Description

Technical Field

[0001] This application relates to the field of viscosity reduction technology, specifically a pipeline device for reducing the viscosity of conductive carbon slurry. Background Technology

[0002] Conductive carbon paste is a gel-like substance composed of conductive particles and a solvent. The conductive particles are typically materials with good electrical conductivity, such as carbon nanotubes and carbon black, while the solvent is the medium used for dilution and gel formation, such as water or organic solvents. Conductive carbon paste possesses good conductivity and plasticity, making it suitable for applications such as the preparation of conductive films, conductive inks, and conductive coatings. It has broad application prospects in electronics, optoelectronics, and energy fields.

[0003] When slurry is transported in pipelines, it can become sticky. Usually, some chemicals are added to reduce the viscosity of the slurry. However, this requires additional machinery and increases costs. At the same time, other substances are introduced into the slurry during transportation, making the entire transmission process more complicated.

[0004] Therefore, it is necessary to provide a piping device for reducing the viscosity of conductive carbon slurry to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a pipeline device for reducing the viscosity of conductive carbon slurry, so as to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: a pipeline device for reducing viscosity of conductive carbon slurry, including a viscosity-reducing pipe group, wherein the viscosity-reducing pipe group includes a plurality of transmission pipes connected sequentially along the slurry flow direction, wherein the transmission pipe located on the upstream side of the viscosity-reducing pipe group is connected to the feed pipe section, and the transmission pipe located on the downstream side of the viscosity-reducing pipe group is connected to the discharge pipe section.

[0007] One end of the transmission pipe is a small equal diameter pipe section, and the other end is a large equal diameter pipe section. The diameter of the small equal diameter pipe section is smaller than that of the large equal diameter pipe section, and a variable diameter pipe section is provided between the small equal diameter pipe section and the large equal diameter pipe section.

[0008] The cross-sectional area of ​​the variable diameter pipe section gradually increases from the end near the smaller equal diameter pipe section to the end near the larger equal diameter pipe section.

[0009] Furthermore, one end of the feed pipe section is fixedly connected to a feed flange, one end of the discharge pipe section is fixedly connected to a discharge flange, the end of the small equal diameter pipe section away from the variable diameter pipe section is fixedly connected to a small diameter flange, and the end of the large equal diameter pipe section away from the variable diameter pipe section is fixedly connected to a large diameter flange.

[0010] Furthermore, the feed pipe section is fixedly connected to the small diameter flange on the small equal diameter pipe section via the feed flange, the large equal diameter pipe section is fixedly connected to the small diameter flange on the adjacent small equal diameter pipe section via the large diameter flange, the large equal diameter pipe section of the preceding transmission pipe is fixedly connected to the small diameter flange on the following transmission pipe via the large diameter flange, and the large equal diameter pipe section of the last transmission pipe is fixedly connected to the discharge flange of the discharge pipe section via the large diameter flange.

[0011] Furthermore, the feed pipe section is fixedly connected to the large-diameter flange on the large equal-diameter pipe section via the feed flange, the small equal-diameter pipe section is fixedly connected to the large-diameter flange on the adjacent large equal-diameter pipe section via the small-diameter flange, the small equal-diameter pipe section of the preceding transmission pipe is fixedly connected to the large-diameter flange on the following large equal-diameter pipe section via the small-diameter flange, and the small equal-diameter pipe section of the last transmission pipe is fixedly connected to the discharge flange of the discharge pipe section via the small-diameter flange.

[0012] Furthermore, the feed pipe section is fixedly connected to the large-diameter flange on the large equal-diameter pipe section via the feed flange, the small equal-diameter pipe section is fixedly connected to the small-diameter flange on the adjacent small equal-diameter pipe section via the small-diameter flange, the large equal-diameter pipe section of the preceding transmission pipe is fixedly connected to the large-diameter flange on the following transmission pipe via the large-diameter flange, and the large equal-diameter pipe section of the last transmission pipe is fixedly connected to the discharge flange of the discharge pipe section via the large-diameter flange.

[0013] The beneficial effects of this application are as follows: The pipeline device provided in this application for reducing the viscosity of conductive carbon slurry, by setting up several freely connectable transmission pipes, changes the flow rate of the slurry, thereby generating a certain shear force and reducing the adhesion of the slurry. It does not require additional machinery to provide shear force, nor does it introduce other substances. This solves the technical problem that slurry adhesion occurs during pipeline transportation, which usually involves adding chemical substances to reduce slurry viscosity. However, this increases the need for additional machinery and costs, and also introduces other substances during slurry transportation, making the entire transmission process more complex.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1-9As shown, this application provides a technical solution: a pipeline device for reducing the viscosity of conductive carbon slurry, including a viscosity-reducing pipe group, the viscosity-reducing pipe group including a plurality of transmission pipes 3 connected sequentially along the slurry flow direction, the transmission pipe 3 located on the upstream side of the viscosity-reducing pipe group is connected to the feed pipe section 1, and the transmission pipe 3 located on the downstream side of the viscosity-reducing pipe group is connected to the discharge pipe section 2.

[0031] One end of the transmission pipe 3 is a small equal diameter pipe section 31, and the other end is a large equal diameter pipe section 32. The diameter of the small equal diameter pipe section 31 is smaller than that of the large equal diameter pipe section 32. A variable diameter pipe section 33 is provided between the small equal diameter pipe section 31 and the large equal diameter pipe section 32.

[0032] The cross-sectional area of ​​the reducing pipe section 33 gradually increases from the end near the small equal diameter pipe section 31 to the end near the large equal diameter pipe section 32.

[0033] One end of the feed pipe section 1 is fixedly connected to the feed flange 11, one end of the discharge pipe section 2 is fixedly connected to the discharge flange 21, one end of the small equal diameter pipe section 31 away from the diameter reducing pipe section 33 is fixedly connected to the small diameter flange 311, and one end of the large equal diameter pipe section 32 away from the diameter reducing pipe section 33 is fixedly connected to the large diameter flange 321.

[0034] In Example 1, the flow rate in transmission pipe 3 changes abruptly from the large diameter to the small diameter.

[0035] Specifically, the feed pipe section 1 is fixedly connected to the small diameter flange 311 on the small equal diameter pipe section 31 via the feed flange 11. The large equal diameter pipe section 32 is fixedly connected to the small diameter flange 311 on the adjacent small equal diameter pipe section 31 via the large diameter flange 321. The large equal diameter pipe section 32 of the previous transmission pipe 3 is fixedly connected to the small diameter flange 311 on the next transmission pipe 3 via the large diameter flange 321. The large equal diameter pipe section 32 of the last transmission pipe 3 is fixedly connected to the discharge flange 21 of the discharge pipe section 2 via the large diameter flange 321.

[0036] The large equal diameter pipe section 32 of the preceding transmission pipe 3 is connected to the small equal diameter pipe section 31 of the following transmission pipe 3. The slurry fluid flows in the variable diameter pipe section 33, and the flow rate increases from small to large. When flowing from the large equal diameter pipe section 32 of the preceding transmission pipe 3 to the small equal diameter pipe section 31 of the following transmission pipe 3, the large flow rate suddenly becomes a small flow rate. Most of the slurry will be squeezed and impacted by the pipe wall, generating a certain shear force. The faster the flow rate, the stronger the shear force, which has the effect of reducing viscosity.

[0037] In Example 2, the flow rate in transmission pipe 3 changes abruptly from the small diameter to the large diameter.

[0038] Specifically, the feed pipe section 1 is fixedly connected to the large diameter flange 321 on the large equal diameter pipe section 32 via the feed flange 11, the small equal diameter pipe section 31 is fixedly connected to the large diameter flange 321 on the adjacent large equal diameter pipe section 32 via the small diameter flange 311, the small equal diameter pipe section 31 of the previous transmission pipe 3 is fixedly connected to the large diameter flange 321 on the next transmission pipe 3 via the small diameter flange 311, and the small equal diameter pipe section 31 of the last transmission pipe 3 is fixedly connected to the discharge flange 21 of the discharge pipe section 2 via the small diameter flange 311.

[0039] The small equal diameter pipe section 31 of the preceding transmission pipe 3 is connected to the large equal diameter pipe section 32 of the following transmission pipe 3. The slurry fluid flows in the variable diameter pipe section 33, and the flow rate decreases from large to small. When flowing from the small equal diameter pipe section 31 of the preceding transmission pipe 3 to the large equal diameter pipe section 32 of the following transmission pipe 3, the small flow rate suddenly becomes a large flow rate. A large portion of the slurry will be squeezed and impacted by the pipe wall, generating a certain shear force. The faster the flow rate, the stronger the shear force, which has the effect of reducing viscosity.

[0040] Example 3: The flow rate in transmission tube 3 changes gradually.

[0041] Specifically, the feed pipe section 1 is fixedly connected to the large diameter flange 321 on the large equal diameter pipe section 32 via the feed flange 11. The small equal diameter pipe section 31 is fixedly connected to the small diameter flange 311 on the adjacent small equal diameter pipe section 31 via the small diameter flange 311. The large equal diameter pipe section 32 of the preceding transmission pipe 3 is fixedly connected to the large diameter flange 321 on the following transmission pipe 3 via the large diameter flange 321. The large equal diameter pipe section 32 of the last transmission pipe 3 is fixedly connected to the discharge flange 21 of the discharge pipe section 2 via the large diameter flange 321.

[0042] The small equal diameter section 31 of the preceding transmission pipe 3 is connected to the small equal diameter section 31 of the following transmission pipe 3, and the large equal diameter section 32 of the preceding transmission pipe 3 is connected to the large equal diameter section 32 of the following transmission pipe 3. The slurry fluid flows in the variable diameter section 33. Through the connection between the small equal diameter section 31 of the preceding transmission pipe 3 and the small equal diameter section 31 of the following transmission pipe 3, and the connection between the large equal diameter section 32 of the preceding transmission pipe 3 and the large equal diameter section 32 of the following transmission pipe 3, the flow rate changes gradually, the shear force is small, and excessive residual slurry will not be generated.

[0043] In summary, this device, by incorporating several freely connectable transfer pipes, alters the slurry flow rate, thereby generating a certain shear force and reducing slurry adhesion. It eliminates the need for additional machinery to provide shear force and avoids the possibility of introducing other substances. This solves the technical problem of slurry adhesion during pipeline transportation, which typically involves adding chemicals to reduce viscosity, thus increasing costs and introducing other substances, making the entire transfer process complex.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
