Description

Permanent-magnet high-gradient magnetic seperator

The utility model relates to a kind of permanent magnet high gradient magnetic separator, belongs to the magnetic separating apparatus class of separating solids material from fluid.

In order from magnetic mud, to remove undesirable iron, impurity such as titanium, people have developed all kinds of magnetic separators, as adopt the magnetic separator of electric excitation, but it is big that this equipment produces the magnetic field intensity power consumption, the equipment investment height, along with the permanent-magnet material that magnetic energy product improves constantly is come out one after another, people set about developing high performance magneto magnetic separator, PERMOS(R as German KHD flood fort one Veda lattice AGCO development) cartridge type permanent magnetic separator, the cartridge type permanent magnetic motor that Britain BOXmag-ripid company produces, domestic as 92212042.0 magnetos practical novel patent gazette bulletin on July 1st, 1992 are arranged iron mud magnetic separator automatically, the 91218512.0 permanent magnetic pulley ring type separators that on September 30th, 93 was announced, the magnetic field gradient of this class permanent magnetic motor is not enough, thereby can not effectively remove the microfine impurity of μ m level in the ore pulp.

The purpose of this utility model provides a kind of magnetic separator that adopts permanent-magnet material and use can produce the high magnetic field gradients magnetizing mediums, both can remove the fine impurity of μ m level in the ore pulp, can save electric energy again.

The purpose of this utility model is to adopt following manner to realize, being provided with the closed magnetic that produces high field intensity in ore pulp branch constituency is, the sorting band of being made up of the medium bag passes through the branch constituency, the medium magnetization, catch magnetic impurity in the ore pulp, take the discharging of branch constituency out of, also be provided with some auxiliary equipments, to strengthen sorting and impurities removal effect.

Advantage of the present utility model is:

1, energy-conservation, the electromagnetic magnetic magnetic separator economize on electricity that has equal sorting function is more than 70%, and water saving is more than 30%, and the short of electricity district also can adopt manpower.

2, weight of equipment is light, and ton machine disposal ability is big, is more than the twice of electromagnetic type, can reach 2～8 tons of (ore deposit)/h tons (machine is heavy).

3, cost is low, only is about 1/10 of electromagnetic type.

4, capital expenditure is few, only is 1/5～1/2 of electromagnetic type.

5, good separation effect is containing Fe ₂O ₃Be the Fe after 0.21% the former glaze sorting ₂O ₃Can drop to 0.17%, the de-iron rate reaches 19.7%, the electromagnetic type de-iron device that existing each porcelain factory uses less than 1%; Separate pug-porcelain blank raw material, contain Fe ₂O ₃Be 0.779% raw material, can drop to 0.67%, the de-iron rate is 15.1%.And the de-iron rate of the electromagnetic magnetic magnetic separator of 0.3～0.5 special magnetic induction only is 9.93%.

The magnetic impurity that the utility model also can be used for some other metal and non-metallic material separates, sewage disposal, produces magnetized drinking water, makes magnetic fertilizer, magnetised feed or magnetized food etc.

Embodiment of the present utility model is provided by accompanying drawing, and Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is a sorting band schematic diagram, Fig. 3,4 is for closed magnetic is, open circuit magnetic is schematic diagram, Fig. 5 is for giving the chinaware schematic diagram, and Fig. 6 is for agitating the device schematic diagram, and Fig. 7 hits the device schematic diagram for medium Bao Qing.

Further specify structure of the present utility model below in conjunction with accompanying drawing.

With reference to accompanying drawing, the utility model comprises sorting band 1, feed hopper 2, last magnetic pole 3, rinse bath 7, support 8, crossbeam 9, lower magnetic pole 10, sorting box 11, first running roller 14, tail running roller 6, sorting band are contained on first running roller 14 and the tail running roller 6, be connected with several on the sorting band medium bag by the magnetizable medium of certain regularly placing is housed, the sorting box is permanent-magnet material hollow, that periphery has south, the arctic to settle relatively, as ndfeb magnetic pole, to form the background magnetic field that divides 0.4 tesla in the constituency.

Magnetic impurity is that example illustrates its course of work in the ore pulp to separate below:

Start back ore pulp injects from feed hopper, the sorting band of the reverse movement of flowing through, and the sorting band drives motion by first running roller, when passing the sorting box, magnetizable medium is magnetized in the medium bag, thereby catches magnetic impurity in the ore pulp, and its band separated selects box, concentrate slurry after the sorting is discharged through discharge pipe 5, the sorting band cleans in rinse bath, and magnetic impurity is discharged by the rinse bath low side, thereby finishes assorting room, for improving the task performance of this magnetic separator, following devices need be installed also:

1, give chinaware, material be housed on the charging aperture of feed hopper give chinaware 2, give chinaware and be the like pole facing each other of mail packing, be sleeved on the slurry pipe, mineral aggregate is given magnetization after, produce " magnetic extruding " effect, to improve separating effect greatly.

2, water jet is equipped with the water jet 15 of adjustable angle above the head and the tail running roller, rotate in many ways with the cleansing medium bag.

3, medium Bao Qing hits device and agitates device 12.Be installed in the rinse bath 7, hitting device clearly is a motor-driven or manual impeller, when the medium bag through out-of-date, blade repeated bump medium bag is thoroughly to wash medium impurity that bag is taken.Be thorough cleansing medium bag, also can adopt and agitate device that the device of agitating that is installed in the rinse bath is made up of connecting rod, eccentric wheel and solicitating film, make rinse water impulse medium bag and cleaned.

4, divide constituency gradient adjusting device, traditional magnetic separator does not have gradient adjusting device, and the slip flow velocity is controlled by feed pump.The utility model is provided with lifter 13 on support, so that adjustment divides the constituency gradient, changes material flow according to different situations.

5, vibrator is equipped with vibrator at sorting box tail end, and promptly solenoid 4, makes it to make the vibration of sorting box with the permanent magnetic field effect, impels material to disperse, in order to sorting.
