AI Technical Summary

Technical Problem

In existing hot air drying and curing technologies, the uneven temperature of aircraft parts leads to a decline in coating curing quality, especially for longer parts such as beams and landing gear assemblies where the hot air curing temperature is uneven.

Method used

A gas circulation drying chamber for rapid curing of aircraft coatings was designed. The air outlet is moved by a mounting frame driven by a slide bar, screw, and electric motor. Combined with an axial impeller and heating tube, the airflow is evenly distributed. A dehumidification mechanism is also provided to control humidity and ensure the uniformity of temperature and humidity in the drying chamber.

Benefits of technology

It achieves uniform hot air drying of aircraft parts coatings, prevents coating blistering, improves curing effect, and maintains a suitable humidity environment through dehumidification mechanism to avoid coating curing problems.

Abstract

This utility model discloses a rapid curing gas circulation drying chamber for aircraft coatings, including a drying chamber. A circulating air drying mechanism is installed at the upper end of the drying chamber. The drying mechanism includes a slide rod, a screw, a fixed frame, a mounting frame, an axial impeller, a first motor, an air outlet, and a heating pipe. The slide rod is fixedly installed at the upper end of the drying chamber. A screw is movably installed between the slide rods inside the drying chamber via bearings. The fixed frame is movably fitted onto the surface of the slide rod, and the inner center of the fixed frame is threaded onto the outer surface of the screw. This utility model can perform reciprocating hot air drying and curing, ensuring a consistent drying temperature throughout the entire space of the drying chamber. Simultaneously, the continuously moving airflow effectively prevents direct airflow onto a fixed location on the aircraft parts, effectively preventing blistering of the coating due to high temperatures, thereby improving the drying and curing effect of the device.
