Efficient reaction device for preparing polycarboxylic acid

Abstract

The invention discloses an efficient reaction device for preparing polycarboxylic acid, and belongs to the field of liquid level indicating devices. The efficient reaction device for preparing the polycarboxylic acid comprises a reaction kettle main body and a floating block, a heating cover fixedly sleeves the reaction kettle main body, and the strip-shaped grooves are formed on one side wall ofthe reaction kettle main body and one side wall of the heating cover; the two strip-shaped grooves are opposite to each other, the observation plates are fixedly embedded in the strip-shaped grooves,and the inner wall of the reaction kettle body is fixedly connected with a strip-shaped arc plate; the observation plates are opposite to the strip-shaped arc plate, a plurality of bulbs are embeddedinto the left side of the inner wall of the strip-shaped arc plate, and the floating block is arranged at the inner side of the strip-shaped arc plate; an ejector rod is fixedly connected at the center of the top end of the floating block, and a sealing box is arranged at the top of the strip-shaped arc plate. According to the reaction kettle, the height of the liquid level in the reaction kettlecan be clearly observed, when boiling occurs in the reaction kettle and the liquid level rises abnormally, the automatic alarming is achieved, and the safe production is guaranteed.

Description

technical field [0001] The invention relates to the field of liquid level indicating devices, more specifically, relates to a high-efficiency reaction device for preparing polycarboxylic acid. Background technique [0002] Water reducer is an important concrete admixture and one of the important products of the new building materials pillar industry. High-efficiency water reducer not only greatly improves the mechanical properties of high-strength concrete, but also provides a simple and easy construction process. Polycarboxylic acid High-efficiency superplasticizer is the third generation of high-performance superplasticizer developed after the ordinary water-reducer represented by wood calcium and the high-efficiency superplasticizer represented by naphthalene series. It is currently the most cutting-edge, high-tech, It is a high-efficiency water reducer with the best application prospect and the best comprehensive performance. [0003] The existing reactor needs manual m...

AI Technical Summary

Problems solved by technology

[0003] The existing reactor needs manual monitoring of the liquid level in the reactor, in order to prevent the boiling of the reactor from causing raw materials to gushe out, affect the reaction process, and avoid safety accidents, but a large amount of foam will be generated during the reaction of the reactor, which will As a result, the liquid level cannot be seen clearly, the accuracy of the operator's observation is poor, and the change of the liquid level in the reactor cannot be correctly monitored
