[0002] In copper smelting, the converter is an important piece of equipment for smelting matte produced by flash furnace into crude copper needed for the anode furnace. Among them, the residual anode feeding system is the key feeding and transportation equipment in converter production.

[0003] Currently, existing converter-based anode addition processes have been found to have at least the following technical problems during production;

[0004] If the converter feeding system (converter feeding mechanism) malfunctions during the converter feeding process, the converter feeding mechanism cannot be added to the furnace in time for blowing. This can result in minor issues such as the need to lift the converter feeding mechanism by overhead crane and directly feed it into the furnace, or major production accidents such as affecting the converter blowing cycle. Therefore, improving the working efficiency of the converter feeding mechanism and reducing its failure rate and operating costs have become pressing issues to be addressed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel roller device for a converter residual electrode feeding mechanism, which solves the problems of poor stability and easy failure of existing converter feeding mechanisms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Preferably, a slot is provided at one end of the load-bearing shaft near the card plate, and the slot is adapted to the card plate.

[0010] Preferably, the card plate is fixed to the surface of the roller bracket by two hexagon socket head cap screws. The surface of the roller bracket has two threaded holes that are compatible with the hexagon socket head cap screws, and the card plate has two through holes that are fitted with the hexagon socket head cap screws.

[0011] Preferably, the inner ring of the rolling bearing is fixedly connected to the load-bearing shaft, the outer ring of the rolling bearing is fixedly connected to the wheel, and the two rolling bearings are located inside the two mounting grooves formed between the two elastic retaining rings and the second bushing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] I. The roller device mainly includes a wheel, a roller bracket, a load-bearing shaft, a clamping plate, a first bushing, a second bushing, an elastic retaining ring, rolling bearings, and an L-shaped through hole. The wheel is mounted on the load-bearing shaft via rolling bearings and contacts the guide rail of the converter feeding mechanism, bearing the weight of the feeding mechanism and the entire roller device. The load-bearing shaft is positioned via positioning holes on the roller bracket, providing axial positioning for the roller device and bearing axial and radial forces from the roller bracket. The clamping plate is fixed to the roller bracket using hexagonal socket head cap screws. The first bushing, the second bushing, and the elastic retaining ring provide axial positioning for the rolling bearings and rollers. The rolling bearings of the roller device are lubricated via grease fittings during operation, allowing simultaneous lubrication of two rolling bearings, facilitating maintenance of the rolling bearings in this application. The lubricating oil remaining in the L-shaped through hole continuously flows to the two rolling bearings during operation of the roller device, preventing rolling bearing failure and giving this application high stability, thereby reducing the failure rate of the converter feeding mechanism.
