Description

Technical Field

[0001] This utility model relates to the field of precious metal catalyst technology, and in particular to a catalyst screening reaction device. Background Technology

[0002] Noble metal catalysts are highly efficient catalytic materials with noble metals such as platinum (Pt), palladium (Pd), and rhodium (Rh) as active components. They significantly reduce the activation energy of reactions by adsorbing reactants and forming intermediate active compounds through their unfilled d-electron orbitals. These catalysts possess properties such as high temperature resistance, oxidation resistance, and corrosion resistance, and are widely used in fields such as petroleum reforming, automotive exhaust purification, and fine chemical synthesis.

[0003] In the production and processing of precious metal catalysts, a reaction apparatus is typically used to mix and react the catalyst raw materials. Since precious metal catalysts usually require the addition of precious metal raw materials, if the volume of the precious metal raw material is too large, incomplete reaction can occur, leading to a significant reduction in the reaction efficiency of the precious metal catalyst.

[0017] Specifically, the sealing door mechanism consists of a hinge 16, a sealing door panel 17, and a door lock 18. The hinge 16 is fixedly connected to the left side of the fixed frame 7.
