The utility model adopts the mode of double groove welding to be fixed on outside ventilation duct by shell, and form cooling water sandwich with ventilation duct outer wall, during work, tuyere one end is inserted in furnace cupola, air-supply arrangement (as: air blast) blasts air along the tuyere other end, cooling water enters cooling water sandwich from cooling water inlet, form cooling layer at ventilation duct outer wall and be used for cooling, and then flow out from coolant outlet, when reality uses, cooling water flow velocity controls usually at 0.5 ~ 0.75m/s, the temperature of tuyere can effectively control below 1000 DEG C, practical effect is good.
The utility model makes simple, and described ventilation duct and shell are seamless steel pipe and are made, and in actual mechanical process, 20# boiler seamless steel pipe can be adopted to make, and cost of manufacture is low.
For ensureing unimpeded and effective utilization of water circulation, in described cooling water sandwich, be provided with sluice, described sluice in tubular construction and be set in outside ventilation duct.
For better realizing said structure, in the utility model, cooling water sandwich is separated to form the mutually through inner-layer channel of port and outer layer channel by described sluice, port place plane and the ventilation duct entrance place plane of the sluice of corresponding ventilation duct entrance are tangent, are conducive to the cooling effect improving water circulation in cooling water sandwich.
The angle of described tangent port place plane and ventilation duct entrance place plane is 90 ~ 100 °.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model cost of manufacture is low, ventilation duct and shell all can adopt 20# boiler seamless steel pipe to be made, its material uses casting copper, as fine copper or copper alloy, overcome in prior art the shortcomings such as the manufacture difficulty existed when adopting deoxidized cooper water to make tuyere is large, casting flaw soldering difficulty, cost of manufacture are high.
(2) the utility model adopts mode fixed housing and the ventilation duct of double groove welding, and welding rod adopts J427, adopts the mode be connected with screw after split casting compared with existing structure housing with inner casing, and its structure is more firm, and operating process is also simpler.
(3) the utility model effectively raises the cycle efficieny of cooling water by the setting of sluice.
(4) the utility model adopts vertically disposed cooling water inlet and coolant outlet, when overcoming the U-shaped circulates of cooling water in prior art, may cause because steam is on the not smooth impact of water circulation circulation, structure is simple, and design is very reasonable.
