A fiber dispersion device for polypropylene fiber concrete
By combining the alternating rotation of the rotating shaft and the dispersing rod with the vibration of the elastic rope, the problem of uneven fiber dispersion in existing devices is solved, achieving uniform dispersion of polypropylene fibers and improving the performance of concrete.

AI Technical Summary
Existing polypropylene fiber dispersion devices have poor dispersion effects in non-intersection spaces, leading to severe fiber agglomeration and affecting concrete performance.
The design employs a rotating shaft, connecting rod, and dispersing rod rotating in an alternating manner, combined with the lifting and shaking of the elastic rope, to ensure uniform fiber dispersion through shearing and secondary dispersion.
This method achieves uniform dispersion of polypropylene fibers, avoids fiber agglomeration, and improves the flexural strength, crack resistance, and freeze-thaw resistance of concrete.
