Description

Technical Field

[0001] This utility model relates to the field of emulsion polymerization technology, specifically to an emulsion polymerization raw material conveying device. Background Technology

[0002] Emulsion polymerization raw material conveying equipment is a system used to controllably transport various raw materials (such as monomers, emulsifiers, initiators, water, etc.) that participate in the emulsion polymerization reaction into the reactor. It is usually a core component of the emulsion polymerization production line, and is particularly crucial for achieving efficient, stable, and safe continuous or batch polymerization processes.

[0003] First, without the stirring function of the device, monomers or additives may stratify, float or settle due to density differences, and insufficient stirring can lead to high local concentrations, causing localized explosive polymerization or violent reactions.

[0004] Secondly, traditional equipment cleaning processes are complex, time-consuming, and involve long downtime periods, which can easily lead to residual materials, causing deterioration and contamination of subsequent batches. In addition, inadequate cleaning in certain areas can become breeding grounds for microorganisms.

[0005] Finally, if the raw material inlet and outlet channels on the equipment are not separated, backflow or reverse flow can easily cause contamination. Moreover, different types of raw materials must share the same channel, which leads to difficulties in removing residues and easy blockage. Summary of the Invention
