Description

We offer a continuously operating agitator in the form of a vessel, in the middle of which a rotating shaft with central horizontal disks fixed to it is mounted.

Such agitators are known, made in the form of a vessel, inside of which a rotating shaft with centrally mounted discs is centrally mounted. However, these mixers do not provide rapid preparation of homogeneous suspensions with simultaneous grinding of solid particles or dissolution of the latter in the liquid phase.

To eliminate this drawback in the described mixer, in order to accelerate the displacement process, the lateral surface of the vessel has a stepped, increasing in diameter to the base form, and horizontal and horizontal discs, corresponding to the shape of the vessel, have an increasing diameter and are equipped with side partitions along the disk and nozzle openings formed by two adjacent partitions. The number of revolutions of the agitator shaft is recommended to be adjusted to 3000 per minute with the diameter of the lower disk of the agitator equal to 1 ml.

FIG. 1 depicts the proposed bashchalka in the section; in fig. - plan view (on a reduced scale).

The mixer consists of a vessel 1, inside of which, in bearings 2, a rotating shaft 5 is centrally mounted with horizontal disks 4 fixed on it, arranged in steps and having in the upper part side partitions 5 located along the chords of disk 4 and nozzle holes 6 formed by two adjacent partitions 5.

The components to be mixed are fed into the mixer through a telescopic inlet 7, whose height above the distribution disc can be adjusted by moving the inner tube 8 along its axis.

The fixation of the inner tube is achieved by an appropriate device 9.

When processing powdered substances to obtain a suspension, they are fed to the distribution disk 10 but the same telescopic. I enter. In this case, the liquid phase is fed through a perforated annular tube. The holes in the pipe are directed toward the frontal wall in such a way as to ensure continuous contact between the powder thrown by the distribution disc; and liquid. To remove the finished suspension but the periphery of the bottom of the agitator, there are holes 12. To eliminate settling of the suspension in the lower part of the apparatus, the lower disk is equipped with reflective blades. 13 The principle of operation of the agitator is as follows.

The components supplied to the upper disc 10 are last dropped to the frontal walls, the stack along which they are already in the form of a mixture onto the nozzle disc, the mixture in the form of jets is dropped to the armor pin 14 of the first stage. In this case, there is an effective dispersion of solid particles in suspension. Stack on the frontal wall of the first stage, the suspension falls on the second nozzle disk 4 and so on.

The treated slurry is removed from the agitator through outlet openings 12 located in the bottom of the vessel.

Subject invention

A continuously operating agitator is made in the form of a vessel within which a rotating shaft with central horizontal disks fixed on it is mounted centrally, characterized in that, with: The purpose of accelerating the mixing process, the lateral surface of the vessel has a step-like shape that increases in diameter to the base. horizontal disks, respectively, in the shape of a vessel, have a diameter increasing downward and are provided in the upper part with side partitions located along the chords of the disk and nozzle openings formed by two adjacent partitions.
