Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot production, in particular to a scraping device for aluminum ingot production. Background Art

[0002] In the casting production of aluminum ingots, the heated molten aluminum needs to be poured into the mold and taken out after cooling. During the pouring and cooling, due to the rapid cooling speed of the surface, an oxide film is easily produced, which affects the quality of the aluminum ingot, so the oxide film needs to be removed in time.

[0003] The patent with the publication number CN211360578U discloses an oxide film removal device for aluminum ingot production, including a bottom plate, an aluminum ingot mold and a bracket, wherein the aluminum ingot mold is slidably arranged on the bottom plate, and the bracket is fixedly arranged on the bottom plate in cooperation with the aluminum ingot mold, and the bracket is provided with a translation mechanism, a slide plate is arranged on the translation mechanism, and a scraper is movably arranged on the slide plate; a baffle is arranged on the bracket in cooperation with the scraper; and hoppers are arranged on both sides of the aluminum ingot mold. The device drives the scraper to translate and scrape the oxide film by setting a translation mechanism, and then conveniently pours the oxide film into the hopper for recovery through the movably arranged scraper and the fixedly arranged baffle.

[0004] During the specific use of the above-mentioned prior art, when the scraper on the support rod one translates to the baffle rod, the scraper on the support rod one rotates around the hinge shaft due to the obstruction of the baffle rod, and the oxide film scraped off on the scraper needs to rely on its own weight to fall down into the hopper. However, there is a situation in which part of the oxide film cannot fall off during this process, resulting in part of the oxide film remaining on the scraper. When the scraper scrapes off the oxide film on the aluminum liquid next time, the oxide film remaining on the scraper may fall into the aluminum liquid, affecting the production quality of the aluminum ingot. In view of this, we propose a scraping device for aluminum ingot production. Utility Model Content
