Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a liquid fuel atomization device that atomizes liquid fuel using an ultrasonic vibrator.

(Prior art) A conventional ultrasonic vibrator-type liquid fuel atomization device is
An ultrasonic vibrator is attached to the bottom wall of the atomization chamber, and an oil level device is used to maintain the oil level in the atomization chamber at an appropriate constant level, and the ultrasonic vibrator is was vibrated to irradiate ultrasonic waves into liquid fuel such as white kerosene to atomize the liquid fuel.

(Problems to be solved by the invention) This conventional liquid fuel atomizer has the problem that the electric circuit configuration is extremely complicated in order to change the amount of atomization and achieve so-called proportional control. Ta.

In view of the problems of conventional liquid fuel atomization devices, the present invention has developed a liquid fuel atomization device that uses a new atomization amount control method to proportionally control the amount of atomization without requiring complicated electrical processing. The purpose is to provide an atomization device.

(Means for solving the problem) In order to achieve this objective, the present invention has the following configuration. That is, the liquid fuel in the atomization chamber is kept at a constant oil level by a constant oil level device, and the distance from the ultrasonic vibrator to the oil level is changed by moving the support body equipped with the ultrasonic vibrator up and down. I have to.

(Function) When atomizing liquid fuel by irradiating ultrasonic waves with a constant output into liquid fuel, when the distance from the ultrasonic transducer to the oil surface is a certain optimum dimension (H), the maximum The amount of atomization can be obtained, and as the size is reduced below this optimum size (H), the amount of atomization decreases, and as the size approaches the optimum size (H), the amount of atomization increases. Therefore, if the oil level is kept constant and the position of the ultrasonic vibrator is moved up and down, the distance between the ultrasonic vibrator and the oil level will change, and the amount of atomization will change accordingly. By controlling the moving distance of this ultrasonic transducer, the amount of atomization can be controlled.

(Example) An example of the present invention will be described with reference to the drawings. The figure shows a schematic configuration of an embodiment of the present invention, in which numeral 1 denotes an atomization chamber, which is connected to a burner head 2. Reference numeral 3 denotes an ultrasonic vibrator, 4 a support body with the ultrasonic vibrator 3 attached to one end, and the other end forms a valve body 6 of an air volume control valve 5. Reference numeral 7 designates a solenoid provided below the atomization chamber 1, and the central portion of the support body 4 forms the iron core of the solenoid 7. Reference numeral 8 denotes a blower, which is connected to the air volume control valve 5. 9 communicates with the air volume control valve 5, and the atomization chamber 1
This is an air supply pipe that opens above the oil level inside.

In the liquid fuel atomization device described above, the liquid fuel in the atomization chamber 1 is controlled by the constant oil level device (not shown) to the optimal dimension between the ultrasonic vibrator 3 and the oil level that provides the maximum amount of atomization. H), the oil level is maintained at a constant level, and oscillation output is given to the ultrasonic vibrator 3 to irradiate ultrasonic waves into the liquid fuel to atomize the liquid fuel.
By controlling the power applied to the solenoid 7 and moving the support body 4 up and down to change the distance h between the ultrasonic vibrator 3 and the oil surface, the amount of atomization can be changed, and the distance h can be made shorter than the optimum dimension H. The more the atomization amount decreases, the more the valve body 6 at the other end of the support body 4 narrows the flow path of the air volume control valve 5, so the supplied air volume also decreases. Therefore, it is possible to control the amount of atomization by controlling the distance h between the ultrasonic vibrator 3 and the oil surface, and also control the supply air volume at the same time, so that a suitable air-fuel mixture is always created in the atomization chamber 1. It can then be sent to the burner head 2.

(Effects of the invention) This invention maintains the liquid fuel in the atomization chamber at a constant oil level and controls the amount of atomization by changing the distance from the ultrasonic vibrator to the oil surface. This method has the advantage of being able to perform proportional control of the atomization amount, which is simple and has a wide range of applications, without requiring any manual processing.
