Description

The utility model relates to devices for mixing materials and can be used in the construction, mining, food, medical and other industries.

A known analogue of the proposed utility model (patent for utility model No. 120581 publ. 09/27/2012 Bull. No. 27).

A device for mixing materials containing a mixing chamber mounted on a carrier and a rotation drive, characterized in that the mixing chamber is spherical in shape, and to prevent the formation of stagnant zones in the mixing chamber, the rotation drive is equipped with gears providing rotation of the carrier with the camera around a vertical axis and directly the mixing chamber around a horizontal axis.

The disadvantage of this device is the complexity of the implementation, which implies the use of three bevel gears, and the inconvenience of unloading finished mixtures from the chamber.

The closest analogue (prototype) is known (patent for a utility model of the Russian Federation No. 135536) of the claimed utility model, as the closest in combination of essential features.

A device for mixing materials containing a mixing chamber of a spherical shape mounted on a carrier and a rotation drive, characterized in that the rotation drive is equipped with gears providing rotation of the carrier with the camera around a horizontal axis and directly the mixing chamber around a second horizontal axis perpendicular to the first.

The disadvantage of this device is the lack of efficiency of mixing materials, as well as high metal consumption due to the presence of two bevel gears commensurate with the diameter of the mixing chamber.

A device for mixing materials that implements the effect on the mixed material in two mutually perpendicular horizontal directions is proposed.

The technical result of creating the proposed utility model is to increase the efficiency of mixing materials and reduce the metal consumption of the design of the device for mixing materials.

The technical result is achieved by the fact that the device for mixing materials contains a mixing chamber of a spherical shape mounted on a carrier, and a rotation drive equipped with gears providing rotation of the carrier around a horizontal axis and a mixing chamber around a second horizontal axis. The bevel gear for rotating the mixing chamber is complemented by a chain gear.

The resulting summing effect on the mixed material leads to an increase in the efficiency of mixing materials, and the presence of a chain gear will reduce the size of the bevel gears of the gear rotating the mixing chamber, and therefore reduce the metal consumption of the design of the device for mixing materials.

The utility model is illustrated by the drawing, which shows the kinematic diagram of a device for mixing materials.

The device consists of a rotation drive 1, which rotates the carrier 2 around the horizontal axis 3 by means of a cylindrical gear 4. In addition, the mixing chamber 5 is rotated directly with the loading hatch 6 around the second horizontal axis 7 by means of a bevel gear 8 with two chain transmissions 9.

The effect created by the device on particles of material in two mutually perpendicular directions leads to their mixing and destruction.

On the one hand, centrifugal forces are caused by the rotation of the carrier 2 with a spherical mixing chamber 5 fixed on it with respect to the horizontal axis 3. On the other hand, centrifugal forces are caused by the rotation of the mixing chamber 5 proper with respect to the second horizontal axis 7. Superposition of forces causes material particles to move along a complex path , which contributes to their intensive mixing.

The device operates as follows. The operating mode of the device for mixing materials is periodic. The source material, for example, a dry mixture, pigments through a feeder (not shown in the figure) and a loading hatch 6 enters the mixing chamber 5, which has a small diameter in order to avoid excessive loads on the bearing assemblies. One third of the volume of the mixing chamber 5 is filled with material through the loading hatch 6. After closing the loading hatch 6, the mixing chamber 5 is rotated with respect to two horizontal axes 3 and 7. The spherical shape of the mixing chamber 5 and the rotation frequencies are varied by means of gears 4, 8, 9 they are suitable for eliminating stagnant loading zones and increasing mixing efficiency, since a certain trajectory of frequencies gives rise to an optimal loading path for a given material. This helps to increase the area of contacting surfaces, the number of interactions and diffusion of materials, which will reduce the mixing cycle. The working phase ends by stopping the rotation drive 1 after a certain time interval and unloading the mixing chamber 5 through the loading hatch 6.

Effective unloading of finished mixtures can be done by installing a stationary unloading unit under the mixing chamber 5.

The cycle of mixing particles of the material can vary both for different materials, and to obtain a given quality of mixing the mixture based on pre-conducted experiments. This will vary the economic feasibility of the proposed device for mixing materials.
