Description

Technical Field

[0001] This utility model relates to the field of pneumatic vibrator technology, specifically a pneumatic vibrator with adjustable strong vibration force. Background Technology

[0002] A vibrator is a device or equipment that generates periodic vibrations using mechanical, electromagnetic, pneumatic, or hydraulic methods.

[0003] Pneumatic vibrators, powered by compressed air, can operate safely in explosive, high-temperature, high-humidity, or dusty environments. They are essential for powder processing, which includes mineral, ceramic, and metal powders. New energy battery cathode material co-production lines, 3D printing or powder metallurgy recycling centers, and advanced ceramic-metal composite powder preparation workshops require simultaneous screening of mineral, ceramic, and metal powders. During powder processing, the vibrator needs to be fixed to a vibrating screen or filter frame. However, different materials have their own optimal fluidization frequencies; for example, minerals... The sieving frequency for industrial powders is 13–17Hz, for ceramic powders it is 25–50Hz, and for metal powders it is 25–42Hz. The fluidization frequency within this range allows the screen and the material to resonate, resulting in the fastest material flow and the cleanest sieving. When the vibrator frequency is 25–50Hz, ceramic powders and metal powders can be sieved. However, when sieving mineral powders, the powders are prone to compaction and the screen mesh is prone to clogging, which slows down the material flow and results in unclean sieving. Manual unclogging of the screen mesh is required, which affects the overall efficiency of material sieving.

[0004] To address this, a high-power adjustable pneumatic vibrator is proposed. Utility Model Content

Adjusting the rotation angle of the air inlet and air outlet adjustment components synchronously increases and decreases the air inlet flow rate and the exhaust flow rate of the air outlet, respectively.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0017] Reference Figures 1 to 7A high-power adjustable pneumatic vibrator includes a housing 1, a base 2, an air inlet 3, and an air outlet 4. It also includes an air inlet adjustment assembly 5, an air outlet adjustment assembly 6, a motor 7, and a transmission gear 8. The housing 1 is fixedly connected to the upper surface of the base 2. The upper surface of the housing 1 has the air inlet 3 and the air outlet 4, both of the same size and circular in shape, arranged symmetrically. The air inlet adjustment assembly 5 is threaded onto the air inlet 3, and the air outlet adjustment assembly 6 is threaded onto the air outlet 4. The motor 7 is fixed to the air inlet adjustment assembly 5, and the output end of the motor 7 is fixedly connected to the transmission gear 8. The transmission gear 8 is meshed between the air intake regulating component 5 and the air exhaust regulating component 6. The output end of the motor 7 drives the transmission gear 8 to rotate, and the transmission gear 8 drives the air intake regulating component 5 and the air exhaust regulating component 6 to rotate in the opposite direction to the rotation of the transmission gear 8. Adjusting the rotation angle of the air intake regulating component 5 and the air exhaust regulating component 6 synchronously increases and decreases the air intake flow of the air intake port 3 and the exhaust flow of the air exhaust port 4, respectively. Decreasing the air intake flow of the air intake port 3 and the exhaust flow of the air exhaust port 4 will reduce the vibration frequency of the pneumatic vibrator, and conversely, increasing the air intake flow and the exhaust flow will increase the vibration frequency of the pneumatic vibrator. The air intake regulating assembly 5 includes a first vent block 51, which is threadedly connected to the upper surface of the housing 1. A first connecting plate 53 is fixedly connected to the outer surface of the first vent block 51. A motor 7 is fixedly connected to the upper surface of the first connecting plate 53. A first toothed ring 56 is rotatably connected to the upper surface of the first vent block 51. A sliding block 59 is fixedly connected to the lower surface of the first toothed ring 56. A sliding groove 510 is formed on the upper surface of the first vent block 51. The lower end of the sliding block 59 is slidably connected inside the sliding groove 510. Both the sliding block 59 and the sliding groove 510 are trapezoidal to prevent the first toothed ring 56 from moving out of the first vent block 1. The upper surface of the vent block 51 slides down, and the first toothed ring 56 is engaged with one side of the transmission gear 8. The transmission gear 8 engages and drives the first toothed ring 56 to rotate. An arc-shaped groove 511 is provided on the upper surface of the first vent block 51. A bolt 57 is slidably connected inside the groove 511. The bolt 57 passes through the top of the first toothed ring 56. A nut 58 is threaded on the outer surface of the bolt 57. The nut 58 is tightly attached to the upper surface of the first toothed ring 56. When the first toothed ring 56 rotates, the nut 58 will slide inside the groove 511.

A vertical shaft 513 is fixedly connected to the upper surface of the horizontal bar 512. The vertical shaft 513 is fixed in the middle of the first ventilated block 51. A first stop block 514, a second stop block 519, a third stop block 520, and a fourth stop block 521 are slidably connected from top to bottom on the outer surface of the vertical shaft 513. Four placement slots 516 are opened inside the first ventilated block 51. The first stop block 514, the second stop block 519, the third stop block 520, and the fourth stop block 521 slide in the four placement slots 516 respectively.

The upper surfaces of the second block 519, the third block 520, and the fourth block 521 are all fixedly connected with limiting blocks 518. The upper end of the limiting block is slidably connected inside the limiting groove 517, so that when the first block 514 rotates at a certain angle, it will drive the second block 519 to rotate. When the second block 519 rotates at a certain angle, it will drive the third block 520 to rotate. And so on, the first block 514, the second block 519, the third block 520, and the fourth block 521 are opened or closed respectively to adjust the air intake flow of the air intake 3.

A second toothed ring 62 is slidably connected to the upper surface of the second vent block 61. A second connecting plate 611 is fixedly connected to the outer surface of the second toothed ring 62. The second connecting plate 611 is on the lower surface of the first connecting plate 53. The first connecting plate 53 and the second connecting plate 611 are threadedly connected to the interior of the second connecting plate 61 and the first vent block 51. The second toothed ring 62 is meshed with one side of the transmission gear 8. A pair of trapezoidal blocks 63 are fixedly connected to the lower surface of the second toothed ring 62. A trapezoidal groove 64 is provided on the upper surface of the second vent block 61. The lower ends of the pair of trapezoidal blocks 63 slide inside the trapezoidal groove 64 to prevent the second toothed ring 62 from slipping off the second vent block 61. A first sector plate 65 is fixedly connected to the inner side of the second toothed ring 62. A round rod 66 is fixedly connected to the middle of the first sector plate 65. The round rod 66 is fixed to the middle of the second toothed ring 62 and the second vent block 61. A second sector plate 651, a third sector plate 652, and a fourth sector plate 653 are slidably connected from top to bottom on the outer surface of the round rod 66. The first sector plate 65, the second sector plate 651, the third sector plate 652, and the fourth sector plate 653 have the same shape and size. The second sector plate 651 and the third sector plate 652... Both ends of the second and fourth sector plates 653 are fixedly connected to extension plates 68. The interior of the second vent block 61 has three hidden grooves 67. The extension plates 68 are slidably connected inside the hidden grooves 67, controlling the second sector plate 651, the third sector plate 652, and the fourth sector plate 653 to slide within the second vent block 61. The upper surfaces of the second sector plate 651, the third sector plate 652, and the fourth sector plate 653 all have circular grooves 610. The first sector plate 65, the second sector plate 651, and the third sector plate 652... The lower surface is fixedly connected with round blocks 69, the lower ends of which are slidably connected inside the round grooves 610. When the second gear ring 62 rotates, it drives the first sector plate 65 to rotate. When the first sector plate 65 rotates at a certain angle, it drives the second sector plate 651 to rotate. This process continues until the first sector plate 65, the second sector plate 651, the third sector plate 652, and the fourth sector plate 653 are opened and closed respectively, adjusting the exhaust flow of the air outlet 4. The upper surface of the base 2 is provided with a pair of first mounting holes 21, and one side of the base 2 is provided with a... For the second mounting hole 22, the pneumatic vibrator is fixed to the screen or filter frame through a pair of first mounting holes 21 and second mounting holes 22. The first gear ring 56 and the second gear ring 62 are driven to rotate synchronously through the transmission gear 8. The air inlet flow rate of the air inlet hole 3 and the exhaust flow rate of the air outlet hole 4 are adjusted synchronously. The vibration frequency of the pneumatic vibrator is adjusted for different materials to prevent the fluidization frequency of the material from being unequal to the vibration frequency of the vibrator, which would cause the material powder to be easily compacted and the screen to be easily clogged, thus slowing down the screen feeding and preventing the material screening efficiency from being affected.

[0019] Working principle: In use, insert the first vent block 51 and the second vent block 61 into the upper part of the housing 1. Insert the mounting bolt 530 into the interior of the first connecting plate 53, the second connecting plate 611, and the housing 1. Fix the first vent block 51 and the second vent block 61 to the upper surface of the housing 1. Fix the pneumatic vibrator to the screen or filter frame. Rotate the nut 58 to move it from top to bottom along the bolt 57, fixing the nut 58 to the upper surface of the first gear ring 56. Turn on the motor 7. The output end of the motor 7 drives the transmission gear 8 to rotate. The transmission gear 8 meshes and drives the first gear ring 56 and the second vent block 61 to rotate. The gear ring 62 rotates synchronously in the same direction. The rotation of the first gear ring 56 and the second gear ring 62 drives the first stop block 514 and the first sector plate 65 to rotate respectively. The rotation of the first stop block 514 opens or closes the first stop block 514, the second stop block 519, the third stop block 520 and the fourth stop block 521 in sequence, adjusting the air intake flow of the air inlet 3. The rotation of the first sector plate 65 opens or closes the second sector plate 651, the third sector plate 652 and the fourth sector plate 653 in sequence, adjusting the exhaust flow of the air outlet 4. The air flow of the air inlet 3 and the air outlet 4 are adjusted synchronously to control the vibration frequency of the pneumatic vibrator.
