Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis technology, and specifically relates to a device for cleaning anode carbon blocks and carbon bowls. Background Technology

[0002] In aluminum electrolysis production, the carbon bowl at the top of the replaced anode contains residual old pig iron, electrolyte, and carbon slag. Before recycling the residual anode and assembling a new anode, the carbon bowl must be thoroughly cleaned to ensure that the newly cast pig iron is tightly bonded to the carbon bowl body, guaranteeing conductivity and preventing increased energy consumption or "depolarization" accidents due to poor contact.

[0003] In existing technologies, cleaning the charcoal bowl mostly involves manual pneumatic hammering or simple robotic arm scraping. These cleaning methods suffer from high labor intensity, low efficiency, unstable cleaning quality, and easy damage to the charcoal bowl itself. Therefore, there is a need to provide a device for cleaning the anode charcoal bowl to solve the above-mentioned technical problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1-4 This embodiment provides the following technical solution: an anode carbon block and carbon bowl cleaning device, including a power source, a reduction gearbox and a cleaning head assembly. The power source is an electric motor, which drives the cleaning head assembly to work after the reduction gearbox reduces speed and increases torque.

[0016] The cleaning head assembly includes a main shaft 1, one end of which is connected to a gearbox for transmission, and the other end of the main shaft 1 is coaxially fixedly connected to a blade shaft 2. Multiple blades 3 are hinged to the side wall of the blade shaft 2. A blade holder 4 is fixedly connected to the end of the blade 3 away from the blade shaft 2 by bolts. A blade 5 is fixedly connected to the blade holder 4. The cleaning head assembly replaces the manual cleaning of the anode carbon block, improving cleaning efficiency and quality. Moreover, the blades 3, which swing around the shaft pin, achieve adaptive fitting of the blade 5 to the curved surface of the carbon cup, ensuring the cleaning effect.

[0017] The side wall of the blade shaft 2 is provided with a reserved hole corresponding to each blade 3. A shaft pin is fixedly connected in the reserved hole. The shaft pin is adapted to the hinge hole provided on the root of the blade 3. The hinge hole on the blade 3 is rotatably sleeved on the shaft pin, so that the blade 3 can rotate flexibly around the shaft pin. In some embodiments, a sliding bearing is installed in the hinge hole. The blade 3 is sleeved on the shaft pin through the sliding bearing to form a rotating pair, so that the blade 3 can rotate flexibly around the shaft pin.

[0018] The blade 3 is tilted in the direction of rotation of the blade shaft 2. In some embodiments, the tilt angle of the blade 3 is 5-15 degrees. This setting is conducive to the smooth opening of the blade 3 under the action of centrifugal force.

[0019] The surface of the blade 5 is coated with a wear-resistant coating. In some embodiments, the wear-resistant coating is a TiAlN coating, which improves the wear resistance of the blade 5.

[0020] It also includes a cutter head pressure plate 6, which is fitted onto the end of the cutter body shaft 2 away from the main shaft 1. The cutter head pressure plate 6 is fixedly connected to the main shaft 1. In some embodiments, the cutter head pressure plate 6 is fixedly connected to the end face of the main shaft 1 by bolts. Moreover, the cutter head pressure plate 6 is provided with an arc-shaped groove 7 corresponding to the swing trajectory of the blade 3. The inner end wall of the arc-shaped groove 7 is used to limit the maximum retraction angle of the blade 3, and the outer end wall of the arc-shaped groove 7 is used to limit the maximum opening angle of the blade 3.

[0021] It also includes a torsion spring, which is not shown in the diagram. The torsion spring is sleeved on the shaft pin. One end of the torsion spring is fixedly connected to the cutter shaft 2, and the other end of the torsion spring is fixedly connected to the blade 3, providing the blade 3 with a restoring torque that makes it tend to retract.

[0022] The working principle of this utility model is as follows: During operation, the power source drives the cleaning head assembly to rotate at high speed through the reduction gearbox. Under the action of centrifugal force, the blade 3 swings outward around the shaft pin, overcoming the resistance of the torsion spring, so that the blade 5 is in close contact with the inner wall of the carbon bowl. As the robotic arm device rotates and feeds, the blade 5 cleans the residue on the inner wall of the carbon bowl. When blade 5 wears, blade 3 will automatically adjust its opening angle to compensate for wear. After the work is completed, the rotation speed decreases, and under the action of the torsion spring, blade 3 retracts and returns to its initial position.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
