Description

Technical Field

[0001] The utility model relates to the technical field of ethoxylated alkyl sodium sulfate production, in particular to a mixing device for producing ethoxylated alkyl sodium sulfate. Background Art

[0002] Neutralization of sodium ethoxylated alkyl sulfate is an indispensable step in its production process. By precisely controlling parameters such as the neutralization ratio and temperature, AES products with stable performance and high active ingredient content can be prepared. The product form of sodium ethoxylated alkyl sulfate is relatively special. It is a flowing gel paste when the concentration is 70%, a transparent liquid when the concentration is less than 28%, and a gel paste that is difficult to flow when the concentration is between 30% and 65% or greater than 75%. Therefore, it is difficult to use in powders. In addition, sodium ethoxylated alkyl sulfate has a sticky characteristic. Even if it is produced by agglomeration molding technology, the dosage will be limited and generally cannot exceed 2%.

[0003] When the sodium ethoxylated alkyl sulfate undergoes a neutralization reaction, an alkaline substance needs to be added. Since the alkaline substance is added later, it will be on the upper side of the sodium ethoxylated alkyl sulfate. It takes a long time of stirring to fully mix the two. The long mixing time results in a large amount of power consumption of the equipment.

[0004] In addition, due to the high viscosity of the mixture, some materials will stick to the stirring roller and are difficult to clean. Therefore, a mixing device for producing ethoxylated alkyl sodium sulfate is proposed. Utility Model Content
