Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to an adjustable reflective peeping device for a blast furnace tuyere. Background Art

[0002] The blast furnace is a thermal device that provides hot air for the process and completes the combustion process and heat transfer process. The blast furnace operator will pay real-time attention to the working status of the blast furnace tuyere whirlpool zone, and use it as one of the important bases for judging and controlling the operation of the blast furnace. Usually, the blast furnace operator directly observes the internal situation of the blast furnace, the working condition of the tuyere and the furnace temperature trend from the tuyere peephole of the blast furnace, so as to feedback the operation status of the blast furnace, provide a basis for blast furnace adjustment, wide spraying and uniform spraying, and promote the long-term stable and smooth operation of the blast furnace.

[0003] At present, blast furnace operators use wind goggles to judge the combustion status of coal powder in the tuyere vortex zone based on the brightness of the tuyere. However, this method has the following defects: (1) the individual experience of operators varies greatly, and the accuracy of judgment is low; (2) the observation position is narrow and has great limitations, which makes it impossible for operators to observe closely; (3) the observation area is fixed and the angle cannot be adjusted, making it impossible to fully observe the combustion and coal injection of the blast furnace tuyere. Utility Model Content

[0004] The utility model provides an adjustable reflective peeping device for a blast furnace tuyere, which aims to facilitate operators to comprehensively observe the combustion and coal injection conditions of the blast furnace tuyere on a tuyere platform, thereby promoting the long-term stable and smooth operation of the blast furnace.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] An adjustable reflective peep device for a blast furnace tuyere comprises a peep tube, one end of the peep tube is communicated with a peep hole of the blast furnace tuyere, and the other end is connected to one end of a glass trough box, in which a transparent flat glass is embedded; the other end of the glass trough box is connected to an extension sleeve and a redirecting elbow in sequence, and a reflector is provided at the turning concave surface of the redirecting elbow.

[0007] Preferably, the redirecting elbow angle is adjustable.

[0008] Preferably, a valve is provided on the peep tube.

[0009] Preferably, the transparent flat glass is circular, and its outer diameter is larger than the outer diameter of the peep tube.

[0010] Preferably, the outer wall of the extension sleeve and the redirecting elbow is provided with a heat insulation box

[0011] Preferably, the insulation box is filled with insulation cotton.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. When the reflective peeping device provided by the utility model is used to observe the combustion and coal injection of the tuyere of the ironmaking blast furnace, the ironmaking workers can clearly observe the situation inside the tuyere on the tuyere platform. Moreover, the angle of the redirecting elbow is adjustable, which drives the angle of the reflector inside it to be adjustable accordingly. When the observation position is narrow and limited, and the personnel cannot observe closely, the angle of the redirecting elbow can be adjusted, and the internal situation of the tuyere can be observed from the side by combining the reflector, so as to intuitively and accurately feedback the operation status of the blast furnace, provide a basis for blast furnace adjustment, wide injection and uniform injection, and promote the long-term stable and smooth operation of the blast furnace.

[0014] 2. The reflective peeping device provided by the utility model has a valve on the peeping tube for cutting off the passage between the blast furnace blowpipe and the outside world. A transparent flat glass is embedded in the glass trough box as the terminal of the peeping tube to block the discharge of high-pressure hot air, and the situation inside the blowpipe can be observed through the transparent flat glass, which is safe and practical.

[0015] 3. The reflective peeping device provided by the utility model has an insulation box on the outer wall of the extension sleeve and the redirecting elbow, and the insulation box is filled with insulation cotton to protect the built-in reflector of the redirecting elbow from being damaged by high-temperature slag iron, thereby extending its service life and saving production costs.
