Full-automatic polishing machine for furnace drum

Abstract

The invention discloses a full-automatic polishing machine for a furnace drum. The full-automatic polishing machine comprises a base, a rotary working table, a lifting guide mechanism and a working mechanism, wherein the rotary working table is in a circular ring shape and is supported and fixed on the base through a plurality of support columns; the rotary working table is driven to rotate horizontally through a rotary driving device; the lifting guide mechanism comprises a lifting oil cylinder and a linear guide rail; and the working mechanism comprises a lifting platform, a fixed grinding and polishing machine head and a swing grinding and polishing machine head, the lifting platform is arranged on the linear guide rail in a sliding fit mode, the bottom of the lifting platform is connected with the output end of the lifting oil cylinder, and the fixed grinding and polishing machine head and the swing grinding and polishing machine head are installed on the left side and the right side of the lifting platform. The full-automatic polishing machine for the furnace drum is stable and reliable in structure and operation, is suitable for machining of drum type reaction furnaces, and is capable of avoiding grinding dead corners, and realizing three working procedures of grinding, mechanical polishing and electrochemical polishing through one-time hoisting.

Description

technical field [0001] The invention belongs to the technical field of polishing equipment, and in particular relates to a fully automatic furnace polishing machine. Background technique [0002] At present, the production of polysilicon adopts reduction technology, which is completed in a reduction furnace, and trichlorosilane is reduced by hydrogen to generate silicon and hydrogen chloride. During the reduction reaction, various impurities will be produced, especially carbon black, which is attached to the inner wall of the reduction furnace. On the one hand, it will pollute the inner wall of the mirror furnace, which originally has the function of heat reflection, so that the heat cannot be reflected and the heat energy is reduced. Utilization; On the other hand, impurities such as carbon black will also corrode the inner wall. Due to various problems in the production process, in order to improve production efficiency and reduce power consumption, after a period of prod...
