Description

The invention relates to the field of mixing various bulk materials to give them a homogeneous structure and can be used in the chemical, metallurgy, construction and other industries.

The aim of the invention is to intensify the mixing of materials.

In Fig, 1 shows the proposed vibration mixer; figure 2 is a section aa in figure 1.

The proposed mixer consists of a container 1 mounted using elastic elements 2 on a fixed base. In the central part of the container 1, a screw 3 is placed, which is connected at its ends to the small bases of the truncated cones 4 and 5. Spiral ribbons are wound around the forming surfaces of the cones 4 and 5

6 and 7. In the upper part of the container 1 there is a loading window 8. The bottom 9 of the container 1 is inclined and ends with a discharge window 10. Inside the container there is a mixed material 11. Under the bottom of the container is its drive, which includes an electric motor 12, an elastic coupling 13 and unbalances 14.

The proposed mixer operates as follows.

Through the loading window 8, components for mixing are fed into the container 1. Then the engine 12 is turned on and oscillatory movements are communicated to the container 1. Under the influence of vibration, the material 11 inside the container 1 will rotate. Under the action of the screw 3 inner layers

Material 11 is moved from the left end wall to the right, where it is captured by a tape spiral 7 of the end wall 5 and transported to the upper layers. At the left end wall 4, tape spirals 6 tighten the upper layers of material 11 to the screw and, thus, provide intensive volumetric circulation movement of the material. At the end of the mixing, the discharge window 10 is opened and with the exciter working, the material 11 is discharged from the container.

For quick and 100% unloading of material, the bottom 9 of the container 1 should be inclined towards the discharge window. In order to prevent the formation of stagnant zones at the discharge window 8, the screw 3 should be inclined at the same angle. In order to provide greater pressure of the material on the end walls in order to better and better capture material with spirals b and 7, truncated walls are located

cones 4 and 5, which with small bases pass into the screw 3,

Thus, the proposed technical solution makes it possible to significantly intensify the mixing process of a multicomponent material due to its volumetric circulation.
