[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 8 This utility model provides a technical solution: a rapid sealing device for an autoclave of autoclaved aerated concrete blocks, comprising an autoclave body 1, a fixed box 2, a rotating frame 3, and a sealing mechanism 16. The fixed box 2 is fixedly disposed at the front end of the autoclave body 1. A second fixed plate 5 and a first fixed plate 4 are symmetrically fixedly disposed at the top and bottom ends of the fixed box 2, respectively. The rotating frame 3 is movably mounted on the top of the fixed box 2 via the second fixed plate 5 and a rotating shaft 11. An autoclave cover 13 is fixedly disposed on the rear side of the bottom end of the rotating frame 3 via a connecting rod 12. The outer sides of both ends of the autoclave cover 13 are symmetrically provided with slots 14. The sealing mechanism 16 includes an adjusting frame 9, a sealing frame 18, and a bidirectional screw 6. The bidirectional screw 6 is rotatably and limit-controlled inside the first fixed plate 4 and the second fixed plate 5. The two ends of the adjusting frame 9 are symmetrically fixed with screw tubes 7. The middle position of the adjusting frame 9 is fixedly connected to the convex wall of the sealing frame 18 with a push rod 17. The sealing frame 18 is slidably and limit-controlled inside the two ends of the fixed box 2. The rear end of the second fixed plate 5 is provided with a transmission mechanism 10. Through the transmission mechanism 10, the sealing frame 18 can be moved and adjusted in the opposite direction, and the rotating frame 3 and the lid 13 can be rotated and adjusted in the opposite direction. This makes it easy to open the lid 13 and separate it from the body 1 without the need for staff to approach the lid 13, which can improve the safety and practicality of the sealing device.

[0026] In this embodiment, the front end of the vessel body 1 is provided with an installation port, and a sealing ring 15 is fixedly provided on the inner wall of the installation port. The vessel cover 13 is installed inside the installation port. Through the cooperation of the sealing ring 15 and the vessel body 1, the sealing performance between the vessel cover 13 and the vessel body 1 is easily improved.

[0027] In this embodiment, the rotating shaft 11 is rotatably mounted between the top ends of the second fixed plate 5. The rotating shaft 11 is fixedly mounted inside the middle section of the rotating frame 3. The rotating frame 3 is located on the outer side of the top end of the second fixed plate 5. A screw hole is provided at the top end of the rotating frame 3. A counterweight can be installed at the top end of the rotating frame 3 through the screw hole to facilitate the balance of the weight of the lid 13. This facilitates the subsequent rotation adjustment of the rotating frame 3 and the lid 13 through the transmission mechanism 10, and facilitates the opening and closing operation of the lid 13.

[0028] In this embodiment, the transmission mechanism 10 includes a rotating rod 22, a first sector gear 21, and a second sector gear 23. The rotating rod 22 is rotatably mounted inside the rear ends of the first fixed plate 4 and the second fixed plate 5. The first sector gear 21 is fixedly mounted on the outer side of one end of the rotating shaft 11, and the second sector gear 23 is fixedly mounted on the outer side of one end of the rotating rod 22. A second gear 8 is fixedly mounted on the outer side of the middle section of the bidirectional screw 6 between the first fixed plate 4 and the second fixed plate 5. The second gear 8 and the second sector gear 23 are meshed with each other. One side of the second sector gear 23 corresponds to the top rotating rod. A first gear 24 is fixedly installed on the rotating rod 22. The first gear 24 and the first sector gear 21 are arc-shaped meshed and arranged in parallel. A servo motor is provided at one end of the rotating rod 22. The servo motor can drive the rotating rod 22, the first gear 24 and the second sector gear 23 to rotate. It is convenient to rotate and adjust the rotating frame 3 and the lid 13 through the meshing action of the first gear 24 and the first sector gear 21. The second sector gear 23 rotates and adjusts the bidirectional screw 6 through the second gear 8. It is convenient to adjust the lid 13 and the sealing frame 18 in sequence. The operation is simple and does not require the staff to approach, which can improve the practicality of the sealing device.

[0029] In this embodiment, the two ends of the bidirectional screw 6 are screwed into the inside of the screw tube 7, the push rod 17 is inserted into the inside of the two ends of the fixed box 2, the sealing frame 18 is arc-shaped, and a protrusion 20 is fixedly provided at the middle position of the concave wall of the sealing frame 18 corresponding to the position of the slot 14. A sealing gasket 19 is fixedly provided on the inner wall of the sealing frame 18 and the outer wall of the protrusion 20. The protrusion 20 is inserted into the inside of the slot 14. The front end of the fixed box 2 corresponds to the mounting hole, and the connecting rod 12 is set inside the through hole. Through the screwing action of the bidirectional screw 6 and the screw tube 7, the adjusting frames 9 on both sides can be moved synchronously at the same time. The adjusting frame 9 drives the sealing frame 18 to move laterally inside the fixed box 2 through the push rod 17, which facilitates the merging and separation of the sealing frame 18 and the fixing of the lid 13 through the sealing frame 18. The protrusion 20 can be interlocked with the slot 14 to improve the stability of the lid 13.

[0030] When using the rapid sealing device for autoclaved aerated concrete block autoclaves, a counterweight is fixedly installed on the upper end of the rotating frame 3 using screws and screw holes. The counterweight balances the weight of the autoclave lid 13. The servo motor is fixedly installed on the top rear side of the fixed box 2 via a metal mounting plate. Servo controllers are installed on the top and bottom servo motors, and relevant parameters are set to control the synchronous operation of the two servo motors. The servo motors drive the rotating rods 22 at the top and bottom to rotate, and the rotating rods 22 at the top and bottom rotate synchronously. At the same time, the rotating rod 22 at the top drives the second sector gear 23 and the first gear 24 at the top to rotate, and the rotating rod 22 at the bottom drives the second sector gear 23 at the bottom to rotate. At this time, the second sector gear 23 and the second... The gears 8 are meshed together, while the first sector gear 21 and the first gear 24 are separated. The second sector gear 23 can drive the bidirectional screw 6 to rotate between the first fixed plate 4 and the second fixed plate 5 via the second gear 8. Through the screw connection between the bidirectional screw 6 and the screw tube 7, the adjusting frames 9 on both sides can be driven away from the fixed box 2. The adjusting frames 9 drive the sealing frame 18 to move to both sides inside the fixed box 2 via the push rod 17, causing the sealing frame 18 to separate from the lid 13. As the sealing frame 18 moves in the opposite direction, when the second sector gear 23 separates from the second gear 8, the first sector gear 21 and the first gear 24 mesh together, and through the first sector gear 21 and the first gear 8... The meshing action of gear 24 drives the rotating shaft 11 and the rotating frame 3 to rotate. The rotating frame 3 drives the vessel lid 13 to rotate upward and separate from the installation port, making it easy to open the vessel lid 13. The vessel lid 13 can be opened automatically without the need for personnel to approach it, which improves the safety and practicality of the sealing device. When processing autoclaved aerated concrete blocks, they are moved into the interior of the vessel body 1, and the first gear 24 and the second sector gear 23 are rotated by the servo motor and the rotating rod 22. At this time, the first sector gear 21 is meshed with the first gear 24, while the second sector gear 23 is separated from the second gear 8. The meshing action of the first gear 24 and the first sector gear 21 can drive the rotating shaft 11. The rotating frame 3 and the vessel lid 13 rotate to facilitate the sealing of the installation port through the vessel lid 13 and the sealing ring 15. After the vessel lid 13 is closed, the first sector gear 21 separates from the first gear 24, and the second sector gear 23 meshes with the second gear 8. The meshing action of the second gear 8 and the second sector gear 23 can drive the bidirectional screw 6 to rotate. Through the bidirectional screw 6, the screw tube 7, the adjusting frame 9, and the push rod 17, the sealing frame 18 is moved inside the fixed box 2, which facilitates the fixing of the vessel lid 13 through the cooperation of the sealing frame 18 and the sealing gasket 19, thereby improving the sealing performance between the vessel lid 13 and the vessel body 1. At the same time, the protrusion 20 is inserted into the slot 14 to facilitate the improvement of the stability between the vessel lid 13 and the sealing frame 18.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
