Description

Technical Field

[0001] This invention belongs to the field of detection equipment technology, specifically relating to a spectrometer and detection method for detecting monazite components. Background Technology

[0002] Monazite is an important raw material for extracting rare earth elements. Rare earth elements are a group of chemically similar metallic elements, including the lanthanides, scandium, and yttrium. These elements are widely used in various high-tech products, such as smartphones, computer hard drives, hybrid vehicle batteries, wind turbine magnets, fiber optic communication equipment, and medical devices. Monazite compositional analysis helps assess the economic value of monazite deposits and provides a scientific basis for mining investment.

[0003] Monazite does indeed possess radioactivity because it contains thorium (Th) and uranium (U), both of which are radioactive. Traditional methods of ore analysis using spectrometers leave ore samples exposed and lacking protection against radioactivity, severely damaging the environment around the testing room and impacting the health of the testing personnel. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a spectrometer for the detection of monazite components. The present invention can place the monazite sample into the sample box inside the protective box, and then place the protective box into the instrument box for detection. The opening and closing of the protective box is completed inside the instrument box during the entire detection process, and it is only opened for a short time during the detection, which prevents the monazite sample from being directly exposed to the air, effectively prevents the radioactivity of monazite from affecting the surrounding environment of the detection room, and effectively protects the health of the detection personnel.

[0005] The technical solution adopted to solve the above technical problems is: a spectrometer for monazite composition detection, including a chassis, a conveyor belt, a detection mechanism, a feed door and a discharge door. The conveyor belt is fixedly connected to the bottom of the chassis. A receiving chamber is provided on the rear side of the chassis. The detection mechanism is slidably connected in the receiving chamber. The feed door is vertically slidably connected to the top of one side of the chassis. The discharge door is rotatably connected to the other side of the chassis.

[0006] The conveyor belt can transport the protective box, and a sample box is fixedly connected inside the protective box;

[0007] The horizontal sliding of the detection mechanism can drive the protective box to open or close.

[0008] Using the above technical solution, the prepared monazite sample is placed in the sample box inside the protective chamber. During testing, the protective chamber is placed into the machine through the inlet and falls onto the conveyor belt. Then, the inlet gate is pressed down and closed, and the machine is in a sealed state. The conveyor belt sends the protective chamber to the front of the receiving chamber, and the testing mechanism slides horizontally out of the receiving chamber. During the horizontal sliding of the testing mechanism, the protective chamber is opened. When the testing mechanism slides directly above the sample box, the monazite sample in the sample box can be tested. After the test is completed, the testing mechanism slides horizontally back into the receiving chamber. During this process, the testing mechanism drives the protective chamber to close. Then, the conveyor belt transports the protective chamber to the discharge gate side. The discharge gate is opened, and the tested protective chamber can be taken out. The opening and closing of the protective chamber is completed inside the machine during the entire testing process, and it is only opened for a short time during testing, effectively preventing the radioactivity of monazite from affecting the surrounding environment of the testing room and effectively ensuring the health of the testing personnel.

[0009] Furthermore, the protective box includes a lid, a rotating bracket, a base plate, a connecting rod, and a driving component. The lid is slidably connected to the top of the protective box, the rotating bracket is fixedly connected to the lid, two base plates are symmetrically fixedly connected to the inner wall of the protective box, the driving component is rotatably connected to the base plate, one end of the connecting rod is hinged to the rotating bracket, and the other end of the connecting rod is hinged to the driving component.

[0010] With the above technical solution, since one end of the connecting rod is hinged to the rotating bracket and the other end of the connecting rod is hinged to the driving component, the driving component drives the connecting rod, the connecting rod can drive the rotating bracket, and the driving bracket can drive the box cover to open or close.

[0011] Furthermore, the rotating bracket includes a support plate and a crossbar. The support plates are symmetrically fixedly connected to the bottom of the box cover in two sets. The crossbar is fixedly connected between the two support plates. A first cylinder and a second cylinder are fixedly connected to the outside of the support plate.

[0012] With the above technical solution, since the crossbar is fixedly connected between the two support plates, the two support plates can move simultaneously, ensuring the stability of the box lid opening and closing.

[0013] Furthermore, the substrate is provided with vertical grooves and arc-shaped grooves inside, and the vertical grooves and arc-shaped grooves are connected, so that the first cylinder and the second cylinder can slide in the vertical grooves or arc-shaped grooves.

[0014] With the above technical solution, since the substrate has vertical grooves and arc grooves inside, and the vertical grooves and arc grooves are connected, the first cylinder and the second cylinder can slide in either the vertical groove or the arc groove. When the lid is closed, both the first cylinder and the second cylinder are in the vertical groove. During the opening of the lid, the first cylinder and the second cylinder rise simultaneously in the vertical groove. At this time, the lid rises, and then the first cylinder stops sliding at the top of the vertical groove, while the second cylinder enters the arc groove and continues to slide. At this time, the support plate rotates around the first cylinder, which drives the lid to rotate. After the second cylinder reaches the top of the arc groove, it stops sliding, and the lid is fully opened.

[0015] During the closing process, the second cylinder descends along the arc groove and eventually enters the vertical groove. As the second cylinder descends along the arc groove, the support plate flips in the opposite direction with the first cylinder as the center. When the second cylinder enters the vertical groove, the lid flips to a horizontal position and is directly above the protective box. Then, the first and second cylinders descend simultaneously in the vertical groove, that is, the lid descends vertically. Finally, the lid is attracted to the top of the protective box, and the lid is closed.

[0016] Furthermore, the driving component includes a driven gear and a transmission rod. The transmission rod is fixedly connected to the driven gear shaft, which passes through the base plate and the protective box wall. The transmission rod is disposed inside the protective box, and the driven gear is disposed outside the protective box. One end of the connecting rod is hinged to the transmission rod, and the other end of the connecting rod is hinged to the crossbar.

[0017] With the above technical solution, since the transmission rod is fixedly connected to the driven gear shaft, the driven gear shaft passes through the base plate and the protective box wall, the transmission rod is set inside the protective box, the driven gear is set outside the protective box, one end of the connecting rod is hinged to the transmission rod, and the other end of the connecting rod is hinged to the crossbar, so that the rotation of the driven gear can drive the transmission rod, the transmission rod can drive the connecting rod to move, and the connecting rod can drive the crossbar to move. The crossbar is coaxial with the second cylinder, and the movement of the crossbar can drive the box cover to open or close.

[0018] When the driven gear rotates forward, the transmission rod drives the connecting rod to rise, and the connecting rod drives the crossbar to rise, thus opening the cover. When the driven gear rotates in reverse, the transmission rod drives the connecting rod to fall, and the connecting rod drives the crossbar to fall, thus closing the cover.

[0019] Furthermore, the detection mechanism includes a detection frame, a detection probe, and an electric telescopic rod. A hydraulic push rod is installed inside the receiving chamber, and the other end of the hydraulic push rod is fixedly connected to the detection frame. The detection probe is vertically slidably connected inside the detection frame. The electric telescopic rod is fixedly connected to the top of the detection frame, and the bottom of the electric telescopic rod is fixedly connected to the top of the detection probe. A drive rack is fixedly connected to one side of the detection frame, and the drive rack meshes with a driven gear.

[0020] With the above technical solution, a hydraulic push rod is installed inside the containment chamber. The other end of the hydraulic push rod is fixedly connected to the detection frame. The detection probe is vertically slidably connected inside the detection frame. An electric telescopic rod is fixedly connected to the top of the detection frame. The bottom of the electric telescopic rod is fixedly connected to the top of the detection probe. A drive rack is fixedly connected to one side of the detection frame. The drive rack meshes with the driven gear, so that the hydraulic push rod can push the detection frame to slide horizontally above the protective box. When the detection frame reaches the top of the protective box, the electric telescopic rod can drive the detection probe to descend and detect the monazite sample in the sample box inside the protective box. After the detection is completed, the electric telescopic rod can drive the detection probe to rise, and the hydraulic push rod brings the detection frame back into the containment chamber without hindering the transport of the protective box.

[0021] During the process of the hydraulic push rod pushing out the detection frame, the drive rack slides out horizontally along with the detection frame. At this time, the drive rack drives the driven gear to rotate forward, and the forward rotation of the driven gear can drive the box cover to open. After the detection is completed, during the process of the hydraulic push rod bringing the detection frame back, the drive rack slides back horizontally along with the detection frame. At this time, the drive rack drives the driven gear to rotate in reverse, and the reverse rotation of the driven gear can drive the box cover to close.

[0022] Furthermore, the sample box includes a top cover, a bottom box, a sample holder, and a support plate. The top cover is threaded onto the bottom box. A spring is fixedly connected to the bottom of the support plate, and the bottom of the spring is fixedly connected to the bottom box. The sample holder is placed on top of the support plate, and the top cover is snapped onto the sample holder. The top of the top cover has a hollowed-out design in the middle.

[0023] With the above technical solution, the top cover is threaded onto the bottom box, and a spring is fixedly connected to the bottom of the support plate. The bottom of the spring is fixedly connected to the bottom box. The sample holder is placed on the top of the support plate, and the top cover is snapped onto the sample holder. The top of the top cover has a hollow design in the middle, so that the sample can be placed on the sample holder. After the sample holder is placed on the support plate, the top cover is put down, and the top cover is screwed onto the bottom box. The sample is then installed, and the sample can be directly tested through the hollow design on the top cover.

[0024] Furthermore, a first handle is fixedly connected to the top of the feed gate, a limit plate is fixedly connected to the bottom of the feed gate, a helical rack is fixedly connected to one side of the limit plate, a helical gear is fixedly connected to the conveyor belt shaft, the helical rack meshes with the helical gear in one direction, positioning posts are also evenly distributed on the conveyor belt, a positioning groove is correspondingly provided at the bottom of the protective box, the positioning groove can be locked on the positioning post, a guide groove is provided on one side of the protective box, and a guide plate is provided on one side of the feed inlet inside the machine box, the guide groove and the guide plate are slidably connected.

[0025] With the above technical solution, since a limit plate is fixedly connected to the bottom of the feed gate, a helical rack is fixedly connected to one side of the limit plate, and a helical gear is fixedly connected to the conveyor belt shaft, the helical rack and the helical gear mesh in one direction, so that when the feed gate is lowered and closed, the helical rack can drive the helical gear to rotate, thereby driving the conveyor belt to run a certain distance, just enough to allow the protective box entering below the feed gate to reach the detection mechanism. When the feed gate is raised and opened, the helical rack does not drive the helical gear to rotate.

[0026] Because there are also positioning posts evenly distributed on the conveyor belt, and a corresponding positioning groove is set at the bottom of the protective box, the positioning groove can be locked on the positioning post. A guide groove is set on one side of the protective box, and a guide plate is set on the side of the feed inlet inside the machine. The guide groove and the guide plate are slidably connected, so that when the protective box enters the machine, it is assisted by the guide groove and the guide plate. When the protective box falls onto the conveyor belt, the positioning groove can be locked on the positioning post, which makes it convenient for the detection mechanism to open and close the protective box.

[0027] Magnets can also be installed on the limit plate, which is attached to the top of the machine box, allowing the feed door to be temporarily suspended for easy placement of protective boxes. The first handle facilitates the opening and closing of the feed door.

[0028] Furthermore, a second handle is fixedly connected to the top of the discharge gate.

[0029] The above technical solution facilitates the opening and closing of the discharge door by providing a second handle.

[0030] A spectrometer-based method for analyzing the composition of monazite, the method is as follows:

[0031] Step 1: The sample preparation personnel put on full protective clothing and complete the crushing, grinding and tableting process of the marked monazite samples in the radiation protection room. The tableted samples are then placed into sample boxes in different protective boxes according to the markings. The protective boxes are then closed and sent to the testing room.

[0032] Step 2: Start the testing agency and use it to test the standard substances with known components, thereby calibrating the testing agency to ensure that it is in optimal working condition, and collect calibration data to generate calibration curves;

[0033] Step 3: Open the feed gate and place the protective box into the machine. The protective box falls onto the conveyor belt. Close the feed gate. At the same time as the feed gate closes, drive the conveyor belt to transport the protective box to the testing mechanism. Then the testing mechanism works. The testing mechanism slides horizontally out of the receiving chamber. During the horizontal sliding of the testing mechanism, it drives the protective box to open. When the testing mechanism slides directly above the sample box, it can test the monazite sample in the sample box. After the test is completed, the testing mechanism slides horizontally back into the receiving chamber. During this process, the testing mechanism drives the protective box to close. Then the conveyor belt transports the protective box to the discharge gate. The discharge gate opens, and the tested protective box can be taken out. Collect the tested protective boxes and store them properly.

[0034] Step 4: Use the data processing software provided by the testing institution to process the recorded signals, calculate the content of each element in the sample, correct the data according to the calibration curve, correct any other possible interference factors, and compile the analysis results into a report, including sample information, testing methods, analysis results and conclusions. Compare the analysis results with known data or expected results to verify the accuracy and reliability of the data.

[0035] The beneficial effects of this invention are as follows:

[0036] (1) In this invention, the protective box is driven to open during the horizontal sliding process of the detection mechanism. When the detection mechanism slides to the top of the sample box, the monazite sample in the sample box can be detected. After the detection is completed, the detection mechanism slides back into the container. During this process, the detection mechanism drives the protective box to close. In the entire detection process, the protective box is only opened and closed briefly during the detection, and all of the detection is carried out in a sealed box, which maximizes the prevention of radiation pollution of the surrounding environment and effectively protects the health of the detection personnel.

[0037] (2) In the process of closing the box cover in this invention, the second cylinder first descends along the arc groove, and finally the second cylinder enters the vertical groove. When the second cylinder descends along the arc groove, the support plate flips in the opposite direction with the first cylinder as the center. When the second cylinder enters the vertical groove, the box cover flips to the horizontal and is directly above the protective box. Then the first cylinder and the second cylinder descend simultaneously in the vertical groove, that is, the box cover descends vertically. Finally, the box cover is attracted to the top of the protective box, and the box cover is closed. The closed protective box will not be accidentally opened due to vibration or other special reasons during transportation. It effectively protects the sample and prevents radiation pollution of the environment, effectively ensuring the health of the transport personnel. Attached Figure Description

[0057] 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.

[0058] like Figure 1 - Figure 3 As shown, a spectrometer for detecting monazite composition includes a housing 1, a conveyor belt 2, a detection mechanism 4, a feed door 6, and a discharge door 7. The conveyor belt 2 is fixedly connected to the bottom of the housing 1. A receiving chamber 11 is provided on the rear side of the housing 1. The detection mechanism 4 is slidably connected to the receiving chamber 11. The feed door 6 is vertically slidably connected to the top of one side of the housing 1. The discharge door 7 is rotatably connected to the other side of the housing 1.

[0059] Conveyor belt 2 can transport protective box 3, and sample box 5 is fixedly connected inside the protective box 3;

[0060] The horizontal sliding of the testing mechanism 4 can drive the protective box 3 to open or close.

[0061] In this embodiment, the prepared monazite sample is placed into the sample box 5 inside the protective box 3. During testing, the protective box 3 is placed into the machine housing 1 through the feed inlet. The protective box 3 falls onto the conveyor belt 2, and then the feed gate 6 is pressed down, closing the feed gate 6. At this time, the machine housing 1 is in a sealed state. The conveyor belt 2 sends the protective box 3 to the front of the receiving chamber 11. The detection mechanism 4 slides horizontally out from the receiving chamber 11. During the horizontal sliding process, the detection mechanism 4 drives the protective box 3 to open. When the detection mechanism 4 slides directly above the sample box 5, the monazite sample in the sample box 5 can be tested. After the test is completed, the detection mechanism 4 slides horizontally back into the receiving chamber 11. During this process, the detection mechanism 4 drives the protective box 3 to close. Then, the conveyor belt 2 transports the protective box 3 to the side of the discharge gate 7. The discharge gate 7 is opened, and the tested protective box 3 can be taken out. The opening and closing of the protective box 3 is completed within the machine housing 1 throughout the entire testing process, and it is only opened for a short time during testing, effectively preventing the radioactivity of monazite from affecting the surrounding environment of the testing room and effectively ensuring the health of the testing personnel.

[0062] like Figure 4 - Figure 13 As shown, the protective box 3 includes a box cover 31, a rotating bracket 32, a base plate 33, a connecting rod 34, and a driving component 35. The box cover 31 is slidably connected to the top of the protective box 3, the rotating bracket 32 ​​is fixedly connected to the box cover 31, the base plate 33 consists of two symmetrical base plates fixedly connected to the inner wall of the protective box 3, the driving component 35 is rotatably connected to the base plate 33, one end of the connecting rod 34 is hinged to the rotating bracket 32, and the other end of the connecting rod 34 is hinged to the driving component 35.

[0063] The rotating bracket 32 ​​includes a support plate 321 and a crossbar 322. The support plate 321 is symmetrically fixedly connected to the bottom of the box cover 31 in two sets. The crossbar 322 is fixedly connected between the two support plates 321. A first cylinder 3211 and a second cylinder 3212 are fixedly connected to the outside of the support plate 321.

[0064] The substrate 33 has a vertical groove and an arc groove inside, and the vertical groove and the arc groove are connected. The first cylinder 3211 and the second cylinder 3212 can slide in the vertical groove or the arc groove.

[0065] The driving component 35 includes a driven gear 351 and a transmission rod 352. The transmission rod 352 is fixedly connected to the shaft of the driven gear 351. The shaft of the driven gear 351 passes through the base plate 33 and the wall of the protective box 3. The transmission rod 352 is located inside the protective box 3, and the driven gear 351 is located outside the protective box 3. One end of the connecting rod 34 is hinged to the transmission rod 352, and the other end of the connecting rod 34 is hinged to the crossbar 322.

[0066] The detection mechanism 4 includes a detection frame 41, a detection probe 42, and an electric telescopic rod 43. A hydraulic push rod is installed inside the receiving chamber 11, and the other end of the hydraulic push rod is fixedly connected to the detection frame 41. The detection probe 42 is vertically slidably connected inside the detection frame 41. The electric telescopic rod 43 is fixedly connected to the top of the detection frame 41, and the bottom of the electric telescopic rod 43 is fixedly connected to the top of the detection probe 42. A drive rack 44 is fixedly connected to one side of the detection frame 41, and the drive rack 44 meshes with the driven gear 351.

[0067] In this embodiment, the hydraulic push rod can push the detection frame 41 to slide horizontally above the protective box 3. When the detection frame 41 reaches the top of the protective box 3, the electric telescopic rod 43 can drive the detection probe 42 to descend and detect the monazite sample in the sample box 5 inside the protective box 3. After the detection is completed, the electric telescopic rod 43 can drive the detection probe 42 to rise, and the hydraulic push rod will bring the detection frame 41 back into the receiving chamber 11 without hindering the transport of the protective box 3.

[0068] During the process of the hydraulic push rod pushing out the detection frame 41, the drive rack 44 slides out horizontally along with the detection frame 41. At this time, the drive rack 44 drives the driven gear 351 to rotate forward, the transmission rod 352 drives the connecting rod 34 to rise, the connecting rod 34 drives the crossbar 322 to rise, the first cylinder 3211 and the second cylinder 3212 rise simultaneously in the vertical groove. At this time, the box cover 31 rises, and then the first cylinder 3211 reaches the top of the vertical groove and stops sliding, while the second cylinder 3212 enters the arc groove and continues to slide. At this time, the support plate 321 rotates around the first cylinder 3211 as the center, that is, it drives the box cover 31 to rotate. After the second cylinder 3212 reaches the top of the arc groove, it stops sliding, and the box cover 31 is fully opened.

[0069] After the test is completed, as the hydraulic push rod brings the test frame 41 back, the drive rack 44 slides horizontally back along with the test frame 41. At this time, the drive rack 44 drives the driven gear 351 to reverse, the transmission rod 352 drives the connecting rod 34 to descend, the connecting rod 34 drives the crossbar 322 to descend, the second cylinder 3212 descends along the arc groove first, and finally the second cylinder 3212 enters the vertical groove. When the second cylinder 3212 descends along the arc groove, the support plate 321 flips in the opposite direction with the first cylinder 3211 as the center. When the second cylinder 3212 enters the vertical groove, the cover 31 flips to be horizontal and is directly above the protective box 3. Then the first cylinder 3211 and the second cylinder 3212 descend simultaneously in the vertical groove, that is, the cover 31 descends vertically. Finally, the cover 31 is attracted to the top of the protective box 3, and the cover 31 is closed.

[0070] like Figure 15 - Figure 16As shown, the sample box 5 includes a top cover 51, a bottom box 52, a sample holder 53, and a support plate 54. The top cover 51 is threaded onto the bottom box 52. A spring 541 is fixedly connected to the bottom of the support plate 54. The bottom of the spring 541 is fixedly connected to the bottom box 52. The sample holder 53 is placed on top of the support plate 54. The top cover 51 is snapped onto the sample holder 53. The top center of the top cover 51 is hollowed out.

[0071] In this embodiment, the sample can be placed on the sample holder 53, the sample holder 53 is placed on the support plate 54, and then the top cover 51 is put down. After the top cover 51 and the bottom box 52 are screwed together, the sample is installed and the sample can be directly tested through the cutout on the top cover 51.

[0072] like Figure 14 as well as Figure 17 - Figure 18 As shown, a first handle 63 is fixedly connected to the top of the feed gate 6, a limit plate 62 is fixedly connected to the bottom of the feed gate 6, a helical rack 61 is fixedly connected to one side of the limit plate 62, a helical gear 21 is fixedly connected to the shaft of the conveyor belt 2, the helical rack 61 and the helical gear 21 mesh in one direction, positioning posts 22 are also evenly distributed on the conveyor belt 2, a positioning groove 37 is correspondingly provided at the bottom of the protective box 3, the positioning groove 37 can be locked on the positioning post 22, a guide groove 36 is provided on one side of the protective box 3, a guide plate 12 is provided on one side of the feed inlet inside the machine box 1, the guide groove 36 is slidably connected to the guide plate 12, and a second handle 71 is fixedly connected to the top of the discharge gate 7.

[0073] In this embodiment, when the feed gate 6 is lowered and closed, the helical rack 61 can drive the helical gear 21 to rotate, thereby driving the conveyor belt 2 to run a certain distance, just enough for the protective box 3 entering from below the feed gate 6 to reach the detection mechanism 4. When the feed gate 6 is raised and opened, the helical rack 61 does not drive the helical gear 21 to rotate.

[0074] When the protective box 3 enters the machine housing 1, it is assisted by the guide groove 36 and the guide plate 12. When the protective box 3 falls onto the conveyor belt 2, the positioning groove 37 can be locked onto the positioning post 22, which makes it convenient for the detection mechanism 4 to open and close the protective box 3.

[0075] A magnet can also be installed on the limiting plate 62, which is attached to the top of the machine box 1, so that the feeding door 6 can be temporarily suspended, making it convenient to put the protective box 3. The first handle 63 is set to facilitate the opening and closing of the feeding door 6, and the second handle 71 is set to facilitate the opening and closing of the discharging door 7.

[0076] A spectrometer-based method for analyzing the composition of monazite, the method is as follows:

[0077] Step 1: The sample preparation personnel put on full protective clothing and complete the crushing, grinding and tableting process of the marked monazite samples in the radiation protection room. The tableted samples are placed into sample boxes 5 in different protective boxes 3 according to the markings. The protective boxes 3 are closed and sent into the testing room.

[0078] Step 2: Start the testing mechanism 4 and use it to test the standard substances with known components, thereby calibrating the testing mechanism 4, ensuring that the testing mechanism 4 is in optimal working condition, and collecting calibration data to generate a calibration curve.

[0079] Step 3: Open the feed gate 6 and put the protective box 3 into the machine box 1. The protective box 3 falls onto the conveyor belt 2. Close the feed gate 6. At the same time as the feed gate 6 closes, the conveyor belt 2 can be driven to transport the protective box 3 to the testing mechanism 4. Then the testing mechanism 4 works. The testing mechanism 4 slides horizontally out of the receiving chamber 11. During the horizontal sliding of the testing mechanism 4, the protective box 3 is driven to open. When the testing mechanism 4 slides directly above the sample box 5, the monazite sample in the sample box 5 can be tested. After the test is completed, the testing mechanism 4 slides horizontally back into the receiving chamber 11. During this process, the testing mechanism 4 drives the protective box 3 to close. Then the conveyor belt 2 transports the protective box 3 to the side of the discharge gate 7. The discharge gate 7 is opened, and the tested protective box 3 can be taken out. Collect the tested protective boxes 3 and store them properly.

[0080] Step 4: Use the data processing software provided by the testing institution to process the recorded signals, calculate the content of each element in the sample, correct the data according to the calibration curve, correct any other possible interference factors, and compile the analysis results into a report, including sample information, testing methods, analysis results and conclusions. Compare the analysis results with known data or expected results to verify the accuracy and reliability of the data.

[0081] Working principle:

[0082] During operation, the tableted samples are placed into sample boxes 5 inside different protective boxes 3 according to the markings, the protective boxes 3 are closed, and the protective boxes 3 are sent into the testing chamber.

[0083] When the feed gate 6 is opened, the protective box 3 is put into the machine box 1. When the protective box 3 enters the machine box 1, it is assisted by the guide groove 36 and the guide plate 12. When the protective box 3 falls onto the conveyor belt 2, the positioning groove 37 can be just locked on the positioning column 22.

[0084] When the feed gate 6 is closed and descended to close, the helical rack 61 can drive the helical gear 21 to rotate, thereby driving the conveyor belt 2 to run a certain distance, just enough to allow the protective box 3 that enters below the feed gate 6 to reach the front of the receiving bin 11;

[0085] The hydraulic push rod is activated, which pushes out the detection frame 41. During the process of pushing out the detection frame 41, the drive rack 44 slides out horizontally along with the detection frame 41. At this time, the drive rack 44 drives the driven gear 351 to rotate forward, the transmission rod 352 drives the connecting rod 34 to rise, and the connecting rod 34 drives the crossbar 322 to rise. The first cylinder 3211 and the second cylinder 3212 rise simultaneously in the vertical groove. At this time, the box cover 31 rises. Then, the first cylinder 3211 stops sliding when it reaches the top of the vertical groove, while the second cylinder 3212 enters the arc groove and continues to slide. At this time, the support plate 321 rotates around the first cylinder 3211, which drives the box cover 31 to rotate. The second cylinder 3212 stops sliding after reaching the top of the arc groove, and the box cover 31 is fully opened.

[0086] Then, when the detection frame 41 reaches above the protective box 3, the electric telescopic rod 43 can drive the detection probe 42 to descend and detect the monazite sample in the sample box 5 inside the protective box 3.

[0087] After the test is completed, the electric telescopic rod 43 can drive the test probe 42 to rise, and the hydraulic push rod will bring the test frame 41 back into the receiving chamber 11.

[0088] During the process of the hydraulic push rod bringing the detection frame 41 back, the drive rack 44 slides horizontally back along with the detection frame 41. At this time, the drive rack 44 drives the driven gear 351 to reverse, the transmission rod 352 drives the connecting rod 34 to descend, the connecting rod 34 drives the crossbar 322 to descend, the second cylinder 3212 descends along the arc groove first, and finally the second cylinder 3212 enters the vertical groove. When the second cylinder 3212 descends along the arc groove, the support plate 321 flips in the opposite direction with the first cylinder 3211 as the center. When the second cylinder 3212 enters the vertical groove, the box cover 31 flips to the horizontal and is directly above the protective box 3. Then the first cylinder 3211 and the second cylinder 3212 descend simultaneously in the vertical groove, that is, the box cover 31 descends vertically. Finally, the box cover 31 is attracted to the top of the protective box 3, and the box cover 31 is closed.

[0089] Open the feed door 6 again, put the protective box 3 to be tested into the machine box 1, close the feed door 6, and before the protective box 3 to be tested reaches the receiving bin 11, the protective box 3 that has been tested reaches the vicinity of the discharge door 7. Open the discharge door 7, take out the protective box 3 that has been tested and recycle it.

[0090] Throughout the entire testing process, the protective boxes were only briefly opened and closed during testing, and all testing was conducted within the sealed enclosure 1, minimizing radiation contamination of the surrounding environment and effectively protecting the health of the testing personnel.

[0091] After all tests are completed, the protective box 3 is properly stored, data is collected, analyzed, and a report is generated.

[0092] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
