[0002] Fiber-reinforced calcium silicate board is a new type of lightweight board made of siliceous material and calcium material as the main body, with cellulose fiber, alkali-resistant glass fiber and other reinforcing fibers as the reinforcement, through molding, steam or high-pressure steam curing and other processes;

[0003] In the prior art, when using an autoclave to process fiber reinforced calcium silicate board, it is necessary to preheat the autoclave in advance, because in the production of fiber reinforced calcium silicate board, the main cementitious material will undergo hydration reaction in a high temperature and high pressure autoclave environment. Preheating the autoclave in advance can make the board blank be in a temperature environment more suitable for reaction when entering the autoclave stage, so that the hydration reaction can proceed more evenly and fully, thereby enhancing the internal structure of the board and improving the strength and durability of the board. After the autoclave is preheated and then opened, a large amount of steam will drift outward, which will cause waste of steam and make it inconvenient to collect it. Therefore, we propose an autoclave for processing fiber reinforced calcium silicate board and a method of use to solve the above problems. Summary of the invention

[0011] Preferably, a rotating rod is arranged at the center of the steam nozzle, and the rotating rod is rotatably connected to the steam delivery pipe. The top of the rotating rod is fixedly connected to a second impeller, and the top of the second impeller is fixedly connected to a thin plate drum.

[0012] Preferably, a front steam outlet is opened on the front side of the steam guide cylinder, and a side steam outlet is opened at one end of the side of the steam guide cylinder. The front steam outlet is used to conduct steam between adjacent two groups of calcium silicate boards, and the side steam outlet is used to conduct steam to the side of the calcium silicate board.

A first rotating plate and a second rotating plate are respectively movably installed between two adjacent steam guide cylinders. A resisting head is fixedly provided on the top of the first rotating plate near one side of the second rotating plate, and a supporting plate is fixedly provided on the top of the second rotating plate near one side of the resisting head.

[0014] Preferably, the bottoms of the first rotating plate and the second rotating plate are both rotatably connected to the steam conveying pipe, and the connection parts are both far away from the centers of the bottoms of the first rotating plate and the second rotating plate. The dial rod abuts against the first rotating plate, and its function is to drive the first rotating plate to swing when rotating.

[0015] Preferably, tension springs are fixedly connected to the sides of the first rotating plate and the second rotating plate close to the inner wall of the autoclave.

[0016] Preferably, it further includes a pushing frame. Calcium silicate boards are equidistantly arranged on the pushing frame, and the steam guide cylinder is close to the space between two adjacent calcium silicate boards.

[0017] Preferably, a using method of an autoclave for processing fiber-reinforced calcium silicate boards includes the following steps:

[0018] S1: When the autoclave is in use, first open the steam valve and convey steam into the autoclave to preheat the autoclave. After the preheating is completed, control the sealing cover to open upward. During this process, a large amount of steam drifts outwards and rises. When the sealing cover is opened, the curved rod drives the first gear to rotate around the connection part between the sealing cover and the autoclave. When rotating, the gear is driven to rotate. The installation rod is driven to rotate through the first pulley group. The installation rod drives the second pulley group to rotate, so that the worm drives the worm wheel to rotate. Through the worm wheel, the connecting piece, the rotating frame and the first impeller rotate. During this process, the first impeller rotates rapidly to collect the steam that drifts out, and conveys it into the hose through the rotating frame, the connecting piece and the through hole, and continuously conveys it into the condenser, and condensed water is generated through the condenser and collected in the collecting box;

[0019] S2: At the same time when the sealing cover is opened, one end of the third pulley group is connected to the sealing cover, so that the third pulley group operates, and the second gear on the other side rotates synchronously, so that the gathering cover slides forward towards the front side of the autoclave. At the same time when the sealing cover is opened, the gathering cover is pushed forward to block the steam that drifts out from both sides of the autoclave and make the steam rise upwards, and is collected by the rotating first impeller, further improving the steam collection effect;

[0020] S3: After the sealing cover is opened, the operator sends the push rack with the calcium silicate board into the interior of the kettle body, and controls the sealing cover to close. The steam valve sends steam to the two groups of steam pipes. When the steam is ejected from the steam nozzle, it contacts the second impeller, and drives the second impeller and the thin plate roller to rotate. The steam rises rapidly and is sent out of the steam guide tube by the thin plate swing on the thin plate roller. Part of the steam is output from the front steam outlet, and the other part of the steam is output from the side steam outlet. The steam output from the front steam outlet mainly contacts between the two groups of calcium silicate boards, and the steam output from the side steam outlet mainly contacts the side of a single group of calcium silicate boards to improve the uniformity of steam distribution. When rotating, the lever moves the rotating plate 1 to tilt the rotating plate 1. The side of the rotating plate 1 that contacts the lever is close to the inner wall of the kettle body, while the other side is relatively far away, so that the steam output from the side steam outlet is closer to the side of the calcium silicate board, accelerating the circulation speed of the steam, enhancing the heat exchange effect, and quickly heating the side of the calcium silicate board. When the rotating plate 1 rotates, the head moves forward to push the push block 1 in the direction of the push block 2. The top of the push block 1 pushes the push block 2 in the direction of the support plate when moving, so that the top rod touches the support plate, and the rotating plate 2 and the rotating plate 1 are tilted synchronously to keep the steam flowing forward quickly, and further improve the autoclaving effect.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, through the steam collecting mechanism, when the sealing cover is opened, a large amount of steam floats outward and rises, and the installation rod is driven to rotate by the pulley set, so that the worm drives the worm wheel to rotate. During the process, the impeller rotates rapidly to collect the floating steam, and transports it into the hose, and continuously transports it to the inside of the condenser, and generates condensed water through the condenser to the collection box. During the process of opening the kettle, the steam is collected, which can save energy consumption and reduce the emission of greenhouse gases, thereby achieving the effect of energy saving and environmental protection;

[0023] 2. In the present invention, by means of the gathering mechanism, when the sealing cover is opened, the gathering cover is pushed forward to block the steam drifting out from both sides of the kettle body, and make the steam rise upward to be collected by the rotating impeller, thereby further improving the steam collection effect and preventing the steam from drifting to both sides of the kettle body to prevent scalding of the operator;

[0024] 3. In the present invention, a part of the steam is output from the front steam outlet and the other part of the steam is output from the side steam outlet by means of the steam diffusion mechanism, so that steam flows in the gap between the two groups of calcium silicate boards, and steam also continuously flows on the side surface of the calcium silicate board close to the side of the kettle body, which can improve the uniformity of steam distribution, accelerate the heat exchange effect of steam, and improve the steam-compression efficiency.

A steam guide cylinder 903 is fixedly connected to the top of the plurality of steam nozzles 902;

[0050] A front steam outlet 907 is opened on the front side of the steam guide cylinder 903, and a side steam outlet 908 is opened at one end of the side surface of the steam guide cylinder 903. The front steam outlet 907 is used for conducting steam between two adjacent groups of calcium silicate boards, and the side steam outlet 908 is used for conducting steam to the side surface of the calcium silicate board;

[0051] A lever 909 is fixedly connected to the top of the thin plate drum 906.

[0057] The usage method and advantages of the present invention: The autoclave for processing fiber-reinforced calcium silicate boards and its usage method are as follows:

[0058] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 shown:

[0059] S1: When the autoclave is in use, first open the steam valve 8 and send steam into the interior of the autoclave to preheat the autoclave. After the preheating is completed, control the sealing cover 3 to open upward. During this process, a large amount of steam drifts outward and rises. At this time, when the sealing cover 3 is opened, the curved rod 501 drives the first gear 502 to rotate around the connection point between the sealing cover 3 and the kettle body 1 as the axis. When rotating, the gear is driven to rotate. The installation rod 504 is driven to rotate through the first pulley group 503. The installation rod 504 drives the second pulley group 505 to rotate, so that the worm 506 drives the worm wheel 507 to rotate. Through the worm wheel 507, the connecting piece 511, the rotating frame 509 and the first impeller 510 rotate. During this process, the first impeller 510 rotates rapidly to collect the dispersed steam, and conveys it into the hose 508 through the rotating frame 509, the connecting piece 511 and the through hole 301, and continuously conveys it into the interior of the condenser 6, and condensed water is generated through the condenser 6 and sent to the collection box;

[0060] S2: While the sealing cover 3 is opened, one end of the third pulley group 701 is connected to the sealing cover 3, so that the third pulley group 701 operates, and the second gear 702 on the other side rotates synchronously, so that the gathering hood 704 slides forward to the front side of the kettle body 1. While the sealing cover 3 is opened, the gathering hood 704 is pushed forward to block the steam dispersed from both sides of the kettle body 1 and make the steam rise upward, and is collected by the rotating first impeller 510, further improving the steam collection effect;

[0061] S3: After the sealing cover 3 is opened, the operator sends the push rack 10 with the calcium silicate board into the interior of the kettle body 1, and controls the sealing cover 3 to close. The steam valve 8 sends steam to the two groups of steam pipes 901. When the steam is ejected from the steam nozzle, it contacts the second impeller 905, and drives the second impeller 905 and the thin plate roller 906 to rotate. The steam rises rapidly and is sent out of the steam guide tube 903 by the thin plate swing on the thin plate roller 906. Part of the steam is output from the front steam outlet 907, and the other part of the steam is output from the side steam outlet 908. The steam output from the front steam outlet 907 mainly contacts between the two groups of calcium silicate boards, and the steam output from the side steam outlet 908 mainly contacts the side of a single group of calcium silicate boards to improve the uniformity of steam distribution. When the thin plate roller 906 rotates, the dial The rod 909 moves the rotating plate 910 to tilt the rotating plate 910. The side of the rotating plate 910 that contacts the shifting rod 909 is close to the inner wall of the kettle body 1, and the other side is relatively far away, so that the steam output from the side steam outlet 908 is closer to the side of the calcium silicate board, accelerating the circulation speed of the steam, enhancing the heat exchange effect, and quickly heating the side of the calcium silicate board. When the rotating plate 910 rotates, the head 912 moves forward to push the push block 915 in the direction of the push block 2 916. The top of the push block 1 pushes the push block 2 916 in the direction of the support plate 913 when moving, so that the top rod 917 touches the support plate 913, so that the rotating plate 2 911 and the rotating plate 910 are tilted synchronously to keep the steam flowing forward quickly and further improve the autoclaving effect.

10. The usage method of an autoclave for processing fiber-reinforced calcium silicate boards according to claim 1, characterized in that, It includes the following steps: S1: When the autoclave is in use, first open the steam valve (8), and convey steam into the autoclave to preheat the autoclave. After the preheating is completed, control the sealing cover (3) to open upward. During this process, a large amount of steam drifts outwards and rises. When the sealing cover (3) is opened, the curved rod (501) drives the first gear (502) to rotate around the connection between the sealing cover (3) and the autoclave body (1) as the axis. When rotating, the gear is driven to rotate. The installation rod (504) is driven to rotate through the first pulley group (503). The installation rod (504) drives the second pulley group (505) to rotate, so that the worm (506) drives the worm wheel (507) to rotate. Through the worm wheel (507), the connecting piece (511), the rotating frame (509) and the first impeller (510) rotate. During this process, the first impeller (510) rotates rapidly to collect the drifted steam, and conveys it into the hose (508) through the rotating frame (509), the connecting piece (511) and the through hole (301), and continuously conveys it into the condenser (6), and condensed water is generated through the condenser (6) and collected into the collection box; S2: While the sealing cover (3) is opened, one end of the third pulley group (701) is connected to the sealing cover (3), so that the third pulley group (701) operates. The second gear (702) on the other side rotates synchronously, so that the gathering hood (704) slides forward to the front side of the autoclave body (1). While the sealing cover (3) is opened, the gathering hood (704) is pushed forward to block the steam drifting out from both sides of the autoclave body (1), and make the steam rise upward and be collected by the rotating first impeller (510), further improving the steam collection effect; S3: After the sealing cover (3) is opened, the operator puts the push rack (10) on which the calcium silicate boards are placed into the interior of the kettle body (1), and controls the sealing cover (3) to close. The steam valve (8) delivers steam to the two groups of steam pipes (901). When the steam is ejected from the steam jet, it contacts the second impeller (905), and drives the second impeller (905) and the thin plate roller (906) to rotate. The steam rises rapidly and is sent out of the steam guide tube (903) by the thin plate swing on the thin plate roller (906). A part of the steam is output from the front steam outlet (907), and the other part of the steam is output from the side steam outlet (908). The steam output from the front steam outlet (907) mainly contacts between the two groups of calcium silicate boards, and the steam output from the side steam outlet (908) mainly contacts the side of a single group of calcium silicate boards, so as to improve the uniformity of steam distribution. When the thin plate roller (906) rotates, the lever (909) moves the rotating plate 1 (910) to tilt the rotating plate 1 (910). The side of the rotating plate 1 (910) in contact with the shifting rod (909) is close to the inner wall of the kettle body (1), while the other side is relatively far away, so that the steam output from the side steam outlet (908) is closer to the side of the calcium silicate board, accelerating the circulation speed of the steam, enhancing the heat exchange effect, and causing the side of the calcium silicate board to heat up quickly. When the rotating plate 1 (910) rotates, the butt head (912) moves forward to push the push block 1 (915) in the direction close to the push block 2 (916). When the top of the push block 1 moves, it pushes the push block 2 (916) in the direction close to the support plate (913), so that the top rod (917) touches the support plate (913), so that the rotating plate 2 (911) and the rotating plate 1 (910) are tilted synchronously, so as to keep the steam flowing forward quickly and further improve the steam pressure effect.
