Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chemical kneading equipment, more specifically, relates to a kneading equipment for hydrogenation catalyst production and processing. BACKGROUND

[0002] In the field of hydrogenation catalyst production, traditional kneading equipment and processes have many problems, which seriously restrict the production quality, efficiency of the catalyst, and the convenience and applicability of equipment maintenance.

[0003] I. Kneading effect problem Low mixing uniformity: Traditional kneading equipment usually uses single type or similar angle stirring paddles. When kneading hydrogenation catalyst production raw materials, it is difficult to produce different shear forces on the compounds, resulting in poor mixing uniformity. This makes the catalyst carrier mixing insufficient, the pore distribution inconsistent, and further affects the activity stability of the catalyst, which cannot meet the strict requirements of high-end hydrogenation reactions on catalyst quality.

[0004] Dead zone problem: In the kneading process of traditional equipment, center deposition or edge dead zone phenomenon often occurs. The material in these areas cannot be fully stirred and mixed, not only reducing the overall mixing effect, but also possibly causing part of the raw materials not to participate in effective reaction, affecting the performance consistency of the catalyst.

[0005] II. Equipment maintenance problem Convenient replacement of tool bit: The tool bit of traditional kneading equipment usually adopts fixed design. When replacing the tool bit, complex disassembly and installation steps are required, which consumes a lot of time and manpower. This not only increases the equipment maintenance time and reduces the production line continuous operation capacity, but also makes the equipment unable to produce normally during maintenance, affecting the production efficiency.

[0006] High frequency of replacement of spare parts: Due to the lack of modularity in the design of traditional equipment tool bit, once the tool bit is worn or damaged, it often needs to be replaced as a whole, increasing the frequency and cost of replacement of spare parts. Moreover, the fixed tool bit is difficult to adapt to the diversified production needs of different catalyst formulations, limiting the application scenarios of the equipment.

[0007] III. Mixing efficiency problem Difficult to handle high viscosity materials: For high viscosity hydrogenation catalyst materials, the paddle design of traditional kneading equipment cannot effectively reduce the material resistance, which easily leads to material aggregation during stirring. At the same time, traditional equipment is difficult to produce sufficient local turbulence under high viscosity working conditions, and cannot deeply mix the local areas of high viscosity slurry such as the corner of the bin bottom and the blind area of the main paddle vortex, affecting the mixing effect and efficiency.

[0008] Micro-mixing is insufficient: traditional equipment has low mixing efficiency at the micro level, and cannot effectively force materials to converge to high pressure areas to enhance micro-mixing effect. Especially when dealing with complex catalyst formulations, it is difficult to achieve sufficient mixing at the micro scale, affecting the quality stability and performance of the catalyst. SUMMARY
