Description

Technical Field

[0001] The utility model relates to the technical field of steel plate silo storage, and in particular to a module unit and a modular assembled multi-cavity corrugated steel plate silo. Background Art

[0002] Brick-concrete silos and reinforced concrete silos take a relatively long time to build, and concrete is greatly affected by seasons and climate conditions, prone to temperature cracks and shrinkage cracks, making it extremely inconvenient to renovate, dismantle or relocate. In addition, brick-concrete silos and reinforced concrete silos have poor water resistance, high moisture absorption, easy leakage, poor moisture resistance, and the stored grain is prone to mildew and rot.

[0003] Since the introduction of galvanized corrugated steel plate prefabricated silos in my country in 1982, they have achieved rapid development in China due to their advantages of light weight, low foundation requirements, low cost, excellent durability, and convenient management. In addition, their supporting systems are complete, the degree of mechanical automation is high, and they can better meet the process requirements of safe grain storage. However, the sealing of traditional prefabricated steel silos is relatively poor, and the storage effect of powdery materials and perishable materials is poor; their installation process is relatively complicated, and it is also difficult to dismantle, relocate or transform them after installation; in addition, due to the low longitudinal stiffness and thin thickness of corrugated steel plates, they are prone to vertical buckling under loads such as their own weight; the maximum circumferential tension provided by traditional single-layer or single-cavity corrugated steel plates is relatively small. The above characteristics limit the scope of use of corrugated steel silos. In addition, for materials that have requirements for storage temperature (such as seeds, etc.), when they are in areas with large temperature differences (such as the cold regions of Northeast China, etc.), the traditional single-layer prefabricated steel silos have poor thermal insulation performance, which can easily cause the external temperature to affect the quality of stored materials. Temperature regulation in the silo requires continuous work, and storage costs will also increase significantly. Utility Model Content
