Abstract
Description
Technical Field
[0001] The utility model relates to a steel fiber dispersing device, belonging to the field of steel fiber concrete production equipment and steel fiber transportation. Background Art
[0002] Concrete is a commonly used engineering composite material formed by mixing aggregate, cementitious material, water, admixtures and admixtures in a certain proportion. Adding an appropriate amount of fiber, especially steel fiber, to concrete can effectively inhibit the formation and development of micro cracks inside the concrete, improve its tensile and flexural strength, and greatly improve its toughness and impact strength. The steel fiber added to the concrete should be evenly dispersed to play a reinforcing role in the concrete. If the added steel fiber is unevenly dispersed, the concrete will lack steel fibers or steel fibers will agglomerate, which will not only have no reinforcing effect, but also cause local strength weakening.
[0003] Common steel fiber dispersion devices on the market are mostly vibration type or mechanical type. The vibration type uses a vibration motor to vibrate the feed, and the mechanical type uses a reduction motor to force the dispersion. The vibration type can better disperse the steel fibers than the mechanical type, and has less impact on the steel fiber material. The mechanical forced type can easily cause irregular bending of the steel fibers, affecting the performance. It is not common to set a dispersion device at the inlet where the steel fibers are fed into the mixing main machine. The impact of this on the agglomeration of steel fibers is crucial. An unreasonable structural setting can easily cause the already evenly dispersed steel fibers to clump together. Therefore, this application proposes a dispersion structure set at the end of the steel fiber conveying and metering device. Utility Model Content
