Blast-furnace tuyere observing device with adjustable spectroscope

Abstract

The invention discloses a blast-furnace tuyere observing device with an adjustable spectroscope. The observing device comprises a cylindrical connecting sleeve, a video camera and the spectroscope, wherein the cylindrical connecting sleeve is provided with a near end and a far end; the near end is matched with a peephole of a target; the video camera is arranged at one side of the cylindrical connecting sleeve; the spectroscope is arranged in the cylindrical connecting sleeve; and a longitudinal axis of the cylindrical connecting sleeve obliquely passes through the spectroscope, so that a part of light rays can pass through the spectroscope and directly reach the far end to form a first light path and the rest light rays can be reflected into the video camera by the spectroscope to form a second light path. By adopting the observing device, the internal condition of the object can be observed remotely by using the video camera and can be directly observed on site through naked eyes. Moreover, the observing device is very compact, so that precious operating space is saved. Furthermore, operating personnel can observe with naked eyes by directly standing in front of the observing device arranged horizontally, so that the defects of inconvenience in observing from a side face or the introduction of an additional reflecting mirror and the like are overcome.

Description

technical field [0001] The invention relates to an observation device for observing the internal conditions of a target object having a peep hole, such as a blast furnace. Background technique [0002] At present, the blast furnace is basically a "black box". Only through the peephole of the tuyere can the internal conditions of the blast furnace be directly observed, and the working condition of the tuyere and the trend of the furnace temperature can be observed. Blast furnace operators are very concerned about the working status of the blast furnace tuyere swirl area, and take it as one of the important basis for judging and controlling the blast furnace operating status. In the past, this work was done by artificial wind glasses. Operators use goggles to judge the combustion status of coal powder in the tuyere swirl area according to the brightness of the tuyere, and "peep" the delivery of coal powder from the tuyere. This method is discontinuous, and individual experien...

Problems solved by technology

But in this observation device, the naked eye observation port is on the side and the camera is on the front (relative to the longitudinal axis of the entire observation device), so that the whole device is not compact enough and it is slightly inconvenient to observe with the naked eye.

In addition, in this utility model patent application, it is not proposed to adjust the angle of the beam splitter or the beam splitting mirror to facilitate the observation of the internal conditions of the blast furnace in a wider range.
