[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-4 The utility model provides an embodiment: a three-dimensional layered combustion structure of a boiler, including a boiler body 1, an ash box 9 is fixedly connected to the bottom end of the boiler body 1, an isolation cover 16 is fixedly connected to the middle of the inner wall of the boiler body 1, a vibrator 4 is fixedly connected to the left side of the front end of the boiler body 1, a first sieve plate 12 is fixedly connected to the upper side of the left end of the inner wall of the boiler body 1, a second sieve plate 13 is fixedly connected to the middle of the left end of the inner wall of the boiler body 1, and a baffle 5 is slidably connected to the lower side of the left end of the inner wall of the boiler body 1. The crushed coal ash first falls on the first sieve plate 12. At this time, the vibrator 4 is started, so that the left side of the boiler body 1 Side vibration, through the conduction effect of vibration, the first sieve plate 12 is shaken to screen the coal, and the coal with smaller particles will fall to the top of the second sieve plate 13 to continue shaking and screening, and finer coal particles will fall to the top of the baffle 5. The left end of the boiler body 1 is successively close to the first sieve plate 12, the second sieve plate 13 and the upper side of the baffle 5, and the burner 3 is fixedly connected. Start the burner 3 on the left side to burn the coal in each layer. The heat generated by the combustion will be transferred to the medium in the inner cavity on the right side of the boiler body 1 through the isolation cover 16, so that it generates heat and produces steam for heating or industrial power generation.
[0025] Specifically, the processing bucket 2 is fixedly connected to the left side of the top of the boiler body 1, and the cover plate 21 together with the clamping plate 20 is removed from the top of the processing bucket 2, and then the coal is thrown into the processing bucket 2 by using the conveying mechanism. The left and right sides of the front end of the processing bucket 2 are fixedly connected with the motor 19, and the inner wall at the top of the processing bucket 2 is clamped with a clamping plate 20. The top of the clamping plate 20 is fixedly connected with the cover plate 21. The distance between the left and right ends of the cover plate 21 is larger than the left and right ends of the processing bucket 2. The left and right sides of the inner wall at the rear end of the processing bucket 2 are rotatably connected with the transmission rod 17. The front ends of the transmission rod 17 penetrate the outer wall of the processing bucket 2 and are fixedly connected to the driving end of the motor 19. The outer wall of the transmission rod 17 is fixedly connected with the crushing roller 18. The motors 19 on both sides are started, so that the transmission rod 17 drives the corresponding crushing roller 18 to rotate toward the opposite side, so as to crush the coal to make it more delicate and the combustion energy is more sufficient.
[0026] Specifically, the front and rear ends of the baffle 5 are slidably connected with inclined plates 15, and the opposite ends of the inclined plates 15 are respectively fixedly connected to the left inner walls of the front and rear ends of the boiler body 1. The lower side of the left end of the boiler body 1 is fixedly connected to a hydraulic rod 8, and the driving end of the hydraulic rod 8 is fixedly connected to a connecting plate 7. The upper side of the right end of the connecting plate 7 is fixedly connected to a connecting rod 6, and the right end of the connecting rod 6 is fixedly connected to the left end of the baffle 5. After the combustion is completed, the hydraulic rod 8 is started to push the connecting plate 7 to move to the left, and at the same time drive the connecting rod 6 to pull the baffle 5 out of the boiler body 1, so that the coal ash after combustion falls from the boiler body 1 to the collection box 11 in the ash box 9, and at the same time start the vibrator 4 to make the left side of the boiler body 1 vibrate again. Since the coal ash is relatively fine, it will be more refined under the action of vibration and can quickly fall from the sieve holes of the first sieve plate 12 and the second sieve plate 13.
[0027] Specifically, a collecting box 11 is mounted on the right side of the inner wall of the ash box 9, and a fixing plate 22 is fixedly connected to the middle part of the inner wall of the ash box 9; a negative pressure fan 14 is fixedly connected to the middle part of the inner wall of the fixing plate 22; a plurality of dust filter plates 10 are mounted on the left inner wall of the front end of the ash box 9; the coal slag will fall into the collecting box 11, and a large amount of coal ash will float in the collecting box 11; at this time, the negative pressure fan 14 is started, and a negative pressure is generated at its right end, which sucks the coal ash in the collecting box 11 into the left inner cavity of the collecting box 11; the coal ash passes through the dust filter plate 10 and adheres to the filter screen on its inner wall; after the coal ash is processed, the collecting box 11 and the dust filter plate 10 are taken out directly from the ash box 9, and the coal slag and coal ash are cleaned.
[0028] Working principle: First, remove the cover plate 21 together with the locking plate 20 from the top of the processing bucket 2, and then use the conveying mechanism to throw the coal into the processing bucket 2, and at the same time start the motors 19 on both sides, so that the transmission rod 17 drives the corresponding crushing roller 18 to rotate toward the opposite side to crush the coal, making it more delicate and burning more fully. The crushed coal ash first falls on the first screen plate 12, and then start the vibrator 4 to make the left side of the boiler body 1 vibrate. Through the conduction effect of vibration, the first screen plate 12 is shaken to screen the coal. The coal with smaller particles will fall to the top of the second screen plate 13 and continue to shake and screen. The finer coal particles will fall to the top of the baffle 5, and then turn off the vibrator 4, and then cover the top of the processing bucket 2 with the cover plate 21 again, and start the burner 3 on the left side, so that the burner 3 burns the coal in each layer, and the heat generated by the combustion will be transmitted to the boiler through the isolation cover 16. The medium in the inner cavity on the right side of the furnace body 1 is heated to generate steam for heating or industrial power generation. After the combustion is completed, the hydraulic rod 8 is started to push the connecting plate 7 to move to the left, and at the same time, the connecting rod 6 is driven to pull the baffle 5 out of the boiler body 1, so that the coal slag after combustion falls from the boiler body 1 to the collection box 11 in the ash box 9. At the same time, the vibrator 4 is started to make the left side of the boiler body 1 vibrate again, so that the coal slag quickly falls into the collection box 11 from the sieve holes of the first sieve plate 12 and the second sieve plate 13, and the coal slag will have a large amount of coal ash floating in the collection box 11. At this time, the negative pressure fan 14 is started, and its right end generates negative pressure, which sucks the coal ash in the collection box 11 into the left inner cavity of the collection box 11. The coal ash passes through the dust filter plate 10 and adheres to the filter screen on its inner wall. After the coal ash is processed, the collection box 11 and the dust filter plate 10 are directly taken out from the ash box 9 to clean the coal slag and coal ash.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
