Description

Technical Field

[0001] This invention relates to the field of graphene suspension preparation technology, and more specifically, to a high-shear preparation device for graphene suspension. Background Technology

[0002] Depending on the properties of the liquids and solids contained in the composition, this can be achieved using rotary mixers employing low-shear or high-shear mixing technologies. The shear rate is determined by the blade design and its rotational speed. Low-shear mixing arrangements typically allow for easy mixing of flowing and turbulent impurities in a vessel. Many mixing epler designs are available for mixing and solid suspension. Hydrofoils, marine-style mixing propellers, axial flow turbines, and radial flow turbines are all black wheel designs that generate water flow. Hydrofoils offer the gentlest mixing with minimal shear. Their blade profile creates a nearly uniform flow rate with minimal horsepower input, making them particularly effective against materials that can be damaged at high speeds, thus requiring higher shear impellers. Large-diameter hydrofoils, driven at low speeds and covering one-third of the vessel diameter, are often chosen for mixing large, messy batches. Marine-style propellers and axial flow turbines are also common. Axial flow turbines are manufactured similarly to hydrofoils but with large, flat blade surfaces at a 45-degree angle, allowing them to contact and agitate more viscous materials. The blade edges are primarily used for flow control processes with higher viscosity, providing higher shear and requiring greater horsepower to drive them. High-shear mixing is used for components that are prone to anti-mixing. Examples include liquids with varying viscosities or liquids containing solids that must be broken down or require forceful action to achieve uniform distribution. Dispersion is a common form of high-shear mixing. Dispersion is a high-speed, high-shear process that requires more power to successfully achieve similar batch sizes than simple stirring. Ideally, deep vortices are visible on the tip surface of the blades. As the dispersing blades rotate, particles come into contact with and break down against the blades. In the intense turbulence around the blades, particles collide at high speeds and are further broken down. Beyond the blade tip, the reduced-size particles are dissolved or dispersed by a horizontal laminar flow extending from the blades. The flow is then split into upward and downward components against the vessel walls, ensuring complete circulation.

[0003] Existing high-shear graphene suspension preparation devices cannot stably and uniformly perform high-speed shearing on the upper and lower parts of the graphene suspension, which easily leads to low mixing efficiency. Furthermore, when performing high-speed shearing on high liquid levels, the liquid level is prone to rise excessively, resulting in overflow. Therefore, we have made improvements and proposed a high-shear graphene suspension preparation device. Summary of the Invention

[0004] The purpose of this invention is to address the problem that current high-shear preparation devices for graphene suspensions cannot stably and uniformly perform high-speed shearing on the upper and lower parts of the graphene suspension, which easily leads to low mixing efficiency. Furthermore, when performing high-speed shearing on high liquid levels, the liquid level is easily raised too much, resulting in overflow.

[0006] A high-shear preparation device for graphene suspensions is proposed to improve the above-mentioned problems.

[0007] The application is as follows:

[0011] An anti-overflow assembly includes an annular track embedded in the inner end of the mixing chamber, a linkage ring wrapped around the outer end of the threaded shaft, and a movable sector plate that rotates within the mixing chamber.

[0012] As a preferred technical solution of this application, the central shaft is fixedly connected to the linkage rotating plate, the bevel gear is fixedly installed at both ends of the linkage rotating plate, the outer end of the bevel gear is meshed with the linkage bevel gear rod, and a movable seat is provided between the linkage rotating plate and the forward threaded block and the reverse threaded block.

[0013] As a preferred technical solution of this application, the forward threaded block and the reverse threaded block rotate along the movable seat at both ends of the linkage rotating plate. The outer end of the linkage rotating plate is provided with a groove, and the outer end of the groove is provided with a sliding ring. The sliding ring wraps around the outer end of the threaded shaft.

[0014] As a preferred technical solution of this application, the inner end of the sliding ring has an inner through hole, the inner end of the inner through hole is provided with an inner positioning rod, the lower end of the inner positioning rod is provided with an inner positioning slider, and the outer end of the inner positioning slider is provided with a ring rail.

[0015] As a preferred technical solution of this application, the ring rail is embedded in the upper inner surface of the base plate, the inner positioning slider rotates along the ring rail, and the upper end of the inner positioning rod is fixedly connected to the upper inner surface of the mixing chamber.

[0016] As a preferred technical solution of this application, the outer end of the linkage bevel gear is provided with a positioning ring, the outer end of the positioning ring is provided with a movable groove, the movable groove is embedded in the inner end of the sliding ring, the positioning ring and the movable groove are fixedly connected, and one of the bevel gears is provided with a micro motor at its outer end.

[0017] As a preferred technical solution of this application, a first spring is provided between the inner slide cylinder and the positioning slide rod. The first spring is wrapped around the outer end of the positioning slide rod. The outer end of the outer positioning rod is provided with an outer through hole, and the outer through hole passes through the outer surfaces of the upper and lower ends of the dispersing blade.

[0018] As a preferred technical solution of this application, the upper end of the outer positioning rod is provided with an upper linkage ring, and the upper linkage ring is fixedly connected to the threaded shaft.

[0019] As a preferred technical solution of this application, the outer end of the linkage ring is provided with a first extension rod, the outer end of the first extension rod is provided with a telescopic rod, the inner end of the telescopic rod is provided with a second spring, the outer end of the telescopic rod is provided with a second extension rod, the second extension rod is movably connected to the tail end of the movable sector plate, and the head end of the movable sector plate is connected with a movable connecting block.

[0020] As a preferred technical solution of this application, a rotating ring is fixedly installed on the outer end of the movable connecting block, the rotating ring is embedded in the inner end of the annular track, and a third spring is provided between the linkage ring and the upper linkage ring.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the scheme of this application:

[0023] 1. By setting up an up-and-down sliding adjustment component, the rotation of the micro motor drives the central shaft connected by the bevel gear and the linkage bevel gear rod to rotate in the opposite direction. At this time, the forward threaded block is in contact with the threaded shaft. When the threaded shaft rotates, the sliding ring can move upward stably through the limit between the inner positioning rod and the inner through hole. During the upward movement, the dispersing blade can stably rotate the high-shear graphene suspension. When the sliding ring reaches the top and needs to change the direction of movement, the micro motor drives the central shaft connected by the bevel gear and the linkage bevel gear rod to rotate clockwise. The reverse threaded block is in contact with the threaded shaft. At this time, the dispersing blade descends during the rotation driven by the threaded shaft, which can ensure more efficient high shear for the graphene suspension and avoid the energy consumption problem caused by the forward and reverse rotation of the threaded shaft.

[0024] 2. By setting up a rotating inner diameter adjustment component, the outer positioning rod is positioned obliquely through the outer through hole at the upper and lower ends of the dispersing blade. The upper end of the outer positioning rod is fixedly connected to the threaded shaft through the upper linkage ring. When the sliding ring drives the dispersing blade to move upward, the rotation radius of the dispersing blade can be realized through the outer positioning rod. Furthermore, the positioning slide rod and the first spring connected by the inner slide cylinder ensure the sliding stability between the dispersing blade and the outer positioning rod, and can maintain the connection between the dispersing blade and the sliding ring.

[0025] 3. By incorporating an anti-overflow component, the movable sector plate rotates along the movable connecting block. When the dispersing scraper is at the bottom of the mixing chamber, the movable sector plate is inverted conical. When the dispersing scraper moves upward and the sliding ring contacts the linkage ring, the sliding ring drives the linkage ring to move upward, compressing the third spring. At this time, the first extension rod located at the outer end of the linkage ring drives the telescopic rod connected to the outer end and the second extension rod to retract, compressing the second spring. At this time, the movable sector plate connected to the second extension rod and the movable connecting block gradually rotates until all movable sector plates are horizontal. After the movable sector plate rotates, it can increase the area covered by the graphene suspension. It also blocks the upward movement of the graphene suspension level caused by the reduced vortex after the dispersing blade moves upward, thus preventing overflow.

[0026] 4. By incorporating a sliding adjustment component, the inner diameter adjustment component and the anti-overflow component can be stably moved up and down, ensuring a stable power source. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of the present invention can be combined with each other.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] like Figure 1-9As shown, this embodiment proposes a high-shear preparation device for graphene suspension, including a high-shear mixer 1 and a mixing chamber 2 fixed to the left end of the high-shear mixer 1. The inner end of the mixing chamber 2 is provided with a threaded shaft 3, and the lower end of the threaded shaft 3 is provided with a base plate 4. The base plate 4 is fixedly installed at the lower end of the threaded shaft 3. The outer end of the threaded shaft 3 is provided with a dispersing blade 21. The device also includes an up-and-down sliding adjustment assembly, which includes a forward threaded block 12 and a reverse threaded block 13 for adjusting up-and-down movement, a linkage rotating plate 14 for adjusting the forward threaded block 12 and the reverse threaded block 13, a central shaft 11, a bevel gear 16, and a linkage bevel gear rod 17 for rotating the linkage rotating plate 14. The forward threaded block 12 and the reverse threaded block 13 are movably connected to the upper and lower ends of the linkage rotating plate 14. The central shaft 11 is fixedly connected to the linkage rotating plate 14. The bevel gear 16 is fixedly installed at both ends of the linkage rotating plate 14. The outer end of the bevel gear 16 is meshed with the linkage bevel gear rod 17. A movable seat 15 is provided between the linkage rotating plate 14 and the forward threaded block 12 and the reverse threaded block 13. The forward threaded block 12 and the reverse threaded block 13 rotate along the movable seat 15 at both ends of the linkage rotating plate 14. The outer end of the linkage rotating plate 14 is provided with a groove 10. The outer end of the groove 10 is provided with a sliding ring 9. The sliding ring 9 wraps around the outer end of the threaded rotating shaft 3. The inner end of the sliding ring 9 has an inner through hole 8. The inner end of the inner through hole 8 is provided with an inner positioning rod 6. The lower end of the inner positioning rod 6 is provided with an inner positioning slider 7. The outer end of the inner positioning slider 7 is provided with a ring rail 5. The ring rail 5 is embedded in the upper inner surface of the base plate 4. The inner positioning slider 7 rotates along the ring rail 5. The upper end of the inner positioning rod 6 is fixedly connected to the upper inner surface of the mixing chamber 2.The outer end of the linkage bevel gear 17 is provided with a positioning ring 18, and the outer end of the positioning ring 18 is provided with a movable groove 19. The movable groove 19 is embedded in the inner end of the sliding ring 9, and the positioning ring 18 and the movable groove 19 are fixedly connected. One of the bevel gears 16 is provided with a micro motor 20 at its outer end. By setting up a sliding adjustment component, when the dispersing blade 21 connected to the outer end of the sliding ring 9 needs to move stably up and down in the mixing chamber 2, when the sliding ring 9 moves up, the micro motor 20 rotates, driving the central shaft 11 connected to the bevel gear 16 and the linkage bevel gear 17 to rotate in the opposite direction. At this time, the forward thread block 12... When the threaded shaft 3 rotates, the sliding ring 9 can move upward stably through the limit between the inner positioning rod 6 and the inner through hole 8. During the upward movement, the dispersing blade 21 can stably rotate the high-shear graphene suspension. When the sliding ring 9 reaches the top and needs to change its direction of movement, the central shaft 11 connected to the bevel gear 16 and the linkage bevel gear rod 17 is driven by the micro motor 20 to rotate clockwise. The reverse threaded block 13 is in contact with the threaded shaft 3. At this time, the dispersing blade 21 descends during the rotation driven by the threaded shaft 3, which can ensure more efficient high shearing of the graphene suspension.

[0048] like Figure 10 As shown, in a preferred embodiment, based on the above method, a rotating inner diameter adjustment assembly is further provided. The rotating inner diameter adjustment assembly includes a positioning slide rod 23 located at the outer end of the sliding ring 9, an inner slide cylinder 22 embedded in the inner end of the dispersing blade 21, and an outer positioning rod 26 for limiting the up-and-down movement of the dispersing blade 21. The outer positioning rod 26 is fixedly connected to the base plate 4. A first spring 24 is provided between the inner slide cylinder 22 and the positioning slide rod 23. The first spring 24 wraps around the outer end of the positioning slide rod 23. The outer end of the outer positioning rod 26 is provided with an outer through hole 25, and the outer through hole 25 penetrates the outer surfaces of the upper and lower ends of the dispersing blade 21. The upper end of the outer positioning rod 26 is provided with an upper linkage ring 27, and the upper linkage ring 27 is fixedly connected to the threaded rotating shaft 3. By providing a rotation inner diameter adjustment component, when the dispersing blade 21 needs to be moved upward, the rotation vortex radius of the graphene suspension can be reduced to prevent overflow of the mixing chamber 2. At this time, the oblique outer positioning rod 26 is positioned at the upper and lower ends of the dispersing blade 21 through the outer through hole 25, so that the upper end of the outer positioning rod 26 is fixedly connected to the threaded rotating shaft 3 through the upper linkage ring 27. When the sliding ring 9 drives the dispersing blade 21 to move upward, the rotation radius of the dispersing blade 21 can be realized through the outer positioning rod 26. Furthermore, the positioning slide rod 23 and the first spring 24 connected by the inner slide cylinder 22 ensure the sliding stability between the dispersing blade 21 and the outer positioning rod 26, and can maintain the connection between the dispersing blade 21 and the sliding ring 9.

[0049] like Figure 11-12As shown, in a preferred embodiment, based on the above method, a further anti-overflow component is provided. The anti-overflow component includes an annular track 28 embedded in the inner end of the mixing chamber 2, a linkage ring 29 wrapped around the outer end of the threaded shaft 3, and a movable sector plate 34 rotating within the mixing chamber 2. The outer end of the linkage ring 29 is provided with a first extension rod 30, the outer end of the first extension rod 30 is provided with a telescopic rod 31, the inner end of the telescopic rod 31 is provided with a second spring 32, the outer end of the telescopic rod 31 is provided with a second extension rod 33, the second extension rod 33 is movably connected to the tail end of the movable sector plate 34, and the head end of the movable sector plate 34 is connected with a movable connecting block 35. A rotating ring 36 is fixedly installed on the outer end of the movable connecting block 35. The rotating ring 36 is embedded in the inner end of the annular track 28. A third spring 37 is provided between the linkage ring 29 and the upper linkage ring 27. An anti-overflow component is provided. When the dispersing blade 21 needs to move upward, it drives the graphene suspension to rotate in a vortex. At this time, the movable sector plate 34 rotates along the movable connecting block 35. When the dispersing scraper is at the bottom of the mixing chamber 2, the movable sector plate 34 is inverted conical. When the dispersing scraper moves upward and the sliding ring 9 contacts the linkage ring 29, this... When the sliding ring 9 moves the linkage ring 29 upward, it compresses the third spring 37. At this time, the first extension rod 30 located at the outer end of the linkage ring 29 drives the telescopic rod 31 connected to the second extension rod 33 to contract, compressing the second spring 32. At this time, the movable sector plate 34 connected to the second extension rod 33 and the movable connecting block 35 gradually rotates until all the movable sector plates 34 are horizontal. After the movable sector plates 34 rotate, the area covered by the upper end of the graphene suspension can be increased. This also blocks the upward movement of the graphene suspension level caused by the vortex decreasing after the dispersing blade 21 moves upward, preventing overflow.

[0050] In use, when the sliding ring 9 moves upward, the micro motor 20 rotates, driving the central shaft 11, which is connected to the bevel gear 16 and the linkage bevel gear rod 17, to rotate in the opposite direction. At this time, the forward threaded block 12 is in contact with the threaded shaft 3. When the threaded shaft 3 rotates, the sliding ring 9 can move upward stably through the limit between the inner positioning rod 6 and the inner through hole 8. During the upward movement, the dispersing blade 21 can stably rotate the high-shear graphene suspension. When it is necessary to reduce the graphene suspension when the dispersing blade 21 moves upward, it can reduce the high-shear graphene suspension. The radius of the rotating vortex of the flotation liquid is adjusted to prevent overflow from the mixing chamber 2. When the dispersing scraper is at the bottom of the mixing chamber 2, the movable sector plate 34 is inverted conical. When the sliding ring 9 contacts the linkage ring 29, the sliding ring 9 drives the linkage ring 29 to move upward, compressing the third spring 37. At this time, the first extension rod 30 located at the outer end of the linkage ring 29 drives the telescopic rod 31 connected to the second extension rod 33 to contract, compressing the second spring 32. At this time, the movable sector plate 34 connected to the second extension rod 33 and the movable connecting block 35 gradually rotates. When all movable sector plates 34 are level, the area covered by the upper part of the graphene suspension is increased after the movable sector plates 34 rotate. This prevents the vortex from decreasing after the dispersing blade 21 moves upward, but still causes the liquid level of the graphene suspension to rise, thus preventing overflow. During the upward movement of the sliding ring 9, the upper and lower ends of the dispersing blade 21 are positioned by the oblique outer positioning rod 26 through the outer through hole 25. The upper end of the outer positioning rod 26 is fixedly connected to the threaded shaft 3 through the upper linkage ring 27. The sliding ring 9 drives the dispersing blade 21 upward... When moving, the rotation radius of the dispersing blade 21 can be achieved by the outer positioning rod 26, and the positioning slide rod 23 and the first spring 24 connected by the inner slide cylinder 22 ensure the sliding stability between the dispersing blade 21 and the outer positioning rod 26, and can maintain the connection between the dispersing blade 21 and the sliding ring 9. When the sliding ring 9 reaches the top and needs to change the direction of movement, the central shaft 11 connected by the bevel gear 16 and the linkage bevel gear rod 17 is driven by the micro motor 20 to rotate clockwise, and the reverse threaded block 13 is in contact with the threaded rotating shaft 3.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
