AI Technical Summary

Technical Problem

Existing circulating air source heat pump drying towers require shutdown and disassembly of a large number of peripheral components when replacing the filter, resulting in long maintenance times.

Method used

A design was developed that involves creating an installation groove at the bottom of the heat exchange pipe, and installing a movable plate and a filter screen inside the groove. The filter screen can be quickly replaced by pulling out the movable plate, and the filter screen can be changed without disassembling surrounding components through the cooperation of a guide sleeve and a positioning rod.

Benefits of technology

It enables quick filter replacement, reduces maintenance time, avoids dust and fiber clogging of the heat pump system, and improves operational safety and efficiency.
