Description

The invention relates to devices for mixing concrete mixture and can be used in the construction materials industry, in construction and other areas of the construction industry for the production of multicomponent mixtures. Currently, one of the urgent aspects of the development of the construction industry is monolithic construction, an important role in which is given to the preparation of concrete mixtures at the initial stage of production. Analysis of various sources makes it possible to detect the diversity of existing industrial concrete mixing machines implemented on the basis of machining in order to obtain high-quality concrete mixtures, i.e. getting them as uniform as possible in composition. The latter, in particular, makes it possible to single out the method of vibration processing of concrete mixtures, tested in time and in many scientific works, both in a single case and in conjunction with conventional mechanical activation.

The prior art various devices that are implemented on this basis.

For example, a rotary vibration mixer with a ring magnetostrictive transducer is known (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 emitting 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 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 concrete 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 This leads to a decrease in the efficiency of vibration effects on the concrete mixture in the lower part of the mixing chamber.

The closest analogs are vibration mixers (Patent RU 2494795 C1, 10/10/2013, B01F 11/00; Patent RU 2494796 C1, 10/10/2013, B01F 11/00; Patent RU 2494797 C1, 10/10/2013, B01F 11/00; Patent RU 2494798 C1, 10/10/2013, B01F 11/00; Patent RU 2494799 C1, 10/10/2013, B01F 11/00; Patent RU 2494800 C1, 10/10/2013, B01F 11/00; Patent RU 2494801 C1, 10/10/2013, B01F 11/00; Patent RU 2494802 C1, 10/10/2013, B01F 11/00; Patent RU 2494803 C1, 10/10/2013, B01F 11/00; Patent RU 2494804 C1, 10/10/2013, B01F 11/00; Patent RU 2494805 C1, 10.10.2013. B01F 11/00; Patent RU 2494862 C1, 10.10.2013, B01F 11/00; Patent RU 2495710 C1, 10.20.2013, B01F 11/00; Patent RU 2496562 C1, 10.27.2013, B01F 11 / 00; Patent RU 2496563 C1, 10.27.2013, B01F 11/00; Patent RU 2496564 C2, 10.27.2013, B01F 11/00; Patent RU 2496565 C2, 10.27.20 13, B01F 11/00; Patent RU 2496566 C2, 10.27.2013, B01F 11/00; Patent RU 2496567 C1, 10.27.2013, B01F 11/00; Patent RU 2496568 C1, 10.27.2013, B01F 11/00; Patent RU 2496569 C1, 10.27.2013, B01F 11/00; Patent RU 2497665 C1, 11/10/2013, B28C 5/16, B01F 11/00; Patent RU 2497666 C1, 11/10/2013, B28C 5/16, B01F 11/00; Patent RU 2497667 C2, 11/10/2013, B28C 5/16, B01F 11/00) containing a mixing chamber with loading and unloading windows for materials and a rotor with blades. 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 set of essential features of these devices with a new property, which consists in creating a vibration field or vibration fields corresponding to or individually shaped corrugated contour of a three-dimensional body of revolution, forming a truncated rhombus in a section of the vertical plane at the points of the corrugation vertices.

The technical result consists in expanding the arsenal of technical means and ensuring the achievement of new properties by the claimed objects. That is, the realization of the possibility of creating the entire volume of the mixer chamber onto the mixed components of the concrete mixture of three vibrational fields of different frequency, two of which correspond in aggregate, and the third separately, in the form of a corrugated contour of a three-dimensional body of revolution forming a vertical plane in section truncated rhombus with the possibility of creating the effect of superimposing data of vibration fields in the center of the mixing chamber, providing the possibility of creating multiple groups of aggregate three-frequency vibrational fields, each of which corresponds to a spiral-helical form with the formation of a dynamic effect of the imposition of these vibrational fields, and with the simultaneous formation of multidirectional vibrations in the three-frequency range, completely eliminating the presence of “dead” zones in the mixing chamber, additional vibrational effects on the mixed components, uniform amplitude distribution of each vibration field in the mixing chamber and high-quality intensification of the process mixing these components as a whole.

The technical result is achieved in that a vibration mixer comprising a mixing chamber with loading and unloading windows of materials, respectively, a rotor with a rotation drive, made with blades. In the center, in the lower and upper parts of the mixing chamber, two are rigidly fixed: the lower and upper, vibrators made in corrugated cases, with the excitation of vibrations by means of the lower, middle and upper crank mechanisms and with the function of creating the effect of superimposing vibration fields in the center of the mixing chamber from lower and upper vibrators, respectively. Moreover, inside the case of the lower vibrator, made with the excitation function of two vibration fields of the same amplitude and different frequency by means of the lower and middle crank mechanisms, a disk with a cylindrical protrusion made with the possibility of insertion and fixing on the inside is rigidly fixed in the center in the horizontal plane the diameter of the spring installed with the function of free compression / decompression in the cup, to the center of the upper inner part of which a connecting rod with a drive from the middle curve is rigidly fixed a crank mechanism, and to the center of the upper outer part there is a pusher rigidly fixed at the other end to the inner upper part of the lower vibrator housing and made with the function of exciting vibrations from the upper part of the lower vibrator housing through the connecting rod by means of a middle crank mechanism. Moreover, the disk of the lower vibrator, the function of which is to create a uniform distribution throughout the volume of the chamber mixing the vibration field from the upper to the lower part of the lower vibrator body by creating uniform amplitude values of the displacements of each point of the external generatrix of the body, is configured to excite vibrations of the central part of the lower vibrator body 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 rolling GERD lower connecting rod of the crank mechanism. At the same time, inside the upper vibrator case, in the center in the horizontal plane, a disk with a guide rack is rigidly fixed, the function of which is to create a stable directed translational movement of the rod from the translational pair formed by the guide rack of the upper part of the mixing chamber, the guide rack of the rotor blade drive and the upper vibrator rod, top a crank mechanism, and a cylindrical protrusion made with the possibility of insertion and fixing along the inner diameter of the spring, installed with the function of free compression / decompression in a cup, the rod is rigidly fixed to the center of the inner part, and the pusher is rigidly fixed to the center of the outer part, rigidly fixed with the other end to the inner part, which forms the smallest of corrugations, the upper vibrator body and made with the function of excitation of vibrations from the smallest of the corrugations of the upper vibrator body. Moreover, four protrusions are symmetrically fixed along the outer cylindrical part of the glass, the function of which is to transfer the reciprocating motion to the disk of the upper vibrator, made with the possibility of uniform distribution of the vibration field from the smallest of the corrugations of the upper body to the fixing point of the upper vibrator body by creating uniform amplitude values of the displacements of each points of the outer generatrix of the upper case, at the time of compression of the spring until it stops in rubber gaskets made with the function first collision mitigation projections with the disk of the upper vibrator. The cases of the vibrators are made in the form of metal corrugated shells, which are corrugated thin-walled bodies of revolution that form truncated rhombuses in the vertical plane section along the points of the corrugation vertices, and are configured to create three vibrational fields of the same amplitude and different frequency, two of which correspond together and the third - individually, in the form of a corrugated contour of these bodies of revolution, with multidirectional vibrations. At the same time, between the lower and upper vibrator bodies, a spring exciter is located in the center, made in the form of a spring group consisting of at least two different diameters of springs, which are fixed by the diameters of the depressions formed on the outer surface of the metal corrugated shells by the smallest group of lower and upper corrugations vibrators, and whose function is to create many groups of aggregate three-frequency vibration fields, each of which corresponds to a spiral-helical shape of the central x springs to form a spring vibration exciter dormant data aliasing vibration fields, and additional effects of vibration on the compounding components of the upper and lower housings vibrators respectively.

The invention is illustrated by drawings: figure 1 presents a diagram of a vibration mixer; figure 2 is an enlarged diagram of the lower vibrator of the vibration mixer; figure 3 is an enlarged diagram of the upper vibrator of the vibration mixer; figure 4 is an enlarged installation diagram of a spring exciter mounted between the upper and lower bodies of the vibrators.

The vibration mixer comprises a mixing chamber 1 with loading and unloading windows 3 of materials 3, respectively, a rotor 4 with a rotation drive 5, made with blades 6, 7, 8. In the lower and upper parts of the mixing chamber 1 in the center are rigidly fixed two: lower 9 and upper 10, vibrators made in corrugated bodies 11, 12, with excitation of vibrations by means of the lower 13, middle 14 and upper 15 crank mechanisms and with the function of creating the effect of imposing vibration fields in the center of the mixing chamber from the lower 9 and upper 10 vibrato moat respectively. Moreover, inside the housing 11 of the lower 9 vibrator, made with the excitation function of two vibrational fields of the same amplitude and different frequency by means of the lower 13 and middle 14 crank mechanisms, a disk 16 with a cylindrical protrusion 17 rigidly fixed in the center in a horizontal plane is made the ability to insert and fix along the inner diameter of the spring 18, installed with the function of free compression / decompression in the cup 19, to the center of the upper inner part of which the connecting rod 20 is rigidly fixed with a drive from the middle 14 of the crank mechanism, and to the center of the upper outer part - the pusher 21, rigidly fixed with the other end to the inner upper part of the housing 11 of the lower 9 vibrator and configured to excite vibrations from the upper part of the housing 11 of the lower 9 vibrator through the connecting rod 20 by means of the middle 14 crank mechanism. Moreover, the disk 16 of the lower 9 vibrator, 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 11 of the lower 9 vibrator by creating uniform amplitude values of the displacements of each point of the outer generatrix of the housing 11, is configured to excite vibrations of the central parts of the housing 11 of the lower 9 vibrator using four pushers 22, the upper part symmetrically attached to the lower part of the disk 16, and the lower part connected in a knot 23, the movable rod 24 hinge bottom 13 of the crank mechanism. At the same time, inside the case 12 of the upper 10 vibrator, a disk 25 with a guide rack 26 is rigidly fixed to the center in a horizontal plane, the function of which is to create a stable directed translational movement of the rod 27 from the translational pair formed by the guide rack 28 of the upper part of the mixing chamber 1, the guide rack 29 of the drive 5 rotation of the blades 6, 7, 8 and the rod 27 of the upper 10 vibrator, upper 15 of the crank mechanism, and a cylindrical protrusion 30 made with the possibility of insertion and fixing on the inside the smaller diameter of the spring 31, installed with the function of free compression / decompression in the cup 32, to the center of the inner part of which the rod 27 is rigidly fixed, and to the center of the outer part - the pusher 33, rigidly fixed at the other end to the inner part forming the smallest corrugation of the housing 12 top 10 of the vibrator and made with the function of exciting vibrations from the smallest of the corrugations of the housing 12 of the top 10 of the vibrator. Moreover, on the outer cylindrical part of the cup 32 four protrusions 34 are symmetrically fixed, the function of which is to transfer the reciprocating motion to the disk 25 of the upper vibrator 10, configured to uniformly distribute the vibration field from the smallest of the corrugations of the upper housing 12 to the fixing point of the housing 12 of the upper 10 vibrator by creating uniform amplitude values of the displacements of each point of the outer generatrix of the upper metal corrugated shell, at the time of compression of the spring 31 until it stops in rubber gaskets 35, made with the function of softening the collision of the protrusions 34 with the disk 25 of the upper 10 of the vibrator. The housings 11, 12 of the vibrators 9, 10 are made in the form of metal corrugated shells, which are corrugated thin-walled bodies of revolution that form truncated rhombuses in the vertical plane section along the points of the corrugation vertices, and are configured to create three vibration fields of the same amplitude and different frequency, two of which correspond in aggregate, and the third - separately, in the form of a corrugated contour of these bodies of revolution, with multidirectional vibrations. At the same time, between the bodies 11, 12 of the lower 9 and the upper 10 of the vibrators, a spring exciter 36 is located in the center, made in the form of a spring group consisting of at least two different diameters of springs, which are fixed by the diameters of the depressions formed on the outer surface of the metal corrugated shells by a group the smallest of the corrugations of the lower 9 and upper 10 vibrators, and the function of which is to create many groups of combined three-frequency vibration fields, each of which corresponds to a spiral-helical shape the central springs of the spring exciter 36 with the formation of the dynamization of the effect of the imposition of these vibration fields, and additional vibration effects on the mixed components from the upper 12 and lower 11 bodies 9, 10 of the vibrators, respectively.

The device operates as follows: first, the components of the concrete mixture, the composition of which is pre-selected, are loaded into the mixing chamber 1 through the loading window 2 in layers in the following sequence: sand is laid on the bottom of the mixer, then cement, after which the necessary crushed stone is lastly uniformly distributed over the entire load amount of water. Then the vibrator drives 9, 10 and the rotor drive 5 of the rotor 4 with the blades 6, 7, 8 are turned on. The drive 5 rotates the rotor 4 and the blades 6, 7, 8, thereby mixing the prepared mixture. The pusher 21 through the cup 19 of the spring 18 and the connecting rod 20 through the middle crank mechanism 14 makes a reciprocating motion, thereby exciting vibrations of the upper part of the housing 11 of the lower 9 of the vibrator. In this case, the disk 16 of the lower 9 vibrator excites vibrations of the central part of the housing 11 using four pushers 22, the upper part symmetrically attached to the lower part of the disk 16 of the lower 9 vibrator, and the lower part connected to the node of the movable hinge 23 of the connecting rod 24 of the lower 13 crank mechanism. Moreover, the pusher 33 through the cup 32 of the spring 31 and the rod 27 through the upper 15 crank mechanism performs reciprocating movements, thereby exciting vibrations of the body part 12, which forms the smallest corrugation of the metal corrugated shell of the upper 10 of the vibrator. At the same time, when the spring 31 is compressed into the rubber pads 35 of the disk 25 of the upper 10 vibrator, the protrusions 34 transmit reciprocating motion to the disk 25, which thereby additionally excites vibrations of the middle part of the housing 12 and creates a uniform distribution of the amplitude values of the displacements of each point of the external generatrix corrugated metal shell of the upper 10 vibrator. Moreover, the spring exciter 36, located in the center between the bodies 11, 12 of the lower 9 and the upper 10 of the vibrators, through a group of springs creates additional vibrational effects on the mixed components from the upper 12 and lower 11 of the vibrator bodies 9, 10, respectively. After a predetermined time, the drive 5 of the rotor 4 and the drives of the crank mechanisms 13, 14, 15 are turned off and the finished concrete mixture is unloaded through the window 3 of the mixer housing 1.

In general, the device provides the possibility of creating the entire volume of the mixer chamber for the mixed components of the concrete mixture of three different vibrational fields of frequency, two of which correspond in aggregate, and the third - individually, in the form of a corrugated contour of a three-dimensional body of revolution, forming a vertical plane in section truncated rhombus at the points of the corrugation vertices, with the simultaneous possibility of creating the effect of superimposing data of vibration fields in the center of the mixing chamber, making it possible many groups of combined three-frequency vibrational fields, each of which corresponds to a spiral-helical form with the formation of a dynamic effect of the imposition of these vibrational fields and with the simultaneous formation of multidirectional vibrations in the three-frequency range, completely eliminating the presence of “dead” zones in the mixing chamber, additional vibrational effects on the mixed components, a uniform amplitude distribution of each vibration field in the mixing chamber and high-quality intensification of ECCA mixing these components in general. This is due to the fact that, firstly, the cases of the vibrators are made in the form of metal corrugated shells, which are corrugated thin-walled bodies of revolution that form truncated rhombuses in the vertical plane section along the points of the corrugation vertices, and are made with the possibility of creating three identical in amplitude and different according to the frequency of vibration fields, two of which correspond in aggregate, and the third - individually, in the form of a corrugated contour of these bodies of revolution, with multidirectional vibrations, allow, with on the one hand, to realize the possibility of creating, over the entire volume of the mixer chamber, the vibrational effects on the mixed components of the concrete mixture that completely exclude the presence of “dead” zones in the mixing chamber, and on the other hand, eliminate the vibration effects on the vibrator drives, maximally protect the bearing assemblies of the vibrator drive from being hit they contain small particles of mixed materials, as well as realize the possibility of the complete transfer of “beneficial” vibrational effects to the processed material. Secondly, the implementation of the design of the mixer of two vibrators, between which a spring exciter is installed in the center and which include disk structural elements of the middle parts of the vibrators and pushers made with the possibility of exciting vibrations of the vibrator bodies from the smallest of corrugations, provides the possibility of creating a data overlay effect vibration fields in the center of the mixing chamber with the simultaneous formation of multidirectional oscillations in the three-frequency range and creating the possibility of by means of a spring vibration exciter of many groups of combined three-frequency vibration fields, each of which corresponds to the spiral-helical shape of the central spring of the spring exciter with the formation of a dynamic effect of the imposition of these vibration fields, and additional vibration effects on the mixed components from the upper and lower cases of the vibrators, respectively, of uniform amplitude values of displacements each point of the outer generatrix of the metal corrugated shells, thereby allowing homogeneous distribution of the vibration field in the mixing chamber, allows for the qualitative intensification of the process of mixing the components of the mixture during multi-frequency vibrations, which consists in simultaneously affecting the concrete mixture with 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, improves vibration efficiency. 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 concrete mixtures. And thirdly, the design of the mixer allows one to realize an increase in productivity, lower energy consumption for the mixing process, increased mobility and turbulization of the mixture due to uniform thixotropic destruction of the material structure in the entire space of the mixing chamber, which is manifested in a decrease in the specific resistance to movement of the blade in the concrete mixture compared with 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 mixer productivity is increased.
