Description

The invention relates to the chemical industry, in particular to devices for grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.

Known grinding and mixing unit containing a cylindrical body, grinding chambers with grinding bodies, a mixing chamber with working bodies, loading and unloading nozzles, while in the grinding chambers on the common shaft installed working bodies, a perforated partition between the grinding and mixing chambers, working bodies the mixer is made of a combination of blades and springs fixed by the ends on the blades. Grinding bodies are made in the form of cylindrical rollers, balls or tsilpebs.

A disadvantage of the known grinding and mixing unit is the low speed of rotation of the rotor due to the use of the mill in the form of cylindrical rollers, balls or tsilpebs and, therefore, low productivity of the device.

The closest technical solution to the proposed invention (prototype) is a centrifugal mill containing a cylindrical body, mounted in it fixed disk partitions and

vertically located working body, loading and unloading bins, drive, disk partitions made perforated and working body - in the form of rotating perforated disks located between the fixed disk partitions. [A.S. USSR No. 715134, cl. B 02 C 7/08, Centrifugal Mill / Voskanyan R.A .; Stated on 11.25.77 .; Posted on 02/20/1980.]

A disadvantage of the known centrifugal mill is the relatively low efficiency for grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.

The present invention solves the problem of increasing the efficiency and productivity of the process of grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.

This problem is solved due to the fact that in a rotary disintegrator-mixer containing a stationary cylindrical body, loading and unloading nozzles, a rotor rotating on bearings, on the shaft of which perforated disks are fixed, alternating with perforated disks fixed in the case, moreover, on the same the shaft is additionally equipped with a turbine mixer with blades directed at an angle of 45 ° to the axis of the shaft and a disk with rows of teeth concentrically located relative to the axis of the shaft, which alternate with rows of ntrichno disposed relative to the fixed tooth drive shaft axis fixed in the housing, wherein the clearances between the movable and fixed disks can be adjusted using shims.

Figure 1 shows a cross section of a rotary disintegrator-mixer.

Figure 2 - movable and stationary perforated discs.

Figure 3 is a section along aa in figure 1.

Figure 4 is a section along BB in figure 1.

The rotary disintegrator-mixer, in accordance with figure 1, contains a stationary cylindrical body 1, equipped with loading nozzles 2 and discharge nozzles 3, a rotor rotating on bearings, consisting of a shaft 4 with a sleeve 5 fixed to it by means of a key 6, on the sleeve 5 by keys 7 fixed turbine mixer 8, movable perforated discs 9 and movable disc 10 with rows of teeth concentrically arranged relative to the axis of the shaft 15. Fixed perforated discs 11 and stationary disc 12 with rows concentrically arranged the teeth 15 relative to the axis of the shaft are fixed in the housing 1 by means of a key 13. The movable perforated discs 9 and the stationary perforated discs 11 have concentric openings 14, the movable disc 10 has transport blades 16. The clearance between the working surfaces of the perforated discs 9 and 11, of the discs 10 and 12 depends on the thickness of the shims 17 alternating with the discs. The upper cover 19 with the thrust bearing 20 and the lower cover 21 with the thrust bearing 22 are attached to the housing 1 by means of bolts 18.

Rotary disintegrator-mixer operates as follows.

The turbine mixer 8, with blades directed at an angle of 45 °, creates an axial flow during rotation and the medium being processed moves from the loading nozzles 2 to the discharge nozzles 3. When moving through perforated disks 9 and 11, the product is subjected to intense mechanical stress and coarse and medium grinding and mixing, which is achieved by changing the size and geometry of the holes 14. By means of transport blades 16, the medium to be processed is directed through concentric s relative to the axis of the shaft of the teeth, is subjected to intense mechanical stress and the process of fine grinding and intensive mixing.

The intensity of the mechanical action is achieved by a relatively high rotor speed and the resulting highly turbulent movement of the medium being processed in the gaps between the movable perforated disks 9 and the stationary perforated disks 11 during coarse and medium grinding and mixing and due to the periodic change in the flow area between the movable disk 10 and a fixed disk 12 during fine grinding and mixing.

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

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

- the ability to control the intensity of the mechanical impact on the crushed and mixed medium by using shims of different thicknesses;

- the ability to control the passage speed of the crushed and mixed medium by changing the geometry of the concentric holes in the stationary perforated and movable perforated disks;

- high productivity and efficiency of the grinding and mixing process.

The invention meets the criterion of "industrial applicability" and can be used in the chemical industry for grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.
