Description

Technical Field

[0001] The invention belongs to the technical field of ball mills, and in particular relates to an iron surface slag ball milling device and a use method thereof. Background Art

[0002] Steel slag is a by-product of steelmaking and other production processes. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, from which a large amount of metallic iron and other useful elements can be recovered; the other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0003] In the process of steel slag recycling, it mainly needs to go through the steps of crushing, magnetic separation, ball milling, roller screening, etc. Among them, ball milling mainly refers to the surface grinding of the magnetically separated iron-containing fragments to remove slag and other particles on the surface to obtain cleaner iron, which is convenient for subsequent recycling steps.

[0004] Since the ball mill can still rotate freely when it is stopped, if it rotates during loading and unloading, repair and maintenance, it will have serious and dangerous consequences; therefore, the present invention combines the commonly used manual support rod locking method and proposes a support device that can automatically lock and unlock. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes an iron surface slag ball milling equipment and a method of using the same. Since the ball mill vibrates greatly during use, in order to extend its service life, soft connection and soft start can be selected for driving. However, since the mass and inertia of the ball mill drum are very large, if forced braking is performed when shutting down, it will face a large impact. Therefore, the power supply is generally cut off directly, and the rotation speed is waited to drop naturally. After it drops to a certain level, it is locked. The asynchronous driving problems of the two actuators, how to resist the impact force, and how to lock at the right time are all problems faced by this solution in actual implementation.

[0006] In order to solve the above problems, the present invention creatively proposes an asynchronous dual-mode drive mechanism and a ratchet-type one-way follower assembly, and uses a soft-start assembly to divert power to the ball mill drum and the pushing assembly, thereby achieving a technical contradiction in which the two cannot be connected to each other (the pushing assembly must be started before the ball mill drum to complete the unlocking before the ball mill drum rotates), but cannot be separated from each other (if the two are separated, after the power supply of the drive motor is cut off, the driven disk will rotate with the starting disk body through the twisted connecting belt. Although the connecting belt is designed to be twisted, continuous twisting will greatly reduce the service life of the connecting belt).

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes an iron surface slag ball milling equipment, including a rolling ball milling mechanism, an asynchronous dual-mode driving mechanism, a ratchet-type one-way follower assembly and an adaptive support locking assembly, the rolling ball milling mechanism includes a main body bottom plate and a rotating ball milling assembly, and the rotating ball milling assembly is arranged on the main body bottom plate.

[0008] Furthermore, the rotating ball mill assembly includes a ball mill bracket, a support bearing and a ball mill roller, the ball mill bracket is arranged on the main body bottom plate, the support bearing is clamped in the ball mill bracket, the ball mill roller is clamped in the support bearing, the outside of the ball mill roller is provided with a support ring, and the support ring is evenly distributed with support blades in an annular shape.

[0009] By supporting the support blades evenly distributed in an annular shape on the support collar, the rotation angle of the ball mill drum can be locked quickly and conveniently, thereby avoiding the danger caused by the free rotation of the ball mill drum during loading and unloading, maintenance and other operations.

[0010] Furthermore, the asynchronous dual-mode driving mechanism includes a driving component, a soft-start component and a pushing component. The driving component is arranged on the bottom plate of the main body, the soft-start component is arranged on the driving component, and the pushing component is arranged on the driving component.

[0011] Preferably, the driving assembly comprises a driving motor, a driving spindle and a coupling. The driving motor is arranged on a main body bottom plate, and an output shaft of the driving motor and the driving spindle are connected via a coupling.

[0012] Through the drive motor used to drive the ball mill drum to rotate, adaptive drive and adaptive control of locking and unlocking are achieved only through an ingenious mechanical linkage structure, without any independent electronic drive control module.

[0013] As a further preferred embodiment of the present invention, the soft start assembly includes a start disk connector, a start disk body, a driven disk and a connecting belt, the start disk connector is arranged on the driving main shaft, the start disk body is snap-fitted on the start disk connector, the driven disk is arranged on the belt support assembly, and the connecting belt is evenly distributed in an annular manner between the start disk body and the driven disk.

[0014] By connecting the belt to make a soft connection between the starting disk body and the driven disk, not only can the soft connection have a good advantage in isolating vibrations, but also the time difference during starting can be used to avoid the jamming problem that is easily caused when the ball mill drum and the push assembly are started at the same time.

[0015] As a further preferred embodiment of the present invention, the pushing assembly includes a pushing blade, a pushing sleeve and a linkage plate, the pushing blade is fixedly connected to the end of the driving main shaft, the pushing sleeve is slidably arranged on the driving main shaft, the pushing sleeve is arranged on the linkage plate, and the driving main shaft can rotate in the pushing sleeve.

[0016] When the push blade rotates, it can apply thrust to the push sleeve by stirring the liquid, thereby causing the anti-vibration support assembly to move laterally. The magnitude of this thrust is related to the rotation speed of the push blade during use.

[0017] Furthermore, the ratchet-type one-way follower assembly comprises a belt support assembly and a ratchet assembly, wherein the belt support assembly is arranged on the main body bottom plate, and the ratchet assembly is arranged in the belt support assembly.

[0018] Preferably, the belt support assembly includes a pulley bracket, a driving pulley, a driven pulley and a transmission belt, the pulley bracket is arranged on the main body bottom plate, the driving pulley is rotatably arranged in the pulley bracket, the starting disk body is fixed to the side of the driving pulley, the starting disk body and the driving pulley are coaxially arranged, the driven pulley is clamped on the ball mill drum, and the driving pulley and the driven pulley are transmitted by a transmission belt.

[0019] By means of belt transmission, vibration can be reduced on the one hand, and the rotational motion of the driving end can be decelerated on the other hand, thereby driving the ball mill drum at a lower speed and greater torque.

[0020] As a further preferred embodiment of the present invention, the ratchet assembly includes an inner driving wheel, a movable ratchet, a ratchet elastic ring and an outer ratchet, the inner driving wheel is engaged with the driving main shaft, the movable ratchet is rotatably arranged on the inner driving wheel, the movable ratchet is evenly distributed in a ring shape with several groups, the ratchet elastic ring is arranged between the movable ratchet and the inner driving wheel, the outer ratchet is fixed to the inside of the driving pulley, and the inner ring of the outer ratchet is evenly distributed with ratchet portions corresponding to the movable ratchet.

[0021] Through the cooperation of the movable ratchet and the external ratchet, on the one hand, a speed difference between the driving spindle and the driven disk can be allowed during the startup phase, so that the ball mill drum can be unlocked before it rotates by pushing the blades first to avoid jamming; on the other hand, during the drive disconnection phase, the driving spindle can be rotated synchronously with the rotation of the ball mill drum, which can not only avoid long-term distortion of the connecting belt, but also avoid pushing the blades to stop prematurely and locking the ball mill drum too early (with a large impact).

[0022] Further, the adaptive support locking assembly includes an elastic positioning assembly and an anti-seismic support assembly, the elastic positioning assembly includes a spring mounting seat, a return spring, a locking pin elastic ring, a positioning pin and a positioning seat, the spring mounting seat is fixedly connected to the main body bottom plate, the return spring is arranged between the spring mounting seat and the linkage plate, the locking pin elastic ring is arranged at the bottom of the linkage plate, the positioning pin is arranged on the locking pin elastic ring, the positioning seat is fixedly connected to the main body bottom plate, the positioning seat is provided with a groove portion matching the positioning pin, and the anti-seismic support assembly is arranged on the main body bottom plate.

[0023] Through the elastic deformation of the locking pin elastic ring and the jumping of the positioning pin, the positioning pin can be pushed to slide from one groove part to another groove part only when the lateral thrust reaches a certain level, thereby achieving the technical purpose of rapid locking and unlocking and avoiding the slow sliding of the guide slider.

[0024] Preferably, the anti-seismic support assembly includes a guide rail, a guide slider, a sliding strut, a telescopic strut and an anti-seismic spring, the guide rail is arranged on the bottom plate of the main body, the guide slider is snap-fitted and slidably arranged on the guide rail, the sliding strut is arranged on the guide slider, the telescopic strut is snap-fitted and slidably arranged in the sliding strut, the guide slider is symmetrically arranged at both ends of the linkage plate, and the anti-seismic spring is arranged between the sliding strut and the telescopic strut.

[0025] This solution also discloses a method for using an iron surface slag ball mill, which mainly includes the following steps:

[0026] Step 1: Load the abrasive and target material into the ball mill drum, and then start the driving motor. In the early stage when the driving motor rotates the driving spindle, since the driving pulley and the driven pulley are softly connected by the transmission belt, before the driven pulley starts to rotate, the driving pulley will follow the driving spindle to rotate a certain angle. Since the greater the rotation speed of the driving spindle, the stronger the thrust that the push blade can generate, before the driven pulley starts to rotate, the push sleeve has already overcome the elastic force of the reset spring under the rotation of the push blade to slide. Through the matching of the positioning pin and the groove part, the positioning pin has the tendency to stay at the position where the groove part is located. Only when the thrust or reset elastic force is large enough, will it leave the current groove part and slide to the next groove part;

[0027] Step 2: When the driven disk does not start to rotate, the driving spindle rotates with the inner driving wheel and the movable ratchet. At this time, due to the matching relationship between the movable ratchet and the ratchet part, the rotation of the inner driving wheel does not rotate the outer ratchet and the driven disk;

[0028] Step 3: Because the push sleeve and the linkage plate slide, the guide slider also slides with the sliding support rod. Therefore, when the driven plate rotates with the driven pulley and the ball mill drum through the active pulley, the telescopic support rod has left the supporting blade by its own sliding. After the telescopic support rod loses the limit of the supporting blade, the rotation of the driven plate will drive the ball mill drum to continue to rotate. During the rotation of the ball mill drum, the internal materials can be ground.

[0029] Step 4: After grinding is completed, disconnect the power supply of the drive motor and stop the machine. At this time, the ball mill drum continues to rotate and gradually slows down under the action of inertia. At this time, the rotation of the driven disc can continue to rotate with the inner drive wheel and the drive spindle through the outer ratchet. Therefore, although the drive motor has no driving force, the connecting belt will not be continuously twisted as it was at startup;

[0030] Step 5: As the speed of the ball mill drum decreases, the thrust of the push blade on the push sleeve also decreases until the positioning pin overcomes the elastic force of the locking pin elastic ring, retracts, and slides to the next groove portion.

[0031] The beneficial effects achieved by the present invention using the above structure are as follows:

[0032] (1) By supporting the support blades evenly distributed in an annular pattern on the support ring, the rotation angle of the ball mill drum can be locked quickly and conveniently, thereby avoiding the danger caused by the free rotation of the ball mill drum during loading and unloading, maintenance and other operations.

[0033] (2) Through the drive motor used to drive the ball mill drum to rotate, adaptive drive and adaptive control of locking and unlocking are achieved simply through an ingenious mechanical linkage structure without any independent electronic drive control module.

[0034] (3) By connecting the belt to make a soft connection between the starting disk body and the driven disk, not only can the soft connection have a good isolation effect on vibration, but also can avoid the jamming problem that is easily caused when the ball mill drum and the push assembly are started at the same time by the time difference during starting.

[0035] (4) When the push blade rotates, it can apply thrust to the push sleeve by stirring the liquid, thereby causing the anti-seismic support assembly to move laterally. The magnitude of this thrust is related to the rotation speed of the push blade during use.

[0036] (5) Belt drive can reduce vibration on the one hand and decelerate the rotational motion of the drive end on the other hand, thereby driving the ball mill drum at a lower speed and greater torque.

[0037] (6) Through the cooperation of the movable ratchet and the external ratchet, on the one hand, a speed difference between the driving spindle and the driven disc can be allowed during the startup phase, so that the ball mill drum can be unlocked before it rotates by pushing the blades first to avoid jamming; on the other hand, during the drive disconnection phase, the driving spindle can be rotated synchronously with the rotation of the ball mill drum, which can not only avoid the long-term distortion of the connecting belt, but also avoid the pushing blades stopping prematurely and locking the ball mill drum too early (with a large impact).

[0038] (7) Through the elastic deformation of the locking pin elastic ring and the jumping of the positioning pin, the positioning pin can be pushed to slide from one groove part to another groove part only when the lateral thrust reaches a certain level, thereby achieving the technical purpose of rapid locking and unlocking and avoiding the slow sliding of the guide slider.

[0056] like Figure 1 to Figure 13 As shown, the present invention proposes an iron surface slag ball milling device, including a rolling ball milling mechanism 1, an asynchronous dual-mode driving mechanism 2, a ratchet-type one-way follower assembly 3 and an adaptive support locking assembly 4, the rolling ball milling mechanism 1 includes a main body bottom plate 5 and a rotating ball milling assembly 6, and the rotating ball milling assembly 6 is arranged on the main body bottom plate 5.

[0057] The rotating ball mill assembly 6 includes a ball mill bracket 7, a support bearing 8 and a ball mill drum 9. The ball mill bracket 7 is arranged on the main body bottom plate 5, the support bearing 8 is clamped in the ball mill bracket 7, the ball mill drum 9 is clamped in the support bearing 8, and a support ring 10 is provided on the outside of the ball mill drum 9. Support blades 11 are evenly distributed in an annular manner on the support ring 10.

[0058] By supporting the annular support blades 11 evenly distributed on the support ring 10, the rotation angle of the ball mill drum 9 can be locked quickly and conveniently, thereby avoiding the danger caused by the free rotation of the ball mill drum 9 during loading and unloading, maintenance and other operations.

[0059] The asynchronous dual-mode driving mechanism 2 includes a driving component 12 , a soft-starting component 13 and a pushing component 14 . The driving component 12 is arranged on the main body bottom plate 5 , the soft-starting component 13 is arranged on the driving component 12 , and the pushing component 14 is arranged on the driving component 12 .

[0060] The driving assembly 12 includes a driving motor 15 , a driving spindle 16 and a coupling 17 . The driving motor 15 is disposed on the main body bottom plate 5 , and the output shaft of the driving motor 15 and the driving spindle 16 are connected via the coupling 17 .

[0061] By means of the driving motor 15 for driving the ball mill drum 9 to rotate, adaptive driving and adaptive control of locking and unlocking are achieved only through an ingenious mechanical linkage structure without any independent electronic drive control module.

[0062] The soft start assembly 13 includes a start disk connector 18, a start disk body 19, a driven disk 20 and a connecting belt 21. The start disk connector 18 is arranged on the driving main shaft 16, the start disk body 19 is snap-fitted on the start disk connector 18, the driven disk 20 is arranged on the belt support assembly 25, and the connecting belt 21 is evenly distributed in a ring shape between the start disk body 19 and the driven disk 20.

[0063] By connecting the belt 21 to softly connect the starter disc body 19 and the driven disc 20, not only can the soft connection have a good vibration isolation effect, but also can avoid the jamming problem that is easily caused when the ball mill drum 9 and the push assembly 14 are started at the same time due to the time difference during starting.

[0064] The pushing assembly 14 includes a pushing blade 22 , a pushing sleeve 23 and a linkage plate 24 . The pushing blade 22 is fixedly connected to the end of the driving main shaft 16 . The pushing sleeve 23 is slidably arranged on the driving main shaft 16 . The pushing sleeve 23 is arranged on the linkage plate 24 . The driving main shaft 16 can rotate in the pushing sleeve 23 .

[0065] When the push blade 22 rotates, it can apply thrust to the push sleeve 23 by stirring the liquid, thereby causing the anti-vibration support assembly 37 to move laterally. The magnitude of this thrust is related to the rotation speed of the push blade 22 during use.

[0066] The adaptive support locking assembly 4 includes an elastic positioning assembly 36 and an anti-seismic support assembly 37. The elastic positioning assembly 36 includes a spring mounting seat 38, a return spring 39, a locking pin elastic ring 40, a positioning pin 41 and a positioning seat 47. The spring mounting seat 38 is fixedly connected to the main body bottom plate 5. The return spring 39 is arranged between the spring mounting seat 38 and the linkage plate 24. The locking pin elastic ring 40 is arranged at the bottom of the linkage plate 24. The positioning pin 41 is arranged on the locking pin elastic ring 40. The positioning seat 47 is fixedly connected to the main body bottom plate 5. The positioning seat 47 is provided with a groove portion 48 matching the positioning pin 41. The anti-seismic support assembly 37 is arranged on the main body bottom plate 5.

[0067] Through the elastic deformation of the locking pin elastic ring 40 and the jumping of the positioning pin 41, the positioning pin 41 can be pushed to slide from one groove portion 48 to another groove portion 48 only when the lateral thrust reaches a certain level, thereby achieving the technical purpose of rapid locking and unlocking and avoiding the slow sliding of the guide slider 43.

[0068] The anti-seismic support assembly 37 includes a guide rail 42, a guide slider 43, a sliding strut 44, a telescopic strut 45 and an anti-seismic spring 46. The guide rail 42 is arranged on the main body bottom plate 5, the guide slider 43 is slidably arranged on the guide rail 42, the sliding strut 44 is arranged on the guide slider 43, the telescopic strut 45 is slidably arranged in the sliding strut 44, the guide slider 43 is symmetrically arranged at both ends of the linkage plate 24, and the anti-seismic spring 46 is arranged between the sliding strut 44 and the telescopic strut 45.

[0069] The ratchet type one-way follower assembly 3 comprises a belt support assembly 25 and a ratchet assembly 26 . The belt support assembly 25 is arranged on the main body bottom plate 5 , and the ratchet assembly 26 is arranged in the belt support assembly 25 .

[0070] The belt support assembly 25 includes a pulley bracket 27, a driving pulley 28, a driven pulley 29 and a transmission belt 30. The pulley bracket 27 is arranged on the main body bottom plate 5. The driving pulley 28 is rotatably arranged in the pulley bracket 27. The starting disk body 19 is fixed to the side of the driving pulley 28. The starting disk body 19 and the driving pulley 28 are coaxially arranged. The driven pulley 29 is engaged with the ball mill drum 9. The driving pulley 28 and the driven pulley 29 are transmitted through the transmission belt 30.

[0071] By means of belt transmission, vibration can be reduced on the one hand, and the rotational motion of the driving end can be decelerated on the other hand, so that the ball mill drum 9 can be driven at a lower rotation speed and a greater torque.

[0072] The ratchet assembly 26 includes an inner driving wheel 31, a movable ratchet 32, a ratchet elastic ring 33 and an outer ratchet 34. The inner driving wheel 31 is engaged with the driving main shaft 16, and the movable ratchet 32 ​​is rotatably arranged on the inner driving wheel 31. The movable ratchet 32 ​​is evenly distributed in a ring shape in a number of groups. The ratchet elastic ring 33 is arranged between the movable ratchet 32 ​​and the inner driving wheel 31. The outer ratchet 34 is fixed to the inside of the active pulley 28, and the inner ring of the outer ratchet 34 is evenly distributed with ratchet parts 35 corresponding to the movable ratchet 32.

[0073] Through the cooperation of the movable ratchet 32 ​​and the outer ratchet 34, on the one hand, a speed difference between the driving spindle 16 and the driven disk 20 can be allowed during the startup phase, so that the ball mill 9 can be unlocked before it rotates by pushing the blade 22 to avoid jamming. On the other hand, when the drive is disconnected, the driving spindle 16 can be rotated synchronously with the rotation of the ball mill 9, which can not only avoid the long-term distortion of the connecting belt 21, but also avoid the pushing blade 22 from stopping early and locking the ball mill 9 too early (with a large impact).

[0074] When in use, the user first needs to load the abrasive and the target material into the ball mill drum 9, and then start the drive motor 15. In the initial stage when the drive motor 15 rotates the drive spindle 16, since the driving pulley 28 and the driven pulley 29 are softly connected by the transmission belt 30, before the driven pulley 29 starts to rotate, the driving pulley 28 will first rotate a certain angle following the drive spindle 16. Since the greater the rotation speed of the drive spindle 16, the stronger the thrust that the push blade 22 can generate, before the driven pulley 29 starts to rotate, the push sleeve 23 has already overcome the elastic force of the return spring 39 under the rotation push of the push blade 22 and slides. Through the matching of the positioning pin 41 and the groove portion 48, the positioning pin 41 has a tendency to stay at the position where the groove portion 48 is located. Only when the thrust or the return elastic force is large enough, will it leave the current groove portion 48 and slide into the next groove portion 48;

[0075] When the driven disk 20 does not start to rotate, the driving spindle 16 rotates the inner driving wheel 31 and the movable ratchet 32. At this time, due to the matching relationship between the movable ratchet 32 ​​and the ratchet portion 35, the rotation of the inner driving wheel 31 does not rotate the outer ratchet 34 and the driven disk 20.

[0076] Because the push sleeve 23 and the linkage plate 24 slide, the guide slider 43 also slides with the sliding support rod 44. Therefore, when the driven disc 20 rotates with the driven pulley 29 and the ball mill 9 through the driving pulley 28, the telescopic support rod 45 has already left the supporting blade 11 by its own sliding. After the telescopic support rod 45 stops the supporting blade 11, the rotation of the driven disc 20 will drive the ball mill 9 to continue to rotate. During the rotation of the ball mill 9, the material inside can be ground.

[0077] After grinding is completed, the power supply of the driving motor 15 is disconnected and the machine is shut down. At this time, the ball mill drum 9 continues to rotate and gradually slows down under the action of inertia. At this time, the rotation of the driven plate 20 can continue to rotate with the inner driving wheel 31 and the driving spindle 16 through the outer ratchet 34. Therefore, although the driving motor 15 has no driving force, the connecting belt 21 will not be continuously twisted as when it is started;

[0078] As the speed of the ball mill drum 9 decreases, the thrust of the push blade 22 on the push sleeve 23 also decreases, until the positioning pin 41 overcomes the elastic force of the locking pin elastic ring 40 and retracts and slides to the next groove portion 48.

[0079] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0080] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.

7. The method for using the iron surface slag ball mill according to claim 6, characterized in that: The steps include: Step 1: Load the abrasive and target material into the ball mill drum, and then start the driving motor. In the early stage when the driving motor rotates the driving spindle, since the driving pulley and the driven pulley are softly connected by the transmission belt, before the driven pulley starts to rotate, the driving pulley will follow the driving spindle to rotate a certain angle. Since the greater the rotation speed of the driving spindle, the stronger the thrust that the push blade can generate, before the driven pulley starts to rotate, the push sleeve has already overcome the elastic force of the reset spring under the rotation of the push blade to slide. Through the matching of the positioning pin and the groove part, the positioning pin has the tendency to stay at the position where the groove part is located. Only when the thrust or reset elastic force is large enough, will it leave the current groove part and slide to the next groove part; Step 2: When the driven disk does not start to rotate, the driving spindle rotates with the inner driving wheel and the movable ratchet. At this time, due to the matching relationship between the movable ratchet and the ratchet part, the rotation of the inner driving wheel does not rotate the outer ratchet and the driven disk; Step 3: Because the push sleeve and the linkage plate slide, the guide slider also slides with the sliding support rod. Therefore, when the driven plate rotates with the driven pulley and the ball mill drum through the active pulley, the telescopic support rod has left the supporting blade by its own sliding. After the telescopic support rod loses the limit of the supporting blade, the rotation of the driven plate will drive the ball mill drum to continue to rotate. During the rotation of the ball mill drum, the internal materials can be ground. Step 4: After grinding is completed, disconnect the power supply of the drive motor and stop the machine. At this time, the ball mill drum continues to rotate and gradually slows down under the action of inertia. At this time, the rotation of the driven disc can continue to rotate with the inner drive wheel and the drive spindle through the outer ratchet. Therefore, although the drive motor has no driving force, the connecting belt will not be continuously twisted as it was at startup; Step 5: As the speed of the ball mill drum decreases, the thrust of the push blade on the push sleeve also decreases until the positioning pin overcomes the elastic force of the locking pin elastic ring, retracts, and slides to the next groove portion.
