The further technical scheme of the utility model: be provided with elevator chain between plate and seal cap being located by connecting.
The utility model optimal technical solution: the described plate that is located by connecting is that two semi-circular plate bodys form.
The utility model optimal technical solution: described corrugated tube adopts the glasscloth that is covered with the flame-proof silicon rubber layer to be processed into.
All handwares of the present utility model all can adopt heat-resisting steels to be processed into, and can prevent that it at high temperature is out of shape.
The beneficial effects of the utility model:
1. the utility model can be directly installed on the spray gun at smelting furnace spray gun mouth place, and it is easy for installation, good sealing effect;
2. corrugated tube of the present utility model adopts glasscloth to be processed into coated with abundant flame-proof silicon rubber, and its tensile strength is high, corrosion-resistant, wear resisting property good, has high temperature resistant and fire retardation simultaneously, can be exposed under the hot environment of 380 ℃;
4. between sleeve of the present utility model and seal cap, adopt spring to be connected, can prevent spray gun at work rise and fall rock with tightness system and collide and play cushioning effect.
The accompanying drawing explanation
Fig. 1 is the structural representation after the utility model stretches;
Fig. 2 is that the utility model is put the structural representation be arranged on spray gun after compressing.
In figure: 1-ventpipe, the 2-plate that is located by connecting, 3-elevator chain, 4-corrugated tube, 5-sleeve, 6-spring, 7-seal cap, 8-flue gas chamber, the circular back-up ring of 9-, 10-exhaust gases passes, 11-smelting furnace spray gun, 12-smoke discharge pipe, 13-smelting furnace.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.In Fig. 1, described a kind of top-blown smelting furnace spray gun mouth sealing device comprises that the gun slot with smelting furnace spray gun partly seals the plate 2 that is located by connecting of socket, be used for sealing seal cap 7 and the corrugated tube 4 of spray gun insert port, the upper end of corrugated tube 4 is tightly connected with the plate 2 that is located by connecting, lower end and seal cap 7 are tightly connected, and and the smelting furnace spray gun outer wall between form a flue gas chamber 8, flue gas chamber 8 except with smelting furnace between be communicated with, other position is the sealing shape, the flue gas that the spray gun insert port can be spilt collects, be provided with fume emission interface tube 1 above the plate 2 that is located by connecting, for connecting smoke discharge pipe 12, then flue gas is discharged, be provided with circular back-up ring 9 in the inboard of seal cap 7, be arranged with T-shaped sleeve 5 outside smelting furnace spray gun part in flue gas chamber 8, described T-shaped sleeve 5 is upside down on circular back-up ring 9, the cup dolly of its bottom directly is placed on circular back-up ring, and and smelting furnace spray gun between form exhaust gases passes 10, after tightness system installs, flue gas will directly enter in flue gas chamber 8 from exhaust gases passes 10, and then discharge by smoke discharge pipe 12, between the sidewall of described T-shaped sleeve 5 and seal cap 7, by many springs 6, be connected, play cushioning effect.
