Description

Technical Field

[0001] The invention relates to the technical field of graphene oxide, and in particular to a device for separating graphene oxide using a ceramic composite membrane. Background Art

[0002] Graphene oxide is the oxide of graphene, and its color is brownish yellow. Common products on the market are powder, flake and solution. Graphene oxide flakes are the product of graphite powder after chemical oxidation and exfoliation. Graphene oxide is a single atomic layer that can be expanded to tens of microns in lateral size at any time.

[0003] In the process of separating graphene oxide from the graphene mixture, the traditional separation device has a low separation efficiency and takes a long time to separate it.

[0004] For example, a device for separating graphene oxide with a ceramic composite membrane is provided in the authorization announcement number CN109289536B. When the device for separating graphene oxide with a ceramic composite membrane is used, a graphene mixture is manually put into the feed port, and then water is injected from the water inlet. The water pump is turned on and the water pump works to make water flow out of the water tank to form a water flow loop. The electric heating tube is turned on and heated by the electric heating tube. The heating time is manually controlled to increase the water temperature of the water flow loop. At this time, the motor is turned on and the motor rotates. The stirring rod stirs the graphene mixture to separate the graphene mixture from the graphene oxide, and then passes through the first filter screen, the ceramic composite membrane and the second filter screen. Graphene oxide can be obtained by filtration. The device for separating graphene oxide with the ceramic composite membrane has the advantages of simple structure, convenient operation, low cost, resource saving, small footprint, convenient transportation and storage. The graphene mixture is heated in a water bath to make the graphene easier to separate. The graphene mixture is stirred by a stirring rod to greatly increase the filtration area of ​​the graphene mixture, which is beneficial to the separation of graphene oxide. At the same time, the ceramic composite membrane is used for filtration and separation to avoid incomplete separation of graphene oxide and the need for multiple washings, which is beneficial to the separation of graphene oxide, better effect, greatly increased work efficiency and time saving.

[0005] It has major drawbacks: during use, the mixing efficiency achieved by the stirring rod alone is poor, and a large amount of graphene mixture will adhere to the surface of the second conduit after long-term use, which will cause the water bath heating efficiency of the second conduit to deteriorate. At the same time, when the graphene mixture is placed in the inverted separation barrel, the graphene mixture will be directly filtered from the first filter screen, the ceramic composite membrane and the second filter screen. Direct filtration may be affected by the particle size and distribution in the mixture. Larger particles or clumps may easily block the membrane pores and reduce the filtration efficiency. At the same time, some impurities in the part of the mixture that is not heated in the water bath may not be removed or converted, resulting in a decrease in the purity of graphene oxide. Summary of the invention

[0006] The embodiment of the present application provides a device for separating graphene oxide using a ceramic composite membrane, which solves the problem that the mixing efficiency achieved by a stirring rod alone in the prior art is poor. At the same time, a large amount of graphene mixture will adhere to the surface of the second conduit after long-term use, which will cause the water bath heating efficiency of the second conduit to deteriorate. At the same time, when the graphene mixture is placed in the inverted separation barrel, the graphene mixture will be directly filtered through the first filter screen, the ceramic composite membrane and the second filter screen. Direct filtration may be affected by the size and distribution of particles in the mixture. Larger particles or lumps may easily block the membrane pores and reduce the filtration efficiency. At the same time, some impurities in the part of the mixture that is not heated in the water bath It may not be able to be removed or converted, resulting in a decrease in the purity of graphene oxide. The water bath tube is transformed into an elastic spiral shape. During the use of the device, the lifting plate on the lower side of the water bath tube can be pulled by a traction rope to make the water bath tube continuously shrink and reset, which can increase the range of water bath heating and stir the graphene mixture to improve its separation efficiency. After the pulling of the traction rope disappears, the vibration generated by the reset of the water bath tube can shake off the graphene mixture attached to the surface of the water bath tube to prevent it from affecting the water bath heating effect. At the same time, by setting a discharge pipe and a valve on its surface, the internal graphene mixture can be completely heated to improve the purity of graphene oxide.

[0130] The bearing 410 is provided with gear teeth, the gear teeth are evenly distributed in a ring shape, and the power gear 430 is meshed with the gear teeth;

[0131] When the electromagnet 450 is energized, it attracts the magnetic sleeve 350 to change the position of the deformation block 312 .

[0132] During use, the power gear 430 driven by the second motor 420 can be rotated to adjust the position of the bracket 440 and the electromagnet 450, so that they are located on one side of the deformation block 312. By energizing the electromagnet 450, the magnetic suction sleeve 350 is adsorbed, so that the positions of multiple deformation blocks 312 on one side are changed, and a larger range of graphene mixture is heated. At the same time, after the electromagnet 450 is powered off, the deformation block 312 is reset through the rubber connected to the fixed block 311. The vibration generated during the reset process can shake off the deformation block 312 and the graphene mixture attached to the surface of the fixed block 311; after the deformation block 312 on one side is cleaned, the power gear 430 driven by the second motor 420 is rotated to adjust the position of the bracket 440 and the electromagnet 450, so that they are located on the other side, and multiple deformation blocks 312 on the other side can be adsorbed; and the work is performed reciprocatingly.

[0133] Through the adsorption of the electromagnet 450, the position of the deformation block 312 can be adjusted, and water bath heating can be performed for a larger range to improve the water bath heating efficiency. After the magnetic attraction disappears, the rubber is reset. During the rebound process, the vibration generated can shake off the graphene mixture attached to the surface of the deformation block 312 and the fixed block 311, thereby improving the cleaning effect.

[0134] Embodiment 3: When the second embodiment is in use, the graphene mixture attached to the surface of the vibrator is shaken off by the automatic reset of the deformation block 312 by the electromagnet 450 after power failure. However, when in use, the vibration generated by the reset of the deformation block 312 alone has a poor cleaning efficiency. Based on this, the solution of the second embodiment is improved, such as Figure 6-Figure 7 As shown:

[0135] The water bath assembly 300 also includes a limit group;

[0136] The number of the limit groups is consistent with the sum of the numbers of the deformation blocks 312 in the plurality of deformation groups, and they correspond one to one;

[0137] One of the limit groups includes two limit blocks 360 and two reset ropes 370, and the two limit blocks 360 correspond to the two reset ropes 370 one by one;

[0138] The limiting block 360 is annular, and the two limiting blocks 360 are respectively sleeved and fixed on the two ends of the deformation block 312;

[0139] One end of the reset rope 370 is fixed on the limit block 360 , and the other end of the reset rope 370 away from the limit block 360 is fixed on the magnetic suction sleeve 350 ;

[0140] The magnetic suction sleeve 350 is annular, and the inner ring of the magnetic suction sleeve 350 is adapted to the outer ring of the deformation block 312;

[0141] The inner diameter of the magnetic sleeve 350 is larger than the cross-sectional diameter of the deformation block 312 , the cross-sectional shape of the outer ring of the limit block 360 is circular, and the outer diameter of the limit block 360 is larger than the inner diameter of the magnetic sleeve 350 ;

[0142] The magnetic suction sleeve 350 is slidably disposed on the deformation block 312, and the inner ring of the magnetic suction sleeve 350 has a rubber layer, and the rubber layer of the inner ring of the magnetic suction sleeve 350 is tightly fitted on the outer ring of the deformation block 312;

[0143] The deformation block 312 is provided with a slideway, the inner ring of the magnetic suction sleeve 350 is provided with a slider, and the slider of the inner ring of the magnetic suction sleeve 350 is slidably arranged in the slideway of the deformation block 312;

[0144] The reset cord 370 is an elastic cord.

[0145] The power gear 430 driven by the second motor 420 rotates, and the positions of the bracket 440 and the electromagnet 450 are adjusted so that they are located outside the separation tank 110 and closest to the magnetic suction sleeve 350. When the magnetic suction sleeve 350 is attracted by the electromagnet 450, the power gear 430 driven by the second motor 420 rotates, so that the adjustment bracket 440 rotates 90 degrees clockwise and then resets, and then rotates 90 degrees counterclockwise, so that the surfaces of the multiple deformation blocks 312 on one side are completely cleaned. After the electromagnet 450 is powered off, the deformation block 312 is reset through the rubber connected to the fixed block 311. The vibration generated during the reset process can shake off the graphene mixture attached to the surface of the deformation block 312 and the fixed block 311, and the magnetic suction sleeve 350 can be reset by pulling the reset rope 370. After the cleaning of the multiple deformation blocks 312 on one side is completed, the adjustment bracket 440 rotates to the other side, and the same steps are used to clean the multiple deformation blocks 312 on the other side; the work is performed reciprocatingly.

[0146] By continuously adjusting the position of the electromagnet 450, the magnetic sleeve 350 can slide in the slideway on the deformation block 312. During the sliding process, the graphene mixture on the surface of the deformation block 312 can be continuously moved and scraped off, further improving the cleaning effect. At the same time, the magnetic sleeve 350 can be reset by the reset rope 370 for multiple cleanings.

[0147] Embodiment 4: When the embodiment 3 is in use, the graphene mixture attached to the surface of the deformation block 312 is cleaned by sliding the magnetic suction sleeve 350 on the deformation block 312. A large amount of graphene mixture will be attached to the front of the movement of the magnetic suction sleeve 350. Long-term accumulation will reduce the cleaning efficiency of the deformation block 312. Based on this, the solution of the embodiment 3 is improved, such as Figure 6-Figure 7 As shown:

[0148] The slideway on the deformation block 312 is spirally arranged on the outer circle.

[0149] When the magnetic sleeve 350 moves on the deformation block 312, since the slideway on the deformation block 312 is a spiral slideway, the magnetic sleeve 350 can rotate and move forward in a spiral shape. During the rotation and scraping process, the graphene mixture on the surfaces of the magnetic sleeve 350 and the deformation block 312 can be quickly thrown off by centrifugal force. In addition, when the magnetic sleeve 350 is reset by the reset rope 370, the centrifugal force generated by the rotation can also better throw off the graphene mixture attached to the surfaces of the magnetic sleeve 350 and the deformation block 312.

[0150] The magnetic sleeve 350 is rotated and advanced in a spiral shape on the spiral slideway on the surface of the deformation block 312. During the rotation, the centrifugal force generated can remove the graphene mixture attached to the surface of the magnetic sleeve 350 and the deformation block 312, which can further improve the cleaning effect.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
