Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature aging of water reducing agents, in particular to a constant temperature aging device. Background Art

[0002] Concrete water reducer is an admixture. Its main function is to reduce the water-cement ratio of concrete while maintaining the strength and durability of concrete, thereby reducing the amount of water used for mixing, improving the workability of concrete and saving water resources. In the production and processing of water reducer, constant temperature aging machine is a key equipment. Constant temperature aging machine is used to age the water reducer to improve its performance and stability. In the constant temperature aging machine, the water reducer is evenly distributed in a constant temperature environment. Through the transfer of heat energy, the molecular movement in the water reducer is accelerated, promoting the chemical reaction. At the same time, the constant temperature aging machine can also prevent the water reducer from being adversely affected by temperature changes during the aging process, ensuring the stability of the aging process and the quality of the water reducer.

[0003] Traditional constant temperature curing machines mainly provide uniform heat through electric heaters, and then use circulating fans and circulating air ducts to form a stable hot air circulation in the curing room for curing the water reducer. Only through hot air circulation, only the surface of the water reducer can be cured, which can easily cause local overheating and lead to uneven temperature distribution.
