A feeding device which is composed of a feeder (4) and a distributor (5) is arranged above the carrying belt (2), and a dividing panel (6) is arranged below the carrying belt (2) and on the outer side of the permanent magnetic roller (1); the permanent magnetic roller (1) is composed of a plurality of annular magnets of same diameter and pure iron rings which are ranged at interval, and the annular magnets which are arranged on the both sides of the pure iron ring have same polarity. The utility model has the advantages of small size, light weight, high magnetic induction strength, etc. The utility model can be widely used for the separation of magnetic minerals with non-magnetic minerals, and the utility model is particularly suitable for the dry separation of blocky strong magnetic materials whose granularity is 5-80 millimeters.
Description
The utility model relates to a kind of permanent magnet dry type magnetic ore separator, especially relates to the permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor of being made up of permanent magnetic roll assembly of roll magnetic separator, tail wheel, conveyer belt.Be applicable to separating of magnetic mineral and non magnetic ore, dry-type separation to the block strongly magnetic mineral material of granularity between 80～5 millimeters is particularly suitable, can be widely used in industries such as metallurgy, cement, pottery, grain processing, and environmental improvement field such as rubbish, sewage disposal.
For the dry-type separation of strongly magnetic mineral, general equipment is magnetic drum at present.Magnetic drum claims magnetic pulley again, and two kinds of permanent magnetism and electromagnetism are arranged.Publish China Machine Press in April, 1994 " more detailed description page has been done to structure, specification and the performance thereof of CT type permanent-magnet cylinder in volume PP117～126 in the Chinese preparation equipment handbook.The diameter of CT type permanent-magnet cylinder is big, do not wait for 1500 millimeters to from 500 millimeters of , equipment volume is big, energy consumption is high, particularly when it adopts common ferrite magnetic to be, because of it forms magnetic system in common mode, its surface induction intensity has only 150～170 milli teslas.In order to improve the magnetic induction intensity on magnetic drum tube surface, have to replace Ferrite Material to form magnetic system with expensive rareearth magnetic material such as neodymium iron boron, tube surface induction intensity can reach 210～220 milli teslas like this, but has improved the device fabrication cost greatly.
The purpose of this utility model is exactly at the above-mentioned problems in the prior art, provides that a kind of volume is little, in light weight, cost is low and magnetic induction intensity can reach the above permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor of 220 milli teslas.
For achieving the above object, the utility model permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor by the following technical solutions:
The utility model permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor contains permanent magnetic roll assembly of roll magnetic separator, tail wheel, conveyer belt, mandrel, and the conveyer belt top is provided with charging gear, conveyer belt below, permanent magnetic roll assembly of roll magnetic separator arranged outside demarcation strip; Described permanent magnetic roll assembly of roll magnetic separator is to be formed alternately by a plurality of diameters identical toroidal magnet and pure iron ring, and the toroidal magnet polarity of pure iron ring both sides is identical.
For reducing magnetic dispersion, between permanent magnetic roll assembly of roll magnetic separator and mandrel, be provided with magnetic shield, be provided with every disk again at the permanent magnetic roll assembly of roll magnetic separator two ends.
For further describing the utility model, the utility model permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor is described in more detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the utility model permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor complete machine structure contact figure.
Fig. 2 is the permanent magnetic roll assembly of roll magnetic separator A-A cutaway view among Fig. 1.
Fig. 3 is that the permanent magnetic roll assembly of roll magnetic separator among Fig. 1 cuts open the partial enlarged drawing that shows along the A-A face.
Fig. 4 is a tripper B-B cutaway view among Fig. 1.
In the utility model permanent magnetic roll assembly of roll magnetic separator dry-type magnetic extractor complete machine structure contact figure shown in Figure 1, permanent magnetic roll assembly of roll magnetic separator 1 drives tail wheel 3 by conveyer belt 2 and rotates together; Nearly permanent magnetic roll assembly of roll magnetic separator 1 place is provided with charging gear above conveyer belt 2, and charging gear is made up of vibra feeder 4 and tripper 5; Below conveyer belt 2, permanent magnetic roll assembly of roll magnetic separator arranged outside demarcation strip 6; Nearly permanent magnetic roll assembly of roll magnetic separator 1 place is provided with material scraper 7 below conveyer belt 2.In assorting room, vibra feeder 4 is given to material on the travelling belt 2 through tripper 5, when moving to permanent magnetic roll assembly of roll magnetic separator 1 top with travelling belt 2, magnetic material is adsorbed because of magneticaction, automatically come off in the feed bin of demarcation strip 6 inboards when turning to the bottom, the granular material that part sticks on the conveyer belt is scraped by material scraper 7; And non-magnetic material drops on the outside of demarcation strip 6 at gravity and centrifugal action lower edge horizontal parabola track.
Above-mentioned demarcation strip 6 can be designed to inverted V-shape.
In permanent magnetic roll assembly of roll magnetic separator A-A cutaway view shown in Figure 2, permanent magnetic roll assembly of roll magnetic separator is made of alternately a plurality of diameters identical toroidal magnet 8 and pure iron ring 9, they and 12 of mandrels are provided with magnetic shield 10, and establish every disk 11 reducing magnetic dispersion at the permanent magnetic roll assembly of roll magnetic separator two ends, and fixed with end plate 13.
Cut open along the A-A face in the partial enlarged drawing that shows at permanent magnetic roll assembly of roll magnetic separator shown in Figure 3, the magnetic polarity of the toroidal magnet 8 of pure iron ring 9 both sides is identical, and promptly N is extremely relative with the N utmost point, S and S, and the magnetic flux density of pure iron ring 9 is strengthened.Experiment detects and shows, this arrangement mode will make the magnetic induction intensity of the pure iron ring 9 outer rims arrangement mode more different than common polarity improve more than 50%.Therefore, the permanent magnetic roll assembly of roll magnetic separator volume of forming with this arrangement mode is little, in light weight, and magnetic induction intensity is also higher relatively.
In tripper B-B profile shown in Figure 4, tripper 5 is made up of row's chute shape passage, each chute passage is all aimed at the outer rim of the pure iron ring 9 of permanent magnetic roll assembly of roll magnetic separator 1, make material can relatively be evenly distributed on the conveyer belt of whole permanent magnetic roll assembly of roll magnetic separator, and make material concentrate the zone of dropping on the magnetic flux density maximum, to obtain best separating effect.
The conveyer belt of the utility model can adopt ultrathin wear-resisting adhesive tape, to reduce the replacing number of times of decay of conveyer belt Surface field and conveyer belt as far as possible.The toroidal magnet of the utility model can adopt permanent-magnet ferrite, to reduce the device fabrication cost.
