Description

Technical Field

[0001] The utility model relates to the technical field of resin storage, and is a finished product silo device for preventing bridging of paste resin materials during unloading. Background Art

[0002] At present, the finished resin silo is used as a temporary storage silo for resin powder. The resin particles must first be ground into paste resin and then put into the finished resin silo for storage. Due to the poor fluidity of the finished resin paste, there are frequent bridging problems in the silo, and the material discharge is not smooth. The staff needs to knock on the silo frequently to make the resin discharge in the silo smooth.

[0003] Drying workers in each team of a chemical company need to knock on the silo wall 8 to 10 times a day, each time using a wooden hammer to knock the finished product silo to the conical outlet. Prolonged knocking causes deformation of the conical outlet of the resin finished product silo, reducing the smoothness and flatness of the inner wall of the silo outlet, increasing the possibility of powder accumulation and bridging. On the other hand, prolonged knocking on the silo also increases the labor intensity of the workers, and in hot summer weather, increases the risk of heatstroke for the workers. In addition, the manual knocking process will shake off the fine dust attached to the outer wall of the silo, threatening the occupational health of the workers.

[0004] The above-mentioned manual knocking on the resin finished product silo to prevent the resin from piling up and bridging inside the silo has problems such as high labor intensity, low work efficiency, and dangerous operation. These problems have become technical difficulties that are difficult for enterprises to overcome. Summary of the Invention
