Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm production, in particular to a lithium battery diaphragm extract separation and processing device. Background Art

[0002] During the charge and discharge process of lithium-ion batteries, the diaphragm separates the positive and negative electrodes to prevent short circuits caused by contact between the two electrodes, absorbs sufficient electrolyte, provides sufficient electrolyte lithium ion channels, and has micropore self-closing protection functions. The lithium ion conductivity of the diaphragm is directly related to the overall performance of the lithium-ion battery. The performance of the diaphragm determines the battery's interface structure, electrolyte retention, and internal resistance, which in turn affects the battery's capacity, cycle performance, charge and discharge current density, and safety. Important characteristics; the existing wet-process diaphragm manufacturing method generally includes the following processes: batching casting → biaxial stretching → extraction → transverse stretching → winding inspection; among them, in the extraction process, the domestic wet-process lithium battery diaphragm industry generally uses dichloromethane as the extractant for white oil in the diaphragm, and the mixed extract of white oil and dichloromethane after extraction needs to be separated and used again through a distillation device.

[0003] When the existing processing equipment is in use, impurities will be attached to the surface of the scraper after use, which is inconvenient to clean.

[0004] The existing patent (publication number: CN219941814U) discloses a plant extract distiller, which can fully stir the extract through a stirring mechanism to fully heat the extract, scrape off the liquid adhering to the inside of the distiller body by a scraper, centrifuge the extract through a centrifugal disk to make the heating, boiling and evaporation more efficient, and quickly condense the evaporated gas into liquid through a conversion bottle and collect it in a conical flask, thereby fully separating the water, oil and solvent in the extract.

[0005] However, the above technical solution still has certain defects. When the processing equipment is in use, the scraper is driven to rotate by the agitator, and the liquid attached to the inner wall of the distiller is scraped off by the scraper. After long-term use, a large amount of impurities may be attached to the surface of the scraper, and the distiller body is integrated, so it is difficult to clean the outer wall of the scraper. If it is not cleaned in time, it may cause inconvenience during use. Therefore, a lithium battery diaphragm extract separation and processing equipment is proposed. Utility Model Content
