An extraction type mine ventilation device

Abstract

This utility model discloses an extraction-type mine ventilation device, relating to the field of mining equipment technology. It includes a housing with a first filter chamber inside. A second filter chamber is connected to the exhaust side of the first filter chamber, and a centrifugal fan is connected to the exhaust side of the second filter chamber. An exhaust pipe is connected to the exhaust end of the centrifugal fan. An air inlet pipe is connected to the air inlet side of the first filter chamber. An air distribution box is fixedly installed at the bottom of the first filter chamber. The air inlet pipe is connected to the air distribution box via a connecting pipe. Multiple air distribution pipes are connected to one side of the air distribution box, and each air distribution pipe has multiple air distribution holes. The first filter chamber is filled with water covering the air distribution pipes. A filter plate is fixedly installed in the second filter chamber. This utility model achieves dust collection while preventing dust in the gas from contaminating the centrifugal fan and exhaust pipe, and also avoids environmental pollution from the discharged gas.
