Description

Technical Field

[0001] This invention relates to the field of chromatography column aging technology, specifically to a semiconductor temperature-controlled chromatography column aging device. Background Technology

[0002] The chromatographic column is the core component of a chromatographic analysis system, and its performance directly affects the separation effect and the reliability of the analytical results. Newly packed or long-unused chromatographic columns must be aged before use. This involves programmed temperature increase to homogenize the stationary phase, remove residual solvents and low-boiling-point impurities, thereby stabilizing the baseline, improving column efficiency, and extending the column's lifespan. Existing column aging technologies mainly employ two modes: First, in-situ aging using the chromatograph's built-in column oven. This method places the column inside the chromatograph's column oven and heats it through an air bath or metal block conduction, raising the temperature to the stationary phase's tolerance temperature according to a preset program and maintaining it for several hours. Second, using a separate column aging chamber. Although such equipment can process multiple columns in batches, it is still based on traditional heating principles, resulting in a large size, high power consumption, and poor temperature uniformity across different column positions. It also cannot implement differentiated temperature control strategies for columns of different specifications or stationary phase types.

[0003] The existing Chinese patent with publication number CN212568635U includes an insulated box, an air inlet, an air outlet, a capillary chromatographic column, a display screen, an operation panel, an electronic flow meter, and a temperature control module. The insulated box is equipped with a temperature control module and a capillary chromatographic column. The front face of the insulated box is equipped with a display screen and an operation panel, and the temperature control module is electrically connected to the operation panel. The upper face of the insulated box is equipped with an electronic flow meter.

[0004] When the above-mentioned device is used, it solves the problem that the capillary column aging process occupies the gas chromatograph's operating time and hinders other gas chromatography experiments. However, in actual use, the traditional chromatograph heating box uses resistance wire or heating rod as a heat source, which has large thermal inertia and slow temperature response, making it difficult to achieve rapid heating and precise temperature control, thus affecting the quality and efficiency of column aging.

[0005] Therefore, we propose a semiconductor temperature-controlled chromatography column aging device. Summary of the Invention

[0006] The purpose of this invention is to provide a semiconductor temperature-controlled chromatographic column aging device, which has the advantages of rapid heating and precise temperature control of the chromatograph heating chamber, and solves the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a semiconductor temperature-controlled chromatographic column aging device includes a control box, a heating outer box, and a turbulence-inducing mechanism and an adjustment mechanism disposed in the heating inner box; the turbulence-inducing mechanism and the adjustment mechanism are disposed on the upper part of the chromatographic column body; both ends of the chromatographic column body are connected to the heating inner box through an inlet plate sleeve and an outlet plate sleeve, respectively; the control box is connected to the inlet plate sleeve through a mass flow controller; semiconductor heating plates are symmetrically disposed on the inner wall of the heating inner box; the turbulence-inducing mechanism can purge the hot air in the heating inner box; the adjustment mechanism can adjust the airflow of the turbulence-inducing mechanism according to the temperature in the heating inner box.

[0008] Furthermore, the turbulence mechanism includes a power mechanism, a rotating head, and turbulence blades. The output shaft of the power mechanism is rotatably connected to the fixed axis of the rotating head. The rotating head is disposed within the heating inner chamber. Two turbulence blades are radially connected through the rotating head. Furthermore, the adjustment mechanism includes a piston plate, a rack, and a gear disposed within the rotating head. The rack is fixedly connected to the piston plate. The gear is fixedly connected to the root of the turbulence blades. The rack meshes with the gear. The side of the piston plate opposite to the rack is filled with alcohol.

[0009] Furthermore, a pressure sensor is fixedly connected to the inner wall of the rotating head at the end away from the piston plate, and a fixing block is fixedly connected to the end of the two racks at the end away from the piston plate. A compression spring is fixedly connected to the surface of the fixing block and the pressure sensor to allow the piston plate to move axially and apply pressure to the pressure sensor.

[0010] Furthermore, two cylindrical shells are fixedly connected to the inner wall of the heating chamber near the control box; an input pipe and an output pipe are respectively connected to the ends of the cylindrical shells; the ends of the two output pipes away from the cylindrical shells are respectively connected to an inlet through-plate sleeve; a sample box for storing samples is fixedly connected to the inner wall of the control box; the ends of the two input pipes away from the cylindrical shells are respectively connected to the sample box.

[0011] Furthermore, it also includes a sample injection mechanism; the sample injection mechanism includes a piston rod, a one-way inlet valve, and a one-way outlet valve; the piston rod is inserted into the cylindrical housing; the one-way inlet valve is disposed in the inlet pipe; the one-way outlet valve is disposed in the outlet pipe.

[0012] Furthermore, a reciprocating lead screw is rotatably connected to the inner wall of the heating chamber near the cylindrical shell, with the lead screw having a through-hole. A movable sleeve is fitted onto the side wall of the reciprocating lead screw, and the movable sleeve is screwed to the reciprocating lead screw. The ends of the two piston rods away from the cylindrical shell are fixedly connected to the movable sleeve. A first pulley is coaxially fixedly connected to the end of the reciprocating lead screw away from the cylindrical shell. A second pulley is fixedly connected to the outer contour of the rotating head. The first pulley and the second pulley are connected by a transmission belt.

[0013] Furthermore, the gap between the heating outer box and the heating inner box is filled with aluminum silicate insulation cotton.

[0014] Furthermore, the control box is equipped with a control display screen; the control display screen can control the opening and closing of the semiconductor heating element. Furthermore, multiple chromatographic column bodies are horizontally arranged within the heating inner chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the set turbulence mechanism, the rotating head driven by the motor rotates on a fixed axis in the heating inner chamber, thereby driving the turbulence blades on both sides to rotate synchronously. This can forcefully agitate and purge the hot air flow in the heating inner chamber, effectively breaking the hot air stratification and local temperature difference caused by static heating. This allows heat to be transferred to each chromatographic column body more quickly and evenly, ensuring that multiple chromatographic columns can be aged in a consistent temperature environment. This fundamentally solves the problem of poor temperature uniformity in traditional aging chambers and significantly improves the quality and effect of chromatographic column aging.

[0017] Second, through the set adjustment mechanism, the alcohol sealed in the rotating head is heated and expanded as a power source to drive the piston plate to move axially. Through the meshing of the rack and gear, the deflection angle of the disturbance blade is automatically adjusted. The higher the temperature, the greater the expansion of the alcohol, and the stronger the stirring intensity of the disturbance blade.

[0018] Meanwhile, the temperature signal is converted into a pressure signal for monitoring by transmitting the pressure to the pressure sensor through the compression spring. When the temperature exceeds the set threshold, the control box can automatically cut off the power to the semiconductor heating element, forming a rapid-response intelligent constant temperature and overheat protection system that does not require external intervention, effectively preventing damage to the chromatographic column caused by overheating.

[0019] Third, the sample introduction mechanism enables automatic and quantitative sample introduction during the aging process. By utilizing the transmission belt and reciprocating screw linked to the rotating head, the power of the hot air circulation is cleverly converted into the reciprocating motion of the piston rod within the cylindrical housing. Combined with the one-way liquid inlet valve and one-way liquid outlet valve on the inlet and outlet pipes, the reciprocating motion of the piston rod can accurately and quantitatively extract the sample from the sample box and smoothly push it into the inlet plate sleeve at the column inlet. This achieves synchronization and automation of the sample introduction action and the heating aging process, which not only improves the accuracy and consistency of sample introduction and reduces human error, but also enhances the overall automation level and working efficiency of the entire aging device.

[0020] The combined use of the above structures solves the problem that in practical use, traditional chromatograph heating chambers use resistance wires or heating rods as heat sources, which have large thermal inertia and slow temperature response, making it difficult to achieve rapid heating and precise temperature control, thus affecting the efficiency and quality of column aging.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 8 This invention provides a technical solution: a semiconductor temperature-controlled chromatographic column aging device, comprising a control box 1, a heating outer box 2, and a turbulence-inducing mechanism and an adjustment mechanism disposed in a heating inner box 3; the turbulence-inducing mechanism and the adjustment mechanism are disposed on the upper part of the chromatographic column body 6; both ends of the chromatographic column body 6 are connected to the heating inner box 3 through an inlet plate sleeve 4 and an outlet plate sleeve 5, respectively; the control box 1 is connected to the inlet plate sleeve 4 through a mass flow controller 7; semiconductor heating elements 8 are symmetrically disposed on the inner wall of the heating inner box 3; the turbulence-inducing mechanism can purge the hot air in the heating inner box 3; the adjustment mechanism can adjust the airflow of the turbulence-inducing mechanism according to the temperature in the heating inner box 3; multiple chromatographic column bodies 6 are horizontally disposed in the heating inner box 3; the control box 1 is provided with a control display screen 10; the control display screen 10 can control the opening and closing of the semiconductor heating elements 8.

[0032] Specifically, the control box 1 is fixedly supported on the heating outer box 2, and the heating inner box 3 can be fixedly supported on the inner wall of the heating outer box 2 by bolts, so that the heating inner box 3 can be detachably connected to the heating outer box 2. Compared with the welding assembly method, the number of welds is effectively reduced, the quality of the box is improved from the design, and the effects of a large number of welds, such as box deformation and incomplete welding, are eliminated.

[0033] The chromatographic column body 6 is fixedly supported on the inlet perforation sleeve 4 and the outlet perforation sleeve 5. There are multiple sets of inlet perforation sleeves 4 and outlet perforation sleeves 5, which can be used to age multiple chromatographic column bodies 6. The mass flow controller 7 and the control display screen 10 are electrically connected to the control box 1. The output terminal of the mass flow controller 7 is connected to the two sets of inlet perforation sleeves 4. At this time, the operator operates the control display screen 10 and starts the mass flow controller 7 through the control box 1, so that the mass flow controller 7 can purge the inside of the inlet perforation sleeve 4 with a high-purity nitrogen or helium flow rate through the output terminal. The experimenter can control the control box 1 to start the semiconductor heating element 8 through the control display screen 10, so that the semiconductor heating element 8 can quickly heat the inside of the heating chamber 3. The use of semiconductor heating can realize the rapid heating and cooling of the inside of the heating chamber 3. Along with the purging of the inside of the inlet perforation sleeve 4 with a high-purity nitrogen or helium flow rate, impurities generated during heating can be discharged, effectively improving the performance of the chromatographic column body 6.

[0034] The turbulence mechanism can agitate the hot airflow inside the heating chamber 3 and distribute it evenly inside the heating chamber 3, so as to avoid large local temperature differences on the inner wall of the heating chamber 3, which would affect the aging quality of the chromatographic column body 6. The adjustment mechanism can monitor the temperature inside the heating chamber 3 and adjust the intensity of the turbulence mechanism's disturbance of the hot airflow and the working status of the semiconductor heating element 8.

[0035] In this scheme, the turbulence mechanism includes a power mechanism, a rotating head 12 and turbulence blades 13. The output shaft of the power mechanism is rotatably connected to the rotating head 12. The rotating head 12 is located inside the heating inner box 3. Two turbulence blades 13 are connected radially through the rotating head 12. The gap between the heating outer box 2 and the heating inner box 3 is filled with aluminum silicate insulation cotton 9.

[0036] During use, the aluminum silicate insulation cotton 9 installed on the inner heating box 3 is heated, and the aluminum silicate insulation cotton 9 is located between the inner heating box 3 and the outer heating box 2 and is kept in a sealed state, which improves the heat preservation performance of the inner heating box 3 and slows down the loss of heat inside the inner heating box 3.

[0037] The rotating head 12 can rotate on a fixed axis on the inner heating chamber 3. The power mechanism is a motor after being powered on, and the output shaft of the motor is coaxially fixed to the rotating head 12. When the motor is started, it drives the rotating head 12 to rotate on a fixed axis on the inner wall of the inner heating chamber 3. The agitator blade 13 rotates on a fixed axis along with the rotating head 12 and agitates the hot airflow inside the inner heating chamber 3, ensuring the uniform distribution of the hot airflow inside the inner heating chamber 3. This effectively breaks the hot air stratification and local temperature difference caused by static heating, which allows the heat to be transferred to each chromatographic column body 6 more quickly and evenly. This ensures that multiple chromatographic column bodies 6 can be aged in a consistent temperature environment, fundamentally solving the problem of poor temperature uniformity in traditional aging chambers and significantly improving the quality and effect of chromatographic column aging.

[0038] In this design, the adjustment mechanism includes a piston plate 14, a rack 15, and a gear 16 disposed within the rotating head 12; the rack 15 is fixedly connected to the piston plate 14; the gear 16 is fixedly connected to the root of the disturbance blade 13; the rack 15 and the gear 16 are meshed together; the side of the piston plate 14 facing away from the rack 15 is filled with alcohol.

[0039] A pressure sensor 17 is fixedly connected to the inner wall of the rotating head 12 away from the piston plate 14. A fixing block 18 is fixedly connected to the end of the two racks 15 away from the piston plate 14. A compression spring 19 is fixedly connected to the opposite surface of the fixing block 18 and the pressure sensor 17, which allows the piston plate 14 to move axially and apply pressure to the pressure sensor 17.

[0040] Specifically, the piston plate 14 can be axially moved along the inner wall of the rotating head 12. The rack 15 is fixedly supported on the piston plate 14, and the gear 16 on the disturbance blade 13 enables the rack 15 to mesh with the teeth on the rack 15 for transmission. The inner wall of the rotating head 12 is provided with alcohol that is easily expanded by heat. As the temperature inside the heating inner box 3 gradually rises, the alcohol on the inner wall of the rotating head 12 expands and pushes the piston plate 14 and the rack 15 toward the disturbance blade 13. The gear 16 is also able to move axially along the inner wall of the rotating head 12. Under the action of the rack 15, the agitator blade 13 is driven to rotate on the fixed axis of the rotating head 12. As the deflection angle between the agitator blade 13 and the rotating head 12 increases, the agitation intensity of the agitator blade 13 on the hot airflow inside the heating chamber 3 is enhanced. This realizes automatic adjustment of the deflection angle of the agitator blade. The higher the temperature, the greater the expansion of alcohol, and the agitation intensity of the agitator blade is also enhanced. This accelerates the uniform distribution of the hot airflow on the inner wall of the heating chamber 3, avoiding the problem of excessively high local temperature on the inner wall of the heating chamber 3, which could lead to damage and scrapping of the chromatographic column body 6.

[0041] Furthermore, as the piston plate 14 pushes the rack 15 to move closer to the disturbance blade 13, the fixed block 18 can compress the compression spring 19 under the action of the rack 15. At the same time, the compression spring 19 can apply pressure to the pressure sensor 17 under its own elastic force. The pressure sensor 17 is electrically connected to the control display screen 10, so that the pressure sensor 17 can convert the detected pressure value into an electrical signal and remotely transmit it to the control display screen 10. When the pressure sensor 17 detects that the pressure value exceeds the set threshold, the control display screen 10 turns off the semiconductor heating element 8 through the control box 1, and the semiconductor heating element 8 stops heating the inside of the heating chamber 3.

[0042] In this design, two cylindrical shells 21 are fixedly connected to the inner wall of the heating inner box 3 near the control box 1; an input pipe 22 and an output pipe 23 are respectively connected to the ends of the cylindrical shells 21; the ends of the two output pipes 23 away from the cylindrical shells 21 are respectively connected to an inlet through-plate sleeve 4; a sample box 20 for storing samples is fixedly connected to the inner wall of the control box 1; the ends of the two input pipes 22 away from the cylindrical shells 21 are respectively connected to the sample box 20.

[0043] It also includes a sample injection mechanism; the sample injection mechanism includes a piston rod 24, a one-way liquid inlet valve 221 and a one-way liquid outlet valve 231; the piston rod 24 is inserted into the cylindrical housing 21; the one-way liquid inlet valve 221 is located in the inlet pipe 22; the one-way liquid outlet valve 231 is located in the outlet pipe 23; the inner wall of the heating inner chamber 3 is penetrated on the side near the cylindrical housing 21 and is rotatably connected to a reciprocating screw 26; a movable sleeve 25 is sleeved on the side wall of the reciprocating screw 26, and the movable sleeve 25 is screwed to the reciprocating screw 26; the ends of the two piston rods 24 away from the cylindrical housing 21 are fixedly connected to the movable sleeve 25; the ends of the reciprocating screw 26 away from the cylindrical housing 21 are coaxially fixedly connected to a first pulley 27; a second pulley 28 is fixedly connected to the outer contour of the rotating head 12; the first pulley 27 and the second pulley 28 are connected by a transmission belt 29.

[0044] Specifically, the output tube 23 connects the inlet plate sleeve 4 to the cylindrical shell 21; at the same time, the input tube 22 connects the cylindrical shell 21 to the sample box 20; the sample is stored in the sample box 20, and the sample inside the sample box 20 is quantitatively extracted and transported to the inlet plate sleeve 4 by the sample injection mechanism set on the cylindrical shell 21, thus realizing automatic sample injection.

[0045] The piston rod 24 can move axially along the inner wall of the cylindrical housing 21. Through the one-way liquid inlet valve 221 and one-way liquid outlet valve 231 provided on the inlet pipe 22 and the outlet pipe 23, the piston rod 24 can perform fixed-axis extraction or discharge of the sample inside the sample box 20.

[0046] One end of the reciprocating lead screw 26 is coaxially fixed to a first pulley 27; the rotating head 12 is also rotatably mounted on a fixed axis inside the heating inner box 3, and a second pulley 28 is fixed on it, rotating synchronously with the rotating head 12. The first pulley 27 and the second pulley 28 are connected by a transmission belt 29, forming a belt drive mechanism; when the rotating head 12 drives the second pulley 28 to rotate, the first pulley 27 is driven to rotate through the transmission belt 29, thereby driving the reciprocating lead screw 26 to rotate around its axis.

[0047] Since the movable sleeve 25 is threadedly engaged with the reciprocating screw 26 and connected to the piston rod 24, the movable sleeve 25 can drive the piston rod 24 to make axial reciprocating motion in the inner wall of the cylindrical housing 21 during the rotation of the reciprocating screw 26.

[0048] In addition, because the radius of the first pulley 27 is larger than that of the second pulley 28, the transmission structure has the effect of speed reduction and torque increase, so that the reciprocating screw 26 pushes the piston rod 24 slowly and stably through the moving sleeve 25.

[0049] In actual use, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in the initial state, the piston rod 24 is located at the end of the cylindrical shell 21 away from the input pipe 22, and the piston rod 24 draws the sample from the sample box 20 into the cylindrical shell 21. When the piston rod 24 moves axially toward the end closer to the input pipe 22, the internal air pressure of the cylindrical shell 21 near the input pipe 22 becomes positive. At this time, the one-way liquid inlet valve 221 is closed and the one-way liquid outlet valve 231 is open, so the piston rod 24 can slowly push the sample inside the cylindrical shell 21 through the output pipe 23 into the inlet plate sleeve 4.

[0050] When the piston rod 24 moves axially to the end away from the input tube 22, the above structure moves synchronously in the opposite direction. Thus, the piston rod 24 can extract the sample from inside the sample box 20 to the inner wall of the cylindrical shell 21 through the input tube 22, realizing the synchronization and automation of the sample injection action and the heating aging process. This not only improves the accuracy and consistency of sample injection and reduces human error, but also enhances the overall automation level and working efficiency of the entire aging device.

[0051] Furthermore, the existing device can rapidly heat up and precisely maintain the temperature of the chromatograph heating chamber during actual use.

[0052] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
