[0002] The burner is a device used to burn through the furnace eye during the smelting process of the submerged arc furnace. It uses the conductive and clamping parts of the burner to conduct the high voltage electricity of the submerged arc furnace to the graphite electrode. The graphite electrode forms a pressure difference with the carbon refractory material on the inner side of the furnace wall of the submerged arc furnace, which produces an arc phenomenon, thereby burning through all the refractory materials of the furnace wall of the submerged arc furnace and opening the furnace eye. During the operation of the traditional submerged arc furnace burner, the burner handle needs to be manually held to push the burner gun body. During this process, the staff needs to withstand high temperature radiation, the working environment is harsh, and the labor intensity is high.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] like Figure 1 The burner feeding device shown comprises a fixing seat 1, a motor 2, a first connecting rod 3, a second connecting rod 4, a third connecting rod 5 and a fixed hanging ring 6. The burner 7 is movably sleeved in the hanging ring 6. In order to ensure the horizontality of the burner 7, the number of the hanging rings 6 is at least two.

[0019] In this embodiment, the first connecting rod 3, the second connecting rod 4, and the third connecting rod 5 are arranged in the same vertical plane A; the motor 2 is arranged between the horizontal plane where the burn-through device 7 is located and the horizontal plane where the fixing seat 1 is located, and the output shaft of the motor 2 is perpendicular to the vertical plane A.

[0020] Furthermore, a slide groove 3.1 is provided on the rod body of the first connecting rod 3, and one end of the first connecting rod 3 is hinged to the fixing seat 1; one end of the second connecting rod 4 is connected to the output shaft of the motor 2, and the other end of the second connecting rod 4 is movably arranged in the slide groove 3.1; when the output shaft of the motor 2 drives one end of the second connecting rod 4 to rotate, the other end of the second connecting rod 4 can slide in the slide groove 3.1; one end of the third connecting rod 5 is hinged to the side wall of the burn-through device 7, and the other end of the third connecting rod 5 is hinged to the other end of the first connecting rod 3.
