Abstract
The utility model relates to a low-pressure air atomizing annular oil screen nozzle, composed of a casing, a gas nozzle, an oil nozzle, a screw device, a cock core, an air conditioning rotary hand, a connection tube, an oil supply adjusting rod, etc. The utility model is characterized in that an atomizing needle with a seat is arranged in the screw device; the periphery of the screw device is circumscribed with Archimedes spiral grooves; a plurality of small holes are drilled along the tangent line of the oil nozzle. The utility model has the advantages of stepped-up fuel oil atomization, sufficient combustion guarantee, high flame temperature, low noise, oil saving, capability of realizing automatic regulation and no carbon black; the utility model is suitable for fuel ceramic kilns.
Description
The utility model relates to a kind of low-pressure air annular oil screen nozzle that atomizes, and belongs to the nozzle class of oil burner; Be mainly used in the oil spout operation of the fuel oil kiln of ceramic electroceramics industry.
Present ceramic industry is used in the low-pressure nozzle of fuel oil kiln, all belongs to the single flow nozzle.Its operation principle is: fuel oil is after filtering with 1～1.5 kilograms per centimeter
2Pressure enters nozzle, atomize and burn required air or steam through the tangential swirl vane of air ejiction opening, be the swirling eddy ejection, under 75 °～90 ° the angle of cut, meet with the heavy oil stream thigh, force the heavy oil atomizing for burning with high-voltage high-speed.Practice shows: this kind smashes the nozzle that oil flows by high-voltage high-speed, is difficult to reach abundant spray burning purpose.Under the situation that strengthens oil mass, its fogging degree weakens, existing dirty oil, and carbon black obviously increases, and excessive fuel consumption also is fairly obvious.
The purpose of the present utility model is: a kind of low-pressure air annular oil screen nozzle that atomizes is provided.Wish that it realizes atomizing fully, burning fully, the no carbon black and the new type nozzle of fuel-economizing again.
This low-pressure air annular oil screen nozzle that atomizes, by shell (1), gas blowout head (2), oil nozzle (3), spiral organ (6), cock core (7), air conditioning revolve hand (8), take over (9), fuel feeding adjusting rod (10) forms, it is characterized in that being provided with in the described spiral organ (6) atomization needle (4) of a band needle stand (5), and cut archimedes spiral groove in the periphery of this spiral organ (6); Described oil nozzle (3) upper edge tangent line is drilled with 6 apertures (18).
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is an I portion enlarged drawing in the accompanying drawing 1.
Among the figure: 1, shell, 2, the gas blowout head, 3, oil nozzle, 4, atomization needle, 5, needle stand, 6, spiral organ, 7, revolve basic core, 8, hand is revolved in air conditioning, and 9, take over, 10, the fuel feeding adjusting rod, 11, bearing, 12, the O RunddichtringO, 13, fuel inlet fitting, 14, O RunddichtringO, 15, copper sheathing, 16, revolve hand, 17, six square nuts, 18, aperture, 19, the spiral of Archimedes groove
Below in conjunction with accompanying drawing, further describe the utility model.
Main points of the present utility model are: settle the atomization needle (4) of a band needle stand (5) in spiral organ (6), its needle end is stretched out spiral organ (6) and is visited in gas blowout head (3); And cut archimedes spiral groove (19) in the periphery of spiral organ (6), described gas blowout head (3) is drilled with 6 apertures (18) with the junction of spiral organ (6) along tangent line.
The nozzle of said structure, its operation principle is as follows:
When heavy oil with 1～1.5kg/cm
2Pressure, radially migrate along atomization needle (4) from atomizing needle stand (5) rear portion by oil duct, and the oil that sprays from oilhole is that 300～1000 millimeter of mercuries become umbrella shape curtain shape separately with pressure, this moment burns or the required air that atomizes enters air nozzle (2) by blower fan from the air port, through being located at six apertures on the oil nozzle (3), speed with 50～70 meter per seconds, warp sprays with the orientation that spiral organ (6) is 60 ° of angles, meet in the umbellate form position of atomization needle (4) with the oil phase that from oilhole, sprays, reach annular oil screen atomizing, send into the kiln combustion chamber.
On probation showing: the utility model is simple in structure, volume is little, atomizing is abundant, burning is complete.When using 100#～200# heavy oil, even the standard-sized sheet cock core does not have dirty oil and carbon deposit yet.
