DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5As shown, an autoclave for producing autoclaved fly ash bricks comprises an autoclave body 1, a front support frame 2 and a rear support frame 3 are arranged at the bottom of the autoclave body 1, guide rods 10 are symmetrically penetrated through the front support frame 2, arc-shaped air suction shells 4 are arranged on both sides of the front end of the autoclave body 1, and the arc-shaped air suction shells 4 are connected to the guide rods 10, an air suction mechanism 6 for extracting air inside the arc-shaped air suction shell 4 is arranged on the top of the autoclave body 1, and a driving mechanism 11 for driving the arc-shaped air suction shell 4 to move forward and backward is arranged on the front support frame 2.

[0021] In this embodiment, when the front end of the autoclave body 1 is opened, the driving mechanism 11 controls the arc-shaped air suction shell 4 to move toward the front end of the autoclave body 1, and then the air inside the arc-shaped air suction shell 4 is sucked by the air suction mechanism 6, and a negative pressure is generated inside the arc-shaped air suction shell 4, so that the high-temperature air gushing out of the gap between the autoclave door and the autoclave body is sucked into the arc-shaped air suction shell 4, and finally the high-temperature air is discharged by the air suction mechanism 6 to the top of the autoclave body 1, thereby improving the safety of the autoclave used for the production of autoclaved fly ash bricks.

[0022] like Figure 4 As shown, the interior of the arc-shaped air suction shell 4 is a hollow structure, and a plurality of air suction holes are evenly arranged on the inner side of the arc-shaped air suction shell 4. A protective net 5 is arranged inside the air suction holes. When the air suction mechanism 6 sucks air, it draws the high-temperature gas gushing out between the kettle door and the kettle body through the air suction holes. The protective net 5 prevents large particles of impurities from entering the interior of the arc-shaped air suction shell 4.

[0023] like Figure 1 and Figure 2 As shown, the air suction mechanism 6 is an air suction shell arranged on the top of the autoclave body 1, and multiple air suction hoses 7 are penetrated on both sides of the air suction shell. The other end of the air suction hose 7 penetrates into the interior of the arc-shaped air suction shell 4. Multiple high-temperature resistant fans 8 are arranged inside the air suction shell, and an exhaust port is penetrated on the top of the air suction shell, and a filter screen 9 is arranged inside the exhaust port.

[0024] In this embodiment, by starting the high temperature resistant fan 8, the high temperature resistant fan 8 draws air from the arc-shaped suction shell 4 through the suction hose 7, and the air is finally discharged to the top of the autoclave body 1 through the exhaust port.

[0025] like Figure 5 As shown, the driving mechanism 11 includes a motor, a threaded rod 13 and a nut block 12. The motor is arranged on the front support frame 2, the threaded rod 13 is arranged at the output end of the motor, the nut block 12 is arranged on the arc-shaped air intake shell 4, and the threaded rod 13 is threadedly connected in the threaded hole of the nut block 12.

[0026] In this embodiment, the motor is a forward and reverse motor, and the threaded rod 13 is driven to rotate forward by making the output end of the motor rotate forward. When the threaded rod 13 rotates forward, the nut block 12 is driven away from the motor. The nut block 12 is driven away from the motor to drive the arc-shaped air intake shell 4 to move toward the front of the autoclave body 1, thereby achieving the purpose of controlling the movement of the arc-shaped air intake shell 4.

[0027] like Figure 3 As shown, a stopper 14 is provided at one end of the threaded rod 13 away from the motor, and the stopper 14 is used to limit the position of the nut block 12 .

[0028] like Figure 1 As shown, a door body 15 is hinged on the front of the autoclave body 1 , and the door body 15 is used to close the autoclave body 1 .

[0029] Working principle: when the front end of the autoclave body 1 is opened, the threaded rod 13 is driven to rotate forward by making the output end of the motor rotate forward. When the threaded rod 13 rotates forward, it drives the nut block 12 away from the motor. The nut block 12 moves away from the motor and drives the arc-shaped air suction shell 4 to move toward the front of the autoclave body 1, thereby achieving the purpose of controlling the arc-shaped air suction shell 4 to move toward the front end of the autoclave body 1. Then, the high-temperature resistant fan 8 is started, and the high-temperature resistant fan 8 draws the air inside the arc-shaped air suction shell 4 through the air suction hose 7. Negative pressure is generated inside the arc-shaped air suction shell 4, so that the high-temperature air gushing out of the gap between the autoclave door and the autoclave body is sucked into the arc-shaped air suction shell 4, and finally the high-temperature air is discharged by the air suction mechanism 6 to the top of the autoclave body 1, thereby improving the safety of the autoclave used for the production of autoclaved fly ash bricks.
