Background
In the field of mine filling, part of metal mines are far away from a filling station, and the transportation cost of transporting tailings to the filling station by utilizing pipelines is high, so that the mines usually adopt filter-pressed tailings or directly adopt silt as filling materials, and the filter-pressed tailings or silt is transported to the filling station for filling by a truck, so that the problem of high cost of long-distance transportation and transportation of the tailings is solved, the filling of high-concentration paste is realized, and the matching requirement of a filling body and underground mining technology is met.
The tailings or the silt after filter pressing are conveyed to the ground surface of a filling station through a truck, then are conveyed into a scattering machine by a forklift to be scattered, the scattered tailings or silt is conveyed into a discharging bin with a metering device through a belt, and after metering, the tailings or the silt is discharged into a stirring barrel and is mixed with glue powder and water to be fully stirred, so that a homogeneous filling body is ensured to be obtained.
Because the water content of the tailings (silt) after filter pressing is high and the viscosity is high, the phenomena of wall hanging, arching and the like of materials are difficult to break and discharge in a conventional breaker, the unbroken high-viscosity materials are often generated, after being conveyed to a discharging bin through a belt conveyor for metering, when a flashboard is opened by the discharging bin to discharge the high-viscosity materials, the high-viscosity materials are easy to generate incapability of entering a stirring barrel, the materials are blocked at a chute connected with the flashboard and the inlet of the stirring barrel and are in a triangular shape, and because the high-viscosity materials cannot be continuously and stably discharged, the external high-viscosity materials are difficult to disperse, and the cement is in a continuous and uniform discharging process, so that the materials and the cement are difficult to be uniformly dispersed in a short time, and a uniform filling body cannot be formed; however, the stirring time is too long, and continuous slurry preparation and pumping filling cannot be realized.
The high-viscosity aggregate cannot be normally discharged in the discharging bin, so that the filling station cannot be filled in time, and the production of mine enterprises is seriously affected. And if the bone steady state in the discharging bin cannot be guaranteed to be continuously lowered, the aggregate enters the stirring barrel more and less when appearing, the stirring efficiency can be influenced, and the quality of the formed filling body cannot be guaranteed. If the stirring time is too short, homogeneous filling slurry cannot be formed, the filling pump is possibly blocked under the condition of heterogeneous slurry, so that the filling pump cannot send the filling slurry in a pipeline to the underground, and a pipe blockage accident is likely to happen; once the filling pipeline is blocked, a series of accidents such as blocking of the stirring barrel and the like can be caused, and the filling station enters a paralysis mode. At this time, the maintenance and filling system is time-consuming and labor-consuming, and can affect the production of mines, thereby causing great economic loss to the mines.
