A device and method for arranging vad and ovd

Abstract

The invention discloses equipment and method for arranging a VAD and an OVD. The equipment comprises a multi-storey plant and a deposition tower penetrating through all storeys from bottom to top. A pedestal of the deposition tower is arranged on the first storey of the plant, and the top of the deposition tower reaches but does not make contact with the top of the plant. A VAD device body or an OVD device body is suspended in the space of each storey through the deposition tower, and the device bodies are suspended on the deposition tower in a spiral arraying mode from the first storey to the top storey. VAD auxiliary devices or OVD auxiliary devices are installed on the storeys of the corresponding VAD device bodies or the OVD device bodies, and the VAD auxiliary devices or OVD auxiliary devices surround the deposition tower. The equipment improves the utilization efficiency of the deposition tower, improves the utilization rate of the plant, improves the utilization rate of clean space of the plant and lowers the cost.

Description

technical field [0001] The invention belongs to the field of optical fiber preform manufacturing, and in particular relates to a device and method for arranging VAD and OVD, and more specifically relates to a method for arranging VAD equipment body, vertical OVD equipment body, and auxiliary equipment thereof. Background technique [0002] Due to the rapid development and expansion of domestic optical fiber preform preparation technology in recent years, it is very unlikely that any optical fiber preform manufacturer will obtain high profits through technological monopoly. Therefore, it can be predicted that for a very long period of time in the future, the competition among preform production enterprises will transform into a competition centered on controlling production costs. In the cost structure of prefabricated rod preparation, land cost, plant construction cost, fixed equipment investment, and operating cost to maintain the temperature, humidity and cleanliness of th...

AI Technical Summary

Problems solved by technology

[0004] The plant structure and equipment distribution of this design are relatively simple, so the plant construction and equipment installation in the early stage will be easier, but the use efficiency of land, plant and deposition towers is not high, and because the use efficiency of clean areas is relatively low. The unit cost of clean area maintenance in the production process will also be relatively high

Therefore, this design will eventually make the proportion of soil, plant, and fixed equipment investment allocated to the prefabricated rod manufacturing cost relatively high.
