[0035] When in use, the sleeve 601 and the electric heating tube 602 can simultaneously heat the material during the vertical feeding process, thereby increasing the functionality of the device and improving the processing efficiency of the germanium single crystal.

[0036] For example, Figure 2 As shown, the utility model also includes that the back of the mounting frame 1 is connected to the recovery groove 502 by bolts, and the recovery groove 502 is connected to the guide groove 4, the recovery groove 502 is connected to the exhaust fan 501 by bolts, and the air inlet end of the exhaust fan 501 is located in the recovery groove 502, and a filter plate 503 is arranged in the recovery groove 502.
