Description

Technical Field

[0001] This invention relates to the field of boiler technology, specifically to a boiler structure with dual-medium dual-temperature heating. Background Technology

[0002] Dual-medium dual-temperature heating boilers achieve efficient and flexible heating by using dual media, such as water and thermal oil, or water and steam, and a dual-temperature zone design. Because of their dual-temperature and dual-control capabilities, they can simultaneously output two media at different temperatures, meeting the combined needs of industrial heating and residential heating. In fields such as metal smelting, ceramic sintering, and semiconductor manufacturing, the dual-temperature zone design enables precise temperature control, solving problems such as uneven temperature and oxidation defects in traditional single-temperature zone furnaces. This makes them widely used in industrial fields, civil buildings, heating in cold regions, precision temperature control in laboratories, and high-temperature and high-pressure scientific research.

[0003] In existing technologies, boilers with dual-medium dual-temperature heating systems typically place coal on a fixed grate for static combustion. This causes the ash produced during static combustion to easily melt and agglomerate in the high-temperature zone, forming dense, large clumps of coke slag. This obstructs ventilation, leading to uneven resistance in the firebed, resulting in air distribution imbalance and a sharp drop in combustion efficiency. Consequently, a large amount of unburned carbon is discharged with the slag, causing severe heat loss. Furthermore, uneven combustion easily leads to fluctuations in the furnace temperature field, making it difficult for the dual-medium system with a stable heat source to maintain precise temperature and pressure parameters, thus affecting the quality of heating. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in dual-medium dual-temperature heating boilers, coal is typically placed on a fixed grate for static combustion. This static combustion causes ash to easily melt and agglomerate in the high-temperature zone, forming dense, large clumps of coke slag. This obstructs ventilation, leads to uneven firebed resistance, and results in air distribution imbalance and a sharp drop in combustion efficiency. Consequently, a large amount of unburned carbon is discharged with the slag, causing severe heat loss. Furthermore, uneven combustion easily leads to fluctuations in the furnace temperature field, making it difficult for the dual-medium system with a stable heat source to maintain precise temperature and pressure parameters, thus affecting the quality of heating.

[0009] In a preferred embodiment of the present invention, a pair of rotating rods three are rotatably connected to one side of the outer wall of the boiler body, and one end of the outer wall of the pair of rotating rods three extends into the boiler body; a set of vibrating balls are fixedly connected to the outer side wall of the pair of rotating rods three through a set of flexible rods; a gear four is fixedly connected to the outer side wall of the rotating rod two; a gear five is fixedly connected to the outer side wall of the pair of rotating rods three, and the pair of gear five meshes with the gear four.

[0012] In a preferred embodiment of the present invention, a charcoal crushing shell is fixedly connected to the top of the outer wall of the feed shell, and the charcoal crushing shell is in communication with the feed shell; a rotating rod eight and a rotating rod nine are rotatably connected to one side of the inner wall of the charcoal crushing shell, and one end of the outer wall of both the rotating rod eight and the rotating rod nine penetrates the charcoal crushing shell; a gear eight is fixedly connected to the outer wall of both the rotating rod eight and the rotating rod nine, and a pair of gears eight mesh with each other; a sprocket eight is fixedly connected to the outer wall of both the metering rod and the rotating rod eight, and a pair of sprockets eight mesh with each other through a chain eight; a charcoal crushing roller is fixedly connected to the outer wall of both the rotating rod eight and the rotating rod nine; a pair of guide plates are fixedly connected to the inner wall of the feed shell, and the pair of guide plates are matched with a pair of charcoal crushing rollers.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The motor drives the rotating shaft and bevel gear two to rotate, which in turn drives the rotating rod through bevel gear one. The rotating rod then drives the stirring plate to agitate the coal. During the agitation process, the coal is in a dynamic combustion state, which effectively avoids the problem of ash melting and sticking together in the high-temperature zone to form large pieces of coke slag, which is a problem in static combustion. Dynamic combustion also allows the coal to come into more full contact with the air, significantly improving ventilation, uniform firebed resistance, and more reasonable air distribution, thereby improving combustion efficiency. This not only reduces heat loss caused by unburned carbon being discharged with the slag, but also makes the furnace temperature field more stable due to uniform combustion. The dual-medium system can accurately maintain temperature and pressure parameters, effectively improving the quality of heating.

[0014] 2. When the circular rod rotates, it drives a pair of rotating rods to rotate through the transmission action of sprocket one and chain one. This causes the upper and lower crushing rollers to rotate relative to each other in the second through groove. This allows the upper and lower crushing rollers to effectively crush any large or lumpy pieces of coal encountered during dynamic combustion and tumbling. This further increases the contact area between the coal and air, optimizes ventilation, and ensures that the coal can burn more fully and evenly. Because sprocket one and chain one are located in the hollow groove, they provide good protection and sealing, preventing impurities generated during coal combustion from entering the transmission mechanism and ensuring the stable operation of the crushing structure.

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please see Figures 1-10 As shown, a boiler structure for dual-medium dual-temperature heating includes a boiler body 1; a grate body 2 is provided on the inner wall of the boiler body 1; a motor 3 is fixedly connected to one side of the outer wall of the boiler body 1 via a fixing block; a rotating shaft 4 is provided at the output end of the motor 3; a rotating rod 6 is rotatably connected to the inner wall of the boiler body 1 via a square plate 5; a set of stirring plates 7 is fixedly connected to the outer wall of the rotating rod 6; a bevel gear 8 is fixedly connected to the top of the outer wall of the rotating rod 6; one end of the outer wall of the rotating shaft 4 extends into the boiler body 1, and a bevel gear 9 is fixedly connected to one end of the outer wall of the rotating shaft 4; the bevel gear 9 meshes with the bevel gear 8.

[0019] The boiler body 1 is a dual-medium dual-temperature heating boiler, which is existing technology and will not be described in detail. Coal is placed on the grate body 2. When coal combustion is required, the motor 3 drives the rotating shaft 4 and the second bevel gear 9 to rotate. The second bevel gear 9 drives the rotating rod 6 through the first bevel gear 8 to rotate. The rotating rod 6 drives the stirring plate 7 to stir the coal. During the stirring process, the coal is in a dynamic combustion state, which effectively avoids the problem of ash melting and agglomerating in the high-temperature zone to form large pieces of coke slag during static combustion. Dynamic combustion allows the coal to come into more full contact with air, significantly improving ventilation. The resistance of the fire bed is uniform, and the air distribution is more reasonable, thereby improving combustion efficiency. It not only reduces the heat loss caused by unburned carbon being discharged with the slag, but also makes the furnace temperature field more stable due to uniform combustion. The dual-medium system can accurately maintain temperature and pressure parameters, effectively improving the heating quality.

[0020] An inclined plate 101 is fixedly connected to the inner wall of the boiler body 1; a feed shell 102 is fixedly connected to one side of the outer wall of the boiler body 1, and the feed shell 102 matches the inclined plate 101; a metering rod 103 is rotatably connected to one side of the inner wall of the feed shell 102, and one end of the outer wall of the metering rod 103 penetrates the feed shell 102; a set of metering plates 104 are fixedly connected to the outer wall of the metering rod 103; sprockets 105 are fixedly connected to the outer walls of both the metering rod 103 and the rotating shaft 4, and a pair of sprockets 105 are connected by a chain 106, so that the rotation... Shaft 4 drives the metering rod 103 to rotate via sprocket 5 105 and chain 5 106. The metering rod 103 drives a set of metering plates 104 to rotate, so that the coal put into the feed shell 102 is metered and transported to the inclined plate 101 during the rotation of the metering plate 104, and then falls down onto the grate body 2 along the inclined plate 101. This achieves precise control of the amount of coal entering the grate body 2, avoiding problems such as incomplete combustion and excessively high local temperature caused by a large amount of coal entering at once. At the same time, metered feeding can also ensure that the coal is more evenly distributed on the grate body 2, providing good initial conditions for the subsequent dynamic combustion process, and further improving the combustion efficiency and heating quality of coal.

[0021] A sealing shell 10 is fixedly connected to the top of the outer wall of the square plate 5, and both bevel gear 8 and bevel gear 9 are located inside the sealing shell 10; the rotating rod 6 and the rotating shaft 4 are both rotatably connected to the sealing shell 10; a pair of first through slots 701 are opened on one side of the outer wall of the stirring plate 7; a circular rod 702 is rotatably connected to one side of the outer wall of the stirring plate 7, and one end of the outer wall of the circular rod 702 extends into the first through slot 701; two sets of flipping plates 703 are fixedly connected to the outer wall of the circular rod 702, and the two sets of flipping plates 703 are respectively located in a pair of first through slots 701; a gear 704 is fixedly connected to one end of the outer wall of the circular rod 702; an annular rack 705 is fixedly connected to the inner wall of the boiler body 1 through a pair of connecting blocks, and the annular rack 705 meshes with a set of gears 704; an annular shell 706 is rotatably connected to the bottom of the outer wall of the annular rack 705, and the annular shell 706 is rotatably connected to a set of circular rods 702.

[0022] With both bevel gear 8 and bevel gear 9 located within the sealing housing 10, the gear transmission structure is well-sealed and protected, effectively preventing dust, particles, and other impurities generated by coal combustion from entering the meshing parts of bevel gear 8 and bevel gear 9, causing problems such as gear wear and jamming, thus improving the transmission stability and service life of bevel gear 8 and bevel gear 9.

[0023] The stirring plate 7 has a first through groove 701 and is equipped with a circular rod 702, a tilting plate 703, and a gear 704. When the stirring plate 7 rotates with the rotating rod 6, it drives the circular rod 702 and the gear 704 to rotate. Since the gear 704 meshes with the ring rack 705 and the ring rack 705 is fixed, the rotation of the gear 704 causes the circular rod 702 to rotate, which in turn causes the tilting plate 703 to tilt within the first through groove 701. This ensures that during dynamic combustion, the coal is not only horizontally agitated by the stirring plate 702 but also by the tilting plate 703. 3. The up-and-down tumbling action allows the coal to tumble and mix thoroughly, further increasing the contact area with air and enhancing ventilation. This results in more complete and uniform coal combustion, further reducing the generation of unburned carbon and improving combustion efficiency. It also makes the temperature field inside the furnace more uniform and stable, providing a stronger guarantee for the dual-medium system to accurately maintain temperature and pressure parameters, thereby comprehensively improving the heating quality. The annular shell 706, which is rotatably connected to the bottom of the outer wall of the ring rack 705, and the rotatable connection with a set of circular rods 702, also play a role in sealing and protection, ensuring that the entire tumbling structure can operate stably and reliably.

[0024] A pair of hollow grooves 707 are provided inside the agitator plate 7; a pair of second through grooves 708 are provided on one side of the outer wall of the agitator plate 7, and the pair of second through grooves 708 are staggered with a pair of first through grooves 701; a rotating rod 709 is rotatably connected to one side of the inner wall of each pair of hollow grooves 707, and one end of the outer wall of each pair of rotating rods 709 extends into the pair of second through grooves 708; a pair of upper crushing rollers 7010 are fixedly connected to the outer wall of the circular rod 702, and the pair of upper crushing rollers 7010 are respectively located in the pair of second through grooves 708; a lower crushing roller 7011 is fixedly connected to the outer wall of each pair of rotating rods 709, and the pair of lower crushing rollers 7011 are respectively matched with the pair of upper crushing rollers 7010; the circular rod 702 and the pair of rotating rods 709 are connected by a sprocket 7012 and a chain 7013, and the pair of chains 7013 are respectively located in the pair of hollow grooves 707.

[0025] When the circular rod 702 rotates, it drives a pair of rotating rods 709 to rotate through the transmission action of sprocket 7012 and chain 7013. This causes the upper crushing roller 7010 and the lower crushing roller 7011 to rotate relative to each other within the second through groove 708. This allows the upper crushing roller 7010 and the lower crushing roller 7011 to effectively crush any large or lumpy pieces of coal encountered during dynamic combustion and tumbling. This further increases the contact area between the coal and air, optimizes ventilation, and ensures that the coal can burn more fully and evenly. Because sprocket 7012 and chain 7013 are located within the hollow groove 707, they provide good protection and sealing, preventing impurities generated during coal combustion from entering the transmission mechanism and ensuring the stable operation of the crushing structure.

[0026] The rotating rod 6 includes a rod body 601 and a housing 602; the outer side wall of the rod body 601 is slidably connected to the inner side wall of the housing 602; the bottom end of the outer side wall of the rod body 601 is rotatably connected to the top end of the outer side wall of the grate body 2; the outer side wall of the grate body 2 is slidably connected to the inner side wall of the boiler body 1; a rotating rod 20 is rotatably connected to one side of the outer side wall of the boiler body 1, and one end of the outer side wall of the rotating rod 20 extends into the boiler body 1; an elliptical block 21 is fixedly connected to the outer side wall of the rotating rod 20, and the elliptical block 21 is in contact with the grate body 2; a sprocket 22 is fixedly connected to both the outer side wall of the rotating rod 20 and the outer side wall of the rotating shaft 4, and a pair of sprockets 22 are connected by a chain 23.

[0027] When the rotating shaft 4 rotates, it drives the rotating rod 20 to rotate via the sprocket 22 and chain 23. The rotating rod 20 drives the elliptical block 21 to rotate. Since the elliptical block 21 is in contact with the grate body 2, it periodically squeezes the grate body 2 during rotation, causing the grate body 2 to slide back and forth on the inner wall of the boiler body 1. This allows the coal placed on the grate body 2 to continuously change position, preventing coal from accumulating in local areas for a long time and further promoting dynamic combustion. At the same time, the reciprocating motion of the grate body 2 also makes the coal more evenly distributed during combustion, ensuring that the coal is fully in contact with the air, resulting in smoother ventilation, more uniform firebed resistance, and more precise and reasonable air distribution. This not only further improves the combustion efficiency of coal and reduces the emission of unburned carbon and heat loss, but also prevents coke slag from clogging the grate body 2, ensuring the ventilation effect of the grate body 2.

[0028] When the grate body 2 moves up and down, the rotating rod 6, including the rod body 601 and the housing 602, causes the grate body 2 to move the rod body 601, and the rod body 601 slides inside the housing 602.

[0029] A circular shell 40 is fixedly connected to one side of the outer wall of the boiler body 1, and the circular shell 40 is connected to the boiler body 1; a filter screen 41 is provided at the connection between the circular shell 40 and the boiler body 1; a rotating rod 42 is rotatably connected to one side of the outer wall of the circular shell 40, and one end of the outer wall of the rotating rod 42 extends into the circular shell 40; a set of fan blades 43 is fixedly connected to the outer wall of the rotating rod 42; gears 44 are fixedly connected to the outer walls of both the rotating rod 42 and the rotating rod 20, and a pair of gears 44 mesh with each other.

[0030] Gears 44 are fixed to the outer walls of both rotating rod 5 (42) and rotating rod 2 (20), and the two gears 44 mesh with each other. The rotation of rotating rod 2 (20) drives rotating rod 5 (42) to rotate through the gears 44. The rotation of rotating rod 5 (42) drives the fan blades 43 to rotate. The rotation of fan blades 43 generates wind power, which passes through the filter screen 41 and enters the grate body 2, promoting the combustion of coal on the grate body 2. The filter screen 41 effectively blocks larger particulate impurities generated during coal combustion from entering the circular shell 40 and damaging the fan blades 43 and other structures, ensuring the stable operation of the fan blades 43 and the continuous generation of wind power. The wind power blows onto the coal on the grate body 2, providing sufficient oxygen for coal combustion and further enhancing the ventilation effect, allowing the coal to burn fully in a more oxygen-rich environment. Since the rotation of rotating rod 2 (20) drives the rotation of rotating rod 5 (42) to generate wind power, the existing power structure inside the boiler is utilized, eliminating the need for additional complex power devices, reducing equipment costs and energy consumption, and improving the economy and practicality of the entire boiler system.

[0031] A pair of rotating rods 30 are rotatably connected to one side of the outer wall of the boiler body 1, and one end of the outer wall of the pair of rotating rods 30 extends into the boiler body 1; a set of vibrating balls 31 are fixed to the outer wall of the pair of rotating rods 30 through a set of flexible rods; a gear 4 32 is fixed to the outer wall of the rotating rod 20; a gear 5 33 is fixed to the outer wall of the pair of rotating rods 30, and the pair of gears 5 33 mesh with the gear 4 32.

[0032] The rotation of the rotating rod 20 drives the gear 4 32 to rotate. The rotation of the gear 4 32 drives the rotation of the rotating rod 30 through a pair of gears 5 33. The rotation of the rotating rod 30 drives the vibrating ball 31 to rotate through the flexible rod. When the grate body 2 moves downward to a certain extent, the vibrating ball 31 strikes the grate body 2, producing a vibration effect. This prevents the coke produced during coal combustion from adhering to the grate body 2, avoiding the accumulation of coke and blockage. It ensures that the ventilation holes of the grate body 2 remain unobstructed and maintains good ventilation. The striking action of the vibrating ball 31 also loosens the coal on the grate body 2, promoting coal turning and mixing, allowing for more sufficient contact between coal and air, further optimizing the combustion process. At the same time, the vibration, the reciprocating sliding of the grate body 2, and the stirring, turning, and crushing of the coal work together to form a comprehensive, multi-layered dynamic combustion system. This ensures that the coal is in the optimal combustion state throughout the entire combustion process, maximizing combustion efficiency, reducing the emission of unburned carbon, and reducing heat loss.

[0033] Example 2: Please see Figures 1-2 and Figures 9-10 As shown, a charcoal crushing shell 107 is fixedly connected to the top of the outer wall of the feed shell 102, and the charcoal crushing shell 107 is connected to the feed shell 102; a rotating rod 108 and a rotating rod 109 are rotatably connected to one side of the inner wall of the charcoal crushing shell 107, and one end of the outer wall of both the rotating rod 108 and the rotating rod 109 penetrates the charcoal crushing shell 107; gears 1010 are fixedly connected to the outer walls of both the rotating rod 108 and the rotating rod 109, and a pair of gears 1010 are connected to each other. 010 are mutually meshed; the outer walls of the metering rod 103 and the rotating rod 108 are both fixedly connected to sprockets 1011, and the pair of sprockets 1011 mesh with each other through chain 1012; the outer walls of the rotating rod 108 and the rotating rod 109 are both fixedly connected to carbon crushing rollers 1013; the inner wall of the feed shell 102 is fixedly connected to a pair of guide plates 1014, and the pair of guide plates 1014 are matched with the pair of carbon crushing rollers 1013.

[0034] Both the metering rod 103 and the rotating rod 108 have sprockets 1011 fixed to their outer walls. These sprockets mesh with each other via chains 1012, causing the metering rod 103 to rotate via the sprockets 1011 and chains. The rotating rod 108 then rotates via a pair of meshing gears 1010, which in turn rotates the rotating rod 109. This causes the pair of coal crushing rollers 1013 to rotate relative to each other. When coal enters the coal crushing shell 107, it is guided by a pair of guide plates 1014 and... The coal is fed between a pair of crushing rollers 1013. The relatively rotating crushing rollers 1013 will squeeze and crush the coal, breaking larger pieces of coal into smaller particles. This further increases the contact area between the coal and the air, optimizing the subsequent combustion effect. After being crushed, the coal falls onto the grate body 2 along the feed shell 102 and the inclined plate 101, providing more favorable conditions for the complete combustion of the coal. This helps to improve combustion efficiency, reduce the generation of unburned carbon, and thus improve the heating quality of the entire boiler system.

[0035] In use, coal is placed in the charcoal shell 107, and falls onto the grate body 2 through the charcoal shell 107, the feed shell 102, and the inclined plate 101. When coal combustion is required, the motor 3 drives the rotating shaft 4 and the second bevel gear 9 to rotate. The second bevel gear 9 drives the rotating rod 6 to rotate through the first bevel gear 8. The rotating rod 6 drives the stirring plate 7 to stir the coal. During the stirring process, the coal is in a dynamic combustion state, which effectively avoids the problem of ash melting and agglomerating in the high-temperature zone to form large pieces of coke slag during static combustion. Dynamic combustion allows the coal to come into more full contact with the air, significantly improving ventilation, uniform firebed resistance, and more reasonable air distribution, thereby improving combustion efficiency. It not only reduces heat loss caused by unburned carbon being discharged with the slag, but also makes the furnace temperature field more stable due to uniform combustion. The dual-medium system can accurately maintain temperature and pressure parameters, effectively improving the heating quality.

[0036] With both bevel gear 8 and bevel gear 9 located within the sealing housing 10, the gear transmission structure is well-sealed and protected, effectively preventing dust, particles, and other impurities generated by coal combustion from entering the meshing parts of bevel gear 8 and bevel gear 9, causing problems such as gear wear and jamming, thus improving the transmission stability and service life of bevel gear 8 and bevel gear 9.

[0037] Since both the metering rod 103 and the outer wall of the rotating shaft 4 are fixedly connected with sprockets 105, and a pair of sprockets 105 are connected by a chain 106, the rotating shaft 4 drives the metering rod 103 to rotate through the sprockets 105 and the chain 106. The metering rod 103 drives a set of metering plates 104 to rotate, so that the coal put into the feed shell 102 is metered and transported to the inclined plate 101 during the rotation of the metering plate 104, and then falls down onto the grate body 2 along the inclined plate 101. This achieves precise control of the amount of coal entering the grate body 2, avoiding problems such as incomplete combustion and excessively high local temperature caused by a large amount of coal entering at once. At the same time, metered feeding can also ensure that the coal is more evenly distributed on the grate body 2, providing good initial conditions for the subsequent dynamic combustion process, and further improving the combustion efficiency and heating quality of coal.

[0038] Since both the metering rod 103 and the rotating rod 108 have sprockets 1011 fixed to their outer walls, and the sprockets 1011 mesh with each other via a chain 1012, the metering rod 103 drives the rotating rod 108 to rotate via the sprockets 1011 and chain 1012. The rotating rod 108 then drives the rotating rod 109 to rotate via a pair of meshing gears 1010, which in turn causes the pair of coal crushing rollers 1013 to rotate relative to each other. When coal enters the coal crushing shell 107, it will be guided by a pair of guide plates 1014 and move forward... The coal is fed between a pair of crushing rollers 1013. The relatively rotating crushing rollers 1013 will squeeze and crush the coal, breaking larger pieces of coal into smaller particles. This further increases the contact area between the coal and the air, optimizing the subsequent combustion effect. After being crushed, the coal falls onto the grate body 2 along the feed shell 102 and the inclined plate 101, providing more favorable conditions for the complete combustion of the coal. This helps to improve combustion efficiency, reduce the generation of unburned carbon, and thus improve the heating quality of the entire boiler system.

[0039] The stirring plate 7 has a first through groove 701 and is equipped with a circular rod 702, a tilting plate 703, and a gear 704. When the stirring plate 7 rotates with the rotating rod 6, it drives the circular rod 702 and the gear 704 to rotate. Since the gear 704 meshes with the ring rack 705 and the ring rack 705 is fixed, the rotation of the gear 704 causes the circular rod 702 to rotate, which in turn causes the tilting plate 703 to tilt within the first through groove 701. This ensures that during dynamic combustion, the coal is not only horizontally agitated by the stirring plate 702 but also by the tilting plate 703. 3. The up-and-down tumbling action allows the coal to tumble and mix thoroughly, further increasing the contact area with air and enhancing ventilation. This results in more complete and uniform coal combustion, further reducing the generation of unburned carbon and improving combustion efficiency. It also makes the temperature field inside the furnace more uniform and stable, providing a stronger guarantee for the dual-medium system to accurately maintain temperature and pressure parameters, thereby comprehensively improving the heating quality. The annular shell 706, which is rotatably connected to the bottom of the outer wall of the ring rack 705, and the rotatable connection with a set of circular rods 702, also play a role in sealing and protection, ensuring that the entire tumbling structure can operate stably and reliably.

[0040] When the circular rod 702 rotates, it drives a pair of rotating rods 709 to rotate through the transmission action of sprocket 7012 and chain 7013. This causes the upper crushing roller 7010 and the lower crushing roller 7011 to rotate relative to each other within the second through groove 708. This allows the upper crushing roller 7010 and the lower crushing roller 7011 to effectively crush any large or lumpy pieces of coal encountered during dynamic combustion and tumbling. This further increases the contact area between the coal and air, optimizes ventilation, and ensures that the coal can burn more fully and evenly. Because sprocket 7012 and chain 7013 are located within the hollow groove 707, they provide good protection and sealing, preventing impurities generated during coal combustion from entering the transmission mechanism and ensuring the stable operation of the crushing structure.

[0041] When the rotating shaft 4 rotates, it drives the rotating rod 20 to rotate via the sprocket 22 and chain 23. The rotating rod 20 drives the elliptical block 21 to rotate. Since the elliptical block 21 is in contact with the grate body 2, it periodically squeezes the grate body 2 during rotation, causing the grate body 2 to slide back and forth on the inner wall of the boiler body 1. This allows the coal placed on the grate body 2 to continuously change position, preventing coal from accumulating in local areas for a long time and further promoting dynamic combustion. At the same time, the reciprocating motion of the grate body 2 also makes the coal more evenly distributed during combustion, ensuring that the coal is fully in contact with the air, resulting in smoother ventilation, more uniform firebed resistance, and more precise and reasonable air distribution. This not only further improves the combustion efficiency of coal and reduces the emission of unburned carbon and heat loss, but also prevents coke slag from clogging the grate body 2, ensuring the ventilation effect of the grate body 2.

[0042] The rotation of the rotating rod 20 drives the gear 4 32 to rotate. The rotation of the gear 4 32 drives the rotation of the rotating rod 30 through a pair of gears 5 33. The rotation of the rotating rod 30 drives the vibrating ball 31 to rotate through the flexible rod. When the grate body 2 moves downward to a certain extent, the vibrating ball 31 strikes the grate body 2, producing a vibration effect. This prevents the coke produced during coal combustion from adhering to the grate body 2, avoiding the accumulation of coke and blockage. It ensures that the ventilation holes of the grate body 2 remain unobstructed and maintains good ventilation. The striking action of the vibrating ball 31 also loosens the coal on the grate body 2, promoting coal turning and mixing, allowing for more sufficient contact between coal and air, further optimizing the combustion process. At the same time, the vibration, the reciprocating sliding of the grate body 2, and the stirring, turning, and crushing of the coal work together to form a comprehensive, multi-layered dynamic combustion system. This ensures that the coal is in the optimal combustion state throughout the entire combustion process, maximizing combustion efficiency, reducing the emission of unburned carbon, and reducing heat loss.

[0043] Gears 44 are fixed to the outer walls of both rotating rod 5 (42) and rotating rod 2 (20), and the two gears 44 mesh with each other. The rotation of rotating rod 2 (20) drives rotating rod 5 (42) to rotate through the gears 44. The rotation of rotating rod 5 (42) drives the fan blades 43 to rotate. The rotation of fan blades 43 generates wind power, which passes through the filter screen 41 and enters the grate body 2, promoting the combustion of coal on the grate body 2. The filter screen 41 effectively blocks larger particulate impurities generated during coal combustion from entering the circular shell 40 and damaging the fan blades 43 and other structures, ensuring the stable operation of the fan blades 43 and the continuous generation of wind power. The wind power blows onto the coal on the grate body 2, providing sufficient oxygen for coal combustion and further enhancing the ventilation effect, allowing the coal to burn fully in a more oxygen-rich environment. Since the rotation of rotating rod 2 (20) drives the rotation of rotating rod 5 (42) to generate wind power, the existing power structure inside the boiler is utilized, eliminating the need for additional complex power devices, reducing equipment costs and energy consumption, and improving the economy and practicality of the entire boiler system.
