Problems solved by technology

The disadvantages are: 1. Due to the use of a single magnetic core, the area and time of its magnetic field action are limited, and the removal effect of iron in the material on the conveyor belt with a high belt speed and a relatively thick material layer is poor.
Especially when removing slender rods such as bolts for downhole use, since they can only generate a single magnetic field, the two ends of the long piece cannot be sucked up at the same time, and while one end is being sucked up, the other end is supported on the transmission line. On the material belt, it is very easy to scratch the belt, which will cause damage to the conveyor belt and affect the normal production process, and even lead to serious consequences of production stoppage.
2. This kind of iron remover does not have explosion-proof function. When it is used underground, once an explosive gas mixture appears, the excitation coil of the magnetic core is very easy to cause an explosion, causing serious consequences.
Due to the above shortcomings, its scope of use is greatly limited and cannot meet people's needs.

Embodiment Construction

[0008] It can be seen from FIG. 1 and FIG. 2 that the present invention includes a yoke plate 1 , lifting lugs 8 installed on the yoke plate 1 , a junction box 7 and a lower supporting plate 12 . Two electromagnetic cores 10 are arranged side by side between the yoke plate 1 and the lower supporting plate 12 , and a certain distance 9 is left between the two magnetic cores 10 . It can greatly widen the magnetic field action area, and the magnetic field lines are tight. The electromagnetic core 10 includes an iron core 2 welded on the lower end of the yoke plate 1 , an exciting coil 3 and an inner supporting plate 4 . The excitation coil 3 is wound on the outside of the iron core 2 according to the best heat dissipation conditions. An annular sealing cylinder 11 surrounded by an outer sealing layer 5 , a lower inner support plate 4 , an upper yoke plate 1 and an inner iron core 2 is provided outside the excitation coil 3 . The upper and lower ends of the sealing layer 5 are r...

Abstract

The present invention relates to an underground explosion-proof strong-magnetic bipolar iron-removing device. It includes magnetic yoke plate, hanger mounted on the magnetic yoke plate, terminal box and lower supporting plate. It is characterized by that between the magnetic yoke plate and lower supporting plate two electromagnetic magnetic cores are parallelly mounted, the excitation coil of magnetic core is isolated from exterior by means of sealing barrel formed from its outer side sealing layer, lower inner supporting plate, magnetic yoke plate and iron core, and its terminal box for excitation coil possess an explosion-proof structure.

Description

1. Technical field [0001] The invention belongs to the technical field of iron removers, and in particular relates to an explosion-proof strong magnetic bipolar iron remover used for removing impurities in raw coal underground. 2. Background technology [0002] With the rapid development of my country's economy, while the demand for coal is increasing, the requirements for coal quality are also increasing. In this way, the screening of coal is becoming more and more common, and the requirements are getting higher and higher. Sorting raw coal underground is the first step in the screening process. Whether impurities in raw coal are removed thoroughly will directly affect the operation of the next process and the protection of machinery and equipment. In particular, the impurities of anchor rods and long pieces mixed in the raw coal will cause great damage to the equipment if they are not removed thoroughly. At present, the sorting equipment used underground is mostly single...
