DE1769953B2 - DEVICE FOR ULTRASONIC DEFOAMING OF LIQUID - Google Patents

Description

One is shown in British Patent 1,075,100.

An apparatus for ultrasonic defoaming of liquids in Fig. 2 is shown a device for oblique Ultrasigkeit with an ultrasonic vibration plate 25 and sound-defoaming in which a described a Flüssigkeitumlenkplatte. The defoaming container 1 ', which from the same foaming liquid passes through an inlet in the manner of that according to FIG. 1 is, together with its a bath, rises on one side on the lowering vibration plate 5 'is arranged obliquely. It is just Flüssigkeitumlenkplafte upward and falls been found that the defoaming effect on the other side down to the DAJ by 30 three times as large as the horizontal Enteinen outlet which is \ with respect to Einlf slightly higher foaming tank 1 when the Container 1 'is arranged to leave. Since the ultrasonic relation to the horizontal plane at an angle irradiation of the liquid is arranged only in a part of 20 °.
