Auxiliary furnace chamber lifting and rotating device for single crystal furnace

Abstract

The invention relates to the field of single crystal furnaces, and especially discloses an auxiliary furnace chamber lifting and rotating device for a single crystal furnace. The auxiliary furnace chamber lifting and rotating device is arranged on one side of a main furnace chamber and is connected with an auxiliary furnace chamber, and comprises a supporting frame, a lifting mechanism, a rotatingmechanism and a connecting mechanism connected with the auxiliary furnace chamber. The supporting frame is connected with a main furnace chamber rack; a main shaft is arranged on the supporting frame; the lifting mechanism is arranged on the supporting frame and movably connected with the main shaft, the rotating mechanism is arranged at the top of the supporting frame and connected with the mainshaft, one end of the connecting mechanism is connected with the lifting mechanism, the other end of the connecting mechanism is connected with the rotating mechanism, and the connecting mechanism isarranged on the side face of the main shaft and fixedly connected with the main shaft. The single crystal furnace has the effects that the operation stability of the single crystal furnace is improved, and the long-term safe and reliable operation of the single crystal furnace in the production process is ensured.

Description

technical field [0001] The present application relates to the field of single crystal furnaces, in particular to a lifting and rotating device for an auxiliary chamber of a single crystal furnace. Background technique [0002] At present, the single crystal furnace is the equipment with the highest production capacity for the production of solar grade single crystal silicon rods. The method of pulling monocrystalline silicon rods for a second time will increase production capacity. This requires that the sub-furnace chamber of the single crystal furnace be raised and unscrewed several times when preparing silicon rods to realize multiple feeds. [0003] At present, most of the auxiliary furnace room lifting devices of single crystal furnaces on the market are driven by hydraulic pressure, which is relatively expensive and not very convenient for later maintenance; the rotating device is mostly driven by a wedge wheel, which is used during the frequent rotation of the auxili...

AI Technical Summary

Problems solved by technology

[0003] At present, the auxiliary furnace room lifting device of the single crystal furnace equipped on the market is mostly driven by hydraulic pressure, which is relatively expensive and not very convenient for later maintenance; the rotating device is mostly driven by wedge wheel, which is used during the frequent rotation of the auxiliary room furnace In the middle, the wedge-shaped belt is easy to loosen and slip, and at the same time, the wedge-shaped belt is prone to fatigue and breakage after long-term use

[0004] In view of the above-mentioned related technologies, the inventor believes that there are defects such as unstable operation and low reliability of the lifting and rotating device of the sub-furnace chamber of the single crystal furnace
