Description

Technical Field

[0001] The invention relates to the technical field of acoustic resonance mixers, and in particular to a three-mass acoustic resonance mixer. Background Art

[0002] The acoustic resonance mixer utilizes the high-intensity vibration generated by the resonance of the mechanical system, and excites low-frequency and high-intensity sound waves in the multiphase flow through the high-intensity vibration. Under the stimulation of the sound waves and the system, the purpose of resonant mixing is achieved. The acoustic resonance mixer is generally divided into a two-mass acoustic resonance mixer and a three-mass acoustic resonance mixer.

[0003] The existing vibration mechanism uses 4 or 6 servo motors in parallel to drive the counterweight to vibrate. Since the four motors operate independently, the control logic is relatively complex. Four or six servo motors take up a lot of space and are expensive, so the product is less economical.

[0004] Both the two-mass acoustic resonance mixer and the three-mass acoustic resonance mixer utilize the resonance principle to amplify the exciting force, increase the acceleration during the mixing process, and reduce the driving power. Currently, most of the acoustic resonance mixers are two-mass acoustic resonance mixers, and three-mass acoustic resonance mixers are relatively rare.

[0005] Therefore, designing a three-mass acoustic resonance mixer with a simple control structure, low cost and easy operation is an urgent issue for researchers. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] A three-body acoustic resonance mixer comprises an excitation module, a load module, a resonance module and a frame, wherein the resonance module is mounted on the frame, the excitation module and the load module are both mounted on the resonance module, the excitation module is located between the resonance module and the load module, and the load module is fixedly connected to the frame; the excitation module comprises an excitation source, the excitation source comprises two vibration components, the vibration components are mounted on a first rotating power component, the vibration components are located on the same straight line and there is an angle between the vibration components, and the vibration components are connected through a second rotating power component.

[0037] When mixing, first, turn on the excitation module, and the two vibration components of the excitation module start working, such as Figure 5 As shown in the figure, since the vibration components are located on the same straight line and there is an angle θ, the exciting force F generated by the two vibration components 激振2 and F 激振2 The resultant force is F 激振 , thereby ensuring that there is no exciting force in the horizontal direction of the acoustic resonance mixer, improving the working stability of the mixer and reducing the working noise of the mixer; secondly, the first rotating power component provides angle control for the vibration component, and the second rotating power component controls the vibration component to generate exciting force, thereby ensuring efficient control of the acoustic resonance mixer and improving work efficiency; finally, the exciting module transmits the exciting force to the resonance module, and the resonance module transmits the exciting force to the load module, thereby realizing the mixing of the material in the material barrel placed on the load module.

[0038] Further, such as Figure 2 and Figure 4 As shown, the vibration component includes a mounting plate 1, which is mounted on the second rotating power component, an eccentric counterweight component is arranged on the outer side of the mounting plate 1, a slider 101 is arranged on the inner side of the mounting plate 1, the slider 101 is slidably arranged on a ring rail 102 and the ring rail 102 is fixed on a vibration frame, the mounting plates 1 are located on the same straight line and there is an angle between the mounting plates 1, the ring rail 102 is located on the same straight line and there is an angle between the ring rail 102, and the vibration frame is installed on the excitation module.

[0039] When the excitation module is turned on, the second rotating power component starts to output, such as Figure 2As shown, the mounting plate 1 is controlled to rotate, and the slider 101 on the mounting plate 1 reciprocates along the ring track 102. The eccentric counterweight assembly on the mounting plate 1 moves eccentrically driven by the mounting plate 1 to generate an exciting force. Since the mounting plates 1 on both sides of the vibration frame move in opposite directions, the exciting force in the horizontal direction is offset, and the exciting module outputs the exciting force in the vertical direction to ensure the working stability of the mixer.

[0040] Specifically, Figure 3 As shown, the second rotating power assembly includes a second servo motor 3, which is mounted on the vibration starting frame and located between the mounting plates 1, and worms 301 with opposite directions are arranged on both sides of the second servo motor 3, and the output end of the second servo motor 3 is connected to the worm 301 through a meshing gear set, and the worm 301 is meshed with a turbine 302 below the worm 301, and the turbine 302 is fixedly connected to the mounting plate 1 through a shaft sleeve 304 in a copper sleeve 303, and the copper sleeve 303 is mounted on the vibration starting frame.

[0041] When the mounting plate 1 needs to rotate, since the rotation direction needs to be opposite, the power is transmitted to two worms 301 in opposite directions through meshing gears at the output end of the second servo motor 3. The two worms 301 mesh with the turbine 302 to realize the rotation of the turbine 302. The turbine 302 drives the shaft sleeve 304 in the copper sleeve 303 to rotate, and the shaft sleeve 304 drives the mounting plate 1 to rotate, thereby achieving the purpose of the two mounting plates 1 rotating in opposite directions, and only one servo motor is needed for control, and the operation is simple and convenient.

[0042] Further, such as Figure 2 As shown, the eccentric counterweight assembly includes a driving gear 103, which is mounted on one end of the mounting plate 1 and is connected to the first rotating power assembly. The driving gear 103 is meshed with a driven gear 104 at the other end of the mounting plate 1. Eccentric counterweight blocks 105 are provided on the driving gear 103 and the driven gear 104, and the driven gear 104 corresponds to the slider 101.

[0043] When the second rotating power component is turned on, the first rotating power component is turned on, and the first rotating power component drives the driving gear 103 to rotate. The driving gear 103 controls the rotation of the driven gear 104 by meshing with the driven gear 104, thereby realizing the real-time rotation of the eccentric counterweight block 105 on the driving gear 103 and the driven gear 104, thereby realizing the eccentric rotation movement of the vibration component and generating an exciting force.

[0044] Specifically, the first rotating power assembly includes a first servo motor 2, which is mounted on the vibration frame. The output end of the first servo motor 2 is connected to a rotating shaft 201, which is fixedly connected to the driving gear 103 and movably mounted on the vibration frame.

[0045] When the driving gear 103 needs to rotate, the first servo motor 2 only needs to be turned on. The first servo motor 2 outputs power to the rotating shaft 201. The rotation of the rotating shaft 201 drives the driving gear 103 to rotate, thereby achieving angle control of the eccentric counterweight 105.

[0046] It is worth noting that, in this embodiment, in order to ensure that the movement of the rotating shaft 201 and the sleeve 304 does not interfere with each other, the rotating shaft 201 of the first rotating power component passes through the turbine 302, the sleeve 304 and the mounting plate 1, and the rotating shaft 201 is respectively connected to the turbine 302, the sleeve 304 and the mounting plate 1 through bearings, and the copper sleeve 303 is connected to the sleeve 304 through a bearing.

[0047] In this way, when the rotating shaft 201 rotates, due to the action of the bearing, the movement of the turbine 302, the shaft sleeve 304 and the mounting plate 1 will not be interfered with; when the turbine 302, the shaft sleeve 304 and the mounting plate 1 rotate, due to the action of the bearing, the movement of the rotating shaft 201 will not be interfered with; and the copper sleeve 303 is installed on the vibration starting frame, and the rotational movement of the rotating shaft 201 and the shaft sleeve 304 occurs in the copper sleeve 303. By setting the bearing, it can be ensured that the movement of the rotating shaft 201 and the shaft sleeve 304 does not affect the copper sleeve 303, and the copper sleeve 303 can support the components such as the rotating shaft 201 and the shaft sleeve 304, thereby ensuring the stability of the operation of the mixer.

[0048] Further, such as Figure 1 and Figure 6 As shown, the excitation module includes an excitation module mounting plate 4, such as Figure 7 As shown, the vibration starting frame of the centrifugal excitation mechanism is fixed below the excitation module mounting plate 4, and the first springs 401 are arranged on the upper and lower sides of the excitation module mounting plate 4. A first constraint guide rod 402 is arranged in the first spring 401 and passes through the excitation module mounting plate 4. One end of the first constraint guide rod 402 is fixedly connected to the resonance module and the other end of the first constraint guide rod 402 is fixedly connected to the end of the first spring 401 through a fixed end cover.

[0049] When mixing is required, the first servo motor 2 and the second servo motor 3 are turned on, and the excitation source generates an excitation force in the vertical direction. Since the vibration frame is inverted on the excitation module mounting plate 4, the generated excitation force is vertically transmitted to the excitation module mounting plate 4 upward, and the first spring 401 on the excitation module mounting plate 4 transmits the excitation force to the resonance module.

[0050] It is worth noting that in other embodiments of the present invention, the number of excitation sources can be set to other numbers as needed.

[0051] Further, such as Figure 1 and Figure 8 As shown, the load module includes an upper mass plate 5, and the upper and lower sides of the upper mass plate 5 are respectively connected to the resonance module and the frame through a second spring 501. An upper support plate frame and a lower support plate 503 are arranged on the upper mass plate 5. The upper support plate frame is connected to the upper mass plate 5 through a support rod and the upper support plate frame corresponds to the lower support plate 503. An upper support plate 502 is movably connected to the support rod of the upper support plate frame. A screw is arranged in a threaded hole at the upper end of the upper support plate frame, one end of the screw is connected to the upper support plate 502, and the other end of the screw is arranged with a knob; as shown Figure 1 and Fig. 9 As shown, the resonance module includes a lower mass plate 6, which is fixedly connected to the first spring 401 of the excitation module and the second spring 501 of the load module respectively, and third springs 601 are arranged on the upper and lower sides of the lower mass plate 6, and a second constraint guide rod 602 passing through the lower mass plate 6 is arranged in the third spring 601, one end of the second constraint guide rod 602 is fixedly connected to the frame and the other end of the second constraint guide rod 602 is fixedly connected to the end of the third spring 601 through a fixed end cover.

[0052] When the exciting force of the excitation module is transmitted to the lower mass plate 6 of the resonance module through the first spring, the lower mass plate 6 transmits the exciting force to the load module through the third spring 601, the upper mass plate 5 of the load module receives the exciting force and transmits it to the lower support plate 503, and the lower support plate 503 vibrates and mixes the material barrel.

[0053] It is worth mentioning that in this embodiment, before mixing, the material barrel is placed on the lower support plate 503, and a baffle is provided on the circumference of the lower support plate 503 to limit the horizontal direction of the material barrel. By rotating the knob, the screw pushes the upper support plate 502 down to limit the vertical direction of the material barrel, thereby ensuring the stability of the material barrel during mixing.

[0054] It is worth noting that, in this embodiment, in order to ensure the working stability of each spring, two restraining guide rods are provided, and a fixed end cover is provided at the end of the restraining lever to connect with the spring to ensure the working stability of the spring.

[0055] It is worth noting that, in the present embodiment, during the vibration process, the phase difference of the vibration curves of the load module and the resonance module is maintained at 180°, so the vibration exciting forces can offset each other.

[0056] Further, such as Figure 1 and Fig.10As shown, the frame includes a bottom plate 7 , which is connected to the lower mass plate 6 via a third spring 601 , and a vertical plate 701 is provided on the bottom plate 7 , which is connected to the upper mass plate 5 via a second spring 501 .

[0057] The bottom plate 7 on the frame supports the entire mixer, and the vertical plate 701 is connected to the second spring 501, thereby realizing the integrated structure of the entire mixer and ensuring the working stability.

[0058] It is worth noting that, in this embodiment, the motion differential equation of the entire mixer is:

[0059]

[0060] In the formula: M is the mass matrix; C is the damping matrix; K is the stiffness matrix; X is the displacement matrix; F is the system exciting force; is the acceleration matrix; is the velocity matrix.

[0061] It is worth noting that, in this embodiment, the excitation module is set to M1, the resonance module is set to M2, and the load module is set to M3, and the following is obtained: Fig.11 The kinetic model shown.

[0062] like Fig.11 As shown, the external simple harmonic exciting force Fsin acts on M1, forcing M1 to vibrate. The motion equation is:

[0063]

[0064] In the formula, and They are the motion accelerations of the excitation module, resonance module, and load module respectively; and are the movement speeds of the excitation module, resonance module, and load module respectively; x 1 With x 2 、x 3 are the actual displacements of the excitation module, resonance module, and load module respectively.

[0065] In the derivation process, the damping is ignored and the three natural frequencies of the system can be obtained, which can be obtained:

[0066] 0≤ω n1 ≤ω n2 ≤ω n3

[0067] In practical applications, the third-order natural frequency is selected as the system vibration frequency. Under this frequency, the movement directions of M2 and M3 are opposite, and the amplitude changes smoothly.

[0068] By transforming the formula, the system response to the stimulus is:

[0069]

[0070] In the formula, A N is the canonical vibration matrix of the system; B i is the amplitude of the mass; ψ i is the phase angle of the mass; β Ni is the amplification factor; ψ Ni is the phase angle. Therefore, from the system excitation force equation and the system's response to the excitation, it can be seen that the amplitude and phase of the three masses M1, M2 and M3 are related to the system's mass, spring stiffness, damping coefficient and the amplitude and frequency of the excitation force, and have nothing to do with the initial conditions.

[0071] By setting reasonable parameters, choosing reasonable spring stiffness and balancing the masses between each mass, the movement directions of M3 and M2 of the three-mass acoustic resonance mixer can be made opposite during operation, reducing the load of the entire mixer on the ground, reducing the vibration and noise on the foundation, and at the same time giving full play to the amplification effect of the three masses and reducing the driving power.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
