Abstract

The utility model relates to devices for grinding and mixing heterogeneous systems gas-liquid, liquid-liquid, liquid-solid particles by creating a relatively high shear stress, excitation of oscillations of the mixture being processed and a pulsating processing mode. EFFECT: increased mixing efficiency of heterogeneous liquid-liquid, liquid-gas systems. SUBSTANCE: vortex rotary-disk mixer contains loading and unloading nozzles, a drive, a fixed cylindrical body, in the volume of which perforated disks are rigidly fixed, between which there is a perforated disk similar in design, mounted on a rotating rotor. Teeth are located on the lower surface of the upper stationary disk, on the upper surface of the lower stationary disk and on both surfaces of the movable disk. The media are supplied separately to the space above the upper fixed disk through the nozzles, which are located tangentially in the cylindrical body, which leads to the creation of a rotational movement of the processed mixture and its mixing.

Description

The utility model relates to devices for grinding and mixing heterogeneous systems gas-liquid, liquid-liquid, liquid-solid particles by creating a relatively high shear stress, excitation of oscillations of the mixture being processed and a pulsating processing mode.

A device for grinding products is known, including enclosed in a housing coaxially located on a vertical shaft, alternating annular disks with cutting elements along the outer and inner diameters and washers alternating with these disks, as well as paddle loading and unloading impellers and a vacuum device connected to the upper part device, the upper part of the housing is separated from the grinding zone by means of a partition, and the vacuum device is located in the cavity formed by the mesh partition and the upper part of the housing, and the blades of the loading impeller are made in the form of a mesh partition and are installed at an angle to the vertical shaft.

The disadvantage of this device for grinding products is the complexity of the design and low productivity of the device due to the small area of grinding and processing environment.

The closest technical solution to the proposed utility model (prototype) is a rotary grinding mixer containing loading and unloading nozzles, a drive, a fixed cylindrical body, in the volume of which perforated disks are rigidly fixed, between which there is a perforated disk of a similar design, mounted on a rotating rotor, at the same time, on the lower surface of the upper fixed disk, on the upper surface of the lower fixed disk and on both surfaces of the movable disk, teeth are welded, inclined at an angle to the surface of the disk and containing slots on the movable and fixed disks.

The disadvantage of this rotary grinding mixer is the relatively low mixing efficiency of heterogeneous systems liquid-liquid, gas-liquid, liquid-solid particles.

The objective of the utility model is to create a new device - a vortex rotary-disk mixer with the following technical result: increasing the efficiency of mixing heterogeneous systems liquid-liquid, liquid-gas, liquid-solid particles.

This problem is solved by the fact that the vortex rotary-disk mixer contains loading and unloading nozzles, a drive, a fixed cylindrical body, in the volume of which perforated disks are rigidly fixed, between which there is a perforated disk of a similar design, mounted on a rotating rotor. Teeth are located on the lower surface of the upper stationary disk, on the upper surface of the lower stationary disk and on both surfaces of the movable disk. In this case, the supply of media is carried out separately into the pre-mixing zone through nozzles located tangentially in a cylindrical housing, which contributes to the creation of a rotational movement of the mixture being processed and its mixing.

The figure shows a vortex rotary disc mixer.

SUBSTANCE: vortex rotary-disk mixer contains loading pipes 1 and 2, unloading pipe 3, drive (not shown in the figure), fixed cylindrical body 4, in which perforated disks 5, 6 are rigidly fixed with perforated disk 7, similar in design, mounted on a rotating rotor 8, on the lower surface of the upper disk 5, on the upper surface of the lower disk 6 and on both surfaces of the movable disk 7, teeth 9 are welded, while the loading pipes 1 and 2 are located tangentially on the cylindrical body 4.

Vortex rotary-disk mixer works as follows.

Under the action of mass forces or artificially created pressure, the components of the processed heterogeneous medium are fed through tangential loading nozzles 1 and 2, twisting and mixing in the preliminary mixing zone (in the space between the upper fixed disk and the lid), then moves to the discharge nozzle 3. When moving through perforated disks 5, 6, 7, the heterogeneous medium is subjected to intense mechanical stress and the process of grinding and mixing takes place.

The main advantages of the proposed design of a vortex rotary-disk mixer include the following:

multifunctionality, which is determined by the possibility of grinding and mixing heterogeneous systems liquid-liquid, liquid-gas, liquid-solid particles;

high productivity and efficiency of the grinding and mixing process.

The utility model meets the criterion of "industrial applicability" and can be used in the chemical, food and paint industries for grinding and mixing heterogeneous gas-liquid, liquid-liquid systems.
