RU25427U1 - ULTRASONIC MIXER - Google Patents

Abstract

An ultrasonic mixer containing a steel body, which contributes to an increase in the density of ultrasound, with an inlet, an annular nozzle and a resonant system of plates located exactly opposite the nozzle slot, coaxially to it, characterized in that the resonance system can have a different number of plates, each of which has its own resonant frequency.

Description

The invention relates to equipment for obtaining

emulsions.

The use of sound and ultrasonic vibrations is one of the methods of influence on many physical

   -....,. ,

and chemical processes used in industry. Ultrasonic vibrations provide a significant acceleration of technological processes, which cannot be achieved using such widespread methods as mechanical mixing, exposure to high temperatures and pressures, etc.

As it is known, when emulsions are obtained using ultrasound, intensive fragmentation and mixing of particles of dissimilar liquids takes place. Currently, highly dispersed, homogeneous and concentrated emulsions are of particular interest for a number of technological processes. The production of such emulsions on an industrial scale is possible only with the help of ultrasound.

For the process of formation of various types of emulsions, a different threshold value of the ultrasound intensity is required, below which emulsification does not occur. Therefore, it is essential to achieve high intensities of ultrasound.

Known ultrasonic devices for producing emulsions - R (/ Patent No. 097118 C1 class. 6 B 01 P, 1998 r., BU No. 2033856 C1 class. 6 V 01 F 11 / 0.1990, SUP 075341 C1 class. 6 V 01 F 11/0 1997r, Bi; No. 091151 C1 class b 01 F 11/0, 1997 and others.

The disadvantages of these devices for producing emulsions are the high energy intensity, the presence of a source of ultrasonic vibrations or the inability to change the frequency of oscillations of the mixture flow during emulsification in a simple way at a constant pressure, since this requires additional devices - adjustable chokes, etc., and you cannot get different types emulsions with different viscosities, because this requires a change in the operating modes of the equipment.

The proposed ultrasonic mixer allows you to get an intense acoustic field through the use of a system of vibrating elements - plates - 1. Depending on the tasks, the number of plates can be different. The plates can have different natural frequencies, which allows to obtain emulsions of different viscosities, In case 2, made so that it contributes to an increase in the density of ultrasound, an annular nozzle 3 is installed coaxially to the vibrating plates. The applied method of fastening the vibrating system allows quick and easy it is easy to replace it when running out of resources.

The device is notable for its simplicity of design, low cost, intensive mixing of the medium and at the same time allows to obtain an intense acoustic field.
