Description

The invention relates to devices for mixing multicomponent mixtures and can be used mainly in the chemical and construction industries, as well as in other areas of the industrial industry where the production of this type of mixtures is necessary.

Currently, the use of multicomponent mixtures is one of the most relevant areas in various industries. The technology for the preparation of this type of mixture occupies not only one of the large segments of the market, but also is a promising base for developments in the field of technological equipment, in which particular importance is given to various types of devices for activating multicomponent media. The study of materials preparation processes today is a special branch of technological knowledge based on a combination of various physical, chemical and mechanical processes. An analysis of various works reveals that the greatest effect can be expected in the process of preparing multicomponent substances from the use of various vibration activators, when the components are subjected to the greatest number of actions per unit time.

So, for example, gravity mixers are known (Patent RU 148474 U1, 12/10/2014, B28C 5/22, B01F 11/00; Patent RU 148526 U1, 12/10/2014, B28C 5/22, B01F 11/00; Patent RU 148529 U1 , 10.12.2014, B28C 5/22, B01F 11/00; Patent RU 148597 U1, 12/10/2014, B01F 11/00; Patent RU 148598 U1, 12/10/2014, B01F 11/00; Patent RU 148599 U1, 10.12. 2014, B01F 11/00; Patent RU 148600 U1, 12/10/2014, B01F 9/00; Patent RU 148601 U1, 12/10/2014, B01F 11/00; Patent RU 164054 U1, 08/20/2016, B28C 5/00; Patent RU 164055 U1, 08/20/2016, В28С 5/00; Patent RU 164056 U1, 08/20/2016, В28С 5/04; Patent RU 164057 U1, 08/20/2016, В28С 5/16; Patent RU 164193 U1, 08/20/2016, B01F 11/00; Patent RU 164194 U1, 08.20.2016, B01F 11/00; Patent RU 164196 U1, 08.20.2016, B01F 11/00; Patent RU 164197 U1, 08.20.2016, B01F 11/00; Patent RU 164198 U1, 08.20.2016, B01F 11/00; Patent RU 164199 U1, 08.20.2016, B01F 11/00; Patent RU 164200 U1, 08.20.2016, B01F 11/00; Patent RU 164201 U1, 08.20.2016, B01F 11/00; Patent RU 164202 U1, 08.20.2016 B01F 11/00; Patent RU 164372 U1, 08.28.2016, B01F 11/00; Patent RU 164373 U1, 08.27.2016, B01F 11/00; Patent RU 164374 U1, 08.27.2016, B01F 11/00), containing a rotating drum with blades and a rotation drive installed in a support, a vibrator with kinematic excitation of oscillations and a rotation drive is cantilevered inside the drum, the vibrator is made with a housing mounted on a crankshaft so that its longitudinal axis is 5-10 ° with the drum axis, one end of the housing is coaxially connected to the bottom of the drum with an elastic element, and the second is supported by a spherical bearing on the connecting rod support of the crankshaft, on which the dis Balance is configured with a function of dynamic balancing of the unbalanced mass. In this case, the body of the vibrators are made in the form of metal thin-walled geometric bodies of various shapes.

The main drawback of the design of these mixers is the lack of necessary vibration protection of the design elements of the mixers due to the use of vibrators of an eccentric type.

Also known is a rotary vibration mixer with a ring magnetostrictive transducer (Patent RU 2318586 C2, 03/10/2008, B01F 11/00), comprising a mixing chamber, a rotor with a rotary drive made with blades, a vibrator, characterized in that the vibrator is made in the form of a radiating high-frequency vibrations of the pipe with the disk and is rigidly fixed in the middle of the mixing chamber. The main disadvantage of this mixer is the ineffective vibrational study of the mixture or its complete absence in the upper corner (“deaf”) zones of the mixing chamber.

Also known is a rotary mixer with a mechanical vibration exciter (Patent RU 2297274 C1, 04.20.2007, B01F 11/00), comprising a mixing chamber, a rotor with a rotary drive, made with blades, a vibrator made in the form of disk springs with rubber shock absorbers, and rigidly fixed in the middle of the mixing chamber. The vibrator has a crank mechanism, with the help of which the Belleville springs excite particle vibrations in the horizontal direction. In the mixer, it is possible to adjust the intensity of the vibration by changing the speed of the drive of the crank mechanism. The main disadvantages of this mixer include significant energy costs for the deformation of Belleville springs, a high percentage of wear of rubber shock absorbers, as well as insufficiently effective thixotropic destruction (dilution) of the material structure due to the excitation of vibrations of a strictly horizontal direction in the mixture.

The prior art also knows a rotary mixer with an electromechanical vibration exciter (Patent RU 2292943 C1, 02/10/2007, B01F 11/00) containing a mixing chamber, a rotor with a rotary drive made with blades, a vibrator made in the form of a bellows with a disk, is rigidly fixed in the middle of the mixing chamber. The vibrator has an electromagnet, with the help of which the bellows excites particle vibrations in the horizontal direction. The mixer has the ability to adjust the intensity of the vibration by changing the frequency of the alternating current supplied to the winding of the electromagnet.

The disadvantages of this device include the ineffective vibrational study of the mixture or its complete absence in the upper corner (“deaf”) zones of the mixing chamber due to the geometry of the bellows strictly cylindrical in shape, as well as inhomogeneous amplitude values of movements decreasing from the place of force acting to the fixation point of the bellows , in each individual section of the bellows, as a result of which the fluctuations from the place of force impact to the place of fixation of the bellows will have a damping nature, which dit reduce the effectiveness of vibratory impacts to the mixture in the bottom of the mixing chamber.

In the lower or lower and upper parts of the mixing chambers in the center, one or two vibrators are rigidly fixed, made in the bodies, with the excitation of vibration fields by means of the lower or lower and upper crank mechanisms. In this case, the vibrator bodies are made in the form of corrugated metal shells with different geometry of the bodies of revolution.

However, the main drawback of mixer designs is the lack of providing a combination of essential features of these devices with a new property, which consists in creating a vibration field or vibration fields corresponding to or individually corrugated contour of a three-dimensional body of revolution, which forms a complex truncated geometric cross section in the vertical plane at the points of the corrugations a figure consisting in the aggregate of equal semicircles, the extreme intersection points of which comfort vertices of a regular hexagon.

The technical result is to expand the arsenal of technical means and ensure the achievement of new properties by the claimed objects. That is, it is possible to create, over the entire volume of the mixer chamber, into the mixed components of the mixture, two vibrational fields of different frequency that correspond in aggregate to the shape of the corrugated contour of a three-dimensional body of revolution, which forms a complex truncated geometric figure in the vertical section along the corrugation vertex points from equal semicircles, the extreme intersection points of which form the vertices of a regular hexagon, with the simultaneous formation in two hours otnom range multidirectional oscillations completely exclude the presence of mixing chamber "deaf" zones, uniform amplitude distribution of vibratory impacts mixing chamber and qualitative process intensification mixing these components in general.

The technical result is achieved in that the vibration mixer comprising a mixing chamber with windows for loading and unloading materials, respectively, a rotor with a rotary drive made with blades, a vibrator made with a corrugated body and rigidly fixed in the middle of the mixing chamber, the vibrator is made with the excitation function of two identical in amplitude and vibration fields of different frequencies by means of the upper and lower crank mechanisms, inside the vibrator body in the center in a horizontal plane the disk is rigidly fixed with a cylindrical protrusion made with the possibility of insertion and fixing along the inner diameter of the spring installed with the free compression / expansion function in the cup, to the center of the upper inner part of which is a connecting rod with a drive from the upper crank mechanism, and to the center upper outer part - a pusher rigidly fixed with the other end to the inner upper part of the corrugated body and made with the function of exciting vibrations from the upper part of the vibrator body through Tun through the upper crank mechanism. The disk, the function of which is to create a uniform distribution throughout the volume of the mixing chamber of the vibration field from the upper to the lower part of the housing by creating uniform amplitude values of the displacements of each point of the outer generatrix of the corrugation of the housing, is configured to excite vibrations from the central part of the vibrator housing using four pushers , the upper part symmetrically fixed to the lower part of the disk, and the lower part connected to the node of the movable hinge of the connecting rod of the lower crank unnogo mechanism. Moreover, the vibrator body is made in the form of a metal corrugated shell, which is a corrugated thin-walled body of revolution, forming in the cross section of the vertical plane along the points of the corrugations vertices a complex truncated geometric figure consisting of a combination of equal semicircles, the extreme intersection points of which form the vertices of a regular hexagon, and made with the possibility of creating two-frequency vibrational fields, corresponding in total to the corrugated contour of the given body in shape tions, with multi-directional vibrations. The invention is illustrated by drawings: in FIG. 1 shows a diagram of a vibration mixer; in FIG. 2 is an enlarged diagram of a vibrator of a vibrating mixer.

The vibrating mixer comprises a mixing chamber 1 with loading windows 2 and unloading 3 materials, respectively, a rotor 4 with a rotation drive 5 made with blades 6, 7, a vibrator 8 made with a corrugated body 9 and rigidly fixed in the middle of the mixing chamber, the vibrator 8 is made with the excitation function of two vibrational fields of the same amplitude and different in frequency by means of the upper 10 and lower 11 crank mechanisms. Inside the case 9 of the vibrator 8, in the center in a horizontal plane, a disk 12 is rigidly fixed with a cylindrical protrusion 13 made with the possibility of insertion and fixing along the inner diameter of the spring 14, installed with the function of free compression / decompression in the glass 15, to the center of the upper inner part of which is rigidly fixed a connecting rod 16 with a drive from the top 10 of the crank mechanism, and to the center of the upper outer part is a pusher 17, rigidly fixed with the other end to the inner upper part of the corrugated body 9 and made with The function of excitation of vibrations from the upper part of the given case 9 of the vibrator 8 through the connecting rod 16 by means of the upper 10 of the crank mechanism. Moreover, the disk 12, the function of which is to create a uniform distribution throughout the entire chamber 1 of mixing the vibration field from the upper to the lower part of the housing 9 by creating uniform amplitude values of the displacements of each point of the outer generatrix of the corrugation of the housing 9, is configured to excite oscillations from the central part of the housing 9 vibrator 8 using four pushers 18, the upper part symmetrically attached to the lower part of the disk 12, and the lower part connected to the node of the movable hinge 19 of the connecting rod 20 of the lower 1 1 crank mechanism. Moreover, the housing 9 of the vibrator 8 is made in the form of a metal corrugated shell, which is a corrugated thin-walled body of revolution, forming in the cross section of the vertical plane along the points of the corrugation vertices a complex truncated geometric figure consisting of a combination of equal semicircles, the extreme intersection points of which form the vertices of a regular hexagon, and made with the possibility of creating two-frequency vibrational fields corresponding in the aggregate in shape to the corrugated contour of a given body eniya, with multi-directional vibrations.

The device works as follows: first, the components of the mixture, the composition of which is preliminarily selected, are loaded through the loading window 2 in layers into the mixing chamber 1 in the following sequence: sand is placed on the bottom of the mixer, then cement, after which crushed stone, last but not least, is supplied with the necessary load amount of water. Then the drives of the vibrator 8 and the drive 5 of the rotation of the rotor 4 with the blades 6, 7 are turned on. The drive 5 rotates the rotor 4 and the blades 6, 7, thereby mixing the prepared mixture. The pusher 17 through the cup 15 of the spring 14 and the connecting rod 16 by means of the upper crank mechanism 10 performs reciprocating movements, thereby exciting vibrations of the upper part of the housing 9, made in the form of a metal corrugated shell, which is a body of revolution, forming a vertical plane in cross section at the points of the corrugation vertices, a complex truncated geometric figure consisting in the aggregate of equal semicircles, the extreme intersection points of which form the vertices of a regular hexagon. Moreover, the disk 12, the function of which is to create a uniform distribution throughout the entire chamber 1 of mixing the vibration field from the upper to the lower part of the housing 9 by creating uniform amplitude values of the displacements of each point of the outer generatrix of the metal corrugated shell, excites vibrations of the central part of the housing 9 of the vibrator 8 by four pushers 18, the upper part symmetrically attached to the lower part of the disk 12, and the lower part connected to the node of the movable hinge 19 of the connecting rod 20 of the lower 11 cr voshipno-rod mechanism. After a specified time, the drive 5 of the rotor 4 and the drives of the crank mechanisms 10, 11 are turned off and the finished mixture is unloaded through the window 3 of the housing 1 of the mixer. In general, the device provides the possibility of creating, over the entire volume of the mixer chamber, onto the mixed components of the mixture, two vibrational fields of different frequency, corresponding in aggregate to the shape of the corrugated contour of a three-dimensional body of revolution, forming in the cross section of the vertical plane along the points of the corrugation vertices a complex truncated geometric figure consisting a set of equal semicircles, the extreme intersection points of which form the vertices of a regular hexagon, with the simultaneous formation a two-frequency range multidirectional oscillations completely exclude the presence of mixing chamber "deaf" zones, uniform amplitude distribution of vibratory impacts mixing chamber and qualitative process intensification mixing these components in general. This is due to the fact that, firstly, the vibrator body, made in the form of a metal corrugated shell, which is a corrugated thin-walled body of revolution, forming in the cross section of the vertical plane along the points of the corrugations vertices a complex truncated geometric figure, consisting of a combination of equal semicircles, extreme points the intersections of which form the vertices of a regular hexagon, and made with the possibility of creating two-frequency vibration fields corresponding in the aggregate in the form of corrugated On the one hand, this rotation body allows, on the one hand, realizing the possibility of creating a vibration mixture throughout the entire chamber of the mixer on the mixed components of the mixture that completely eliminates the presence of “dead” zones in the mixing chamber and, on the other hand, eliminates the vibration effect on the vibrator drive, to protect the bearing assemblies of the vibrator drive from the ingress of small particles of mixed materials, as well as to realize the possibility of complete transmission of the “useful” vibrational effect I'm on the material being processed. Secondly, the implementation in the design of the vibrator of two mechanisms, including: a pusher, a cup, a spring, a connecting rod of the upper crank mechanism and a disk with four pushers made with a movable hinge of the connecting rod of the lower crank mechanism, ensures the creation of uniform amplitude values of the displacements of each point external generatrix of the metal corrugated shell, thereby allowing for a uniform distribution of the vibration field in the mixing chamber, allows for the implementation of high-quality syphification of the mixing process of the components of the mixture during multi-frequency vibration, which consists in simultaneously influencing the mixture of vibrations of two or more frequencies and allowing, when superimposed on each other vibration curves, to increase the speed of the particles of the mixture, which in turn increases the efficiency of vibration. Multi-frequency vibration, based on the fact that each grain size corresponds to its own vibration frequency, can be considered as a means of influencing the largest number of grains, i.e. the intensity of multi-frequency vibrations is higher than the intensity of each of its constituent vibrations, thereby reducing the mixing cycle of the mixtures. And thirdly, the design of the mixer allows you to realize increased productivity, reduced energy costs for the mixing process, increased mobility and turbulization of the mixture, due to the uniform thixotropic destruction of the material structure in the entire space of the mixing chamber, which manifests itself in a decrease in the specific resistance to movement of the blade in the mixture compared to specific resistance to the movement of the blade of non-destroyed material. In this regard, the resistance to movement of the blades and the power consumption of the rotor rotation drive are reduced. At the same time, the effect of boiling of the mixture under the influence of oscillatory processes of the vibrator body, greater turbulization and more intensive circulation of the particles of the mixture is achieved, as a result of which the mixing time is reduced, the performance of the mixer is increased.
