Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber production and manufacturing, and particularly relates to a quartz waste negative pressure crushing device for optical fiber production. Background Art

[0002] Optical fiber is made of high-purity quartz preform rods melted and drawn in a high-temperature furnace. At present, the diameter of conventional quartz preform rods is more than 200mm, while the diameter of bare optical fiber is about 125um. Before the establishment of optical fiber drawing, it is usually necessary to gradually thin the quartz material of the molten part of the cone of the preform rod by artificial cone shearing and pulling equipment. In this production process, a large amount of quartz waste with different lengths, thicknesses and end faces will be generated, and it will be temporarily stored in the solid waste barrel on the drawing tower. It will be regularly transported from the drawing tower to the designated solid waste storage point for classification and disposal.

[0003] These quartz optical fiber wastes are of different lengths, thicknesses, and ends, and are loosely piled and oversized. Direct manual transportation from the drawing tower is inefficient and poses a safety hazard. Therefore, the quartz waste in the solid waste barrel must be manually crushed next to the drawing tower before transportation.

[0004] Since the concentration of suspended particles in the air is strongly correlated with the optical fiber strength performance index, the wire drawing clean workshop has high requirements for environmental cleanliness. At present, the crushing scheme is to manually stir and crush the quartz waste in the solid waste barrel with a strip-shaped tamping rod. During the operation, a large amount of dust particles and some quartz debris will inevitably be generated at the upper mouth of the solid waste barrel, which has a great negative impact on the personal safety of the operators and the environmental cleanliness of the optical fiber production workshop. Therefore, it is necessary to improve the existing technical solutions. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a negative pressure crushing device for quartz waste used in optical fiber production in view of the above-mentioned existing problems.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a negative pressure pounding device for quartz waste for optical fiber production, characterized in that it includes a tamping rod, a sealing top cover and a joint, the sealing top cover is placed on the top of the solid waste barrel to form a sealed space with the solid waste barrel, the tamping rod is passed through the top interface of the sealing top cover and extends into the solid waste barrel, the joint is sleeved on the tamping rod and connected to the top interface of the sealing top cover.

[0007] According to the above scheme, a corrugated connecting hose is provided between the joint and the sealing top cover, and the upper and lower ends of the corrugated connecting hose are respectively connected to the joint and the top interface of the sealing top cover through clamps.

[0008] According to the above scheme, the joint is a convex sleeve structure, the upper part is positioned and fastened to the tamping rod by a tightening screw, and the lower part is connected to the corrugated connecting hose by the clamp.

[0009] According to the above solution, the sealing top cover is provided with an exhaust interface which is connected to an external exhaust fan.

[0010] According to the above solution, a gripping handle is provided on the sealing top cover.

[0011] According to the above solution, the sealing top cover is a regular tetrahedral shell structure.

[0012] The beneficial effect of the utility model is that it provides a negative pressure crushing device for quartz waste for optical fiber production. When the quartz waste is crushed by manually holding the tamping rod, the entire solid waste barrel cavity forms a closed and negative pressure environment. During the operation, the splashing of quartz debris on the upper mouth of the solid waste barrel and the influence of the generated dust particles on the cleanliness of the local environment of the clean workshop can be completely avoided, which can effectively protect the personal safety of the operators and effectively improve the quality indicators of optical fiber products in the production process.

An exhaust interface 5 is provided on the sealing top cover to be connected to an external exhaust fan.

[0019] The lower opening of the sealed top cover matches the upper opening of the solid waste barrel, and the positioning effect is achieved through its own weight and shape matching. During the crushing operation, the solid waste barrel remains closed to prevent quartz debris from splashing at the upper opening of the solid waste barrel and the generated dust particles from affecting the cleanliness of the local environment of the clean workshop; at the same time, the appropriate wind speed is adjusted by the external exhaust fan, so that the above-mentioned enclosed cavity forms a closed and stable negative pressure environment, and the dust particles are extracted and collected, which can effectively protect the personal safety of the operators and effectively improve the quality indicators of optical fiber products in the production process.

[0020] A corrugated connecting hose 6 is provided between the joint and the sealing top cover, and the upper and lower ends of the corrugated connecting hose are connected to the joint and the top interface of the sealing top cover through clamps. During the crushing process, the upper end of the tamping rod is manually moved in a small range, and the lower end of the tamping rod can be adjusted in angle through the flexibility of the corrugated connecting hose, and the stirring range can cover the entire cross-section of the solid waste barrel.

[0021] The joint is a convex sleeve structure, the upper part is positioned and fastened with the tamping rod by a tightening screw 7, and the lower part is connected to the corrugated connecting hose by a clamp. The tamping rod and the joint are in a non-fixed connection form.
