Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a mixing feeding mechanism for processing black metal smelting and rolling products. Background Technique

[0002] Black metal smelting and rolling products refer to products obtained by smelting, casting or other processing techniques to roll black metal materials into different shapes. Black metals mainly refer to iron, manganese, chromium and their alloys, such as steel, pig iron, ferroalloy, cast iron, etc. During the processing of rolling products, a mixing feeding device is required to first mix the metal particle raw materials and then feed the raw materials through the device.

[0003] After retrieval, the utility model patent with the publication number CN218516499U discloses a mixing feeding mechanism for processing black metal smelting and rolling products. By installing a stirring barrel, a feeding hopper, a weighing sensor, a fixing plate, a solenoid valve and a feeding pipe, during the use of the mixing feeding mechanism, through the use of this device, it is convenient for workers to accurately proportion and weigh the input amount of metal raw materials at any time, thereby ensuring the quality of the processed rolling products.

[0004] Based on the above retrieval and combined with the existing technology, it is found that the processing of black metals will generate a large amount of dust and impurities, which are easy to accumulate inside the mechanism. Moreover, after mixing and feeding, there will be material residues on the inner wall of the mechanism, resulting in waste of raw materials and cross-contamination, and it is difficult to clean the inside of the mechanism, affecting the normal operation and service life of the equipment.
