Description

Technical Field

[0001] This utility model relates to the technical field of rare earth chloride extraction, and in particular to a sodium phosphate dehydration centrifuge. Background Technology

[0002] In the extraction process of rare earth chloride, the alkaline fusion method is generally used to extract it from monazite. The alkaline fusion extraction process generates a large amount of waste, the main component of which is sodium phosphate. In order to reduce production costs, sodium phosphate is often reused. When reusing sodium phosphate, centrifuges are often used to remove moisture from the sodium phosphate. However, because the size of sodium phosphate particles varies, sodium phosphate particles often clog the drain hole of the centrifuge drum, affecting the working efficiency of the centrifuge. Utility Model Content

[0003] In order to reduce the probability of sodium phosphate particles clogging the drain hole of the drum and thus affecting the dehydration efficiency of the centrifuge, this application provides a sodium phosphate dehydration centrifuge.

[0004] This application provides a sodium phosphate dehydration centrifuge, which adopts the following technical solution:

[0005] A sodium phosphate dehydration centrifuge includes a support frame, a housing fixedly connected to the support frame, a rotating drum rotatably connected inside the housing via a drive mechanism, several drainage holes on the side wall of the rotating drum, an end cap mounted on the top of the housing via a first fixing bolt, a drain pipe fixedly connected to the bottom of the housing, a lifting mechanism for driving the rotating drum upward and a rinsing mechanism for rinsing the drainage holes, and the rotating drum and the drive mechanism connected via a connecting mechanism.

[0006] By adopting the above technical solution, when cleaning the drum, the end cover is first manually removed from the outer shell, and then the drive mechanism is separated from the drum through the connecting mechanism. Then the lifting mechanism is activated to move the drum out of the outer shell, and then the rinsing mechanism rinses the drain hole on the drum, thereby reducing the probability of sodium phosphate particles clogging the drain hole of the drum and causing a decrease in centrifuge dehydration efficiency.

[0007] Optionally, the lifting mechanism includes a mounting frame, which is fixedly connected to the support frame. Two lifting rods are slidably connected to the mounting frame via a power assembly. Each of the two lifting rods has a through groove at one end that is far from each other. A limit rod is inserted into the groove. Two fixing blocks are fixedly connected to the side wall of the drum, and each of the two fixing blocks has a connecting groove.

[0008] By adopting the above technical solution, when the drum is lifted, the power assembly drives two lifting rods to be inserted into two connecting slots. Then, the two limiting rods are manually inserted into the two grooves respectively. Then, the power assembly drives the lifting rods to rise. The lifting rods drive the drum to rise through the limiting rods and the fixing block, so that the drum moves out of the outer shell.

[0009] Optionally, the mounting bracket has a sliding groove on the side wall near the lifting rod. The power assembly includes a second motor, which is fixedly connected to the mounting bracket. A lead screw is fixedly connected to the output shaft of the second motor. A slider is slidably connected in the sliding groove. A lead screw nut is installed in the slider and cooperates with the lead screw. An installation rod is fixedly connected to the slider and is fixedly connected to the lifting rod.

[0010] By adopting the above technical solution, when the lifting rod moves, the second motor starts, the second motor drives the lead screw to rotate, the lead screw drives the slider to slide through the lead screw nut, and the slider drives the lifting rod to move through the mounting rod.

[0011] Optionally, the flushing mechanism includes a water storage tank installed on the ground. A pressure pump is installed on the water storage tank, and an inlet pipe connected to the water storage tank is installed on the pressure pump. An outlet pipe is fixedly connected to the outlet end of the pressure pump. A water storage ring is slidably connected to the mounting frame via a lifting assembly. Multiple nozzles are installed on the inner wall of the water storage ring. The end of the outlet pipe away from the pressure pump is connected to the water storage ring.

[0012] By adopting the above technical solution, when cleaning the drain holes on the drum, the pressure pump starts, which transports water from the water tank to the water storage ring and sprays it out through the nozzle. The sprayed water cleans the drain holes, thus achieving the cleaning of the drain holes. Sodium phosphate particles block the drum from the inside to the outside, so cleaning from the outside to the inside of the drum will be more effective. Therefore, by setting nozzles on the outside of the drum, the cleaning effect is better.

[0013] Optionally, the lifting assembly includes a cylinder, which is fixedly connected to the mounting rod. A first connecting rod is fixedly connected to the piston shaft of the cylinder. A second connecting rod is fixedly connected to the end of the first connecting rod away from the cylinder. The end of the second connecting rod away from the first connecting rod is fixedly connected to the water storage ring.

[0014] By adopting the above technical solution, when cleaning the drain holes of the drum, the cylinder is started, the cylinder drives the first connecting rod to move, the first connecting rod drives the second connecting rod to move, the second connecting rod drives the water storage ring to move, and the water storage ring drives the nozzle to move, thereby cleaning the entire drum and realizing the cleaning of the drain holes on the entire drum.

[0015] Optionally, the drive mechanism includes a first motor, which is fixedly connected to the support frame. A first pulley is fixedly connected to the output shaft of the first motor. A rotating shaft is also rotatably connected to the support frame. A second pulley is fixedly connected to the rotating shaft. A belt is rotatably connected to both the first pulley and the second pulley. The rotating shaft is connected to the connecting mechanism.

[0016] By adopting the above technical solution, when the drum rotates, the first motor starts, the first motor drives the first pulley to rotate, the first pulley drives the second pulley to rotate via a belt, the second pulley drives the rotating shaft to rotate, and the rotating shaft drives the drum to rotate via a connecting mechanism.

[0017] Optionally, the connecting mechanism includes a connecting block, which is fixedly connected to the bottom wall of the drum. A slot is formed on the end face of the connecting block away from the drum. A first limiting groove is formed on the side wall of the slot. A first limiting block is fixedly connected to the side wall of the rotating shaft. One end of the rotating shaft near the drum is inserted into the slot. The first limiting block is inserted into the first limiting groove. A fixing ring is also fixedly connected to the rotating shaft. The connecting mechanism also includes a plurality of second fixing bolts, which are threaded through the fixing ring and connected to the connecting block.

[0018] By adopting the above technical solution, the connection block and the first limiting block enable the detachable connection between the rotating shaft and the drum, enabling the drum to rotate. Furthermore, the setting of the fixing ring and the second fixing bolt reduces the probability of the first limiting block sliding out of the first limiting groove, and also enables the drum to separate from the rotating shaft when it is lifted.

[0019] Optionally, a cleaning mechanism is also installed inside the housing. The cleaning mechanism includes a scraper and a transmission assembly. The scraper is rotatably connected inside the housing via the transmission assembly. The transmission assembly includes a connecting ring, which is rotatably connected to the bottom wall inside the housing. A second limiting groove is provided on the inner side wall of the connecting ring. A second limiting block is fixedly connected to the side wall of the connecting block and is inserted into the second limiting groove. A third connecting rod is fixedly connected to the outer side wall of the connecting ring, and the end of the third connecting rod away from the connecting ring is fixedly connected to the scraper.

[0020] By adopting the above technical solution, a small amount of sodium phosphate will be discharged from the drain hole during the centrifugal dehydration process and adhere to the inner wall of the outer shell. Over time, as more and more sodium phosphate adheres to the inner wall of the outer shell, it will collide with the drum, thus affecting the service life of the drum. When the drum rotates, the drum drives the connecting ring to rotate through the connecting block and the second limiting block. The connecting ring drives the scraper to rotate through the third connecting rod. The scraper scrapes off the sodium phosphate adhering to the inner wall of the outer shell, thereby reducing the probability that the sodium phosphate adhering to the inner wall of the outer shell will collide with the drum and affect the service life of the drum.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. When cleaning the drum, first manually remove the end cover from the outer shell, then separate the drive mechanism from the drum through the connecting mechanism, then start the lifting mechanism to move the drum out of the outer shell, and then the flushing mechanism flushes the drain hole on the drum, thereby reducing the probability of sodium phosphate particles clogging the drain hole of the drum and causing the centrifuge dehydration efficiency to decrease.

[0023] 2. When cleaning the drain holes on the drum, the pressure pump starts, which transports water from the storage tank to the storage ring and sprays it out through the nozzles. The sprayed water cleans the drain holes, thus achieving the cleaning effect. Sodium phosphate particles block the drum from the inside to the outside, so cleaning from the outside to the inside of the drum is more effective. Therefore, by setting nozzles on the outside of the drum, the cleaning effect is better.

[0024] 3. When cleaning the drain holes of the drum, the cylinder is started, the cylinder drives the first connecting rod to move, the first connecting rod drives the second connecting rod to move, the second connecting rod drives the water storage ring to move, and the water storage ring drives the nozzle to move, thereby cleaning the entire drum and realizing the cleaning of the drain holes on the entire drum;

[0025] 4. During centrifugal dehydration, a small amount of sodium phosphate will be discharged from the drain hole and adhere to the inner wall of the outer shell. Over time, as more and more sodium phosphate adheres to the inner wall of the outer shell, it will collide with the drum, thus affecting the service life of the drum. When the drum rotates, the drum drives the connecting ring to rotate through the connecting block and the second limiting block. The connecting ring drives the scraper to rotate through the third connecting rod. The scraper scrapes off the sodium phosphate adhering to the inner wall of the outer shell, thereby reducing the probability of the sodium phosphate adhering to the inner wall of the outer shell colliding with the drum and affecting the service life of the drum.

[0038] When cleaning the clogged drain hole 121 on the drum 12, first manually remove the end cover 13 from the outer casing 11, then separate the drive mechanism 2 from the drum 12 via the connecting mechanism 3. Next, the lifting mechanism 4 is activated to move the drum 12 out of the outer casing 11. Then, the flushing mechanism 5 flushes the drain hole 121 on the drum 12, thereby reducing the probability of sodium phosphate particles clogging the drain hole 121 and causing a decrease in centrifuge dehydration efficiency.

[0039] refer to Figure 2 The drive mechanism 2 includes a first motor 21, which is fixedly connected to the end face of the support frame 1 near the end cover 13. A first pulley 22 is fixedly connected to the output shaft of the first motor 21. A rotating shaft 23 is also rotatably connected to the end face of the support frame 1 near the end cover 13. The rotating shaft 23 is connected to the connecting mechanism 3. A second pulley 24 is fixedly connected to the rotating shaft 23. A belt 25 is rotatably connected to both the first pulley 22 and the second pulley 24.

[0040] When the drum 12 rotates, the first motor 21 starts, and the first motor 21 drives the first pulley 22 to rotate. The first pulley 22 drives the second pulley 24 to rotate through the belt 25. The second pulley 24 drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the drum 12 to rotate through the connecting mechanism 3.

[0041] refer to Figure 3The connecting mechanism 3 includes a connecting block 31, which is fixedly connected to the end face of the drum 12 away from the end cover 13. A slot 311 is provided on the end face of the connecting block 31 away from the drum 12. A first limiting groove 312 is provided on the side wall of the slot 311. A first limiting block 32 is fixedly connected to the peripheral side wall of the rotating shaft 23. One end of the rotating shaft 23 away from the support frame 1 is inserted into the slot 311.

[0042] The connection block 31 and the first limiting block 32 enable the detachable connection between the rotating shaft 23 and the drum 12, enabling the drum 12 to rotate. The fixing ring 33 and the second fixing bolt 34 reduce the probability of the first limiting block 32 sliding out of the first limiting groove 312, and also enable the drum 12 to separate from the rotating shaft 23 when it is lifted.

[0043] refer to Figure 4 and Figure 5 The lifting mechanism 4 includes a mounting frame 42, which is fixedly connected to the end face of the support frame 1 near the end cover 13. Two lifting rods 41 are slidably connected to the mounting frame 42 via a power assembly 45. A sliding groove 421 is provided on the inner side wall of the mounting frame 42. The power assembly 45 includes a second motor 452, which is fixedly connected to the end face of the mounting frame 42 away from the support frame 1. A lead screw 453 is fixedly connected to the output shaft of the second motor 452. A slider 45 is slidably connected in each of the two sliding grooves 421. 4. A lead screw nut is installed in the slider 454 near the second motor 452. The lead screw nut cooperates with the lead screw 453. The two sliders 454 are fixedly connected to the same end of the sliders 454. The two lifting rods 41 are fixedly connected to the end face of the mounting rod 451 near the support frame 1. The two lifting rods 41 are provided with through grooves at the ends of the lifting rods 41. Limit rods 44 are inserted into the grooves. Two fixing blocks 43 are fixedly connected to the side wall of the drum 12. Both fixing blocks 43 are provided with connecting grooves.

[0044] When the drum 12 is lifted, the second motor 452 starts and drives the lead screw 453 to rotate. The lead screw 453 drives the slider 454 to slide through the lead screw nut. The slider 454 drives the lifting rod 41 to move through the mounting rod 451 and insert it into the two connecting slots. Then, the two limiting rods 44 are manually inserted into the two grooves respectively. Then, the second motor 452 reverses and drives the lifting rod 41 to rise. The lifting rod 41 drives the drum 12 to rise through the limiting rod 44 and the fixing block 43, so that the drum 12 moves out of the outer shell 11.

[0045] refer to Figure 6 and Figure 7 The rinsing mechanism 5 includes a water storage tank 51, which is installed on the ground. A pressure pump 52 is installed on the end face of the water storage tank 51 away from the ground. An inlet pipe 53 connected to the water storage tank 51 is installed on the inlet end of the pressure pump 52. An outlet pipe 54 is fixedly connected to the outlet end of the pressure pump 52. A water storage ring 55 is slidably connected to the mounting bracket 42 through a lifting component 57. Multiple nozzles 56 are installed on the inner side wall of the water storage ring 55. The end of the outlet pipe 54 away from the pressure pump 52 is connected to the water storage ring 55.

[0046] When cleaning the drain hole 121 on the drum 12, the pressure pump 52 starts, which transports the water in the water storage tank 51 to the water storage ring 55 and sprays it out through the nozzle 56. The sprayed water cleans the drain hole 121, thus cleaning the drain hole 121. Sodium phosphate particles block the drum 12 from the inside to the outside, so cleaning from the outside to the inside of the drum 12 will be more effective. Therefore, by setting the nozzle 56 on the outside of the drum 12, the cleaning effect is better.

[0047] refer to Figure 7 The lifting assembly 57 includes a cylinder 571, which is fixedly connected to the end face of the mounting rod 451 away from the support frame 1. A first connecting rod 572 is fixedly connected to the piston shaft of the cylinder 571. Two second connecting rods 573 are fixedly connected to the end of the first connecting rod 572 away from the cylinder 571. The ends of the two second connecting rods 573 away from the first connecting rod 572 are fixedly connected to the water storage ring 55. When cleaning the drain hole 121 of the drum 12, the cylinder 571 is activated, which drives the first connecting rod 572 to move. The first connecting rod 572 drives the second connecting rod 573 to move. The second connecting rod 573 drives the water storage ring 55 to move. The water storage ring 55 drives the nozzle 56 to move, thereby cleaning the entire drum 12 and realizing the cleaning of the drain hole 121 on the entire drum 12.

[0048] refer to Figure 8The outer casing 11 is also equipped with a cleaning mechanism 6, which includes a scraper 61 and a transmission assembly 62. The scraper 61 is rotatably connected to the outer casing 11 through the transmission assembly 62. The transmission assembly 62 includes a connecting ring 621, which is rotatably connected to the bottom wall inside the outer casing 11. A second limiting groove 624 is provided on the inner side wall of the connecting ring 621. A second limiting block 623 is fixedly connected to the side wall of the connecting block 31. The second limiting block 623 is inserted into the second limiting groove 624. A third connecting rod 622 is fixedly connected to the outer side wall of the connecting ring 621. The end of the third connecting rod 622 away from the connecting ring 621 is fixedly connected to the scraper 61.

[0049] During centrifugal dehydration, a small amount of sodium phosphate is discharged from the drain hole 121 and adheres to the inner wall of the outer shell 11. Over time, as more and more sodium phosphate adheres to the inner wall of the outer shell 11, it will collide with the drum 12, thus affecting the service life of the drum 12. When the drum 12 rotates, the drum 12 drives the connecting ring 621 to rotate through the connecting block 31 and the second limiting block 623. The connecting ring 621 drives the scraper 61 to rotate through the third connecting rod 622. The scraper 61 scrapes off the sodium phosphate adhering to the inner wall of the outer shell 11, thereby reducing the probability that the sodium phosphate adhering to the inner wall of the outer shell 11 will collide with the drum 12 and affect the service life of the drum 12.

[0050] The implementation principle of a sodium phosphate dehydration centrifuge according to an embodiment of this application is as follows: When cleaning the drum 12, first manually remove the end cover 13 from the outer shell 11, and then manually remove the fixing ring 33 from the connecting block 31; then the second motor 452 is started, and the second motor 452 drives the lead screw 453 to rotate. The lead screw 453 drives the slider 454 to slide through the lead screw nut. The slider 454 drives the lifting rod 41 to move through the mounting rod 451 and insert it into the two communicating slots. Then, manually insert the two limiting rods 44 into the two grooves respectively. Then, the second motor 452 reverses to drive the lifting rod 41. The lifting rod 41 rises, driving the drum 12 upward through the limiting rod 44 and the fixing block 43, causing the drum 12 to move out of the outer shell 11; then the pressure pump 52 starts, transporting the water in the water tank 51 to the water storage ring 55, and spraying it out through the nozzle 56. The sprayed water cleans the drain hole 121. At the same time, the cylinder 571 starts, driving the first connecting rod 572 to move, the first connecting rod 572 to move the second connecting rod 573 to move, the second connecting rod 573 to move the water storage ring 55, and the water storage ring 55 to move the nozzle 56, thereby cleaning the entire drum 12.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
