Abstract

The invention relates to a corrugated pipe sealing device which comprises a stainless steel corrugated pipe. The stainless steel corrugated pipe is used for absorbing the axial amount of contraction. The upper end face and the lower end face of the stainless steel corrugated pipe are provided with flange plates correspondingly. The flange plate on the upper end face is connected with a feeding gate through a bolt, and the flange plate on the lower end face is connected with a weighing material tank through a bolt, so that a confined space allowing a blast furnace material to pass through is formed among the feeding gate, the stainless steel corrugated pipe and the weighing material tank. According to the corrugated pipe sealing device, a totally-enclosed-type structure with the machining flange corrugated pipe and a sealing ring are adopted, the sealing property of equipment is guaranteed, and dust leakage is prevented; by the adoption of the stainless steel corrugated pipe, the service life of the equipment is prolonged, and the equipment maintenance and replacement frequency is reduced; and during blast furnace operation, externally-connected compressed air can continuously purge a discharging outlet, dust congelation can be prevented, and equipment maintenance is facilitated.

Description

technical field [0001] The invention belongs to blast furnace bellless top equipment, in particular to a bellows sealing device. Background technique [0002] In blast furnace bellless top equipment, this kind of sealing device in the form of a bellows with purging function is used for the connection and dust-proof sealing between the charging gate and the weighing tank, and to absorb the axial shrinkage. The feeding gate is installed between the material receiving tank and the weighing material tank, and is used for opening and closing the discharge port of the material receiving tank. Usually, the connection and sealing between the loading gate and the weighing tank is carried out through components such as soft sealing tape and dust cover in the assembly of the loading gate. [0003] When the blast furnace is running, a large amount of dust is discharged between the charging gate and the weighing tank during each charging, pressure equalization and release process. The ...
