Description

Technical Field

[0001] The invention relates to the technical field of capillary tube manufacturing, in particular to a flexible quartz glass multi-core capillary tube and a processing and drawing device thereof. Background Art

[0002] Chromatographic technology originated in the early 20th century and developed rapidly by the middle of the 20th century. In particular, Mr. Dandeneau invented the fused silica flexible capillary chromatographic column in 1979, which ushered in a new era of capillary chromatographic analysis and separation technology. It has become the most important and advanced means for contemporary precision chemical analysis and separation of various substances such as amino acids and proteins. It is widely used in petrochemical industry, food industry, wine production, production of various beverages such as carbonated beverages, synthesis of various organic compounds, physiological and biochemical analysis and research, pharmaceuticals, environmental protection, food safety, production of detergents and cosmetics, life science research, and space exploration. Therefore, capillary chromatographic column analysis and separation technology are closely related to the survival and development of contemporary human civilization.

[0003] Flexible quartz glass capillary chromatography technology has become the most important and most accurate technical means for contemporary organic matter analysis, testing, and separation of various proteins and amino acids. However, contemporary flexible quartz glass capillary chromatography column analysis and separation technology still has a major flaw, that is, the chromatographic column manufacturing process and the work and operation process of chromatographic analysis and separation take a very long time. Usually, it takes at least several hours or more than ten hours to analyze and separate a sample, and it takes dozens of hours or even longer. This greatly limits the application scope of capillary chromatography analysis and separation and restricts the development of this technology. In response to this problem, scientists from all over the world have conducted in-depth research and introduced the concept of "porous capillary" more than ten years ago. The same volume of porous structure greatly increases the internal surface area of the capillary. In theory, the increase in the internal surface area of the capillary is equal to the same time. As the number of plates passed increases, the efficiency and rate of separation increase accordingly. The greatly increased efficiency and rate of separation will of course greatly shorten the working time of chromatographic separation and analysis. However, since each capillary chromatographic column still requires a certain length, such as tens of centimeters or several meters, the capillaries made into chromatographic columns need to be coiled into a spiral shape, otherwise they cannot be installed in the chromatograph. Each small hole in the porous structure occupies a different position on the cross-section of the capillary. The path length of the mobile phase entering the small holes at different positions to reach the output end is different. The path length is different, and the diameter of each hole cannot be completely consistent. The resistance to the flow of the fluid in the branch pipe is different. However, the injection conditions of the mobile phase entering each small hole are the same. Therefore, the time for the mobile phase in each small hole to reach the output end will also be different, resulting in a significant broadening of the resulting pulse. Summary of the Invention

[0016] (3) Beneficial effects

[0017] The present invention provides a flexible quartz glass multi-core capillary and a processing and drawing device thereof. It has the following beneficial effects:

[0018] (1) The flexible quartz glass multi-core capillary and the processing and drawing equipment thereof, when the motor is started, the transmission belt drives the rotating ring to rotate, and as the rotating ring rotates, the rotating frame starts to rotate, and the mounting tube is driven to rotate by the rotating frame. The rotation of the mounting tube drives the No. 1 connecting ring and the No. 2 connecting ring to rotate, and then the processing ring inside the No. 1 connecting ring starts to rotate. At this time, the stabilizing seat heats the outer surface of the main tube through the heating tube to soften it at high temperature, that is, the outer surface of the main tube is in a softened state when it enters the processing ring. At this time, the outer surface of the main tube is spiraled by the protrusions on the inner surface of the rotating processing ring, and then the main tube is automatically spiraled when the capillary is drawn, which greatly improves the production speed of the capillary tube, simplifies the production steps of the capillary tube, and greatly reduces the production cost of the enterprise.

[0019] (2) The flexible quartz glass multi-core capillary and its processing and drawing equipment, after the main pipe is spiral-formed, it will then enter the No. 2 connecting ring. At this time, the coating layer paint is introduced into the No. 2 connecting ring through the feed pipe, and finally discharged through the nozzle on the gathering ring to be sprayed on the outer surface of the main pipe to complete the production of the coating layer, and the excess paint is recovered through the discharge pipe in the top ring on the No. 1 connecting ring, thereby achieving automatic completion of the coating layer production during capillary drawing and also recycling of excess paint, greatly reducing paint waste, further reducing enterprise costs, and greatly reducing the possibility of pollution. The capillary with the coating layer then enters the lower installation tube, and the coating layer is cured by the rotating ultraviolet light board at this time, thereby achieving automatic curing of the coating layer after the coating layer is sprayed, greatly reducing the difficulty of using the equipment, improving the degree of automation of the equipment, and at the same time greatly improving the continuity of capillary drawing, avoiding the problem of needing to make the coating layer separately later.

[0020] (3) The flexible quartz glass multi-core capillary and its processing and drawing equipment, when the solidified capillary enters the auxiliary ring, cold air is introduced into the air duct of the auxiliary ring through the air inlet pipe. After entering the air duct, the cold air blows on the outer surface of the main pipe through the top of the auxiliary ring, thereby completing the initial cooling of the capillary, avoiding the problem that the outer surface of the capillary is too soft and is deformed during winding, affecting the quality of the capillary. After entering the air duct, the cold air enters the rotating frame through the dispersion holes at the bottom of the rotating frame. The cold air is dispersed and softened by the inclined spiral rotating frame and the dispersion holes, thereby achieving a significant increase in the moving speed of the cold air in the auxiliary ring when cooling the capillary by the cold air, and limiting the cold air to flow out only through the bottom of the auxiliary ring, thereby significantly improving the cooling effect on the capillary, avoiding the problem of airflow counterattack and reducing the cooling effect of the commonly used annular cooling nozzle. At the same time, the uniformity of the cold air in the auxiliary ring can be greatly improved by homogenizing and dispersing the cold air through the rotating frame, further improving the cooling effect on the capillary.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] First embodiment: Figure 1 As shown, the present invention provides a technical solution: a flexible quartz glass multi-core capillary tube, comprising a main tube 1, an inner core 2 fixedly connected to the inner surface of the main tube 1, four inner cores 2 are arranged at fixed intervals around the central axis of the main tube, and the four inner cores 2 are combined into a stamen shape, the outer surface of the main tube 1 is provided with a spiral groove, and the outer surface of the main tube 1 is provided with a coating layer.

[0036] The multi-core capillary uses the basic concept of the multi-porous capillary, but the structure is different from the multi-porous. The sum of the inner and outer wall areas of the four inner cores 2 is 2.6 times the inner wall area of the traditional capillary with the same column volume. Therefore, the inner surface area of the multi-core capillary with the same column volume is 3.5 times the inner surface area of the traditional single-pore capillary. According to the principles of chromatography analysis and separation technology, the interaction between the stationary phase and the mobile phase of the working substance (gaseous or liquid) injected into the chromatographic column, and the difference in the distribution of each component per unit time between the two phases cause the forward migration speed of each component to change. The different migration speeds force the components to gradually separate during the flow process. When the distribution of a component between the two phases reaches equilibrium, the component is separated from the working substance. The separation process can be regarded as a function of time or distance. In the basic equation of chromatography, the retention time tR=tM(1+K) is related to the phase equilibrium parameters, distribution coefficient, The capacity factor is related to the column length, the flow rate of the mobile phase, and the volume of the two phases. The thermodynamic factor partition coefficient K = Cs / Cm is the determining factor. The so-called retention time is the time from the sample entering the chromatographic column to the time a component is separated and reaches the end of the column and is detected by the detector. In the formula, Cs is the mass concentration of the component in the stationary phase; Cm is the concentration of the component in the mobile phase. Under the same environment and working conditions, the phase partition coefficient of each component is determined by the material properties of the component itself. Although the mass concentration per unit area of the stationary phase on the inner wall of a multi-core capillary column is basically the same as that of a traditional chromatographic column, the significant increase in the internal surface area makes the difference in the integrated total content of different components in the stationary phase increase exponentially, and the column separation is significantly improved. Separation is a key parameter of a chromatographic column. The higher the separation, the stronger the ability to distinguish between components and the more obvious the resolution. The basic equation for separation is:

[0037]

[0038] Where: neff is the effective plate number; α is the selectivity factor (or distribution ratio). From the basic equation of separation, we can see that the separation R is proportional to the square root of the plate number. Increasing the plate number can improve the separation. According to the plate theory, the internal surface area per unit capillary length is the determining factor for converting the theoretical plate number of the capillary. The larger the internal surface area per unit length of the capillary, the higher the theoretical plate number. Compared with traditional flexible fused silica capillaries, flexible quartz glass multi-core capillaries greatly increase the internal surface area of the capillary while maintaining the same column volume, greatly increasing the theoretical plate number of the chromatographic column, thereby greatly improving the separation of the chromatographic column. Figure 10 As shown:

[0039] The separation degree of flexible quartz glass multi-core capillary chromatographic column is much higher than that of traditional single-hole quartz glass capillary chromatographic column. During the chromatographic separation process, the more times the components reach distribution equilibrium between the two phases during the process of passing through the capillary chromatographic column, the better the separation effect and the higher the column efficiency. The significance of the equilibrium number is to force the total amount of the separated components contained in the working material mixture to reach equilibrium between the two phases. The flexible quartz glass multi-core capillary greatly increases the internal surface area of the chromatographic column, so that each component in the working material of the chromatographic column can reach equilibrium in the two phases per unit time. The total amount of substances that reach equilibrium between the two phases is greatly increased, thus greatly shortening the time for the total amount of each component to reach equilibrium between the two phases, and greatly shortening the time for chromatographic separation (analysis) of each sample. According to the rate theory of chromatography, the broadening of the chromatographic peak is mainly caused by the different migration rates of the component molecules in the column. The migration rate of the component molecules is mainly controlled by three kinetic factors, namely: eddy diffusion, molecular diffusion and mass transfer resistance. The four C-shaped cores of the flexible quartz glass multi-core capillary transform the capillary cavity into 8. The migration of the working medium in the central channel of the capillary is the dominant flow of molecular diffusion, and the migration of the working medium in the 8 branch channels surrounding it is integrated with the dominant flow from beginning to end. The rate of two-phase exchange and the speed of working medium migration in each branch channel are all controlled by the dominant flow. There is no difference in the molecular migration rate of each component in each channel. Therefore, the peak pulse in the chromatographic band will not be broadened. The flexible quartz glass multi-core capillary is a spiral tube structure along the axis, which eliminates the difference in the length of the inner and outer ring channels when the chromatographic column is bent, and effectively eliminates the chromatographic peak broadening caused by the complex path. The spiral tube structure forces the fluid to rotate forward around the axis in the multi-core capillary chromatographic column. The rotating centrifugal force forces the vortex generated by the friction of the movement to change direction. A deflection angle appears between the vortex resistance vector and the fluid movement vector, which weakens the influence of vortex diffusion, reduces the mass transfer resistance of the flow, and prevents laminar flow of the chromatographic column fluid, accelerates the equilibrium of the two phases, and shortens the separation time of the working medium components. The experimental results show that Figure 11 and Figure 12 .

[0040] Second embodiment: Figures 2 to 9 As shown, the present invention provides a technical solution: a processing and drawing device for a flexible quartz glass multi-core capillary, comprising a bottom plate 3, a through-groove 4 being formed through the middle upper surface of the bottom plate 3, and further comprising:

[0041] A drawing mechanism 5 is fixedly mounted on the upper surface of the base plate 3;

[0042] The reinforcing mechanism 6 is fixedly mounted on the drawing mechanism 5;

[0043] The drawing mechanism 5 includes a rotating disk 51, which is rotatably connected to the upper surface of the base plate 3. The input end of the rotating disk 51 is rotatably connected to a motor 52, and the motor 52 is fixedly installed on the upper surface of the base plate 3. The middle bottom surface of the rotating disk 51 is fixedly connected to a winding roller 53, and the winding roller 53 is arranged below the base plate 3.

[0044] A rotating ring 54 is rotatably connected to the middle upper surface of the base plate 3, and a transmission belt 55 is rotatably connected to the outer surface of the rotating ring 54. The end of the transmission belt 55 away from the rotating ring 54 is rotatably connected to the rotating disk 51. A connecting rod 56 is fixedly connected to the middle upper surface of the base plate 3, and a fixing frame 57 is fixedly connected to the top of the connecting rod 56.

[0045] A stabilizing seat 58 is fixedly connected to the fixing frame 57, a feed hole 59 is penetrated through the middle upper surface of the stabilizing seat 58, a fixing ring 510 is fixedly connected to the outer surface of the stabilizing seat 58, a heating tube 511 is fixedly installed inside the fixing ring 510, a connecting tube 512 is fixedly connected to the bottom of the stabilizing seat 58, and a connecting ring 513 is rotatably connected to the bottom outer surface of the connecting tube 512.

[0046] The top inner surface of the No. 1 connecting ring 513 is fixedly connected to a processing ring 514 . The top inner surface of the processing ring 514 is fixedly connected to a protrusion 515 . Six protrusions 515 are arranged at fixed intervals around the central axis of the processing ring 514 .

[0047] The bottom of the No. 1 connecting ring 513 is fixedly connected to the No. 2 connecting ring 516, the inner surface of the No. 2 connecting ring 516 is fixedly connected to the gathering ring 517, the inner surface of the gathering ring 517 is fixedly connected to the nozzle 518, the bottom surface of the gathering ring 517 is fixedly connected to the mounting tube 519, and the inner surface of the mounting tube 519 is symmetrically fixedly connected to the purple light board 520.

[0048] The outer surface of the No. 2 connecting ring 516 is penetrated by a bottom ring 521 for rotational connection, the outer surface of the bottom ring 521 is penetrated by a feed pipe 522 for fixed connection, the outer surface of the No. 1 connecting ring 513 is penetrated by a top ring 523 for rotational connection, the outer surface of the top ring 523 is penetrated by a discharge pipe 524 for fixed connection, the top ring 523 is fixedly connected to the connecting rod 56 through a connecting rod, and the bottom ring 521 is fixedly connected to the connecting rod 56 through a connecting rod.

[0049] The third embodiment: Figures 2 to 9 As shown, the reinforcing mechanism 6 includes a fixed tube 61, which is fixedly connected to the penetrating groove 4 of the base plate 3. The bottom of the fixed tube 61 is fixedly connected to a guide ring 62, which is arranged below the base plate 3. The top of the fixed tube 61 is fixedly connected to an auxiliary ring 63, and an air duct 64 is opened through the interior of the auxiliary ring 63. The top of the air duct 64 is inclined, and the bottom outer surface of the auxiliary ring 63 is fixedly connected to an air inlet pipe 65.

[0050] The top of the rotating ring 54 is fixedly connected to a rotating frame 66 , which is rotatably connected in the air duct 64 . The middle of the rotating frame 66 is inclined, and a dispersion hole 67 is opened through the bottom of the rotating frame 66 .

[0051] During operation, the preliminarily manufactured main pipe 1 together with its inner core 2 is introduced through the feed hole 59 on the stabilizing seat 58, and is led out through the penetrating groove 4 on the bottom plate 3 and wound on the winding roller 53, and the motor 52 is started. As the motor 52 is started, the capillary is gradually wound on the winding roller 53 and waits for cooling to complete the drawing of the capillary. When the motor 52 is started, the rotating ring 54 is driven to rotate through the transmission belt 55. As the rotating ring 54 rotates, the rotating frame 66 starts to rotate, and the mounting tube 519 is driven to rotate through the rotating frame 66. The rotation of the mounting tube 519 drives the No. 1 connecting ring 513 and the No. 2 connecting ring 516 to rotate, thereby causing the processing ring 514 in the No. 1 connecting ring 513 to start rotating. At this time, the stabilizing seat 58 is heated The tube 511 is heated to soften the outer surface of the main tube 1 at high temperature, that is, the outer surface of the main tube 1 is in a softened state when entering the processing ring 514. At this time, the outer surface of the main tube 1 is spiraled by the protrusion 515 on the inner surface of the rotating processing ring 514, thereby automatically spiraling the main tube 1 during the capillary drawing, greatly improving the production speed of the capillary, simplifying the production steps of the capillary, and greatly reducing the production cost of the enterprise. After the spiraling treatment, the main tube 1 will then enter the second connecting ring 516. At this time, the coating layer paint is introduced into the second connecting ring 516 through the feeding pipe 522, and finally guided out through the nozzle 518 on the gathering ring 517 and sprayed on the outer surface of the main tube 1 to complete the production of the coating layer, and the excess paint is discarded. The recycling is completed through the discharge pipe 524 in the top ring 523 on the No. 1 connecting ring 513, so that the coating layer can be automatically completed when the capillary is drawn, and the excess paint can also be recycled, which greatly reduces the waste of paint, further reduces the cost of the enterprise, and greatly reduces the possibility of pollution. The capillary made by the coating layer then enters the lower installation tube 519. At this time, the coating layer is cured by the rotating ultraviolet light board 520, so that the coating layer is automatically cured after the coating is sprayed, which greatly reduces the difficulty of using the equipment, improves the degree of automation of the equipment, and greatly improves the continuity of capillary drawing, avoiding the problem of needing to make a separate coating layer later. When the cured capillary enters the auxiliary ring 63, the cold air is introduced into the air duct 64 of the auxiliary ring 63 through the air inlet pipe 65. After entering the air duct 64, the cold air is blown onto the outer surface of the main pipe 1 through the top of the auxiliary ring 63, thereby completing the initial cooling of the capillary tube, avoiding the problem that the outer surface of the capillary tube is too soft and is stretched and deformed during winding, which affects the quality of the capillary tube. After entering the air duct 64, the cold air enters the rotating frame 66 through the dispersion holes 67 at the bottom of the rotating frame 66. The cold air is dispersed and softened by the inclined spiral rotating frame 66 and then the dispersion holes 67, thereby achieving a greatly improved moving speed of the cold air in the auxiliary ring 63 when cooling the capillary tube by the cold air, and limiting the cold air to flow out only through the bottom of the auxiliary ring 63, thereby greatly improving the cooling effect on the capillary tube.This avoids the problem of airflow collision and reduced cooling effect caused by the commonly used annular cooling nozzle 518. At the same time, the rotating frame 66 can significantly improve the uniformity of the cold air in the auxiliary ring 63 by homogenizing and dispersing the cold air, further improving the cooling effect on the capillary tube.
