Blank machining equipment for graphite thermal field and machining method thereof

Abstract

The invention discloses blank machining equipment for a graphite thermal field. The equipment comprises a bottom plate, arc-shaped vertical plates, sliding mechanisms, lifting mechanisms and a stirring mechanism, the two ends of the top face of the bottom plate are provided with a pair of arc-shaped vertical plates, a supporting plate is arranged between the two arc-shaped vertical plates, a crucible barrel is installed in a circular through hole, and the outer side face of the crucible barrel is sleeved with a heat preservation barrel. The two sides of the outer wall of the heat preservationcylinder are in sliding connection with the supporting plate through the multiple pairs of sliding mechanisms. The two ends of a circular cover plate are movably connected with the corresponding arc-shaped vertical plates through a pair of lifting mechanisms. The end part of a motor shaft of a motor and the stirring mechanism synchronously rotate. The invention further discloses a machining methodof the blank machining equipment for the graphite thermal field. The problems that a crucible is inconvenient to install and lift, a graphite material is non-uniformly stirred, and an opening of thecrucible is not tightly sealed are solved, through cooperative use of all mechanisms, the operation steps are simplified, the labor burden of workers is relieved, and the processing and production efficiency of the graphite material is improved.

Description

technical field [0001] The invention relates to the technical field of graphite processing, in particular to blank processing equipment and a processing method for graphite thermal fields. Background technique [0002] At present, in the production of monocrystalline silicon, the monocrystalline silicon growth furnace is an indispensable production tool. The main equipment in the monocrystalline silicon growth furnace is a graphite thermal field. The graphite thermal field is generally composed of an insulation cylinder, a heater, and a graphite crucible. and a quartz crucible. [0003] There are still some shortcomings in the graphite thermal field. 1) The crucible is not easy to lift and adjust, which brings inconvenience to the operation of the staff, and the traditional installation method is relatively cumbersome; 2) Manual stirring is required for stirring. And the graphite material in the crucible cannot be evenly stirred, which affects the production of graphite bla...

Problems solved by technology

[0003] There are still some shortcomings in the graphite thermal field. 1) The crucible is not easy to lift and adjust, which brings inconvenience to the operation of the staff, and the traditional installation method is relatively cumbersome; 2) Manual stirring is required for stirring. And the graphite material in the crucible cannot be evenly stirred, which affects the production of graphite blanks; 3) When the graphite material in the crucible is stirred, the opening end of the crucible cannot be guaranteed to be sealed, resulting in splashing of graphite material, which affects the personal life of workers Safety
