[0002] Carbon nanotube conductive paste is a key auxiliary material for lithium-ion batteries. It mainly forms a line contact conductive network between active substances, which plays an important role in improving the battery's conductivity, capacity utilization rate performance, and cycle performance. Conductive paste, also known as conductive glue, is a mixture of precious metal powder and base metal powder, glass powder and synthetic resin. After adding solvent, it can be made into a material or graphite-like object. The particle size of the metal powder is about 1 to 2um. The ultrafine powder slurry with a particle size of tens of nm is being developed. The practical ones are Ag (30% to 85% Ag, the rest is epoxy resin and glass powder), Au (60% to 85% Au, the rest is epoxy resin and glass powder), Au-Pd (50% to 70% Au, 10% to 20% Pd, the rest is epoxy resin and glass powder), Cu (70% to 80% Cu, the rest is epoxy resin and glass powder), Ni (80% to 90% Ni, the rest is epoxy resin and glass powder) and other pastes, these pastes are applied to the required parts of the substrate by screen printing or other methods, and then fired at a temperature of 400 to 1000 ° C to form a conductor. It is mainly used for the wiring of thick film integrated circuits, electrodes of ceramic capacitors, and leads of hybrid integrated circuits.

[0003] There will be certain impurities in the carbon nanotube conductive slurry during the transportation process, and it needs to be filtered before it can be used for subsequent production and processing.

Since the carbon nanotube conductive slurry has a certain viscosity, impurities are prone to precipitation and accumulation. The viscous impurities cannot be discharged. After a period of time, the impurities will accumulate more and more, affecting the filtration efficiency of the carbon nanotube conductive slurry. Utility Model Content

[0024] A conductive slurry filter cartridge 3 is fixedly installed inside the pipeline filter 1 to filter the transported conductive slurry;

[0025] In this embodiment:

[0026] When the staff needs to filter the carbon nanotube conductive slurry, the staff installs the pipeline filter 1 on the conveying pipe of the carbon nanotube conductive slurry. At this time, the carbon nanotube conductive slurry flows into the pipeline filter 1 from the conductive slurry input port 11. After the carbon nanotube conductive slurry is filtered by the conductive slurry filter cartridge 3, the impurities will be blocked and then precipitated downward at the bottom of the pipeline filter 1. The filtered carbon nanotube conductive slurry will be transported from the conductive slurry output port 12 to the subsequent production device for production. When the staff needs to clean the impurities precipitated in the pipeline filter 1, the cleaning valve 131 is manually opened, and the impurities precipitated at the bottom of the pipeline filter 1 will be discharged from the impurity discharge port 13 to the external impurity collection box for Centralized collection. During the process of impurity discharge, due to the certain viscosity of the carbon nanotube conductive slurry, impurities will remain at the bottom of the box of the pipeline filter 1 and cannot be discharged. At this time, the staff presses the two sets of cleaning rods, and the two sets of cleaning rods press the two sets of springs inward. The two sets of cleaning rods scrape the impurities accumulated at the bottom of the box of the pipeline filter 1 to the impurity discharge port 13, which is convenient for the discharge of impurities. Then the staff releases the two sets of cleaning rods, and the four sets of springs reset and drive the two sets of cleaning rods to reset. At this time, the staff repeatedly presses down the two sets of cleaning rods to clean the precipitated impurities more thoroughly, improve the cleaning efficiency of impurities, prevent the pipeline filter 1 from being blocked due to excessive accumulation of impurities, reduce the maintenance frequency of the pipeline filter 1, and reduce the production cost of the factory;

[0027] The transported carbon nanotube conductive slurry can be filtered through the conductive slurry filter cartridge 3, and impurities will settle downward at the bottom of the pipeline filter 1, and will not block the conductive slurry filter cartridge 3, thereby improving the filtration efficiency of the conductive slurry filter cartridge 3. The impurities precipitated at the bottom of the pipeline filter 1 can be discharged in a centralized manner using the impurity discharge port 13 to prevent excessive accumulation of impurities that may reduce the efficiency of the pipeline filter 1. The viscous impurities accumulated at the bottom of the pipeline filter 1 can be scraped out to the impurity discharge port 13 using two sets of cleaning rods, thereby improving the cleaning efficiency and effectively reducing the maintenance frequency of the pipeline filter 1.
