Further, aforesaid converter evaporation cooling air flue, wherein: the chamber width of annular water tank inner chamber is not less than 40mm.
The utility model has the advantages that: because the assemblage gap between mouth fixed section flue and interlude flue is excessive, so expanding with heat and contract with cold for compensating flue and reserve flue and expand with heat and contract with cold after with gap, annular water tank is utilized to block the residual gap in assemblage gap, red-hot so red slag to expand with heat and contract with cold slagging scorification in the chamber that to enter with gap and surrounded by mouth fixed section flue, interlude flue, sealing Extensible connection device with regard to not easily passing through the less flue of spacing, substantially reduce the scarfing cinder difficulty of converter evaporation cooling air flue, and then improve production efficiency; And operationally, by passing into water coolant to cool in annular water tank, thus improve the work-ing life of annular water tank.
Accompanying drawing explanation
Fig. 1 is the structural representation of converter evaporation cooling air flue described in the utility model.
Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1.
Fig. 3 is the structural representation of annular water tank shown in Fig. 2.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
Converter evaporation cooling air flue, as Fig. 1, Fig. 2, shown in Fig. 3, comprise the movable gas hood 1 be positioned at above converter mouth, movable gas hood 1 top is connected with mouth fixed section flue 2 bottom, mouth fixed section flue 2 top is connected by sealing Extensible connection device 6 with interlude flue 3 bottom, sealing Extensible connection device 6 can be telescopic joint, interlude flue 3 top is connected with end flue 4, assemblage gap is there is between mouth fixed section flue 2 and interlude flue 3, annular water tank 5 is provided with in assemblage gap, in actual applications, annular water tank 5 can be fixed by the flange on support and mouth fixed section flue 2 or interlude flue 3, annular water tank 5 is provided with water inlet pipe 51 and rising pipe 52, and leave to expand with heat and contract with cold between annular water tank 5 and mouth fixed section flue 2 or interlude flue 3 and use gap.Water coolant enters annular water tank 5 from water inlet pipe 51, and then flows out from rising pipe 52, and such water coolant just can cool annular water tank 5, extends the work-ing life of annular water tank 5.
In the present embodiment, two pieces of dividing plates 53 are provided with in the inner chamber of annular water tank 5, and two pieces of dividing plates 53 are positioned on the same diameter line of annular water tank 5, two pieces of dividing plates 53 intercept the inner chamber of annular water tank 5 as first, second not connected separate chamber 541,542, the two ends of first, second separate chamber 541,542 are all respectively arranged with a water inlet pipe 51 and a rising pipe 52, and in first, second separate chamber 541,542 water coolant flow to identical, if do not arrange dividing plate 53 and only arrange a water inlet pipe and a rising pipe on annular water tank 5, the easily annularly flow and form whirlpool in the inner chamber of annular water tank 5 of such water coolant, the water coolant heated up is caused not discharge in time, thus affect the cooling performance of annular water tank 5, the present embodiment forms annularly flow in order to prevent water coolant in annular water tank 5 inner chamber, so annular water tank 5 inner chamber is intercepted into two separate chamber, and two separate chamber are all respectively arranged with a water inlet pipe and a rising pipe, such water coolant just can pass through annular water tank 5 fast, thus raising cooling performance, in addition, two pieces of dividing plates 53 are positioned on the same diameter line of annular water tank 5, can first be made like this, second separate chamber 541, 542 shapes are identical, thus make water coolant to first, second separate chamber 541, the cooling performance of 542 is identical, annular water tank 5 is avoided to produce distortion because two separate chamber cooling performances are different, in the present embodiment, the cross-sectional shape of annular water tank 5 inner chamber is rectangle, and the chamber width of annular water tank 5 inner chamber is not less than 40mm, the cross-sectional shape of annular water tank 5 inner chamber is set as that rectangle can make annular water tank 5 better for blocking, the height of annular water tank 5 can according to the assemblage gap between mouth fixed section flue 2 and interlude flue 3, and need the flue reserved expand with heat and contract with cold with gap and determine, the altitude range of usual annular water tank 5 is between 120 ~ 160mm, in the present embodiment, limiting the chamber width of annular water tank 5 inner chamber is cooling performance in order to ensure annular water tank 5, prevent from causing not having abundant water coolant to cool annular water tank 5 because chamber width is too small.In addition, after annular water tank 5 installs in assemblage gap, the mounting height of the water inlet pipe 51 on annular water tank 5 is lower than the mounting height of rising pipe 52, arrange like this and water coolant can be made to flow out from eminence from the lower inflow annular water tank 5 again, water coolant in annular water tank 5 can produce water vapour because of high temperature, the such flow direction of water coolant has complied with the ascension direction of water vapour in annular water tank 5, and water vapour can be made like this to discharge from annular water tank 5 very smoothly.
The beneficial effects of the utility model are: because the assemblage gap between mouth fixed section flue and interlude flue is excessive, so expanding with heat and contract with cold for compensating flue and reserve flue and expand with heat and contract with cold after with gap, annular water tank is utilized to block the residual gap in assemblage gap, red-hot so red slag to expand with heat and contract with cold slagging scorification in the chamber that to enter with gap and surrounded by mouth fixed section flue, interlude flue, sealing Extensible connection device with regard to not easily passing through the less flue of spacing, substantially reduce the scarfing cinder difficulty of converter evaporation cooling air flue, and then improve production efficiency; And operationally, by passing into water coolant to cool in annular water tank, thus improve the work-ing life of annular water tank.
