Abstract

The essence of the solution is that the output channel is of a smaller diameter than the converter and the output channel is equipped with a mesh.

Description

The present invention relates to an ultrasonic device for continuously mixing and homogenizing liquids.

So far known ultrasonic devices for mixing and homogenizing liquids work in such a way that the treated liquid bypasses the working tool continuously and then flows out of the working vessel. A drawback of these devices is that a low homogeneity of the liquid to be treated is achieved, the removal of the various agglomerates in the treated liquid is not achieved, therefore it is necessary to pass it through the working vessel several times, thereby substantially prolonging the processing time.

The above-mentioned drawbacks are solved by a technical problem solved by an ultrasonic device for continuously mixing and homogenizing liquids according to the invention, the essence of which is that the outlet channel is of a smaller diameter than the diameter of the active part of the ultrasonic transducer or its working tool. The outlet channel is fixed with a mesh. Preferably, the reflecting surface in the working vessel is adjustable. The outlet channel is advantageous in the form of a cavity with a lateral outlet.

An ultrasonic device for continuously mixing and homogenizing liquids according to the invention achieves a high homogeneity of the liquid to be treated, dispersing all the aggregates and substantially reducing the processing time.

In the accompanying drawing, an exemplary embodiment of an ultrasonic device according to the invention is shown where it is drawn in section.

An ultrasonic device for continuously mixing and homogenizing liquids consists of an ultrasonic transducer 1 which is screwed onto the upper face of the funnel-shaped working vessel 7. Under the lower face 8 of the ultrasonic transducer 1, a reflecting surface 2 is adjustable in the working container 7. A working gap 9 is formed between the lower face 8 of the ultrasonic transducer 1 and the reflective surface 2. On the reflective surface 2, a cavity-shaped outlet channel 4 is provided, The outlet channel 4 is of a smaller diameter than the lower face 8 of the ultrasonic transducer 1 and is provided with a mesh 3 at the level of the reflecting surface 2. The upper face of the working vessel 7 is provided with two liquid inlets 5. Upon oscillation of the ultrasonic transducer 1, a liquid is introduced through the inlets 5, which is thoroughly mixed with the necessary emulsion or suspension by passing through the working gap 9 and the mesh 3. An exemplary embodiment of the device provides for double utilization of the ultrasonic energy in contact with the liquid, both in the working gap 9 and in the cavity of the outlet channel 4 below the side point 6.
