Abstract
The utility model discloses a fine and coarse coal slime recovery device, relates to the field of fine coal washing equipment and provides a fine and coarse coal slime recovery device with a good dehydration effect. The fine and coarse coal slime recovery device comprises a separation device and a dehydration device which are sequentially arranged, wherein the dehydration device is a vibrating arc-shaped sieve and a vertical centrifugal machine which are sequentially arranged; the separation device is preferably a concentrated cyclone; and furthermore, the drainage outlet on the vertical centrifugal machine is connected with a material inlet on the concentrated cyclone. The fine and coarse coal slime recovery device can be applied to the washing process in a coal preparation plant.
Description
Technical field
The utility model relates to cleaned coal washing appliance field, relates in particular to a kind of smart coarse slime retracting device.
Background technology
Smart coarse slime reclaims sorting and two steps of dehydration.
The screening installation of coarse slime, present alternative have coal slime heavy medium cyclone, spiral, RC, the sorting of TBS waterpower etc.But the separating density of spiral, RC, the sorting of TBS waterpower is higher, should not go out to hang down the sorting means of ash products as coking coal.Adopt the sorting of coal slime heavy medium cyclone, special-purpose special thin medium must be arranged when arranging separately, can increase the medium recovery difficult, increase the consumption that is situated between.Also must set up the standalone media system on stream, to dispose the dense medium suspension liquid of certain density, heavily Jie technology that cyclone matches but if employing major diameter main separation cyclone and minor diameter coal slime heavily are situated between, the required thin medium of small diameter cyclone sorting derives from the overflow of major diameter cyclone, because two suspension systems influence each other, thus bigger to realizing full factory medium system balance and controlling difficulty automatically.In addition, the Bed for Fine Coal after the sorting and suspension together advance magnetic separator, cause magnetic separation material concentration height, granularity big, also can reduce the medium productive rate of magnetic separator, and the consumption that is situated between is higher relatively.
Dehydration equipment adopts sieve bend and high frequency sieve now, the sieve bend preliminary hydro-extraction, and the further dehydration of high frequency sieve, shortcoming is that dehydrating effect is general, management maintenance is complicated.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of dehydrating effect good smart coarse slime retracting device.
For the technical scheme that addresses the above problem employing is: smart coarse slime retracting device comprises sorting unit and the dewater unit that sets gradually along the material moving direction, vibration sieve bend and the vertical centrifugal machine of dewater unit for setting gradually along the material moving direction.
Further be: sorting unit is for concentrating cyclone.
Further be: concentrated cyclone is provided with material inlet, and vertical centrifugal machine is provided with discharge outlet, and discharge outlet is connected with material inlet.
The beneficial effects of the utility model are: use circularoscillations sieve and vertical centrifugal machine that coarse slime is dewatered, the dehydration area is big, manageability is safeguarded.Coarse slime has been carried out efficient sorting, guaranteed that cleans ash reaches requirement, has improved clean coal yield.Use to concentrate cyclone sorting coarse slime, strong to the adaptability of ature of coal, long service life does not have other moving components, manageability, and production cost is low, arrangement convenience.
Description of drawings:
Fig. 1 is smart coarse slime retracting device structural representation;
Be labeled as among the figure: sorting unit 1, dewater unit 2, vibration sieve bend 3, vertical centrifugal machine 4, discharge outlet 5, material inlet 6.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
In order to provide a kind of dehydrating effect good smart coarse slime retracting device, smart coarse slime retracting device comprises sorting unit 1 and the dewater unit 2 that sets gradually along the material moving direction, vibration sieve bend 3 and the vertical centrifugal machine 4 of dewater unit 2 for setting gradually along the material moving direction.Use circularoscillations sieve 3 and 4 pairs of coarse slimes of vertical centrifugal machine to dewater, the dehydration area is big, manageability is safeguarded, coarse slime has been carried out efficient sorting, guarantees that cleans ash reaches requirement, has improved clean coal yield.Especially owing to there is the effect of centrifugal force field, so the effect of desliming dehydration is significantly improved vertical centrifugal machine 4 as final dewatering equipment.
Sorting unit 2 has plurality of devices to select, and the utility model preferred equipment is for concentrating cyclone.Use to concentrate cyclone sorting coarse slime, strong to the adaptability of ature of coal, long service life does not have other moving components, manageability, and production cost is low, arrangement convenience.
In the prior art, the moisture of being deviate from by vertical centrifugal machine 4 will enter down step flotation operation, contain thick cleaned coal in the moisture that the fault that may occur for fear of vertical centrifugal machine causes it to deviate from, thereby influence bottom flotation operation, concentrated cyclone is provided with material inlet 6, vertical centrifugal machine is provided with discharge outlet 5, and discharge outlet 5 is connected with material inlet 6.The moisture that discharge outlet 5 is deviate from vertical centrifugal machine 4 enters concentrated cyclone, does not directly enter the flotation operation, the influence to the flotation operation that the fault that can avoid vertical centrifugal machine to occur causes.
