摘要
A mine fireproofing and fire extinguishing foam generator, comprising a foaming cylinder (1), a venturi tube (2) disposed inside the foaming cylinder (1), a liquid line (4) passing through the wall of the foaming cylinder and into the venturi tube, and an atomizing nozzle (3) disposed at the throat portion of the venturi tube and connected to the extended end of the liquid line; the other end of the liquid line is connected to a foaming agent container (6); a pump (5) is installed on the liquid line; a gas nozzle (10) is disposed behind the atomizing nozzle; the gas nozzle (10) is connected to an air compressor (7) via an air inlet line (9); a foaming net I (11) is disposed in front of the venturi tube; an impeller (13) is disposed in front of the foaming net I, and is rotatably connected to an impeller bracket (14); the impeller bracket is fixedly connected to the wall of the foaming cylinder; and a foaming net II (12) is fixed in front of the impeller bracket. The foam generator has a small size, a simple structure, and high foaming efficiency, and can generate fine, uniform and stable foam.
