Device for ultrasonic defoaming th with some 'embodiments of the invention of liquid with an ultrasonic vibration 5 two ways, three ways and five ways, respectively; plate and liquid baffle plates, thereby F i g. Fig. 4 is a cross-sectional view of an improved feature; that the ultrasonic vibrate embodiment of the device for the ultration plate (11) Sonic defoaming at an angle of 10 to 30 °, at which the liquid becomes Is arranged horizontally. deflection plates according to the invention inclined 2. Apparatus according to claim 1, characterized in that they are ίο net. indicates that the liquid baffles In F i g. 1 is a common horizontal device (16 to 19) at an angle of 60 to 80 ° or for ultrasonic defoaming with a container 1 100 to 150 ° to the ultrasonic vibration plate reproduced, which has two liquid deflection plates (11) are arranged. th 2 for guiding the liquid flow to 15 the flow path of the liquid to be defoamed ger, increasing the defoaming power or effect is increased. An ultrasonic vibration plate 5 is in front of the bottom of the container 1. The invention relates to a device seen through the vibrations or oscillations for ultrasonic defoaming of liquid with 20 the liquid is defoamed. The liquid will an ultrasonic vibrating plate and liquid through an inlet 3 into the container 1 and baffles. through an outlet 4 out of the container 1 One is shown in British Patent 1,075,100. Device for ultrasonic defoaming of liquids. 2 is an inclined device for ultra- sigkeit reproduced with an ultrasonic vibration plate and sound defoaming, in which a liquid baffle is described. The defoaming container 1 ', which of the same foaming liquid passes through an inlet in the manner of that shown in FIG. 1 is, together with its a bath, rises on one side on the lowering vibration plate 5 'is arranged obliquely. It is just a liquid baffle up and falls that the defoaming effect on the other side down, around the bath by 30 three times as great as with the horizontal _# Enteine outlet, which is slightly higher in relation to the inlet foaming tank 1 when the Container ί 'with 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 °. Bath counter to the movement of the liquid - With regard to the effect of the number of liquid Tet is the efficiency of the known Vor 35 keitumlenkplatten and their arrangement were how direction is not high, especially if it is also shown in FIGS. 3 A, 3 B and 3 C is shown, The flow rate of the liquid is greater than that by arranging one, two and four liquid suspension speeds, respectively the foam parts. baffles in the container two, three or The invention is based on the object of forming a five flow path, in which case the defoaming device for the ultrasonic defoaming of the fluidizing effect in three ways about 1.5 times this to create which is one compared to the two with two ways and with five ways, Known devices had significantly higher defoaming effects having. container with three ways more stable than in the other The task is performed by a device of one-container, so that the container · with three ways Initially mentioned type solved by the fact that the Ultra 45 is the most suitable and effective of this sound-absorbing vibration plate at an angle of 10 to mung tank turned out. 30 ° to the horizontal. Furthermore, if there is still a right angle to the vibration NEN the liquid baffle plate arranged in an angle liquid baffle with a from 60 to 80 ° or 100 to 150 ° to the ultrasonic to the perpendicular position with respect to the vibra vibration plate be arranged. 50 tion plate inclined liquid baffle plate Since the movement of the liquid in the bath is equalized, the defoaming effect is increased oblique direction to the ultrasonic radiation direction about 1.5 times the defoaming effect of the takes place is by the device according to the arrangement with the usually non-oblique flow invention a much larger defoaming baffle, with the liquid baffle effect achieved. This effect is due to the 55 th at an angle of 60 to 80 ° or 100 to Surface of the liquid baffles located 150 ° to the vibrating plate are arranged as it Foam parts, which is shown on the liquid baffle in Fig.4. The reason for this lies can easily move upwards, essentially because the inclined liquid baffle plate is there for strengthens so that the device according to the invention makes the foams light on the surface of the liquid invention an approximately five times larger defoaming 60 keitumlenkplatte and stick along the surface effect compared to the usual device with the liquid baffle to migrate upwards, horizontal bath is achieved. and in that the inclined liquid baffle The invention is effectively reflected in the following on the basis of the vibration.
