Description

Technical Field

[0001] This utility model relates to the technical field of barrier filtration equipment, specifically a barrier filtration device. Background Technology

[0002] Pneumatic systems often include air filtration devices to protect the equipment's normal operation. These devices purify the air. Traditional filters consist of two concave steel meshes interlocked as a filter element, with a filtration area limited to the cross-sectional area of ​​the pipe inlet, effectively trapping impurities. To filter dust and impurities from the air, a filtration mechanism consisting of meshes and filter elements is typically used. However, after a period of use, impurities can clog the filter mechanism, requiring disassembly and cleaning. Existing barrier-type filters generally use screws for fixing, which hinders quick disassembly and cleaning, presenting certain drawbacks. Therefore, we propose a barrier-type filtration device.
