The oxide layer removing apparatus for recycling aluminum scrap according to claim 5, wherein: the glass box is characterized in that an observation window (16) is arranged at the position, close to the glass box (302), of the left side of the main box (1), and a material taking port (17) is arranged at the position, close to the collecting box (11), of the right side of the main box (1).
7. A method for implementing an apparatus for recovering aluminum scrap using the apparatus for removing an oxidized layer for recovering aluminum scrap according to claim 6, comprising the steps of:
s1, firstly, adding the waste aluminum materials into a crushing chamber (201) from a feed hopper (210) and dropping on a grid net (209) of a receiving table (208), then, opening a telescopic rod (202), driving a connecting frame (203) to move downwards by the telescopic rod (202), simultaneously, opening a driving motor (204), enabling the rotating rod (206) to rotate by the driving motor (204) through a transmission belt (205), gradually approaching a rotating cutting disc (207) to the waste aluminum materials on the grid net (209) along with the downward movement of the connecting frame (203), cutting the waste aluminum materials into small pieces, and enabling the small pieces to drop into a glass box (302) from the grid net (209);
s2, injecting a proper amount of hydrochloric acid solution through the liquid inlet pipe (308), enabling the hydrochloric acid to enter the glass box (302) to react with an oxide layer on the surface of the waste aluminum material firstly, observing the reaction condition in the glass box (302) through the observation window (16), starting the retractor (7) when bubbles are continuously generated in the glass box (302), winding the pull rope (8) through the retractor (7), enabling the filter cover (304) to ascend, enabling the aluminum material on the outer side of the filter cover (304) to ascend along with the aluminum material, and enabling the aluminum material to slide down onto the supporting plate (301) from the outer side of the filter cover (304) when the fixing ring (303) at the lower end of the filter cover (304) is flush with the opening at the upper end of the glass box (302).
S3, rolling the aluminum material along the inclined supporting plate (301) to the discharge port (10) and onto the filter screen (12) of the collecting box (11), opening the spray head (15), washing the aluminum material in a washing mode to wash away redundant hydrochloric acid and reduce the damage amount of aluminum, and finally taking out the collecting box (11) through the material taking port (17).
