Description
Technical Field
[0001] The utility model relates to the technical field of mixers, and more specifically to a mixing mechanism for raw materials for brick production. Background Art
[0002] Brick is a traditional masonry material, which includes sand-lime brick, fly ash brick and many other types. For sand-lime brick, it is made of lime and quartz sand, sand or fine sandstone in appropriate proportions, which are ground, mixed with water, semi-dry pressed into shape and autoclaved for curing; while fly ash brick uses fly ash as the main raw material, mixed with cementing materials such as coal gangue powder or clay, and is made through batching, molding, drying and roasting, which can make full use of industrial waste and save fuel.
[0003] Before making the brick body, a mixer is needed to mix various manufacturing raw materials. For fly ash bricks, when mixing the raw materials, an appropriate amount of coal gangue powder is added to the fly ash and stirred. When adding the coal gangue powder, the coal gangue powder is generally added to the fly ash at one time. With such a adding method, the coal gangue powder will be too aggregated, which is not conducive to the full mixing of the coal gangue powder and the fly ash, resulting in a long mixing time and low mixing efficiency, which is not conducive to the rapid production of bricks. On the other hand, when the coal gangue powder is added, a small amount of stones will remain in the coal gangue powder. The current mixing mechanism lacks the function of removing stones, and these stones are mixed in the raw materials, which will affect the quality of the later formed bricks.
[0004] In view of this, the utility model proposes a mixing mechanism for raw materials for brick production to solve these problems. Summary of the invention
