Description

Large-scale self-cooling suspension type electromagnet iron separator

One, technical field

The utility model belongs to the suspended electromagnetic iron collector technical field, is specifically related to a kind of large-scale self-cooling suspension type electromagnet iron separator.

Two, background technology

At present, suspension type tramp iron separator both domestic and external can be divided into two kinds, electromagnetism, permanent magnetism by excitation mode.Permanent-magnetic iron expeller has that it is non-maintaining, the advantage of failure rate is low, but its magnetic field intensity is subjected to the restriction of magnetic material performance and cost can not do too greatly, and is therefore inapplicable for the demanding occasion of deironing.Electric magnetic iron remover can not be subjected to the restriction of magnetic field intensity but magnet exciting coil will produce heat in the process of energising, and for the dielectric strength of protecting coil, do not burnt, coil must be carried out heat radiation, cooling work, and temperature can not be too high.Therefore it is several that electric magnetic iron remover has had self cooling, air-cooled, water-cooled, oil cooling etc. on the type of cooling.Wherein water-cooled, oil cooling type electromagnetic diironing apparatus are to take away heat by cooling medium; Self cooling, air-cooled electromagnetic iron remover is to take away heat take air as medium by cross-ventilation.General compact electromagnetic tramp iron separator is because power is smaller, and is less demanding to dispelling the heat, so can the realizing of the various types of cooling.Yet large-scale electric magnetic iron remover is because its power is large, and very high to the heat radiation requirement, radiating condition must be fine.So the reasons such as the electric magnetic iron remover of self cooling form is poor because of its radiating effect, cooling effectiveness is low are difficult to use on large electromagnetic iron remover.Therefore, the large electromagnetic iron remover that uses at present adopts the higher water-cooled of cooling effectiveness, oil cooling or air-cooled methods for cooling more.But the electric magnetic iron remover of water-cooled, oil cooling or air-cooled form all need have an independent separately cover cooling system, if in case a bit little problem appears in its cooling system, complete machine even burns magnet exciting coil with regard to cisco unity malfunction, causes complete machine to scrap.

Three, summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, reasonable in design, good heat dissipation effect,

Cooling effectiveness is high, the suspended electromagnetic iron collector that self cooling form is applied on the large suspension-type electric magnetic iron remover.

For achieving the above object, the technical solution adopted in the utility model is: this tramp iron separator comprises iron core and is wrapped in the coil in its outside, and iron core and coil are surrounded with the base plate of the yoke plate of hanger, bottom and the magnetic conductive board in the outside by top; Be characterized in: the barrel-shaped coil that described coil does not wait for several diameters, leave air flue between coil, be provided with respectively a plurality of ventholes and sidepiece air admission hole in the upper and lower part of magnetic conductive board, be provided with a plurality of lower air inlet in the bottom of base plate, sidepiece air admission hole and lower air inlet communicate with venthole through air flue.

The utility model is owing to being provided with air flue between each barrel-shaped coil, and heat will reduce greatly from the middle thermal resistance that is transmitted to the surface of coil, and the cooling surface area of coil has increased by 3-4 times, has improved radiating effect.Simultaneously, when entering coil from bottom to top due to cold air, to be entered simultaneously by sidepiece air admission hole and lower air inlet, increased the intake of cold air, add the effect of the long and narrow air flue between coil, make the flow velocity of cold air be greatly improved, can take away more heat, self cooling form is applied on the large suspension-type electric magnetic iron remover becomes possibility, thus the problems of having avoided water-cooled, oil cooling or air-cooled form to exist.

The utility model is simple in structure, reasonable in design, and cooling effectiveness is the self cooling electric magnetic iron remover of traditional type more than 2 times, and its magnetic field is strong, and good iron removal effect is safe and reliable to operation, and fault is few, and maintenance cost is very low.

Five, the specific embodiment

As shown in the figure, the utility model comprises iron core 1 and is wrapped in the coil 3 in its outside, and iron core 1 and coil 3 are surrounded with the base plate 5 of the yoke plate 2 of hanger 10, bottom and the magnetic conductive board 4 in the outside by top.Iron core 1, yoke plate 2 and magnetic conductive board 4 consist of E type magnetic circuit, and wherein iron core 1 is made by electrical pure iron.Coil 3 is the slim barrel-shaped coil that four diameters do not wait, and besieges it ring upon ring the outside that is distributed in iron core 1, and this coil 3 is fixed on yoke plate 2 by steel bar connecting plate 9, leaves air flue 12 between coil 3.Adopting the slim barrel-shaped coil of this kind and many air passage structures, both increased the area of dissipation of coil 3, reduced again the consumption of coil 3, is only original 50% left and right, greatly reduces manufacturing cost, has also alleviated the deadweight of coil 3.Be provided with respectively a plurality of ventholes 8 and sidepiece air admission hole 7 in the upper and lower part of magnetic conductive board 4.Base plate 5 adopts nonmagnetic substance to make, and its underpart is provided with a plurality of lower air inlet 6.This lower air inlet 6 is radial cirque structure, and corresponding with the air flue 12 between coil 3, makes Air Flow more unimpeded.Magnetic iron bar 11 is housed on air admission hole 6, when have little ironware impurity want by lower air inlet 6 access arrangements in the time, small iron element can be adsorbed by magnetic iron bar 11, can prevent effectively that small iron element from entering in coil 3, prevents that coil 3 from burning.Sidepiece air admission hole 7 and lower air inlet 6 communicate with venthole 8 through air flue 12.
