[0002] Reactors are containers for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. Reactors are widely used in industries such as petroleum, chemical, rubber, pesticide, dye, medicine and food. Synthetic resin refers to a resin product obtained by chemical synthesis of simple organic matter or chemical reaction of certain natural products. Resin reactors are key equipment for the production of unsaturated polyester resins, phenolic resins, epoxy resins, ABS resins and paints.

[0003] During the production reaction process, it is necessary to prepare various auxiliary materials and put them into the reactor for proportioning and adding. During the adding process, the auxiliary materials need to be quantitatively controlled. At present, in the actual production process, auxiliary materials are usually contained in iron barrels or leather barrels. The auxiliary materials are added by manpower using a small cart to transfer the auxiliary materials to a mobile electronic scale, and then two people work together to complete the auxiliary material addition process. During this period, there are safety hazards such as unstable carts and shaking materials during the extraction process. There are also factors such as metering fluctuations that affect the final material index. In addition, two people are required to work together to complete the entire small material auxiliary material addition process, and the workers' labor intensity is high. When adding auxiliary materials, the amount of auxiliary materials added cannot be controlled, which can easily lead to excessive or insufficient addition of auxiliary materials, which has a great impact on product quality.
