(5) INSTALLATION FOR CEMENT ACTIVATION

This invention relates to the field engineering, in particular, to installations for the activation of cement and the preparation of a cement suspension.

According to the main author. St. No. 906712 is a known installation for activating cement, containing a frame with shock absorbers and installed one above the other section, interconnected by pipelines with hydrodynamic emitters, vibrators mounted on a frame in mutually perpendicular planes, the sections being connected to pneumosuperity and vacuum forming systems Cl} .

A disadvantage of the known device is the low degree of dispersion.

The purpose of the invention is to increase the degree of dispersion.

This goal is achieved by the fact that the plant for cement activation is equipped with reflectors installed under the hydrodynamic / trainers, made in the form of coaxially arranged sleeves, the outer of which is made rotatable and has tapered holes arranged in a checkerboard pattern, with a smaller base facing the an inner bushing, made with conic-shaped apertures located along its forma- tion, with a smaller base facing the outer bushing, and the reflectors are made and plates arranged at an angle to the vertical with a gap therebetween.

FIG. 1 shows the proposed installation, the general view; in fig. 2 hydrodynamic radiator.

The cement activation plant consists of a space frame 1, which is mounted on shock absorbers 2. Vibrators of vertical vibrations 3 and horizontal vibrations T are attached to the spatial frame of the gesture20. Capacities mounted from the upper 5 and lower 6 hermetic sections installed one above the other, to which pressure is applied by means of pipelines, are installed on the upper part of the spatial frame. from pneumosuppressive and vacuum systems (not shown). Both sections are interconnected by pipelines. To ensure the alternate supply of pressure and vacuum, the sections have shut-off and dispensing valves in the form of cork taps 7 and 8, and for supplying liquid or water-diluted additives - a similar valve 9. The stop-distributing valves 10 are installed in pipe 11, filling the volume with a water cement slurry, and a similar cork valve 12 closes the pipeline 13 to remove the activated cement. In the tanks above the water-cement slurry at the end of the pipelines 14 and 15, emitters (representing coaxially arranged rotatable outer 16 and inner 17 sleeves (not shown) with cone-shaped openings 18 of the inner bush 17, located inwards along one line, parallel to its generatrix, and with the same cone-shaped openings 19 of the outer sleeve 16, rotated in the opposite direction (base out) and placed in a checkerboard pattern. The reflectors 20 consist of two steel plates, with a gap and at an angle to the vertical. The unit for activating cement works as follows: Through pipe 11 and the cork valve 10, section 5 is supplied with a water-cement suspension, which, under the action of atmospheric pressure, enters section 5 through the cork tee 8, which is in the position blocking the pipeline connecting the atmosphere with section 6. In the presence of vacuum in section 6 (vacuuming is performed at the position of valve 7. providing air suction from section 6 with the pipe blocked connecting valve 7 sec. Section 5 under the action of the pressure difference through conduit 15 and the emitter 16 after ultrasonic activation enters the reflector 20 and fills section 6. From section 6 under the action of pressure differences (section 5 is evacuated, and section 6 is connected to the atmosphere) the pipeline with the cork valve 9 enters the pipeline C with the radiator 16, hits the reflector 20 and zagulnay section 5. Then the volume of section 6 is evacuated, and section 5 is connected with the atmosphere, and the process repeats. After the estimated number of activation cycles, the activated mixture is removed through conduit 13 with the cork cock 12 open. Through the pipe 11 and the cork cock 10, a new portion of the water-cement slurry is fed to section 5, and the process is repeated. Applying the invention by 20 will increase the economic efficiency of using the installation, i.e. additional annual economic effect of 20 thousand rubles. The invention The installation for the activation of cement according to ed. St. No. 906712, characterized in that, in order to increase the degree of dispersion, it is equipped with reflectors installed under hydrodynamic radiators, made in the form of coaxially arranged vt1gak, the outer of which is made rotatable and has cone-shaped holes arranged along the length in a checkerboard pattern, facing the smaller base to the inner sleeve, made with conical holes arranged along its formative, smaller base facing the outer sleeve, and the reflectors are Enes from plates installed at an angle to the vertical with a gap between them.
