Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, and in particular to an automatic material loosening device for sintering machines to prevent material sticking. Background Technology

[0002] The loosening device is an important piece of equipment for improving the air permeability of the mixture during the sintering process. Its main function is to create regular pores in the cross-section of the sintering material layer through steel pipes, reducing the air resistance of the material layer and increasing the effective air volume, thereby improving airflow distribution and increasing the air permeability of the material layer. However, existing loosening devices are prone to material adhesion during use and are difficult to clean. After a period of use, this can lead to uneven distribution of the sintering mixture, uneven material distribution, and poor air permeability, resulting in reduced sintering machine capacity and a corresponding deterioration in the particle size of the finished sinter. To avoid these problems, the sintering machine needs to be stopped periodically for manual cleaning of the loosening device, affecting the stable and continuous production of the sintering machine. During long-term contact with the material, the loosening rods are prone to caking. Currently, most methods rely on manual cleaning of the loosening rods, which is inefficient and labor-intensive. When using multiple layers of loosening rods, the bottom rods are impossible to clean due to their overlapping. Utility Model Content
