Technical Field
[0001] This utility model relates to a device for filtering and purifying carbon nanotube conductive slurry. Background Technology
[0002] Carbon nanotube conductive pastes are widely used in lithium-ion batteries, supercapacitors, conductive coatings, and flexible electronic devices due to their excellent conductivity, high specific surface area, and mechanical strength. In these applications, the purity of the paste directly determines the performance and stability of the product. For example, impurities or non-uniform particles in the paste can lead to decreased conductivity, electrode material failure, or shortened device lifespan. Therefore, efficient filtration and purification of carbon nanotube conductive pastes are crucial steps to ensure their commercial application.
[0003] Currently, traditional carbon nanotube conductive slurry filtration and purification devices mainly rely on centrifugal separation technology. However, when cleaning residual impurities, traditional centrifugal filters often require disassembling the filter components (such as disassembling the filter housing or pipes), which is not only time-consuming and labor-intensive but may also lead to equipment seal failure or secondary pollution. In view of this, this utility model proposes a carbon nanotube conductive slurry filtration and purification device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a carbon nanotube conductive slurry filtration and purification device to solve the problems mentioned in the background art.

[0007] The filter housing is provided with an inlet pipe and an outlet pipe, both of which are connected to the inner cavity of the filter housing. The tank is provided with an outlet pipe connected to the inner cavity. The outlet pipe and the outlet pipe are matched in position and fixedly connected.

[0011] The sealing plug is displaced to the junction of the first connecting pipe and the second connecting pipe, so that the filter housing is in communication with the outside.

[0017] As an improvement to the above technical solution, the tank is provided with a cleaning pipe, and the cleaning pipe is provided with a sealing plate connected by bolts.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] By setting up a rotatable filter housing with multiple sets of filter holes evenly opened on its surface, the device utilizes centrifugal force to automatically separate qualified components and impurities in the carbon nanotube conductive slurry during the rotation of the filter housing. Qualified slurry (meeting the filter holes) enters the inner cavity of the tank through the filter holes and is discharged from the outlet pipe; while unqualified components (such as large particles or impurities) are retained in the inner cavity of the filter housing. This design achieves continuous and efficient solid-liquid separation, significantly improves the filtration rate and slurry purity, solves the problems of low efficiency and easy clogging of traditional filtration methods, and ensures the consistency and stability of the product.
[0020] The sealing component installed on the discharge pipe can control the opening and closing of the discharge pipe. When it is necessary to clean residual impurities inside the filter housing, the sealing component can quickly open the discharge pipe to connect it to the outside, facilitating the introduction of cleaning fluid for rinsing. This design avoids the problems of disassembly or complex operation required by traditional devices, simplifies the maintenance process, significantly reduces equipment downtime, improves the durability and ease of operation of the device, and is suitable for industrial continuous production environments.

Detailed Implementation
[0028] 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.
[0029] Example:
[0030] like Figure 1-6 As shown, this embodiment proposes a carbon nanotube conductive slurry filtration and purification device, including a tank 10, a rotatable filter housing 20 is provided inside the tank 10, and multiple sets of filter holes 21 are uniformly opened on the surface of the filter housing 20.
[0031] The filter housing 20 is provided with an inlet pipe 22 and an outlet pipe 23, both of which are connected to the inner cavity of the filter housing 20. The tank body 10 is provided with an outlet pipe 11 connected to the inner cavity. The outlet pipe 23 is matched with the outlet pipe 11 in position and is fixedly connected to the outlet pipe 11. A sealing component 40 is provided on the outlet pipe 23, which cooperates with the outlet pipe 23 to control the opening and closing of the outlet pipe 23.
[0032] In this embodiment, when purifying the carbon nanotube conductive slurry, the raw material is introduced into the filter housing 20 through the feed pipe 22. As the filter housing 20 rotates, the raw material that meets the pore size of the filter hole 21 is discharged from the filter hole 21 under the action of centrifugal force and enters the inner cavity of the tank 10. Then, the qualified raw material flows out from the liquid outlet pipe 11, while the unqualified raw material is retained in the inner cavity of the filter housing 20. When the filter housing 20 needs to be cleaned, the discharge pipe 23 is opened to the outside through the sealing component 40, and then cleaning liquid is introduced into the filter housing 20 for rinsing.
[0033] By setting a rotatable filter housing 20 and uniformly opening multiple sets of filter holes 21 on its surface, the device utilizes centrifugal force to automatically separate qualified components and impurities in the carbon nanotube conductive slurry during the rotation of the filter housing 20. Qualified slurry (meeting the filter holes 21) enters the inner cavity of the tank 10 through the filter holes 21 and is discharged from the liquid outlet pipe 11; while unqualified components (such as large particles or impurities) are retained in the inner cavity of the filter housing 20. This design achieves continuous and efficient solid-liquid separation, significantly improves the filtration rate and slurry purity, solves the problems of low efficiency and easy clogging of traditional filtration methods, and ensures the consistency and stability of the product.
[0034] The sealing component 40 installed on the discharge pipe 23 can control the opening and closing of the discharge pipe 23. When it is necessary to clean the residual impurities inside the filter housing 20, the sealing component 40 can quickly open the discharge pipe 23 to connect it with the outside, making it easy to introduce cleaning fluid for rinsing. This design avoids the problems of disassembly or complicated operation required by traditional devices, simplifies the maintenance process, significantly reduces equipment downtime, improves the durability and ease of operation of the device, and is suitable for industrial continuous production environments.
[0035] Specifically, the discharge pipe 23 is provided with a first connecting pipe 231 and a second connecting pipe 232. The second connecting pipe 232 is fixedly connected to the first connecting pipe 231. The inner cavities of the second connecting pipe 232 and the first connecting pipe 231 are connected. The sealing component 40 is disposed in the first connecting pipe 231.
[0036] In this embodiment, when no material is being discharged, the sealing component 40 is placed in the first connecting pipe 231, so that the second connecting pipe 232 is not connected to the inner cavity of the first connecting pipe 231. When material is being discharged, the sealing component 40 is displaced in the first connecting pipe 231, so that the second connecting pipe 232 is connected to the first connecting pipe 231, and the residual unqualified components in the filter housing 20 are discharged through the second connecting pipe 232.
[0037] Specifically, the first connecting pipe 231 is rotatably connected to the filter housing 20, and both the first connecting pipe 231 and the second connecting pipe 232 are installed through the liquid outlet pipe 11.
[0038] Specifically, the sealing assembly 40 includes a sealing plug 42, which is slidably disposed in the inner cavity of the first connecting tube 231;
[0039] The sealing plug 42 is displaced to the junction of the first connecting pipe 231 and the second connecting pipe 232, so that the filter housing 20 is in communication with the outside.
[0040] Specifically, the first connecting pipe 231 is provided with a sealing end face 233, and the sealing plug 42 is provided with a driving screw 41;
[0041] The drive screw 41 is disposed through the sealing end face 233, and the drive screw 41 is rotatably disposed on the sealing end face 233.
[0042] In this embodiment, when it is necessary to control the displacement of the sealing plug 42, the drive screw 41 is rotated. Through the threaded engagement between the drive screw 41 and the sealing end face 233, the sealing plug 42 is displaced in the first connecting pipe 231 until the sealing plug 42 is displaced to the junction of the first connecting pipe 231 and the second connecting pipe 232, so that the inner cavity of the filter housing 20 is connected to the outside through the second connecting pipe 232 for the discharge process.
[0043] Specifically, a transmission sleeve 30 is provided on the tank body 10, the transmission sleeve 30 is rotatably mounted on the tank body 10, and the transmission sleeve 30 is also fixedly connected to the filter housing 20.
[0044] Specifically, the feed pipe 22 extends through the transmission sleeve 30 into the inner cavity of the filter housing 20. The feed pipe 22 is rotatably disposed in the transmission sleeve 30. The transmission sleeve 30, the filter housing 20, and the feed pipe 22 are coaxially arranged.
[0045] The surface of the transmission sleeve 30 is provided with multiple sets of belt connecting ring grooves 31.
[0046] In this embodiment, when the filter housing 20 is rotated, a transmission belt is installed in the belt connecting ring groove 31 and the transmission belt is connected to the rotating shaft of the drive motor so as to drive the filter housing 20 to rotate and complete the centrifugal filtration and purification process.
[0047] Specifically, the tank body 10 is provided with a cleaning pipe 12, and the cleaning pipe 12 is provided with a sealing plate 13 connected by bolts.
[0048] In this embodiment, when cleaning the inside of the filter housing 20, the liquid outlet pipe 11 is sealed and the cleaning pipe 12 is opened. Then, cleaning liquid is injected into the tank 10 through the cleaning pipe 12, so that the cleaning liquid comes into contact with the unqualified components remaining in the filter housing 20. The filter housing 20 continues to rotate, and the second connecting pipe 232 is connected to the inner cavity of the filter housing 20. The unqualified components are guided out from the second connecting pipe 232 by the cleaning liquid.
[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.
