Described feeding warehouse comprises cylinder, and the lower end of cylinder connects the circular cone bucket of convergent.
Described rotary feeder comprises and the vertically arranged columniform housing of described feeding warehouse, the longitudinal center line of its longitudinal center line and described feeding warehouse is coplanar, there are the dried tailings import that is communicated with described circular cone bucket, the dried tailings outlet that the lower end has to be communicated with described ejector in the upper end, periphery middle part of housing, dried tailings import is the horn mouth of convergent, and dried tailings outlet is the straight tube mouth; Rotatable impeller is arranged in the housing, and the central axis two ends of impeller are fixed on the housing, and the longitudinal center line of central axis overlaps with the longitudinal center line of housing.
Described ejector comprises spray chamber, and described charging aperture, air intake, discharging opening lay respectively at upper end, left end and the right-hand member of spray chamber; There is nozzle at air intake place in the spray chamber, and charging aperture is positioned at the back upper place of air intake, with the angle of air intake be acute angle, the end of nozzle is positioned at the bottom of charging aperture, discharging opening and air intake, nozzle are coaxial to center line, are the horn mouth of flaring.
Between described rotary feeder and described feeding warehouse, the ejector, be connected by flange respectively between described ejector and described blower fan, the filling pipeline.
The utility model utilizes first filter that moisture Tailings Slurry dehydration is generated dried tailings, dried tailings utilizes the gravity decline of self to impact rotary feeder after feeding warehouse stores, make the rotary feeder uniform rotation to the ejector feed, simultaneously blower fan air-supply provide filling power blow dried tailings in the ejector through filling pipeline to the filling area, can continually carry out filling operation.The whole system configuration is simple, except conventional equipment filter and blower fan, no longer needs other external equipment, has low cost, high efficiency advantage.Overcome prior art and utilized the water conservancy filling to need a large amount of electric power to drain defective waiting period of the needs after mine water that Tailings Slurry brings and the filling, also overcome the prior art dry stowing simultaneously and utilized mine car or other machinery to carry from ground to do the defective that casting resin comes the bashing inefficiency.
