Control method of intelligent polycarboxylate superplasticizer reaction kettle

Abstract

The invention discloses a control method of an intelligent polycarboxylate superplasticizer reaction kettle. The method includes the steps of: 1, conducting pressurization in a titration box and adding reagents required for preparation of a polycarboxylate superplasticizer into a mixing vessel, and adding water into the mixing vessel; 2, using MCU to control the rotation of a transmission shaft and driving the mixing vessel to do periodic reciprocating rotation to mix liquid in the mixing vessel evenly, heating air and sending air into the shell; 3, using MCU to control the overturn of the mixing vessel, and pouring the superplasticizer in the mixing vessel into a superplasticizer trough, and discharging the superplasticizer out of the shell along a pipeline connected to the superplasticizer trough; 4, conducting overturn again to make the opening of the mixing vessel opposite to a flushing head disposed on the shell inner wall, using a flushing pump to pump water in a flushing water tank to flush the inner side wall of the mixing vessel; 5, at the end of flushing, using MCU to control the mixing vessel in terms of swing the opening of the mixing vessel downward for spin-drying ofthe mixing vessel; and 6, using MCU to control overturn of the mixing vessel to an initial position. The method can improve the superplasticizer preparation quality.

Problems solved by technology

The polycarboxylate superplasticizer reactors in the prior art are generally controlled at room temperature, and cannot provide suitable temperatures according to the needs of different stages of the reaction, which leads to problems such as insufficient reaction and low product yield.

Superplasticizers include modified lignosulfonate superplasticizers, naphthalene-based superplasticizers, melamine resin-based superplasticizers, sulfamate-based superplasticizers, and polycarboxylate superplasticizers In the synthesis process of various water reducers, the uniformity of stirring between the material components and the control accuracy of the temperature during the stirring process are mainly considered. Take polycarboxylate water reducers as an example, if the stirring is not uniform, there will be water reduction. The performance of the water reducing agent is unstable. If the temperature in the reactor is not well controlled, the performance of the polycarboxylate superplasticizer will vary. Now all kinds of superplasticizer synthesis reactors basically have uneven stirring or appear due to too much material. Insufficient reaction between components and difficult temperature control
