Description

(54) MIXER

The invention relates to mixers for the preparation of mixtures and can be used in the chemical, food, agricultural, pharmaceutical and other industries. A mixer containing a closed drum mounted on the base is pivotally fixed at two ends in fork supports, one of which is pivotally connected to the drive shaft and the other is pivotally mounted on the rotating axis C. The closest in technical essence and the achieved result Jk. The proposed invention is a mixer containing a frame in which a drum is fixed, equipped with a rotational drive, by means of a bevel gear pair / fixed on a shaft mounted in bearings on a frame. By changing the position of the drum in the space in all three planes in this device, a more complete t2J is achieved. However, this mixer does not provide a sufficient degree of mixing intensity and does not create thin; homogeneous mixtures. The purpose of the invention is to increase the intensity of mixing, to obtain thinner homogeneous mixtures. The mixer can homogenize liquid booms, mix powdered materials, be used when mixing liquid-solid systems, to prepare emulsions used in agriculture for spraying. The goal is achieved by the fact that a mixer, containing a frame, in which a drum is fixed, equipped with a rotational drive by means of a conical toothed pair, mounted on a cutting shaft, mounted in Hei bearings, and equipped with a mixing body mounted on a drum shaft with a conical wheel interacting with the drum drive gear and an additional drive frame covering the first frame and rigidly mounted on the drive shaft mounted in the bearing oh on the bed, the first frame being installed in an additional one with the possibility of rotation, and

the rotation drive of the first frame is made in the form of a conical gear pair, the drive wheel of which is rigidly fixed on the frame.

The drawing is a schematic representation of a mixer. The mixer contains on the base 1 in bearings 2 an installed drive shaft 3, to which an additional frame 4 is rigidly fixed. Inside the additional frame on bearings 5 of the shaft there is a nonlen shaft b, to which the frame 7 is rigidly fixed the supports are mounted to a drum 8, equipped with a shaft 9, on the cantilever end of which a conical wheel 10 is fixed, which interacts with a neck-11, rigidly fixed on the drive shaft 3, a mixing body 12c is placed in the cavity of the drum 8 mounted on its shaft with a conical wheel 13, interacting with gear 11. An additional frame 4 covers the frame 7 having a rotational drive, made in the form of a conical gear pair 14 and 15, the drive wheel 15 of which is rigid. . Fixed on the bed 1.

The drum is made in the form of two truncated cones having a common larger base. The inner surface of the drum is provided with opposing screws grooves, and the loops of the mixing body have a slope opposite to the slope of the turns of the grooves.

The mixer works as follows. When the drive is turned on (not shown), the drive shaft 3 begins to rotate the frame 4. In this case, the bevel wheel 14 rolls around the bevel gear 15 and transfers the rotation to the shaft 6, which rotates when the water frame 7 has a mixing drum. Bevel gears 10 and 13 roll around the gear 11 and transmit the rotation to the shaft 9 of the drum and the shaft of the stirring member 12. The shaft of the stirring member 12 and the shaft 9 of the drum rotate in opposite directions. The entire intraframe system with frame 4 and six. The p. 11 rotates with shaft 3.

Thus, the drum mixer rotates around three axes with simultaneous rotation in the opposite directions of the mixing organ and the drum, which creates highly efficient conditions for mixing and producing thinner homogeneous mixtures.

Formula, inventions.

A mixer comprising a frame in which a drum is fixed, provided with a rotational drive through a conical gear pair mounted on a drive shaft mounted in bearings on a frame, characterized in that, in order to increase the intensity of mixing and to obtain thinner homogeneous mixtures, it is provided with the cavity of the drum mixing body with a cantilever mounted on the shaft of a conical wheel that interacts with the drive gear of the rotation of the drum, and drive the additional frame, covering the singing frame and rigidly mounted on the drive shaft mounted in bearings on the frame, the first frame being mounted extra rotatably, and the rotational drive of the first frame is made in the form of a conical gear pair, the drive wheel of which is rigidly fixed on the frame.
