Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing furnace cleaning devices, in particular to a novel high-efficiency wire drawing furnace cleaning device. Background Art

[0002] Preform rods can be used to draw material preforms for optical fibers. Fiber preform rods are the core raw materials for manufacturing quartz series optical fibers. When producing core rods, not only the core but also part of the cladding must be manufactured to ensure the optical quality of the optical fiber. Subsequently, the core rod can be thinned into many small core rods, or it can be not thinned, depending on the size of the core rod. In the second step, an outer cladding is attached to the core rod to make a preform rod. A drawing furnace will be used for wire drawing. The preform rod can be thinned or not, depending on the size of the preform rod and the drawing furnace.

[0003] In the optical fiber preform graphite induction drawing furnace, the graphite parts are exposed to high temperature for a long time, and there will be different degrees of oxides in the furnace and at the lower furnace mouth. The furnace will be cleaned after each rod is drawn.

[0004] The inventor found in his daily work that in the existing furnace cleaning and changing rods, two people are required to work together. When an operator is cleaning the furnace, the assistant needs to point the mobile vacuum cleaner hand-held at the lower furnace mouth to recover the dust to prevent it from being scattered into the air. The furnace cleaning cannot be completed independently by one person, which is time-consuming and laborious. In addition, the furnace mouth size is not completely matched with the vacuum cleaner hose, and it is not in a closed state. Some block oxides and graphite dust will fall to the ground and spread into the air, causing the environmental cleanliness to decrease. Due to the presence of a large gap, the suction force is weakened, and the dust collection effect is also reduced. At the same time, the graphite dust cannot be completely sucked away from the furnace, affecting the cleaning effect of the furnace. As a result, when cleaning the existing wire drawing furnace, two people are required to work together to clean it, which is inconvenient to clean. In addition, there is a gap between the vacuum cleaner hose and the furnace mouth, resulting in poor dust collection effect. Utility Model Content
