SU1235521A1 - Apparatus for dispersing mixtures - Google Patents

Description

The invention relates to the technique of dispersing mixtures, such as emulsions and suspensions, and can be used in various industries, in particular for the preparation of heat-resistant concrete of increased strength and accelerated hardening for industrial and special purposes.

The purpose of the invention is to increase the intensity of the dispersion process.

FIG. 1 shows a device for dispersion, a cross-section; in fig. 2 shows section A-A in FIG. one.

The device for dispersing the mixtures comprises a housing 1, a stator 2 and a rotor 3, on which protrusions 4 are installed, which are not in the form of an elliptical shape 5, a movable disk partition 6 consisting of three plates 7-9, of which 8 can be rotated with respect to the shaft at a certain angle and fixed with a hammer 10, the disk partition is provided with holes 11. The impeller 12 is mounted on the shaft 13.

The proposed device works as follows.

The worked-out visco-plastic mixture enters the space between the protrusions 4 of the stator 2 and the rotating disk partition 6 with holes 1 1 as well as the rotating rotor 3. This creates intense high-frequency turbulent pulsations and waves many times larger than its parameters in the waves and ripple in the design without a special disk partition. The processed multicomponent emulsion or suspension, entering the space between the disk partition and the rotor, is subjected to the additional effect of strong wave oscillations, which contribute to the additional dispersion of the mixture. Turbulent mixture pulsations and intensive wave fields cause active cavitation processes in the liquid, which promote the formation of fine and highly homogeneous emulsions and suspensions.

When solid foreign unprocessed inclusions get into the multicomponent flow, the movable disk partition moves reciprocatingly

along the longitudinal axis of the shaft, the foreign inclusions then fall to the bottom of the device, and then are removed.

Depending on the need for different turbulent pulsations and waves, as well as the required degree of dispersion of the multi-component mixture being processed, the holes in the movable disk partition can be adjusted by rotating the middle plate and fixed with a pin in a certain position from close to full open).
