8. A method for aluminum smelting slag treatment according to any one of claims 1 to 7, characterized in that: The processing method comprises the following steps: Step 1: Select the cleaning target, which is the aluminum liquid surface and the furnace bottom. Select the corresponding slag bucket according to the cleaning target; When slagging the aluminum liquid level of the smelting furnace, the narrow-distance slag bucket (32) is rotated so that the narrow-distance slag bucket (32) is flush with the telescopic support (23); When the slag remaining at the bottom of the smelting furnace is being slag-removed, the narrow-spacing slag bucket (32) is rotated so that the narrow-spacing slag bucket (32) is flush with the wide-spacing slag bucket (31); Step 2: According to the size of the slag bucket, the plane in the smelting furnace is divided into multiple cleaning areas of the same width, which are defined as a slag removal path. The slag removal module performs a slag removal process in sequence according to the cleaning area; Step 3: Obtain the slag plane image after the slag removal process, and pre-process the slag plane image; the slag plane image pre-processing is to normalize and denoise the image; Step 4: Use the Canny algorithm to identify the contour and edge area features of the scum in the preprocessed image, and use the convolutional neural network to generate a scum heat map; Step 5: Use clustering algorithm to cluster the generated slag heat map and identify the concentrated area of slag; Step 6: Determine the data and type of the slag volume in each area according to the clustering results, and perform slag removal on the remaining slag in turn through the slag removal module; Step 7: Collect the slag plane image again through the data acquisition module and calculate the total amount of slag residue, compare the total amount of slag residue with the preset slag residue standard amount, when the total amount of slag residue is greater than the slag residue standard amount, repeat steps 3 to 6, when the total amount of slag residue is less than or equal to the slag residue standard amount, the slag removal operation is completed.
