Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as Figure 1 ~ Figure 3 As shown, the present invention provides a kind of deposition cavity device that is used for VAD to prepare optical fiber preform, comprises deposition cavity 1 and the bubble level instrument 2 that is arranged on deposition cavity 1 upper end, and deposition cavity 1 consists of top plate 12, bottom plate 15 , door panel 11, rear panel 16, left panel 14 and right panel 13 to form a closed cavity structure, wherein the door panel 11 can realize the function of opening and closing. The door panel 11, the rear panel 16, the left panel 14 and the right panel 13 all adopt a double-layer structure, including an inner panel 112 and an outer panel 111, and the distance between the inner panel 112 and the outer panel 111 is 30-45mm. This double-layer structure increases the stability of the deposition chamber 1 , ensures that the compone...

Abstract

The invention discloses a depositing cavity device for preparing an optical fiber perform by VAD and a cleaning method. The depositing cavity device comprises a depositing cavity and bubble levels. The depositing cavity is formed by encircling of a top plate, a bottom plate, a door plate, a back panel, a left panel and a right panel. The door plate, the back panel, the left panel and the right panel are of double layers and comprise inner plates and outer plates; a plurality of blowing gas outlet holes communicating with a blowing gas pipeline are uniformly formed in each of the inner plates; the bubble levels are uniformly distributed around the top plate, and a blowing gas inlet hole is formed between any two bubble levels. The device disclosed by the invention can automatically clean in a closed environment, so that loose dust is prevented from drifting away to the air in a cleaning process, the health of production operators is guaranteed, and the production operators are convenient to immediately observe and judge the position state of the depositing cavity and make corresponding adjustment by using the bubble levels, so that the long-term stability of production is ensured.

Description

technical field [0001] The invention relates to the field of manufacturing optical fiber preforms, in particular to a deposition chamber device and a cleaning method for VAD to prepare optical fiber preforms. Background technique [0002] At present, there are more than ten methods for producing optical fiber preforms in the world. There are four main methods for producing high-quality optical fibers: PCVD, MCVD, VAD and OVD, and among them, VAD method and OVD method are currently more mainstream. The preparation process of optical fiber preform soot body. The equipment for preparing fiber preform loose body by VAD method and OVD method is mainly composed of deposition chamber, raw material control cabinet, blowtorch, lifting system device and exhaust device. Among them, the deposition cavity plays a very important role in the deposition process of the preformed soot body, which ensures that the preformed soot body is not disturbed by the external environment and needs safe...
