The cyclone bottom-flow energy dissipation device in the graded tailing filling system comprises a cyclone, a material guiding pipe, a stereo tailing bin and an energy dissipation device body; the material guiding pipe comprises a material guiding pipe first end and a material guiding pipe second end; the material guiding pipe first end is fixedly connected with the bottomend of the cyclone, the material guiding pipe second end is connected with an inlet of the energy dissipation device body and arranged in a stereo tailing bin feeding region; and the energy dissipation device body is arranged on the lower portion of the cyclone, arranged in the stereo tailing bin feeding region and fixedly connected with the material guiding pipe second end. According to the cyclone bottom-flow energy dissipation device in the graded tailings filling system and the energy dissipation method thereof, impact and disturbance of the bottom flow of the cyclone on the liquid level of the tailing bin can be eliminated significantly, the settlement environment and the concentration effect of graded tailings in the tailing bin are improved, the stability of the bottom flow concentration of the tailing bin is improved, and the filling quality is ensured.

Description

technical field [0001] The invention relates to the technical field of graded tailings cemented filling, in particular to a cyclone underflow energy dissipator and an energy dissipation method in a graded tailings filling system. Background technique [0002] The graded tailings cemented filling technology has become an important part of today’s filling mining method. The realization of the graded tailings cemented filling process mainly includes four key processes: 1. Tailings classification, 2. Tailings dehydration, 3. Filling slurry preparation , 4, filling slurry delivery. [0003] At present, the mature process commonly used in mines is as follows: [0004] The whole tailing mortar of the mine concentrator is transported to the cyclone on the top of the sand bin through the slurry pump through the pipeline. [0005] After the full-tailed mortar is classified by the cyclone, the coarse-tailed mortar is directly put into the sand bin to settle naturally, and the fine-ta...
