Generally, the determination of the contents of carbon, aluminum, iron, etc. is required. During laser detection, the molten salt will generate smoke due to the too high temperature, and the smoke will block the laser light, resulting in errors in the detection results.

[0008] And a sampling transmission mechanism, which is used to sequentially transport the samples taken from the inside of the reaction kettle to the sample preparation chamber and the detection chamber.

[0014] Further, a first valve is installed at the connecting part between the reaction kettle and the sample preparation chamber, and a second valve is installed at the connecting part between the sample preparation chamber and the detection chamber.
[0015] The beneficial effects of the present utility model: The present utility model uses a sampling transmission mechanism to first cool the molten salt sample obtained in the reaction kettle to form crystals inside the sample preparation chamber to avoid the generation of smoke from the high-temperature molten salt, and then transports the crystalline sample to the detection chamber for detection.

[0020] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.
[0021] As Figure 1 shown, a molten salt sampler is installed on the top of the reaction kettle 1. The reaction kettle 1 has high-temperature molten salt inside and is equipped with a level identification mechanism for identifying the level of the reaction kettle 1. This sampler is used to take out the molten salt sample from the inside of the reaction kettle 1 for detection. The sampler is a fully sealed metal structure, adopting heat insulation and anti-corrosion process design, and includes:
[0022] The sample preparation chamber 2 has a low-temperature sample preparation cavity formed inside it, thus creating a low-temperature environment to cool the samples inside, achieving stable crystallization after reaching the predetermined temperature and avoiding the impact of the smoke generated by high-temperature molten salt on the detection.
[0023] The detection chamber 3 is located above the sample preparation chamber 2 and has a low-temperature detection cavity communicating with the sample preparation cavity. The low-temperature detection cavity creates a low-temperature environment to further inhibit the impact of smoke on the detection and performs laser detection on the crystalline samples from the sample preparation cavity. The detection chamber 3 is provided with a detection window 303 for the laser to enter.
[0024] And the sampling transmission mechanism 4 is used to sequentially transport the samples obtained inside the reactor 1 to the sample preparation chamber 2 and the detection chamber 3. The sampling transmission mechanism 4 includes a driving part 401, a sampling rod 402 connected to the output end of the driving part 401, and a probe plate 403 located at the bottom of the sampling rod 402. The sampling rod 402 is a cylindrical rod, and the probe plate 403 is flat.
[0025] During operation, first, the driving part 401 drives the probe plate 403 to move down below the liquid level of the reactor 1 and stay for a set time to obtain the sample. Then, the driving part 401 drives the probe plate 403 to move up to the sample preparation chamber 2. The low-temperature environment formed by the low-temperature sample preparation cavity crystallizes the sample to avoid the generation of smoke by high-temperature molten salt. Next, the driving part 401 drives the probe plate 403 to continue moving up to the detection chamber 3. The low-temperature environment formed by the detection cavity further inhibits the formation of smoke. At the same time, the detection window 303 is opened and the laser detection mechanism is activated, and the laser enters from the detection window 303 to complete the detection of the sample crystallization.
[0026] In some examples, the sample preparation chamber 2 is provided with a first air inlet 201 for introducing low-temperature compressed air and a first air outlet 202 for discharging air, so as to create a low-temperature environment to cool the samples.
[0027] In some examples, the detection chamber 3 is provided with a second air inlet 301 for introducing low-flow compressed air and a second air outlet 302 for discharging air, so as to create a low-temperature environment to further inhibit the formation of smoke.
[0028] In some examples, the sampler further includes an air compressor station and a tail gas collector. The air outlet of the air compressor station is communicated with the first air inlet 201 and the second air inlet 301. The air compressor station is used to prepare clean compressed air to supply the sample preparation chamber 2 and the detection chamber 3. The compressed air is an inert gas or nitrogen. The tail gas inlet of the tail gas collector is communicated with the first air outlet 202 and the second air outlet 302.
[0029] In some examples, the sampler is magnetically driven and operates without electricity inside to ensure intrinsic safety.
[0030] In some examples, the sampling rod 402 is synthesized from a metal and silicon-based composite material, which is resistant to high temperatures, acids, and alkalis. The probe plate 403 is made of a silicon-based composite material, and the sample preparation chamber 2, the detection chamber 3, and the opening and closing mechanism are all made of silicon-based composite materials.
[0031] In some examples, a first valve is installed at the connecting part between the reaction kettle 1 and the sample preparation chamber 2, and a second valve is installed at the connecting part between the sample preparation chamber 2 and the detection chamber 3.
[0032] Working principle:
[0033] Each actuator works according to the timing set by the program, sends out an instruction to start sampling, opens the first valve between the sample preparation chamber 2 and the reaction kettle 1, and closes the connections between the sample preparation chamber 2 and other devices. The sampling transmission mechanism 4 works, the probe plate 403 moves below the liquid level of the reaction kettle 1, stays for a set time, returns the probe plate 403 to the sample preparation chamber 2, and after the sample crystallizes according to the timing of the sample preparation chamber 2, the sample is transferred to the detection chamber 3, and the sample is detected according to the timing of the detection chamber 3, and the system is reset to prepare for the next detection.
[0034] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
