Automatic quartz reaction tube cleaning machine and automatic tube cleaning method thereof

Abstract

The invention discloses an automatic quartz reaction tube cleaning machine and an automatic tube cleaning method thereof. The automatic quartz reaction tube cleaning machine comprises a housing divided into an upper chamber and a lower chamber, a rotation switching mechanism is arranged at the top of the housing, the left side and the right side of the upper chamber are provided with a pipe inlet door and a pipe outlet door respectively, a first automatic door and a second automatic door are arranged in the upper chamber sequentially from left to right, the upper chamber is divided into a to-be-cleaned area, a cleaning area and a drying area by the first automatic door and the second automatic door from left to right, a first holder plate, a second holder plate and a third holder plate are arranged in the to-be-cleaned area, the cleaning area and the drying area respectively, the lower chamber is provided with a cleaning tank inside, and the cleaning area is communicated with the cleaning tank through an openable flushing door. The rotation switching mechanism controls the first, the second and the third holder plate to move according to a certain sequence by commands transmitted by a PLC (programmable logic controller). The automatic quartz reaction tube cleaning machine has the advantages that labor operation and halt time of equipment are reduced, cleaning is more convenient and efficient, high-efficiency operation of equipment is realized, and production requirements of successive process are well met.

Description

technical field [0001] The invention relates to a cleaning device for quartz reaction tubes, in particular to an automatic cleaning machine for quartz reaction tubes and an automatic cleaning method for the tubes. Background technique [0002] With the rapid development of the optical fiber industry, the quality requirements of optical fibers are getting higher and higher, and optical preforms are the raw materials for optical fiber production, and their manufacturing process and quality are particularly important, so the use efficiency of equipment related to the manufacture of optical preforms is also need to be further improved. [0003] Optical fibers are generally produced by vapor deposition. The vapor of high-purity metal halide reacts with oxygen to form some oxide particles. These oxide particles will be deposited on the quartz tube and sintered to form an optical preform. After fiber drawing, coating The bare optical fiber is formed after the process, and the opti...
