Apparatus for removing iron in powder

Abstract

The invention relates to an apparatus for removing iron in powder. The apparatus comprises a feeding mechanism, a magnetic separation mechanism and a support; the magnetic separation mechanism comprises a box, at least a magnetic rod set, magnetic rod sleeves with an amount corresponding to the amount of magnetic rods, a magnetic rod set driving unit and a flap valve, wherein, the magnetic rod sleeves are transversely arranged at the middle and upper parts of the box, one end of every magnetic rod of the magnetic rod set is fixed by a connection board and is then connected with a power output terminal of the magnetic rod set driving unit, the other end of every magnetic rod passes through a corresponding magnetic rod sleeve, every magnetic rod slidely moves in its corresponding magnetic rod sleeve under the driving of the magnetic rod set driving unit, an iron discharging outlet and a material discharging outlet are arranged at the bottom of the box, and the flap valve is installed above the iron discharging outlet and the material discharging outlet. The apparatus has the following advantages: a good iron-moving effect, low energy consumption, low cost for operation and maintenance, particular suitability for fine removal of iron in a powder material, a simple structure, small occupation space, convenient fabrication, installation and maintenance, a low price and easy popularization and usage.

Description

technical field [0001] The invention relates to iron removal equipment, in particular to a powder iron removal device. Background technique [0002] According to different sources of magnetic force, iron remover can be divided into electromagnetic iron remover and permanent magnet iron remover. The electromagnetic iron remover is essentially a DC electromagnet, and its excitation coil generates a strong magnetic field during the electrification process to attract iron parts in non-magnetic materials. For example, an electromagnetic powder iron remover is disclosed in Chinese patent document CN1 01342515A . However, the electromagnetic separator relies on electric current to generate a magnetic field, which consumes a large amount of electric energy during use, and its cooling system also consumes energy. The permanent magnetic iron remover is composed of rare earth magnetic materials NdFeB and ferrite with high coercive force and high remanence as a magnetic source to fo...

AI Technical Summary

Problems solved by technology

However, the electromagnetic separator relies on current to generate a magnetic field, which consumes a lot of power during use, and its cooling system also consumes energy.

The permanent magnetic iron remover is composed of rare earth magnetic materials NdFeB and ferrite with high coercive force and high remanence as a magnetic source to form a strong magnetic field for absorbing ferromagnetic debris. The whole machine is not powered on and has no energy consumption. , but the existing iron removal devices of this type are not only complex in structure, but most of them are difficult to apply to iron removal of powder materials. A large waste of raw materials; the structure of the pipeline type iron remover can not completely disperse the powder, the efficiency of iron removal is low, and a large amount of powder is carried into the tap hole
