Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-salt samples, and particularly to a high-salt sample bubbler for a spectrometer. Background Art
[0002] The injection system is a very important system in an ICP spectrometer. The stability and repeatability of the injection system directly affect the stability and repeatability of the whole ICP spectrometer. The main function of the injection system is to introduce the sample to be measured into the nebulizer and the spray chamber in a liquid state to form a uniform aerosol. Subsequently, the aerosolized sample to be measured is discharged out of the spray chamber through a pipeline for plasma generation.
[0003] Regarding the above related technologies, the inventor believes that there are the following defects: when the sample to be measured enters the nebulizer, due to the instability of the internal plasma, the sample is blocked in the nebulizer, resulting in the sample flowing back into the sample to be measured and mixing with the sample to be measured. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a high-salt sample bubbler for a spectrometer.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a high-salt sample bubbler for a spectrometer, including a sample bottle, a first connecting pipe is connected to the upper end of the sample bottle, the other end of the first connecting pipe far away from the sample bottle is connected to a nebulizer, the end of the nebulizer far away from the first connecting pipe is connected to a spray chamber, a discharge pipe is connected to the nebulizer, and a first bubbling device for dredging the nebulizer is arranged on the nebulizer.
[0006] By adopting the above technical solutions, when the injection system is in use, the staff needs to pass the sample liquid in the sample bottle into the nebulizer through the first connecting pipe. Subsequently, the sample liquid enters the spray chamber through the nebulizer, so that the sample liquid forms an aerosol in the spray chamber. Subsequently, the aerosolized sample is discharged out of the spray chamber through the discharge pipe for plasma generation. During this process, the staff needs to start the first bubbling device, thereby reducing the probability of the nebulizer being blocked.
[0007] Further, the first bubbling device includes a bubbler, an air inlet pipe connected to the bubbler, and an air outlet pipe connected to the bubbler. The end of the air outlet pipe far away from the bubbler is communicated with the nebulizer.
[0008] Further, the bubbler includes a bubbling bottle, a gas guide pipe connected to the bubbling bottle, and a gas spray pipe connected to the bubbling bottle. The end of the air outlet pipe far away from the nebulizer is communicated with the gas spray pipe. The air inlet pipe is communicated with the gas guide pipe. The gas guide pipe extends into the bubbling bottle. Air outlet holes are formed in the gas guide pipe. The bubbling bottle is filled with pure water.
[0009] By adopting the above technical solution, when the sampling system is in use, the staff needs to input inert gas (usually argon) into the foaming bottle through the inlet pipe, and then the inert gas enters the inside of the foaming bottle through the air guide pipe, and then is discharged through the air outlet holes to mix the inert gas with pure water, and then the pure water wets the inert gas. Subsequently, the wetted inert gas moves to the atomizer through the spray pipe and the outlet pipe, and then the wetted argon is mixed with the sample liquid, so as to ensure the stability of the plasma in the sample liquid, and then reduce the probability of blockage of the atomizer.
[0010] Furthermore, a backflow prevention device is provided on the first connecting pipe. The backflow prevention device includes a connecting member installed on the first connecting pipe. A through hole is penetrated through the side wall of the connecting member, and the through hole is communicated with the first connecting pipe. The backflow prevention device further includes a fixing plate fixedly arranged on the inner wall of the through hole and a rotating plate rotatably arranged in the through hole. The side wall of the rotating plate away from the atomizer abuts against the side wall of the fixing plate close to the atomizer.
[0011] By adopting the above technical solution, when the sample liquid passes through the connecting member, the rotating plate rotates under the action of the sample liquid, so that the sample liquid flows into the atomizer. During this process, when the atomizer is blocked, the sample liquid cannot flow into the atomizer. At this time, since the side wall of the rotating plate away from the atomizer abuts against the side wall of the fixing plate close to the atomizer, the rotating plate abuts against the side wall of the fixing plate under the action of the pressure difference. At this time, the sample liquid cannot flow in, and then the probability of backflow of the sample liquid is reduced.
[0012] Furthermore, a rotating groove is provided on the inner wall of the through hole, and a rotating rod is rotatably arranged in the rotating groove. The rotating rod is fixedly connected with the rotating plate.
[0013] By adopting the above technical solution, when the rotating plate rotates, the rotating rod rotates under the action of the rotating plate. During this process, the rotating rod rotates in the rotating groove, so as to limit the rotating plate, and then reduce the probability of shaking of the rotating plate during rotation, and then improve the stability of the device.
[0014] Furthermore, a reset groove is provided on the inner wall of the rotating groove, and a torsion spring is fixedly arranged on the side wall of the rotating rod. The other end of the torsion spring is fixedly arranged on the inner wall of the reset groove.
[0015] By adopting the above technical solution, when the transmission of the sample liquid stops, the rotating rod resets under the action of the torsion spring, and then the rotating plate resets under the action of the rotating rod, so as to reduce the difficulty of the staff in resetting the rotating plate, and then reduce the working difficulty of the staff.
[0016] Furthermore, a second bubbler device is connected to the intake pipe. The intake pipe communicates with the jet pipe of the second bubbler device, and the bubbler communicates with the air guide pipe of the second bubbler device through a second connecting pipe.
[0017] By adopting the above technical solution, the second bubbler device reduces the probability of backflow of pure water in the first bubbler device.
[0018] In summary, the present utility model has the following beneficial effects:
[0019] 1. In this application, when the sampling system is in use, the staff needs to pass the sample liquid in the sample bottle into the atomizer through the first connecting pipe. Subsequently, the sample liquid enters the atomization chamber through the atomizer, and then the sample liquid forms an aerosol in the atomization chamber. Subsequently, the aerosolized sample is discharged from the atomization chamber through the discharge pipe for plasma treatment. During this process, the staff needs to activate the first bubbling device, thereby reducing the probability of blockage of the atomizer;
[0020] 2. In this application, when the sampling system is in use, the staff needs to input an inert gas (usually argon) into the bubbling bottle through the intake pipe, so that the inert gas enters the inside of the bubbling bottle through the air guide pipe, and then is discharged through the air outlet holes to mix with the pure water, so that the pure water wets the inert gas. Subsequently, the wetted inert gas moves to the atomizer through the jet pipe and the air outlet pipe, so that the wetted argon is mixed with the sample liquid, thereby ensuring the stability of the plasma in the sample liquid and reducing the probability of blockage of the atomizer;
[0021] 3. In this application, when the sample liquid passes through the connecting piece, the rotating plate rotates under the action of the sample liquid, so that the sample liquid flows into the atomizer. During this process, when the atomizer is blocked, the sample liquid cannot flow into the atomizer. At this time, since the side wall of the rotating plate away from the atomizer abuts against the side wall of the fixing plate close to the atomizer, the rotating plate abuts against the side wall of the fixing plate under the action of the pressure difference. At this time, the sample liquid cannot flow in, thereby reducing the probability of backflow of the sample liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0028] As Figures 1-4 shown, the high-salt sample foamer of the spectrometer disclosed in the embodiment of the present application includes a sample bottle 1, a first connecting pipe 11, an atomizer 12, an atomization chamber 13, a discharge pipe 14, a first foaming device 2, an anti-backflow device 4, a rotating rod 5 and a torsion spring 6. The first connecting pipe 11 is of a circular tubular structure, and the first connecting pipe 11 is connected to the upper end of the sample bottle 1. The atomizer 12 is connected to the other end of the first connecting pipe 11 away from the sample bottle 1, and the atomization chamber 13 is connected to the end of the atomizer 12 away from the first connecting pipe 11. The discharge pipe 14 is of a circular tubular structure, and the discharge pipe 14 is connected to the atomizer 12.
[0029] When the sampling system is in use, the staff needs the sample liquid in the sample bottle 1 to enter the atomizer 12 through the first connecting pipe 11. Subsequently, the sample liquid enters the atomization chamber 13 through the atomizer 12, so that the sample liquid forms an aerosol shape in the atomization chamber 13. Subsequently, the aerosolized sample is discharged from the atomization chamber 13 through the discharge pipe 14 for plasma treatment. During this process, the staff needs to start the first foaming device 2, thereby reducing the probability of blockage of the atomizer 12.
[0030] The first foaming device 2 is arranged on the atomizer 12 and is used to dredge the atomizer 12. The first foaming device 2 includes a foamer 21, an air inlet pipe 22 and an air outlet pipe 23. The air inlet pipe 22 is of a circular tubular structure, and the air inlet pipe 22 is connected to the foamer 21. The air outlet pipe 23 is of a circular tubular structure, and the air outlet pipe 23 is connected to the foamer 21. The end of the air outlet pipe 23 away from the foamer 21 is communicated with the atomizer 12.
[0031] The bubbler 21 includes a bubbling bottle 211, an air guide tube 212, and a jet tube 213. The bubbling bottle 211 is filled with pure water. The air guide tube 212 is connected to the bubbling bottle 211. The intake pipe 22 is in communication with the air guide tube 212. The air guide tube 212 extends into the bubbling bottle 211, and air holes 3 are formed in the air guide tube 212. The jet tube 213 is connected to the bubbling bottle 211. One end of the outlet pipe 23 away from the atomizer 12 is in communication with the jet tube 213.
[0032] When the sampling system is in use, the staff needs to input an inert gas (usually argon) into the bubbling bottle 211 through the intake pipe, so that the inert gas enters the inside of the bubbling bottle 211 through the air guide tube 212, and then is discharged through the air holes 3 to mix the inert gas with the pure water, so that the pure water wets the inert gas. Subsequently, the wetted inert gas moves through the jet tube 213 and the outlet pipe 23 into the atomizer 12, so that the wetted argon is mixed with the sample liquid, thereby ensuring the stability of the plasma in the sample liquid and reducing the probability of blockage of the atomizer 12.
[0033] The anti-backflow device 4 is arranged on the first connecting pipe 11. The anti-backflow device 4 includes a connecting piece 41, a fixing plate 42, and a rotating plate 43. The connecting piece 41 is installed on the first connecting pipe 11. A through hole 31 is formed through the side wall of the connecting piece 41, and the through hole 31 is in communication with the first connecting pipe 11. The fixing plate 42 is fixedly arranged on the inner wall of the through hole 31. The rotating plate 43 is rotatably arranged in the through hole 31, and the side wall of the rotating plate 43 away from the atomizer 12 abuts against the side wall of the fixing plate 42 close to the atomizer 12.
[0034] When the sample liquid passes through the connecting piece 41, the rotating plate 43 rotates under the action of the sample liquid, so that the sample liquid flows into the atomizer 12. During this process, when the atomizer 12 is blocked, the sample liquid cannot flow into the atomizer 12. At this time, since the side wall of the rotating plate 43 away from the atomizer 12 abuts against the side wall of the fixing plate 42 close to the atomizer 12, the rotating plate 43 abuts against the side wall of the fixing plate 42 under the action of the pressure difference. At this time, the sample liquid cannot flow in, thereby reducing the probability of backflow of the sample liquid.
[0035] A rotating groove 32 is formed on the inner wall of the through hole 31. The rotating rod 5 is in a round rod shape and its axis is horizontal. The rotating rod 5 is rotatably arranged in the rotating groove 32, and the rotating rod 5 is fixed to the rotating plate 43.
[0036] When the rotating plate 43 rotates, the rotating rod 5 rotates under the action of the rotating plate 43. During this process, the rotating rod 5 rotates in the rotating groove 32, so that the rotating rod 5 limits the rotating plate 43, thereby reducing the probability of shaking of the rotating plate 43 during rotation and improving the stability of the device.
[0037] A reset groove 33 is formed in the inner wall of the rotating groove 32. One end of the torsion spring 6 is fixedly arranged on the side wall of the rotating rod 5, and the other end of the torsion spring 6 is fixedly arranged on the inner wall of the reset groove 33.
[0038] When the sample liquid stops being transmitted, the rotating rod 5 is reset under the action of the torsion spring 6, and then the rotating plate 43 is reset under the action of the rotating rod 5, thereby reducing the difficulty for the staff to reset the rotating plate 43, and further reducing the working difficulty of the staff.
[0039] In order to reduce the probability of backflow of pure water in the first bubbler 21 device, a second bubbler 21 device is connected to the air inlet pipe 22. The air inlet pipe 22 is in communication with the air jet pipe 213 of the second bubbler 21 device. The bubbler 21 is in communication with the air guide pipe 212 of the second bubbler 21 device through the second connecting pipe 71. The second bubbler 21 device reduces the probability of backflow of pure water in the first bubbler 21 device.
[0040] The working principle of the high-salt sample bubbler of the spectrometer in this embodiment is as follows: When the sampling system is in use, the staff needs to pass the sample liquid in the sample bottle 1 into the atomizer 12 through the first connecting pipe 11. Subsequently, the sample liquid enters the atomization chamber 13 through the atomizer 12, and then the sample liquid forms an aerosol in the atomization chamber 13. Subsequently, the aerosolized sample is discharged from the atomization chamber 13 through the discharge pipe 14 for plasma treatment. During this process, when the sampling system is in use, the staff needs to input an inert gas (usually argon) into the bubbling bottle 211 through the inlet pipe, and then the inert gas enters the interior of the bubbling bottle 211 through the air guide pipe 212, and then is discharged through the air outlet hole 3 to mix the inert gas with pure water, and then the pure water wets the inert gas. Subsequently, the wetted inert gas moves to the atomizer 12 through the air jet pipe 213 and the air outlet pipe 23, and then the wetted argon is mixed with the sample liquid, thereby ensuring the stability of the plasma in the sample liquid and further reducing the probability of blockage of the atomizer 12.
[0041] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
