[0002] To reduce energy consumption and lower costs in chemical production, and to replace the energy-intensive process of "electrolysis of water to produce hydrogen," an advanced methanol vapor reforming-pressure swing adsorption technology is used to produce pure hydrogen and a CO2-rich mixed gas. After further post-processing, hydrogen and carbon dioxide can be obtained simultaneously.

[0003] According to the utility model patent application CN220165828U, a raw material proportioning device for methanol-to-hydrogen production is disclosed.

It is also relatively large in size, which makes it difficult to operate and the hydrogen production time is relatively long. Therefore, we provide an automatic raw material proportioning and mixing device for methanol-to-hydrogen production to solve the above problems. Utility Model Content

[0014] 1. This utility model achieves a compact layout of the device through the ingenious design of the plate body, support columns and stabilizing plate, effectively reducing the overall volume and making the operation more flexible and convenient.

[0016] 3. This utility model further optimizes the hydrogen production process through the design of the mixing mechanism, improving the efficiency of hydrogen production.

Overall, the design of this mixing mechanism simplifies the hydrogen production steps, reduces the difficulty of operation, and provides users with a more efficient and faster hydrogen production experience.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] This embodiment provides an automatic proportioning and mixing device for raw materials in methanol-to-hydrogen production. This device is used for the proportioning of raw materials in methanol-to-hydrogen production. By setting a proportioning mechanism 4, the accuracy and efficiency of the raw material proportioning can be significantly improved.

[0024] See Figs. 1-4 An automatic proportioning and mixing device for methanol-to-hydrogen feedstock includes a plate body 1. Two support columns 2 are fixedly installed on the upper surface of the plate body 1. A stabilizing plate 3 is fixedly installed on the upper surface of the two support columns 2. A proportioning mechanism 4 is provided on the outer side of the stabilizing plate 3. The proportioning mechanism 4 includes three connecting columns 401. The back of each connecting column 401 is fixedly connected to the front of the stabilizing plate 3. A proportioning container 402 is fixedly installed at the end of each connecting column 401 away from the stabilizing plate 3. Two sets of bases 9 are provided below the plate body 1. The upper surface of each set of bases 9 is fixedly connected to the bottom surface of the plate body 1. The setting of the two sets of bases 9 enhances the stability of the plate body 1, provides solid support for the entire device, ensures the smooth operation of the device, and improves safety and service life.

[0025] Each proportioning container 402 has an input pipe 408 fixedly connected to its upper surface. Each input pipe 408 has a feed pump 407 fixedly connected to its end away from the proportioning container 402. Each proportioning container 402 has an output pipe 403 of different heights fixedly connected to its outer surface. The outer surfaces of the two support columns 2 are jointly fixedly installed with a reinforcing plate 5. The bottom surface of the reinforcing plate 5 is fixedly connected to the upper surface of the plate body 1. The installation of the reinforcing plate 5 on the outer surface of the support column 2 further enhances the strength and stability of the support column 2, effectively disperses the pressure of the upper structure, protects the plate body 1, and extends the overall service life of the device.

[0026] A heating device 404 is fixedly installed on the upper surface of the plate 1. A cross plate 409 is fixedly installed on the inner wall of each proportioning container 402. A telescopic spring 410 is fixedly installed on the bottom surface of each cross plate 409. A baffle plate 411 is fixedly installed at the bottom end of each telescopic spring 410. A support rod 8 is fixedly installed on the bottom surface of each proportioning container 402. The bottom end of each support rod 8 is fixedly connected to the upper surface of the plate 1. The support rod 8 on the bottom surface of the proportioning container 402 provides additional support force, ensuring the stability of the proportioning container 402 during operation, avoiding proportioning errors caused by container shaking, and improving proportioning accuracy.

[0027] Each baffle plate 411 has a contact block 413 fixedly installed on its bottom surface. Each mixing container 402 has a pressure sensor 412 fixedly installed on its inner bottom wall. Three controllers 406 are fixedly installed on the upper surface of the stabilizing plate 3. Each controller 406 is electrically connected to the feed pump 407 via a wire. Each pressure sensor 412 is electrically connected to the controller 406 via a wire. The output end of the heating device 404 is fixedly connected to two exhaust pipes 405. A motor mount 7 is fixedly installed on the outer surface of the motor 601. The right side of the motor mount 7 is fixedly connected to the left side of the heating device 404. The installation of the motor mount 7 on the outer surface of the motor 601 increases the installation stability of the motor 601. The fixed connection between the motor mount 7 and the heating device 404 optimizes the spatial layout, facilitates maintenance and replacement, and improves the reliability and maintenance efficiency of the device.

[0028] A mixing mechanism 6 is provided above the plate 1. The mixing mechanism 6 includes a motor 601. The outer surface of the motor 601 is fixedly connected to the outer surface of the heating device 404. A rotating shaft 602 is fixedly installed at the power output end of the motor 601. The end of the rotating shaft 602 away from the motor 601 passes through the heating device 404 and extends into the interior of the heating device 404. Several stirring blades 603 are fixedly installed on the outer surface of the rotating shaft 602. A stabilizing block 10 is fixedly installed on the outer surface of each exhaust pipe 405. The back of each stabilizing block 10 is fixedly connected to the front of the heating device 404. The fixing of the stabilizing block 10 on the outer surface of the exhaust pipe 405 enhances the stability of the exhaust pipe 405, prevents the exhaust pipe 405 from shifting during use, ensures smooth exhaust gas discharge, and improves the safety and emission efficiency of the device.

[0029] Working principle: When in use, first place the automatic proportioning and mixing device for methanol to hydrogen raw materials on a stable ground. The two sets of bases 9 under the plate 1 provide additional stability. After the device is started, the feed pump 407 starts to work and transports the methanol raw material to the proportioning container 402 through the input pipe 408. The upper surface of each proportioning container 402 is connected to the input pipe 408 to ensure that the raw material is evenly distributed.

[0030] The cross plate 409, telescopic spring 410, baffle plate 411 and abutment block 413 on the inner wall of the mixing container 402 work together to prevent the raw materials from being blocked during the conveying process and to ensure the smooth flow of the raw materials. The pressure sensor 412 monitors the pressure changes in the container in real time and transmits the data to the controller 406. The controller 406 adjusts the flow rate of the feed pump 407 precisely according to the feedback from the pressure sensor 412 to realize the automatic mixing of raw materials.

[0031] The proportioned raw materials flow into the heating device 404 through output pipes 403 at different heights. The heating device 404 heats the raw materials, promoting the decomposition of methanol and producing hydrogen. At the same time, the motor 601 starts, driving the rotating shaft 602 to rotate. The stirring blades 603 on the rotating shaft 602 stir the raw materials in the heating device 404, ensuring that the raw materials are heated evenly and the reaction is complete. Afterwards, the exhaust pipe 405 connected to the output end of the heating device 404 discharges the waste gas, thus realizing the automatic proportioning and mixing of raw materials for methanol to hydrogen production, simplifying the hydrogen production process, improving hydrogen production efficiency, and requiring operators to only monitor the operating status of the device without frequent manual intervention, greatly reducing the difficulty of operation and labor intensity.
