[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-7 As shown, this utility model provides a technical solution:

[0025] A combustion device with a coal cracking hydrogen production reaction chamber includes a combustion device body 1. A feeding pipe 2 is connected to one side of the combustion device body 1. A first feed inlet 3 and a second feed inlet 4 are connected to the feeding pipe 2. A discharge component is provided on the first feed inlet 3. A hopper 5 is connected to the top of the first feed inlet 3. A stirring component is provided on the hopper 5. A storage bin 6 is connected to the top of the second feed inlet 4. A rotating shaft 7 is rotatably connected inside the feeding pipe 2. A spiral blade 8 and a first bevel gear 9 are coaxially fixedly connected to the rotating shaft 7. A protective cover 10 is fixedly connected to the end of the feeding pipe 2 away from the combustion device body 1. A first servo motor 11 is fixedly connected to one side of the protective cover 10. The output end of the first servo motor 11 passes through the protective cover 10 and is rotatably connected to it. The output end of the first servo motor 11 is coaxially fixedly connected to the rotating shaft 7 through a coupling. A transmission component is provided on the protective cover 10.

[0026] Specifically, the storage bin 6 contains pulverized coal, and the hopper 5 contains dry powder catalyst. The pulverized coal falls into the feeding pipe 2 through the second feed inlet 4, and the dry powder catalyst falls into the feeding pipe 2 through the first feed inlet 3. The first servo motor 11 is started, and the output of the first servo motor 11 can drive the spiral blade 8 to rotate through the rotating shaft 7. The spiral blade 8 has both conveying and stirring functions. The catalyst and pulverized coal are fully mixed during the conveying process. The discharge component can adjust the size of the discharge opening on the first feed inlet 3, so that the amount of catalyst added can be adjusted according to the speed at which the spiral blade 8 conveys the pulverized coal. When the spiral blade 8 rotates faster, the pulverized coal conveying speed increases, and the discharge opening on the first feed inlet 3 can be enlarged, increasing the amount of catalyst added per unit time, so that the mixing ratio of catalyst and pulverized coal is kept within a suitable range. The rotating shaft 7 drives the first bevel gear 9 to rotate together, and the first bevel gear 9 drives the transmission component to work. The transmission component drives the stirring component to work. The stirring component can slowly stir the dry powder catalyst in the hopper 5, so that the catalyst remains in a loose state, avoids catalyst clumping, and ensures that the catalyst is continuously and smoothly added.

[0027] The feeding assembly includes a housing 12 and a pair of opening and closing plates 13. The housing 12 is fixedly connected to the outer periphery of the first feed port 3. The pair of opening and closing plates 13 are slidably connected to the first feed port 3. A second servo motor 14 is fixedly connected to the top of the housing 12. The output end of the second servo motor 14 passes through the housing 12 and is rotatably connected to it. A connecting strip 15 is fixedly connected to the opposite side of the pair of opening and closing plates 13. A toothed plate 16 is fixedly connected to one side of the connecting strip 15. A gear 17 is coaxially fixedly connected to the output end of the second servo motor 14. The gear 17 and the toothed plate 16 mesh with each other.

[0028] Specifically, the second servo motor 14 is started, and the output of the second servo motor 14 drives the gear 17 to rotate. The gear 17 drives a pair of opening and closing plates 13 to move in opposite directions through a pair of toothed plates 16 and corresponding connecting bars 15. The dry powder catalyst can fall through the gap between the pair of opening and closing plates 13.

[0029] The mixing assembly includes a mixing shaft 18, which is rotatably connected to the hopper 5. A pair of mixing blades 19 are coaxially fixedly connected to the mixing shaft 18, and a first pulley 20 is coaxially fixedly connected to one end of the mixing shaft 18.

[0031] The transmission assembly includes a transmission shaft 21, which is rotatably connected to the protective cover 10. One end of the transmission shaft 21 is coaxially fixedly connected to a second bevel gear 22, which meshes with a first bevel gear 9. The other end of the transmission shaft 21 is coaxially fixedly connected to a second pulley 23, and a belt is sleeved between the second pulley 23 and the first pulley 20.

[0032] Specifically, the first bevel gear 9 drives the transmission shaft 21 to rotate through the second bevel gear 22, the second pulley 23 rotates together with the transmission shaft 21, and the second pulley 23 drives the first pulley 20 to rotate through the belt;

[0034] Specifically, the dry powder catalyst can be added to the hopper 5 through the feeding port, the support feet are used to support the stable storage bin 6, and the support column is used to support the stable combustion equipment body 1.

[0035] The working principle of this utility model is as follows:

[0036] The storage bin 6 contains pulverized coal, and the hopper 5 contains dry powder catalyst. The pulverized coal falls into the feeding pipe 2 through the second feed port 4, and the dry powder catalyst falls into the feeding pipe 2 through the first feed port 3. The first servo motor 11 is started, and the output end of the first servo motor 11 can drive the spiral blade 8 to rotate through the rotating shaft 7. The spiral blade 8 has both conveying and stirring functions, and the catalyst and pulverized coal are fully mixed during the conveying process.

[0037] The second servo motor 14 is started, and the output of the second servo motor 14 drives the gear 17 to rotate. The gear 17 drives a pair of opening and closing plates 13 to move in opposite directions through a pair of toothed plates 16 and a corresponding connecting bar 15. The dry powder catalyst can fall through the gap between the pair of opening and closing plates 13. By controlling the size of the gap between the pair of opening and closing plates 13, the size of the material drop opening on the first feed port 3 can be adjusted, so that the amount of catalyst added can be adjusted according to the speed of coal powder conveying by the spiral blade 8. When the spiral blade 8 rotates faster, the coal powder conveying speed increases, and the material drop opening on the first feed port 3 can be enlarged, increasing the amount of catalyst added per unit time, so that the mixing ratio of catalyst and coal powder is kept within a suitable range.

[0038] The rotating shaft 7 drives the first bevel gear 9 to rotate together. The first bevel gear 9 drives the transmission shaft 21 to rotate through the second bevel gear 22. The second pulley 23 rotates together with the transmission shaft 21. The second pulley 23 drives the first pulley 20 to rotate through the belt. The first pulley 20 drives a pair of stirring blades 19 to rotate through the stirring shaft 18, so as to slowly stir the dry powder catalyst in the hopper 5, keep the catalyst in a loose state, avoid catalyst clumping, and ensure the continuous and smooth addition of catalyst.
