AI Technical Summary

Technical Problem

The centrifugal fan in the existing granulator cannot filter external impurities during air intake, which leads to equipment damage and reduces its service life.

Method used

An external circulation granulator was designed, comprising a filter box, a cleaning component, and a replacement component. The filter screen is cleaned using a threaded rod driven by a servo motor and a cleaning brush. Combined with the disassembly function of a magnet, as well as the extension block and drive block of the replacement component, the cleaning and replacement of the filter screen can be achieved, preventing impurities from entering the centrifugal fan.

Benefits of technology

It effectively improves the permeability and cleaning efficiency of the filter screen, prevents dust and lint from entering the centrifugal fan, and extends the service life of the equipment.
