Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a precision adjustment control system for a reaction kettle. Background Art

[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

[0003] The stirring mode and stirring flow direction that can be achieved by the agitator in the common reactor are fixed and single. During the reaction process, the viscosity, fluidity, density and other characteristics of the material may change. If the stirring mode and flow direction are fixed and cannot be flexibly adjusted according to the changes in the material, the stirring effect may be reduced, and the material may not be stirred sufficiently in some places, resulting in incomplete local reaction or uneven mixing. The height of the transmission reactor is fixed, so it cannot adapt to the receiving barrels of different heights during discharge, which will lead to the inability to accurately dock during the discharge process, which may cause the liquid to splash or leak. Especially when the height of the receiving barrel is low, the liquid may overflow or fail to be completely poured into the receiving barrel, resulting in a waste of raw materials. In view of the above problems, a precise adjustment control system for the reactor is proposed to solve them. Summary of the invention
