Embodiment 1

[0048] as attached figure 1 to attach image 3 As shown, an embodiment of a metal dust treatment device, the metal dust treatment device 10 specifically includes:

[0049] The adsorption module 1 encapsulates the electromagnet 21, the power supply 22, the magnetizing switch 3 and the demagnetizing switch 4 as one;

[0050] The power supply 22 provides the electric energy needed for the electromagnet 21 to work;

[0051] The magnetizing switch 3 is used to connect the forward magnetizing circuit of the power supply 22 and the electromagnet 21;

[0052] The demagnetization switch 4 is used to connect the reverse demagnetization circuit of the power supply 22 and the electromagnet 21, and change the current direction of the electromagnet 21;

[0053] And it is located at the installation bottom of the adsorption module 1, and is used to fix the adsorption module 1 to the mounting seat 2 on the side of the wheelset 6 (the wheelset 6 is made of carbon steel, which is an excellen...

Embodiment 2

[0059] Another embodiment of the metal dust treatment device, the metal dust treatment device 10 specifically includes:

[0060] The adsorption module 1 encapsulates the electromagnet 21, the power supply 22, the magnetizing switch 3 and the demagnetizing switch 4 as one;

[0061] The power supply 22 provides the electric energy needed for the electromagnet 21 to work;

[0062] The magnetizing switch 3 is used to connect the forward magnetizing circuit of the power supply 22 and the electromagnet 21;

[0063] The demagnetization switch 4 is used to connect the reverse demagnetization circuit of the power supply 22 and the electromagnet 21, and change the current direction of the electromagnet 21;

[0064] And the mounting base 2 located at the installation bottom of the adsorption module 1 for fixing the adsorption module 1 on the fender 7 of the wheel set 6 .

[0065] as attached Figure 5 As shown, different from Embodiment 1, in this embodiment, a fender 7 is respectivel...

Embodiment 3

[0068] as attached Figure 6 As shown, on the basis of Embodiments 1 and 2, the metal dust treatment device 10 further includes a package packaged in the adsorption module 1 and connected in series with the electromagnet 21 for adjusting the forward magnetization current or reverse demagnetization of the electromagnet 21. Current adjustable resistor VR. By increasing the adjustable resistance VR, it is very convenient to control the magnitude of the forward magnetizing current or the reverse demagnetizing current, neither will cause abnormality of the wheel set 6 due to the excessive electromagnetic force causing other metal substances made of steel to be absorbed. cause a fault, and will not cause even the worn metal powder to be unable to be adsorbed to the end face of the wheel set 6 or the fender 7 because the electromagnetic force is too small. The metal dust treatment device 10 further includes an indicator light 5 packaged in the adsorption module 1 and connected in se...

Abstract

The invention provides a metal dust treatment device and method. The device comprises: an adsorption module which packages an electromagnet, a power supply, a magnetizing switch and a demagnetizing switch as one body; the power supply provides the electric energy needed for the electromagnet to work; the magnetizing switch is used for connecting the power supply and the forward magnetizing circuitof the electromagnet. The demagnetization switch is used for turning on the power supply and the reverse demagnetization loop of the electromagnet; and a mount for mounting the suction module on theside or fender of the wheelset of the train. By applying the invention, the technical problems of serious metal dust intrusion at the bottom of the rail transit train, greatly shortened service life of the electric box, increased maintenance frequency and huge cleaning workload can be solved.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a metal dust treatment device and method for rail transit vehicles. Background technique [0002] At present, rail transit technology has been widely used at home and abroad. Judging from the current operating environment of train bottoms in various domestic depots, metal dust pollution caused by friction between wheelsets and rails is very serious. Metal dust pollution has a great impact on electrical boxes such as train traction inverters, auxiliary converters, and filter reactors. At the present stage, there is a large amount of metal powder in the train operating environment of all railway depots across the country, and the electric box at the bottom of the train has serious dust intrusion even under a higher protection level. The same is true for domestically imported foreign vehicles. Metal dust pollution greatly shortens the service life of the electrical ...
