Description

Technical Field

[0001] The utility model belongs to the technical field of pulping pumping station equipment, and in particular relates to an underground pulping pumping station system. Background Art

[0002] Gangue slurry filling refers to the process of making gangue, water and additives into a slurry of a specific concentration by establishing a crushing station and a slurry pumping station, and then using a grouting pump to transport the gangue slurry to the underground filling point through a pipeline to achieve the purpose of treating gangue. At present, there are two types of slurry pumping station layouts, one is arranged at the ground industrial site or filling station, and the other is arranged at the underground pit yard or filling chamber. The slurry pumping station is arranged at the ground industrial site or filling station site to avoid the impact of site restrictions on the slurry pumping station, but the vertical riser slurry downhole and the long-distance pipeline transportation greatly increase the pipe blockage accidents of gangue slurry filling; the slurry pumping station is arranged at the underground pit yard or filling chamber to avoid the transportation problems and pipe blockage problems caused by long-distance pipeline transportation to a certain extent, but the size of the underground tunnel space greatly limits the layout of the slurry pumping station. In view of the advantages and problems of the above two modes, combined with the current on-site needs and development trends, it is necessary to develop an underground slurry pumping station system to reduce the impact of the size of the underground tunnel space on the layout of the slurry pumping station.

[0005] The utility model is also characterized in that:

[0007] The mixing unit comprises a pulping mixer, a feeding belt is connected with the pulping mixer, the pulping mixer is connected with a buffer mixer through a primary chute, and the buffer mixer is connected with a grouting filling pump through a secondary flow channel.

[0011] The beneficial effects of the utility model are:

[0012] The underground slurry pumping station system provided by the utility model, through the use of the first-level chute and the second-level chute, improves the large space occupation layout of the mixer and the grouting pump with a length of about 25-30m, a width of 3-5m, and a maximum height of 7.5-8.5m to a small space occupation layout with a length of about 18-22m, a width of 4.5-6m, and a maximum height of 6.4-7.0m, thereby reducing the amount of underground mine construction, reducing the impact of the underground tunnel space on the layout of the slurry pumping station, and improving the applicability of the underground slurry pumping station to the size of the underground tunnel.
