Description

Technical Field

[0001] The utility model relates to the technical field of chromatographic analysis in the petrochemical industry, in particular to an automatic component developing device for thin-layer chromatography. Background Art

[0002] The analysis of rock soluble organic matter and crude oil group components is of great significance for evaluating oil and gas resources and understanding the mechanisms of oil and gas generation and migration. The analysis of four components (saturated hydrocarbons, aromatics, resins, asphaltenes) is one of the commonly used experimental methods. This method relies on the rod thin-layer chromatography technique to separate and identify different components in the sample through a silica gel chromatography rod.

[0003] However, there are many challenges in the existing experimental process. First of all, the whole analysis process includes up to 11 precise operation steps, from sample preparation to final data scanning and calculation, with a total time consumption of up to 1.5 hours. This not only requires experimenters to have a high degree of professional skills and rich operation experience, but also poses a great test to their physical strength and energy. During the experiment, the development height of the solvent needs to be observed manually at each step, and the rod rack needs to be taken and transferred in a timely manner. These repeated and cumbersome operations not only increase the work intensity of the personnel, but also may introduce operation errors.

[0004] Due to the high dependence on manual operation in the experimental process, subtle operation differences or mistakes may have a significant impact on the accuracy and repeatability of the experimental results. This uncertainty not only reduces the reliability of the experimental data, but also misleads the subsequent oil and gas resource evaluation and development strategy formulation. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an automatic component developing device for thin-layer chromatography, which simplifies the experimental process and improves the efficiency and accuracy of the experiment.

[0006] To solve the above technical problem, the technical solution of the utility model is as follows:

[0007] An automatic component developing device for thin-layer chromatography, comprising:

[0008] A base;

[0009] A slide support seat, arranged on the base;

[0011] A control unit, electrically connected to one end of the double-axis cross slide, and the double-axis cross slide receives the control signal of the control unit for automatic operation;

[0012] A linear guide rail slider, slidably installed on the double-axis cross slide;

[0013] The rod holder support platform is connected to the double-axis cross slide through the linear guide rail slider and moves with the double-axis cross slide.

[0014] The rod holder is mounted on the rod holder support platform, and pre-installed silica gel chromatography rods are provided on the rod holder.

[0015] The constant humidity cylinder is arranged on the base to perform constant humidity treatment on the silica gel chromatography rods on the rod holder.

[0016] The chromatography cylinder is arranged on the base and is connected to the constant humidity cylinder.

[0017] Furthermore, there are two slide support seats, which are arranged at both ends of the base.

[0018] Furthermore, the double-axis cross slide includes:

[0019] The horizontal slide is placed on the slide support seat, and a first electrical interface is provided on one side of the slide, which is connected to the control part.

[0020] The linear guide rail is slidably connected to the horizontal slide, and a second electrical interface is provided on one side of the linear guide rail, which is connected to the control part, driving the rod holder support platform on the linear guide rail slider to move in the vertical direction.

[0021] Furthermore, the rod holder support platform includes:

[0022] The support platform fixed vertical plate is fixed on the linear guide rail slider;

[0023] The support platform tray is fixed on the support platform fixed vertical plate, and the rod holder is placed on the support platform tray;

[0024] The bottom baffle of the support platform is connected to the support platform tray and stably fixes the rod holder on the support platform tray;

[0025] The rod holder guide groove is installed on the support platform fixed vertical plate, and the rod holder moves along a predetermined track.

[0026] Furthermore, there are 3 chromatography cylinders, which are connected to the constant humidity cylinder and arranged on the base.

[0027] Furthermore, the constant humidity cylinder and the chromatography cylinder are provided with notches having the same size as the rod holder at the top, so that the rod holder can enter the constant humidity cylinder and the chromatography cylinder for constant humidity and chromatography treatment.

[0028] The above solution of the present utility model has at least the following beneficial effects:

[0029] Through the electrical connection between the control unit and the two-axis cross slide, the device can achieve efficient automated operation. This automation reduces human intervention, improves work efficiency, and ensures the consistency and accuracy of the experimental process. The two-axis cross slide can move precisely along two axes, and together with the linear guide slider (5), it provides precise positioning capabilities for the rod holder platform and the rod holder. The design of the linear guide slider allows the rod holder platform to move flexibly, enabling the device to adapt to silica gel chromatography rods of different sizes and configurations. In addition, this design also facilitates future possible function expansion.

[0030] The device integrates experimental steps such as air drying, constant humidity treatment, and chromatographic development in one system, eliminating the need to transfer samples between different devices. This simplifies the experimental process and reduces the potential risks of errors and contamination.

[0031] Due to the high degree of integration of the experimental process, the device occupies relatively little space, helping to save valuable laboratory space. At the same time, reducing the transfer between devices and manual operations also saves time and human resources. The constant humidity cylinder provides a constant humidity environment for the silica gel chromatography rod, helping to ensure the stability and reliability of the experimental results. The connection design between the chromatographic cylinder and the constant humidity cylinder also helps to maintain the coherence and consistency of the experimental conditions. The automated and integrated design of the device makes the experimental process easier to monitor. Description of the Drawings

Detailed Description of the Embodiment

[0037] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0038] As Figures 1 to 4 shown, an embodiment of the present utility model provides an automatic component development device for thin-layer chromatography, comprising:

[0039] Base 1;

[0040] Slide table support 2, disposed on the base 1;

[0041] Double-axis cross slide table, installed on the slide table support 2 and moving along two axial directions;

[0042] Control unit 4, electrically connected to one end of the double-axis cross slide table, and the double-axis cross slide table receives control signals from the control unit 4 for automated operation;

[0043] Linear guide rail slider 5, slidably installed on the double-axis cross slide table;

[0044] Rod rack support 6, connected to the double-axis cross slide table through the linear guide rail slider 5 and moving with the double-axis cross slide table;

[0045] Rod rack 7, mounted on the rod rack support 6, and a pre-installed silica gel chromatography rod is provided on the rod rack 7;

[0046] Constant humidity cylinder 8, disposed on the base 1, for performing constant humidity treatment on the silica gel chromatography rod on the rod rack 7;

[0047] Chromatography cylinder 13, disposed on the base 1 and connected to the constant humidity cylinder 8.

[0048] In the embodiment of the present utility model, the base 1 serves as a stable foundation for the entire device, bearing all the components thereon. The slide support base 2 is installed on the base 1 to provide stable support for the two-axis cross slide. The two-axis cross slide is installed on the slide support base 2 and can move precisely in the X-axis and Y-axis directions. The control unit 4 sends control signals to the two-axis cross slide through electrical connection to command its precise automated operation. The linear guide slider 5 is installed on the two-axis cross slide to ensure smooth and precise sliding. The rod holder support 6 is connected to the two-axis cross slide through the linear guide slider 5 and can move precisely with the slide. The rod holder 7 is mounted on the rod holder support 6 and is pre-installed with silica gel chromatography rods. Under the command of the control unit 4, the two-axis cross slide moves the rod holder 7 to the position of the humidity constant cylinder 8 to perform humidity constant treatment on the silica gel chromatography rods. After the humidity constant treatment is completed, the two-axis cross slide moves the rod holder 7 to the position of the chromatography cylinder 13 again according to the control signal to perform chromatography development operation.

[0049] Through the automated control of the control unit 4, the device can precisely execute the preset experimental steps, reduce the errors caused by manual operation, and improve the accuracy and repeatability of the experiment. The automated operation greatly shortens the experimental cycle and improves work efficiency. Experimental personnel can focus more on data analysis and interpretation rather than cumbersome manual operations. The integrated design of the device saves laboratory space and reduces the human resources and material consumption required during the experiment. The designs of the humidity constant cylinder 8 and the chromatography cylinder 13 ensure the consistency and stability of the experimental conditions, thereby improving the credibility of the experimental results. The flexibility of the two-axis cross slide and the linear guide slider 5 enables the device to adapt to silica gel chromatography rods of different sizes and quantities and provides convenience for possible future function expansion. It reduces the direct contact between experimental personnel and harmful chemicals and improves the safety of experimental operations.

[0050] As Figures 1 to 4 shown, there are two slide support bases 2, which are arranged at both ends of the base 1.

[0051] In the embodiment of the present utility model, at both ends of the base 1, a slide support base 2 is respectively arranged. This design of double support bases provides a more stable and balanced support surface for the two-axis cross slide. The two slide support bases 2 are respectively located at both ends of the base 1, which can effectively disperse the weight of the two-axis cross slide and the equipment mounted thereon, and maintain the stability and balance of the entire device. When the two-axis cross slide moves in the X-axis and Y-axis directions, the slide support bases 2 at both ends can jointly bear the load of the slide, reducing the vibration and deviation caused by the movement. During the experiment, the control unit 4 sends commands to the two-axis cross slide to control its precise movement between the two slide support bases 2. No matter which position the two-axis cross slide moves to, the two slide support bases 2 always provide stable support for it, ensuring that experimental operations (such as drying, humidity constant treatment, chromatography development, etc.) can be carried out smoothly.

[0052] Two sliding table support seats 2 are respectively arranged at both ends of the base 1, effectively enhancing the stability of the entire device. This design reduces the shaking and vibration of the device during operation, which is beneficial to the accuracy and stability of experimental operations. The design of the double sliding table support seats enables the device to bear a greater load, is suitable for mounting more or heavier silica gel chromatographic rods, thereby improving the load capacity and application range of the device. By arranging support seats at both ends of the base, the weight of the device is evenly distributed, which helps to reduce stress concentration and mechanical wear and extend the service life of the device. The stable support structure helps to ensure the precise positioning of the two-axis cross slide during movement, thereby improving the accuracy and repeatability of the experiment.

[0053] As Figures 1 to 4 shown, the two-axis cross slide includes:

[0054] A transverse slide 3 is placed on the sliding table support seat 2, and a first electrical interface 15 is provided on one side of the slide 3 and is connected to the control unit 4;

[0055] A linear guide rail 14 is slidably connected to the transverse slide 3, and a second electrical interface 16 is provided on one side of the linear guide rail 14 and is connected to the control unit 4, driving the rod holder platform 6 on the linear guide rail slider 5 to move in the vertical direction.

[0056] In the embodiment of the present utility model, the transverse slide 3 is placed on the sliding table support seat 2 and is connected to the control unit 4 through the first electrical interface 15. In this way, the control unit 4 can send control signals to the transverse slide 3. The linear guide rail 14 is slidably connected to the transverse slide 3, and a second electrical interface 16 is provided on one side thereof, which is also connected to the control unit 4. The control unit 4 sends control instructions to the linear guide rail 14 through the second electrical interface 16.

[0057] When the control unit 4 sends an instruction to the transverse slide 3, the transverse slide 3 will move horizontally (in the X-axis direction) on the sliding table support seat 2. At the same time, when the control unit 4 sends an instruction to the linear guide rail 14 through the second electrical interface 16, the linear guide rail 14 will move longitudinally (in the Y-axis direction) on the transverse slide 3. The linear guide rail slider 5 is installed on the linear guide rail 14 and moves with it. The rod holder platform 6 is connected to the linear guide rail 14 through the linear guide rail slider 5. Therefore, when the linear guide rail 14 moves under the instruction of the control unit 4, it will drive the linear guide rail slider 5 and the rod holder platform 6 to move together in the vertical direction (or the Y-axis direction).

[0058] Through the combination of the horizontal slide 3 and the linear guide rail 14, the device achieves precise movement in a two-dimensional plane (X-axis and Y-axis). This facilitates the precise positioning and processing of the silica gel chromatographic rod. Due to the electrical connection between the biaxial cross slide and the control unit 4, all movement operations can be automated through the control unit 4, improving work efficiency and reducing human operation errors. The design of the biaxial cross slide enables the device to flexibly meet different experimental requirements. Whether in the drying, constant humidity treatment, or chromatographic development stage, specific experimental conditions can be met by precisely controlling the movement of the slide.

[0059] This design of biaxial movement also facilitates future possible function expansion. For example, more processing modules can be added, and the movement path of the biaxial cross slide can be adjusted to adapt to these new modules.

[0060] Automated operation reduces the direct contact between experimental personnel and potentially harmful substances, improving the safety of the experiment. At the same time, the simple design of the electrical control interface also makes the maintenance and troubleshooting of the equipment more convenient.

[0061] As Figures 1 to 4 shown, the rod holder support platform 6 includes:

[0062] A support platform fixed vertical plate 9, fixed on the linear guide rail slider 5;

[0063] A support platform support plate 10, fixed on the support platform fixed vertical plate 9, and the rod holder 7 is placed on the support platform support plate 10;

[0064] A support platform bottom baffle 11, connected to the support platform support plate 10, and stably fixing the rod holder 7 on the support platform support plate 10;

[0065] A rod holder guide groove 12, installed on the support platform fixed vertical plate 9, and the rod holder 7 moves along a predetermined trajectory.

[0066] In the embodiment of the present utility model, the support platform fixed vertical plate 9 is fixed on the linear guide rail slider 5, providing a stable support structure for the entire rod holder support platform 6. The support platform support plate 10 is fixed on the support platform fixed vertical plate 9, forming a stable working surface for placing the rod holder 7. When the rod holder 7 is placed on the support platform support plate 10, the support platform bottom baffle 11 plays a fixing role to ensure that the rod holder 7 does not slip or shift during movement or operation. The rod holder guide groove 12 is installed on the support platform fixed vertical plate 9, providing guidance for the movement of the rod holder 7. When the biaxial cross slide moves, the rod holder 7 will move precisely along the predetermined trajectory of the rod holder guide groove 12.

[0067] The combined design of the support platform fixed vertical plate 9 and the support platform support plate 10 ensures the overall stability of the rod holder support platform 6, which can bear the weight of the rod holder 7 and the silica gel chromatographic rod thereon, ensuring the stability of the experimental operation process.

[0068] The bottom baffle 11 of the support platform effectively prevents the rod holder 7 from slipping during movement or operation, improving the safety of experimental operations. The design of the rod holder guide groove 12 enables the rod holder 7 to move precisely along a predetermined trajectory, which is crucial for chromatographic analysis experiments that require precise positioning and repetitive operations.

[0069] The stable support structure and precise movement guidance contribute to improving the efficiency and accuracy of experimental operations, reducing experimental errors caused by equipment instability or inaccurate movement. The reasonable structural design and high-quality material selection enhance the durability of the rod holder support platform 6.

[0070] As Figures 1 to 4 shown, there are 3 chromatography cylinders 13, which are connected to the humidity control cylinder 8 and arranged on the base 1.

[0071] In the embodiment of the present utility model, 3 chromatography cylinders 13 are provided on the base 1, and these chromatography cylinders are connected to the humidity control cylinder 8. Allowing multiple chromatography experiments to be carried out simultaneously within a single experimental cycle, the humidity control cylinder 8 is used to perform humidity control treatment on the silica gel chromatographic rod to maintain the consistency of experimental conditions. After the treatment is completed, the silica gel chromatographic rod can be directly transferred to the chromatography cylinder 13 connected to the humidity control cylinder 8 for chromatographic development, thereby ensuring the continuity and stability of experimental conditions. The experimenter can control the two-axis cross slide through the control unit 4 to accurately place the humidity-controlled silica gel chromatographic rod into any one of the chromatography cylinders 13 for subsequent chromatographic experiments.

[0072] Setting 3 chromatography cylinders 13 allows multiple experiments to be carried out simultaneously or sequential experiments to be carried out within a single cylinder, thus significantly improving the experimental efficiency. Since the chromatography cylinder 13 is directly connected to the humidity control cylinder 8, the humidity and environmental conditions of the silica gel chromatographic rod are maintained during the transfer to the chromatography cylinder, ensuring the consistency and repeatability of experimental conditions. The setting of multiple chromatography cylinders provides greater flexibility, allowing the experimenter to carry out different types of chromatography experiments or tests under different conditions according to needs. Through the integrated design, multiple chromatography cylinders are arranged on the base 1, effectively saving laboratory space. At the same time, the processing capacity of the humidity control cylinder 8 can be utilized more efficiently, reducing resource waste. The centralized layout enables the experimenter to more conveniently monitor and manage the experimental processes in each chromatography cylinder, ensuring the accuracy and reliability of experimental data.

[0073] As Figures 1 to 4 shown, the humidity control cylinder 8 and the chromatography cylinder 13 are provided with notches of the same size as the rod holder 7 at the top, and the rod holder 7 is inserted into the humidity control cylinder 8 and the chromatography cylinder 13 for humidity control and chromatographic treatment.

[0074] In the embodiment of the present utility model, both the top of the humidity-constant cylinder 8 and the chromatographic cylinder 13 are provided with notches that match the size of the rod holder 7. This design allows the rod holder 7 to smoothly enter the interior of the humidity-constant cylinder 8 or the chromatographic cylinder 13 through the notches. When performing humidity-constant or chromatographic treatment, the experimenter can precisely control the position of the rod holder 7 through the two-axis cross slide, align it with the notch, and smoothly place the rod holder 7 into the humidity-constant cylinder 8 or the chromatographic cylinder 13 through the notch. Once the rod holder 7 enters the humidity-constant cylinder 8, the environment inside the humidity-constant cylinder will maintain a constant humidity, performing humidity-constant treatment on the silica gel chromatographic rod. When the rod holder 7 enters the chromatographic cylinder 13, a specific solvent or developing agent inside the chromatographic cylinder will perform chromatographic development on the silica gel chromatographic rod to separate different compounds.

[0075] The notch design matches the size of the rod holder 7, enabling the rod holder 7 to easily and accurately enter the humidity-constant cylinder 8 and the chromatographic cylinder 13, simplifying the experimental operation process. The design of the humidity-constant cylinder 8 ensures that the silica gel chromatographic rod is in a stable humidity environment during the humidity-constant treatment, contributing to improving the accuracy and repeatability of the experiment.

[0076] By precisely controlling the entry and exit of the rod holder 7, the humidity-constant and chromatographic treatments of the silica gel chromatographic rod can be completed quickly, thereby improving the experimental efficiency. The rod holder 7 enters the cylinder through the notch, reducing the direct contact between the experimenter and the environment inside the cylinder, thus reducing the pollution risk. The compatibility between the notch design and the rod holder 7 ensures a smooth transition between different experimental steps, making the entire experimental process more efficient and smooth.

[0077] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
