Abstract
The utility model provides the technical scheme of a reversed conical degree oxygen gun. The proposal comprises a spray head, a gun body and a supporting rack, wherein a water inlet pipe and a water outlet pipe are arranged on the gun body; a reversed conical degree gun body is arranged under the gun body; the gun body and the reversed conical degree gun body are provided with coaxial outer pipes, coaxial middle pipes and coaxial inner pipes. The utility model has the proposal that the middle pipes and the outer pipes of the reversed conical degree gun body part have identical conical degree, so that the distance between each middle pipe and each outer pipe of the gun body and the reversed conical degree gun body is identical. The structure causes the distance between the coaxial outer pipes and the coaxial middle pipes to be identical, so that cooling water can not generate the change of flow rate when flowing among the outer pipes and the middle pipes in the identical distance. Thus, the cooling effect on the outer pipes is identical, so that the problem that the cooling effect of part of sections is weakened can not be caused.
Description
Affiliated technical field:
The utility model relates to steel-making equipment in the Iron And Steel Industry, especially a kind of top-blown oxygen converter back draught oxygen rifle.
Background technology:
In the prior art, the oxygen rifle that top-blown oxygen converter is used is in converting process, the oxygen rifle is in the emulsion of steel, slag gas, owing to returning reasons such as dried and splash, easy steel bonding in its underpart and dry slag move for some time and will handle steel bonding and dry slag, otherwise will can not carry oxygen rifle hole when steel bonding is serious, be forced to burning torch, this has just shortened the work-ing life of oxygen rifle, and has interrupted rhythm of production.In order to solve the problem of steel bonding of oxygen rifle and dry slag, people have developed back draught oxygen rifle, and dry slag is come off automatically, and steel bonding also is easy to handle, and greatly reduces working strength of workers.Because the rifle body of back draught oxygen rifle has tapering, there is variation in the internal diameter of rifle body, therefore, the water coolant flow velocity of cooling oxygen rifle, change at rifle body portion section, the problem that causes part section rifle body cooling performance to weaken, this is an existing in prior technology subject matter.
Summary of the invention:
The utility model is exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of back draught oxygen rifle, this scheme adopts the middle pipe in back draught rifle body portion to have identical tapering with outer tube, this just can make the backwater flow velocity of oxygen gun cooling water not have big variation, thereby has guaranteed the whole cooling performance of oxygen rifle.
This programme is realized by following technical measures: include shower nozzle, rifle body and support, on the top of rifle body water inlet pipe and rising pipe are arranged, the bottom of rifle body is a back draught rifle body, described rifle body and back draught rifle body have co-axial outer tube, middle pipe and interior pipe, and the characteristics of this programme are that the middle pipe in back draught rifle body portion has identical tapering with outer tube.
The beneficial effect of this programme can learn according to the narration to such scheme, because in this scheme, has identical tapering at the middle pipe of back draught rifle body portion with outer tube.This structure just makes the spacing between co-axial outer tube and the middle pipe identical, and water coolant flows between identical outer tube of spacing and middle pipe, the variation of flow velocity just can not appear, therefore, also just identical to the cooling performance of outer tube, the problem that can not cause part section cooling performance to weaken.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure synoptic diagram of the utility model embodiment.
1 is shower nozzle among the figure, and 2 is back draught rifle body, and 3 is the rifle body, and 4 is support, and 5 is water inlet pipe, and 6 is rising pipe, and 7 is outer tube, and 8 is middle pipe, and 9 is interior pipe.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, the back draught oxygen rifle of this programme, shower nozzle (1) is arranged, rifle body (3) and support (4), water inlet pipe (5) and rising pipe (6) are arranged on the top of rifle body (3), the bottom of rifle body (3) is a back draught rifle body (2), described rifle body (3) and back draught rifle body (2) have co-axial outer tube (7), middle pipe (8) and interior pipe (9), this programme is to have identical tapering at back draught rifle body (2) middle pipe (8) partly with outer tube (7), so just make the spacing between co-axial outer tube (7) and the middle pipe (8) identical, water coolant flows between identical outer tube of spacing (7) and middle pipe (), the variation of flow velocity just can not appear, therefore, cooling performance to outer tube (7) is also just identical, the problem that can not cause part section cooling performance to weaken.In practice, our length of the back draught rifle body (2) that adopts is 6 meters.Actual outer tube (7) outside diameter that uses of back draught rifle body (2) is 299 millimeters, and end diameter is 273 millimeters; Middle pipe (8) outside diameter is 245 millimeters, and end diameter is 219 millimeters.Like this, the middle pipe (8) of described rifle body (3) and back draught rifle body (2) is identical with the distance between the outer tube (7), and this can make the backwater of water coolant, and the flow velocity in whole rifle body (3) is constant substantially, has guaranteed the whole cooling performance of rifle body (3).
Claims (1)
1. back draught oxygen rifle, include shower nozzle, rifle body and support, on the top of rifle body water inlet pipe and rising pipe are arranged, the bottom of rifle body is a back draught rifle body, described rifle body and back draught rifle body have co-axial outer tube, middle pipe and interior pipe, it is characterized in that: the middle pipe in back draught rifle body portion has identical tapering with outer tube.
