Description

A boehmite cleaning device and its usage method Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a boehmite cleaning device and its usage method. Background Technology

[0002] Boehmite is composed of a partially filled aluminum cation-rich double-layered oxygen octahedral structure, characterized by high porosity, large specific surface area, good dispersibility, good colloidal properties, good heat resistance, and low hardness. It was first discovered by the German chemist Johann Boehm in 1925 and named after him. Boehmite has various industrial applications, including as a flame retardant and a coating material for lithium-ion battery cell separators and electrodes. As a flame retardant, boehmite decomposes above 400℃; as a lithium-ion battery material, it can increase the heat resistance and puncture resistance of the separator, improving the safety performance and energy density of lithium-ion batteries. Furthermore, boehmite exhibits excellent flame retardancy, processability, and leakage resistance, particularly excelling in improving the flame retardancy, leakage resistance, and heat resistance of copper-clad laminates.

[0003] In the boehmite production process, after centrifugation, the boehmite needs to be washed with anhydrous ethanol and dried to obtain the finished product. Because boehmite has an irregular shape and tends to stack, commonly used cleaning devices cannot completely clean its surface, easily increasing the defect rate. Therefore, it is necessary to provide a boehmite cleaning device and its usage method to solve the above problems. Based on the above problems existing in the prior art, the purpose of this application is to provide a boehmite cleaning device and its usage method to solve the problems mentioned in the background art.

[0044] As shown in Figure 6, the transmission assembly 4 includes a rotating device 401 and a transmission device 402. When the rotating device 401 rotates, it can transmit the generated force to the transmission device 402.

[0045] As shown in Figure 7, the rotating device 401 includes a first gear 4011, a connecting shaft 4012, a first positioning sleeve 4013, a second positioning sleeve 4014, and a rotating block 4015. The connecting shaft 4012 is engaged with the center of the first gear 4011. When the first gear 4011 rotates, it can drive the connecting shaft 4012 to rotate.

One end of the swing block 4022 has a connection hole 40221, which is fixedly connected to one of the connection posts 2012.

[0047] As shown in Figure 9, the drive assembly 5 includes a motor 51, which is electrically connected to the control center and fixedly connected to the third limiting member 2022. The output end of the motor 51 is fixedly connected to a second gear 52, and the motor 51 provides power for the rotation of the second gear 52.

[0048] Example 1: Steps for using this device

[0049] Step 1: Pour in anhydrous ethanol and install chain 6.

[0050] Specifically, as shown in Figure 10, open the cover 301, pour the boehmite to be cleaned into the filter screen 302, and then pour anhydrous ethanol into the filter screen 302. After the anhydrous ethanol covers the boehmite to a certain height, stop adding it and put the cover 301 on top of the filter screen 302.

[0051] Fit a suitable chain 6 onto the gear teeth 303, the first gear 4011, and the second gear 52. Adjust the tension of the chain 6 so that when the chain 6 rotates, it can drive the gear teeth 303, the first gear 4011, and the second gear 52 to rotate.

[0052] Step 2: Start motor 51, the device begins operation, and the boehmite is cleaned.

[0053] Specifically, the motor 51 is started by the control center. The motor 51 drives the second gear 52 to rotate, which in turn drives the chain 6 to rotate. The rotation of the chain 6 drives the filter screen 302 and the first gear 4011 to rotate.

[0054] When the filter screen 302 rotates, it drives the rotating shaft 304 to rotate with the filter screen 302. At this time, the first stirring rod 305 and the second stirring rod 306 stir the anhydrous ethanol at the bottom of the barrel 201, so that the anhydrous ethanol inside the barrel 201 flows.

[0055] When the first gear 4011 rotates, it drives the connecting shaft 4012 to rotate, causing the rotating block 4015 to rotate eccentrically. This drives the transmission connecting piece 4021 to move back and forth. When the connecting piece 4021 moves, it slides on the guide post 4023. At the same time, the guide post 4023 can drive the swing block 4022 to swing. When the swing block 4022 swings, the connecting post 2012, which is fixedly connected to the swing block 4022, rotates, causing the barrel body 201 to rotate. The barrel body 201 swings about the connecting post 2012 as an axis. As shown in Figure 11, the load-bearing wheel 204 swings with the swing of the barrel body 201. The load-bearing wheel 204 moves within the arc groove 1042, which can increase the stability of the barrel body 201 and prevent the connecting column 2012 from breaking when the barrel body 201 is shaken. As the barrel body 201 swings, the boehm stone in the filter screen 302 also shakes. At the same time, the rotation of the filter screen 302 allows the boehm stone to fully contact the anhydrous ethanol, so that all surfaces of the boehm stone can contact the anhydrous ethanol and be fully cleaned.

[0056] Due to the influence of gravity, when the barrel 201 swings, it can also drive the transmission component 4 to work in the opposite direction, causing the filter screen 302 to rotate. At this time, the speed of the motor 51 can be reduced by the control center, which can also maintain the operation of the entire device, thereby reducing the workload of the motor 51 and saving electricity costs.

[0057] Step 3: Open the cover 301 and observe the cleaning effect of the boehm stone.

[0058] Stop the operation of motor 51 through the control center, make the barrel 201 perpendicular to the ground, open the cover 301, lift the filter screen 302, shake the filter screen 302 slightly to drain the anhydrous ethanol, and at the same time observe whether the boehm stone is clean. After the boehm stone is clean, take out the boehm stone and proceed to the next process.

[0059] Example 2: In step three above, the boehmite may not be cleaned thoroughly. This device can adjust its cleaning method according to the actual cleaning needs of the boehmite.

[0060] Specifically, a chain 6 of appropriate length is selected and nested on the gear teeth 303 and the second gear 52. The motor 51 is started through the control center. At this time, the second gear 52 rotates, driving the gear teeth 303 to rotate. The filter screen 302 and the rotating shaft 304 rotate, causing the anhydrous ethanol in the barrel 201 to flow and impact the boehmite, thus achieving a cleaning effect. After the anhydrous ethanol in the barrel 201 is emptied, the motor 51 is started in the same way as described in this embodiment. At this time, the filter screen 302 rotates, which can accelerate the evaporation of anhydrous ethanol on the surface of the boehmite and save processing time in this step.

[0061] Select a chain 6 of appropriate length and nest it on the first gear 4011 and the second gear 52. Start the motor 51 through the control center. At this time, the second gear 52 rotates, driving the gear teeth 303 to rotate. Through the transmission component 4, the barrel 201 swings around the connecting column 2012. At this time, the anhydrous ethanol in the barrel 201 and the boehm stones in the filter screen 302 begin to sway left and right. The accumulated boehm stones roll with the swing of the barrel 201, increasing the contact area between the boehm stones and the anhydrous ethanol.

[0062] It should be noted that, without the drive component 5, the device can select a suitable chain 6 and install it on the first gear 4011 and the gear teeth 303. By pushing the barrel 201, the barrel 201 can be made to swing. At the same time, the filter screen 302 can be rotated through the transmission component 4, so that the device can still clean boehmite even without power.

[0063] By incorporating a transmission component 4, this device can uniformly adjust the rotation speed of the filter screen 302 and the barrel 201. Simultaneously, rotating the filter screen 302 and swinging the barrel 201 can displace the boehm stones, making it easier to clean their surfaces. Furthermore, the device can independently control the rotation of the filter screen 302 and the barrel 201, increasing its practicality. This solves the technical problem that the irregular shape of boehm stones, which tend to stack together, prevents commonly used cleaning devices from completely cleaning their surfaces, thus increasing the defect rate.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
