[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0024] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0025] like Figures 1 to 5 As shown, this utility model provides a device for cleaning a high-ash carbon powder layer on the surface of a residual electrode, including a cleaning drum 1. The cleaning drum 1 is divided into a cleaning section 101, a transition section 102, and a leakage section 103 along the material conveying direction, and is fixedly connected by bolts. The inlet end of the cleaning section 101 is connected to the feed chute 2, and the outlet end of the leakage section 103 is connected to the discharge chute 3. A driven gear 4 is fixedly sleeved on the outer circle of the cleaning section 101, and a drive gear 6 is sleeved on the output shaft of the drive motor 5, and the drive gear 6 meshes with the driven gear 4. The cleaning section 101 is equipped with at least two support rings 7 fixedly fitted on its outer circumference. The roller limiting assembly is connected to the support rings 7 to assist the rotation of the cleaning roller 1. The inner diameter of the transition section 102 gradually decreases from the inlet end to the outlet end. The inner wall of the cleaning section 101 is fixedly covered with several straight lining plates 104 and inclined lining plates 105. The material leakage section 103 is provided with several slag discharge holes 10301 distributed circumferentially. The ash and slag collection port 301 of the discharge chute 3 is located directly below the slag discharge holes 10301 in the material leakage section 103.

[0026] The cleaning section 101 and the material leakage section 103 are separated by the transition section 102, and the inner diameter of the transition section 102 gradually decreases from the inner diameter of the cleaning section 101 to the inner diameter of the material leakage section 103. The gradual decrease in the inner diameter of the transition section 102 helps the material to form a denser flow in the transition section 102, preventing the electrolyte and soft residual carbon powder in the material from being discharged from the end outlet of the material leakage section 103 along with the residual electrode under the action of the centrifugal force of the rotating cleaning drum 1.

[0027] Specifically, the straight lining plate 104 and the inclined lining plate 105 are arranged in cross, the straight lining plate 104 and the inclined lining plate 105 are both provided with a raised rib in the middle, and the straight lining plate 104 and the inclined lining plate 105 are provided with a damping rubber plate 106 on the inner wall of the cleaning section 101; since the straight lining plate 104 and the inclined lining plate 105 are both provided with a raised rib in the middle, when the cleaning roller 1 rotates, the cleaned residual pole and electrolyte mixture are turned over and impact and grind each other under the driving of the raised rib, and since the inclined lining plate 105 is inclined, the cleaned material moves towards the discharging direction; the damping rubber plate 106 between the straight lining plate 104 and the inclined lining plate 105 and the cleaning section 101 reduces the vibration and noise when the cleaning roller 1 works.

[0028] Specifically, the cleaning section 101 is provided with a dust baffle 8 and a sealing rubber flange 9 between the inlet end and the feeding chute 2; and the upper side of the discharging hole 10301 of the discharging section 103 is provided with a dust collecting cover 10. The dust baffle 8 and the sealing rubber flange 9 prevent dust from overflowing between the feeding chute 2 and the inlet end of the cleaning section 101, and the dust collecting cover 10 collects the dust coming out of the discharging hole 10301, effectively improving the working environment.

[0029] Specifically, the two supporting rings 7, the roller limiting assembly includes two stop wheels 11 and two supporting wheel sets, one supporting wheel set is arranged below each supporting ring 7, the one supporting wheel set includes two supporting wheels 12, the two supporting wheels 12 are arranged on the two sides of the lower part of the supporting ring 7 and abut against the supporting ring 7 to support the cleaning roller 1, the two stop wheels 11 abut against the end faces of the outer sides of the lower parts of the two supporting rings 7, and the axial direction of the stop wheel 11 is perpendicular to the axial direction of the supporting ring 7, and the stop wheel 11 and the supporting wheel 12 are both provided with a limiting adjusting bolt 13; the graphite block 14 for lubrication is arranged on the side surface of the supporting wheel 12, and the graphite block 14 for lubrication is in contact with the surface of the supporting wheel 12. The stop wheel 11 and the supporting wheel 12 are adjusted to the appropriate positions by adjusting the bolt 13, so that the top of each supporting wheel 12 is flush and in good contact with the surface of the supporting ring 7 on the cleaning section 101 to keep the center of the cleaning roller 1 horizontal, the stop wheel 11 is in good contact with the end face of the supporting ring 7 to limit the axial jumping of the cleaning roller 1, the graphite block 14 for lubrication is applied on the surface of the supporting wheel 12, and the supporting wheel 12 is in contact with the supporting ring 7, so that the surface of the supporting ring 7 is also attached with graphite, and the working wear of the contact surface is reduced by the lubricating effect of the graphite block for lubrication, thereby improving the service performance and the service life of the equipment.

[0030] In addition to the preferred embodiments described above, the utility model also has other implementation manners, and all other embodiments obtained by the person skilled in the art based on the embodiments in the utility model without creative labor belong to the range of the utility model claimed.
