Description

Technical Field

[0001] The invention relates to the technical field of rectangular tube cooling, and in particular to an automatic air supply cooling device for preventing rectangular tubes from burning out. Background Art

[0002] The matrix tube serves as the plasma generating tube of the inductively coupled plasma spectrometer. There are three coaxial channels with increasing diameters inside. The cooling gas passes through the outer and middle channels to cool the matrix tube around the plasma. The working gas is introduced from the middle pipe. When starting to work, the working gas is ionized by high-frequency coils and other high-voltage discharge devices to form a group of plasma torch areas with a temperature of up to 6000-10000 degrees Celsius. The sample is sprayed into the plasma torch through the central quartz tube in the form of aerosol through a super atomization device and decomposed into excited atoms and ions. When these excited particles are recovered to a stable ground state, they release a certain amount of energy. By measuring the unique spectral lines and intensities of each element, the type and content of the elements contained in the sample can be inferred to complete the detection work.

[0003] In the prior art, when the inductively coupled plasma spectrometer is working, during the continuous supply of gas source, tiny solid particles in the supply system such as dust, rust, oil droplets or other impurities enter the gas supply pipeline with the airflow, and are prone to gradually accumulate in the pipeline, eventually leading to blockage, causing insufficient supply of cooling gas, and further resulting in reduced cooling effect on the matrix tube in the reaction, which is not only prone to severe local heating of the matrix tube due to excessive temperature, but in severe cases may even cause the matrix tube to melt, deform or even burn, seriously affecting the normal detection work of the spectrometer.

[0035] It should be noted that the external inductively coupled plasma spectrometer is provided with a buzzer alarm electrically connected to the switch group 409. When the switch group 409 is triggered, the buzzer alarm will send out an alarm signal, and while switching the spare pipe 301 and the gas supply pipe 302, it will remind the staff that there is a problem with the gas supply of the gas supply pipe 302, and remind the staff to repair it in time.

[0038] Reference Figure 7 , the internal flow cross-sectional area of ​​the air groove 1 403 is greater than the internal flow cross-sectional area of ​​the air groove 2 404 .

[0039] It should be noted that the interior of the air intake block 300 is matched with the distribution contour of the push block 305, and there is a gap between the push block 305 and the inner wall of the air intake block 300.

[0042] Reference Figure 9-11 The top of the second spherical cavity 308 is connected to the second pipeline 208, and a through hole is provided inside the valve block 313.

[0043] Reference Figure 9-10 There are multiple groups of jet mechanisms distributed along the axis of the valve ring 303 , and the jet mechanism distribution span angle is smaller than the angle between the spare pipe 301 and the air supply pipe 302 .

[0044] It should be noted that the surface of blade 1 204 is provided with an adhesive coating.

[0045] The working process of the automatic air supply cooling device for preventing moment tube from burning out is as follows:

[0046] When the matrix tube body 100 inside the inductively coupled plasma spectrometer is working, the sample gas enters the matrix tube body 100 through the working gas pipe 103, and decomposes into excited atoms and ions in the high-temperature reaction area, while the cooling gas enters the matrix tube body 100 in turn through the gas supply pipe 302, the air intake block 300, the detection block 200 and the cooling gas pipe 101, entering in a tangential direction, forming a high-speed rotating air flow layer inside the matrix tube body 100, and taking away the heat generated by the reaction of the matrix tube body 100 by convection, thereby protecting the matrix tube body 100.

[0047] In this process, the cooling gas enters the air intake block 300 through the air supply pipe 302, and then enters the pipe 2 208 through the air duct 304, and then pushes the blade 204 to rotate through the spherical cavity 202 to enter the cooling air duct 101. The sticky coating on the surface of the spherical cavity 202 can capture impurities in the cooling gas, including dust, metal oxide particles, etc., through impact and contact with the cooling gas, effectively purify and filter the cooling gas, reduce the impact of impurities on detection, and improve detection efficiency. It should be noted that during normal operation, the valve ring 303 blocks the spare pipe 301, the air supply pipe 302 is connected to the air duct 304, and at the same time, the flow and pressure of the cooling gas are sufficient, which pushes the blade 204 to rotate rapidly. When the blade 204 rotates at high speed, the slider 206 rotates away from the rotation under the action of centrifugal force. The gas in the spherical cavity 202 enters the rotating shaft 203 through the gas path hole 207 under the action of pressure, and then enters the pressure block 400 through the pipe 201. When the cooling gas supply is sufficient, the spherical cavity 202 and the pressure block 400 both maintain a relatively high pressure. At this time, the slider 3 401 rises under the action of pressure, pushing the slider 402 to rise, so that the exhaust port 407, the valve port 408 and the gas groove 2 404 are in corresponding positions. The gas in the pressure block 400 is slowly discharged into the air intake block 300 through the air groove 2 404 and the connecting pipe 405 in small amounts, and then enters the exhaust pipe 307 through the gap between the push block 305 and the air intake block 300, and is discharged to the external exhaust gas treatment channel. Moreover, due to the small amount of gas, the valve ring 303 will not be pushed to rotate.

[0048] When the supply end of the gas supply pipe 302 is blocked, causing the cooling gas flow rate to decrease, the gas flow rate through the spherical cavity 202 decreases, and the blade 204 matches the inner contour of the spherical cavity 202. The gas flow through the spherical cavity 202 is associated with the rotation speed of the blade 204. When the gas flow rate decreases, the rotation speed of the blade 204 decreases synchronously, and the centrifugal force on the slider 206 decreases synchronously. When the refrigerant gas supply speed continues to decrease and approaches the minimum threshold, the centrifugal force on the slider 206 decreases and moves toward the shaft 203 to block the gas path hole 207. When the pressure block 400 loses the gas supply, under the elastic force of the spring between the slider 3 401 and the pressure block 400, the gas inside the pressure block 400 is slowly discharged through the gas groove 2 404 under the downward squeezing action of the slider 3 401. When the slider 3 401 moves downward, the slider 402 also gradually moves downward under the elastic force of the spring between the slider 401 and the pressure block 400, and is separated from the pressure on the switch group 409. At this time, the switch group 409 is triggered, and the external gas source is electrically connected to the switch group 409, and the gas supply end of the external gas source triggers the gas supply to the standby pipe 301 and the gas supply pipe 302. The countdown stops, and the gas supply to the gas supply pipe 302 is stopped after a few seconds. At the same time, the slider 402 moves downward to disconnect the gas groove 2 404 from the exhaust port 407 and the valve port 408, and the exhaust port 407 and the valve port 408 are connected to the connecting pipe 405 through the gas groove 1 403. Since the flow cross-sectional area of ​​the gas groove 1 403 is significantly increased, the exhaust speed through the connecting pipe 405 is significantly increased at this time, and the gas flow rate entering the inside of the air intake block 300 is also significantly increased. It is difficult for a large amount of gas to be completely discharged from the gap between the push block 305 and the air intake block 300, so that under the action of the gas pressure, the gas is pushed through the push block 305. Block 305 pushes the valve ring 303 to rotate slowly as a whole until the valve ring 303 rotates 180°, so that the airway 304 switches from rotating in coordination with the air supply pipe 302 to rotating in coordination with the spare pipe 301. During this process, the valve ring 303 rotates clockwise. During this process, the airway 304 rotates to be connected with the spare pipe 301, and the air supply pipe 302 gradually disconnects from the connection with the airway 304 under the rotation of the valve ring 303, and the air supply pipe 302 is blocked by the rotation of the valve ring 303, so that the air supply of the cooling air pipe 101 is gradually and automatically switched from the air supply pipe 302 to the spare pipe 301.

[0049] It should be noted that the connecting pipe 405 enters the air intake block 300 in a tangential direction, thereby pushing the valve ring 303 to rotate in a specified direction.

[0050] It should be noted that the switch group 409 is a push-type switch, which is ready to store power when pressed and is triggered when released.

[0051] It should be noted that the external gas supply source has working indicator lights for the gas supply pipe 302 and the spare pipe 301. The staff can judge the gas supply conditions of the gas supply pipe 302 and the spare pipe 301 through the prompts of the buzzer alarm and the working indicator lights of the gas supply source, and then carry out maintenance.

[0052] It should be noted that when the slider 3 401 moves down to contact the slider 5 406, the downward movement will push the slider 5 406. When the slider 5 406 moves down, the valve port 408 and the exhaust port 407 are misaligned and thus disconnected. Further, the bottom magnet of the slider 5 406 cooperates with the magnet inside the pressure block 400 to attract. In the initial state, when the air inlet block 300 begins to be ventilated, the gas enters the pressure block 400, and the misalignment between the exhaust port 407 and the valve port 408 makes the air inside the pressure block 400 There is no exhaust channel in the body, so that the internal pressure of the pressure block 400 increases, pushing the slider three 401 to move up, until the slider three 401 moves up and pushes the slider four 402 to move up, and the slider five 406 is pulled up by the spring between the slider four 402 and the slider five 406, and the magnetic block at the bottom of the slider five 406 is disconnected from the pressure block 400. At this time, the exhaust port 407, the valve port 408, the air groove two 404 and the connecting pipe 405 form a group of passages, thereby preparing for the subsequent pressure change to switch the air source.

[0053] It should be noted that during the rotation of the valve ring 303, the airway 304 first rotates to communicate with the spare pipe 301, blocking the air supply pipe 302. When the rotation continues, the arc-shaped design of the airway 304 can maintain communication with the spare pipe 301, and the air supply pipe 302 will pass through each group of spherical cavities 308 in turn. When the airway 304 is connected with the spare pipe 301 and the valve ring 303 blocks the air supply pipe 302, the gas flow rate entering the interior of the rectangular tube body 100 is the gas supply amount of the spare pipe 301. When the spherical cavity 308 is in contact and connected with the air supply pipe 302, the gas inside the air supply pipe 302 enters the air intake block 300 through the spherical cavity 308. At this time, the gas flow rate entering the interior of the rectangular tube body 100 is the gas flow rate of the spare pipe 301 and the air supply pipe. 302 gas supply, the speed and flow rate of the cooling gas entering the rectangular tube body 100 will be partially improved, and when the valve ring 303 continues to rotate so that the group of spherical cavities 2 308 pass through the gas supply pipe 302, the gas flow rate and speed of the cooling gas entering the rectangular tube body 100 will return to the standard level. When the valve ring 303 continues to rotate so that each group of spherical cavities 2 308 passes through the gas supply pipe 302 in turn, the gas flow rate entering the rectangular tube body 100 will show a regular increase and then reset fluctuation change until the valve ring 303 rotates 180°. At this time, under the coordinated attraction of the magnetic ring at the top of the spare tube 301 and the magnet at the bottom of the valve ring 303, the valve ring 303 is positioned and fixed, so that the valve ring 303 rotates from the gas supply pipe 30 2 is switched to cooperate with the spare pipe 301. During the switching process, through this design, after the rectangular tube body 100 automatically changes the gas source, the rectangular tube body 100 can be purged and cleaned by fluctuating pressurized gas supply to the rectangular tube body 100. The periodically changing pressure and flow rate generated by the fluctuating pressurized purge can generate a higher gas flow rate and impact force in the pressurization stage compared with a stable airflow. When the cooling gas impacts the inner wall of the rectangular tube body 100 at a higher flow rate, it can more effectively remove impurities attached to the wall surface. In addition, in the rectangular tube body 100, impurity particles may agglomerate with each other on the inner wall of the rectangular tube body 100 to form larger aggregates. The complex airflow conditions of the fluctuating pressurized purge can The agglomeration of impurity particles is suppressed. The fluctuating pressure and flow rate will cause the particles to constantly collide and disperse with each other, preventing them from forming larger aggregates and accelerating their separation, thereby reducing the risk of impurities being deposited in the rectangular tube body 100, thereby avoiding the thermal resistance layer and deposited particles formed by the deposition. This not only improves the efficiency of energy exchange when the rectangular tube body 100 is working, but also reduces product pollution and the stability of internal gas circulation, ensuring the accuracy of the detection work. Moreover, when the gas inside the air supply pipe 302 passes through the spherical cavity 308, it can drive the blade 309 to rotate. The greater the internal pressure of the air supply pipe 302, the faster the gas speed entering the air intake block 300 through the spherical cavity 308, and the corresponding blade 309 rotates faster.When the speed of blade 2 309 is faster, the speed of corresponding shaft 2 311 and turntable 310 is also faster, and the centrifugal force on slider 2 315 is also greater. When slider 2 315 moves away from shaft 2 311 under the action of centrifugal force, the hydraulic oil inside shaft 2 311 can be drawn away from shaft 2 311. Under the action of communication, the hydraulic oil inside sealing chamber 312 is drawn toward the inside of sealing groove 314, so that the pressure inside sealing chamber 312 is reduced, thereby pulling valve block 313, reducing the opening between the through hole inside valve block 313 and the bottom of spherical chamber 2 308. The overlap of the openings automatically adjusts the air intake cross-sectional area at the bottom of the second spherical cavity 308, thereby reducing the amount of cooling gas entering the air intake block 300 through the second spherical cavity 308 through the air supply pipe 302, thereby controlling the range of pressurization through the air supply pipe 302 during pressurization and purging of the interior of the rectangular tube body 100, and controlling the gas flow and pressure when the air supply pipe 302 and the spare pipe 301 act together on the interior of the rectangular tube body 100. While ensuring pressurization and purging, it avoids excessive pressure affecting the normal operation of the rectangular tube body 100, and effectively ensures the stable operation of purging and cooling.
