Abstract
The utility model provides a high-efficiency disk-type permanent-magnet and weak-magnet separator. A mine unloading scraper of the utility model is composed of stainless steel and rubber, the stainless steel is attached to the rubber. And thus soft touch is realized between the scraper and the stainless steel disk faces. A mine unloading water tube is additionally arranged above disks for washing the disk faces, and plays roles of lubricating and cleaning. The stainless steel or aluminum retainer ring is replaced by common iron retainer ring to increase stiffness and ensure the parallelism among the disk faces. Reinforcing rib connecting is used among the stainless steel disk faces to increase the stiffness and the flatness of the disks. The permanent-magnet and weak-magnet separator is already used for treating dust removal water in a sintering plant, magnet separation water-falling ground, etc., and obtains appreciable economical benefits. The utility model is particularly suitable to be used for sintering, smelting and steel rolling sewage treatments of low concentration and large volume dose.
Description
The utility model belongs to the strongly magnetic material sorting equipment, particularly the weak magnetic wet magnetic separation equipment of collar plate shape permanent magnetism.
The weak magnetic separator of wet type has two kinds of belt magnetic separator and drum magnetic separators.Be used for processing of trade effluents such as the strongly magnetic material sorting of iron and steel industry mine ore dressing, environmental protection etc. and ferrous metal sintering, smelting, steel rolling etc.At present, belt magnetic separator is replaced by drum magnetic separator gradually.In drum magnetic separator, magnet only works in a side, so the sorting area is little, thereby the processing of the ore pulp that inapplicable flow is big, concentration is little, for example contain the sewage disposal of ferromagnetic substance.
In order to make full use of magnetisable material, in a tame steel tube factory of Sweden, be provided with a disc type magnetic separator (seeing " metal wire industry " third phase PP175～177 in 1981), the disk specification is 1.25m, and each disc thickness is 10mm, includes 5000 small permanent magnets with certain style configuration; The disk side is covered with corrosion resistant plate; Distance between disk is approximately 20mm; The shell of disk immerses in the groove, and disk slowly rotates with 1～2 rev/min speed against current, makes the mud that is accumulated on the disk be taken out of the water surface, with a continuous glue system conveyer belt system mud is scraped off from magnetic disk surface.
Shoudu Iron and Steel Co " scientific and technological information " has been reported a disk magnetic separator in April, 1974, and its card is made with aluminium sheet, adopts strontium ferrite as permanent magnet, forms with adhering with epoxy resin.
All there are some problems in these disk magnetic separators, and Sweden's formula disk magnetic separator adopts glue system driving-belt to unload mud, complex structure, and also disposal ability is very low, though the card diameter has reached 1.25m, per hour can only handle 15m
3Sewage.The induction cleaning shoe of Shoudu Iron and Steel Co formula magnetic separator and aluminium matter card wear no resistance, and card rigidity is not enough; The card flatness and the depth of parallelism are not enough, the card serious wear, thereby in industry, do not use always.
The purpose of this utility model provides the weak magnetic wet type of a kind of disc type permanent magnetism and selects machine, and it is simple that it scrapes the mud system architecture, scrapes mud efficient height, and the wearability of card is good, and flatness, the depth of parallelism and good rigidity sort the efficient height.
According to the utility model, unload the ore deposit scraper plate and adopt the rubber that on corrosion resistant plate, sticks automatic sealing function to combine, the available copper screw is fixed on the corrosion resistant plate both sides with rubber, also can corrosion resistant plate and rubber be bonded together with water-fast high-strength adhesive.Can make scraper plate and card realize soft the contact like this, reduce wear.When scraper plate when card sweeps magnetic material, under the effect of magnetic force, make rubber be close to card, realize from movable sealing.
According to the utility model, above disk, set up and unload the mineral water pipe, in order to wash away disc surfaces, between scraper plate and card, play lubrication on the one hand, reduce friction, make magnetic sludge unload totallyer on the other hand, improve sorting result.
According to the utility model, card is made with the thick corrosion resistant plate of 2mm, links with reinforcement between the stainless steel card, welds together with extraordinary welding method, guarantees that card is smooth, the intensity height.Reinforcement is made of non-magnet material.For example make of corrosion resistant plate.
According to the utility model, adopt plain cast iron to replace aluminium or stainless steel back-up ring as the back-up ring between the adjacent discs, guaranteeing under the prerequisite of equipment performance, thereby the rigidity of increase back-up ring is guaranteed the depth of parallelism between each card, reduces manufacturing cost.
According to the utility model, several are fixed on the same main shaft by permanent magnet and the made disk of panel, between the adjacent discs cylinder iron back-up ring be separated by, disk main shaft two ends are fixed on the wall of Bilge with rolling bearing, disk is with contrary sewage (or ore pulp) the flow direction rotation of about 2 rev/mins rotating speed, sewage to be selected flows through between each disk, the ferromagnetism solid particle is by the choosing dish time, under the condition of F magnetic＞F machinery, be attached on the magnetic disk surface by magnetic force F magnetic, and rotate to disk and to unload the mining area, unloaded mineral water and unloaded the ore deposit scraper plate in this and be discharged in the concentrate chute, finish ore dressing process.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side-looking phantom.
As shown in Figure 1, the disk magnetic that is made up of Sr-ferrite magnetic material or other permanent-magnet material is 2, its outer bread forms card 1 take stainless sheet steel (thickness as about 2mm), a plurality of this kind disks are installed on the main shaft 3 with certain interval, separate with back-up ring 10 between the disk, this main shaft is installed in the ball bearing 7 on the Bilge 4, drive system drives main shaft and the rotation of each disk through shaft coupling 8, strongly magnetic material in the sewage is adsorbed on the disk, produce and unloaded ore deposit scraper plate 9 behind the water surface and scrape in mud (concentrate) chute 5, go round and begin again to rotate and finish ore dressing process.
As shown in the figure, characteristics of the present utility model are to unload ore deposit scraper plate 9 needs to adopt corrosion resistant plate and the rubber slab combination that the automatic-sealed effect is arranged to make the flute profile scraper plate, the both sides of this flute profile scraper plate 9 are with the fixing rubber of brass screws, make and realize soft contact between stainless steel card 1 and the flute profile scraper plate 9, reduce the card wearing and tearing. When scraper plate was scraped the magnetic concentrate from card, under the effect of magnetic force, rubber was adjacent to card more again, thereby realized automatic-sealed.
As shown in Figure 1, another feature of the present utility model is that establishing one at disk unloads mineral water pipe 8. In order to wash away disc surfaces, play lubricated and flushing action, improve beneficiating efficiency.
As shown in Figure 1, another characteristics of the present utility model be between the disk 1 cylinder iron back-up ring 10 separate, thereby increase the rigidity of system and the depth of parallelism between each card.
As shown in Figure 2, another characteristics of the present utility model are that the reinforcement 4 made from non-magnet material (for example stainless steel) between card connects, and increasing rigidity and the glacing flatness of disk, thereby have improved the efficient of system.
