Abstract
The present invention relates to a technique for separating and recovering suspension liquid from a dense medium, which belongs to the separation technique. The technique comprises a separation screen. A method is carried out according to the following steps that each screen hole of an operation screen for recovering the suspension liquid is from 1mm to 4mm; products for dense medium separation are put in the operation screen with screen holes of 1mm to 4mm to recover the suspension liquid; a magnetic separator is directly used for recovering the separated and removed dilute suspension liquid, magnetic objects are recovered in a medium barrel to be used again, and non-magnetic objects separated by the magnetic separator enter a coarse coal slurry recovering system. The technique adopts a vibration screen or a fixing screen with the screen holes of 1mm to 4mm for operation, the operation screen has large screen holes and small areas, the required factory building is small, the building construction investment is less, and the production cost is low. The magnetic separator is used for directly recovering the separated and removed dilute suspension liquid, the magnetic objects are recovered back to the medium barrel to be used again, the non-magnetic objects separated by the magnetic separator enter the coarse coal slurry recovering system, and the present invention has the advantages of good separation effect and obvious economic benefit.
Description
Technical field
The present invention relates to a kind of technology of classifying and retrieving suspension liquid from dense medium, belong to the sorting process technical field.
Background technology
Current dense medium separation reclaims suspension from sorted product operation is to be that gravity flow screen or the vibratory sieve of 0.35～1.0mm carries out at sieve aperture.Sieve not adding down suspension that water spray deviates from directly to be got back to qualified Jies bucket and utilizes, and sieve adding the dilute suspension of spraying water down and entering magnetic separator and the magnetic thing is got back to the medium bucket utilize.
The method of above-mentioned recovery suspension, can cause unnecessary capital expenditure like this and strengthen production cost because sieve aperture will need very greatly at the area of its sieve of 0.35～1.0mm along with the increase of dense medium separation product volume.This technology is that uneconomical its design is also unreasonable.
Summary of the invention
The object of the present invention is to provide a kind of operation of reclaiming suspension is to carry out on the gravity flow screen of 1～4mm or the vibratory sieve at sieve aperture, sieve does not add the suspension of spraying water down and directly gets back to the utilization again of qualified Jie's bucket, sieve added the dilute suspension of deviating from of spraying water down and entered magnetic separator, the magnetic thing is got back to the medium bucket utilize.The area of required sieve is little, and capital expenditure is little, the technology of the classifying and retrieving suspension liquid from dense medium that production cost is low.
The technical scheme that realizes the foregoing invention purpose is: a kind of technology of medium classifying and retrieving suspension liquid, comprise separating sieve, and this method is undertaken by following step,
The sieve aperture of the operation sieve of a, recovery suspension is 1～4mm;
B, the product of dense medium separation is fed sieve aperture is that the operation sieve of 1～4mm carries out the recovery of suspension;
C, directly reclaim the dilute suspension that sorting is deviate from magnetic separator, the magnetic thing is got back to the medium bucket utilize, the nonmagnetics that magnetic separator is selected enters coarse slime recovery system.
Adopt technique scheme, it is vibratory sieve or the gravity flow screen operation of 1～4mm that the present invention selects sieve aperture for use, and the operation compass screen surface is long-pending little, and required factory building is little, and capital expenditure is few, production cost.Directly reclaim the dilute suspension that sorting is deviate from magnetic separator, the magnetic thing is got back to the medium bucket utilize, the nonmagnetics that magnetic separator is selected enters coarse slime recovery system.Because its screen-aperture is big, thus good separation effect, remarkable in economical benefits.
Description of drawings
Accompanying drawing 1 is a process chart of the present invention.
The present invention will be further described below in conjunction with the drawings and the specific embodiments.
The specific embodiment
Gravity flow screen or vibratory sieve that Job Filter sieve diameter of the present invention is 1～4mm.Its process is undertaken by following step operation referring to accompanying drawing 1:
1. the product of dense medium separation is fed gravity flow screen or the vibratory sieve that sieve aperture is 1～4mm and carry out the recovery of suspension.
2. the end at gravity flow screen or vibratory sieve adds an amount of water spray spray as required.
3. will sieve down and not add suspension that water spray deviates from and directly get back to qualified Jies bucket and utilize again, sieve was added the dilute suspension of spraying water down enter magnetic separator and the magnetic thing is got back to the medium bucket utilize again.
4. the product that will sieve feeds dehydration equipment and dewaters, and obtains qualified products at last.
5. the nonmagnetics that magnetic separator is selected feeds coarse slime recovery system.
Specific embodiment is referring to accompanying drawing 1:
1, the sieve aperture of vibratory sieve is selected 2mm for use, adds water spray at the latter end of vibratory sieve.
2, the product of dense medium separation is carried out the recovery of suspension with vibratory sieve.
3, will sieve down the suspension that not adding sprays water deviates from and directly get back to the utilization again of qualified Jie's bucket.
4, will sieve down and add dilute suspension that water spray deviates from and enter magnetic separator and the magnetic thing is got back to the medium bucket utilize again.
5, the product that will sieve feeds dehydration equipment and dewaters, and obtains qualified products at last.
6, the nonmagnetics that magnetic separator is selected feeds coarse slime recovery system.
Claims (2)
1, a kind of technology of classifying and retrieving suspension liquid from dense medium comprises separating sieve, it is characterized in that, this method is undertaken by following step,
The sieve aperture of the operation sieve of a, recovery suspension is 1～4mm;
