Problems solved by technology

[0002] In the MCVD or PCVD rod making process, the transportation path of raw materials such as chelate and aluminum trichloride is very strict on temperature control. Once the temperature is too high or too low somewhere, or the raw material does not reach the reaction zone due to high temperature Reaction or carbonization, or recondensation of gasified raw materials due to too low temperature, the final result will lead to the scrapping of the preform
[0003] At present, the widely used feeding pipe is heated by electric heating wire. Since the winding of electric heating wire is difficult to be uniform and dense, the temperature of the material will not be uniform; in addition, the temperature measured by the temperature measuring probe at different positions will have obvious differences. For example, the temperature near the heating wire will be high, otherwise the measured temperature will be low, which is not conducive to temperature monitoring and control; in addition, the heating wire is easy to burn out and has a short service life

Abstract

The invention discloses a chelate conveying pipe which comprises multiple conveying pipes and a sleeve. The conveying pipes penetrate into the sleeve from the feeding end of the sleeve and penetrate out of the sleeve from the discharging end of the sleeve; heating liquid media are filled between an inner cavity of the sleeve and the conveying pipes; and a liquid inlet pipe and a liquid outlet pipe are connected onto the sleeve. According to the chelate conveying pipe provided by the invention, the material conveying quality is improved, the machining quality is improved, and the service life is prolonged.

Description

technical field [0001] The invention specifically relates to a chelate feeding tube. Background technique [0002] In the MCVD or PCVD rod making process, the transportation path of raw materials such as chelate and aluminum trichloride is very strict on temperature control. Once the temperature is too high or too low somewhere, or the raw material does not reach the reaction zone due to high temperature Reaction or carbonization, or recondensation of gasified raw materials due to too low temperature, the final result will lead to the scrapping of the preform. [0003] At present, the widely used feeding pipe is heated by electric heating wire. Since the winding of electric heating wire is difficult to be uniform and dense, the temperature of the material will not be uniform; in addition, the temperature measured by the temperature measuring probe at different positions will have obvious differences. For example, the temperature near the heating wire will be high, otherwise...
