Description

Technical Field

[0001] The present application relates to the technical field of mass spectrometers, and in particular to a nebulizer for an inductively coupled plasma emission mass spectrometer. Background Art

[0002] In many fields such as environmental protection, electronics, and medicine, gas chromatography-mass spectrometry has been widely used due to its powerful detection and analysis capabilities. The ion source device of the mass spectrometer often uses a discharge needle, which uses a high-voltage power supply to ionize the atomized droplets with high voltage as an ion source. Although this structure is simple, it has obvious defects. On the one hand, the contact between the discharge needle and the atomized droplets is limited, resulting in an unstable ion beam, which affects the reliability of the detection results; on the other hand, the lack of a restraint device makes it difficult for the ion beam ionized by the discharge needle to stably pass into the mass spectrometer, which can easily cause detection errors and reduce detection accuracy;

[0003] In response to the above problems, a Chinese patent with the announcement number "CN213459639U" discloses a nebulizer for an inductively coupled plasma emission mass spectrometer, which attempts to extend the contact time between the discharge device and the atomized droplets by integrating the discharge device with the atomizer outlet. However, the device still has significant defects during actual operation. In its work process, the atomizing gas needs to pass through the box quickly. Due to the excessively fast gas flow rate, the contact time between the atomizing gas and the discharge rod is extremely short. In most cases, a large amount of atomizing gas has not yet undergone sufficient ionization reaction with the discharge rod, and is quickly discharged from the box under the influence of the airflow. This rapid gas flow not only makes it impossible for the atomizing gas to achieve Complete ionization also causes an uneven reaction process, resulting in complex ion beam composition and low ionization efficiency. After the incompletely reacted atomized gas enters the mass spectrometer, it will interfere with the normal detection signal, generate a lot of noise and false positive results, and seriously affect the detection accuracy and reliability of the analysis results. In addition, the uneven reaction process will also lead to large differences between the test results of different batches, reducing the consistency and comparability of the test results, and it is difficult to meet the strict requirements of modern high-precision detection for data accuracy and stability. It can be seen that the existing technology has certain defects and deficiencies and needs to be improved and designed. Summary of the Invention

[0016] When the device is in operation, the atomizer body operates, the air pump discharges the atomized gas into the tank body through the pipeline, closes the second connecting valve to seal the bottom of the tank body, and closes the first connecting valve after the gas is injected. Then, the reaction gas can be introduced through the second connecting valve, or the reaction gas and the atomized gas can be injected simultaneously through the first connecting valve and the third connecting valve respectively. When the gas is injected, the second connecting valve remains closed, the air pressure in the tank rises, and the gas enters the gas containing pipe through the connecting groove, pushing the piston plate outward to create more space in the gas containing pipe to accommodate the gas. The outward movement of the piston plate drives the piston rod, the connecting frame and the slip ring to move, stretching the telescopic spring to provide power preparation for subsequent gas reaction and discharge, and also can further container reaction gas.

After the reaction is completed, the second connecting valve is opened, the air pressure in the tank drops, the telescopic spring is reset, and the piston plate is pushed inward to discharge the reacted gas through the second connecting valve and the exhaust pipe. During exhaust, the driving motor drives the spiral power paddle at the bottom of the rotating shaft to rotate to accelerate the gas flow, and the spiral drive paddle can also promote gas mixing during the reaction process. The cyclically driven reaction plate and the elastic container work together to ensure uniform gas mixing and sufficient reaction, which can further improve the detection accuracy.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-8 This application is described in further detail.

[0030] The present application discloses a nebulizer for an inductively coupled plasma emission mass spectrometer. Figure 1-8The nebulizer body 2 is fixedly mounted on the top of the nebulizer body 2, and an air pump 3 is fixedly mounted on the top of the nebulizer body 2. A first connecting valve 4 is fixedly mounted on the output end of the air pump 3. A connecting plate 5 is fixedly mounted on one side of the mounting base 1, and a lifting mechanism 6 is fixedly mounted on the outer end of the connecting plate 5. A mixing mechanism 7 is fixedly mounted on the outer end of the lifting mechanism 6. A mounting bracket 8 is fixedly mounted on the side of the nebulizer body 2 close to the lifting mechanism 6, and a tank body 10 is fixedly mounted on the inner side of the mounting bracket 8. The mixing mechanism 7 covers the top of the tank body 10, and the bottom of the mixing mechanism 7 extends into the interior of the tank body 10. Elastic containers 9 are fixedly mounted on the outer surface of the tank body 10 at equal intervals, and the inner end of the elastic container 9 is connected to the interior of the tank body 10. An exhaust pipe 11 is fixedly mounted on the bottom of the tank body 10, and a second connecting valve 12 is fixedly mounted on the input end of the exhaust pipe 11. During use, when the inductively coupled plasma emission mass spectrometer is working with the nebulizer, the nebulizer body 2 atomizes the liquid under the action of the air pump 3, and the mist is The atomized gas is discharged through the first connecting valve 4 at the output end of the air pump 3. The lifting mechanism 6 can be fixed to one side of the mounting base 1 by a connecting plate 5. The lifting operation of the mixing mechanism 7 can be realized by the lifting mechanism 6. When the mixing mechanism 7 descends to cover the top of the tank body 10, its bottom extends to the inside of the tank body 10, forming a closed reaction space. At this time, the atomized gas can be transported to the inside of the tank body 10 through a pipeline. At the same time, the reaction gas can be introduced into the tank body 10 through other channels as needed. As the gas continues to enter, the air pressure in the tank increases, and the gas enters the elastic container 9 installed at equal intervals outside the tank body 10 through the connecting part, pushing the internal components of the elastic container 9 to move, providing space for the tank body 10 to accommodate more gas. In the tank body 10, the mixing mechanism 7 stirs and mixes the gas to promote the full reaction of the atomized gas and the reaction gas. After the reaction is completed, the second connecting valve 12 on the exhaust pipe 11 at the bottom of the tank body 10 is opened, and the reacted gas is discharged through the exhaust pipe 11, completing the entire gas reaction and discharge process.

[0031] Please refer to Figures 1-6The lifting mechanism 6 includes a vertical rail 61, which is fixedly mounted on the end of the connecting plate 5 away from the tank body 10. The bottom of the vertical rail 61 is fixedly connected to a second motor 62. The output end of the second motor 62 is fixedly mounted with a screw rod 63. The screw rod 63 is rotatably connected to the inside of the vertical rail 61. The outer surface of the screw rod 63 is threadedly connected to a slider 64. The slider 64 is slidably connected to the inside of the vertical rail 61. A connecting frame 65 is fixedly mounted on the side of the slider 64 close to the tank body 10. The outer end of the connecting frame 65 is fixedly connected to the mixing mechanism 7. The mixing mechanism 7 includes a sealing cover 71, the sealing cover 71 is fixedly installed on the top of the lifting mechanism 6, and a first motor 72 is fixedly installed in the middle of the top of the sealing cover 71. The output end of the first motor 72 passes through the sealing cover 71 and is fixedly connected to the mixing assembly 73. The sealing cover 71 covers the top of the tank body 10. A third connecting valve 74 is fixedly installed in the middle of the side of the top of the sealing cover 71 away from the lifting mechanism 6. The output end of the third connecting valve 74 passes through the sealing cover 71 and is connected to the inside of the tank body 10. This device works in conjunction with the lifting mechanism 6 and the mixing mechanism 7 so that when the tank body needs to be adjusted, When cleaning, repairing or adjusting the position of the mixing mechanism 7 inside the vertical rail 61, the second motor 62 at the bottom of the vertical rail 61 can be started, and the output end of the second motor 62 drives the screw rod 63 to rotate. Since the screw rod 63 is connected to the slider 64 by a thread, and the slider 64 is slidably connected to the inside of the vertical rail 61, when the screw rod 63 rotates, the slider 64 will slide in the vertical direction along the vertical rail 61. The connecting frame 65 fixed on the side of the slider 64 close to the tank body 10 is connected to the sealing cover 71, so the sliding of the slider 64 will drive the connecting frame 65, and then drive the sealing cover 71 to And the mixing mechanism 7 fixed on the sealing cover 71 rises or falls. When the sealing cover 71 covers the top of the tank body 10, the reaction gas or other medium can be introduced into the tank body 10 through the third connecting valve 74. At the same time, the first motor 72 fixed on the sealing cover 71 is started, and its output end drives the mixing assembly 73 to rotate inside the tank body 10, stirring and mixing the atomized gas, reaction gas, etc. in the tank body 10, promoting full reaction between the gases, ensuring the reaction effect and efficiency, and meeting the sample processing requirements of the inductively coupled plasma emission mass spectrometer.

[0032] Please refer to Figure 4-Figure 6 and Figure 9The bottom of the mixing assembly 731 includes a rotating shaft 731, which is rotatably connected to the bottom of the sealing cover 71. The outer surface of the rotating shaft 731 is fixedly installed with reaction plates 732 at equal intervals. The reaction plates 732 include a base plate 7321, and the base plate 7321 is fixedly installed on the outer surface of the rotating shaft 731 at equal intervals. The base plate 7321 is provided with a groove body 7322. The interior of the groove body 7322 is fixedly installed with partitions 7323 at equal intervals. The interior of the groove body 7322 is fixedly installed with a discharge rod 7324. The bottom of the rotating shaft 731 is fixedly installed with a propeller 75. The propeller 75 is conical in shape as a whole. The bottom of the tank body 10 is also conical. The bottom of the sealing cover 71 is fixedly installed with a covering sealing ring 76. The covering sealing ring 76 covers the upper end of the outer surface of the tank body 10. During the application of the device, when the mixing assembly 73 is working, the first motor 72 is started to drive the rotating shaft 731 to rotate, and the reaction plate 732 fixed on the outer surface of the rotating shaft 731 rotates accordingly. A groove 7322 is provided on the substrate 7321 of 32, and a partition 7323 is provided in the groove 7322. The partition 7323 divides the groove 7322 into multiple independent spaces. The discharge rod 7324 is fixed inside the groove 7322. When the reaction plate 732 rotates, the discharge rod 7324 makes a circular motion in the tank body 10, fully contacting the atomized gas and the reaction gas in the tank body 10, promoting gas ionization and chemical reaction. At the same time, the propeller 75 at the bottom of the rotating shaft 731 rotates with the rotating shaft 731. Its conical structure is adapted to the conical design of the bottom of the tank body 10. During the rotation of the propeller 75, the gas is pushed to circulate in the tank body 10, making the gas mixing more uniform and enhancing the reaction effect. In addition, the covering sealing ring 76 at the bottom of the sealing cover 71 is tightly covered on the upper end of the outer side of the tank body 10, ensuring the sealing of the tank body 10, preventing gas leakage, and ensuring that the entire reaction process is carried out stably in a closed environment, thereby improving the accuracy and reliability of the detection.

[0033] Please refer to Figure 1-Figure 5The top of the mounting base 1 is provided with mounting holes 13 arranged in a ring at equal intervals, and the mounting holes 13 are set as countersunk holes. During the use of this device, the mounting holes 13 arranged in a ring at equal intervals on the top of the mounting base 1 are set as countersunk holes. During the installation of the equipment, this design is convenient for fixing other components to the mounting base 1 by connecting parts such as bolts. The countersunk holes can make the heads of the bolts sink into the holes and be flush with or lower than the surface of the mounting base 1. On the one hand, it can avoid interference caused by the protruding heads of the bolts, ensure the flatness of the overall structure of the equipment, and prevent collision and scratching with surrounding components during the subsequent installation of other components or operation of the equipment; on the other hand, it can make the fit between the mounting base 1 and the mounted components closer, improve the stability and reliability of the connection, and enhance the overall structural strength of the equipment. At the same time, the distribution of the mounting holes 13 arranged in a ring can evenly disperse the force on the connecting components, make the connection between the mounting base 1 and the mounted components more stable, effectively reduce the risk of loosening caused by uneven force, and ensure stable operation of the equipment.

[0034] Please refer to Figure 5-Figure 8The elastic container 9 includes a mounting ring 91 and a communicating groove 92. The mounting ring 91 is fixedly installed on the outer surface of the tank body 10 at equal intervals. The communicating grooves 92 are also opened on the outer surface of the tank body 10 at equal intervals. The outer side of the mounting ring 91 is fixedly connected to the air-containing pipe 93. The outer side of the air-containing pipe 93 is fixedly connected to an elastic piston 94. The elastic piston 94 is movably connected to the inside of the air-containing pipe 93. The inner side of the air-containing pipe 93 is connected to the inner side of the communicating groove 92. The elastic piston 94 includes a telescopic spring 941. The telescopic spring 941 is fixedly connected to the outer side of the connecting ring. The outer side of the telescopic spring 941 is fixedly connected to a slip ring 942. The slip ring 942 is slidably connected to the inner side of the air-containing pipe 93. The outer surface of the gas pipe 93 is connected to the outer side of the slip ring 942, and the connecting frame 943 is fixedly connected at equal intervals. The outer end of the connecting frame 943 is fixedly connected to the piston rod 944, and the piston rod 944 is slidably connected to the inside of the gas pipe 93. The end of the piston rod 944 is fixedly connected to the piston plate 945, and the piston plate 945 is slidably connected to the inside of the gas pipe 93. When the elastic container 9 is working during the use of this device, as the atomized gas and the reaction gas are continuously injected into the tank body 10, the gas pressure in the tank gradually increases. Since the mounting ring 91 is fixed at equal intervals on the outside of the tank body 10, and the gas pipe 93 is connected to the mounting ring 91, the connecting groove 92 is connected to the tank body 10. The interior is connected to the air pipe 93. At this time, the high-pressure gas in the tank enters the air pipe 93 through the connecting groove 92. The gas entering the air pipe 93 pushes the piston plate 945, causing the piston plate 945 to slide along the inner wall of the air pipe 93. The movement of the piston plate 945 drives the piston rod 944 connected thereto. The outer end of the piston rod 944 is connected to the slip ring 942 through the connecting frame 943. The slip ring 942 slides on the outer surface of the air pipe 93 and stretches the telescopic spring 941 at the same time. One end of the telescopic spring 941 is fixed on the connecting ring, and the other end is connected to the slip ring 942. Through the elastic deformation of the telescopic spring 941, the piston plate 945 moves in the air pipe 93 to make more space. The second connecting valve 12 on the exhaust pipe 11 is opened, and the air pressure in the tank drops. The telescopic spring 941 in the stretched state is reset, and the slip ring 942 is pulled, and the piston rod 944 and the piston plate 945 are driven to move inward through the connecting frame 943, pushing the gas in the air pipe 93 back to the tank 10, and assisting in discharging the reacted gas in the tank, thereby realizing the dynamic balance and circulation of the gas between the tank 10 and the elastic container 9, which can better promote the gas reaction, improve the overall gas reaction effect of the device, and further improve the accuracy of subsequent detection of the device.

[0035] The implementation principle of the nebulizer for an inductively coupled plasma emission mass spectrometer in the embodiment of the present application is as follows: during the application of the device, when the nebulizer body 2 is working, the air pump 3 discharges the atomized gas into the interior of the tank body 10 through the pipeline, and then closes the second connecting valve 12 to seal the bottom of the tank body 10 to prevent gas leakage. After the gas is injected, the first connecting valve 4 is closed to block the connection channel between the tank body 10 and the air pump 3. Then, the reaction gas is introduced into the interior of the tank body 10 through the second connecting valve 12; alternatively, the reaction gas and the atomized gas can also be injected into the tank body 10 through the first connecting valve 4 and the third connecting valve 74 respectively at the same time. During the gas injection process, the second connecting valve 12 is always kept closed. As the gas continues to enter, the internal air pressure of the tank body 10 gradually increases. At this time, the gas enters the gas pipe 93 through the connecting groove 92, pushing the piston plate 945 to move outward, making more space in the gas pipe 93, so that the tank body 10 can accommodate more atomized gas and reaction gas;

[0036] When the piston plate 945 moves outward, it pushes the piston rod 944 to move outward synchronously. The piston rod 944 drives the connecting frame 65, causing the slip ring 942 to be displaced and stretching the telescopic spring 941, putting it in a stretched state. At this time, the discharge rod 7324 is started. The operation of the discharge rod 7324 causes the atomized gas and the reaction gas to undergo a chemical reaction. At the same time, the first motor 72 is started to drive the rotating shaft 731 to rotate. The rotating shaft 731 drives the outer reaction plate 732 to rotate. The reaction plate 732 drives the discharge rod 7324 in the inner groove 7322 to rotate together. The rotation of the discharge rod 7324 causes it to continuously reciprocate inside the tank body 10, increasing the contact area and time with the reaction gas and the atomized gas, thereby promoting a full reaction of the gases.

[0037] After the gas reaction is completed, the second connecting valve 12 is opened, and the gas inside the tank body 10 finds a venting channel, the air pressure drops rapidly, and the telescopic spring 941 in the stretched state is reset, pushing the piston rod 944 to drive the piston plate 945 to move inward, and the reacted gas is discharged from the tank body 10 through the second connecting valve 12 and the exhaust pipe 11. During the exhaust process, the driving motor drives the spiral power paddle 75 at the bottom of the rotating shaft 731 to rotate. The spiral power paddle 75 accelerates the flow of gas, so that the gas is discharged from the exhaust pipe 11 more stably and quickly. At the same time, during the process of its gas reaction, the rotating shaft 731 drives the spiral drive paddle to rotate, and its spiral drive paddle can promote gas circulation and improve its gas mixing reaction effect. The device cooperates with the elastic container 9 through the cyclically driven reaction plate 732 to realize the continuous cyclic reaction of the gas, ensuring that the gas inside the tank body 10 is evenly mixed and fully reacted, thereby effectively improving the detection accuracy;

[0038] The second motor 62 is started, and the second motor 62 drives the screw rod 63 to rotate. The screw rod 63 rotates to drive the slider 64 to slide up and down in the vertical rail 61. The sliding of the slider 64 drives the connecting frame 65 to move, thereby driving the sealing cover 71 to move upward, and the mixing mechanism 7 under the sealing cover 71 is pulled out from the inside of the tank body 10, which is convenient for the staff to inspect, clean and repair the inside of the tank body 10 and the mixing mechanism 7. After the inspection is completed, the second motor 62 is started again, the screw rod 63 rotates in the opposite direction, drives the slider 64 to move downward, and the connecting frame 65 pushes the sealing cover 71 to cover the top of the tank body 10 again, so that the bottom of the mixing mechanism 7 is reinserted into the tank body 10. At this time, the first motor 72 is started, which drives the mixing assembly 73 to rotate, and continuously stirs and mixes the materials in the tank body 10 to ensure that the materials are fully reacted, improve the reaction effect, and ensure the accuracy and reliability of subsequent test data.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
