Description

Technical Field

[0001] The invention relates to the technical field of graphene preparation, in particular to graphene powder production equipment. Background Art

[0002] Graphene is a sp 2 A new material in which hybrid connected carbon atoms are tightly stacked into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. Common methods for producing graphene powders include mechanical exfoliation, redox, and membrane production. After the powder is produced, it needs to be ground because the powder particles are of different sizes and uneven coarseness.

[0003] When the existing device grinds graphene, an airflow is generated when the upper grinding plate rotates to grind the graphene. The generated airflow easily causes graphene powder to fly and adhere to the inner surface of the grinding chamber, resulting in waste of graphene and reduced production efficiency.

[0004] To this end, a graphene powder production device is proposed. Summary of the invention

[0005] The object of the present invention is to provide a graphene powder production device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a graphene powder production device, comprising a first tank body, the lower surface of the first tank body is open, and the lower surface of the first tank body is fixedly connected with a second tank body, the lower surface of the second tank body is fixedly installed with support legs distributed in a circular array, and a grinding mechanism capable of grinding graphene is arranged inside the first tank body.

[0007] When working, the existing device is easy to generate airflow when in use, which makes graphene powder fly, causing waste of graphene and reducing production efficiency. The present invention can ensure that the graphene is in a closed state when grinding by setting the first tank body, the second tank body and the grinding mechanism, thereby reducing the waste of graphene powder and improving production efficiency.

[0008] Preferably, the grinding mechanism includes a first grinding disc, a second grinding disc, a hydraulic rod, a connecting column, a motor, a vertical cylinder, a connecting pipe, a feed port, a discharge port, a baffle, an elastic sheet and a rotating column, the first tank body is fixedly connected to the inside of the first grinding disc, the first tank body is slidably mounted with a second grinding disc below the first grinding disc, and a truncated cone-shaped protrusion is provided in the middle position of the upper surfaces of the first grinding disc and the second grinding disc, a hydraulic rod is fixedly connected to the middle position of the lower surface of the second grinding disc, the lower surface of the hydraulic rod is fixedly connected to the connecting column, the connecting column is rotatably embedded in the middle position of the lower surface of the second tank body, and the connecting column passes through the lower surface of the second tank body and is fixedly connected to the motor, and a discharge port is fixedly installed on the right side of the lower surface of the second tank body The diameter of the second tank body is larger than that of the first tank body, a vertical cylinder is fixedly connected through the middle position of the truncated cone-shaped protrusion on the upper surface of the first grinding disk, the upper surface of the vertical cylinder is fixedly connected to the upper surface of the first tank body, a connecting tube is fixedly connected to the left side of the outer surface of the vertical cylinder, the upper end of the connecting tube passes through the upper surface of the first tank body and is fixedly connected to a feed port, a rotating column is rotatably connected to the inner surface of the connecting tube, a baffle is fixedly connected to the outer surface of the rotating column, and the outer surface of the baffle is adapted to the inner surface of the connecting tube, an elastic sheet is fixedly connected to the right side of the outer surface of the baffle near the rotating column, and the side of the elastic sheet away from the baffle is fixedly connected to the inner surface of the connecting tube, and a breaking mechanism is arranged on the left side of the upper surface of the first grinding disk.

[0009] During operation, after the production of graphene powder is completed, due to the different sizes and uneven coarseness of the powder particles, it needs to be ground. When the present invention is used, first, the graphene powder of uneven coarseness is poured into the first tank body through the feed port. Since a baffle, an elastic sheet and a rotating column are arranged inside the connecting tube, when the graphene powder passes through the connecting tube, the graphene powder will push the baffle to move to the right, so that the connecting tube is connected to the vertical cylinder, and the elastic sheet is in a compressed state at this time. The graphene powder falls onto the upper surface of the second grinding disc through the connecting tube and the vertical cylinder. Since the middle position of the upper surface of the second grinding disc is a truncated cone-shaped protrusion, the graphene powder can fall onto the edge of the upper surface of the second grinding disc through the truncated cone slope, and the hydraulic rod is driven to move up and down, which can drive the second grinding disc fixedly connected to the hydraulic rod to move up and down. The motor is moved so as to adjust the distance between the first grinding disc and the second grinding disc to control the diameter size of the powder particles, and then the motor is connected to the external power supply and driven to rotate, so as to drive the hydraulic rod and the second grinding disc to rotate, so as to grind the graphene. After grinding, the hydraulic rod is driven to move downward so that the second grinding disc moves downward into the second tank body. Since the diameter of the second tank body is larger than that of the first tank body, when the second grinding disc moves downward into the second tank body, the graphene powder on the second grinding disc can slide into the second tank body and then be discharged from the discharge port. The present invention provides a connecting pipe, a vertical cylinder, a baffle, etc., so that the space for feeding and grinding graphene is closed, so as to prevent the flying of graphene powder during grinding, thereby causing waste of graphene and improving production efficiency.

[0010] Preferably, a hemisphere is fixedly connected to the upper surface of the truncated cone-shaped protrusion on the upper surface of the second grinding disc.

[0011] During operation, when the graphene powder is transported through the vertical cylinder into the upper surface of the second grinding disk, since the frustum on the upper surface of the second grinding disk is horizontal, the graphene powder will stay on the upper surface of the frustum and cannot be ground. By fixing the hemisphere connected to the upper surface of the frustum-shaped protrusion on the upper surface of the second grinding disk, the graphene powder can slide along the hemisphere, avoiding the graphene powder from staying on the upper surface of the frustum, thereby ensuring that the graphene powder can be ground.

[0012] Preferably, a scraper is fixedly connected to the outer surface of the hemisphere, and the outer surface of the scraper is rotationally matched with the inner surface of the vertical cylinder, and an extension mechanism is fixedly installed on the upper surface of the scraper.

[0013] During operation, when the graphene powder is being transported, the graphene powder adheres to the inner surface of the vertical cylinder, causing waste. By setting a scraper, when the second grinding disc rotates, the scraper fixedly connected to the second grinding disc through the hemisphere rotates accordingly, so that the scraper can rotate relative to the vertical cylinder, and the graphene powder on the inner surface of the vertical cylinder can be scraped off, thereby avoiding the waste of graphene powder.

[0014] Preferably, the extension mechanism includes an extension plate, an annular slide and a circular plate. The connection between the upper surface of the vertical cylinder and the first tank body is open. The upper surface of the first tank body is coaxially fixedly connected with an annular slide and the vertical cylinder. A circular plate is rotatably embedded on the outer surface of the annular slide. The upper surface of the scraper is fixedly connected with an extension plate, and the side of the extension plate close to the inner surface of the vertical cylinder is rotatably matched with the vertical cylinder. The upper end of the extension plate passes through the circular plate and slidably matches with it.

[0015] During operation, when the second grinding disc moves downward, the scraper also moves downward, making it impossible to scrape the top of the vertical cylinder. By setting an extension mechanism, when the scraper moves downward, the extension plate connected to the scraper also moves downward. By setting a circular plate, the top of the vertical cylinder can be closed. Because the circular plate is connected to the first tank body through an annular slide plate, the circular plate can rotate. When the scraper rotates, the extension plate fixedly connected to the scraper rotates, and the extension plate can scrape the top of the vertical cylinder.

[0016] Preferably, the breaking up mechanism includes a movable plate, a tooth plate and a slide groove, a slide groove is opened on the left side of the upper surface of the first grinding disc, a movable plate is slidably installed inside the slide groove, a tightening mechanism is arranged at the upper surface of the movable plate, a tooth plate is fixedly installed on the lower surface of the movable plate, and the lower surface of the tooth plate is rotatably matched with the second grinding disc, and a cleaning mechanism capable of cleaning the tooth plate is arranged inside the movable plate.

[0017] During operation, when grinding graphene powder, agglomeration is prone to occur, resulting in low grinding efficiency. By setting a breaking mechanism, when the second grinding disc rotates, the tooth plate can rotate relative to the second grinding disc, and the tooth plate can break up the agglomerated graphene powder to improve the grinding efficiency. Since the second grinding disc can move up and down, the particle size of the graphene powder can be controlled. By setting a slide groove and a movable plate, the tooth plate can move along the slide groove to match the position of the second grinding disc.

[0018] Preferably, the cleaning mechanism includes a square groove, an oil cylinder and a cleaning block. The movable plate is provided with evenly distributed square grooves. The inner surfaces of the square grooves are fixedly connected with oil cylinders. The lower surface of the oil cylinder is fixedly connected with a cleaning block, and the cleaning block passes through the movable plate and slides with the inner surface of the tooth plate.

[0019] During operation, when the tooth plate is breaking up the graphene powder, the graphene powder will also be retained in the tooth gaps, causing the tooth plate to be blocked, affecting the breaking performance of the tooth plate. By setting up a cleaning mechanism, it is only necessary to drive the oil cylinder to extend, and the cleaning block fixedly connected to the oil cylinder can move into the tooth gap, pushing out the graphene retained in the tooth gap to avoid clogging of the tooth plate.

[0020] Preferably, the clamping mechanism includes a clamping plate, a cylinder, a cylinder and a spring. A cylinder is fixedly connected to the upper surface of the first grinding disk near the movable plate. The upper surface of the cylinder is fixedly connected to a limiting plate. The outer surface of the cylinder is penetrated by a clamping plate, and the lower surface of the clamping plate presses against the upper surface of the movable plate. A spring is mounted on the outer surface of the cylinder, the upper end of the spring is fixedly connected to the clamping plate, and the lower end of the spring is fixedly connected to the first grinding disk.

[0021] During operation, when the second grinding disk moves downward, the movable plate and the tooth plate move downward accordingly due to their own gravity. However, when the tooth plate encounters agglomerated graphene powder, it may push the tooth plate upward and fail to break up the graphene powder. By setting a clamping mechanism, when the second grinding disk moves upward, it will push the movable plate upward, and the moving upward of the movable plate will drive the clamping plate to move upward, so that the spring fixedly connected to the clamping plate is stretched. The stretched spring has a reverse force on the movable plate and the tooth plate, so that the tooth plate presses against the second grinding disk, thereby preventing the agglomerated graphene powder from pushing up the tooth plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention provides a connecting pipe, a vertical cylinder and a baffle, etc., so that the space for feeding and grinding graphene is closed, thereby preventing the flying of graphene powder during grinding, causing waste of graphene, and improving production efficiency.

[0024] 2. The present invention fixes and connects the hemisphere to the upper surface of the truncated cone-shaped protrusion on the upper surface of the second grinding disc, so that the graphene powder can slide along the hemisphere, avoiding the graphene powder from staying on the upper surface of the truncated cone, thereby ensuring that the graphene powder can be ground.

[0037] A graphene powder production device, such as Figure 1 As shown, it includes a first tank body 1, the lower surface of which is open, and the lower surface of which is fixedly connected with a second tank body 2, and the lower surface of which is fixedly installed with supporting legs 3 distributed in a circular array, and a grinding mechanism 4 capable of grinding graphene is arranged inside the first tank body 1.

[0038] When working, the existing device is easy to generate airflow when in use, which makes graphene powder fly, causing waste of graphene and reducing production efficiency. The present invention can ensure that the graphene is in a closed state when grinding by setting the first tank body 1, the second tank body 2 and the grinding mechanism 4, thereby preventing the graphene powder from flying, reducing the waste of graphene powder and improving production efficiency.

[0039] As an embodiment of the present invention, Figures 1 to 3As shown, the grinding mechanism 4 includes a first grinding disc 41, a second grinding disc 42, a hydraulic rod 43, a connecting column 44, a motor 45, a vertical cylinder 46, a connecting pipe 47, a feed port 48, a discharge port 49, a baffle 410, an elastic sheet 411 and a rotating column 412. The first tank body 1 is fixedly connected with the first grinding disc 41, and the second grinding disc 42 is slidably installed below the first grinding disc 41 in the first tank body 1, and a truncated cone-shaped protrusion is provided in the middle position of the upper surface of the first grinding disc 41 and the second grinding disc 42. The middle position of the lower surface of the second grinding disc 42 is fixedly connected with a hydraulic rod 43, and the lower surface of the hydraulic rod 43 is fixedly connected with a connecting column 44, and the connecting column 44 is rotatably embedded in the middle position of the lower surface of the second tank body 2, and the connecting column 44 passes through the lower surface of the second tank body 2 and is fixedly connected with a motor 45, and a discharge port 49 is fixedly installed on the right side of the lower surface of the second tank body 2. Opening 49, the diameter of the second tank body 2 is larger than the diameter of the first tank body 1, a vertical cylinder 46 is fixedly connected through the middle position of the truncated cone-shaped protrusion on the upper surface of the first grinding disc 41, the upper surface of the vertical cylinder 46 is fixedly connected to the upper surface of the first tank body 1, and a connecting pipe 47 is fixedly connected to the left side of the outer surface of the vertical cylinder 46, the upper end of the connecting pipe 47 passes through the upper surface of the first tank body 1 and is fixedly connected to a feed port 48, the inner surface of the connecting pipe 47 is rotatably connected to a rotating column 412, the outer surface of the rotating column 412 is fixedly connected to a baffle 410, and the outer surface of the baffle 410 is adapted to the inner surface of the connecting pipe 47, an elastic sheet 411 is fixedly connected to the right side of the outer surface of the baffle 410 near the rotating column 412, and the side of the elastic sheet 411 away from the baffle 410 is fixedly connected to the inner surface of the connecting pipe 47, and a scattering mechanism 7 is provided on the left side of the upper surface of the first grinding disc 41.

[0040] During operation, in order to solve the problem that when the upper grinding plate grinds graphene, the airflow generated is easy to make the graphene powder fly and adhere to the inner surface of the grinding chamber, causing the waste of graphene and reducing the production efficiency, a grinding mechanism is set. When in use, first, the graphene powder of uneven thickness is poured into the first tank body 1 through the feed port 48. Since the baffle 410, the elastic sheet 411 and the rotating column 412 are arranged inside the connecting tube 47, when the graphene powder passes through the connecting tube 47, the graphene powder will push the baffle 410 to move to the right, so that the connecting tube 47 is connected with the vertical cylinder 46, and the elastic sheet 411 is in a compressed state at this time. The graphene powder passes through the connecting tube 47 and the vertical cylinder 46 and falls to the upper surface of the second grinding disk 42. Since the middle position of the upper surface of the second grinding disk 42 is a truncated cone shaped protrusion, the graphene powder can fall into the edge of the upper surface of the second grinding disk 42 through the truncated cone inclined surface, driving the hydraulic rod 43 to move up and down, which can drive the hydraulic rod 43 The fixedly connected second grinding disc 42 moves up and down, so that the distance between the first grinding disc 41 and the second grinding disc 42 can be adjusted to control the diameter size of the powder particles. The motor 45 is then connected to an external power source and driven to rotate, thereby driving the hydraulic rod 43 and the second grinding disc 42 to rotate, so that the graphene can be ground. After grinding, the hydraulic rod 43 is driven to move downward, so that the second grinding disc 42 moves down to the second tank body 2. Since the diameter of the second tank body 2 is larger than the diameter of the first tank body 1, when the second grinding disc 42 moves down to the inside of the second tank body 2, the graphene powder on the second grinding disc 42 can slide into the second tank body 2 and then be discharged from the discharge port 49. The present invention provides a connecting pipe 47, a vertical cylinder 46 and a baffle 410, etc., so that the space for feeding and grinding graphene is closed, thereby preventing the flying of graphene powder during grinding, causing waste of graphene, and improving production efficiency.

[0041] As an embodiment of the present invention, Figure 2 As shown, the upper surface of the truncated cone-shaped protrusion on the upper surface of the second grinding disc 42 is fixedly connected with the hemisphere 10 .

[0042] During operation, when the graphene powder is transported into the upper surface of the second grinding disk 42 through the vertical cylinder 46, since the cone on the upper surface of the second grinding disk 42 is horizontal, the graphene powder will stay on the upper surface of the cone and cannot be ground. By fixing the hemisphere 10 on the upper surface of the cone-shaped protrusion on the upper surface of the second grinding disk 42, the graphene powder can slide along the hemisphere 10, avoiding the graphene powder from staying on the upper surface of the cone, thereby ensuring that the graphene powder can be ground.

[0043] As an embodiment of the present invention, Figure 2As shown, a scraper 5 is fixedly connected to the outer surface of the hemisphere 10 , and the outer surface of the scraper 5 is rotatably matched with the inner surface of the vertical cylinder 46 , and an extension mechanism 6 is fixedly installed on the upper surface of the scraper 5 .

[0044] During operation, when the graphene powder is being transported, the graphene powder adheres to the inner surface of the vertical cylinder 46, causing waste. By setting the scraper 5, when the second grinding disc 42 rotates, the scraper 5 fixedly connected to the second grinding disc 42 through the hemisphere 10 rotates accordingly, and the scraper 5 can thereby rotate relative to the vertical cylinder 46, so that the graphene powder on the inner surface of the vertical cylinder 46 can be scraped off, thereby avoiding the waste of graphene powder.

[0045] As an embodiment of the present invention, Figure 4 As shown, the extension mechanism 6 includes an extension plate 61, an annular slide plate 62 and a circular plate 63. The connection between the upper surface of the vertical cylinder 46 and the first tank body 1 is open. The upper surface of the first tank body 1 is coaxially fixedly connected with the vertical cylinder 46 with an annular slide plate 62. The outer surface of the annular slide plate 62 is rotatably embedded with a circular plate 63. The upper surface of the scraper 5 is fixedly connected with the extension plate 61, and the side of the extension plate 61 close to the inner surface of the vertical cylinder 46 is rotatably matched with the vertical cylinder 46. The upper end of the extension plate 61 passes through the circular plate 63 and slidably matches with it.

[0046] During operation, when the second grinding disc 42 moves downward, the scraper 5 also moves downward, and the top of the vertical cylinder 46 cannot be scraped. By setting the extension mechanism 6, when the scraper 5 moves downward, the extension plate 61 connected to the scraper 5 also moves downward. By setting the circular plate 63, the top of the vertical cylinder 46 can be closed. Because the circular plate 63 is connected to the first tank body 1 through the annular slide plate 62, the circular plate 63 can rotate. When the scraper 5 rotates, the extension plate 61 fixedly connected to the scraper 5 rotates, and the extension plate 61 can scrape the top of the vertical cylinder 46.

[0047] As an embodiment of the present invention, Figure 5 As shown, the breaking mechanism 7 includes a movable plate 71, a tooth plate 72 and a slide groove 73. A slide groove 73 is opened on the left side of the upper surface of the first grinding disk 41, and the movable plate 71 is slidably installed inside the slide groove 73. A tightening mechanism 9 is arranged at the upper surface of the movable plate 71. A tooth plate 72 is fixedly installed on the lower surface of the movable plate 71, and the lower surface of the tooth plate 72 is rotatably matched with the second grinding disk 42, and a cleaning mechanism 8 capable of cleaning the tooth plate 72 is arranged inside the movable plate 71.

[0048] During operation, when grinding graphene powder, agglomeration is prone to occur, resulting in low grinding efficiency. By setting up a breaking mechanism 7, when the second grinding disc 42 rotates, the tooth plate 72 can rotate relative to the second grinding disc 42, and the tooth plate 72 can break up the agglomerated graphene powder to improve the grinding efficiency. Since the second grinding disc 42 can move up and down, the particle size of the graphene powder can be controlled. By setting a slide groove 73 and a movable plate 71, the tooth plate 72 can move along the slide groove 73 to match the position of the second grinding disc 42.

[0049] As an embodiment of the present invention, Figure 6 As shown, the cleaning mechanism 8 includes a square groove 81, a cylinder 82 and a cleaning block 83. The movable plate 71 is provided with evenly distributed square grooves 81. The inner surfaces of the square grooves 81 are fixedly connected with the cylinders 82. The lower surfaces of the cylinders 82 are fixedly connected with the cleaning blocks 83. The cleaning blocks 83 penetrate the movable plate 71 and slide with the inner surfaces of the toothed plate 72.

[0050] During operation, when the tooth plate 72 is breaking up the graphene powder, the graphene powder will also be retained in the tooth gaps, causing the tooth plate 72 to be blocked, affecting the breaking performance of the tooth plate 72. By setting up the cleaning mechanism 8, it is only necessary to drive the cylinder 82 to extend, so that the cleaning block 83 fixedly connected to the cylinder 82 can move into the tooth gap, push out the graphene retained in the tooth gap, and avoid blockage of the tooth plate 72.

[0051] As an embodiment of the present invention, Figure 7 As shown, the clamping mechanism 9 includes a clamping plate 91, a cylinder 92, a cylinder 92 and a spring 94. The cylinder 92 is fixedly connected to the upper surface of the first grinding disk 41 near the movable plate 71. The upper surface of the cylinder 92 is fixedly connected to a limiting plate 93. The outer surface of the cylinder 92 is penetrated by the clamping plate 91, and the lower surface of the clamping plate 91 presses against the upper surface of the movable plate 71. The outer surface of the cylinder 92 is covered with a spring 94. The upper end of the spring 94 is fixedly connected to the clamping plate 91, and the lower end of the spring 94 is fixedly connected to the first grinding disk 41.

[0052] During operation, when the second grinding disk 42 moves downward, the movable plate 71 and the tooth plate 72 move downward accordingly due to their own gravity. However, when the tooth plate 72 encounters agglomerated graphene powder, it may push the tooth plate 72 upward and fail to break up the graphene powder. By providing the clamping mechanism 9, when the second grinding disk 42 moves upward, the movable plate 71 will be pushed upward, and the upward movement of the movable plate 71 will drive the clamping plate 91 to move upward, so that the spring 94 fixedly connected to the clamping plate 91 is stretched. The stretched spring 94 has a reverse force on the movable plate 71 and the tooth plate 72, so that the tooth plate 72 presses against the second grinding disk 42, thereby preventing the agglomerated graphene powder from pushing up the tooth plate 72.

[0053] Instructions for use: When the present invention is used, first, graphene powder of uneven thickness is poured into the first tank body 1 through the feed port 48. Since the baffle 410, elastic sheet 411 and rotating column 412 are arranged inside the connecting tube 47, when the graphene powder passes through the connecting tube 47, the graphene powder pushes the baffle 410 to move to the right, so that the connecting tube 47 and the vertical cylinder 46 are aligned. The second grinding disc 42 is connected to each other, and the elastic sheet 411 is in a compressed state at this time. The graphene powder falls onto the upper surface of the second grinding disc 42 through the connecting tube 47 and the vertical cylinder 46. Since the middle position of the upper surface of the second grinding disc 42 is a truncated cone-shaped protrusion, the graphene powder can fall onto the edge of the upper surface of the second grinding disc 42 through the truncated cone slope. The hydraulic rod 43 is driven to move up and down, which can drive the second grinding disc 42 fixedly connected to the hydraulic rod 43 to move up and down, so that the distance between the first grinding disc 41 and the second grinding disc 42 can be adjusted to achieve the control of the diameter size of the powder particles. Then the motor 45 is connected to the external power supply and driven to rotate, so as to drive The hydraulic rod 43 and the second grinding disc 42 rotate, so that the graphene can be ground. After grinding, the hydraulic rod 43 is driven to move downward, so that the second grinding disc 42 moves down to the second tank body 2. Since the diameter of the second tank body 2 is larger than the diameter of the first tank body 1, when the second grinding disc 42 moves down to the inside of the second tank body 2, the graphene powder on the second grinding disc 42 can slide into the second tank body 2 and then be discharged from the discharge port 49. The present invention provides a connecting pipe 47, a vertical cylinder 46 and a baffle 410, etc., so that the space for feeding and grinding graphene is closed, thereby preventing the flying of graphene powder during grinding, causing waste of graphene, and improving production efficiency.
