Abstract

Use: for the preparation of mixtures of bulk and liquid materials. Essence: the mixer contains a conical case with a bottom made of elastic material to which a vibration exciter is attached on the outside, and on the inside a conical mixing element with an angle of inclination to its axis equal to 23-27i. 1il

Description

This invention relates to a technique for the preparation of bulk and liquid materials in various sectors of a national economy.

Apparatus for mixing bulk and liquid materials are known in which vibrators vibrate the vessel together with the materials to be mixed.

A device for preparing mortars, selected as a prototype, contains a conical hopper with discharge ports and a vibrator, and a vibrator oscillates a conical hopper together with materials to be mixed.

The disadvantage of this device lies in the fact that it does not provide high quality mixing, since it does not produce finely dispersed elements of the medium to the molecular, followed by good mixing.

The purpose of the invention is to intensify the mixing of materials by dispersing them, followed by mixing,

To do this, in the proposed device, the bottom of the body is made of elastic material, and the conical mixing element is with an angle of inclination of 23 to 27 ° forming to its axis.

Comparison of the proposed technical solutions with the prototype made it possible to establish compliance with the novelty criterion. In the study of other known technical solutions in this field of technology, the signs that distinguish the claimed device from the prototype were not identified, and therefore they provide the claimed technical solution with the criterion Significant differences.

Figure 1 presents the proposed mixer; figure 2 - section aa in figure 1.

The mixer consists of a conical body 1, a conical mixing element 2 with an angle of inclination to its axis equal to 23-27 °, the bottom 3 of the body, which is made in the form of a pliable membrane of elastic material attached to the narrow part of the truncated cone of the body 1.

Under the bottom 3 there is a box-type housing 4, in which shaft 5 is installed with unbalance 6. Shaft 5 through elastic

the coupling 7 is connected to the electric motor 8, which is mounted on the fixed bunker 1 by means of shock-absorbing suspensions 9. To remove the ready-mix from the bunker 1, it is provided with a valve 10 in the lower part at the membrane level.

The device works as follows.

The agitated medium is loaded into the housing 1 from above to a level above the top of the cone of the mixing element and the electric motor 8 is turned on, which rotates the shaft 5 with the unbalance 6. The unbalance 6 creates oscillatory movements of the bottom 3 and the conical mixer 2 resulting in the agitated medium forming compressions that break the surface tensions of liquid

components into the smallest granules; fine disintegration of solid elements of the medium to the molecular level occurs and simultaneous mixing of the granules of the various components relative to each other.
