Abstract
The invention discloses a built-in integrated frequency conversion fan belonging to a mine fan and mainly solving the technical problems of larger occupation space, higher production cost and the like because the traditional mine fan frequency converter and the frequency converter are of a split structure. The built-in integrated frequency conversion fan is characterized in that a rear cylinder body (1) which is in an axile wire and close to one end of a front cylinder body (4) is internally provided with a frequency converter (7), the upper part of the rear cylinder (1) is provided with two wiring holes, an outlet box (2) and a control box (3) are respectively arranged in the two wiring holes and are respectively connected with the frequency converter (7); the front cylinder body (4) which is in the axile wire and close to one end of the rear cylinder body (4) is internally provided with a motor (6), and impellers (4) are arranged on a rotating shaft of the motor (6); the frequency converter (7) and the motor (6) are connected into a whole in a back-to-back manner; and the rear cylinder body (1) and the front cylinder body (4) with same diameters are fixedly connected. The built-in integrated frequency conversion fan has the advantages of compact structure, relatively low production cost and smaller occupation space, and can be widely applied to the field of various mine fans.
Description
Technical field
The present invention relates to a kind of mine ventilator, the built-in integral type blower fan of particularly a kind of frequency conversion.
Background technique
At present, the frequency variator of mine ventilator and blower fan all are split-type structurals, and it is bigger to take up room, and cost of production is higher.
Summary of the invention
The purpose of this invention is to provide a kind of compact structure, relatively low, the built-in integral type blower fan of the less frequency conversion that takes up room of cost of production.
The technical solution adopted for the present invention to solve the technical problems is: it comprises blower fan cylindrical shell and motor; In rear cylinder body 1, be positioned on the medial axis near an end of preceding cylindrical shell 4 frequency variator 7 is installed; The top of rear cylinder body 1 is provided with 2 wire connecting holes; Outlet box 2 and maneuver box 3 are installed respectively on 2 wire connecting holes, outlet box 2 and maneuver box 3 respectively with frequency variator 7; In preceding cylindrical shell 4, be positioned on the medial axis near an end of rear cylinder body 1 motor 6 is installed, mounted impeller 5 in the rotating shaft of motor 6; 6 one-tenth in frequency variator 7 and motor mode back-to-back connect into integral body; 4 one-tenth fixed connections of rear cylinder body 1 and preceding cylindrical shell that diameter is identical.Also can explosion-proof isolation shell be set in the periphery of frequency variator 7 and motor 6; The explosion-proof isolation shell of frequency variator 7 and motor 6 is fixed into integral body each other; And between the two housings inner chamber, cable hole being set, cable directly passes cable hole and is connected with motor 6 with frequency variator 7 respectively.Also can make frequency variator 7 identical, and be installed on the same axis with the external diameter of motor 6 explosion-proof isolation shells.
The invention has the beneficial effects as follows: its compact structure, cost of production be relatively low, it is less to take up room.It can be widely used in various mine ventilators field.
