Description

11 The invention relates to devices for dispersing non-metallic materials in a liquid medium and can be used in the chemical, construction, mining, metallurgical and agricultural industries. The purpose of the invention is to intensify the process of dispersing materials. Figure 1 shows a dispersant, general view, section; Figure 2 is the same, top view with a poloBIN section. The disperser comprises a vertical cylindrical body 1 in which a cylindrical stator 2 and a hollow cylindrical rotor 3 are placed. Inside the rotor 3 there is a concentric grinding chamber 4 and an electro-hydraulic dispersing chamber 5. The step grinding chamber 4 is divided by horizontal grids 6 and is provided with grinding bodies 7, the size of the openings of the grids 6 and the size of grinding bodies 7 decreasing from top to bottom. Through the center of the electro-hydraulic dispersion chamber 5, a fixed Poland rod 8 passes, connected to the bottom of the grinding chamber 4 by means of a bearing unit. A system of positive electrodes 9 is mounted in the walls of the hollow rod 8, and inside the rod 8 a screw 10 is mounted, rigidly connected to the bottom of the grinding chamber 4 and being a negative electrode. In the upper part, the screw 10 is attached to the finished product pipe 11. The charging port 12 is attached to the cover of the disperser 13. The chambers 4 and 5 communicate through a passage 14 in the lower part of the hollow rod 8. Coils 15 are placed in the slots of the stator 2, creating a rotating magnetic field. . In the grooves of the rotor 3 placed short-closed tires 16. 7 Dispersant works as follows. . In the stator 2, to the coils 15 of which a voltage is applied from the network, a rotating magnetic field is created, causing the rotor 3 to rotate along with the grinding chamber 4. The components of the material to be processed together with water are continuously fed through the feed neck 12 to the first grinding stage in the grinding chamber 14, where they are crushed by grinding bodies 7 and through the grate 6 to the next grinding stage. At the bottom of the 4-step grinding chamber, the crushed material through the passage hole 14 in the hollow rod 8 enters the screw 10. The screw 10, rigidly connected to the bottom of the step-grinding chamber 4, rotates with it and transports the crushed material to the electro-hydraulic dispersion chamber 5. When a high voltage is applied between the positive electrodes 9 and the screw 10, which is the negative electrode, pulsed discharges occur. At the same time, shock waves, water flow, ultrasonic, resonant and cavitation processes occur, which intensify the process of dispersing materials. In addition, the advantages of the dispersant are that this design eliminates wear of the abrasive elements, increases the efficiency of the dispersion process due to the fact that the step grinding chamber and the electrohydraulic dispersion chamber are located in the running floor system. The disperser provides the ability to disperse a liquid-solid system, including hydrophobic materials in water.
