Abstract
The present invention relates to the central feeding cylinder of a kind of novel concentrator, including cylinder, feed pipe, baffle-wall and fixing otic placode, feed pipe feeds central feeding cylinder the downward inclination angle in 2-3 �� along the tangential direction of cylinder, it is welded with the baffle-wall vertical with cylinder inner wall tangential direction at central feeding cylinder inwall, make the ore pulp of entrance by baffle-wall vertical on central feeding barrel, it is effectively facilitated air venting and dissipation excess energy, improves mixing efficiency; The ore pulp making entrance center barrel produces turbulent flow after running into spoiler, promotion ore pulp is sufficiently mixed with flocculant, forms bigger floc sedimentation, improves dehydrating effect, improves the work efficiency of concentrator.
Description
Technical field
The present invention relates to solid-liquid separation technique field, particularly to the central feeding cylinder of a kind of concentrator.
Background technology
Concentrator is based on the solid-liquid separating equipment of gravitational settling effect, is generally and is built up the cylindrical shape shallow slot with the cone end by concrete, timber or metal welding fishplate bar as structural material, is divided into common concentrator and Hhigh-efficient thickener. Concentrator give after ore deposit mixes with flocculant, enter into concentrator by central feeding cylinder, thus carrying out a series of sedimentation and centrifugation. At present, the mode that direct feed is usually taken enters the central feeding cylinder of concentrator, but it is undesirable to there is sedimentation effect, the problem of concentrated effect difference. Yet suffering from more bubble owing to this mode enters in the ore pulp of concentrator, solid particle is attached on bubble, affects flocculation, makes flocculant and ore pulp undercompounding, and then have impact on effect of settling. When ore deposit stream flings decanting zone, being formed and return up stream, make the granule just settled down be rushed again, cause particulate to settle, Hhigh-efficient thickener then causes the destruction to established flocculation group. And owing to the concentrated effect of concentrator is poor, overflow water is muddy, has a strong impact on the recycling of water, and running ore thickness is low, and underflow density is low to 15-20%.
Summary of the invention
The technical problem to be solved is that existing concentrator charging undercompounding, sedimentation effect are undesirable, a kind of concentrator feeding cylinder is provided, can ensure that the deep pan feeding of concentrator, the ore pulp making entrance passes through baffle-wall vertical on central feeding barrel, is effectively facilitated air venting and dissipation excess energy; The ore pulp making entrance center barrel produces turbulent flow after running into spoiler, promotion ore pulp is sufficiently mixed with flocculant, forms bigger floc sedimentation, improves dehydrating effect, improves the disposal ability of concentrator.
The technical scheme is that a kind of concentrator central feeding cylinder, including cylinder, it is characterised in that also include feed pipe, baffle-wall and fixing otic placode;Described baffle-wall is fixedly installed on cylinder inner wall, and extension in cylinder radially; Described fixing otic placode is fixing with cylinder outer wall to be connected, and is positioned at the middle and upper part of cylinder outer wall, for cylinder and concentrator crossbeam being fixed; Described feed pipe runs through the sidewall of cylinder, and connects with the inside of cylinder.
Downward-sloping 2-3 �� of described feed pipe, fixes with cylinder side wall by welding, and the internal diameter of described feed pipe is the 30% of barrel bore.
Described baffle-wall has 8 pieces, being evenly distributed on cylinder inner wall by welding, one of described baffle-wall is positioned at described feed pipe mouth of pipe place, is highly the 80% of cylinder heights, the length of described baffle-wall is the 13% of barrel bore, it is possible to make the ore pulp of entrance central feeding cylinder by described baffle-wall.
Described fixing otic placode, has 4 pieces, is evenly distributed on cylinder outer wall by welding.
The height of described baffle-wall is baffle-wall along the axial distance of cylinder, and length is that width is the thickness of baffle-wall along cylinder radially to the distance extended in cylinder.
The invention has the beneficial effects as follows:
1) that reduces flocculant makes consumption, and after improvement, flocculant is reduced to 100g/t by 300g/t, has saved production cost;
2) the mixed phenomenon of race it is prevented effectively from, it is to avoid the loss of noble metal;
3) significantly improve the underflow density of concentrator, original 10-15% bring up to about 25%, and then improve the treating capacity of concentrator;
4) being obviously improved clean result, the pH value of the oxidizing slag after three sections of countercurrent washings is brought up to about 3 by original 1.5-2, reduces the addition of the white lime of link of sizing mixing, reduce further cost;
5) production capacity of the 30 meters of concentrators applying central feeding cylinder of the present invention reaches 600m3/ h, underflow mass fraction of solids is stable about 30%, and overflow water float quality Fractional domination is 0.01%; Overflow water is limpid, improves overflow water quality, not only ensure that the water quality of recirculated water, and meets the demand of mill water; Underflow density increases, it is provided that the treating capacity of concentrator, reduces the consumption of flocculant, reduces the operating cost of concentrator; Improve the transportation concentration (being brought up to 30% by 18%) of mine tailing simultaneously, reduce the conveying cost of mine tailing, Tailings transportation cost 9.72 ten thousand yuan can be saved every year. Additionally high-concentration tailings is discharged into Tailings Dam, decreases the warehouse-in amount of tailing water, is conducive to building a dam and the formation, particularly flood season on dry beach advantageously ensure that safety level, it is simple to the management of Tailings Dam.
