Description

Technical Field

[0001] This invention relates to the field of atmosphere control technology for high-temperature sintering vacuum reactors for lithium battery materials, and more specifically, to a circulating atmosphere system for a high-temperature vacuum reactor. Background Technology

[0002] The high-temperature vacuum reactor for sintering lithium battery materials is used to perform vacuum high-temperature sintering of materials. It requires the introduction of a protective atmosphere and a special atmosphere, which puts the sealing performance of the vacuum reactor to a severe test.

[0003] The high-temperature sintering reaction of lithium battery materials requires extremely high atmospheric purity. The atmosphere inside the high-temperature reactor must be free of reactive gases such as air and oxygen; instead, an inert protective gas and the necessary reaction gases must be introduced. The protective atmosphere, such as nitrogen or argon, does not produce a reaction and is subsequently extracted by the vacuum pump after being introduced into the reactor, resulting in waste. The high-temperature vacuum reactor for lithium battery materials requires a certain degree of vacuum, placing extremely high demands on sealing. The vacuum mechanical seal of the rotating shaft poses a risk of leakage, and under high vacuum conditions, the sealing material can become permeable, allowing air to enter the reactor and affect the material reaction. Therefore, it is necessary to propose a circulating atmosphere system for a high-temperature vacuum reactor to at least partially solve the problems existing in the current technology.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This invention provides a circulating atmosphere system for a high-temperature vacuum reactor. The circulating atmosphere system includes a main body comprising a cooler, a dust collector, a vacuum pump, a protective atmosphere section, and a reaction atmosphere section connected sequentially. During operation, the vacuum pump is first activated, and it evacuates the high-temperature reactor through the dust collector, creating a vacuum inside the reactor to facilitate high-temperature sintering. A stirring shaft, powered by external force, stirs the interior of the reactor. The protective atmosphere section provides inert protective gas to the gas sealing module, filling it with this gas. In case of leakage, the inert protective gas will enter the high-temperature reactor. The leakage status of the gas sealing module can be determined by monitoring the gas flow rate. This structural design uses inert protective gas to isolate external air, preventing air from entering the high-temperature reactor and ensuring the safe and stable operation of the sintering high-temperature vacuum reactor.

[0017] 2. This invention provides a circulating atmosphere system for a high-temperature vacuum reactor. This system uses a vacuum pump to extract air from the inside of the high-temperature reactor, which is then treated and discharged through a tail gas treatment device. The reaction atmosphere section provides the reaction gases required for the reaction into the high-temperature reactor, while the protective atmosphere section also provides inert protective gases. During operation, the vacuum pump extracts the mixed gas (remaining reaction gas and inert protective gas) from the high-temperature reactor and removes impurities. The inert protective gas is then transported back to the high-temperature reactor along with the inert protective gas provided by the protective atmosphere section. This allows for the reuse of the inert protective gas in the circulating atmosphere system, reducing production costs.

[0018] The high-temperature vacuum reactor circulating atmosphere system of the present invention, other advantages, objectives and features of the present invention will be apparent in part from the following description, and in part will be understood by those skilled in the art through study and practice of the present invention.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0029] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0030] like Figures 1-2 As shown, the present invention provides a high-temperature vacuum reactor circulating atmosphere system, comprising: a circulating atmosphere system body 100, which includes a cooler 2, a dust collector 3, a vacuum pump 4, a protective atmosphere section 7, and a reaction atmosphere section 8 connected in sequence. Here, a high-temperature reactor 1 is installed between the cooler 2 and the reaction atmosphere section 8, and the cooler 2 is connected to the high-temperature reactor 1. The reaction atmosphere section 8 is also connected to the high-temperature reactor 1. A tail gas treatment device 5 is installed between the vacuum pump 4 and the protective atmosphere section 7. In order to seal and protect the high-temperature reactor 1, a gas sealing module is installed on the stirring shaft 101 of the high-temperature reactor 1, and the gas sealing module is connected to the protective atmosphere section 7.

[0031] Therefore, when using it, the vacuum pump 4 is started first. The vacuum pump 4 evacuates the high-temperature reactor 1 through the dust collector 3, so that the inside of the high-temperature reactor 1 is in a vacuum state, so as to facilitate high-temperature sintering. The stirring shaft 101 stirs the inside of the high-temperature reactor 1 under the action of external power. The protective atmosphere section 7 provides inert protective gas to the gas sealing module, so that the gas sealing module is filled with inert protective gas 71. When a leak occurs, the inert protective gas will enter the high-temperature reactor 1. Then, the leakage of the gas sealing module can be judged according to the gas flow rate of the gas sealing module.

[0032] Through the design of the above structure, an inert protective gas is used to isolate the external air, preventing air from entering the high-temperature reactor 1, so that the sintering high-temperature vacuum reactor can operate safely and stably.

[0033] In this process, vacuum pump 4 extracts the air from inside the high-temperature reactor 1 and discharges it after treatment by tail gas treatment device 5. Meanwhile, reaction atmosphere section 8 provides the reaction gas required for the reaction into the high-temperature reactor 1, and protective atmosphere section 7 also provides inert protective gas into the high-temperature reactor 1. During the operation of the high-temperature reactor 1, vacuum pump 4 extracts the mixed gas (remaining reaction gas and inert protective gas) in the high-temperature reactor 1 and, after impurity removal treatment, transports the inert protective gas together with the inert protective gas provided by protective atmosphere section 7 back to the high-temperature reactor 1. This enables the recycling of inert protective gas in the circulating atmosphere system and reduces production costs.

[0034] Exemplary gas sealing module

[0035] Furthermore, some embodiments of the present invention provide a specific structure of a gas sealing module, which includes an inner sealing device 102, a protective gas cover 103, and a sealing protection control valve 33. The inner sealing device 102 is installed on the stirring shaft 101. Here, the inner sealing device 102 can be a mechanical seal device in the prior art, so that there are more models to choose from, thereby reducing costs.

[0036] The protective gas hood 103 is sealed and installed on the upper end of the high-temperature reactor 1 and fitted onto the inner sealing device 102. The protective gas hood 103 provides an external seal to the inner sealing device 102. The protective gas hood 103 is connected to the protective atmosphere section 7, and a sealing protection control valve 33 is installed between the protective gas hood 103 and the protective atmosphere section 7. When the sealing protection control valve 33 is opened, the protective atmosphere section 7 provides inert protective gas into the protective gas hood 103. When the inner sealing device 102 leaks, the inert protective gas filling the protective gas hood 103 enters through the inner sealing device 102, and the gas flow rate changes through the sealing protection control valve 33. Therefore, the leakage of the inner sealing device 102 can be judged based on the gas flow rate of the sealing protection control valve 33.

[0037] Through the design of the above structure, an inert protective gas is used to isolate the external air, preventing air from entering the high-temperature reactor 1, so that the sintering high-temperature vacuum reactor can operate safely and stably.

[0038] Furthermore, a first main pipeline 91 is installed between the protective atmosphere section 7 and the high-temperature reactor 1. The protective atmosphere section 7 is connected to the first main pipeline 91 via a first branch pipeline 92. Simultaneously, the gas sealing module is connected to the first main pipeline 91 via the first branch pipeline 92. Therefore, the inert protective gas provided by the protective atmosphere section 7 enters the first branch pipeline 92 through the first main pipeline 91, and then enters the protective gas hood 103. The aforementioned sealing protection control valve 33 is installed on the first branch pipeline 92, allowing it to monitor the flow rate of the inert protective gas and thus determine the leakage status of the inner sealing device 102.

[0039] Furthermore, in some embodiments of the present invention, the reaction atmosphere section 8 is connected to the first main pipeline 91 via a second branch pipeline 93. A reaction atmosphere control valve 31 is installed on the second branch pipeline 93, and a protective atmosphere control valve 32 is also installed on the first main pipeline 91. The protective atmosphere control valve 32 is located in front of the first branch pipeline 92. Therefore, after the protective atmosphere control valve 32 is activated, the inert protective gas provided in the protective atmosphere section 7 can continue to enter the first main pipeline 91 through the protective atmosphere control valve 32, until it enters the high-temperature reactor 1.

[0040] When the reaction atmosphere control valve 31 is activated, the reaction gas supplied in the reaction atmosphere section 8 enters the first main pipeline 91 through the reaction atmosphere control valve 31, and then enters the high-temperature reactor 1 through the first main pipeline 91. Through the design of the above structure, the inert protective gas and the reaction gas are transported, providing protection for the high-temperature reactor 1.

[0041] Furthermore, in some embodiments of the present invention, the protective atmosphere section 7 is connected to the first main pipeline 91 via a third branch pipeline 94. Here, a first one-way valve 36 is installed on the aforementioned third branch pipeline 94. Therefore, when the first one-way valve 36 is activated, the inert protective gas in the protective atmosphere section 7 enters the first main pipeline 91 through the first one-way valve 36 and is transported to the high-temperature reactor 1 for protection.

[0042] Furthermore, in some embodiments of the present invention, a second main pipeline 95 is installed between the vacuum pump 4 and the protective atmosphere section 7. A fourth branch pipeline 96 and a fifth branch pipeline 97 are also installed on the second main pipeline 95. A second one-way valve 37 is installed on the fourth branch pipeline 96, and an exhaust control valve 35 is installed on the fifth branch pipeline 97. The ends of the fourth branch pipeline 96 and the fifth branch pipeline 97 are connected to the exhaust gas treatment device 5. Furthermore, a circulation pressure reducing control valve 34 and an atmosphere impurity removal filter 6 are respectively provided on the second main pipeline 95, located behind the fourth branch pipeline 96.

[0043] Based on the above structural design, the gas can be recycled according to whether the gas after the reaction can be recycled. The gas discharge or recycling is controlled by the circulation pressure reducing control valve 34 and the exhaust control valve 35. During recycling, the amount and pressure of the recycled gas are controlled by the circulation pressure reducing control valve 34. Excess recycled gas can be discharged through the second one-way valve 37. The recycled gas passes through the atmosphere impurity removal filter 6 to remove gases and impurities that affect the reaction, and is then connected back to the second main pipeline 95 and the first main pipeline 91 for recycling.

[0044] Exemplary explosion-proof internal module

[0045] During use, the internal pressure of the aforementioned high-temperature reactor 1 inevitably becomes excessive. If the explosion-proof performance of the current high-temperature reactor is inadequate, it is prone to explosion during processing, generating explosive fragments that could harm personal safety and property. Therefore, it is necessary to improve the aforementioned high-temperature reactor to further enhance the safety of the processing.

[0046] like Figures 3-7 As shown, further, some embodiments of the present invention provide a specific structure of the high-temperature reactor 1. The high-temperature reactor 1 of this structure includes an outer reactor body 11, an inner reactor body 12, and an explosion-proof inner module 13. Specifically, the inner reactor body 12 is installed inside the outer reactor body 11, making the high-temperature reactor 1 a double-layer structure. Moreover, an explosion-proof inner module 13 is installed between the outer reactor body 11 and the inner reactor body 12. The explosion-proof inner module 13 further protects the high-temperature reactor 1 to prevent the entire high-temperature reactor 1 from bursting and damaging personal and property safety in the event of an explosion.

[0047] The explosion-proof inner module 13 includes a first steel wire layer 14, a second steel wire layer 15, and multiple node support parts 16. The first steel wire layer 14 and the second steel wire layer 15 are installed between the outer vessel body 11 and the inner vessel body 12. Specifically, the first steel wire layer 14 is installed on the inner wall of the outer vessel body 11, and the second steel wire layer 15 is installed on the inner wall of the inner vessel body 12. The multiple node support parts 16 are all arranged between the first steel wire layer 14 and the second steel wire layer 15 to provide internal support for the first steel wire layer 14, the second steel wire layer 15, and the outer vessel body 11 and the inner vessel body 12. Furthermore, to further enhance the explosion-proof performance of the above structure, the first steel wire layer 14 and the second steel wire layer 15 are positioned between... Two explosion-proof inner membrane layers 140 are also installed, with a polyurethane foam layer 10 filling between them. The first steel wire layer 14 and the second steel wire layer 15 serve as fixing mechanisms to secure the two explosion-proof inner membrane layers 140 and the polyurethane foam layer 10. The two explosion-proof inner membrane layers 140 can bond and fix the first steel wire layer 14 and the second steel wire layer 15, greatly increasing their impact resistance. The node support part 16 supports the entire explosion-proof inner module 13, increasing its impact resistance during explosions. This achieves the above-mentioned goal of preventing the entire high-temperature reactor 1 from rupturing and generating explosive fragments that could damage personal and property safety in the event of an explosion.

[0048] Furthermore, the aforementioned node support 16 includes a first vertical explosion-proof plate 17, a second vertical explosion-proof plate 18, multiple horizontal telescopic rods 19, a first explosion-proof guide group 20, and a second explosion-proof guide group 21. The first vertical explosion-proof plate 17 is installed on the first steel wire layer 14, while the second vertical explosion-proof plate 18 is installed on the second steel wire layer 15. Multiple horizontal telescopic rods 19 are installed between the first vertical explosion-proof plate 17 and the second vertical explosion-proof plate 18. Therefore, when the first steel wire layer 14 is impacted, the impact force can be transferred to the first vertical explosion-proof plate 17, thereby... A vertical explosion-proof plate 17 transmits the energy to a second vertical explosion-proof plate 18 through multiple horizontal telescopic rods 19. To reduce the energy of the impact, a first explosion-proof guide group 20 is installed on the inner wall of the first vertical explosion-proof plate 17, and a second explosion-proof guide group 21 is installed on the inner wall of the second vertical explosion-proof plate 18. The second explosion-proof guide group 21 is movably connected to the multiple horizontal telescopic rods 19. Therefore, the impact force is offset synchronously by the multiple horizontal telescopic rods 19, the first explosion-proof guide group 20, and the second explosion-proof guide group 21 to reduce the impact on the outer vessel body 11. Furthermore, protective rings 160 are installed on the inner walls of the first vertical explosion-proof plate 17 and the second vertical explosion-proof plate 18, and a protective telescopic cover 161 is installed between the two protective rings 160. The protective telescopic cover wraps around the above-mentioned multiple horizontal telescopic rods 19, the first explosion-proof guide group 20, and the second explosion-proof guide group 21 to prevent the impact polyurethane foam layer 10 from interfering with the above-mentioned components, thereby increasing the overall protective performance of the explosion-proof inner module 13.

[0049] Furthermore, in some embodiments of the present invention, a specific structure of the first explosion-proof guide assembly 20 is provided. This structure of the first explosion-proof guide assembly 20 is used to offset the impact force transmitted by the first vertical explosion-proof plate 17. Specifically, the first explosion-proof guide assembly 20 includes a first elastic guide seat 201, a second elastic guide seat 202, a guide telescopic rod 203, and multiple guide frames 204. Here, the first elastic guide seat 201 is installed on the inner wall of the first vertical explosion-proof plate 17, while the second elastic guide seat 202... The guide seat 202 is installed on the second explosion-proof guide group 21. So when the first explosion-proof guide group 20 is impacted, the first elastic guide seat 201 moves toward the second elastic guide seat 202. Since a guide telescopic rod 203 is installed between the two, the guide inner rod 2031 in the guide telescopic rod 203 moves along the guide inner cylinder 2032 to provide guidance for the movement of the first elastic guide seat 201 and prevent the first elastic guide seat 201 from tilting. Therefore, the movement stability of the first explosion-proof guide group 20 is increased.

[0050] Furthermore, multiple guide frames 204 are evenly distributed on the inner wall of the first vertical explosion-proof plate 17 and located around the first elastic guide seat 201. Therefore, during the movement of the first elastic guide seat 201, it squeezes the guide frame 204, so the first guide roller 205 on the vertical telescopic guide rod 2041 slides and moves on the convex outer guide wall of the first elastic guide seat 201. As the first elastic guide seat 201 moves, the vertical telescopic guide rod 2041 contracts. Similarly, the second elastic guide seat 202 also squeezes the vertical telescopic guide rod 2041, so the first guide roller 205 on the vertical telescopic guide rod 2041 contracts. The roller 205 slides along the convex outer guide wall of the second elastic guide seat 202. As the second elastic guide seat 202 moves, the vertical telescopic guide rod 2041 contracts. Through the design of the above structure, the lateral impact energy generated inside is converted from the lateral direction to the vertical direction, so as to reduce the lateral impact energy from continuing to impact the outer vessel body 12. Even if the top of the outer vessel body 12 bursts, the safety of the entire high-temperature reactor 1 in the lateral direction is greatly increased, preventing the outer vessel body 12 from generating explosive fragments in the lateral direction when the high-temperature reactor 1 explodes, thus preventing personal and property safety from being damaged.

[0051] Furthermore, in some embodiments of the present invention, the second explosion-proof guide assembly 21 includes an intermediate explosion-proof seat 211, a plurality of first inclined guide rods 212, an inner moving plate 213, an inner spring 214, and a plurality of second inclined guide rods 215. The intermediate explosion-proof seat 211 is installed on the inner wall of the second vertical explosion-proof plate 18, and the second elastic guide seat 202 is installed on the intermediate explosion-proof seat 211. A plurality of chamfered holes 216 are provided on the intermediate explosion-proof seat 211. The inner moving plate 213 is installed inside the intermediate explosion-proof seat 211 and connected to the inner spring 214. One end of the first inclined guide rod 212 passes through the chamfered hole 216 and is hinged to the inner moving plate 213, and the other end is hinged to the transverse telescopic rod 19. One end of the second inclined guide rod 215 is hinged to the intermediate explosion-proof seat 211.

[0052] Therefore, when the transverse telescopic rod 19 and the second explosion-proof guide assembly 21 are impacted, the transverse telescopic rod 19 retracts, and the second explosion-proof guide assembly 21, after being impacted by the retraction of the transverse telescopic rod 19, pushes the inner moving plate 213 through the guide hole 216. The inner moving plate 213 pulls the inner spring 214 and simultaneously compresses the second inclined guide rod 215. The inner spring 214 helps the inner moving plate 213 return to its original position, while the second inclined guide rod 215 slides along the inner wall of the intermediate explosion-proof seat 211. In the middle, the other end of the second inclined guide rod 215 is equipped with a second guide roller body 217. Therefore, the second guide roller body 217 provides a guiding function for the second inclined guide rod 215, making the movement of the inner moving plate 213 very stable. It can also convert the lateral impact energy generated inside from the lateral direction to the vertical direction, thereby further cooperating with the conversion function of the first explosion-proof guide group 20. This greatly increases the safety of the high-temperature reactor 1 and prevents the outer vessel body 12 from generating explosive fragments in the lateral direction when the high-temperature reactor 1 explodes, thus protecting personal and property safety.

[0053] Furthermore, some embodiments of the present invention provide a specific structure for the transverse telescopic rod 19. This transverse telescopic rod 19 includes a transverse inner cylinder 191, a transverse inner rod 192, a transverse spring 193, and a fixing cylinder 194. Here, the fixing cylinder 194 is installed on the inner wall of the second vertical explosion-proof plate 18, while the transverse inner cylinder 191 is installed within the fixing cylinder 194. The fixing cylinder 194 provides fixed support for the transverse inner cylinder 191, preventing it from tilting. One end of the transverse inner rod 192 is connected to the inner wall of the first vertical explosion-proof plate 17, and the other end is connected to the transverse inner cylinder 191. 1. The transverse spring 193 is installed on the transverse inner rod 192 and abuts against the transverse inner cylinder 191. So when the transverse inner rod 192 moves toward the transverse inner cylinder 191, it compresses the transverse spring 193, and the transverse spring 193 generates elastic force to offset the impact energy. An outer hinge block 195 is installed on the transverse inner rod 192. The other end of the first inclined guide rod 212 is connected to the outer hinge block 195. So when the transverse inner rod 192 moves, it drives the outer hinge block 195 to move, and also allows the first inclined guide rod 212 to move toward the middle explosion-proof seat 211.

[0054] The aforementioned transverse telescopic rod 19 is used in conjunction with the second explosion-proof guide group 21, so that the node support part 16 can convert the transverse impact energy generated inside from the transverse direction to the vertical direction, thereby reducing the transverse impact energy from continuing to impact the outer vessel body 12. This greatly increases the safety of the high-temperature reactor 1 and prevents the outer vessel body 12 from generating explosive fragments in the transverse direction when the high-temperature reactor 1 explodes, thus preventing personal and property safety from being damaged.

[0055] Furthermore, the circulating atmosphere system of the high-temperature vacuum reactor of the present invention also has a variety of control schemes, such as: (1) pre-vacuum upon startup; (2) both reaction atmosphere and protective atmosphere are required and can be circulated; (3) both reaction atmosphere and protective atmosphere are required and cannot be circulated; (4) only protective atmosphere is required and can be circulated; (5) only protective atmosphere is required and cannot be circulated.

[0056] (1) Pre-vacuuming upon startup: The purpose is to purge the air from the high-temperature reactor 1, the sealing structure, all equipment and pipelines; after the material is put in, start the machine and only pump in the protective atmosphere section 7, open the protective atmosphere control valve 32, the sealing protection control valve 33 and the exhaust control valve 35, open the exhaust valve 104, purge the air from the protective gas cover 103 and then close it, start the vacuum pump 4 to purge the air from the high-temperature reactor 1, check the concentration of the exhaust gas outlet atmosphere, and after it reaches the requirement, open the circulation pressure reducing control valve 34 for a period of time and then close it to purge the remaining air in the pipeline, check the oxygen content in the high-temperature reactor 1 and after it reaches the requirement, proceed to the next production step.

[0057] (2) The reaction atmosphere and protective atmosphere need to be circulated: After the pre-vacuum is turned on, the reaction atmosphere control valve 31 is opened to control the amount of reaction atmosphere injected into the reaction atmosphere section 8, the exhaust control valve 35 is closed, and the circulation pressure reduction control valve 34 is opened to circulate the atmosphere. The atmosphere after the reaction passes through the atmosphere impurity removal filter 6 to adsorb and remove the gases that affect the reaction, so that the gas meets the requirements for recycling. When the circulating gas is detected to be unqualified, the exhaust control valve 35 is opened and the circulation pressure reduction control valve 34 is closed to discharge the unqualified gas to the tail gas treatment device 5 for discharge.

[0058] (3) The reaction atmosphere and protective atmosphere need to be non-circulating. The gas injection method is the same as in (2). Open the exhaust control valve 35, close the circulation pressure reducing control valve 34, and discharge the gas to the tail gas treatment device 5 for discharge.

[0059] (4) Only the protective atmosphere can be recycled: the same as (2), but without injecting the reaction atmosphere into section 8.

[0060] (5) Only the protective atmosphere is non-recyclable: Same as (2), but the reaction atmosphere is not injected into section 8.

[0061] Furthermore, during dynamic vacuuming, the flow rate of gas injected into the high-temperature reactor 1 is controlled by the reaction atmosphere control valve 31 and the protective atmosphere control valve 32. The injection rate is much smaller than the pumping rate of the vacuum pump 4 in order to achieve a vacuum state.

[0062] Leakage detection under sealed atmosphere protection: Open the sealing protection control valve 33 and the exhaust control valve 35, open the exhaust valve 104, and close the protective gas cover 103 after the air is exhausted. When the inner sealing device 102 is working normally, there will be a small amount of leakage. When the inner sealing device 102 is damaged and leaks, the leakage will increase. The flow rate change is detected by the protective atmosphere control valve 32 to determine whether the inner sealing device 102 is leaking. When the inner sealing device 102 leaks, the system controls and reduces the amount of air injected by the protective atmosphere control valve 32 to keep the total flow rate of the protective atmosphere control valve 32 and the sealing protection control valve 33 consistent, so as to prevent the vacuum degree in the high-temperature reactor 1 from changing significantly and affecting the material reaction.
