Mining porous spiral-type foam generating device

The invention discloses a mining porous spiral-type foam generating device. The mining porous spiral-type foam generating device comprises a compressed air joint (1), a nozzle body (2), a gas-liquid mixing chamber (5), porous spiral-type foamers (6), a foaming cylinder body (7) and a foam outlet joint (10), wherein the rear end of the nozzle body (2) is provided with at least one outlet nozzle; a nozzle cavity in the nozzle body (2) is of a circular truncated cone contracted shape; the compressed air joint is connected with the nozzle body; the nozzle body is installed at the inner side of the front end of the gas-liquid mixing chamber; the porous spiral-type foamers are installed in the foaming cylinder body. A multi-nozzle jet flow structure provided by the invention can achieve low-resistance high-efficiency mixing of a gas phase and a liquid phase. A wire surface high-multiple foaming and spiral low-resistance high-efficiency heat transfer mass transfer coupling mechanism is adopted for foaming, so that the foaming performance of the device is improved greatly; the generated foam is low in wind to foam ratio, is high in foaming quantity and is high in foam forming ratio; the resistance loss in the mixing and foaming process is reduced; the driving pressure of the device is improved; easily damage moving components in a turbulent flow foaming device are discarded; the device foaming reliability is improved.
