Description

Technical Field

[0001] The utility model relates to the field of filtering equipment, in particular to a solvent production filter. Background Art

[0002] In recent years, with the increasing degree of social informatization, electronic components have begun to develop in the direction of miniaturization, high frequency, broadband, high precision, integration and green environmental protection. As one of the basic components of electronic products, chip multilayer ceramic capacitors (MLCC) are mainly produced by tape casting. Most domestic manufacturers use non-aqueous tape casting process with polyvinyl butyral (PVB) as adhesive. This molding method uses a large amount of organic matter as solvent. Some of the organic matter contains fixed impurities, and bag filters are needed to filter the organic solvents during production and use.

[0003] However, in actual use, since the bag filter enters the top of the bag filter through the pressurized flow of organic solvent, the pressurized flow pushes the fluid through the filter holes of the filter bag, and the impurities are retained on the surface of the filter bag. The bag filter's closing cover is clamped and fixed with bolts and threaded sleeves on the top of the bag filter. Since the organic solvent is a pressurized fluid, its outflow turbulence will impact the inner wall of the closing cover, causing the closing cover to vibrate. After a long period of impact, the threaded sleeve on the top of the closing cover will loosen, resulting in a pressure relief gap at the connection between the closing cover and the top of the bag filter, affecting the filter bag's filtration and interception of impurities by pressure. Therefore, in response to the above-mentioned problems, the utility model proposes a solvent production filter. Utility Model Content
