Description

Cleaning tool for electrode hole of reduction furnace Technical Field The application relates to the technical field of reducing furnace cleaning equipment, in particular to the technical field of cleaning tools for electrode holes of a reducing furnace. Background In the production of polysilicon, a reducing furnace is core equipment, and the improved Siemens method is adopted to produce high-purity polysilicon. The method converts trichlorosilane (SiHCl 3) into polysilicon through high-temperature reduction reaction. The improved Siemens method has the advantages of remarkable energy saving and consumption reduction, low cost, good quality and the like, does not pollute the environment, and has obvious competitive advantage. In the production process of the reduction furnace, heat energy required for the reduction reaction is mainly provided by conductive heating of a high-voltage current through a copper electrode. During heating, the electrode pores deposit molten silicon, causing the molten silicon to adhere to the electrode pore walls. This phenomenon easily causes a decrease in the insulating property of the electrode, thereby causing an arc discharge phenomenon, which may not only interrupt the production flow but also cause a failure operation of the functions of the equipment part, negatively affecting the high quality and efficient operation of the reduction furnace. Disclosure of utility model The electrode hole cleaning device aims at solving the technical problems that in the prior art, the electrode hole cleaning efficiency of a reducing furnace is low, the labor intensity is high, the electrode hole is not thoroughly cleaned, and the insulation performance of the electrode is possibly reduced. According to the application, a cleaning tool for electrode holes of a reduction furnace comprises: The cutting tooth structure is annularly arranged on the bottom end face of the rotary fixing part; The lower end of the supporting rod is fixedly connected to the rotary fixing part; the handheld part is connected to the upper end of the supporting rod. The rotary fixing part comprises a truncated cone, a fixing column and a disc-shaped structure, wherein the fixing column is fixed at the lower end of the supporting rod, the small end of the truncated cone is fixed at the lower end of the fixing column, and the tooth-shaped structure is fixed at the large end of the truncated cone. Further, the cutting tooth structure comprises a plurality of tooth-shaped structures, and all tooth-shaped structures are circumferentially arranged on the lower end face of the disc-shaped structure in an array mode. Further, the bottom surface of the tooth-shaped structure is an annular sector, one side of the tooth-shaped structure along the circumferential direction of the disc-shaped structure is smaller than the other side, and the high side of the tooth-shaped structure along the circumferential direction is provided with a cutting edge. Further, an end of the cutting edge near the inner side of the disc-shaped structure is lower than an end of the cutting edge near the outer side of the disc-shaped structure. Further, the rake face of the cutting edge is provided with an inclined chip surface. Further, a supporting surface is further arranged on one side, close to the adjacent tooth-shaped structure, of the front cutter surface. Further, the distance between every two tooth-shaped structures is 2cm. Compared with the prior art, the utility model has the beneficial effects that: Firstly, the utility model can rapidly and effectively remove the molten silicon attachments on the wall of the electrode hole by arranging the cutting tooth structure at the bottom of the disk-shaped structure, thereby obviously improving the cleaning efficiency. Secondly, the hand-held part is arranged on the supporting rod, so that an operator can easily control tools, physical consumption is reduced, and labor intensity is reduced.
