Description
Technical field
This utility model relates to technical field of waste water processing, in particular, is a kind of black mine ore dressing wastewater treatment equipment.
Background technology
At present, China's ferrous metal mine beneficiation wastewater processes and uses common thickener to carry out natural sedimentation more.Effects of purification quality is poor.Water outlet does not reaches the requirement of national wastewater discharge standard, to this end, into inclined-plate clarifying basin is repacked common thickener in more domestic ore dressing plants, although this sedimentation tank effect is quite a lot of, but improvement expenses is high, and service life is short, easily blocks, and maintenance load is big.
Utility model content
This utility model is for the problems referred to above, providing a kind of black mine ore dressing wastewater treatment equipment, by installing a Cyclonic reactor between common thickener centre strut and cake frame, shape is round table-like, inside arranges multi-layer rotational flow guide plate, repacks cyclone-flocculation sedimentation tank into；Preferably improve deposition efficiency and the tailings concentration of existing thickener, anion-polyacrylamide flocculant is added sick at mixing drum, and implement thickener underflow computer controlled automatic, the disposal ability deficiency and the Tailings Slurry transportation concentration that solve thickener are relatively low, the overall accumulated amount of mine tailing ore pulp is caused to exceed the rated capacity of Mars pump, add clay content in outsourcing ore deposit to increase, the problem causing this factory's efflux wastewater severe overweight.
The technical solution adopted in the utility model is:
Black mine ore dressing wastewater treatment equipment of the present utility model, including thickener, mixing drum, cyclone-flocculation sedimentation tank and computer control system, described thickener is connected with mixing drum, described mixing drum is logical to be connected with the import of pulp storage tank, the outlet of described pulp storage tank is connected with cyclone-flocculation sedimentation tank import, the outlet of cyclone-flocculation sedimentation tank is connected to Tailings Dam, and described computer control system is connected with thickener, dosing pump and cyclone-flocculation sedimentation tank respectively.
Owing to using said structure, make black mine ore dressing wastewater treatment equipment while making full use of original processing equipment, can also preferably improve existing thickener deposition efficiency and Tailings transportation concentration, this device technique is advanced, economic, practical and reaches the waste water efficiently processed, and can widely popularize application.
Black mine ore dressing wastewater treatment equipment of the present utility model, described thickener is that two 15m thickeners are parallel with one another, wherein the overflow of two thickeners pumps into mixing drum after converging, the underflow of its two thickener is connected to flotation device, and copper mine mouth and cobalt concentrate mouth that described flotation device is arranged are respectively connecting to mixing drum.Described mixing drum is Mars pump mixing drum, and this mixing pump is provided with the dosing pump for adding medicament；It is anion-polyacrylamide flocculant that described dosing pump adds the medicament of mixing drum.
Owing to using said structure, thickener bottom blow-down rate significantly improves, achieve 1 Mars pump and carry the control target of whole mine tailing ore pulps, and by having affirmed that in the settling velocity of flocculate and two aspects of turbidity of supernatant anion-polyacrylamide flocculant is to processing ferrous metal mine beneficiation wastewater effect of settling, anion-polyacrylamide flocculant is added in Ma Ersi mixing drum, removal efficiency is high so that efflux wastewater compliance rate after treatment reaches 100%.

The black mine ore dressing method of wastewater treatment of device of the present utility model comprises the steps:
Step 1, the magnetic tailing of grinding building being sent into 2 15m thickeners, after sand setting, its underflow pumps into flotation device and carries out flotation, and the mine tailing after flotation is from flowing to Mars pump mixing drum.
While step 2, step 1, the overflow of 2 15m thickeners is converged, be then fed into mixing drum stirring.
In step 3, mixing drum, the Tailings Slurry of excess returns to thickener.
Step 4, when the mass concentration of former aqueous suspension be 21540mg/L, pH=8.05, during temperature 6 DEG C, open compound pump, add anion-polyacrylamide flocculant, mixing drum gradually enters pulp storage tank.
Step 5, the ore pulp in pulp storage tank is pumped into 18m cyclone-flocculation sedimentation tank, after reaction, Chinese effluent.
During above-mentioned black mine ore dressing waste water treatment process, also need to use computer that the technological parameter of thickener, dosing pump is detected automatically, and implement to automatically control to the production overall process of enrichment facility by underflow discharge amount closed-loop control system and anion-polyacrylamide flocculant addition closed-loop control system.
Owing to using said structure, it is achieved that the underflow amount of thickener and cyclone-flocculation sedimentation tank is automatically controlled, and then whole overall accumulated amounts of mine tailing ore pulp are controlled to suitable with Mars pump capacity, thus reach to process efficiently the effect of waste water.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1. improve treatment effeciency and the Tailings Slurry transportation concentration thereof of thickener, on the basis of former thickener structural portion is constant, one Cyclonic reactor is installed between the centre strut and cake frame of thickener, multi-layer rotational flow guide plate is set so that treatment effeciency and the transportation concentration of thickener significantly improve in round table-like inside reactor.
2. achieve enrichment facility and produce automatically controlling of overall process, this utility model have employed computer control system, by using computer that the major parameter of thickener and dosing pump is detected automatically, and by implementing to automatically control to the production overall process of enrichment facility to underflow discharge amount closed-loop control system and anion-polyacrylamide flocculant addition closed-loop control system.
The most significantly improve purification of waste water efficiency, the system and device processed by above-mentioned waste water so that efflux wastewater compliance rate 100% after treatment, handling rate 100%, rate of deposition 99.85%, other water quality index is below national wastewater discharge standard.
4. create direct economic benefit, improved sewage disposal system, national requirements standard all can be reached so that the over standard discharges of great number can be exempted from reality produces and improve expenses such as imposing pollution emission standard expense, making enterprise obtain direct economic benefit owing to waste water processes.
