Abstract
The utility model discloses a tailings dehydrating and dry discharging system. The system comprises a first section swirler which is connected with a first section slurry pump, wherein an overflowing port of the first section swirler is sequentially connected with a second section slurry pump and a second section swirler; and the bottom flow ports of both the first section swirler and the second section swirler are communicated with a feed port of a dehydrating screen. By utilizing the system, the use amounts of medicines of calcium hypochlorite and the like can be reduced, the mineral separation cost is lowered, and the tailings dehydrating and dry discharging system satisfies environmental protection requirements formulated by China.
Description
Technical field
The utility model relates to the dried heat-extraction system of tailings dewatering.
Background technology
In the mine tailing treating processes, make the CN-content of cyanide wastewater reach the calcium hypochlorite that national requirements must add q.s, will cause like this beneficiation cost to increase substantially.CN-in calcium hypochlorite and ore pulp reaction must have the sufficient time just can react completely, and due to along with treatment scale increases, thereby will select the agitation vat of certain specification and quantity, must the redesign factory building, increase cost, and reduce working efficiency.
The utility model content
The purpose of this utility model is to provide a kind of dosing such as calcium hypochlorite that reduces, and reduces the beneficiation cost expense, reaches the dried heat-extraction system of tailings dewatering of the environmental requirement of national regulation.
For achieving the above object, the utility model adopts following technical scheme: the dried heat-extraction system of a kind of tailings dewatering, comprise the one section swirler that is connected with one section slag stock pump, and the overflow port of one section swirler connects two sections slag stock pumps and two sections swirlers successively; The underflow opening of the underflow opening of one section swirler and two sections swirlers all leads to the opening for feed of draining screen.
Below the discharge port of described draining screen, correspondence is provided with surge tank.
The corresponding setting of opening for feed of the discharge port of described surge tank and a chemical reaction groove, chemical reaction groove notch top also correspondence arrange a dosing tank, and the discharge port of chemical reaction groove leads to Tailings Dam.
The overflow port of described two sections swirlers connects thickner, the overflow port access production plant of thickner, and the underflow opening of thickner is by arranging one section slag stock pump of pipeline access of hose pump.
the dried heat-extraction system of tailings dewatering described in the utility model, sludge containing cyanogens by one section slag stock pump and one section swirler after, the ore pulp that overflows from one section swirler enters two sections slag stock pumps and two sections swirlers, from one section, the ore pulp of two sections swirler underflow opening discharges all enters draining screen and carries out processed, the ore pulp that two sections swirlers overflow enters thickner and concentrates, the ore pulp that thickner overflows returns to the Production Flow Chart recycling, thickener underflow mouth ore pulp is out squeezed into hose pump through one section a cluster cyclone classification again, the dried slag that draining screen is discharged enters chemical reaction groove again and adds calcium hypochlorite to carry out reaction treatment by dosing tank after the surge tank clear water is sized mixing.Like this, cyanogen-containing tailing is actual according to producing, CN-concentration is higher, but after being deviate from, most of cyanide wastewater can return to the production plant utilization, ore pulp another part dewaters through draining screen, and the remainder cyanide wastewater is still stayed in dried slag, with clear water, dried slag is sized mixing after dilution, CN-concentration reduces greatly, more just can reach requirement after adding a certain amount of calcium hypochlorite after chemical reaction.
By using the dried heat-extraction system of tailings dewatering, can make most of cyanide wastewater Returning process recycling, the recovery part medicament, the usage quantity that reduces dosing and reduce calcium hypochlorite reduces the beneficiation cost expense, thereby reaches the environmental requirement of national regulation.

Embodiment
By the dried heat-extraction system of a kind of tailings dewatering shown in Figure 1, comprise that the overflow port of 2, the one sections swirlers 2 of one section swirler that are connected with one section slag stock pump 1 connects two sections slag stock pumps 11 and two sections swirlers 12 successively; The underflow opening of the underflow opening of one section swirler 2 and two sections swirlers 12 all leads to the opening for feed 3 of draining screen 4, the underflow opening of the underflow opening of one section swirler 2 and two sections swirlers 12 all be positioned at draining screen 4 opening for feeds 3 directly over, below the discharge port of draining screen 4, correspondence is provided with surge tank 5, the opening for feed of surge tank 5 one ends is over against the discharge port below setting of draining screen 4, the discharge port of surge tank 5 the other ends and the corresponding setting of the opening for feed of a chemical reaction groove 7, the discharge port of surge tank 5 the other ends be positioned at chemical reaction groove 7 opening for feeds directly over.The equal upward opening of notch of surge tank 5 and chemical reaction groove 7, go back correspondence above chemical reaction groove 7 notches one dosing tank 6 is set, the discharge port of dosing tank 6 is over against the notch of chemical reaction groove 7, and the discharge port of chemical reaction groove 7 leads to Tailings Dam (Tailings Dam is not shown).Certainly, the utility model is not limited to above-mentioned form, and the underflow opening of the underflow opening of one section swirler 2 and two sections swirlers 12 also can all access the opening for feed 3 of draining screen 4 by pipeline.
The overflow port of described two sections swirlers 12 connects thickner 13 by pipeline, and the overflow port 9 of thickner 13 accesses production plant by pipeline, and the underflow opening 8 of thickner 13 is by arranging one section slag stock pump 1 of pipeline access of hose pump 10.
the dried heat-extraction system of tailings dewatering described in the utility model, sludge containing cyanogens by one section slag stock pump 1 and one section swirler 2 after, the ore pulp that overflows from one section swirler 2 enters two sections slag stock pumps 11 and two sections swirlers 12, from one section, two sections swirlers 2, the ore pulp that 12 underflow openings are discharged all enters draining screen 4 and carries out processed, the ore pulp that two sections swirlers 12 overflow enters thickner 13 and concentrates, the ore pulp that thickner 13 overflows returns to the Production Flow Chart recycling, thickner 13 underflow openings 8 ore pulp is out squeezed into hose pump 10 through one section swirler 2 classification again, the dried slag that draining screen 4 is discharged enters chemical reaction groove 7 again and adds calcium hypochlorite to carry out reaction treatment by dosing tank 6 after surge tank 5 adds clear water to size mixing.Like this, cyanogen-containing tailing is actual according to producing, CN-concentration is higher, but after being deviate from, most of cyanide wastewater can return to the production plant utilization, ore pulp another part dewaters through draining screen 4, and the remainder cyanide wastewater is still stayed in dried slag, with clear water, dried slag is sized mixing after dilution, CN-concentration reduces greatly, more just can reach requirement after adding a certain amount of calcium hypochlorite after chemical reaction.
