Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, and in particular to a chromatography column device. Background Technology

[0002] Taking a high-pressure chromatography column with an inner diameter of 1200 mm as an example, the weight of the column base reaches 2500 kg, and the number of screws that need to be fixed between the column base and the column tube is very large. Currently, during assembly, it is generally done by manually operating a forklift to slowly push and position the column. This requires repeated adjustments to the forklift to ensure alignment, which is time-consuming, labor-intensive, and poses safety hazards (such as deformation of the fork teeth during the lifting process and potential tilting of the two fork tooth surfaces).

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figures 1 to 2 This illustration shows an embodiment of the chromatography column apparatus of the present invention. The chromatography column apparatus of this embodiment includes a support 1, a column tube 2 disposed on the support 1, a transfer trolley 3, and a bottom cover 4 detachably connected to the column tube 2 (for example, connected by a plurality of threaded fasteners arranged in a circumferential direction). It also includes a bracket 5, which is provided with a trolley positioning area 51. The support 1 is provided with a lifting drive assembly 6 for driving the bracket 5 to raise and lower the bottom cover 4 and the transfer trolley 3, and a lifting guide assembly 7 for providing guidance for the bracket 5.

[0025] In this embodiment of the chromatography column apparatus, when the bottom cover 4 needs to be assembled, the bottom cover 4 is transported using a transfer trolley 3. Once the transfer trolley 3 enters the trolley positioning area 51 of the support 5, the bottom cover 4 is positioned in the horizontal plane. Then, the lifting drive assembly 6 drives the support 5 to rise, and the bottom cover 4 and the transfer trolley 3 rise synchronously with the support 5 until the bottom cover 4 is docked and assembled with the column tube 2. The lifting guide assembly 7 provides guidance for the lifting movement of the support 5, preventing the support 5 from shifting and reducing frictional resistance. The structure is simple, reliable, and safe, which helps improve assembly efficiency. Preferably, the bottom cover 4 and the transfer trolley 3 are also connected as a single unit using threaded fasteners to prevent the bottom cover 4 from moving relative to the transfer trolley 3, thereby ensuring accurate positioning of the bottom cover 4 on the transfer trolley 3. If necessary, the connection between the transfer trolley 3 and the bottom cover 4 can be disconnected to separate the transfer trolley 3 and the bottom cover 4.

[0026] Furthermore, in this embodiment, the trolley positioning area 51 is a U-shaped area, which facilitates the transfer trolley 3 to enter the trolley positioning area 51 and simultaneously completes the positioning in all directions. The structure is simple and effective.

[0027] Furthermore, in this embodiment, positioning guide rails 52 are provided on both sides of the trolley positioning area 51, and positioning guide wheels 31 are provided on both sides of the transfer trolley 3 to cooperate with the positioning guide rails 52. Through the cooperation between the positioning guide wheels 31 and the positioning guide rails 52, the gap between the left and right sides of the transfer trolley 3 and the trolley positioning area 51 can be further reduced, improving positioning accuracy. Moreover, the frictional resistance is low, so it will not hinder the transfer trolley 3 from entering and exiting the trolley positioning area 51, resulting in a reasonable structure. Preferably, multiple positioning guide wheels 31 are provided along the length of the positioning guide rails 52, which is beneficial for further improving the guiding effect.

[0028] Furthermore, in this embodiment, a guide portion 53 is provided at one end of the positioning guide rail 52 corresponding to the opening of the trolley positioning area 51. The closer the guide portion 52 is to the positioning guide rail 52, the smaller the width between the two guide portions 53. Setting guide portions 53 with gradually decreasing width is beneficial for the transfer trolley 3 to smoothly enter the trolley positioning area 51, reducing the difficulty of operation for the operator.

[0029] Furthermore, in this embodiment, the lifting drive assembly 6 includes a lifting drive component 61, which is located on both sides of the trolley positioning area 51. It has good symmetry and is conducive to achieving synchronous and stable lifting of the bracket 5, the bottom cover 4 and the transfer trolley 3 as a whole.

[0030] Preferably, the lifting drive component 61 is a pneumatic cylinder or a hydraulic cylinder, which has a simple and reliable structure.

[0031] Furthermore, in this embodiment, the lifting guide assembly 7 includes a lifting guide rail 71, which is disposed on both sides of the trolley positioning area 51. The bracket 5 is provided with a slider 54 that cooperates with the lifting guide rail 71. Through the cooperation of the lifting guide rail 71 and the slider 54, the frictional resistance of the bracket 5 in lifting can be reduced, the synchronicity of the lifting of the bracket 5 at various points can be improved, and the bracket 5 can be prevented from tilting or deviating, thus ensuring good reliability.

[0032] Preferably, two rows of lifting guide rails 71 are provided on each of the left and right sides, and the lifting drive component 61 is located between the two rows of lifting guide rails 71 on the same side, which has good symmetry and balance.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
