Description

Technical Field

[0001] The utility model relates to the field of filtering technology in the preparation of stripping liquid, in particular to a stripping liquid impurity filter. Background Art

[0002] Stripping fluid plays a vital role in the high-tech industry. For example, in the wet electronic chemicals required for LCD panel manufacturing, stripping fluid accounts for 31%, and in OLED panel manufacturing, stripping fluid accounts for as high as 44%. The preparation of stripping fluid includes raw material preparation and proportioning, raw material mixing and stirring, filtration and purification, filling and packaging, etc. During filtration and purification, various impurities such as particles, dust, oil, etc. may be mixed in the raw materials and during the manufacturing process, and there will be impurities of various sizes and properties. At the same time, in order to improve the filtration efficiency, a graded filtration method is required. After each filtration period, the solid impurities on it need to be cleaned up to avoid blockage and affect the subsequent filtration effect.

[0003] However, the existing multi-stage filtering stripping liquid device uses a large number of fasteners, such as screws, nuts, etc., which makes it troublesome to remove and clean the filter. This problem can be solved by using multiple single-stage filtering devices, but the transfer between the devices is also troublesome. Utility Model Content
