Abstract

The utility model relates to devices for grinding and mixing heterogeneous systems of gas-liquid, liquid-liquid, liquid-solid particles by exciting vibrations of the mixture being processed and creating a pumping effect. The rotary grinding mixer contains loading and unloading pipes, 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, 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 there are teeth, while the teeth located on the movable disk have longitudinal slots at the base with a height equal to half the height of the tooth and a length equal to 0.9 of the length of the tooth. The technical result is to increase the efficiency of mixing of heterogeneous liquid-liquid and gas-liquid systems.

Description

The utility model relates to devices for grinding and mixing heterogeneous systems of gas-liquid, liquid-liquid, liquid-solid particles by exciting vibrations of the mixture being processed and creating a pumping effect.

A device for grinding products is known, including enclosed in a housing and coaxially located on a vertical shaft, alternating ring-shaped disks with cutting elements along the outer and inner diameters and washers alternating with these disks, as well as bladed 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 zone of grinding and processing of the environment.

The closest technical solution to the proposed utility model (prototype) is a rotary grinding mixer containing loading and unloading pipes, 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, wherein 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 efficiency of mixing heterogeneous liquid-liquid and gas-liquid systems.

The technical problem of the utility model is the creation of a new device - a rotary grinding mixer with the achievement of the following technical result: increasing the efficiency of mixing heterogeneous liquid-liquid, gas-liquid systems.

The specified technical result is solved by the fact that 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 similar in design, mounted on a rotating rotor, on the lower surface of the upper fixed one. disk, on the upper surface of the lower fixed disk and on both surfaces of the movable disk there are teeth, while the teeth located on the movable disk have longitudinal slots at the base with a height equal to half the height of the tooth and a length equal to 0.9 of the length of the tooth.

The figure shows a rotary grinding mixer.

The rotary grinding mixer contains loading 1 and unloading 2 nozzles, a drive (not indicated in the figure), a stationary cylindrical body 3, in the volume of which perforated disks 4, 5 are rigidly fixed with a perforated disk 6 of a similar design, mounted on a rotating rotor 7, on the bottom the surface of the upper disk 4, on the upper surface of the lower disk 5 and on both surfaces of the movable disk 6, teeth 8 are welded, the teeth located on the movable disk have longitudinal slots 9 at the base with a height equal to half the height of the tooth and a length equal to 0.9 times the length tooth

The rotary grinding mixer works as follows.

Under the influence of mass forces, the heterogeneous medium being processed moves from the loading nozzle 1 to the unloading nozzle 2. When moving through the perforated disks 4, 5, 6, the heterogeneous medium is subjected to intense mechanical action, while the longitudinal slots 9 on the teeth 8 of the movable disk 6, when rotation, create additional turbulent flows of the processed medium, and the process of grinding and mixing occurs.

The main advantages of the proposed design of a rotary grinding mixer include the following:

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

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 systems of gas-liquid, liquid-liquid, liquid-solid particles.
