Description

Technical Field

[0001] This utility model relates to the field of chromatography column technology, and in particular to an activated carbon chromatography column for removing tert-butyl alkane impurities. Background Technology

[0002] Activated carbon chromatography columns for removing tert-butyl alkane impurities are used to separate different hydrocarbons and optimize product composition analysis. The principle is based on the difference in adsorption capacity of activated carbon for different substances. Activated carbon has a porous structure and a large specific surface area, exhibiting weak adsorption of non-polar or weakly polar substances and strong adsorption of polar substances. When a solution containing dialkane impurities passes through the chromatography column, the impurities are retained due to strong adsorption by the activated carbon, while the dialkane elutes quickly, achieving separation.

[0003] Since the outer surface of the chromatography column is made of glass or plexiglass, when the column is not in use, collisions to the outside of the column can cause damage to the glass or plexiglass components. In addition, since chromatography often takes a long time, collisions and vibrations during the process can affect the chromatography results. Based on this, the present invention is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an activated carbon chromatography column for removing tert-butyl alkane impurities that can overcome or at least partially solve the above problems.

[0007] Preferably, the protective bracket is threadedly connected to an adjusting bolt, which is rotatably connected to the top block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Refer to Figures 1-5 An activated carbon chromatography column for removing tert-butyl alkane impurities includes a chromatography column body 1, and further includes: a first support frame 11 fixedly connected to the chromatography column body 1, a plurality of transition air bags 24 fixedly connected to the first support frame 11, and a protective sleeve 2 fixedly connected to the other end of the transition air bags 24; a protective bracket 3 for withstanding external impacts, a top block 33 slidably connected to the protective bracket 3, and a compression spring 34 connected between the protective sleeve 2 and the top block 33; when the top block 33 slides, the buffer elasticity of the compression spring 34 changes, and the vibration frequency transmitted by the protective bracket 3 when it is impacted changes.

[0027] In this invention, a protective sleeve 2 and a protective support 3 are respectively provided on the outside of the chromatography column body 1 to protect the chromatography column body 1. When the protective support 3 is impacted and displaced, it will compress the spring 34. The spring 34 buffers the impact force and transmits the impact effect to the protective sleeve 2. After absorbing the impact, the protective sleeve 2 transmits the impact force to the transition air bag 24. After secondary buffering by the transition air bag 24, the remaining impact force is transmitted to the chromatography column body 1. This can maximize the buffering of the impact received from the outside and avoid damage to the chromatography column body 1 and the impact on the chromatography effect.

[0028] By sliding the top block 33, the distance between the top block 33 and the protective sleeve 2 can be changed, thereby changing the compression degree of the compression spring 34 before it is impacted. When the top block 33 is close to the protective support 3, the compression spring 34 is in a relatively relaxed state. At this time, when the protective support 3 is slightly impacted, the compression spring 34 will undergo a large deformation. This state is suitable for protecting the chromatography column body 1, but because the amplitude of shaking is large, it is not suitable for use during chromatography. Large shaking can easily affect the chromatography effect. When the top block 33 moves towards the protective sleeve 2, the initial state of the compression spring 34 is in a tight compressed state. At this time, if the protective support 3 is impacted by the outside, it will produce a relatively small displacement. It can play a certain buffering role and reduce the vibration generated when impacted, which is more suitable for use during chromatography.

[0029] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but further: the protective bracket 3 is connected to the adjusting bolt 32 by a thread, the adjusting bolt 32 is rotatably connected to the top block 33, the protective bracket 3 is provided with a protective railing 31, the protective sleeve 2 is provided with an observation hole 21, the protective sleeve 2 is fixedly connected to the second support frame 22, the second support frame 22 is fixedly connected to the outer support ring 23, the outer support ring 23 is fixedly connected to the buffer airbag 4, the buffer airbag 4 is fixedly connected to the buffer spring 41, the buffer airbag 4 is provided with an air inlet 42 and an air outlet 43, both the air inlet 42 and the air outlet 43 are provided with a one-way valve, the bottom of the first support frame 11 is fixedly connected to the material platform 12, when the outer support ring 23 is offset, the material platform 12 comes into contact with the buffer airbag 4, and the bottom of the material platform 12 is fixedly connected to a layer of rubber anti-slip pad.

[0030] In this utility model, by fixing a second support frame 22 and an external support ring 23 on the protective sleeve 2, the protective sleeve 2 can be supported and fixed independently, and the vibration generated by the protective sleeve 2 can be corrected independently.

[0031] A buffer airbag 4 is fixedly connected to the outer support ring 23. There is a certain gap between the buffer airbag 4 and the material platform 12. When the vibration amplitude of the protective sleeve 2 is too large, it will drive the outer support ring 23 to move. At this time, the buffer airbag 4 will collide with the material platform 12. After the collision, the air inside the buffer airbag 4 is discharged through the air outlet 43 and reset under the action of the buffer spring 41. During the reset process, the external gas enters the buffer airbag 4 through the air inlet 42, thereby achieving a further buffering effect. At the same time, the diameter of the air outlet 43 is larger than the diameter of the air inlet 42, so that the buffer airbag 4 can quickly discharge the internal gas when it collides to reduce the intensity of the collision. The reset speed is slowed down to a certain extent to avoid the reset speed being too fast when multiple collisions occur in a short period of time, so that each collision will produce a strong impact. The buffer spring 41 is used to help the buffer airbag 4 reset.

[0032] The position of the top block 33 can be adjusted by rotating the adjusting bolt 32, thereby adjusting the initial compression strength of the compression spring 34 according to different usage requirements.

[0033] By setting up a protective railing 31 and adjusting the observation hole 21, the user can observe the liquid level of the chromatography column body 1. The part of the first support frame 11 that connects to the chromatography column body 1 is made of transparent material.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
