The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figures 1 to 4The embodiment of the present application provides a drying device for biomass fuel briquette, including a frame 1, a heating and drying device installed in the frame 1, a feed port 2 is provided on the top of the frame 1, a hinge shaft 3 is rotatably installed in the frame 1, a movable frame 4 is hinged on the hinge shaft 3, and one end of the movable frame 4 away from the hinge shaft 3 is installed on the frame 1 through a telescopic mechanism, a plurality of flipping plates 5 are rotatably installed on the movable frame 4, and the plurality of flipping plates 5 are spaced and staggered. The movable frame 4 is slidably connected to a driving frame 6, and a telescopic rod 7 is installed on the driving frame 6. The telescopic rod 7 can be a multi-stage telescopic rod, and the output end of the telescopic rod 7 is hinged to the flipping plate 5. A linear drive device 8 is installed on the movable frame 4, and the linear drive device 8 can be an electric push rod, which and the rotation drive device 12 should be connected to the signal of the signal processor, and the output end of the linear drive device 8 is connected to the driving frame 6; A conveyor 9 is installed in the frame 1. The conveyor 9 can be a belt conveyor or a chain conveyor in the prior art. Several push plates 10 are installed on the conveyor 9. A crank shaft 11 is rotatably installed in the frame 1. The crank shaft 11 is arranged in conjunction with the mobile frame 4. A rotation drive device 12 is installed on the frame 1. The rotation drive device 12 can be a servo motor or a stepper motor. The output end of the rotation drive device 12 is connected to the conveyor 9 in transmission. The output end of the rotation drive device 12 is connected to the crank shaft 11 through a belt drive assembly. The belt drive assembly is a prior art and will not be described in detail. It can also be changed to a chain drive assembly according to demand, and different specifications of drive wheels can be installed according to the input end of the conveyor 9 and the input end of the crank shaft 11 to achieve the purpose of vibrating the mobile frame 4 several times and the conveyor 9 drives the push plate 10 to move a certain distance.

[0021] When drying, the material enters from the feeding port 2 on the frame 1 and is output from the output end of the mobile frame 4. During drying, the rotary drive device 12 drives the conveyor 9 to rotate. At the same time, the rotary drive device 12 drives the crank shaft 11 to rotate through the belt transmission assembly, so that the mobile frame 4 hinged on the hinge shaft 3 in the frame 1 can produce a certain up and down vibration effect around the hinge shaft 3 under the push of the crank shaft 11, and the telescopic mechanism on the mobile frame 4 cooperates with it to vibrate, so that the material accumulated on the mobile frame 4 can gradually move to the output end of the mobile frame 4 due to the up and down swing of the mobile frame 4 itself. At this time, the conveyor 9 drives several push plates 10 thereon to push the material on the mobile frame 4 so that the material can be flattened; while the push plate 10 pushes the material, the linear drive device 8 drives the driving frame 6 to move, thereby driving several flipping plates 5 to rotate on the mobile frame 4, and the material on the mobile frame 4 can be flipped to the other side. The material layer that pushes 10 is rolled upside down again, and this material layer ...

[0022] In some embodiments, to facilitate the up-and-down vibration of the mobile frame 4, a telescopic mechanism is provided, including a base 13, a slider 14, and a spring 15. The base 13 is hingedly connected to the frame 1, the slider 14 slides and engages within the base 13, and the spring 15 is mounted within the base 13. The output end of the spring 15 is connected to the slider 14, which is hingedly connected to the mobile frame 4. When the mobile frame 4 vibrates, the slider 14 can slide up and down in the base 13. After the vibration is completed, the mobile frame 4 can return to its original position due to the changes in the spring 15 and the gravity of the mobile frame 4.

[0023] In some embodiments, in order to avoid collision between the telescopic rod 7 and the flipping plate 5 when the telescopic rod 7 drives the flipping plate 5 to flip, a rounded corner is provided at the hinge between the telescopic rod 7 and the flipping plate 5.

[0024] In some embodiments, in order to facilitate pushing the materials accumulated at the center of the mobile rack 4 to both sides, the push plate 10 is set to be V-shaped and is mounted on the conveyor 9 through the bottom mounting block. The setting of the bottom mounting block of the push plate 10 does not affect the rotation of the conveyor 9.

[0025] In some embodiments, to prevent the material from getting stuck in the groove of the turning plate 5, a stopper 16 is installed on the movable frame 4, and the stopper 16 is arranged in conjunction with the turning plate 5. At this time, the turning angle of the turning plate 5 is a maximum of 90 degrees, which can still flip the material.

[0026] In some embodiments, to insulate the interior of the frame 1, a sealing curtain 17 is installed within the frame 1, and the sealing curtain 17 abuts against the movable frame 4. The sealing curtain 17 is placed on the movable frame 4. Its long length allows the sealing curtain 17 to always maintain a sealed state when the movable frame 4 vibrates. The sealing curtain 17 seals the space between the upper surface of the movable frame 4 and the frame 1. Both sides of the movable frame 4 abut against the frame 1, so that only the discharge end of the movable frame 4 is susceptible to hot air loss. The sealing curtain 17 can also be installed to maintain a certain sealing and heat preservation effect.
