Description

Technical Field

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

[0002] Lithium hexafluorophosphate is an inorganic compound, which is a white crystalline powder, soluble in water, and soluble in organic solvents such as low-concentration methanol, ethanol, acetone, and carbonate esters. It is mainly used as an electrolyte material for lithium-ion batteries. During the production process of lithium hexafluorophosphate, it is necessary to monitor and sample its reaction process and purification process.

[0003] Currently, the existing sampling methods include manual sampling and intelligent sampling. Among them, the equipment cost of intelligent sampling and the requirements for control programs are relatively high, which is not suitable for the configuration of small workshops. Manual sampling places a heavy burden on workers, and since lithium hexafluorophosphate is easily decomposed when in contact with air during the sampling process, the sampling operation is rather troublesome. For example: A Chinese patent with the authorization announcement number CN216847033U discloses a lithium hexafluorophosphate detection and sampling device, which includes a packaging barrel and a sampling tube connected to the bottom thereof. A sampling bottle is arranged below the sampling tube. A stirring shaft is rotatably arranged vertically in the packaging barrel, and stirring plates are arranged circumferentially at the bottom of the stirring shaft. A transfer box is hermetically sleeved on the lower part of the sampling tube, and sampling bottles can be detachably arranged on both sides of the bottom of the transfer box. A sealing plug is hermetically slidably connected in the sampling tube.

[0004] Although the technical solution in the above patent document simplifies the sampling steps, it can only sample the materials in a single reaction tank. When facing the sampling operations of multiple reaction tanks in a workshop, it is impossible to quickly sample multiple reaction tanks simultaneously, making it difficult to ensure that each sample truly reflects the real situation of the materials in the corresponding reaction tank under the same period conditions. Moreover, the sampling operations of multiple reaction tanks place a heavy burden on workers, and frequent sampling operations are extremely likely to result in sampling failures, causing losses of samples and injuries to personnel. Summary of the Invention

A sample temporary storage component 5 for temporarily storing samples is provided below the sampling mechanism 3. A conveying mechanism for transporting the sample temporary storage component 5 is jointly provided below the plurality of sampling mechanisms 3. An inflation mechanism 7 for gas filling and a liquid pumping mechanism 8 for liquid suction are also installed on the conveying component 4. The arrangement of the conveying mechanism can perform synchronous displacement adjustment on the plurality of sample temporary storage components 5, and thus, in cooperation with the corresponding sampling mechanisms 3, synchronous sampling of materials in the plurality of reaction tanks 1 can be achieved.

[0044] Please refer to Figures 14 - 15, in the embodiment of the present invention, the sample bottle 54 includes a bottle body 541 placed in a placement frame 53. A seal 542 is installed at the mouth of the bottle body 541. The seal 542 includes a capping box 5421 threadedly connected to the mouth of the bottle body 541. A rectangular groove is formed at the top of the capping box 5421. Thus, when the sample bottle 54 is displaced below the sampling mechanism 3, the edge of the top of the capping box 5421 contacts the sampling mechanism 3, realizing the sealing contact between the sample bottle 54 and the sampling mechanism 3. An accommodation chamber is formed inside the capping box 5421. Cavities are formed on the inner walls on both sides of the accommodation chamber, and round rods 5423 are arranged in the cavities. A material passing hole is formed at the center of the capping box 5421, and the material passing hole and the port of the bottle body 541 are on the same axis line. Sealing baffles 5422 for blocking are symmetrically arranged on the left and right in the accommodation chamber, and the mutual approach of the two sealing baffles 5422 realizes the blocking of the material passing hole. Sliders movably connected to the corresponding round rods 5423 are installed on the front and rear sides of each sealing baffle 5422. A return spring sleeved on the corresponding round rod 5423 is arranged on the side wall of each slider. The arrangement of the return spring enables the sealing baffle 5422 to reset without external force, thereby realizing the blocking of the material passing hole and ensuring the stable reset of the traction member 326 in the vertical component 32.

[0045] On the mutually remote sides of the two sealing baffles 5422, they respectively penetrate through the corresponding side walls of the accommodation chamber, and U-shaped grooves for the assembly of the lifting member 3262 are formed.

[0046] Please refer to Figures 1 - 5 , in the embodiment of the present invention, a placement plate is integrally arranged on the side wall of the bottom plate 411. The motor 61 is arranged on the top shell wall of the placement plate through a cushion seat. The left end of the transmission shaft is installed with an L-shaped plate through a bearing. The bottom of the L-shaped plate is fixedly connected to the top of the placement plate through bolts. The driven gear 63 is arranged at the left end of the front side movable roller.

[0047] A convex rod is installed on the right shell wall of the disc 65, and a vertical groove is formed on the moving plate 66. The convex rod is movably connected in the vertical groove, and the bottom of the moving plate 66 is slidably connected to the bottom plate 411.

[0048] Please refer to Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 11 , in the embodiment of the present invention, the inflation mechanism 7 includes an inflation pump main body 71 arranged on the bottom plate 411. An inflation main pipe 72 is arranged at the air outlet port of the inflation pump main body 71. The air inlet port of the inflation pump main body 71 is connected to an external air source through a pipeline, and the air source adopts an inert gas, such as nitrogen, etc. A plurality of branch pipes are linearly distributed on the inflation main pipe 72, and a plurality of intake pipes 36 and the corresponding branch pipes are connected through hoses.

[0049] The liquid extraction mechanism 8 includes a liquid extraction pump main body 81 disposed on the bottom plate 411, and a liquid extraction main pipe 82 is provided on the feed port of the liquid extraction pump main body 81. The discharge port of the liquid extraction pump main body 81 is connected to an external collection tank through a pipeline, and is used for cleaning the residual materials after sampling. One ends of a plurality of liquid extraction pipes 35 far away from the corresponding vertical components 32 are all disposed on the liquid extraction main pipe 82.

[0050] The working principle of the present invention is as follows: when the materials are being processed in the reaction tank 1, the stirring motor 21 in the stirring mechanism 2 moves under the control of an external controller main body, drives the corresponding stirring shaft 22 to move, and realizes stirring of the materials in the corresponding reaction tank 1.

[0051] When sampling operations need to be performed on a plurality of reaction tanks 1, the external controller main body first turns on the air inflation pump main body 71 in the air inflation mechanism 7 and the liquid extraction pump main body 81 in the liquid extraction mechanism 8. Then, the control valves on each liquid extraction pipe 35 are started, so that each liquid extraction pipe 35 is communicated with the vertical pipe one 321 in the corresponding vertical component 32. At this time, the liquid extraction main pipe 82 in the liquid extraction mechanism 8 extracts the liquid and gas in the vertical component 32 under the action of the operation of the liquid extraction pump main body 81, so that a negative pressure state is formed inside the vertical component 32. The time for the external controller main body to turn on the control valve can be preset, and the control valve will close automatically after being turned on for a period of time.

[0052] Next, the external controller main body controls the motor 61 in the driving mechanism 6 to run counterclockwise, and the motor 61 drives the half gear 62 to rotate. The first half of the movement of the half gear 62 is in meshing transmission with the driven gear 63, and then drives the conveying member 42 in the conveying assembly 4 to move. Since the motor 61 takes half a turn of movement as one mileage, the motor 61 will pause for a period of time after rotating half a turn, and then start running the remaining half turn again. During one mileage of the movement of the half gear 62, its meshing transmission with the driven gear 63 realizes the movement of the conveying member 42 for one mileage. Furthermore, the conveying member 42 drives a plurality of sample temporary storage components 5 located on the conveying assembly 4 to synchronously displace for one mileage, realizing the displacement switching of a plurality of sample bottles 54 linearly placed in the sample temporary storage components 5.

[0053] After each sample temporary storage component 5 completes the displacement switching, the new unused sample bottle 54 moves to directly below the corresponding sampling mechanism 3 and plugs the bottom end of the vertical pipe two 322 in the sampling mechanism 3. And when the sample bottle 54 moves below the sampling mechanism 3, the U-shaped grooves on each sealing plate 5422 of the seal 542 in the sample bottle 54 are respectively slidably inserted into the lifting members 3262 of the traction members 326 of the vertical component 32 in the sampling mechanism 3.

[0054] Finally, the external controller body starts the motor 61 in the driving mechanism 6 again. At this time, the half gear 62 disengages from the driven gear 63 and thus will not drive the conveying member 42 to move. However, the half gear 62 meshes with the transmission gear 64 at this time, and drives the disc 65 to rotate through the transmission shaft. During the rotation of the disc 65, it drives the moving plate 66 to linearly slide, and synchronously drives the active wedge block 68 to displace and adjust through the fixed rod 67. During the movement of the active wedge block 68, it contacts the driven wedge block 434 of the pusher 43 in the conveying assembly 4 and applies an extrusion force to it. After the driven wedge block 434 is stressed, it drives the corresponding slide plate 431 to displace through the bent rod 433, and thus the contact rod 432 moves. During the displacement of the contact rod 432, it contacts the movable member 315 of the shunt member 31 in each sampling mechanism 3 and pushes against it. After the movable member 315 is stressed, it moves in the movement direction of the contact rod 432, stretching the adjusting rod 313 and the push-pull member 334 in the adjusting assembly 33. After the adjusting rod 313 is pulled, it compresses the return spring and drives the plug 314 to displace.

[0055] When the push-pull member 334 moves with the movement of the movable member 315, due to the constraint of the guiding member 335, the vertical plate 333 drives the pipe body 331 to move downward during the movement of the movable member 315.

[0056] When the air inlet pipe 36 on the pipe body 331 leaves the vertical pipe one 321 in the vertical component 32, under the action of the operation of the air inflation pump body 71 in the air inflation mechanism 7, the main air inflation pipe 72 and each corresponding hose input the inert gas from the air inlet pipe 36 into each corresponding vertical component 32. The filling of the inert gas into the vertical component 32 enables the air remaining in the vertical component 32 to be discharged through the gas one-way valve 34, realizing the filling of the inert gas in the vertical component 32.

[0057] During the continuous downward movement of the pipe body 331, when the air inlet pipe 36 on the pipe body 331 contacts the vertical pipe two 322, the air inlet pipe 36 is blocked. At this time, the plug 314 still realizes the blocking of the slot hole. During the continuous downward movement of the pipe body 331, the plug 314 cancels the blocking of the slot hole, and thus the material in the reaction tank 1 directly enters the vertical component 32 from the reaction tank 1 through the shunt pipe 311 in the shunt member 31 under the action of gravity.

[0058] At this time, the fixed ring 332 in the adjusting assembly 33 contacts the moving ring 324 and performs a pressing operation on it. After the moving ring 324 is stressed and moves downward, it drives the corresponding pressing rod 325 to move synchronously. During the downward movement of the pressing rod 325, it adjusts the traction belt in the corresponding traction member 326, enabling the traction belt to move on the corresponding steering wheel 3261 and pulling the corresponding lifting member 3262 to displace.

[0059] Thereby, the baffle plate 5422 of the seal 542 in the corresponding sample bottle 54 is opened, so that the material in the vertical component 32 directly flows into the corresponding bottle body 541, thus realizing the sampling operation of the material.

[0060] Under the action of gravity, the material flows following the displacement of the sealing plug 314. When the sealing plug 314 cancels the blockage of the slot hole, the material then enters the vertical component 32. Furthermore, when the baffle plate 5422 of the seal 542 in the sample bottle 54 is opened, the material also enters the bottle body 541, and there is no need to pause the equipment waiting for the material to fall.

[0061] 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 complete the synchronous sampling of the material in the corresponding reaction tank 1.

[0062] After the half gear 62 completes the movement of the remaining half circle, the half gear 62 disengages from the transmission gear 64. As a result, the active wedge 68 lacks the force applied to the driven wedge 434. The return springs of the shunt member 31 in each sampling mechanism 3, the compression spring on the pressing rod 325 in the vertical component 32, and the return spring in the seal 542 of the corresponding sample bottle 54 perform return movements, respectively causing the shunt member 31, the traction member 326 in the vertical component 32, and the baffle plate 5422 in the seal 542 to return.

[0063] When the shunt member 31 returns, the pusher 43 automatically returns. Then, the driven wedge 434 squeezes and adjusts the active wedge 68, causing the fixed rod 67 and the moving plate 66 to perform a return movement, thereby driving the reverse movement of the disc 65.

[0064] Since the number of teeth of the transmission gear 64 is more than that of the driven gear 63, the half gear 62 rotating half a circle can drive the driven gear 63 to rotate synchronously half a circle, but the transmission gear 64 cannot rotate a half - circle path, which provides favorable conditions for the active wedge 68 to drive the return of the moving plate 66.

[0065] The return of the shunt member 31 realizes the blockage of the material inside the reaction tank 1, and the return of the baffle plate 5422 realizes the reset blockage of the seal 542 in the sample bottle 54, avoiding the sample in the sample bottle 54 from contacting the air.

[0066] After sampling is completed, the external controller main body opens the control valves on each liquid extraction pipe 35 again, realizing the re - extraction of the liquid and gas in the vertical component 32 of each sampling mechanism 3, avoiding the material in the vertical component 32 from being discharged and contacting the air when the sample temporary storage component 5 is switched.

[0067] In a cycle, the synchronous sampling of the materials in multiple reaction tanks 1 is thus realized.

[0068] When randomly selecting any one of the reaction vessels 1 for spot-checking the materials in a single reaction vessel 1, after selecting a reaction vessel 1, the sample temporary storage assembly 5 used in this reaction vessel 1 is integrally moved a certain distance on the cross plate 413, so that the new sample bottle 54 of the sample temporary storage assembly 5 moves to directly below the sampling mechanism 3.

[0069] When the sample temporary storage assembly 5 is manually pushed on the cross plate 413, since the push top plate on the conveyor belt in the conveyor 42 and the base are arranged through the cooperation of a pin shaft and a torsion spring, when the sample temporary storage assembly 5 moves forward actively, the push top plate will not hinder the sample temporary storage assembly 5, which is convenient for the displacement adjustment of the sample temporary storage assembly 5. After the position adjustment of the sample temporary storage assembly 5 is completed, the inflation mechanism 7 and the liquid pumping mechanism 8 are started through an external controller main body to realize the negative pressure adjustment of the vertical component 32 in the sampling mechanism 3. Then, the movable part 315 of the shunt part 31 in the sampling mechanism 3 is manually pulled, so as to realize the sampling operation of the sampling mechanism 3 on the materials in the corresponding reaction vessel 1.

[0070] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
