Description
One, technical field
The utility model belongs to magnetic plant, is specifically related to a kind of electric magnetic iron remover.
Two, background technology
As everyone knows, the de-ferrous effect of tramp iron separator is by the size decision in the magnetic field in deironing district.Electric magnetic iron remover the time can produce a large amount of heats in work, as can not efficiently radiates heat influencing the life-span and the dependability of equipment.That existing electric magnetic iron remover heat radiation mainly contains is air-cooled, oil cooling, several modes such as self cooling.Owing to the restriction of tramp iron separator heat radiation power P is arranged, its exciting power P '=I
2R must not surpass heat radiation power P, causes common tramp iron separator to improve electric current and is restricted, thereby can't produce bigger magnetic field.
In recent years, the production of superconductor and related application technology are day by day ripe, have reached the level that can be applicable in the industrial production.The resistance of superconductor under critical-temperature is 0, and strengthen electric current and can not produce heat this moment, almost do not had the restriction to electric current.The size in magnetic field is directly proportional with the product of coil turn and electric current, because the restriction that has not had electric current to improve, the superconduction tramp iron separator can obtain very strong magnetic field.Along with manufacturing enterprise to improving gradually of requiring of tramp iron separator energy-conserving and environment-protective with to the increasingly stringent of de-ferrous effect, develop a kind of energy-conserving and environment-protective and have the tramp iron separator of superpower de-ferrous effect that very big necessity has just been arranged.
For example transport in the belt conveyer of boats and ships harbour at coal, general belt width broad, material thickness is thicker, and the speed of belt feeder is very fast, uses general tramp iron separator to be difficult to and can to satisfy the demands.In the coal as contain harmful ironware such as detonator, effectively deironing is just blasted easily in case advance stove.In order can better iron things such as detonator to be removed, need a kind of equipment for removing ferric ion of large-scale strong magnetic.And to reach de-ferrous effect preferably, the magnetic field of coal conveyer belt bottom should reach 5000GS, coal conveyer belt with 2 meters bandwidth is an example, the tramp iron separator bottom will remain on more than the 550mm apart from the belt bottom at least, if and conventional electric magnetic iron remover wants that the 550mm place realizes that the magnetic field of 5000GS is impossible almost just below the tramp iron separator bottom surface, computing equipment weight is more than 100 tons, and power consumption surpasses 300KW; And superconduction tramp iron separator weight of equipment only is 5 tons, the not enough 10KW of total power consumption.The later stage energy loss that conventional electric magnetic iron remover is manufacturing cost or user is all high a lot of than superconductivity electric-magnetic iron remover.
Three, summary of the invention
The purpose of this utility model provides a kind of superconductivity electric-magnetic iron remover, can be suitable for all-environment deironing work, more efficiently the iron foreign material in the sucking-off material.
The technical solution of the utility model is: superconductivity electric-magnetic iron remover comprises magnetic system, drive system and control system, and the electromagnetism winding coil in the magnetic system is made by superconductor; In the coil outside heat insulation layer is arranged; Refrigeration machine is installed on the tramp iron separator, and superconducting coil is connected with the cold head of refrigeration machine.
The course of work of the present utility model is as follows: integral device is by the charged excitation of superconducting coil, makes superconducting coil remain on the required superconducting temperature of superconducting wire by refrigeration machine, the almost noenergy loss of excitation process.The coil outer wrapping vacuum heat-insulating layer, owing to be high vacuum in the heat insulation layer, coil blocks the heat exchange of outer bound pair coil by heat insulation layer.The tramp iron separator that has magnetic field will pick up through the irony thing of its field regions to realize the purpose of final deironing.
Superconductivity electric-magnetic iron remover is compared with conventional electric magnetic iron remover and has been possessed following obviously advantage:
(1) superconducting magnet of superconductivity electric-magnetic iron remover does not almost have the Joule heat loss, be easy in bigger space, obtain very strong magnetic field, can be easy to make the ferrum property that removes of tramp iron separator to improve more than four times, reach the conventional tramp iron separator performance indications that are beyond one's reach, and then realize satisfying strict more deironing requirement by the de-ferrous effect that conventional tramp iron separator can't be realized.
(2) volume is little, in light weight.Because the current density of superconductor can reach more than 400 times of conventional self cooling tramp iron separator, and winding volume can drop to below 1/400 of self cooling tramp iron separator of identical performance, even comprise that chilling unit is also light than the self cooling electric magnetic iron remover with performance, tangible volume and weight advantage arranged in the tramp iron separator of large-scale strong magnetic especially.
(3) good operation stability.Because superconducting magnet can be moved under short circuit current for a long time constantly, therefore has very high time stability, magnetic field intensity does not have any variation with the operation duration of equipment, and being different from conventional electric magnetic iron remover magnetic field intensity can reduce with the growth of running time.
(4) operating cost is cheap.One-shot, the energy long-term operation, run duration does not almost have thermal losses, adds that the operate power of compressor and refrigeration machine generally can not surpass 10KW yet, and tangible power savings advantages is arranged in the tramp iron separator of large-scale strong magnetic especially.
The utility model makes de-ferrous effect that the raising of jumping property arranged, and operating cost has had significantly reduction, also will reduce to minimum by the potential safety hazard that the irony foreign material bring simultaneously.From the angle of development, superconductivity electric-magnetic iron remover will be the renewal product of conventional electric magnetic iron remover, is the inevitable development direction of tramp iron separator manufacturing technology.
