Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a new type of reaction kettle for producing a water reducing agent. Background Art

[0002] Water reducer is a chemical substance that can reduce the water-cement ratio in concrete and improve the working performance of concrete. It reacts with the water in concrete to reduce the friction between water and cement particles, thereby making the concrete more fluid, plastic and slump, making construction easier. In the production process of water reducer, a reactor is required to stir and mix the various raw materials to ensure that the various ingredients are evenly dispersed and the reaction can proceed fully, so as to ensure that the reaction materials are fully in contact and react throughout the process.

[0003] However, the reactor currently used for the production of water reducers usually directly adds raw materials into the reactor and stirs them. In this way, multiple raw materials are not preliminarily mixed. Although directly pouring the raw materials into the reactor and stirring them can speed up the mixing speed, it will lead to uneven dispersion and some raw materials not fully participating in the reaction, making it difficult to control the reaction rate and product formation during the reaction, which is not conducive to the conversion of reactants and the quality control of products, and reduces the production efficiency of water reducers.

[0004] Therefore, a new type of reactor for water reducing agent production is proposed to solve the above problems. Utility Model Content
