Description

Technical Field

[0001] The present application relates to the technical field of liquid chromatographs, and in particular to a cleaning device for liquid chromatographs. Background Art

[0002] Liquid chromatography is an instrument that uses the difference in the distribution ratio of a mixture between liquid and solid or between two immiscible liquids to first separate and then analyze and identify the mixture. Liquid chromatography is widely used in chemistry, biochemistry, environmental monitoring, pharmaceuticals, food safety and other fields, and can efficiently separate and analyze various complex mixtures.

[0003] In the prior art, the waste liquid barrel in the liquid chromatograph can collect the generated waste liquid. During long-term use, the waste liquid barrel needs to be cleaned. Currently, the inside of the waste liquid barrel is generally cleaned directly by hand. This cleaning method is inefficient and may not be able to completely cover and clean every corner and surface during the cleaning process, especially there may be hard-to-reach corners or depressions inside the waste liquid barrel. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose a liquid chromatograph cleaning device to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides a liquid chromatograph cleaning device, comprising a bracket, a rotating shaft fixedly penetrated through the inner side of the bracket, a swing arm rotatably connected to the outer surface of the rotating shaft, an upper arm shaft rotatably connected to the top of the swing arm, a support fixedly connected to the outer surface of the upper arm shaft, a waste liquid barrel arranged on the support, and a driving mechanism for repeatedly oscillating the waste liquid barrel arranged on the inner side of the bracket.

[0006] Preferably, the driving mechanism comprises a fixed platform fixedly connected to the bracket, and a platform shaft is fixedly penetrated through the inner side of the fixed platform. The rotating shaft can be rotated by the driving mechanism, and then the waste liquid barrel on the support can be swung back and forth through the upper arm shaft.

[0007] Preferably, an outer surface of the table shaft is rotatably connected to an electric push rod, and an output end of the electric push rod is fixedly connected to a collar.

[0008] Preferably, the inner surface of the collar is rotatably connected to a ring shaft, and the outer surface of the ring shaft is fixedly connected to a connecting frame.

[0009] Preferably, both ends of the connecting frame are fixedly connected to straight rod frames, the bottom of the swing arm is rotatably connected to a lower arm shaft, and the outer surface of the lower arm shaft is rotatably connected to the inner surface of the straight rod frame.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The liquid chromatograph cleaning device can make the waste liquid barrel in the chromatograph constantly swing during the oscillation process through the driving mechanism. This movement forms a complex convection movement inside the clean water. The convection movement helps to evenly distribute the cleaning agent to every corner and surface in the waste liquid barrel, ensuring thorough cleaning and flushing of residual substances. After that, the waste liquid barrel can be cleaned quickly and effectively with simple manual cleaning.

[0012] 2. The liquid chromatograph cleaning device automates and mechanizes the operation of the waste liquid barrel vibration cleaning process. Through the coordinated actions of the electric push rod, connecting frame, straight rod frame and other mechanisms, it can ensure the efficient cleaning process. This automated operation not only reduces the time of manual operation, but also improves the consistency and efficiency of cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-3 A liquid chromatograph cleaning device comprises a bracket 1, a rotating shaft 2 is fixedly penetrated on the inner side of the bracket 1, a swing arm 3 is rotatably connected to the outer surface of the rotating shaft 2, an upper arm shaft 4 is rotatably connected to the top of the swing arm 3, a support 5 is fixedly connected to the outer surface of the upper arm shaft 4, a waste liquid barrel 6 is arranged on the support 5, and a driving mechanism for repeatedly oscillating the waste liquid barrel 6 is arranged on the inner side of the bracket 1.

[0019] Through the above technical solution, during the use of the device, when a large amount of waste liquid is stored in the waste liquid barrel 6 for a long time, the waste liquid barrel 6 needs to be manually cleaned. Before this, the waste liquid barrel 6 can be driven by the driving mechanism to make the waste liquid barrel 6 vibrate repeatedly.

[0020] Specifically, the driving mechanism includes a fixing platform 7 fixedly connected to the bracket 1 , and a platform shaft 8 is fixedly penetrated through the inner side of the fixing platform 7 .

[0021] Through the above technical solution, considering that the electric push rod 9 will produce a certain angle deflection during the process of pushing and pulling the ring 10, the table shaft 8 is designed to facilitate the deflection of the electric push rod 9.

[0022] Specifically, the outer surface of the table shaft 8 is rotatably connected to an electric push rod 9 , and the output end of the electric push rod 9 is fixedly connected to a collar 10 .

[0023] Through the above technical solution, when the electric push rod 9 pushes or pulls the collar 10 , the collar 10 will rotate along the ring axis 11 .

[0024] Specifically, the inner surface of the collar 10 is rotatably connected to the ring shaft 11 , and the outer surface of the ring shaft 11 is fixedly connected to the connecting frame 12 .

[0025] Through the above technical solution, after the connecting frame 12 is pushed and pulled by the electric push rod 9, it will drive the straight rod frame 13 to move synchronously.

[0026] Specifically, both ends of the connecting frame 12 are fixedly connected with the straight rod frame 13 , the bottom of the swing arm 3 is rotatably connected with the lower arm shaft 14 , and the outer surface of the lower arm shaft 14 is rotatably connected to the inner surface of the straight rod frame 13 .

[0027] Through the above technical solution, after the connecting frame 12 moves, it will drive the swing arm 3 through the lower arm shaft 14, so that the swing arm 3 rotates along the rotating shaft 2.

[0028] Working principle: the waste liquid barrel 6 in the liquid chromatograph needs to be cleaned regularly during the long-term storage of waste liquid. Before manually cleaning the waste liquid barrel 6, the waste liquid in the waste liquid barrel 6 is first poured out, and then clean water is injected into the waste liquid barrel 6, and then the electric push rod 9 is turned on to push and pull the ring 10. During this process, the ring 10 will rotate along the ring shaft 11, and the bottom end of the electric push rod 9 will rotate along the table shaft 8 to cooperate with it for angular deflection. In the process of the electric push rod 9 pushing and pulling the connecting frame 12 through the ring shaft 11, the connecting frame 12 will drive the straight rod frame 13 to move synchronously, and the straight rod frame 13 will drive the lower arm shaft 14 to move synchronously during the movement. During this period, the swing arm 3 will rotate along the lower arm shaft 14, that is, the lower arm shaft 14 pushes and pulls the swing arm 3, so that the swing arm 3 rotates back and forth along the rotating shaft 2, and at the same time, the swing arm 3 will move along the top The upper arm shaft 4 rotates and drives the support 5 through the upper arm shaft 4, so that the waste liquid barrel 6 on the support 5 swings back and forth, and finally the waste liquid barrel 6 is in a state of continuous oscillation. The oscillation will cause convection movement inside the clean water. When the waste liquid barrel 6 is vibrated, the clean water in the waste liquid barrel 6 will produce up and down, left and right or surrounding flow due to inertia. This convection movement helps to bring the cleaning agent to every corner and surface in the barrel, thereby flushing and removing residual substances. At the same time, the oscillation will promote the diffusion and dispersion of the solutes in the cleaning agent and the residual substances in the waste liquid barrel 6. This diffusion effect can make the cleaning agent quickly penetrate into every corner of the waste liquid barrel 6, especially the hard-to-reach areas, to ensure that all surfaces are fully cleaned and treated. Finally, with the help of simple manual cleaning, the waste liquid barrel 6 can be cleaned quickly and effectively.
