Abstract

The utility model relates to the field of production of building materials, namely, devices for grinding, mixing and homogenizing materials. The rotary-pulsation installation for producing mixtures in liquid media contains dispensers, containers and product pipelines for introducing, respectively, the components of the mixture, if necessary, air and water. The installation includes a housing 1, to which two glasses 5 and 16 are rigidly fixed at both ends. On one side is a loading device that provides the supply of the mixture components to the working part. From the side of the loading device, a disk 6 is rigidly fixed to the stepped shaft, mounted perpendicular to the axis of rotation of the stepped shaft 3. Small 7 and large 8 rotor segments are rigidly fixed to the disk, oriented from the center to the same radius and the same angle. On the opposite side, a stator disk is mounted on the stepped shaft 3, on which small 11 and large 12 stator segments are rigidly fixed, forming ring gaps with rotor segments in which the components of the mixture are homogenized and ground. The purpose of creating a utility model was to intensify the process in the stagnant zones of the rotor segments. The problem is solved due to the fact that at the base of each tooth 9 of the rotor segments there are holes 10 conical in shape, oriented radially to the axis of rotation of the stepped rotor shaft, and the smaller base of the truncated cone is directed towards the stepped shaft. The technical result from the application of the proposed utility model is to intensify the process of homogenization, dispersion and grinding in the stagnant zones of the rotor segments, as well as the creation of additional mixture flows and the pressure difference of the mixture in the gap between the tooth surface and the surface of the conical hole and the pressure of the mixture passing through the conical hole . 4 ill.

Description

The proposed utility model relates to the field of production of building materials, namely, devices for grinding, mixing and homogenizing materials and can be used in various industries, in particular for the production of cellular concrete.

A known design of a rotary pulsation apparatus comprising a housing with covers and input and output nozzles with a set of coaxial cylinders with slots and a rotor made in the form of a disk on which radial blades and cylinders are placed coaxially mounted between the stator cylinders. Spiral grooves are made on the end surfaces of the rotor and stator cylinders [copyright certificate 709152 MPK B01F11 / 02, published January 15, 1980] A disadvantage of the apparatus is the low degree of dispersion of the mixture components in the base zone of the coaxial cylinders

Closest to the proposed design is the design of the rotor-pulsation installation containing, located on the same axis, segments of the rotor and stator, with slots made in them, located around the circumference. With the passage of the gaps between the segments of the rotor and stator, dispersion and homogenization of the components of the mixture are ensured [patent RU75348 IPC B28C 5/38 (2006.01), publ. 08/10/2008]. The disadvantages of this installation is the insufficient intensity of the processes of dispersion and homogenization of the components of the mixture.

The objective of the proposed utility model is to intensify the process of homogenization, dispersion and grinding in the stagnant zones of the small and large segments of the rotor.

The problem is solved due to the fact that on the large and small segments of the rotor, at the base of each tooth, a cone-shaped hole is made, oriented radially to the axis of rotation of the rotor shaft, moreover, with a smaller base directed towards the rotor shaft, which helps to separate the flow of the mixture from the walls of the hole and continuity flow within the walls of the hole, which intensifies the process of homogenization, dispersion and grinding in the stagnant zones of small and large segments of the rotor.

The technical result of the application of the proposed utility model is that it ensures the intensification of the process of homogenization, dispersion and grinding in the stagnant zones of the rotor segments, as well as the creation of additional mixture flows and the pressure difference of the mixture in the gap between the tooth surface and the surface of the conical hole and the pressure of the mixture passing through conical hole.

The rotary pulsation installation is illustrated by graphic materials.

The rotary-pulsation installation has a working part, consisting of a housing 1, to which a loading cup is rigidly attached 2. A stepped shaft 3 is located inside the housing. The following elements are rigidly fixed to the shaft: screw 4, used to pump the mixture components to the impeller 5, disk 6 on which small 7 and large 8 are fixed, segments of the rotor with teeth 9. In the segments of the rotor, at the base of each tooth, cone-shaped (in the form of a truncated cone) holes 10 are made (Fig. 4) oriented radially to the axis of rotation of the rotor shaft, and , with a smaller base, the truncated cone is directed towards the shaft 3. (Fig.2 and 3). Small 11 and large 12 stator segments are also fixed on the shaft. The stepped shaft 3 is supported by two rolling bearings 13, its shank 14 is rigidly fastened to the coupling 15. A drive cup 16 and an unloading pipe 17 are connected to the housing 1 of the installation. A receiving pipe 18 is installed in the loading cup 2. The stepped shaft 3 is rotated by electric drive (not shown in FIG.). To ensure the necessary pressure and porosity of the mixture in the loading cup 2, fittings 19 are provided for supplying compressed air. Air supply is provided by a compressor (not shown in FIG.).

Rotary pulsation installation for mixtures in liquid media works as follows.

The prepared components of the mixture are fed into the receiving pipe 18 of the loading cup 2 (figure 1). Then, using the screw 4 (Fig. 1), the components of the mixture are pre-mixed and pumped to the impeller 5 (Fig. 2), from which the mixture is discarded in the direction perpendicular to the rotating segments of the rotor (small 7 and large 8 and stator segments ( small 11 and large 12) (figure 2). With the passage of the gaps between the segments of the rotor 7 and 8 and the stator 11 and 12, homogenization, dispersion and grinding of the components of the mixture is ensured, and the presence of cone-shaped holes 10 (figure 2 and 3 and 4) the internal openings of which are smaller than the external ones (this helps to separate the flow from the walls of the hole and the flow remains uninterrupted within the walls of the hole), provides an intensification of the process of homogenization, dispersion and grinding in the stagnant zones of small and large segments of the rotor, and also ensures the creation of additional flows of the mixture and the difference in pressure of the mixture in the gap between the surface of the tooth 9 and the surface of the conical hole 10 made at the base of the tooth, as a result of which there is a phenomenon of cavitation, which will complement flax increases intensification process in stagnant areas of the rotor segments. In addition, it provides the necessary pressure of the resulting mixture, which allows for its transportation without the help of an additional device. At the end of the process, the finished mixture is thrown into the discharge pipe 17 and then discharged through the pipeline to the place of filling.

Thus, the use of a rotary-pulsation plant for the production of mixtures in liquid media makes it possible to improve the quality of dispersion and porization of the finished mixture, to increase the productivity of the plant, as well as to intensify its transportation.

Thus, the problem facing the utility model is solved.
