Description

Technical Field

[0001] The invention relates to the technical field of lithium fluoride preparation and transportation, and in particular to a lithium fluoride preparation and transportation device. Background Art

[0002] Lithium fluoride is an inorganic salt obtained through chemical synthesis. Its preparation process includes reacting refined lithium carbonate with high-purity electronic-grade hydrofluoric acid to generate lithium fluoride. The generated lithium fluoride product is separated and dried to finally obtain high-purity lithium fluoride suitable for high-end applications such as battery manufacturing. In the preparation process, the delivery of hydrofluoric acid solution is a key link, and a specially designed delivery device is usually required to handle the hydrofluoric acid in a sealed container.

[0003] Since the existing lithium fluoride preparation and transportation device cannot effectively seal the hydrofluoric acid container in transit when transporting hydrofluoric acid solution, the trace amount of hydrofluoric acid liquid remaining outside the sealed container evaporates into hydrofluoric acid vapor. It is impossible to pre-treat the gas generated by the evaporation of the residual liquid on the surface of the container, and there is a lack of temporary collection capacity for these harmful gases, which may not only pose a threat to the health of operators, but also have an adverse effect on air quality.

[0004] Based on this, we propose a lithium fluoride preparation and transportation device to solve the above-mentioned problems. Summary of the invention

The forward and reverse motor is a servo motor in the prior art, which can accurately control the displacement adjustment distance between the material moving assembly and the material transfer box.

When the circular cover plate is docked and inserted into the interior of the circular sealing groove, a closed cavity can be formed. The closed cavity can prevent external pollutants from entering the interior, while ensuring that harmful gases inside will not leak into the external environment.

[0015] Preferably, in the above-mentioned lithium fluoride preparation and transportation device, a suction and pressure piston is connected to one end of the first suction and pressure member and the second suction and pressure member, a three-way pipe is installed on the top of the first suction and pressure member, and the two ends of the three-way pipe are respectively connected to a third one-way valve, and an air supply pipe is arranged on the top of the three-way pipe, an air bag body is installed at one end of the air supply pipe, and a fourth one-way valve is also installed at the exhaust port of the air supply pipe.

[0018] Based on the above technical features, this solution uses a support rod and a second forward and reverse screw rod installed between two sets of fourth pulleys to adjust the displacement of the space adjustment plate.

[0020] Based on the above technical features, the present scheme is to install a ratchet between the blower impeller and the first toothed pulley, and the ratchet adopts the clockwise ratchet gear in the prior art. The clockwise ratchet gear can rotate freely in the clockwise direction, but is restricted from rotating in the counterclockwise direction. Therefore, the two sets of blower impellers installed on one side of the air intake box can operate normally under the drive of the clockwise rotation of the ratchet. When the blower impeller is running, the fifth one-way valve installed at one end of the second exhaust pipe can be opened under the control of the electric control induction, so that the external air can be drawn into the interior of the airtight cavity, and the air pressure inside the airtight cavity can be restored by passing air, so that the air pressure returns to a normal state, so that the staff can open the sealing door of the sealed box body normally, and through the blowing pipe installed on one side of the air intake box, the air drawn in by the blower impeller can also be blown into the cavity formed by the splicing of the circular cover plate and the circular sealing groove, and the air pressure inside the cavity can be restored to a normal state, so that the circular cover plate can be pulled out from the interior of the circular sealing groove.

[0022] Based on the above technical features, this solution can improve the sealing of the contact between the space adjustment plate and the airtight cavity and the sealing door by wrapping the sealing rubber ring around the edges of the space adjustment plate.

[0023] Preferably, in the above-mentioned lithium fluoride preparation and transportation device, a second air extraction pipe is installed on one side of the inner part of the shielding cover, the second air extraction pipe is connected to the first air extraction pipe, and a fifth one-way valve is also installed at one end of the second air extraction pipe.

By allowing air to pass, the air pressure inside the airtight cavity is restored to normal, so that the staff can open the sealing door of the sealed box normally.

[0025] Preferably, in the above-mentioned lithium fluoride preparation and conveying device, the suction and pressing piston includes a telescopic rod, one end of the telescopic rod is installed with a piston plate, and the end of the telescopic rod away from the piston plate is also provided with a positioning card plate, the positioning card plate matches the card plate groove structure, and the positioning card plate and the card plate groove are snap-fitted.

[0026] Based on the above technical features, this solution can clamp and limit one end of the suction and pressure piston to one end of the displacement adjustment substrate through the structural design of the clamping fit between the positioning clamp and the clamp groove, and the displacement adjustment substrate can also disassemble, connect, repair and replace the suction and pressure piston according to the usage.

[0027] The present invention provides a lithium fluoride preparation and transportation device, which has the following technical points and beneficial effects:

[0028] The lithium fluoride preparation and conveying device designed in the present invention is mainly composed of a displacement adjustment substrate, a material moving component and a material transfer box. The transmission component in the material moving component plays a key role. The transmission component is composed of multiple pulleys and a transmission belt. When the material moving component and the material transfer box move relatively on the top of the displacement adjustment substrate, the transmission gear will drive these pulleys to rotate counterclockwise synchronously. The fourth pulley is connected to the second forward and reverse screw through a threaded matching structure, thereby realizing the compression adjustment of the internal space adjustment plate of the airtight cavity. By compressing the space adjustment plate, the internal space of the airtight cavity is reduced, making it easier to form a negative pressure environment. In this process, the first suction and pressure member and the second suction and pressure member are used in combination. The first suction and pressure member extracts the air in the airtight cavity through the suction and pressure piston and the connected air supply pipe, further reducing the air pressure to ensure that the volatile gas in the hydrofluoric acid solution storage tank will not leak. At the same time, the second suction and pressure member maintains a negative pressure state, and uniformly discharges harmful gases through a one-way valve system connected to the gas discharge pipe.

[0029] When the device needs to take out the hydrofluoric acid solution storage tank inside the airtight cavity, the device will restore the normal air pressure inside the airtight cavity through a series of transmission mechanisms. First, the blower impeller located on one side of the air inlet box starts to operate. With the help of the transmission connection between the clockwise ratchet and the second toothed pulley of the device, the external air is quickly drawn into the airtight cavity. This process not only restores the normal air pressure state inside the airtight cavity, but also enables the sealing door of the sealed box to be opened smoothly, thereby ensuring that the operator can safely take out the storage tank. In order to avoid the leakage of harmful gases during the process of restoring normal air pressure, the device ensures the unified emission management of volatile gases through the precise coordination of gas exhaust pipe fittings and multiple one-way valves. The airbag body located in the first extraction and pressure member, after storing some harmful gases, safely discharges these harmful gases through the gas exhaust pipe fittings. This emission process is controlled by multiple one-way valves such as the fourth one-way valve and the second one-way valve, avoiding direct contact between harmful gases and operators, thereby improving the safety of operation.

[0030] The operation of the lithium fluoride preparation and transportation device designed in the present invention relies on the drive of the forward and reverse motors, which not only realizes the closed transit transportation of hydrofluoric acid liquid, but also effectively isolates the volatile gas through the negative pressure principle. Through this series of closely coordinated designs, the equipment not only improves the safe handling ability of hydrofluoric acid during transportation, but also improves the functionality and practicality of the overall operation. The device provides more reliable technical support for the preparation and transportation of lithium fluoride. At the same time, the design of this scheme also takes into account various safety hazards. Through effective air pressure control and emission management of harmful gases, it can not only achieve effective pressure extraction and isolation in the airtight cavity, but also reduce the contact between hydrofluoric acid vapor and the external environment, thereby improving the safety and effectiveness of the device in the process of lithium fluoride preparation and transportation, and greatly reducing the potential threat to the health of operators.

[0059] See also Figures 1 to 6 The present invention provides a technical solution for a lithium fluoride preparation and transportation device:

A transmission belt 235 is also connected between the fourth pulley 234 and the second pulley 232 and the first pulley 231 and the second pulley 232.

[0062] The sealing box 21 and the bottom of the material transfer box 3 are both connected with a first guide plate 211, and a first positive and negative screw hole 212 is opened through the middle of the first guide plate 211. The sealing box 21 is installed with a second guide plate 213 on both sides close to the first guide plate 211. One side of the two sets of second guide plates 213 is rotatably connected with a transmission gear 214, and the transmission gear 214 is connected to the third pulley 233. A round cover plate 215 is arranged on the top of the side of the sealing box 21 away from the sealing box 21, and a first connector 216 is installed inside the round cover plate 215. A second connector 217 is provided at the bottom of the first connector 216. By installing a circular cover plate 215 on the top of one side of the sealed box body 21, the circular cover plate 215 can realize the rapid connection and separation of the sealed box body 21 and other components through the design of the first connector 216 and the second connector 217, thereby ensuring the stability and sealing of the connection during operation. At the same time, the setting of the circular cover plate 215 can also provide additional protection during the operation of the equipment, preventing external pollutants from entering the interior, and ensuring that harmful gases inside will not leak into the external environment.

[0063] A suction and pressure piston 221 is connected to one end of the first suction and pressure member 22 and the second suction and pressure member 38, a three-way pipe 222 is installed on the top of the first suction and pressure member 22, and the two ends of the three-way pipe 222 are respectively connected to the third one-way valve 223, and an air supply pipe 224 is arranged on the top of the three-way pipe 222, and an air bag body 225 is installed at one end of the air supply pipe 224, and a fourth one-way valve 226 is also installed at the exhaust port of the air supply pipe 224.

When the material moving component 2 and the material transfer box 3 are moved and adjusted on the top of the displacement adjustment substrate 1, the meshing connection design between the transmission tooth plate 16 and the transmission gear 214 can drive the sealed box body 21 and the transmission gear 214 installed at the bottom of the material transfer box 3 to rotate. Since the transmission gear 214 at the bottom of the material transfer box 3 and the third pulley 233 are in transmission connection, the displacement-adjusted sealed box body 21 can drive the transmission component 23 to rotate.

[0069] Two sets of blower impellers 281 are installed on one side of the air intake box 28, and a ratchet 282 is connected to one side of the two sets of blower impellers 281. A first toothed belt pulley 283 is set on one side of the two sets of ratchet wheels 282. A second toothed belt pulley 284 is installed on one side of the air intake box 28, and the second toothed belt pulley 284 is transmission-connected to the first belt pulley 231.

An air blowing pipe 286 is connected to one side of the air intake box 28, and a first air exhaust pipe 287 is also set on the side of the air intake box 28 away from the air blowing pipe 286.

[0070] During operation, a ratchet 282 is installed between the blower impeller 281 and the first toothed pulley 283. The ratchet 282 adopts a clockwise ratchet gear in the prior art. The clockwise ratchet gear can rotate freely in the clockwise direction, but is restricted from rotating in the counterclockwise direction. Therefore, the two sets of blower impellers 281 installed on one side of the air intake box 28 can operate normally under the drive of the clockwise rotation of the ratchet 282. When the blower impeller 281 is running, the fifth one-way valve 242 installed at one end of the second exhaust pipe 241 can be opened under the control of the electric control induction, which can The external air is drawn into the interior of the airtight cavity 25, and the air pressure inside the airtight cavity 25 is restored by passing air, so that the air pressure returns to normal, so that the staff can open the sealing door of the sealing box body 21 normally. Through the blowing pipe 286 installed on one side of the air inlet box 28, the air drawn in by the blower impeller 281 can also be blown into the cavity formed by the joint between the circular cover plate 215 and the circular sealing groove 31, and the air pressure inside the cavity is restored to normal, so that the circular cover plate 215 can be pulled out from the interior of the circular sealing groove 31.

[0071] As an embodiment of the present invention, Figures 8 to 10 As shown, the edges of the space adjustment plate 27 are wrapped with a sealing rubber ring 271, and a second forward and reverse screw hole 272 is opened through the top of the space adjustment plate 27. The second forward and reverse screw hole 272 and the second forward and reverse screw rod 2342 are threadedly matched. A limiting frame 273 is also provided in the middle of one side of the space adjustment plate 27. The sealing rubber ring 271 wrapped around the edges of the space adjustment plate 27 can improve the sealing of the contact between the space adjustment plate 27 and the airtight cavity 25 and the sealing door. A second exhaust pipe 241 is installed on one side of the interior of the shielding cover 24. The second exhaust pipe 241 is connected to the first exhaust pipe 287, and a fifth one-way valve 242 is also installed at one end of the second exhaust pipe 241.

[0072] The suction and pressure piston 221 includes a telescopic rod 2211, one end of which is installed with a piston plate 2212, and the end of the telescopic rod 2211 away from the piston plate 2212 is also provided with a positioning card plate 2213, the positioning card plate 2213 matches the card plate groove 14 structure, and the positioning card plate 2213 and the card plate groove 14 are snap-fitted. Through the structural design of the snap-fitting between the positioning card plate 2213 and the card plate groove 14, one end of the suction and pressure piston 221 can be snap-fitted and limited to one end of the displacement adjustment substrate 1, and the displacement adjustment substrate 1 can also perform disassembly, assembly, connection, maintenance and replacement operations on the suction and pressure piston 221 according to the usage.

[0073] During operation, when the blower impeller 281 is running, the fifth one-way valve 242 installed at one end of the second exhaust pipe 241 can be opened under the control of the electric control induction, and the external air can be drawn into the interior of the airtight cavity 25. The air pressure inside the airtight cavity 25 is restored by the introduction of air, so that the air pressure returns to normal, so that the staff can open the sealed door of the sealed box 21 normally.

[0074] Working principle: The lithium fluoride preparation and conveying device designed in the present invention is mainly composed of a displacement adjustment substrate 1, a material moving component 2 and a material transfer box 3, wherein the displacement adjustment substrate 1 comprises a first guide groove 11, a first forward and reverse screw 12, a forward and reverse motor 13, a card slot 14, a second guide groove 15, a transmission gear plate 16 and a third guide groove 17. The displacement adjustment substrate 1 is designed by thread matching between the first forward and reverse screw 12 and the first forward and reverse screw hole 212. When the forward and reverse motor 13 is powered on and rotated forward and reverse, the material moving component 2 and the material transfer box 3 installed on the top of the displacement adjustment substrate 1 can be relatively or reversely moved according to the usage. The forward and reverse motor 13 is a servo motor in the prior art, which can accurately control the displacement adjustment distance between the material moving component 2 and the material transfer box 3. When the material moving component 2 and the material transfer box 3 are moved and adjusted on the top of the displacement adjustment substrate 1, the meshing connection design between the transmission tooth plate 16 and the transmission gear 214 can drive the sealed box body 21 and the transmission gear 214 installed at the bottom of the material transfer box 3 to rotate. Since the transmission gear 214 at the bottom of the material transfer box 3 is connected to the third pulley 233 through transmission, the displacement-adjusted sealed box body 21 can drive the transmission component 23 to rotate;

[0075] The transmission component 23 in this scheme is composed of a first pulley 231, a second pulley 232, a third pulley 233, a fourth pulley 234 and a transmission belt 235. When the material moving component 2 and the material transfer box 3 are moved and adjusted in relative directions on the top of the displacement adjustment substrate 1, the transmission gear 214 can drive all the pulleys to rotate counterclockwise synchronously. The fourth pulley 234 can perform spatial compression adjustment on the space adjustment plate 27 installed on one side of the two groups of airtight cavities 25 through the thread matching structure design between the second forward and reverse screw hole 272 and the second forward and reverse screw rod 2342. The edges of the space adjustment plate 27 are wrapped with a sealing rubber ring 271 to improve the sealing between the space adjustment plate 27 and the airtight cavity 25 and the sealing door. By adjusting the space adjustment plate 27, a certain space inside the airtight cavity 25 can be compressed, and at the same time, the hydrofluoric acid solution storage tank placed in the airtight cavity 25 can be limited.

[0076] In this solution, a first pressure-drawing member 22 is installed on one side of the bottom of the sealed box body 21, and a second pressure-drawing member 38 is connected to the bottom of one side of the material transfer box 3. When the material moving component 2 and the material transfer box 3 are moved and adjusted in relative directions on the top of the displacement adjustment substrate 1, the pressure-drawing pistons 221 in the transition fit in the first pressure-drawing member 22 and the second pressure-drawing member 38 can be pulled outward, and the first pressure-drawing member 22 is connected to the inside of the airtight cavity 25 through the three-way pipe 222 and the third one-way valve 223. The air pressure in the airtight cavity 25 can be extracted and transferred to the inside of the first pressure-drawing member 22, so as to realize a negative pressure environment inside the airtight cavity 25. When the hydrofluoric acid solution storage tank is stored in the airtight cavity 25, the hydrofluoric acid vapor generated by volatilization can be prevented from overflowing from the inside of the airtight cavity 25, thereby effectively reducing the probability of contact between the hydrofluoric acid vapor and the staff. The inside of the pressure piece 38 is still in a negative pressure state and has not been released. The first one-way valve 36 is installed at one end of the gas discharge pipe 35, and the second pressure-extracting piece 38 is connected to the first one-way valve 36. The one-way valves in this scheme all adopt the electrically controlled one-way valves in the prior art. When the round-shaped cover plate 215 is docked and inserted into the inside of the round-shaped sealing groove 31, the electrically controlled one-way valve controls the opening and closing of the valve through the electromagnetic coil and the control circuit. At this time, the second pressure-extracting piece 38 in the negative pressure state can perform a pressure-extracting process on the inside of the cavity formed by the splicing between the round-shaped cover plate 215 and the round-shaped sealing groove 31, so that the inside is in a negative pressure state, thereby improving the sealing performance of the docking connection between the second connector 217 and the third connector 32 and the first connector 216 and the fourth connector 34, and can also effectively prevent the hydrofluoric acid vapor generated by volatilization from overflowing from the inside of the cavity formed by the splicing between the round-shaped cover plate 215 and the round-shaped sealing groove 31;

[0077] When the material moving component 2 and the material transfer box 3 are moved and adjusted in opposite directions on the top of the displacement adjustment substrate 1, the transmission gear 214 can drive the first pulley 231, the second pulley 232, the third pulley 233, and the fourth pulley 234 to rotate synchronously clockwise. The fourth pulley 234 can reset the space adjustment plate 27 for compressing and adjusting the inner space of the two groups of airtight cavities 25 through the threaded matching design between the second forward and reverse screw hole 272 and the second forward and reverse screw rod 2342. The original space inside the airtight cavity 25 is restored by resetting the space adjustment plate 27, so as to facilitate the removal of the hydrofluoric acid solution storage tank from the airtight cavity 25. Through the second toothed belt pulley 284 installed on one side of the air inlet box 28, and the second toothed belt pulley 284 and the first pulley 231 are connected by transmission, when the first pulley 231 rotates synchronously clockwise under the drive of the transmission gear 214, the second toothed belt pulley 284 can be driven to rotate synchronously clockwise. The ratchet wheel 282 is installed between the wheels 283. The ratchet wheel 282 adopts the clockwise ratchet gear in the prior art and can rotate freely in the clockwise direction, but is restricted from rotating in the counterclockwise direction. Therefore, the two sets of blower impellers 281 installed on one side of the air intake box 28 can operate normally under the drive of the clockwise rotation of the ratchet wheel 282. When the blower impeller 281 is running, the fifth one-way valve 242 installed at one end of the second exhaust pipe 241 can be opened under the control of the electric control induction to draw the external air into the airtight The air pressure inside the airtight cavity 25 is restored by introducing air, so that the air pressure inside the airtight cavity 25 is restored to a normal state, so that the staff can normally open the sealing door of the sealing box body 21. Through the air blowing pipe 286 installed on one side of the air inlet box 28, the air sucked in by the blower impeller 281 can also be blown into the cavity formed by the splicing between the circular cover plate 215 and the circular sealing groove 31, so that the internal air pressure is restored to a normal state, so that the circular cover plate 215 can be pulled out from the circular sealing groove 31.

[0078] When the material moving component 2 and the material transfer box 3 are moved and adjusted in opposite directions on the top of the displacement adjustment substrate 1, the transition-matched pumping and pressing pistons 221 in the first pumping and pressing member 22 and the second pumping and pressing member 38 can be pushed inward, and the first pumping and pressing member 22 can transport the harmful gas in the first pumping and pressing member 22 to the interior of the airbag body 225 through the three-way pipe 222, the air supply pipe 224 and the fourth one-way valve 226 installed on the top. When the first connector 216 and the fourth connector 34 are docked and connected again, the harmful gas temporarily stored in the airbag body 225 can be discharged outward through the gas exhaust pipe 35, and the harmful gas in the second pumping and pressing member 38 can be discharged into the gas exhaust pipe through the second one-way valve 37 installed between the gas exhaust pipe 35 and the first one-way valve 36. The interior of the component 35 can achieve unified treatment of harmful gas emissions and avoid direct contact between harmful gases and workers. In summary, the lithium fluoride preparation and transportation device designed by the present invention can achieve closed transit transportation of hydrofluoric acid liquid storage containers through the operation of a group of forward and reverse motors 13. The forward and reverse motors 13 can also drive the transmission component 23 to run synchronously while moving in the forward or reverse direction. Through the transmission structure of the transmission component 23, the device can also adjust the piston pressure of the first pumping and pressing component 22 and the second pumping and pressing component 38, and use the cavity negative pressure principle to achieve effective isolation of hydrofluoric acid vapor generated by volatilization, reduce the contact probability between hydrofluoric acid vapor and operators, thereby improving the functionality and practicality of the device in the field of lithium fluoride preparation and transportation technology.
