A Witoshinski linear low-frequency ultrasonic large-angle multiple atomization nozzle

Abstract

The invention provides a Witoshinski low-frequency ultrasonic large-angle multiple atomization spray head, and the overall vibration direction of the spray head is the axial direction. The Witoshinski linear low-frequency ultrasonic large-angle multiple atomization nozzle horn of the present invention is a Witoshinski linear horn. Witosinsky horn has a large amplification factor, the metal used is small in size, stable in structure and less heat-generating, which overcomes the shortcomings of conical horns and stepped horns, which have large horn metal volume and high heat generation; The Sky horn has a large amplification factor, and as a whole horn, it overcomes the shortcomings of difficult connection of composite horns and unstable heating after long-term work. The present invention applies continuous pressure for a period of time at the water inlet pipe to continuously accelerate the mist droplets, and atomization occurs on the right end surface of the fan-shaped metal sheet, which breaks through the shortcomings of low-frequency ultrasonic atomization that is difficult to generate ultra-fine mist droplets and small angles, and can be used It is used in fields such as agricultural atomization cultivation and ultrasonic spraying.

Description

technical field [0001] The invention belongs to the field of atomization cultivation, and in particular relates to an ultrasonic atomization nozzle technology, in particular to a Witoshinski linear low-frequency ultrasonic large-angle multiple atomization nozzle. Background technique [0002] Ultrasonic nebulizer has a wide application prospect in the field of agricultural engineering due to its advantages of fine and uniform droplet size. Ultrasonic atomization refers to the use of high-frequency electronic oscillation, through the high-frequency resonance of the ceramic atomization sheet, to break up the molecular structure of liquid water to produce natural and elegant water mist, without heating or adding any chemical reagents. At present, the main shapes of the horn of the ultrasonic atomizing nozzle are conical, Bezier and stepped. The conical horn has a simple structure and is easy to design and manufacture, but its magnification factor is low; the stepped horn has a...

AI Technical Summary

Problems solved by technology

The ultrasonic transducer converts the high-frequency oscillating electrical signal into ultrasonic mechanical vibration, and the horn amplifies the amplitude of the sound wave generated by the ultrasonic transducer, creating a cavitation effect at the atomizing surface in front of the nozzle, atomizing the liquid, and at the same time A focused sound field is generated to suspend the steel ball, and the generated mist collides with the suspended ball to produce fine mist. This ultrasonic nozzle can only produce secondary atomization

Moreover, at this stage, most of the nozzles have small spray angles, the atomized droplets are too concentrated, and the spraying efficiency is low, which is not suitable for agricultural cultivation and ultrasonic spraying.
