Beneficial effect of the present invention:
The present invention adopts the material feeding pond of linear arrangement successively, thickening pond, Buffer Pool, settling tank, clear water reserviors, carry out concentration to mine tailing, are discharged on the spot by the clear water deviate from simultaneously or recycle, concentrator structure is simple, saving space, and can realize the object of economize on electricity water-saving.
First ore pulp is carried out concentrated formation high-concentration ore slurry by the present invention, the ore pulp containing thin mud obtained is helped through the gravitational settling of progressively classification and swash plate simultaneously and fall, fine sand and thin mud is discharged respectively by sand excluding valve and mud clearing valve, finally obtain the liquid in clear water state, by regulating reset valve to control liquid level in thickening pond, clear water water quality reaching standard can be made.High-concentration ore slurry is discharged by mortar pump, and clear water can directly discharge or recycle.Like this, the structure of concentrator is simple on the one hand, and cost is low.On the other hand, the concentration of ore pulp can be realized again, obtain the clear water of recoverable or directly discharge while forming high-concentration ore slurry, raise the efficiency, save energy consumption.
The present invention adopts channeltype structure, linearly arranges, and can buriedly install, and does not substantially account for ore dressing plant volume.In addition, channel length is long, and actual settling area increases, and can make more simply to realize good effect of settling in concentrator structure simultaneously, effectively reduces the production cost of concentrator on the one hand, improves thickening efficiency on the other hand.
Described herringbone helps and falls structure increase current tortuosity and reduce settling height, thus Accelerated subsidence.
Described fine tuning structure regulates the ratio of top and the bottom passage flow ore pulp amount in described thickening pond, and then makes the clear water in clear water reserviors reach discharge standard or recycling.
The multiple swash plate of described multiple row helps the thin mud falling structure and can contribute in sedimentation low concentration ore pulp.

Detailed description of the invention
For ease of understanding, below in conjunction with the drawings and specific embodiments, the invention will be further described.
Embodiment 1
Fig. 1 of the present inventionly a kind ofly has the cut-away view helping the canal formula concentrator falling structure, annexation between each component and operation principle as follows: a kind of have the canal formula concentrator helping and fall structure, comprises the material feeding pond 2 of linear arrangement successively, thickening pond 4, Buffer Pool 9, settling tank 12 and clear water reserviors 14; Described thickening pond 4 degree of depth is greater than other four pond degree of depth, is provided with outlet 8 bottom described thickening pond 4;
Described concentrator is the enclosed construction with the top cover covering each pond, described material feeding pond 2 is positioned at the head of described concentrator, and the material inlet 1 being positioned at top cover leads to described material feeding pond 2, and ore pulp enters material feeding pond 2 through material inlet 1, cross dividing plate 3, the heavy particle sedimentation in thickening pond 4 in ore pulp.Thickening pond 4 is separated into two parts in left and right by man-like shelf 5, utilizes the increase current tortuosity of man-like shelf 5 and reduces settling height, thus Accelerated subsidence.
The permeable window 6 of device on man-like shelf 5, to regulate the ratio of top and the bottom passage flow ore pulp amount.Control method adopts push-pull valve 7, push-pull valve 7 one end is fixed on top cover, the top that the other end is fixed on man-like shelf 5 has the vertical portion of permeable window, by observing the ore pulp height in permeable window 6, regulate the height of push-pull valve 7, thus make man-like shelf 5 promote or decline, vernier control sinking speed.The heavy particle settled down is discharged by outlet 8 with the ore pulp form of high concentration.The thin mud of non-sedimentation enters Buffer Pool 9, utilizes the further sedimentation of gravity wherein.The fine sand settled down drains into thickening pond by sand excluding valve 10.The ore pulp of low concentration overflowed from Buffer Pool enters settling tank 12, in settling tank 12 along water (flow) direction every 1 meter of distribution sedimentation swash plate 13, be beneficial to thin mud sedimentation.Low concentration flow of slurry enters clear water reserviors 14 in clear water state substantially to during canal tail, and is discharged by osculum 15.The husky mud settled down in settling tank drains into thickening pond by mud clearing valve 11.For just inspection operation, equipment inspection hand-hole 16 is answered in the appropriate location of dense canal, in addition in order to ensure that ore pulp is smooth, also should arrange natural ventilation hole 17.
First design width and the length of thickening pond during use according to ore pulp amount and concentration, finely tuned by push-pull valve again after building up, to make clear water reserviors water quality reaching standard.The clear water of discharging from osculum 15 can in line or recycling.Outlet 8 connects mortar pump entrance, continuous non-stop run.Gap is run according to the size of its difference region settling amount for sand excluding valve 10 and mud clearing valve 11.Robot control system(RCS) can be equipped come.
Embodiment 2
The calculating of dense canal
Note: mineral slurry flux is designated as G (m
3/ h) sinking speed of shale is designated as V in ore pulp
1(m/s); Ore pulp level run speed is designated as V
2(m/s); Settling height is designated as H (m); Sedimentation time is designated as t (s); Dense canal height of water level is designated as h (m), and degree of depth width of the channel degree is designated as b (m); Dense canal length is designated as L (m); The quantity of sedimentation swash plate is often organized in canal body.Then there is following relational expression:
V
1=0.3 × 10
-3m/s (experimental data)
V
2＝G/(3600bh)
t＝H/V
1＝(h/n)/V
1
L＝tV
2
Calculated examples
To select last person ore deposit, ironworks: suppose often to select last person ore deposit, ironworks to measure as G=120m
3/ h, concentration is 15%.Suppose width of the channel degree b=1m, canal height of water level h=1m, quantity n=10 that often organizes sedimentation swash plate, then can calculate:
V
2＝G/(3600bh)＝120/(3600×1×1)＝0.033333m/s
t＝H/V
1＝(h/n)/V
1＝(1/10)/(0.33×10
-4)＝3030s
L＝tV
2＝3030×0.033333＝101m
If select HRC type high pressure thickener, then the area needed is at least 12m
2, be highly about 10m, bulky.As adopted canal formula concentrator, although length increases a lot, reach 101m, because be linear arrangement, can't account for plant area's too large space, and canal formula concentrator structure is simple, basic mechanical action component, operation maintenance is extremely convenient.
