Abstract

The utility model relates to a permanent magnetic separator, a magnetic mechanism of which consists of a set of magnetic rings which are in parallel and fixed at intervals on axial support plates (11) symmetrically spread; the same working face of the magnetic rings has the same polarity, and two corresponding working faces have opposite polarity. A transmission mechanism consists of a main shaft (2) and a radial support disc (3) driven by the main shaft and with one rim fixed and connected together with the center of the radial support plates. An unloading mechanism consists of a collecting groove (4) arranged at the upper part of magnetic inner holes on both sides of the radial support disc, with the outer end fixed on a machine frame (5) and the inner end impending, and a scraper (7) corresponding to the collecting groove. Because magnetic fields in the magnetic separating area are evenly spread in a line, the recovery rate of the magnetic iron can be improved to 85percent.

Description

Permanent magnetic separator

One, technical field

The utility model relates to the metallic magnetic optional equipment, particularly a kind of permanent magnetic separator that is made of permanent-magnetic clamp and drain separator.

Two, background technology

Reclaim Armco magnetic iron in order to contain the ferromagnetic material from discarded mine tailing or other, the inventor once disclosed a kind of permanent magnetic separator in Chinese patent ZL99225206.7.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; Transmission mechanism 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; Shedding mechanism by the magnet ring endoporus top, the outer end that are positioned at radial support disk both sides be fixed on the frame, inner unsettled material collecting tank and scraper plate that should material collecting tank constituted.The magnet ring of this magnetic separator is that to control direction with the polylith permanent magnets by adjacent magnetic patch magnetic pole opposite and connect composition, because the magnetic line of force is the magnetic pole from the magnetic pole of a magnetic patch to adjacent magnetic patch, the magnetic line of force that is positioned at magnetic separation district center position is less near the density of line of magnetic force at magnet ring working face place, magnetic field intensity relatively a little less than, this just causes the Armco magnetic iron yield in the ore pulp at this position of flowing through to reduce relatively.Therefore, the Armco magnetic iron rate of recovery of this magnetic separator is not high enough, the highlyest can only reach 65%.

Three, summary of the invention

The purpose of this utility model is improved the above-mentioned background technology, provides a kind of rate of recovery higher permanent magnetic separator.

The permanent magnetic separator that the utility model provides, its magnetic mechanism, transmission mechanism and shedding mechanism and above-mentioned background technology are basic identical, the same working face polarity of the different one group of magnet ring that just constitutes magnetic mechanism identical; Corresponding two working face polarity are opposite.

For the polarity that makes magnet ring distributes by above-mentioned requirements, the magnet ring available cross-section becomes the whole magnetic patch of rectangle and connects formation (basic identical with the above-mentioned background technology); Also can adopt the polylith permanent magnets to constitute by the two sides that magnetic force is adsorbed on tabular annulus.Manufacture and the latter is easier.

Compare with the above-mentioned background technology, the advantage of the utility model permanent magnetic separator is: because two working face magnetic in each magnetic separation district are opposite, the magnetic line of force from a working face to another working face, being even straight line distributes, magnetic field intensity everywhere is identical, so its Armco magnetic iron rate of recovery can reach 85%, increase rate reaches 20%, remarkable in economical benefits.

Fig. 3 is the sectional view (amplification) of adjacent two magnet rings;

Fig. 4 is the stereogram of Fig. 1 middle scraper.

Five, the specific embodiment

In conjunction with Fig. 1 to Fig. 4, the utility model magnetic separator is made up of 16 magnet rings, each magnet ring is that to be adsorbed on thickness by magnetic force be that the two sided of 8 millimeters tabular annulus 9 constitutes to 10 millimeters tabular permanent magnet 8 by 48 thickness, permanent magnet 8 on the same working face is controlled by the magnetic pole equidirectional, and makes corresponding two the working face magnetic poles of adjacent magnet ring opposite.For making the magnetic patch fixation, can add the resistance to water Chemical Felter between magnetic patch and the annulus and between the magnetic patch seam.16 magnet rings become the parallel interval state, and eight axial support plates 11 with bolt and symmetrical distribution fuse respectively.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 12 by bearing and bearing block 13.The material collecting tank 4 that becomes heeling condition is from inside to outside installed on the top of the endoporus that is formed by magnet ring in above-mentioned radial support disk both sides respectively, and this material collecting tank outer end is fixed on the frame 5, and inner close support disk becomes vacant state.17 scraper plate 7 openings between two relative above magnet ring working faces become tiltedly direction down; corresponding material collecting tank; its lower end slightly runs off magnetic area; scraper plate is that the hollow stainless steel backing 15 interpolation rubber slabs 14 of V-arrangement constitute by the cross section; the working face of magnet ring is close at its edge; for ease of change the scraper plate that is worn under non-stop-machine state, scraper plate top has support 16, and support top has handle 17 and hangers 18.During use, hangers inserted be located on the frame cross bar 6, in the groove that opening makes progress.When need were changed scraper plate, hand-held handle upwards rotated, and scraper plate also rotates thereupon, withdraws from between two magnet rings, and hangers is taken from groove, changes another scraper plate.For beyond the discharging between the magnet ring of avoiding being in the centre flows to material collecting tank along the card of support disk 3, run off the material collecting tank position in the two sides of support disk and weld respectively to centroclinal and have an annular striker plate 10 of upright wing.

Technical parameters such as each size of above-mentioned magnetic separator, magnet ring quantity, magnetic field intensity can require to design according to the different service conditions in scene.
