Description

TECHNICAL FIELD

[0001] The utility model belongs to early strength agent production technical field especially, it is early strength agent production integrated device. BACKGROUND

[0002] Early strength agent is one kind of concrete admixture, and the concrete early strength agent refers to the admixture which can improve the early strength of concrete and has no significant influence on the later strength. The main role of early strength agent is to accelerate the cement hydration speed and promote the development of early strength of concrete. It has early strength function and certain water-reducing and strengthening function.

[0003] Early strength agent is generally a composite material composed of multiple components. For example, the common cement early strength agent may contain inorganic salt calcium chloride, sodium sulfate, organic compound triethanolamine, industrial waste residue such as slag, fly ash and other components. These components have different physical and chemical properties, such as density, particle size, solubility and other differences.

[0004] In order to make them play a synergistic effect of early strength, it is necessary to mix them uniformly by mixing. The uniformity of stirring will affect the reaction rate and degree, thereby affecting the final performance of early strength agent. When using early strength agent, there may be a situation that some components are too much or too little in some areas. For example, in the case of insufficient mixing, the area containing more calcium chloride may make the cement hydration speed too fast in the early stage, resulting in cracks and other quality problems, while other areas may not achieve the expected early strength effect due to insufficient early strength components, resulting in unstable early strength effect. At the same time, there are many reaction processes in the production process, and the use of single reaction kettle production not only consumes time and effort, but also has low efficiency and high labor cost.

[0005] Therefore, the application provides an early strength agent production integrated device. UTILITY MODEL CONTENTS
