Description

Technical Field

[0001] This invention relates to the field of reactor sampling technology, and in particular to a ternary precursor reactor sampling and detection system. Background Technology

[0002] The ternary precursor material is nickel-cobalt-manganese hydroxide (NixCoyMn(1-xy)(OH)2). The ternary composite cathode material precursor product uses nickel salt, cobalt salt, and manganese salt as raw materials, and the ratio of nickel, cobalt, and manganese can be adjusted according to actual needs.

[0003] During the processing, it is necessary to sample and test the raw materials in the reactor. The particle size in the reactor is an important parameter for judging whether the reaction process is normal. Therefore, the accuracy and timeliness of the particle size test results are required. At present, it is generally necessary to manually sample and send the samples to the laboratory for testing. From sampling, sample delivery, testing to result sharing, it usually takes 30 minutes to an hour or even longer, which cannot achieve real-time testing and the test results have a certain lag.

[0004] Therefore, there is an urgent need for a ternary precursor reactor sampling and testing system to solve the problem that the test results are delayed due to manual sampling and testing in the existing technology, which affects production efficiency. Summary of the Invention

The sampling tube extends along the height direction of the reactor and is connected to the interior of the reactor. The sampling element is built into the sampling tube and is used to extract samples from the bottom of the reactor.

[0010] A detector, spaced apart from the reaction vessel, is used to detect samples; and

[0011] The second sampling component includes a peristaltic pump, the inlet of which is connected to the interior of the sampling tube and the outlet of which is connected to the inner wall of the detector, for sampling or recovering samples.

[0012] In some embodiments, the sampling tube is vertically arranged and has a temporary storage chamber and a sampling chamber arranged sequentially from top to bottom. The feed end of the peristaltic pump is connected to the interior of the temporary storage chamber. The sampling element is built into the temporary storage chamber and the sampling chamber to allow the sample to move between the sampling chamber and the temporary storage chamber.

[0013] In some embodiments, the sampling component includes a rotating shaft, a first helical blade, and a drive motor.

The first helical blade is built into the sampling chamber and fixedly sleeved on the rotating shaft. The fixed end of the drive motor is connected to the sampling tube, and the output shaft is connected to the rotating shaft.

[0014] In some embodiments, the drive motor is capable of rotating in the forward or reverse direction about the axis of its output shaft.

[0015] In some embodiments, the sampling element further includes a second helical blade, which is disposed at a distance from the first helical blade in the temporary storage chamber and is fixedly sleeved on the rotating shaft.

[0016] In some embodiments, the second sampling assembly further includes a first hose, a second hose, and a first valve. The first hose is disposed between the sampling tube and the peristaltic pump, with one end of the first hose connected to the interior of the temporary storage chamber and the other end connected to the feed end of the peristaltic pump. The second hose is disposed between the detector and the peristaltic pump, with one end of the second hose connected to the interior of the detector and the other end connected to the discharge end of the peristaltic pump.

At the same time, the feed end of the peristaltic pump is connected to the sampling tube and the discharge end is connected to the inside of the detector, which is used to transport the sample to the detector to complete the detection, or to recover the remaining sample after the detection is completed back into the reactor. Compared to existing technologies, by setting up a first sampling component and a peristaltic pump, the first sampling component extracts the material from the bottom of the reactor to the top of the sampling tube, and then the peristaltic pump uses the thrust generated to transport the sample to the detector for testing. At the same time, the peristaltic pump can also generate reverse thrust to recover the remaining sample after testing back to the sampling tube. The sampling component is used to recover the sample, avoiding material waste. This solves the technical problem in existing technologies where manual sampling and testing results have a certain lag, which affects production efficiency. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] To address the technical problem in existing technologies where manual sampling and testing results are subject to delays, thus affecting production efficiency, this invention provides a sampling and testing system for a ternary precursor reactor 1. This system enables automatic sampling, testing, and detection of materials. Simultaneously, it recovers any remaining samples after testing into the sampling tube 21 and uses the sampling element 22 to collect the samples, thus avoiding material waste.

[0051] It should be noted that the ternary precursor reactor 1 sampling and detection system described in this invention is used in, but not limited to, the field of reactor 1 sampling technology. For ease of explanation, this invention will only use the application of the ternary precursor reactor 1 sampling and detection system in the field of reactor 1 sampling technology as an example. The principle of the ternary precursor reactor 1 sampling and detection system applied to other types of equipment is essentially the same as that applied to the field of reactor 1 sampling technology, and will not be described in detail here.

[0052] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of a sampling and detection system for a ternary precursor reactor 1 according to an embodiment of the present invention. The ternary precursor reactor 1 sampling and detection system includes: reactor 1, first sampling component 2, detector 3, and second sampling component 4. The first sampling component 2 includes a sampling tube 21 and a sampling element 22. The sampling tube 21 extends along the height direction of the reactor 1 and is connected to the interior of the reactor 1. The sampling element 22 is built into the sampling tube 21 and is used to extract samples from the bottom of the reactor 1. The detector 3 is spaced apart from the reactor 1 and is used to detect samples. The second sampling component 4 includes a peristaltic pump 41. The inlet end of the peristaltic pump 41 is connected to the interior of the sampling tube 21, and the outlet end is connected to the inner wall of the detector 3 and is used to sample or recover samples.

[0053] In this device, the first sampling component 2 includes a sampling tube 21 and a sampling element 22. The sampling tube 21 extends along the height direction of the reactor 1 and is built into the reactor 1. The sampling element 22 is built into the sampling tube 21 and is used to draw the sample from the bottom of the reactor 1 to the top of the sampling tube 21. At the same time, the feed end of the peristaltic pump 41 is connected to the sampling tube 21 and the discharge end is connected to the inside of the detector 3, which is used to transport the sample to the detector 3 to complete the detection, or to recover the remaining sample after the detection is completed back into the reactor 1.

[0054] Compared to existing technologies, by setting up a first sampling component 2 and a peristaltic pump 41, the material at the bottom of the reactor 1 is extracted by the first sampling component 2 and brought to the top of the sampling tube 21. Then, the peristaltic pump 41 uses its thrust to transport the sample to the detector 3 for testing. At the same time, the peristaltic pump 41 can also generate a reverse thrust to recover the remaining sample after testing to the sampling tube 21. The sampling component 22 is used to recover the sample, avoiding material waste. This solves the technical problem in existing technologies where manual sampling and testing results are delayed, thus affecting production efficiency.

[0055] Furthermore, the peristaltic pump 41 and the detector 3 in this device are common and readily available equipment on the market. This is a conventional setup known to those skilled in the art and will not be described in detail here.

[0056] In this embodiment, the sampling tube 21 is vertically arranged and has a temporary storage chamber 211 and a sampling chamber 212 arranged sequentially from top to bottom. The feed end of the peristaltic pump 41 is connected to the interior of the temporary storage chamber 211. The sampling element 22 is built into the temporary storage chamber 211 and the sampling chamber 212 to make the sample move between the sampling chamber 212 and the temporary storage chamber 211.

[0057] The sample can move between the temporary storage chamber 211 and the sampling chamber 212, so that the sample can be recycled after the test is completed, effectively reducing material waste and saving production costs.

[0058] In one embodiment, please refer to Figure 2 , Figure 3 The sampling component 22 includes a rotating shaft 221, a first spiral blade 222, and a drive motor 223. The rotating shaft 221 is coaxially arranged with the sampling tube 21 and is rotatably built into the sampling tube 21. The first spiral blade 222 is built into the sampling chamber 212 and is fixedly sleeved on the rotating shaft 221. The fixed end of the drive motor 223 is connected to the sampling tube 21, and the output shaft is connected to the rotating shaft 221.

[0059] The rotation of the drive motor 223 drives the rotating shaft 221 and the first spiral blade 222 to rotate relative to the sampling tube 21, which enables the sample to move in a specified direction and allows the sample at the bottom of the reactor 1 to be lifted above the sampling tube 21 and temporarily stored in the temporary storage chamber 211, waiting for the next operation.

[0060] Furthermore, the rotating shaft 221, the first spiral blade 222, and the drive motor 223 form a structure similar to a screw feeder, which will not be described in detail here.

[0061] In this embodiment, the drive motor 223 can rotate in the forward or reverse direction around the axis of its output shaft.

[0062] By driving the motor 223 to rotate forward and reverse, the extraction and recovery of samples can be achieved.

[0063] Furthermore, the drive motor 223 here is a common and readily available forward and reverse motor on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0064] One implementation method is, for example Figure 3 As shown, the sampling component 22 also includes a second helical blade 224, which is disposed at a distance from the first helical blade 222 in the temporary storage chamber 211 and is fixedly sleeved on the rotating shaft 221.

[0065] The second helical blade 224 is spaced apart from the first helical blade 222 and is built into the temporary storage chamber 211, which can improve the recovery rate of the sample in the temporary storage chamber 211 during recycling and reduce material waste.

[0066] In this embodiment, as Figure 1 As shown, the second sampling assembly 4 also includes a first hose 42, a second hose 43 and a first valve 44, a third hose 45 and a second valve 46, a fourth hose 47 and a third valve 48, a fifth hose 49 and a fourth valve 410, and a fifth valve 411.

[0067] The first hose 42 is disposed between the sampling tube 21 and the peristaltic pump 41, with one end of the first hose 42 connected to the interior of the temporary storage chamber 211 and the other end connected to the feed end of the peristaltic pump 41. The second hose 43 is disposed between the detector 3 and the peristaltic pump 41, with one end of the second hose 43 connected to the interior of the detector 3 and the other end connected to the discharge end of the peristaltic pump 41. The first valve 44 is provided with the second hose 43 to connect the interior of the detector 3 to the discharge end of the peristaltic pump 41.

[0068] The first hose 42 is used to connect the peristaltic pump 41 and the sampling tube 21, the second hose 43 is used to connect the peristaltic pump 41 and the detector 3, and the first valve 44 is used to control the discharge of the second hose 43.

[0069] In one embodiment, please refer to Figure 1 The third hose 45 is disposed between the peristaltic pump 41 and the first valve 44, and one end of the third hose 45 is connected to the second hose 43 and the other end is connected to the external environment. The second valve 46 is disposed on the third hose 45.

[0070] The third hose 45 is used to connect the external environment with the peristaltic pump 41. When the second valve 46 is opened, the peristaltic pump 41 can work to recover the remaining sample in the hose into the reactor 1.

[0071] In one embodiment, please refer to Figure 1 The fourth hose 47 is located between the third hose 45 and the first valve 44, with one end of the fourth hose 47 connected to the second hose 43 and the other end connected to an external water source. The third valve 48 is located on the fourth hose 47.

[0072] The fourth hose 47 is used to connect the external water source with the peristaltic pump 41. When the third valve 48 is opened, the peristaltic pump 41 can introduce the external water source into the hose and clean the residual sample inside the hose.

[0073] In one embodiment, please refer to Figure 1 The fifth hose 49 is located between the peristaltic pump 41 and the third hose 45, with one end of the fifth hose 49 connected to the second hose 43 and the other end connected to another peristaltic pump 41. The fourth valve 410 is located on the fifth hose 49.

[0074] The fifth hose 49 and the fourth valve 410 are used to connect multiple reactors 1 and the detector 3, so that one detector 3 can detect samples in multiple reactors 1, improve production efficiency and save production costs.

[0075] Furthermore, the first hose 42, the second hose 43, the third hose 45, the fourth hose 47, and the fifth hose 49 are all common and readily available materials on the market, used in conjunction with the peristaltic pump 41. This is a conventional setup known to those skilled in the art and will not be described in detail here.

[0076] In one embodiment, please refer to Figure 1 The fifth valve 411 is located between the peristaltic pump 41 and the fifth hose 49, and is connected to the second hose 43.

[0077] The fifth valve 411 is used to assist the first valve 44, the second valve 46, the third valve 48 and the fourth valve 410 in precisely controlling the function of the peristaltic pump 41 and improving the stability of the device operation.

[0078] Furthermore, the first valve 44, the second valve 46, the third valve 48, the fourth valve 410, and the fifth valve 411 are all common and readily available materials on the market, used in conjunction with the peristaltic pump 41. This is a conventional setup known to those skilled in the art, and will not be described in detail here.

[0079] To better understand this invention, the following is combined with... Figures 1 to 3 The technical solution of the present invention will be described in detail below:

[0080] The specific workflow of this invention is as follows: The first sampling component 2 includes a sampling tube 21 and a sampling element 22. The sampling tube 21 extends along the height direction of the reactor 1 and is built into the reactor 1. The sampling element 22 is built into the sampling tube 21, used to extract the sample from the bottom of the reactor 1 to the top of the sampling tube 21. Simultaneously, the inlet end of the peristaltic pump 41 is connected to the sampling tube 21, and the outlet end is connected to the inside of the detector 3, used to transport the sample to the detector 3 for testing, or to recover the remaining sample after testing back into the reactor 1. Compared with the prior art, by setting the first sampling component 2 and the peristaltic pump 41, the first sampling component 2 extracts the material from the bottom of the reactor 1 to the top of the sampling tube 21, and then the peristaltic pump 41 uses its thrust to transport the sample to the detector 3 for testing. Simultaneously, the peristaltic pump 41 can also generate a reverse thrust to recover the remaining sample after testing back to the sampling tube 21, and the sampling element 22 is used to recover the sample, avoiding material waste.

[0081] When sampling and testing are required during use, the drive motor 223 first works, driving the first spiral blade 222 to rotate, so that the sample at the bottom of the reactor 1 is transported to the temporary storage chamber. The drive motor 223 stops working, and then the peristaltic pump 41 works to open the first valve 44 and the fifth valve 411, and close the other valves. The slurry sample enters the detector 3, and the detector 3 uses the sample cell of the laser particle size analyzer for testing.

[0082] Furthermore, after the test sample is collected, the peristaltic pump 41 and the first valve 44 are simultaneously shut off, the second valve 46 is opened, compressed air is introduced, and the peristaltic pump 41 is reversed to recover the residual slurry in the pipe into the reaction vessel 1. If necessary, the third valve 48 can be opened to connect to an external water source, allowing pure water to clean the sample remaining in the pipe.

[0083] Furthermore, after completing one test, the motor 223 can be driven to work, causing the first spiral blade 222 to rotate in the opposite direction, so that the sample in the temporary storage chamber is recovered to the bottom of the reaction vessel 1, effectively reducing the waste of materials caused by sample sampling and testing.

[0084] This device, through the aforementioned structure, can solve the technical problem in the prior art where manual sampling and testing results are subject to a certain lag, thus affecting production efficiency.

[0085] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
