Abstract

The invention discloses a crucible hoisting device, which comprises a stainless steel shell, hoist rings, a pressure gauge, a vacuum tube, a vacuum valve, a vacuum pump and sealing rubber rings, wherein the hoist rings are fixed on the upper side of the stainless steel shell; the pressure gauge is fixed on the upper part of the stainless steel shell; one side of the stainless steel shell is provided with the vacuum tube; the vacuum valve is arranged on the vacuum tube; the vacuum valve and the vacuum pump are connected through the vacuum tube; and the lower end of the stainless steel shell is provided with the sealing rubber rings. The crucible hoisting device has the advantages that: a crucible of a single crystal furnace can be easily and safely hoisted, and a new method for hoisting the crucible of the single crystal furnace is provided.

Description

technical field [0001] The invention relates to a crucible hoisting device, in particular to a crucible hoisting device in the field of single crystal furnaces. Background technique [0002] The single crystal furnace uses a quartz crucible loaded with silicon material and placed in the thermal field of the furnace cavity to melt and then extract the crystal. In order to save the furnace loading time, it is often necessary to load the silicon material outside the furnace cavity, and then put the crucible into the furnace cavity. This is more necessary for crucibles with more molten charge. Generally, after the crucible is filled with materials, it needs tens of kilograms to hundreds of kilograms, which is difficult to move, so special lifting tools are required. SUMMARY OF THE INVENTION [0003] The present invention mainly solves the technical problems existing in the above-mentioned prior art, and provides a crucible hoisting device which is convenient for hoisting. ...
