Knowledge of electromagnetic iron removers
Electromagnetic iron remover is a new type of iron remover developed with the development of rare earth technology in China. China has a wide range of rare earth resources, and the development and application of all kinds of rare earth permanent magnet materials are very rapid. Permanent magnet iron removal according to the way can be divided into belt automatic iron unloading, plate artificial iron unloading, manual iron unloading and flipping plate type iron unloading 4 categories. In addition, there are pipe type, grid type, grid type, permanent magnet drum, drum and so on.
(1) belt type electromagnetic iron remover. The belt permanent magnet iron remover is characterized by automatic iron discharge, constant magnetic field, no change of cold and hot state, less fault points, and is widely used in the bandwidth of less than 1 200 mm. At present, the development of magnetic shielding technology is not good, so it brings a lot of trouble to manufacturing, transportation, installation, operation and maintenance. For example, large pieces of iron are sucked onto the magnetic box, which may not be thrown off, thus clamping the belt and burning the motor. At the same time, it is difficult to remove, and may cause damage to the magnetic block, so it is limited in the application of large specifications.
(2) plate artificial iron discharge type electromagnetic iron remover. In addition to all iron tools for simple, low price, small space, convenient manufacturing installation and maintenance. Can be divided into two kinds roughly according to configuration way, namely suspension fixed and bottom fixed. The hanging fixed plate iron remover is suitable for installation on the upper part of the belt conveyor, and the bottom fixed plate iron remover is suitable for installation under the lower hopper or chute. This type of iron removal equipment is suitable for small iron impurities, less occasions, and the conveying material flow thickness is not more than 100 mm. When the equipment is working, the iron inclusion is directly attracted to the magnetic plate, which requires regular manual unloading, which is more laborious.
(3) manual electromagnetic iron remover. Manual permanent magnet iron discharge in addition to the use of shaking hand scraper scraper iron pieces to the magnetic field in addition to the way of iron, but generally can not be used for large iron occasions.
(4) flip plate type electromagnetic iron remover. Flipping plate type permanent magnet iron remover when unloading the magnetic system will flip about 9O. Make the ferromagnetic material automatically fall off, its shape has the structure of lifting the magnetic system out of the magnetic field (drawer type), its shape size is shorter than the length of the belt type, slightly higher height, more convenient and simple operation.
(5) Pipe type electromagnetic iron remover. Pipe iron remover is a kind of iron removal equipment for wet operation. The device mainly consists of a magnetic rod inserted into a pipe. The equipment is suitable for removing iron in slurry, especially for removing fine particles of iron. Mainly used for cement, food, glass, chemical and other industries in addition to iron, its simple structure, but generally for artificial iron unloading (there are also pipe electromagnetic iron removal device). Its structure is ① in addition to the iron external type in addition to the iron attached to one side or both sides of the pipe (general pipe is rectangular); (2) iron remover built-in iron remover is conical in the middle of the pipe (general pipe is round).
(6) Grid type permanent magnet iron remover. The iron remover is made of multiple magnetic bars spaced apart. As a guide plate is placed above the grid, it increases the probability that the iron inclusion in the material will be attracted by the magnetic bar. In order to make the device suitable for different feeders, the device can be customized into circular lattice and square lattice according to user requirements. The device is suitable for removing iron from materials below 12.5mm.
(7) grid type electromagnetic iron remover. Generally tubular, using extrusion magnetic field layout, can be used for dry iron removal, and can be made into wet pipe iron removal device. Mainly used for chemical raw materials, pulp, minerals and other raw materials in the removal of impurities, high magnetic field intensity, large gradient, but small depth, poor uniformity.
(8) channel type electromagnetic iron remover. This iron eliminator is mainly composed of two magnetic plates combined by the frame. The channel frame is also above With a guide plate, the iron removal rate of the material can reach. The advantage of the device is that the mechanical iron in the block (5O ~ 60mm) can be fully and effectively removed.
(9) Electromagnetic iron remover. It consists mainly of a multi-fixed magnetic system and a cylinder made of a non-magnetic material. The inclusion Angle of the fixed magnetic system is 180. Or 360. , the cylinder rotates around the magnetic system or the entire magnetic drum. Generally can be used to replace the belt conveyor driving wheel, not only can drive the belt conveying materials, but also play the role of separation, in the steel slag recycling, mining iron sand and gravel rough selection, non-magnetic material in the removal of miscellaneous plays an important role, simple operation. The equipment is suitable for the removal of iron in the conveying process of coarse particle materials below 50 mm.
(1O) Electromagnetic iron remover. The magnetic system and drum structure of the equipment are basically the same as that of the drum iron remover mentioned above. The difference is that the drum is driven by an independent motor, so continuous and independent iron removal can be carried out. It is very suitable for removing iron in material flow with large iron content.
