AI Technical Summary
The compressed air supplied by the air compressor in the existing laboratory muffle furnace has a high moisture content and cannot be used directly as a gas source, resulting in high experimental costs.
An air intake device for a laboratory muffle furnace was designed, including a housing, connecting pipe, air intake pipe, and purification and filtration assembly. The purification and filtration assembly consists of a drying tube and a filter tube, and is equipped with a three-way valve, a diverter pipe, a one-way valve, a main valve, and a flow meter to handle air circulation patterns and flow control for different air sources.
It effectively removes moisture from compressed air, reduces testing costs, improves the flexibility of the device and the ability to control gas flow rate, and meets the needs of different gas sources.
