Technical Field

[0001] The utility model relates to the technical field of waste aluminum smelting, in particular to a dust cover for an aluminum liquid flow trough. Background Art

[0002] At present, the dust covers for aluminum troughs on various melting and casting machines are not uniform. Before each casting or after the casting, the dust covers on the aluminum troughs need to be manually removed, and sometimes the dust covers are missing. First of all, the temperature of the dust covers removed after the casting is relatively high, and manual operation poses a safety hazard. After the dust covers are missing, external dust, aluminum pins and other debris can easily enter the aluminum in the aluminum trough, causing secondary pollution of the aluminum, and also bringing hidden dangers to the quality of subsequent ingots.

[0023] The sealing assembly includes a sealing ring 3, a second cylinder 4 and a suction cup 5. The sealing ring 3 is arranged on the cover body 1 (the bottom of the cover body 1) and is located between the cover body 1 and the top wall of the aluminum liquid flow groove 9. The notch is located on the inner side of the sealing ring 3. The second cylinder 4 is arranged on the cover body 1 (the bottom of the cover body 1). The second cylinder 4 is fixedly connected to the suction cup 5, and the suction cup 5 faces the top wall of the aluminum liquid flow groove 9.

[0024] When in use, the dust cover of this embodiment covers the notch of the aluminum liquid flow groove 9 or opens the notch. Specifically, the first cylinder 22 is started, driving the transmission rod 21 to move, and then driving the cover body 1 to rotate, so that the cover body 1 covers the notch or opens the notch. At the same time, the second cylinder 4 is started, and the suction cup 5 acts, and the suction cup 5 sucks or releases the top wall of the aluminum liquid flow groove 9; after the suction cup 5 sucks the top wall of the aluminum liquid flow groove 9, the cover body 1 can further stably cover the aluminum liquid flow groove 9.

[0025] At the same time, the sealing ring 3 seals the gap between the cover body 1 and the top wall of the aluminum liquid flow groove 9. The notch is located on the inner side of the sealing ring 3, and external dust, aluminum pins and other debris cannot enter the aluminum liquid flow groove 9 through the above gap, effectively avoiding secondary contamination of the aluminum liquid.
