Abstract
The utility model relates to an arc furnace scrap preheater used for smelting metal materials. At present, a plurality of kinds of arc furnace scrap preheaters oversea all have a problem that when steel scraps are added, flue gas overflows, and peripheral environment of equipment is seriously polluted by the flue gas. The arc furnace scrap preheater comprises a vertical shaft, a shutter mechanism, a trough, a steel pushing device, a pushing box, a top cover and a horizontal moving mechanism. The vertical shaft is divided into an upper vertical shaft and a lower vertical shaft through the shutter mechanism arranged in a cavity, the trough is arranged on the bottom of the lower vertical shaft and provided with the steel pushing device and the pushing box, and one end of the trough is communicated with a side furnace opening of the arc furnace. The top cover is arranged on the top of the vertical shaft, and the lower end of the trough is provided with the horizontal moving mechanism. The arc furnace scrap preheater preheats steel scrap materials through high temperature flue gas produced when the arc furnace is smelted, thereby achieving an effect of saving energy. The shutter mechanism is arranged to avoid overflow of the high temperature flue gas and escape of flue gas caused by falling of the steel scraps when the steel scraps are added, so that operation environment is protected.
Description
Technical field
The utility model relates to the electric arc furnaces scrap preheater of smelting metal material.
Background technology
At present, external several electric arc furnaces scrap preheaters, as the continous way scrap preheater of Italian Dexing company, the shaft furnace of German Fox company etc. when adding steel scrap, all exist certain flue gas excessive, and the equipment peripheral environment is by problems such as flue gas severe contaminations.
The utility model content
The technical problem that the utility model solved provides a kind of smoke pre-heating steel scrap that electric arc furnaces can be discharged, again the steel scrap after the preheating is added melting in the stove, simultaneously when steel scrap adds preheating device, no flue gas leaks and pollutes operating environment around the stove, reaches the environment-friendly type scrap preheater of good environmental protection and energy saving effect.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
A kind of environment-friendly type scrap preheater, it is characterized in that: comprise vertical shaft, guillotine mechanism, hopper, pusher, push away case, top cover, horizontal mobile mechanism, vertical shaft is divided into vertical shaft, following vertical shaft by the guillotine mechanism that is arranged on inner chamber, the bottom of following vertical shaft is provided with hopper, pusher is set on the hopper, pushes away case, hopper one end is communicated with the wing furnace mouth of electric arc furnaces; Described vertical shaft top is provided with top cover, and the lower end of hopper is provided with horizontal mobile mechanism.
The side of above-mentioned following vertical shaft is provided with exhaust outlet.
Above-mentioned guillotine mechanism comprises hydraulic cylinder, flashboard body, is arranged on the driving wheel that has spring of flashboard body bottom, the flashboard body is the rectangular structure of hollow, one end of flashboard body is connected with hydraulic cylinder, the driving wheel of flashboard body bottom is arranged on the track on the vertical shaft intracavity sidewall, and the front end on plane is provided with several fore paws on the flashboard body.
Compared with prior art; the high-temperature flue gas that produces in the stove when the utility model utilizes electric arc furnace smelting is realized the preheating to raw scrap material, has reached the effect of energy savings, when guillotine mechanism being set preventing to add steel scrap; the flue gas that the excessive and steel scrap of furnace high-temperature dust flue gas falls to the bringing impact that leaks; the protection operating environment, compact conformation, easy maintenance; the automatic controlling level height; operation is reliable, and manufacturing cost is relatively low, is easy to realize.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of guillotine mechanism of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1,2, the utility model comprises vertical shaft, guillotine mechanism 1, hopper 6, pusher 8, pushes away case 5, top cover 3, horizontal mobile mechanism 9, vertical shaft is divided into vertical shaft 2, following vertical shaft 4 by the guillotine mechanism 1 that is arranged on inner chamber, the bottom of following vertical shaft 4 is provided with hopper 6, pusher 8 is set on the hopper 6, pushes away case 5, hopper 6 one ends are communicated with the wing furnace mouth of electric arc furnaces 7; Described vertical shaft top is provided with top cover 3, and the lower end of hopper 6 is provided with horizontal mobile mechanism 9.
Above-mentioned guillotine mechanism 1 comprises hydraulic cylinder 11, flashboard body 10, is arranged on the driving wheel that has spring 12 of flashboard body 1 bottom, flashboard body 1 is the rectangular structure of hollow, one end of flashboard body 10 is connected with hydraulic cylinder 11, the driving wheel 12 of flashboard body 10 bottoms is arranged on the track 13 on the vertical shaft intracavity sidewall
The front end on plane is provided with several fore paws 14 on the flashboard body 10.
Guillotine mechanism 1 is divided into vertical shaft 2 and following vertical shaft 4 with vertical shaft, and flashboard machine 1 is driven by hydraulic cylinder 11, and the last plane of flashboard can be born steel scrap and be added fashionable impact, and lower plane can bear the baking of high-temperature flue gas.The front end on plane has several special pawls so that lock is when back and forth opening and closing on the flashboard, can will go up in the vertical shaft 2 and draw back around the steel scrap that connects together mutually, and allow it fall into down in the vertical shaft 4, guillotine mechanism has the driving wheel 12 of four groups of band springs, wheel moves on the track 13 of last vertical shaft 2 sidewalls, and groups of springs makes flashboard can slow down steel scrap to add fashionable impact.
When in vertical shaft, adding steel scrap, earlier the guillotine mechanism between the upper and lower vertical shaft 1 is closed, isolate the hot flue gas of vertical shaft 4 down, open top cover 3, open the steel scrap basket that winches to the upper end, steel scrap is added go up in the vertical shaft 2, hang the material basket, close top cover 3.After steel scrap in the last vertical shaft 2 falls into down vertical shaft 4 fully, close guillotine mechanism 1, last vertical shaft 2 adds steel scrap once more, beginning new round steel scrap warm-up cycle.
According to the working of a furnace, the guillotine mechanism between the upper and lower vertical shaft 1 to be opened gradually, the steel scrap in the last vertical shaft 2 is fallen down in the vertical shaft 4, and the steel scrap amount of whereabouts is controlled by size and the speed that guillotine mechanism 1 is opened, and effectively reduces blanking impact and steel scrap and twines.
Steel scrap in the hopper 6 of following vertical shaft 4 by the high-temperature flue gas preheating, by the interior pusher 8 of hopper 6, push away case 5 steel scrap is steadily pushed in the electric arc furnaces 7 by certain speed.
After the preheating scrap, the warp exhaust outlet of vertical shaft side down enters the dust pelletizing system pipeline to the high-temperature flue gas of discharging in the burner hearth in following vertical shaft 4.
