Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a precision filter which is easy to assemble. Background Art

[0002] With the acceleration of industrialization and modernization, the demand for precision filters in various industrial production, water treatment, air purification and other fields is growing. As a key device for removing tiny impurities in liquids or gases, the performance of precision filters is directly related to the efficiency of subsequent processes and the quality of the final product. However, traditional precision filter designs often have some limitations, which restrict their adaptability and ease of operation in different application scenarios.

[0003] First of all, in terms of installation and maintenance, traditional precision filters often require complex tools and a long time to disassemble and assemble, especially for occasions that require frequent replacement of filter elements or cleaning. This inefficient assembly method undoubtedly increases the difficulty of operation and downtime, which is not conducive to the continuous operation of the production line and rapid response to market demand.

[0004] Secondly, the flow regulation function of traditional precision filters is relatively simple, and most of them only provide filter screens with fixed pore sizes, which cannot flexibly adapt to the specific needs of filtration volume under different working conditions. When it is necessary to change the filtration rate or process media of different viscosities, it is often necessary to replace the entire filter unit, which not only increases maintenance costs but also affects production efficiency. In addition, the lack of an effective minimum flow control mechanism may lead to a decrease in filtration efficiency under low flow requirements, affecting the filtration effect. Therefore, we propose a precision filter that is easy to assemble. Utility Model Content
