Technical Field

[0001] This invention relates to a ball mill ball feeding device, specifically a multi-channel ball mill ball feeding device, belonging to the field of ball mill technology. Background Technology

[0002] Ball mills are key pieces of equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics, for dry or wet grinding of various ores and other grindable materials.

[0003] Patent CN113786908A discloses a bidirectional ball feeding method for a ball mill ball feeder, comprising the following steps: S1: A ball feeding groove is arranged at the bottom of the ball chamber outlet, with a left ball outlet and a right ball outlet respectively provided at both ends of the ball feeding groove; S2: A ball-distributing rotary device is arranged on one side of the ball feeding groove, driven by a horizontal rotating disk, the horizontal rotating disk being driven to rotate by a drive assembly, and the ball-distributing rotary device having multiple ball-distributing baffles spaced circumferentially. In practical applications, bidirectional ball feeding is achieved, enabling simultaneous ball supply to two ball mills, effectively improving the efficiency and automation of steel ball feeding.

[0004] When grinding materials in a ball mill, there is a need to install grinding media and add grinding balls of different sizes to the inside of the ball mill in a measured quantity. Although the ball adding device in the aforementioned patent is convenient for bidirectional ball adding, the size of the added balls is relatively fixed. When it is necessary to add grinding balls of different sizes, the grinding balls inside the ball trough need to be cleaned out and replaced with the required grinding balls, which increases the difficulty of ball adding to the ball mill and reduces the ball adding efficiency. To address these issues, we have provided a multi-channel ball adding device for ball mills. Summary of the Invention

[0014] Preferably, a hydraulic push rod is fixedly connected to the surface of the grinding ball storage box, and a positioning frame is engaged at the output end of the hydraulic push rod. A chain tension wheel is rotatably connected inside the positioning frame, and the chain tension wheel is connected to the chain drive. A sliding block is fixedly connected to the surface of the positioning frame, and a positioning groove is fixedly connected to the surface of the grinding ball storage box. The sliding block is slidably connected to the positioning groove. The hydraulic push rod provides thrust to the positioning frame, and the positioning frame drives the chain tension wheel to squeeze the chain, so that the chain maintains a suitable tension state, improving the stability of the chain drive. The positioning frame is positioned by the sliding block and the positioning groove, so that the positioning frame can only slide laterally, improving the stability of the positioning frame's sliding.

[0015] Preferably, a fixed plate is fixedly connected to the surface of the grinding ball storage box, and a rotating shaft positioning frame is slidably connected to the middle of the fixed plate. The two ends of the rotating shaft positioning frame are rotatably connected to the two ends of the linkage rotating shaft. An electric push rod is fixedly connected to the surface of the fixed plate, and the output end of the electric push rod is fixedly connected to the rotating shaft positioning frame. The electric push rod provides thrust to the rotating shaft positioning frame, adjusts the position of the rotating shaft positioning frame laterally, and controls the power transmission block to engage with different connecting rings, thereby improving the stability of the linkage rotating shaft controlling the rotation of the linkage sleeve.

[0016] Preferably, the surface of the linkage rotating shaft is fixedly connected with power transmission blocks arranged at equal intervals, and the inside of the linkage sleeve is fixedly connected with connecting rings. The connecting rings are evenly arranged inside the linkage sleeve, and the power transmission blocks are engaged with the connecting rings.

[0017] This invention provides a multi-channel ball feeding device for a ball mill, which has the following beneficial effects: This multi-channel ball mill feeding device uses ball chutes to transport appropriately sized grinding balls into the mill, improving the convenience of ball mill feeding. Several ball sorting and storage bins store grinding balls of different sizes, enhancing storage and feeding convenience. A stirring rod agitates the grinding balls within the sorting and storage bins, preventing them from jamming and improving feeding convenience and smoothness. A linkage sleeve controls the rotation of the ball discharge wheel within the sorting and storage bins, quantitatively discharging the grinding balls and improving feeding efficiency. A power transmission shaft controls the rotation of the stirring rod, further agitating the grinding balls within the sorting and storage bins. A linkage rotating shaft controls the rotation of the corresponding linkage sleeve, causing the ball discharge wheel to quantitatively discharge the selected grinding balls. By adding appropriately sized grinding balls to the mill as needed, the device improves the stability and convenience of ball mill feeding.

[0018] This multi-channel ball-feeding device for a ball mill uses a fixed support frame for secure installation, improving the ease of installation and reducing maintenance difficulty. It enhances the overall convenience of ball feeding. A vibrating plate drives the ball-feeding slide to vibrate, allowing for better ball delivery into the mill. Telescopic springs and support rods provide support and fixation to the ball-feeding slide, improving its operational ease. The telescopic springs amplify the vibration of the slide, increasing its vertical vibration amplitude and reducing the probability of balls getting stuck in the ball grooves, thus improving the smoothness of ball delivery. A sealing cover seals the ball sorting and storage compartment. To improve the stability of grinding balls stored in the grinding ball sorting and storage bin, a scale indicator plate displays the number of grinding balls inside the bin, providing a more intuitive understanding of the quantity. When the number of grinding balls is low, they can be added promptly. A quantitative dispensing bin stores the grinding balls. By controlling the number of rotations of the dispensing wheel, a quantitative dispensing bin transports a fixed quantity of grinding balls from the grinding ball sorting and storage bin to the grinding ball chute, improving the quantitative dispensing accuracy. When the power transmission block is not engaged with the connecting ring, a double-sided damping ring positions the dispensing wheel and the linkage sleeve, preventing the dispensing wheel from rotating and improving the accuracy of grinding ball delivery.

[0019] This ball mill's multi-channel ball feeding device uses a fixing ring and bearings to position and fix the linkage components, improving their rotational stability. The drive sprocket and chain control the synchronous rotation of the transmission sprocket, which in turn controls the rotation of the linkage shaft, ensuring synchronous rotation with the power transmission shaft. A linkage block and sliding groove assemble the linkage components and the linkage shaft together, allowing the linkage components to drive the shaft's synchronous rotation and further enhancing its stability. A protective shell provides sealing and protection for the drive sprocket and transmission sprocket, improving the stability and convenience of the sprocket drive. A hydraulic push rod provides thrust to the positioning frame, which in turn tensions the chain. The wheel squeezes the chain to maintain proper tension, improving the stability of the chain drive. A sliding block and positioning groove position the positioning frame, allowing it to slide only laterally, thus improving its sliding stability. A fixed plate positions the rotating shaft positioning frame, further enhancing its lateral sliding stability. An electric push rod provides thrust to the rotating shaft positioning frame, adjusting its position laterally. This, in turn, controls the power transmission block to engage with different connecting rings, improving the stability of the linkage rotating shaft controlling the linkage sleeve's rotation. Finally, the power transmission block's engagement with different connecting rings allows the linkage rotating shaft to control the linkage sleeve's rotation, improving both the stability and convenience of the linkage sleeve's rotation.

[0022] This invention provides a multi-channel ball feeding device for a ball mill.

[0023] Please see Figure 1 The device includes a grinding ball storage box 1, with fixed support frames 2 fixedly connected to each of the four corners of the grinding ball storage box 1. The fixed support frames 2 are assembled and connected to the fixed frame of the ball mill by bolts. The device is fixedly installed through the fixed support frames 2, which improves the convenience of fixed installation of the ball adding device, reduces the maintenance difficulty of the ball adding device, and improves the convenience of adding balls to the ball mill. Grinding balls are added to the ball mill through the grinding ball storage box 1.

[0024] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The bottom of the grinding ball storage box 1 is provided with a ball discharging mechanism 3. The ball discharging mechanism 3 includes a grinding ball chute 301 that is fixedly connected to the grinding ball storage box 1. Through the grinding ball chute 301, grinding balls of appropriate size are transported into the ball mill, improving the convenience of adding balls to the ball mill.

[0025] The grinding ball slide 302 is hinged inside the grinding ball slide 301. A vibrating plate 303 is fixedly connected to the middle of the grinding ball slide 302. When the vibrating plate 303 is energized, it can drive the grinding ball slide 302 to vibrate synchronously, so that the vibrating plate 303 can better transport the grinding balls into the grinding machine, avoid the grinding balls getting stuck inside the grinding ball slide 301 and causing the grinding ball slide 301 to be blocked, and improve the convenience of adding balls to the grinding machine.

[0026] The vibrating plate 303 can be made of piezoelectric ceramic sheet. When voltage is applied to the piezoelectric ceramic, it will produce mechanical deformation with the change of voltage and frequency. Based on this principle, a vibrator is made of two piezoelectric ceramic sheets or one piezoelectric ceramic sheet and one metal sheet.

[0027] A support rod 304 is fixedly connected to the surface of the grinding ball slide plate 302, and the support rod 304 passes through the grinding ball slide groove 301 and is slidably connected to the slide groove on the surface of the grinding ball slide groove 301. A telescopic spring 305 is fixedly connected to the surface of the support rod 304, and the top end of the telescopic spring 305 is fixedly connected to the grinding ball slide groove 301. Through the telescopic spring 305 and the support rod 304, the grinding ball slide plate 302 is supported and fixed, improving the convenience of the operation of the grinding ball slide plate 302. The telescopic spring 305 can amplify the vibration of the grinding ball slide plate 302, increase the vertical vibration amplitude of the grinding ball slide plate 302, reduce the probability of the grinding ball getting stuck inside the grinding ball slide groove 301, and improve the smoothness of the grinding ball conveying of the grinding ball by the grinding ball slide plate 302.

[0028] If it is necessary to add balls to multiple ball mills, the bottom end of the ball mill chute 301 can be connected to a steering device. The ball milling device can be used to add balls to two or more ball mills through its outlet, thereby allowing the ball adding device to add balls to multiple ball mills in sequence, improving the convenience of ball adding.

[0029] Please refer to it again. Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The grinding ball storage box 1 is equipped with an equidistantly arranged ball-separating mechanism 4. The ball-separating mechanism 4 includes a grinding ball classification and storage bin 401, a stirring rod 403, and a linkage sleeve 406. The grinding ball classification and storage bin 401 is located inside the grinding ball storage box 1. Different sizes of grinding balls are stored through several grinding ball classification and storage bins 401, which improves the convenience of grinding ball storage and ball addition. The stirring rod 403 stirs the grinding balls inside the grinding ball classification and storage bin 401 to prevent the grinding balls from jamming together, which improves the convenience and smoothness of grinding ball addition.

[0030] A ball-discharging wheel 404 is fixedly connected to the surface of the linkage sleeve 406. The ball-discharging wheel 404 is controlled to rotate inside the grinding ball classification and storage bin 401 by the linkage sleeve 406, so as to quantitatively transport the grinding balls inside the grinding ball classification and storage bin 401 and improve the grinding ball loading efficiency.

[0031] The stirring rod 403 is fixed to the surface of the power conveying shaft 501, and the stirring rod 403 is located directly above the ball output wheel 404. The surface of the grinding ball storage box 1 is rotatably connected to a sealing cover plate 409 that is compatible with the grinding ball classification storage bin 401. The grinding ball storage box 1 is fixedly connected to a scale indicator plate 402 that is compatible with the grinding ball classification storage bin 401. The sealing cover plate 409 seals the grinding ball classification storage bin 401, improving the stability of the grinding balls stored in the grinding ball classification storage bin 401. The scale indicator plate 402 displays the number of grinding balls inside the grinding ball classification storage bin 401, allowing for a more intuitive understanding of the number of grinding balls inside the grinding ball classification storage bin 401. When the number of grinding balls is low, grinding balls can be added to the grinding ball classification storage bin 401 in a timely manner.

[0032] The ball-eating wheel 404 has a circumferentially arranged quantitative ball-eating chamber 405 on its surface. The quantitative ball-eating chamber 405 stores the grinding balls. When the ball-eating wheel 404 rotates, the number of rotations of the ball-eating wheel 404 is controlled so that the quantitative ball-eating chamber 405 transports a quantitative amount of grinding balls from the grinding ball classification and storage chamber 401 to the grinding ball chute 301, thereby improving the quantitative distribution of grinding balls.

[0033] A double-sided damping ring 407 is fixedly connected to the surface of the grinding ball sorting and storage bin 401. The double-sided damping ring 407 is a mature technology. This application can use existing equipment that can limit the movement of the linkage sleeve 406. The outer ring of the double-sided damping ring 407 is damped and rotatedly connected to the inner ring of the ball discharge wheel 404, and the inner ring of the double-sided damping ring 407 is damped and rotatedly connected to the surface of the linkage sleeve 406. When the power transmission block 410 is not engaged with the connecting retaining ring 408, the double-sided damping ring 407 positions the ball discharge wheel 404 and the linkage sleeve 406, preventing the ball discharge wheel 404 from rotating and improving the accuracy of grinding ball conveying.

[0034] Please refer to it again. Figure 4 and Figure 5 The surface of the linkage rotating shaft 506 is fixedly connected with power transmission blocks 410 arranged at equal intervals, and the inside of the linkage sleeve 406 is fixedly connected with connecting rings 408. The connecting rings 408 are evenly arranged inside the linkage sleeve 406. The power transmission blocks 410 are engaged with the connecting rings 408. By engaging the power transmission blocks 410 with different connecting rings 408, the linkage rotating shaft 506 controls the rotation of the linkage sleeve 406, thereby improving the stability and convenience of the rotation of the linkage sleeve 406.

[0035] If the power transmission block 410 moves to the left, it engages with the leftmost connecting ring 408. At the same time, the remaining power transmission blocks 410 disengage from the connecting ring 408. The remaining linkage sleeve 406 can be positioned and limited by the double-sided damping ring 407, preventing the linkage sleeve 406 from rotating arbitrarily and improving the accuracy of ball output from the grinding mill.

[0036] Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The grinding ball storage box 1 is equipped with a power mechanism 5, which includes a power conveying shaft 501 and a linkage rotating shaft 506. The power conveying shaft 501 is rotatably connected to the grinding ball storage box 1. A power device for controlling the rotation of the power conveying shaft 501 is fixedly connected to the surface of the grinding ball storage box 1. The power device is a mature technology, and this application can use existing equipment that can control the rotation of the power conveying shaft 501. The linkage rotating shaft 506 is movably connected to the grinding ball storage box 1. The power conveying shaft 501 controls the rotation of the stirring rod 403 to stir the grinding balls inside the grinding ball classification storage bin 401. The linkage rotating shaft 506 controls the rotation of the corresponding linkage sleeve 406 to make the ball discharge wheel 404 quantitatively deliver the selected grinding balls. Grinding balls of appropriate size are added to the grinding ball machine as needed, improving the stability and convenience of grinding ball addition.

[0037] One end of the power transmission shaft 501 is fixedly connected to a power sprocket 502. The power sprocket 502 is connected to a transmission sprocket 503 via a chain drive. A linkage component 504 is assembled and connected in the middle of the transmission sprocket 503. A fixing ring 505 is fixedly connected to the surface of the grinding ball storage box 1. The linkage component 504 is rotatably connected to the fixing ring 505 via a bearing. The fixing ring 505 and the bearing are used to position and fix the linkage component 504, thereby improving the rotational stability of the linkage component 504. The power sprocket 502 and the chain can control the synchronous rotation of the transmission sprocket 503. The transmission sprocket 503 and the linkage component 504 can control the rotation of the linkage rotating shaft 506, so that the linkage rotating shaft 506 rotates synchronously with the power transmission shaft 501.

[0038] The linkage component 504 is sleeved on the outside of the linkage rotating shaft 506. The surface of the linkage rotating shaft 506 is provided with a sliding groove 507. The linkage block 508 is fixedly connected inside the linkage component 504, and the linkage block 508 is slidably connected to the sliding groove 507. The protective shell 517 is movably connected to the surface of the linkage component 504. The protective shell 517 is sleeved on the outside of the chain and is fixedly connected to the grinding ball storage box 1. The linkage component 504 and the linkage rotating shaft 506 are assembled together through the linkage block 508 and the sliding groove 507. When the linkage rotating shaft 506 moves laterally, the linkage component 504 and the linkage rotating shaft 506 maintain a stable connection. The rotation of the linkage component 504 can drive the linkage rotating shaft 506 to rotate synchronously, improving the stability of the rotation of the linkage rotating shaft 506. The protective shell 517 provides sealing and protection for the power sprocket 502 and the transmission sprocket 503, improving the stability and convenience of the sprocket drive.

[0039] A hydraulic push rod 514 is fixedly connected to the surface of the grinding ball storage box 1. The hydraulic push rod 514 is a mature technology, and this application can use existing equipment that provides sufficient tension to the chain tensioning wheel 513. A positioning frame 512 is snapped onto the output end of the hydraulic push rod 514. The chain tensioning wheel 513 is rotatably connected inside the positioning frame 512 and is connected to the chain drive. A sliding block 515 is fixedly connected to the surface of the positioning frame 512, and a positioning groove 516 is fixedly connected to the surface of the grinding ball storage box 1. The sliding block 515... 5 is slidably connected to the positioning groove 516. The hydraulic push rod 514 provides thrust to the positioning frame 512. The positioning frame 512 drives the chain tension wheel 513 to squeeze the chain, so that the chain maintains a proper tension state and improves the stability of the chain transmission. The sliding block 515 and the positioning groove 516 position the positioning frame 512 so that the positioning frame 512 can only slide laterally, avoiding longitudinal swing of the positioning frame 512 and improving the stability of the lateral sliding of the positioning frame 512. In turn, the chain tension wheel 513 provides a stable tension force to the chain.

[0040] A fixed plate 510 is fixedly connected to the surface of the grinding ball storage box 1. A rotating shaft positioning frame 509 is slidably connected to the middle of the fixed plate 510, and both ends of the rotating shaft positioning frame 509 are rotatably connected to both ends of the linkage rotating shaft 506. An electric push rod 511 is fixedly connected to the surface of the fixed plate 510, and the output end of the electric push rod 511 is fixedly connected to the rotating shaft positioning frame 509 by bolts. The electric push rod 511 is a mature technology. This application can use existing equipment to control the movement of the rotating shaft positioning frame 509. The fixed plate 510 is used to position the rotating shaft positioning frame 509, thereby improving the stability of the lateral sliding of the rotating shaft positioning frame 509. The electric push rod 511 provides thrust to the rotating shaft positioning frame 509, adjusts the position of the rotating shaft positioning frame 509 laterally, and controls the power transmission block 410 to engage with different connecting rings 408, thereby improving the stability of the linkage rotating shaft 506 in controlling the rotation of the linkage sleeve 406.

[0041] Both ends of the power transmission block 410 are arc-shaped, and the corners of the connecting ring 408 are also arc-shaped. The arc shape makes it easier for the power transmission block 410 to be inserted into the connecting ring 408. When the power transmission block 410 needs to be inserted into the connecting ring 408, the linkage rotating shaft 506 controls the power transmission block 410 to rotate slowly, so that the power transmission block 410 rotates on the surface of the connecting ring 408. The two ends of the linkage rotating shaft 506 are fixed by the rotating shaft positioning frame 509. The electric push rod 511 controls the rotating shaft positioning frame 509 to move laterally, which drives the linkage rotating shaft 506 to move laterally, so that the power transmission block 410 can be inserted into the connecting ring 408 more quickly, improving the accuracy and speed of the connection between the connecting ring 408 and the power transmission block 410.

[0042] The vibrating plate 303, motor and electric push rod 511 are all electrically connected to the controller of the ball mill. The controller can control the start and stop of the vibrating plate 303, motor and electric push rod 511, improving the convenience of power unit control operation.

[0043] Working principle: The ball-adding device is fixedly installed by the fixed support frame 2. The balls are added to the corresponding ball classification and storage bins 401 according to their size. When small balls need to be added, they are located at the end of the device closest to the protective shell 517. The rotating shaft positioning frame 509 is moved by the electric push rod 511. The rotating shaft positioning frame 509 drives the linkage rotating shaft 506 to move to the left towards the protective shell 517, so that the power transmission block 410 is engaged with the connecting ring 408 on the left. The power transmission shaft 501 is rotated by the motor, which drives the stirring rod 403 to rotate, stirring the balls inside the ball classification and storage bins 401. At the same time, the transmission sprocket 503 can be controlled to rotate synchronously by the power sprocket 502 and the chain. The transmission sprocket 503 drives the linkage 504 to rotate, passing through the linkage block 508 and the sliding groove 507. The transmission mechanism causes the power transmission shaft 501 to drive the linkage rotating shaft 506 to rotate synchronously. The linkage rotating shaft 506 drives the connecting retaining ring 408 to rotate via the power transmission block 410, which in turn drives the ball discharge wheel 404 to rotate via the linkage sleeve 406. By controlling the number of rotations of the ball discharge wheel 404, the quantitative ball discharge chamber 405 transports a quantitative amount of grinding balls from the grinding ball classification storage chamber 401 to the grinding ball chute 301. The vibration plate 303 drives the grinding ball slide plate 302 to vibrate, which allows the vibration plate 303 to better transport the grinding balls into the grinding machine, improving the convenience of adding balls to the grinding machine. The linkage sleeve 406, which is far away from the power transmission block 410 and the connecting retaining ring 408, is prevented from rotating due to the restriction of the double-sided damping ring 407. Through the above device, grinding balls of appropriate size can be quantitatively added to the grinding machine according to the needs, improving the stability and convenience of adding grinding balls.
