Description

Technical Field

[0001] This utility model relates to the field of slurry technology, and in particular to an anti-settling dispersant addition device for carbon nanotube slurries. Background Technology

[0002] Carbon nanotube slurry refers to a suspension formed by uniformly dispersing carbon nanotubes in a liquid medium. Carbon nanotubes themselves have a strong tendency to agglomerate and will quickly settle and clump, leading to slurry failure. Therefore, preventing settling and adding dispersants are key steps to ensure the usability of the slurry.

[0003] Patent CN211487332U discloses an additive for a high molecular weight organic polymer dispersant. It includes a funnel-shaped collecting hopper, a top plate, an inlet pipe, a liquid feeding pipe, a cylinder, an outlet pipe, a mixer structure, a baffle, a support column, a base, a liquid storage structure, and a battery. The funnel-shaped collecting hopper is threadedly connected to the upper part of the liquid feeding pipe. When using this patent, an electric motor is run, which drives the support column. The rotation of the support column causes the stirring blades to stir. However, in the aforementioned prior art patent, the stirring blades are only located in the lower part of the cylinder's inner cavity and do not cover the entire inner cavity. After the slurry enters from the funnel-shaped collecting hopper, it accumulates in the upper part of the cylinder's inner cavity, resulting in excessively high local concentrations.

[0004] Therefore, there is a need for a device for adding an anti-settling dispersant to carbon nanotube slurry that provides uniform stirring. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, where the stirring blades are only located in the lower part of the inner cavity of the cylinder and do not cover the entire inner cavity, the slurry will accumulate in the upper part of the inner cavity after entering from the funnel-shaped collection hopper, resulting in excessively high local concentration, this utility model provides a uniform stirring device for adding an anti-settling dispersant for carbon nanotube slurry.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: A device for adding an anti-settling dispersant to carbon nanotube slurry, comprising a base, a mixing cylinder, and a discharge pipe. The mixing cylinder is fixedly connected to the base, and the discharge pipe is connected to the lower part of the mixing cylinder. The device also includes a fixed seat, a sliding sleeve, a stirring frame, a first motor, a fixed rod, a fixed ring, and a guide seat. The fixed seat is fixedly connected to the upper part of the mixing cylinder, and the fixed ring is fixedly connected to the middle part of the fixed seat. A sliding sleeve is slidably mounted on the fixed ring, and the first motor is mounted on the sliding sleeve. The stirring frame is mounted on the output shaft of the first motor and slides within the sliding sleeve. A fixed rod is fixedly connected to the stirring frame, and a guide seat is fixedly connected to the fixed ring. When the fixed rod rotates, it can be squeezed by the guide seat to move up and down.

[0007] More preferably, it also includes a mounting base, a feeding cylinder, a feeding pipe, a storage tank, a rotating shaft, a feeding plate, and a second motor. The mounting base is fixedly connected to the upper part of the mixing cylinder, the feeding cylinder is fixedly connected to the mounting base, the feeding pipe is connected to the feeding cylinder and passes through the mixing cylinder, the storage tank is connected to the top of the feeding cylinder, the second motor is installed on the right side of the feeding cylinder, the rotating shaft is installed on the output shaft of the second motor through a coupling, the feeding plate is fixedly connected to the rotating shaft and is located inside the feeding cylinder.

[0008] More preferably, it also includes a first magnetic ring, a protective cover, and a second magnetic ring. The storage tank is covered with a protective cover, and a second magnetic ring is embedded in the protective cover. The storage tank is also covered with a first magnetic ring, and the first magnetic ring and the second magnetic ring are attracted to each other.

[0009] More preferably, the cross-section of the feed plate is cross-shaped.

[0010] More preferably, a valve is installed on the discharge pipe.

[0011] More preferably, the base has four mounting holes.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The fixed rod rotates while the stirring frame rotates, and the fixed rod contacts and is squeezed with the guide seat, forcing the stirring frame, the first motor and the sliding sleeve to move up and down, breaking the bottom sediment layer, so that the settled particles are resuspended, improving the uniformity and stability of the slurry, and avoiding excessive local concentration or blockage.

[0013] 2. By starting the second motor, the output shaft of the second motor drives the rotating shaft to rotate the cross-shaped feeding plate and quantitatively add it into the four cavities between the feeding cylinder and the feeding plate. Each 90° rotation completes one quantitative delivery, ensuring that the dispersant is added evenly and preventing local agglomeration.

[0014] 3. By placing the protective cover on the storage tank, the protective cover on the top of the storage tank is sealed by the magnetic attraction of the first magnetic ring and the second magnetic ring, preventing the dispersant from getting damp or contaminated. Attached Figure Description

The mixing cylinder 2 is fixedly connected to the base 1, and the discharge pipe 3 is connected to the lower part of the mixing cylinder 2. The system also includes a fixed seat 4, a sliding sleeve 5, a stirring frame 6, a first motor 7, a fixed rod 8, a fixed ring 9, and a guide seat 10. The fixed seat 4 is welded to the upper part of the mixing cylinder 2, and the fixed ring 9 is welded to the middle part of the fixed seat 4. The sliding sleeve 5 is slidably mounted on the fixed ring 9. The first motor 7 is bolted to the sliding sleeve 5. The stirring frame 6 is mounted on the output shaft of the first motor 7. The stirring frame 6 slides inside the sliding sleeve 5. The fixed rod 8 is fixedly connected to the stirring frame 6, and the guide seat 10 is fixedly connected to the fixed ring 9. When the fixed rod 8 rotates, it can be squeezed by the guide seat 10 to move up and down.

[0023] See Figure 1 , Figure 2 and Figure 5 As shown, a valve is installed on the discharge pipe 3.

[0024] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, there are four mounting holes on the base 1.

[0025] When using this device, carbon nanotube slurry is placed in mixing cylinder 2 and a dispersant is added. Then, the first motor 7 is started. The output shaft of the first motor 7 drives the stirring frame 6 to rotate, stirring the slurry to prevent sedimentation. While the stirring frame 6 is rotating, the fixed rod 8 is also rotating. The fixed rod 8 contacts the guide seat 10 and is squeezed, forcing the stirring frame 6, the first motor 7 and the sliding sleeve 5 to move up and down, breaking the bottom sediment layer, so that the settled particles are resuspended, improving the uniformity and stability of the slurry, and avoiding excessive local concentration or blockage. The stirred carbon nanotube slurry is discharged from the discharge pipe 3.

[0026] Example 2: Based on Example 1, refer to Figure 1 , Figure 4 and Figure 5 As shown, it also includes a mounting base 11, a feeding cylinder 12, a feeding pipe 13, a storage tank 14, a rotating shaft 15, a feeding plate 16, and a second motor 17. The mounting base 11 is fixedly connected to the upper part of the mixing cylinder 2, and the feeding cylinder 12 is fixedly connected to the mounting base 11. The feeding pipe 13 is connected to the feeding cylinder 12 and passes through the mixing cylinder 2. The storage tank 14 is connected to the top of the feeding cylinder 12. The second motor 17 is installed on the right side of the feeding cylinder 12 by bolt connection. The rotating shaft 15 is installed on the output shaft of the second motor 17 by a coupling. The feeding plate 16 is fixedly connected to the rotating shaft 15 and is located inside the feeding cylinder 12.

[0027] See Figure 4 As shown, the cross-section of the feed plate 16 is cross-shaped.

[0028] When adding dispersant, first pour an appropriate amount of dispersant into the mixing cylinder 2. The dispersant enters the feeding cylinder 12. Then start the second motor 17. The output shaft of the second motor 17 drives the rotating shaft 15 to rotate the cross-shaped feeding plate 16 and add it quantitatively to the four cavities between the feeding cylinder 12 and the feeding plate 16. Each 90° rotation completes one quantitative delivery, ensuring that the dispersant is added evenly and preventing local agglomeration.

[0029] See Figure 1 and Figure 5 As shown, it also includes a first magnetic ring 18, a protective cover 19, and a second magnetic ring 20. The storage tank 14 is covered with a protective cover 19, and the second magnetic ring 20 is embedded in the protective cover 19. The first magnetic ring 18 is embedded in the storage tank 14, and the first magnetic ring 18 and the second magnetic ring 20 are attracted to each other.

[0030] When an appropriate amount of carbon nanotube slurry is poured into the mixing cylinder 2, the protective cover 19 is placed on the storage tank 14. The protective cover 19 on the top of the storage tank 14 is sealed by the magnetic attraction of the first magnetic ring 18 and the second magnetic ring 20 to prevent the dispersant from getting damp or contaminated. At the same time, it is easy to quickly open and replenish the dispersant to ensure the purity of the added material.
