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 an iron removing equipment, in particular to a powder iron removing device. Background technique [0002] Iron separators are divided into electromagnetic separators and permanent magnet separators according to different sources of magnetic force. The electromagnetic separator is essentially a direct current electromagnet, and its excitation coil generates a strong magnetic field during the energization process to suck up the iron in the non-magnetic material. For example, an electromagnetic powder separator is disclosed in Chinese Patent Document CN1 01342515A . However, electromagnetic separators rely on current to generate a magnetic field, which consumes a lot of electrical energy during use, and its heat dissipation system also consumes energy. Permanent magnet iron remover is composed of high coercivity, high remanence rare earth magnetic material neodymium iron boron and ferrite magnetic source to form a strong magnetic f...

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
