Description

Technical Field

[0001] The invention relates to the technical field of boiler equipment, in particular to a power generation combustion boiler with improved combustion efficiency. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The boiler consists of two major parts: a pot and a furnace. The hot water or steam generated in the boiler can directly provide thermal energy, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] After searching, it was found that the patent document with publication number CN118408214A provides an ammonia-blended combustion boiler that can improve ignition efficiency and combustion efficiency, wherein the fuel in the furnace is continuously flipped by a flipping assembly to make the fuel loose and easy to burn, and the flipping plate in the flipping assembly always flips up and down around the rotating column.

The material receiving mechanism is used to carry fuel. The material turning mechanism cooperates with the material receiving mechanism, and rotates around the center of the furnace in the furnace body 1 to turn the material. When the material turning mechanism rotates in the furnace body 1 to turn the material, it also rotates around its own rotation axis to turn the material, so as to expand the turning range and improve the turning efficiency. The material vibrating mechanism is synchronously linked with the material turning mechanism, and the material vibrating mechanism cooperates with the material receiving mechanism to vibrate the fuel in the furnace body 1, so that gaps are exposed between the fuel to facilitate air flow.

[0036] The air supply device 2 includes a return air pipe 201, an air intake pipe 204 and an air distribution pipe 205. One end of the return air pipe 201 is inserted into the upper part of the combustion chamber 10, and the other end of the return air pipe 201 is connected to the air intake pipe 204. The air distribution pipe 205 is provided in plurality, and one end of each of the plurality of air distribution pipes 205 is connected to one end of the air intake pipe 204 through a pipeline. The plurality of air distribution pipes 205 are provided in the upper part of the ash storage chamber 11, and the upper surfaces of the plurality of air distribution pipes 205 are provided with a plurality of air outlets 2 06, a filter is arranged in the air outlet 206, and an oxygen pipe 202 and a gas pipe 203 are respectively fixed on the upper and lower sides of one end of the air inlet pipe 204, and oxygen and gas required for combustion are delivered into the air inlet pipe 204 through the oxygen pipe 202 and the gas pipe 203, and the gas flows into a plurality of air distribution pipes 205 along the pipelines and flows out from a plurality of air outlets 206 on the upper surface of the air distribution pipes 205, and the combustible gas generated in the combustion chamber 10 flows back to the air inlet pipe 204 along the return air pipe 201, and enters the furnace again through the pipeline for re-combustion and use;

[0037] The top surface of the guide platform 8 is an inwardly concave cambered surface, and its bottom surface is a plane. The bottom surface of the guide platform 8 is provided with an opening, and a receiving plate 12 is fixed in the opening. The guide platform 8 and the receiving plate 12 cooperate to form the receiving mechanism. A discharge port 13 is provided at the center of the receiving plate 12, and a baffle plate 18 is provided in the discharge port 13. A plurality of air holes 14 are provided around the periphery of the receiving plate 12 at equal intervals, and a filter screen is fixed in each of the plurality of air holes 14. The lower portion of the air holes 14 is trumpet-shaped, and the upper portion is spiral-shaped. The trumpet-shaped lower opening can conveniently receive the gas blown from the gas outlet 206, and then the gas is rotated into the furnace through the spiral upper opening to form a vortex airflow. The fuel in the furnace is blown by this vortex airflow, so that the fuel is fully in contact with the combustion-supporting gas, and at the same time, the fuel dust is blown up to make the dust fully burn;

[0038] The outer side of the material guide platform 8 is evenly surrounded by a plurality of slide grooves 15, and a slider 19 is fixed on one side of the furnace body 1 corresponding to the plurality of slide grooves 15, and the slider 19 is slidably connected to the slide groove 15. The material guide platform 8 is slidably connected to the furnace body 1 through the cooperation of the slider 19 and the slide groove 15. To ensure stability during sliding, a slide rod 16 is fixed in the slide groove 15, and the slide rod 16 is slidably inserted in the slider 19, and both ends of the slide rod 16 are sleeved with a first spring 17, one end of each of the two first springs 17 is connected and fixed to the slider 19, and the other ends of each of the two first springs 17 is connected and fixed to the inner wall of one side of the slide groove 15;

[0039] The first spring 17 can be used to reset the material guide platform 8 after sliding up and down. By continuously sliding up and down and resetting, the material guide platform 8 vibrates, and the vibration is also transmitted to the furnace body 1. The furnace body 1 and the material guide platform 8 vibrate synchronously. When the furnace body 1 vibrates, the fuel attached to the inner wall of the furnace body will be shaken off onto the material guide platform 8. The curved surface on the top of the material guide platform 8 can facilitate the fuel to continue to roll down to the material receiving plate 12. When the material guide platform 8 vibrates, it can promote the fuel to roll downward. At the same time, the material guide platform 8 will also drive the material receiving plate 12 to vibrate synchronously, and shake the fuel residue or ashes stuck in the air hole 14 into the ash storage chamber 11, so as to keep the air hole 14 unobstructed.

[0040] See also Figures 8 to 10 A driving ring 20 is rotatably connected to the upper part of the motor chamber 9, and a plurality of protrusions 21 are fixed around the bottom of the driving ring 20 at equal intervals. A dual-axis synchronous motor 25 is installed in the middle position of the motor chamber 9, and one end of the rotating shaft of the driving ring 20 is connected and fixed to one end of the output shaft of the dual-axis synchronous motor 25. A slide 23 is fixed to one side of the heat insulation board 7 corresponding to the plurality of protrusions 21, and a connecting rod 24 is slidably connected in the slide 23, and one end of the connecting rod 24 extends to one side of the driving ring 20. The top end of the connecting rod 24 is rotatably connected with a roller 22, and the roller 22 abuts against the driving ring 20. The number and position of the roller 22 correspond to the number and position of the protrusion 21. The other end of the connecting rod 24 extends downward to one side of the material guide platform 8, and the bottom end of the connecting rod 24 abuts against the material guide platform 8. A second spring 26 is arranged inside the slide 23, and one end of the second spring 26 is sleeved and fixed on the connecting rod 24, and the other end of the second spring 26 is fixed on the inner wall of the slide 23.

[0041] When the driving ring 20 rotates, the roller 22 will be squeezed and move downward after contacting the protrusion 21, thereby driving the connecting rod 24 to move downward synchronously, and the bottom end of the connecting rod 24 contacts the material guide platform 8. At this time, the material guide platform 8 will also be squeezed and move downward. After the roller 22 disengages from the protrusion 21, it will reset upward under the action of the second spring 26, driving the connecting rod 24 to move upward synchronously. The bottom end of the connecting rod 24 no longer squeezes the material guide platform 8, and the material guide platform 8 resets upward under the action of the first spring 17. By continuously rotating the driving ring 20, the connecting rod 24 is periodically moved up and down, thereby driving the material guide platform 8 to slide up and down continuously, causing the material guide platform 8 to vibrate. The driving ring 20, the protrusion 21, the roller 22, the connecting rod 24 and other components cooperate to constitute the vibration mechanism.

[0042] See also Figures 11-12A fixed gear 28 is fixed at the middle position of the bottom of the heat insulation board 7, a triangular bracket 30 is arranged at the bottom of the fixed gear 28, a rotating shaft 31 is fixed at the center of the triangular bracket 30, a shaft sleeve 29 is fixed at the center of the fixed gear 28, one end of the rotating shaft 31 is rotatably connected to the shaft sleeve 29, and the top end of the rotating shaft 31 rotates through the heat insulation board 7 and extends to the motor chamber 9, the top end of the rotating shaft 31 is connected and fixed to one end of the output shaft of the dual-axis synchronous motor 25, and the rotating shaft 31 can be rotated by the dual-axis synchronous motor 25 to drive the triangular bracket 30 to rotate synchronously;

[0043] The upper surface of the triangular bracket 30 is rotatably connected with a plurality of driving gears 32 at equal intervals corresponding to the outer side of the fixed gear 28, and the plurality of driving gears 32 are all meshed and connected with the fixed gear 28. The lower surface of the triangular bracket 30 is rotatably connected with a linkage gear 33 corresponding to one side of the plurality of driving gears 32, and the linkage gear 33 is coaxially fixed with the corresponding driving gear 32. When the driving gear 32 rotates, the linkage gear 33 will also rotate synchronously.

[0044] A first driven gear 35 is rotatably connected to one side of the lower surface of the triangular bracket 30 corresponding to the plurality of linkage gears 33. The first driven gear 35 is meshed and connected with the corresponding linkage gear 33. A crank 34 is disposed on one side of the lower surface of the triangular bracket 30 corresponding to the plurality of first driven gears 35. The bottom end of the rotating shaft of the first driven gear 35 is fixed to the crank 34. When the first driven gear 35 rotates, the crank 34 is driven to rotate synchronously.

[0045] A second driven gear 36 is rotatably connected to one end of the upper surface of the crank 34, and the second driven gear 36 is meshed and connected with the corresponding first driven gear 35. A flipping plate 27 is provided on the side of the crank 34 corresponding to the second driven gear 36. The flipping plate 27 is composed of a rotating shaft and a plurality of vertical plates uniformly fixed around the rotating shaft. The rotating shaft of the flipping plate 27 is connected and fixed to the rotating shaft of the second driven gear 36.

[0046] In this embodiment, the triangular bracket 30, the gear, the crank 34 and the flipping plate 27 cooperate with each other to form the flipping mechanism. When the dual-axis synchronous motor 25 drives the triangular bracket 30 to rotate, the multiple flipping plates 27 arranged below the triangular bracket 30 will rotate around the rotating shaft 31. At this time, the flipping plate 27 will perform a large revolution in the furnace with the rotating shaft 31 as the center to flip the material. At the same time, the triangular bracket 30 will also drive the multiple driving gears 32 to revolve around the rotating shaft 31. Since the fixed gear 28 is fixed and the driving gear 32 is meshed with the fixed gear 28, when the driving gear 32 revolves, it will also rotate around its own axis.

[0047] The driving gear 32 is coaxially fixed with the linkage gear 33. When the driving gear 32 rotates, the linkage gear 33 will also rotate synchronously. The linkage gear 33 is meshed with the first driven gear 35. The bottom end of the rotating shaft of the first driven gear 35 is fixed to the crank 34. When the linkage gear 33 drives the first driven gear 35 to rotate, the first driven gear 35 will also drive the crank 34 to rotate synchronously. The turning plate 27 arranged below the crank 34 will rotate around the rotating shaft of the first driven gear 35. At this time, the turning plate 27 will turn the material in the furnace with a small revolution around the rotating shaft of the first driven gear 35 as the center.

[0048] The second driven gear 36 at the upper end of the crank 34 is meshed with the first driven gear 35. When the first driven gear 35 rotates, it will drive the second driven gear 36 to rotate synchronously. One end of the rotating shaft of the flipping plate 27 is fixed to the rotating shaft of the second driven gear 36. When the second driven gear 36 rotates, the flipping plate 27 will also rotate. At this time, the flipping plate 27 will rotate around its own rotating shaft and flip the material. The combination of large revolution flipping, small revolution flipping and self-rotation flipping acts on the fuel in the furnace synchronously, so that the fuel is fully flipped, and the pores between the fuels can be fully opened, ensuring that the combustion-supporting gas can circulate smoothly between the fuels, thereby allowing the fuel to be fully burned.
