At present there is problems with water atomization pulverization:
1st, the water droplet backflow molten steel leak splashed when current intersect with molten steel collision, causing solidification of molten steel to block leak influences Production;
2nd, current primary fragmentation, the production efficiency of powder is not high, and the granularity of powder is uneven.
Utility model content
In order to solve the above problems, the utility model provides a kind of water-gas combined powder by atomization device, and the utility model passes through Following technical scheme realizes above-mentioned purpose:
A kind of water-gas combined powder by atomization device, including nebulizer body, the nebulizer body are provided with molten steel leak, extremely A few air inlet, at least one gas outlet, at least one water inlet and at least one water atomization outlet, the gas outlet is with entering Gas port is connected, and the water atomization outlet is connected with water inlet, the injection line focus position of the gas outlet and water atomization outlet In on the center line of molten steel leak, and the injection line focus of gas outlet is higher than the injection line focus of water atomization outlet.
Preferably, air slot and guiding gutter are additionally provided with the nebulizer body, the air slot connects air inlet and gone out Gas port, the guiding gutter connection water inlet and water atomization outlet.
Preferably, the air slot and guiding gutter are annular groove.
Preferably, protective case is provided between the molten steel leak and nebulizer body.
Preferably, annular is evenly equipped with multiple water atomization outlets on the nebulizer body.
Preferably, the water atomization outlet is water atomizing nozzle.
Preferably, annular is evenly equipped with multiple air inlets and water inlet on the nebulizer body.
Preferably, the gas outlet is the ring-crack ventilation air stream outlet gradually collapsed.
Preferably, high pressure draught, the water inlet input are ejected in the air inlet input gases at high pressure, the gas outlet High-Pressure Water is ejected in water under high pressure, the water atomization outlet.
The beneficial effects of the utility model are:
1st, water-gas combined atomization is the exploitation utility model on the basis of water atomization, by aerosolization combination water atomization, than Single water smoke dissolves powder efficiency high, and oxygen content in power is low.
2nd, provided with ring-crack ventilation air stream outlet, fine crack outlet is gradually collapsed, not only increases gas kinetic energy, and ring structures shape Into enclosed high pressure gas curtain, the water droplet backflow molten steel leak splashed when current collision is intersecting can be prevented, causes solidification of molten steel to block leakage Mouth influences production.
3rd, water atomizing nozzle annular is uniform in the utility model, then the current that water atomizing nozzle sprays are also that annular is uniform, Impinging air flows can be discharged from current gap, and partial high pressure disturbance will not be formed to air pressure inside.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is a-a sectional views in Fig. 1;
Fig. 3 is b-b sectional views in Fig. 1;
In figure:1 nebulizer body, 2 air inlets, 3 air slots, 4 molten steel leak, 5 protective cases, 6, water inlet, 7 guiding gutters, 8 Air-flow, 9 current, 10 ring-crack ventilation air stream outlets, 11 water atomizing nozzles.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described.
Embodiment 1
As Figure 1-3, a kind of water-gas combined powder by atomization device, including nebulizer body 1, set on the nebulizer body There are molten steel leak 4, air inlet 2, air slot 3, gas outlet, water inlet 6, guiding gutter 7 and 6 water atomizing nozzles 11;Molten steel leak Resistant to elevated temperatures protective case 5 is provided between nebulizer body;The air slot and guiding gutter are annular groove.The air slot with Air inlet is connected, and the gas outlet is connected with air slot;The guiding gutter is connected with water inlet, the water atomizing nozzle It is connected with guiding gutter.The gas outlet is the ring-crack ventilation air stream outlet 10 gradually collapsed, and 6 water atomizing nozzles annular is The injection line focus of cloth, the gas outlet and water atomizing nozzle is located on the center line of molten steel leak, and the spray line of gas outlet Focus is higher than the injection line focus of water atomization outlet.
In the present embodiment, the air inlet inputs gases at high pressure, and high pressure high energy air-flow 8 is ejected in the gas outlet, described Water inlet inputs water under high pressure, and high pressure high energy current 9 are ejected in the water atomization outlet.
This noodles making machine is mounted in the most crucial main part for water atomization pulverization on water atomization tower body, molten steel from After molten steel leak is vertically fallen, high pressure high energy air-flow primary fragmentation is first passed through, then by high pressure high energy current second-time breakage, it is real Existing air-flow current joint crushes powder processed, and prepared by liquid metal is metal dust.
Water-gas combined atomization of the present utility model is the exploitation utility model on the basis of water atomization, and aerosolization is combined Water atomization, improve water atomization present in some shortcomings, break-through skill mode, it is more more efficient than single water atomization go out powder.Air-flow After tentatively crushing, water cooling second-time breakage powder is lower than oxygen content in power prepared by single water atomization.
