[0002] The raw material in our daily industry is called aluminum ingot. According to national standards, it should be called aluminum ingot for remelting, but everyone is used to calling it aluminum ingot. After aluminum ingot enters industrial application, there are two major categories: cast aluminum alloy and deformed aluminum alloy. Cast aluminum and aluminum alloy are aluminum castings produced by casting method, and deformed aluminum and aluminum alloy are aluminum processed products produced by pressure processing method: plates, strips, foils, tubes, rods, profiles, wires and forgings. In the production process of aluminum ingots, the aluminum liquid needs to be filtered and purified.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a liquid discharge cleaning mechanism, which is inflated by a pumping and charging dual-purpose air pump. Since the elastic force of the first spring is greater than the elastic force of the second spring, the gas first pushes the second piston, and the second piston drives the scraper to move to the right through the second movable rod, and then pushes the first piston, and the first piston drives the baffle to move to the left through the first movable rod. When the liquid hole moves through the bottom of the liquid inlet pipe, part of the aluminum liquid falls through the filter screen of the fixed plate for filtration and purification, and impurities remain on the surface of the filter screen. The baffle continues to move, and the liquid hole will continue to be blocked until the touch switch on the left outer wall of the baffle contacts the inner wall of the box body, and the liquid is discharged through the pumping and charging dual-purpose air pump. The air is extracted. Under the action of the first spring and the second spring, the bottom of the scraper moves to the left in contact with the filter screen, and the impurities on the surface of the filter screen are scraped to the left side of the filter screen. The baffle moves to the right and resets. In the process of moving to the right, the filter hole will overlap with the bottom of the liquid inlet pipe again, and the aluminum liquid will fall through the filter screen again until the touch switch on the right outer wall of the baffle contacts the end face of the first gas cylinder again, and the above action is repeated. Then the repeated action begins, and the scraper moves to the right to scrape the impurities on the filter screen after the second filtration in the last action to the fixed plate, thereby improving the filtration effect and cleaning the filter screen in time to avoid affecting the filtration of aluminum liquid.

[0025] Working principle: When using the aluminum liquid filtering and purification device for aluminum ingot production, first, the molten aluminum liquid is transported through the liquid inlet pipe 14, and the power of the device is turned on. Since the controller 13 is electrically connected to the dual-purpose air pump 31 and the touch switch 46 respectively, and the touch switch 46 located on the left side of the baffle 44 controls the dual-purpose air pump 31 to pump air, and the touch switch 46 located on the right side of the baffle 44 controls the dual-purpose air pump 31 to inflate;

[0026] In the initial state, since the touch switch 46 on the right side contacts the end of the first gas cylinder 4, the controller 13 enables the pumping and charging dual-purpose air pump 31 to inflate, and the pumping and charging dual-purpose air pump 31 delivers gas to the right side of the first piston 42 and the left side of the second piston 52 through the pipeline. Since the elastic force of the first spring 41 is greater than the elastic force of the second spring 51, the gas first pushes the second piston 52 to slide rightward in the second gas cylinder 5, and the second piston 52 squeezes the second spring 51, and the second piston 52 drives the scraper 54 to move to the right through the second movable rod 53.

The baffle plate 44 continues to move, and the liquid hole 45 continues to be blocked until the touch switch 46 on the left outer wall of the baffle plate 44 contacts the inner wall of the box body 1. The controller 13 controls the dual-purpose air pump 31 to pump air. After the gas filled in the first air cylinder 4 and the second air cylinder 5 is pumped away, under the action of the first spring 41 and the second spring 51, the bottom of the scraper 54 moves leftward in contact with the filter screen 21, and the filter screen is The impurities on the surface of the filter 21 are scraped to the left side of the filter 21, and the baffle 44 moves to the right to reset.
