Description

Technical Field

[0001] This utility model belongs to the technical field of raw material storage equipment, specifically relating to a commercial concrete raw material storage silo. Background Technology

[0002] Commercial concrete, also known as ready-mixed concrete, refers to cement concrete made by mixing cement as a binder, sand and stone as aggregates, and water (with or without admixtures and additives) in a certain proportion, followed by mixing, molding, and curing. During the production of commercial concrete, raw materials are usually stored in storage silos for use in subsequent production.

[0003] According to the patent announcement number CN219770725U, a commercial concrete raw material storage silo is known prior art. Although this patent has the advantage of storing and drying raw materials, the technical solution of this patent still has the following defects in actual use: In this patent, because the commercial concrete raw material is stored in a single storage box, there is no mixing and tamping device inside, which is not conducive to the mixing of commercial concrete raw materials to form gaps, thus not conducive to ensuring sufficient contact between heat and raw materials, and cannot guarantee the moisture-proof and drying effect. At the same time, commercial concrete raw materials are prone to accumulation and blockage when discharging. In addition, the use of only setting a heat sealing device on the side of the storage space cannot achieve uniform heat sealing output, and it does not have the function of simultaneous re-drying during discharge, resulting in poor drying effect.
