Description

Technical Field

[0001] The invention belongs to the field of aluminum hydroxide production, and in particular relates to an ultrafine aluminum hydroxide production and processing device. Background Art

[0002] Ultrafine aluminum hydroxide refers to aluminum hydroxide powder with a particle size of micrometer or nanometer level, which can be prepared by a variety of methods, including precipitation method, sol-gel method, hydrothermal synthesis method, etc. These methods usually involve the reaction of aluminum salt solution with alkaline substances to form aluminum hydroxide precipitate, and then obtain ultrafine powder through further treatment (such as drying, crushing, etc.).

[0003] During the production process, the aluminum hydroxide particles produced need to be mixed with water for pulping. Pulping can evenly disperse the aluminum hydroxide particles in the liquid medium to avoid agglomeration between particles. This is very important for the subsequent drying process, because evenly dispersed particles can be heated more evenly during drying, thereby reducing the problem of uneven drying. At present, the main method for pulping ultrafine aluminum hydroxide is to pour aluminum hydroxide particles into water and stir them.

[0004] At present, the conventional stirring method is used to slurry ultrafine aluminum hydroxide, which has the following defects: 1. Since the particle size of ultrafine aluminum hydroxide particles is very small, it is difficult to disperse the ultrafine aluminum hydroxide particles that are partially agglomerated by traditional stirring operations, and it takes a longer time to ensure that the ultrafine aluminum hydroxide is fully slurried; 2. After a period of slurrying, it is usually necessary to sample the internal slurry to detect whether it is sufficiently slurried. If the slurry is not sufficiently slurried, it is necessary to continue slurrying. It may be necessary to repeatedly sample and test multiple times to determine whether the slurry is sufficient. The operation is cumbersome and time-consuming. 3. The previous process of ultrafine aluminum hydroxide particles before slurrying is washing, and slurrying is performed after washing and filtration. Therefore, there is still a small amount of sewage in the ultrafine aluminum hydroxide particles that has not been completely filtered. Such ultrafine aluminum hydroxide particles containing a small amount of water may affect the slurrying quality when entering the slurrying tank for slurrying. Summary of the invention

[0031] The following is combined with Figure 1-9 This application is further described in detail.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3A superfine aluminum hydroxide production and processing device includes a pulping tank 1 with a water injection pipe 11 on the outer wall of the upper end, a first stirring frame 2 is rotatably arranged inside the pulping tank 1, a pressure detection component 3 is arranged on the first stirring frame 2, a vibration mechanism 4 for cyclically driving the first stirring frame 2 to vibrate is arranged above the first stirring frame 2, a driving mechanism 5 for simultaneously driving the first stirring frame 2 and the vibration mechanism 4 is arranged at the lower end of the pulping tank 1, and a storage bin 6 is also fixedly arranged at the upper end of the pulping tank 1. The ultrafine aluminum hydroxide raw material is fed from the storage bin 6 into the pulping tank 1, and at the same time, an external water supply device injects a certain amount of water through the water injection pipe 11 on the outer wall of the pulping tank 1, and then the first stirring frame 2 is driven by the driving mechanism 5 to rotate for stirring. During the stirring process, the driving mechanism 5 can also drive the vibration mechanism 4 to work, and cyclically impact the first stirring frame 2 vertically, so that the first stirring frame 2 vibrates. While rotating and stirring, the first stirring frame 2 can also have a certain vibration effect on the slurry, thereby improving the pulping quality and facilitating the dispersion of ultrafine aluminum hydroxide particles. In the entire working process, multiple groups of pressure detection components 3 are at different depths and rotate with the first stirring frame 2, and the pressure of the slurry on the pressure detection component 3 during the stirring process is detected in real time. When the pressure detected by all pressure detection components 3 drops to the threshold, the external controller can remind the staff to sample and detect the slurry, thereby reducing the number of sampling tests and more accurately judging whether the slurry is sufficiently pulped.

[0033] See also Figure 1 , Figure 2 , Figure 7-Figure 9The vibration mechanism 4 includes an isolation cover 41 fixedly arranged on the inner wall of the upper top of the pulping tank 1, the upper end of the first stirring frame 2 movably passes through the lower bottom of the isolation cover 41 and is fixedly connected with a pressure block 42, a rotating shaft 43 is movably inserted on the pressure block 42, the upper end of the rotating shaft 43 is rotatably connected to the inner wall of the upper top of the isolation cover 41, and a collision block 44 is movably sleeved on the surface of the rotating shaft 43, and a gear linkage assembly 45 for driving the collision block 44 to move upward is arranged between the rotating shaft 43, the isolation cover 41 and the collision block 44. The gear linkage assembly 45 includes a gear 1 451 fixedly arranged on the upper end of the rotating shaft 1 43, and a rotating shaft 2 452 is rotatably arranged on the left and right inner walls of the isolation cover 41, and a gear 2 453 and a gear 3 454 are fixedly arranged on the rotating shaft 2 452, and the gear 3 454 is a half gear, and the left and right gears 2 453 are meshed with the upper gear 1 451, and the left and right sides of the impact block 44 are fixedly arranged with tooth plates 455, and the left and right tooth plates 455 are staggered and symmetrically distributed on the impact block 44, and the two gears 3 454 are respectively meshed with the tooth plates 455 on the left and right sides of the impact block 44. A connecting plate 46 rotatably connected to the rotating shaft 1 43 is fixedly arranged inside the upper end of the isolation cover 41, and four spring telescopic rods 1 47 are fixedly arranged at the bottom of the connecting plate 46, and the lower ends of the four spring telescopic rods 1 47 are respectively fixedly connected to the upper parts of the four corners of the impact block 44.

[0034] In order to be able to oscillate the ultrafine aluminum hydroxide slurry while the first stirring frame 2 is stirring the slurry, when the driving mechanism 5 drives the first stirring frame 2 to rotate, the driving mechanism 5 can synchronously drive the rotating shaft 1 43 to rotate, and the rotation of the rotating shaft 1 43 can drive the gear 1 451 to rotate, so that the gear 2 453 below the left and right sides of the gear 1 451 rotates at the same time, and the rotation of the gear 2 453 can drive the corresponding gear 3 454 to rotate, and the gear 3 454 is meshed with the corresponding tooth plate 455 on the impact block 44, so that the left and right gears 454 can cooperate with the corresponding tooth plate 455 to drive the impact block 44 It moves upward, and after rising to a certain height, since gear three 454 is a half gear, when the notch part of gear three 454 is aligned with the tooth plate 455, the impact block 44 will eventually lose its upward driving force, and fall rapidly under the action of its own gravity and the spring telescopic rod 47, and finally collide with the pressure block 42. After the pressure block 42 is hit vertically downward, the first stirring frame 2 will vibrate (the specific impact force is adjusted according to the gravitational potential energy in the pressure block 42 and the elastic potential energy of the spring telescopic rod 47), so that the first stirring frame 2 can vibrate the slurry when rotating.

[0035] See also Figure 1 , Figure 3 and Fig. 9The first stirring frame 2 includes a main shaft 21 connected to a driving mechanism 5, and four groups of stirring nets 22 composed of a plurality of stirring rods are fixedly arranged on the outer wall of the main shaft 21. The interior of the main shaft 21 is a hollow structure, and a rotating shaft 43 movably penetrates the interior of the main shaft 21 and is connected to the driving mechanism 5. The rotating shaft 43 movably penetrates the main shaft 21, so that the rotating shaft 43 can rotate relative to the main shaft 21.

[0036] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The driving mechanism 5 includes a rotating seat 51 fixedly arranged on the inner wall of the lower end of the pulping tank 1, a driving motor 52 is fixedly arranged at the bottom of the pulping tank 1, and the output shaft of the driving motor 52 is fixedly connected to the rotating seat 51. A rectangular active cavity 511 is opened inside the rotating seat 51, and a rectangular slide seat 53 is slidably arranged in the active cavity 511. The lower end of the main shaft 21 movably passes through the upper part of the rotating seat 51 and is fixedly connected to the slide seat 53, and a buffer spring 54 is sleeved between the bottom of the slide seat 53 and the bottom inner wall of the active cavity 511. The lower end of the rotating shaft 43 movably passes through the slide seat 53 and is fixedly connected to the bottom inner wall of the active cavity 511, and the buffer spring 54 is sleeved on the outside of the rotating shaft 43.

[0037] In order to be able to simultaneously drive the first stirring frame 2 and the rotating shaft 43 to rotate through a single driving mechanism 5, when the driving motor 52 drives the rotating seat 51 to rotate, the rotating seat 51 can drive the slide 53 inside it to rotate, and the rotation of the slide 53 can drive the main shaft 21 on the first stirring frame 2 to rotate, thereby driving the first stirring frame 2 to rotate. At the same time, the rotation of the rotating seat 51 will also drive the rotating shaft 43 fixedly connected to it to rotate. The rotation of the rotating shaft 43 can cooperate with the gear linkage assembly 45 to drive the impact seat to move upward and impact the pressure block 42 at the upper end of the first stirring frame 2, so that the first stirring frame 2 has a shaking effect on the slurry. At the same time, the bottom of the slide 53 is connected by a buffer spring 54, which can reduce the vibration of the first stirring frame 2 when it vibrates, ensuring that the slurry in the pulping tank 1 is shaken while reducing the vibration effect on the pulping tank 1 itself, and having better stability.

[0038] See also Figure 1 and Figure 3 The pressure detection assembly 3 is arranged into four groups. The four groups of pressure detection assemblies 3 are fixedly arranged on the stirring net 22 in a stepped manner. The pressure detection assembly 3 includes a fixed plate fixedly arranged on two adjacent stirring rods on the stirring net 22, and a pressure detector is fixedly arranged on the fixed plate.

[0039] In order to facilitate the judgment of whether the slurry has started to disperse, four groups of pressure detectors at different heights are installed on one of the stirring nets 22. When the first stirring frame 2 drives the pressure detection component 3 to rotate, since the ultrafine aluminum hydroxide particles have just been added to the pulping tank 1, the pressure detector on the pressure detection component is initially subject to great resistance from the slurry. With the continuous stirring of the first stirring frame 2, the slurry in the pulping tank 1 is gradually mixed and dispersed, and the resistance of the slurry to the pressure detector on the pressure detection component 3 will gradually decrease. When the pressures on the four pressure detectors are all less than the threshold value, it means that the slurry has been basically fully dispersed. At this time, the staff can be reminded through the external controller to take samples to confirm whether the slurry is fully beaten. This can significantly reduce the number of sampling times for the staff and save time.

[0040] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 The storage bin 6 is internally provided with a second stirring frame 7 for rotation. The second stirring frame 7 includes a main shaft 2 71 whose lower end is fixedly connected to the rotating shaft 1 43. A stirring net 2 72 composed of a plurality of stirring rods is fixedly connected to the outer wall of the main shaft 2 71. A pushing plate 2 73 is provided at the lower end of the stirring net 2 72. The bottom inner wall of the storage bin 6 is provided with a slope surface, and the lower end of the pushing plate 2 73 is movably fitted with the slope surface. An annular groove 61 is provided on the inner wall of the lower end of the storage bin 6. An elastic mounting strip 62 is movably embedded in the annular groove 61. A plurality of water filter holes 1 are provided on the surface of the elastic mounting strip 62. A water filter cotton layer 63 is fixedly provided on the inner circle of the elastic mounting strip 62. A plurality of water filter holes 2 that penetrate the storage bin 6 are provided on the inner wall of the annular groove 61. A water storage tank 64 is provided on the top surface of the pulping tank 1. A drainage pipe 65 is connected to one side of the water storage tank 64. A discharge port connected to the storage bin 6 is provided at the top of the upper end of the pulping tank 1, and a sealing plate 14 is movably arranged in the discharge port, and an electric push rod 15 is fixedly arranged on the inner wall of the top of the upper end of the pulping tank 1, and the telescopic end of the electric push rod 15 is fixedly connected to the sealing plate 14.

[0041] In order to further reduce the residual sewage content of the ultrafine aluminum hydroxide raw materials to be pulped in the previous process, when the rotating shaft 1 43 rotates, the main shaft 2 71 can be driven to rotate synchronously, so that the stirring net 2 72 rotates in the storage bin 6, so that the ultrafine aluminum hydroxide raw materials in the storage bin 6 can be fully turned over, so that the water mixed therein can flow downward better, and the sewage flows along the slope surface toward the inner wall of the lower end of the storage bin 6. After being filtered by the water filter cotton layer 63 on the elastic mounting strip 62, the sewage is discharged through the water filter hole 1 on the elastic mounting strip 62 and the water filter hole 2 on the inner wall of the annular groove 61, and enters the water storage tank 64. During the subsequent unloading, the electric push rod 2 15 is contracted to move the sealing plate 2 14 out of the unloading port, so that the ultrafine aluminum hydroxide raw materials can fall into the pulping tank 1, and the push plate 2 73 can rotate at the same time, which is convenient for unloading the raw materials in the storage bin 6.

[0042] See also Figure 1 , Figure 3 , Figure 4 , the lower end of the mixing net 22 is fixedly connected with two spring telescopic rods 23, and the lower ends of the two spring telescopic rods 23 are fixedly connected with a push plate 24. The bottom of the lower end of the pulping tank 1 is provided with a discharge hole connected with the interior thereof, and two sealing plates 12 are movably provided in the discharge hole, and two electric push rods 13 are fixedly provided at the bottom of the pulping tank 1, and the telescopic ends of the electric push rods 13 are fixedly connected with the corresponding sealing plates 12, and a sampling port 121 with a sealing plug is provided on the surface of any sealing plate 12. The spring telescopic rods 23 cooperate with the push plate 24, which can not only facilitate the discharge of the pulp after pulping, but also support the first stirring frame 2, so that the first stirring frame 2 is more stable when rotating and vibrating.

[0043] During the specific operation, the ultrafine aluminum hydroxide raw material is fed from the storage bin 6 into the pulping tank 1, and at the same time, the external water supply equipment injects a certain amount of water through the water injection pipe 11 on the outer wall of the pulping tank 1, and then the first stirring frame 2 is driven by the driving mechanism 5 to rotate and stir. During the stirring process, the driving mechanism 5 can also drive the vibration mechanism 4 to work, so that the impact block 44 rises cyclically and then falls rapidly, and cyclically impacts the first stirring frame 2 vertically, so that the first stirring frame 2 vibrates. The first stirring frame 2 can also have a certain shock effect on the slurry while rotating and stirring, which is conducive to dispersing the ultrafine aluminum hydroxide particles and improving the pulping quality and efficiency. In addition, during the entire working process, multiple groups of pressure detection components 3 are at different depths and rotate with the first stirring frame 2, and the pressure of the slurry on the pressure detection component 3 during the stirring process is detected in real time. When the pressure detected by all pressure detection components 3 drops to the threshold, the external controller can remind the staff to sample and test the slurry, reducing the number of sampling tests and more accurately judging whether the slurry is fully beaten. After the pulping is completed, the pulp is discharged through the discharge hole inside the lower end of the pulping tank 1 and transferred to the next step for processing.
