[0002] Cement slurry mixing equipment is a core piece of equipment used in concrete mixing plants, precast component production, and various grouting projects.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0041] Example: Figures 1 to 5As shown, the present invention proposes a dynamic balance compensation device for cement slurry stirring, including a support frame 1, a rotating shaft 2 rotatably installed on the support frame 1, and a motor 3 fixedly installed on the support frame 1. The motor 3 drives the rotating shaft 2 to rotate. The rotating shaft 2 is provided with a stirring blade 21. The stirring blade 21 is a pitched impeller or a propeller impeller. This type of impeller generates a strong axial flow, that is, a circulating flow from top to bottom or from bottom to top. This flow state can lift up the material that may be deposited at the bottom of the pool and make it participate in the circulation of the entire pool body, thereby preventing precipitation in the slurry mixing pool and improving the stirring effect.

[0042] Furthermore, the dynamic balance compensation device of this embodiment also includes a coupling 4, which connects the rotating shaft 2 and the output shaft of the motor 3. The coupling 4 can effectively transmit when the rotating shaft 2 and the output shaft of the motor 3 are eccentric. The coupling 4 includes a first connecting plate 41 fixedly mounted on the output shaft of the motor 3, a first slide groove 42 provided on the first connecting plate 41, a second connecting plate 43 slidably mounted on the first slide groove 42, a second slide groove 44 provided on the second connecting plate 43, and a connecting flange 45 slidably mounted on the second slide groove 44. When the rotating shaft 2 rotates eccentrically, it can drive the connecting flange 45 to rotate on the second connecting plate 43, and the second connecting plate 43 can rotate on the first connecting plate 41, thereby allowing the rotating shaft 2 to rotate eccentrically, so that the eccentric movement of the rotating shaft 2 does not affect the motor 3. The connecting flange 45 is fixedly connected to the rotating shaft 2 through the flange 46.

[0043] like Figures 1 to 4 As shown, the dynamic balancing compensation device of this embodiment also includes two groups of support components 5 installed inside the support frame 1. The support components 5 are rotatably connected to the rotating shaft 2 and axially position the rotating shaft 2. When the rotating shaft 2 is subjected to eccentric force, the support components 5 control the radial movement of the rotating shaft 2, which can prevent the vibration of the rotating shaft 2 on the entire support frame 1 when it rotates eccentrically, reduce the noise during equipment operation, and facilitate the detection of the eccentric direction and eccentric force generated by this eccentric motion, so as to facilitate compensation for the eccentric direction and enable the rotating shaft 2 to quickly return to a balanced state.

[0044] Furthermore, the support component 5 includes a support plate 51 installed inside the support frame 1, and the support plate 51 is rotatably connected to the rotating shaft 2 through a bearing 52. One of the support plates 51 is provided with a positioning member 53 for axially positioning the rotating shaft 2, thereby axially positioning the rotating shaft 2 to prevent the rotating shaft 2 from jumping in the up and down directions. A support module 54 is installed in the support frame 1 to support the planar support of the support plate 51. The support module 54 enables the support plate 51 to perform a certain floating movement on the plane on which it is located, so that the rotating shaft 2 can perform a certain degree of radial displacement.

[0045] Furthermore, the support module 54 includes a plurality of support tubes 541 rotatably installed inside the support frame 1, a sealing plate 542 sealed and slidably installed inside the support tube 541, and connecting rods 543 fixedly installed at both ends of the sealing plate 542. One of the connecting rods 543 is rotatably connected to the support plate 51, and a first elastic member 544 is fixedly installed between the other connecting rod 543 and the support tube 541. The first elastic member 544 is a spring. Under the action of the first elastic member 544, the distance between the sealing plate 542 and the rotating shaft 2 will be kept constant. When subjected to external force during the eccentric rotation of the rotating shaft 2, and the external force is sufficient to overcome the elastic force of the first elastic member 544, the support plate 51 will be offset, thereby causing the rotating shaft 2 to move radially.

[0046] It is worth noting that the two ends of the support cylinder 541 are connected by a pipe 545, and the pipe 545 and the support cylinder 541 are both filled with hydraulic medium. An electric control valve 546 is fixedly installed on the pipe 545. When the electric control valve 546 is in the open state, the hydraulic medium on both sides of the support cylinder 541 can flow with each other, and the hydraulic medium is a liquid that cannot be compressed under the working environment, so that the sealing plate 542 can move freely. When the electric control valve 546 is closed, the sealing plate 542 cannot move, and the position of the support plate 51 can be fixed to prevent the support plate 51 from moving. At this time, the position of the rotating shaft 2 will be fixed, and whether the rotating shaft 2 can move radially can be controlled according to usage requirements.

[0047] like Figures 6 to 10 As shown, the dynamic balance compensation device also includes a centrifugal compensation component 6, which includes a plurality of counterweights 61 installed on the rotating shaft 2, a wheelbase adjustment component 62 for controlling the wheelbase between the counterweight 61 and the rotating shaft 2, and a starting component 63 for starting the wheelbase adjustment component 62 according to whether the rotating shaft 2 is eccentric. In the initial state, the distances between the plurality of counterweights 61 and the rotating shaft 2 are equal, and the centrifugal force is related to the angular velocity, mass and rotation radius. At this time, the mass of the counterweight 61 is equal to the angular velocity and the rotation radius, and the forces applied by the plurality of counterweights 61 to the rotating shaft 2 are equal, so that the rotating shaft 2 will not be eccentric. If at this time the stirring blade 21 affects the rotation state of the rotating shaft 2, causing the rotating shaft 2 to generate eccentric force, which can be achieved by shrinking the counterweight block 61 in the direction of the eccentric force, that is, reducing the rotation radius of the counterweight block 61, reducing the centrifugal force of the counterweight block 61, and thus reducing the total eccentric force in this direction. If the centrifugal direction is located between the two counterweight blocks 61, the counterweight blocks 61 on both sides of the centrifugal force direction can be adjusted so that the resultant force in these two directions weakens the total centrifugal force in the centrifugal direction, so that the rotating shaft 2 is restored to a balanced state again. When eccentric movement occurs, it will affect the starting component 63 and adjust the wheelbase of the counterweight block 61.

[0048] Furthermore, the wheelbase adjustment assembly 62 includes an adjusting cylinder 621 fixedly mounted on the rotating shaft 2, a sealing block 622 sealed and slidably mounted inside the adjusting cylinder 621, and a round rod 623 fixedly mounted on the blocking block 622. The counterweight 61 is fixedly connected to the round rod 623. By moving the blocking block 622, the round rod 623 can be driven to move. The moving round rod 623 will drive the counterweight 61 to move, thereby adjusting the wheelbase of the counterweight 61. A driving cylinder 624 is fixedly mounted on the rotating shaft 2, and a sealing block 625 is sealed and slidably mounted inside the driving cylinder 624. A pull rod 626 is fixedly mounted on the sealing block 625. A second elastic member 627 is fixedly mounted between the pull rod 626 and the driving cylinder 624. Here, the second elastic member 627 is a spring member and is in a compressed state. When the elasticity of the second elastic member 627 is released, When the force can be released, it will drive the sealing block 625 to move upward. The adjusting cylinder 621 and the driving cylinder 624 are connected by a delivery pipe 628. The delivery pipe 628, the adjusting cylinder 621 and the driving cylinder 624 are all filled with hydraulic medium. When the sealing block 625 moves upward, the hydraulic medium will be attracted. At this time, the hydraulic medium inside the adjusting cylinder 621 can be sucked into the driving cylinder 624, thereby driving the counterweight block 61 to move, thereby reducing the rotation radius of the counterweight block 61 and thus reducing the centrifugal force of the counterweight block 61. A valve 629 is fixedly installed on the delivery pipe 628, and the starting component 63 controls the opening and closing of the valve 629. When the valve 629 is in the open state, the elastic force of the second elastic member 627 can be released. Conversely, when the valve 629 is closed, the elastic force of the second elastic member 627 cannot be released.

[0049] The valve 629 includes a valve body 6291 fixedly mounted on the delivery pipe 628 and a valve core 6292 slidably mounted in the valve body 6291 . The open or closed state of the valve body 6291 can be controlled by moving the valve core 6292 .

[0050] Furthermore, the starting assembly 63 includes a thin cylinder 631 fixedly mounted on the rotating shaft 2, a sealing body 632 slidably and sealingly mounted inside the thin cylinder 631, a starting rod 633 fixedly mounted on the sealing body 632 and fixedly connected to the valve core 6292, a thick cylinder 634 fixedly mounted on the rotating shaft 2 and having an inner diameter larger than the thin cylinder 631, a sealing plate 635 slidably and sealingly mounted inside the thick cylinder 634, a pressure rod 636 fixedly mounted on the sealing plate 635, a third elastic member 637 fixedly mounted between the pressure rod 636 and the thick cylinder 634, a roller 638 rotatably mounted on the pressure rod 636, a positioning ring 639 fixedly mounted in the support frame 1, and when the rotating shaft 2 moves eccentrically, it will drive the roller 638 to move radially so that the roller 638 can move closer to the positioning ring 63 9, and when the roller 638 contacts the positioning ring 639, it will drive the sealing plate 635 to move. The thin cylinder 631 and the thick cylinder 634 are connected by the connecting pipe 6310, and the inside of the side where the thin cylinder 631 and the thick cylinder 634 are connected to each other and the connecting pipe 6310 are filled with hydraulic medium. When the sealing plate 635 moves, the hydraulic medium will be squeezed into the inside of the thin cylinder 631, and then the sealing body 632 will be pushed to move, so that the valve core 6292 will move, so that the valve 629 can be opened, so that the rotation radius of the corresponding counterweight block 61 is changed, and because the inner diameter of the thick cylinder 634 is larger than that of the thin cylinder 631, a multiple distance relationship can be formed, which amplifies the stroke of the sealing plate 635 and makes the blocking state of the valve 629 more sensitive.

[0051] It should be noted that, through the setting of the above mechanism, the large eccentric force on the rotating shaft 2 can be effectively eliminated, so that the eccentric force on the rotating shaft 2 can be controlled within a certain range, ensuring the stability of the equipment operation, avoiding vibration interference, and reducing vibration noise during operation.

[0052] like Figure 11 and Figure 12 As shown, in this embodiment, a first reset component 7 for controlling the unified opening of multiple valves 629 is installed in the support frame 1. The first reset component 7 includes a lifting ring 71 slidably installed inside the support frame 1 and a first push rod motor 72 fixedly installed inside the support frame 1. The output shaft of the first push rod motor 72 is fixedly connected to the lifting ring 71. Multiple pressure rings 73 are slidably installed inside the support frame 1. A connecting rod 74 is rotatably installed between the pressure ring 73 and the lifting ring 71. A rolling body 75 is rotatably installed on the pressure rod. The rolling body 75 is located on one side of the pressure ring 73. Before starting the device each time, the position of the counterweight 61 needs to be reset. At this time, the valve 629 needs to be opened. The lifting ring 71 is driven to rise by the first push rod motor 72, and the multiple pressure rings 73 are driven to shrink synchronously by the connecting rod 74, so that the pressure ring 73 can drive the rolling body 75 to move, and then the pressure rod moves, so that the multiple valves 629 can be opened.

[0053] like Figure 6 As shown, in this embodiment, a second reset assembly 8 for uniformly controlling the wheelbase of the counterweight 61 is installed in the support frame 1. The second reset assembly 8 includes a second push rod motor 81 fixedly installed inside the support frame 1 and a pressure ring 82 slidably installed inside the support frame 1. The output shaft of the second push rod motor 81 is fixedly connected to the pressure ring 82. The second push rod motor 81 drives the pressure ring 82 to press down, which can drive the pull rod 626 to move downward in a unified manner, thereby uniformly adjusting the positions of multiple counterweights 61. Subsequently, the first push rod motor 72 drives the multiple pressure rings 73 to expand, so that the valve 629 can be closed, and the position of the counterweight 61 can be adjusted and fixed.

[0054] In this embodiment, when the rotating shaft 2 vibrates eccentrically due to attachment or wear of the stirring blade 21, the eccentric force forces the support plate 51 to produce radial displacement through the support module 54. At the same time, the roller 638 fixed on the rotating shaft 2 contacts the positioning ring 639 with the eccentric rotation, pushing the pressure rod 636 and thus moving the sealing plate 635 in the thick cylinder 634. The hydraulic medium enters the thin cylinder 631 through the connecting pipe 6310 to push the sealing body 632 and the starting rod 633, opening the valve 629. After the valve 629 is opened, the pre-compressed second elastic member 627 in the driving cylinder 624 is released, pulling the sealing block 625 upward, attracting the hydraulic medium in the adjusting cylinder 621, so that the sealing block 622 drives the round rod 623 and the counterweight block 61 to move inward, reducing the rotation radius of the counterweight block 61, thereby reducing the centrifugal force in the eccentric direction and restoring the dynamic balance of the rotating shaft 2.

[0055] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
