Description

Phie.1

The invention relates to vibration mixers used to prepare high-quality composite loose particulate compositions, and can be used in powder metallurgy, chemical, construction and other industries.

The purpose of the invention is to increase the quality of the finished product and the service life of the mixer.

FIG. 1 shows the proposed vibrating mixer, cut; in fig. 2 is a view A of FIG. one; in fig. 3 - capacity of vibromixer, cut; in fig. C - section BB in FIG. 3; in fig. 5 is a view of B in FIG. k.

The vibratory mixer consists of a frame 1, elastic supports 2 and an oscillating part, made in the form of two cheeks 3, between which an inertial vibration exciter 4 is fixed, the shaft of which is driven into rotation from the electric motor 5 (Fig. 2) through an elastic coupling 6. On one side of the vibration exciter k on the cheeks 3 is fixed counterweight

7, on the other - mixing capacity

8. Inside the tank 8, the fixed screw guides 9 are fixedly mounted. A curvilinear false is fixed at the meeting point of the screw guides 9 10. Grinding bodies 9 in the form of rods 11 are freely located in the inner holes of the screw guides 9. The screw guides 9 can be provided with additional vertical transverse partitions 12, placed in their upper part (Fig.). The screw guides can be provided with a cylindrical guide 13 fixed in their inner bore, having a notch T in the middle part, mated with the false 10 and forming gaps with the ends of the container.

The vibratory mixer works as follows.

Vibrating material

the load is driven in a fluidized state and comes into intensive movement around the longitudinal axis of the tank 8 in the direction opposite to the rotation of the shaft of the vibration exciter, simultaneously shifting under the action of the opposing screw guides 9 from the ends of the tank 8 to its middle, and under the action of the curvilinear false 10 mother.-ui moves from ponerh

The capacity of the container to its center, where the loading level rises, then a part of the material flow is poured through the upper edges of the screw guides 9, and a part moves along the axis of the container through their internal holes, while the grinding bodies 11 are processed here.

When making screw guides 9 with partitions 12, the entire flow of loading material moving from the middle of the container 8 to its ends is guided through the internal openings of the screw guides 9, and is treated with grinding bodies 11. When the internal circular edges of the screw guides 9 are made with a cylindrical guide 13, having in its middle part mating with a false

10 notch, and with the mountaineers of the tank 8 - the gaps, there is a decrease in contact stresses between the grinding bodies

11, a gap is formed between the cylindrical guides 13 and the ends of the container 8.

Grinding bodies in the form of rods 11 in order to increase the intensity of processing and throughput by reducing the contact areas between them can have various notches on their surface, grooves, grooves, etc. In addition, a cylindrical guide .13 can be made perforated or in the form of two twisted tapes with a winding pitch equal to the pitch of the screw guides 9.

The use of the proposed vibromixer allows, in comparison with the known, to improve the quality of the prepared loose mixture due to the presence in the tank of grinding bodies made in the form of rods and freely located in the inner holes of the screw guides. Making helical guides with vertical transverse partitions allows for more directional movement of the loading material (only through the internal holes of the helical guides) and thereby improves the quality of the mixture being prepared. The presence of a cylindrical guide makes it possible, without compromising the mixing process, to increase the durability of the structure, since the contact stresses between grinding mills are reduced.
