Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, Fig. 1 is the overall structure front view of the first detailed description of the invention provided by the present invention.
In the first detailed description of the invention provided by the present invention, the underflow circulatory system of concentrator mainly comprises thickening pond 1, underflow cylinder 2, underflow circulating pump 3 and underflow discharge pump 4.
As shown in Figures 2 and 3, the left view of Fig. 2 underflow circulatory system that is the concentrator shown in Fig. 1; The top view of the underflow circulatory system that Fig. 3 is the concentrator shown in Fig. 1;
Wherein, thickening pond 1 is the key operation place of concentrator, and ore pulp carries out Separation of Solid and Liquid based on gravitational settling effect in thickening pond 1, thus pulp density is increased.The limpider clarified solution that thickening pond 1 top is separated is discharged by the annular chute at top, and the ore pulp that the density stayed is larger is then deposited in bottom thickening pond 1 owing to conducting oneself with dignity.Because underflow cylinder 2 is arranged on the bottom of thickening pond 1, therefore ore pulp just enters in underflow cylinder 2, engineering is commonly referred to as underflow ore pulp.Then by the effect of rake being arranged on slow circumvolve in thickening pond 1, ore pulp dewatered further thus reaches higher underflow density, meanwhile, the underflow ore pulp of thickening being discharged by bottom concentrator, ore pulp qualified for concentration is supplied to subsequent handling.
Underflow discharge pump 4, is generally arranged on thickening pond 1 bottom periphery, is mainly used in discharging being stored in the qualified underflow ore pulp of concentration in thickening pond 1.The entrance II401 of underflow discharge pump 4 is connected with the underflow cylinder 2 bottom thickening pond 1, and its outlet II402 is then connected with special plasma discharge pipeline 5.Therefore, during 4 normal operation of underflow discharge pump, under the pressure of Pulp pump, the ore pulp that concentration in underflow cylinder 3 is qualified just enters into underflow discharge pump 4, after in underflow discharge pump 4, stream turns around, flow in plasma discharge pipeline 5 from the outlet II402 of underflow discharge pump 4 again, finally discharge from plasma discharge pipeline 5 again, be supplied to subsequent handling.
Underflow circulating pump 3 is core components of the present invention, is generally also arranged on thickening pond 1 bottom periphery, and the underflow ore pulp being mainly used in making concentration qualified carries out forced circulation.The entrance I301 of underflow circulating pump 3 is connected with the underflow cylinder 2 bottom thickening pond 1, and its outlet I302 is then connected with thickening pond 1.Therefore, underflow circulating pump 3, when normal operation, by the pressure effect of Pulp pump self, makes to be deposited on the ore pulp that in underflow cylinder 3, concentration is qualified and enters from its entrance I301, after in underflow circulating pump 3, stream turns around, then flow out from the outlet I302 of underflow circulating pump 3.Because the outlet I302 of underflow circulating pump 3 is communicated with thickening pond 1, after therefore underflow ore pulp sprays from the outlet I302 of underflow circulating pump 3, flow back into again in thickening pond 1.Finally, ore pulp is forced to carry out shuttling movement and so forth, reduce yield stress and the viscosity of underflow ore pulp, after effectively preventing concentrator storing, occur pressure rake or stuck phenomenon, thus make the concentrator of the band underflow circulatory system have preparation simultaneously and store the function of ore pulp.Therefore, the concentrator of the underflow circulatory system is with when subsequent handling stops, without the need to stopping the preparation of ore pulp temporarily, the continuous seepage of ore pulp can be conducive to.
In order to strengthen the effect of underflow ore pulp forced circulation motion, the present embodiment is provided with standpipe 6 at the outer wall of thickening pond 1.The entrance of standpipe 6 is connected with the outlet I302 of underflow circulating pump 3, and its outlet is connected with thickening pond 1.Like this, underflow circulating pump 3 is first connected with standpipe 6, then is connected with thickening pond 1 by standpipe 6.Therefore, underflow circulating pump 3 is when normal operation, and the qualified underflow ore pulp of concentration, after underflow circulating pump 3, is introduced in standpipe 6, then is flow back in thickening pond 1 by standpipe 6.Because standpipe 6 is the pipelines with certain altitude, therefore after underflow ore pulp sprays from underflow circulating pump 3, the stroke that climbs carrying out certain distance can be forced to, thickening pond 1 is directly flow back into compared to after underflow circulating pump 3, this kind of mode makes the cyclic motion process of underflow ore pulp distance longer, the shuttling movement time is longer, and overall circulating effect is better.Herein preferably, standpipe 6 is parallel to the axial direction of thickening pond 1 at the setting position of thickening pond 1 outer wall, namely vertically arrange, make when the length of standpipe 6 is certain like this, underflow ore pulp need overcome self gravitation completely and vertically to climb motion, and such motion mode displacement is maximum, consuming time the longest, compared to other motion mode, improve the effect of forced circulation motion to a certain extent.Certainly, if standpipe 6 also can not vertically be arranged, the set-up mode such as with the axial direction of thickening pond 1 with certain angle also can adopt.In addition, not necessarily, therefore the quantity of standpipe 6 also not necessarily, but general, and standpipe 6 is oppositely arranged in the axial direction for the quantity of underflow circulating pump 3, can improve the effect of underflow circulation so to a certain extent.
In order to strengthen underflow ore pulp forced circulation movement effects further, the present embodiment is also provided with endless tube 7 on the axial direction of thickening pond 1.This endless tube 7 in the form of a ring, distributes round thickening pond 1, and endless tube 7 is provided with outlet, by this outlet, endless tube 7 is communicated with thickening pond 1.But endless tube 7 does not exist entrance, and underflow ore pulp directly can not enter in endless tube and circulate.For this, the present embodiment has set up a three-way pipe: the first three-way pipe 8, and one of them interface of this three-way pipe communicates with standpipe 6, and two other interface then accesses in endless tube 7, communicates with endless tube 7; Or one of them interface communicates with endless tube 7, two other interface then accesses in standpipe 6, and the connected mode communicated with standpipe 6 is also passable.No matter but which kind of connected mode, by the effect of the first three-way pipe 8, finally all make standpipe 6 be communicated with endless tube 7.So, underflow ore pulp is after spraying from the outlet I302 of underflow circulating pump 3, and a part enters in standpipe 6 carries out motion of climbing, and then flows back in thickening pond 1; Another part by the first three-way pipe 8, flow into and is divided into two strands after in endless tube 7 and carries out horizontal endless motion simultaneously, finally flow back in thickening pond 1 after the exit of endless tube 7 is converged after entering standpipe 6.
In addition, foregoing has mentioned standpipe 6 and endless tube 7, the outlet of this two pipe is all connected with thickening pond 1, therefore standpipe 6 is all be arranged on the outer wall of thickening pond 1 with the outlet of endless tube 7, only because standpipe 6 has certain altitude, therefore the outlet of standpipe 6 and the exit position of endless tube 7 are one high and one low distribution in the axial direction.And important be in circumferential direction, although the exit position of the exit position of standpipe 6 and endless tube 7 is not fixed, need the certain angle that staggers in the circumferential.The ore pulp that the ore pulp exported due to endless tube 7 and standpipe 6 export, not in the same side, is more conducive to the ore pulp flowing in thickening pond 1 like this.If but at homonymy, when thickening pond 1 diameter is very large, the ore pulp at the outlet I302 place of underflow circulating pump 3 also can only flow in side, the ore pulp of opposite side is by likely compacting, to likely be stuck or occur pressure rake phenomenon when harrow frame turns to compacted region, and so then not have the underflow circulatory system and solve effect that is stuck or pressure rake.
Herein preferably, the exit position of standpipe 6 and the exit position of endless tube 7 become 30 ° of-180 ° of angles in the axial direction, and optimum angle is 180 °, and namely the outlet of standpipe 6 and the outlet of endless tube 7 lay respectively at the two ends of thickening pond 1 certain diameter, are oppositely arranged.Like this, the move distance of underflow ore pulp in endless tube 7 just equals the girth of whole endless tube 7, reaches the longest move distance and the longest run duration, improves the effect of forced circulation motion to a certain extent.Certainly, the exit position of standpipe 6 also can not become 180 ° of angles in the axial direction with the exit position of endless tube 7, and the angles such as all the other such as 30 °, 60 °, 90 ° also can reach object of the present invention.
In sum, the present embodiment, by setting up endless tube 7, recycles the first three-way pipe 8, and standpipe 6 is communicated with endless tube 7.When 3 normal operation of underflow circulating pump, underflow ore pulp can carry out the motion in vertical plane and horizontal plane simultaneously, single straight line motion in one dimension is equivalent to upgrade to spatial three-dimensional movement, drastically increase move distance and the run duration of underflow ore pulp, therefore significantly improve the effect of underflow ore pulp forced circulation motion.
In addition, the effect of underflow ore pulp forced circulation motion can also be strengthened again further.For this reason, the present embodiment has set up the second three-way pipe 9.One of them joint of this three-way pipe communicates with plasma discharge pipeline 5, and two other joint then communicates with endless tube 7; Or one of them joint of this three-way pipe communicates with endless tube 7, and two other joint then communicates with plasma discharge pipeline 5.No matter which kind of connected mode, by the effect of the second three-way pipe 9, all makes plasma discharge pipeline 5 communicate with endless tube 7.Therefore, after underflow ore pulp sprays from the outlet II402 of underflow discharge pump 4, a part directly enters in plasma discharge pipeline 5 and discharges, and be supplied to subsequent handling, another part flow in endless tube 7 by the second three-way pipe 9 when through plasma discharge pipeline 5, and the outlet flow again through endless tube 7 carry out cyclic motion in endless tube 7 after is got back in thickening pond 1.To sum up, due to the existence of the second three-way pipe 9, plasma discharge pipeline 5 and endless tube 7 are communicated.Underflow ore pulp, while discharging from plasma discharge pipeline 5, can also flow in endless tube 7 and proceed circulation, improves the effect of underflow ore pulp forced circulation motion to a certain extent.
The present embodiment also provides a kind of concentrator, and comprise fuselage and be arranged at the underflow circulatory system on fuselage, wherein, the underflow circulatory system is identical with foregoing, repeats no more herein.
