Description

Technical Field

[0001] The invention relates to the technical field of biomass, and in particular to a biomass fuel rod forming device. Background Art

[0002] Biomass fuel rods refer to biomass materials burned as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. At present, after the biomass is crushed and dried, a combustion rod forming device is used to squeeze the crushed biomass to compress it into a rod shape. The current fuel rod forming device does not have a structure for cutting the combustion rods when in use. When in use, after the combustion rods are pressurized by the device, they need to rely on their own weight and subsequent rods to break when extruded through the device. The combustion rods extruded by the device are of different lengths and uneven fractures. During subsequent packaging, debris is easy to fall off the fracture. In order to solve the above-mentioned problems, we propose a biomass fuel rod forming device. Summary of the invention

[0007] The above technical solution is used to transport and extrude biomass fuel through the setting of the forming assembly; After the specific biomass fuel is put into the silo, the driving motor drives the conveying auger to rotate and transport the fuel downward. After the fuel enters the extrusion bin, the extrusion motor starts to drive the extrusion screw to rotate. The extrusion screw rotates to transport and extrude the fuel. As the front end diameter of the extrusion bin decreases, the fuel is squeezed more densely, enters the extrusion bin to form a rod shape, and is finally discharged through the front end of the extrusion bin.

[0013] The above technical solution is adopted, through the setting of the linkage component 2, which is used to follow the rotation of the transmission component 2, thereby driving the linkage component 1 to rotate; When pulley three rotates and drives pulley four to rotate through the belt rotation, the connecting rod inside pulley four will rotate along with it because it is fixedly connected to the upper connecting bin. The rotation of the connecting rod drives the bevel gear three fixedly connected to its surface to rotate, and the bevel gear four meshing with it is driven by the bevel gear three to rotate, thereby driving the rotating rod to rotate through the bevel gear four.

[0015] The above technical solution is adopted, through the setting of the driving component, to drive the conveying auger to rotate to convey the fuel downward, and also to drive the transmission component 2, the linkage component 2 and the linkage component 1 to rotate and to allow the cutting component to cut off the combustion rods discharged from the silo; The driving motor controls the rotation speed of its output end through a controller, and the controller is used in combination with electricity as an existing technology; when the driving motor rotates, it drives the conveying auger to rotate, and the conveying auger will accelerate the fuel output end to the inside of the extrusion bin, but the extrusion screw rod inside the extrusion bin is driven to rotate by the extrusion motor, so the delivery and extrusion speed of the fuel inside the extrusion bin will not be affected by the delivery speed of the fuel by the delivery auger; By controlling the rotation speed of the output end of the driving motor by the controller, the driving motor accelerates the rotation speed of the conveying auger while also accelerating the rotating structures in the transmission component 2, the linkage component 2, the linkage component 1 and the cutting component; By accelerating the rotation speed of the connecting rod, rotating rod, rotating rod and reciprocating screw, the rotation speed of the reciprocating screw is increased and the threaded blocks on its surface will reciprocate at a faster speed; By controlling the rotation speed of the output end of the control drive motor to slow down, the rotation speed of the connecting rod, rotating rod, rotating rod and reciprocating screw will also slow down. When the reciprocating screw slows down, the reciprocating speed of the cutter driven by the threaded block connected to its surface will also slow down relatively. In summary, by accelerating the rotation speed of the reciprocating screw and slowing down the rotation speed of the reciprocating screw, the cutting work of combustion rods of different lengths can be met; by setting the controller, the specific rotation speed of the output end of the driving motor is adjusted to adjust the reciprocating cutting speed of the cutter on the combustion rod.

When the output end of the driving motor rotates, its output end will drive the conveying auger to rotate and also drive the pulley three on the surface of the conveying auger to rotate. The rotation of pulley three drives pulley four through the belt to drive the connecting rod inside it to rotate.

[0029] Working principle: First, the device is powered on, the length of the burning rod is cut as required, and the stable speed of the driving motor 64 is set by the controller; The biomass fuel is put into the silo 1, and the driving motor 64 is started to drive the conveying auger 61 to rotate through the coupling, and the conveying auger 61 stirs the fuel and conveys it downward.

[0030] When the conveying auger 61 rotates, the conveying auger 61 will drive the pulley three 72 on its surface to rotate, the rotation of the pulley three 72 drives the connecting rod 51 inside it to rotate through the belt transmission upper connecting bin 71, the rotation of the connecting rod 51 drives the bevel gear three 52 to rotate, the rotation of the bevel gear three 52 drives the bevel gear four 53 meshing with it to rotate, the rotation of the bevel gear four 53 drives the rotating rod 42 inside it to rotate, and the rotating rod 42 drives the bevel gear one 43 on its surface to rotate.

The conveying auger 61 conveys the fuel downward into the extrusion bin 21. After the fuel enters the extrusion bin 21, the extrusion motor 23 starts to drive the extrusion screw rod 22 to convey the fuel. As the inner diameter of the extrusion bin 21 decreases in the conveying direction of the extrusion screw rod 22, the fuel will be continuously squeezed, compressed and conveyed, and finally enters the front end of the extrusion bin 21, where it will be formed into a rod shape and will be continuously discharged through the silo 1 as the fuel is conveyed.

[0032] When the fuel is discharged, the reciprocating cutter 333 will cut the combustion rod once when moving forward, and cut the combustion rod again when resetting. The stable reciprocating speed of the synchronous cutter 333 can ensure that the length of the combustion rod is consistent each time, thereby achieving fixed-distance cutting of the combustion rod.
