Description

Technical Field

[0001] This invention relates to the field of metal powder processing technology, specifically to an automatic feeding rotary kiln. Background Technology

[0002] Rotary kilns, as core equipment for high-temperature calcination, are widely used in many industrial fields such as building materials production, metallurgy and mineralization, and harmless disposal of industrial solid waste. The continuous and stable operation of the rotary kiln directly determines the processing efficiency and product quality of the entire production line. In the existing rotary kiln feeding systems, most use independently set power drive units to provide power to the feeding mechanism. This requires additional configuration of dedicated motors, reduction gears, and matching synchronous control systems. This not only significantly increases the equipment investment cost and installation area of ​​the entire production line, but also leads to poor coordination between the feeding mechanism and the main body of the rotary kiln, further increasing energy consumption and equipment maintenance costs in the production process. At the same time, the setting of multiple independent drive systems also increases the probability of equipment failure, making it difficult to adapt to the continuous and low-cost operation requirements of rotary kilns.

[0003] Meanwhile, existing rotary kilns mostly employ fixed feeding structures in their feeding stages. When processing materials with high viscosity and uneven particle size distribution, material bridging and blockage are prone to occur in the feeding channel. This can lead to feeding interruptions and affect the continuity of rotary kiln feeding, or even require machine shutdown and manual unblocking, posing significant operational safety hazards and drastically reducing production efficiency. Existing solutions to address feeding blockage issues mostly involve adding an independently driven anti-blocking structure to the feeding mechanism. This not only further complicates the equipment structure but also makes it difficult to precisely match the operating rhythm of the rotary kiln and feeding mechanism. The anti-blocking effect is limited, failing to fundamentally solve the problem of coordinated operation and stable anti-blocking in the rotary kiln feeding stages, and also resulting in excessive energy consumption.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 This invention provides a technical solution: an automatic feeding rotary kiln, used to automatically supply unprocessed metal powder to the rotary kiln 1, comprising: The feeding mechanism 4 is located on the rotary kiln 1 and is connected to the discharge position of the feeding mechanism 2. The feeding mechanism 2 conveys the material to be fed into the rotary kiln 1 and pours it into the rotary kiln 1 through the feeding mechanism 4. The feeding mechanism 4 includes a movable plate 43 to prevent material blockage. The movable plate 43 is driven to rotate slightly, thereby moving the material entering the feed hopper 41 and preventing blockage. The movable plate 43 is driven by the rotary kiln 1 through the feeding mechanism 2. The feeding mechanism 4 has a locking interface 42 for locking the feeding mechanism 2, thus tightly connecting the feeding mechanism 2 and the feeding mechanism 4.

[0020] Please see Figures 6-9 The feeding mechanism 4 also includes a feeding hopper 41 connected to the rotary kiln 1. The feeding hopper 41 is wider at the top and narrower at the bottom, with openings at both the top and bottom. The lower opening is the same size as the feeding tank 11 on the rotary kiln 1 and is tightly connected to the feeding tank 11. A movable plate 43 is disposed in the feeding hopper 41. Both ends of the movable plate 43 are provided with connecting shafts 431. The movable plate 43 is disposed in the feeding hopper 41 through the connecting shafts 431 and can rotate in the feeding hopper 41. The movable plate 43 is driven by the rotary kiln 1 and can rotate repeatedly during feeding to prevent the materials from sticking together and causing jamming. A drive head 432 is connected to one end of the connecting shaft 431. The drive head 432 is connected to the transmission rod 44 to drive the movable plate 43 to rotate. The drive head 432 is equipped with a transmission rod 44, which is in contact with an eccentric wheel 46. The eccentric wheel 46 is used to change the rotational force of the feeding mechanism 2, which is also accompanied by lateral force, and transmit it to the movable plate 43 through the transmission rod 44. The eccentric wheel 46 is rotated by the feeding mechanism 2. The transmission rod 44 is driven to move by the eccentric wheel 46, changing the state of the connecting shaft 431 and driving the movable plate 43 to rotate.

[0021] The power of the feeding mechanism 4 is provided by the rotary kiln 1 through the feeding mechanism 2. The power is transmitted to the eccentric wheel 46, which then drives the eccentric wheel 46 to rotate. The eccentric wheel 46, through contact with the transmission rod 44, converts its own rotational power into the lateral reciprocating motion of the transmission rod 44. The reciprocating motion of the transmission rod 44 acts synchronously on the drive head 432, which drives the connecting shaft 431, which is fixedly connected to it, to rotate. The connecting shaft 431 is fixed to both ends of the movable plate 43, and thus the connecting shaft 431 drives the movable plate 43 to rotate with... The feed hopper 41 connected to the rotary kiln 1 reciprocates. The feed hopper 41 has a double-opening structure that is wider at the top and narrower at the bottom. Its lower opening is the same size as the feed tank 11 on the rotary kiln 1 and is tightly connected. During the feeding process, the movable plate 43, which moves synchronously with the rotary kiln 1, continuously agitates the material in the feed hopper 41 through continuous reciprocating swing, effectively avoiding the problem of material sticking together and causing jamming or blockage. This ensures that the material can be smoothly transported from the feed hopper 41 to the feed tank 11, so as to realize the continuous, stable and automatic supply of unprocessed metal powder by the rotary kiln 1.

[0022] Please see Figures 8-10An eccentric wheel 46 has a rim 461, which contacts a rotating wheel 441 on the transmission rod 44, and the rotating wheel 441 rotates on the rim 461. A rotating shaft 462 is connected to the other side of the rim 461, transmitting power from the second transmission rod 463 to the rim 461. The rotating shaft 462 is mounted on the mounting plate 47. The rotating shaft 462 and the rim 461 are eccentrically positioned, causing the rim 461 to rotate eccentrically around the axis of the rotating shaft 462. A second transmission rod 463 is mounted on the rotating shaft 462, and a transmission mechanism 3 is provided on the second transmission rod 463 and the feeding mechanism 2, thereby transmitting power from the feeding mechanism 2 to the second transmission rod 463 through the transmission mechanism 3, driving the rim 461 to rotate. A rotating wheel 441 is located at one end of the transmission rod 44, rotating on the rim 461 and transmitting power to the transmission rod 44. The other end of the transmission rod 44 is provided with a connector 444, which is located in the drive head 432 and transmits power to the drive head 432. A fixing plate 442 is provided in the middle, and an anti-compression spring 443 is connected to the fixing plate 442. A limiting plate 45 and a mounting plate 47 are provided on the feed hopper 41. The limiting plate 45 is connected to the other end of the anti-compression spring 443 and is penetrated by the transmission rod 44. The mounting plate 47 is connected by a rotating shaft 462. The anti-compression spring 443 is used to drive the transmission rod 44 to reset. The feed hopper 41 is provided with a limiting plate 45 and a mounting plate 47. The limiting plate 45 is connected to the other end of the anti-compression spring 443 and is penetrated by the transmission rod 44. The mounting plate 47 is connected by a rotating shaft 462. The other end of the compression spring 443 is connected to the limiting plate 45. When the rotating wheel 441 rotates in the rim 461, since the eccentric wheel 46 rotates around the center of the rotating shaft 462, the rim 461 will exert a pulling force on the rotating wheel 441. At this time, the compression spring 443 will be subjected to the pressure of the fixed plate 442. As the eccentric wheel 46 continues to rotate, the compression spring 443 releases the pressure, pushes the fixed plate 442 to reset the transmission rod 44. The pulling force and the rebound force are all applied to the movable plate 43 through the drive head 432, so that the movable plate 43 can rotate repeatedly. The rotating wheel 441 rotates in the rim 461, driving the transmission rod 44 to move. The two ends of the connector 444 are respectively provided with connecting rods 446, and the connecting rods 446 are provided with limiting heads 445. The drive head 432 has a sliding groove 4321 and an adapter groove 4322. The connector 444 is located in the adapter groove 4322, and the connecting rod 446 is located in the sliding groove 4321 and can slide in the sliding groove 4321. This allows the connector 444 to move adaptably in the adapter groove 4322 without any hard jamming.

[0023] The power output from the feeding mechanism 2 is transmitted to the second transmission rod 463 via the transmission mechanism 3, driving the rotating shaft 462, which is fixedly connected to the second transmission rod 463, to rotate. The rotating shaft 462 is rotatably mounted on the mounting plate 47 matching the feed hopper 41, and its end is fixedly connected to the rim 461 of the eccentric wheel 46. The rotating shaft 462 and the rim 461 are not concentrically arranged, so that when the rotating shaft 462 rotates, it drives the rim 461 to perform an eccentric rotation around the center of the rotating shaft 462. The rim 461 and the rotating wheel 461 are located at one end of the transmission rod 44. 41 contacts the eccentric wheel 461, which rolls along the surface of the rim 461 as the eccentric wheel 461 rotates eccentrically, converting the rotational motion of the eccentric wheel 46 into the lateral reciprocating motion of the transmission rod 44. A fixed plate 442 is fixedly provided in the middle of the transmission rod 44, and a compression spring 443 is connected to the fixed plate 442. The other end of the compression spring 443 is connected to a limiting plate 45 fixed on the feed hopper 41. When the eccentric rotation of the rim 461 pushes the transmission rod 44 to move through the wheel 441, the fixed plate 442 moves synchronously. The compression spring 443 is compressed to store energy. As the eccentric wheel 46 continues to rotate, the compression spring 443 releases its elastic force to push the fixed plate 442 and drive the transmission rod 44 to reverse and reset, thereby realizing the continuous reciprocating linear motion of the transmission rod 44. The other end of the transmission rod 44 is provided with a connector 444, and the two ends of the connector 444 are respectively provided with connecting rods 446. The end of the connecting rod 446 is provided with a limiting head 445. The drive head 432 that cooperates with the transmission rod 44 is provided with an adapter groove 4322 and a sliding groove 432. 1. The connector 444 is located in the adapter groove 4322, and the connecting rod 446 is correspondingly inserted in the slide groove 4321 and can slide along the slide groove 4321. This mating structure allows the connector 444 to complete the adaptive displacement in the adapter groove 4322, avoiding hard jamming during transmission. At the same time, it stably transmits the reciprocating movement power of the transmission rod 44 to the drive head 432, and finally drives the connecting shaft 431 to rotate through the drive head 432, realizing the continuous reciprocating swing of the movable plate 43, and achieving the anti-blocking effect in the feeding process.

[0024] Example 1: When the rotary kiln 1 is running, its own power is synchronously transmitted to the feeding mechanism 2, driving the feeding mechanism 2 to run. The feeding mechanism 2 is tightly engaged and fixed with the feeding mechanism 4 through the snap-fit ​​interface 42 on the feeding mechanism 4, conveying the material to be processed to the feeding mechanism 4. At the same time, the power of the feeding mechanism 2 is transmitted to the second transmission rod 463 of the feeding mechanism 4 through the transmission mechanism 3, driving the rotating shaft 462, which is fixedly connected to the second transmission rod 463, to rotate. The rotating shaft 462 is rotatably mounted on the mounting plate 47 matching the feeding hopper 41, and its end is fixedly connected to the wheel rim 461 of the eccentric wheel 46. The rotating shaft 462 and the wheel rim 461 are not concentrically arranged, so that when the rotating shaft 462 rotates, it drives the wheel rim 461 to rotate eccentrically around the center of the rotating shaft 462. During rotation, the rim 461 contacts the rotating wheel 441 at one end of the transmission rod 44. The rotating wheel 441 rolls along the surface of the rim 461 as the eccentric wheel 461 rotates, converting the rotational motion of the eccentric wheel 46 into the lateral reciprocating motion of the transmission rod 44. A fixed plate 442 is fixed in the middle of the transmission rod 44, and a compression spring 443 is connected to the fixed plate 442. The other end of the compression spring 443 is connected to a limiting plate 45 fixed on the feed hopper 41, and the transmission rod 44 passes through the limiting plate 45. When the eccentric rotation of the rim 461 pushes the transmission rod 44 to move through the rotating wheel 441, the fixed plate 442 simultaneously squeezes the compression spring 443 to compress and store energy. As the eccentric wheel 46 continues to rotate, the compression spring... 443 releases elastic force to push the fixed plate 442, causing the transmission rod 44 to reverse and reset, thereby realizing the continuous reciprocating linear motion of the transmission rod 44. The other end of the transmission rod 44 is provided with a connector 444, and each end of the connector 444 is provided with a connecting rod 446. The end of the connecting rod 446 is provided with a limiting head 445. The drive head 432 that cooperates with the transmission rod 44 has an adapter groove 4322 and a sliding groove 4321. The connector 444 is located in the adapter groove 4322, and the connecting rod 446 is correspondingly inserted into the sliding groove 4321 and can slide along the sliding groove 4321. This mating structure allows the connector 444 to complete the adaptive displacement within the adapter groove 4322, avoiding hard jamming during transmission, and simultaneously reducing the reciprocating motion of the transmission rod 44. The moving power is stably transmitted to the drive head 432. The drive head 432 is fixedly connected to the connecting shaft 431 at the end of the movable plate 43. The connecting shaft 431 is rotatably located in the feed hopper 41. The feed hopper 41 is connected to the rotary kiln 1 and has a double-opening structure that is wider at the top and narrower at the bottom. Its lower opening is the same size as the feed tank 11 on the rotary kiln 1 and is tightly connected. The drive head 432 drives the movable plate 43 to continuously reciprocate in the feed hopper 41 through the connecting shaft 431. During the feeding process, the material in the feed hopper 41 is continuously disturbed, which effectively avoids the problem of material sticking together and getting stuck or blocked. This ensures that the material is smoothly transported from the feed hopper 41 to the feed tank 11, and finally realizes the continuous, stable and automatic supply of unprocessed metal powder to the rotary kiln 1.

[0025] Please see Figures 1-2The feeding mechanism 2 is used to feed material into the rotary kiln 1. The feeding mechanism 2 is connected to the rotary kiln 1 via a drive mechanism, and its power is provided by the rotary kiln 1. The feeding mechanism 2 includes a frame 21, within which a power wheel 22 is installed. A conveyor belt 23 is sleeved on the outer side of the power wheel 22. When the power wheel 22 is driven to rotate by the rotary kiln 1, it drives the conveyor belt 23 to operate, thereby achieving feeding. One end of the conveyor belt 23 is provided with a first transmission rod 24, which is connected to a transmission mechanism 3. The first transmission rod 24 drives the feeding mechanism 4 through the transmission mechanism 3. The transmission mechanism 3 includes a first pulley 31 mounted on the first transmission rod 24 and a second pulley 33 mounted on the second transmission rod 463. A synchronous belt 32 is sleeved on the first pulley 31 and the second pulley 33, which is used to transmit the power of the feeding mechanism 2 to the feeding mechanism 4.

[0026] When the rotary kiln 1 is running, its output power is synchronously transmitted to the feeding mechanism 2, which is connected to its own transmission. This drives the power wheel 22 installed inside the frame 21 of the feeding mechanism 2 to rotate. The rotating power wheel 22 drives the conveyor belt 23 sleeved on its outer side to run continuously, completing the conveying operation of the material to be processed towards the rotary kiln 1, realizing the automatic supply of unprocessed metal powder by the rotary kiln 1. At the same time, the first transmission rod 24, which is matched with one end of the conveyor belt 23, rotates synchronously with the operation of the feeding mechanism 2. The first transmission rod 24 is connected to the transmission mechanism 3, driving the first pulley 31, which is fixedly installed on the first transmission rod 24, to rotate synchronously. The first pulley 31 transmits power synchronously to the second pulley 33, which is fixedly installed on the second transmission rod 463, through the synchronous belt 32 sleeved between it and the second pulley 33. This drives the second transmission rod 463 to rotate synchronously, and finally stably transmits the power of the feeding mechanism 2 to the feeding mechanism 4, providing the same power source that is completely synchronized with the feeding and kiln operation for the anti-blocking action of the feeding link.

[0027] Please see Figures 1-5 The rotary kiln 1 includes an outer shell 14, which protects the internal structure of the rotary kiln 1. An inner tank 12 is housed within the outer shell 14 and rotates within it. A transmission gear 13 is mounted on the inner tank 12, rotating synchronously with it. A feed tank 11 is located at one end of the outer shell 14, connected to the inner tank 12. A discharge port 15 is located at the other end, used to discharge materials. The feed tank 11 is connected to the feeding mechanism 4.

[0028] A gearbox 34 is provided on the outer side of the transmission gear 13. A gear is provided on the inner side of the gearbox 34, and an insertion port 341 is provided on one side of the gearbox 34. The insertion port 341 is fitted onto the outer side of the transmission gear 13. The gear in the gearbox 34 meshes with the transmission gear 13. When the transmission gear 13 rotates, it drives the gear inside the gearbox 34 to rotate together. A gear rod 35 is connected to the gearbox 34. The gear rod 35 is connected to the gear inside the gearbox 34 and is driven to rotate. A steering box 36 is provided at one end of the gear rod 35. The steering box 36 is used to change the direction of transmission of the gear rod 35. The steering box 36 is also provided with a gear rod 35. There are at least two steering boxes 36 and gear rods 35, and they are connected to each other. They are used to transmit the power of the rotary kiln 1 to the feeding mechanism 2.

[0029] During the operation of the rotary kiln 1, the outer shell 14 serves to protect the internal components. The inner tank 12 inside the outer shell 14 rotates continuously to complete the calcination of materials. The transmission gear 13 installed on the inner tank 12 rotates synchronously with the inner tank 12. The feed tank 11 at one end of the outer shell 14 is connected to the inner tank 12 and docks with the feeding mechanism 4 for feeding materials. The discharge port 15 at the other end is used to discharge the processed materials. A gearbox 34 is provided on the outside of the transmission gear 13. The gearbox 34 is sleeved on the outside of the transmission gear 13 through an insertion port 341 on one side. On the side, its internal gear meshes with the transmission gear 13, and rotates synchronously with the transmission gear 13. The gear rod 35 connected to the gearbox 34 is connected to the gear inside the gearbox 34 and is driven to rotate. The steering box 36 at the end of the gear rod 35 is used to adjust the direction of power transmission. At least two steering boxes 36 and matching gear rods 35 are provided and connected in sequence to transmit power. Finally, the rotational power of the rotary kiln 1 is stably transmitted to the feeding mechanism 2, realizing the automatic supply of unprocessed metal powder and the anti-blocking function of feeding through the same source drive of the whole machine.

[0030] When the rotary kiln with automatic feeding is in use, the rotary kiln 1 starts up, and the inner tank 12 inside its outer shell 14 rotates continuously to complete the calcination of materials. The transmission gear 13, which rotates synchronously with the inner tank 12, extracts rotational power through the gears inside the meshing gearbox 34. Then, through multiple sets of sequentially transmitted gear rods 35 and steering box 36, the transmission direction is adjusted and the power is transmitted. Finally, the main driving power of the rotary kiln 1 is synchronously output to the feeding mechanism 2.

[0031] After the feeding mechanism 2 obtains the same power source as the rotary kiln 1, it drives the power wheel 22 in the drive frame 21 to rotate, which drives the conveyor belt 23 to operate continuously, completing the continuous conveying of the material to be processed to the feeding mechanism 4; at the same time, the first transmission rod 24 linked with the conveyor belt 23 rotates synchronously, and outputs power synchronously to the transmission mechanism 3, realizing the complete synchronization of material conveying and power distribution.

[0032] The transmission mechanism 3 transmits power flawlessly to the second pulley 33 via the first pulley 31 that rotates with the first transmission rod 24 and the synchronous belt 32, thereby driving the second transmission rod 463 to rotate synchronously and stably transmit the power of the feeding mechanism 2 to the feeding mechanism 4, ensuring that the subsequent anti-blocking action is precisely matched with the kiln operation and feeding rhythm.

[0033] After the feeding mechanism 4 obtains power, the second transmission rod 463 drives the eccentric wheel 46 to perform eccentric rotational motion through the rotating shaft 462; relying on the non-concentric setting of the rotating shaft 462 and the wheel rim 461, the eccentric wheel 46 converts its rotational motion into the transverse reciprocating linear motion of the transmission rod 44 through the rotating wheel 441 that abuts against the wheel rim 461; during the operation of the transmission rod 44, the compression energy storage and elastic reset are completed simultaneously through the anti-compression spring 443 between the fixing plate 442 and the limiting plate 45 in the middle of the rod body, ensuring the continuity and stability of the reciprocating motion of the transmission rod 44; the connector 444 at the end of the transmission rod 44 is connected to the adapter on the drive head 432 The trough 4322 and slide 4321 are adapted for transmission, which not only avoids hard jamming during the transmission process, but also stably transmits the reciprocating power to the connecting shaft 431, which ultimately drives the movable plate 43 to continuously reciprocate within the feed hopper 41, continuously agitating the feed material and effectively breaking down the problems of material sticking, bridging, and blockage. The material conveyed by the feeding mechanism 2 smoothly enters the inner tank 12 through the feed hopper 41 and feed tank 11 to complete the calcination treatment, and is finally discharged from the discharge port 15. This realizes the automatic supply of unprocessed metal powder and continuous and stable operation of the rotary kiln driven by a single power source. It also realizes one power source and three drives, which greatly saves energy consumption.
