Description

Technical Field

[0001] This invention relates to the field of coal washing and processing, specifically to an intelligent conveying device for coal slime blending. Background Technology

[0002] Coal washing and processing is a core link in the clean and efficient utilization of coal industrial chain. Through a series of processes such as sorting, desliming, and dewatering, impurities such as gangue, ash, and sulfur in raw coal can be removed, and products of different particle sizes and qualities such as clean coal, middlings, and coal slime can be separated. This is a necessary process to improve coal utilization efficiency and reduce coal combustion pollutant emissions. Coal slime, as a fine-particle by-product generated during the washing process, has strong water retention and is difficult to dewater. It must undergo deep dewatering treatment before it can enter the subsequent blending and utilization stage. Currently, the industry generally uses ultra-high pressure filter presses for deep filtration and dewatering of coal slime. After being filtered by ultra-high pressure filter presses, the low-moisture coal slime needs to be conveyed by scraper conveyor, transferred by belt conveyor, and crushed by crusher after being unloaded. Finally, it is sent to the coal slime blending process to be mixed with the main washed coal products in proportion to form finished coal.

[0003] Traditional processes employ a manual loader-based online blending method, where the amount and rhythm of coal slime feeding rely entirely on the experience of on-site operators. Due to the subjectivity of manual operation and fluctuations in work conditions, this method cannot achieve continuous, uniform, and quantitative coal slime feeding. The instantaneous feeding volume fluctuates greatly, and the problem of uneven feeding is very prominent. Therefore, this invention provides an intelligent conveying device for coal slime blending to solve the above-mentioned problems. Summary of the Invention

An adjustment groove is provided on the side wall of the rotating shaft corresponding to the position of the shaft plate.

[0012] As a further embodiment of the present invention, a fixing frame is installed on the inner side of the shaft plate. The fixing frame is a U-shaped plate. A connecting plate is fixedly installed on the end of the fixing frame near the inner cylinder. The end of the connecting plate away from the fixing frame is fixedly connected to the outer wall of the inner cylinder. A plurality of vibrating elements are arranged at intervals on the inner side of the fixing frame. Each vibrating element includes two base plates. The two base plates are arranged perpendicularly and mirror-imagely. Both ends of the base plates extend out of the fixing frame.

[0013] As a further embodiment of the present invention, a through groove is provided on the side wall of the fixed frame corresponding to the position of the contact block.

Guide rods are fixedly installed on the inner side of the shaft plate at both ends of the vibrating element. The guide rods slide through the two base plates on the vibrating element.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When using the device of the present invention, the "upper limit-empty bin" setting of two sets of rotary paddle switches is used, and the transmission channel between the buffer bin and the distributor is controlled by adjusting the limit switch. There is no need for manual observation of the material level or operation of the distributor. Only the system operation status needs to be remotely monitored in the background, which effectively eliminates the dependence on manual labor and truly achieves the effect of "automatic material stop when the bin is full and automatic material feeding when the bin is empty". This effectively improves the intelligent operation effect of the coal processing industry and effectively ensures uniform feeding during the operation.

[0015] 2. When the device of the present invention is used, the material level of the buffer bin is precisely controlled by the "upper limit-empty bin" rotary switch to ensure that the material level is dynamically balanced in the range from empty bin to full bin, providing a continuous and uniform feed source for the adjustable frequency coal feeder. With the frequency adjustment function of the feeder, the coal slime blending ratio is accurately controllable, the consistency of finished coal quality is significantly improved, and the quality disputes caused by uneven blending are effectively reduced.

[0016] 3. When the device of the present invention is used, the alternating triggering of two sets of rotary switches and the automated action of the distributor effectively avoid the problems of material interruption and overflow, significantly increasing the effective operating time of the equipment, and ensuring that the coal slime blending process is continuous and uninterrupted, thereby greatly improving the overall production efficiency of the washing and beneficiation system.

[0017] 4. When the device of the present invention is used, it effectively eliminates the manual on-site duty and operation links, greatly reduces manpower input, lowers labor costs, avoids the risk of misoperation caused by human fatigue operation, and avoids safety hazards such as collisions and dust that may be faced in on-site operations, effectively improving the inherent safety level of the coal slime blending process.

[0018] 5. When the device of the present invention is used, the anti-blocking component can reciprocate to drive the insert rod to scrape and puncture at the bottom of the buffer chamber during operation, so that the coal slurry accumulated at the outlet is loosened under the scraping and puncturing, effectively reducing the occurrence of coal slurry blockage at the outlet and effectively ensuring the transmission efficiency of coal slurry.

[0019] 6. When the device of the present invention is used, when the rotating shaft drives the shaft plate to rotate, one of the shaft plates contacts the push block and adjusts, which will drive the other shaft plates to adjust through the inner shaft rod. After the shaft plate separates from the push block, it will be reset by the reset spring and vibrate, thereby driving several shaft plates to vibrate during operation. It can effectively break up the agglomerated coal slime through the rotation and vibration of the shaft plate, reduce the occurrence of coal slime agglomeration and transmission, and facilitate subsequent coal slime blending and processing.

[0020] 7. When the device of the present invention is in use, when the shaft plate moves, the shaft plate will drive the vibrating element to move synchronously. The main pressure block on the vibrating element will contact the auxiliary pressure block on the base plate. The auxiliary pressure block and the main pressure block are transmitted by the pressure of the inclined surface, so that the base plate is pressed and moves away from the shaft plate. When the main pressure block passes the auxiliary pressure block, the base plate is reset by the elastic force of the auxiliary spring, so that the contact block impacts the inner wall of the shaft plate with elastic force, thereby causing the inner wall of the shaft plate to vibrate. When the inner wall of the shaft plate vibrates, it can not only help to break up the coal slime lumps, but also prevent the coal slime from sticking to the shaft plate. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10 In this embodiment of the invention, an intelligent conveying device for coal slime blending includes a buffer bin 1 and a distributor 2. The bottom of the buffer bin 1 is connected to an adjustable frequency coal feeder. The distributor 2 is a Y-shaped transmission box, with one bottom end connected to the top of the buffer bin 1 and the top of the distributor 2 connected to a coal slime transfer belt conveyor. Rotary paddle switches 3 are installed on the top and bottom of the side walls of the buffer bin 1. The rotary paddle switches 3 are publicly available technology and will not be described in detail here. Limit switches are installed inside the distributor 2, and the limit switches are electrically connected to the two rotary paddle switches 3. The top rotary paddle switch 3 is a full-bin trigger switch, and the bottom rotary paddle switch 3 is an empty-bin trigger switch. Initial state... In the current state, the bottom rotary switch 3 is in the triggered state. The transmission channel on the distributor 2 is connected to the buffer bin 1 through the limit switch. Coal slurry can enter the buffer bin 1 normally. As the coal slurry continues to enter the buffer bin 1 and accumulates, when the coal slurry accumulates to the position of the top rotary switch 3, the rotary switch 3 is triggered and controls the limit switch to adjust, so that the transmission channel from the distributor 2 to the buffer bin 1 is closed to prevent coal slurry from overflowing. As the coal slurry continues to be discharged, when the coal slurry level reaches the bottom rotary switch 3, the rotary switch 3 is triggered again and controls the limit switch to adjust, so that the transmission channel from the distributor 2 to the buffer bin 1 is opened, and the coal slurry continues to enter the buffer bin 1 for replenishment transmission. An anti-blocking component is installed at the bottom inner side of the buffer chamber 1 corresponding to the discharge port. A dispersing component is installed at the bottom of the buffer chamber 1 corresponding to the discharge port. A drive motor 8 is installed on one side of the dispersing component. The output shaft of the drive motor 8 is fixedly connected to the dispersing component. A transmission component is installed between the dispersing component and the anti-blocking component. Through the transmission component, the anti-blocking component can be adjusted up and down inside the buffer chamber 1 while the drive motor 8 drives the dispersing component to rotate. The anti-blocking component includes an inner box 12, which is fixedly installed inside the buffer chamber 1. The inner box 12 is hollow. A lifting plate 14 is provided on the inner side of the inner box 12. The lifting plate 14 can be adjusted up and down within the inner box 12. Slide grooves 13 are provided on both sides of the inner box 12 corresponding to the side walls of the buffer chamber 1. The slide grooves 13 penetrate the side walls of the buffer chamber 1. Lifting plates 11 are provided at both ends of the lifting plate 14. The lifting plates 11 are located outside the buffer chamber 1. The end of the lifting plate 14 near the lifting plate 11 passes through the slide groove 13 and is fixedly connected to the lifting plate 11. The end of the lifting plate 11 away from the lifting plate 14 is fixedly connected to the transmission component. The bottom of the inner box 12 is provided with movable holes 23 at intervals. The movable holes 23 penetrate the bottom wall of the inner box 12 and are interconnected with the inside of the inner box 12. An auxiliary rubber plate 24 is installed on the inner side of the movable holes 23. The auxiliary rubber plate 24 is a rubber plate that can be deformed under pressure. A scraper sleeve 25 is fixedly installed on the bottom of the auxiliary rubber plate 24. The scraper sleeve 25 gradually narrows from top to bottom. The inside of the scraper sleeve 25 is hollow. An insert rod 17 is installed on the inner side of the inner box 12 corresponding to the position of the movable holes 23. The bottom of the insert rod 17 slides through the movable holes 23 and passes through the scraper sleeve 25 to move to the bottom of the inner box 12. The bottom of the insert rod 17 is conical. A top block 16 is fixedly installed on the top of the insert rod 17. A side rod 15 is fixedly installed on the bottom of the lifting plate 14 corresponding to one side of the top block 16. A movable rod 27 is installed on the bottom side wall of the side rod 15 near the top block 16. The top block 16 is installed on the movable rod 27. The transmission component can drive the lifting plate 11 to lift and adjust, which in turn drives the lifting plate 14 to lift and adjust within the inner box 12. This causes the bottom of the insertion rod 17 to lift and press at the corresponding discharge port position inside the buffer chamber 1, loosening the coal sludge accumulated at the discharge port, facilitating the external discharge and reducing the occurrence of coal sludge clogging the discharge port. The top block 16 is rotatably mounted on the movable rod 27. A torsion spring 28 is installed on the outer wall of the movable rod 27. One end of the torsion spring 28 is fixedly mounted on the outer wall of the movable rod 27, and the other end of the torsion spring 28 is fixedly connected to the inner wall of the top block 16. The top block 16 can rotate on the movable rod 27. The top of the top block 16 is arc-shaped. A pressure guide block 22 is installed on the top of the top block 16. The pressure guide block 22 is triangular. The end of the pressure guide block 22 near the top block 16 is arc-shaped. The bottom arc end of the pressure guide block 22 is offset from the top arc end of the top block 16. The top arc end of the top block 16 corresponds to the inclined surface of the pressure guide block 22. One side of the pressure guide block 22 is fixedly connected to the inner wall of the inner box 12. When the lifting plate 14 drives the side rod 15 to rise, the movable rod 27 on the side rod 15 will drive the top block 16 to rise synchronously. When the top of the top block 16 contacts the inclined surface of the pressure guide block 22, it is squeezed by the inclined surface, causing the top block 16 to rotate on the movable rod 27. The bottom of the corresponding insertion rod 17 will deflect synchronously. When the lifting plate 14 descends, the top block 16 will rotate and reset through the torsion spring 28, so that the bottom of the insertion rod 17 can rise and fall and scrape at the corresponding discharge port position in the buffer chamber 1. This can effectively scrape and press the coal sludge accumulated at the discharge port, making it easier for the coal sludge to loosen and reducing the occurrence of blockage at the discharge port position of the buffer chamber 1.

[0034] Side scrapers 26 are fixedly installed on the bottom side wall of the insertion rod 17. The side scrapers 26 can assist the insertion rod 17 in scraping operations, improve the scraping effect of the insertion rod 17, and improve the loosening effect of coal slime. The dispersing component includes a discharge frame 9, which is fixedly installed at the bottom of the buffer chamber 1 at the corresponding discharge port position. The discharge frame 9 is a U-shaped plate, and drive disks 10 are movably installed on both sides of the discharge frame 9. One end of the transmission component is fixedly connected to the lifting disk 11, and the other end of the transmission component is movably installed on the drive disk 10. The drive motor 8 is fixedly installed on the side wall of the discharge frame 9, and the output end of the drive motor 8 is fixedly connected to one of the drive disks 10. A rotating shaft 18 is fixedly installed between the two drive disks 10. The two ends of the rotating shaft 18 slide through the side wall of the discharge frame 9, and shaft plates 19 are installed around the outer wall of the rotating shaft 18 at intervals. The drive motor 8 starts and drives the drive disk 10 to rotate, which in turn drives the rotating shaft 18 to rotate inside the discharge frame 9. Through the several shaft plates 19 set on the side wall of the rotating shaft 18, the coal slurry transmitted from the discharge port of the buffer bin 1 can be broken up under the rotation of the rotating shaft 18, so as to avoid it from being transported in clumps and affecting the coal slurry proportioning operation. The interior of the rotating shaft 18 is hollow, and an inner cylinder 32 is fixedly installed inside the rotating shaft 18. Both ends of the inner cylinder 32 are fixedly installed on the inner side of the rotating shaft 18. An adjustment groove 31 is provided on the side wall of the rotating shaft 18 corresponding to the position of the shaft plate 19. The adjustment groove 31 penetrates the side wall of the rotating shaft 18 and communicates with the interior of the rotating shaft 18. The end of the shaft plate 19 closest to the interior of the rotating shaft 18 extends into the rotating shaft 18 through the adjustment groove 31. Both ends of the shaft plate 19 closest to the interior of the rotating shaft 18 are fixedly installed with pressing rods 34, and the end of the pressing rods 34 away from the shaft plate 19 slides. A return spring 35 is fixedly installed on the side wall of the shaft plate 19 corresponding to the position of the extrusion rod 34, and the extrusion rod 34 is located inside the return spring 35. The end of the extrusion rod 34 away from the shaft plate 19 is fixedly installed on the outer wall of the inner cylinder 32. An inner shaft rod 33 is movably installed on the inner side of the inner cylinder 32. The inner shaft rod 33 is located between the ends of several extrusion rods 34 away from the shaft plate 19. A push block 45 is fixedly installed on the inner wall of the discharge frame 9 near the rotating shaft 18. The push block 45 is a triangular plate, and the inclined surface of the push block 45 corresponds to the rotation direction of the rotating shaft 18. When the rotating shaft 18 drives the shaft plate 19 to rotate, the end of the shaft plate 19 away from the rotating shaft 18 will contact the inclined surface of the push block 45 and be squeezed by the inclined surface, causing the shaft plate 19 at the corresponding position to move into the rotating shaft 18, and drive the extrusion rod 34 to squeeze the inner shaft rod 33. When the inner shaft rod 33 is squeezed by pressure on one side, the inner shaft rod 33 will move in the inner cylinder 32 and squeeze several other extrusion rods 34, which will in turn drive the other shaft plates 19 to adjust. When the shaft plate 19 and the push block 45 are separated, the shaft plate 19 will be elastically reset by the return spring 35, generating vibration, so that several shaft plates 19 will vibrate synchronously, and the vibration generated by the shaft plate 19 can be used to vibrate the coal slime, making it easier to break up the coal slime into clumps. The shaft plate 19 is hollow inside. A fixing frame 36, which is a U-shaped plate, is installed on the inner side of the shaft plate 19. A connecting plate 37 is fixedly installed on the end of the fixing frame 36 near the inner cylinder 32. The end of the connecting plate 37 away from the fixing frame 36 is fixedly connected to the outer wall of the inner cylinder 32. Several vibrating elements are arranged at intervals on the inner side of the fixing frame 36. Each vibrating element includes two base plates 38, which are arranged perpendicularly and mirror-imagely. Both ends of the base plates 38 extend out of the fixing frame 36. Auxiliary springs 39 are fixedly installed on both ends of the base plates 38 near the shaft plate 19. The ends of the auxiliary springs 39 away from the base plates 38 are fixedly connected to the inner wall of the shaft plate 19. There is a gap between the two base plates 38. Contact blocks are fixedly installed at intervals on the side of the base plates 38 near the shaft plate 19. The contact block 41 and the auxiliary pressure block 42 are arranged in an alternating manner. A through groove 43 is provided on the side wall of the fixed frame 36 corresponding to the position of the contact block 41. The contact block 41 can move in the through groove 43. A main pressure block 44 is fixedly installed between two adjacent through grooves 43 on the inner side of the fixed frame 36. The main pressure block 44 is a triangular block. The position of the main pressure block 44 corresponds to the position of the auxiliary pressure block 42. The conical end of the main pressure block 44 corresponds to the conical end of the auxiliary pressure block 42. A guide rod 40 is fixedly installed on the inner side of the shaft plate 19 corresponding to both ends of the vibrating element. The guide rod 40 slides through the two base plates 38 on the vibrating element and vertically limits the base plates 38 through the guide rod 40. When the shaft plate 19 moves, it drives the vibrating element to move synchronously. At this time, the inner cylinder 32 is fixedly connected to the rotating shaft 18, which makes the fixed frame 36 and the connecting plate 37 fixed. Therefore, when the vibrating element moves, the main pressure block 44 on the vibrating element will contact the auxiliary pressure block 42 on the base plate 38. The auxiliary pressure block 42 and the main pressure block 44 are transmitted through the inclined surface, which makes the base plate 38 move away from the shaft plate 19 under pressure. When the main pressure block 44 passes the auxiliary pressure block 42, the base plate 38 is reset by the elastic force of the auxiliary spring 39, which makes the contact block 41 impact the inner wall of the shaft plate 19 with elastic force, thereby causing the inner wall of the shaft plate 19 to vibrate. When the inner wall of the shaft plate 19 vibrates, it can not only help to break up the coal slime lumps, but also prevent the coal slime from sticking to the shaft plate 19.

[0035] The transmission assembly includes a limiting rod 20, which is fixedly installed on the lifting plate 11 on the side away from the lifting plate 14. An annular transmission groove is formed on the side wall of the drive plate 10. Guide grooves 29 are formed on both sides of the inner wall of the transmission groove on the drive plate 10. The guide grooves 29 are elliptical grooves. The end of the limiting rod 20 away from the lifting plate 11 extends into the transmission groove on the drive plate 10. Rollers 30 are movably installed on both sides of the bottom of the limiting rod 20. The end of the rollers 30 away from the limiting rod 20 extends into the guide groove 29. A limiting sleeve 21 is fixedly installed on the side wall of the buffer chamber 1. The position of the limiting sleeve 21 corresponds to the position of the limiting rod 20. The end of the limiting rod 20 away from the lifting plate 11 slides through the limiting sleeve 21 and extends into the transmission groove on the drive plate 10.

[0036] When the drive disc 10 rotates, the rollers 30 on both sides of the bottom of the limit rod 20 will move in the guide groove 29 as the drive disc 10 rotates, so that the rollers 30 will move from the narrow end to the wide end of the guide groove 29, so that the limit rod 20 can be adjusted in the transmission groove on the drive disc 10, thereby driving the lifting disc 11 to be adjusted in the height.

[0037] The limit switch includes a limit plate 46, which is inclinedly installed on the inner side of the distributor 2 corresponding to the corner position of the Y-shaped channel. A rotating plate 7 is installed on the outer wall of the distributor 2. The bottom of the rotating plate 7 slides through the side wall of the distributor 2 and is fixedly connected to the limit plate 46. A mounting bracket 4 is fixedly installed on the top of the side wall of the distributor 2. A telescopic cylinder 5 is movably installed on the inner side of the mounting bracket 4. A push rod 6 is fixedly installed on the output end of the telescopic cylinder 5. The bottom of the push rod 6 and the top of the rotating plate 7 are movably connected to each other. The telescopic cylinder 5 is used for telescopic adjustment, which in turn drives the push rod 6 to move closer to or further away from the telescopic cylinder 5. This causes the rotating plate 7 to rotate on the distributor 2, so that the limit plate 46 blocks and adjusts the transmission channel under the rotation of the rotating plate 7. The telescopic cylinder 5 can rotate on the mounting frame 4. When the rotating plate 7 rotates, the distance between the top of the rotating plate 7 and the telescopic cylinder 5 will change. At this time, the telescopic cylinder 5 can adjust the distance by rotating on the mounting frame 4, so as to effectively control the rotation adjustment of the rotating plate 7.

[0038] The working principle of this invention is: When the device of the present invention is used, the low-moisture coal slime output by the ultra-high pressure filter press is conveyed by a scraper conveyor and transferred by a belt conveyor, and then enters the crusher to be crushed to the particle size that meets the blending requirements. Subsequently, it is conveyed to the distributor 2 by the coal slime transfer belt conveyor. In the initial state, if the buffer bin 1 is empty, the bottom rotary switch 3 is triggered, and the connecting channel between the distributor 2 and the buffer bin 1 is opened under the adjustment of the limit switch. The coal slurry can enter the buffer bin 1 normally, and the adjustable frequency coal feeder will evenly transport the coal slurry to another set of coal slurry transfer belt conveyors according to the preset blending frequency. Coal slime continuously enters and accumulates in buffer silo 1. When the material level rises to the installation position of the top rotary switch 3, the top rotary switch 3 is triggered, and the communication channel between the distributor 2 and the buffer silo 1 is closed under the adjustment of the limit switch, cutting off the feeding channel to the buffer silo 1 and preventing coal slime from overflowing. After the coal slurry in the buffer bin 1 is continuously conveyed by the adjustable frequency coal feeder, the material level gradually decreases. When the material level drops to the installation position of the bottom rotary switch 3, the bottom rotary switch 3 is immediately triggered. The communication channel between the distributor 2 and the buffer bin 1 is opened under the adjustment of the limit switch, and the coal slurry continues to enter the buffer bin 1 to complete the feeding. By repeatedly triggering two rotary switches 3, the connecting channel between the distributor 2 and the buffer bin 1 is repeatedly adjusted under the regulation of the limit switch, forming a complete automated cycle of "empty bin feeding - coal slime accumulation - full bin stopping - coal slime consumption - empty bin feeding". The coal slime level in buffer bin 1 is always dynamically balanced within the range of empty to full bin, and the adjustable frequency coal feeder continuously obtains a uniform and stable feed source, realizing fully automated blending of coal slime. When the coal slurry is transported to the discharge port of the buffer bin 1, the drive motor 8 starts and drives the drive disc 10 to rotate. Under the adjustment of the transmission component, the lifting disc 11 drives the lifting plate 14 to adjust the height within the inner box 12. When the insert rod 17 rises, the top block 16 contacts the pressure guide block 22. Under the inclined guide of the inclined surface, the top block 16 rotates on the movable rod 27, causing the bottom of the insert rod 17 to shift. When the insert rod 17 falls, the top block 16 is reset and rotated by the torsion spring 28, so that the insert rod 17 can perform lifting and scraping operations on the discharge port of the buffer bin 1, avoiding the coal slurry from clogging the discharge port of the buffer bin 1. When the coal slurry is discharged from the outlet of the buffer bin 1, the rotating shaft 18 rotates under the drive of the drive disc 10, causing the shaft plate 19 and the push block 45 arranged around the side wall of the rotating shaft 18 to come into contact. This causes the shaft plate 19 to move and adjust inward into the rotating shaft 18. Under the push of the extrusion rod 34, the inner shaft rod 33 drives several other extrusion rods 34 to adjust, thereby adjusting several shaft plates 19. When the shaft plate 19 and the push block 45 are separated, the shaft plate 19 is elastically reset by the return spring 35, and the shaft plate 19 vibrates. Simultaneously, several shaft plates 19 vibrate under the reset adjustment of the return spring 35, which can effectively vibrate and beat the coal slurry, making it easier to disperse the coal slurry and reduce the coal slurry agglomeration and transmission.
