TECHNICAL FIELD
[0001] The utility model relates to a hose joint technical field especially relates to a blast furnace burns oxygen and prevents the off oxygen skin pipe clamp head. BACKGROUND
[0002] When the blast furnace iron tapping hole operation, the blast furnace normal opening is using the opening machine to drill through the iron tapping hole channel blocked with the clay, then the drill rod and drill bit of the opening machine are retreated, the slag iron flows out along the iron tapping hole channel, and the normal tapping is started. But in the process of opening the iron tapping hole, the iron tapping hole is drilled through, the slag iron penetrates into the gap between the iron tapping hole channel and the drill rod, and the drill rod is frozen, so that the drill rod cannot be pulled out, or the iron tapping hole channel is too hard or the opening machine fails, and the iron tapping hole cannot be opened by the opening machine, at this time, the iron tapping hole needs to be burned and opened by oxygen. Therefore, an oxygen source is usually arranged at a safety distance of 10 meters away from the iron tapping hole, and once these situations occur, the operator must quickly guide the oxygen source to the iron tapping hole area by a special skin pipe and tightly connect the oxygen skin pipe with the oxygen iron pipe used for burning the iron tapping hole. Then the post worker holds the oxygen iron pipe and burns and melts the residual drill rod, drill bit and slag iron frozen material in the iron tapping hole with oxygen, so that the iron tapping hole channel is connected with the inside of the furnace, and the tapping is started.
[0003] When the iron tapping hole is burned, the traditional method is to quickly put one end of the 10-30 meter special skin pipe on the seamless steel pipe of the oxygen source and the other end to the front of the iron tapping hole to be put on the oxygen iron pipe, and then oxygen is passed to burn the iron tapping hole. The oxygen flow through the skin pipe needs to be connected at two places, one is the connection between the seamless steel pipe of the oxygen source and the skin pipe, and the other is the connection between the skin pipe and the oxygen iron pipe. Burning the iron tapping hole is a remedial measure after the opening machine cannot be opened, and the time is very urgent. Under the traditional method, it is very difficult to connect the pipeline in a short time and burn the iron tapping hole. The inner diameter of the skin pipe is slightly smaller than the outer diameter of the hard pipe, and after insertion, it can be connected under the action of elasticity and friction, and will not fall off, so as to ensure the firmness of the connection. When connecting, the seamless steel and the oxygen iron pipe need to be inserted into the inside of the skin pipe more than 150mm. However, in the operation process, because the outer diameter of the hard pipe and the inner diameter of the skin pipe are close, it is very laborious and time-consuming to insert, and the insertion depth is difficult to guarantee more than 150mm, resulting in that when high-pressure oxygen is used to burn the iron tapping hole, the interface often collapses, causing the opening, and the safety accidents of the post worker being injured by the oxygen skin pipe and the backfire burn of the interface are prone to occur. Therefore, how to realize the quick and safe connection between the oxygen skin pipe and the hard pipe during the blast furnace iron tapping hole operation is a problem to be solved by the blast furnace technical personnel.
