The invention is intended for the preparation of the multi-component g; binders and mixtures used in foundry, construction, and other industries of the national economy. The goal (of the Invention is to intensify the processes of mixing the components of the mixture. The mixer includes a housing and a crushing unit, in the pins of which a pulsator is movably fixed, made in the form of a hollow shaft, equipped with nozzles, and in the center a partition alternately to the upper or lower end of the shaft. On the shaft, cones are fixedly mounted with rhombic perforation, the rhombi of which are oriented along a small diagonal along the generatrix of the cones, and The diameters of the diamonds are fixed, lamellar legs and angular dividers are fixed. The housing is equipped with a drain pipe - valve and gate valve. The components of the mixture are loaded into the housing through the hatch of the lid where they are mixed with discs; their pulsating vibrations that arise during the operation of the pulsator. After preparation, the mixture is discharged through the drain pipe. 8 an.

Description

The invention relates to devices for the preparation of multi-component binders and mixtures used in the foundry, construction and other branches of the national economy.

The aim of the invention is to intensify the mixing processes of the mixture components.

FIG. 1 shows a mixer with a local cut, general view; in FIG. 2, section A-A in FIG. one; in Fig, 3 - time cut BB on Fig, 2; in FIG. 4, the node: 1 in FIG. 2j in FIG. 5 — node II in FIG. 2; in fig. b - section bb of fig 4; in fig. 7; - section GGD; FIG. five; in FIG. 8, node III on IjbHr, 1.

The mixer includes a housing I of a cylindrical conical shape, closed by a lid 2, in the trunnions 3 a hollow shaft 4 is movably fixed with nozzles 5 in which the partition 6 is fixedly fixed to the ends and to the ends of which the compressed air pipe 7 is movably supplied

On the shaft 4, the cones 9 with rhombic perforation 10 are fixed with their vertices upward, whose diamonds are oriented along a small diagonal along the generator of the cones 9. The lamellar knives 11 and the corner dividers 12 are fixed at the perimeter of the perforation

 On the valve 2 of the housing 1, the actuator 13 is fixedly mounted with a bevel gear 14, the lid 2 has a hatch 15, and in the lower part of the housing 1 there is a drain nipple 16 with a valve 17,

; The mixer works as follows,

Inside the housing 1 through the hatch 15 in the lid 2 load the components of the mixture with their mechanical mixing- conical disks 9, driven in rotation by the drive 13, which are fixedly mounted on the hollow shaft 4.

After the loading of the components of the mixture in the housing 1 from the source of the round air is completed, air is supplied to the shaft 4 through the pipeline 7 through the interrupter 8,

Compressed air by the prelashitel 8 through the pipeline 7 is fed alternately to the upper or lower end of the hollow shaft 4, provided on the center of the

rod 6, and exits respectively through the upper or lower nozzles 5 inside the housing 1, filled with mixed components of the mixture. As a result, pulsating bubbling of the mixed components of the mixture occurs. Thereby, intensive mixing of the components of the mixture is carried out.

Simultaneously with rotation, when rotating the cones 9 with rhombic perforation of GO, around the perimeter of the rhombus of which, in the peripheral part of the disks, there are plate knives I1 on the top and bottom corner dividers 12, and in the center. Their upper parts are arranged with angle dividers 12 and lower blade knives 11, in the central part of the housing 1 along the shaft 4 there is an upward flow of mixing components of the mixture, and along their peripheral part and at the inner wall of the housing 1 there is a downward flow which consist of separate streams overlapping one another. As a result, the effect is observed

the addition of forces and there is an intensive mixing of the components of the mixture,

At the same time, the cones are divided into separate parts of the jets, which are immediately combined with other similar parts of the jets. These jets of the components of the mixture are formed and guided in the right direction with the help of lamellar knives II, and no larger corner dividers are members. The latter also contributes to the intensification of mixing processes of the components of the mixture.

The finished mixture through the pipe 16 with the open valve 17 is poured into the bunker of the finished product. The mixer is ready to recycle the mixture.

Claims (1)

Invention Formula A mixer comprising a housing within which perforated cones are mounted on a vertical shaft mounted for rotation, characterized in that, in order to intensify the mixing process, the shaft is hollow and provided with a source of compressed air, nozzles and a partition placed in the cross section of the shaft and dividing it into two parts each of which are connected to a source of compressed air, and the cones are provided with lamella knives and angle cutters, located around the perimeter of the cone perforations, so that the peripheral and central parts of the cones are equipped with flat blades, respectively, and the outer and inner surfaces, while the perforations are made in the form of rhombuses, the small diagonal of which is parallel to the generatrix of the cones.
