Description

Technical Field

[0001] The utility model relates to the technical field of graphene production, in particular to a stirring device for graphene production. Background Art

[0002] Graphene is an allotrope of carbon, and carbon atoms are bonded by sp 2 hybridization to form a single-layer hexagonal honeycomb lattice graphene. Using this crystal structure of graphene, fullerenes (C60), graphene quantum dots, carbon nanotubes, nanoribbons, multi-walled carbon nanotubes, and nanohorns can be constructed. Stacked graphene layers (more than 10 layers) form graphite, and the layers are held together by van der Waals forces, with an interplanar spacing of 0.335 nanometers. Graphene has excellent optical, electrical, and mechanical properties and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered a revolutionary material for the future.

[0003] In the process of graphene production, the mixing and stirring of raw materials are key steps. However, during the stirring process, the raw materials may adhere to the inner wall of the stirring cylinder.

The traditional cleaning method for stirring equipment is usually to directly inject water into the stirring cylinder and clean it by running the equipment. However, the cleaning effect of this method is not ideal, and there may still be residual materials on the inner wall of the stirring cylinder. To improve the cleaning effect, some existing equipment has installed special cleaning devices inside the stirring cylinder. Nevertheless, the structure of these devices becomes more complex, and the cleaning effect is still not satisfactory.

[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments, but it is not a limitation of the present utility model.

[0024] In the description of the present utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0025] Please refer to Figures 1-3 As shown, a stirring device for graphene production is shown, which includes a stirring cylinder body 1, a stirring shaft 2, stirring rods 3 and a motor 4. The stirring shaft 2 passes through the top end of the stirring cylinder body 1. A plurality of stirring rods 3 are connected to the side wall of the stirring shaft 2. The motor 4 is installed at the top end of the stirring cylinder body 1. The stirring shaft 2 is a hollow shaft, and the stirring rods 3 are hollow stirring rods. A plurality of stirring rods 3 are all communicated with the stirring shaft 2. A first gear 5 is installed at the output end of the motor 4, and a second gear 6 is installed at the upper part of the stirring shaft 2. The first gear 5 meshes with the second gear 6. The motor 4 is used to drive the stirring shaft 2 to rotate;

[0026] It further includes a water pump 7, a water inlet pipe 8, a rotary joint 9 and a spray head 10. The water pump 7 is arranged outside the stirring cylinder body 1. The water pump is preferably a high-pressure water pump. The rotary joint 9 is installed at the top end of the stirring cylinder body 1. One end of the water inlet pipe 8 is connected to the water pump 7, and the other end of the water inlet pipe 8 is connected to the rotary joint 9. The rotary joint 9 is communicated with the stirring shaft 2. The stirring shaft 2 is communicated with the water inlet pipe 8 through the rotary joint 9. A spray head 10 is installed at one end of each stirring rod 3 away from the stirring shaft 2. A plurality of nozzles 11 are arranged on the spray head 10. The nozzles 11 are distributed on both sides of the spray head 10. A plurality of nozzles 11 on one side of each spray head 10 all face the inner wall of the stirring cylinder body 1, and a plurality of nozzles 11 on the other side of each spray head 10 all face the stirring shaft 2. Preferably, three nozzles 11 are arranged on the side of each spray head 10 facing the inner wall of the stirring cylinder body 1, and two nozzles 11 are arranged on the other side of each spray head 10. The spray head 10 and the nozzles 11 are preferably made of alloy materials to increase their wear resistance.

[0027] Further, multiple rows of stirring rods 3 are axially connected along the stirring shaft 2. The multi-row design can increase the stirring and flushing effects. The distance range between any two adjacent spray heads 10 in each row of stirring rods 3 is 0 - 5 cm. Setting a suitable distance between the spray heads 10 can enable the water sprayed by the nozzles 11 to fully cover the inner side wall of the stirring cylinder body 1.

[0028] Further, the stirring cylinder body 1 includes a cylinder top 1001, a cylinder wall 1002 and a cylinder bottom 1003. The cylinder top 1001 is detachably installed at the top end of the cylinder wall 1002, and the cylinder wall 1002 is integrally connected to the cylinder bottom 1003.

[0029] Further, the spray head 10 is detachably connected to the stirring rod 3. The spray head 10 and the stirring rod 3 can be connected by threads or pins. Due to long-term use, the spray head 10 may be blocked or damaged. Therefore, the spray head 10 can be removed for replacement.

[0030] Further, it also includes handles 12. One handle 12 is installed at each end of the top 1001 of the cylinder body. When it is necessary to remove the top 1001 of the cylinder body, the top 1001 of the cylinder body can be removed from the cylinder wall 1002 through the handles 12.

[0031] Further, the horizontal height of the bottom 1003 of the cylinder body gradually decreases from the edge to the center, and the bottom 1003 of the cylinder body is in an inverted conical shape. In this way, it is more convenient for the material to flow out of the discharge port 14. Moreover, when it is necessary to wash the stirring cylinder body 1, the flushing material is more likely to be discharged from the discharge port 14.

[0032] Further, the axis of the stirring rod 3 forms an angle with the horizontal direction, and the horizontal height near the stirring shaft 2 is lower than the horizontal height near the nozzle 10. The central axis of the stirring rod 3 forms an angle with the horizontal direction, and the stirring rod 3 is inclined, which can make the residues on the stirring rod 3 flow away more easily.

[0033] Further, a feed port 13 is provided at the top end of the stirring cylinder body 1, and a discharge port 14 is provided at the bottom end of the stirring cylinder body 1. A valve is installed at the discharge port 14 to control the opening and closing of the discharge port 14.

[0034] Further, it also includes support columns 15. The support columns 15 are installed at the bottom end of the stirring cylinder body 1, and there are 4 support columns 15, which are symmetrically arranged in pairs at the edge of the bottom end of the stirring cylinder body 1. The support columns 15 can be used to stabilize the stirring cylinder body 1. At the same time, a discharging space is left at the discharge port 14.

[0035] In a preferred embodiment, a nozzle 10 is connected to the bottom end of the stirring shaft 2. In this way, the flushing effect at the bottom can be increased.

[0036] In a preferred embodiment, the water pump 7 is installed at the top end of the stirring cylinder body 1. One end of the water inlet pipe 8 is connected to the water pump 7, and the other end of the water inlet pipe 8 is connected to the rotary joint 9. The rotary joint 9 is communicated with the stirring shaft 2. This design enables the water pump 7 to be fixed together with the stirring cylinder body 1 to form an integrated unit, which is more convenient when it is necessary to move the whole set of equipment. Installing the water pump 7 at the top end is also beneficial to simplifying the pipeline layout.

[0037] In a preferred embodiment, the water pump 7 is not fixedly connected to the stirring cylinder body 1, and the water pump 7 can be placed on the ground. The water inlet pipe 8 is set as a flexible pipe. One end of the water inlet pipe 8 is connected to the water pump 7, and the other end of the water inlet pipe 8 is connected to the rotary joint 9. The rotary joint 9 is communicated with the stirring shaft 2. Adopting such a design helps to reduce the weight of the upper structure of the stirring equipment, making the top of the stirring cylinder body 1 easier to disassemble. For example, when it is necessary to clean or maintain the inside of the stirring cylinder body 1, the top 1001 of the cylinder body can be removed more conveniently and quickly.

[0038] The usage steps of the present utility model:

[0039] First, inject the stirring material from the feed inlet 13. Then, start the motor 4. Through the transmission of the first gear 5 and the second gear 6, the stirring shaft 2 can be driven to rotate, thereby driving the stirring rod 3 to rotate to stir the material. After stirring for a certain period of time, turn off the motor 4, and then open the discharge port 14 to send out the material. At this time, there will be residual material in the stirring cylinder 1. Connect the water pump 7 to the water source, and then start the water pump 7. After the water passes through the water inlet pipe 8, it enters the stirring shaft 2 through the rotary joint 9, then reaches the stirring rod 3, and is sprayed out from the nozzles 11 on the spray head 10. Next, start the motor 4. Through the transmission of the first gear 5 and the second gear 6, the stirring shaft 2 can be driven to rotate, thereby driving the spray head 10 on the stirring rod 3 to rotate. In this way, as the spray head 10 rotates in the stirring cylinder 1, the nozzles 11 on both sides of the spray head 10 can wash the inner wall of the stirring cylinder 1, the stirring rod 3, and the stirring shaft 2. It should be noted here that since the water inlet pipe 8 is connected to the stirring shaft 2 through the rotary joint 9, when the stirring shaft 2 rotates, it does not affect the water inlet pipe 8 from injecting water into the stirring shaft 2. Finally, open the discharge port 14 to discharge the flushing material.

[0040] The above is only a preferred embodiment of the present invention, and it does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be able to realize that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
