Abstract

INSTALLATION FOR ACTIVATION OF CEMENT SLURRY comprising mounted on shock absorbers sealed container divided by horizontal partitions into sections equipped with emitters of ultrasonic vibrations of the membranes imagnitostriktsionnymi transducers installed along the perimeter sections of tubes and connections with shut-dispensing valves for inputting and outputting a cement slurry and a coolant and a discharging system connection, characterized in that, in order to increase the degree of activation and hope In each section, the radiators in each section are designed as a tank vertically installed along the axis, open at the ends of a tube of semi-cylindrical membranes with magnetostrictive transducers attached to their outer walls and entering from the bottom of the waveguide concentrator tube to the end of which is attached a magnetostrictive transducer with acoustic feedback, with the membranes being connected to each other and to the separating partitions with figured and ring inserts made of an elastic material.

Description

about

The invention can be used in the building materials industry to produce an activated cement slurry.

The aim of the invention is to increase the degree of activation and reliability of operation.

FIG. 1 shows an installation for activating a cement slurry, a slit; in fig. 2 shows section A-A in FIG. one; in fig. 3 - joint between membranes and gasket; in fig. 4 shows a waveguide concentrator with a magnetostrictive transducer with acoustic feedback.

The installation consists of a sealed container 1, mounted on shock absorbers 2 and having a fitting 3 for connection to a water supply system (not shown) and a fitting 4 for connection to sewage or other drainage devices (not shown), spherical bottom 5 equipped with a branch pipe 6 with a cork valve 7 and a spherical lid 8 equipped with a nozzle 9 with a cork valve 10 and a nozzle 11 with a cork valve 12. The container 1 inside is divided into separate sections by horizontal partitions 13 with central openings 14 and an annular casing 15 s 16. By logging annular rubber gaskets 17 and 18 are sealed vertically installed between the partitions 13, the emitters of ultrasonic vibrations in the form of the open ends of the semi-cylindrical tubes 19 with a sealing membrane shaped rubber gasket 20 attached between them and to their outer walls 21, magnetostrictive transducers.

From below, waveguide concentrators 22 with magnetostrictive converters 23 with acoustic feedback provided by two radiating packages 24 and receiving package 25, induced in which the feedback voltage is a signal for automatic oscillator frequency adjustment, enter the tubes of the radiators.

The installation works as follows.

Through the pipe 9 and the cork valve 10 with the valve 7 closed and valve 12 open, water-cement or other suspension is supplied to be activated, which enters the space between the semi-cylindrical membranes 19c by magnetostrictive transducers 21 and is subjected to ultrasonic vibrations of the same frequency acting oppositely to one another; and then under its own mass enters the concentrator-waveguide 22 with magnetostrictive transducers 23. The frequency of ultrasonic vibrations to which the water-cement suspension is subjected to the suspension differs from that of the magnetostrictive transducers 21. The water-cement suspension is a medium for cooling the magnetostrictive transducers 23, and the magnetostrictive transducers 21 cooled with water, which flows continuously into the container 1 through the nozzle 3, the tubes 16 and under the pressure is removed through the nozzle 4. Simultaneously Menno provided vacuum vessel 1 through the pipe 11 at the outdoor pith

0 RT In the second section, the activation of the water-cement or other suspension is similar. Co. the number of sections can be increased or decreased, they can be installed one below the other, in parallel or in combination

5 depending on the required; dimensions and the necessary degree of dispersion of solid particles, as well as the power of magnetostrictive transducers 21 and 23. The activation process is continuous. As the suspension accumulates in the zone

0, the bottom 5, the plug valve 7 is opened and the slurry is removed. Crane 7 serves as a regulator of its output. At the same time, the sealing of the tank 1 should not be disrupted. The cork valve serves as a similar regulator of the intake of water cement or other suspension.

ten.

At the end of the activation, the dilution system (not shown) is turned off, the water supply to the fitting 3 is blocked and water or chemical solution is supplied to the nozzle 9 when the tap 10 is opened, which are removed through the nozzle 6 when the tap 7 is opened. magnetostrictive transducers 21 and 23.

When resuming work, the processes recur.
