Description

Technical Field

[0001] This application relates to the field of centrifuge drive connection technology, and in particular to a high-efficiency driven calcium carbonate dehydration centrifuge. Background Technology

[0002] Dehydration of calcium carbonate is a crucial step in industrial production. Centrifuges, as key dehydration equipment, directly impact dehydration efficiency and equipment stability through the performance of their transmission system. Traditional centrifuges typically use rigid couplings or ordinary flexible couplings to connect the motor and main shaft, which have the following technical drawbacks: rigid connections are prone to alignment errors at high speeds, leading to increased vibration and bearing wear; the buffer elements of ordinary flexible couplings are prone to failure under frequent start-stop cycles and load changes, especially when the calcium carbonate slurry concentration fluctuates, causing torque shocks to be directly transmitted to the transmission system; and traditional couplings require complete disassembly, resulting in long maintenance cycles and impacting production continuity.

[0003] Therefore, this application provides a high-efficiency driven calcium carbonate dehydration centrifuge. Summary of the Invention

[0004] The purpose of this application is to solve at least one technical problem raised in the background art.

[0005] This application provides a high-efficiency driven calcium carbonate dehydration centrifuge, comprising: an active connector and a driven connector. The active connector is coaxially fixed to the centrifuge main shaft, and the driven connector is coaxially connected to the motor main shaft. The active connector includes an active assembly cylinder, an active limiting disc fixedly installed on the inner wall of the active assembly cylinder, and a bushing rotatably installed on the left end of the active assembly cylinder via a bearing. The driven connector includes a driven assembly cylinder and a driven limiting disc fixedly installed on the inner wall of the driven assembly cylinder. The opposing surfaces of the active limiting disc and the driven limiting disc are each provided with a first semi-circular groove, and the opposing surfaces of the active assembly cylinder and the driven assembly cylinder are each provided with a second semi-circular groove. The first semi-circular groove and the second semi-circular groove form an integral circular groove, and an elastic buffer plug is inserted into the inner wall of the circular groove.

[0006] Preferably, the elastic buffer plug comprises an inner layer and an outer layer, the inner layer being made of a steel cylindrical rod and the outer layer being made of a polyurethane composite material.

[0007] By adopting the above technical solution, the active connector is coaxially fixed to the centrifuge main shaft, and the driven connector is coaxially connected to the motor main shaft. Then, an elastic buffer plug is inserted into the circular groove. This design ensures transmission alignment through the precise docking of the semi-circular groove, reducing vibration deviation during high-speed operation. When the centrifuge starts or the load fluctuates, the outer layer made of polyurethane composite material absorbs torque impact, avoiding motor overload caused by rigid transmission, while the inner layer of steel cylindrical rod prevents material deformation and ensures long-term stability. This can significantly reduce the impact of changes in calcium carbonate slurry concentration on the transmission system and extend the equipment life.

[0008] Preferably, the active assembly cylinder has an annular sealing boss on the right side and a sealing groove adapted to the annular sealing boss on the left side. A sealing ring is provided in the sealing groove, and the annular sealing boss, the sealing ring and the sealing groove cooperate to form a labyrinth-type sealing pair.

[0009] By adopting the above technical solution, the annular sealing boss, sealing ring and sealing groove cooperate to form a labyrinth sealing pair. Through multi-level tortuous paths, corrosive media and fine particles are blocked, the sealing ring enhances the initial sealing performance, and prevents moisture and chemical substances from seeping in during the calcium carbonate dehydration process.

[0010] Preferably, the left end of the active connector is provided with an elastic buffer mechanism, which includes a metal ring, a friction ring, a disc spring and a pressure ring sequentially sleeved on the surface of the bushing from right to left. A sleeve with a flange is fixedly installed on the surface of the bushing, and four sets of cylinders are fixedly installed in a circumferential array on the right end of the sleeve. The cylinders are supplied with air through an external air slip ring.

[0011] Preferably, the metal ring is made of spring steel with a hard chrome plating, the friction ring is made of copper-based powder metallurgy, and the pressure ring is provided with a pressure equalization groove to ensure uniform pressure distribution.

[0012] By adopting the above technical solution, the cylinder provides thrust and adjusts the clamping force of the disc spring to ensure stable contact between the friction ring and the metal ring. When the centrifuge starts, the cylinder extends slightly. At this time, the friction between the friction ring and the metal ring is small, and the friction ring will rotate on the metal ring. As the cylinder extends, the friction ring and the metal ring are in stable contact, and the increased friction can prevent the friction ring from rotating, thus driving the centrifuge to rotate smoothly. Therefore, the elastic buffer plunger can be protected to avoid overload.

[0013] Preferably, the left end of the active assembly cylinder is fixedly installed with limit blocks in a circumferential array, the inner ring surface of the metal ring is provided with a groove that matches the limit blocks, the left end of the limit blocks is fixedly installed with a stop block, and the inner ring surfaces of the friction ring, the butterfly spring and the pressure ring are all in contact with the surface of the stop block.

[0014] By adopting the above technical solution, after the slot on the metal ring is engaged with the limiting block, the metal ring can be limited to prevent it from rotating. The stop block can drive the friction ring, the disc spring and the pressure ring to be on the same central axis to prevent misalignment.

[0015] Preferably, the surfaces of the active connector and the driven connector are provided with a locking mechanism. The locking mechanism includes a mounting ring sleeved on the surface of the active assembly cylinder, four roller seats fixedly mounted in a circumferential array on the inner ring surface of the mounting ring, four mounting grooves opened in a circumferential array on the outer surface of the active assembly cylinder, rollers provided on the inner wall of the roller seats, clamping plates rotatably mounted on the inner wall of the mounting grooves, a clamping plate fixedly mounted on the outer surface of the driven assembly cylinder, and an elastic reset component provided on the surface of the active assembly cylinder. The end of the clamping plate near the roller is provided with a flat surface and a sloped surface, respectively.

[0016] Preferably, the elastic reset component includes a baffle fixedly installed on the outer surface of the active assembly cylinder, four guide holes arranged in a circumferential array on the surface of the baffle, a guide rod slidably fitted on the inner wall of the guide hole, and a reset spring sleeved on the surface of the guide rod, wherein one end of the guide rod is fixedly connected to the left end of the mounting ring.

[0017] Preferably, a positioning block is fixedly installed at the other end of the guide rod, and the two ends of the return spring abut against the opposite surfaces of the retaining plate and the mounting ring, respectively.

[0018] By adopting the above technical solution, after the active connector and the driven connector are connected, the return spring can drive the mounting ring to move to the right, thereby driving the roller on the roller seat to move along the slope of the clamping plate to the plane. At this time, the clamping plate can be driven to rotate and clamp the end face of the clamping plate, thus completing the rapid installation of the active connector and the driven connector. When the mounting ring is pulled to the left, the guide rod will slide along the inner wall of the guide hole to guide the roller seat. At this time, the roller will move along the plane of the clamping plate to the slope, thereby driving the clamping plate to rotate and disengage from the clamping plate to achieve rapid separation.

[0019] Preferably, an operating ring is rotatably mounted on the outer surface of the mounting ring, and four locking blocks are fixedly mounted in a circumferential array on the inner wall of the operating ring. The surface of the baffle is provided with a through groove for the locking blocks to pass through, and the surface of the operating ring is provided with anti-slip texture.

[0020] By adopting the above technical solution, when the operating ring is pulled to the left, the mounting ring can be moved synchronously. When the clamping plate rotates and disengages from the clamping plate, the locking block will move along the through groove to the left side of the baffle. Then, rotating the operating ring can drive the locking block to move out of the through groove. The reset force of the reset spring can drive the locking block to contact the baffle, thereby limiting the operating ring and preventing it from resetting. When it is necessary to assemble the active connector and the driven connector, rotating the operating ring will drive the locking block into the through groove, thereby driving the operating ring to move to the right and drive the clamping plate to rotate.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The high-efficiency driven calcium carbonate dehydration centrifuge described in this application effectively reduces vibration deviation during high-speed operation through a composite structure of circular grooves on the active and driven connectors combined with elastic buffer plugs, ensuring transmission alignment. The polyurethane outer layer absorbs torque impact, preventing motor overload, and the steel inner layer prevents material deformation, significantly reducing the impact of calcium carbonate slurry concentration fluctuations on the transmission system and extending equipment life.

[0023] 2. The high-efficiency driven calcium carbonate dehydration centrifuge described in this application has an elastic buffer mechanism that adjusts the clamping force of the disc spring through a cylinder to achieve progressive contact between the friction ring and the metal ring. When starting, the cylinder extends slightly, and the friction ring can slide to buffer the impact. After stable operation, the friction force increases to ensure smooth transmission and protect the elastic buffer piston from overload damage.

[0024] 3. The high-efficiency driven calcium carbonate dehydration centrifuge described in this application has a locking mechanism that uses a roller and clamping plate linkage design. The reset spring drives the installation ring to move, so that the roller slides along the inclined surface of the clamping plate to the plane, realizing quick clamping. Separation can be achieved by reversing the operation, which simplifies the disassembly and assembly process, avoids the overall disassembly of traditional couplings, significantly shortens maintenance time, and improves production continuity.

[0042] The following combination Figures 1 to 10 This application will be described in further detail below.

[0043] Example 1

[0044] Please refer to the following carefully. Figures 1 to 7A high-efficiency driven calcium carbonate dehydration centrifuge includes: an active connector 100 and a driven connector 200. The active connector 100 is coaxially fixed to the main shaft of a centrifuge 300, and the driven connector 200 is coaxially connected to the main shaft of a motor 400. The active connector 100 includes an active assembly cylinder 101, an active limiting disc 102 fixedly installed on the inner wall of the active assembly cylinder 101, and a bushing 103 rotatably installed on the left end of the active assembly cylinder 101 via a bearing. The driven connector 200 includes a driven assembly cylinder 201, a fixed... A driven limiting plate 202 is installed on the inner wall of the driven assembly cylinder 201. The opposite surfaces of the driven limiting plate 102 and the driven limiting plate 202 are provided with a first semi-circular groove 500. The opposite surfaces of the driven assembly cylinder 101 and the driven assembly cylinder 201 are provided with a second semi-circular groove 501. The first semi-circular groove 500 and the second semi-circular groove 501 form an integral circular groove. An elastic buffer plug 502 is inserted into the inner wall of the circular groove. The elastic buffer plug 502 includes an inner layer and an outer layer. The inner layer is made of a steel cylindrical rod, and the outer layer is made of polyurethane composite material.

[0045] Specifically, the active connector 100 is coaxially fixed to the main shaft of the centrifuge 300, and the driven connector 200 is coaxially connected to the main shaft of the motor 400. Then, an elastic buffer plug 502 is inserted into the circular groove. Through the precise alignment of the semi-circular groove, the transmission alignment is ensured, and the vibration deviation during high-speed operation is reduced. When the centrifuge 300 starts or the load fluctuates, the outer layer made of polyurethane composite material absorbs the torque impact, avoiding overload of the motor 400 caused by rigid transmission. The inner layer of steel cylindrical rod prevents material deformation and ensures long-term stability. This can significantly reduce the impact of changes in calcium carbonate slurry concentration on the transmission system and extend the equipment life.

[0046] Please refer to this carefully. Figure 4 and Figure 5 The active assembly cylinder 101 has an annular sealing boss 104 on the right side, and the driven assembly cylinder 201 has a sealing groove 203 on the left side that matches the annular sealing boss 104. A sealing ring is provided in the sealing groove 203. The annular sealing boss 104, the sealing ring and the sealing groove 203 cooperate to form a labyrinth-type sealing pair.

[0047] Specifically, the annular sealing boss 104, the sealing ring, and the sealing groove 203 cooperate to form a labyrinth-type sealing pair. Through a multi-level tortuous path, corrosive media and fine particles are blocked. The sealing ring enhances the initial sealing performance and prevents moisture and chemicals from seeping in during the calcium carbonate dehydration process.

[0048] Please refer to this carefully. Figure 2 , Figure 3 , Figure 6 , Figure 8 as well as Figure 10The left end of the active connector 100 is provided with an elastic buffer mechanism 600. The elastic buffer mechanism 600 includes a metal ring 601, a friction ring 602, a disc spring 603, and a pressure ring 604, which are sequentially fitted onto the surface of the bushing 103 from right to left. A sleeve 605 with a flange is fixedly installed on the surface of the bushing 103. Four sets of cylinders 606 are fixedly installed in a circumferential array on the right end of the sleeve 605. The cylinders 606 are supplied with air through an external air slip ring. The metal ring 601 is made of... The friction ring 602 is made of copper-based powder metallurgy and is made of spring steel with hard chrome plating. The pressure ring 604 is provided with pressure equalization grooves to ensure uniform pressure distribution. The left end of the active assembly cylinder 101 is fixedly installed with limit blocks 607 in a circumferential array. The inner ring surface of the metal ring 601 is provided with a groove 608 that matches the limit block 607. The left end of the limit block 607 is fixedly installed with a stop block 609. The inner ring surfaces of the friction ring 602, the butterfly spring 603 and the pressure ring 604 are all in contact with the surface of the stop block 609.

[0049] Specifically, after the slot 608 on the metal ring 601 is engaged with the limiting block 607, the metal ring 601 is limited to prevent rotation. The stop block 609 drives the friction ring 602, the butterfly spring 603, and the pressure ring 604 to be on the same central axis to prevent misalignment. The drive cylinder 606 provides thrust, and the clamping force of the butterfly spring 603 can be adjusted to ensure stable contact between the friction ring 602 and the metal ring 601. When the centrifuge 300 starts, the cylinder 606 extends slightly. At this time, the friction between the friction ring 602 and the metal ring 601 is small, and the friction ring 602 will rotate on the metal ring 601. As the cylinder 606 gradually extends, the friction ring 602 and the metal ring 601 are in stable contact, and the increased friction prevents the friction ring 602 from rotating, thus driving the centrifuge 300 to rotate smoothly. Therefore, the elastic buffer plug 502 can be protected to prevent overload.

[0050] The working principle of this embodiment is as follows:

[0051] When the motor 400 is driven, the cylinder 606 adjusts the clamping force of the disc spring 603 to achieve progressive contact between the friction ring 602 and the metal ring 601. During startup, the cylinder 606 extends slightly, allowing the friction ring 602 to slide and buffer the impact. After stable operation, the friction increases, ensuring smooth transmission and protecting the elastic buffer plunger 502 from overload damage. At the same time, the elastic buffer plunger 502 effectively reduces vibration deviation during high-speed operation, ensuring transmission alignment. The polyurethane outer layer absorbs torque impact, preventing motor 400 from overload, and the steel inner layer prevents material deformation, significantly reducing the impact of calcium carbonate slurry concentration fluctuations on the transmission system and extending equipment life.

[0052] Example 2

[0053] Compared with Embodiment 1, another implementation of this application is as follows:

[0054] Please refer to this carefully. Figure 2 , Figure 6 and Figure 9 The surfaces of the active connector 100 and the driven connector 200 are provided with locking mechanisms 700. The locking mechanism 700 includes a mounting ring 701 sleeved on the surface of the active assembly cylinder 101, four roller seats 702 fixedly mounted in a circumferential array on the inner annular surface of the mounting ring 701, four mounting grooves in a circumferential array on the outer surface of the active assembly cylinder 101, rollers 703 disposed on the inner wall of the roller seats 702, clamping plates 704 rotatably mounted on the inner wall of the mounting grooves, clamping discs 705 fixedly mounted on the outer surface of the driven assembly cylinder 201, and elastic reset components disposed on the surface of the active assembly cylinder 101. Furthermore, the clamping plate 704 has a flat surface and a sloping surface at one end near the roller 703. The elastic reset component includes a baffle 706 fixedly installed on the outer surface of the active assembly cylinder 101, four guide holes arranged in a circumferential array on the surface of the baffle 706, a guide rod 707 slidably fitted on the inner wall of the guide hole, and a reset spring 708 sleeved on the surface of the guide rod 707. One end of the guide rod 707 is fixedly connected to the left end of the mounting ring 701, and a positioning block 709 is fixedly installed on the other end of the guide rod 707. The two ends of the reset spring 708 abut against the opposite surfaces of the baffle 706 and the mounting ring 701, respectively.

[0055] Specifically, when the active connector 100 and the driven connector 200 are docked, the return spring 708 can drive the mounting ring 701 to move to the right, thereby driving the roller 703 on the roller seat 702 to move along the ramp surface on the clamping plate 704 to the plane. At this time, the clamping plate 704 can be driven to rotate and clamp the right end face of the clamping plate 705, thereby completing the quick installation of the active connector 100 and the driven connector 200. When the mounting ring 701 is pulled to the left, the guide rod 707 will slide along the inner wall of the guide hole to guide the roller seat 702. At this time, the roller 703 will move along the plane on the clamping plate 704 to the ramp surface, thereby driving the clamping plate 704 to rotate and disengage from the clamping plate 705 to achieve quick separation.

[0056] Please refer to this carefully. Figure 6 and Figure 9 An operating ring 710 is rotatably mounted on the outer surface of the mounting ring 701. Four locking blocks 711 are fixedly mounted in a circumferential array on the inner wall of the operating ring 710. The surface of the baffle 706 is provided with a through groove 712 for the locking blocks 711 to pass through. The surface of the operating ring 710 is provided with anti-slip texture.

[0057] Specifically, when the operating ring 710 is pulled to the left, the mounting ring 701 moves synchronously. When the clamping plate 704 rotates and disengages from the clamping plate 705, the locking block 711 moves along the through groove 712 to the left side of the retaining plate 706. Then, rotating the operating ring 710 drives the locking block 711 to move away from the through groove 712. The reset force of the return spring 708 drives the locking block 711 to contact the retaining plate 706, thereby limiting the operation ring 710 and preventing it from resetting. When it is necessary to assemble the active connector 100 and the driven connector 200, rotating the operating ring 710 drives the locking block 711 into the through groove 712, thereby driving the operating ring 710 to move to the right and causing the clamping plate 704 to rotate.

[0058] The working principle of this embodiment is as follows:

[0059] After the active connector 100 and the driven connector 200 are axially aligned, the return spring 708 generates a rightward thrust on the mounting ring 701. The mounting ring 701 then moves the roller seat 702 to the right, and the roller 703 rolls along the ramp surface of the clamping plate 704, forcing the clamping plate 704 to rotate inward around the inner wall of the mounting groove. When the roller 703 crosses the ramp surface and enters the planar area, the clamping end of the clamping plate 704 tightly engages with the end face of the clamping disc 705, forming a mechanical interlock. At this time, the return spring 708 ensures stable clamping force and prevents loosening during transmission. When it is necessary to separate the connectors, the operating ring 710 is manually pulled to the left, causing the mounting ring 701 to move. When the mounting ring 701 moves to the left, the locking block 711 slides along the through groove 712. Then, the operating ring 710 is rotated to make the locking block 711 misaligned with the through groove 712. The rebound force of the return spring 708 pushes the locking block 711 against the left side of the stop plate 706, forming a mechanical stop to prevent the operating ring 710 from resetting. When it is necessary to release the lock, the operating ring 710 is rotated in the opposite direction to make the locking block 711 realign with the through groove 712, releasing the limiting effect of the stop plate 706. Then, the return spring 708 pushes the mounting ring 701 to the right, and the roller 703 rolls along the slope of the clamping plate 704 to the plane, forcing the clamping plate 704 to rotate inward to clamp the clamping plate 705.

[0060] Operating steps:

[0061] 1. From right to left, place the metal ring 601, friction ring 602, butterfly spring 603 and pressure ring 604 onto the surface of the bushing 103. Then, insert the groove 608 of the metal ring 601 into the limiting block 607 at the left end of the active assembly cylinder 101 to ensure that the metal ring 601 is fixed and does not rotate. Confirm that the stop block 609 is in contact with the inner ring surface of the friction ring 602, butterfly spring 603 and pressure ring 604 to ensure coaxiality. Then, provide air source to the cylinder 606 through the external air slip ring, adjust the thrust of the cylinder 606, and control the clamping force of the butterfly spring 603.

[0062] 2. The active assembly cylinder 101 of the active connector 100 is coaxially fixed with the main shaft of the centrifuge 300 to ensure a stable connection. The driven assembly cylinder 201 of the driven connector 200 is coaxially connected with the main shaft of the motor 400. Then, the elastic buffer plug 502 is inserted into the circular groove. After that, a sealing ring is placed in the sealing groove 203. Then, the annular sealing boss 104 is inserted into the sealing groove 203 of the driven assembly cylinder 201. Then, the return spring 708 generates a rightward thrust, which pushes the mounting ring 701 to drive the roller seat 702 to move to the right. The roller 703 rolls along the slope of the clamping plate 704, forcing the clamping plate 704 to rotate inward around the mounting groove axis. When the roller 703 enters the planar area, the clamping end of the clamping plate 704 is tightly attached to the end face of the clamping plate 705 to form a mechanical interlock.

[0063] 3. Start the motor 400 to drive the centrifuge 300 to start running. When starting, the cylinder 606 extends slightly and the friction ring 602 slides on the metal ring 601 to buffer the initial impact. As the load stabilizes, the cylinder 606 gradually extends to increase the friction between the friction ring 602 and the metal ring 601, ensuring smooth transmission. The polyurethane outer layer of the elastic buffer plunger 502 absorbs the torque impact to prevent the motor 400 from being overloaded, and the steel inner layer maintains structural stability and reduces vibration deviation.

[0064] 4. To separate the connecting parts, manually pull the operating ring 710 to the left, causing the mounting ring 701 to move to the left simultaneously. The locking block 711 slides along the through groove 712 and enters the left limiting surface of the baffle 706. Rotate the operating ring 710 to misalign the locking block 711 with the through groove 712. The return spring 708 rebounds and pushes the locking block 711 against the left side of the baffle 706 to prevent the operating ring 710 from resetting. At this time, the roller 703 will move along the plane on the clamping plate 704 to the slope, thereby driving the clamping plate 704 to rotate and disengage from the clamping plate 705 to achieve rapid separation.
