Description

TECHNICAL FIELD

[0001] The application relates to the technical field of refractory material processing and preparation, in particular to a preparation device and method of aluminum silicon carbide carbon bricks for a ladle. BACKGROUND

[0002] The ladle is an important container for containing and transporting high-temperature molten iron in the steel smelting process, and the performance of the lining refractory material thereof directly affects the service life and safety of the ladle. Common lining refractory materials of the ladle include high-alumina bricks, magnesia-carbon bricks, aluminum silicon carbide carbon bricks and the like. In recent years, the aluminum silicon carbide carbon brick has been widely used in the lining of the ladle due to its good high-temperature strength, strong corrosion resistance and excellent thermal shock stability.

[0003] After searching, it is found that the existing technology with the publication number CN221847034U discloses a raw material mixing device for aluminum silicon carbide carbon brick production. The technical problem is that the traditional raw material mixing device for aluminum silicon carbide carbon brick production is mostly single-stirring mixed during the mixing process. If the stirring and mixing are not fully completed, manual handling is required, and the raw material mixing needs to be mixed multiple times until the mixing is fully completed, which causes time cost waste. The scheme sets up a support assembly to support the device, a small mixing tank assembly and a large mixing tank assembly are used for stirring and mixing, a blocking assembly is used to make the particles stay for sufficient stirring, and a vibration assembly is used to shake out qualified particles.

[0004] Therefore, based on the above search and in combination with the existing technology, the powdery raw materials usually rely on gravity to directly fall into the mixing cylinder in the feeding hopper. Due to the lack of a structure similar to the spoiler in the water gun nozzle, the raw materials are difficult to be effectively dispersed during the falling process, and the concentrated flow and deflected flow phenomenon is easy to occur, which not only causes uneven distribution of different component powders when entering the mixing cylinder, but also causes further stratification of the raw materials under the action of gravity due to the difference in particle size or density, thereby reducing the mixing effect, and finally in the subsequent calcination process, the semi-finished aluminum silicon carbide brick is prone to structural stratification and insufficient strength and the like. Therefore, the application provides a preparation device and method of aluminum silicon carbide carbon bricks for a ladle. SUMMARY

[0024] The working principle of the present application is as follows: In use, the sliding tray 2 drives the feeding surface shell 3 to move, so that the feeding hopper 201 is located above the mold box 15, then the wheel hub motor 107 drives the transmission belt 106 to rotate, so that the aluminum silicon carbide brick raw materials are transmitted to the inside of the feeding hopper 201 through the transmission belt 106, at the same time, the gas flowing in the air pipe 103 is divided by the two shunt pipes 105, then the gas flows out from the output end of the shunt pipe 105, and the air pressure difference generated by the airflow reduces the pressure in the feeding hopper 201, so that the raw materials are sprayed out under the action of the pressure difference, and the aluminum silicon carbide brick raw materials are conveyed to the above of the feeding hopper 201 through the transmission belt 106, then fall into the hopper under the action of gravity, and then are sprayed out by the airflow, which can effectively avoid the blockage of the raw materials in the feeding hopper 201; At this time, the graphite has flowed into the inside of the mixing cylinder 203 through the fusion pipe 104, and flows into the inside of the storage groove on the outer surface of the shunt cylinder 204, and waits to be pushed out; In the process of gas flowing in the shunt pipe 105, the vortex fan 306 is driven to rotate, then the vortex fan 306 drives the driving plate 302 to rotate through the driving ring 305, so that the driving plate 302 drives the extrusion wheel 304 to move, and starts to extrude the air in the air bag 308, then the extruded air flows through the inside of the output pipe 208, then the output pipe 208 inputs the air into the inside of the lifting pipe 207 after the extrusion wheel 304 passes, so that the lifting pipe 207 moves upward, and the pushing rod 206 pushes the pushing plate 205 to move away from the lifting pipe 207, so as to realize the pushing out of the graphite in the storage groove on the outer surface of the shunt cylinder 204, the mixing with other raw materials in the inside of the feeding hopper 201, and finally falling into the inside of the mold box 15; At this time, the air pipe 103 stops supplying air, at this time, the additives and the binding agent stop being supplied, at this time, the lifting pipe 207 falls under the action of gravity, the air is input back into the inside of the air bag 308 through the output pipe 208, then the sliding tray 2 drives the feeding hopper 201 to move, then the sealing cover 17 is closed, and the aluminum silicon carbide brick raw materials are extruded into semi-finished products.

[0025] Then the semi-finished aluminum silicon carbide brick is taken out, and then the next feeding step of the semi-finished brick production is carried out.
