Description

Technical Field

[0001] This invention relates to the field of sodium-ion battery manufacturing technology, and in particular to a sodium-ion battery manufacturing apparatus and method based on chamber sealing and gas circulation. Background Technology

[0002] Sodium-ion batteries are secondary batteries that use Na⁺ as the charge carrier. Their structure and working principle are similar to those of lithium-ion batteries. The core difference is that sodium is used instead of lithium as the migration ion. Sodium-ion batteries are suitable for cost-sensitive, wide-temperature-range, high-safety, and large-scale energy storage scenarios, complementing lithium batteries rather than completely replacing them.

[0003] Existing sodium-ion batteries have significant drawbacks in practical use, mainly as follows: On the one hand, during the manufacturing process of sodium-ion batteries, layered metal oxides and other materials are used as positive electrode materials, which are mostly very sensitive to moisture. Residual water can trigger side reactions within the battery: residual water generated by physical or chemical adsorption can cause a series of chemical reactions within the battery, accelerating the consumption of electrolyte and corroding active materials, resulting in a decline in cycle performance. On the other hand, while the battery raw materials are being dried, in order to ensure drying efficiency, the battery raw materials need to be quantitatively input while maintaining the humidity inside the drying chamber. Multiple settings are required for the inlet and outlet doors to ensure the humidity inside the chamber and the drying air force.

[0004] Therefore, a sodium-ion battery preparation device and method based on chamber sealing and gas circulation are needed. Summary of the Invention

[0011] Preferably, the buffer door mechanism has a sealing door frame at the bottom side, which is fixed to the top inner side of the base. The sealing door frame has a support groove on its side, and a driven roller is slidably connected inside the support groove. One end of the driven roller has a detachable connecting frame, and the end of the connecting frame is rotatably connected to a support rod. The end of the support rod is rotatably connected to a sealing door. The end of another set of support rods has a sliding sleeve rod for sliding. One end of the sliding sleeve rod is fitted with a limit side plate. The surface of the connecting frame has a rack, and the surface of the rack is meshed with a counterforce gear.

[0015] The method for preparing a sodium-ion battery based on chamber sealing and gas circulation includes the following steps: S1: First, the battery raw materials are placed into the input compartment mechanism. The battery raw materials can be transported intermittently by using the partition plate and the limiting function of the partition groove. The battery raw materials fall onto the positioning conveying mechanism under the action of gravity. At this time, the drive motor drives the first transmission belt and the first transmission shaft to rotate together. By using the integrated fixed structure of the first transmission shaft and the driven gear, the driven gear can drive the connecting chain for transmission. By using the engaging groove, the battery raw materials can be transported intermittently to the second transmission belt. S2: Next, due to the rotation of the motor, the second transmission belt and the second transmission shaft can rotate together to receive the raw material on the locking arc groove, evenly fall into the limiting arc groove and transport it to the buffer door mechanism. The second transmission belt will then send the raw material through the sealed door frame for air drying. S3: Then, the servo motor drives the drive rod to rotate via the third transmission belt. At this time, the anti-force gear fixed to the drive rod rotates in coordination. Utilizing the meshing structure between the anti-force gear and the rack, the rack will synchronously displace the sealing chamber door. The engaging sliding structure between the driven roller and the support slide groove provides a limiting effect. When the sealing chamber door slides, the sliding sleeve will slide in the L-shaped groove in the limiting side plate. When the sliding sleeve slides to the turning point of the groove, it will slide down. At this time, due to the limiting structure, the support diagonal rod will change angle, causing the sealing chamber door to press down and merge with the sealing door frame, thereby reducing the open area of ​​the sealing door frame. Since the buffer door mechanism has an axisymmetric structure design, the rotation of the anti-force gear can drive the two sets of sealing chamber doors to perform reverse lifting operations, realizing the buffer operation of gas leakage. S4: After the battery raw materials enter the sealed chamber, the blower transports gas through the telescopic pipe and blows it down through the air adjustment mechanism to dry the battery raw materials on the conveyor belt. To ensure drying efficiency, the ventilation hole diameter of the air adjustment mechanism can be adjusted. At this time, rotating the connecting top cover can drive the adjusting rod to rotate. Utilizing the connection between the adjusting rod and the drive outer ring, as well as the locking and sliding structure between the limiting groove and the drive outer ring, the rotation of the drive outer ring will drive the rotating sleeve rod connected to the connecting outer rod to rotate. The fixed structure of the rotating sleeve rod and the connecting rod can change the rotation angle of the adjustable fan blades, indirectly changing the ventilation hole diameter, thereby changing the wind force. The air blown into the sealed chamber can be discharged from the air outlet opened on the side of the sealed chamber. S5: After the battery raw materials are dried, they are conveyed to the output chamber by a conveyor belt through another set of buffer door mechanisms. The buffer door mechanism near the output chamber also adopts a double-layer sealed chamber door structure design to prevent a large amount of gas from leaking out and to provide a leakage buffer.

[0016] This invention proposes a sodium-ion battery fabrication device based on chamber sealing and gas circulation. Compared with the prior art, the advantages of this invention are: 1. By setting up a buffer door mechanism, the battery raw materials can be dried while simultaneously buffering gas leakage, ensuring drying efficiency. When driven by the servo motor, the third transmission belt drives the drive rod to rotate. At this time, the anti-force gear fixed to the drive rod will rotate in tandem. The meshing structure of the anti-force gear and the rack allows the rack to move synchronously with the sealing chamber door. Meanwhile, the engaging sliding structure of the driven roller and the support slide groove provides a limiting effect. When the sealing chamber door slides, the sliding sleeve will slide in the L-shaped groove in the limiting side plate. When the sliding sleeve slides to the turning point of the groove, it will slide down. At this time, due to the limiting structure, the angle of the support diagonal rod will change, causing the sealing chamber door to press down and close the sealing door frame, thereby reducing the open area of ​​the sealing door frame. Because the buffer door mechanism has an axisymmetric structure design, the rotation of the anti-force gear can drive the two sets of sealing chamber doors to perform reverse lifting operations, realizing the buffering operation of gas leakage. 2. By setting up an air-adjusting mechanism, the ventilation hole diameter can be adjusted, thereby changing the wind force and ensuring drying efficiency; rotating the connecting top cover can drive the adjusting rod to rotate. Utilizing the connection between the adjusting rod and the drive outer ring, as well as the locking and sliding structure between the limiting groove and the drive outer ring, the rotation of the drive outer ring will drive the rotating sleeve rod connected to the connecting outer rod to rotate. The fixed structure between the rotating sleeve rod and the connecting rod can change the rotation angle of the adjustable fan blades, indirectly changing the ventilation hole diameter, thereby changing the wind force. The air blown into the sealed chamber can be discharged from the air outlet opened on the side of the sealed chamber. 3. By setting up an input chamber mechanism, the battery raw materials can be transported at intervals. When the battery raw materials are placed into the input chamber mechanism, the separation effect of the compartment partition and the limiting effect of the partition arc groove, as well as the setting of the force-bearing rotating shaft off the central axis of the side of the input chamber, will cause the battery raw materials to fall under the action of gravity, while the partition arc groove can transport them at intervals. 4. By setting up a positioning and conveying mechanism, the battery raw materials can be conveyed at intervals. The battery raw materials fall onto the positioning and conveying mechanism under the action of gravity. At this time, the drive motor drives the first transmission belt and the first transmission shaft to rotate together. By utilizing the integrated fixed structure of the first transmission shaft and the driven gear, the driven gear can drive the connecting chain for transmission. By utilizing the interlocking arc groove, the battery raw materials can be conveyed at intervals to the second transmission belt. Attached Figure Description

The end of the third transmission belt 12 is connected to a servo motor 13. The servo motor 13 is located on the top side of the base 1.

[0021] Furthermore, the output end of the motor 3 is provided with a second transmission belt 6 for power transmission. The end of the second transmission belt 6 is connected to a second transmission shaft 7, and the surface of the second transmission shaft 7 is connected to a conveyor belt 8. The surface of the conveyor belt 8 is provided with equidistant limiting arc grooves 9, and the side of the base 1 is provided with an output chamber 10. The rotation of the motor 3 can drive the second transmission belt 6 and the second transmission shaft 7 to rotate together, so as to receive the raw material on the locking arc groove 504, evenly fall into the limiting arc groove 9 and transport it to the buffer door mechanism 11. The equidistant setting of the limiting arc grooves 9 can ensure the drying efficiency.

[0022] Furthermore, a detachable sealed chamber 14 is provided on the inner top of the base 1 above the conveyor belt 8. Air outlets are equidistantly provided on the side of the sealed chamber 14.

A detachable air regulating mechanism 17 is provided inside the connecting top ring 15. A detachable telescopic pipe 18 is provided on the top of the connecting top cover 16. A blower 19 is provided at the end of the telescopic pipe 18. The blower 19 is located on the side of the sealed chamber 14. Rotating the connecting top cover 16 can drive the adjusting rod 1707 to rotate, thereby adjusting the ventilation hole diameter of the air regulating mechanism 17. After the battery raw materials enter the sealed chamber 14, the blower 19 operates to transport gas through the telescopic pipe 18 and blow it down through the air regulating mechanism 17 to dry the battery raw materials on the conveyor belt 8.

[0023] Furthermore, the top of the input chamber mechanism 2 is provided with an input chamber 201, and the bottom inner wall of the input chamber 201 is provided with partition plates 202 at equal intervals. A force-bearing rotating shaft 203 is embedded and connected to the side of the input chamber 201. The force-bearing rotating shaft 203 is set off from the central axis of the side of the input chamber 201. The surface of the force-bearing rotating shaft 203 is provided with partition arc grooves 204 at equal intervals through the partition plates 202. When the battery material is placed into the input chamber mechanism 2, the battery material will fall under the action of gravity due to the partition plate 202, the limiting action of the partition arc grooves 204, and the setting of the force-bearing rotating shaft 203 off from the central axis of the side of the input chamber 201. The partition arc grooves 204 can transport it at intervals.

[0024] Furthermore, the end of the first transmission belt 4 is connected to a first transmission shaft 501. The surface of the first transmission shaft 501 is provided with a detachable driven gear 502. The surface of the driven gear 502 is connected to a connecting chain 503. The outer surface of the connecting chain 503 is provided with equidistant engaging arc grooves 504 for engaging the battery. The battery material falls onto the positioning and conveying mechanism 5 under the action of gravity. Driven by the motor 3, the first transmission belt 4 and the first transmission shaft 501 can rotate together. Utilizing the integrated fixed structure of the first transmission shaft 501 and the driven gear 502, the driven gear 502 can drive the connecting chain 503 for transmission. The engaging arc grooves 504 allow the battery material to be intermittently conveyed to the second transmission belt 6.

[0025] Furthermore, the buffer door mechanism 11 has a sealing door frame 1101 on its side bottom. The sealing door frame 1101 is fixed to the inner top of the base 1. The side of the sealing door frame 1101 has a support groove 1102. A driven roller 1103 is slidably connected inside the support groove 1102. One end of the driven roller 1103 has a detachable connecting frame 1104. The end of the connecting frame 1104 is rotatably connected to a support diagonal rod 1105. The end of the support diagonal rod 1105 is rotatably connected to a sealing door frame 1102. The sealing door 1106 has a sliding sleeve 1107 at the end of another set of supporting diagonal bars 1105 for sliding. One end of the sliding sleeve 1107 is sleeved with a limit side plate 1108. The surface of the connecting frame 1104 is provided with a rack 1109, and the surface of the rack 1109 is meshed with a counterforce gear 1110. The counterforce gear 1110 has a drive rod 1111 fixedly passing through its interior. Both ends of the drive rod 1111 are provided with support frames 1112. When the servo motor 13 drives, the third transmission is used. The belt 12 drives the drive rod 1111 to rotate. At this time, the anti-force gear 1110, which is fixed to the drive rod 1111, rotates in coordination. The meshing structure between the anti-force gear 1110 and the rack 1109 causes the rack 1109 to move synchronously with the sealing door 1106. The engaging sliding structure between the driven roller 1103 and the support slide groove 1102 provides a limiting function. When the sealing door 1106 slides, the sliding sleeve 1107 will slide in the L-shaped groove in the limiting side plate 1108. When the sliding sleeve 1107 slides to the corner of the groove, it will slide down. At this time, due to the limiting structure, the support diagonal bar 1105 will change angle, causing the sealing chamber door 1106 to press down and merge with the sealing door frame 1101, thereby reducing the open area of ​​the sealing door frame 1101. Since the buffer door mechanism 11 has an axisymmetric structure design, the rotation of the counterforce gear 1110 can drive the two sets of sealing chamber doors 1106 to perform reverse lifting operations, realizing the buffer operation of gas leakage.

[0026] Furthermore, the sealed door 1106 is embedded inside the sealed door frame 1101. The interior of the limiting side plate 1108 is provided with an L-shaped groove.

The support frame 1112 is fixed to the surface of the sealed door frame 1101. The end of the drive rod 1111 is connected to the third transmission belt 12. The sliding sleeve 1107 will slide in the L-shaped groove in the limiting side plate 1108. When the sliding sleeve 1107 slides to the turning point of the groove, it will slide down. At this time, due to the limiting structure, the angle of the support diagonal rod 1105 will change, which will drive the sealed door 1106 to press down and merge the sealed door frame 1101, thereby reducing the open area of ​​the sealed door frame 1101.

[0027] Furthermore, the air regulating mechanism 17 has a connecting sleeve 1701 inside, and a connecting rotating rod 1702 on the outer wall of the connecting sleeve 1701. A rotating sleeve rod 1703 with a fixed structure is sleeved on the surface of the connecting rotating rod 1702. A connecting outer rod 1704 is sleeved on one end of the rotating sleeve rod 1703. A driving outer ring 1705 is fixedly connected to one end of the connecting outer rod 1704. A limiting groove 1706 is provided on the top side of the connecting sleeve 1701. A detachable adjusting rod 1707 is provided on the side of the driving outer ring 1705. An adjustable fan blade 1708 is fixedly connected to one end of the connecting rotating rod 1702 that passes through the connecting sleeve 1701. The end is provided with a connecting central shaft 1709; rotating the connecting top cover 16 can drive the adjusting rod 1707 to rotate. Utilizing the connecting action of the adjusting rod 1707 and the driving outer ring 1705, as well as the locking and sliding structure of the limiting groove 1706 and the driving outer ring 1705, the rotation of the driving outer ring 1705 will drive the rotating sleeve rod 1703, which is sleeved with the connecting outer rod 1704, to rotate. The fixed structure of the rotating sleeve rod 1703 and the connecting rotating rod 1702 can change the rotation angle of the adjustable fan blade 1708, indirectly changing the ventilation hole diameter, thereby changing the wind force. The air blown into the sealed chamber 14 can be discharged from the air outlet opened on the side of the sealed chamber 14.

[0028] Furthermore, the rotating sleeve 1703 and the connecting outer rod 1704 form an embedded sliding structure, the limiting groove 1706 and the driving outer ring 1705 form an embedded connection structure, and the adjusting rod 1707 passes through the top of the connecting top cover 16; the rotation of the driving outer ring 1705 will drive the rotating sleeve 1703, which is sleeved with the connecting outer rod 1704, to rotate, and the fixed structure of the rotating sleeve 1703 and the connecting rotating rod 1702 can change the rotation angle of the adjustable fan blade 1708, thereby indirectly changing the ventilation hole diameter and thus changing the wind force; at the same time, by utilizing the structure of the adjusting rod 1707 passing through the connecting top cover 16, the rotation angle of the driving outer ring 1705 can be indirectly adjusted, thereby changing the ventilation hole diameter.

[0029] The method for preparing a sodium-ion battery based on chamber sealing and gas circulation includes the following steps: S1: First, the battery raw materials are placed into the input chamber mechanism 2. The battery raw materials can be transported intermittently by the separation function of the compartment partition 202 and the limiting function of the partition arc groove 204. The battery raw materials fall onto the positioning conveying mechanism 5 under the action of gravity. At this time, the drive motor 3 drives the first transmission belt 4 and the first transmission shaft 501 to rotate together. By utilizing the integrated fixed structure of the first transmission shaft 501 and the driven gear 502, the driven gear 502 can drive the connecting chain 503 for transmission. By utilizing the engaging arc groove 504, the battery raw materials can be transported intermittently to the second transmission belt 6. S2: Next, due to the rotation of the motor 3, the second transmission belt 6 and the second transmission shaft 7 can rotate together to receive the raw material on the locking arc groove 504, evenly fall into the limiting arc groove 9 and transport it to the buffer door mechanism 11. The second transmission belt 6 sends the raw material through the sealing door frame 1101 for air drying. S3: Then, the servo motor 13 drives the drive rod 1111 to rotate via the third transmission belt 12. At this time, the anti-rotation gear 1110 fixed to the drive rod 1111 rotates in coordination. Utilizing the meshing structure between the anti-rotation gear 1110 and the rack 1109, the rack 1109 synchronously displaces the sealing door 1106. The engaging sliding structure between the driven roller 1103 and the support slide groove 1102 provides a limiting function. When the sealing door 1106 slides, the sliding sleeve 1107 will be positioned on the limiting side plate 11. The sliding sleeve 1107 slides within the L-shaped groove in 08. When the sliding sleeve 1107 slides to the turning point of the groove, it will slide down. At this time, due to the limiting structure, the support diagonal bar 1105 will change angle, driving the sealing door 1106 to press down and merge with the sealing door frame 1101, thereby reducing the open area of ​​the sealing door frame 1101. Since the buffer door mechanism 11 has an axisymmetric structure design, the rotation of the counterforce gear 1110 can drive the two sets of sealing doors 1106 to perform reverse lifting operations, realizing the buffer operation of gas leakage. S4: After the battery raw materials enter the sealed chamber 14, the blower 19 operates to transport gas through the telescopic pipe 18 and blow it down through the air adjustment mechanism 17 to air dry the battery raw materials on the conveyor belt 8. To ensure air drying efficiency, the ventilation hole diameter of the air adjustment mechanism 17 can be adjusted. At this time, rotating the connecting top cover 16 can drive the adjusting rod 1707 to rotate. Utilizing the connection between the adjusting rod 1707 and the driving outer ring 1705, as well as the locking and sliding structure between the limiting groove 1706 and the driving outer ring 1705, the rotation of the driving outer ring 1705 will drive the rotating sleeve rod 1703, which is sleeved with the connecting outer rod 1704, to rotate. The fixed structure between the rotating sleeve rod 1703 and the connecting rotating rod 1702 can change the rotation angle of the adjustable fan blade 1708, indirectly changing the ventilation hole diameter, thereby changing the wind force. The air blown into the sealed chamber 14 can be discharged from the air outlet opened on the side of the sealed chamber 14. S5: After the battery raw materials are dried, they are transported to the output chamber 10 by the conveyor belt 8 through another set of buffer door mechanisms 11. The buffer door mechanism 11 near the output chamber 10 also adopts a double-layer sealed chamber door 1106 structure design to prevent a large amount of gas from leaking out and to provide a leakage buffering effect.

[0030] Working principle: First, the battery raw materials are placed into the input chamber mechanism 2. Utilizing the separating function of the compartment partition 202 and the limiting function of the separating arc groove 204, the battery raw materials can be transported intermittently. Under the action of gravity, the battery raw materials fall onto the positioning conveying mechanism 5. At this time, the drive motor 3 drives the first transmission belt 4 and the first transmission shaft 501 to rotate together. Utilizing the integrated fixed structure of the first transmission shaft 501 and the driven gear 502, the driven gear 502 can drive the connecting chain 503 for transmission. Utilizing the engaging arc groove 504, the battery raw materials can be transported intermittently to the second transmission belt 6. Due to the rotation of the motor 3, the second transmission belt 6 and the second transmission shaft 7 can rotate together, receiving the raw materials on the engaging arc groove 504, evenly falling into the limiting arc groove 9 and being transported to the buffer door mechanism 11. The second transmission belt 6 then sends the raw materials through the sealed door frame 1101 for air drying. Next, the servo motor 13 drives the drive rod 1111 to rotate via the third transmission belt 12. At this time, the anti-rotation gear 1110 fixed to the drive rod 1111 rotates in coordination. Utilizing the meshing structure between the anti-rotation gear 1110 and the rack 1109, the rack 1109 synchronously displaces the sealing door 1106. The engaging sliding structure between the driven roller 1103 and the support slide groove 1102 provides a limiting function. When the sealing door 1106 slides, the sliding sleeve 1107 will be positioned on the limiting side plate 110. The sliding sleeve 1107 slides within the L-shaped groove. When the sliding sleeve 1107 slides to the turning point of the groove, it will slide down. At this time, due to the limiting structure, the support diagonal bar 1105 will change angle, causing the sealing door 1106 to press down and merge with the sealing door frame 1101, thereby reducing the open area of ​​the sealing door frame 1101. Since the buffer door mechanism 11 has an axisymmetric structure design, the rotation of the counterforce gear 1110 can drive the two sets of sealing doors 1106 to perform reverse lifting operations, realizing the buffer operation of gas leakage. Then, after the battery raw materials enter the sealed chamber 14, the blower 19 operates to transport gas through the telescopic pipe 18 and blow it down through the air regulating mechanism 17 to air dry the battery raw materials on the conveyor belt 8. To ensure air drying efficiency, the ventilation hole diameter of the air regulating mechanism 17 can be adjusted. At this time, rotating the connecting top cover 16 can drive the adjusting rod 1707 to rotate. Utilizing the connection between the adjusting rod 1707 and the driving outer ring 1705, as well as the locking and sliding structure between the limiting groove 1706 and the driving outer ring 1705, the rotation of the driving outer ring 1705 will drive the rotating sleeve rod 1703, which is sleeved with the connecting outer rod 1704, to rotate. The fixed structure between the rotating sleeve rod 1703 and the connecting rotating rod 1702 can change the rotation angle of the adjustable fan blade 1708, indirectly changing the ventilation hole diameter, thereby changing the wind force. The air blown into the sealed chamber 14 can be discharged from the air outlet opened on the side of the sealed chamber 14. Finally, after the battery raw materials are dried, they are transported to the output chamber 10 by conveyor belt 8 through another set of buffer door mechanisms 11. The buffer door mechanism 11 near the output chamber 10 also adopts a double-layer sealed chamber door 1106 structure design to prevent a large amount of gas from leaking out and to provide a leakage buffering effect.
