Abstract
Provided is an axial flow fan for a tunnel brick kiln which comprises a shell group, an electromotor, an impeller group and a rectifier group. An air cooling chamber is arranged inside one side of the shell group, the air cooling chamber is fixedly connected with the shell group and is communicated with the outside, and the electromotor is positioned in the air cooling chamber. The impeller group is disposed on an output shaft of the electromotor, and the rectifier group is installed inside the other side of the shell group. With the electromotor arranged in the air cooling chamber, the axial flow fan tunnel for the brick kiln relies on air cooling to reduce temperature of the electromotor, thereby prolonging service life of the electromotor, and overcoming defects that a shell, an electromotor protection mode and an impeller structure of an existing fan for the tunnel brick kiln are not reasonable and poor blade streamlines lead the efficiency of the fan to be low. The axial flow fan for the tunnel brick kiln has the advantages of good air mobility, high efficiency, energy conservation, low noise, compact structure, and convenience to install and transport.
