Summary of the invention
The utility model provides a kind of Multifunctional furnace wall coherent oxygen lance with compact construction of main oxygen accelerating sections for puzzlement and the prolongation oxygen lance blow head that solves Multifunctional furnace wall coherent oxygen lance bulkiness improves common Multifunctional furnace wall coherent oxygen lance work-ing life.Epoxy spray orifice and the gas jet orifice of common multifunctional furnace wall coherent oxygen lance are integrated to reduce volume, and main oxygen jet orifice independent design and adopt wear-resistant material, thereby slow down its rate of decay, increase the service life; Another its respectively advances Media Interface Connector and adopts the joint male end supporting with quick replace tubes pipe clamping device, can make coherent oxygen lance realize maintenance and replacing quick and sealing.
Multifunctional furnace wall coherent oxygen lance of the present utility model, be achieved through the following technical solutions: comprise oxygen lance blow head, main oxygen accelerating sections, epoxy tube, oxygen rifle mounting plate, gas line, main oxygen tube, main oxygen inlet suction port, the gas inlet joint, the epoxy inlet suction port forms, and main oxygen accelerating sections and main oxygen tube and main oxygen inlet suction port connect as one, and hollow forms main oxygen passage; Oxygen lance blow head is connected with gas line and gas inlet joint, and gas line inwall and the interchannel space of main oxygen and gas inlet joint and oxygen lance blow head gas jet orifice form blast tube; Oxygen lance blow head is connected with epoxy tube and epoxy inlet suction port, and the space between epoxy tube inwall and blast tube and epoxy inlet suction port and oxygen lance blow head epoxy spray orifice form the epoxy passage.
Further, the centre of described oxygen lance blow head is the through hole of laying main oxygen accelerating sections, is the gas jet orifice of ring-type outside through hole, is the epoxy spray orifice of ring-type outside gas jet orifice.
Further, described left side main oxygen accelerating sections endoporus adopts the Lavalle spray orifice, adopts the all-arc smooth structure, to obtain supersonic flow; Adopt the steel alloy material, strengthen its wear resistant corrosion resistant; Be welded and fixed at end face again after adopting shrink-fit to be positioned over the middle through hole of oxygen lance blow head, become the main oxygen jet hole; For guaranteeing that main oxygen accelerating sections endoporus more meets the Lavalle curve, adopt digital control processing.
Further, the described main oxygen accelerating sections outside one end and oxygen lance blow head interference assembling, the other end and main oxygen tube welding.
Further, the oxygen lance blow head set gas jet orifice and epoxy spray orifice, formed by machining after electrolytic copper forging and pressing.
Further, described main oxygen inlet suction port, the gas inlet joint, the epoxy inlet suction port adopts the male end joint that matches with quick replace tubes pipe clamping device with sealing groove.
Multifunctional furnace wall coherent oxygen lance of the present utility model, beneficial effect is: compact construction, small volume is convenient to installation and maintenance; Independently the main oxygen accelerating sections made of steel alloy has stronger wear-resistant corrosion resistance nature, and the endoporus that digital control processing goes out, the Lavalle gas flow hole flow curve of the theory of more fitting, can better keep the exit velocity of main oxygen jet and the longer winding-up distance that is difficult for dispersing is arranged, effectively improve oxygen rifle work-ing life, improve the utilization ratio of oxygen.
