Description
Technical Field
The utility model relates to an online blowing device for a blast furnace tuyere peephole.
Background
Blast furnace tuyere peep hole is the observation hole of installing the direct observation blast furnace internal behavior on blast furnace tuyere device, and the peep hole is equipped with clear glass and cuts off the valve, makes things convenient for the operating personnel to clear up stained glass, often meets special operation during the blast furnace, and coke can flow backward to peep hole valve front end in the blast furnace, and this kind of the coke degree of difficulty that flows backward of clearance on line is very big, and operating personnel safety risk is also very big, consequently needs a novel convenient and reliable's online cleaning device.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides an online blowing device for a blast furnace tuyere peephole, which solves the problem that the front end of a blast furnace tuyere peephole valve is difficult to clean online after coke is poured backwards, and simultaneously reduces the discharge of high-temperature gas and high-temperature slag powder and ensures the safety of operating personnel.
The technical scheme of the utility model for solving the technical problems is as follows: the utility model provides a blast furnace tuyere peephole sweeps device on line, includes connecting pipe, flange, observation window, sweeps high-pressure pipe and sweeps the air supply connecting pipe one end is provided with flange to through this flange and blast furnace tuyere peephole fixed connection the connecting pipe other end with observation window fixed connection, be provided with the high-pressure pipe that sweeps who is linked together rather than on the connecting pipe, should sweep the high-pressure pipe and be connected through the gas outlet of hose and sweep the air supply.
The utility model further defines the technical scheme as follows:
preferably, a shut-off valve is arranged on the connecting pipe, and the shut-off valve is positioned at the rear end of the purging high-pressure pipe.
Preferably, the purge high-pressure pipe is provided with a purge cut-off valve.
Preferably, threaded connectors are respectively arranged at two ends of the hose and are respectively connected with the purging high-pressure pipe and the gas outlet of the purging gas source through the threaded connectors, so that the purging tightness is guaranteed.
Preferably, a connecting portion is arranged on one side of the observation window, an external thread is arranged outside the connecting portion, the observation window is in threaded connection with an internal thread hole formed in the other end of the connecting pipe through the external thread on the outside of the connecting portion, and the observation window is convenient to detach and mount.
