Description

Technical field

The utility model relates to the field of grinding and mixing bulk / liquid media and can be used as the main building block in the designs of disintegrators / activators for any power and productivity, which can be used as a highly efficient mill (grinding to nanoscale various materials regardless of their hardness), highly efficient mixer (allowing to obtain homogeneous mixtures of various substances and high-quality suspensions of almost immiscible liquids, such as water and oil), activator fi ble and chemical processes in various areas of industrial production to produce on an industrial scale of new types of building materials, paints, composite nanomaterials, food, perfumery composites.

State of the art

Known induction device for grinding solid materials, as well as mixing liquid and granular media, (utility model No. 53933 MPK V01A 13/08, 06/10/2006), containing a housing inside which an inductor is located, two cylindrical bushings forming an annular working area (RE), partially filled with ferromagnetic particles. A ferromagnetic core and a multiphase winding are located on a sleeve of a smaller diameter. The disadvantages of this device include inefficient mixing and grinding of components due to the inability to create a large amount of magnetic field induction in the annular working gap with the selected design of the inductor. In addition, this apparatus is difficult in design and has large specific energy costs.

Another induction device for mixing and grinding liquid and granular media is also known (“An intensifier of technological processes based on an activator with a vortex ferromagnetic layer”, publishing house “Technika”, 1975), which is known in the scientific and technical literature as an intensifier Longvinenko and which is used in this application as the closest solution is the prototype. The Longvinenko intensifier has a heavy cast case made of ferrous metal with an inductor located inside it, in the cavities of which there are multilayer electromagnetic coils wound with a copper bus, allowing a current density of only 2 A / cm ² and therefore having a sufficiently large ohmic resistance. This deprived the author of this apparatus of the opportunity to extend the length of the RE, and therefore he could not avoid:

a large flux of scattered magnetic fields;

overheating of the magnetic inductor;

a relatively low value of the magnetic field energy density in RE;

overall device performance degradation.

For cooling, the entire intensifier inductor together with the coils is placed in transformer oil, which is forcedly cooled by pumping it through a water jacket. The centrally located cylindrical RE is bounded by a sleeve and partially filled with ferromagnetic particles. The whole inductor of this intensifier is selected from 6-terminal-blocks cut from a stamp from transformer iron sheets. This led to the need to wind the electric coils located on the radial parts of the poles of the inductor, directly on its finished assembly, in fact, manually. The selected design of the inductor of the Longvinenko intensifier, in addition to the above disadvantages, made it much more expensive and complicated to manufacture, and also led to:

but. large waste of raw material;

b. increase material consumption:

at. installation difficulties;

d. the difficulties of cooling electromagnetic coils;

e. difficulties in the operational maintenance of the device as a whole;

Utility Model Essence

The objective of the proposed utility model, i.e. universal module of industrial disintegrators / activators "(UMPD / A) is:

1) to avoid all the shortcomings of the intensifier Longvinenko;

2) to be able to many times increase the efficiency of the processes occurring in RE UMPD / A, from which disintegrators / activators are assembled, by sequentially linking the modules into a single chain, thereby repeatedly increasing the length of the RE assembly;

3) a significant increase in the energy density of the magnetic field in the RE composed of UMPD / A disintegrators / activators;

4) increasing the efficiency of grinding various materials;

5) increasing the efficiency of mixing and activation of composites of various materials in various environments;

6) reduction in material consumption;

7) improving the conditions of assembly, operational maintenance and repair during operation of the device;

8) increasing the overall economic efficiency of disintegrators / activators composed of UMPD / A.

The proposed universal module of industrial disintegrators / activators "(UMPD / A), is an electromagnetic device that contains a prefabricated 6-pole inductor, allowing:

eliminate all the disadvantages inherent in the prototype;

to obtain high technical parameters of the proposed utility model with a significant reduction in its material consumption;

to significantly increase the efficiency of the processes occurring in the RE composed of separate UMPD / A disintegrators / activators due to n-fold elongation, with electromagnetic coils, centrally and parallel to the poles of the inductor located cylindrical RE partially filled with a large coercive force by ferromagnetic particles of the working fluid, limited by bushings with end grids, while the inductor consists of 6 separate blocks including one sixth of the hexagonal external magnetic circuit and a radial spoke-pole with Formation thereon an electromagnetic coil made from hollow copper tubes passing therethrough cooled transformer oil.

Description of the preferred embodiment

On a rack 1 (Fig. 1) a three-phase electromagnetic 6-pole inductor 2 is installed, made of 6 identical blocks. A radial spoke-pole 3 is also mounted on the rack 1, made in the form of a package of elements cut from soft magnetic transformer iron sheet with a thickness of δ = 0.27 mm and a high magnetic permeability, glued with electrotechnical varnish and polymerized by the appropriate technology in an oven at a temperature of 150 ° C.

Pos. Figure 4 shows one sixth of the hexagonal peripheral magnetic circuit of a three-phase electromagnetic 6-pole inductor 4, assembled from 6 separate blocks assembled, each of which is vertically assembled in the form of a package of horizontally arranged elements cut by a laser from a sheet of soft magnetic transformer iron with thickness δ = 0.27 mm with a large value of magnetic permeability, glued together with electrical varnish and polymerized by the appropriate technology in an oven at a temperature of 150 ° C.

On the radial part of each block, i.e. on the spoke-pole 3, electromagnetic double-layer coils 5 are placed, wound with copper tubes, which are cooled by transformer oil.

The main pipe 6 is installed on the axis of the device, separating the inductor from the area of the working zone (RE) and allowing the device to interface with the peripherals and modules with each other in the process chain. Tube 6 is made of thin-walled stainless steel with an external diameter equal to d = 100 mm.

The sleeve 7 provides the alignment of the working elements of the device relative to the magnetic poles of the inductor, and is made of stainless steel with a wall thickness of Δ ~ 3 mm A working zone (RE) is formed inside the sleeve 7 in the plane of the poles of the inductor, limited in length along the axis by two stainless steel grids 8, restricting the height of the working area of the device and preventing the flow of finished products from the elements 9 of the working fluid outside the working area.

The volume of the working zone is partially filled with elements 9 of the working fluid made of hard magnetic material with a high coercive force, for example, of electrical steel EH9K15M2, which significantly increases the density of magnetic energy in the working area. Elements 9 are made in the form of balls or cylinders of various diameters with different ratios of length to diameter, the geometric parameters of which are selected depending on the requirements of the technology.

In FIG. 2 shows a schematic universal module of an industrial disintegrator / activator, top view.

With a sleeve diameter of 6 equal to ~ 0.1 m and a working zone (RE) height of ~ 0.75 m, magnetic induction values in the RE were obtained up to ~ 10 ⁴ G, which corresponds to an energy density of ~ 4 10 ⁵ J in the core / m ³ .

The design of the inductor 2 is optimized to obtain a higher value of the magnetic field induction in the working area due to a significant reduction in the scattered fields and an increase in the ratio of the length of the RE to its diameter by more than seven times compared with the prototype device while reducing the total weight of the inductor with electric windings from copper tube.

One of the technical results of the proposed module, as well as the prototype device, is that the magnitude of electromagnetic induction and its frequency response lead to a preliminary decrease in the strength of the processed material, which helps to increase the efficiency of the dispersion of solid crystalline materials, reduce the energy costs of the process and the specific wear of the equipment .

Studies have shown that the effect of a high value of magnetic induction with a frequency of ~ 1 kHz leads to a significant weakening of the interaction forces in solid crystalline materials, for example, in rocks along cleavage planes and, consequently, to their more efficient dispersion, as well as the physicochemical activation obtained with particles.

The consumption of the inventive device compared with the consumption of the prototype device is lower, since the device has one working area. The design features of the claimed device greatly simplify the maintenance and repair compared to the intensifier Longvinenko, significantly reduce the consumption of materials and significantly increase efficiency compared to the prototype device.

The grinding of solid materials in the RE module occurs due to the “constrained impact”, as a result of which the grains of the obtained powders have very sharp edges, which helps to increase their physical and chemical activity.

This allows you to get more activity "binder" obtained from them during the "mixing" with a solution of alkali or soda and higher activity when used in powder chemistry. This characteristic also contributes to the activation of the process of obtaining suspensions from these powders. Due to the powerful turbulent movement of the mixture of liquids in the working area, the device can also be effectively used to obtain emulsions of practically immiscible liquids. The processes of grinding materials in the RE are superficial, therefore, these processes are all the more active, the higher the specific area of the initial product. Under the ongoing processes of material processing, no “clumping” of powders occurs; therefore, with an increase in the fineness of the powders, the process efficiency does not decrease, but rather increases.

Since there are no bearings or rubbing structural elements in the RE module, during operation of the device, in principle, jamming and stopping of equipment cannot occur. This equipment is low noise with low material consumption compared to other similar equipment for this purpose. Only the walls of the sleeve, which limits the working area, and the elements of the working substance, which are easily replaced during routine maintenance of the equipment, undergo wear. The durability is about 1000 hours when performing the sleeve RZ of steel X18H9T with a wall thickness of about 3 mm.
