Production apparatus of quaternary ammonium salt surfactant

Abstract

The invention discloses a production apparatus of a quaternary ammonium salt surfactant, and mainly relates to the field of chemical equipment. The apparatus includes a reaction tank, the top of the reaction tank is equipped with a material inlet and a first motor, an output shaft of the first motor penetrates through the reaction tank and then is connected with a first connecting shaft, the bottom of the first connecting shaft is equipped with mixing vanes, an auxiliary stirring device is arranged on the first connecting shaft and above the mixing vanes, the bottom of the reaction tank is provided with an opening, the opening is provided with a connecting pipe, an upper sealing plate is arranged at the top of the connecting pipe and in the reaction tank, a filter plate is arranged at thebottom of the upper sealing plate and in the connecting pipe, the bottom of the connecting pipe is equipped with a lower sealing plate, the upper sealing plate, the filter plate and the lower sealingplate are connected by a connecting rod, and the bottom of the lower sealing plate is equipped with an electric push rod. The beneficial effects of the invention comprise that the auxiliary stirring device is added on the basis of a conventional stirring device, thus internal liquid is stirred irregularly, and the stirring effect is better.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a production device for quaternary ammonium salt surfactants. Background technique [0002] Quaternary ammonium salt surfactants consist of ammonium cations [H 4 N + ] All four hydrogen atoms are replaced by organic groups as a cationic surfactant, which can be prepared by the reaction of tertiary amine and alkylating agent. The alkylating agent can be halogenated hydrocarbons such as methyl chloride and chloromethylbenzene, dialkyl sulfates such as dimethyl sulfate, alkylene oxides such as ethylene oxide, sulfonates such as methyl p-toluenesulfonate, etc. They can be used to make corresponding quaternary ammonium salt surfactants. The quaternary ammonium salt type cationic surfactant is different from the general ammonium salt type in that the former is stable in alkaline aqueous solution without amine dissociation. [0003] Since surfactants are mostly substances with larg...

AI Technical Summary

Problems solved by technology

[0003] Since surfactants are mostly substances with large foam, high viscosity, and poor fluidity, in general-purpose reactors, stirring is very difficult, there are many foams, and it is difficult to carry out rapid production. Therefore, large reactors are generally used for low-speed production with small capacity. Long time and low production efficiency

The stirring drum of the existing quaternary ammonium salt surfactant reaction device is provided with a stirring device, which generally includes a stirring shaft driven by a motor, and the stirring shaft is arranged at the center of the stirring drum. The reaction device of this structure only has a middle The stirring shaft is rotating, and the solution in the entire reaction device can only be stirred by stirring the solution around the stirring blade, the stirring effect is poor, the mixing is uneven, the stirring efficiency is low, the stratification is obvious and the storage time is short, and the stirring The stirring of the leaves makes the solution flow centrifugally, so some medium in the solution is easy to adhere to the wall of the device, and the conventional stirring device cannot well stir the medium near the side wall
