Concrete additive drying device

Technical Field

The invention relates to the technical field of concrete additive processing, in particular to a concrete additive drying device.

Background

A concrete water reducing agent is a concrete admixture which can reduce the mixing water consumption under the condition of keeping the slump of concrete basically unchanged, and most of the concrete admixture belongs to anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer and the like. The concrete water reducing agent takes methylnaphthalene and sulfur trioxide as raw materials, and is prepared into finished products by sulfonation, condensation, neutralization and other reactions, and finally drying by a spray dryer, transportation, packaging and warehousing.

However, the water reducing agent contains hydrophilic groups, so that the packaged concrete water reducing agent is easy to absorb water and agglomerate in long-time storage and transportation processes, and the water reducing rate is reduced in use, so that the concrete water reducing agent needs to be dried again. At the moment, the shape of the water reducing agent is that the powder is not suitable for drying by a spray dryer, the using amount is small during use, large-scale equipment is not needed, the traditional drying device mostly adopts stirring drying or fan drying, and therefore a large amount of water reducing agent powder is stuck inside the drying device and certain loss is caused. Therefore, a concrete admixture drying device is provided.
