Graphene, with its unique physical and chemical properties, has demonstrated great potential in the field of catalysis. In the production process of graphene materials, excellent dispersion effect is the key link to ensure its performance and quality. If graphene cannot be evenly dispersed, it is very likely to affect its catalytic effect and stability in subsequent applications. The demand for catalytic degradation of formaldehyde under dim light conditions sets higher standards for the performance and preparation methods of graphene materials. Developing exclusive dispersion devices and optimizing production methods are conducive to improving the quality and production efficiency of graphene materials and meeting their application demands in the field of environmental protection.

[0022] Reference Figure 1 to Figure 6 An embodiment of the present invention proposes a dispersion device for producing graphene materials for micro-photocatalytic degradation of formaldehyde, including a frame 1, a sanding barrel 2 arranged on the frame 1, the interior of the sanding barrel 2 has a dispersion space 201, the dispersion space 201 has a dispersion inlet 202 and a dispersion outlet 203, a stirring member 3 is rotatably arranged in the dispersion space 201, a sliding plate 4 is slidably and rotatably arranged on the inner wall of the dispersion space 201, is located at one end of the stirring member 3, and shrinks or enlarges the dispersion space 201 after sliding.

[0023] In this embodiment, in the dispersion device for producing graphene materials for micro-photocatalytic degradation of formaldehyde, a frame 1 is included as an integral support structure. The sand mill 2 is mounted on the frame 1, and the dispersion space 201 inside it is used for grinding and dispersing graphene particles in a solvent. The dispersion space 201 is provided with a dispersion inlet 202 for inputting a mixture of graphene particles and solvent, and a dispersion outlet 203 for outputting the materials after grinding and dispersion. The stirring member 3 is rotatably mounted in the dispersion space 201, and the dispersion space 201 is filled with grinding sand. The sliding plate 4 is slidably and rotatably arranged on the inner wall of the dispersion space 201, and is located at one end of the stirring member 3. During operation, the mixture of graphene particles and solvent enters the dispersion space 201 from the dispersion inlet 202. The stirring member 3 starts to rotate, pushing the grinding sand in the dispersion space 201 to move, and the grinding sand grinds and disperses the graphene particles. According to the specific needs in the processing process, the sliding plate 4 slides and rotates on the inner wall of the dispersion space 201 to reduce or increase the dispersion space 201. When the dispersion space 201 is reduced, the contact between the grinding sand and the graphene particles is closer, and the grinding and dispersion force is enhanced; when the dispersion space 201 is increased, the preliminarily dispersed materials can be further mixed evenly. The specific judgment point of the size of the dispersion space 201 is that the materials in the sand mill barrel 2 are gradually separated and discharged from the fine materials that meet the standards and the coarse materials that do not meet the standards, and then the coarse materials are recycled back for reprocessing, and the size of the dispersion space 201 is adjusted by the total amount of the coarse materials and the corresponding part of the solvent, so that it always maintains a good grinding effect. The design of the sliding plate 4 allows the dispersion space 201 to be flexibly adjusted, and can accurately control the grinding and dispersion conditions according to the initial state of the graphene particles and the progress of grinding and dispersion, thereby improving the grinding efficiency and dispersion quality. The stirring member 3 pushes the grinding sand to grind and disperse the graphene particles, ensuring the uniform dispersion of the graphene particles in the solvent. This structural design makes the grinding and dispersion process of the graphene particles in the solvent inside the sand mill more controllable and efficient, and improves the production quality and efficiency of the graphene material. Compared with traditional sand mills, it can more effectively cope with the special needs of grinding and dispersing graphene particles in solvents, and reduce the problem of unstable production quality caused by uncontrollable dispersion conditions. Furthermore, it includes that there are a plurality of stirring blades 5 which are circumferentially arranged on the stirring element 3 , and the circumferentially arranged stirring elements 3 form a group, and a plurality of groups of stirring blades 5 are linearly arranged on the stirring element 3 along the rotation axis of the stirring element 3 .

[0024] In this embodiment, when the stirring member 3 rotates, the multiple groups of stirring blades 5 on the stirring member 3 work simultaneously. The circumferentially arranged stirring blades 5 stir the mixture of graphene particles, solvent and abrasive sand in the dispersion space 201 to make them fully contact and mix. The multiple groups of stirring blades 5 linearly arranged along the rotation axis of the stirring member 3 can play a role at different axial positions to ensure that the materials in the entire dispersion space 201 can be evenly stirred and ground. The design of multiple groups of stirring blades 5 greatly enhances the stirring effect, making the dispersion of graphene particles in the solvent more uniform and efficient. The stirring blades 5 at different positions work together to effectively avoid the problem of uneven dispersion and improve the quality and consistency of the product. This design optimizes the function of the stirring member 3 and further improves the working efficiency and dispersion quality of the entire dispersion device.

[0025] Furthermore, the stirring member 3 is cylindrical, and the stirring member 3 also has a sliding shell portion 301, the sliding shell portion 301 has a first guide groove 302, the first guide groove 302 is along the radial direction of the stirring member 3, there are several sliding shell portions 301, which are arranged circumferentially on the stirring member 3, and also include a telescopic blade 6 slidingly arranged in the first guide groove 302, which extends out or enters the first guide groove 302 after sliding, and one end of the first elastic member 7 is arranged at the bottom of the first guide groove 302, and the other end is arranged at the bottom of the telescopic blade 6, providing a force for the telescopic blade 6 to slide toward the bottom of the first guide groove 302.

[0026] In this embodiment, during the rotation of the stirring member 3, when the centrifugal force is greater than the elastic force of the first elastic member 7, the telescopic blade 6 overcomes the elastic force of the first elastic member 7 and slides outward along the first guide groove 302; when the centrifugal force decreases, the elastic force of the first elastic member 7 causes the telescopic blade 6 to slide into the bottom of the first guide groove 302. This retractable blade design can automatically adjust the telescopic state according to the rotation speed of the stirring member 3. It extends at a high speed to expand the range of stirring and grinding and improve the dispersion efficiency; it shrinks at a low speed to save space and reduce resistance. The setting of the first elastic member 7 ensures the stability and reliability of the telescopic blade 6. Through this adaptive telescopic design, the stirring and grinding effects are further optimized, and the dispersion quality and production efficiency of the graphene material in the solvent are improved.

[0027] Furthermore, a plurality of circumferentially arranged sliding shell portions 301 , the first elastic member 7 and the telescopic blades 6 form a group of blade assemblies 610 . The plurality of groups of blade assemblies 610 are axially arranged on the stirring member 3 , and the stirring blades 5 and the blade assemblies 610 are arranged at intervals.

[0028] In this embodiment, when the stirring member 3 rotates, as the rotation speed changes, the telescopic blade 6 is extended and retracted under the action of centrifugal force and the first elastic member 7. The blade assemblies 610 and the stirring blades 5 at different axial positions work together to stir and grind the mixture of graphene particles, solvent and abrasive sand at different positions in the dispersion space 201. The axial multiple groups of the blade assemblies 610 and the spaced arrangement with the stirring blades 5 make the stirring and grinding effects more uniform and comprehensive in the axial and circumferential directions of the stirring member 3. It can adapt to materials in different positions and states and improve the overall dispersion effect and efficiency. This design optimizes the material processing capacity of the stirring member 3, ensures the high-quality dispersion of the graphene material in the solvent, and improves the stability and consistency of the production process.

[0029] Furthermore, a main grinding space 303 is formed between the stirring element 3 and the inner wall of the sand mill 2, a recovery space 304 is provided inside the stirring element 3, the stirring element 3 has a liquid passage 305, both ends of the liquid passage 305 are respectively connected to the main grinding space 303 and the recovery space 304, the dispersion inlet 202 leads to the main grinding space 303, the recovery space 304 leads to the dispersion outlet 203, and also includes a centrifugal separation element 8 arranged in the recovery space 304, and one end of the centrifugal separation element 8 is connected to the dispersion outlet 203.

[0030] In this embodiment, during the grinding and dispersing process, the material is fully ground in the main grinding space 303. The ground mixed liquid enters the recovery space 304 through the liquid passage 305. In the recovery space 304, the centrifugal separation element 8 starts to work and separates the mixed liquid under the action of centrifugal force. The liquid that meets the requirements flows to the dispersion outlet 203 through one end of the centrifugal separation element 8 and is discharged. During the grinding and dispersing process, the material is fully ground in the main grinding space 303. The ground mixed liquid enters the recovery space 304 through the liquid passage 305, and the centrifugal separation element 8 separates the mixed liquid, and the fine material that meets the standard and the coarse material that does not meet the standard are discharged from the recovery space 304. Among them, a part of the coarse material that does not meet the standard is returned to the main grinding space 303 for reprocessing. According to the return amount of the coarse material that does not meet the standard and the total amount of the corresponding part of the solvent, the sliding plate 4 slides and rotates on the inner wall of the dispersion space 201 to adjust the size of the dispersion space 201. After the dispersion space 201 is adjusted, the material is ground again so that the material always maintains a good grinding effect. The size of the dispersion space 201 can be flexibly adjusted by the sliding plate 4, and the grinding conditions can be optimized according to factors such as the amount of coarse materials that do not meet the standards, so as to ensure that a good grinding effect is always maintained and the product quality is stabilized. The centrifugal separation element 8 discharges both the fine materials that meet the standards and the coarse materials that do not meet the standards in a timely manner, realizing efficient material separation and recycling, improving production efficiency, reducing ineffective processing, and reducing production costs.

[0031] Furthermore, the stirring member 3 has a second guide groove 307 along the axial direction, and also includes a telescopic sliding section 9 slidably arranged in the second guide groove 307. One end of the second elastic member 10 is arranged on the bottom wall of the second guide groove 307, and the other end is arranged on the telescopic sliding section 9, providing a force to move the telescopic sliding section 9 away from the bottom wall of the second guide groove 307.

[0032] In this embodiment, when the sliding plate 4 slides to reduce the dispersion space 201, the distance between each stirring member 3 is compressed. At this time, the telescopic sliding section 9 slides along the second guide groove 307 toward the bottom wall under pressure, compressing the second elastic member 10. In this compressed state, the layout between the stirring members 3 is tighter, and more efficient stirring and grinding actions can be maintained in a limited space to ensure that the materials are fully processed. The design of the telescopic sliding section 9 enables the stirring members 3 to automatically adjust their layout when the dispersion space 201 is reduced, adapt to spatial changes, and maintain an efficient working state. This helps to ensure a good grinding and dispersion effect even when the space is limited, improves the flexibility and adaptability of the equipment, and ensures the stability and efficiency of the graphene material production process.

[0033] Furthermore, it also includes a liquid collecting part 11 arranged on one side of the frame 1, the liquid collecting part 11 has a liquid collecting chamber 1101, and a sliding partition 12 is horizontally slidably arranged in the liquid collecting chamber 1101, and divides the liquid collecting chamber 1101 into a first liquid collecting chamber 1102 and a second liquid collecting chamber 1103 distributed on the left and right, the first liquid collecting chamber 1102 leads to the dispersion inlet 202, and the dispersion outlet 203 leads to the second liquid collecting chamber 1103.

[0034] In this embodiment, during operation, the mixed liquid that does not meet the standards is first stored in the first liquid collecting chamber 1102, and then enters the dispersion device through the dispersion inlet 202 for processing. The mixed liquid that meets the standards after processing is discharged from the dispersion outlet 203 to the second liquid collecting chamber 1103. The sliding partition 12 will be automatically pushed to slide according to the amount of liquid in the first liquid collecting chamber 1102 and the second liquid collecting chamber 1103. When there is a large amount of mixed liquid that does not meet the standards in the first liquid collecting chamber 1102, the sliding partition 12 will be pushed to slide in the direction of the second liquid collecting chamber 1103 to make more storage space for the mixed liquid that does not meet the standards; when there is a large amount of mixed liquid that meets the standards in the second liquid collecting chamber 1103, the sliding partition 12 will be pushed to slide in the direction of the first liquid collecting chamber 1102 to provide more storage space for the mixed liquid that meets the standards. The first liquid collecting chamber 1102 is specifically used to store mixed liquid that does not meet the standards, so that the liquid classification is clearer and is conducive to subsequent processing. The sliding partition 12 slides automatically according to the amount of liquid, realizing the flexible allocation of the space of the liquid collecting chamber 1101, ensuring the storage and flow balance of the liquid, and improving the adaptive ability and operation stability of the equipment. This design effectively improves the working efficiency and processing effect of the entire dispersion device, and reduces the possibility of manual intervention and operational errors.

[0035] Further, the stirring member 3 has a main shaft 306, which is rotatably arranged on the frame 1, and the sliding spacer 12 has an extension portion 1201, and also includes a first speed bevel wheel 13 and a second speed bevel wheel. The first speed bevel wheel 13 and the second speed bevel wheel are both rotatably arranged on the frame 1, and the first speed bevel wheel 13 and the second speed bevel wheel are symmetrical and vertically staggered. The first speed bevel wheel 13 is transmission-connected to the output end of the rotating driving member 14, and the second speed bevel wheel is transmission-connected to the main shaft 306. The transmission belt 15 is transmission-connected on the first speed bevel wheel 13 and the second speed bevel wheel, and the transmission belt 15 slides horizontally on the surfaces of the first speed bevel wheel 13 and the second speed bevel wheel, and the extension portion 1201 abuts against the transmission belt 15, and the extension portion 1201 slides and drives the transmission belt 15 to slide horizontally.

[0036] In this embodiment, the rotating driving member 14 works to drive the first speed-changing cone wheel 13 to rotate, and drives the second speed-changing cone wheel to rotate through the transmission belt 15, so that the main shaft 306 rotates to realize the stirring action of the stirring member 3. When the extension 1201 of the sliding partition 12 slides, it will drive the transmission belt 15 to slide horizontally. Since the first speed-changing cone wheel 13 and the second speed-changing cone wheel are symmetrical and vertically misaligned, the horizontal sliding of the transmission belt 15 will change its contact position on the two cone wheels, thereby changing the transmission ratio, and then adjusting the rotation speed of the stirring member 3. Through such a transmission structure, flexible adjustment of the rotation speed of the stirring member 3 is achieved. The sliding of the sliding partition 12 is associated with the speed adjustment of the stirring member 3, and can automatically adjust the working state of the stirring member 3 according to the change of the amount of liquid in the liquid collecting chamber 1101, thereby improving the intelligence and automation of the equipment. This design optimizes the performance of the dispersion device, enabling it to more efficiently process different amounts of materials, ensuring the quality and production efficiency of the product.

[0037] Furthermore, it also includes a sleeve shaft 16 threadedly connected to the frame 1, the sleeve shaft 16 is sleeved outside the main shaft 306, and one end of the sleeve shaft 16 is rotatably set on the sliding plate 4, and after the sleeve shaft 16 rotates, it drives the sliding plate 4 to slide horizontally, thereby expanding or shrinking the dispersion space 201, the transmission shaft 17 is rotatably set on the frame 1, and the transmission shaft 17 is transmission-connected to the main shaft 306, the sliding shaft 18 is set on the extension part 1201, and is horizontally slidably set on the transmission shaft 17, and rotates synchronously with the transmission shaft 17, the first gear 19 is set on the sleeve shaft 16, and the second gear 20 is set on the sliding shaft 18, after the sliding shaft 18 drives the second gear 20 to slide on the transmission shaft 17, the first gear 19 is engaged or disengaged with the second gear 20.

[0038] In this embodiment, as the amount of liquid in the first liquid collecting chamber 1102 and the second liquid collecting chamber 1103 changes, the extension 1201 of the sliding partition 12 will slide accordingly. Since the sliding shaft 18 is arranged on the extension 1201, the sliding of the extension 1201 will drive the sliding shaft 18 to slide horizontally on the transmission shaft 17. When the amount of liquid reaches a certain level and the dispersion space 201 needs to be adjusted, the sliding shaft 18 slides to make the second gear 20 mesh with the first gear 19. The rotation of the transmission shaft 17 drives the sleeve shaft 16 to rotate through the gear transmission belt 15. Since the sleeve shaft 16 is threadedly connected to the frame 1, its rotation will drive the sliding plate 4 to slide horizontally, thereby expanding or reducing the dispersion space 201. If the amount of liquid does not reach the level that needs to be adjusted, the sliding shaft 18 slides to keep the second gear 20 and the first gear 19 out of meshing. This design realizes the function of passively adjusting the size of the dispersion space 201 according to the amount of liquid in the liquid collecting chamber 1101. Without manual intervention, the device can automatically adjust according to the actual situation in the production process, ensuring the stability and efficiency of graphene material production. It improves the adaptive ability of the equipment, reduces the complexity of operation, and helps to improve product quality and production efficiency.
