Abstract

The utility model provides a slip ring device of a rotary kiln, relates to a structural improvement of the slip ring device, and aims to provide a slip ring device of the rotary kiln, which operates steadily and has high safety. The slip ring device comprises a slip ring and an electric brush, wherein, the electric brush is fixed on the ground through a current collector bracket; and a slip line of the slip ring is fixed on a cylinder body through an insulation bracket. The structural key points of the slip ring device lie in that a U-shaped groove is formed outside the slip line; and the upper surface of a carbon brush of the electric brush is in contact with the U-shaped groove.

Description

A kind of slip-ring device of rotary kiln

Technical field:

The utility model relates to the improvement of slip-ring device structure.

Background technology:

The rotary kiln slip-ring device is the device that is used for the power supplies such as blower fan of rotary kiln.Slip ring and brushgear that traditional slip-ring device is simmered by bare copper wire constitute.Electric current is delivered on the brushgear through cable, is contacted with slip by the carbon brush on the brushgear to be transmitted on the slip ring again, is transmitted on the blower fan by slip ring at last.

The brushgear of traditional slip-ring device is that single-point contacts with slip ring, and often carbon brush takes place the play owing to rotary kiln, slip ring does not contact the phenomenon of cutting off the power supply; In case outage is very big to the production harm of rotary kiln.

Summary of the invention:

The utility model is exactly at the problems referred to above, and a kind of slip-ring device of stable, that fail safe the is good a kind of rotary kiln that turns round is provided.

For achieving the above object, the utility model adopts following technology, the utility model comprises slip ring, brush, brush is fixed on the ground by the current-collector support, the slip of slip ring is fixed on the cylindrical shell by insulating support, its structural feature slip is outside equipped with U-lag, and the carbon brush upper surface of brush contacts with U-lag.

The utility model beneficial effect:

Because the utility model slip is outside equipped with U-lag, the carbon brush upper surface of brush contacts with U-lag, and the carbon brush of brush is contacted with the slip of U-lag all the time; Especially brush is selected the both arms current-collector for use, contact with the slip double-contact, and can rotary kiln axially, radially wobble, guaranteed contacting of slip ring and brush, reaching the effect that running is stablized, fail safe is good.

Description of drawings:

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the A portion enlarged drawing of Fig. 1;

Fig. 4 is the B portion enlarged drawing of Fig. 2;

Fig. 5 is the enlarged drawing of slip with the carbon brush combination.

Embodiment:

As shown in the figure, the utility model comprises slip ring 4, brush 3, and brush 3 is fixed on the ground by current-collector support 7, and the slip 2 of slip ring 4 is fixed on the cylindrical shell 5 by insulating support 1, slip 2 is outside equipped with U-lag 8, and carbon brush 6 upper surfaces of brush 3 contact with U-lag 8.

Brush 3 can be selected the both arms current-collector for use, can purchase from market; The carbon brush 6 of the both sides of both arms current-collector is compressed into slip 2 by the pressure of current-collector spring; Guaranteed the energising effect of brush 3, slip ring 4.
