Description
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.
The objective of the invention is to improve the heat-conducting effect of deironing magnet exciting coil inside, it is little, in light weight to make tramp iron separator have a volume simultaneously, advantage such as low in energy consumption.
The present invention is achieved in that the magnet exciting coil in the tramp iron separator by the radially layered coiling, as the 2-6 layer, the heat pipe with high thermal conductivity is installed between every two-layer magnet exciting coil, props up as 2-20.Heat pipe is transmitted to the extexine of complete machine rapidly with a large amount of heats of magnet exciting coil inside, is diffused in the air, thereby reduces the temperature rise of magnet exciting coil.
Advantage of the present invention is: do not increasing under machine volume, power consumption and the weight situation, solved the internal temperature rise problem of the greatest problem-magnet exciting coil of tramp iron separator existence 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.
Structure of the present invention is described in conjunction with the embodiment accompanying drawing with inside and outside two-layer magnet exciting coil:
Fig. 1 be of the present invention just, vertical view.Fig. 2 is heat pipe structure figure of the present invention.
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 the 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 a 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 present invention vertically settles 2, one 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.
Fig. 2: be heat pipe structure figure of the present invention, 9-shell, 10-water, the 11-end socket, of the present invention is copper-water gravity heat pipe, and the upper end is a condensation segment, and the lower end is an evaporator section, shell 9 adopts the non-magnetic copper material, fine thread is made at the place at condensation segment, fully is contacted with the internal magnetic pole iron core so that install also, is to be the high vacuum situation in the shell chamber, inject high-purity water 10, at end socket 11 place's solder ups.
Heat pipe is to install like this: magnet exciting coil 3 and outer magnet exciting coil 1 two parts in magnet exciting coil is divided into, form a cannelure between inside and outside magnet exciting coil, the evaporator section of heat pipe lower end places this cannelure central authorities, with very little clearance for insulation of surface formation 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 other outer surfaces of complete machine again rapidly, be dispersed in the atmosphere through radiation and cross-ventilation again, thereby reduce the temperature rise of magnet exciting coil effectively.
All inject inserts 6 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 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 under the situation of not short circuit of external magnetic circuit.
Embodiments of the invention: as shown in drawings: appearance and size is: φ 700 * 460mm, weight is: 640 kilograms, exciting power: 1.37KW, 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, now enumerate several major technology indexs: be 1.37KW as exciting power the present invention, that Japanese is 1.8KW, but the iron-attracting performance aspect: to inhaling (6 * 100 * 100 millimeters on iron plate
3), suction iron height of the present invention is 310 millimeters, Japan be 300 millimeters, to inhaling (L40 * 40 * 150 millimeter, iron angle
3), suction iron height of the present invention is 370 millimeters, Japan be 330 millimeters etc.
