Description

Technical Field

[0001] The utility model belongs to the technical field of an electromagnetic iron remover control box, in particular to a mine-used explosion-proof electromagnetic iron remover control box. Background Art

[0002] Electromagnetic iron remover is a device that uses electromagnetic force to remove ferromagnetic materials from objects. Its working principle is to generate a magnetic field by energizing the electromagnetic coil, so that the ferromagnetic body becomes a temporary magnet under the action of the magnetic field, is attracted to the position of the coil, and adheres to the iron remover. Once a certain level is reached, the magnetism can be weakened or offset by turning off the current or the reverse polarity magnetic field, thereby releasing the ferromagnetic material. Among them, the explosion-proof electromagnetic iron remover control box is a device specially designed for the explosion-proof electromagnetic iron remover for mining. It is mainly used in coal mines, in AC 50Hz, voltage up to 1140V lines, to transform and rectify the explosion-proof electromagnetic iron remover to provide excitation power, and to directly start and stop the motor used in the iron unloading mechanism. At the same time, it can also protect the iron remover, motor and related circuits.

[0004] Although the above utility model can extinguish fires when short circuits and heating occur in the box, and dissipate heat from the operation of equipment in the box, the dust concentration in the air is often very high in the mining environment, and the fan is prone to accumulate dust, which reduces the heat dissipation effect of the fan. In addition, dust will directly enter the heat dissipation port, blocking the heat dissipation port and affecting the effective heat dissipation. At the same time, as the heat dissipation efficiency decreases, the temperature inside the control box will gradually increase. Excessive temperature will not only affect the normal operation of the electromagnetic iron remover, but may also damage the internal electronic components and shorten the service life of the equipment.
