Description

Technical Field

[0001] This utility model relates to the field of reactor feeding technology, specifically to a cement grinding aid reactor feeding device. Background Technology

[0002] Cement grinding aids are industrial products synthesized by simple physical mixing of various organic and inorganic compounds at room temperature and pressure. Their quality depends on the stability of the composition and content of each component. Currently, cement grinding aids are synthesized by adding various raw materials to a mixing tank. The common practice is to directly feed the raw materials and liquids through the feed pipe. Under the agitation of the mixer, the raw material liquid undergoes a chemical reaction and generates heat. However, due to the overly concentrated feed of the raw material liquid, the component distribution in the reaction vessel is very uneven, causing localized high temperatures, high pressures, and explosive agglomeration during the reaction. This seriously affects product quality. Furthermore, the presence of a small amount of large solid particles can easily lead to incomplete reaction if not treated. The fact that solid and liquid raw materials share the same feed pipe can cause the raw materials to adhere to the pipe wall, affecting subsequent feeding, posing a problem. Utility Model Content
