Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for enclosed silos, specifically an automatic dust removal device for feeding enclosed silos. Background Technology

[0002] A closed silo is an enclosed space designed to store and protect dust, particles, or other materials. It is commonly used in industrial production environments to prevent material leakage or contamination, while also controlling material flow and discharge. During silo loading operations, a large amount of dust is generated. To effectively control dust inside the silo and prevent dust pollution or disruption to production equipment, dust removal equipment is required. In existing technologies, dust easily accumulates in the suction port and suction pipe, reducing suction efficiency. Regular cleaning of the suction port and connecting pipes is necessary. However, cleaning the suction port typically requires workers to climb up to access it, especially when the suction port is located at a high or inaccessible position, increasing the difficulty of cleaning and posing certain safety hazards to workers.

[0003] Therefore, those skilled in the art have provided an automatic dust removal device for closed silo feeding to solve the problems mentioned in the background art. Utility Model Content
