Abstract
The invention discloses an ore dressing tailing transmission device and method of alumyte, which comprise the following parts: sedimentation groove (8), condensed underflow transmission pipe (3) to connect the sedimentation groove (8), dielectric inlet (6) of screw rod pump (9) to connect the other end of condensed underflow transmission pipe (3) and dielectric outlet (7) of screw rod pump (9) to connect the transmission pipe (5). The invention guarantees the tailing density about 45 percent, which transmits the condensed tailing paste when the viscosity reaches 580mPa.S.
Description
Affiliated technical field
The present invention relates to a kind of feedway and carrying method of milltailings, relate in particular to a kind of transport device for dense phase and carrying method of carrying high concentration, full-bodied bauxite gangue that be applicable to.
Background technology
It is a kind of common technology that milltailings is carried, and what the conveying that milltailings is starched was adopted at present is that centrifugal pump is carried.Transport conveyor constructions is seen Fig. 1, and it is that milltailings 1 is passed through thickener 2, is transported to centrifugal pump 4 by concentrating underflow transfer line 3 then, by transfer line 5 mine tailing is delivered to the mine tailing storehouse again.But this feedway and carrying method are fit to carry the mine tailing of low viscosity (LV), low concentration.
Bauxite gangue character is different from other mine tailing coloured and ferrous metal ore, rising along with tailings concentration, the mine tailing slurry viscosity sharply raises, tailings concentration about 45% in, viscosity reaches 580mPa.S, even adding dispersing agent, viscosity also reaches about 100mPa.S, and resistance of ducting loss strengthens, and required pump total (pumping) head is very big, can't adopt said apparatus to carry, the bauxite gangue conveying technology also is the new problem that the ore dressing interface is faced.
Summary of the invention
The transport device for dense phase and the carrying method that the purpose of this invention is to provide a kind of suitable conveying bauxite.
The objective of the invention is to be achieved through the following technical solutions: the bauxite gangue transport device for dense phase, its structure is as follows: subsider, the concentrated underflow transfer line that is connected with subsider, the other end that concentrates the underflow transfer line is connected with the medium inlet of screw pump, and the media outlet of screw pump is connected with transfer line.
The bauxite gangue transport method for concentrate phase, it comprises following processing step: milltailings concentrates through subsider earlier, and the concentrated underflow after the sedimentation compression enters screw pump by the road, outwards carries through transfer line after screw pump output again.
The application of screw pump in bauxite gangue is carried.
After adopting technique scheme, can guarantee tailings concentration about 45%, when viscosity reaches 580mPa.S, the high concentrated phase mine tailing slurry of smooth delivery of power.Remedied the blank of carrying high concentrated phase bauxite gangue slurry technology.
Below in conjunction with the drawings and specific embodiments the present invention is done and to describe in further detail.
Description of drawings
Fig. 1 is the structural representation of traditional bauxite gangue transport device for dense phase;
Fig. 2 is the structural representation of bauxite gangue transport device for dense phase of the present invention.
Among the figure, 1, milltailings; 2, thickener; 3, concentrate the underflow transfer line; 4, centrifugal pump; 5, transfer line; 6, medium inlet; 7, media outlet; 8, subsider; 9, screw pump.
The specific embodiment
Below embodiments of the invention are described in detail in conjunction with the accompanying drawings, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 2, bauxite gangue transport device for dense phase structure of the present invention is as follows: the subsider 8 that is used for concentrating milltailings 1, the exit end of subsider 8 is connected with concentrated underflow transfer line 3, the other end that concentrates underflow transfer line 3 is connected with the medium inlet 6 of screw pump 9, and the media outlet 7 of screw pump 9 is connected with transfer line 5.
The bauxite gangue transport method for concentrate phase, it comprises following processing step: milltailings 1 is introduced into subsider 8, concentrate through subsider 8 then, concentrated underflow is sent into screw pump 9 by concentrating underflow transfer line 3 again, is delivered to the mine tailing storehouse through transfer line 5 again after screw pump 9 outputs.
Claims (3)
1, bauxite gangue transport device for dense phase, it is characterized in that structure is as follows: subsider (8), the concentrated underflow transfer line (3) that is connected with subsider (8), the other end that concentrates underflow transfer line (3) is connected with the medium inlet (6) of screw pump (9), and the media outlet (7) of screw pump (9) is connected with transfer line (5).
2, bauxite gangue transport method for concentrate phase, it comprises following processing step: milltailings concentrates through subsider (8) earlier, concentrated underflow after the sedimentation compression enters screw pump (9) by the road, outwards carries through transfer line (5) after screw pump (9) output again.
