Description

Hang tupe electric-magnetic iron remover

A kind of suspended electromagnetic iron collector is a kind of dc electromagnetic device.

General electric magnetic iron remover claims locking magnet again, or electromagnetic separator, and (abbreviation tramp iron separator) hangs on belt conveyor line middle part or above-head with it, by means of powerful magnetic force, with the rapid sucking-off of ferromagnetism object of sneaking in the nonmagnetics materials flow.It can be widely used in industries such as mine, electric power, metallurgy, casting, chemical industry, building materials, printing and dyeing, food.

Existing electric magnetic iron remover, slap several parts and form by magnet exciting coil, interior magnetic iron core, outer yoke, non-magnetic conduction chassis, the utmost point, it exists a bigger problem to be: when passing through magnet exciting coil owing to electric current, a large amount of heat energy have been produced, it makes the tramp iron separator internal temperature rise too high, and influence the de-ferrous effect of tramp iron separator, and reduce greatly its service life.For addressing this problem, existing tramp iron separator adopts two kinds of versions, the one, force methods for cooling, promptly air blast is installed at outer yoke metallic object one end, the other end has the air-out window, be provided with cooling ventilation duct in the magnet exciting coil, this form is effective to reducing the tramp iron separator internal temperature rise, but bring power consumption to increase, defective such as noise increases, and machine volume is bigger than normal, simultaneously, when wind is squeezed into the magnet exciting coil surface, also bring a large amount of environment dust and pernicious gas into, thereby quickened the aging of internal insulator and destroyed the service life of reduction complete machine.Another kind is totally-enclosed natural methods for cooling, and internal heat does not adopt any other heat conduction and heat radiation measure by integral surface heat radiation cooling, must increase the weight and the complete machine size of magnet exciting coil largely, and this structure production cost height is difficult to actual production.

Advantages such as the purpose of this utility model is to improve the heat-conducting effect of tramp iron separator magnet exciting coil inside, and it is little, in light weight to make tramp iron separator have a volume simultaneously, low in energy consumption.

The utility model is achieved in that the magnet exciting coil in the tramp iron separator is divided into interior magnet exciting coil and outer magnet exciting coil two parts, installation one has the heat pipe of high thermal conductivity between inside and outside magnet exciting coil, heat pipe is transmitted to a large amount of heat energy of magnet exciting coil inside the extexine of complete machine rapidly, be diffused in the air, thus the temperature rise of reduction magnet exciting coil.

The utility model has the advantages that: do not increasing under machine volume, power consumption and the weight situation, solved greatest problem---the internal temperature rise problem of magnet exciting coil that tramp iron separator exists effectively, make designed tramp iron separator have that iron-attracting performance is strong, volume is little, in light weight, energy consumption is low, noiselessness, cost are low, simple in structure, cooling and can be applicable to characteristics such as work under the various adverse circumstances naturally.

Detailed structure of the present utility model is described in conjunction with the accompanying drawings:

Accompanying drawing be of the present utility model just, vertical view.

Among the figure: the outer magnet exciting coil of 1-, magnet exciting coil in the 2-heat pipe, 3-, 4-internal magnetic pole iron core, 5-outer yoke, 6-inserts, the non-magnetic conduction of 7-chassis, the 8-utmost point palm.

The magnetic system of this electric magnetic iron remover adopts concentric structure, an end that is magnetic pole is columniform internal magnetic pole unshakable in one's determination 4 and the utmost point palm 8, the other end of magnetic pole is the outer yoke metallic object 5 of annular, two magnetic poles are connected to form internal magnetic circuit by internal magnetic pole top unshakable in one's determination, external magnetic circuit is lower space, this space can produce a powerful non-uniform magnetic-field under the effect of magnet exciting coil, utilize the high gradient characteristic of this non-uniform magnetic-field can pick up the ferromagnetic material that is mingled in the non-magnetic material. The magnet exciting coil of tramp iron separator places between internal magnetic pole iron core and the outer yoke metallic object. For a large amount of heat energy that the tramp iron separator magnet exciting coil is produced when working promptly are delivered to this machine outer surface heat radiation, reduce the magnet exciting coil temperature rise, the utility model vertically settles 2-20 braces that the heat pipe 2 of high thermal conductivity is arranged in this machine magnet exciting coil interior temperature distribution highest region territory, said heat pipe adopts copper-water gravity heat pipe, and its heat conductivility is best.

Heat pipe is to install like this: magnet exciting coil is divided into interior magnet exciting coil 3 and outer magnet exciting coil 1 two parts, form a cannelure between inside and outside magnet exciting coil, the evaporator section of heat pipe lower end places this cannelure central authorities, forms a very little clearance for insulation with the surface of inside and outside magnet exciting coil; Heat pipe upper end condensation segment is installed in internal magnetic pole top unshakable in one's determination with long fine thread connection form, when a large amount of heat energy of magnet exciting coil inside promptly are delivered to internal magnetic pole top unshakable in one's determination by heat pipe after, heat energy diffuses to rapidly again other outer surfaces of complete machine, be dispersed in the atmosphere through radiation and cross-ventilation again, thereby effectively reduce the temperature rise of magnet exciting coil.

All inject in the clearance for insulation of heat pipe and inside and outside magnet exciting coil and in the every other gap of tramp iron separator, inserts 6 with electric insulation and good heat conductivity, on the chassis 7 that non-magnetic has been installed in the tramp iron separator bottom, it can make the tramp iron separator integral sealing in the situation of not short circuit of external magnetic circuit.

Embodiment of the present utility model: as shown in drawings: appearance and size is: φ 700 * 460mm, weight is: 640 kilograms, exciting power: 1.35KW, the use DC voltage is: 220 volts, inhale iron apart from the 150-200 millimeter, it can effectively absorb the ferromagnetic material in the non-magnetic material on the belt conveyor, but continuous operation, this product is through the operation test shows, its performance has surpassed Japanese product index of the same type, and now enumerate several major technology indexs: as power the utility model is 1.35KW, and that Japanese is 1.8KW, but iron-attracting performance aspect: concerning inhaling iron plate, suction iron height of the present utility model is 310 millimeters, and Japanese is 300 millimeters, concerning inhaling the iron angle, the utility model is 370 millimeters, Japan be 330 millimeters etc.
