Description

A graphene water washing device Technical Field

[0001] This utility model relates to the field of graphene technology, and in particular to a graphene water washing device. Background Technology

[0002] Graphene, a two-dimensional carbon nanomaterial composed of carbon atoms arranged in a hexagonal honeycomb lattice with sp² hybrid orbitals, has shown great application potential in fields such as electronic devices, energy storage, and composite materials due to its excellent electrical, thermal, and mechanical properties.

[0003] In the preparation and processing of graphene, the water washing process is the key step to remove impurities and improve product purity. High-quality water washing can not only effectively remove impurities such as catalyst residues and unreacted raw materials attached to the surface of graphene, but also improve its surface properties and enhance the overall performance of the material. With the rapid development of the graphene industry, the requirements for the efficiency, cleanliness and automation of water washing equipment are increasing. Developing more efficient and precise water washing equipment has become an important direction for technological breakthroughs in the industry.

[0004] Existing graphene washing devices employ either a simple agitation or spraying method. Agitation-type washing devices use mechanical agitation to ensure full contact between graphene and the cleaning solution, utilizing liquid flow to flush away impurities. Spraying-type washing uses nozzles to spray cleaning solution onto the graphene for cleaning. While these methods can avoid impurity residue to some extent and achieve initial cleaning of graphene, agitation-type washing relies solely on the water flow generated by mechanical agitation, making it difficult to effectively separate tiny particles of impurities. Furthermore, the agitation process can damage graphene sheets, affecting material properties. Spraying-type washing, due to its unidirectional and forceful water flow, is ineffective at cleaning tightly adhered impurities. The short contact time between the cleaning solution and graphene fails to fully dissolve and remove impurities. Additionally, the wastewater is directly discharged after washing, resulting in water waste and failing to meet the purity and quality requirements of graphene in high-end applications.

[0023] 1. In this utility model, the vibrating screen inside the slide cylinder driven by the vibrating motor performs graded filtration of the raw materials. The wastewater after washing enters the sedimentation mechanism, where large particles of impurities are separated by gravity and cyclone separation. The separated wastewater is then further processed by the centrifugal separation mechanism. The liquid is returned to the washing tank after being filtered through the return pipe and the filtration mechanism. This achieves the effects of efficient cleaning, impurity separation, and recycling of the cleaning liquid. Graded filtration effectively removes impurities from graphene, improving product purity.

Centrifugal force and the conical tank body separate small particles and substances with different densities. Impurities settle into the storage chamber, and the liquid is returned through a return pipe and a filtration mechanism. This achieves multi-stage separation of wastewater and recycling of the cleaning solution. Sedimentation and centrifugal separation effectively remove impurities of different particle sizes, ensuring the purity of the cleaning solution. Recycling the cleaning solution reduces costs, improves resource utilization, provides a good environment for graphene cleaning, and enhances product quality. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Referring to Figures 1, 2, and 3, an embodiment of this utility model is provided: a graphene washing device, including a processing table 1, a cleaning mechanism 2 is provided on the top left side of the processing table 1, the cleaning mechanism 2 is used to remove impurities in the graphene in stages, a sedimentation mechanism 3 is provided on the top of the processing table 1, a centrifugal separation mechanism 4 is provided on the top right side of the processing table 1, the cleaning mechanism 2 and the centrifugal separation mechanism 4 are connected through a return pipe 5, a filter mechanism 6 is provided in the middle of the return pipe 5, the filter mechanism 6 is used to filter the liquid that flows back into the cleaning mechanism 2 from the return pipe 5;

[0034] The cleaning mechanism 2 includes a cleaning tank 201, which is fixedly connected to the top left side of the processing table 1. A travel groove 202 is provided on the inner side of the cleaning tank 201. A slide cylinder 203 is slidably connected inside the travel groove 202. Multiple lifting rings 204 are fixedly connected at equal distances to the upper and lower sides of the slide cylinder 203 and the upper and lower walls of the travel groove 202. Springs 205 are engaged between the multiple lifting rings 204. Multiple vibrating screens 206 are fixedly connected inside the slide cylinder 203. Vibrating motors 207 are fixedly connected to the front and rear sides of the bottom of the cleaning tank 201. A feeding assembly is provided on the top of the cleaning tank 201. The feeding assembly includes a top plate 208. Multiple fixing bolts 209 are equidistantly passed through the top of the top of the top plate 208. A feeding cylinder 210 is connected to the top left side of the top of the top plate 208. A sealing cover plate 211 is rotatably connected to the top right side of the feeding cylinder 210. A handle 212 is fixedly connected to the top left side of the sealing cover plate 211.

[0035] Specifically, the graphene raw material to be cleaned enters the cleaning mechanism 2 through the feeding assembly. The cleaning tank 201 is fixedly connected to the top left side of the processing table 1. The graphene raw material to be cleaned enters the cleaning tank 201 through the feeding assembly, which includes a top plate 208 connected to the top of the cleaning tank 201 by multiple fixing bolts 209. The sealing cover 211, which is rotatably connected to the top right side of the top plate 208, can be opened through the handle 212 to pour the graphene raw material from the feeding cylinder 210 into the cleaning tank 201. A travel groove 202 is provided inside the cleaning tank 201, and the travel groove 202 slides inside. Next, the sliding cylinder 203 has multiple lifting rings 204 fixedly connected at equal intervals to the upper and lower sides of the sliding cylinder 203 and the upper and lower walls of the travel groove 202. Springs 205 engage with each of the lifting rings 204. When the vibration motor 207 at the bottom front and rear sides of the washing tub 201 is started, the generated vibration is transmitted to the sliding cylinder 203. The springs 205 buffer and assist the vibration, allowing the sliding cylinder 203 to slide stably within the travel groove 202. Multiple vibrating screens 206 are fixedly connected inside the sliding cylinder 203, and the multiple vibrating screens 206 adopt a filter hole design from large to small from top to bottom. Under the action of 07, the vibrating screen 206 vibrates accordingly, and the graphene raw material continuously tumbles and moves on the vibrating screen 206. Larger particles of impurities are first intercepted by the upper vibrating screen 206 and cannot pass through the screen holes. As the vibration continues, smaller particles of impurities gradually pass through the upper screen holes and reach the lower vibrating screen 206. The lower vibrating screen 206 further filters these smaller particles of impurities with smaller filter holes, thereby achieving graded filtration of impurities in the graphene. After cleaning, the wastewater and initially separated impurities in the cleaning tank 201 flow out from the bottom and enter the subsequent sedimentation. The wastewater in the sedimentation tank 301 is further processed. Under the action of gravity and swirling flow, large solid impurities in the wastewater settle to the bottom of the tank, achieving initial solid-liquid separation. The separated wastewater is pumped by the water pump 304 to the tank 401 of the centrifugal separation mechanism 4 to further separate small suspended particles and substances with different densities. The liquid after centrifugal separation flows back to the cleaning mechanism 2 through the return pipe 5. The filter mechanism 6 in the middle of the return pipe 5 filters the liquid, purifies the returned liquid, removes residual impurities, and the filtered clean liquid flows back into the cleaning tank 201, realizing the recycling of the cleaning liquid.

[0036] Referring to Figures 1, 2 and 4, the sedimentation mechanism 3 includes a sedimentation tank 301, which is fixedly connected to the top center of the processing table 1. A water pump 302 is fixedly connected to the left side of the sedimentation tank 301, and the input end of the water pump 302 is connected to the bottom center of the cleaning tank 201. Multiple threaded guide plates 303 are fixedly connected at equal intervals to the inner side of the sedimentation tank 301, and a water pump 304 is fixedly connected to the top of the sedimentation tank 301.

[0037] Specifically, the sedimentation tank 301 is fixedly connected to the top center of the processing table 1. Wastewater and impurities that have undergone preliminary cleaning in the cleaning mechanism 2 are transported to the sedimentation tank 301 via the suction pump 302. The suction pump 302 is fixed to the left side of the sedimentation tank 301, and its input end is connected to the bottom center of the cleaning tank 201. When the suction pump 302 starts, it generates suction to draw out the wastewater and impurities from the cleaning tank 201 and transport them to the sedimentation tank 301. As the wastewater and impurities flow within the sedimentation tank 301, the threaded guide plate 303 guides them to form a swirling flow. Under the action of this swirling flow, large solid particles in the wastewater are subjected to the combined effects of centrifugal force and gravity. Due to the higher density of these large solid particles, under the dual influence of centrifugal force and gravity, they gradually move towards the sedimentation tank 301. As time progresses, large solid particles accumulate at the bottom of the sedimentation tank 301, while the relatively clear wastewater, after initial separation, is located at the top of the sedimentation tank 301. At this point, the water pump 304, which is fixedly connected to the top of the sedimentation tank 301, starts to work. The water pump 304 extracts the relatively clear wastewater from the upper layer of the sedimentation tank 301 and transports it to the subsequent centrifugal separation mechanism 4 for further processing. The sedimentation mechanism 3 introduces the wastewater and impurities from the cleaning mechanism 2 into the sedimentation tank 301 through the suction pump 302. The spiral flow is formed by the threaded guide plate 303, causing the large solid particles to settle under the action of gravity and centrifugal force. Then, the water pump 304 transports the relatively clear wastewater from the upper layer to the next stage, thus achieving the initial separation of particulate solid impurities in the wastewater.

[0038] Referring to Figures 1 and 2, the centrifugal separation mechanism 4 includes a tank 401, which is fixedly connected to the top right side of the processing table 1. The input end of the return pipe 5 is connected to the right side of the tank 401, and the output end of the return pipe 5 is connected to the top front side of the cleaning tank 201. The output end of the water pump 304 is connected to the left side of the tank 401. A conical tank body 402 is fixedly connected to the bottom of the tank 401. A storage chamber 403 is provided at the bottom of the conical tank body 402. The storage chamber 403 is fixedly connected to the conical tank body 402 through a connecting assembly. The connecting assembly includes two flanges 404, which are fixedly connected to the bottom end of the conical tank body 402 and the top end of the storage chamber 403, respectively. Multiple fastening bolts 405 are equidistantly inserted through the outer sides of the two flanges 404.

[0039] Specifically, the wastewater, after preliminary treatment by the sedimentation unit 3, is pumped out from the top of the sedimentation tank 301 by the water pump 304 and transported through a pipeline to the tank 401 of the centrifugal separation unit 4. The tank 401 is fixedly connected to the right side of the top of the processing table 1. The tank 401 serves as the main container for centrifugal separation. After the wastewater enters the tank 401, centrifugal force is used to separate the tiny suspended particles and substances with different densities in the liquid. The conical tank body 402, fixedly connected to the bottom of the tank 401, plays a key role in the separation process. When centrifugal force is generated inside the tank 401, the liquid and the substances in it move towards the wall of the tank 401 under the action of centrifugal force. Because the tiny suspended particles and substances with higher density are subjected to greater centrifugal force, they gradually move towards the conical tank body 402 at the bottom of the tank 401. As the centrifugal action continues, these substances continuously accumulate in the conical tank body 402 and eventually settle to the bottom. The storage chamber 403 at the bottom of the conical tank body 402 is used to collect the separated impurities. The storage chamber 403 is connected to the conical tank body 402 by a connecting component. The conical tank body 402 is fixedly connected, and two flanges 404 in the connecting assembly are respectively fixed to the bottom end of the conical tank body 402 and the top end of the storage chamber 403. Multiple fastening bolts 405 pass through the outside of the flanges 404 to tightly connect the two, ensuring the sealing and stability of the connection. When the impurities in the storage chamber 403 accumulate to a certain amount, the flanges 404 can be separated by removing the fastening bolts 405, and the storage chamber 403 can be removed for cleaning. The relatively clean liquid after centrifugal separation flows back to the cleaning tank 201 of the cleaning mechanism 2 through the return pipe 5. The input end of the return pipe 5 is connected to the right side of the tank body 401, and the output end is connected to the top front side of the cleaning tank 201. During the return process, the liquid is filtered again by the filter mechanism 6 in the middle of the return pipe 5 to remove residual small impurities, ensuring that the liquid returning to the cleaning tank 201 meets the cleanliness standard, realizing the recycling of the cleaning liquid, and efficiently completing the separation of small suspended particles and substances with density differences in the liquid, providing a purer cleaning environment for graphene cleaning.

[0040] Referring to Figures 1, 2, and 5, the filter mechanism 6 includes two flange joints 601, both of which are fixedly connected to the right side of the middle of the return pipe 5. Two sealing shells 602 are engaged between the two flange joints 601. Multiple grids 603 are fixedly connected at equal intervals inside the two sealing shells 602. Filter elements 604 are placed between the multiple grids 603. Fixing feet 605 are fixedly connected to the front, rear, left, and right ends of the two sealing shells 602. Sealing bolts 606 penetrate the top of the multiple fixing feet 605 at the top. Sealing strips 607 are fixedly connected to adjacent sides of the two sealing shells 602. The ends of the multiple sealing bolts 606 are threaded into the interior of the multiple fixing feet 605 at the bottom.

[0041] Specifically, the filter mechanism 6 is installed on the right side of the middle of the return pipe 5, and is firmly connected to the return pipe 5 by two flange joints 601, providing basic support for the overall structure. Two sealing shells 602 are engaged between the flange joints 601, forming a relatively closed filtration space. Sealing bolts 606 penetrate the top of multiple fixing feet 605 at the top, and the ends of these sealing bolts 606 are threaded into the interior of multiple fixing feet 605 at the bottom, tightly fixing the two sealing shells 602 together. At the same time, the sealing strips 607 on the adjacent sides of the two sealing shells 602 ensure the sealing of the connection, preventing liquid leakage during the filtration process. When the filter element 604 needs to be replaced, the operator only needs to unscrew the sealing bolts 606 to easily separate the two sealing shells 602. At this time, the filter element 604, which was originally placed between multiple grids 603 inside the sealing shell 602, is exposed and can be directly removed. Because the filter element 604 is independently placed between the grids 603, the replacement process is very convenient. Depending on the filtration requirements, filter element 604 can be replaced with different types. When the return liquid mainly contains particulate impurities, filter element 604 with high-efficiency interception function can be selected. If the liquid contains a lot of dissolved pollutants, filter element 604 with adsorption function can be replaced. For some special pollutants, filter element 604 with catalytic decomposition function can also be selected. After replacing with the appropriate filter element 604, it is placed back between the grids 603, and then the two sealing shells 602 are re-fixed with fixing feet 605 and sealing bolts 606, while ensuring the sealing effect of sealing strip 607. The entire replacement process is completed, realizing the effect of flexible replacement and functional adaptation of filter element 604. The type of filter element 604 can be replaced at any time according to different water quality and impurity conditions, greatly improving the targeting and effect of filtration. At the same time, the modular disassembly design makes the process of replacing filter element 604 simple and easy, reducing the difficulty and cost of maintenance, and enhancing the versatility and practicality of the filtration mechanism 6.

[0042] Referring to Figures 1 and 2, a flow regulating valve 7 is fixedly installed on the left side of the middle part of the return pipe 5. The front side of the flow regulating valve 7 adopts an anti-slip design. A control console 8 is fixedly connected to the top front side of the processing table 1. The control console 8 is electrically connected to the vibration motor 207, the suction pump 302 and the pump 304.

[0043] Specifically, the flow regulating valve 7 on the left side of the middle of the return pipe 5 is used to control the flow rate and volume of liquid in the return pipe 5. Its front anti-slip design makes it easy for operators to manually rotate and adjust. By changing the valve opening, the flow rate of liquid returning from the centrifugal separation mechanism 4 to the cleaning mechanism 2 can be precisely controlled to meet the needs of different cleaning stages for the amount of cleaning liquid. The control console 8 on the front of the top of the processing table 1 serves as a control unit and is electrically connected to the vibration motor 207, the suction pump 302, and the pump 304. Through the operation interface of the control console 8, the vibration frequency of the vibration motor 207 can be set, the cleaning intensity of the cleaning mechanism 2 can be adjusted, and the start, stop, and power of the suction pump 302 and the pump 304 can be controlled to achieve stable transportation of sewage from the cleaning tank 201 to the sedimentation tank 301 and from the sedimentation tank 301 to the centrifugal separation mechanism 4.

[0044] Working principle: The graphene raw material to be cleaned enters the cleaning mechanism 2 through the feeding assembly. During feeding, the sealing cover 211 is opened by the handle 212, and the raw material is poured from the feeding cylinder 210 into the cleaning tank 201. The vibration motor 207 at the bottom of the cleaning tank 201 is started, and its vibration is transmitted to the slide cylinder 203 through the spring 205, causing the multi-layer vibrating screen 206 inside the slide cylinder 203 to vibrate. Since the filter holes of the vibrating screen 206 gradually decrease from top to bottom, it can classify and filter impurities in the graphene. Large particles of impurities are first intercepted by the upper screen, and small particles of impurities continue to be screened downwards. The cleaned wastewater and impurities are drawn out from the bottom of the cleaning tank 201 by the suction pump 302 and transported to the sedimentation tank 301 of the sedimentation mechanism 3. The threaded guide plate 303 inside the sedimentation tank 301 guides the wastewater to form a swirling flow, which is then spun by gravity and centrifugal force. Under the action of centrifugal force, large solid impurities settle to the bottom of the sedimentation tank 301. The wastewater after sedimentation is pumped by the water pump 304 to the tank 401 of the centrifugal separation mechanism 4. The centrifugal force in the tank 401 causes small suspended particles and substances with different densities to move towards the conical tank 402 and settle. Finally, the impurities are collected in the storage chamber 403. The storage chamber 403 is connected to the conical tank 402 by the flange 404 and fastening bolts 405 to facilitate the cleaning of impurities. The relatively clean liquid after centrifugal separation flows back to the washing tank 201 through the return pipe 5. During the return process, the liquid first passes through the filtration mechanism 6. In the filtration mechanism 6, two sealing shells 602 are fixed by the fixing feet 605 and the sealing bolts 606. The internal grid 603 supports the filter element 604. The filter element 604 filters the liquid again to remove residual impurities.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
