The invention discloses a large horizontal sand
silo suitable for combined filling of
mortar in dressing plants and dry
tailings in
tailings ponds. The sand
silo is characterized by being divided into a
mortar making region (I), a transport region (II) and a
tailings storage region (III), wherein ring-shaped high-pressure
water supply branch pipes (c) and high-pressure
gas supply branch pipes (a) are laid in the
mortar making region (I); high-pressure
water spray nozzles (d) are horizontally installed on the ring-shaped high-pressure
water supply branch pipes (c); high-pressure gas spray nozzles (b) are vertically installed on the high-pressure
gas supply branch pipes (a); high-pressure
water supply branch pipes (c) and high-pressure
gas supply branch pipes (a) are laid in the transport region (II) in parallel; high-pressure
water spray nozzles (d) are horizontally installed on the high-pressure water supply branch pipes (c); high-pressure gas spray nozzles (b) are vertically installed on the high-pressure gas supply branch pipes (a); the dip angle of the bottom plate of the horizontal sand
silo is 23-26 degrees; the length of the mortar making region (I) along the trend of the sand silo is 3-5 meters; the length of the transport region (II) along the trend of the sand silo is 5-8 meters; and the length of the tailings storage region (III) along the trend of the sand silo is 4-7 meters. The large horizontal sand silo is applied to mortar making, can be used for realizing high-capacity continuous filling, ensuring the quality of the fillers, shortening the unsupported roof time in the goafs, reducing the construction investment of the filling stations and ensuring mine mining and filling to achieve balance and is beneficial to realization of safety production and environmental friendliness of the mines.
