SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned shortcomings of the prior art, the present invention is directed to a fluidized device for feeding molten iron desulphurization to prolong the service life of the fluidized device.
In order to realize the above-mentioned purpose and other relevant purposes, the utility model provides a molten iron desulfurization feed fluidization device, including the feed tank, the intercommunication has charge-in pipeline and ejection of compact pipeline on the feed tank, feed tank bottom intercommunication has the pipeline of blowing of helping, it is provided with the bearing component that can breathe freely to help the intercommunication position between pipeline and the feed tank of blowing.
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.

Fig. 1 is a schematic structural diagram of a fluidized feeding device for desulfurizing molten iron according to an embodiment of the present invention.
Fig. 2 is an enlarged view of a point a in fig. 1.
Detailed Description
Reference numerals in the drawings of the specification include: the device comprises a feeding tank 1, a mounting seat 2, a breathable felt 3, a breathable screen 4, a valve 5, a feeding pipeline 6, a discharging pipeline 7, a first blowing-assisting pipeline 8 and a second blowing-assisting pipeline 9.
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Examples
As shown in fig. 1 and 2, the present embodiment provides a molten iron desulfurization feeding fluidization device, which includes a feeding bucket 1, wherein the top of the feeding bucket 1 is semicircular, and the bottom of the feeding bucket 1 is funnel-shaped. Feed tank 1 top intermediate position intercommunication has charge-in pipeline 6, is provided with valve 5 on charge-in pipeline 6, and valve 5 adopts the cone valve in this embodiment, because big end down in the cone valve internal channel, can effectually guarantee that the feeding is unblocked, is difficult for blockking up.
The feeding tank 1 beside the feeding pipeline 6 is communicated with a discharging pipeline 7, one end of the discharging pipeline 7 is communicated with the feeding tank 1, and the other end of the discharging pipeline 7 is communicated with a molten iron tank to be processed. The discharge pipe 7 is arranged obliquely upwards so that the fluidized mixed gas can be discharged from the discharge pipe 7. The lowest position of the bottom of the feeding tank 1 is fixedly provided with a mounting seat 2, a first blowing assisting pipeline 8 and a second blowing assisting pipeline 9 are fixedly arranged on the mounting seat 2, and the first blowing assisting pipeline 8 and the second blowing assisting pipeline 9 are communicated with the inner space of the feeding tank 1. The installation seat 2 is internally provided with a breathable felt 3 and a breathable screen 4, the breathable screen 4 is arranged below the breathable felt 3, the breathable screen 4 and the breathable felt 3 are both fixed on the installation seat 2, the breathable screen 4 and the breathable felt 3 are arranged between the communication positions of the first blowing-assisting pipeline 8, the second blowing-assisting pipeline 9 and the feeding tank 1, and nitrogen blown from the first blowing-assisting pipeline 8 and the second blowing-assisting pipeline 9 enters the feeding tank 1 after passing through the breathable screen 4 and the breathable felt 3.
