Description

Technical Field

[0001] The present invention relates to the field of nano - material dispersion equipment, and particularly to a reaction device for preparing graphene composite materials based on dynamic cloth control. Background Art

[0002] Graphene is an allotrope of carbon. Carbon atoms are bonded by sp² hybridization to form a single - layer hexagonal honeycomb lattice of graphene. Using this crystal structure of graphene, fullerenes (C60), graphene quantum dots, carbon nanotubes, nanoribbons, multi - walled carbon nanotubes, and nano - horns can be constructed. Stacked graphene 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] Graphene composite materials are multifunctional materials formed by combining graphene (a two - dimensional material composed of a single layer of carbon atoms) with other materials (such as polymers, metals, ceramics, or carbon - based materials, etc.). By complementing the excellent properties of graphene (such as high conductivity, high strength, high thermal conductivity, flexibility, etc.) with the properties of the matrix material, the comprehensive performance of the composite material can be significantly improved.

[0004] In the prior art, there are many production processes for graphene composite materials. Among them, the relatively common solution mixing method is to disperse graphene raw materials in a solvent using a reaction device, mix them with a matrix material (such as polymers, metals, ceramics, or carbon - based materials, etc.), and then form a composite material through evaporation, reduction, or curing. Most of the existing reaction devices directly sprinkle and disperse graphene raw materials into the solvent, or simply spray and disperse graphene raw materials in the reaction device using a sprayer. Such a dispersion method is mostly not uniform enough, resulting in non - uniform fusion of graphene raw materials and matrix materials in the subsequent reaction device, or the need for long - time stirring to complete the operation requirement of uniform fusion. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a reaction device for preparing graphene composite materials based on dynamic cloth control, which has uniform cloth feeding to ensure that graphene raw materials can fully fuse with the matrix material, aiming at the deficiencies of the prior art presented in the background art.

[0006] The present invention is achieved through the following technical solutions: It includes a reaction chamber, a stirring shaft rotatably connected in the reaction chamber, and a stirring rod connected to the stirring shaft; a rotating carrier plate rotatably connected is arranged in the reaction chamber, and a driving device for driving the rotating carrier plate; a connecting rod structure is formed inside the rotating carrier plate, and a plurality of cloth feeders are slidably connected to the connecting rod: The distributor is of a columnar structure, with a storage cavity formed inside it. An inlet is provided at the upper end of the storage cavity, and an outlet is provided at the lower end. A spraying chamber is arranged below the outlet. Among them, a discharge valve is movably connected inside the outlet.

[0007] By adopting the above technical solution, the distributor can drive the air flow to flow through the spraying chamber under the action of the internal fan. At the same time, the graphene raw material in the storage cavity inside the distributor slides into the spraying chamber in small amounts and at a uniform speed under the action of the discharge valve, and is blown out of the distributor under the action of the air flow, completing the operation requirement of evenly distributing materials in the reaction chamber. In addition, the distributor can rotate and displace under the drive of the rotating carrier plate and can slide along the connecting rod, so as to realize the comprehensive and uniform material distribution operation in the reaction chamber.

The rotating carrier plate is rotatably connected to the bearing cavity through a plain bearing. A tooth groove is formed on the outer side wall of the rotating carrier plate. The driving device includes a driving motor fixedly installed on one side of the upper end of the reaction chamber. The transmission output end of the driving motor is connected with a transmission gear, and the transmission gear meshes with the outer side wall of the rotating carrier plate.

Its driving device consists of a polygonal abutting tooth on the stirring shaft, a V-shaped abutting seat movably arranged inside the inner ring seat, and a threaded telescopic rod. Among them, the V-shaped abutting seat corresponds to the peripheral corners of the polygonal structure of the abutting tooth. One end face of the abutting seat facing away from the abutting tooth is fixedly connected to the movable end of the threaded telescopic rod, and the fixed end of the threaded telescopic rod is fixedly installed on the inner side wall of the inner ring seat.

[0012] In a specific technical solution, a linear slide rail structure is provided inside the connecting rod. The upper end of the distributor has a mounting seat.

[0014] In a specific technical solution, the spraying chamber, the air inlet net and the spraying net all adopt an elastic connection structure, and vibrating rods are respectively installed above the air inlet net and the spraying net. The actuating ends of the vibrating rods are respectively connected to the two net surfaces, and high-frequency tremors are generated through the elastic cooperation of the springs.

[0015] By adopting the above technical solution, the air inlet net and the spraying net connected by springs can generate tremor movements under the action of the vibrating rods, so that the graphene raw material particles attached to their net surfaces can be separated, effectively removing the graphene particles attached to the net surfaces and avoiding airway blockage and affecting the discharging operation effect of the cloth distributor.

[0016] In a specific technical solution, the blanking valve includes a valve body for blocking the blanking port and a driving rod for driving the displacement of the valve body, and the valve body is fixedly installed at the movable end of the driving rod.

[0017] By adopting the above technical solution, the valve body can be displaced and adjusted in the blanking port under the action of the driving rod, so as to control the opening size of the blanking port. Therefore, the passing amount of graphene raw materials at the blanking port can be controlled, and the passing amount of graphene raw materials is controlled by changing the flow cross-sectional area, thereby adjusting the cloth speed and optimizing the cloth uniformity.

[0020] In a specific technical solution, a first feed valve is arranged on one side of the upper end of the reaction chamber, a second feed valve is arranged on the other side of the upper end of the reaction chamber, and a discharge valve is arranged at the bottom end.

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] As Figure 1 、 Figures 3 - 6 shown, a reaction device for preparing graphene composite materials based on dynamic cloth control in this embodiment includes a reaction chamber 1, a stirring shaft 201 rotatably connected in the reaction chamber 1, and a stirring rod 202 connected to the stirring shaft 201; characterized in that: a rotatably connected rotating carrier disk 301 and a driving device for driving the rotating carrier disk 301 are arranged in the reaction chamber 1; a connecting rod 302 structure is formed inside the rotating carrier disk 301, and a plurality of cloth distributors 303 are slidably connected to the connecting rod 302; The distributor 303 is of a columnar structure, with a material storage chamber 303-2 formed inside it. An inlet 303-1 is provided at the upper end of the material storage chamber 303-2, and a discharge port 303-3 is provided at the lower end. A spraying chamber 303-6 is provided below the discharge port 303-3. Among them, a discharge valve 303-4 is movably connected inside the discharge port 303-3. The spraying chamber 303-6 is a through chamber, with a fan 303-7 installed inside it, an air inlet net 303-8 installed at its air inlet end, and a spraying net 303-9 installed at its air discharge end; By providing a reaction device for preparing graphene composites with a uniform cloth-feeding function in the embodiment of the present invention, it is ensured that the graphene raw material can be fully fused with the matrix material, solving the problem in the prior art that the reaction device usually directly scatters the graphene raw material or simply disperses it into the solvent through a sprayer. Such methods are likely to cause uneven distribution of raw materials in the reaction chamber, and then the fusion effect of graphene and the matrix material is not ideal, and it is necessary to rely on long-term stirring to meet the uniformity requirements, or simply spray and disperse the graphene raw material into the solvent by a sprayer. Such a dispersion method is mostly not uniform enough, resulting in uneven fusion of the graphene raw material and the matrix material in the subsequent reaction device, or the need for long-term stirring to complete the uniform fusion operation requirements. The core improvement of this embodiment lies in: configuring a plurality of rotatable and position-adjustable distributors 303 in the reaction chamber 1 for precise addition of graphene raw materials during the production process of the composite material. During operation, the distributor 303 can slide along the connecting rod 302 to cover the cloth-feeding requirements of different regions in the reactor; at the same time, by regulating the rotation speeds of the rotating carrier 301 and the distributor 303, a dynamic cloth-feeding mode of rotating while displacing is realized, and finally the uniformity of cloth-feeding during the production process of the graphene composite material is ensured.

[0031] Among them, the graphene raw material can enter the distributor 303 through the inlet 303-1 and be stored in the material storage chamber 303-2. During the cloth-feeding operation, the discharge valve 303-4 opens a small gap, so that the graphene raw material located in the material storage chamber 303-2 can slide into the spraying chamber 303-6 in a small amount at a certain speed. At this time, the fan 303-7 can drive the air flow in the spraying chamber 303-6, and use the air flow to blow the sliding graphene raw material, so that the graphene raw material can be continuously sprayed into the reaction chamber 1 at a certain speed. Combining with the rotational displacement movement of the above-mentioned distributor 303, the overall cloth-feeding operation effect can be achieved.

[0032] In a specific embodiment, such as Figure 1 and Figure 2As shown in the figure, a first feed valve 101 is provided on one side of the upper end of the reaction chamber 1, a second feed valve 105 is provided on the other side of the upper end of the reaction chamber 1, and a discharge valve 102 is provided at the bottom end of one side wall of the reaction chamber 1. Among them, the first feed valve 101 is used to inject the matrix material into the reaction chamber 1, the second feed valve 105 is used to inject the graphene raw material into the feeder 303, and the discharge valve 102 is used to discharge the uniformly fused graphene composite material from the reaction chamber 1.

[0033] In the above embodiment, as Figure 10 and Figure 11 shown, a feeder 7 is arranged at the second feed valve 105 of the reaction chamber 1. A plurality of material loading grooves 701 are formed in the feeder 7, and an electric control valve 702 is installed at the bottom of the material loading groove 701. The lower end of the feeder 7 is formed with a socket 703 for plugging into the second feed valve 105, and the lower end opening of the socket 703 is adapted to the inlet 303-1 of the feeder 303. The feeder 7 can simultaneously load a plurality of certain amounts of graphene raw materials through the plurality of material loading grooves 701 and be plugged into the second feed valve 105 through the socket 703. When the feeder 303 moves to directly below the feeder 7, one of the electric control valves 702 can be opened, so that the graphene raw material loaded in one of the material loading grooves 701 can slide into the inlet 303-1 of the feeder 303 through the socket 703 and enter the storage cavity 303-2.

[0034] In a specific embodiment, as Figures 1 - 3 shown, the stirring rod 202 is fixedly installed on the outer peripheral wall of the bottom end of the stirring shaft 201. A stirring motor 2 is installed at the center of the top of the reaction chamber 1. The stirring shaft 201 is directly connected to the motor output end through a coupling. The stirring motor 2 can drive the stirring shaft 201 and the stirring rod 202 to perform rotational motion, so as to realize the mixing operation of the matrix material and the graphene raw material in the reaction chamber 1.

[0035] In a specific embodiment, as Figures 2 - 4As shown in the figure, a bearing cavity 103 is formed at the top inside the reaction chamber 1. The rotating carrier disk 301 is rotatably connected to the bearing cavity 103 through a plain bearing. Tooth grooves are formed on the outer side wall of the rotating carrier disk 301. The driving device includes a driving motor 4 fixedly installed on one side of the upper end of the reaction chamber 1. The transmission output end of the driving motor 4 is connected with a transmission gear 401. A driving cavity 104 for the transmission gear 401 to rotate and move is formed on one side of the bearing cavity 103 in the reaction chamber 1. The transmission gear 401 meshes with the tooth grooves on the outer side wall of the rotating carrier disk 301 in the driving cavity 104. In this embodiment, the driving motor 4 can drive the transmission gear 401 to rotate in the driving cavity 104, and drive the rotating carrier disk 301 to rotate along the bearing cavity 103 through its meshing relationship with the tooth grooves on the outer side wall of the rotating carrier disk 301, so as to ensure that the rotating carrier disk 301 can carry the cloth distributor 303 to make flexible rotational displacement in the reaction chamber 1.

[0036] In a specific embodiment, as Figure 2 、 Figure 8 and Figure 9 shown in the figure, a bearing cavity 103 is formed at the top inside the reaction chamber 1. The rotating carrier disk 301 is rotatably connected to the bearing cavity 103 through a plain bearing. An inner ring seat 5 is formed at the central part of the connecting rod 302 on the rotating carrier disk 301. The driving device is a abutting tooth 601 formed on the stirring shaft 201, an abutting seat 602 movably connected to the inner ring seat 5, and a threaded telescopic rod 603 for driving the displacement of the abutting seat 602. Among them, the abutting tooth 601 is of a polygonal structure, the abutting seat 602 is of a V-shaped structure, and corresponds to the peripheral corners of the polygonal structure of the abutting tooth 601. One end face of the abutting seat 602 facing away from the abutting tooth 601 is fixedly connected to the movable end of the threaded telescopic rod 603. The fixed end of the threaded telescopic rod 603 is fixedly installed on the inner side wall of the inner ring seat 5. In this embodiment, the abutting tooth 601 can rotate synchronously with the stirring shaft 201. When the stirring shaft 201 is stationary, the threaded telescopic rod 603 can be controlled to extend, driving the abutting seat 602 to cover the peripheral corners of the polygonal structure of the abutting tooth 601, so as to force the abutting seat 602 to establish a transmission effect with the abutting tooth 601. Then, the stirring shaft 201 rotates driven by the stirring motor 2, and transmits its rotational power to the inner ring seat 5 and the rotating carrier disk 301 through the abutting tooth 601 and the abutting seat 602, so that the rotating carrier disk 301 can complete the rotational movement by means of the power of the stirring motor 2, thus saving power sources. The threaded telescopic rod 603 is driven in the form of an electric push rod. The internal threaded rod is driven by a micro motor to rotate, and then its sliding displacement along the inner stroke cavity of the fixed rod is forced by the meshing connection relationship of its movable rod.

[0037] In the above two embodiments, the plain bearing can ensure the smooth and stable rotational movement of the rotating carrier disk 301 along the bearing cavity 103.

[0038] In a specific embodiment, as Figure 3 , Figure 4 , Figure 8 and Figure 9 shown, a slide rail cavity 305 is formed on the connecting rod 302. A mounting seat 304 is formed at the upper end of the distributor 303. A driving wheel 306 is rotatably connected to the lower end surface of the mounting seat 304. The mounting seat 304 is slidably connected along the slide rail cavity 305 through the driving wheel 306. The feeding port 303-1 is opened in the middle of the upper end of the mounting seat 304 and communicates with the storage cavity 303-2. The distributor 303 can perform a sliding displacement movement along the slide rail cavity 305 under the action of the driving wheel 306, so as to cooperate with the rotational movement of the rotating turntable 301 to perform a more comprehensive and uniform distribution operation in the reaction chamber 1.

[0039] In a specific embodiment, as Figure 7 shown, the spraying chamber 303-6 is connected to the air inlet net 303-8 and the spraying net 303-9 through springs respectively. The vibrating rods 303-11 are fixedly installed above the air inlet net 303-8 and the spraying net 303-9 in the spraying chamber 303-6. The acting ends of the vibrating rods 303-11 are connected to the two net surfaces respectively. High-frequency vibrations are generated through the elastic cooperation of the springs. In this embodiment, the air inlet net 303-8 and the spraying net 303-9 connected by the springs are in a movable state. The vibrating rods 303-11 can drive the air inlet net 303-8 and the spraying net 303-9 to vibrate, so that the graphene raw materials attached to their surfaces can be separated from their net surfaces, avoiding blockage of the air duct.

[0040] In a specific embodiment, as Figure 5 and Figure 6 shown, the blanking valve 303-4 includes a valve body for blocking the blanking port 303-3 and a driving rod 303-5 for driving the displacement of the valve body. The valve body is fixedly installed at the movable end of the driving rod 303-5. The driving rod 303-5 can drive the valve body to displace in the blanking port 303-3 through an extending movement, so as to control the opening and closing degree of the valve body in the blanking port 303-3, thereby controlling the passing amount of the graphene raw materials at the blanking port 303-3 and cooperating with the airflow generated by the fan 303-7 to achieve a continuous and small amount of atomized spraying effect.

[0041] In addition, in this embodiment, the structure of the blanking valve 303-4 can be replaced by other valve bodies, such as a butterfly valve or a gate valve.
