Automatic material distributing device for semi-closed submerged arc furnace

Abstract

The invention relates to the technical field of submerged arc furnace application, and discloses an automatic material distributing device for a semi-closed submerged arc furnace. The automatic material distributing device comprises a stock bin, a material pipe, a feeder, a chute rotating mechanism, a chute tilting mechanism and a chute, wherein the stock bin communicates with the feeder through the material pipe; the feeder communicates with the chute through a throat pipe; the chute rotating mechanism is connected with the upper end side of the chute to drive the chute to rotate horizontally; the chute tilting mechanism is connected with the upper end side of the chute to drive the chute to tilt vertically; a swivel joint is arranged on the outer side of the upper end of the chute; and asmoke sealing mechanism is arranged at the joint position of the throat pipe and the chute. By controlling the rotation angle and tilting degree, the positioning is accurate, and the automatic control is convenient to realize, so that the automatic feeding of the semi-closed submerged arc furnace is realized, the labor force is released, the production labor costs are reduced, the automatic operation of equipment is improved, and the requirements of economic indexes of an electric furnace are met.

Description

technical field [0001] The invention relates to the technical field of submerged arc furnace application, in particular to an automatic material distribution device for a semi-closed submerged arc furnace. Background technique [0002] During the production process of semi-closed submerged arc furnace for smelting various alloys, a large amount of scorching furnace gas will be generated in the furnace, and the energy of scorching furnace gas will be fully utilized to create high-temperature chemical reaction conditions for various raw ores, while maintaining good gas permeability of the furnace charge , in order to accelerate the smooth progress of the chemical reaction in the furnace. When the air permeability in the submerged arc furnace is good, it can not only make full use of the heat energy of the high-temperature furnace gas to preheat the charge and reduce the volatilization loss of the main raw materials, but also help to reduce the temperature gradient in the furna...
