Abstract
The utility model relates to a suspension type permanent magnetism iron remover, which comprises a frame, a magnetic disk, a motor, a transmission system and scraping strips which are fixed on a belt. The utility model is characterized in that the magnetic disk adopts a permanent magnetic core and is fixed on the frame, the motor, the transmission system, a driving roller and a driven roller drive the belt and the magnetic disk to rotate, and thus a permanent magnetism iron remover which adopts a structure of permanent iron attraction and automatic iron unloading is formed. The utility model has the advantages of simple structure, small size, energy saving, large gradient of the magnetic field, strong magnetism attraction ability, high reliability and high work efficiency, and the utility model can achieve excitation without energization and running free of faults.
Description
The utility model belongs to the magnetic deironing equipment technical field, is applied to industries such as coal-burning power plant, coal, mine, metallurgy, and with ribbon conveyer, supporting use such as jigging conveyer can be removed the ferromagnetism article in the shape non-magnetic material that looses.
The tramp iron separator of present industrial application mainly contains following two kinds of forms: the one, and the disc type electric magnetic iron remover, its operation principle is: electromagnetic disc is suspended on the conveyer belt, the input AC electric current is rectified into direct current by switch board, produce magnetic field by the coil in the electromagnetic disc again, iron core magnetization forms big magnetic field below electromagnetic disc, when have on the conveyer belt ironware by the time be adsorbed under the electromagnetic disc, lose magnetism during power failure, manually remove when ironware falls; The 2nd, the belt electric magnetic iron remover, its operation principle is that electromagnetic disc is mixed framework and is furnished with drive motors and belt, and ironware is adsorbed on the electromagnetic disc below, and the shelves bar scraped ironware when belt rotated, thereby realized automatic iron removing.The tramp iron separator of these two kinds of forms all need be furnished with rectifier cabinet, and burns coil and must pass to little electric current sometimes in order to prevent that temperature from raising; Perhaps need dispose metal detector, discontinuous work.The former, magnetic field is little, iron-attracting performance is poor, and de-ferrous effect is bad; The latter, the metal detector fault is many, and functional reliability is poor.And all there is a not problem of easy care of rectifier cabinet.
The utility model provides a kind of suspension type forever to inhale iron and unloads the iron permanent-magnetic iron expeller automatically, and this tramp iron separator is simple in structure, and the excitation no power is saved a large amount of energy.
The utility model is achieved in that permanent-magnetic iron expeller comprises framework, disk, motor and transmission system and is fixed on scraping article on the belt, it is characterized in that disk adopts resident core to be fixed on the framework by yoke, motor and transmission system and drive roll, driven drum driven belt turn round around disk, thereby constitute the permanent permanent-magnetic iron expeller that iron unloads iron construction automatically of inhaling.
The utility model is simple in structure, size is little, and the reliability height is applied widely, and the excitation no power is saved a large amount of energy, and maintenance is few.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The utility model has on framework 1, disk, motor and transmission system 5, drive roll 2, driven cylinder 9, scraping article 4, carrying roller 6, the belt 7 and is fixed with scraping article 4, so just formed and had permanent suction iron and unload the permanent-magnetic iron expeller of iron function automatically, it is high performance permanent magnet 11 to be placed be fixed on yoke in the stainless steel case 10 with magnetic pole gap 12 and be formed with certain interval 3 times that this tramp iron separator adopts resident core, its resident core, and be the N of independent completion, the high-intensity magnetic field of two magnetic poles of S, the magnetic pole gap 12 of the resident core of this tramp iron separator should be parallel to belt 7.Resident core should form N, two magnetic poles of the S utmost point and be fixed on the framework 1 by yoke 3, and yoke 3 must be enough thick, and its thickness should guarantee that yoke passes through the ability of bipolar magnetic flux, and its thickness should be 20--150mm.Permanent magnet 11 can adopt the Fe-B rare-earth permanent magnet of high energy product, high-coercive force, also can adopt the ferrite of high energy product, high-coercive force.The motor of this tramp iron separator should be arranged in the top of framework 1, and drive roll 2 and driven cylinder 9 should be near permanent magnetism core both sides, and the diameter of drive roll 2 and driven cylinder 9 is 270-325mm.The length of whole like this tramp iron separator only be equivalent to same specification the belt electric magnetic iron remover 2/3rds in so that be fit to be installed in more conditions.Hang for convenient in the use, on the framework 1 of this tramp iron separator, should be provided with hanger 8.The permanent-magnetic iron expeller of making like this during work is suspended on it top of conveyer belt.When the diffusing shape non-magnetic material on the conveyer belt during through the permanent-magnetic iron expeller below, be mingled in ironware in the material under the effect of this tramp iron separator strong magnetic field power, adsorbed by resident core across belt 7.The commentaries on classics because belt 7 is not stopped transport, the scraping article 4 that is fixed on the belt 7 constantly scrapes the ironware of absorption, thereby reaches the purpose of automatic iron removing.
The utility model is compared with the like product of prior art has following advantage: one, permanent magnet 11 becomes two magnetic poles of N, S by yoke 3 with the stainless steel box-shaped, and magnetic field gradient is big, and suction is strong; Two, no power excitation, corollary apparatus are few, the reliability height, and failure-free operation is easy to safeguard; Three, save a large amount of energy; Four, motor is placed in the middle of the framework 1, drive roll 2, and driven cylinder 9 is close to resident core, and compact conformation, tramp iron separator length shorten dramatically, and it is little to take up room; Five, suction is untouchable bigger, is equivalent to electric magnetic iron remover more than four times, and the complete machine iron-attracting performance is four times of electric magnetic iron remover.
