Aerospace Hydrogen Energy Cangzhou Gas has filed a patent for a coal powder feeding device used in the production of high-purity syngas, aiming to address the issue in existing technologies where manual pouring of coal powder into the feeding hopper is required, resulting in low efficiency. According to a report from Finance World dated August 15, 2025, the Intellectual Property Office records show that Aerospace Hydrogen Energy Cangzhou Gas Co., Ltd. has applied for a patent titled “A Coal Powder Feeding Device for the Production of High-Purity Syngas”, with the publication number CN120482734A; the application was submitted in June 2025. The patent abstract indicates that this disclosure relates to the technical field of coal powder feeding devices. An embodiment of this disclosure provides a coal powder feeding device for producing high-purity syngas, which includes a bottom plate, as well as a material conveying fan, a feeding pipe, a material suction component, a transmission housing, support frames, gear plates, an adjustment mechanism, driven gears, and twisting components. The material conveying fan is installed on the upper side of the bottom plate via a support platform; the output end of the material conveying fan is connected to the feeding pipe, while its input end is connected to a feed pipe. A material suction component is inserted into the feed pipe and is used to suck up coal powder from the ground. The transmission housing is mounted on the outside of the material suction component via a first rotating shaft. Two support frames are installed on the upper side of the bottom plate, and a gear plate is vertically mounted on one of these support frames. Through this technical solution, the problem existing in prior art, where manual pouring of coal powder into the feeding hopper was required, resulting in low work efficiency, is addressed.
