There is a method of electric heating of the mixture and a device for its implementation [1]

The known method includes moving the mixture on the tray with exposure to a mixture of longitudinal oscillations and electric current and alternating compression and decompression of accessories longitudinally spaced sections of the electrode plates.

A device for electric heating of the mixture contains hopper mounted on shock absorbers, tray with wavy longitudinal plate electrodes and the oscillation exciter. Waves on the electrodes made with an offset from adjacent rows are out of phase by half a period.

A method of processing concrete mixes and device for its implementation [2]

The known method includes heating of the concrete mixture with simultaneous vibration when the ramp rotary percussive effects with changing amplitude.

The known device comprises suspended on cables, casing pipe with feeding hopper and the discharge box and the vibrator. The case contains a coaxial electrode of the three sections.

A device for processing concrete mixture [3]

The known device is vibroelectromechanical form. Casing-pipe is provided with a Central tube, supported at its lateral walls of the Central tube are positioned successively three coaxial electrode. Outside on the casing pipe attached vibrator. Known methods and devices do not allow for the intensification of the process in the processing of various concrete mixes and curing concrete.

The invention solves the problem of intensification of the process of improving productivity, reducing the material intensity energy intensity and increase the strength of concrete.

This is achieved by the fact that in the method of energoobekty concrete mixture comprising loading the mixture in a closed volume of vibroelectromechanical with three successive electrodes, elektromotoren while vibrating and moving the mixture to the discharge area and discharging the mixture, before loading inert components of the concrete mixture is mixed with a cement slurry processed in high-speed activator to activate clinker minerals cement, and the vibration is carried out by cyclically recurring shock-rotational effects, the amplitude of which varies in the direction of movement from 2.0 to 0.25 mm, and in the discharge area is 0.35 mm

The invention is illustrated in the drawing.

On the supporting walls 8 are installed pressure axial cross 10 with locking lugs. The crossbar 10 fixed frame beams 11, which are coaxial electrodes 12. Frame beams 11 are made of tokoprovodyascheho material, such as PCB. Housing tube 1 is made with an inspection hatch 13. For routine cleaning of the casing-pipe 1 from the remnants of sticky particles of concrete scraper in the lower part of the rear wall 8 made the hole 14. Fibrobacteres mounted on a support, which is made as a variant of the removable mounting in the form of vibroflotation base platform 15, provided with a hinged swivel console 16. On the console 16 install and secure the mounting bolts casing-pipe vibroelectromechanical. The rotation of the body-tube is provided and is fixed by a screw handwheel 17. In support of the platform 15

The process of energoobekty concrete mixture as follows.

To prepare concrete mix first get the cement dough with its simultaneous activation by a high-speed activation of clinker minerals in the activator (from 700 to 1400 revolutions per minute), then the mixer is activated cement paste mixed with other components of the concrete mix. Ready-mixed concrete is served in fibrobacteres in the hopper 2 and is subjected to electroresistive while vibrating and moving in the annular space of the shell-tube 1. The concrete mix when its motion is subjected to iterative rotary percussive effects, and the amplitude is changed in the direction of movement from 2.0 to 0.26 mm, and in the discharge area is 0.35 mm

Being in a confined annular space, the concrete mixture is subjected to intensive effects like thermal and physico-chemical due to the manifestations of a synergistic process, formed of conglomerate synergy based on the activation of the cement paste. Time involved elektromotoren carried out by vibroelectromechanical provides the intensity of the display area of each electrode to perform in the activated mixture, the implementation of physico-chemical chain reaction for the formation bystrovytsia structure of cement stone with the daily selling 70% and higher strength concrete.

Ready activated heated concrete mixture enters the electrodeless zone 3 the discharge area and the accumulation is discharged through the discharge window 4.

Coaxial electrodes vibroelectromechanical are made of material in accordance with the required calculation. Mounting frame-and-beam structure of the electrodes of vibroelectromechanical and its rapid change with the founding of the Central inner metal tube is by means of a clamping fixation of the tips of the axial crossbars 10 with the supporting walls 8. However, access to the implementation of the removal or connection of the electrical cable wiring to the electrodes is made through a removable hatch 13.
