Embodiment Construction
[0039] The blast furnace instrument automatic protection device 80 provided by the present invention is mainly used to protect the detection instrument 21 from the high temperature and dust in the blast furnace 60, and the instrument 21 can work normally even in the high temperature and heavy dust environment by cooling the temperature through the cooling gas. The blast furnace instrument automatic protection device 80 monitors the temperature and pressure in the blast furnace 60 in real time. When the temperature and pressure are normal, the blast furnace instrument automatic protection device 80 lowers the instrument 21 to the measurement position to measure the material level under the command of the software management platform. When the temperature or pressure is abnormal, the blast furnace instrument automatic protection device 80 will immediately lift the instrument 21 to the protective casing 40 for protection. It ensures the orderly and stable measurement of the detect...

The invention provides a blast furnace instrument protection device. The device comprises a base component, an instrument bin, a lifting mechanism, a protection sleeve and an electric valve. The base component comprises a base protection pipe and a base flange, one end of the base protection pipe is communicated with the blast furnace, the other end of the base protection pipe is connected with the base flange, and at least one first air inlet is formed in the base protection pipe. An instrument is arranged in the instrument bin, an exhaust hole is formed in the bottom of the instrument, and at least one second air inlet is formed in the top of the instrument. One end of the electric valve is connected with the base flange, and the other end is connected with one end of the protection sleeve. A flange cover is arranged at the top of the protection sleeve, at least one third air inlet is formed in the flange cover, and the second air inlet is connected with the third air inlet through an air pipe. The lifting mechanism comprises a fixing piece and a lifting piece, the fixing piece is installed above the flange cover, one end of the lifting piece is connected with the fixing piece, and the other end of the lifting piece penetrates through the flange cover to be connected with the top of the instrument bin. The device can be effectively protected under the severe conditions of the blast furnace, and the instrument can be conveniently repaired or maintained.
Description
technical field [0001] The invention relates to the technical field of blast furnace accessories, in particular to a blast furnace instrument protection device. Background technique [0002] The blast furnace is mainly used in the field of iron and steel smelting. The internal working environment of the blast furnace is extremely harsh: high temperature, high pressure, large dust, and high internal gas concentration contains adhesive tar. The instruments used to measure the internal data of the blast furnace (for example, 3D radar scanning Instruments) are easily damaged in such a harsh environment, affecting the smelting progress, and the operation of replacing or repairing these instruments is complicated and the workload is heavy. [0003] Therefore, a new instrument protection device is needed in the art to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of how ...
