Description

Technical Field

[0001] This invention relates to the field of reaction vessels, specifically a high-temperature powder reaction vessel. Background Technology

[0002] A reaction vessel is a specialized chemical pressure vessel that provides a sealed reaction chamber and integrates functions such as heating, cooling, stirring, and transmission to complete physical or chemical reactions between materials. Many powder raw materials undergoing chemical reactions are processed using reaction vessels.

[0003] However, when existing reactors process powder raw materials for reaction, some powder will continuously contact the high-temperature inner wall of the reactor. This part of the powder is prone to overheating and sintering due to prolonged heating. The sintered powder will interfere with the overall reaction process of the powder, ultimately resulting in poor material reaction uniformity and poor reaction effect. Summary of the Invention

[0007] Preferably, the rotation control component includes a side plate shaft fixedly installed at the other end of the side deflector plate, the side plate shaft penetrating into the interior of the scraper, the side plate shaft rotatably engaging with the scraper, a side gear coaxially fixedly installed at the end of the side plate shaft, a vertical toothed plate slidably installed inside the scraper, the side gear meshing with the vertical toothed plate, the upper end of the vertical toothed plate extending into the interior of the cover, a bottom plate shaft fixedly installed at the upper end of the bottom deflector plate, the bottom plate shaft penetrating into the interior of the main stirring blade, the bottom plate shaft rotatably engaging with the main stirring blade, a bottom gear coaxially fixedly installed at the end of the bottom plate shaft, a horizontal toothed plate slidably installed inside the main stirring blade, the bottom gear meshing with the horizontal toothed plate.

[0008] Preferably, a pressure frame is slidably installed inside the connecting shell, the pressure frame extends through the upper end of the connecting shell, a first push plate frame is rotatably installed at the lower end of the pressure frame, the end of the first push plate frame is rotatably connected to the horizontal toothed plate, a synchronization ring is fixedly installed at the upper end of the pressure frame, the synchronization ring is located outside the stirring shaft, the synchronization ring is coaxial with the stirring shaft, a synchronization frame is rotatably installed on the outer surface of the synchronization ring, and the end of the synchronization frame is fixed to the vertical toothed plate.

[0009] Preferably, a shaft bracket extends from the lower side of the bushing, and a wheel axle is rotatably mounted through the end of the shaft bracket. A control gear is coaxially fixedly mounted on the upper end of the wheel axle. A gear ring is coaxially fixedly mounted on the lower end of the vessel cover. The gear ring is located outside the bushing, and the control gear meshes with the gear ring. A push frame lug is fixedly mounted on the lower end of the wheel axle. A reciprocating frame is rotatably mounted on the end of the push frame lug. A reciprocating frame is rotatably mounted on the end of the reciprocating frame. A second push plate frame is rotatably mounted on the side of the reciprocating frame. The end of the second push plate frame is rotatably connected to one of the vertical toothed plates.

[0010] Preferably, a connecting plate is rotatably mounted through the lower middle part of the cover, and the stirring shaft and the connecting shell pass through the connecting plate, and the stirring shaft and the connecting shell are fixed to the connecting plate.

[0011] Preferably, the inner side of the housing has two guide rails extending symmetrically, and the reciprocating frame is slidably mounted on the outer surface of the guide rails.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The scraper can clean the powder on the inner wall of the vessel. During this process, the side baffle will rotate continuously to push the powder on the inner wall toward the center of the vessel, so that the powder on the inner wall can be replaced. Similarly, when the main stirring blade rotates to stir the powder at the bottom of the vessel, the bottom baffle will rotate continuously to push the powder at the bottom upward, so that the powder at the bottom can be replaced. This changes the contact object between the powder and the inner wall of the vessel, avoiding the same part of the powder from continuously contacting the high-temperature inner wall, thereby reducing the overheating and sintering of the powder due to prolonged heating, and thus improving the reaction effect.

[0014] 2. When the bushing drives the scraper to rotate, the control gear is synchronously driven by the bushing to rotate in a circular motion. At this time, the control gear will roll on the gear ring to rotate, thereby driving the push frame ear to rotate and push the reciprocating frame to move. This allows the reciprocating frame to slide back and forth, which in turn drives the second push plate frame to move and push the vertical toothed plate to slide back and forth, allowing the side gear to rotate. This, in turn, drives the side deflector plate on the side plate shaft to rotate. During this process, the vertical toothed plate sliding back and forth will also drive the pressure frame to move synchronously. The moving pressure frame pushes the first push plate frame to move, allowing the horizontal toothed plate to slide back and forth, allowing the bottom gear to rotate. This, in turn, drives the bottom deflector plate on the bottom plate shaft to rotate. When the scraper on the bushing is rotated by the second geared motor for cleaning, the side deflector plate on the scraper and the bottom deflector plate on the main stirring blade can be rotated synchronously. No additional electrical components need to be installed and operated separately, which effectively simplifies the operation steps and makes it convenient to use. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: such as Figures 1-8The high-temperature powder reaction vessel shown includes a vessel body 1, a vessel cover 2 at the upper end of the vessel body 1, a bushing 6 rotatably mounted through the middle of the vessel cover 2, and a stirring shaft 5 rotatably mounted coaxially inside the bushing 6. The bushing 6 and the stirring shaft 5 rotate in opposite directions to increase the stirring force and promote the reaction of the powder. The two ends of the stirring shaft 5 extend through the upper and lower ends of the bushing 6. A connecting shell 12 is fixedly mounted on the lower part of one side of the stirring shaft 5, serving as a guide. The lower end of the connecting shell 12 is fixedly connected to a main stirring blade 1. 3. The main stirring blade 13 can agitate the powder and scrape the bottom inner wall of the vessel body 1. The lower outer side of the bushing 6 is connected to a cover 8, which serves as a protective cover. The cover 8 is rotatably connected to the vessel lid 2. The lower end of the cover 8 is symmetrically fixed with two scrapers 9. The scrapers 9 can agitate the powder and scrape the side inner wall of the vessel body 1. Multiple side baffles 27 are linearly arrayed and rotatably installed on opposite sides of the two scrapers 9. One end of the side baffles 27 extends with a side arc-shaped plate 35. The side baffles 27 can block the powder, allowing it to be fully moved by the powder. Multiple bottom baffles 14 are rotatably mounted in a linear array on opposite sides of the front and rear ends of the main stirring blades 13. The lower end of each bottom baffle 14 extends a bottom arc-shaped plate 36, which blocks the powder, allowing it to be fully moved by the bottom baffles 14. A rotation control element is provided between the bushing 6 and the bottom baffles 14 and side baffles 27. The scraper 9 can scrape the powder from the inner wall of the vessel body 1. During this process, the side baffles 27... The 7 will rotate continuously to push the powder on the inner wall toward the center of the vessel 1, so that the powder on the inner wall can be replaced. Similarly, when the main stirring blade 13 rotates to stir the powder at the bottom of the vessel 1, the bottom plate 14 will rotate continuously to push the powder at the bottom upward, so that the powder at the bottom can be replaced. This changes the contact object between the powder and the inner wall of the vessel 1, avoids the same part of the powder from continuously contacting the high-temperature inner wall, thereby reducing the overheating and sintering of the powder due to prolonged heating, and thus improving the reaction effect.

[0019] A second geared motor 4 is fixedly installed on the upper end of the lid 2. The upper end of the bushing 6 is fixed to the output end of the second geared motor 4.

[0020] The rotation control component includes a side plate shaft 26 fixedly installed at the other end of the side deflector 27. The side plate shaft 26 penetrates into the interior of the scraper 9 and serves to support the side deflector 27. The side plate shaft 26 and the scraper 9 are rotatably coupled. A side gear 34 is coaxially fixedly installed at the end of the side plate shaft 26. A toothed plate 21 is slidably installed inside the scraper 9. The side gear 34 meshes with the toothed plate 21. The engagement between the side gear 34 and the toothed plate 21 controls the rotation of the side deflector 27. The upper end of the toothed plate 21 extends into... Inside the casing 8, a bottom plate shaft 15 is fixedly installed at the upper end of the bottom plate 14. The bottom plate shaft 15 penetrates into the interior of the main stirring blade 13 and serves to support the bottom plate 14. The bottom plate shaft 15 is rotatably engaged with the main stirring blade 13. A bottom gear 25 is coaxially fixedly installed at the end of the bottom plate shaft 15. A horizontal toothed plate 22 is slidably installed inside the main stirring blade 13. The bottom gear 25 meshes with the horizontal toothed plate 22.

[0021] A pressure frame 24 is slidably installed inside the connecting shell 12. The pressure frame 24 extends through the upper end of the connecting shell 12. A push plate frame 23 is rotatably installed at the lower end of the pressure frame 24. The end of the push plate frame 23 is rotatably connected to the horizontal toothed plate 22. The vertical toothed plate 21, which slides up and down, will drive the pressure frame 24 to move synchronously. The moving pressure frame 24 pushes the push plate frame 23 to move, allowing the horizontal toothed plate 22 to slide back and forth. A synchronization ring 30 is fixedly installed at the upper end of the pressure frame 24. The synchronization ring 30 is located outside the stirring shaft 5 and is coaxial with the stirring shaft 5. A synchronization frame 10 is rotatably installed on the outer surface of the synchronization ring 30. The end of the synchronization frame 10 is fixed to the vertical toothed plate 21. The synchronization ring 30 and the synchronization frame 10 can connect the vertical toothed plate 21 and the pressure frame 24 together, so that the two can move synchronously and ensure that the rotation of the pressure frame 24 and the connecting shell 12 is not obstructed.

[0022] A shaft bracket 18 extends from the lower side of the bushing 6. A wheel axle 17 is rotatably mounted through the end of the shaft bracket 18, which supports the wheel axle 17. A control gear 16 is coaxially fixedly mounted on the upper end of the wheel axle 17. A gear ring 19 is coaxially fixedly mounted on the lower end of the vessel cover 2. The gear ring 19 allows the control gear 16 to rotate. The gear ring 19 is located outside the bushing 6, and the control gear 16 meshes with the gear ring 19. A push frame lug 32 is fixedly mounted on the lower end of the wheel axle 17. A reciprocating frame 31 is rotatably mounted on the end of the push frame lug 32. Ear 32 serves to drive the reciprocating frame 31 to move. A reciprocating frame 7 is rotatably mounted on the end of the reciprocating frame 31. A second push plate frame 28 is rotatably mounted on the side of the reciprocating frame 7. The end of the second push plate frame 28 is rotatably connected to one of the vertical toothed plates 21. The bushing 6 drives the control gear 16 to rotate in a circular motion. At this time, the control gear 16 will roll on the gear ring 19 to rotate, thereby driving the push frame ear 32 to rotate and push the reciprocating frame 31 to move, allowing the reciprocating frame 7 to slide back and forth, which in turn drives the second push plate frame 28 to move and push the vertical toothed plate 21 to slide back and forth.

[0023] A connecting plate 29 is rotatably mounted through the lower middle part of the cover 8. The stirring shaft 5 and the connecting shell 12 pass through the connecting plate 29, which serves as a connection. The stirring shaft 5, the connecting shell 12 and the connecting plate 29 are fixed together.

[0024] Two guide frames 33 extend symmetrically from the inner side of the cover 8. The reciprocating frame 7 is slidably mounted on the outer surface of the guide frame 33, and the guide frame 33 serves to guide the reciprocating frame 7.

[0025] The front and rear ends of the inner surface of the cover 8 are fixedly installed with a fixing bracket 20. The end of the fixing bracket 20 is fixed to the bushing 6. The fixing bracket 20 serves to fix the cover 8 and the bushing 6 together. The fixing bracket 20 is located below the gear ring 19.

[0026] During the reaction, the vessel body 1 heats the powder inside, while the stirring shaft 5 and the bushing 6 rotate in opposite directions, driving the main stirring blade 13, the auxiliary stirring blade 11, and the scraper 9 to rotate in opposite directions respectively, thus agitating the powder and increasing the contact between the powder particles for reaction. During this process, as the bushing 6 drives the scraper 9 to rotate, the control gear 16 is synchronously driven by the bushing 6 to rotate in a circular motion. At this time, the control gear 16 rolls on the gear ring 19, causing the push frame ear 32 to rotate and push the reciprocating frame 31 to move, allowing the reciprocating frame 7 to slide back and forth. This, in turn, drives the second push plate frame 28 to move and push the vertical toothed plate 21 to slide back and forth, allowing the side gear 34 to rotate. This, in turn, drives the side deflector 27 on the side plate shaft 26 to rotate, causing the scraper 9 to continuously rotate while agitating and scraping the powder on the inner wall of the vessel body 1. The side deflector 27 can move the powder on the inner wall toward the center of the vessel 1, so that the powder on the inner wall can be replaced. During the above process, the vertical toothed plate 21, which slides up and down, will also drive the pressure frame 24 to move synchronously. The moving pressure frame 24 pushes the first push plate frame 23 to move, so that the horizontal toothed plate 22 can slide left and right, so that the bottom gear 25 can rotate, thereby driving the bottom deflector 14 on the bottom plate shaft 15 to rotate. When the main stirring blade 13 rotates to stir the powder at the bottom of the vessel 1, the continuously rotating bottom deflector 14 can move the powder at the bottom upward, so that the powder at the bottom can be replaced. This changes the contact object between the powder and the inner wall of the vessel 1, avoids the same part of the powder from continuously contacting the high-temperature inner wall, thereby reducing the overheating and sintering of the powder due to prolonged heating, and thus improving the reaction effect.
