Abstract

The invention relates to a sand silo used for backfilling a mine, and in particular relates to a vertical sand silo mud-making device. The vertical sand silo mud-making device comprises a silo body, wherein an annular mud-making pipe and two oblique mud-making pipes are arranged in the silo body; one end of the circular mud-making pipe is provided with a first high-pressure air pipe; upper ends of the two oblique mud-making pipes are both provided with second high-pressure air pipes; nozzles are evenly distributed in the annular mud-making pipe and the two oblique mud-making pipes; the nozzles comprise air inlet pipes and first jet pipes; the air inlet pipes are hollowed; the first jet pipes are sleeved on the air inlet pipes; rubber cushions are inset in the connection parts of the first jet pipes and the air inlet pipes; nozzle holes are formed in the central axes of the first jet pipes. The vertical sand silo mud-making device provided by the invention solves the problem that the nozzles are easy to block and damage when a vertical sand silo backfilling system releases mill tailings, has high sand-releasing concentration, and is stable.

Description

technical field [0001] The invention relates to a sand bin used in mine filling, in particular to a vertical sand bin slurry-making device. Background technique [0002] Since the 1970s, the vertical sand bin filling system has been popularized and applied in China. Since the tailing sand is deposited as saturated sand in the vertical sand bin, if it can flow out from the vertical sand discharge pipe, it must be carried out first. Make pulp and make it liquefied. During the tailing sand discharge process of the vertical sand bin filling system, it is easy to cause nozzle blockage and damage, and there are generally problems of low and unstable sand concentration, which greatly reduces the strength of the filling body. [0003] The vertical sand silo is a commonly used tailings storage facility for mine filling. The vertical sand silo system includes three subsystems: tailings slurry dehydration, storage and slurry feeding. Since the tailing sand settles into saturated sand...
