Description

Technical Field

[0001] This utility model relates to the field of battery separator extraction technology, and in particular to a battery separator extraction device. Background Technology

[0002] In a wet process production line, the battery separator needs to be extracted in an extraction tank to separate the white oil on the surface of the separator. However, the extractant used to separate the white oil is usually dichloromethane, which is a volatile and toxic liquid. The separator needs to be immersed in the extractant in the extraction tank to extract and separate the white oil. During the extraction process, the separator will be immersed in multiple extraction tanks connected in series in sequence.

[0003] When the diaphragm emerges from the extractant in the extraction tank, it carries a large amount of extractant on its surface. As the diaphragm leaves the extraction tank, it is scraped off by a scraper roller assembly. However, due to the small wrap angle between the scraper roller assembly and the diaphragm, the following problems arise: First, the diaphragm is prone to slipping, and tension fluctuations can easily lead to wrinkles. Second, the scraping effect is poor; the extractant carried out of the extraction tank, due to its volatility, will quickly evaporate and spread into the employee work area, affecting employee safety.

First feature "under", "below" and "under surface of" second feature includes that first feature is directly below and obliquely below second feature, or only indicates that horizontal height of first feature is less than second feature.

[0045] In the description of the embodiment, the orientation or position relationship of the terms "up", "down", "left", "right" and the like is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0046] As Figures 1 to 4 shown, the embodiment of the utility model provides a kind of battery separator extraction device, which includes box 1, inlet roller group 2, reversing roller group 3, liquid scraping roller group 4 and corner angle roller 5, and box 1 can be used to hold extraction liquid.

Corner angle roller 5 is arranged between reversing roller group 3 and liquid scraping roller group 4, and corner angle roller 5 can be above the liquid level of extraction liquid, membrane 6 is sequentially wound on inlet roller group 2, reversing roller group 3, corner angle roller 5 and liquid scraping roller group 4, and the output position of reversing roller group 3 and the input position of liquid scraping roller group 4 are both located on the first side of membrane 6, corner angle roller 5 contacts the second side of membrane 6, and corner angle roller 5 can press membrane 6 to increase the corner angle between membrane 6 and reversing roller group 3 and between membrane 6 and liquid scraping roller group 4.

The wrap angle roller 5 can not only pretreat the extraction liquid attached to the diaphragm 6 before the liquid scraping roller group 4 to reduce the attachment, but also increase the friction of the diaphragm 6 during the conveying process and improve the tension stability of the diaphragm 6 by contacting the diaphragm 6 with the roller surface of the wrap angle roller 5. In addition, the wrap angle roller 5 can be close to the connecting line of the reversing roller group 3 and the liquid scraping roller group 4 and extrude the diaphragm 6 along the vertical direction of the connecting line of the reversing roller group 3 and the liquid scraping roller group 4. The input position of the wrap angle roller 5 and the output position of the reversing roller group 3 are arranged on both sides of the diaphragm 6.
