[0030] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figures 1 to 5As shown, a novel multi-layer biomass dryer includes a drying cylinder 1. A feed pipe 2 is installed on one side of the upper end of the drying cylinder 1 for feeding biomass pellets. A discharge pipe 3 is installed on the other side of the lower end of the drying cylinder 1. The dried biomass pellets flow out through the discharge pipe 3. A valve can be installed on the discharge pipe 3. A receiving frame or conveyor belt can be placed below the discharge pipe 3 for convenient transportation.

[0033] A support plate 29 is installed on the upper end of the base plate 4. Side plates 30 are installed on both sides of the upper end of the support plate 29. Connecting blocks 31 are hinged inside the two side plates 30. The connecting blocks 31 can rotate inside the side plates 30. A heater 6 is installed on the upper end of the connecting blocks 31. An air inlet 7 is installed on one end of the heater 6. The air inlet 7 is connected to an external pipe. One end of the heater 6 is connected to the drying cylinder 1. The heater 6 heats the incoming air and passes it into the drying cylinder 1 to dry the biomass pellets. An air outlet pipe 33 is installed on the upper end of the drying cylinder 1 to facilitate the outflow of gas.

[0034] The adjustment structure 8 is located on both sides of the upper end of the base plate 4 and is connected to the drying cylinder 1. The adjustment structure 8 includes a second motor 24. A screw 25 is installed at the output end of the second motor 24. One end of the screw 25 is rotatably connected to one end of a support plate. The support plate is installed on the upper end of the base plate 4 and is used to support the screw 25. A moving block 26 is threaded onto the surface of the screw 25. A mounting block 28 is fixedly installed on one side of the drying cylinder 1. A connecting rod 27 is hinged to one end of the mounting block 28, and the other end of the connecting rod 27 is hinged to the upper end of the moving block 26.

[0035] When motor 24 starts, it can drive screw 25 to rotate, thereby causing moving block 26 to move along the direction of screw 25. The two ends of support rod 27 rotate at mounting block 28 and moving block 26 respectively. One end of support rod 27 drives one end of drying cylinder 1 to move upward through mounting block 28, so that drying cylinder 1 tilts, which facilitates the flow of biomass pellet material.

[0036] Rotary drum 9 is located inside drying drum 1, and rotary drum 10 is located inside rotary drum 9. Transmission structure 11 is located inside drying drum 1 at one end away from heater 6 and is connected to rotary drum 9 and rotary drum 10.

[0037] The transmission structure 11 includes a protective shell 12. A motor 13 is installed at one end of the protective shell 12. The motor 13 is located outside the drying drum 1. A rotatable shaft 14 is installed inside the protective shell 12. One end of the shaft 14 is connected to the output end of the motor 13. The other end of the shaft 14 is rotatably installed outside the heater 6. The motor 13 can drive the shaft 14 to rotate. A cross bracket 19 is installed on the surface of the shaft 14 near the heater 6. The cross bracket 19 is fixedly connected to one end of the rotating drum 9. The rotation of the shaft 14 can drive the rotating drum 9 to rotate through the cross bracket 19.

[0038] A bevel gear 15 is fixedly fitted on the surface of the rotating shaft 14. A rotatable bevel gear 16 is installed inside the protective shell 12. The bevel gear 16 meshes with the bevel gear 15. The rotating shaft 18 is rotatably fitted on the surface of the rotating shaft 14. A bevel gear 17 is installed at one end of the rotating shaft 18 that passes through the protective shell 12. The bevel gear 17 meshes with the bevel gear 16. A cross bracket 20 is installed at one end of the rotating shaft 18. The cross bracket 20 is fixedly installed inside the rotating cylinder 10.

[0039] When the rotating shaft 14 rotates, it drives the bevel gear 15 to rotate, which in turn drives the meshing bevel gear 2 16 to rotate, which in turn drives the meshing bevel gear 3 17 to rotate, thereby driving the rotating shaft 2 18 to rotate. Through the cross support 2 20, the rotating drum 2 10 is driven to rotate. When the rotating drum 2 10 rotates, it causes small particles to flow out and enter the interior of the rotating drum 1 9, which can separate large particles from small particles and prevent small particles of biomass material from being blocked, thus affecting the drying efficiency.

[0040] It should be noted that a bushing 21 is rotatably fitted on the surface of the rotating shaft 18 near the cross bracket 19. A cross bracket 22 is installed on the surface of the bushing 21. The cross bracket 22 is fixedly installed inside the rotating drum 10 and serves to support the rotating drum 19. A turntable 23 is fixedly fitted on the outer surface of one end of the rotating drum 19. The turntable 23 rotates inside the drying drum 1 as it is currently in operation. The turntable 23 serves to support the rotating drum 19. Multiple sets of circumferentially arrayed lifting plates 32 are installed on the inner walls of the rotating drum 19 and the rotating drum 20. During the flow of biomass materials, the rotation of the rotating drum 19 and the rotating drum 20 drives the lifting plates 32 to rotate. The lifting plates 32 can lift the biomass particles and then let them fall, thus accelerating the drying speed.

[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure.
