[0037] During the working process of this embodiment:

[0038] The centrifugal fan 33 and the pneumatic sliding door 14 are turned on by remote control, and the hook of the electric hoist 51 lifts the handle 9, lifts the pole piece combustion barrel 2 and places it in the high temperature treatment pool 1, and the pole piece combustion barrel 2 is placed.
