Abstract
A dry-discharge system for tailings is composed of a tailings pump, a swirler, a thickening pond, a slag slurry pump and a filter pressing machine and characterized in that a pipeline of the tailings pump is connected with the swirler, an overflowing port of the swirler is communicated with the thickening pond through a water tank, a flowing port at the bottom of the thickening pond is connected with the filter pressing machine through the slag slurry pump, the thickening pond is of a conical structure, an angle of a lower cone ranges from 40 to 60 degrees, a bottom flowing port is arranged at the bottom of the thickening pond, the bottom flowing port of the thickening pond is communicated with the filter pressing machine through the slag slurry pump, overflowing clean water of the thickening pond is led to a circulation water tank through the water tank, filtered clean water of the filter pressing machine is led to the circulation water tank through the water tank, and the tailings forms dry tailings with water content lower than 20% after dehydration through the filter pressing machine, the dry tailings meet requirements of dry stacking and can be recycled, potential safety hazards of safety and environment-protection caused by slurry discharging are eliminated, back water rate reaches more than 70%, and water resource is fully circulated and utilized.
Description
Technical field
The utility model belongs to the mill tailings processing technology field, is specifically related to a kind of tailing dry heat-extraction system.
Background technology
Domestic general tailings processing method is the discharging of slurry formula at present; Though the convenient and swift and small investment of this method, long-time discharging exists great danger and pollution hidden trouble, one, the mine tailing storehouse of slurry formula discharging is an artificial mud-rock flow dangerous matter sources with high potential energy; In case accident; Cause particularly serious accident easily, two, large-area farmland takies very easily surrounding enviroment are polluted, three, the low water resource waste of recycling water utilization rate is serious.
Summary of the invention
The purpose of the utility model is to be directed against the problem that existing mill tailings slurry formula discharging exists, and a kind of tailing dry heat-extraction system that the mine tailing slurry is carried out thickening, recycling water utilization rate height, recycle is provided.
The utility model is that the scheme that the technical solution problem is adopted is: a kind of tailing dry heat-extraction system, form by tailings pump, cyclone, thickening pond, slag stock pump, filter press, and it is characterized in that the pipeline of tailings pump connects cyclone; The cyclone overfall communicates with thickening pond with tank; Described thickening pond is circular vertebral body structure, and the angle of bottom centrum is the 40-60 degree, and underflow opening is established in the bottom; The thickening pond underflow opening communicates with filter press through the slag stock pump; Thickening pond overflow clear water leads to circulating water pool with tank, and filter press leaches clear water and leads to circulating water pool with tank, and the mine tailing after the filter press dehydration forms moisture dried tailings below 20%; The utility model method for using; Moisture 82%～87% mine tailing slurry is delivered to cyclone through tailings pump, and through cyclone centrifugal sedimentation, underflow forms moisture dried tailings below 20%; Build heap through the discharge of cyclone underflow opening; Overflow flows to thickening pond through the cyclone overfall and precipitates, and from flowing to the circulating water pool recycle, deliver to filter press through the slag stock pump and dewater by the thickening pond underflow through tank for thickening pond overflow clear water; Filter press leaches clear water and flows to circulating water pool, and the tailings mud after the filter press dehydration forms moisture dried tailings discharge below 20% and builds heap.
The utility model beneficial effect, this system is reasonable in design, and technology is compact; Mine tailing moisture content after the processing is below 20%; Reach and do the heap requirement, can recycle, solved safety and environmental protection hidden danger that the discharging of slurry formula causes; The backwater rate reaches more than 70%, and water resource obtains abundant recycle.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
Accompanying drawing is the utility model sketch map.
Among the figure: 1 tailings pump, 2 cyclones, 3 cyclone overflows, 4 cyclone underflows, 5 dried tailings are built heap, 6 thickening pond, 7 thickening pond underflows, 8 thickening pond overflow clear water, 9 slag stock pumps, 10 filter presses, 11 circulating water pools, 12 leach clear water, and 13 dried tailings are built heap.
The specific embodiment
As shown in the figure, a kind of tailing dry heat-extraction system, moisture 82%～87% mine tailing slurry is delivered to cyclone 2 through tailings pump 1; Through cyclone 2 centrifugal sedimentations; Underflow 4 forms moisture dried tailings below 20%, discharges through cyclone 2 underflow openings and builds heap 5, and cyclone overflow 3 flows to thickening pond 6 through the cyclone overfall and precipitates; Thickening pond overflow clear water 8 flow to circulating water pool 11 recycles certainly through tank; Thickening pond underflow 7 is delivered to filter press 10 through slag stock pump 9 and is dewatered, and filter press leaches clear water 12 and flows to circulating water pool 11, and the mine tailing after filter press 10 dehydrations forms moisture dried tailings discharge below 20% and builds heap 13.
Claims (2)
1. tailing dry heat-extraction system; Form by tailings pump, cyclone, thickening pond, slag stock pump, filter press; The pipeline that it is characterized in that tailings pump connects cyclone, and the cyclone overfall communicates with thickening pond with tank, and the thickening pond underflow opening communicates with filter press through the slag stock pump; The thickening pond overflow is led to circulating water pool with tank, and filter press leaches clear water and leads to circulating water pool with tank.
2. a kind of tailing dry heat-extraction system according to claim 1 is characterized in that described thickening pond is circular vertebral body structure, and the angle of bottom centrum is the 40-60 degree, and underflow opening is established in the bottom.
