Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and specifically to a boehmite cleaning device and a method for using the same. Background Art

[0002] Boehmite is composed of a double-layer oxygen octahedral structure partially filled with aluminum cations. It has the characteristics of large porosity, large specific surface area, good dispersibility, good gel solubility, good heat resistance and low hardness. Boehmite was first discovered by German chemist Johann Boehm in 1925 and named after him. Boehmite has many industrial applications, including as a flame retardant, coating material for lithium battery cell separators and pole pieces, etc. As a flame retardant, boehmite decomposes above 400°C; as a lithium battery material, it can increase the heat resistance and puncture resistance of the separator, and improve the safety performance and energy density of lithium batteries. In addition, boehmite also has excellent flame retardancy, processability and leakage resistance, especially in improving the flame retardancy of copper clad laminates, leakage resistance of substrates and heat resistance.

[0003] In the boehmite production process, after centrifugal separation, it needs to be cleaned with anhydrous ethanol and dried to obtain the finished product. Since boehmite has an irregular shape and is easily stacked together, the commonly used cleaning device cannot completely clean the surface of the boehmite, which easily increases the defective rate.

[0050] like Figure 6 As shown, the transmission assembly 4 includes a rotating device 401 and a transmission device 402 . When the rotating device 401 rotates, the generated force can be transmitted to the transmission device 402 .

[0051] like Figure 7 As shown, 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.

One end of the guide column 4023 is fixedly connected to the swing block 4022, and the connecting member 4021 is slidably connected to the guide column 4023. A connecting hole 40221 is provided at one end of the swing block 4022, and the connecting hole 40221 is fixedly connected to one of the connecting columns 2012.

[0053] like Fig. 9 As shown, the driving assembly 5 includes a motor 51, which is electrically connected to the control center, fixedly connected to the third limiter 2022, and a second gear 52 is fixedly connected to the output end of the motor 51, and the motor 51 provides power for the rotation of the second gear 52.

[0054] Embodiment 1: Steps of using the device

[0055] Step 1: Pour in anhydrous ethanol and install the chain 6

[0056] Specifically, Fig.10As shown, open the cover 301, pour the boehmite to be cleaned into the filter 302, and then pour anhydrous ethanol from the filter 302. After the anhydrous ethanol covers the boehmite to a certain height, stop adding and cover the cover 301 on the top of the filter 302.

[0057] A suitable chain 6 is put on the gear teeth 303, the first gear 4011 and the second gear 52, and the tension of the chain 6 is adjusted so that the chain 6 can drive the gear teeth 303, the first gear 4011 and the second gear 52 to rotate when rotating.

[0058] Step 2: Start the motor 51, the device starts to run, and the boehmite is cleaned

[0059] Specifically, the motor 51 is started by the control center, the motor 51 drives the second gear 52 to rotate, thereby driving the chain 6 to rotate, and the rotation of the chain 6 drives the filter screen 302 and the first gear 4011 to rotate.

[0060] When the filter screen 302 rotates, the rotating shaft 304 is driven to rotate along 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 body 201 , so that the anhydrous ethanol inside the barrel body 201 flows.

[0061] When the first gear 4011 rotates, it drives the connecting shaft 4012 to rotate, so that the rotating block 4015 rotates eccentrically, driving the transmission connecting member 4021 to move forward and backward. When the connecting member 4021 moves, it slides on the guide column 4023. At the same time, the guide column 4023 can drive the swing block 4022 to swing. When the swing block 4022 swings, the connecting column 2012 fixedly connected to the swing block 4022 rotates, so that the barrel body 201 rotates, and the barrel body 201 swings around the connecting column 2012 as the axis. Fig.11 As shown, the load-bearing wheel 204 swings along with the swing of the barrel body 201. The load-bearing wheel 204 moves in 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 boehmite in the filter screen 302 also shakes. At the same time, the filter screen 302 rotates so that the boehmite can fully contact with the anhydrous ethanol, so that all sides of the boehmite can contact with the anhydrous ethanol and be fully cleaned.

[0062] Under the influence of gravity, when the barrel body 201 swings, it can also drive the transmission assembly 4 to work in the reverse direction, so that the filter 302 rotates. At this time, the speed of the motor 51 can be reduced through the control center, and the operation of the entire device can also be maintained, thereby reducing the working intensity of the motor 51 and saving electricity costs.

[0063] Step 3: Open the cover 301 and observe the cleaning effect of boehmite

[0064] The motor 51 is stopped by the control center, the barrel body 201 is made vertical to the ground, the cover 301 is opened, the filter screen 302 is lifted, and the filter screen 302 is slightly shaken to drain out the anhydrous ethanol. At the same time, it is observed whether the boehmite is cleaned. When the boehmite is cleaned, the boehmite is taken out for the next process.

[0065] Example 2: In the above step 3, the boehmite may not be cleaned thoroughly. The device can adjust the cleaning method of the device according to the actual cleaning requirements of the boehmite.

[0066] Specifically, a chain 6 of appropriate length is selected, and the chain 6 is nested on the gear 303 and the second gear 52, and the motor 51 is started through the control center. At this time, the second gear 52 rotates to drive the gear 303 to rotate, and the filter 302 and the rotating shaft 304 rotate, so that the anhydrous ethanol in the barrel body 201 flows, impacting the boehmite, thereby achieving a cleaning effect; after the anhydrous ethanol in the barrel body 201 is emptied, the motor 51 is started in the same manner as described above in this embodiment. At this time, the filter 302 rotates, which can accelerate the volatilization of the anhydrous ethanol on the surface of the boehmite, saving the processing time of this process.

[0067] Select a chain 6 of appropriate length, embed the chain 6 on the first gear 4011 and the second gear 52, start the motor 51 through the control center, and then the second gear 52 rotates to drive the gear 303 to rotate, and the barrel body 201 is driven by the transmission component 4 to swing around the connecting column 2012. At this time, the anhydrous ethanol in the barrel body 201 and the boehmite in the filter 302 begin to swing left and right, and the accumulated boehmite rolls with the swing of the barrel body 201, increasing the contact area between the boehmite and the anhydrous ethanol.

[0068] It should be noted that, in the absence of a driving component 5, the device selects a suitable chain 6, which is installed on the first gear 4011 and the gear 303, and pushes the barrel body 201 to make the barrel body 201 swing. At the same time, the filter screen 302 can also be rotated through the transmission component 4, so that the device can still clean the boehmite without power supply.

[0069] The device is provided with a transmission component 4, which can uniformly adjust the rotation speed of the filter 302 and the rotation speed of the barrel body 201. At the same time, the rotating filter 302 and the swinging barrel body 201 can cause the boehmite to be displaced, making it easier to clean the surface of the boehmite. At the same time, the device can also control the rotation of the filter 302 and the rotation of the barrel body 201 separately, thereby increasing the practicality of the device and solving the technical problem that the boehmite has an irregular shape and is easy to stack together, resulting in the inability of commonly used cleaning devices to completely clean the surface of the boehmite, which easily increases the defective rate.

[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
