Description

Technical Field

[0001] This utility model relates to a premixing bucket for preventing splashing of carbon nanotube conductive slurry. Background Technology

[0002] Carbon nanotube conductive slurry, as a high-performance conductive material, is widely used in lithium-ion batteries, supercapacitors, conductive coatings, and other fields. Its preparation process typically involves a premixing stage, where carbon nanotubes are initially mixed with solvents, dispersants, and other components in a high-intensity stirring tank to ensure the uniformity and stability of subsequent dispersion processing. However, this premixing process has a significant technical bottleneck: during the high-speed feeding stage, materials (especially powdered carbon nanotubes or high-viscosity slurries) are prone to splashing due to impact, causing not only material loss (such as the escape of carbon nanotube powder or splashing of liquid slurry) but also environmental pollution (such as dust pollution or chemical solvent leakage), and increased health risks to operators (such as inhalation of dust or exposure to harmful chemicals). Therefore, this invention proposes an anti-splatter premixing tank for carbon nanotube conductive slurry to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a carbon nanotube conductive slurry anti-splashing premixing bucket to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A carbon nanotube conductive slurry anti-splashing premixing tank includes a support frame, on which a stirring tank body is provided;

[0006] A supporting annular plate is provided at the port of the mixing tank. A fixed plate is provided on the supporting annular plate. A sealing circular plate is rotatably provided in the fixed plate. A feeding notch is provided on the sealing circular plate. The feeding notch coincides with the position of the fixed plate. The sealing circular plate rotates about the axis of the supporting annular plate so that the feeding notch does not coincide with the fixed plate.

[0007] As an improvement to the above technical solution, a movable gap is provided between the fixed plate and the supporting annular plate, and the sealing circular plate is adapted to the movable gap and is disposed in the movable gap.

[0008] As an improvement to the above technical solution, an arc-shaped guide groove is provided on the fixing plate;

[0009] A guide ring is provided on the sealing circular plate. The guide ring is matched in position and size with the arc-shaped guide groove. The guide ring is rotatably disposed in the arc-shaped guide groove, so that the sealing circular plate is rotatably disposed in the movable gap.

[0010] As an improvement to the above technical solution, two sets of positioning plates are provided on both sides of the fixing plate, and positioning grooves are provided on the fixing plate. The two sets of positioning grooves are symmetrically arranged, and the sealing circular plate cooperates with the positioning grooves.

[0011] As an improvement to the above technical solution, the sealing circular plate is provided with two sets of positioning rods, and the two sets of positioning rods are respectively arranged on both sides of the fixed plate;

[0012] The sealing disc rotates around the axis supporting the annular plate, causing the positioning rod to enter the positioning groove to position and limit the sealing disc.

[0013] As an improvement to the above technical solution, a fixing block is provided in the positioning groove, and two sets of slopes are symmetrically arranged on the fixing block.

[0014] As an improvement to the above technical solution, the length of the feeding notch cross-section is less than the length of the fixed plate cross-section, and the width of the feeding notch cross-section is less than the width of the fixed plate cross-section.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] During the feeding process, the rotating sealing plate prevents the feeding notch from coinciding with the fixed plate, forming a feeding channel. After feeding is completed, the rotating sealing plate makes the feeding notch coincide with the fixed plate, achieving a complete seal of the tank. This design effectively prevents splashing of materials (such as carbon nanotube conductive slurry) when they are fed into the mixing tank at high speed, reducing material loss and avoiding environmental pollution.

[0017] This structure simplifies the feeding process, allowing for quick switching between feeding and mixing states without the need for additional sealing devices, thus improving production efficiency. At the same time, by preventing dust or liquid splashes, it reduces health risks for operators and workplace safety hazards.

[0018] During the premixing stage of carbon nanotube conductive slurry, this anti-splashing mechanism ensures the uniformity and integrity of material input, reduces the intrusion of external impurities, and thus improves the quality of subsequent mixing and product consistency.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] like Figure 1-6 As shown, this embodiment proposes a carbon nanotube conductive slurry anti-splashing premixing tank, including a support frame 10, on which a stirring tank body 20 is provided;

[0029] A supporting annular plate 21 is provided at the port of the mixing tank 20. A fixing plate 30 is provided on the supporting annular plate 21. A sealing circular plate 40 is rotatably provided in the fixing plate 30. A feeding notch 41 is provided on the sealing circular plate 40. The feeding notch 41 coincides with the position of the fixing plate 30. The sealing circular plate 40 rotates about the axis of the supporting annular plate 21, so that the feeding notch 41 does not coincide with the fixing plate 30.

[0030] In this embodiment, during the production of carbon nanotube conductive slurry, the sealing circular plate 40 is rotated around the axis of the supporting ring plate 21 so that the feeding notch 41 does not coincide with the fixed plate 30. Then, the material is fed into the mixing tank 20 through the feeding notch 41. After the material is completely fed in, the sealing circular plate 40 is rotated around the axis of the supporting ring plate 21 again so that the feeding notch 41 coincides with the fixed plate 30, that is, the feeding notch 41 is located below the fixed plate 30, thus completing the anti-splashing process. After that, the mixing tank 20 can be used to mix the material.

[0031] During the feeding process, the rotating sealing disc 40 prevents the feeding notch 41 from coinciding with the fixed plate 30, thus forming a feeding channel. After feeding is completed, the rotating sealing disc 40 makes the feeding notch 41 coincide with the fixed plate 30, achieving a complete seal of the barrel. This design effectively prevents the splashing of materials (such as carbon nanotube conductive slurry) when they are fed into the mixing barrel 20 at high speed, reducing material loss and avoiding environmental pollution.

[0032] This structure simplifies the feeding process, allowing for quick switching between feeding and mixing states without the need for additional sealing devices, thus improving production efficiency. At the same time, by preventing dust or liquid splashes, it reduces health risks for operators and workplace safety hazards.

[0033] During the premixing stage of carbon nanotube conductive slurry, this anti-splashing mechanism ensures the uniformity and integrity of material input, reduces the intrusion of external impurities, and thus improves the quality of subsequent mixing and product consistency.

[0034] Specifically, a movable gap 32 is provided between the fixed plate 30 and the supporting annular plate 21, and the sealing circular plate 40 is adapted to the movable gap 32 and is disposed in the movable gap 32.

[0035] In this embodiment, the movable gap 32 provides a precise axial positioning space for the sealing disc 40, ensuring that the sealing disc 40 always maintains a stable gap fit with the fixed plate 30 and the supporting annular plate 21 during rotation. This design not only avoids rotational jamming, but also forms a dynamic sealing interface through gap size control, effectively isolating the internal space of the mixing tank 20 and preventing the slurry from escaping or external contaminants from entering during the mixing process.

[0036] Specifically, the fixing plate 30 is provided with an arc-shaped guide groove 31;

[0037] The sealing circular plate 40 is provided with a guide ring 43, which is matched in position and size with the arc-shaped guide groove 31. The guide ring 43 is rotatably disposed in the arc-shaped guide groove 31, so that the sealing circular plate 40 is rotatably disposed in the movable gap 32.

[0038] In this embodiment, the matching design of the guide ring 43 and the arc-shaped guide groove 31 forms a rigid rotating pair, which forcibly constrains the sealing disc 40 to move along a predetermined arc trajectory, completely eliminating the risk of radial offset or axial sway, ensuring that the opening and closing action of the feeding notch 41 and the fixed plate 30 is accurately aligned, and improving the reliability of the anti-splash function.

[0039] Specifically, two sets of positioning plates 50 are provided on both sides of the fixing plate 30, and positioning grooves 51 are provided on the fixing plate 30. The two sets of positioning grooves 51 are symmetrically arranged, and the sealing circular plate 40 cooperates with the positioning grooves 51.

[0040] Specifically, the sealing circular plate 40 is provided with two sets of positioning rods 42, and the two sets of positioning rods 42 are respectively arranged on both sides of the fixing plate 30;

[0041] The sealing disc 40 rotates around the axis supporting the annular plate 21, causing the positioning rod 42 to enter the positioning groove 51 to position and restrict the sealing disc 40.

[0042] In this embodiment, when the sealing disc 40 rotates to a preset position where the feeding notch 41 coincides with or is misaligned with the fixed plate 30, the positioning rod 42 automatically embeds into the positioning groove 51, forming a rigid mechanical limit. This design completely eliminates the accidental displacement of the sealing disc 40 caused by vibration or inertia, ensuring the long-term stability of the anti-splash sealing state or the feeding state, and avoiding the risk of seal failure caused by position drift;

[0043] The symmetrically distributed positioning grooves 51 and positioning rods 42 constitute a dual-position positioning system, which enables the sealing disc 40 to obtain definite tactile and auditory feedback in both the "open" and "closed" key positions, significantly reducing the adjustment time for operators.

[0044] Specifically, a fixing block 60 is provided in the positioning groove 51, and two sets of slopes 61 are symmetrically arranged on the fixing block 60.

[0045] In this embodiment, when the positioning rod 42 extends into the positioning groove 51, the positioning rod 42 contacts the slope 61 of the fixing block 60, causing the positioning plate 50 to deform until the positioning rod 42 is fully extended into the positioning groove 51. The positioning plate 50 then returns to its original shape and clamps the positioning rod 42, thereby improving the stability of the sealing disc 40.

[0046] Specifically, the length of the cross-sectional shape of the feeding notch 41 is less than the length of the cross-sectional shape of the fixed plate 30, and the width of the cross-sectional shape of the feeding notch 41 is less than the width of the cross-sectional shape of the fixed plate 30.

[0047] In this case, a sealing gasket with a matching shape is provided at the feeding notch 41. When the feeding notch 41 coincides with the fixing plate 30, the sealing gasket contacts the fixing plate 30 to complete the sealing process.

[0048] In this embodiment, when the sealing disc 40 rotates to the closed position, the projection area of ​​the fixed plate 30 completely covers the feeding notch 41, forming a static sealing interface with redundant dimensions, ensuring that the inside of the mixing tank 20 is in a completely closed state, effectively preventing the aerosol from escaping or the droplets from splashing when the carbon nanotube conductive slurry is stirred at high speed.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
