[0002] In the global energy structure, thermal power generation has long occupied an important position. With the continuous development of the economy, the demand for electricity continues to grow. The main principle of thermal power generation is to generate heat energy by burning fuel, heat water into steam, drive the turbine to rotate, and then drive the generator to generate electricity. Traditional thermal power generation mainly uses coal as fuel, but in recent years, in the face of the demand for diversified energy and environmental pressure, the comprehensive utilization of multiple fuels has gradually become a trend.

[0003] Existing multi-fuel supply devices for thermal power generation mostly use coal, biomass fuels, etc. as combustibles when in use. However, if coal and biomass fuels are not crushed and dried before use, incomplete combustion will occur.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the intelligent multi-fuel supply device based on thermal power generation equipment, the coal is transported to the top of the first feed hopper through a conveyor belt, and then falls from the first feed hopper to the coal crushing box, and then falls between the two crushing rollers under the guidance of the first guide plate. The first servo motor drives the first rotating rod to rotate, which can drive the first gear to rotate, and then drive the second gear meshing with the first gear to rotate, and at the same time drive the second rotating rod to rotate. When the first rotating rod and the second rotating rod rotate at the same time, the two crushing rollers will be driven to rotate, and the two crushing rollers rotate in opposite directions, and then the coal can be crushed by multiple crushing teeth. This design can efficiently crush the coal to make its particle size smaller, and then solve the problem that the supply equipment is stuck due to large coal particles in the subsequent coal supply process, so that the subsequent coal supply and transportation process is smoother.

[0018] 2. The intelligent multi-fuel supply device based on thermal power generation equipment, when the first servo motor drives the first rotating rod to rotate, it will drive the third gear to rotate, and when the third gear rotates, it will drive the fourth gear to rotate under the action of the transmission belt, thereby driving the third rotating rod to rotate, and when the third rotating rod rotates, it will drive the worm to rotate, and at the same time, it can drive the worm wheel meshing with the worm to rotate, thereby driving the fourth rotating rod to rotate, and when the fourth rotating rod rotates, it can drive the coal grinding device to work. Compared with two independent servo motors driving separately, this design can ensure that the power output of the crushing and grinding devices has better coordination, and solves the problem of coal accumulation or insufficient feed supply caused by speed mismatch.

[0019] 3. In the intelligent multi-fuel supply device based on thermal power generation equipment, after the coal blocks are crushed, they enter the coal grinding box through the feeding channel. When the first servo motor is started to drive the first rotating rod to rotate, the worm gear and the fourth rotating rod can be driven to rotate. When the fourth rotating rod rotates, it will drive the second guide plate and the first rotating cylinder to rotate, and then drive multiple grinding rollers to rotate. After the coal blocks pass through the feeding channel and fall into the coal grinding box, they will fall onto the surface of the second guide plate. When the second guide plate rotates, the centrifugal force will drive the fallen coal blocks to move to the edge until they fall through the gap between the second guide plate and the inner wall of the coal grinding box. When falling, the grinding rollers will rotate and cooperate with the inner wall of the coal grinding box to grind the fallen coal blocks, so that the coal blocks can be ground into coarse coal powder, which further improves the smoothness of subsequent coal fuel supply. At the same time, when the fuel is supplied to the combustion equipment for combustion, the ground coarse coal powder is more convenient for it to be fully burned than coal, and at the same time solves the problem that the incomplete combustion of coal causes waste of resources and is not conducive to environmental protection.

[0020] 4. In the intelligent multi-fuel supply device based on thermal power generation equipment, the biomass fuel is transported to the top of the second feed hopper through a conveyor belt, and then discharged from the second feed hopper into the biomass fuel processing box. The second servo motor drives the second rotating cylinder to rotate, driving the multiple crushing teeth to rotate, so as to crush the biomass fuel. At the same time, the hot air blower is started to blow hot air into the second rotating cylinder through the air intake pipe. The hot air is ejected from the multiple openings on the surface of the second rotating cylinder, so as to evenly dry the biomass fuel while crushing it. The physical properties of the crushed and dried biomass fuel are more uniform, which solves the problem of unstable combustion due to uneven internal water content and particle size when the uncrushed and dried biomass fuel is directly supplied to the combustion equipment for combustion.

[0021] 5. The intelligent multi-fuel supply device based on thermal power generation equipment can efficiently supply the processed coal and biomass fuel to the combustion equipment for combustion and power generation by driving the screw rod to rotate through the third servo motor. When in use, the solenoid valve is opened, and the processed coarse coal powder or biomass fuel will fall into the supply pipe through the discharge pipe, and then the third servo motor drives the screw rod to rotate to drive the coarse coal powder or biomass fuel to be stably transported and supplied to the combustion equipment, thereby ensuring the continuity and stability of fuel combustion in the combustion equipment, thereby improving the continuity and stability of power generation, and can effectively reduce energy loss and improve the energy conversion efficiency of the entire power generation system.

[0034] The coal is transported to the top of the first feed hopper 5 by the conveyor belt and then falls from the first feed hopper 5 to the coal crushing box 4. Then, it falls between the two crushing rollers 13 under the guidance of the first guide plate 6. The first servo motor 8 drives the first rotating rod 9 to rotate, which can drive the first gear 10 to rotate, and then drive the second gear 11 meshing with the first gear 10 to rotate, and at the same time drive the second rotating rod 12 to rotate. When the first rotating rod 9 and the second rotating rod 12 rotate at the same time, the two crushing rollers 13 will be driven to rotate, and the two crushing rollers 13 rotate in opposite directions, and then the coal can be crushed by multiple crushing teeth 14. This design can efficiently crush the coal to make its particle size smaller, and then solve the problem that the supply equipment is stuck due to large coal particles in the subsequent coal supply process, so that the subsequent coal supply and transportation process is smoother.

[0035] Embodiment 2, as Figure 1 , Figure 2 , Figure 4 As shown, an intelligent multi-fuel supply device based on thermal power generation equipment is provided, a coal grinding box 16 is arranged below the coal crushing box 4, a third gear 17 is welded on the rear end of the first rotating rod 9 penetrating the coal crushing box 4, a transmission toothed belt 18 is meshed on the outer surface of the third gear 17, a fourth gear 19 is meshed on the inner surface of the other end of the transmission toothed belt 18, a third rotating rod 20 is welded on the inner surface of the fourth gear 19, a first bearing seat 21 is welded on the upper end of the coal grinding box 16, the third rotating rod 20 is rotatably connected to the first bearing seat 21, a worm 22 is welded on one end of the third rotating rod 20, a worm wheel 23 is meshed on one side of the worm 22, and a fourth rotating rod 24 is welded inside the worm wheel 23.

[0036] When the first servo motor 8 drives the first rotating rod 9 to rotate, it will drive the third gear 17 to rotate. When the third gear 17 rotates, it will drive the fourth gear 19 to rotate under the action of the transmission belt 18, and then drive the third rotating rod 20 to rotate. When the third rotating rod 20 rotates, it will drive the worm 22 to rotate, and at the same time, it can drive the worm wheel 23 meshing with the worm 22 to rotate, and then drive the fourth rotating rod 24 to rotate.

Compared with two independent servo motors driving separately, this design can ensure that the power output of the crushing and grinding devices has better coordination, and solves the problem of coal accumulation or insufficient feed supply caused by speed mismatch.

[0037] Embodiment three, as Figure 1-Figure 5 As shown, an intelligent multi-fuel supply device based on thermal power generation equipment, two feeding channels 15 are welded at the lower end of the coal crushing box 4, a second bearing seat 25 is also welded at the upper end of the coal grinding box 16, a fourth rotating rod 24 is rotatably connected to the second bearing seat 25, a second guide plate 26 is welded to the outer surface of the fourth rotating rod 24, a first rotating cylinder 27 is also welded to the outer surface of the fourth rotating rod 24, two groups of fixed seats 28 are evenly welded on the outer surface of the first rotating cylinder 27 in a ring shape, a movable rod 29 is movably connected between every two fixed seats 28, and a grinding roller 30 is welded to the outer surface of the movable rod 29.

[0038] After being crushed, the coal block enters the coal grinding box 16 through the material discharge channel 15. When the first servo motor 8 is started to drive the first rotating rod 9 to rotate, the worm gear 23 and the fourth rotating rod 24 can be driven to rotate. When the fourth rotating rod 24 rotates, it will drive the second guide plate 26 and the first rotating cylinder 27 to rotate, and then drive the plurality of grinding rollers 30 to rotate. After the coal block falls into the coal grinding box 16 through the material discharge channel 15, it will fall on the surface of the second guide plate 26. When the second guide plate 26 rotates, it will drive the falling rollers 30 under the action of centrifugal force. The coal blocks move toward the edge until they fall through the gap between the second guide plate 26 and the inner wall of the coal grinding box 16. When falling, the grinding roller 30 rotates and cooperates with the inner wall of the coal grinding box 16 to grind the falling coal blocks. The coal blocks can be ground into coarse coal powder, which further improves the smoothness of subsequent coal fuel supply. When the fuel is supplied to the combustion equipment 46 for combustion, the ground coarse coal powder is easier to fully burn than coal, and at the same time solves the problem of waste of resources caused by incomplete combustion of coal, which is not conducive to environmental protection.

[0039] Embodiment 4, as Figure 1 , Figure 6 , Figure 7 , Figure 8As shown, an intelligent multi-fuel supply device based on thermal power generation equipment, a biomass fuel processing box 31 is detachably connected to the middle part of the second support frame 3, a second feed hopper 32 is welded to one side of the biomass fuel processing box 31, a second servo motor 33 is detachably connected to the top of the biomass fuel processing box 31, the output end of the second servo motor 33 passes through the biomass fuel processing box 31 and is detachably connected to the second rotating cylinder 34 through a coupling, a plurality of groups of crushing teeth 35 are welded to the outer surface of the second rotating cylinder 34, two toggle plates 36 are also welded to the outer surface of the second rotating cylinder 34, a plurality of openings 37 are provided on the surface of the second rotating cylinder 34, a hot air blower 38 is detachably connected to the upper end of the bottom plate 1, an air intake pipe 39 is detachably connected to one side of the hot air blower 38, the other end of the air intake pipe 39 passes through the grinding roller 30 and is inserted into the second rotating cylinder 34, and the outer circle diameter of the air intake pipe 39 is slightly smaller than the inner circle diameter of the second rotating cylinder 34.

[0040] The biomass fuel is transported to the top of the second feed hopper 32 through a conveyor belt, and then discharged from the second feed hopper 32 into the biomass fuel processing box 31. The second servo motor 33 drives the second rotating cylinder 34 to rotate, driving the multiple crushing teeth 35 to rotate, so as to crush the biomass fuel. At the same time, the hot air blower 38 is started to blow hot air into the second rotating cylinder 34 through the air intake pipe 39. The hot air is ejected from the multiple openings 37 on the surface of the second rotating cylinder 34, so as to evenly dry the biomass fuel while crushing it. The physical properties of the crushed and dried biomass fuel are more uniform, which solves the problem of unstable combustion due to uneven internal water content and particle size when the uncrushed and dried biomass fuel is directly supplied to the combustion equipment 46 for combustion.

[0041] Embodiment 5, as Figure 1 , Figure 3 , Figure 6 , Fig. 9 As shown, an intelligent multi-fuel supply device based on thermal power generation equipment, a discharge pipe 40 is welded to the lower end of the biomass fuel processing box 31 and the coal grinding box 16, a solenoid valve 41 is detachably connected to the middle of the discharge pipe 40, a supply pipe 42 is welded to the lower end of the discharge pipe 40, two support blocks 43 are arranged at the lower end of the supply pipe 42, a third servo motor 44 is detachably connected to the surface of one side of the supply pipe 42, the output end of the third servo motor 44 passes through the supply pipe 42 and is detachably connected to a screw rod 45 through a coupling, a combustion device 46 is detachably connected between the two supply pipes 42, and a power generation device 47 is installed on the upper end of the combustion device 46.

[0042] By setting the third servo motor 44 to drive the screw rod 45 to rotate, the processed coal and biomass fuel can be efficiently supplied to the combustion equipment 46 for combustion and power generation. When in use, the solenoid valve 41 is opened. At this time, the processed coarse coal powder or biomass fuel will fall into the supply pipe 42 through the discharge pipe 40, and then the third servo motor 44 drives the screw rod 45 to rotate, which will drive the coarse pulverized coal or biomass fuel to be stably transported and supplied to the combustion equipment 46, thereby ensuring the continuity and stability of fuel combustion in the combustion equipment 46, thereby improving the continuity and stability of power generation, and can effectively reduce energy loss and improve the energy conversion efficiency of the entire power generation system.

[0043] It should be noted that the present invention is an intelligent multi-fuel supply device based on thermal power generation equipment. When coal is used as fuel, the coal is transported to the top of the first feed hopper 5 by a conveyor belt and then fed into the coal crushing box 4 through the first feed hopper 5. Under the action of the first guide plate 6, the coal is guided between the two crushing rollers 13. At this time, the first servo motor 8 drives the first rotating rod 9 to rotate. At this time, the first gear 10 will drive the second gear 11 meshed with it to rotate as the first rotating rod 9 rotates, and then the second rotating rod 12 can be driven to rotate. When the second rotating rod 12 rotates simultaneously, the two crushing rollers 13 will be driven to rotate. Here, the two crushing rollers 13 rotate in opposite directions. After the coal is guided to the two crushing rollers 13, the crushing rollers 13 rotate and drive the crushing teeth 14 to crush the coal. After the crushed coal blocks fall down, they pass through the feeding channel 15 and enter the coal grinding box 16. Here, when the first servo motor 8 drives the first rotating rod 9 to rotate, the third gear 17 will be driven to rotate together. When the third gear 17 rotates, it will drive the fourth gear 19 to rotate under the action of the transmission toothed belt 18, thereby driving the third rotating rod 9 to rotate. The rod 20 rotates with the worm 22. Since the worm 22 is meshed with the worm wheel 23, the rotation of the worm 22 drives the worm wheel 23 to rotate, thereby driving the fourth rotating rod 24 to rotate. When the fourth rotating rod 24 rotates, it drives the second guide plate 26 and the first rotating cylinder 27 to rotate. In this way, the coal blocks fall into the coal grinding box 16 through the feeding channel 15 and fall on the surface of the second guide plate 26. When the second guide plate 26 rotates, the coal blocks are driven to move to the edge position under the action of centrifugal force, and finally fall from the gap between the second guide plate 26 and the inner wall of the coal grinding box 16. When the first rotating cylinder 27 rotates, it will drive the two sets of fixed seats 28 to rotate, and then drive the movable rod 29 and the grinding roller 30 to rotate. In this way, the grinding roller 30 can rotate to grind the coal blocks during the falling process. The ground coarse coal powder enters the supply pipe 42 through the discharge pipe 40. The third servo motor 44 drives the screw rod 45 to rotate to supply the coal powder to the combustion equipment 46 for combustion. The large amount of heat energy generated by the combustion can be used for thermal power generation by the power generation equipment 47. After crushing and grinding, the coal can be turned into coarse coal powder, which can be fully burned.

[0044] When biomass fuel is used as fuel, the biomass fuel is conveyed to the top of the second feed hopper 32 by a conveyor belt, and then fed into the biomass fuel processing box 31 by the second feed hopper 32, and then the second servo motor 33 drives the second rotating cylinder 34 to rotate. At this time, the multiple crushing teeth 35 will crush the biomass fuel, and at the same time, the hot air blower 38 is started to blow hot air into the second rotating cylinder 34 through the air intake pipe 39, and then discharged from the multiple openings 37, so that the internal moisture of the biomass fuel can be efficiently dried when the biomass fuel is crushed. After the biomass fuel is processed, the solenoid valve 41 is opened, and the second rotating cylinder 34 is turned on. When the moving cylinder 34 rotates, it will drive the shifting plate 36 to shift the biomass fuel at the bottom of the biomass fuel processing box 31 to move. When it moves to the air inlet pipe 39, it will fall and pass through the discharge pipe 40 into the supply pipe 42. Then, the third servo motor 44 drives the screw rod 45 to rotate to supply the processed biomass fuel to the combustion equipment 46 for combustion. The particle size of the biomass fuel after crushing and drying becomes smaller and more uniform, and can be more evenly distributed in the furnace. At the same time, the specific surface area of ​​the crushed biomass fuel is increased, which is conducive to the full contact between oxygen and fuel, making the combustion reaction more stable and continuous.

[0045] Here, coal or biomass fuel can be supplied for thermal power generation according to actual needs. At the same time, coal and biomass fuel can be supplied to the combustion equipment for mixed combustion. Local crop straw can be used as biomass fuel and mixed with coal for combustion. This can not only reduce the amount of coal purchased, but also turn agricultural waste that originally needed to be processed into treasure, thereby realizing the effective use of resources.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
