Description

one

The invention can be used in the building materials industry and relates, in particular, to the structures of vibrated concrete mixers.

Forced-mixing vibro-concrete mixers are known, which contain a casing mounted on a frame by means of shock absorbers with a vertical vibrating tool and stirring, additional screw-type agitators with individual drives around it.

The purpose of the invention is to improve the design, increase the mixing efficiency and reliability of the mixer. For this, each of the additional screw agitators with an individual drive is mounted on a console hinged to the body, it is console, and all the consoles are connected to the shaft, it is a flexible transmission with a reversible drive.

FIG. 1 shows a section mixer; in fig. 2 - the same in terms of.

The vibratory mixer contains a cylindrical body 1 mounted vertically on the frame by means of elastic supports 2, a rigid cruciform frame 3 connected to the body 1 by means of springs and springs 4. The main drive 5 with the central working body 6 and the vibrator 7 are mounted on the frame 3 6 is hollow, and nozzles 8 and 9 are attached to it of different lengths for introducing an aluminum suspension into the mixture. Several cylindrical hinges 10 are vertically attached to the outer surface of the housing 1, on which horizontal consoles 11 are mounted, equipped with auger agitators 12 and electric motors 13 mounted relative to the housing 1 but its outer circumference. The agitators 12 are kinematically connected to the electric motors 13 by means of a V-belt transmission 14. The consoles 11 are connected to the reverse actuator 15 by means of an axle gear and a chain gear 16 to it.

Vibration mixer works as follows. Using a pneumatic drive 15 and a common chain transmission 16 of the console 11 synchronously make a reciprocating and unavailable movement in the horizontal plane in sharpieres 10, and the screw agitators 12 in this case describe the trajectory along a circle, the center of which is the hinges 10.

The siliceous component slurry and the required amount of water are loaded at

rotation of working orgap 6 and agitators 12 in the absence of vibration. Then the vibrator 7 is turned on, vibrating the frame 3 with the central working body 6, and loaded into the shear.

Working body 6 simultaneously cuts

and vertically moves the mass, creating an upward flow of the mixture, and agitators 12 - downward flow of the mixture at high speed. By simultaneously rotating and synchronously moving the agitator agitators around the circumferences, intensive mixing and thixotropic dilution of the mixture throughout the volume of the mixer is carried out.

After the download is complete, without the cessation of vibration, aluminum powder in the form of a suspension is added to the mortar mixture. The suspension enters under pressure into the rotating hollow shaft of the working body 6 and is injected through the nozzles 8 in the lower part upward reaching the average volume of the mixture, and through the pipes 9 into the upper part downward reaching the outer volume of the mixture.

Subject invention

The forced-mix vibrating concrete mixer containing installed on

frame by means of shock absorbers, a housing with a vertical vibrating working body and additional worm-mounted agitators placed around it with individual drives, characterized in that

in order to simplify the design, increase mixing efficiency and reliability, each of the additional screw agitators with an individual drive is mounted on a swing arm that is hinged to the body, all consoles connected by a common flexible transmission with a reversible drive.
