Description

Technical Field

[0002] A hydrogen generator is a device or system used to produce hydrogen, usually by extracting hydrogen from water or other hydrogen source substances through chemical reactions. Hydrogen is an important industrial raw material and an important component of the clean energy sector. It is produced by reacting natural gas or other hydrocarbons with steam at high temperatures to produce hydrogen and carbon dioxide.

[0003] The catalyst placed in the hydrogen production device is usually a specific substance or mixture used to promote the hydrogen generation reaction. These catalysts usually exist in the form of powder or particles, and need to have specific chemical properties and structural characteristics to achieve efficient reaction performance. When placing the catalyst, the operator needs to rely on long-term experience or simple manual adjustment to control the amount of catalyst placed, resulting in the lack of precise control of the amount of catalyst placed, resulting in uneven distribution of the catalyst in the reactor. Some areas may have excessive amounts, while other areas may have insufficient amounts. The uneven distribution will affect the efficiency and product of the reaction. When the catalyst particles are placed through the storage device, the catalyst particles may accumulate or agglomerate in the storage device due to their own gravity or vibration and bumps during transportation. This may cause blockage in the storage device, affecting the smooth placement of the catalyst, resulting in frequent shutdowns and cleaning processes that will increase the maintenance cost of the device, and will also affect the stable operation and production efficiency of the hydrogen production device.

The support plate 201 and the first fixed plate 202 are internally fixedly connected with a guide plate 203. The guide plate 203 is fixed inside by the support plate 201 and the first fixed plate 202 to support and fix the guide plate 203. The support plate 201 is connected to an external device and a wall to fix and support the entire device. The guide plate 203 is internally slidably connected with a slider 204. The left side wall of the slider 204 is fixedly connected with a first fixed ring 205. The first fixed ring 205 is internally connected with a barrel 206. The slider 2 04 and the first fixed ring 205 slide inside the guide plate 203 to drive the barrel 206 to slide left and right. The bottom of the barrel 206 is rotatably connected to a bottom cover 207. The bottom wall of the barrel 206 is closed and opened by the bottom cover 207. When it is convenient to pour out the catalyst particles inside the barrel 206, the bottom wall of the support plate 201 is fixedly connected to an L-shaped support plate 208. The L-shaped support plate 208 is used to support and fix the bottom of the barrel 206 and the bottom cover 207.

A weight sensor 213 is arranged inside the L-shaped support plate 208. The upper side wall of the weight sensor 213 is arranged at the bottom of the bottom cover 207. By arranging the barrel 206 and the bottom cover 207 on the top of the weight sensor 213, the weight of the catalyst inside the barrel 206 is measured. When the weight reaches a certain level, the electric push rod 210 will drive the barrel 206 to slide out from the upper side wall of the L-shaped support plate 208. After sliding out, the bottom cover 207 at the bottom of the barrel 206 will automatically open to put the lubricant particles into the hydrogen production device.

The output end of the motor 7 is fixedly connected with a rotating shaft 9. The outer side of the rotating shaft 9 is fixedly connected with a second gear 10. The second gear 10 is meshed with the first gear 6. The second gear 10 is meshed with the first gear 6 through the second gear 10 on the outer side of the rotating shaft 9 on the output end of the motor 7, and drives the first gear 6 to rotate inside the storage cylinder 1 and the delivery tube 3.

[0032] like Figure 1 - Figure 8As shown, the first gear 6 is fixedly connected to a connecting ring 11 inside, and a support rod 12 is fixedly connected to the connecting ring 11 inside. When the first gear 6 rotates, it will drive the internal connecting ring 11 and the support rod 12 to rotate. The upper side wall of the support rod 12 is fixedly connected to a rotating rod 13, and the middle outer side of the rotating rod 13 is fixedly connected to a stirring rod 14. The rotating rod 13 on the support rod 12 is connected to the stirring rod 14, and the stirring rod 14 is driven to rotate by the support rod 12, and then the catalyst particles inside the storage cylinder 1 are stirred by the rotating stirring rod 14 and the support rod 12 to prevent the catalyst particles from being put into the storage cylinder 1. The inside of the storage tube 1 is clogged and the catalyst particles can be stuck together. A second fixing ring 15 is fixedly connected to the outer side of the top end of the rotating rod 13. The left and right sides of the second fixing ring 15 are fixedly connected to connecting rods 16. The other ends of the two connecting rods 16 are fixedly connected to scrapers 17.

[0033] It should be noted that the utility model is a catalyst delivery device for a hydrogen production device. First, the electric push rod 210, the motor 7 and the weight sensor 213 are connected to an external control terminal and a power source to supply power to the device.

[0034] First, when the catalyst particles are put into the storage barrel 1, the delivery pipe 3 is fixed to the bottom of the storage barrel 1 through the connecting block 5, so that the catalyst flows into the inside of the barrel 206 through the delivery pipe 3, and the motor 7 is fixed to the bottom wall of the delivery pipe 3 through the second fixing plate 8, and the second gear 10 on the rotating shaft 9 on the output end of the motor 7 is meshed with the first gear 6 at the top of the delivery pipe 3 and the bottom of the storage barrel 1 to drive the first gear 6 to rotate. When rotating, the connecting ring 11 inside the first gear 6 drives the support rod 12 inside the storage barrel 1. The rotating rod 13 is supported and fixed by the upper side wall of the support rod 12, and the stirring rod 14 on the outside of the rotating rod 13 is driven to rotate to stir the catalyst particles inside the storage tube 1 to prevent the catalyst particles from being blocked inside the storage tube 1 and affecting the smooth delivery of the catalyst. When rotating, the rotating rod 13 is connected to the scraper 17 through the connecting rod 16 on the outside of the second fixing ring 15, and drives the scraper 17 to rotate inside the storage tube 1 to prevent the catalyst and particles from sticking to the inner wall of the storage tube 1.

[0035] When the catalyst particles are put in, after the support plate 201 is fixed to the wall and the external device by bolts, the catalyst inside the storage cylinder 1 will flow into the interior of the barrel 206 through the conveying pipe 3 at the bottom. When the barrel 206 reaches a certain weight, the data will be transmitted through the weight sensor 213 inside the L-shaped support plate 208. The telescopic rod 211 on the telescopic end of the electric push rod 210 will be connected to the barrel 206 through the adapter plate 212 to drive the first fixing ring 205 and the slider 204 on the outer side of the top of the barrel 206 to slide inside the guide plate 203 to drive the barrel 206 to leave the L-shaped support plate 208. After leaving the L-shaped support plate 208, the bottom cover 207 on the bottom of the barrel 206 will automatically open to put the catalyst particles inside the barrel 206 into the hydrogen production device.
