Description

Technical Field

[0001] The utility model belongs to the field of metallurgy, and in particular relates to a melt conveying device. Background Art

[0002] During the production process of metallurgical furnaces, the intermediate melt needs to be discharged regularly. Currently, the discharge is mostly in the process of discharge port-chute-ladle. This discharge method causes the melt to continuously flush the ladle wall, leading to safety accidents such as ladle burning and melt overflow. At the same time, there is a lot of diffusion of toxic and harmful gases during the discharge process, which cannot be collected in time, endangering the health of workers and polluting the working environment. It is urgent to design a high-temperature melt diversion and splash prevention device that can solve the continuous flushing of the ladle by the high-temperature melt, and timely recover the flue gas in the discharge process to improve the on-site working environment. At the same time, the device must meet the requirements of simple structure and easy replacement and maintenance to meet the on-site production needs to the greatest extent. Utility Model Content

[0019] like Figures 1 to 7As shown, a high-temperature melt diversion and splash prevention device comprises a cylindrical shell 1, a feed pipe 2, a baffle 3, a smoke exhaust pipe 4, and an anti-splashing structure; the feed pipe 2 is arranged in the middle of the cylindrical shell 1 and passes through the cylindrical shell 1, the feed pipe 2 and the smoke exhaust pipe 4 are arranged axially staggered along the cylindrical shell 1, and the smoke exhaust pipe 4 is located above the feed pipe 2. The splash prevention structure comprises a semicircular cylinder 5, a bracket 6, and an arc-shaped baffle 7. The cylinder 5 is set to be semicircular, which ensures that the melt forms a passage through the feed pipe 2 and can also prevent the melt from splashing to the inner wall of the shell 1. The arc-shaped baffle 7 is connected to the inner wall of the semicircular cylinder 5 through four brackets 6 and is fixed in the form of bolt docking or quick connectors, so that the arc-shaped baffle 7 and the ramming material layer 8 can be disassembled or replaced. A ramming material layer 8 is provided on the inner surface of the arc baffle 7, which is resistant to high temperature and corrosion. The outlet of the feed pipe 2 faces the ramming material layer 8 on the arc baffle 7. Steel cat claws 9 are embedded in the arc baffle 7 and extend to the outside of the ramming material layer 8, which plays the role of gathering, draining and buffering the melt.

[0020] An observation port 10 is provided in the center of the baffle cover 3, which is made of explosion-proof, transparent and high-temperature resistant material. The flow direction and discharge of the high-temperature melt can be observed through the observation port 10, so that personnel can take corresponding measures more promptly; a positioning block 12 and a limiting boss 13 are provided on the lower side of the baffle cover 3, and a card slot 14 matching the positioning block 12 and the limiting boss 13 is provided on the top of the cylindrical shell 1. The cylindrical shell 1 is sleeved on the outside of the semicircular cylinder 5 and is clamped with the baffle cover 3 through the card slot; four lifting rings 11 are provided around the observation port 10 on the upper side of the baffle cover, and the anti-sputtering structure can be lifted out of the shell 1 through the lifting rings 11, so as to facilitate the maintenance and repair of the arc baffle 7 and the ramming material layer 8; the top of the semicircular cylinder 5 is welded on the limiting boss 13 on the lower side of the baffle cover 3, and the diameter of the semicircular cylinder 5 is smaller than the diameter of the cylindrical shell 1, so that a channel can be formed to facilitate the discharge of harmful gases.

[0021] The cylindrical shell 1, the baffle cover 3, and the anti-splashing structure are all hollow structures, and water pipes are arranged inside to cool the device. One water pipe is spirally coiled on the inner wall of the shell, enters from the top and flows out from the bottom. One end of the other water pipe enters from the A port on the baffle cover, enters the semicircular cylinder 5 through the B port, enters the arc partition 7 through the bracket 6, and then returns to the A port through another bracket 6 to flow out.

[0022] During operation, a ladle is placed directly below the arc baffle 7. After the high-temperature melt passes through the feed pipe 2, it is guided by the arc baffle 7 and falls into the center of the bottom of the ladle directly below the ladle. The smoke generated by the discharge of the high-temperature melt passes through the smoke exhaust pipe 4 on the upper part of the outer shell 1 and enters the annular collection system. The device is cooled by a connecting water pipe.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
