Mixed collection and compression device for dust and thin metal

A mixed collection and compression device, comprising:

• a separation mechanism (1), configured to sieve a flowing gas in the separation mechanism (1) into a dust-containing gas and a metal material;
• a filtering mechanism (2), connected to the separation mechanism (1), wherein the filtering mechanism (2) is configured to filter dust in the dust-containing gas;
• an inert powder adding mechanism (3), connected between the separation mechanism (1) and the filtering mechanism (2), wherein the inert powder adding mechanism (3) is configured to add inert powder into the dust-containing gas during transportation;
• a compression mechanism (4), connected to the separation mechanism (1), wherein the compression mechanism (4) is configured to collect and compress the metal material;
• and
• a power gas source (5), configured to provide a negative pressure environment for a gas inside the separation mechanism (1) to make the gas sequentially pass through the separation mechanism (1), the inert powder adding mechanism (3), and the filtering mechanism (2).
