Abstract

The invention relates to a method for the controllable atomization of liquid for spray-bar irons, in which aerosolized liquid exits from the iron for the purpose of humidifying briquettes. The aim of the invention is a method in which the control function can be realized by an uncomplicated mechanism. The object of the invention is to use a principle for the atomization of liquid, in which a control of the amount of liquid emerging from the iron per unit time at constant Spruehstromgeschwindigkeit by controlling the aerosol parameters Kolloidteilchenzahl and / or size takes place. According to the invention, the object is achieved by using a per se known electromechanical ultrasonic atomization system for the aerosolization of liquid, wherein the aerosol parameters colloid particle number and / or size can be adjusted by controlling the frequency or amplitude of the ultrasonic velocity and the aerosol by per se known conveying means on the Buegelgut is being promoted.

Here, an atomizer with mixing device is used, the liquid and liquid vapor are fed separately · When operating the mixing device by means of a mechanical adjustment, the amount of vapor flow through the atomizer and thus the spray flow rate is set (DE-OS 2 023 66f, DE-ÖS 152 683) · ⁷ The main defect of this solution is that a relatively complicated mechanical device is used to control the spray current velocity.

Object of the invention

The aim of the invention is a method for controllable atomization of liquid for spray iron, which eliminates the disadvantages mentioned and in which the control function is realized by a simple, device-technically simple mechanism *

We , the invention

The object of the invention is to use a principle for atomizing liquid in which a control of the quantity of liquid leaving the iron per unit of time takes place at a constant spray flow rate by controlling the aerosol parameters of the colloidal particle number and / or size.

According to the invention the object is achieved in that a per se known / electromechanical Ultraschallzerstäubersystem for aerosolization of liquid verv / ends,

wherein the aerosol parameters colloid particle number and / or size can be adjusted by controlling the frequency or »amplitude of the ultrasonic oscillation and the aerosol is conveyed to the ironing material by means known per se«

Me invention will be explained in more detail with reference to an embodiment. In the accompanying drawing, the Pig "shows a sectional view of a Sprühbügeleisens® The spray iron consists of a soleplate 1 with aerosol outlets 2, multiple Aerosolverteilerkanälen 3» Aerosolierungsraum 4 with electromechanical Ultraschallzerstäubersystem 5 and connected to the Aerosolierungsraum 4 conveyor 6. In the operating state by the Electromechanical Ultraschallzerstäubersystem 5 aerosolized in the Aerosolierungsraura 4 existing liquid and pressed the aerosol by an externally controllable conveyor 6 through Aerosolverteilerkanäle 3 and 2 Aerosolaustrittsöffnungen on the ironing · As a conveyor 6, a blower can be used.

By spatial separation of the Ultraschallzerstäubersystems Lind the Plüssigkeitsreservoirs both the iron is easier and more manageable to make, as well as to achieve a continuous ironing with working humidifier for commercial purposes. The connection between the two parts of the device can be made by a flexible hose in which in addition to the electrical connections and the aerosol can be transported.
