Description

Technical Field

[0001] The invention relates to the technical field of aluminum oxide production equipment, in particular to a grinding processing device for high-purity nano aluminum oxide. Background Art

[0002] In the field of modern materials science, high-purity nano-alumina is widely used in coatings, ceramics, electronics, medicine and other industries due to its excellent physical and chemical properties. Traditional high-purity nano-alumina grinding and processing devices mainly rely on mechanical grinding methods, which use grinding media to physically contact with alumina particles to achieve refinement. However, the prior art often faces the following technical problems during the grinding process: First, the efficiency of traditional grinding equipment is low, and it is difficult to meet the growing demand for high purity and particle size uniformity. Due to the high hardness of alumina particles, particle aggregation and re-agglomeration are prone to occur during the grinding process, resulting in uneven particle size distribution of the final product, affecting the overall quality of alumina. Secondly, during the grinding process, the clogging problem of the filter often affects the fluidity of the material, reduces the continuity and stability of production, and further increases the maintenance cost and downtime of the equipment.

[0020] Preferably, the outer side of the driving gear is meshedly connected with the outer side of the driving rack plate, and one end of the driving shaft is movably connected to the inner wall of the mounting top plate through a bearing.

[0021] Working principle: To use this device, first place the aluminum oxide to be crushed on the top of the crushing frame, then start the drive motor to drive the second gear to rotate. Since the second gear and the first gear are meshed with each other, the rotation of the second gear will drive the first gear to rotate, thus driving the two crushing rollers to rotate towards each other, and the aluminum oxide is initially crushed;

[0022] The crushed alumina falls onto the outer surface of the arc filter through the feed hopper. At this time, the first synchronous wheel is driven by the drive motor to rotate, and the second synchronous wheel is driven to rotate synchronously under the transmission of the belt, further realizing the rotation of the first bevel gear. Since the first bevel gear and the second bevel gear are meshed with each other, the rotation of the first bevel gear drives the second bevel gear to rotate synchronously, and then drives the reciprocating screw to rotate synchronously, so that the thread block reciprocates left and right along the outer surface of the reciprocating screw, further realizing the synchronous movement of the connecting frame, thus driving the grinding roller to move along the slide groove inside the arc frame, and using the movement of the grinding roller to further refine the alumina;

[0023] The ground nano-alumina falls into the discharge plate through the filter holes inside the arc filter. At this time, the electric guide rail and the electric slider drive the discharge plate to move outward, thus realizing automatic unloading.

[0024] When the grinding roller moves, it will drive the movable cylinder and the fixed cylinder to move synchronously, thus driving the drive shaft to swing forward and backward, and further making the drive gear swing forward and backward. Since the drive gear and the drive rack plate are meshed with each other, when the drive gear swings forward and backward, it will drive the drive rack plate to move back and forth. At this time, it will drive the second connecting plate to move synchronously, and move the drive block along the inner wall of the movable groove. In this way, the swing frame can swing back and forth under the auxiliary rotation of the mounting seat, and the striking plate will repeatedly hit the rigid plate to make the rigid plate vibrate, and the vibration of the rigid plate will be transmitted to the arc filter, so that the nano-alumina blocked in the filter holes of the arc filter will be shaken out.

[0025] The present invention provides a grinding and processing device for high-purity nano-alumina, which has the following beneficial effects:

[0026] 1. The present invention can significantly improve the processing efficiency and product quality of alumina by adding a crushing component and a preliminary grinding component. The crushing component can initially crush the alumina particles and reduce the particle size, making it easier to handle when entering the subsequent grinding stage. Afterwards, through the cooperation of the arc filter and the grinding roller, a finer grinding is achieved to ensure the particle size uniformity and purity of the final product. Compared with the prior art, this design not only improves the continuity and stability of the grinding process, but also reduces energy consumption, increases output, and reduces the risk of particle aggregation and re-agglomeration, ultimately making the production of high-purity nano alumina more efficient, economical and environmentally friendly.

[0027] 2. The present invention can automatically discharge the prepared nano-alumina by adding a feeding component, thereby improving production efficiency, reducing manual intervention, ensuring the continuous flow of materials, and achieving higher production capacity. At the same time, it helps to reduce cross contamination and material loss, improve the purity of high-purity nano-alumina, and ensure that the final product meets strict quality standards.

[0028] 3. The present invention adds a knocking component to continuously vibrate and knock the arc filter, effectively preventing the clogging of the filter surface by the aluminum oxide powder, ensuring the smooth passage of the material, thereby improving the efficiency of grinding and separation. Secondly, continuous vibration and knocking can keep the filter clean, reduce the problem of filter clogging caused by particle accumulation, and thus reduce maintenance costs and downtime.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Please refer to the attached Figure 1 - Attachment Fig. 9 The embodiment of the present invention provides a grinding processing device for high-purity nano-alumina, comprising:

[0041] A grinding frame 1, which serves as a support carrier of the entire device, and a crushing assembly for crushing aluminum oxide is installed on one side of the top of the grinding frame 1;

[0042] The crushing assembly includes a crushing frame 201, which is fixedly connected to the left side of the grinding frame 1. Two crushing rollers 202 are rotatably connected inside the crushing frame 201. A driving motor 206 is installed on the outside of the crushing frame 201. The output end of the driving motor 206 is fixedly connected to a second gear 205. The outer side of the second gear 205 is meshed with a first gear 204. The second gear 205 is fixedly connected to one end of one of the crushing rollers 202, and the first gear 204 is fixedly connected to one end of the other crushing roller 202. The outer side of the crushing frame 201 is connected to a feed hopper 203.

[0043] A fine grinding assembly, which is mounted on the top of the grinding frame 1 and is used to further grind the crushed aluminum oxide;

[0044] The fine grinding assembly includes an arc filter 301, which is detachably connected to the top of the grinding frame 1. A reciprocating screw rod 309 is installed on the front side of the grinding frame 1. The reciprocating screw rod 309 is externally threadedly connected to a threaded block 308. The top of the threaded block 308 is fixedly connected to a connecting frame 307. A groove is provided inside the connecting frame 307. The front and rear sides of the top of the grinding frame 1 are fixedly connected to an arc frame 305. The inner side of the arc frame 305 is movably connected to a grinding roller 302. The front and rear ends of the grinding roller 302 are rotatably connected to a movable cylinder 304. The outer surface of the movable cylinder 304 is slidably connected to a fixed cylinder 303. The inner top wall of the fixed cylinder 303 is fixedly connected to a spring 306. The other end of the spring 306 is fixedly connected to a movable plate 310. The movable plate 310 is slidably connected to the inner wall of the fixed cylinder 303, and the bottom of the movable plate 310 is fixedly connected to the top of the movable cylinder 304.

[0045] Specifically, the filter can be detachably connected to the top of the grinding frame 1, and is designed to be arc-shaped to adapt to the overall structure of the grinding frame 1, ensuring that the refined aluminum oxide particles can be effectively filtered out during the grinding process to prevent particle clogging. The filter is made of wear-resistant and corrosion-resistant materials that can withstand high-intensity grinding operations. Connecting frame 307: A groove is provided inside, which is designed to accommodate and guide the moving trajectory of the grinding roller 302 to ensure that the movement of the grinding roller 302 is smoother. The surface of the grinding roller 302 has been specially treated and has excellent grinding performance, and can efficiently refine the aluminum oxide particles. The inner top wall of the fixed cylinder 303 is fixedly connected to a spring 306, and the other end of the spring 306 is fixedly connected to the movable plate 310 to ensure that the movable plate 310 can maintain appropriate pressure during the grinding process, thereby enhancing the grinding effect.

[0046] During the fine grinding process, the synchronous rotation of the reciprocating screw 309 causes the threaded block 308 to reciprocate left and right along its outer surface. This movement directly drives the synchronous movement of the connecting frame 307, which in turn drives the grinding roller 302 to slide in the slide groove inside the arc frame 305. The movement of the grinding roller 302 allows the aluminum oxide particles to be further refined. Due to the special design of the arc frame 305, the grinding roller 302 can apply pressure to the particles at an ideal angle, thereby enhancing the grinding effect. As the grinding roller 302 moves, the refined aluminum oxide particles are discharged through the arc filter 301, achieving the purpose of fine grinding.

[0047] The assembly can achieve efficient particle refinement by coordinating the movement of various components, and is easy to clean and maintain due to its modular design. At the same time, the fine grinding assembly can be adjusted as needed under different working conditions to ensure optimal performance in various grinding environments, greatly improving the production efficiency and product quality of high-purity nano alumina.

[0048] A feeding assembly, which is installed inside the grinding frame 1 and is used to automatically feed the aluminum oxide powder inside the grinding frame 1;

[0049] A first transmission assembly, which is mounted outside the crushing frame 201 and is used to drive the fine grinding assembly;

[0050] Please refer to the attached Figure 1 and attached Figure 5 The first transmission assembly includes a first synchronous wheel 501, which is fixedly connected to the output end of the driving motor 206. The outside of the first synchronous wheel 501 is connected to the second synchronous wheel 503 through a belt. The outside of the second synchronous wheel 503 is fixedly connected to the first bevel gear 502. The outer side of the first bevel gear 502 is meshedly connected to the second bevel gear 504. The outer side of the first bevel gear 502 is meshedly connected to the outer side of the second bevel gear 504.

[0051] Specifically, the first synchronous wheel 501 is driven to rotate by the driving motor 206, and the second synchronous wheel 503 is driven to rotate synchronously under the transmission effect of the belt, thereby further realizing the rotation of the first bevel gear 502. Since the first bevel gear 502 and the second bevel gear 504 are meshed with each other, the rotation of the first bevel gear 502 drives the second bevel gear 504 to rotate synchronously.

[0052] A knocking assembly, which is installed on the outside of the grinding frame 1 and is used to intermittently knock the outer surface of the grinding frame 1;

[0053] Please refer to the attached Figure 2 and attached Figure 4The knocking assembly includes a mounting seat 602, which is fixedly connected to the left side of the grinding frame 1. The inner side of the mounting seat 602 is connected to a swing frame 601 through a pin shaft. The inner side of the swing frame 601 is provided with a movable groove 605. The inner side of the movable groove 605 is slidably connected to a driving block 606. The outer side of the driving block 606 is rotatably connected to a second connecting plate 607. The bottom end of the swing frame 601 is fixedly connected to a striking plate 604. The outer surface of the grinding frame 1 is fixedly connected to a rigid plate 603. One end of the second connecting plate 607 away from the driving block 606 is fixedly connected to one end of the driving rack plate 402. The swing frame 601 is L-shaped.

[0054] Specifically, the inner side of the mounting seat 602 is connected to the swing frame 601 through a pin shaft to form a swingable connection. The swing frame 601 adopts an L-shaped design, so that it can effectively increase the striking range during the movement, thereby improving the striking effect on the rigid plate 603. The bottom end of the swing frame 601 is fixedly connected with a striking plate 604, which directly participates in the striking of the rigid plate 603 to generate vibration.

[0055] During the grinding process, the movement of the grinding roller 302 causes the synchronous movement of the movable cylinder 304 and the fixed cylinder 303, and this process further drives the driving shaft 401 to swing forward and backward. The swing of the driving shaft 401 causes the driving gear 403 to swing forward and backward, and the driving gear 403 and the driving rack plate 402 are meshed with each other, so that the driving rack plate 402 reciprocates. This movement directly affects the second connecting plate 607, causing it to move synchronously, driving the driving block 606 to move along the inner wall of the movable groove 605.

[0056] Under the auxiliary rotation of the mounting seat 602, the swing frame 601 realizes reciprocating swing. Each swing causes the striking plate 604 to repeatedly strike the rigid plate 603 fixedly connected to the outer surface of the grinding frame 1, generating a certain vibration force. The rigid plate 603 will vibrate while being struck, and this vibration is transmitted to the arc filter 301 through the rigid plate 603, thereby shaking out the nano-aluminum oxide particles blocked in the filter holes of the filter.

[0057] The design of the knocking component effectively solves the problem of filter blockage caused by particle aggregation during the grinding process, ensuring the fluidity of the material and the continuity of grinding. At the same time, by optimizing the frequency and intensity of the knocking, the impact effect on the filter can be accurately controlled, thereby improving the grinding efficiency and product quality. In addition, the structural design of this component is simple, easy to maintain and adjust, reducing the downtime in the production process, and providing strong technical support for the production of high-purity nano-alumina. Through this innovative design, the overall equipment has been significantly improved in terms of processing efficiency, product quality and economy.

[0058] The second transmission assembly is installed on the outside of the fine grinding assembly and is used to drive the knocking assembly.

[0059] Please refer to the attached Figure 2 , Attachment Figure 3 and attached Figure 4 The second transmission assembly includes a mounting top plate 406 and a driving shaft 401. The mounting top plate 406 is fixedly connected to the top of the grinding frame 1. Two support frames 405 are fixedly connected to the middle of the bottom end of the driving shaft 401. The bottom end of the support frame 405 is fixedly connected to the first connecting plate 404. The inside of the first connecting plate 404 is slidably connected to the driving rack plate 402. The driving shaft 401 is fixedly connected to the inner side of the fixed cylinder 303. The middle of the outer side of the driving shaft 401 is fixedly connected to the driving gear 403. The outer side of the driving gear 403 is meshed and connected with the outer side of the driving rack plate 402. One end of the driving shaft 401 is movably connected to the inner wall of the mounting top plate 406 through a bearing.

[0060] Specifically, the second transmission assembly of the present invention ensures the efficient operation of the high-purity nano-alumina grinding and processing equipment through the precise coordination of a series of mechanical structures. The top plate 406 is installed to provide a solid support foundation for the entire transmission assembly. The function of the support frame 405 is to enhance the stability of the drive shaft 401 and ensure its balance during operation. The bottom end of the support frame 405 is fixedly connected to the first connecting plate 404 to form a slidable connection interface to support the subsequent reciprocating motion of the drive rack plate 402.

[0061] When the driving shaft 401 rotates, the driving gear 403 also rotates accordingly. Due to the meshing relationship between the driving gear 403 and the driving rack plate 402 , the rotation of the driving gear 403 will directly lead to the reciprocating motion of the driving rack plate 402 .

[0062] The operating principle of the transmission system is that the drive shaft 401 is driven by the motor to swing forward and backward, which further causes the drive gear 403 to swing forward and backward. Due to the mutual meshing of the drive gear 403 and the drive rack plate 402, the swing of the drive gear 403 drives the drive rack plate 402 to move back and forth accurately. This reciprocating motion can effectively transmit power and generate the necessary vibration force during the grinding process to promote the interaction between particles, thereby improving the grinding efficiency and product quality.

[0063] Please refer to the attached Figure 8 and attached Fig. 9 The unloading assembly includes two electric guide rails 702 , an electric slider 703 is installed outside the electric guide rails 702 , a discharge plate 701 is slidably connected to the bottom of the grinding frame 1 , and the outsides of the two electric sliders 703 are fixedly connected to the outer sides of the discharge plate 701 .

[0064] Specifically, the design of the unloading component of the present invention is intended to achieve automation and efficiency in the high-purity nano-alumina grinding process. During the grinding process, the finely ground nano-alumina particles pass through the internal filter holes of the arc filter 301 and fall accurately onto the discharge plate 701. At this time, the cooperation between the electric guide rail 702 and the electric slider 703 plays a key role. Driven by the electric guide rail 702, the electric slider 703 can move smoothly along the guide rail, thereby driving the discharge plate 701 to move outward. This movement mechanism ensures that the nano-alumina particles can be discharged quickly and continuously from the grinding frame 1, realizing automatic unloading.

[0065] The automatic unloading system not only improves production efficiency and reduces manual intervention, but also greatly reduces the loss of materials during the unloading process. Through accurate movement and control, the unloading plate 701 can smoothly unload the materials within the specified time, thereby maintaining the continuity of the entire grinding process. In addition, the design of the electric slider 703 makes the movement of the unloading plate 701 more flexible and can be adjusted according to different production requirements to adapt to different material flow rates and particle characteristics.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
