Description

Technical Field

[0001] The present invention relates to the technical field of rotary kiln axis monitoring, and specifically to a device for monitoring the axis state of a lithium ore rotary kiln. Background Technique

[0002] A rotary kiln is a large-scale thermal engineering rotating mechanical device, and the faults of the kiln are closely related to the straightness of its center line. The normal and ideal center line of the kiln is a straight line or a state close to a straight line to ensure uniform stress on the supporting components of the rotary kiln. Due to the long-term continuous low-speed rotary operation of the rotary kiln under harsh working conditions of high temperature, heavy load, and multi-dust, its center line will deviate. When the deviation exceeds the standard range, a series of faults of the rotary kiln will be triggered and even a kiln shutdown accident will occur. Therefore, it is necessary to monitor its axis.

[0003] For example, the utility model patent with the application number CN200720310973.0 discloses a device for monitoring the axis state of a rotary kiln. The device for monitoring the axis state of the rotary kiln of this utility model patent can timely understand and master the operation of the axis of the rotary kiln, and then use the downtime to make timely adjustments to ensure that the axis of the rotary kiln always runs on a straight line. However, when this device is used, due to the usually high temperature and multi-dust operation environment of the rotary kiln, there will be adhered dust on its rollers, resulting in measurement errors.

[0009] Further, a bottom plate is provided on the side of the sliding plate away from the central plate, and a slot is provided on the surface of the bottom plate. A plug rod is slidably connected in the slot, and a clamping groove is provided on the surface of the plug rod. The plug rod is fixed on the sliding plate. The shaft rod is rotatably connected to the bottom plate, and the bidirectional screw rod penetrates through the middle of the bottom plate.

[0010] Further, a clamping cavity is provided on one side of the slot of the bottom plate, and a clamping spring is connected to the clamping cavity. The other end of the clamping spring is connected to a clamping plate, and the clamping plate is elastically connected to the clamping cavity through the clamping spring. The clamping plate is engaged and slidably connected to the bottom plate through the clamping cavity, and the clamping plate is engaged and connected to the plug rod through the clamping groove.

[0011] Further, lifting rods are symmetrically connected to both sides of the bottom plate, and an installation frame is connected above the lifting rod on one side of the bottom plate.

The wedge block is engaged and connected to the support column through the clamping opening.

[0015] The present invention provides a lithium ore rotary kiln axis state monitoring device, which has the following beneficial effects: during use, the axis state of the rotary kiln during operation can be monitored. During the monitoring process, the rollers are dust-removed and lubricated as the rotary kiln rotates, reducing the wear of the rollers. At the same time, the monitoring error caused by dust adhesion is reduced. And during use, the device can be conveniently assembled and adjusted, so as to adapt to rotary kilns with different diameters and inclinations, improving the applicability of the device.

[0016] 1. When the present invention is in use, the scraping plates symmetrically connected to both sides of the support plate can scrape off the dust particles adhering to the surface of the rollers in real time when the rollers rotate with the rotary kiln, avoiding the accumulation of dust layers and affecting the uniformity of the contact pressure between the rollers and the surface of the kiln body. At the same time, the oil tank precisely sprays the lubricant onto the surface of the rollers through the oil spray pipe. The one-way valves arranged in the through holes and the oil spray pipe can ensure the one-way flow of the oil fluid, preventing the oil fluid from flowing back and polluting the oil tank, and also avoiding the intrusion of external dust into the oil injection system. The oil injection action is synchronously linked with the vibration of the rollers: when the rollers drive the support plate to reciprocate due to the vibration of the kiln body, the oil spray pipe expands and contracts in the sleeve, and the periodic supply of lubricant is realized through the change of oil pressure, ensuring the dynamic matching of the lubrication efficiency and the rotational speed of the rollers. In addition, the buffer spring not only plays a role in damping, but the push-pull force tester connected to it can monitor the contact pressure between the rollers and the kiln body in real time, adjust the lubrication frequency through data feedback, further optimize the lubrication effect, realize automatic dust removal and continuous lubrication of the rollers, and effectively solve the measurement errors and component wear problems caused by dust accumulation and insufficient lubrication of traditional contact monitoring devices.

[0017] 2. Through mechanical linkage design, the present invention realizes the rapid adaptation of the device to rotary kilns with different diameters and inclinations, solves the technical bottleneck of complex adjustment and poor adaptability of traditional devices. When in use, the threaded connection structure of the bidirectional screw and the sliding plate, combined with the sliding restriction of the sliding rod on the slider, can realize the synchronous and symmetrical movement of the two sliding plates under the drive of the rocking disc, and precisely adjust the contact distance between the monitoring component and the surface of the rotary kiln. This design not only ensures the uniform pressing of the rollers and the kiln body, but also ensures the transmission stability through the snap-fit sliding connection between the bushing and the shaft rod, avoiding mechanical jamming caused by eccentricity during the adjustment process. In addition, the combined design of the lifting rod and the sliding frame allows the installation frame to be adjusted at multiple angles: when the lifting rod displaces in the sliding frame through the sliding block, the installation frame can rotate around the fulcrum of the other lifting rod, thereby dynamically matching the axis inclination state of the rotary kiln.

[0018] 3. The present invention realizes the rapid disassembly, assembly and stable fixation of the monitoring component, solves the pain points of time-consuming maintenance and easy loosening of connections of traditional devices. When the pillar is inserted into the placement groove of the installation frame through the placement plate, the installation plate undergoes elastic deformation under the action of the installation spring, and uses the inclined plane to guide and press the placement plate into the groove. After the pillar is completely in place, the installation spring rebounds and pushes the installation plate to clamp the placement plate, forming a two-way locking structure. This design does not require bolt fastening, and only needs to press the installation plate to complete the installation or disassembly of the pillar. At the same time, the cooperation between the wedge block and the upper bayonet on the pillar further enhances the connection rigidity of the bracket: after the fixing rod is inserted into the wedge groove, the wedge block and the bayonet form a surface contact through the pre-tightening force of the bolt, effectively dispersing the vibration load and avoiding connection loosening during long-term operation.

Detailed implementation manner

[0026] Please refer to Figures 1 to 6, the present invention provides a technical solution: a lithium ore rotary kiln axis state monitoring device, including a central plate 1 and a monitoring component 2. The monitoring components 2 are symmetrically arranged on both sides of the outside of the central plate 1. The monitoring component 2 includes a bracket 201. The brackets 201 are symmetrically arranged on both sides of the outside of the central plate 1. And two wedges 202 are symmetrically connected to one side of the bracket 201. A wedge groove 203 is formed on the surface of the wedge 202, and a fixing rod 204 is snap-connected in the wedge groove 203. Two oil tanks 205 are symmetrically connected to the other side of the bracket 201. And a through hole 206 is arranged on the surface of the oil tank 205. A buffer spring 207 is symmetrically connected to the side of the oil tank 205 away from the bracket 201. And a sleeve 208 is arranged in the middle of the oil tank 205. A fuel injection pipe 209 is sleeved inside the sleeve 208. And the other side of the fuel injection pipe 209 is connected to a support plate 210. Scraping plates 211 are symmetrically connected to both sides of the support plate 210. And a roller 212 is rotatably connected to one side of the support plate 210.

[0027] Please refer to Figures 1 to 4 , the fixing rod 204 is fixed to the wedge 202 by bolts. The bracket 201 is Y-shaped. The support plate 210 is elastically connected to the oil tank 205 through the buffer spring 207. And a push-pull force tester is connected to the buffer spring 207. Check valves are arranged in both the through hole 206 and the fuel injection pipe 209;

[0028] The specific operation is as follows. When the scraping plates 211 symmetrically connected to both sides of the support plate 210 rotate with the rotary kiln as the roller 212 rotates, they can scrape off the dust particles attached to the surface of the roller in real time, avoiding the accumulation of the dust layer from affecting the uniformity of the contact pressure between the roller and the surface of the kiln body. At the same time, the oil tank 205 accurately sprays the lubricant onto the surface of the roller 212 through the fuel injection pipe 209. The check valves arranged in the through hole 206 and the fuel injection pipe 209 can ensure the one-way flow of the oil fluid, preventing the oil fluid from flowing back and polluting the oil tank and also avoiding the intrusion of external dust into the fuel injection system. The fuel injection action is synchronously linked with the vibration of the roller: when the roller drives the support plate 210 to reciprocate due to the vibration of the kiln body, the fuel injection pipe 209 expands and contracts in the sleeve 208, and the periodic supply of the lubricant is realized through the change of the oil pressure, ensuring the dynamic matching of the lubrication efficiency and the rotational speed of the roller. In addition, the buffer spring 207 not only plays a role in shock absorption, but the connected push-pull force tester can monitor the contact pressure between the roller and the kiln body in real time, adjust the lubrication frequency through data feedback, further optimize the lubrication effect, realize the automatic dust removal and continuous lubrication of the roller 212, and effectively solve the measurement error and component wear problems caused by dust accumulation and insufficient lubrication of the traditional contact monitoring device.

[0029] Please refer to Figures 1 to 6, sliding rods 3 are symmetrically connected to both sides of the central plate 1, and a bidirectional screw rod 4 is rotatably connected to the middle of the central plate 1. Slide plates 5 are symmetrically threadedly connected to both sides of the bidirectional screw rod 4, and sliders 6 are symmetrically connected to both sides of the slide plates 5. The sliders 6 are engaged and slidably connected to the sliding rods 3. A transmission wheel 7 is arranged in the middle of the bidirectional screw rod 4, and a driving wheel 8 is connected to one side of the transmission wheel 7 through a belt. A sleeve 9 is connected to one side of the driving wheel 8, and a shaft rod 10 is engaged and slidably connected to the inner side of the sleeve 9. One end of the shaft rod 10 away from the sleeve 9 is connected to a rocking disc 11. The sleeve 9 is rotatably connected to the central plate 1. A bottom plate 12 is arranged on the side of the slide plate 5 away from the central plate 1, and a slot 13 is formed on the surface of the bottom plate 12. A plug rod 14 is slidably connected in the slot 13, and a clamping groove 15 is formed on the surface of the plug rod 14. The plug rod 14 is fixed on the slide plate 5. The shaft rod 10 is rotatably connected to the bottom plate 12, and the bidirectional screw rod 4 passes through the middle of the bottom plate 12. A clamping cavity 16 is formed on one side of the bottom plate 12 in the slot 13, and a clamping spring 17 is connected to the clamping cavity 16. The other end of the clamping spring 17 is connected to a clamping plate 18, and the clamping plate 18 is elastically connected to the clamping cavity 16 through the clamping spring 17. The clamping plate 18 is engaged and slidably connected to the bottom plate 12 through the clamping cavity 16, and the clamping plate 18 is engaged and connected to the plug rod 14 through the clamping groove 15. Lifting rods 19 are symmetrically connected to both sides of the bottom plate 12, and an installation frame 20 is connected above the lifting rod 19 on one side of the bottom plate 12. A sliding frame 21 is connected to one side of the installation frame 20, and a sliding block 22 is engaged and slidably connected in the sliding frame 21. The sliding block 22 is rotatably connected to the lifting rod 19. An accommodation groove 23 is formed in the middle of the installation frame 20, and installation grooves 24 are symmetrically formed on both sides of the accommodation groove 23. Installation springs 25 are symmetrically connected in the installation grooves 24, and one end of each installation spring 25 is connected to an installation plate 26. An accommodation plate 27 is arranged in the accommodation groove 23, and a support column 28 is connected to one side of the accommodation plate 27. Clamping openings 29 are symmetrically formed on the upper part of the support column 28. The installation plate 26 is elastically connected to the installation groove 24 through the installation spring 25, and the support column 28 is engaged and connected to the installation frame 20 through the accommodation plate 27, the installation plate 26, and the accommodation groove 23. The wedge block 202 is engaged and connected to the support column 28 through the clamping opening 29;

[0030] The specific operation is as follows: through a mechanical linkage design, the device can quickly adapt to rotary kilns of varying diameters and inclinations, resolving the technical bottlenecks of traditional devices, such as complex adjustment and poor adaptability. During use, the threaded connection between the bidirectional screw 4 and the slide 5, combined with the sliding restriction of the slider 6 by the slide rod 3, enables synchronous and symmetrical movement of the slides 5 on both sides, driven by the rocker 11, to precisely adjust the contact distance between the monitoring assembly 2 and the rotary kiln surface. This design not only ensures uniform compression between the roller 212 and the kiln body, but also, through the interlocking and sliding connection between the sleeve 9 and the shaft 10, ensures transmission stability and avoids mechanical jamming caused by eccentricity during adjustment. Furthermore, the combined design of the lifting rod 19 and the sliding frame 21 allows for multi-angle tilt adjustment of the mounting frame 20: when the lifting rod 19 is displaced within the sliding frame 21 via the sliding block 22, the mounting frame 20 can rotate about the lifting rod fulcrum on the other side, dynamically matching the tilt of the rotary kiln's axis. This enables rapid assembly and disassembly of the monitoring assembly and stable fixation, resolving the time-consuming maintenance and loose connection issues of traditional devices. When the support 28 is inserted into the mounting groove 23 of the mounting frame 20 via the mounting plate 27, the mounting plate 26 undergoes elastic deformation under the action of the mounting spring 25, using the inclined surface to guide the mounting plate 27 into the groove. Once the support 28 is fully in place, the mounting spring 25 rebounds, pushing the mounting plate 26 to clamp the mounting plate 27, forming a bidirectional locking structure. This design eliminates the need for bolt tightening; simply pressing the mounting plate 26 completes the installation or removal of the support 28. At the same time, the cooperation between the wedge block 202 and the bayonet 29 on the pillar 28 further enhances the connection rigidity of the bracket 201: after the fixing rod 204 is inserted into the wedge groove 203, the wedge block 202 and the bayonet 29 form surface contact through the pre-tightening force of the bolt, effectively dispersing the vibration load and avoiding loose connection during long-term operation.

[0031] In summary, when using the lithium ore rotary kiln axis state monitoring device, first place the center plate 1 and the slide plate 5 under the rotary kiln, so that the center line of the center plate 1 is located directly below the center line of the rotary kiln and fix the center plate 1, and then install the bottom plate 12 on the slide plate 5. When installing the bottom plate 12, first pass the bottom plate 12 through the bidirectional screw 4, and insert the plug rod 14 into the slot 13. The plug rod 14 is pressed by the inclined surface of the clamping plate 18 to slide in the clamping cavity 16 and compress the clamping spring 17. When the bottom plate 12 is close to the slide plate 5, the clamping plate 18 rebounds under the action of the clamping spring 17 and is inserted into the clamping groove 15, which can restrict the plug rod 14, thereby fixing the bottom plate 12 on the slide plate 5 through the plug rod 14 and the slot 13. When disassembling, you only need to pull the clamping plate 18 to make it disengage from the clamping groove 15, and then you can pull the plug rod 14 out of the slot 13 to complete the disassembly;

[0032] After the skateboard 5 is fixed, the support column 28 is inserted into the placement groove 23. The placement plate 27 enters the placement groove 23 together with the support column 28. It is pressed into the installation groove 24 through the inclined surface on the mounting plate 26, and the installation spring 25 is compressed. After the mounting plate 26 is completely snapped into the placement groove 23, the mounting plate 26 rebounds under the action of the installation spring 25 to restrict the placement plate 27, and then the support column 28 can be fixed on the mounting frame 20. When disassembling, the mounting plate 26 is pressured again to make it slide into the installation groove 24, and the restriction on the placement plate 27 can be released, so that the support column 28 can be removed from the mounting frame 20;

[0033] Then the bracket 201 is assembled onto the support column 28. When installing the bracket 201, first insert the wedge block 202 into the bayonet 29 and make the bracket 201 close to the support column 28. Then insert the fixing rod 204 into the wedge groove 203 and fix the fixing rod 204 with bolts, so that the fixing rod 204 cooperates with the wedge block 202 to fix the bracket 201 on the support column 28;

[0034] After the bracket 201 is installed, the lifting rods 19 on both sides of the center plate 1 drive the mounting frame 20 to lift and tilt the mounting frame 20 by different lifting heights of the lifting rods 19. When the lifting rods 19 are lifted and lowered at different heights, the lifting rods 19 connected to the slider 6 drive the sliding block 22 to move within the sliding frame 21, so that the mounting frame 20 can rotate around the connection with the other lifting rod 19, thereby changing the tilt angle of the mounting frame 20. The sliding frame 21 can maintain the connection with the lifting rod 19 through the sliding block 22, avoiding the deviation of the mounting frame 20 and ensuring the stability of the mounting frame 20, making the axis direction of the roller 212 parallel to the axis direction of the rotary kiln, and making the center line of the bracket 201 and the axis of the rotary kiln on the same horizontal plane;

[0035] After the adjustment of the mounting frame 20 is completed, the turntable 11 can be rotated on the bottom plate 12, so that the turntable 11 drives the sleeve 9 to rotate through the shaft rod 10. Then the driving wheel 8 drives the bidirectional screw 4 to rotate through the transmission wheel 7, so that the skateboard 5 drives the bottom plate 12 to move synchronously and equally spaced on both sides of the center plate 1, and the distance between the skateboard 5 and the center plate 1 is adjusted, making the roller 212 close to and press tightly against the outer wall of the rotary kiln body, so that the roller 212 can compress the buffer spring 207 to a certain extent through the support plate 210, and the data measured by the push-pull force tester connected to the buffer spring 207 reaches a predetermined value. When the skateboard 5 drives the bottom plate 12 to move, the slider 6 can move together with the skateboard 5 and restrict the skateboard 5 through the slide rod 3 to avoid the deviation of the skateboard 5 during the movement. At the same time, the shaft rod 10 slides inside the sleeve 9 along with the bottom plate 12 and maintains the snap connection with the sleeve 9 to ensure that the shaft rod 10 can drive the sleeve 9 to rotate;

[0036] After the roller 212 is pressed against the outer wall of the rotary kiln, start the rotary kiln, and the axial state of the rotary kiln during operation can be monitored. During the monitoring, with the vibration caused by the rotation of the rotary kiln, the roller 212 will be driven to vibrate synchronously. The buffer spring 207 can buffer the vibration to prevent the connections of the device from loosening due to long-term vibration. The push-pull force tester connected to the buffer spring 207 can measure and record the force on the buffer spring 207. If all the measurement data are within the preset value range, it indicates that the axis of the rotary kiln has not shifted. If the measurement data shows a long-term deviation and is outside the preset value range, it means that the roller 212 with a larger measurement data is under excessive pressure during the operation of the rotary kiln, and the axis of the rotary kiln is skewed towards the direction of this roller 212. At this time, the device can send the measurement data to an external device and issue a warning to the operator, reminding the operator to stop the rotary kiln for maintenance in time to avoid excessive losses.

[0037] During the monitoring process, with the vibration of the roller 212, the support plate 210 can drive the oil spray pipe 209 to move reciprocally with the vibration of the roller 212 under the action of the buffer spring 207. Thus, the oil in the oil tank 205 is pumped out and sprayed onto the roller 212 through the oil spray pipe 209 and the one-way valve in the through hole 206 to lubricate the roller 212, prevent excessive wear of the roller 212, and extend the service life of the roller 212. When the roller 212 rotates together with the kiln body, the scraper 211 can scrape off the dust adhering to the roller 212 to prevent the dust from sticking to the roller 212 and causing inaccurate measurement results. The scraped dust can be washed away by the oil sprayed onto the roller 212 to prevent dust accumulation from reducing the dust removal effect.
