AI Technical Summary
Existing extrusion conveying devices have complex structures and cannot effectively remove gaseous impurities from flame arresters, resulting in unstable processing temperatures, uneven melt flow, and easy clogging.
A flame-retardant extrusion conveying device, including a drive mechanism and a vacuum exhaust system, was designed. By using a vacuum pump to remove gaseous impurities and combining it with the tapering design of the spiral conveyor cylinder, smooth material conveying and stable temperature are ensured.
It effectively removes gaseous impurities, improves the stability of processing temperature, avoids uneven melt flow and material blockage, and improves the efficiency and quality of material conveying.
