永磁除铁器的具体卸铁方式分类和应用

Classification and application of specific unloading methods of permanent magnet iron remover

   永磁除铁器内部采用高矫顽力，高剩磁的特殊永磁体“钕铁硼”等材料组成复合磁系。具有免维护、磁力强、寿命长、安装简单、使用方便、运行可靠等优点。

The composite magnetic system is composed of NdFeB, a special permanent magnet with high coercivity and high remanence. The utility model has the advantages of maintenance-free, strong magnetic force, long service life, simple installation, convenient use and reliable operation.

适用于皮带机、振动输送机、电磁振动给料机、下料溜槽上的非磁性物料中除铁。

It is suitable for removing iron from non-magnetic materials on belt conveyor, vibration conveyor, electromagnetic vibration feeder and discharge chute.

清除0.1～35公斤的铁磁性物质，内部永磁磁系使用寿命10年以上。 当永磁铁吸附铁磁物较多时，人工用非磁性刮板清除或戴手套摘除，适用于连续工作，含铁较少的场合。

Removal of 0.1-35 kg of ferromagnetic material, internal permanent magnet system service life of more than 10 years. When there are more ferromagnets adsorbed by permanent magnets, manual removal with non-magnetic scrapers or gloves is suitable for continuous work with less iron.

永磁除铁器是以高矫顽力、高剩磁的稀土磁性材料钕铁硼和铁氧体组成磁源，以形成强力磁场，用于吸除铁磁性杂物，整机不通电，无能耗。永磁除铁器按卸铁方式可分为自动卸铁、人工卸铁、手动卸铁等。

Permanent magnet iron remover is a magnetic source composed of Nd-Fe-B and ferrite, a rare earth magnetic material with high coercivity and remanence, to form a strong magnetic field, which is used to absorb ferromagnetic impurities. The whole machine is not electrified and has no energy consumption. Permanent magnet iron remover can be divided into automatic iron unloading, manual iron unloading, manual iron unloading and so on.

永磁除铁器的具体卸铁方式分类和应用如下?

The specific ways of unloading permanent magnet iron remover are classified and applied as follows?

(1)带式永磁除铁器。带式永磁除铁器特点是自动卸铁， 磁场恒定， 无冷热态变化， 故障点少，在 1200 mm 带宽以下应用较普遍。由于目前磁屏蔽技术发展还不过关， 所以给制造、运输、安装、操作、维修均带来不少麻烦。

(1) Belt permanent magnet iron remover. Belt permanent magnet iron remover is characterized by automatic iron unloading, constant magnetic field, no cold and hot state changes, fewer fault points, and is widely used below 1200 mm bandwidth. At present, the development of magnetic shielding technology has not passed the standard, so it brings many troubles to manufacture, transportation, installation, operation and maintenance.

例如大块铁被吸上磁箱存 在着既有可能抛不掉，从而夹死皮带烧毁电机的问题。同时又难以清除，并有可能 对磁块造成损坏，因而在大规格的应用上受到一定的限制。

For example, there is a problem that large iron can not be thrown away when it is absorbed into the magnetic box, and the belt can be clamped to burn the motor. At the same time, it is difficult to remove, and may cause damage to the magnetic blocks, so the application of large specifications is limited.

(2)人工卸铁式永磁除铁器。在所有除铁器中最为简单，价格低，占用空间位置 小，制造安装维修方便。按照配置方式大致可分为两种，即悬挂固定式和底部固定 式。悬挂固定板式除铁器适于安装在胶带输料皮带机的上方，而底部固定板式除铁 器适于装在下料斗或溜槽的下方。

(2) Artificial iron-unloading permanent magnet iron remover. In all iron removers, it is the simplest, the price is low, the occupied space is small, and the manufacture, installation and maintenance are convenient. According to the configuration, it can be roughly divided into two types: suspension fixed type and bottom fixed type. The suspended fixed plate iron remover is suitable for mounting above the belt conveyor, while the bottom fixed plate iron remover is suitable for mounting below the hopper or chute.

这种类型的除铁设备适于含铁杂质较小、较少的场合，而且输送料流厚度最好不超过 100 mm。该设备工作时，夹杂铁物直接被吸引 在磁力板上，需进行定期人工卸铁，较为费力。

This type of iron removal equipment is suitable for occasions with less iron impurities, and the conveying material flow thickness should not exceed 100 mm. When the equipment works, the inclusions of iron are directly attracted to the magnetic plate, which requires regular manual iron unloading, which is more laborious.

(3)手动式永磁除铁器。手动式永磁除铁器卸铁时采用摇手把利用刮板将铁件刮到磁 场外的方式 进行除铁，但一般还不能用于有较大铁件的场合。

(3) Manual permanent magnet iron remover. Hand-operated permanent magnet iron remover removes iron by shaking handle and scraping iron into magnetic field with scraper, but it can not be used in occasions with larger iron parts.
