Description

TECHNICAL FIELD

[0001] The application belongs to the field of aluminum sol production, and particularly relates to a reactor for aluminum sol production. BACKGROUND

[0002] Aluminum sol is a colloidal solution mainly composed of aluminum oxide, which has good adhesion, dispersibility and high temperature resistance, and is widely used in catalyst carriers, ceramic product binders, refractory material binders and other fields. Its production process usually needs to neutralize the reaction of aluminum salt (such as aluminum chloride, aluminum nitrate, etc.) and alkali source (such as ammonia, sodium hydroxide, etc.) in the reactor, and fully mix the raw materials through stirring to ensure uniform reaction and finally form a stable sol system.

[0003] In the production of aluminum sol, the uniformity of raw material mixing is one of the core factors determining the quality of the product. If the raw materials are not fully mixed, it will lead to excessive or insufficient local reaction, resulting in uneven particle size distribution of sol, large viscosity fluctuation, poor stability and other problems, which seriously affect the subsequent application effect.

[0004] The traditional reactor for aluminum sol production mostly adopts a single rotary stirring structure, that is, the stirring rod is fixed on the rotating shaft and makes one-way circular motion with the rotating shaft. However, due to the gradual increase of the viscosity of aluminum sol raw materials during the reaction process (especially in the middle and late stages of the reaction), the single-direction rotary stirring will make the raw materials flow along the fixed track, forming a "vortex dead zone" - the areas at the edge and bottom of the reactor and difficult to be reached by the stirring rod are prone to raw material deposition or agglomeration, resulting in that the raw materials in these areas cannot be fully contacted with the main materials, and the reaction progress lags behind. For example, when the stirring rod only makes horizontal rotation, the raw materials at the bottom of the reactor are difficult to be fully stirred due to the influence of gravity, and high-concentration deposits are easily formed; while the raw materials at the upper part of the reactor may have local unreacted aluminum salt particles due to insufficient stirring intensity, which eventually leads to the presence of impurities or uneven performance in the product. SUMMARY

[0005] The purpose of the present application is to provide a reactor for aluminum sol production to solve the problem of the traditional reactor for aluminum sol production which mostly adopts a single rotary stirring structure and has unsatisfactory reaction effect.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] A reactor for aluminum sol production, comprising: a reactor body and a reactor cover located at the top of the reactor body, a rotating shaft movably arranged in the reactor body, a plurality of stirring assemblies arranged on the rotating shaft, and a rotary drive arranged at the input end of the rotating shaft.

[0008] Each of the stirring assemblies comprises a stirring rod arranged on both sides of the rotating shaft, and the stirring rod and the rotating shaft are connected through a swing mechanism.

[0009] The swing mechanism includes a fixed rod movably disposed within a rotating shaft, shafts movably disposed on both sides of the rotating shaft, the shafts being fixedly connected to a stirring rod, and rotating wheels movably disposed within the rotating shaft on both sides of the fixed rod. The two rotating wheels are respectively connected to the two shafts via transmission components, and bevel gears are disposed on the rotating wheels. A bevel gear block is disposed on both sides of the fixed rod.

[0010] It also includes a quick-release mechanism, which includes an opening at the top of the lid, a sealing cap inside the opening, and a rotating shaft passing through and movably connected to the sealing cap.

[0011] Preferably, the two bevel gear blocks are located on one side of the fixed rod at the top of the wheel and on the other side of the fixed rod at the bottom of the wheel, respectively, and the bevel gear meshes with the bevel gear blocks.

[0012] Preferably, sleeves are movably provided on both sides of the rotating shaft around the shaft, and baffles are provided at the front ends of the sleeves at both ends of the shaft.

[0013] Preferably, a telescopic hose is provided between the front end of the sleeve and the stirring rod.

[0014] Preferably, a bidirectional lead screw is movably disposed inside the fixed rod, and a movable groove is provided on the fixed rod on one side of each of the two conical tooth blocks. Two movable blocks are threaded on the bidirectional lead screw, and a second conical tooth block is provided on each movable block. The two movable grooves are respectively located on the periphery of the two second conical tooth blocks.

[0015] Preferably, the front end of the bidirectional lead screw passes through the fixed rod, the second bevel gear engages with the bevel gear, and a bracket is provided on the top of the sealing cover.

[0016] Preferably, a second gear is provided on the rotating shaft at the top of the sealing cover, the rotary drive is located at the top of the lid, and a first gear is provided at the output end of the rotary drive, the first gear meshing with the second gear.

[0017] Preferably, a swing arm is provided on the fixed rod at the top of the rotating shaft, a movable rod is movably provided on the swing arm, a threaded cylinder is provided at the bottom of the movable rod, a threaded block is provided at the top of the sealing cover, and the threaded block is threadedly connected to the threaded cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention connects the stirring rod to the rotating shaft via a swing mechanism. While the rotating drive unit drives the rotating shaft to rotate, the swing mechanism drives the stirring rod to swing back and forth during the rotation. This combined rotation and swing motion breaks the "vortex dead zone" of traditional single-rotation stirring, increases the contact angle and range between the stirring rod and the raw materials, and can effectively agitate the raw materials at the edge and bottom of the reactor, avoiding local agglomeration or deposition. This significantly improves the mixing uniformity of the aluminum sol raw materials, ensures that the reaction proceeds fully, and fundamentally solves the problem of unstable product quality caused by the single stirring direction in traditional reactors.

[0020] This invention utilizes a quick-release mechanism, eliminating the need to completely disassemble the vessel lid when cleaning, replacing, or repairing the stirring assembly. Simply open the sealing cover, fold the stirring rod to reduce its footprint, and the stirring assembly can be removed from the vessel through the opening. This significantly simplifies the disassembly and assembly process, reduces equipment downtime for maintenance, and improves production continuity. Attached Figure Description

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] As attached Figure 1 To be continued Figure 6 As shown:

[0033] Example 1: This example provides a reactor for producing aluminum sol, including: a vessel body 1 and a vessel cover 2 located on top of the vessel body 1. A rotating shaft 3 is movably arranged inside the vessel body 1. Multiple sets of stirring components are arranged on the rotating shaft 3. A rotary drive 6 is arranged at the input end of the rotating shaft 3.

[0034] Each stirring assembly includes stirring rods 4 disposed on both sides of the rotating shaft 3, and the stirring rods 4 are connected to the rotating shaft 3 by a swing mechanism 5;

[0035] The swing mechanism 5 includes a fixed rod 506 movably disposed within the rotating shaft 3. Shafts 501 are movably disposed on both sides of the rotating shaft 3. The shafts 501 are fixedly connected to the stirring rod 4. Rotary wheels 502 are movably disposed within the rotating shaft 3 on both sides of the fixed rod 506. The two rotary wheels 502 are respectively connected to the two shafts 501 through a transmission component 507. A bevel gear 508 is disposed on the rotary wheel 502. A bevel gear block 509 is disposed on both sides of the fixed rod 506.

[0036] It also includes a quick-release mechanism 7, which includes an opening 704 located at the top of the vessel lid 2, a sealing cover 701 located inside the opening 704, and a rotating shaft 3 passing through the sealing cover 701 and being movably connected to it.

[0037] The fixed rod 506 is rotatably connected to the rotating shaft 3 via a bearing and can rotate around its own axis.

[0038] Rotary seats are provided on both sides of the rotating shaft 3. The shaft 501 is rotatably connected to the through hole of the rotating seat through the bearing and can rotate around its own axis.

[0039] The rotating wheel 502 is rotatably connected to the inner wall of the rotating shaft 3 via a bearing, and can rotate around its own axis.

[0040] Specifically, the two bevel gear blocks 509 are located on one side of the fixing rod 506 at the top of the rotating wheel 502 and on the other side of the fixing rod 506 at the bottom of the rotating wheel 502, respectively, and the bevel gear 508 meshes with the bevel gear blocks 509.

[0041] In this embodiment, the transmission component 507 is a transmission belt, and the wheel 502 and the shaft 501 are both fixedly connected to the transmission belt by fixing blocks. The sealing cover 701 and the kettle cover 2 are connected by bolts.

[0042] During operation, the rotary drive 6 rotates, which drives the rotating shaft 3 to rotate inside the vessel 1. Multiple sets of stirring components on the rotating shaft 3 rotate synchronously with the rotating shaft 3, thus initially realizing the stirring and mixing of aluminum sol raw materials.

[0043] During the stirring process, the operator fixes the position of the fixed rod 506 so that it and the bevel gear block 509 on it do not rotate with the rotating shaft 3. When the rotating shaft 3 rotates, it drives the rotating wheel 502 on it to rotate, so that the rotating wheel 502 revolves around the axis of the rotating shaft 3. The bevel gear 508 on the rotating wheel 502 meshes with the bevel gear block 509 on both sides of the fixed rod 506, so that the rotating wheel 502 rotates on its own axis during the revolution. Then, through the transmission component 507, it drives the shaft 501 to rotate synchronously, so as to drive the stirring rod 4 to rotate and swing up and down, thereby increasing the stirring range of the stirring rod 4. It can stir the aluminum sol raw material in the reactor 1 in multiple directions and angles, which greatly improves the uniformity of the raw material mixing, avoids the problem of insufficient local mixing, and improves the production quality of aluminum sol.

[0044] The tooth surface of the bevel gear 509 is inclined and matches the tooth surface of the bevel gear 508. The tooth direction is distributed along the axial direction of the fixed rod 506. The tooth directions of the two bevel gears 509 are opposite (corresponding to the clockwise and counterclockwise rotation of the rotating wheel 502 respectively). When the rotating wheel 502 revolves with the rotating shaft 3, the bevel gear 508 alternately meshes with the two bevel gears 509, generating a rotational motion that alternates between forward and reverse rotation.

[0045] The transmission ratio between the rotor 502 and the shaft 501 is 1:1, ensuring that the rotation angle of the rotor 502 is directly transmitted to the shaft 501, driving the stirring rod 4 to achieve reciprocating oscillation of ±30° (default initial angle).

[0046] Specifically, since the two bevel gear blocks 509 are located on one side of the fixed rod 506 at the top of the rotating wheel 502 and the other side of the fixed rod 506 at the bottom of the rotating wheel 502, the bevel gear 508 will mesh with the two bevel gear blocks 509 respectively as it revolves with the rotating shaft 3, depending on its current rotation position. Since the two bevel gear blocks 509 are located at the top and bottom of the rotating wheel 502 respectively, the bevel gear 508 will frequently switch between forward and reverse rotation as it revolves with the rotating shaft 3, thereby achieving frequent up and down swinging of the stirring rod 4. The two rotating wheels 502 corresponding to the stirring rods 4 on both sides of the rotating shaft 3 are located on both sides of the fixed rod 506, so that the bevel gears 508 on the two rotating wheels 502 will mesh with the two bevel gear blocks 509 at the same time, so that the two stirring rods 4 swing in different directions, further improving the stirring effect.

[0047] The stirring rod 4 is driven to swing in the direction of the rotating shaft 3 by the swing mechanism 5, so that the radial dimension of the stirring assembly is reduced to the diameter range of the opening 704, so that it can be taken out through the opening 704.

[0048] Specifically, by setting an opening 704 on the vessel lid 2, when it is necessary to remove the rotating shaft 3 for cleaning, replacement, or maintenance of the stirring rod 4, simply stop the rotating drive component 6, and then the operator rotates the fixed rod 506, causing it to drive the conical tooth block 509 to rotate. This drives the stirring rod 4 to swing while the rotating shaft 3 remains stationary, until the stirring rod 4 shrinks to the area covered by the opening 704, reducing the space occupied by the stirring mechanism. Subsequently, the operator separates the sealing cover 701 from the vessel lid 2 and pulls it upwards, allowing the stirring mechanism to be pulled out of the device through the opening 704. The stirring mechanism can be disassembled, cleaned, or repaired without opening the vessel lid 2, achieving rapid disassembly and assembly, reducing equipment maintenance time and costs, and ensuring the continuous and stable operation of the equipment.

[0049] Specifically, sleeves 503 are movably installed on both sides of the rotating shaft 3 around the shaft 501, and baffles 504 are installed at the front ends of the sleeves 503 at both ends of the shaft 501.

[0050] The sleeve 503 provides support and protection for the shaft 501, and the baffle 504 supports and limits the stirring rotation direction of the stirring rod 4, preventing the shaft 501 from loosening or bending due to the resistance generated during the stirring operation of the stirring rod 4. The sleeve 503 is movably connected to the rotating shaft 3. When the stirring rod 4 rotates and swings, it will generate an oblique pushing force on the sleeve 503 when it contacts it, pushing it towards the rotating shaft 3 without affecting the swing of the stirring rod 4. This achieves maximum protection for the shaft 501 without affecting the swing of the stirring rod 4.

[0051] An elastic element, such as a spring, is provided between the sleeve 503 and the rotating shaft 3 to accumulate elastic potential energy when the stirring rod 4 pushes it toward the rotating shaft 3, and to automatically reset when the stirring rod 4 swings in the opposite direction.

[0052] Specifically, a telescopic hose 505 is provided between the front end of the sleeve 503 and the stirring rod 4.

[0053] The telescopic hose 505 elastically expands and contracts when the stirring rod 4 swings, compensating for the angular change between the shaft 501 and the stirring rod 4. Simultaneously, it prevents raw materials inside the vessel body 1 from seeping into the equipment through the gap between the shaft 501 and the rotating shaft 3, thus providing a dynamic seal. This protects the transmission components inside the rotating shaft 3 from corrosion or contamination by the raw materials, providing both sealing and buffering functions and extending the equipment's service life. The telescopic hose 505 is made of silicone, possessing excellent high-temperature resistance, ozone resistance, UV resistance, and chemical inertness. It is widely used in various corrosive environments and exhibits good resistance to most acids, alkalis, salts, and non-polar solvents. It can withstand the chemical properties of aluminum sol without being corroded, ensuring sealing performance and service life.

[0054] Example 2: This example is basically the same as the previous example, except that a bidirectional lead screw 707 is movably arranged inside the fixed rod 506, and movable grooves 706 are provided on the fixed rod 506 on the side of the two conical tooth blocks 509. Two movable blocks 708 are threaded on the bidirectional lead screw 707, and conical tooth blocks 709 are provided on the movable blocks 708. The two movable grooves 706 are located on the periphery of the two conical tooth blocks 709 respectively.

[0055] During operation, rotating the bidirectional lead screw 707 causes two movable blocks 708 to move towards or away from each other within the fixed rod 506. The second conical tooth block 709 on the movable block 708 moves within the movable groove 706. When the second conical tooth block 709 moves to the side of the corresponding first conical tooth block 509 and engages with it, it meshes with the bevel gear 508 during the rotation of the rotating shaft 3. This extends the rotation time and angle of the rotating wheel 502, thereby adjusting the swing amplitude of the stirring rod 4. This adapts to the stirring requirements of aluminum sol raw materials with different viscosities and ratios, enhancing the equipment's versatility. For example, when the opening 704 at the top of the lid 2 is small, normal operation only engages the first conical tooth block 509 with the bevel gear 508, controlling the swing amplitude of the stirring rod 4 and preventing it from getting too close to the rotating shaft 3, which would reduce the stirring range. When maintenance of the stirring mechanism is required, the position of the second conical tooth block 709 is adjusted to engage with the bevel gear 508 in the working position, allowing the stirring rod 4 to swing within the coverage area of ​​the opening 704 for convenient use.

[0056] The movable groove 706 not only provides movement space for the second bevel gear block 709, but its edge also serves as a limit for the movable block 708, preventing the movable block 708 from shifting when the bidirectional lead screw 707 rotates, ensuring that the second bevel gear block 709 and the bevel gear 508 always maintain the correct meshing state, and ensuring the stability of the adjustment function.

[0057] Specifically, the front end of the bidirectional lead screw 707 passes through the fixed rod 506, the bevel gear block 709 meshes with the bevel gear 508, and a bracket 705 is provided on the top of the sealing cover 701.

[0058] The fixed rod 506 is passed through the front end of the bidirectional lead screw 707, allowing the operator to adjust the bevel gear block 709 at the top of the device.

[0059] Workers can pull the stirring mechanism out of the vessel body 1 by holding the bracket 705 or connecting the bracket 705 to the hoisting equipment.

[0060] Specifically, a second gear 703 is provided on the rotating shaft 3 at the top of the sealing cover 701, and the rotary drive 6 is located at the top of the vessel cover 2. A first gear 702 is provided at the output end of the rotary drive 6, and the first gear 702 meshes with the second gear 703.

[0061] The rotary drive 6 includes, but is not limited to, a servo motor. When it is working, it drives the output shaft gear 702 to rotate, and then drives the rotating shaft 3 to rotate through the meshing of gear 702 and gear 703 to perform stirring. When it is necessary to remove the stirring mechanism for maintenance, the sealing cover 701 can be lifted directly to remove the stirring mechanism. When reinstalling after maintenance, it is only necessary to mesh gear 702 and gear 703. There is no need to remove the rotary drive 6 together. Partial disassembly and assembly can be performed, which greatly improves work efficiency and reduces equipment downtime.

[0062] Specifically, a swing arm 5061 is provided on the fixed rod 506 at the top of the rotating shaft 3, a movable rod 5062 is movably provided on the swing arm 5061, a threaded cylinder 5063 is provided at the bottom of the movable rod 5062, and a threaded block 5064 is provided at the top of the sealing cover 701. The threaded block 5064 is threadedly connected to the threaded cylinder 5063.

[0063] The swing arm 5061 is provided with a through hole, and the movable rod 5062 passes through the through hole and is slidably connected to the swing arm 5061, and can move along the axial direction of the through hole and rotate around its own axis.

[0064] The threaded cylinder 5063 limits the position of the movable rod 5062 through its threaded connection with the threaded block 5064. In turn, the movable rod 5062 limits the position of the swing arm 5061 and the fixed rod 506, so that the fixed rod 506 will not rotate during the stirring operation, thus achieving the swinging effect of the stirring rod 4. When the stirring mechanism needs to be removed for maintenance, simply rotate the movable rod 5062 to separate the threaded cylinder 5063 at its bottom from the threaded block 5064, and then the fixed rod 506 can be moved by the swing arm 5061 to rotate on the rotating shaft 3.

[0065] Example 3: This example is basically the same as the previous example, except that the transmission component 507 is a gear set that meshes with each other, the shaft 501 and the rotating wheel 502 are connected by meshing gears, and by controlling the number of intermediate transmission gears, the swing angle of the stirring rods 4 on both sides of the rotating shaft 3 can be made consistent.

[0066] Example 4: This example is basically the same as the previous example, except that the stirring rods 4 of the multiple stirring components are staggered along the axis of the rotating shaft 3, and the circumferential angle of the two adjacent stirring rods 4 differs by 60°, so as to avoid mutual interference when the upper and lower stirring rods 4 swing. It is suitable for the vessel body 1 with a long diameter but low height.
