Background
The blast furnace top charging bucket is a key device of a bell-less furnace top, and is characterized in that semi-clean gas or clean gas of a blast furnace is led to the furnace top charging bucket through a pressure equalizing pipeline, so that the pressure in the charging bucket is ensured to be equal to the furnace top pressure, a lower sealing valve is conveniently opened for discharging, and meanwhile, after the material distribution of the blast furnace is finished, the gas in the charging bucket is discharged to normal pressure through a pressure equalizing and discharging pipeline, so that an upper sealing valve is conveniently opened for charging the charging bucket with the charging burden of the receiving hopper. The charging bucket is eroded and corroded by the gas flow and the furnace burden for a long time, and the long-time lining plate is worn and corroded seriously, so that the blast furnace gas is leaked and the charging bucket is not pressurized. The gas leakage of the charging bucket causes gas poisoning of operators or the inability of feeding the blast furnace. The blast furnace can only repair welding the charging bucket through stopping production. The device is simple in manufacture and convenient to use in production, and avoids the shutdown of a blast furnace and the fire operation on a toxic and harmful pressure vessel, so that the device is a rapid and efficient practical device.
Disclosure of Invention
The utility model aims to provide a cross leakage plugging device for leakage plugging of a hole of a blast furnace material tank body, which aims to solve the problems that a charging bucket is subjected to flushing and corrosion of gas flow and furnace materials for a long time, the long-time lining plate is worn and corroded seriously to cause gas leakage of the blast furnace and the charging bucket is not pressure-maintaining, and the gas leakage of the charging bucket causes gas poisoning of operators or the blast furnace cannot feed.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a blast furnace charge jar body hole leakage shutoff cross type device that leaks, includes a style of calligraphy leak repairing bolt, be equipped with the screw rod on the style of calligraphy leak repairing bolt, the one end of screw rod is equipped with the rectangle and blocks the piece, the cover is equipped with a style of calligraphy leak repairing piece on the screw rod of style of calligraphy leak repairing bolt, a style of calligraphy leak repairing piece is close to a style of calligraphy leak repairing bolt's rectangle and blocks piece department, a style of calligraphy leak repairing bolt's screw rod other end is equipped with the nut, be equipped with the packing ring between a style of calligraphy leak repairing bolt's rectangle and the nut.
Preferably, an elastic gasket is arranged between the sealing rubber ring and the nut.
The beneficial effects of the utility model are as follows:
the cross type leakage repairing device for the leakage plugging of the hole of the blast furnace material tank body is characterized in that the cross type leakage repairing device is sleeved into another cross type device through a bolt before the leakage plugging of the hole of the material tank body, the cross type leakage repairing device is rotationally folded and overlapped into a cross type so as to extend into the hole of the material tank body, the cross type leakage repairing device is rotationally folded and overlapped into a cross type after extending into the hole of the material tank body so as to be convenient for double stress, a proper sealing rubber ring and an elastic gasket are sleeved at the bolt part, and the sealing plugging of the leakage part of the hole of the material tank body can be realized by tightening the nut.
