Description

The invention relates to devices for producing emulsions and can be used in various industries to emulsify immiscible liquids.

The aim of the invention is to improve the quality of the emulsion.

Figure 1 schematically shows the device section; figure 2 - section aa in figure 1; on fig.Z - diagram of the device in the process unit.

The device consists of a rectangular mixing chamber 1 with a fitting 2 for supplying the initial components, made on the lid 3, fitting 4 for discharging the mixture. Inside chamber 1, in a plane perpendicular to its longitudinal axis, frames 5 are installed, having cutouts 6 on two opposite sides for placing metal rods 7, while the thickness of the frame is 0.1-0.2 mm greater than the diameter or height of the rod 7, and the cutouts b made with a tolerance of 0.1-0.2 mm for fixing the ends of the rods in a certain position.

In each subsequent frame, the rods 7 are rotated by an angle of 90 with respect to the rods of the previous frame, and the parallel rods are arranged vertically either one above the other or in a staggered manner, thus forming in the first case a straight channel for the passage of the mixture, in the second case - a curvilinear . Chamber 1 is connected to an installation that includes a working tank 8, a circulation pump 9, a metering tank 10 for a component of the mixture to be emulsified, such as bitumen, a pipe 11 with an electric or steam heating 12, communicating the circulation pump 9 with a chamber 1 and a pipe 13 with means for cooling it , connected at one end with the camera 1, and the other - with a working capacity of 8.

The device works as follows.

A liquid, for example water with an emulsifier, is poured into the working container 8. This mixture is pumped by a circulating pump 9 in a closed loop: working capacity 8 pipeline 11 - chamber 1 - pipeline 13 - working capacity 8. After water is heated to the boiling point, vaporization process begins, at which the volume of the steam-water mixture increases dramatically, resulting in an increased rate of passage of the mixture through chamber 1. Approximately 0.30.5 of the amount of water in the mixture evaporates. After that, the emulsifiable material, for example bitumen, is supplied from the dosing tank 10. With an increase in the speed of movement of the mixture, the free-lying rods 7 begin to vibrate. By adjusting the rate of passage of the turbulent flow of the mixture through the vibrating rods 7, the oscillation frequency is set, the rods, close to the natural frequency.

Thus, the turbulent flow, passing through the channels of the chamber 1 through the zone of resonantly oscillating rods, undergoes an emulsification process. After the mixture leaves the emulsification zone, it enters the cooled pipeline 13. where the steam condenses and the volume of the mixture decreases.

For difficult emulsifiable mixtures, it is repeatedly passed through chamber 1. The process is periodic. The finished emulsion is pumped into the supply tank (not shown ^).

Upon receipt of the emulsion in a single pass, the device operates in a continuous cycle.
