The utility model is burnt by baking of tundish chews 1, stove formula sealing device 4, and push-pull valve 5, Double-pipe cooler 6 and air-introduced machine 7 form.
Baking of tundish burns chews 1 top that is installed in tundish 2, tundish closed upper part. Stove Formula sealing device 4 is installed in below the middle water containing opening 3, and a stove formula is installed 3 times in each mouth of a river Sealing device 4, several stove formula sealing devices 4 are connected plate by pipeline 8 with push-pull valve 5 Valve 5 is connected with double-pipe cooler 6 by pipeline 9, double-pipe cooler 6 again by pipeline 10 with Air-introduced machine 7 is connected.
Stove formula sealing device 4 is a hollow body of heater 13, body of heater 13 inner lining refractories 11, body of heater 13 has loam cake 12, the mouth of a river 8 communicates with body of heater 13 by the interstitial hole of loam cake 12, shut the bottom of body of heater 13, there is a pipeline 20 side of body of heater 13, seal with active plugboard 14 end of pipeline 20, when observing mouth of a river baking degree, can open plate 14, the bottom of pipeline 20 connects a pipeline 30, is equipped with a butterfly valve 15 that is used for regulating each mouth of a river baking temperature on the pipeline 30, pipeline has a square pipe 16 for 30 times, is used for making pipeline 30 steadily consistent with terrace.
The effect of stove formula sealing device 4 is to guarantee that outside air does not enter wherein when air-introduced machine 7 suction flames, and 3 places cause negative pressure at the mouth of a river, and the flame of tundish 2 is inhaled in the mouth of a river 3, thereby reach the purpose by the lining and the table baking mouth of a river.
Push-pull valve 5 is by tubular type valve body 17, the valve plate 18 that is inserted in the valve body 17 constitutes with the valve rod 19 that is connected with valve plate 18 and be used for controlling the opening degree size of valve plate 18, tubular type valve body 17 1 side valve mouths are connected with the pipeline 8 of being come by stove formula sealing device 4, and the opposite side valve port links to each other with double-pipe cooler 6 by pipeline 9.
The effect of push-pull valve 5 is to regulate mouth of a river baking temperature, by the aperture size of valve rod 19 control valve plates 18, and the exhaust gas volumn of control air-introduced machine 7 suction flames, thus regulate temperature.
Double-pipe cooler 6 mainly is made of two steel pipes that are nested together 22 and 26, steel pipe 22 is enclosed within the centre of steel pipe 26, and steel pipe 22 is used to toast the turnover of flue gas, and cover steel pipe 26 outside holds cooling water, be used for cooling off the baking flue gas, steel pipe 26 upper and lower sides are all with 23,25 sealings of garden cover plate.The two ends up and down of steel pipe 22 have upper flange 21 and lower flange 31, the pipeline of being come by push-pull valve 5 places connects by upper flange 21, the pipeline 10 that connects on the lower flange 30 is connected with air-introduced machine 7, a blast pipe 29 that is used for discharged air is arranged on garden, the top cover plate 23 of steel pipe 26, steel pipe 26 1 side lower parts have a hand hole 28, as cooling water inlet, a drainpipe 24 is arranged at its opposite side top, has a blow-off pipe 27 on the following garden cover plate 25 of steel pipe 26.With the dirt in the rice discharging cooling water.
The effect of double-pipe cooler 6 is flue-gas temperatures that control enters air-introduced machine 7.3 flue-gas temperatures of coming out reach 800 ℃ from the mouth of a river, and the operating temperature of air-introduced machine 7 requires to be lower than 250 ℃, when flue gas is entered by the pipeline that upper flange 21 connects, when the row of conduits that is connected by lower flange 30 is come out again, lower the temperature by the water quench in the steel pipe 26 of steel pipe 22 overcoats, by the water yield of regulating double-pipe cooler 6 flue-gas temperature is dropped to below 250 ℃, enter air-introduced machine 7 by pipeline 10 then, by outlet 32 flue gas be discharged again.
For guaranteeing air-introduced machine 7 security of operation, on air-introduced machine 7 entrance pipes, adorn an electric contact bimetallic thermometer, in case supply water to occur undesired, during cigarette temperature superelevation, the air-introduced machine tripping operation of can reporting to the police automatically.
