Abstract
The utility model relates to the technical field of pipe seal structure, be a kind of mill feed end sealing device, it includes blanking tube, recycling assembly and material hollow shaft.The utility model is reasonable and compact, when mill feed end sealing fails, it is continuously collected by recycling assembly to the exosmosis slurry, and is raised to blanking tube above by sub-cavity, then is poured into blanking tube by back material hole, is retransmitted to mill bunker, to avoid the exosmosis slurry to flow to the ground of work site or mill, prevent coal slurry pollution work environment, reduce resource waste, greatly reduce the labor intensity of operating personnel and clean up slurry leakage operation risk, effectively prolong the continuous operation cycle of mill, reduce maintenance frequency;Sealing ring can form threefold seal between the inside of material hollow shaft and the outside of blanking tube together with packing seal assembly and labyrinth screw seal structure, reduce the maintenance cleaning frequency of mill feed end sealing structure, reduce the replacement frequency of sealing element.
