Furnace ramming mechanism of furnace ramming vehicle for large-capacity submerged arc furnace

Abstract

The invention discloses a furnace ramming mechanism of a furnace ramming vehicle for a large-capacity submerged arc furnace. The ramming mechanism comprises a protection mechanism, a scraping mechanism, an inner cylinder body and an outer cylinder body; a limiting plate is arranged outside the inner cylinder body; a shell is arranged on one side of the outside the inner cylinder body, the shell isfixedly connected with the inner cylinder body through a fixing plate, a first driving shaft is vertically fixed inside the shell, and the top end of the first driving shaft penetrates through the outer wall of the inner cylinder body and extends into the inner cylinder body. The protection mechanism is arranged on one side of a hopper, connecting seats are fixed on the opposite sides of a high-temperature-resistant ceramic protection plate and the hopper in the protection mechanism, a plurality of damping springs are fixed between the connecting seats, and the damping springs are arranged atequal intervals between the connecting seats, so that the protective effect is improved; during furnace ramming, the high-temperature-resistant ceramic protection plate plays a role in protecting, ametal conductor is prevented from causing danger by being directly collided with a large sleeve, brasses and electrodes in the furnace, and the damping springs play a certain role in buffering.

Description

technical field [0001] The invention relates to the technical field of a furnace stamping car, in particular to a furnace stamping mechanism of a furnace stamping car for a large-capacity submerged arc furnace. Background technique [0002] The large-capacity submerged arc furnace is a kind of equipment used to produce alloys. When the submerged arc furnace is used, it needs to be equipped with a furnace stamping machine. The furnace stamping machine is an open and semi-closed submerged arc furnace used to produce silicon-based ferroalloys. The special mechanical equipment for feeding and pounding materials at the furnace mouth of the reduction electric furnace is used to make the material distribution in the furnace uniform, expand the reaction area, eliminate suspended materials, crush slag, reduce crusts and flames on the material surface, and achieve smooth furnace conditions. It can also be applied to the same type of electric furnace to produce other ferroalloys and ca...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a large-capacity submerged arc furnace with a pounding car pounding mechanism, to solve the poor functionality proposed in the above background technology, unable to collect materials, distribute materials, eliminate suspended materials, smash slag, and reduce knots. The shell and the surface of the material have the function of spraying fire, and the above functions need to be replaced to fully realize the above functions. There is no protective mechanism. When the top of the mechanism collides with the large sleeve, copper tiles, and electrodes in the furnace, safety accidents are likely to occur and the material cannot be distributed in time when feeding. It is easy to cause slag crusting and low combustion efficiency
