Description

Technical Field

[0001] This invention relates to the field of chemical equipment, specifically to a reaction vessel for preparing polyanionic materials. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. The medium inside the reaction vessel is completely contained within a sealed cavity formed by the vessel body and the sealing cover, completely solving the leakage problems of magnetic seals, packing seals, and mechanical seals, ensuring that the reaction medium is completely free from leakage and contamination. However, due to the need for strict control of reaction temperature and pressure during production, it is currently difficult for general reaction vessels to meet these requirements during preparation, resulting in a large number of by-products and consequently reduced purity of the prepared product.

[0003] To address this, Chinese patent CN203807177U discloses a reaction vessel for preparing lithium iron phosphate manganese. It controls the reaction temperature inside the vessel by circulating water through the jacket and controls the reaction pressure inside the vessel by a nitrogen supply unit. Furthermore, the pipeline of the nitrogen supply unit exchanges heat with the circulating water inside the jacket before being introduced into the vessel, thus preventing the sudden change in temperature inside the vessel when nitrogen is introduced, which would lead to an increase in reaction byproducts.

[0004] However, after use, some raw materials remain inside the reactor. Due to the complex structure of the reactor and poor cleaning efficiency, the impurities remaining inside will contaminate the raw materials when used again, thus affecting the purity of the prepared materials.

[0062] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0063] Reference Figures 1-13 A reactor for preparing polyanionic materials includes a high-pressure reactor 1 and a stirring device 2. The high-pressure reactor 1 includes a reactor body 11 and a reactor cover 12. The reactor cover 12 has a feed inlet 121. A water circulation component 13 and a nitrogen communication component 14 are fixedly installed on the reactor cover 12 and are connected to the interior of the reactor body 11. The stirring device 2 includes an explosion-proof motor 21 and a stirring rod 22. The explosion-proof motor 21 is fixedly installed on the reactor cover 12, and the stirring rod 22 is rotatably installed inside the reactor body 11. The drive end of the explosion-proof motor 21 is coaxially and fixedly connected to the stirring rod 22. The reactor also includes a cleaning device 3, which includes a support arm 31, a connecting pipe 32, a nozzle assembly 33, and a linear drive assembly 34. The support arm 31 is slidably installed on the reactor cover 12. The connecting pipe 32 is slidably installed on the support arm 31. The nozzle assembly 33 is fixedly connected to the connecting pipe 32. The linear drive assembly 34 is fixedly installed on the reactor body 11, and the drive end of the linear drive assembly 34 is fixedly connected to the support arm 31.

[0064] This application achieves the function of cleaning the inside of the reactor body 11 through a high-pressure reactor 1, a stirring device 2, and a cleaning device 3. This achieves precise control of the reaction temperature and pressure while reducing impurities inside the reactor body 11, solving the problem that impurities remain inside the reactor body 11 after use, affecting the accuracy of subsequent reactions. The high-pressure reactor 1 is existing technology. A discharge port is provided at the bottom of the reactor body 11. The nitrogen gas connection component 14, the explosion-proof motor 21, and the linear drive component 34 are electrically connected to the controller. The operator injects the reaction raw materials into the reactor body 11 through the feed port 121, and then sends a signal to the explosion-proof motor 21 through the controller. Upon receiving the signal, the stirring rod 22 is driven to rotate, accelerating the mixing uniformity of the raw materials in the reactor. At the same time, the reaction temperature inside the reactor body 11 is controlled by the water circulation component 13, and the reaction pressure inside the reactor body 11 is controlled by the nitrogen connection component 14, achieving a precise reaction effect. After the reaction is completed, the operator sends a signal to the linear drive component 34 through the controller. The linear drive component 34 drives the support arm 31 to move downward, moving the nozzle component 33 into the reactor body 11. Then, the connecting pipe 32 is connected to the water source, and the water flow is sprayed out through the nozzle component 33 to clean the inside of the reactor body 11, reducing the impurities remaining inside the reactor body 11 and further improving the reaction accuracy.

[0065] Reference Figure 1 , Figure 5 , Figure 6 and Figure 8 The system also includes a connecting mechanism 4, which includes multiple connecting components 41. Each connecting component 41 includes a first mounting plate 411, a second mounting plate 412, a first fixing rod 413, and a connecting rod 414. The first mounting plate 411 and the second mounting plate 412 are slidably sleeved on the connecting tube 32. The first mounting plate 411 and the second mounting plate 412 of adjacent connecting components 41 are coaxially rotatably connected. The second mounting plate 412 located at the end of the connecting tube 32 is fixedly sleeved on the connecting tube 32. The first fixing rod 413 is fixedly installed on the first mounting plate 411. The two ends of the connecting rod 414 are respectively hinged to the first fixing rod 413 and the second mounting plate 412. A fixing component 42 for fixing the connecting rod 414 is fixedly installed on the first mounting plate 411.

[0066] This application achieves the function of supporting the connecting rod through the connecting component 41 and the fixing component 42, thus enabling the connecting pipe 32 to have both rigid and flexible states. When cleaning the vessel body 11, the operator sends a signal to the linear drive component 34 through the controller. After receiving the signal, the linear drive component 34 drives the support arm 31 to descend. Since the stirring rod 22 is also installed inside the vessel body 11, the stirring rod 22 will block part of the inner wall of the vessel body 11, forming a cleaning dead corner. For this reason, the connecting component 41 and the fixing component 42 are set up. The operator connects multiple connecting components 41 end to end through the fixing component 42, so that the connecting pipe 32 has rigidity. Then, the connecting rod 414 is controlled to rotate through the fixing component 42, so that the connecting component 41 bends. Through the rigidity of the connecting component 41, the connecting pipe 32 can maintain a fixed angle of extension, thereby eliminating the cleaning dead corner and enhancing the cleaning effect.

[0067] Reference Figure 1 , Figure 5 , Figure 6 and Figure 8 The fixing component 42 includes a sliding mounting plate 421, a first elastic element 422, a guide rail 423, and a second fixing rod 424. The sliding mounting plate 421 is slidably mounted on the connecting pipe 32. The two ends of the first elastic element 422 are fixedly connected to the sliding mounting plate 421 and the first mounting plate 411, respectively. The guide rail 423 is fixedly mounted on the connecting rod 414. The second fixing rod 424 is fixedly mounted on the sliding mounting plate 421, and the second fixing rod 424 and the guide rail 423 are slidably engaged. An automatic control mechanism 5 for controlling the sliding of the sliding mounting plate 421 is also fixedly mounted at the bottom end of the support arm 31.

[0068] This application achieves the function of maintaining the rigidity of the connecting assembly 41 through the sliding mounting plate 421, the first elastic element 422, the guide rail 423, and the second fixing rod 424. Under no external force, the connecting assembly 41 is driven by the elastic force of the first elastic element 422 to slide the sliding mounting plate 421 away from the first mounting plate 411. The sliding mounting plate 421 drives the second fixing rod 424 to slide along the guide rail 423. Supported by the second fixing rod 424, the connecting rod 414 and the first fixing rod 413 are kept on the same straight line, thus keeping the connecting assembly 41 in a straight state. Then, the controller sends a signal to the linear drive assembly 34. Upon receiving the signal, the linear drive assembly 34 drives the support arm 31 to move into the vessel body 11, causing the nozzle assembly 33 to move downwards. Then, the controller... The operator then extends the connecting pipe 32 downwards. At this time, the support arm 31 is in a fixed state. As the connecting pipe 32 extends downwards, it drives multiple connecting components 41 to move downwards synchronously. When the connecting components 41 move to the automatic control mechanism 5, the sliding mounting plate 421 is restricted by the automatic control mechanism 5 and stops sliding. The connecting components 41 continue to move downwards, thereby compressing the first elastic element 422, causing the second fixed rod 424 to slide to the top of the guide rail 423, releasing the rotation restriction on the connecting rod 414, allowing the connecting rod 414 to rotate. Then, the rotation angle of the connecting pipe 32 is controlled by the guiding action of the automatic control mechanism 5. Through the cooperation of the connecting mechanism 4 and the automatic control mechanism 5, the movement flexibility of the connecting pipe 32 is greatly improved, thereby eliminating cleaning dead angles and greatly improving the cleaning effect.

[0069] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The automatic control mechanism 5 includes a bending assembly 51; the bending assembly 51 includes a first mounting base 511, a right-angle slide rail 512, and rollers 513; the first mounting base 511 is fixedly mounted on the end of the support arm 31; the right-angle slide rail 512 is fixedly mounted on the first mounting base 511; multiple rollers 513 are provided and correspond one-to-one with the connecting assembly 41, and the rollers 513 are rotatably mounted on the second fixed rod 424; a control assembly 52 for controlling the sliding of the sliding mounting base is fixedly mounted on the first mounting base 511.

[0070] This application achieves the function of automatically bending the connecting pipe 32 through the bending component 51 and the control component 52. When cleaning the vessel body 11, the operator first sends a signal to the linear drive component 34 via the controller. Upon receiving the signal, the linear drive component 34 drives the support arm 31 to descend. The support arm 31 then moves the first mounting base 511 and the nozzle assembly 33 downwards. After reaching the designated position, water is sprayed out through the connecting pipe 32 and the nozzle to clean the inside of the vessel body 11. Then, the connecting pipe 32 continues to extend, and the connecting pipe 32 drives the connecting component 41 to move synchronously. When the second mounting base 511... When the disk 412 moves to the first mounting base 511, the movement of the sliding mounting disk 421 is restricted by the control component 52, thereby causing relative movement between the sliding mounting disk 421 and the first mounting disk 411, which compresses the first elastic element 422, releasing the restriction on the rotation of the connecting rod 414. Then, the angle of the connecting tube 32 is changed by the guiding action of the right-angle slide rail 512. After the connecting component 41 passes the first mounting base 511, the connecting rod 414 is fixed again by the elastic force of the first elastic element 422, restricting the rotation of the connecting rod 414 and keeping the connecting tube 32 in a straight state.

[0071] Reference Figures 1-9 The control component 52 includes a fixed guide rail 521, a fixed shaft 522, a first slider 523, a second elastic element 524, a second slider 525, and a first limiting block 526. The fixed guide rail 521 is fixedly mounted on the first mounting base 511. The fixed shaft 522 is fixedly mounted on the second fixed rod 424. The first slider 523 is slidably mounted on the fixed guide rail 521. The two ends of the second elastic element 524 are fixedly connected to the first slider 523 and the first mounting base 511, respectively. The second slider 525 is rotatably mounted on the first slider 523. The first limiting block 526 is fixedly mounted on the second slider 525 and slides with the fixed guide rail 521.

[0072] This application achieves the function of automatically restricting the movement of the sliding mounting plate 421 through a fixed guide rail 521, a fixed shaft 522, a first slider 523, a second elastic element 524, a second slider 525, and a first limiting block 526. When cleaning the vessel body 11, the operator first sends a signal to the linear drive assembly 34 via the controller. Upon receiving the signal, the linear drive assembly 34 drives the support arm 31 to descend. The support arm 31 drives the first mounting base 511 and the nozzle assembly 33 to move downwards. After moving to the designated position, water is sprayed out through the connecting pipe 32 and the nozzle to clean the inside of the vessel body 11. Then, the connecting pipe 32 continues to extend, driving the connecting assembly 41 to move synchronously. When the second mounting plate 412 moves to the first mounting base 511, the fixed shaft 522 abuts against the second slide rail. The cooperation of a limiting block 526 with a fixed guide rail 521 causes the second slider 525 to move the first slider 523, compressing the second elastic element 524. The elastic force of the second elastic element 524 counteracts the elastic force of the first elastic element 422, restricting the movement of the sliding mounting plate 421. This causes the first elastic element 422 to compress, releasing the restriction on the rotation of the connecting rod 414. Then, the angle of the connecting tube 32 is changed by the guiding action of the right-angle slide rail 512. As the connecting assembly 41 moves, the sliding mounting plate 421 abuts against the first mounting plate 411. The first mounting plate 411 drives the sliding mounting plate 421 to move. After the connecting assembly 41 passes the first mounting seat 511, the connecting rod 414 is fixed again under the elastic force of the first elastic element 422, restricting the rotation of the connecting rod 414 and keeping the connecting tube 32 in a straight state.

[0073] Reference Figure 3 , Figure 10 and Figure 11 The nozzle assembly 33 includes a second mounting base 331, a third mounting base 332, and a shower head 333. The second mounting base 331 is fixedly connected to the connecting pipe 32. The third mounting base 332 is rotatably mounted on the second mounting base 331. Multiple shower heads 333 are provided, and the multiple shower heads 333 are respectively fixedly mounted on the second mounting base 331 and the third mounting base 332. The spray extension direction of the shower head 333 mounted on the third mounting base 332 is offset from the axis of the third mounting base 332.

[0074] This application achieves the function of all-angle cleaning through the second mounting base 331, the third mounting base 332 and the shower head 333, thereby increasing the spray angle of the shower head. After the water source is turned on, the water flows through the connecting pipe 32 and sprays out from the shower head 333. With the impact of the water flow, the third mounting base 332 rotates on the second mounting base 331. The rotation of the third mounting base 332 makes the spray angle more comprehensive and further improves the cleaning effect.

[0075] Reference Figure 3 , Figure 11 , Figure 12 and Figure 13 It also includes a sensing device 6, which includes a first pressure sensor 61, a third elastic element 62, and an annular protective frame 63; the first pressure sensor 61 is fixedly mounted on the second mounting frame; the two ends of the third elastic element 62 are fixedly connected to the first pressure sensor 61 and the annular protective frame 63 respectively; the annular protective frame 63 is located on the outside of the second mounting frame.

[0076] This application achieves the function of protecting the nozzle assembly 33 through the first pressure sensor 61, the third elastic element 62, and the annular protective frame 63, thereby preventing the nozzle assembly 33 from colliding with objects inside the vessel body 11. The first pressure sensor 61 is electrically connected to the controller. As the operator moves the connecting pipe 32, the moving pipe drives the nozzle assembly 33 to move synchronously. Before the nozzle assembly 33 comes into contact with the objects inside the vessel body 11, the annular protective frame 63 will first make contact with them. Then the third elastic element 62 is compressed, converting the collision force into internal energy and buffering the impact caused by the collision. The first pressure sensor 61 senses the pressure change and feeds back a signal to the controller. The controller stops driving the support arm 31 to move and reminds the operator. The operator stops moving the connecting pipe 32, thereby protecting the nozzle assembly 33 and other parts inside the vessel body 11.

[0077] Reference Figure 3 , Figure 11 , Figure 12 and Figure 13 The sensing device 6 also includes a fourth elastic element 64, a protective ring 65, and a second pressure sensor 66; the two ends of the fourth elastic element 64 are fixedly connected to the annular mounting bracket and the second pressure sensor 66 respectively; the second pressure sensor 66 is fixedly mounted on the protective ring 65; the protective ring 65 is located at the bottom of the annular protective bracket 63.

[0078] This application achieves further protection for the nozzle assembly 33 through the fourth elastic element 64, the protective ring 65, and the second pressure sensor 66. The second pressure sensor 66 is electrically connected to the controller. When the operator moves the nozzle assembly 33, if the bottom of the nozzle assembly 33 comes into contact with other objects inside the vessel 11, the nozzle assembly 33 may not be able to penetrate into the vessel 11 properly, resulting in incorrect cleaning position and affecting the cleaning effect. Furthermore, when the shower head 333 collides with parts inside the vessel 11, it may cause damage to them, affecting subsequent use. Therefore, a protective ring 65 is provided at the bottom of the annular protective frame 63. Before the nozzle assembly 33 comes into contact with objects inside the vessel 11, the protective ring 65 will first contact them, thereby compressing the fourth elastic element 64. Then, the second pressure sensor 66 detects the pressure change and feeds back a signal to the controller so that the controller can react in a timely manner.

[0079] Reference Figure 2 and Figure 3The linear drive assembly 34 includes a linear driver 341 and a fixing block 342; the linear driver 341 is fixedly mounted on the vessel body 11, and the drive end of the linear driver 341 is fixedly connected to the fixing block 342; the fixing block 342 is fixedly connected to the support arm 31.

[0080] This application realizes the function of driving the support arm 31 to move through the linear actuator 341 and the fixed block 342; the linear actuator 341 is preferably a hydraulic rod, and the linear actuator 341 is electrically connected to the controller; the operator sends a signal to the linear actuator 341 through the controller, and after receiving the signal, the linear actuator 341 drives the fixed block 342 and the support arm 31 to move, thereby driving the nozzle assembly 33 to move into the inside of the vessel 11 to clean the vessel 11.

[0081] Reference Figures 1-3 The cleaning device 3 also includes a limiting component 35, which includes a limiting rod 351 and a second limiting block 352.
