AI Technical Summary

Technical Problem

Existing filters typically employ an integrated structure, requiring complete disassembly and replacement of the filter element when it reaches the end of its service life. This process is cumbersome and time-consuming, and the aluminum frame cannot be reused, increasing usage costs and wasting resources.

Method used

It adopts a plug-in design, which uses an L-shaped aluminum frame and plug-in flange combined with screws for fastening, enabling quick replacement of filter paper and reuse of aluminum frame. Corner code slides and limit slides are used to improve stability and safety.

Benefits of technology

It simplifies the filter paper replacement process, shortens replacement time, reduces usage costs, reduces resource waste, and improves work efficiency and the reliability of filtration effect.

Abstract

This utility model discloses a pluggable reusable filter, relating to the field of filter technology. The pluggable reusable filter includes a filter assembly, with an external mounting assembly. The mounting assembly includes an L-shaped aluminum frame and multiple pluggable flanges. The pluggable flange is mounted on the upper end of the L-shaped aluminum frame, and multiple L-shaped corner brackets are provided at the connection between two L-shaped aluminum frames. The pluggable flange includes a pluggable horizontal plate and a pluggable vertical plate, with the vertical plate located at one end of the horizontal plate. This solution solves the problem that existing filters typically use an integral structure where the aluminum frame and filter element are fixedly connected. When the filter element reaches the end of its service life and needs replacement, the entire filter must be disassembled, which is cumbersome and time-consuming. Furthermore, the integral structure prevents the aluminum frame from being reused, increasing usage costs and wasting resources.
