Description

Technical Field

[0001] The present invention relates to the technical field of graphene production. More specifically, the present invention relates to a graphene raw material solution mixing device. Background Art

[0002] During the production and processing of graphene, a large amount of organic solvents and electrolyte solutions are required. When the existing equipment mixes and prepares such solutions, during the stirring process, clean water needs to be added to the solution at regular times and fixed points. The prior art directly pours the clean water onto the surface of the solution, resulting in the need for long-term stirring to evenly mix the clean water and the solution; Therefore, the Chinese patent with the publication number "CN217450017U" discloses a raw material mixing device for graphene production. It evenly opens a circle of round holes on the stirring barrel cover, and conveys clean water to the surface of the solution through the entire circle of round holes, so that the clean water is evenly poured onto the upper layer of the solution, and then the stirring operation is carried out. That is, the pre-mixing effect is achieved while injecting the clean water, which is beneficial to shortening the time spent stirring to the uniform state; Although the above device achieves the pre-mixing effect while injecting the clean water, after injecting the clean water into the solution through the entire circle of round holes, the clean water is still distributed on the upper layer of the solution, resulting in a low pre-mixing effect. Summary of the Invention

[0003] In order to overcome the drawback that although the existing device achieves the pre-mixing effect while injecting the clean water, its pre-mixing effect is low, the present invention provides a graphene raw material solution mixing device.

[0005] Furthermore, the feeding assembly includes a second cylinder and a cylinder cover; the second cylinder is fixedly connected to the top cover; the cylinder cover is rotatably connected to the second cylinder.

[0006] Furthermore, the material discharging assembly includes a valve and a pipeline; a valve is fixedly connected to the first cylinder; a pipeline is fixedly connected to the valve.

[0007] Furthermore, a plurality of third cavities are formed on the edge of the stirring blade far away from the hollow rod, the third cavities communicate with the corresponding first cavities, and the third cavities communicate with the corresponding second cavities; the third cavities are in a horn shape.

[0008] Furthermore, a switching assembly is further included; a switching assembly is fixedly connected to the first round tube; the switching assembly includes a first ring, a second ring, an electric push rod and a connecting block; the first ring is fixedly connected to the first round tube; the second ring is fixedly connected to the hollow rod, and the second ring contacts the first ring; an electric push rod is fixedly connected to the top cover; the telescopic end of the electric push rod is fixedly connected to the connecting block, and the connecting block is rotatably connected to the first round tube.

[0009] Furthermore, a guiding block is further included; a guiding block is fixedly connected to each stirring blade, and the guiding block contacts the hollow rod; the upper sides of the first ring and the second ring are both provided with inclined surfaces.

[0014] The present invention has the following advantages: 1.

After the mixing is completed, during the cleaning process, clear water can also be sprayed onto the inner wall of the first cylinder at a high speed through the first cavities, washing away the viscous liquid remaining on the inner wall of the first cylinder, greatly reducing the cleaning difficulty, and thus improving the convenience; 2.

Moreover, the downward movement of the first round tube, which is originally required to move downward, is used to control the downward movement of the round rod to insert into the third cylinder to achieve the blocking operation, without the need to set an additional electric driving part to control the round rod, and the structure is ingenious.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1 A graphene raw material solution mixing device, as Figures 1-5As shown in the figure, it includes a first cylinder 1, a support 2 and a top cover 3; four supports 2 are bolted to the first cylinder 1, and the supports 2 are made of alloy material; a top cover 3 is bolted to the first cylinder 1; it also includes a hollow rod 4, a stirring blade 5, a first round tube 6, a second round tube 7, a motor 8, a speed reducer 9, a feeding assembly and a discharging assembly; the hollow rod 4 is rotatably connected to the top cover 3; two stirring blades 5 are welded to the hollow rod 4, and the liquid in the first cylinder 1 is stirred by the stirring blades 5; the first round tube 6 is slidably connected to the hollow rod 4; the second round tube 7 is rotatably connected to the first round tube 6; a motor 8 is arranged above the top cover 3; the output end of the motor 8 is connected to the speed reducer 9, the speed reducer 9 is bolted to the top cover 3, and the output end of the speed reducer 9 is connected to the hollow rod 4; a number of first cavities 91 are formed in each stirring blade 5, and the first cavities 91 communicate with the hollow rod 4; four second cavities 92 are formed in each stirring blade 5, and the second cavities 92 communicate with the corresponding first cavities 91; the width of the uppermost first cavity 91 in each stirring blade 5 is greater than the widths of the other first cavities 91; a feeding assembly is connected to the top cover 3; a discharging assembly is connected to the first cylinder 1.

[0019] The feeding assembly includes a second cylinder 201 and a cylinder cover 202; the second cylinder 201 is welded to the top cover 3, and the second cylinder 201 is made of alloy material; the cylinder cover 202 is rotatably connected to the second cylinder 201.

[0020] The discharging assembly includes a valve 203 and a pipeline 204; the valve 203 is bolted to the first cylinder 1; the pipeline 204 is bolted to the valve 203, and when the valve 203 is opened, the solution in the first cylinder 1 is discharged through the pipeline 204.

[0021] A number of third cavities 93 are formed on the edge of the stirring blade 5 away from the hollow rod 4, the third cavities 93 communicate with the corresponding first cavities 91, and the third cavities 93 communicate with the corresponding second cavities 92; the third cavities 93 are in a horn shape.

[0022] First, connect the external water inlet pipe to the second circular pipe 7. Manually open the cylinder cover 202, then pour the raw material solution into the first cylinder 1 from the second cylinder 201, and then close the cylinder cover 202. Start the motor 8. The motor 8 drives the hollow rod 4 to rotate through the speed reducer 9. The hollow rod 4 drives the first circular pipe 6 to rotate, while the second circular pipe 7 is fixed on the external water inlet pipe and remains stationary. The hollow rod 4 drives the stirring blade 5 to rotate, and the solution in the first cylinder 1 is stirred by the stirring blade 5. When it is necessary to inject clean water, clean water is conveyed to the second circular pipe 7 through the external water inlet pipe. The clean water flows into the first circular pipe 6 through the second circular pipe 7, then flows into the hollow rod 4 through the first circular pipe 6, and then flows from the hollow rod 4 into the first cavity 91, and then flows into the solution from the end of the first cavity 91. Thus, while injecting clean water, the clean water can be premixed at various depth positions of the solution, greatly improving the mixing efficiency. After mixing is completed, turn off the motor 8. Manually place the external collection bucket below the pipe 204, and then unscrew the valve 203 to make the solution in the first cylinder 1 flow into the external collection bucket through the pipe 204, completing the stirring and mixing operation.

[0023] After stirring relatively viscous liquid, the viscous liquid will adhere to the inner wall of the first cylinder 1 and is relatively difficult to clean. Therefore, during cleaning, clean water is conveyed to the second circular pipe 7 through the external water inlet pipe. The clean water flows into the first circular pipe 6 from the second circular pipe 7, then flows into the hollow rod 4 from the first circular pipe 6, and then flows from the hollow rod 4 into the first cavity 91, and then is sprayed from the first cavity 91 onto the inner wall of the first cylinder 1. At this time, start the motor 8. The motor 8 drives the hollow rod 4 to rotate through the speed reducer 9. The hollow rod 4 drives the stirring blade 5 to rotate, so that the clean water impacts the inner wall of the first cylinder 1 in a circumferential manner, thereby flushing away the viscous liquid remaining on the inner wall of the first cylinder 1. At the same time, the clean water in the two uppermost first cavities 91 will flow into the second cavity 92, and then be sprayed from the second cavity 92 onto the bottom of the top cover 3, flushing away the viscous liquid remaining on the bottom of the top cover 3. Continuously inject clean water to make the clean water overflow the stirring blade 5, and the stirring blade 5 continues to rotate, thereby cleaning the viscous liquid remaining on the stirring blade 5. Then unscrew the valve 203 to discharge the waste liquid generated during cleaning. During use, by opening the first cavity 91 on the stirring blade 5, during the process of stirring the solution, clean water can be injected into various depth positions of the solution through the first cavity 91, greatly improving the mixing efficiency. After mixing is completed, during the cleaning process, clean water can also be sprayed onto the inner wall of the first cylinder 1 at a high speed through the first cavity 91, flushing away the viscous liquid remaining on the inner wall of the first cylinder 1, greatly reducing the cleaning difficulty, and thus improving the convenience.

[0024] During the cleaning process, since the widths of the two uppermost first cavities 91 are larger than those of the other first cavities 91, more clean water can flow into the two uppermost first cavities 91, so that there is enough clean water spraying upward from the second cavity 92 to ensure the flushing effect on the lower side of the top cover 3.

[0025] During the cleaning process, a horn-shaped cavity three 93 is arranged in the cavity one 91, so that the clear water flows out of the cavity three 93 and sprays onto the inner wall of the cylinder one 1 in a diffused form, expanding the contact area between each stream of clear water and the inner wall of the cylinder one 1, so that each position on the inner wall of the cylinder one 1 can be impacted by the clear water to ensure the flushing effect of the inner wall of the cylinder one 1 and the lower side of the top cover 3.

[0026] Embodiment 2 On the basis of Embodiment 1, as Figures 3-6 shown, it further includes a switching component; a switching component is bolted to the round tube one 6; the switching component includes a ring one 205, a ring two 206, an electric push rod 207 and a connecting block 208; the ring one 205 is fixedly connected to the round tube one 6; the ring two 206 is fixedly connected to the hollow rod 4, and the ring two 206 contacts the ring one 205. Through the cooperation of the ring one 205 and the ring two 206, the inner side of the hollow rod 4 is divided into upper and lower parts; the electric push rod 207 is bolted to the top cover 3; the telescopic end of the electric push rod 207 is fixedly connected to the connecting block 208, and the connecting block 208 is rotatably connected to the round tube one 6, and the connecting block 208 is made of alloy material.

[0027] It further includes a diversion block 209; a diversion block 209 is welded to each stirring blade 5, and the diversion block 209 contacts the hollow rod 4 to divert the liquid through the diversion block 209; the upper sides of the ring one 205 and the ring two 206 are both provided with inclined surfaces.

[0028] To ensure the flushing effect, the first cavity 91 should be evenly distributed at various positions of the stirring blade 5. However, during the stirring process, the solution in the first cylinder 1 cannot be filled up, that is, the ports of some of the first cavities 91 are located above the solution. At this time, when clear water is injected into the solution through the first cavity 91, some of the clear water will flow out from the first cavity 91 located above the solution and flow into the upper layer of the solution, resulting in too much clear water in the upper layer of the solution, thus affecting the stirring effect. Therefore, during the stirring process, through the cooperation of the first ring 205 and the second ring 206, the inner side of the hollow rod 4 is divided into upper and lower two spaces, and the height of the first cavity 91 communicated with the lower space of the hollow rod 4 is lower than the liquid level of the solution. After the clear water flows into the first pipe 6 through the second pipe 7, it will flow from the first pipe 6 into the lower space of the hollow rod 4, then flow into the first cavity 91 below the liquid level of the solution, and finally flow into the solution, thus avoiding the problem of disturbing the stirring due to a large amount of clear water flowing into the upper layer of the solution. During cleaning, the electric push rod 207 is started, and the electric push rod 207 drives the connecting block 208 to move downward. The connecting block 208 drives the first pipe 6 to move downward, and the first pipe 6 drives the first ring 205 to move downward away from the second ring 206, so that the first ring 205 and the second ring 206 stop separating the hollow rod 4, so that clear water can flow into the inner sides of all the first cavities 91 to fully clean the first cylinder 1 and the top cover 3. During use, through the cooperation of the first ring 205 and the second ring 206, during the stirring process, the clear water injected from the second pipe 7 can only flow into the first cavity 91 below the liquid level of the solution and then flow into the solution, thus avoiding the problem of disturbing the stirring due to a large amount of clear water flowing into the upper layer of the solution.

[0029] During the stirring process, some of the solution will splash and splash into the first cavity 91 above the solution, and then flow into the upper space of the hollow rod 4 through the first cavity 91, which is difficult to take out, resulting in the problem of insufficient stirring. Therefore, the upper sides of both the first ring 205 and the second ring 206 are set as inclined surfaces, and the lowest point of the upper side of the second ring 206 is aligned with the highest point of the diversion block 209. After the solution flows into the upper space of the hollow rod 4, it will flow to the upper sides of the first ring 205 and the second ring 206, then flow along the upper sides of the first ring 205 and the second ring 206 to the upper side of the diversion block 209, and then flow back into the first cylinder 1 along the upper side of the diversion block 209 to re-participate in the stirring operation. During use, through the cooperation of the first ring 205, the second ring 206 and the diversion block 209, the solution splashed into the upper space of the hollow rod 4 is diverted back into the first cylinder 1 to re-participate in the stirring operation, avoiding the problem of insufficient stirring.

[0030] Embodiment 3 On the basis of Embodiment 2, as Figures 4-7 shown, it further includes a third cylinder 2010; the lower end of the hollow rod 4 is fixedly connected to the third cylinder 2010.

[0031] It further includes a round rod 2011; a round rod 2011 is fixedly connected to the first round tube 6, and the round rod 2011 is used to block the third cylinder 2010.

[0032] It further includes a spiral blade 2012; a spiral blade 2012 is fixedly connected to each stirring blade 5. When the stirring blade 5 drives the spiral blade 2012 to rotate, the spiral blade 2012 can lift the solution upward, thereby improving the stirring effect.

[0033] The upper part of the round rod 2011 is conical, so that the water flow in the first round tube 6 flows out more smoothly.

[0034] During the stirring process, part of the clear water in the hollow rod 4 will be sprayed downward from the third cylinder 2010 and rush into the lowermost end of the first cylinder 1, so that the solution here surges upward to the stirring area, and the stirring blade 5 fully stirs it. When in use, when clear water is conveyed into the solution through the hollow rod 4, the clear water can make the solution at the lowermost end of the first cylinder 1 surge upward to the stirring area, which is beneficial to improving the stirring effect.

[0035] During the cleaning process, part of the clear water in the hollow rod 4 will be sprayed downward from the third cylinder 2010, resulting in a relatively low water pressure inside the hollow rod 4, and thus a relatively low impact force of the clear water sprayed from the first cavity 91 and the second cavity 92, affecting the cleaning effect. Therefore, during cleaning, when the electric push rod 207 controls the first round tube 6 to move downward, the first round tube 6 will also drive the round rod 2011 to move downward, so that the round rod 2011 is inserted into the third cylinder 2010 to block the third cylinder 2010, so that the clear water has sufficient pressure to be sprayed from the first cavity 91 and the second cavity 92 to ensure the cleaning effect. When in use, the third cylinder 2010 is blocked by the round rod 2011, so that the clear water has sufficient pressure to be sprayed from the first cavity 91 and the second cavity 92 to ensure the cleaning effect of the first cylinder 1 and the top cover 3. Moreover, the downward movement of the first round tube 6, which is originally required, is used to control the downward movement of the round rod 2011 to insert into the third cylinder 2010 to achieve the blocking operation, without setting an additional electric drive member to control the round rod 2011, and the structure is ingenious.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
