[0002] In the field of industrial silicon production, according to the current needs of enterprises and the country for energy conservation and emission reduction in industrial silicon electric furnace production, the development of semi-closed industrial silicon electric furnace to fully closed industrial silicon electric furnace technology is particularly important. The success of fully closed industrial silicon electric furnace technology can effectively reduce the power consumption of product production, reduce the consumption of reducing agent (carbon) in the smelting process, improve the recovery rate of silicon, and reduce the number of operators and operating costs. In the past, after the electric furnace was fully enclosed, it was impossible to control the smelting process of the materials inside the electric furnace. There were uneven distribution of the furnace charge in the furnace, adhesion in the upper condensation zone of the charge, poor air permeability, and the charge could not sink automatically. These problems seriously affected the normal smelting of the electric furnace and made it difficult to fully realize the fully enclosed smelting production of the industrial silicon electric furnace. Therefore, it is urgent to solve the problem of material tumbling in the fully enclosed industrial silicon electric furnace, which is an important guarantee for achieving energy conservation and consumption reduction of industrial silicon electric furnaces and flue gas environmental protection.

[0017] See also Figure 1 , 2, a segmented rotating material pounding type electric furnace shell, is to segment the conventional integrated electric furnace shell at the condensation zone of the material in the furnace, and is divided into a bottom rotating furnace shell 2 and a top rotating furnace shell 3, and the furnace shell wall is made of refractory material. The bottom rotating furnace shell 2 is in a circular cup shape, and its bottom is connected to the rotating device 1. The rotating device 1 is composed of a driving device, a pin gear transmission device, an upper annular track, a lower annular track, an auxiliary beam, and a central axis. The driving device and the pin gear transmission device provide the rotating power to the upper annular track and the supporting auxiliary beam, and the auxiliary beam drives the bottom furnace shell to realize the rotation function. A top supporting flange 7 is arranged at the top of the bottom rotating furnace shell 2, and eight guide wheels 6 and eight supporting wheels 5 are arranged along the circumference of the top supporting flange 7 for supporting the top rotating furnace shell 3. The top rotating furnace shell 3 is cylindrical, and a bottom supporting flange 8 is arranged at the lower part of the top rotating furnace shell 3, and the bottom supporting flange 8 is in contact with the guide wheel 6 and the supporting wheel 5 arranged at the top of the bottom rotating furnace shell 2. The guide wheel 6 and the bottom support of the support wheel 5 are fixed with the top support flange 7 by bolt connection. The wheel surface of the guide wheel 6 contacts the outer circumferential surface of the top furnace shell to achieve circumferential rotation positioning; the wheel surface of the support wheel 5 contacts the bottom support flange 8 to provide rolling support, so as to achieve the rotational support of the top rotating furnace shell 3 on the bottom rotating furnace shell 2. A rotating pin gear 9 is provided on the outer side of the top rotating furnace shell 3 to mesh with the gear of the driving device of the top rotating device 4, driving the top rotating furnace shell 3 to rotate.
