A vertical sand bin Fengshui two-stage time-sharing slurry making system around the wall and its application method

Abstract

The invention relates to an air and water two-stage time division wall surrounding mortar making system for a vertical sand silo and an application method of the air and water two-stage time division wall surrounding mortar making system for the vertical sand silo. The air and water two-stage time division wall surrounding mortar making system for the vertical sand silo comprises air pipes and high-pressure water pipes, wherein the air pipes are communicated with high-pressure air, the high-pressure water pipes are provided with spray nozzles, and the air pipes and the high-pressure water pipes are applied to high-pressure air mortar making and high-pressure water mortar making respectively. According to the invention, high-pressure air mortar making is only applied to loose mortar making before the vertical sand silo conducts sand release, high-pressure air mortar making stops in the sand release process, and abrasion of equipment and instruments and mortar making disturbance can be effectively avoided due to the fact that high-pressure air mortar making is mainly used before sand release is conducted and has an effect of loose mortar making. High-pressure water mortar making is adopted in the sand release process of the vertical sand silo, layered rotational flow can be formed by high-pressure water along the bottom of the sand silo, and stable sand release can be effectively implemented. The air and water two-stage time division wall surrounding mortar making system for the vertical sand silo and the application method of the air and water two-stage time division wall surrounding mortar making system for the vertical sand silo solve the problems that in terms of an existing mine vertical sand silo filling technology, technological parameters such as the made mortar density and the made mortar flow are unstable, the silo bottom can be easily hardened, and the concentration efficiency is low.

Description

technical field [0001] The present invention relates to the technical field of underground mining in non-coal mines, in particular to a slurry-making technology of a vertical sand bin, and more specifically to a vertical sand bin wind and water two-stage time-sharing slurry-making system around the wall and its use method, which is suitable for It is used in the stable and continuous preparation of high-concentration filling slurry with full tailings. Background technique [0002] The vertical sand bin filling system has the advantages of simple process flow, small investment and low operating cost, and is a form of filling system commonly used in mines at home and abroad. [0003] After decades of development, the vertical sand bin filling technology has made great progress, from graded tailings filling to full tailings filling, and the filling concentration has been further increased. However, due to insufficient understanding of the sand release mechanism of the vertical...
