Embodiment 1

[0011] Embodiment 1, the two ends of the fan channel 9 of the present invention are respectively provided with connecting flanges 1 matching with the fan or the air channel, and an explosion-proof control chamber 4 is provided on the outer wall that is close to and surrounds the fan channel 9, In the explosion-proof control chamber 4, the electrical component 5 of the frequency converter is installed close to the outer wall of the fan flow channel 9, so that the electrical component 5 of the frequency converter can use the air flowing in the fan flow channel to dissipate heat, and the heat dissipation area is large, which can effectively dissipate heat. . The flameproof control chamber 4 is provided with a wiring port 2 and a communication and control line connection port 8 , and a display window 6 and an operating button 7 may also be provided on the flameproof control chamber 4 . At the same time, the space of the explosion-proof control chamber 4 is relatively large, and th...

Embodiment 2

[0012] Embodiment 2, the present invention can also be respectively provided with explosion-proof connection cavity 3 and explosion-proof control cavity 4 on the outer wall close to fan flow channel 9, in order to be more conducive to the classified installation and maintenance of components and parts, in the explosion-proof connection cavity 3 The wiring port 2 and the communication and control line connection port 8 are arranged on the top, and the electrical components 5 of the frequency converter are installed in the explosion-proof control chamber 4 close to the outer wall of the fan flow channel 9 . All the other are with embodiment 1, refer to figure 1 and figure 2 .

Abstract

The invention relates to a special external transducer speeder for mine ventilator. The invention mainly solves the technical problem that the existing fan transducer speeder is poor in heat dissipation effect. The invention has the technical scheme that: the two ends of a fan runner (9) are respectively provided with a connecting flange (1), the outer wall tightly close to the fan runner (9) is respectively provided with an explosion suppression connecting line cavity (3) and an explosion suppression control cavity (4), the explosion suppression control cavity (4) is provided with a connecting port (2) and a communication and control line connection port (8), the outer wall tightly close to the fan runner (9) in the explosion suppression control cavity (4) is provided with a transducer electric element (5); and a display window (6) and a control button (7) also can be arranged on the explosion suppression control cavity (4). The transducer speeder electric element is arranged at the outside of the runner wall, the fan runner is utilized for heat dissipation, heat dissipation area is large, thus not only effectively solving the heating problem of transducer speeder power element but also being convenient for installation, debugging and maintenance, thereby improving working stability and reliability. The invention can be widely applied to control on devices such as undergroundfan, local fan and the like.
