Description

Technical Field

[0001] The present invention relates to the technical field of ball mills, and particularly to a device for replacing the lining plate of a ball mill. Background Art

[0002] A ball mill is a key device for crushing materials and then pulverizing them. The lining plate of a ball mill is used to protect the cylinder body from the direct impact and friction of grinding media and materials. At the same time, different forms of lining plates can be used to adjust the movement state of the grinding media to enhance the pulverizing effect of the grinding media on the materials, which helps to improve the grinding efficiency of the ball mill.

[0003] The patent with the application number 2019221865387 relates to a special hoisting device for replacing the lining plate of a ball mill, including a bottom plate, a pull rod, an insertion plate, a winch, and a guiding shell. The pull rod is horizontally arranged in the middle of the back of the bottom plate, the insertion plate is vertically arranged at the rear of the pull rod, the winch is arranged in front of the bottom plate, and the guiding shell is arranged under the winch. However, the safety of this device is poor during use, and a large amount of manual labor is still required for installation, resulting in a poor replacement efficiency of the ball mill lining plate.

[0004] The patent with the application number 201822231640X relates to a device for replacing the lining plate of a medium and small-sized mill, including a detachable column, a swing arm, a suspension cable, and a hydraulic power station. The column, the suspension cable, and the swing arm can all achieve length expansion and contraction. One end of the suspension cable is connected to the lifting lug on the column, and the other end is connected to the swing arm. There is a pin hole at one end of the swing arm. However, this device needs to be assembled on-site during use and disassembled after use, with poor usability, and continuous position adjustment is required during use, resulting in a poor replacement efficiency of the lining plate.

[0005] During the installation process of magnetic lining plates, there are likely to be gaps between adjacent magnetic lining plates. When the gaps are too large, it will affect the ball milling effect of the ball mill. The magnetic lining plates are also prone to collision and damage during installation. If the residues of the damaged magnetic lining plates are not cleaned in time, it will also affect the installation effect of the magnetic lining plates. Moreover, when installing magnetic lining plates, it is difficult to accurately control the gaps between them. When the gaps between the magnetic lining plates are too large or the magnetic lining plates are installed obliquely, it will have an adverse impact on the subsequent grinding of the ball mill. In addition, the collision between the magnetic lining plates and the grinding balls is likely to cause damage to the skewed magnetic lining plates. To solve these problems, we propose the following technical solutions. Summary of the Invention

Detailed implementation manners

[0033] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0034] Embodiment 1

[0035] As Figures 1 to 5 shown, a ball mill liner replacement device includes a moving component 1 and a ball mill sleeve 3. An installation vertical plate 2 is provided at the top of the moving component 1. An auxiliary placement component 4 is provided on the side of the installation vertical plate 2 close to the ball mill sleeve 3. A feeding component 5 is provided at the side end of the auxiliary placement component 4. A magnetic liner 7 is provided on the inner wall of the ball mill sleeve 3, and a positioning plate 8 is also provided on the inner wall of the ball mill sleeve 3. The moving component 1 is used to move the device conveniently, the feeding component 5 is used to transport the magnetic liner 7, and the positioning plate 8 is used to assist in positioning when the magnetic liner 7 is installed.

[0036] The feeding component 5 includes a liner slideway 501 and a transportation component 6. An inner baffle 503 is provided on the side of the liner slideway 501 close to the first rotating rod 401. The magnetic liner 7 slides on the liner slideway 501. The transportation component 6 is used to provide power for the movement of the magnetic liner 7, and the inner baffle 503 is used to limit the position of the magnetic liner 7 when it slides on the liner slideway 501.

[0037] The auxiliary placement component 4 further includes a first hydraulic cylinder 408. The first hydraulic cylinder 408 is provided on the side of the installation vertical plate 2 close to the ball mill sleeve 3. The output end of the first hydraulic cylinder 408 is provided with a first telescopic rod 409. The first hydraulic cylinder 408 provides power for the movement of the first telescopic rod 409.

[0038] The feeding assembly 5 further includes a connecting rod 504. The connecting rod 504 is arranged at the side end of the first telescopic rod 409. A connecting plate 505 is provided at the bottom end of the connecting rod 504. The lining plate slideway 501 is arranged below the connecting plate 505. The transportation assembly 6 is also arranged below the connecting plate 505. The transportation assembly 6 is aligned with the lining plate slideway 501. An outer baffle 506 is provided on the side of the lining plate slideway 501 away from the first rotating rod 401. The magnetic lining plate 7 is moved onto the lining plate slideway 501 with the assistance of the transportation assembly 6, and then the magnetic lining plate 7 slides onto the installation position on the lining plate slideway 501. The outer baffle 506 is used for limiting the movement of the magnetic lining plate 7. The movement of the first telescopic rod 409 drives the movement of the feeding assembly 5 through the connecting rod 504.

[0039] The transportation assembly 6 includes a conveying wheel 601. The conveying wheel 601 is rotatably arranged at the side end of the support plate 603. The support plate 603 is arranged at the bottom end of the connecting plate 505. A conveyor belt 602 is sleeved on the outer end of the conveying wheel 601. A second driving motor 604 is provided on the side of the support plate 603 away from the conveying wheel 601. The output end of the second driving motor 604 is connected to the conveying wheel 601. The second driving motor 604 drives the rotation of the conveying wheel 601. The rotation of the conveying wheel 601 makes the conveyor belt 602 rotate in a cycle. The cyclic rotation of the conveyor belt 602 moves the magnetic lining plate 7 on the conveyor belt 602.

[0040] The moving assembly 1 includes a bottom plate 101. A plurality of universal belt brake wheels 102 are provided at the bottom end of the bottom plate 101. The mounting vertical plate 2 is arranged at the top end of the side of the bottom plate 101 close to the ball mill sleeve 3. A counterweight 103 is provided at the top end of the bottom plate 101 on the side away from the mounting vertical plate 2. The equipment can be conveniently moved and stopped through the universal belt brake wheels 102 at the bottom end of the bottom plate 101, and the counterweight 103 is used to keep the equipment balanced, making the equipment more convenient and stable during use.

[0041] When the device is in use, when the ball mill sleeve 3 installs a new magnetic lining plate 7 after disassembling and cleaning the magnetic lining plate 7, the equipment is moved to a suitable position of the ball mill sleeve 3 through the universal belt brake wheels 102 at the bottom end of the bottom plate 101, so that the auxiliary placement assembly 4 enters the ball mill sleeve 3. The first hydraulic cylinder 408 is started. The movement of the first hydraulic cylinder 408 drives the movement of the first telescopic rod 409. The movement of the first telescopic rod 409 adjusts the position of the feeding assembly 5, so that the lining plate slideway 501 is aligned with the placement position of the magnetic lining plate 7.

[0042] When the magnetic liner 7 is installed, after adjusting the position of the magnetic liner 7, it is placed on the conveyor belt 602. The second driving motor 604 is started, and the second driving motor 604 drives the rotation of the conveyor wheel 601. The rotation of the conveyor wheel 601 causes the conveyor belt 602 to rotate in a cycle, so that the magnetic liner 7 moves into the liner slideway 501. When the magnetic liner 7 moves against the outer baffle 506, the magnetic liner 7 slides on the liner slideway 501 under the action of gravity. During the sliding process of the magnetic liner 7, the outer baffle 506 and the inner baffle 503 cooperate to limit the sliding direction of the magnetic liner 7, so that the magnetic liner 7 slides to the inner wall of the ball mill sleeve 3 for adsorption and installation.

[0043] At the same time, when the subsequent magnetic liners 7 are installed by sliding down, the subsequent magnetic liners 7 are installed one by one with the installed magnetic liners 7 as the limit. And for each installed magnetic liner 7, the ball mill sleeve 3 rotates a corresponding angle to prepare for the installation of the next magnetic liner 7. After the ball mill sleeve 3 rotates one circle, the first hydraulic cylinder 408 retracts a corresponding distance for the installation of the magnetic liners 7 in the next circle.

[0044] During the use of the equipment, the counterweight 103 on the bottom plate 101 is used to assist in keeping the equipment balanced, improving the stability of the equipment during use.

[0045] Embodiment 2

[0046] Based on the ball mill liner replacement device of the above-mentioned Embodiment 1, although this device can realize semi-automation of the installation of the magnetic liner 7 and does not require manual entry into the interior of the ball mill sleeve 3 for installation, ensuring safety. However, during the specific use of this equipment, during the installation of the magnetic liner 7, there is likely to be a gap between adjacent magnetic liners 7, and the existence of the gap is not conducive to the subsequent use of the ball mill. During the sliding process of the magnetic liner 7, the impact between the magnetic liners 7 will also cause damage to the magnetic liner 7, thus affecting the subsequent use of the ball mill. And the sliding installation of the magnetic liner 7 will also cause the position of the positioning plate 8 to shift, making the installation accuracy of the subsequent magnetic liners 7 worse. In addition, the residue remaining after the inner wall of the ball mill sleeve 3 is cleaned will also affect the installation of the magnetic liner 7. To solve these problems, the following technical solutions are proposed:

[0047] As Figures 1 to 8A ball mill lining replacement device shown, the auxiliary placement component 4 includes a first rotating rod 401 and a second rotating rod 405. A push plate 402 is provided on the outer side of the first rotating rod 401. A distance sensor 403 is provided on the side of the push plate 402 away from the feeding component 5. A pressing plate 404 is provided on the side of the push plate 402 away from the first rotating rod 401. The first rotating rod 401 and the second rotating rod 405 are connected by a reducer. A fan blade 406 is provided on the outer side of the second rotating rod 405. A cleaning sleeve 407 is provided on the side of the fan blade 406 away from the second rotating rod 405. The distance sensor 403 is used to detect the distance between the pressing plate 404 and the bottom of the groove. The push plate 402 is used to assist in the installation of the magnetic lining 7. The rotation of the second rotating rod 405 drives the rotation of the fan blade 406. The rotation of the fan blade 406 drives the rotation of the cleaning sleeve 407. The rotation of the fan blade 406 generates wind force at the same time. The rotation of the second rotating rod 405 drives the rotation of the first rotating rod 401 through the reducer. The rotation of the first rotating rod 401 causes the push plate 402 to rotate. The rotation of the cleaning sleeve 407 is used to pre-clean the residue at the installation position of the magnetic lining 7.

[0048] A trapezoidal plate 502 is provided on the side of the lining slideway 501 away from the auxiliary placement component 4. The trapezoidal plate 502 is used to assist in pressing the installed magnetic lining 7.

[0049] A second hydraulic cylinder 410 is provided at the bottom end of the first telescopic rod 409. A second telescopic rod 411 is provided at the output end of the second hydraulic cylinder 410. A cross plate 412 is provided at the bottom end of the second telescopic rod 411. The second hydraulic cylinder 410 drives the lifting of the second telescopic rod 411. The lifting of the second telescopic rod 411 is used to adjust the height of the cleaning sleeve 407.

[0050] A first connecting frame 413 and a second connecting frame 414 are provided on the side of the cross plate 412 away from the second hydraulic cylinder 410. The first rotating rod 401 is rotatably arranged at the side end of the first connecting frame 413. The second rotating rod 405 is rotatably arranged at the side end of the second connecting frame 414.

[0051] A first driving motor 415 is provided on the side of the second connecting frame 414 away from the first connecting frame 413. The output end of the first driving motor 415 rotates through the second connecting frame 414. The output end of the first driving motor 415 is connected to the second rotating rod 405. The first driving motor 415 drives the rotation of the second rotating rod 405.

[0052] A groove is provided on the side of the push plate 402 away from the first rotating rod 401. The pressing plate 404 is located in the groove. The pressing plate 404 is connected to the push plate 402 through a spring 416. The side of the pressing plate 404 away from the push plate 402 is set to be arc-shaped. When the push plate 402 rotates, the pressing plate 404 presses down on the inner baffle 503. The downward movement of the inner baffle 503 causes the trapezoidal plate 502 to move downward to press the previous row of magnetic linings 7 tightly. The spring 416 is used for buffering.

[0053] The fan blade 406 is set in an inclined state, and cleaning brushes are arranged on the outer side of the cleaning sleeve 407. The two sides of the cleaning sleeve 407 do not contact the first connecting frame 413 and the second connecting frame 414, so as to avoid the rotation of the cleaning sleeve 407 being affected by the first connecting frame 413 and the second connecting frame 414.

[0054] Laser distance sensors are arranged on both sides of the first telescopic rod 409. A controller is arranged on one side of the installation vertical plate 2 close to the counterweight 103. The controller is electrically connected to the laser distance sensors, the first driving motor 415, the second driving motor 604, the first hydraulic cylinder 408 and the second hydraulic cylinder 410. The distance sensor 403 transmits data to the controller through wireless signals. The controller is used to coordinate the operation of the equipment.

[0055] When the device is in use, when the magnetic lining 7 is disassembled and cleaned and a new magnetic lining 7 is installed in the ball mill sleeve 3, the equipment enters the ball mill through the assistance of the laser distance sensor to align with the center of the ball mill. The first hydraulic cylinder 408 is started, and the movement of the first hydraulic cylinder 408 drives the movement of the first telescopic rod 409. The movement of the first telescopic rod 409 adjusts the position of the feeding assembly 5, so that the lining slideway 501 is aligned with the placement position of the magnetic lining 7. After the positioning plate 8 on the inner wall of the ball mill sleeve 3 is fixed, if the positioning plate 8 is in a skewed state, it will affect the installation effect of the magnetic lining 7. At this time, the second hydraulic cylinder 410 is started to lift and lower the second telescopic rod 411, thereby adjusting the height of the pressing plate 404. The first driving motor 415 is started, and the first driving motor 415 drives the rotation of the first rotating rod 401 through the second rotating rod 405 and the reducer, so that the pressing plate 404 at the top of the push plate 402 leans against the side end of the positioning plate 8. At this time, the first hydraulic cylinder 408 is started to move the first telescopic rod 409. The movement of the first telescopic rod 409 drives the movement of the pressing plate 404 through devices such as the second hydraulic cylinder 410, the cross plate 412, the first connecting frame 413 and the second connecting frame 414, so that the pressing plate 404 moves along the positioning plate 8. When the installation of the positioning plate 8 is skewed, due to the retraction and extension of the pressing plate 404, the detection value of the distance sensor 403 will change with the movement of the pressing plate 404. When the distance detection value of the distance sensor 403 decreases, the positioning plate 8 is in the direction close to the push plate 402. When the distance detection value of the distance sensor 403 increases, the positioning plate 8 is in the direction away from the push plate 402. Workers can adjust the installation of the positioning plate 8 according to the change of the detection value of the distance sensor 403, so that the subsequent installation of the magnetic lining 7 is more accurate, improving the convenience and accuracy of the equipment use. And when the magnetic lining 7 is installed subsequently, after the ball mill sleeve 3 rotates one circle, when the pressing plate 404 contacts the positioning plate 8, the detection value of the distance sensor 403 remains constant, indicating that the direction of the positioning plate 8 has not been skewed.

[0056] After the preparatory work before the installation of the magnetic liner 7 is completed, the second hydraulic cylinder 410 is started. The second hydraulic cylinder 410 drives the lifting of the second telescopic rod 411, so that the position of the push plate 402 is adapted to the liner slideway 501. During the process of the magnetic liner 7 sliding down along the liner slideway 501, the magnetic liner 7 first contacts the buffer cotton at the side end of the push plate 402 for buffering. Then, the first driving motor 415 is started. The first driving motor 415 drives the rotation of the first rotating rod 401 through the second rotating rod 405 and the speed reducer. The rotation of the first rotating rod 401 drives the rotation of the push plate 402. The rotation of the push plate 402 slowly releases the sliding of the magnetic liner 7, so that the magnetic liner 7 is stably installed on the inner wall of the ball mill sleeve 3. And as the first rotating rod 401 rotates, the subsequent push plate 402 pushes and presses the magnetic liner 7, so that the magnetic liner 7 is closely attached to the positioning plate 8. During the process of pressing the magnetic liner 7, the pressing plate 404 will retract. When the detected value of the distance sensor 403 is less than the threshold value, it indicates that the installation and pressing of the magnetic liner 7 have been completed. At this time, the controller controls the ball mill sleeve 3 to rotate to the installation position of the next magnetic liner 7 for the reinstallation of the magnetic liner 7.

[0057] During the installation process of the magnetic liner 7, the protruding mud blocks on the inner wall of the ball mill sleeve 3 are likely to affect the installation effect of the magnetic liner 7. During the process of the first driving motor 415 driving the second rotating rod 405 to rotate, the rotation of the second rotating rod 405 drives the rotation of the fan blade 406. The rotation of the fan blade 406 generates a wind force effect. The rotation of the fan blade 406 drives the rotation of the cleaning sleeve 407. The rotation of the cleaning sleeve 407 grinds and cleans the mud blocks on the inner wall of the ball mill sleeve 3 that are difficult to clean through the cleaning brush on the outside of the cleaning sleeve 407. After the mud blocks are cleaned into powder, they are discharged under the action of the wind force of the fan blade 406, so as to pre-clean the installation position of the magnetic liner 7 and make the subsequent installation effect of the magnetic liner 7 better.

[0058] When installing the next circle of magnetic liners 7 after completing one circle of installation of the magnetic liners 7 on the inner wall of the ball mill sleeve 3, in order to reduce the gap between each circle of magnetic liners 7 and make it compact, the rotation of the first rotating rod 401 drives the rotation of the push plate 402. As the push plate 402 rotates, the pressing plate 404 outside the push plate 402 presses on the upper end of the inner baffle 503 of the liner slideway 501. As the push plate 402 rotates, the inner baffle 503 is pressed downward and displaced, causing the trapezoidal plate 502 to displace towards the inner wall of the ball mill sleeve 3. The displacement of the trapezoidal plate 502 acts on the previous circle of magnetic liners 7 through the inclined surface of the trapezoidal plate 502, thereby pressing the magnetic liners 7 along the direction of the positioning plate 8. During the pressing process of the magnetic liners 7, the detected value of the distance sensor 403 corresponds to the pressing degree of the magnetic liners 7, ensuring that the gap between each circle of magnetic liners 7 is compact, making the installation of the magnetic liners 7 meet the standard requirements, and improving the stability of equipment use. When the pressing plate 404 presses on the inner baffle 503, it is buffered by the spring 416, thereby protecting the push plate 402. And as the push plate 402 rotates, when the pressing plate 404 passes through the positioning plate 8, the pressing plate 404 passes smoothly through the positioning plate 8 through the buffering of the spring 416, and the retraction distance of the pressing plate 404 is detected by the distance sensor 403, corresponding to reflecting the position information of the positioning plate 8 to judge whether the positioning plate 8 is skewed.

[0059] The present invention improves the convenience of equipment use and the accuracy of installation by setting the liner slideway 501, the push plate 402, the distance sensor 403, the fan blade 406, the first driving motor 415 and the cleaning sleeve 407, and through the mutual configuration among the liner slideway 501, the push plate 402, the distance sensor 403, the fan blade 406, the first driving motor 415 and the cleaning sleeve 407, enabling the equipment to calibrate the positioning plate 8, press the magnetic liners 7 vertically and along the direction of the positioning plate 8 during installation, and pre-clean the installation position of the magnetic liners 7.

[0060] The installation method, connection method or setting method of a ball mill liner replacement device of the present invention are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out.
