10. The method of using an autoclave for processing fiber-reinforced calcium silicate boards according to claim 8, characterized in that, Includes the following steps: S1: When using this autoclave, first open the steam valve (8) and supply steam into the autoclave to preheat it. After preheating, control the sealing cover (3) to open upwards. During the process, a large amount of steam will drift outwards and rise. When the sealing cover (3) is open, the crank rod (501) drives the gear one (502) to rotate around the connection between the sealing cover (3) and the autoclave body (1). When rotating, the gear is driven to rotate, and through the pulley group one (503), it drives the mounting rod (504) to rotate. The mounting rod (504) rotates. 4) Drive the pulley group two (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 impeller one (510) rotate. During the process, the impeller one (510) rotates rapidly to collect the scattered steam and transport it to the hose (508) through the rotating frame (509), the connecting piece (511) and the through hole (301). It is continuously transported into the interior of the condenser (6) and condensed water is generated in the condenser (6) and sent to the collection box. S2: When the sealing cover (3) is opened, one end of the pulley group three (701) is connected to the sealing cover (3), so that the pulley group three (701) is turned and the gear two (702) on the other side rotates synchronously, so that the collecting cover (704) slides towards the front of the vessel body (1). When the sealing cover (3) is opened, the collecting cover (704) is pushed forward to block the steam drifting from both sides of the vessel body (1) and make the steam rise upward and be collected by the rotating impeller one (510), further improving the steam collection effect. S3: After the sealing cover (3) is opened, the operator sends the pusher (10) containing the calcium silicate plate into the interior of the vessel body (1) and controls the sealing cover (3) to close. The steam valve (8) delivers steam to the two sets of steam pipes (901). When the steam is ejected from the steam nozzle, it contacts the impeller (905) and drives the impeller (905) and the thin plate roller (906) to rotate. The steam rises rapidly and is swung out of the steam guide tube (903) by the thin plate on the thin plate roller (906). A part of the steam is output from the front steam outlet (907) and another part of the steam is output from the side steam outlet (908). The steam output from the front steam outlet (907) mainly contacts the two sets of calcium silicate plates, and the steam output from the side steam outlet (908) mainly contacts the side of a single set of calcium silicate plates to improve the uniformity of steam distribution. When the thin plate roller (906) rotates, the lever... (909) Move the rotating plate (910) to tilt the rotating plate (910). The side of the rotating plate (910) that contacts the lever (909) is close to the inner wall of the vessel body (1), while the other side is relatively far away. This makes the steam output from the side steam outlet (908) closer to the side of the calcium silicate plate, accelerates the steam flow rate, enhances the heat exchange effect, and makes the side of the calcium silicate plate heat up quickly. When the rotating plate (910) rotates, the pusher (912) moves forward and pushes the pusher block (915) towards the pusher block (916). When the top of the pusher block moves, it pushes the pusher block (916) towards the support plate (913), so that the top rod (917) touches the support plate (913) and makes the rotating plate (911) tilt synchronously with the rotating plate (910) to keep the steam flowing forward quickly and further improve the steam pressure effect.
