Invention belongs to a kind of preparation equipment.
Continuous centrifugal concentrating machine is the gravitational separation equipment that a kind of right-74 microns sludge can carry out continuous sorting very effectively.
The double tapered rotary drum centrifugal ore separator that uses is to grow up after single tapering rotary drum centrifugal ore separator of Yunnan Province of China tin industry company invention at present.The critical component of double tapered rotary drum centrifugal ore separator is rotary drum (claiming the ore dressing tube again), and it is by a semi-cone angle α
1=10 °, length L
1The hollow round platform of=0.21D (calling the first awl chamber in the following text) and a semi-cone angle α
2=2.5 °, length L
2The hollow round platform of=0.32D (calling the second awl chamber in the following text) is formed (internal diameter that D is two awl junctions, chamber in the literary composition).Ore pulp is given to the rotary drum first awl chamber interior walls of rotating around dead axle from fixing to the ore deposit mouth, the second awl chamber of flowing through again, and the particle that density is little flows outside the expelling tube with liquid, is mine tailing; The particle that density is bigger is but separated out from ore pulp, is deposited on the second awl chamber interior walls, sorts the time through one section to the ore deposit, valuable mineral becomes a particular geometric shapes in the drum inner wall enrichment, just stop to go out centralized collection with the valuable mineral that the pressure clear water will deposit on drum inner wall to the ore deposit.So sorting operation is finished in circulation.
Rotary drum adopts the double tapered rotary drum centrifugal ore separator of said structure form, its tailing stream and concentrate flow are alternately discharged in 360 ° of scopes of the second awl chamber outlet side, therefore it can only carry out sorting operation periodically, so claim this ore separators to be the periodicity centrifugal ore separator again.Though it also can sort-74 microns sludge effectively, sorting periodically of it not only reduced its disposal ability, but also need to be equipped with ore feeder, towards instruction, executing agency and the power of ore deposit device, mine distributor and their actions.The existence of these auxiliary bodies has increased the unit cost, and complicated equipment is given and produced and management has brought inconvenience, especially at their exercise not harmonies or when malfunctioning, will seriously influence sorting index, even loses fully and sort usefulness.
The improvement invention that The present invention be directed to the problem of double tapered rotary drum centrifugal ore separator existence and do.
Fig. 1 is the continuous centrifugal concentrating machine complete machine schematic diagram after improving, frame (1), running part (2), chassis (3), rotary drum (4), outer cover (5), give ore deposit mouth (6), washer (7), towards ore deposit mouth (8a), (8b), (8c).Fig. 2 is the structural representation of continuous centrifugal concentrating machine rotary drum (4), the first awl chamber (9), the second awl chamber (10).Fig. 3 is the schematic diagram between the various product discharge areas of continuous centrifugal concentrating machine mine-discharging terminal, natural ore discharge district θ
1, force ore discharge district θ
2, the two is combined into mine tailing discharge area θ, chats discharge area m, concentrate discharge area β.Fig. 4. figure is the structural representation of continuous centrifugal concentrating machine outer cover (5), tube cover (11), reflecting plate (12), big mining collecting trough (13), little mining collecting trough (14).
Continuous centrifugal concentrating machine characteristics after the improvement are semi-cone angle α of the awl chamber of first in the rotary drum (4) (9)
1=10 °-20 °, the length L of the second awl chamber (10)
2=0.05D-0.09D, and obtained the best semi-cone angle α of the first awl chamber
1=14 °-16 °, the optimum length L of the second awl chamber
2=0.059D; Adopt the rotary drum (4) of new construction parameter, increased the axial flow velocity of ore pulp in tube, strengthened choosing branch process, and made nature ore discharge district θ
1Shared angle is less than 360 °.In remaining angular range, with the clear water of washer (7) ejection random deposition is arrived the top layer of drift earlier in the second awl chamber less particle elutriation of density, use again towards the clear water of ore deposit mouth (8a) ejection they are gone out outside the tube, Here it is artificial pressure ore discharge district θ
2, the mine tailing that natural ore discharge district and pressure ore discharge district discharge is outside big mining collecting trough (13) the discharge machine of outer cover (5).The shared angle of mine tailing discharge area θ is still less than 360 °.Again in remaining angular range, all go out the drift on the second awl chamber outside the tube with pressure clear water towards ore deposit mouth (8b), (8c) ejection, be the chats of chats discharge area m and the concentrate of concentrate discharge area β, they outside the different passage discharge machines of little mining collecting trough (14), categorised collection.Reached the purpose of continuous ore dressing.
From the above, be understood that: force ore discharge district θ
2, chats discharge area m and concentrate discharge area β, be requirement according to production target, will be under ore deposit mouth (8a), (8b), (8c) effect go out the different product interval that thing is divided into artificially; With the drift of second awl on the chamber all can be gone out tube outer and again not with natural ore discharge district θ
1Mine tailing be mixed into principle mutually, select concentrate discharge area β and natural ore discharge district θ
1Separation, counter thus pushing through can suitably be arranged towards the installation site of ore deposit mouth (8a), (8b), (8c) and washer (7).That is to say, be positioned at θ towards ore deposit mouth (8a) and washer (7)
1With θ
2Between.If necessary, can also be at θ
2And install towards ore deposit mouth (8b) between the m again or (8b) and (8c), to reach drift with the second awl chamber all towards most purpose.
In order to adapt to the continuous ore-dressing practice of this machine, and be convenient to change consumable accessory, outer cover (5) is designed to combining structure shown in Figure 4, tube cover (11), reflecting plate (12), big mining collecting trough (13) and little mining collecting trough (14).It is material that each parts of the chassis of the continuous centrifugal concentrating machine after the improvement (3), rotary drum (4) and outer cover (5) all adopt the wear-resisting engineering plastics of light weight, has reduced the rotary inertia of rotary drum (4) in the continuous centrifugal concentrating machine, cuts down the consumption of energy.
