[0017] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 9 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0018] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0019] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0020] A honeycomb-shaped high-temperature cracking hydrogen production device includes a furnace body 1, inside which a heating block 2 is installed. A heating source for heating the heating block 2 is located at the bottom of the furnace body 1. In this embodiment, the heating source is an electric heating rod. During use, electricity is applied to heat the heating rod, which in turn heats the heating block 2. Multiple evenly distributed heating holes 3 are formed inside the heating block 2. The cross-section of each heating hole 3 is hexagonal, and the hexagonal holes are arranged in a honeycomb pattern to increase space utilization. During use, water is poured into the furnace body 1, entering the heating holes 3 and increasing the contact area between the heating block 2 and the water, thereby improving the hydrogen production efficiency. A catalytic layer is provided inside each heating hole 3. The catalytic layer is made of a catalyst. During high-temperature cracking hydrogen production, water is used as a raw material, and hydrogen is produced under high-temperature conditions (around 1500℃) and the action of the catalyst.

[0021] The furnace body 1 is provided with an air outlet 5 and a water inlet 6 on the top. In use, water enters the furnace body 1 through the water inlet 6, and the gas heated at high temperature exits from the air outlet 5. The air outlet 5 is connected to a gas collection device. After the gas collection device collects the gas, hydrogen is separated through subsequent processing. A pipe is connected to the water inlet 6, and a filter structure is connected to the pipe.

[0022] The heating block 2 is made of alumina ceramic material, and the alumina ceramic material and structure can ensure that the structure maintains its strength and stability at a high temperature of 1500℃.

[0023] The filter structure includes a filter housing 7, with an inlet hole 8 and an outlet hole 9 at both ends of the filter housing 7. Both the inlet hole 8 and the outlet hole 9 are connected to the pipeline. A filter screen 10 is installed inside the filter housing 7, and the filter screen 10 is installed at the inlet hole 8. In use, water flows into the filter housing 7 through the pipeline from the inlet hole 8. When the water flows into the filter housing 7 from the inlet hole 8, it is filtered by the filter screen 10, which isolates large particles of impurities outside the filter housing 7 and prevents them from entering the furnace body 1 through the filter housing 7.

[0024] The filter housing 7 is circular, and a drive disk 11 is rotatably connected inside the filter housing 7. The filter screen 10 is fixedly connected to the drive disk 11 and is arc-shaped. The filter housing 7 has two cleaning water holes 12, which are respectively distributed above and below the water inlet 8. The filter screen 10 has blocking pads 13 fixedly connected to both the upper and lower ends to block the cleaning water holes 12. When in use, rotate the drive disc 11 counterclockwise to make the filter screen 10 rotate downward. The blocking pad 13 at the upper end of the filter screen 10 blocks the upper cleaning water hole 12. Water enters from the water inlet 8 and flows out from the water outlet 9. At the same time, the water flow is separated and flows out through the lower cleaning water hole 12, thus cleaning the impurities on the filter screen 10. Rotating the drive disc 11 clockwise causes the filter screen 10 to rotate upwards. The shielding pad 13 at the lower end of the filter screen 10 blocks the cleaning water hole 12 at the lower end. Water enters from the inlet hole 8 and flows out from the outlet hole 9. At the same time, the water is separated and flows out through the upper cleaning water hole 12, cleaning the impurities on the filter screen 10. The cleaned water flows out through the cleaning water hole 12 to the collection device.

[0025] The filter housing 7 is equipped with a drive device for controlling the rotation of the drive disc 11. The drive device includes a drive mounting plate 14 fixedly connected to one side of the filter housing 7. Two drive water tanks 15 are slidably connected to the drive mounting plate 14. The drive mounting plate 14 has a limiting groove. A limiting slider that cooperates with the limiting groove is fixedly connected to the drive water tank 15. A push shaft 16 is fixedly connected to the side of each drive water tank 15 near the drive mounting plate 14. A drive shaft 16 is fixedly connected to the side of the drive disc 11 near the drive mounting plate 14. 7. Rotating the drive shaft 17 drives the drive disc 11 to rotate. A swing rod 18 is fixedly connected to the drive shaft 17. The rotation of the swing rod 18 drives the drive disc 11 to rotate. Both ends of the swing rod 18 are slidably connected to the two push shafts 16 respectively. Both ends of the swing rod 18 are provided with sliding grooves, and the push shafts 16 are slidably connected inside the sliding grooves. When the swing rod 18 swings, it drives one of the drive water tanks 15 to swing upward and the other drive water tank 15 to swing downward, thus alternately swinging the drive disc 11 to rotate up and down. The two cleaning water holes 12 are respectively connected to guide tubes. Two flow pipes 19 are respectively located above the two drive water tanks 15. Two magnets 20 are fixedly connected to the bottom of the drive mounting plate 14, and the two magnets 20 are respectively located below the two drive water tanks 15. Each drive water tank 15 has a fixedly connected iron plate 21 that matches the magnet 20. During use, the shielding pad 13 at the upper end of the filter screen 10 blocks the upper cleaning water hole 12, and water flows out through the lower cleaning water hole 12, simultaneously cleaning impurities on the filter screen 10. The water that has been cleaned flows through the flow pipes 19 into the drive water tank 15 located at a higher position. 5. The bottom iron plate 21 of the driving water tank 15 located at the lower position contacts the magnet 20. Under the action of the iron plate 21 and the magnet 20, the driving water tank 15 at the lower end is attracted here until the driving water tank 15 located at the higher position is filled with water. After the weight of the driving water tank 15 is greater than the attraction force of the iron plate 21 and the magnet 20, the driving water tank 15 filled with water slides downward. Under the action of the swing rod 18, the driving water tank 15 at the lower position slides upward. At the same time, the swing rod 18 drives the driving disc 11 to rotate, causing the filter screen 10 to rotate upward. The blocking pad 13 at the lower end of the filter screen 10 blocks the cleaning water hole 12 at the lower end. The shielding pad 13 at the lower end of the filter screen 10 blocks the cleaning water hole 12 at the lower end. Water flows out through the upper cleaning water hole 12, cleaning impurities on the filter screen 10. The cleaned water flows through the cleaning water hole 12 into the water guide pipe 19, and then flows into the drive water tank 15 located at the upper position. After the drive water tank 15 at the upper position is full of water, it slides downward. Under the action of the swing rod 18, it drives the drive water tank 15 at the lower position to slide upward. At the same time, the swing rod 18 drives the drive disc 11 to rotate, causing the filter screen 10 to rotate downward. The shielding pad 13 at the upper end of the filter screen 10 blocks the upper cleaning water hole 12. This process is repeated continuously to clean the filter screen 10, thereby preventing the water inlet hole 8 from becoming blocked.

[0026] The bottom of the drive water tank 15 is equipped with a water discharge structure, which includes a water outlet 22 at the bottom of the drive water tank 15. A clamping shaft 23 is slidably connected above the water outlet 22. A tension spring 24 is connected between the clamping shaft 23 and the drive water tank 15. In the initial position, under the action of the tension spring 24, the clamping shaft 23 is pulled to slide closer to the water outlet 22, so that the clamping shaft 23 blocks the water outlet 22, thereby preventing water from leaking out of the drive water tank 15. The bottom of the drive mounting plate 14 is fixedly connected to a control drain pipe 25, which is located directly below the water outlet 22. The control drain pipe 25 has multiple guide holes 26. When the drive water tank 15 slides down to its limit position, the control drain pipe 25 is inserted into the drain outlet 22. The drain outlet 22 contacts the clamping shaft 23, pushing the clamping shaft 23 away from the drain outlet 22, so that water flows into the control drain pipe 25 through the guide hole 26. The control drain pipe 25 is connected to the wastewater collection device through a pipe to collect and treat the wastewater for reuse, thereby realizing the discharge of water from the drive water tank 15 located at the lower end.

[0027] A rubber sealing block 27 is fixedly connected to one end of the top clamping shaft 23 near the drain outlet 22. The rubber sealing block 27 is used to seal the drain outlet 22.

[0028] An extension pipe 28 is fixedly connected inside the furnace body 1. The extension pipe 28 is connected to the water inlet 6. A water distribution valve 29 is rotatably connected to the bottom of the extension pipe 28. Multiple water outlet plates 30 are fixedly connected to the water distribution valve 29. The cross-section of the water outlet plate 30 is set as a right-angled trapezoid. Multiple spray nozzles 31 are opened on the inclined surface of the water outlet plate 30. Water flows out through the water outlet hole 9 and flows into the extension pipe 28 through the pipe. The water inside the extension pipe 28 enters the water distribution valve 29 and then enters the water outlet plate 30. It is then sprayed evenly from the spray nozzles 31. The spray nozzles 31 are located on the inclined surface of the water outlet plate 30. When water is sprayed from the spray nozzles 31, the reaction force pushes the water distribution valve 29 to rotate on the extension pipe 28, so that the water is evenly sprayed onto the heated block 2 and flows into the heating hole 3, thereby improving the efficiency of hydrogen production.

[0029] The heating block 2 is detachably connected to the bottom of the furnace body 1. The bottom of the furnace body 1 is provided with an installation groove 32. The bottom of the heating block 2 is fixedly connected with a mating block 33 that cooperates with the installation groove 32. When it is necessary to replace or maintain the heating block 2, the heating block 2 is removed from the bottom of the furnace body 1, and the mating block 33 of the replaced heating block 2 is inserted into the installation groove 32, so that it is easy to replace and use, and improves the efficiency of replacement or maintenance.

[0030] In use, water is introduced into the inlet hole 8 through a pipe. The water is filtered through the filter screen 10 to isolate large particles of impurities outside the filter housing 7, preventing them from entering the furnace body 1 through the filter housing 7. The water flows into the extension pipe 28 through the outlet hole 9. The water inside the extension pipe 28 enters the water distribution valve 29 and then enters the water outlet plate 30. It is then sprayed evenly from the spray nozzle 31, which is located on the inclined surface of the water outlet plate 30. When the water is sprayed from the spray nozzle 31, the reaction force pushes the water distribution valve 29 to rotate on the extension pipe 28, so that the water is evenly sprayed onto the heated block 2 and flows into the heating hole 3, thereby improving the efficiency of hydrogen production. In the initial state, the shielding pad 13 at the upper end of the filter screen 10 blocks the upper cleaning water hole 12, and the water flows out through the lower cleaning water hole 12, cleaning the impurities on the filter screen 10 at the same time. The water that has been cleaned of impurities flows into the drive water tank 15 located at the upper position through the guide pipe 19. The iron plate 21 at the bottom of the drive water tank 15 located at the lower position contacts the magnet 20. Under the action of the iron plate 21 and the magnet 20, the drive water tank 15 at the lower position is attracted here until the drive water tank 15 located at the upper position is filled with water. After the weight of the drive water tank 15 is greater than the attraction force of the iron plate 21 and the magnet 20, the drive water tank 15 filled with water slides downward. Under the action of the swing rod 18, the drive water tank 15 at the lower position slides upward. At the same time, the swing rod 18 drives the drive disc 11 to rotate, causing the filter screen 10 to rotate upward. The shielding pad 13 at the lower end of the filter screen 10 blocks the lower cleaning water hole 12. The shielding pad 13 at the lower end of the filter screen 10 blocks the cleaning water hole 12 at the lower end. Water flows out through the upper cleaning water hole 12, cleaning impurities on the filter screen 10. The cleaned water flows through the cleaning water hole 12 into the water guide pipe 19, and then flows into the drive water tank 15 located at the upper position. After the drive water tank 15 at the upper position is full of water, it slides downward. Under the action of the swing rod 18, it drives the drive water tank 15 at the lower position to slide upward. At the same time, the swing rod 18 drives the drive disc 11 to rotate, causing the filter screen 10 to rotate downward. The shielding pad 13 at the upper end of the filter screen 10 blocks the upper cleaning water hole 12. This process is repeated continuously to clean the filter screen 10, thereby preventing the water inlet hole 8 from becoming blocked.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
