Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis, and in particular to a cathode carbon block conveying and turning device for aluminum electrolysis. Background Technology

[0002] Cathode carbon blocks are a key material in electrolytic aluminum production, mainly used in the cathode section of electrolytic cells. They serve to conduct electricity, resist high-temperature corrosion, and support the cell lining. Aluminum cathode carbon blocks are a core material in electrolytic aluminum production, primarily used in the cathode section of electrolytic cells to provide conductivity, high-temperature resistance, and corrosion resistance. They are made from high-quality anthracite, petroleum coke, or graphite as aggregates and coal tar pitch as a binder, through processes such as crushing, kneading, molding, and calcination. They possess high conductivity, high-temperature resistance, and resistance to electrolyte erosion. Depending on the material, cathode carbon blocks can be divided into semi-graphite and fully graphite types. Semi-graphite blocks are less expensive and suitable for small and medium-sized electrolytic cells, while fully graphite blocks offer superior conductivity and corrosion resistance and are mostly used in large, high-efficiency cells. Furthermore, to improve performance, elements such as silicon and titanium are often added to enhance resistance to sodium expansion.

[0003] In the existing technology, when conveying cathode carbon blocks during the electrolytic aluminum production process, fixed conveyor belts, roller conveyors or hoisting equipment are usually used. However, the existing technology generally does not have an automatic turning function. Therefore, we need a cathode carbon block conveying and turning device for aluminum electrolysis.

[0023] The flipping device 6 includes a rotating shaft 601. Both ends of the rotating shaft 601 are rotatably connected to a bearing seat 602 via bearing assemblies. The bearing seat 602 is fixedly mounted on a support platform 4. One end of the rotating shaft 601 is poweredly connected to a flipping drive motor 603. Specifically, the rotating shaft 601 can be connected to the motor shaft of the flipping drive motor 603 via a coupling. The housing of the flipping drive motor 603 is mounted on the bearing seat 602. A flipping arm 604 is fixed to the rotating shaft 601. A bracket 605 is provided at the swing end of the flipping arm 604. The bracket 605 has two mutually perpendicular lifting surfaces 606, and a pushing assembly 7 is provided on the inner side of the lifting surfaces 606. The flipping drive motor 603 can drive the rotating shaft 601 to rotate, which in turn drives the bracket 605 to flip and rotate via the flipping arm 604, flipping the charcoal block onto the other side of the conveyor.

[0024] The sliding drive device 3 includes a first screw 301, which is arranged horizontally. One end of the first screw 301 is poweredly connected to the sliding drive motor 302. Specifically, the first screw 301 can be connected to the motor shaft of the sliding drive motor 302 through a coupling. The sliding drive motor 302 is mounted on the base 1.

A threaded sleeve 303 is connected to the first screw 301, and the threaded sleeve 303 is threadedly engaged with the first screw 301. The threaded sleeve 303 is fixed to the bottom of the moving platform 2.

[0025] The lifting device 5 includes a second screw 501, which is arranged vertically. The upper end of the second screw 501 is threadedly connected to a pre-reserved threaded hole on the support platform 4, and the lower end of the second screw 501 is poweredly connected to the lifting drive motor 502. Specifically, the second screw 501 can be connected to the motor shaft of the lifting drive motor 502 through a coupling. The lifting drive motor 502 is mounted on the moving platform 2.
