Slurry return device capable of reducing flotation froth flushing water consumption

The utility model discloses a pulp return device capable of reducing the use amount of flotation foam flushing water. The pulp return device comprises a material receiving groove, a foam pool and a conveying device. The receiving tank is arranged at a discharge port of the flotation machine, the discharge port of the flotation machine scrapes foam out of the flotation machine through a foam scraper, the foam pool is arranged on the lower side of the receiving port, and the conveying device is connected with the foam pool; according to the scheme, the foam tank is vertically arranged below the discharge port, when the foam scraper scrapes ore-containing foam out of the flotation machine, under the action of gravity, all the ore-containing foam falls into the material receiving tank, water does not need to be adopted for auxiliary flowing in the process, all the collected ore-containing foam converges in the foam tank, and therefore the flotation efficiency is improved. The conveying device conveys ore-containi
