In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of tailings dewatering device is characterized in that: mainly comprise cyclone, thickener, vacuum band-type filter machine and sedimentation basin; The siccative that the mine tailing slurry of discharging from enrichment plant forms through cyclone, thickener, vacuum band-type filter machine successively.
Further, the water of collecting in the said sedimentation basin is in the water of deviating from through said cyclone, said thickener, said vacuum band-type filter machine effect one or more; The water that contains a small amount of mine tailing in the said sedimentation basin gets into said thickener and does the second dehydration processing.
Further, between said thickener and said vacuum band-type filter machine, also be provided with the flocculant add-on system, make fine particle and the flocculant in the solution in the mine tailing slurry form floc sedimentation and rapid subsidence.
Further, described flocculant is polyacrylic or polyacrylamide.
Further, said sedimentation basin also is connected with a collecting pit, and said collecting pit is used for the clear water that the overflow of collecting precipitation pond goes out.
Further, the clear water in the said collecting pit gets into the enrichment plant recycle.
A kind ofly utilize said tailings dewatering device to carry out dehydration method, it is characterized in that comprising following steps:
At first, the mine tailing slurry entering cyclone that flows out from enrichment plant carries out preliminary hydro-extraction, and the concentration of dehydration back mine tailing slurry improves, and the water of cyclone generation gets into sedimentation basin;
Secondly; Mine tailing slurry after cyclone is handled gets into concentration basin and carries out the sedimentation concentration; Further improve the concentration of mine tailing slurry, the mine tailing slurry through sedimentation gets into the vacuum band-type filter machine dewatering operation then, and the water of deviating from from concentration basin and vacuum band-type filter machine all gets into sedimentation basin;
Once more, the mine tailing slurry of being crossed by the vacuum band-type filter machine processed becomes siccative; The clear water that overflow goes out in the sedimentation basin gets into collecting pit and sends back to enrichment plant and continues to recycle;
At last; The water that contains a small amount of mine tailing in the sedimentation basin is delivered to the thickener second dehydration and handles; And the mine tailing efferent duct place of the flocculant for preparing after by the processing of concentration basin dropped into, make fine particle and formation floc sedimentation of the flocculant in the solution and rapid subsidence in the mine tailing slurry; The mine tailing slurry is handled the back through vacuum band-type filter machine again and is formed siccative then, and the moisture content of said siccative is lower than 15%.The interpolation quality of said flocculant is 0.5 ‰-5 ‰ of a mine tailing slurry gross mass.
This tailings dewatering device has following beneficial effect:
(1) the utility model tailings dewatering method and dewater unit are well eliminated the risk of utilizing the tailing dam dehydration, effectively avoid the generation of accident.
(2) the utility model tailings dewatering method and dewater unit drop into that expense is few, operating cost is low, dehydration rate is high, reasonable in design, the science of this device simultaneously, and whole device is safe and reliable to operation.
Description of drawings
Fig. 1: the utility model tailings dewatering process flow diagram.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is further specified:
Fig. 1 shows a kind of tailings dewatering device, mainly comprises cyclone, thickener, vacuum band-type filter machine and sedimentation basin; The siccative that the mine tailing slurry of discharging from enrichment plant forms through cyclone, thickener, vacuum band-type filter machine successively.The water of the water of collecting in the sedimentation basin for deviating from through cyclone, thickener, vacuum band-type filter machine effect; The water that deposition contains a small amount of mine tailing in the sedimentation basin gets into said thickener and makes second dehydration and handle.Between thickener and said vacuum band-type filter machine, also be provided with the flocculant add-on system, make fine particle and the flocculant in the solution in the mine tailing slurry form floc sedimentation and rapid subsidence, flocculant is polyacrylic or polyacrylamide.Sedimentation basin also is connected with a collecting pit, and said collecting pit is used for the clear water that the overflow of collecting precipitation pond goes out, and the clear water in the collecting pit gets into the enrichment plant recycle.
As shown in Figure 1; The mine tailing slurry of discharging from enrichment plant through cyclone, thickener, vacuum band-type filter machine be successively because; Initial mine tailing slurry concentration is very low, and moisture is very high, therefore at first rotates through the high speed of cyclone; Can slough most water fast, the ore pulp after cyclone is handled is the ore pulp of high concentration.
This ore pulp that contains more bulky grain mineral high concentration enters into thickener then, and the ore pulp of this kind state is more suitable for sedimentation and concentrates, and then obtains the higher ore pulp of concentration; The ore pulp of from thickener, discharging is higher because of its concentration; Moisture is difficult for deposition and separates with the solid layering; Therefore need to increase to use vacuum band-type filter machine, this machine is a medium with filter cloth or filter screen, makes the slip horizontal arrangement on filter medium; Make full use of slip gravity and pull of vacuum and realize Separation of Solid and Liquid, the moisture content that obtains at last is lower than 15% siccative.
A kind of this tailings dewatering device that utilizes carries out dehydration method, comprises following steps:
At first, the mine tailing slurry entering cyclone that flows out from enrichment plant carries out preliminary hydro-extraction, and the concentration of dehydration back mine tailing slurry improves, and the water of cyclone generation gets into sedimentation basin;
Secondly; Mine tailing slurry after cyclone is handled gets into concentration basin and carries out the sedimentation concentration; Further improve the concentration of mine tailing slurry, the mine tailing slurry through sedimentation gets into the vacuum band-type filter machine dewatering operation then, and the water of deviating from from concentration basin and vacuum band-type filter machine all gets into sedimentation basin;
Once more, the mine tailing slurry of being crossed by the vacuum band-type filter machine processed becomes siccative; The clear water that overflow goes out in the sedimentation basin gets into collecting pit and sends back to enrichment plant and continues to recycle;
At last; The water that contains a small amount of mine tailing in the sedimentation basin is delivered to the thickener second dehydration and handles; And the mine tailing efferent duct place of the flocculant for preparing after by the processing of concentration basin dropped into, make fine particle and formation floc sedimentation of the flocculant in the solution and rapid subsidence in the mine tailing slurry; The mine tailing slurry is handled the back through vacuum band-type filter machine again and is formed siccative then.The interpolation quality of flocculant is 0.5 ‰-5 ‰ of a mine tailing slurry gross mass.
The utility model tailings dewatering method and dewater unit are well eliminated the risk of utilizing the tailing dam dehydration, effectively avoid the generation of accident.This device input expense is few simultaneously, operating cost is low, and dehydration rate is high.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
