Abstract
The utility model relates to an induced draft fan with a dust proof cover, which solves the problem of the prior induced draft fan that a large amount of sewage such as coal ash, dust and oil smoke, present in the coal smoke results into lubrication failure of an electric machine rotary shaft bearing of the induced draft fan and furthermore inability of rotation or damage to shorten the service life of the induced draft fan and the electric machine rotary shaft bearing and the maintenance cost of the user is increased. The electric machine of the induced draft fan is mounted on an upper end surface of an electric machine mounting tray and the electric machine mounting tray is horizontally fixed on the bracket of the electric machine and a round hole is arranged in the center of the electric machine mounting tray; the rotary shaft of the electric machine passes through the round hole in the center of the electric machine mounting tray to be fixedly connected with the rotary shaft of the blade and a blast cap is arranged at the top end of the electric machine bracket and just above the electric machine; the dust proof cover is fixed on the lower end surface of the electric machine mounting tray and one round hole is arranged in the center of the dust proof cover; the round hole in the center of the dust proof cover is cooperated with the rotary shaft clearance of the electric machine. The induced draft fan has advantages of long service life and low maintenance cost.
Description
Technical field
The utility model relates to a kind of induced draught fan.
Background technique
Some regional warmings of northern China still can use stove with cooking; for the good combustion that guarantees stove just need install induced draught fan additional on chimney; existing induced draught fan is installed in the place, chimney top on roof; the working environment very severe; cause the lubrication failure of id-motor shaft bearing through regular meeting owing to be mingled with dirts such as a large amount of coal ash, dust and oil smoke in the coal smoke; can not rotate or the generation of fault such as damage; seriously shorten the working life of induced draught fan and machine shaft bearing, increased user's maintenance cost.
The model utility content
The utility model causes the lubrication failure of id-motor shaft bearing in order to solve existing induced draught fan owing to be mingled with dirts such as a large amount of coal ash, dust and oil smoke in the coal smoke, can not rotate or damage and shortened working life of induced draught fan and machine shaft bearing, increase the problem of user's maintenance cost, and proposed to have the induced draught fan of dust-proof cover.
The induced draught fan that has dust-proof cover, it comprises id-motor, fan blade, electric machine support, motor tray and blast cap; Id-motor is installed on the upper-end surface of motor tray, described motor tray is horizontally fixed on the electric machine support, the center of motor tray is provided with circular hole, the circular hole that motor tray center is passed in the rotating shaft of id-motor is fixedlyed connected with the rotating shaft of fan blade, blast cap is installed in the top of electric machine support, blast cap be positioned at id-motor directly over; It also comprises dust-proof cover, on the lower end surface of the fixing installing of described dust-proof cover motor tray, dust-proof cover be positioned at id-motor 1 under, the dust cover centers place is provided with a circular hole, the circular hole at described dust cover centers place and the rotating shaft Spielpassung of id-motor.
The induced draught fan that has dust-proof cover described in the utility model has long service life, the advantage that maintenance cost is low.Add dust-proof cover 6 in motor tray 4 lower end surfaces, increased and advanced cigarette Qu Lu, can significantly reduce the dirt such as coal ash, dust that enters id-motor bearing and id-motor inside by slit between id-motor 1 rotating shaft and id-motor 1 housing, prolong the working life of id-motor 1 and id-motor bearing, greatly reduced user's maintenance cost.It can be widely used in the various occasions that need use induced draught fan in the dust pollution serious environmental.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
