Description

Technical Field

[0001] The invention relates to the technical field of roller granulators, in particular to a double roller granulator. Background Art

[0002] As the global demand for renewable energy continues to increase, biomass energy, as one of the important renewable energy sources, has a broad market prospect; biomass fuel pellet machine, as an important equipment in the biomass energy industry chain, will continue to grow in market demand. Especially in the context of increasingly stringent environmental protection policies, biomass fuel pellet machine will play a more important role. Biomass liquid fuel pellet machine is a mechanical equipment that converts solid biomass energy into liquid or granular fuel, mainly used to produce various specifications of biomass granular fuel.

[0003] For example, the patent application number disclosed on the China Patent Network is: 202220843351.9, and the patent name is: A roller adjustment mechanism for a double-roller granulator, comprising a ring die and two rollers, both of which are connected to a support assembly, both of which include a bracket, and the bracket is rotatably connected to a support shaft for mounting the rollers through a bearing, and the rollers are passed through the ring die. The roller pressure adjustment mechanism includes a hydraulic cylinder arranged between the two brackets, and piston rods are connected on both sides of the hydraulic cylinder. The outer ends of the two piston rods are respectively connected to the two brackets, and the hydraulic cylinder is connected to the hydraulic station through a reversing valve and an accumulator. The roller adjustment mechanism of the double-roller granulator adjusts the gap distance between the roller and the ring die through a hydraulic cylinder, and has high adjustment accuracy and efficiency, which can extend the service life of the roller, and has a small amount of modification and low modification cost.

[0004] However, the structure of the double-roller pelletizer is relatively simple, and the hopper is located directly above. Users need to lift and dump the biomass raw material packages. For heavier or large packages of biomass raw materials, the operation is time-consuming and labor-intensive, which increases labor intensity. Frequent lifting and dumping of biomass raw materials may cause user fatigue and reduce work efficiency.

[0005] Secondly, when a large amount of biomass raw materials are directly dumped, the biomass raw materials are easy to accumulate inside the hopper and form pressure. The friction between the biomass raw materials will cause relative stillness, hindering the smooth falling of the biomass raw materials and causing the hopper to be blocked. After the blockage, the user needs to manually clear it, which increases the complexity of the operation and affects the production efficiency.

[0006] Finally, since the biomass raw materials need to be repeatedly lifted, dumped and cleared, the loading process takes a long time, reducing the overall production efficiency. The blockage problem may lead to production interruption, further affecting the continuity of equipment operation. In addition, the loading process lacks automation or auxiliary equipment. Users need to operate manually throughout the process, which is not convenient to operate. For biomass raw materials with poor fluidity, the blockage problem is more serious, which increases the difficulty of operation.

[0050] As a technical optimization solution of the present invention, the electric telescopic rod 17 drives the gear 16 to rotate through the tooth plate 19, and the sliding connection between the slide rod 15 and the sleeve plate 14 is combined to achieve the precise swing angle of the loading frame 11. The separate design of the gear 16 and the transmission rod 12 facilitates maintenance and independent control of power transmission, thereby reducing the scope of fault impact.

[0051] refer to Figure 6 The dredging component 8 includes a connecting frame 20 arranged on the top of the hopper 3, and a reciprocating screw 21 is movably connected to the interior of the connecting frame 20 through a bearing. A screw sleeve 22 is threadedly connected to the surface of the reciprocating screw 21, and a dredging rod 23 is installed at the bottom of the screw sleeve 22. The dredging rod 23 is elastic, and the dredging rod 23 extends to the inside of the hopper 3 away from the side of the screw sleeve 22. In the process of the reciprocating screw 21 pushing the screw sleeve 22 to move, the dredging rod 23 can be used to push the biomass raw materials accumulated inside the hopper 3. The adjustment structure 7 is arranged on the back of the hopper 3 and can drive the connecting frame 20 to flip and change the angle.

[0052] As a technical optimization solution of the present invention, the reciprocating screw 21 drives the screw sleeve 22 to drive the elastic dredging rod 23 to move left and right, and the biomass raw material lumps are dispersed by flexible pushing to avoid the wear of the equipment by hard dredging. The adjustment structure 7 allows the dredging component 8 to adjust the angle to adapt to biomass raw materials with different viscosities, improve the versatility, and prevent the dredging component 8 from affecting the filling of the biomass raw materials.

[0053] refer to Figure 6 The adjustment structure 7 includes columns 24 fixedly connected to both sides of the back side of the hopper 3, and the inner side of the columns 24 is movably connected to a support rod 25 through a bearing, and both sides of the surface of the support rod 25 are fixedly connected to a load-bearing rod 26, and the load-bearing rod 26 extends from the side of the support rod 25 to the top of the connecting frame 20 and is fixedly connected to the connecting frame 20. A linkage structure 27 is provided on one side of the loading frame 11. The linkage structure 27 can control the load-bearing rod 26 to drive the dredging component 8 to swing when the loading frame 11 is flipped over to load, so as to avoid the dredging component 8 from blocking the filling of biomass raw materials.

[0054] As a technical optimization solution of the present invention, through the bearing connection design of the load-bearing rod 26 and the support rod 25, the dredging component 8 can automatically swing and avoid with the linkage structure 27 during the loading process to avoid conflict with the biomass raw material flow. The compact layout of the column 24 and the support rod 25 reduces the equipment footprint while ensuring the adjustment range.

[0055] refer to Figure 6 The linkage structure 27 includes a fork 28 fixedly connected to the left end of the support rod 25. An extension rod 29 is fixedly connected to the back of the left bracket 10. The extension rod 29 extends from the side of the bracket 10 to the side of the fork 28. The side of the extension rod 29 away from the bracket 10 is fixedly connected to a push rod 30 located inside the fork 28. The push rod 30 and the fork 28 are slidably connected. When the bracket 10 swings, the extension rod 29 can use the extension rod 29 to pull the push rod 30 to squeeze the fork 28, so that the fork 28 uses the support rod 25 to drive the bearing rod 26 to swing synchronously.

[0056] As a technical optimization solution of the present invention, when the bracket 10 swings, the extension rod 29 and the push rod 30 drive the fork 28, which drives the dredging component 8 to move synchronously. No additional sensors or controllers are required, which reduces the complexity of the system. The sliding connection between the push rod 30 and the fork 28 ensures that the action is transmitted instantly to avoid the accumulation of biomass raw materials due to delays.

[0057] refer to Figure 5A frame 31 is fixedly connected to the back of the frame 1, and a pawl 32 is movably connected to the front of the frame 31 through a bearing. The rear end of the reciprocating screw 21 passes through the back of the connecting frame 20 and is fixedly connected to a ratchet 33. The ratchet 33 is located at the top of the ratchet 32. A driving assembly 34 is provided on the back of the frame 31. The driving assembly 34 can utilize the power of the transmission assembly 4 and drive the ratchet 32 ​​to rotate continuously.

[0058] As a technical optimization solution of the present invention, the power of the transmission assembly 4 is transmitted to the reciprocating screw 21 through the frame 31 and the ratchet 33-pawl 32 mechanism, so as to realize the synchronization of the dredging action and the operation of the main machine, which is energy-saving and efficient. The pawl 32 limits the unidirectional rotation of the ratchet 33, ensuring that the dredging rod 23 only moves in the set direction, thereby preventing the mechanism from being stuck due to the recoil of biomass raw materials.

[0059] refer to Figure 5 The driving assembly 34 includes a pulley 35 fixedly connected to the back of the pawl 32 and the transmission assembly 4 respectively. A belt 36 is sleeved on the surface of the pulley 35. During the continuous rotation of the transmission assembly 4, the pulley 35 and the belt 36 can be used to transmit power and drive the pawl 32 to rotate continuously.

[0060] As a technical optimization solution of the present invention, long-distance power transmission is achieved through the combination of pulley 35 and belt 36, which has a simple structure and low maintenance cost. The belt 36 transmission can buffer power fluctuations, reduce the impact on the dredging component 8, and extend the life of the equipment.

[0061] refer to Figure 7 The bottom of the screw sleeve 22 is fixedly connected with a guide plate 37 , and the dredging rod 23 is inserted into the inside of the guide plate 37 and can slide left and right inside the guide plate 37 .

[0062] As a technical optimization solution of the present invention, the moving trajectory of the dredging rod 23 is constrained by the guide plate 37 to prevent uneven dredging or component wear caused by deflection. The sliding design reduces the vibration of the dredging rod 23 to ensure smooth and continuous pushing action.

[0063] refer to Figure 7 The interior of the connecting frame 20 is fixedly connected to a corrugated plate 38 located at the bottom of the screw sleeve 22. The surface of the corrugated plate 38 is provided with a corrugated groove. The top end of the dredging rod 23 extends into the groove of the corrugated plate 38 and is slidably connected to the corrugated plate 38.

[0064] As a technical optimization solution of the present invention, the grooves of the corrugated plate 38 are used to make the top of the dredging rod 23 swing periodically to generate slight vibrations, thereby further breaking up the agglomerates of biomass raw materials and increasing the contact area between the dredging rod 23 and the biomass raw materials.

[0065] The working principle and use process of the present invention are as follows: when the equipment is started, the transmission component 4 such as the motor and the transmission wheel continuously drives the pressing roller in the granulating body 2 to rotate synchronously, and enters the granulating state. The user puts the biomass raw material into the loading frame 11 set at a low position, and drives the tooth plate 19 to move horizontally through the electric telescopic rod 17 constituting the transmission structure 6. During the movement, the gear 16 uses the mutually meshing teeth to push the gear 16 to rotate. The gear 16 drives the shaft 9 to rotate, driving the bracket 10 and the loading frame 11 to flip upward with the shaft 9 as the axis, and the biomass raw material is lifted to the hopper. 3 and dumped. This process does not require manual lifting of biomass raw materials, reducing labor intensity. After the biomass raw materials enter the hopper 3, the dredging component 8 is started. The core of the dredging component 8 is that the reciprocating screw 21 drives the screw sleeve 22 and the elastic dredging rod 23 to move back and forth in the hopper 3 by rotating, pushing and dispersing the accumulated biomass raw materials to prevent blockage caused by static friction. At the same time, the adjustment structure 7 such as the support rod 25 and the bearing rod 26 can adjust the angle of the connecting frame 20 so that the dredging rod 23 can adapt to different accumulation forms. When the loading frame 11 is turned over to load, the bracket 10 The extension rod 29 is used to drive the push rod 30 to slide inside the fork 28. The fork 28 is squeezed and the support rod 25 is used to drive the bearing rod 26 to flip upward. The push rod 30 pushes the fork 28 to drive the support rod 25 to swing, so that the dredging component 8 temporarily avoids when the biomass raw material is dumped to avoid hindering the loading of the material. After the dumping is completed, the dredging component 8 is reset to continue to dredge. When the dredging component 8 is reset, the ratchet 33 on one side of the dredging component 8 moves to the bottom of the pawl 32, and the pawl 32 is connected to the transmission component 4 through the driving component 34. When the motor and the transmission wheel of the transmission assembly 4 rotate continuously, the torque can be transmitted to the pawl 32 through the pulley 35 and the belt 36. The pawl 32 intermittently pushes the ratchet wheel 33 to rotate during the continuous rotation, driving the reciprocating screw 21 to rotate continuously, ensuring the continuity of the dredging action. The guide plate 37 and the corrugated plate 38 at the bottom of the screw sleeve 22 constrain the moving trajectory of the dredging rod 23 through sliding cooperation, so that the dredging rod 23 can swing back and forth laterally, thereby enhancing the pushing efficiency and expanding the contact area with the biomass raw materials inside the hopper 3, further improving the dredging effect.

[0066] In summary: the double-roller granulator is supported by a frame 1, a granulator body 2 is installed on the top of the frame 1, a hopper 3 is connected to the top of the granulator body 2, a transmission assembly 4 is located on the back of the frame 1, and drives the rollers inside the granulator body 2 to rotate, and a feeding structure 5, a transmission structure 6, an adjustment structure 7 and a dredging assembly 8 are respectively responsible for the feeding, flipping and opening and closing, angle adjustment and guiding of biomass raw materials, ensuring the smooth progress of the granulation process, so that the granulator can efficiently and continuously granulate the biomass raw materials.
