Description

Technical Field

[0001] This utility model belongs to the field of silo equipment, and specifically relates to a silo with dual servo collaborative control. Background Technology

[0002] Silos are core equipment used in industrial production, warehousing and logistics for storing and transferring solid materials (mainly powders, granules, lumps, etc.). Currently, these silos are prone to material flow stability issues during material handling. Because they rely on a single power unit to control the auger conveyor, it is difficult to simultaneously address the need for material agglomeration. When handling materials with cohesive properties such as powders and high-humidity granules, the material inside the silo is prone to bridging due to its own viscosity, silo wall friction and changes in ambient humidity, leading to interruption of discharge or sudden changes in flow rate. This is related to the material characteristics and the fact that the fixed structure of the discharge tank makes it difficult to dynamically adapt to the material state. Conventional methods to maintain flow include installing vibration devices on the silo walls or periodic manual cleaning, while controlling the feed rate by setting a fixed auger speed. However, vibration devices have limited effectiveness in breaking up bridging of highly viscous materials, and manual cleaning requires frequent shutdowns, affecting production continuity. Fixed speeds cannot be adjusted in real time according to the actual flowability of the material, easily causing fluctuations in feeding accuracy. Especially when the material characteristics change slightly, it is difficult to balance conveying efficiency and stability. These methods cannot achieve dynamic coordination between material state and conveying rhythm, and require significant manpower to maintain equipment adaptability in the long run. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content
