Witozinsky line type low-frequency ultrasonic large-angle multi-atomization sprayer

Abstract

The invention provides a Witozinsk line type low-frequency ultrasonic large-angle multi-atomization sprayer, and the overall vibration direction of the sprayer is an axial direction. An amplitude-change pole of the Witozinsk line type low-frequency ultrasonic large-angle multi-atomization sprayer is a Witozinsk line type amplitude-change pole. The Witozinsk line type amplitude-change pole is large in amplification coefficient, small in volume of used metal, stable in structure and low in heat generation and can overcome the defects that a conical amplitude-change pole or a step type amplitude-change pole is large in metal volume and high in heat generation; the Witozinsk line type amplitude-change pole is relatively large in amplification coefficient and the overall amplitude-change pole overcomes the defects that a composite amplitude-change pole is difficult to connect and unstable in heat generation after working for a long time. According to the Witozinsk line type low-frequency ultrasonic large-angle multi-atomization sprayer provided by the invention, a water feeding pipeline is applied with a continuous pressure for a certain time so that fog droplets are continuously accelerated and are atomized at the right end face of a fan-shaped metal sheet, so the Witozinsk line type low-frequency ultrasonic large-angle multi-atomization sprayer breaks through the defects that superfine fog droplets and a small angle are hard to generate by low-frequency ultrasonic atomization, and can be applied to the fields such as agricultural atomization culture 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.
