedded and installed on the cover plate 201. A lifting handle 205 is fixedly installed on one side of the storage box 2. Through the cooperation of the first magnetic strip 203 and the second magnetic strip 204, when the lifting assembly 3, the rotating rod 302, and the clamping assembly are stored in the storage box 2 and the cover plate 201 is covered, the stability of the cover plate 201 covering the storage box 2 can be improved, so that it is convenient for the staff to carry the device through the lifting handle 205.

[0031] Rubber legs 202 are fixedly connected to the four corners at the bottom of the storage box 2. Through the arrangement of the rubber legs 202, when the device is placed on the workbench for use, the stability of the device on the workbench can be improved.

[0032] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
