AI Technical Summary

Technical Problem

Existing breaker plates allow foreign substances to leak out with the resin, reducing the filtration accuracy of high-accuracy filters and leading to insufficient foreign substance removal.

Method used

A breaker plate design with a first plate and a second plate holding a filter member, where the first filter element with high filtration accuracy is compressed against the contact surface, and a second filter element with lower accuracy is positioned upstream to remove larger foreign substances, preventing resin leakage and maintaining filtration efficiency.

Benefits of technology

The design effectively suppresses resin leakage, allowing even finer foreign matter to be removed at the original high removal rate of the filter, ensuring the intended filtration accuracy is maintained.

Abstract

This breaker plate suppresses resin leakage from the periphery of the filter component, allowing the filter to perform at its intended filtration efficiency, thereby enabling the removal of even finer foreign matter with its inherently high removal rate. [Solution] The system comprises a first plate 2 and a second plate 3 that holds a filter member 4 consisting of a plurality of filter elements between the first plate 2. The filter member 4 includes a relatively large-diameter first filter member 41 which includes at least a first filter element 41a that has the highest filtration accuracy, and a second filter member 42 which has a smaller diameter and includes one or more filter elements that have lower filtration accuracy than the first filter element 41a. The filter member 4 is held in a state in which the peripheral edge of the first filter element 41a is pressed against and compressed by the contact surfaces 51, 52 of the holding portion 5 that holds the first filter member 41.
