Description

The invention relates to the design of planetary mixers and can be used in the chemical, metallurgical, food, pharmaceutical and other industries, as well as in agriculture for mixing pasty, liquid and pasty materials.

The aim of the invention is to provide an intensification of the process, an increase in productivity, as well as an improvement in the quality of the finished product.

FIG. 1 shows a mixer with a housing in the form of a regular prism, a longitudinal section; in fig. 2 shows section A-A in FIG. one; FIG. 3 shows the dimensional ratios of parameters of the mixer J in FIG. 4 - one of the variants of mixing; in fig. 5 is a section BB in FIG. four; in fig. 6 is a sectional view BB in FIG. four; in Fig. 7 (o, (5, g, g, g, e,; t, |) are the positions of the mixers for one revolution of their axes around the fixed centers (through 45) in Fig. 5.

The mixer contains (Fig. 1 and 2) case 1, made in the form of a triangular prism, having a loading neck 2, for case 3 and discharge nozzle 4. In the case on crankshaft 5 connected to the electric motor 6, the hinged pinned is made in In the form of a screw, a stirrer 7, the axial projection of which has the shape of a double circular segment (dimensional relationships in Fig. 3). The agitator 7 is rigidly coupled to the satellite 8, which is kinematically connected to the internal gear 9, which is fixed on the top of the 3 mixers.

FIG. 4 shows a mixer, the casing of which has the shape of a hexagon, obtained by sequentially attaching the correct triangular prisms, with the exception of adjacent faces. As in the above described embodiment of the mixer, its body has a loading neck 2, a cover 3 and an unloading nozzle 4. In the case 1 there are mounted agitators 7, the axial sections of which have the shape of a double circular segment, and the major axis of the section of each mixer is perpendicular to the corresponding axis. m two adjacent agitators (figure 5).

The mixers are mounted for rotation around the axles 5, with knees in the upper part, whose necks are hinged in the lid 3

mixer One of these mixers is rigidly connected to the satellite 8, and its crankshaft is connected to the engine 6. The possibility of a planetary motion of this mixer is also provided by

as in the previous case, with the help of a single-stage planetary gearbox, which includes, in addition to satellite 8., pivotally mounted on the crankshaft connected to the engine, the fixed gear wheel with internal gearing 9.

The possibility of the same movement of the remaining agitators is provided by means of a gear-lever mechanism (Fig 6) consisting of a leash 10, which is hingedly mounted on the throats of the agitators 7, the central gear 11 mounted for rotation

relative to the geometric center of the driver 10, and six identical gears 12, which are in engagement with the gear wheel 11 and are rigidly connected to the agitators 7. In this case

the leash 10 also serves as a protective cover of the gear-lever mechanism.

The mixer works as follows.

The rotational movement from the electric motor 6 (Fig. 1) is brought to the neck of the crankshaft 5. At the same time, the satellite 8 hinged on it, the gear with the internal gear 9, will simultaneously rotate around the axis 5, ensuring a hard planetary movement the agitator 7 connected to it,

Mixer with a body in the form of a regular hexagonal prism

(Fig. 4) works in a similar way, with the planetary motion of one of the mixers (which is rigidly connected to satellite 8) being transmitted to the remaining mixers by means of a gear-lever mechanism as follows (Fig. 4. 6). The leash 10, having made a parallel-parallel motion, transmits an eccentric movement of the crankshaft axis associated with the engine on the axis

the remaining mixers. The rotational movement of these agitators around the axles 5 is achieved by means of a kinematically interconnected toothed wheel.

forests 11 and gears 12, one of which is leading. Each mixer in its movement detects the volume of one of the triangular prisms, of which the mixer body shape is formed, and all the mixers (Fig. 7) completely eject the working volume of the mixer for one turn of their cranked axles 5 on the material being processed.
