Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment:

[0024] Please refer to Figs. 1-3 The present application provides a technical solution: a vertical drying system for fiberboard production, comprising a dust removal device 1, the dust removal device 1 is connected with a heating device 2 through a pipeline, the heating device 2 is connected with a first fan 3, the first fan 3 is connected with a first conveying pipe 4, the first conveying pipe 4 is provided with a feed inlet 5 for feeding, the end of the first conveying pipe 4 is connected with a first cyclone separator 6, the exhaust end of the first cyclone separator 6 is connected with a second cyclone separator 8 through a second conveying pipe 7, the end of the second conveying pipe 7 away from the second cyclone separator 8 is provided with a second fan 9, the second fan 9 is in communication with the heating device 2, and the second cyclone separator 8 is in communication with the dust removal device 1;

[0025] The discharge outlets of the first cyclone separator 6 and the second cyclone separator 8 are respectively provided with oscillating devices 10, the oscillating device 10 comprises a support 11, the top of the support 11 is provided with a mounting seat, the mounting seat is slidably connected with a sliding rod 12, one end of the sliding rod 12 close to the side wall of the discharge outlet is provided with a protruding block 13, the other end of the sliding rod 12 away from the protruding block 13 is provided with a push block 14, the outer wall of the sliding rod 12 is provided with a spring 15, one end of the spring 15 abuts against the mounting seat, the other end of the spring 15 abuts against the push block 14, the support 11 is connected with a driving device 16 for sliding the sliding rod 12.

[0026] Specifically, the driving device 16 comprises a gear ring 30 rotatably connected to the support 11, the inner side wall of the gear ring 30 is provided with an arc segment 31, the diameter of the arc segment 31 is smaller than the inner diameter of the gear ring 30, the outer wall of the gear ring 30 is meshingly connected with a gear 32, the top of the support 11 is connected with a mounting frame 18, the top of the mounting frame 18 is provided with a motor 17, the output end of the motor 17 is connected with the gear 32. The motor 17 drives the gear 32 to rotate, and the gear 32 drives the gear ring 30 to rotate. During the rotation of the gear ring 30, the arc segment 31 sequentially contacts different push blocks 14, so that the sliding rod 12 slides to the side close to the side wall of the discharge outlet, the protruding block 13 collides with the side wall of the discharge outlet, causing the vibration of the side wall of the discharge outlet, thereby shaking off the wood fibers blocked in the discharge outlet.

[0027] Specifically, the side of the protruding block 13 close to the side wall of the discharge outlet is provided with a rubber block 19. The setting of the rubber block 19 prevents the direct collision between the protruding block and the side wall of the discharge outlet during the sliding of the sliding rod, thereby preventing the damage of the side wall of the discharge outlet.

[0028] Specifically, the end of the first conveying pipe 4 close to the inlet 5 is provided with a crushing fan blade 20. The airflow blown by the first fan 3 flows in the first conveying pipe 4, and the airflow flow drives the crushing fan blade 20 to rotate. The rotating crushing fan blade 20 disperses the caked wood fibers, avoids the caking of the wood fibers with high water content, and thereby reduces the drying efficiency.

[0029] Specifically, the dust removal device 1 comprises two bag dust collectors 21, the bag dust collectors 21 are respectively connected with first control valves 22, and the first control valves 22 are connected with the heating device 2. The passages of the air outlets of the corresponding bag dust collectors 21 are respectively controlled to be opened or closed through the first control valves 22. When one of the bag dust collectors 21 needs to be maintained and cleaned, the first control valve 22 connected with the bag dust collector 21 is closed, and the other first control valve 22 is opened, and the air from the bag dust collector 21 connected with the first control valve 22 enters the heating device 2.

[0030] The two bag dust collectors 21 are switched to use, thereby preventing the drying system from being temporarily stopped due to the need for the bag dust collector 21 to be cleaned.

[0031] Specifically, the exhaust end of the second cyclone separator 8 is connected with a backflow fan 23, and the second cyclone separator 8 is communicated with the dust removal device 1 through the backflow fan 23.

[0032] Specifically, the heating device 2 is connected with a high-temperature adjusting valve 24 for adjusting the air intake amount of the first fan 3 and the second fan 9.

[0033] Specifically, the outer walls of the first conveying pipe 4 and the second conveying pipe 7 are wrapped with heat preservation sleeves. The heat loss of the hot air in the conveying process in the first conveying pipe 4 and the second conveying pipe 7 is reduced through the heat preservation sleeves.

[0034] Specifically, the first conveying pipe 4 is composed of a first vertical pipe 26, a second vertical pipe 27, a horizontal pipe 28 and a third vertical pipe 29. The first vertical pipe 26 is connected with the first fan 3, and the feeding port 5 is arranged on the outer wall of the first vertical pipe 26. The third vertical pipe 29 is connected with the first cyclone separator 6.

[0035] One specific application of the embodiment is that the first fan 3 and the second fan 9 suck the air outside into the corresponding first conveying pipe 4 and second conveying pipe 7. After the air is sucked into the bag-type dust collector 21, the dust in the air is adsorbed by the bag-type dust collector 21. The purified air is heated by the heating device 2 and then blown to the first conveying pipe 4 and the second conveying pipe 7.

[0036] After being heated and ground, the wood fibers enter the first conveying pipe 4 through the feeding port 5, and the wood fibers move to the first cyclone separator 6 under the driving of the hot air. The air blown by the first fan 3 flows in the first conveying pipe 4, and the flow of the air flow drives the crushing fan blade 20 to rotate. The wood fibers encounter the rotating crushing fan blade 20 in the moving process, and the wood fibers are dispersed by the rotating crushing fan blade 20, so as to avoid the agglomeration of the wood fibers with high water content, thereby reducing the drying efficiency.

[0037] The hot air carrying the wood fibers enters the inner cavity of the first cyclone separator 6 from the tangential direction of the first cyclone separator 6. In the inner cavity of the first cyclone separator 6, the wood fibers are separated from the hot air for the first time, and the wood fibers slide along the inner cavity of the first cyclone separator 6 to the discharge port. The separated wood fibers are moved to the next process by the conveyor. The hot air carrying part of the unseparated wood fibers is discharged from the exhaust port at the top of the first cyclone separator 6 and enters the second conveying pipe 7. At the same time, the second fan 9 blows the hot air into the second conveying pipe 7 to make up for the heat loss of the hot air in the first conveying pipe 4. The hot air carrying part of the unseparated wood fibers enters the inner cavity of the second cyclone separator 8 from the tangential direction of the second cyclone separator 8. In the inner cavity of the second cyclone separator 8, the wood fibers are separated from the hot air for the second time, and the wood fibers slide along the inner cavity of the second cyclone separator 8 to the discharge port.

[0038] When the separated wood fibers block the discharge port of the first and second cyclone separators 6 and 8, the motor 17 drives the gear 32 to rotate, and the gear 32 drives the gear ring 30 to rotate. During the rotation of the gear ring 30, the arc-shaped section 31 contacts the different push blocks 14 in turn, so that the slide rod 12 slides to the side close to the discharge port side wall, and the protruding block 13 collides with the discharge port side wall, causing the vibration of the discharge port side wall, thereby shaking off the wood fibers blocked in the discharge port. After the arc-shaped section 31 is separated from the push block 14, the slide rod 12 is reset under the pushing of the spring 15.
