Description

Technical Field

[0001] The invention relates to the technical field of cyclone mist chamber structures, in particular to a cyclone mist chamber with a liquid accumulation monitoring function. Background Art

[0002] The cyclonic spray chamber is a basic component of the sample introduction system, which allows the sample to enter the nebulizer chamber in the form of an aerosol, and then the sample in the form of an aerosol is sent to the ICP matrix tube at the rear station through the outlet of the nebulizer chamber for subsequent testing. The existing cyclonic spray chamber generally only has a waste channel at the bottom of the nebulizer, so that the residual sample condenses into water droplets and is discharged through the waste channel below the nebulizer. However, in actual use, the waste channel may be blocked, resulting in the accumulation of liquid formed by the residual sample, which is eventually discharged from the outlet of the nebulizer, resulting in The ICP flameout may even cause the torch and high-frequency coil at the rear workstation to burn out. Therefore, in order to reliably monitor whether there is liquid accumulation in the atomization chamber, the existing cyclone spray chambers are all made of transparent glass, and the outside cannot be covered with an insulating shell, which makes the aerosol in the atomization chamber not insulated, and then the aerosol will liquefy quickly, and the aerosol sample in the cyclone spray chamber cannot form a reliable and stable cyclone, resulting in relatively few samples actually effectively transported into the ICP torch, and most of the samples are discharged after being liquefied. Therefore, it is urgent to develop a cyclone spray chamber that can fully and reliably transport samples. Summary of the invention

[0003] In view of the above problems, the present invention provides a cyclonic spray chamber with a liquid accumulation monitoring function, which can reliably monitor the liquid accumulation in the nebulizer chamber and ensure the atomization temperature of the nebulizer chamber, thereby ensuring that the cyclonic flow stably and reliably flows through the nebulizer chamber outlet into the ICP torch tube at the rear, ensuring that the sample is fully and reliably utilized.

[0004] A cyclonic mist chamber with a liquid accumulation monitoring function, characterized in that it comprises:

[0005] The cyclonic spray chamber body includes an atomization chamber, an atomization chamber inlet pipeline, an atomization chamber outlet pipeline, a waste liquid discharge outlet, and a liquid level sensor connection port;

[0006] Liquid level sensor;

[0007] Nebulizer;

[0008] Encapsulate the cavity;

[0009] and waste liquid outflow pipeline;

[0010] The outer periphery of the atomization chamber is coated with the wrapping cavity, and the wrapping cavity is respectively provided with corresponding avoidance notches corresponding to the atomization chamber inlet pipeline, the atomization chamber outlet pipeline, the waste liquid discharge outlet, and the liquid level sensor connection port. The atomization chamber inlet pipeline is located at a convex side of the center offset of the atomization chamber, and a connecting joint is sleeved on the front end of the atomization chamber inlet pipeline. The output pipe of the atomizer is inserted into the inner cavity of the connecting joint. An upwardly convex atomization chamber outlet pipeline is arranged at the top center position of the atomization chamber. The atomization chamber inlet pipeline, the atomization chamber outlet pipeline, and the atomization chamber are made as a whole. A liquid level sensor connection port is arranged at the middle and upper part of the height direction of the atomization chamber. The liquid level sensor is inserted into the liquid level sensor connection port and is sealed. The output end of the liquid level sensor is externally connected to an external signal controller through a connecting line. A waste liquid discharge outlet is arranged at the bottom center position of the atomization chamber, and the inner end of the waste liquid outflow pipeline is inserted into the waste liquid discharge outlet and is sealed.

[0011] It is further characterized in that: the wrapping cavity is formed by combining an upper wrapping shell and a lower wrapping shell, and the positions of the upper wrapping shell and the lower wrapping shell that contact the atomizer, the atomization chamber inlet pipeline, and the atomization chamber outlet pipeline are all made of flexible materials, which ensures that the cyclonic spray chamber body is not easily damaged;

[0012] The upper and lower wrapping shells are provided with mounting holes at their four corners and are connected by connecting bolts to form a wrapping cavity.

[0013] The atomization chamber comprises an upper conical cavity, a middle cylindrical cavity and a lower conical cavity, wherein the upper conical cavity is a conical cavity closing from the upper circular edge of the middle cylindrical cavity from bottom to top, the middle cylindrical cavity is a cylindrical cavity with a set height, and the lower conical cavity is a conical cavity closing from the lower circular edge of the middle cylindrical cavity from top to bottom;

[0014] A tangentially inserted atomization chamber inlet pipeline is connected to a side wall of the middle part of the middle cylindrical cavity in the height direction, and a nebulization chamber outlet pipeline is arranged at the top center of the upper conical cavity, so that the aerosol sample fully swirls along the middle cylindrical cavity and the upper conical cavity before flowing out through the nebulization chamber outlet pipeline;

[0015] The waste liquid discharge port is arranged at the bottom center of the lower conical body cavity, so that the accumulated liquid can be discharged reliably;

[0016] The liquid level sensor connection port is provided at the middle upper part of the height direction of the middle cylindrical cavity, and the liquid level sensor connection port is sealed and connected to the liquid level sensor. The sensing end of the liquid level sensor extends inwardly into the inner cavity of the atomizing chamber, which does not affect the cyclonic operation. When the accumulated liquid contacts the sensing part of the liquid level sensor, the liquid level sensor sends a signal to the signal sensor, and the operator suspends the operation of the cyclonic atomizing chamber and performs the operation of cleaning the accumulated liquid.

[0017] The cavity formed by assembling the upper wrapping shell and the lower wrapping shell is shaped like the atomizing chamber. The upper wrapping shell and the lower wrapping shell are made of heat-insulating materials to ensure a reliable working temperature of the atomizing chamber.

When the accumulated liquid exceeds the monitoring position of the liquid level sensor, the feedback signal is transmitted to the signal controller of the liquid level sensor, and the signal controller transmits the liquid level monitoring signal and feeds it back to the main control system of the equipment to achieve the function of monitoring the accumulated liquid. At the same time, because it has the function of monitoring the accumulated liquid, the atomization chamber of the cyclone spray chamber body does not need to be exposed to the air, and then the outer periphery of the atomization chamber is coated with a wrapping cavity, and the wrapping cavity is respectively provided with corresponding avoidance gaps corresponding to the atomization chamber inlet pipeline, the atomization chamber outlet pipeline, the waste liquid discharge outlet, and the liquid level sensor connection port, which enables the aerosol in the atomization chamber to have a reliable atomization temperature, ensuring that the aerosol cyclone is stable and reliable. Then, the aerosol flows into the ICP torch tube at the rear through the atomization chamber outlet, ensuring that the sample is fully and reliably utilized. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The cyclonic spray chamber body 10 includes an atomization chamber 11, an atomization chamber inlet pipeline 12, an atomization chamber outlet pipeline 13, a waste liquid outlet 14, and a liquid level sensor connection port 15;

[0028] The outer periphery of the atomizing chamber 11 is covered with a wrapping cavity 40, and the wrapping cavity 40 is respectively provided with corresponding avoidance notches corresponding to the atomizing chamber inlet pipeline 12, the atomizing chamber outlet pipeline 13, the waste liquid discharge outlet 14, and the liquid level sensor connection port 15. The atomizing chamber inlet pipeline 12 is located at a convex side of the center offset of the atomizing chamber 11, and the front end of the atomizing chamber inlet pipeline 12 is sleeved with a connecting joint 121. The output pipe 31 of the atomizer 30 is inserted into the inner cavity of the connecting joint 121. The top center position of the atomizing chamber 11 is provided with an upwardly convex atomizing chamber outlet pipe. The atomizing chamber 11 is made of transparent glass by integrally sintering. A liquid level sensor connection port 15 is provided at the middle and upper part of the height direction of the atomizing chamber 11. The liquid level sensor 20 is inserted into the liquid level sensor connection port 15 and is sealed. The output end of the liquid level sensor 20 is connected to an external signal controller through a connecting line 21. A waste liquid discharge port 14 is provided at the bottom center of the atomizing chamber 11. The inner end of the waste liquid outflow pipeline 50 is inserted into the waste liquid discharge port 14 and is sealed.

[0029] In a specific embodiment, the wrapping cavity 40 is formed by combining an upper wrapping shell 41 and a lower wrapping shell 42. The upper wrapping shell 41 and the lower wrapping shell 42 contacting the atomizer 11, the atomization chamber inlet pipe 12, and the atomization chamber outlet pipe 13 are all made of flexible materials, which ensures that the cyclonic spray chamber body 10 is not easily damaged;

[0030] The upper and lower wrapping shells 41 and 42 are provided with mounting holes 43 at their four corners, and are connected by connecting bolts to form a wrapping cavity 40;

[0031] The atomization chamber 11 includes an upper conical cavity 111, a middle cylindrical cavity 112, and a lower conical cavity 113.

[0033] A waste liquid outlet 14 is provided at the bottom center of the lower conical body cavity 113, which enables the accumulated liquid to be discharged reliably;

[0034] A liquid level sensor connection port 15 is provided in the middle and upper part in the height direction of the middle cylindrical cavity 112, and the liquid level sensor connection port 15 is sealed and connected with a liquid level sensor 20.

[0037] Its working principle is as follows: by setting a liquid level sensor connection port in the height direction of the atomization chamber, the liquid level sensor can be reliably inserted, and the liquid level sensor is connected to an external signal controller through a connecting line. When the accumulated liquid exceeds the monitoring position of the liquid level sensor, the feedback signal is transmitted to the signal controller of the liquid level sensor, and the signal controller transmits the liquid level monitoring signal back to the main control system of the equipment to achieve the function of monitoring the accumulated liquid. At the same time, because it has the function of monitoring the accumulated liquid, the atomization chamber of the cyclone spray chamber body does not need to be exposed to the air, and then the outer periphery of the atomization chamber is coated with a wrapping cavity, and the wrapping cavity is respectively provided with corresponding avoidance gaps corresponding to the atomization chamber inlet pipeline, the atomization chamber outlet pipeline, the waste liquid discharge outlet, and the liquid level sensor connection port, which enables the aerosol in the atomization chamber to have a reliable atomization temperature, ensuring that the aerosol cyclone is stable and reliable. Then the aerosol flows into the ICP torch tube at the rear through the atomization chamber outlet, ensuring that the sample is fully and reliably utilized.
