ATOMIZER FOR Application filed June 23,
This invention relates to a new and improved atomizer for oil burners.
One of the objects of this invention 1s t0 provide an atomizer and air supply device for oil burners whereby the amount of air of combustion supplied to the oil can be readily controlled.
Another object of this invention is to provide a device of this character in which the oil will be atomized more efliciently than in devices of this type which have been heretofore. known.
Another object of this invention is to provide an adjustable air cone in combination with atomizing apparatus for the oil whereby the necessity of providing nozzles of different sizes for different sizes of burners will be obviated.
Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment of this invention, it being understood that the above general statement of the objects of this invention is intended merely to generally explain the same and not to limit it in any manner.
Fig. 1 is a sectional view showing the new and improved apparatus.
Fig. 2 is a section on the line 22 of Fig. 1.
Fig. 3 is an end elevation of the air cone.
Fig. 4 is a side elevation showing the air and the adjacent pipe member.
Fig. 5 is a side elevation showing one of the vanes in the air cone.
The atomizer comprises a blower casing 1, in which a fan or blower 2 is mounted upon a hub 33. The hub 3 is suitably secured to the shaft 4, which is mounted in a bearing 5. The shaft 4 is provided with a worm 6 and this co-operates with the worm gear 7 mounted in the gear housing 8. The oil pump for supplying the oil to the burner is operated from the worm gear 7 in any suitable manner, this portion of the device being not illustrated as in itself it is old and well known and forms no part of this invention.
The shaft 4 is hollow and it is provided with an inner oil supply pipe 9 through which oil can be forced into the atomizing portion of the device. The oil supply pipe 9 is provided with a goose-neck 10 which is suitably secured thereto, so that the oil is delivered to the inner periphery of the atom- Y OIL BUBNEBS.
1926. Serial No. 117,986.
izer tube 11. rear threaded portion by means of which it is suitably connected to the. front of the shaft 4 so that the tapering atomizer tube 11. is revolved at high speed. The shaft 4 is turned at high speed in any suitable manner as, for example, by means of an electric m0-,
tor.
When the shaft 4 is turned at high speed, this causes the simultaneous rapid actuation of the blower 2. The supply of air which is admitted through the intake 12 to the blower 2 is controlled by means of the shutters 14 which can be of any suitable type. Theentire device is supported upon a furnace plate 15 which is preferably connected in any suitable manner to the furnace as, for example, by means of a hinge or the like. The air which is forced into the burner by the blower 2 passes through the air nozzle 16 which is surrounded by the outer sleeve 17. The air nozzle 16 is fixed and it is provided with an air cone 19 connected to an externally threaded pipe member 18.
As clearly shown in the drawings, the air cone 19 consists of an inner cylindrical part which is the end of the pipe 18, and an outer tapered part, the inner and outer parts or members of the air cone being connected by means of vanes 20. These vanes are inclined opposite to the direction of revolution of the shaft 4. Hence, the air which is forced between the vanes 20 encounters a thin film of oil which is forced out of the tapered revolving atomizer 11, the direction of movement of the air being opposite to the direction of movement of the thin film of oil. This combination causes the oil to be very eflicient'ly broken up.
The pipe 18 to which the air cone 19 is connected has a rear externally threaded portion by means of which it can be adjusted with respect to a support 20 which is suitably mounted adjacent the fan hub 3. However, the supporting member 20 remains stationary when the fan revolves. It is obvious that by adjusting the air cone 19 longitudinally that the amount of air which can be forced out of the air nozzle 16 between the end tapered wall of the said nozzle 16, and the correspondingly tapered air cone 19, can be regulated. A look nut 21 is provided for holding the cone 19 in the adjusted position.
In the position shown in Fig. 1 in which The atomizer tube 11 has a zle 16.
,the air cone 19 is illustrated as being at its extreme righthand-position, practically all the air is forced between the vanes 20. However, if the air cone 19 is moved to the left of this position, then air can be forced out between the outer surface of the air cone 19 and the inner surface of the noz- Experience has shown that it is advantageous to provide the air cone with the inner wall consisting of the end of the pipe '18, as well as the outer tapered wall, because the air which is forced between the vanes of the air cone does not sweep directly over the end of the atomizer tube 11.
Since the air does not sweep directly over the when, the cooling eifect of the air current on the thin film of oil within tube 11 is minimized.
- A preferred embodiment of this invention has been illustrated, but it is obvious that numerous changes and omissions could be made without departing from its spirit.
Claims.
1. An atomizer for oil burners comprising an air nozzle, means adapted to force airthrough said nozzle, a tube located within said nozzle and connected to a revoluble shaft, means adapted to feed oil into said tube so that the action of centrifugal force spreads said oil and ejects it in the form of a thin rotating film, an air cone located intermediate the inner wall of said nozzle and the outer wall of said tube, said air cone having an inner wall which is separate from the outer wall of said tube, said air cone having lateral vanes inclined in a direction opposite to the direction of rotation of said film.
the said air nozzle, the said air cone having inclined vanes, the inclination of the said vanes being opposite to the direction of rotation of the said film, and means adapted to blow air through the said air nozzle and air cone. 7
3. In an atomizer for oil burners, the combination of an air nozzle having a tapered mouth, an atomizer tube located in the mouth of the air nozzle and connected to arevoluble shaft,means adapted to feed oil to the said atomizer tube so that the revolution of the said atomizer tube will cause the oil to be forced out therefrom in the form of a thin rotating film,'and a movable member having inclined vanes connected thereto, the said vanes being inclined in a direc tion opposite to the direction of rotation of the said film, the said member being movable in a direction parallel to the axis of the air nozzle and having a surface which substantially corresponds to the contour of the tapered end of the air nozzle.
