Description

Technical Field

[0001] The invention relates to the technical field of lithium hexafluorophosphate sampling, in particular to a monitoring sampling device for lithium hexafluorophosphate. Background Art

[0002] Lithium hexafluorophosphate (LFP) is an inorganic compound, a white crystalline powder, readily soluble in water and low-concentration organic solvents such as methanol, ethanol, acetone, and carbonates. It is primarily used as an electrolyte material in lithium-ion batteries. During the production of LFP, the reaction and purification processes require monitoring and sampling.

[0003] At present, the existing sampling methods include manual sampling and intelligent sampling. Among them, the equipment cost and control program requirements of intelligent sampling are relatively high, which is not suitable for the configuration of small workshops. Manual sampling puts a heavy burden on labor, and because lithium hexafluorophosphate is easily decomposed by contact with air during the sampling process, the sampling operation is relatively troublesome. For example: A Chinese patent with authorization announcement number CN216847033U discloses a lithium hexafluorophosphate detection sampling device, including a packaging barrel and a sampling tube connected to the bottom thereof, a sampling bottle is provided below the sampling tube, a stirring shaft is provided in the packaging barrel for vertical rotation, a stirring plate is provided in the annular direction at the bottom of the stirring shaft, a sealing sleeve at the bottom of the sampling tube is provided with a transfer box, and sampling bottles are detachably provided on both sides of the bottom of the transfer box, and a sealing plug is provided in the sampling tube for sealing and sliding connection.

[0004] Although the technical solution in the above patent document simplifies the sampling steps, it can only perform sampling operations on the materials in a single reaction tank. When faced with sampling operations on multiple reaction tanks in a workshop, it is impossible to quickly achieve rapid sampling of multiple reaction tanks at the same time. It is difficult to ensure that each sample truly reflects the actual situation of the materials in the corresponding reaction tank under the same state at the same time. In addition, the sampling operation of multiple reaction tanks places a heavy burden on manual labor, and frequent sampling operations are very likely to result in sampling failures, resulting in sample loss and personal injury.

Then, under the action of the driving mechanism, the corresponding sample temporary storage components can be progressively conveyed by the conveying mechanism, thereby realizing automatic switching of sample bottles and opening and operating the sampling mechanism, thereby performing synchronous and automated material sampling on multiple reaction tanks, reducing the manual burden, improving work efficiency, and ensuring personnel safety.

[0050] See also Figure 1-Figure 2 In an embodiment of the present invention, a monitoring and sampling device for lithium hexafluorophosphate includes a plurality of linearly distributed reaction components, including a reaction tank 1 and a stirring mechanism 2. The stirring mechanism 2 disposed on the reaction tank 1 can improve the efficiency of material processing within the reaction tank 1 and prevent crystallization and precipitation of the material within the reaction tank 1.

[0051] Each reaction tank 1 is equipped with a sampling mechanism 3 for material sampling. Below the sampling mechanism 3 is a sample storage assembly 5 for temporarily storing samples. A conveyor mechanism for transporting the sample storage assemblies 5 is located beneath the multiple sampling mechanisms 3. The conveyor assembly 4 is also equipped with an inflation mechanism 7 for gas filling and a liquid extraction mechanism 8 for liquid aspiration. This conveyor mechanism allows for synchronous displacement adjustment of the multiple sample storage assemblies 5, thereby enabling simultaneous sampling of materials from multiple reaction tanks 1 in conjunction with the corresponding sampling mechanisms 3.

[0052] See also Figure 3-Figure 4In this embodiment of the present invention, the conveying mechanism includes a conveying assembly 4 and a driving mechanism 6. The conveying assembly 4 includes a frame 41 that serves as a supporting structure. Mounted on the frame 41 are a conveying member 42 for conveying the sample storage assembly 5 and a push member 43 for adjusting the sampling mechanism 3. The conveying member 42 is configured to convey the sample storage assembly 5 placed on the frame 41.

[0053] See also Figure 4-Figure 6 In the embodiment of the present invention, the driving mechanism 6 includes a motor 61 provided on the conveying assembly 4, and a half gear 62 is installed at the output end of the motor 61. A driven gear 63 for driving the conveying member 42 is provided on the front side of the half gear 62, and a transmission gear 64 is installed on the rear side of the half gear 62 via a transmission shaft. The half gear 62 and the driven gear 63 are meshed and transmitted, and the half gear 62 and the transmission gear 64 are also meshed and transmitted. The number of teeth on the half gear 62 is half that of the driven gear 63, and the number of teeth on the transmission gear 64 is greater than that of the driven gear 63. Therefore, a half-turn rotation of the half gear 62 can drive the driven gear 63 to move 180 degrees, but cannot drive the transmission gear 64 to move 180 degrees.

[0054] A disc 65 is mounted on the right end of the drive shaft, with a movable plate 66 movably connected to the right side of the disc 65. A fixed rod 67 is mounted on the sidewall of the movable plate 66, and the rear end of the fixed rod 67 is fixedly connected to an active wedge 68 that drives the pusher 43. The half gear 62 drives the drive gear 64, which in turn rotates the disc 65 via the drive shaft, causing the movable plate 66 to move linearly, which in turn drives the active wedge 68 via the fixed rod 67.

[0055] See also Figure 7-10 In this embodiment of the present invention, the sampling mechanism 3 includes a diverter 31 disposed on the reaction tank 1, with a vertical assembly 32 mounted on the diverter 31. An adjustment assembly 33 is movably mounted on the vertical assembly 32, and an air inlet pipe 36 is mounted on the adjustment assembly 33. A gas check valve 34 and a liquid extraction pipe 35 are located above the adjustment assembly 33 and are located on the vertical assembly 32. The diverter 31 seals and diverts the material in the reaction tank 1, thereby enabling sampling of the material through the movement of the diverter 31 in conjunction with the vertical assembly 32 and the adjustment assembly 33.

[0056] See also Figure 7-Figure 8 In the embodiment of the present invention, the reaction tank 1 includes a tank body 11 for material reaction, with a tank cover 12 mounted on the top of the tank body 11 via bolts. The stirring mechanism 2 includes a stirring motor 21 fixedly connected to the tank cover 12 via bolts. The output end of the stirring motor 21 is mounted with a stirring shaft 22 extending into the interior of the tank body 11. The peripheral wall of the tank body 11 is provided with a hole for mounting the sampling mechanism 3. The hole is designed to be inclined on the tank body 11, so that the sampling mechanism 3 is also tilted when installed.

[0057] See also Figure 9 In the embodiment of the present invention, the diverter 31 includes a diverter tube 311 disposed in the hole, and the top of the diverter tube 311 is threadedly connected to an end cap 312. The threaded connection between the end cap 312 and the diverter tube 311 allows the diverter 31 to be disassembled and cleaned.

[0058] End cap 312 has a circular hole at its center, into which an adjustment rod 313 is movably connected. The bottom end of adjustment rod 313 is located inside shunt tube 311 and is fitted with a sealing plug 314 for sealing. Sealing plug 314 is provided to prevent leakage of material from reactor 1 and to facilitate sampling and adjustment.

[0059] The top of the adjustment rod 313 is located outside the shunt tube 311 and is bolted to a movable member 315. This member 315 consists of an end plate and a support rod. The end plate is bolted to the top of the adjustment rod 313, while the support rod is fixed to the bottom of the end plate. A return spring, located on the adjustment rod 313, is sleeved between the sealing plug 314 and the end cap 312. This spring ensures that the adjustment rod 313 can be reset and adjusted without external force.

[0060] See also Figures 9-13 In an embodiment of the present invention, the vertical component 32 includes a slotted hole formed on the diverter tube 311, and the vertical component 32 includes a vertical tube 1 321 disposed in the slotted hole. A vertical tube 2 322 is disposed directly below the vertical tube 1 321. The diameters of the vertical tubes 1 321 and 2 322 are the same, which facilitates the loading and sampling of materials. When the sealing plug 314 cancels the blockage of the slotted hole during movement, the blocking effect is not completely canceled, and due to the inclined design of the end face of the sealing plug 314, the material does not contact the gas check valve 34 during the sampling process.

[0061] The first vertical tube 321 and the second vertical tube 322 are connected by a curved plate assembly. This curved plate assembly consists of three curved plates, circumferentially arranged between the first and second vertical tubes 321 and 322, to connect them. The gaps between the curved plates facilitate the passage of inert gas.

[0062] A base ring 323 is integrally mounted on the outer ring of the bottom end of the second vertical tube 322. A movable ring 324 is sleeved above the base ring 323 and positioned on the second vertical tube 322. Two pressing rods 325 are mounted on the bottom of the movable ring 324.

[0063] Each pressing rod 325 is provided with a through hole on the base ring 323 below, and the bottom ends of the pressing rods 325 respectively pass through the corresponding through holes and are installed with traction members 326. The moving ring 324 drives the pressing rods 325 to move, thereby causing the traction members 326 to move.

[0064] Each pressing rod 325 is equipped with a compression spring, the top of which is mounted on the bottom wall of the movable ring 324, and the bottom of which is mounted on the top wall of the base ring 323. The compression spring is provided to facilitate the reset adjustment of the movable ring 324 and to ensure that the movable ring 324 is kept at a high position without external force.

[0065] The traction member 326 includes a steering wheel 3261 and a lifting member 3262. The steering wheel 3261 is mounted on the bottom wall of the base ring 323 via a straight plate assembly. The lifting member 3262 is slidably connected to the bottom wall of the base ring 323. A traction belt is wrapped around the steering wheel 3261, one end of which is attached to the lifting member 3262, and the other end is attached to a corresponding pressing rod 325. The lifting member 3262 includes an integration plate slidably connected to the bottom wall of the base ring 323. A plurality of insertion rods are linearly arranged at the bottom of the integration plate.

[0066] The top of the adjustment assembly 33 is provided with a connection hole and a mounting hole for the first vertical tube 321. A gas check valve 34 is installed in the mounting hole, and a liquid extraction pipe 35 is also installed in the connection hole. The liquid extraction pipe 35 is also equipped with a control valve. The liquid extraction pipe 35 adopts a curved pipe structure. The bottom end of the pipe in the vertical assembly 32 is aligned with the bottom end of the second vertical tube 322, which facilitates the extraction of materials remaining in the vertical assembly 32.

[0067] Adjustment assembly 33 comprises a tubular body 331 sleeved over vertical tube 1 321. A fixed ring 332 is integrally mounted on the outer ring of the bottom end of tubular body 331, which is used to press against movable ring 324. Above fixed ring 332 is a vertical plate 333, located on the outer wall of tubular body 331. Vertical plate 333 defines an inclined slot, into which a push-pull member 334 slides. Push-pull member 334 comprises a rod movably connected to the inclined slot. Strip plates are mounted on both the front and rear ends of the rod, and a restraining ring is mounted on the right ends of both strip plates.

[0068] The push-pull member 334 is slidably connected to a guide member 335, the bottom of which is fixedly connected to the conveying assembly 4. The guide member 335 includes a slide slidably connected to two strip plates, the bottom of which is fixedly connected to a support rod, the bottom of which is fixedly connected to the conveying assembly 4.

[0069] The push-pull member 334 is also slidably connected to the movable member 315. The restraining ring in the push-pull member 334 is movably sleeved on the support rod of the movable member 315.

[0070] The peripheral wall of the tube body 331 is provided with a notch, in which the air inlet pipe 36 is installed. The top and bottom inner rings of the tube body 331 are both provided with sealing rings for improving sealing performance.

[0071] See also Figure 3-Figure 6 and Figure 16 In this embodiment of the present invention, the frame 41 includes a bottom plate 411, with side plates 412 welded to the front and rear sides of the bottom plate 411. A horizontal plate 413 is provided above the bottom plate 411 and located between the two side plates 412. The horizontal plate 413 is used to support the sample storage assembly 5 and has a rectangular through slot.

[0072] The conveying member 42 is located between the bottom plate 411 and the cross plate 413. The conveying member 42 includes two movable rollers and a conveyor belt. The two movable rollers are respectively arranged on the inner wall of the corresponding side plate 412 through a carrier. The two movable rollers are connected by a conveyor belt, and a plurality of bases are equidistantly arranged on the outer surface of the conveyor belt. A push plate is movably connected to each base through a pin shaft, wherein the pin shaft is also provided with a torsion spring for resetting and adjusting the push plate. The arrangement of the push plate and the base through the pin shaft and the torsion spring can enable the conveying member 42 to drive the synchronous displacement of multiple sample storage components 5, and can also realize manual displacement adjustment of a single sample storage component 5 on the rack 41.

[0073] A groove is formed on each side plate 412. The pusher 43 includes a slide plate 431 slidably connected to the groove. A contact rod 432 for pushing the sampling mechanism 3 is provided between the two slide plates 431.

[0074] A curved rod 433 is mounted on the outer wall of each slide 431, and the two curved rods 433 are connected by a driven wedge 434. The driven wedge 434 is slidably connected to the top wall of the base plate 411, ensuring the stability of the driven wedge 434's movement under load. The inclined surface of the driven wedge 434 slides in contact with the inclined surface of the active wedge 68. As the active wedge 68 moves, it compresses and applies force to the driven wedge 434, causing the curved rod 433 to move each slide 431, thereby driving the contact rod 432 to adjust its displacement.

[0075] See also Figure 1 、 Figure 3 and Figure 7-12In this embodiment of the present invention, the sample storage assembly 5 includes a carrier plate 51 placed on the horizontal plate 413. A protrusion 52 is integrally provided at the bottom center of the carrier plate 51. The bottom of the protrusion 52 extends through a rectangular through-slot and contacts a corresponding ejection plate. As the conveyor 42 operates, the ejection plate pushes against the protrusion 52 to adjust the displacement of the sample storage assembly 5. A plurality of placement frames 53 are linearly distributed along the top of the carrier plate 51. Sample bottles 54 for temporarily storing samples are placed in these placement frames 53.

[0076] See also Figure 14-15 In an embodiment of the present invention, the sample bottle 54 includes a bottle body 541 placed in a placement frame 53. A sealing member 542 is installed at the mouth of the bottle body 541, and the sealing member 542 includes a cover box 5421 that is threadedly connected to the mouth of the bottle body 541. A rectangular groove is provided on the top of the cover box 5421, and when the sample bottle 54 is moved to the bottom of the sampling mechanism 3, the edge of the top of the cover box 5421 contacts the sampling mechanism 3, thereby achieving a sealed contact between the sample bottle 54 and the sampling mechanism 3. A storage chamber is provided inside the cover box 5421, and cavities are provided on the inner walls of both sides of the storage chamber, and a round rod 5423 is provided in the cavity. A material passage hole is provided at the center of the cover box 5421, and the material passage hole and the port of the bottle body 541 are on the same axis. The storage chamber is symmetrically provided with sealing plates 5422 for blocking, and the two sealing plates 5422 are close to each other to achieve the blocking of the material passage hole. Each sealing plate 5422 is equipped with sliders movably connected to the corresponding round rod 5423 on its front and rear sides. Each slider is fitted with a return spring mounted on the sidewall of the corresponding round rod 5423. The return spring allows the sealing plate 5422 to return to its original position without external force, thereby sealing the material passage and ensuring the stable return of the pulling member 326 in the vertical assembly 32.

[0077] The sides of the two sealing plates 5422 that are away from each other respectively penetrate the corresponding side walls of the accommodating chamber and are provided with U-shaped grooves for assembling the lifting members 3262.

An L-shaped plate is mounted on the left end of the drive shaft via a bearing. The bottom of the L-shaped plate is bolted to the top of the support plate. A driven gear 63 is mounted on the left end of the front movable roller.

[0079] A convex rod is installed on the right side shell wall of the disc 65, and a vertical groove is provided on the movable plate 66. The convex rod is movably connected in the vertical groove, and the bottom of the movable plate 66 is slidably connected to the bottom plate 411.

[0080] See also Figure 1 、 Figure 2 、 Figure 8、 Figure 9 、 Figure 10 and Figure 11 In this embodiment of the present invention, the inflation mechanism 7 includes an inflation pump body 71 disposed on the base plate 411. An inflation main pipe 72 is provided at the outlet port of the inflation pump body 71. The inlet port of the inflation pump body 71 is connected to an external gas source via a pipe. This gas source utilizes an inert gas, such as nitrogen. Multiple branch pipes are linearly distributed on the inflation main pipe 72, and the multiple inlet pipes 36 are connected to the corresponding branch pipes via flexible hoses.

[0081] The liquid extraction mechanism 8 includes a liquid extraction pump body 81 mounted on the base plate 411. A liquid extraction main pipe 82 is mounted on the feed port of the liquid extraction pump body 81. The discharge port of the liquid extraction pump body 81 is connected to an external collection tank via a pipe for cleaning any remaining material after sampling. Multiple liquid extraction pipes 35 are each mounted on the liquid extraction main pipe 82 at their ends distal from the corresponding vertical assembly 32.

[0082] The working principle of the present invention is: when the material is processed in the reaction tank 1, the stirring motor 21 in the stirring mechanism 2 moves under the control of the external controller body, driving the corresponding stirring shaft 22 to move, thereby stirring the material in the corresponding reaction tank 1.

[0083] When sampling operations are required for multiple reaction tanks 1, the external controller body first activates the inflation pump body 71 in the inflation mechanism 7 and the liquid extraction pump body 81 in the liquid extraction mechanism 8. It then activates the control valves on each liquid extraction pipe 35, allowing each liquid extraction pipe 35 to communicate with the vertical pipe 1 321 in the corresponding vertical assembly 32. At this point, the liquid extraction main pipe 82 in the liquid extraction mechanism 8, under the action of the liquid extraction pump body 81, extracts the liquid and gas from the vertical assembly 32, creating a negative pressure state inside the vertical assembly 32. The time for the external controller body to open the control valve can be pre-set, and the control valve automatically closes after being open for a period of time.

[0084] Next, the external controller body controls the motor 61 in the drive mechanism 6 to run counterclockwise, and the motor 61 drives the half gear 62 to rotate. The first half circle of the movement of the half gear 62 is meshed with the driven gear 63, thereby driving the conveying member 42 in the conveying assembly 4 to move. Since the motor 61 moves half a circle as one mile, the motor 61 will pause for a period of time after rotating half a circle, and then start again to run the remaining half circle. During one mile of movement of the half gear 62, it is meshed with the driven gear 63 to realize the movement of the conveying member 42 for one mile. The conveying member 42 then drives the multiple sample storage assemblies 5 located on the conveying assembly 4 to synchronously shift one mile, realizing the displacement switching of the multiple sample bottles 54 linearly placed in the sample storage assembly 5.

[0085] After each sample storage assembly 5 completes its displacement switching, a new, unused sample bottle 54 moves to the position directly below the corresponding sampling mechanism 3, sealing the bottom end of the second vertical tube 322 of the sampling mechanism 3. Furthermore, as the sample bottle 54 moves below the sampling mechanism 3, the U-shaped grooves on the sealing plates 5422 of the sealing member 542 of the sample bottle 54 slide and engage with the lifting members 3262 of the pulling member 326 of the vertical assembly 32 of the sampling mechanism 3.

[0086] Finally, the external controller reactivates the motor 61 in the drive mechanism 6. The half gear 62 now disengages from the driven gear 63, thus no longer moving the conveyor 42. However, the half gear 62 engages the transmission gear 64, rotating the disc 65 via the transmission shaft. As the disc 65 rotates, it drives the linear sliding of the movable plate 66, which in turn, via the fixed rod 67, drives the active wedge 68 for adjustment. During its movement, the active wedge 68 contacts the driven wedge 434 of the pusher 43 in the conveyor assembly 4, exerting a compressive force on it. The driven wedge 434, under pressure, displaces the corresponding slide 431 via the bent rod 433, thereby moving the contact rod 432. During its movement, the contact rod 432 contacts and pushes against the movable member 315 of the diverter 31 in each sampling mechanism 3. Under pressure, the movable member 315 moves in the direction of the contact rod 432, stretching the adjustment rod 313 and the push-pull member 334 in the adjustment assembly 33. When the adjusting rod 313 is pulled, the return spring is compressed and the sealing plug 314 is driven to move.

[0087] When the push-pull member 334 moves along with the movement of the movable member 315 , due to the constraint of the guide member 335 , the vertical plate 333 drives the tube body 331 to move downward during the movement of the movable member 315 .

[0088] When the air inlet pipe 36 on the pipe body 331 leaves the vertical pipe 1 321 in the vertical assembly 32, the inflation pump main body 71 in the inflation mechanism 7 operates, and the inflation main pipe 72 and the corresponding hoses input inert gas from the air inlet pipe 36 into each corresponding vertical assembly 32. The inert gas fills the vertical assembly 32, causing the air remaining in the vertical assembly 32 to be discharged through the gas check valve 34, thus completing the filling of the vertical assembly 32 with inert gas.

[0089] As the tube body 331 continues to move downward, the air inlet pipe 36 on the tube body 331 contacts the second vertical pipe 322, blocking the air inlet pipe 36. At this point, the sealing plug 314 still seals the slot. As the tube body 331 continues to move downward, the sealing plug 314 no longer blocks the slot, allowing the material within the reactor 1 to flow directly from the reactor 1 through the diverter pipe 311 in the diverter member 31 into the vertical assembly 32 under the action of gravity.

[0090] At this point, the fixed ring 332 in the adjustment assembly 33 contacts and presses the movable ring 324. The movable ring 324 is forced downward, driving the corresponding pressing rod 325 to move synchronously. As the pressing rod 325 moves downward, it adjusts the traction belt in the corresponding traction member 326, causing the traction belt to move on the corresponding steering wheel 3261, pulling the corresponding lifting member 3262 to move.

[0091] Thus, the sealing plate 5422 of the sealing member 542 in the corresponding sample bottle 54 is opened, so that the material located in the vertical component 32 directly flows into the corresponding bottle body 541, thereby realizing the sampling operation of the material.

[0092] Under the action of gravity, the material flows closely following the displacement of the sealing plug 314. When the sealing plug 314 stops blocking the slot, the material enters the vertical assembly 32. Then, when the sealing plate 5422 of the sealing member 542 in the sample bottle 54 opens, the material also enters the bottle body 541, without pausing the equipment to wait for the material to fall.

[0093] After the motor 61 drives the half gear 62 to rotate the remaining half circle, each sampling mechanism 3 and the corresponding sample temporary storage component 5 completes the synchronous sampling of the material in the corresponding reaction tank 1.

[0094] After the half gear 62 completes the remaining half circle of movement, the half gear 62 and the transmission gear 64 are disengaged, and the active wedge 68 lacks the force to apply to the driven wedge 434. The reset spring of the diverter 31 in each sampling mechanism 3, the extrusion spring on the pressing rod 325 in the vertical component 32 and the return spring in the sealing member 542 in the corresponding sample bottle 54 perform a reset movement, respectively resetting the diverter 31, the traction member 326 in the vertical component 32 and the sealing plate 5422 in the sealing member 542.

[0095] When the diverter 31 is reset, the pusher 43 is automatically reset, and the driven wedge 434 squeezes and adjusts the active wedge 68, so that the fixed rod 67 and the movable plate 66 are reset, thereby driving the reverse movement of the disc 65.

[0096] Since the number of teeth of the transmission gear 64 is greater than that of the driven gear 63, the half gear 62 can drive the driven gear 63 to rotate half a circle synchronously when it rotates half a circle, but the transmission gear 64 cannot rotate half a circle, thereby providing favorable conditions for the active wedge block 68 to drive the movable plate 66 to reset.

[0097] The resetting of the diverter 31 seals the material inside the reaction tank 1 , while the resetting of the blocking plate 5422 seals the sealing member 542 in the sample bottle 54 , thereby preventing the sample in the sample bottle 54 from contacting the air.

[0098] After the sampling is completed, the external controller body opens the control valves on each liquid extraction tube 35 again to extract the liquid and gas in the vertical components 32 in each sampling mechanism 3 again, avoiding the discharge of materials from the vertical components 32 and contact with the air when the sample temporary storage component 5 is switched.

[0099] The process is repeated repeatedly to achieve synchronous sampling of materials in multiple reaction tanks 1 .

[0100] When sampling the material in a single reaction tank 1 , after selecting any reaction tank 1 , the sample temporary storage assembly 5 used for the reaction tank 1 is moved as a whole on the horizontal plate 413 by one mile, so that the new sample bottle 54 of the sample temporary storage assembly 5 is moved to the right below the sampling mechanism 3 .

[0101] When the sample storage assembly 5 is manually moved on the horizontal plate 413, the push-up plate on the conveyor belt of the conveyor member 42 cooperates with the base via a pin and a torsion spring. Therefore, when the sample storage assembly 5 is actively moved forward, the push-up plate does not obstruct the sample storage assembly 5, facilitating the displacement adjustment of the sample storage assembly 5. After the position of the sample storage assembly 5 is adjusted, the external controller body activates the inflation mechanism 7 and the liquid extraction mechanism 8 to achieve negative pressure adjustment of the vertical assembly 32 of the sampling mechanism 3. The movable member 315 of the diverter 31 of the sampling mechanism 3 is then manually pulled, thereby enabling the sampling mechanism 3 to sample the material in the corresponding reaction tank 1.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
