[0002] China has abundant coal resources, and direct combustion of coal is not only low in efficiency, but also causes serious pollution to the environment. Fischer-Tropsch synthesis reaction is a process of converting coal into liquid fuel or high-quality chemicals, and is one of the important ways for clean and efficient conversion and utilization of coal; when cobalt-based Fischer-Tropsch synthesis catalyst is prepared, inorganic salts containing cobalt, metal oxides, photosensitive resins, dispersants, anhydrous ethanol, deionized water and other raw materials are mixed and stirred uniformly. Chinese patent CN118267957A discloses a catalyst raw material solid-liquid mixing equipment, which comprises a supporting unit and a reaction unit installed on the surface. The supporting unit comprises a supporting table, and the reaction unit comprises a reaction tank and a sealing cover. The reaction tank is connected to the surface of the supporting table, and the inside of the reaction tank is provided with a driving stirring unit, a uniform material scattering unit and a discharging unit. The top plate moves upward synchronously, thereby lifting the catalyst inside the raw material tank, which facilitates the slow scattering of the catalyst at different positions in the later stage, so that the catalyst can fully contact the solution at each position. After the horizontal rod and the discharging unit are contacted, the cylindrical roller can be driven to rotate, thereby discharging the catalyst inside the discharging unit through the groove and moving to the inside of the raw material tank, preparing for the subsequent scattering of the catalyst. Through the cooperation of the two, the effect of continuously adding catalyst can be achieved, and the catalyst can be uniformly sprayed inside the reaction solution.

However, the materials mixed with the catalysts include not only the catalysts but also other substances. If substances with high viscosity and heavy weight are stirred, the substances may directly sink to the bottom and are difficult to mix with other substances. UTILITY MODEL CONTENTS
