Description

Technical Field

[0001] The utility model belongs to the technical field of catalyst production, and particularly relates to a conveying device for residual oil hydrogenation catalyst production. Background Art

[0002] In a chemical reaction, a substance that can change the chemical reaction rate of the reactants (both increase and decrease) without changing the chemical equilibrium, and whose quality and chemical properties do not change before and after the chemical reaction is called a catalyst (solid catalyst is also called a catalyst). According to statistics, more than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical, environmental protection, etc. Residue oil hydrogenation catalysts are mainly divided into four categories: protective agent, demetallization agent, desulfurization agent, and denitrification agent. Therefore, when producing residue oil hydrogenation catalysts, it is necessary to transport and mix a variety of catalyst raw materials together. In the prior art, various raw materials are often manually put into the mixing tank one by one, and then mixed and stirred through the mixing tank. In this way of putting, the first material put will fall to the bottom of the mixing tank, and the later material will be at the top of the mixing tank. In this way, when mixing and stirring, the material below the mixing tank and the material above the mixing tank are difficult to be completely mixed together, which not only takes a long time to mix, but also affects the mixing quality. Therefore, the existing residue oil hydrogenation catalyst is inconvenient to put in during production, and multiple raw materials need to be put in one after another, which will affect the mixing time and mixing quality, and the materials are prone to cause material blockage during the feeding and transportation process.
