Description

Technical Field

[0001] The invention belongs to the technical field of drying anode steel claws, and in particular relates to a method for improving the drying efficiency of anode steel claws. Background Art

[0002] During the assembly and production process of aluminum electrolytic anodes, the aluminum guide rod group dipped in graphite is used to dry the anode steel claws through a dryer to achieve the purpose of graphite adhesion treatment. Usually, small and medium-sized aluminum plants use dryers to directly dry the anode steel claws, but this drying method will cause the flame sprayed from the dryer nozzle to be used to dry the anode steel claws, and a considerable part of it will be sprayed around and on the top of the anode steel claws, resulting in low drying thermal efficiency, poor drying effect, long drying time, high natural gas consumption, and excessively high production costs, which in turn leads to low drying efficiency. At the same time, the direct drying method will also cause molten iron to splash and flames to rise, affecting safe production and posing safety risks and hidden dangers. Summary of the invention

[0003] The purpose of the present invention is to provide a method for improving the drying efficiency of anode steel claws, so as to solve the problem of low efficiency in the original drying of anode steel claws.

[0004] The technical solution of the present invention is: a method for improving the drying efficiency of anode steel claws, comprising the following steps: Step 1: Build two walls symmetrically and in parallel, set a dryer burner in the wall, the dryer burner is inclined and extends outward, and fireproof materials are arranged around the dryer burner; Step 2: The top and both ends of the wall are extended inwards respectively; Step 3: Set a steel plate on the top of the wall, set fireproof material between the steel plate and the wall, and place the anode steel claws between the two walls for drying.

[0005] As a further improvement of the present invention, in step one, the inclination angle of the dryer burner is 30°-45°.

[0006] As a further improvement of the present invention, in step 2, the extension distance of the top of the wall is 100-200 mm, and the extension distance of both ends of the wall is 100-200 mm.

[0007] As a further improvement of the present invention, in step three, the fireproof material is asbestos wool.

[0008] The beneficial effects of the present invention are as follows: By symmetrically and parallelly building two walls, the top of the wall extends inward for a certain distance to form an eaves effect, and the two ends of the wall extend inward for a certain distance to form a relatively closed space, thereby forming a cavity between the dryer burner and the anode steel claws, which can effectively gather the flame of the dryer burner to form a hot space, so that the anode steel claws in the two walls can be fully dried, the drying effect is more uniform, the drying time is reduced, and the natural gas consumption is effectively saved. At the same time, the flame will not run around, reducing safety risks and hidden dangers.

[0009] The use of brick walls for masonry has good load-bearing, thermal insulation, sound insulation, fire resistance and durability. The masonry strength is high, and thinner walls can be formed to reduce the floor space. The surface of the brick wall is usually delicate and smooth, and does not require too much post-decoration. It can meet different construction needs and is suitable for small and medium-sized aluminum plants to ensure production while having good economic benefits. In particular, the brick wall has good fireproof and heat-insulating properties, which can effectively delay the spread of fire and further improve the drying effect.

[0010] During the construction process, the dryer nozzle is wrapped with fireproof material, which can effectively prevent the surrounding heat from being transferred to the burner and effectively extend the life of the burner. The dryer burner is tilted toward the center, which is conducive to the heating of the flame and can drive the overflowing flame back to the center, gather the flame, improve the thermal efficiency, and further improve the drying efficiency.

[0011] The steel plate on the top of the brick wall can fix the frame and prevent the frame from deformation. Asbestos wool is used to fill the space between the top steel plate and the brick wall to ensure a tight seal. This will prevent the flame from reaching the bottom of the steel plate and the temperature of the bricks will not easily be transmitted to the steel plate, thereby ensuring the service life of the main components.

[0012] Asbestos wool is used as fireproof material. Asbestos wool has good tensile strength, good thermal insulation and corrosion resistance, and is not easy to burn. Therefore, it can reduce the surface temperature of steel plates, brick walls and burners, thereby reducing heat loss, saving fuel, further ensuring safe production and increasing the service life of components.

[0013] This method can effectively improve the drying efficiency of anode steel claws, significantly improve the efficiency of natural gas use, greatly reduce consumption, save energy consumption, and reduce production costs. It is suitable for the production needs of small and medium-sized aluminum plants, while reducing safety risks and hidden dangers, and effectively ensuring the effective operation of anode steel claw drying operations.
