Description

The utility model relates to devices for the continuous preparation of mixtures of bulk materials and can be used in food, chemical and other industries.

Known centrifugal mixer containing middle and outer cones, on the inner surfaces of which guide blades are spirally installed, having a number of holes and a circular arc profile (RU patent No. 2 246 343 C1 B01F 7/26 (2000.01) В28С 5/16 (2000.01)).

The disadvantage of this invention is the complexity of the design and low intensification of the mixing process of bulk materials.

The technical problem to which the utility model is directed is to simplify the design of the centrifugal mixer and increase the intensification of the mixing process of bulk materials.

The specified technical problem is solved by the fact that a fixed oval cone is installed inside the mixer body, which has loading and unloading nozzles, and inside it, a movable shaft is installed in the center, on which circular spreaders of different lengths are installed, and fixed circular receivers of different lengths are installed on the inner surface of the oval cone , moreover, the movable spreaders are made in the form of a cone from the shaft axis upwards, and the receivers are made circular and obliquely downward to the shaft axis.

The utility model is illustrated by a drawing, in which FIG. 1 schematically shows a general view of a centrifugal mixer, FIG. 2 is a section along the line A-A, in Fig. 3 - section along the line BB.

The centrifugal mixer (Fig. 1) contains a housing 1, in which a loading nozzle 2 is installed, in the lower part of which a four-beam support 3 (Fig. 2) is installed, which connects an oval cone 4 located inside the housing 1 and a loading nozzle 2. For better stability of the oval cone 4 in the inner part of the housing 1 of the centrifugal mixer there are fastening strips 5, 6. Inside the oval cone 4 in the center, in the hole 7 (Fig. 2) of the four-beam support 3, the shaft 8 is installed, on which the upper cone spreader 9 is located, the middle cone spreaders 10, 11 and the lower cone spreader 12. Along the inner surface of the oval cone 4 at an equidistant distance from the upper, middle and lower cone spreaders 9, 10, 11, 12 are located the upper circular receiver 13, the middle circular receiver 14, 15 and the lower circular receiver 16 . In the lower part of the oval cone 4, a four-beam support 17 is fixed (Fig. 3), which holds the shaft 8, and there are unloading nozzles 18, under which there are receiving containers 19 installed on the bottom 20. The housing 1 of the centrifugal mixer is mounted on racks 21, between which on the outside of the bottom 20 there is a gearbox 22, a clutch 23 and an electric motor 24, driving the shaft 8 in rotary motion with top, middle and bottom cone spreaders 9, 10, 11, 12.

The centrifugal mixer works as follows.

Bulk materials of various types are fed into the loading nozzle 2, installed in the housing 1 on the racks 21 (Fig. 1), passing through the four-beam support 3 (Fig. 2), connecting the oval cone 4 located inside the housing 1 and the loading nozzle 2, bulk material falls on the upper cone spreaders 9, located on the shaft 8, which is installed inside the oval cone 4 in the center in the hole 7 (Fig. 2) of the four-beam support 3. Due to the rotational movement of the shaft 8 from the electric motor 24 through the clutch 23 and the gearbox 22, a centrifugal force occurs , and the seeds entering the upper cone spreader 9 are moved to the upper circular receiver 13, located on the inner surface of the oval cone 4. Due to the inclined arrangement of the upper circular receiver 13, the seeds move to the middle cone spreader 10, from where to the middle circular receiver 14, from it to the middle cone spreader 11, then to the middle circular receiver 15, then to the lower end spreader 12 and to the lower pivot 16.

As a result of this movement of seeds inside the oval cone 4, there is an increase in the intensification of the mixing process of bulk materials, which from the lower circular receiver 16 enter the unloading pipes 18 with further movement into the receiving containers 19 installed on the bottom 20.
