Further, the feed tank top is the semicircle form, the feed tank bottom is the funnel shape, charge-in pipeline and ejection of compact pipeline all set up on the semicircle of feed tank.
Further, the discharge pipeline is arranged in an upward inclined mode.
Further, the blow-assisting pipeline comprises a first blow-assisting pipeline and a second blow-assisting pipeline.
Further, the load bearing assembly includes an air permeable felt and an air permeable screen.
Further, the air-permeable felt and the air-permeable screen are arranged in an overlapping manner.
Further, the lowest position of the bottom end of the feeding tank is provided with a mounting seat, and the bearing assembly is installed in the mounting seat.
Further, a cone valve is arranged on the feeding pipeline.
Further, one end of the discharge pipeline is communicated with the feeding tank, and the other end of the discharge pipeline is communicated with the hot metal ladle.
As mentioned above, the utility model discloses a molten iron desulfurization feed fluidization device has following beneficial effect:
due to the arrangement of the feeding pipeline, the powdery desulfurizer can conveniently enter the feeding tank.
Due to the arrangement of the gas-assisted pipeline, the powdery desulfurizer is fluidized conveniently.
Due to the arrangement of the discharge pipeline, the fluidized desulfurizer can be conveniently discharged from the discharge pipeline.
Because the bearing assembly plays the bearing effect, still have the air permeability simultaneously for nitrogen gas that gets into from helping the gas pipeline can pass through smoothly, satisfies the air permeability and satisfies the bearing performance simultaneously. Effectively prolonging the service life of the molten steel desulfurization feeding fluidization device.
The scheme realizes the fluidization of the molten steel vulcanization feeding.
