Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can connects fast and use safe oxygen rifle, this oxygen rifle can be connected with oxygen belt with separated fast, avoid to greatest extent blast furnace to produce and impact, and elimination safety in production hidden danger, guarantee blast furnace man's personnel safety in use, reduce the consumption of oxygen hose simultaneously.The technical scheme solving the problems of the technologies described above is:
A kind ofly can connect fast and use safe oxygen rifle, it is by sheath, oxygen jet, oxygen hose, locknut, oxygen interface, oxygen burner forms, sheath is the sleeve that has through hole, insert from the front end of sheath through hole at the rear portion of oxygen burner, there is internal thread at the rear portion of sheath through hole, insert sheath through hole from the rear end of sheath through hole the front portion of oxygen jet, the middle part of oxygen jet has outside screw to be connected with the internal thread coupling at sheath rear portion, there is internal thread at the rear portion of oxygen jet, on oxygen jet central axial line, there is spray orifice, there is respectively outside screw the rear and front end of oxygen hose, the front end of oxygen hose with the rear portion of oxygen jet by being threaded, the rear end of oxygen hose is connected with locknut, the front end of locknut and oxygen interface is welded to connect, the rear end of oxygen interface is connected with oxygen belt.
Above-mentionedly can connect fast and use safe oxygen rifle, the internal diameter of the external diameter of described oxygen burner and sheath through hole closely cooperates, and the front end of oxygen jet is conical nozzle, and oxygen burner inserts in sheath through hole and is connected with the conical nozzle of oxygen jet.
Above-mentionedly can connect fast and use safe oxygen rifle, there is anticreep boss the rear end of described oxygen interface, fixing with iron wire binding after oxygen interface is connected with oxygen belt.
The beneficial effects of the utility model are:
The utility model adopts the connecting device of metal material that oxygen burner is connected with oxygen belt, connecting device adopts and is threaded, this syndeton makes oxygen burner can be connected fast, easily and safely with separated with oxygen belt, be convenient to change oxygen burner and carry out dismounting oxygen rifle, avoid the impact that blast furnace is produced, guaranteed blast furnace man's personnel safety in use, eliminated potential safety hazard, the use of also having saved oxygen hose, has significant economic benefit simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: sheath 1, oxygen jet 2, oxygen hose 3, nut 4, locknut 5, oxygen interface 6, oxygen burner 7, oxygen belt 8, anticreep boss 9.
Embodiment
The utility model is comprised of sheath 1, oxygen jet 2, oxygen hose 3, nut 4, locknut 5, oxygen interface 6, anticreep boss 9.
In figure, show, sheath 1 is for there being the sleeve of through hole, and there is internal thread at the rear portion of sheath 1 through hole.Sheath 1 plays protection oxygen jet 2 and the fixedly effect of oxygen burner 7.
In figure, show, insert from the front end of sheath 1 through hole at the rear portion of oxygen burner 7, and the internal diameter of the external diameter of oxygen burner 7 and sheath 1 through hole closely cooperates.
In figure, show there is spray orifice on oxygen jet 2 central axial lines, insert sheath 1 through hole from the rear end of sheath 1 through hole the front portion of oxygen jet 2, and the middle part of oxygen jet 2 has outside screw to be connected with the internal thread coupling at sheath 1 rear portion.The front end of oxygen jet 2 is conical nozzle, and oxygen burner 7 inserts in sheath 1 through hole and is connected with the conical nozzle of oxygen jet 2.There is internal thread at the rear portion of oxygen jet 2, for being connected with oxygen hose 3.
In figure, show, there is respectively outside screw the rear and front end of oxygen hose 3, and the front end of oxygen hose 3 is with the rear portion of oxygen jet 2 by being threaded, and the rear end of oxygen hose 3 is connected with locknut 5, locknut 5 is welded to connect with the front end of oxygen interface 6, and the rear end of oxygen interface 6 is connected with oxygen belt 8.
