Description

Technical Field

[0001] The utility model relates to the technical field of calcining devices, in particular to a production raw material calcining device. Background Art

[0002] Aluminum ingot is a raw material used to produce aluminum products. It is lightweight, corrosion-resistant and has good thermal conductivity. It is widely used in aerospace, automobile manufacturing, construction and other fields. In the production process of aluminum ingots, calcination is an indispensable step. The raw materials usually contain moisture and organic matter, which can be removed by calcination to avoid the generation of bubbles and impurities in the subsequent smelting process.

[0003] Patent publication number CN115560607A is a device for calcining raw materials for aluminum ingot production. It puts a container with raw materials for aluminum ingot production into a calcining furnace for calcining. After calcination is completed, the cover plate slides forward and contacts the arc scraper. The condensate adhered to the lower side of the cover plate is scraped off by the arc scraper, and the annular scraper ring moves upward to scrape off the condensate adhered to the inner wall of the calcining furnace, so as to avoid affecting the next heating effect and affecting the quality of the aluminum ingot.

[0004] However, the calcination devices with the above-mentioned and similar working principles have the problem of low calcination efficiency. In actual use, the volume of raw materials varies, and the time required for calcination varies with the volume. The above-mentioned calcination device does not have a mechanism for crushing the raw materials. In order to ensure that the raw materials are fully calcined, the calcination time will be based on the calcination time of the largest volume raw material block in the raw materials, and thus the calcination time for this batch of raw materials will be longer. When the raw materials are put into the calcining furnace, the raw materials will be accumulated at the bottom of the calcining furnace due to gravity. In the prior art, simple stirring is usually used to ensure that the raw materials are heated evenly, but simple stirring cannot well transfer the position of the raw materials accumulated at the bottom of the calcining furnace, and thus the raw materials are heated unevenly, resulting in low calcination efficiency.
