Description

Adopt the ring type permanent magnetic separator of anhydrous discharging

The utility model relates to the metallic magnetic optional equipment, particularly a kind of ring type permanent magnetic separator that adopts the discharging of magnetic absorption method.

In order to reclaim Armco magnetic iron from discarded mine tailing, the inventor once disclosed a kind of ring type permanent magnetic separator in Chinese patent ZL95230718.9.This magnetic separator adopts the high-pressure water pipe discharging, and water consumption is bigger, uses in the water-deficient area to be subjected to certain limitation; In addition, the water discharging, the material concentration of recovery is low, and need handle through second dehydration sometimes can be as the finished product utilization.

The purpose of this utility model is to remedy above-mentioned the deficiencies in the prior art, designs the ring type permanent magnetic separator of a kind of not water discharging.

The ring type permanent magnetic separator that the utility model provides, its magnetic mechanism and above-mentioned prior art do not have big difference, promptly become rectangle, be parallel to each other and the magnet ring of fixed interval on the axial support bar that is symmetrically distributed constitutes by one group of cross section, just must to limit be same polarity to the surperficial magnetic pole of each magnet ring, and the polarity on corresponding two surfaces of adjacent magnet ring is opposite.Its transmission mechanism and prior art are also basic identical, are made of the periphery of main shaft and main shaft drive and the radial support disk that the axial support bar is fixed together.Unlike the prior art be, its shedding mechanism is to make with non-magnet material by one group, the hopper that its half covering of the fan is inserted in the rotatable discharging disk in the above-mentioned magnet ring gap respectively and is positioned at this discharging disk rear constitutes.Each discharging disk is a hollow form, there is one group of permanent magnet that is installed on the fixed axis at corresponding position of inserting magnet ring in its cavity, the magnetic field intensity of permanent magnet is greater than the magnetic field intensity of magnet ring, and corresponding with it the respectively magnet ring surface polarity of the polarity of two sides of corresponding magnet ring is opposite; Have one group on the outer surface of discharging disk and become radial material-blocking wing from the center.

The discharge process of the utility model permanent magnetic separator is: the Armco magnetic iron that adsorb from the mine tailing of bottom on the magnet ring surface of rotation forwards in the discharging disk gap with magnet ring, owing to be arranged in the magnetic field intensity of the fixing permanent magnet magnetic field intensity of discharging disk cavity greater than the magnet ring surface, make Armco magnetic iron by magnet ring surface then be adsorbed on the surface of discharging disk, rotation along with the discharging disk, Armco magnetic iron shifts out field regions, this moment is attached by the retaining wing holder of discharging disc surfaces, be rotated further, after entering hopper, be dumped into hopper by centrifugal force and gravity, finish discharge process.

By the decision design parameter, the discharging rate of this machine is reached more than 95%.

This magnetic separator owing to adopt the magnetic absorption method to replace original water discharging method, has not only been saved water, has widened the range of application of magnetic separator, and has made the Armco magnetic iron of recovery not need second dehydration, greatly reduces production cost.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.

Fig. 1 is the side view (partly cuing open along magnet ring and discharging disc centre line) of the utility model permanent magnetic separator; Fig. 2 is along Figure 1A-A cutaway view.

In conjunction with Fig. 1 and Fig. 2, the utility model magnetic separator is made up of eight magnet rings 2, each magnet ring becomes the permanent magnet 9 of rectangle to press the splicing of outer surface same polarity by the polylith cross section, is fixed on the both sides of gripper shoe 8, and eight magnet rings fuse its parallel interval with 8 symmetries axial support bar 3 step by step; The center of axial support bar and two ends are separately fixed on the periphery of three radial support disks 7, and this radial support disk is fixedlyed connected with main shaft 5 by sending out blue 6, and main shaft is erected on the concrete ore deposit groove 1 by bearing and bearing block 4; At the rear of magnet ring is nine discharging disks of being made by non-magnet materials such as stainless steel or rigid plastics 10, the radius of each discharging disk is equivalent to the radial width of magnet ring, inside is hollow, has 16 retaining wings 13 that become radial projection from the center on its two sides; Nine discharging disks fuse, and half covering of the fan of its each disk inserts (slightly gapped with the magnet ring surface) in the magnet ring gap respectively, can rotate around fixed axis 14 by bearing 15; In the cavity of discharging disk, there is a fan-shaped support plate 11 that is installed on the fixed axis 14 at corresponding position of inserting magnet ring, inlays one group of magnetic field intensity on this gripper shoe greater than the permanent magnetic strip 12 more than the magnet ring magnetic field intensity twice.Hopper 16 is set up at the rear of corresponding discharging disk.The magnet ring of this machine and discharging disk can be driven respectively by two reductors by a motor, make it adopt different rotating speeds to rotate by the direction of arrow among the figure.
