Automatic cleaning device for slip ring chamber carbon powder

Abstract

The invention provides an automatic cleaning device for slip ring chamber carbon powder. A powder blowing device comprises a fan, and an air outlet pipe is communicated with an inner cavity of a slip ring chamber. A powder collecting device comprises a collecting box, an electrostatic adsorption film is fixedly arranged on the outer side of a cylindrical frame, a cleaning soft brush is in movable contact with the electrostatic adsorption film, a plurality of elastic shifting pieces are fixedly arranged on the side, close to the cleaning soft brush, of a sliding plate, and a powder removing channel is formed in the collecting box. The bottom of a second sliding block is fixedly connected with a blocking plate through an extension rod. A powder storage box comprises a main body part and a clamping and embedding rod which are integrally formed, and a weight sensor is in signal connection with a warning indicator. According to the automatic cleaning device for the slip ring chamber carbon powder, the carbon powder can be collected in time, the electrostatic adsorption film can be cleaned in time, secondary pollution is avoided, after a large amount of carbon powder is stored, the powder storage box can be taken down to be cleaned, the powder removing channel can be blocked at the moment, environment pollution is avoided, and the cleaning effect is better.

Description

technical field [0001] The invention relates to the technical field of carbon brush motors, in particular to an automatic cleaning device for carbon powder in a slip ring chamber. Background technique [0002] In the existing alternator, when the unit is running, since the slip ring is always in high-speed rotating motion, and the carbon brush device is a stationary part, the high-speed rotating slip ring is in contact with the carbon brush in the carbon brush device, and the two The friction between them will inevitably produce dust, and the carbon powder produced by friction is not collected at present. Carbon powder enters the generator with the rotation of the unit, which has a great impact on the generator, making the insulation of the slip ring worse against the ground, reducing the insulation of the stator and rotor windings, blocking the core air duct, and causing The rapid temperature rise makes the generator easy to absorb moisture, and the long-term accumulation ...

AI Technical Summary

Problems solved by technology

[0004] However, there are still relatively obvious defects in its use: 1. When the above-mentioned device is in use, the toner in the slip ring chamber is blown to the conical connecting plate, and due to the lack of a corresponding one-way guide structure, the toner It is easy to flow back, and then mix and turbulence with the newly produced toner, and the cleaning effect is poor; 2. After the flame-retardant filter cotton in the above device is used many times, dense toner will be attached to it, thereby reducing its adsorption 3. When the carbon powder accumulates more on the flame-retardant filter cotton of the above-mentioned filter device, it is necessary to replace or clean the filter device. If the filter device is removed without stopping the machine, the toner will be It is continuously blown out, causing pollution to the place of use. However, if it is shut down for processing, it will affect the normal use of the motor where the slip ring chamber is located, and there are many inconveniences.
