Viewing device for polysilicon furnace

Abstract

The invention pertains to an observing device of a polysilicon furnace. The observing device is arranged on the base of the viewing port of a furnace body and consists of a base, a bearing, an electric-control motor, a conveyor belt, a rotary shaft, a rotating seat, an infrared thermo detector probe, a camera and a viewport observing mirror, wherein, the base, one end of which is fixedly providedwith the electric-control motor, is fixedly connected on the base of the viewing port of the furnace body; the electric-control motor drives a motor wheel and a shaft wheel which is coaxial with the rotary shaft by the conveyor belt; the lower end of the shaft wheel is connected with the base by the bearing while the upper end of the shaft wheel is provided with the rotating saddle, on which the infrared thermo detector probe, the camera and the viewport observing mirror are arranged. Since the observing device is arranged on the base of the viewing port of the furnace body and the situation in the furnace body can observed on an operating worktable all the time, the safety of operators can be guaranteed and the observation is accurate and comprehensive with time and labor saved; in addition, the observing device has the advantages of simple structure, low manufacturing cost, convenient use and good effects.

Description

technical field [0001] The invention belongs to a polysilicon furnace observation device. Background technique [0002] At present, during the production of polysilicon furnaces, in order to maintain the high temperature and high pressure in the furnace body, the furnace body is required to be well sealed, so only one observation window is set at the upper end of the furnace body. When producing silicon ingots, the traditional observation methods are all carried out manually, that is, the operator uses visual inspection outside the observation window or carries an infrared temperature measurement device. Since the upper end of the furnace body is equipped with a heating element in addition to the observation window located in the center of the top Each high-voltage power supply connector and the wire connector and electrical box of each controller. Therefore, it is very dangerous for operators to observe and operate in this environment, and electric shocks occur from time t...

Problems solved by technology

Therefore, it is very dangerous for operators to observe and operate in this environment, and electric shocks occur from time to time, which cannot guarantee the safety of operators. To know and grasp the production situation of silicon ingots inside the furnace body in time, one must repeatedly climb to the top of the furnace body for observation, which is time-consuming, laborious, and very dangerous, and it is impossible to keep abreast of the situation in the furnace body. Daily work brings great inconvenience
