Description

Technical Field

[0001] The utility model relates to the technical field of concrete storage, in particular to a moisture-proof storage bin. Background Art

[0002] Concrete specifically refers to an engineering composite material in which aggregates (such as sand and stone) are bonded together by cementitious materials (such as cement). It is an indispensable material in the modern construction industry. The main raw materials of existing concrete include cement, water, powder, sand, chemical admixtures and mineral admixtures, among which powder is used to occupy the gaps and fill the gaps between cement particles, making the concrete more compact and solid. In the production and processing of concrete, in order to facilitate the management of powder and prevent the powder from absorbing water and deteriorating, which will affect subsequent production, the powder needs to be stored in a storage bin. At the same time, in order to ensure the looseness of the powder, facilitate the uniform distribution and flow of the powder, and prevent the powder from being piled up and compacted in the storage bin, the storage bin also needs to have a certain ventilation capacity. However, the existing storage silos have poor moisture-proof performance and are easily introduced with water vapor during ventilation. The powder has a certain water absorption capacity and is easily deteriorated and agglomerated when stored in the storage silo, thus affecting the subsequent production, processing and use of concrete. Agglomeration can easily lead to blockage of the discharge port, affecting the discharge rate. Therefore, it is urgent to improve the existing storage silos. Utility Model Content
