Feeding device for improving tailing processing capacity of thickener

The invention discloses a feeding device for improving the tailing processing capacity of a thickener, which comprises a buffer tank, and a feeding pipe, a forced dilution water feeding pipe for diluting tailing slurry and a feeding ring groove for conveying the diluted tailing slurry to the thickener which are respectively arranged on the buffer tank, a plurality of energy dissipation assemblies for reducing kinetic energy of the tailing slurry are arranged in the feeding ring groove, and a flocculant conveying pipe is arranged above the feeding ring groove. By controlling the included angle between an energy dissipation plate in the energy dissipation assembly and the horizontal direction, on one hand, the contact probability of tailings particles and a flocculant can be effectively increased by utilizing turbulent flow formed near the energy dissipation plate by collision of the tailings and the energy dissipation plate and combining and utilizing the multi-point adding design of the flocculant, so that th
