[0002] The general understanding of a reaction kettle is a stainless-steel container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are achieved. Subsequently, due to the pressure requirements during the reaction process, the design requirements for the container are also different. Production must be strictly processed, tested, and trial-run in accordance with corresponding standards. Circulating chemical additive reaction kettles are widely used in production users such as petroleum, chemical industry, rubber, pesticides, dyes, pharmaceuticals, food, etc. and various scientific research experimental projects to complete processes such as hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, alkylation, polymerization, condensation, heating and mixing, and constant-temperature reaction. A reaction kettle is a comprehensive reaction container, and the structure, function, and configuration of accessories of the reaction kettle are designed according to the reaction conditions; chemical additives are divided into process additives and functional additives, and functional additives are generally used to meet the special needs of users;

[0003] When producing oilfield chemical additives, the uniformity of inward diversion feeding is not good. Generally, the reaction kettle feeds through one side of the feeding port and then stirs through the internal mixing and stirring mechanism. However, when chemical additives are fed from the same position on one side, the feeding uniformity is poor, affecting the full mixing performance. For example, in the prior art patent CN116212802A, a circulating chemical additive reaction kettle is disclosed, which relates to the field of chemical equipment and includes a reaction barrel. The inner wall of the reaction barrel is fixedly connected with a stirring mechanism, the outer wall of the reaction barrel is fixedly connected with a rotating mechanism, the top of the rotating mechanism is fixedly connected with a moving mechanism, one side of the reaction barrel is fixedly connected with a feeding mechanism, the top of the feeding mechanism is fixedly connected with a metering mechanism, and the outer wall of the reaction barrel is fixedly connected with a discharge port. The stirring mechanism includes a stirring shaft, a spiral plate, a stirring component, a rotating component, and a fixing ring; the above invention stirs the raw materials in the reaction barrel in different directions through the setting of the stirring mechanism, improves the reaction efficiency of the reaction kettle, and at the same time, through the setting of the rotating mechanism, the stock solution can be dropped into the reaction barrel at different positions, improving the uniformity of the liquid in the reaction barrel, and controlling the amount of the stock solution entering the reaction barrel through the feeding mechanism by adjusting the metering mechanism, so as to control the ratio of the stock solution entering the reaction barrel;

[0004] In the above patent, when feeding reagents into the reaction cylinder, a circulating structure is adopted, but its guiding mechanism is complex, the cost is high, and the guiding function during feeding is single, the circulating structure is single, and the feeding uniformity is single, resulting in uneven feeding.
