Description

Technical Field

[0001] This invention relates to the field of chemical production, specifically to a device for lightly rolling tantalum hydroxide and niobium hydroxide into powder after drying. Background Technology

[0002] In the production of tantalum hydroxide and niobium hydroxide, tantalum liquid is fed into a neutralization tank. Liquid ammonia is vaporized by a vaporizer and then transported to a silver liquid neutralization tank. Ammonia gas is then used to neutralize the ammonia to generate silver hydroxide slurry. The slurry is pumped into a filter press, where it is blown and water-pressed. The residue is discharged into a washing and adjusting tank for stirring, and then pumped back into the filter press for further filtration. The filtered silver hydroxide is then shoveled into a clean stainless steel tray and loaded from top to bottom into a box-type drying oven. The drying temperature is controlled at 100-120℃ for 20-60 minutes, until it can be easily crushed into powder by hand.

[0003] In particular, the process of lightly rolling the powder into powder is not efficient for industrial production. Currently, the relevant equipment has a rolling and pressing device. The powder after rolling and pressing often sticks tightly to the material tray, which causes some powder to adhere to the tray. Therefore, after lightly rolling, simply tilting the tray is obviously not enough to remove all the powder. At this point, manual intervention may be required, which is time-consuming and affects production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a device for lightly rolling tantalum hydroxide and niobium hydroxide into powder after drying, so as to solve the problems mentioned in the background art.

The shaft is connected to the output shaft of the drive motor and the rotation shaft of the rolling roller respectively by a first transmission belt and a second transmission belt.

[0013] As a further embodiment of the present invention: the material support plate is fixedly connected to the assembly plate, and the rolling mating mechanism includes an active structure mounted on the assembly plate and a driven structure mounted on the material support plate.

The connector is in rolling engagement with the two drive wheels, and the driven plate is provided with a sliding groove. The protrusion extends into the sliding groove and is slidably connected to the driven plate.

[0015] A transmission wheel is rotatably mounted on the rotating shaft of the connecting plate. The transmission wheel is connected to the rotating shaft of one of the driving wheels via a fourth transmission belt, and is also connected to a horizontal shaft rotatably mounted on the base via a third transmission belt. The horizontal shaft is connected to the transmission mechanism.

[0016] As a further embodiment of the present invention: the follower mechanism includes a horizontal plate slidably connected to the vertical plate and a sliding plate slidably disposed on the horizontal plate. The sliding plate is fixedly connected to the telescopic arm and is also connected to the elastic triggering mechanism.

[0020] As a further embodiment of the present invention: the limiting structure includes a limiting plate fixedly installed on the base, the limiting plate is provided with a rectangular groove and an inclined groove, the end of the telescopic rod away from the sliding plate extends into the rectangular groove and is slidably connected to the limiting plate, the column extends into the inclined groove and is slidably connected to the limiting plate, and the rectangular groove includes a first horizontal section, a first vertical section, a second horizontal section and a second vertical section connected together.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design.

[0031] 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.

[0032] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0033] Please see Figures 1-8 In this embodiment of the invention, a device for lightly rolling tantalum hydroxide and niobium hydroxide into powder after drying includes a base 1, a vertical plate 2 fixedly installed on the base 1, and a guide rail 7 fixedly installed on the base 1. It should be noted that, in actual processing, a corresponding collection trough needs to be provided at the end of the base 1 away from the vertical plate 2. The collection trough is used to collect the powder scraped off by the scraper 6. Preferably, the collection trough uses negative pressure suction to collect the powder, thereby reducing the degree of powder dispersion during the falling process.

[0034] The apparatus for lightly rolling tantalum hydroxide and niobium hydroxide into powder after drying also includes:

[0035] The connecting plate 3 is rotatably mounted on the vertical plate 2, and one end of the connecting plate 3 is fixedly connected to a material support plate 4 for placing the material to be processed;

[0036] The movable arm assembly includes a vertical arm 9 that is slidably fitted on the guide rail 7 and a telescopic arm 10 that is slidably fitted with the vertical arm 9. A rolling roller 5 is rotatably mounted on one side of the telescopic arm 10, and the rotation shaft of the rolling roller 5 is connected to a power mechanism mounted on the vertical arm 9. The power mechanism can drive the vertical arm 9 to move along the guide rail 7 and the rolling roller 5 to rotate, so that the rolling roller 5 performs a rolling action on the material in the material support plate 4.

[0037] The scraper 6 is movably mounted on the material support plate 4 and connected to a rolling engagement mechanism mounted on the material support plate 4. The rolling engagement mechanism can drive the scraper 6 to move along the length direction of the material support plate 4 so that the scraper 6 can perform a scraping action on the powder on the material support plate 4.

[0038] An elastic triggering mechanism is installed on the upright arm 9 and connected to the connecting plate 3 through a follower mechanism. The follower mechanism is also connected to the rolling engagement mechanism through a transmission mechanism. The elastic triggering mechanism is triggered at the end of the movement stroke of the rolling roller 5 to cause the follower mechanism to drive the connecting plate 3 to tilt the material support plate 4, lift the rolling roller 5, and drive the scraper 6 to perform a scraping action on the powder.

[0039] Starting from the state shown in the attached figure, the rolling roller 5 is in close contact with the inner wall of the material support plate 4, and the material support plate 4 is parallel to the base 1;

[0040] During operation, the dried material is laid flat on the support plate 4. Then, the power mechanism is activated, causing the vertical arm 9 to move along the guide rail 7 toward the vertical plate 2. At the same time, the power mechanism also drives the rolling roller 5 to rotate, so that the rolling roller 5 can roll and press the material on the support plate 4.

[0041] After the vertical arm 9 moves to the end of its stroke, the elastic trigger mechanism moves and drives the rolling roller 5 to rise through the follower mechanism. At the same time, the follower mechanism also drives the connecting plate 3 to tilt the material support plate 4 downward. In addition, the follower mechanism cooperates with the transmission mechanism, so that the transmission mechanism drives the rolling engagement mechanism to move. The rolling engagement mechanism then drives the scraper 6 to move away from the connecting plate 3 on the material support plate 4, thereby scraping off the powder on the material support plate 4.

[0042] Finally, the power mechanism changes its direction of motion, driving the vertical arm 9 to move away from the vertical plate 2 along the guide rail 7 until it is reset. Then, the elastic trigger mechanism moves again, causing all components to reset.

[0043] In summary, during operation, the rolling roller 5 moves and rotates simultaneously to achieve gentle rolling. After the gentle rolling process is completed, the elastic triggering mechanism moves, causing the rolling roller 5 to lift, the material receiving plate 4 to tilt, and the rolling drive mechanism to drive the scraper 6 to scrape off the powder. This effectively avoids the problem of incomplete collection due to powder adhesion. The mechanical cooperation between the functional components effectively improves processing efficiency and is suitable for widespread use.

[0044] It should also be noted that this device uses mechanical coordination to achieve the cooperation between various functional components. Since the residual heat of the mineral powder after drying is relatively high, if a related electronic control system is used to handle it, the high temperature and dusty environment can easily cause some electronic control and detection components to malfunction, be damaged, or produce errors, resulting in uncoordinated operation of the overall equipment.

[0045] Please refer to it again. Figure 5 The power mechanism includes a drive motor 8 mounted on the upright arm 9, a gear 11 fixedly mounted on the output shaft of the drive motor 8, and a rack plate 12 fixedly mounted on the guide rail 7 and meshing with the gear 11. The output shaft of the drive motor 8 is connected to the rotation shaft of the rolling roller 5 via a movable arm assembly. The movable arm assembly includes a first connecting arm 14 and a second connecting arm 15 rotatably connected via a shaft 13. The end of the first connecting arm 14 away from the shaft 13 is rotatably connected to the output shaft of the drive motor 8, and the end of the second connecting arm 15 away from the shaft 13 is connected to the rotation shaft of the rolling roller 5. The shaft 13 connects the output shaft of the drive motor 8 and the rotation shaft of the rolling roller 5 via a first transmission belt 16 and a second transmission belt 17, respectively.

[0046] It should be noted that since the vertical arm 9 needs to complete one round trip along the guide rail 7 during each round of processing, the drive motor 8 is a servo motor with bidirectional drive at the output end. This application does not make specific limitations on its specific model, and it can be selected according to actual needs.

[0047] When the drive motor 8 drives the gear 11 to rotate, since the gear 11 and the rack plate 12 are in a meshing state, the upright arm 9 can move along the guide rail 7. At the same time, the output shaft of the drive motor 8 drives the shaft 13 to rotate through the first transmission belt 16, and the shaft 13 drives the rolling roller 5 to rotate through the second transmission belt 17, so as to achieve the synchronization of the lateral movement and rotation of the rolling roller 5.

[0048] It should be emphasized that the gear 11 and the rolling roller 5 rotate at the same speed to ensure that there is only rolling pressure between the rolling roller 5 and the material, and no relative friction, thus preventing the powder from being pushed to one side.

[0049] The first connecting arm 14 and the second connecting arm 15 serve as a connection. When the elastic triggering mechanism moves, causing the telescopic arm 10 to slide upward in the vertical arm 9, and causing the rolling roller 5 to rise, the included angle between the first connecting arm 14 and the second connecting arm 15 increases, so as to ensure that the output shaft of the drive motor 8 and the rotation shaft of the rolling roller 5 remain connected.

[0050] Please refer to it again. Figure 6 and Figure 7 The material support plate 4 is fixedly connected to the assembly plate 34. The rolling engagement mechanism includes an active structure mounted on the assembly plate 34 and a driven structure mounted on the material support plate 4. The driven structure includes two guide rods 401 fixed to both sides of the material support plate 4, two sleeves 402 slidably sleeved on the two guide rods 401, and a driven plate 37 fixedly connected to one of the sleeves 402. The scraper 6 is fixedly installed between the two sleeves 402, and the driven plate 37 is connected to the active structure.

[0051] The active structure includes two drive wheels 35 rotatably mounted on the mounting plate 34, a connector 36 connecting the two drive wheels 35, and a protrusion 3601 provided on the connector 36. The connector 36 is in rolling engagement with the two drive wheels 35, and the driven plate 37 is provided with a sliding groove. The protrusion 3601 extends into the sliding groove and is slidably connected to the driven plate 37. A transmission wheel 33 is also rotatably mounted on the rotating shaft of the connecting plate 3. The transmission wheel 33 is connected to the rotating shaft of one of the drive wheels 35 through a fourth transmission belt 32, and is also connected to a horizontal shaft 30 rotatably mounted on the base 1 through a third transmission belt 31. The horizontal shaft 30 is connected to the transmission mechanism.

[0052] When the vertical arm 9 moves along the guide rail 7 toward the vertical plate 2 and reaches the end of its stroke, the elastic triggering mechanism moves, causing the follower mechanism to drive the connecting plate 3 to tilt the material support plate 4 downward. Correspondingly, the assembly plate 34 deflects along with the material support plate 4. During this process, the follower mechanism will cause the transmission mechanism to move, and the transmission mechanism will drive the horizontal shaft 30 to rotate. This causes the horizontal shaft 30 to drive the drive wheel 35 to rotate through the third transmission belt 31, the transmission wheel 33, and the fourth transmission belt 32. Consequently, the connecting piece 36 drives the protrusion 3601 to move, causing the protrusion 3601 to slide into contact with the driven plate 37. The driven plate 37 then drives the scraper 6 to move along the length of the material support plate 4 through the sleeve 402, scraping off the powder in the material support plate 4 and preventing the powder from sticking together.

[0053] It should be noted that the transmission of the fourth transmission belt 32 and the transmission wheel 33 is superimposed. However, since the tilt angle of the material support plate 4 is not large, and the angle that the horizontal shaft 30 needs to rotate when the scraper 6 performs the scraping action is large, the superimposed transmission amount is very small, and the amplitude of the scraper 6's action is very small. The initial position of the scraper 6 has a margin from the initial position of scraping.

[0054] Please refer to it again. Figure 1 , Figure 5 as well as Figure 6 The follower mechanism includes a horizontal plate 25 slidably connected to the vertical plate 2 and a sliding plate 24 slidably disposed on the horizontal plate 25. The sliding plate 24 is fixedly connected to the telescopic arm 10 and is also connected to the elastic triggering mechanism. A connecting rod 26 is provided between the horizontal plate 25 and the connecting plate 3. The two ends of the connecting rod 26 are respectively hinged to the connecting plate 3 and the horizontal plate 25.

[0055] When the rolling roller 5 is rolling, the telescopic arm 10 will drive the sliding plate 24 to slide along the horizontal plate 25. When the telescopic arm 10 drives the rolling roller 5 to lift, the telescopic arm 10 will drive the horizontal plate 25 to slide upward on the vertical plate 2 through the sliding plate 24. At this time, the transmission mechanism will be triggered to move, and the horizontal plate 25 will drive the connecting plate 3 to deflect through the connecting rod 26, causing the material support plate 4 to tilt.

[0056] Please refer to it again. Figure 4 The transmission mechanism includes a transmission shaft 28 rotatably mounted on the base 1, and the transmission shaft 28 is provided with a spiral groove. A transmission rod 27 is fixed to the side of the horizontal plate 25, and a ball bearing that rolls and engages with the spiral groove is movably provided at the end of the transmission rod 27. The transmission shaft 28 and the horizontal shaft 30 are connected by a bevel gear set 29.

[0057] In detail, the bevel gear set 29 includes a first bevel gear fixedly mounted on the drive shaft 28 and a second bevel gear fixedly mounted on the horizontal shaft 30 at one end facing the drive shaft 28, and the second bevel gear meshes with the first bevel gear.

[0058] When the horizontal plate 25 slides upward on the vertical plate 2, the transmission rod 27 rises along with the horizontal plate 25. Correspondingly, the ball bearings on the transmission rod 27 drive the transmission shaft 28 to rotate through the spiral groove. Then, the transmission shaft 28 drives the horizontal shaft 30 to rotate through the bevel gear set 29, so that the scraper 6 performs a scraping action on the powder.

[0059] Please refer to it again. Figure 5 and Figure 8 The elastic triggering mechanism includes a cylinder 19 slidably disposed on the side of the upright arm 9, a telescopic rod 20 slidably fitted with the cylinder 19, and a first cylindrical spring 21 and a second cylindrical spring 22 sleeved on the outer periphery of the telescopic rod 20. A ring 23 slidably connected to the inner wall of the cylinder 19 is also fixed on the telescopic rod 20. The first cylindrical spring 21 and the second cylindrical spring 22 are respectively connected to the two sides of the ring 23, and their tail ends abut against the inner wall of the cylinder 19. A column 38 is also fixed on the outer wall of the cylinder 19. One end of the telescopic rod 20 is fixed to the sliding plate 24, and the other end of the telescopic rod 20 and the column 38 are connected to a limiting structure disposed on the base 1.

[0060] The limiting structure includes a limiting plate 18 fixedly installed on the base 1. The limiting plate 18 is provided with a rectangular groove and an inclined groove 1805. The end of the telescopic rod 20 away from the sliding plate 24 extends into the rectangular groove and is slidably connected to the limiting plate 18. The column 38 extends into the inclined groove 1805 and is slidably connected to the limiting plate 18. The rectangular groove includes a first horizontal section 1801, a first vertical section 1802, a second horizontal section 1803, and a second vertical section 1804 connected together.

[0061] Furthermore, a mounting base (not labeled in the figure) is fixed on the upright arm 9, and the cylinder 19 is slidably disposed on the mounting base. Specifically, a guide groove (not labeled in the figure) is provided on the mounting base, and a guide block (not labeled in the figure) fixed to the cylinder 19 is slidably fitted in the guide groove.

[0062] Starting from the state shown in the attached figure, the end of the telescopic rod 20 away from the sliding plate 24 is located at the connection between the first horizontal section 1801 and the second vertical section 1804, and the column 38 is located at the end of the inclined groove 1805 near the second vertical section 1804.

[0063] When the vertical arm 9 moves toward the vertical plate 2 along the guide rail 7, the end of the telescopic rod 20 away from the sliding plate 24 moves along the first horizontal section 1801, and the column 38 slides along the inclined groove 1805, thereby causing the cylinder 19 to give way, causing the cylinder 19 to move upward, and the first column spring 21 is compressed.

[0064] After the rolling roller 5 moves to the end of its stroke, the end of the telescopic rod 20 away from the sliding plate 24 reaches the connection between the first horizontal section 1801 and the first vertical section 1802. At this time, the first cylindrical spring 21 will rebound, causing the telescopic rod 20 to move upward on the cylinder 19 until the end of the telescopic rod 20 away from the sliding plate 24 reaches the connection between the first vertical section 1802 and the second horizontal section 1803. At the same time, the telescopic rod 20 drives the horizontal plate 25 to slide upward on the vertical plate 2 through the sliding plate 24, the rolling roller 5 is lifted, the material support plate 4 is tilted, and the scraper 6 performs a scraping action on the powder.

[0065] Subsequently, the drive motor 8 changes its driving direction, causing the upright arm 9 to move back along the guide rail 7. At this time, the end of the telescopic rod 20 away from the sliding plate 24 moves along the second horizontal section 1803, and the column 38 causes the cylinder 19 to move downward through the inclined groove 1805, and the second column spring 22 is compressed.

[0066] After the upright arm 9 returns to its original position, the end of the telescopic rod 20 away from the sliding plate 24 moves to the connection between the second horizontal section 1803 and the second vertical section 1804. At this time, the second cylindrical spring 22 rebounds, causing the telescopic rod 20 to move downward on the cylinder 19. The end of the telescopic rod 20 away from the sliding plate 24 returns to the connection between the first horizontal section 1801 and the second vertical section 1804. The rolling roller 5 moves down, the material support plate 4 returns to a horizontal state, and the scraper 6 returns to its original position on the material support plate 4.
