Below with reference to the accompanying drawings the split type bonnet 1 of the rotatable metallurgical furnace according to the embodiment of the present invention is described.
As depicted in figs. 1 and 2, the first cover body 100, second cover body 200 and baffle plate 400 is comprised according to the split type bonnet 1 of the rotatable metallurgical furnace of the embodiment of the present invention.
First cover body 100 is straight tube shape and the lower surface of the first cover body 100 is arc, and the upper end of the first cover body 100 is provided with main outlet flue 110 (shown in above-below direction arrow A as in Figure 1 and Figure 2).Second cover body 200 is arc, and the upper end of the second cover body 200 is connected with the sidewall of the lower end of the first cover body 100, and the lower surface of the lower edge of the second cover body 200 and the first cover body 100 is circumferentially same, and the second cover body 200 is provided with emergent outlet flue 210.Baffle plate 400 is located at the junction of the first cover body 100 and the second cover body 200, and the upper end of baffle plate 400 is connected swingably with the first cover body 100 or the second cover body 200.
According to the split type bonnet 1 of the rotatable metallurgical furnace of the embodiment of the present invention, by the second cover body 200 is arranged to arc, and arc is arranged in the lower surface of the first cover body 100, make the lower surface of the lower edge of the second cover body 200 and the first cover body 100 circumferentially same, thus make the shape adaptation of split type bonnet 1 bottom of rotatable metallurgical furnace in the movement locus of body of heater upper end, the volume of the split type bonnet 1 of rotatable metallurgical furnace significantly can be reduced like this when ensureing the collecting effect to high-temperature flue gas, the space that split type bonnet 1 entirety reducing rotatable metallurgical furnace takies, and the first cover body 100 not easily dust stratification of arc, good airproof performance.In addition, by arranging emergent outlet flue 210 on the second cover body 200, and swingable baffle plate 400 is set in the junction of the first cover body 100 and the second cover body 200, baffle plate 400 relies on self gravity sag, flue gas is divided and is interposed between baffle plate 400 both sides, technique can be facilitated like this to overhaul and adjustment, and when the slagging scorification of body of heater fire door is serious, can by push-jump for baffle plate 400 past after baffle plate 400 is encountered in body of heater slagging scorification in the process of rotation, make body of heater normal rotation, namely ensure that the setting of baffle plate 400 does not affect the rotation of body of heater.Therefore, according to the split type bonnet 1 of the rotatable metallurgical furnace of the embodiment of the present invention have volume little, take up room little, not easily dust stratification, good airproof performance, be convenient to technique maintenance and the advantage such as adjustment.
Below with reference to the accompanying drawings the split type bonnet 1 of the rotatable metallurgical furnace according to the specific embodiment of the invention is described.
In specific embodiments more of the present invention, as depicted in figs. 1 and 2, the first cover body 100, second cover body 200 and baffle plate 400 is comprised according to the split type bonnet 1 of the rotatable metallurgical furnace of the embodiment of the present invention.Wherein, the upper end of baffle plate 400 can adopt ring-type earrings to hang on the second cover body 200.
Particularly, as shown in Figure 1, emergent outlet flue 210 is located at the middle part of the second cover body 200 along the vertical direction, on the one hand can convenient operation, on the other hand can so that the discharge of flue gas.
Further, as shown in Figure 1, the sidewall of the lower end of the first cover body 100 is provided with upper end that arc connects pipeline section 120, first cover body 100 is connected pipeline section 120 with arc connected.The first cover body 100 can be made thus to be connected more level and smooth with the second cover body 200, and structure more rationally and better tightness.
Alternatively, the first cover body 100, second cover body 200 and baffle plate 400 can be made up of alloy-steel plate, reach radiating effect by superficial air flowing.At least one in first cover body 100, second cover body 200 and baffle plate 400 also can be made up of membrane wall, the water circulation of whole metallurgical furnace is participated in by the cooling water in membrane wall, utilize the cooling water through membrane wall to reduce flue-gas temperature, and membrane wall directly can produce water vapour thus improve cooling effectiveness.In addition, adopt membrane wall to also help the operating pressure improving recirculated water, thus membrane wall operating temperature is improved, when avoiding cooling, smoke components condenses and adds heavy corrosion, can extend the service life of the bonnet of rotatable metallurgical furnace thus.
In specific embodiments more of the present invention, as depicted in figs. 1 and 2, the first cover body 100 is connected by expansion joint 300 with the second cover body 200.
Expansion joint 300 comprises the first connecting plate 310, second connecting plate 320, flexible link belt 330 and airtight and watertight padding 340.
First connecting plate 310 is fixed on the first cover body 100.Second connecting plate 320 is fixed on the second cover body 200.One end of flexible link belt 330 is connected with the first connecting plate 310 by screw bolt and nut, and the second end of flexible link belt 330 is connected with the second connecting plate 320 by screw bolt and nut.Flexible link belt 330, first connecting plate 310, second connecting plate 320, first cover body 100 and the second cover body 200 limit the annular seal space above the junction being positioned at the first cover body 100 and the second cover body 200, are filled with airtight and watertight padding 340 in described annular seal space.The gap of expansion joint 300 excellent sealing first cover body 100 and the second cover body 200 junction can be made thus, and do not affect the relative motion of the first cover body 100 and the second cover body 200.
Further, as shown in Figure 2, dividing plate 350 is provided with in described annular seal space, dividing plate 350 is connected with the first connecting plate 310 or the second connecting plate 320, dividing plate 350 is provided with steel wire 360, and airtight and watertight padding 340 comprises the lower filler portion 342 be positioned at below dividing plate 350 and the upper filler portion 341 be positioned at above dividing plate 350.So not only can ensure the stability of airtight and watertight padding 340 in described annular seal space, to ensure the sealing effectiveness of airtight and watertight padding 340 to gap between the first cover body 100 and the second cover body 200, and when can ensure that relative motion occurs for the first cover body 100 and the second cover body 200, airtight and watertight padding 340 still can play good sealing effectiveness.
