The limiting groove 24 is engaged with to realize the sliding restriction of the plate body 2, so that the plate body 2 can still adjust the inclination angle during use, thereby improving the flue gas diversion effect, and when the plate body 2 is removed from the mounting plate 1 for cleaning or replacement, the inclined groove 51 pushes the limiting rod 3 to slide through the sliding of the pressing block 5, so that the limiting rod 3 and the limiting groove 24 are disengaged, and the plate body 2 can be removed from the mounting plate 1, thereby improving the portability when cleaning or replacing the plate body 2. When the mounting plate 1 is installed on the reactor body 7 or removed from the reactor body 7, the rotation of the plate body 2 is restricted by the limiting component to prevent the plate body 2 from rotating during the process, causing inconvenience in operation, and the attachments on the plate body 2 from falling into the inside of the reactor body 7.

[0023] Specifically, a first spring 31 is provided between the limit rod 3 and the mounting plate 1, and the two ends of the first spring 31 are fixedly connected to the limit rod 3 and the mounting plate 1 respectively. An inclined surface 25 is provided on the second rotating shaft 23 and contacts the limit rod 3 through the inclined surface 25. When the plate body 2 is installed on the mounting plate 1, the second rotating shaft 23 is inserted into the mounting plate 1, and the inclined surface 25 on the second rotating shaft 23 contacts the limit rod 3, and pushes the limit rod 3 to slide and stretch the first spring 31, so that the inclined surface 25 of the second rotating shaft 23 passes the position of the limit rod 3, and under the reset action of the first spring 31, the limit rod 3 is engaged with the limit groove 24, and, when the first spring 31 is not During stretching, the limit rod 3 is engaged with the limit groove 24, and the pressure block 5 is in a normal state. When the plate body 2 is removed from the mounting plate 1, the pressure block 5 slides, and the limit rod 3 slides and disengages from the limit groove 24 through the squeezing action of the inclined groove 51 and the limit rod 3, and the first spring 31 is stretched. A plurality of gaskets 12 are fixedly provided on the mounting plate 1. When the mounting plate 1 in the plate body 2 is removed, the mounting plate 1 can be turned upside down on the ground, and pressure is applied to the mounting plate 1 to make the pressure block 5 slide, and the disengagement of the limit rod 3 from the limit groove 24 is completed. The gasket 12 is used to prevent the pressure block 5 from sliding excessively and to ensure the stability of the mounting plate 1 when it is turned upside down.

[0024] In an embodiment further provided by the present invention, the limiting assembly includes a lifting frame 4 slidably arranged on the mounting plate 1, a sliding block 41 is slidably arranged on the lifting frame 4, a cross block 43 is fixedly arranged on the sliding block 41, a cross slot 26 is provided on the second rotating shaft 23, and the cross block 43 is plugged into the cross slot 26. When the mounting plate 1 is installed on or removed from the reactor body 7, the lifting frame 4 is at the bottom. At this time, the cross block 43 is plugged into the cross slot 26 to limit the rotation of the plate body 2. The limit rod 3 limits the sliding of the plate body 2 to stabilize the plate body 2 and prevent the plate body 2 from rotating due to external force during the process, causing the attached objects of the plate body 2 to fall into the reactor body 7. When the mounting plate 1 is installed and removed, the operation is more portable and labor-saving. After the mounting plate 1 is installed, the lifting frame 4 moves up and drives the cross block 43 to slide and disengage from the cross slot 26. The contact controls the rotation of the plate body 2 so that the plate body 2 can adjust its tilt angle during use.

[0025] Furthermore, a second spring 42 is provided between the sliding block 41 and the lifting frame 4. Both ends of the second spring 42 are fixedly connected to the sliding block 41 and the lifting frame 4, respectively. When the mounting plate 1 is removed from the reactor body 7, the lifting frame 4 moves downward, causing the cross block 43 to reset and engage with the cross slot 26, thereby ensuring the stability of the plate body 2 during the removal of the mounting plate 1. If the tilt angle of the plate body 2 is not reset when the lifting frame 4 moves downward, the cross block 43 cannot engage with the cross slot 26, and the second spring 42 is compressed to adjust the tilt angle of the plate body 2. After adjustment, the cross block 43 engages with the cross slot 26 under the action of the second spring 42, thereby preventing the mounting plate 1 from colliding with the reactor body 7 due to the tilt angle not being reset when the mounting plate 1 is removed, thereby hindering the removal of the mounting plate 1.

[0026] Furthermore, it also includes a locking assembly, which locks the pressure block 5 through the locking assembly during the rising process of the lifting frame 4; the locking assembly includes an abutment rod 44 fixedly arranged on the lifting frame 4, and a vertical groove 52 is provided on the pressure block 5, and the abutment rod 44 is slidably set in the vertical groove 52. After the mounting plate 1 is installed, when the plate body 2 is in use, the lifting frame 4 moves up to make the abutment rod 44 abut against the top of the vertical groove 52. At this time, the pressure block 5 is locked to prevent the pressure block 5 from sliding due to external force, resulting in unstable engagement between the limit rod 3 and the limit groove 24, thereby improving the stability of the plate body 2 during use.

[0027] In an embodiment further provided by the present invention, a sliding rod 6 is slidingly provided on the mounting plate 1, and a connecting rod 61 is provided between the sliding rod 6 and the lifting frame 4, and the two ends of the connecting rod 61 are rotatably connected to the sliding rod 6 and the lifting frame 4 respectively; a screw rod 13 is rotatably provided on the mounting plate 1, and the screw 13 is threadedly connected to the sliding rod 6. The sliding rod 6 is caused to slide by the rotation of the screw rod 13, and the lifting and lowering of the lifting frame 4 is controlled by the connecting rod 61, which is used to adjust the restriction and contact of the rotation of the plate body 2, as well as the locking and unlocking of the limit rod 3.

[0028] In the embodiment provided by the present invention, a fixed shell 72 is fixedly provided on the reactor body 7, and a plurality of pulleys 73 are rotatably provided on the fixed shell 72. The two pulleys 73 in the middle are fixedly connected and are respectively connected to the pulleys 73 on both sides through belts 75; a plug-in slot 74 is provided on the pulley 73, a first rotating shaft 21 is fixedly provided on the plate body 2, a plug-in portion 22 is provided on the first rotating shaft 21, and the plug-in portion 22 is slidably plugged into the plug-in slot 74, a motor 76 is fixedly provided on the fixed shell 72, and the output shaft of the motor 76 is connected to the One of the pulleys 73 is fixedly connected, and the two pulleys 73 located in the middle position are fixedly connected, and are rotatably connected to the pulleys 73 on both sides through belts 75. When the motor 76 drives one of the pulleys 73 to rotate, the belt 75 can be used to transmit the power so that multiple pulleys 73 rotate at the same time. Moreover, when the mounting plate 1 is installed on the reactor body 7, the plug-in portion 22 on each plate body 2 is plugged into the plug-in groove 74 on the corresponding pulley 73, and the inclination angle of the plate body 2 can be adjusted by rotating the pulley 73.

[0029] Specifically, a guide tube 11 is fixedly provided on the mounting plate 1, and a guide rod 71 is fixedly provided on the reactor body 7. The guide tube 11 and the guide rod 71 are slidably plugged into each other. When the mounting plate 1 is installed on or removed from the reactor body 7, the guide tube 11 is plugged into the guide rod 71, so that the mounting plate 1 is more stable and more labor-saving during the process. At the same time, it is convenient to align the plug-in portion 22 on the first rotating shaft 21 with the plug-in groove 74.

[0030] Working principle: When installing the plate body 2, the second rotating shaft 23 of the plate body 2 is inserted into the mounting plate 1, the inclined surface 25 on the second rotating shaft 23 contacts the limiting rod 3, and pushes the limiting rod 3 to slide and stretch the first spring 31, so that the second rotating shaft 23 passes the position of the limiting rod 3, and under the reset action of the first spring 31, the limiting rod 3 is engaged with the limiting groove 24 to limit the sliding of the plate body 2. At the same time, the cross block 43 is plugged into the cross groove 26 to limit the rotation of the plate body 2. After installing each plate body 2 in turn, the guide tube 11 is plugged into the guide rod 71, and the plug-in portion 22 on each first rotating shaft 21 is plugged into the plug-in groove 74 on the corresponding pulley 73, and then the installation is fixed by bolts. The plate 1 is connected and fixed to the reactor body 7. After the fixation is completed, the screw 13 is rotated to make the sliding rod 6 slide and push the lifting frame 4 to rise through the connecting rod 61. The lifting frame 4 slides with the sliding block 41 and the cross block 43 through the second spring 42, so that the cross block 43 is disconnected from the cross groove 26, thereby releasing the restriction on the rotation of each plate body 2. At the same time, the abutment rod 44 abuts against the upper end of the vertical groove 52 to limit the sliding of the pressing block 5. Through the action between the inclined groove 51 on the pressing block 5 and the limit rod 3, the sliding of the limit rod 3 is locked, so that the card connection between the limit rod 3 and the limit groove 24 is more stable, thereby improving the stability of the plate body 2 during use.

[0031] During use, the pulley 73 is driven to rotate by the motor 76, and the multiple pulleys 73 are rotated simultaneously through the belt 75. Under the plug-in action of the plug-in portion 22 and the plug-in groove 74, the inclination angle of each plate body 2 is adjusted to improve the diversion effect of the plate body 2.

[0032] During the disassembly process, the screw 13 is rotated to make the sliding rod 6 slide and the lifting frame 4 move down. During the downward movement, the cross block 43 is plugged into the cross slot 26. If the plate body 2 is not reset at this time, the cross block 43 compresses the second spring 42, and then the plate body 2 is reset, so that the cross block 43 is plugged into the cross slot 26 under the action of the second spring 42, thereby limiting the rotation of the plate body 2 and ensuring the stability of the plate body 2 during the disassembly process. Subsequently, the mounting plate 1 is removed from the reactor body 7. When replacing the plate body 2, the mounting plate 1 is turned upside down on the ground and pressure is applied to make the pressing block 5 slide. The inclined groove 51 on the pressing block 5 squeezes the limit rod 3, the first spring 31 is stretched, the limit rod 3 is disengaged from the limit slot 24, and the sliding restriction of the plate body 2 is released. Then the plate body 2 can be removed from the mounting plate 1 for cleaning and replacement.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
