Abstract

The utility model relates to a circular permanent magnetic separator. A magnetic mechanism is composed of a set of mutual parallel magnetic rings which are fixed on axial supporting boards at intervals, the cross section of the magnetic rings are rectangular, and the axial supporting boards are symmetrically distributed. A driving mechanism is composed of a main shaft and a radical supporting disc which is driven by the main shaft, and the periphery of the radical supporting disc is connected with the centers of the axial supporting boards. An ore discharging mechanism is composed of a set of scraping boards which are respectively arranged on the side surfaces of the upper parts of the magnetic rings and two ore collecting slots, and the two ore collecting slots are respectively arranged on the upper part of an inner hole of a magnetic ring and at both sides of the radical support disc. The outer end of each ore collecting slot is fixed on a machine frame, and the inner end is suspended. The utility model uses scraping boards to replace water which is used for flushing and discharging ore, and the utility model is suitable for water deficient regions.

Description

A kind of annular permanent magnet magnetic separator

The utility model relates to the metallic magnetic optional equipment, particularly a kind of annular permanent magnet magnetic separator.

At present, China Iron Works Plant is limited by ore-dressing technique and appointed condition, also has the considerable part Armco magnetic iron in the mine tailing of discharging, and for reclaiming these Armco magnetic irons, the inventor once disclosed a kind of permanent magnetic separator in Chinese patent ZL95230718.9.The magnetic mechanism of this magnetic separator is become rectangle, is parallel to each other and the magnet ring of fixed interval on the axial support plate that is symmetrically distributed constitutes by one group of cross section.The transmission mechanism of magnetic separator is made of the radial support disk that a periphery and the above-mentioned axial support plate center fixation of main shaft and drive thereof connects together.The ore unloader structure of magnetic separator is positioned at water spray water pipe between the magnet ring upper side and two respectively by one group and lays respectively at that magnet ring endoporus top, radial support disk both sides, outer end are fixed on the frame, inner unsettled mining collecting trough constitutes.

Facts have proved that the area that this magnetic separator is relatively abundanter in water resource, water price is relatively cheap is used, effect is better, and in the water-deficient area, higher because of water price, just seem economical inadequately.

The purpose of this utility model is improved on the basis of above-mentioned existing permanent magnetic separator, provides a kind of not water to unload the annular permanent magnet magnetic separator in ore deposit.

The annular permanent magnet magnetic separator that the utility model provides, its magnetic mechanism, transmission mechanism and mining collecting trough and existing magnetic separator are identical, just will unload the mineral water pipe make into one group be positioned at respectively between the two sides, said magnet ring top, and the scraper plate of corresponding mining collecting trough.

With this magnetic separator ore dressing, the Armco magnetic iron that adsorbs on the magnet ring side walks to top with the magnet ring rotation and is swept by scraper plate, falls into mining collecting trough by gravity, replaces water to dash with scraper plate, is specially adapted to the water-deficient area.

Accompanying drawing is depicted as structural representation of the present utility model.Wherein Fig. 1 is its side view, and Fig. 2 is along Figure 1A-A cutaway view.

See figures.1.and.2, this annular permanent magnet magnetic separator is made up of 16 magnet rings, abrasion resistance for the magnetic field intensity that improves the magnet ring surface (to improve the magnetic separation yield) and magnet ring surface, the naked magnetic patch 9 that it is rectangle by one group of (this machine is 48) cross section that each magnet ring adopts is spliced to form, and is embedded in the framework that is made of outer hoop 8 and interior hoop 10.16 magnet rings become the parallel interval state to fuse with 8 axial support plates 12 of bolt and symmetrical distribution.The center fixation of each gripper shoe is (available bolting) on the periphery of a radial support disk 3, and this support disk is fixed on the main shaft 2 by flange bearing 1 and axle cap, and main shaft is erected on the concrete ore deposit groove 13 by bearing and bearing block 14.On endoporus top that magnet ring forms, the both sides of the radial support disk symmetry mining collecting trough 4 the cross section forming V-shape being installed and being tilted from inside to outside respectively, this mining collecting trough outer end is fixed by bolts on the frame 5, and is inner near support disk and unsettled, becomes cantilever-shaped.17 scraper plates 7 lay respectively between the two sides, magnet ring back upper place, and the cross section forming V-shape is made of the rubber slab that has steel backing, and the upper end is enclosed within on the axle 6, so that produce the replacing offset plate around axle at any time after the wearing and tearing, the lower end is facing to mining collecting trough.Be unloading beyond the ore deposit flows to mining collecting trough along the card of support disk 3 between the magnet ring of avoiding being in the centre, weld respectively to centroclinal and have an annular striker plate 11 of upright wing the position that runs off mining collecting trough in the two sides of support disk.

The Armco magnetic iron that adsorbs from mine tailing when magnetic separator is mingled with silt more for a long time, can stretch into the sparge pipe (not drawing among the figure) that runs off mine tailing liquid level position between each magnet ring, can spray tiny current to two sides for one group in installation on the frame.

Parameters such as each size of this magnetic separator, magnet ring quantity, magnetic field intensity all can require to design according to the different service conditions in scene.
