Description

Technical Field

[0001] The invention relates to the technical field of conductive slurry storage, and more particularly to a conductive slurry storage system. Background Art

[0002] Conductive slurry is a kind of composite slurry. Conductive slurry is made by mixing graphene powder, carbon nanotube powder and liquid. After the graphene powder, carbon nanotube powder and liquid are mixed, they need to be placed in a storage tank for storage.

[0003] At present, the composite slurry on the market is usually directly placed in storage tanks for storage. After the graphene powder and carbon nanotube powder are mixed with the liquid, the composite slurry is transported to the storage tank through a pipeline, and then transported out of the storage tank through the pipeline when needed.

[0004] However, due to the long-term storage of the composite slurry, the graphene powder and carbon nanotube powder in the composite slurry will settle and agglomerate in the storage tank. The sedimentation and agglomeration will cause the coating performance of the composite slurry to deteriorate, resulting in uneven coating during the coating process. Summary of the invention

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] See also Figure 1-8 , the present invention provides the following technical solutions:

[0040] See also Figure 1 A storage system for conductive slurry The storage system for conductive slurry includes a storage tank assembly 2, a fixed base 1 is installed below the storage tank assembly 2, a protective cover 5 is installed above the storage tank assembly 2, a control assembly 3 is installed on the side wall of the storage tank assembly 2, a driving motor 6 is installed on the control assembly 3, two sets of scraping wall assemblies 4 are arranged inside the storage tank assembly 2, and a stirring assembly 7 is arranged in the middle of the storage tank assembly 2.

[0041] See also Figure 2The storage tank assembly 2 is used to provide storage conditions for the composite slurry and provide an installation position for the scraper assembly 4 and the stirring assembly 7. The fixed base 1 provides support for the storage tank assembly 2 and increases the height of the storage tank assembly 2. The control assembly 3 is used to control the drive motor 6. The protective cover 5 is used to prevent impurities in the air from entering the storage tank assembly 2. The drive motor 6 provides power for the stirring assembly 7. The stirring assembly 7 is used to stir the composite slurry. The composite slurry is formed by mixing carbon nanotube powder and graphene powder with liquid to avoid the deposition and agglomeration of carbon nanotubes and graphene with fewer layers at the bottom of the storage tank, thereby weakening the coating effect of the composite slurry. The two sets of scraper assemblies 4 are used to clean the inner wall of the storage tank assembly 2, and clean the agglomerated carbon nanotubes and graphene adhering to the inner wall of the storage tank assembly 2 into the stirring composite slurry to participate in the stirring process of the composite slurry.

[0042] The tank assembly 2 includes a tank top plate 27 , and the tank assembly 2 also includes a tank bottom plate 26 , a fixed base 1 is installed below the tank bottom plate 26 , a tank body 23 is installed above the tank bottom plate 26 , and a tank top plate 27 is installed above the tank body 23 .

[0043] The tank top plate 27 is used to provide support for the scraper assembly 4 and the stirring assembly 7. The tank bottom plate 26 and the tank top plate 27 are closed to the tank body 23. A discharge port is provided at the bottom of the tank bottom plate 26. The fixed base 1 provides support for the tank bottom plate 26.

[0044] A discharge pipe 22 is installed below the tank bottom plate 26 , and a discharge valve 21 is installed at the other end of the discharge pipe 22 . A feed pipe 24 is installed on the side wall of the tank body 23 , and a feed valve 25 is installed at the other end of the feed pipe 24 .

[0045] The discharge pipe 22 is connected to the discharge port on the tank bottom plate 26 , and the composite slurry to be discharged is discharged from the discharge pipe 22 . When discharge is required, the discharge valve 21 is opened, and the composite slurry flows out from the discharge pipe 22 .

[0046] Two arc-shaped grooves 28 are arranged on the top plate 27 of the storage tank, and two sets of wall scraping assemblies 4 are arranged on the two arc-shaped grooves 28 respectively.

[0047] The two arc-shaped grooves 28 are matched with the two sets of wall scraping components 4 to facilitate the wall scraping components 4 to clean the inner wall of the storage tank body 23 .

[0048] The control assembly 3 includes a mounting plate 32 , which is mounted on a side wall of the mounting plate 32 , on which an electric control module 31 is mounted, and a driving slot 33 is also provided on the mounting plate 32 , on which a driving motor 6 is mounted.

[0049] The mounting plate 32 provides an installation position for the electric control module 31 and the drive motor 6. The output end of the drive motor 6 is installed in cooperation with the drive slot 33. The output end of the drive motor 6 penetrates the protective cover 5 and is connected to the drive shaft 71. The electric control module 31 provides an output electrical signal for the drive motor. Since the graphene powder and carbon nanotube powder in the composite slurry will not agglomerate and precipitate in a short time, it is necessary to control the rotation of the drive motor 6 by setting the electric control module 31. The drive motor 6 controls the stirring assembly 7 to stir the composite slurry to avoid the storage time being too long, which may cause the graphene powder and carbon nanotube powder to agglomerate in the composite slurry. Agglomeration and precipitation in the slurry cause the coating performance of the composite slurry to deteriorate. The electronic control module 31 can be set with a timing so that the drive motor 6 stirs the composite slurry at regular intervals (the period of time here is not specifically limited, and the agglomeration and precipitation times vary depending on the storage method of the composite slurry. Therefore, the stirring interval time is set as needed). The electronic control module 31 can adjust the output power of the drive motor 6 to avoid waste of resources. When there are more agglomerates, a high-power drive mode can be output. If there are fewer agglomerates or precipitation, only normal power needs to be output.

[0050] See also Figure 5 The two sets of scraping wall assemblies 4 both include arc-shaped slide rails 41 , which are symmetrically arranged above the tank top plate 27 , and electric sliders 43 are slidably mounted on the two arc-shaped slide rails 41 .

[0051] See also Figure 8 The two arc-shaped slide rails 41 are fitted and installed with the arc-shaped groove 28, and the electric slider 43 can be driven by itself on the arc-shaped slide rail 41. A rack is arranged on the arc-shaped slide rail 41, and a pinion 432, a pulley 433 and a stepper motor 431 are arranged on the electric slider 43. When the stepper motor 431 drives the pinion 432 to rotate, the pinion 432 moves along the rack, and the pulley 433 fits with the arc-shaped slide rail 41 and rotates in coordination, thereby driving the electric slider 43 on the arc-shaped slide rail 41 to move in an arc. The arc-shaped slide rail 41 has a guiding function, which can make the electric slider 43 move to the target position along the curved trajectory of the arc-shaped slide rail 41.

[0052] A plurality of connecting columns 42 are provided below the electric slider 43 , and a scraper mechanism 44 is installed below the plurality of connecting columns 42 . The connecting columns 42 pass through the tank top plate 27 and are installed with the scraper mechanism 44 , and the scraper mechanism 44 is in contact with the inner wall of the tank assembly 2 .

[0053] A plurality of connecting columns 42 can connect the electric slider 43 and the scraper mechanism 44. When the electric slider 43 moves along the curve of the arc-shaped slide rail 41, the scraper mechanism 44 is synchronously driven to move along the arc of the inner wall of the tank body 23 to scrape off the carbon nanotube clusters and graphene powder clusters adhering to the inner wall of the tank body 23.

[0054] The scraper mechanism 44 includes a scraper body 441 . The connecting column 42 is connected to the scraper body 441 . A first scraper 442 and a second scraper 443 are respectively disposed on both sides of the scraper body 441 .

[0055] The scraper body 441 is used to provide an installation environment for the first scraper 442 and the second scraper 443. The scraper body 441 is in contact with the inner wall of the tank body 23, and the first scraper 442 and the second scraper 443 are in contact with the inner wall of the tank body 23. The side that is not in contact with the inner wall of the tank body 23 is provided with an arc, which is convenient for scraping off the carbon nanotube clusters and graphene powder clusters adhering to the inner wall of the tank body 23 and reducing the scraping resistance.

[0056] By setting up multiple connecting columns 42 to connect the electric slider 43 and the scraper mechanism 44, the electric slider 43 drives the scraper mechanism 44 to move in an arc shape along the inner wall of the tank body 23, so as to scrape off the carbon nanotube agglomerates and graphene powder agglomerates adhering to the inner wall of the tank body 23, thereby achieving the effect of scraping off the carbon nanotube agglomerates and graphene powder agglomerates adhering to the inner wall of the tank body 23.

[0057] See also Figure 3 and Figure 4 The stirring assembly 7 includes a driving shaft 71, the output end of the driving motor 6 is connected to the driving shaft 71, a driving tooth 72 is installed at the lower end of the driving shaft 71, two driven teeth 73 are meshed and installed on the side of the driving tooth 72, a stirring shaft 75 is installed in the middle of the two driven teeth 73, and stirring blades 74 are equidistantly arranged on the two stirring shafts 75.

[0058] The driving motor 6 can drive the driving shaft 71 on the control component 3 to rotate and provide power for the driving shaft 71. The driving shaft 71 can drive the driving tooth 72 to rotate. When the driving tooth 72 rotates, it drives the two driven teeth 73 to rotate. When the driven teeth 73 rotate, it can drive the two stirring shafts 75 to rotate. The rotation of the stirring shaft 75 synchronously drives the stirring blades 74 to rotate. When the two groups of stirring blades 74 rotate synchronously, the mixing and flow of the composite slurry can be more effectively promoted. When processing more composite slurries, the uniform mixing of graphene powder and carbon nanotube powder with liquid can be achieved more quickly, and the deposition of graphene powder and carbon nanotube powder can be more effectively prevented.

[0059] By setting a driving motor 6 to drive the driving shaft 71 to rotate, the driving shaft 71 synchronously drives the stirring blades 74 to rotate, and the two sets of stirring blades 74 synchronously stir the composite slurry, thereby preventing the graphene powder and carbon nanotube powder from agglomerating and settling to the bottom of the storage tank.

[0060] The two stirring shafts 75 both penetrate the top plate 27 of the storage tank and are connected to the two driven teeth 73 , and a winding mechanism 76 is installed at the bottom of the two stirring shafts 75 .

[0061] The material rolling mechanism 76 is disposed below the stirring blade 74 , and the material rolling mechanism 76 rotates in close contact with the bottom plate 26 of the storage tank. The material rolling mechanism 76 can scrape up the graphene powder and carbon nanotube powder that are adhered to and deposited on the bottom of the storage tank.

[0062] The two coiling mechanisms 76 each include a coiling body 761 , in which two stirring shafts 75 are respectively installed. Four coiling blades 762 are equidistantly arranged in a circle on the outer wall of the coiling body 761 , and the coiling blades 762 are provided with an arc.

[0063] The coil body 761 is arranged below the stirring blade 74, and the two coil bodies 761 rotate synchronously with the two stirring shafts 75. The four coil blades 762 are in contact with the bottom plate 26 of the storage tank. When the coil body 761 rotates, the four coil blades 762 are driven to rotate. The four coil blades 762 can scrape up the graphene powder and carbon nanotube powder that are stuck and deposited on the bottom plate 26 of the storage tank.

[0064] By installing the coil body 761 under the stirring blade 74, the coil body 761 rotates synchronously with the two stirring shafts 75. During the rotation, the deposited and sticky graphene powder and carbon nanotube powder are rolled up through the curvature of the four coil blades 762 and participate in the stirring process of the stirring blade 74, thereby achieving the effect of adding the graphene powder and carbon nanotube powder deposited and stuck on the bottom plate 26 of the storage tank into the stirring process.

[0065] When the composite slurry needs to be stirred in the storage tank assembly 2, a stirring signal is sent through the electronic control module 31 to drive the motor 6 to rotate, thereby driving the stirring assembly 7 to stir the composite slurry. At this time, the electric slider 43 slides on the arc-shaped slide rail 41, and the scraper mechanism 44 cleans the graphene powder and carbon nanotube powder lumps on the inner wall of the storage tank body 23, and adds them to the stirring process of the stirring assembly 7. At the same time, the winding mechanism 76 rolls up the graphene powder and carbon nanotube powder lumps deposited on the tank bottom plate 26, and adds them to the stirring process of the stirring assembly 7, thereby achieving the effect of involving the graphene powder and carbon nanotube powder lumps on the inner wall of the tank body 23 and the tank bottom plate 26 in the stirring process.
