Description

Technical Field

[0001] This utility model belongs to the field of concrete production technology. Specifically, this utility model relates to a polycarboxylate superplasticizer mother liquor production device. Background Technology

[0002] The production process of polycarboxylate superplasticizer mother liquor is a polymerization reaction of a polymer compound, which can be simplified as A+B+C=D. That is, materials from the monomer reactor and the initiation reactor are added dropwise to the reaction vessel at a set flow rate to synthesize the product. Before production begins, the materials in the monomer reactor and the initiation reactor need to be mixed evenly, but stirring is not required after the materials are evenly mixed. During production, the reaction vessel needs to be stirred to ensure sufficient contact between the reactants. However, when using a room temperature process to produce general low-performance products, the control requirements for the drop flow rate and drop time are not high. Continuing to use sophisticated control instruments would result in high investment and maintenance costs. Furthermore, the mixing effect of the materials from the initiation reactor and the monomer reactor added dropwise to the reaction vessel to obtain the polycarboxylate superplasticizer mother liquor is limited. To further reduce costs while considering product manufacturing process requirements and product quality control requirements, it is essential to design a polycarboxylate superplasticizer mother liquor production device that can guarantee the mixing effect.
