Detailed Description

Example 1

As shown in fig. 1 and 2, the lower plate surface 3 of the external lug 2 of the anode plate 1 is cut into a plane.

As the preferred scheme, the lower plate surfaces 3 on the external lugs 2 at the two ends of the upper edge of the anode plate 1 are coplanar.

The lower plate surface 3 is positioned in a horizontal plane vertical to the calibrating plumb surface of the anode plate 1. It should be noted here that, the plate surface warping deformation of the anode plate is difficult to avoid in the process of completing casting and transferring the anode plate 1 to the electrolytic plant, so the plate surface needs to be shaped before the electrolytic tank is installed, that is, before the electrolytic tank is installed, to eliminate the plate surface warping and deformation, so that the distance between the geometric center and the mass center of gravity can be ensured to be minimum when the anode plate is hung. The shaping process is carried out in a vertical state of the anode plate surface, and a reference surface used as calibration is positioned in a plumb bob surface, so that the calibrated reference surface is called a calibration plumb bob surface, the calibration plumb bob surface is used as a reference surface, the plate surface of the cut lower plate surface 3 is vertical to the calibration plumb bob surface, and the lower plate surface 3 of the external lifting lug 2 lapped on the conductive bar of the anode plate 1 is simultaneously positioned on a level surface with equal height.

When the anode plate 1 provided by the scheme is hung and placed, the included angle between the plate surface and the plumb bob surface is very small, almost the included angle can be ignored, the plate surface of the anode plate is considered to be inosculated with the plumb bob surface, the arrangement of the anode plate at even intervals provides guarantee, and the manual operation for implementing complex adjustment is not needed.

The cutting range of the lower plate surface 3 of the external lifting lug 2, which is a plane, is 30-60 mm from outside to inside. That is to say, the local area of the outermost side of the lower plate surface 3 of the external lug 2 needs to be cut into a plane, because the cutting range of the external lug 2 from the outer end to the outside to the inside is 30-60 mm, the local area can meet the lap joint fit with the conducting bar, and even if the anode plate slightly deviates in the tank width direction of the electrolytic tank, the reliable electric contact fit can be met, and the cutting workload can be reduced.

The scheme can completely ensure the precision of the cutting surface of the lower plate surface 3 of the external lifting lug 2 of the anode plate 1, and can also obviously reduce the vibration phenomenon during cutting, so that the blade breakage phenomenon is minimized. The above-mentioned scheme can be understood from the following scheme that the finally-formed cutters 30 are independently arranged in the circumferential direction and the axial direction, the cutters 30 adjacent to each other on the left and right in the axial direction are arranged at intervals and are also staggered in the circumferential direction, and the cutters 30 adjacent to each other on the front and back in the circumferential direction are also staggered in the axial direction, and it is emphasized that the cutting trajectories of the cutting edges of all the cutters 30 are complete and continuous planes, and the processing difficulty is simplified by adopting the structure shown in the figure while the functional requirements are met.
