Description

Technical Field

[0001] This utility model relates to the field of methanol-to-hydrogen technology, and more specifically, to a methanol-to-hydrogen raw material conveying device. Background Technology

[0002] In the methanol-to-hydrogen production process, the raw material transportation stage plays a crucial role in the quality of the final product and production efficiency. However, in actual transportation, various impurities often adhere to the raw materials. These impurities may originate from multiple stages such as mining, storage, and transportation. When raw materials containing impurities are directly introduced into the mixing tank, the mixing effect is severely affected. The presence of impurities leads to uneven mixing of the raw materials, resulting in insufficient subsequent methanol-to-hydrogen reaction, reducing reaction efficiency. Moreover, impurities may adversely affect the catalyst in the hydrogen production process, such as poisoning and deactivating the catalyst, thereby greatly reducing the later preparation effect, increasing production costs, and lowering product quality. Therefore, we propose a methanol-to-hydrogen raw material transportation device to solve the above problems. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown in the figure, this utility model embodiment proposes a methanol-to-hydrogen raw material conveying device, including a mixing tank 1. An auxiliary trough 6 is provided at the upper end of the mixing tank 1. Feed pipes 2 are respectively installed through both sides of the upper end of the auxiliary trough 6. A filter mechanism 3 is respectively installed at the upper end of the feed pipes 2. A mixing trough 8 is provided at the lower end of the mixing tank 1. A connecting hole 9 is provided through the mixing trough 8 and the auxiliary trough 6. A drain pipe 5 is installed through the lower end of the mixing trough 8. The filter mechanism 3 includes a storage box 301. Each storage box 301 is installed at the upper end of the feed pipe 2. A groove 302 is provided inside each storage box 301. An extension pipe 303 is respectively installed through the lower end of the groove 302. The lower end of the extension pipe 303 is respectively connected to the feed pipe 2. A connecting pipe is installed through the upper end of the groove 302. A filter cylinder 305 is movably installed inside the tube 311 and the groove 302. The lower end of the filter cylinder 305 is engaged with the extension tube 303. A sealing frame 310 is movably installed on the outer side of the filter cylinder 305. A limiting plate 307 is installed on the lower outer side of the filter cylinder 305. A spring 308 is installed on the outer side of the filter cylinder 305 between the limiting plate 307 and the sealing frame 310. The upper and lower ends of the spring 308 are connected to the limiting plate 307 and the sealing frame 310, respectively. The upper end and the lower inner end of the sealing frame 310 are respectively in contact with the upper surface of the groove 302 and the upper end of the filter cylinder 305. The lower end of the connecting tube 311 is located inside the sealing frame 310 and overlaps with the filter cylinder 305 vertically. Several filter layers 309 are placed inside the filter cylinder 305.

[0023] like Figures 4 to 6As shown, in another embodiment of this utility model, a plurality of guide inclined plates 7 are installed inside the auxiliary trough 6, and the guide inclined plates 7 are arranged alternately and parallel to each other. A motor 4 is installed at the upper end of the mixing box 1. A rotating shaft 10 is movably installed between the auxiliary trough 6, the connecting hole 9 and the mixing trough 8. The shaft 10 is located inside the auxiliary trough 6 and is movably installed inside the guide inclined plates 7. The output end of the motor 4 is movably installed through the upper end of the mixing box 1 and connected to the rotating shaft 10. A plurality of mixing plates 11 are installed on the outside of the shaft 10 inside the mixing trough 8. The mixing plates 11 are movably located inside the mixing trough 8. A valve is installed at the lower end of the drain pipe 5. The upper end of the extension pipe 303 is provided with a locking groove 304. The lower end of the filter cylinder 305 is locked and installed inside the locking groove 304. A plurality of positioning rods 306 are installed on the lower surface of the filter cylinder 305. The positioning rods 306 are locked and installed inside the lower end of the locking groove 304. Sealing doors 312 are installed on the opposite sides of the grooves 302 through hinges.

[0024] The raw materials enter the filter cylinder 305 through the connecting pipe 311. The filter layer 309 in the filter cylinder 305 then begins to filter the raw materials, filtering and isolating impurities that have adhered to the raw materials during storage and transportation. After filtration, the raw materials enter the auxiliary tank 6 through the extension pipe 303 and the feed pipe 2. The raw materials then flow along several guide inclined plates 7, which also initially mix the raw materials. The initially mixed raw materials then enter the mixing tank 8 through the connecting hole 9. At the same time, the motor 4 drives the rotating shaft 10 and the mixing plate 11 to rotate, allowing the mixing plate 11 to further stir and mix the raw materials, improving the mixing efficiency and effect. Finally, the mixed raw materials are discharged through the drain pipe 5 and enter the subsequent processing steps of methanol to hydrogen production.

[0025] The positioning rod 306 is used to position the filter cartridge 305, ensuring that the filter cartridge 305 remains stable during use. Simultaneously, in conjunction with the spring 308 pushing the sealing frame 310, the sealing frame 310 fits against the inner upper surface of the groove 302 and the upper end of the filter cartridge 305, thus achieving the installation of the filter cartridge 305. This maintains the sealing performance inside the filter cartridge 305. Furthermore, when the filter cartridge 305 needs to be removed later, the user simply pulls the sealing frame 310 downwards, causing it to compress the spring 308, and then pulls the filter cartridge 305 upwards. This allows the filter cartridge 305 to move the positioning rod 306 out of the locking groove 304, completing the removal process more conveniently.

[0026] Working principle of a methanol-to-hydrogen raw material conveying device:

[0027] In use, the raw materials first enter the filter cylinder 305 through the connecting pipe 311. Then, the filter layer 309 inside the filter cylinder 305 begins to filter the raw materials, filtering and isolating impurities that have adhered to the raw materials during storage and transportation. After filtration, the raw materials enter the auxiliary tank 6 through the extension pipe 303 and the feed pipe 2. The raw materials then flow along several guide inclined plates 7, which also initially mix the raw materials. The initially mixed raw materials then enter the mixing tank 8 through the connecting hole 9. At the same time, the motor 4 drives the rotating shaft 10 and the mixing plate 11 to rotate, allowing the mixing plate 11 to further stir and mix the raw materials, improving the mixing efficiency and effect. Finally, the mixed raw materials are discharged through the drain pipe 5 and enter the subsequent processing steps of methanol to hydrogen production.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
