Description

Technical Field

[0001] This utility model relates to the field of concrete production equipment technology, and in particular to silos for concrete mixing plants. Background Technology

[0002] In the concrete mixing and production process, silos are an indispensable core piece of equipment, mainly used to store concrete raw materials such as cement and sand. Their performance directly affects the concrete production efficiency and product quality.

[0003] On the one hand, existing silos often lack effective mixing structures, making it easy for raw materials to clump and separate during storage, especially powdery materials such as cement. Clumping not only affects the uniformity of subsequent mixing but may also clog the discharge pipe, affecting the continuity of production. Some silos with mixing functions have simple mixing components, resulting in poor mixing effects and failing to achieve thorough mixing of raw materials. On the other hand, raw materials often contain impurities and large particles. Most existing silos do not have dedicated filtration components, allowing impurities to enter subsequent mixing processes with the raw materials, affecting the strength and quality of concrete and potentially causing wear and tear on the mixing equipment.
