Description

TECHNICAL FIELD

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

[0002] Early strength agent is one kind of concrete admixture, and the early strength agent of concrete refers to the admixture that 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 hydration speed of cement and promote the development of early strength of concrete. It has both early strength function and certain water-reducing and strengthening function. So far, people have developed various early strength type admixtures except for chloride salt and sulfate, such as nitrite, chromate, and organic early strength agent, such as calcium formate, urea, etc.

[0003] Due to the large land area of China, the winter period in northeast China, north China and northwest China is long, and early strength agent and early strength water-reducing agent need to be added to improve the development of early strength of concrete. In the production of concrete components, early strength type admixtures are more commonly used to stretch the reinforcement as soon as possible, speed up the turnover of formwork and increase the utilization rate of pedestal. According to statistics, the total amount of early strength agent and early strength water-reducing agent used in China each year exceeds 200,000 tons.

[0004] In the production process of traditional early strength agent, the mechanical stirring equipment used is relatively simple, and the stirring shear force is weak. After the powder and water are mixed, only the rotation of the single stirring blade is relied on to drive the rotation of the mixed liquid, which leads to a long stirring time and a large amount of bottom residues. Due to the difference in specific gravity of different raw materials, the materials with larger specific gravity tend to sink and deposit at the bottom of the stirring barrel, which may cause incomplete reaction. Moreover, the early strength agent raw materials are mainly powders such as microsilica powder, fluorite powder, CaO, Al2O3 powder, etc. These powders are prone to agglomeration to form self-suction groups. Especially for powders like CaO, due to its hygroscopicity, it is more likely to form agglomerates. If the raw materials containing powder agglomerates are directly added to the barrel, the powder agglomerates may not be fully reacted, and the stirring is uneven, which affects the subsequent process and prolongs the production time. At the same time, a large amount of materials are easily adhered to the inner side wall of the kettle body, which leads to poor dissolution of the powder raw materials, prolongs the production time, and the product quality stability is poor.

[0005] Therefore, the present application provides an early strength agent uniform stirring device. Utility model content
