Description
Technical field
The utility model relates to a kind of industrial premises ventilation equipment, especially relates to the good negative-pressure air fan of a kind of dust discharge.
Background technique
Negative-pressure air fan is the latest type of ventilator, belongs to axial-flow blower, is referred to as negative-pressure air fan because being mainly used in the aeration-cooling engineering of negative pressure type.The aeration-cooling engineering of negative pressure type comprises the implication of the ventilation and two aspects that lower the temperature, and ventilation and cooling problem solve simultaneously.Negative-pressure air fan has characteristics characteristics such as super large air channel, super large fan blade diameter, super large exhaust air rate, super low energy consumption, the slow-speed of revolution, low noise.The characteristics of negative-pressure air fan have also determined the bulky, heavy of it, so that accumulate dust at the flabellum seat easily, clean inconvenience, influence outward appearance; When blower fan does not use, the flabellum closure, factory building daylighting is poor.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of guarantee to ventilate and cooling-down effect in, in light weight, intensity is high, daylighting good, attractive in appearance, and the good negative-pressure air fan of dust discharge.
For solving the problems of the technologies described above, the technical solution of the utility model is: the negative-pressure air fan that a kind of dust discharge is good, comprise housing, impeller and be used for the motor that drives impeller is rotated, this housing middle part is provided with a through hole, described impeller is located in the through hole, and through hole is provided with flange near the edge of intake grill one end, and flange is recessed to exhaust outlet, it is outdoor to make things convenient for dust to discharge through flabellum, blinds, can not accumulate on the flabellum seat.
Described housing exhaust outlet is provided with blinds, and this blinds is connected with housing by rotatingshaft, and intake grill is provided with protection net, plays windproof, dustproof, rainproof effect.
Described blinds rotatingshaft is connected with the blinds control gear of its rotation of control, but the manual unlocking blinds when not moving the good negative-pressure air fan of dust discharge, makes things convenient for lighting and ventilation.
Described blinds control gear comprises controlling rod, continuous motion stem and blinds, and controlling rod is connected with the blinds rotatingshaft by continuous motion stem.
The six slice impellers of described impeller flabellum for adopting the aviation aluminum-magnesium alloy to make, in light weight, intensity is high, good toughness.
Described motor mounting is in the housing corner, and motor is by the rotation of driving mechanism impeller.
Described driving mechanism comprises the belt pulley that is installed in impeller base and motor output shaft respectively and is connected in belt composition between two belt pulleys.
Compared with prior art, the utility model is owing to adopt the flabellum of aviation aluminum-magnesium alloy, and blower fan is in light weight, intensity is high; Housing through-hole is provided with flange, is beneficial to dust and discharges outdoor; Housing is provided with the blinds control gear, can live the blinds pull-up surely, is beneficial to daylighting.

Fig. 2 is each parts broken away view of the utility model;
Fig. 3 is the utility model exhaust outlet front elevation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the good negative-pressure air fan of a kind of dust discharge, comprise housing 3, impeller 2 and be used for the motor 1 that drives impeller is rotated, this housing middle part is provided with a through hole 14, described impeller 2 is located in the through hole 14, through hole 14 is provided with flange 9 near the edge of intake grill one end, and flange 9 is recessed to exhaust outlet.Housing 3 exhaust outlets are provided with blinds 7, and this blinds 7 is connected with housing 3 by blinds rotatingshaft 10, and intake grill is provided with protection net 8.The six slice impellers of impeller 2 flabellums for adopting the aviation aluminum-magnesium alloy to make, in light weight, intensity is high, good toughness.Motor 1 is installed on housing 3 corners, and motor 1 rotates by driving mechanism impeller 2.Driving mechanism comprises the belt pulley 51,52 that is installed in impeller base 4 and motor output shaft respectively and is connected in belt composition 5 between two belt pulleys 51,52.
As shown in Figure 1 and Figure 2, blinds rotatingshaft 10 is connected with the blinds control gear 11 of its rotation of control, but manual unlocking blinds 7.Blinds control gear 11 comprises controlling rod 12, continuous motion stem 13 and blinds 7, and controlling rod 12 is connected with blinds rotatingshaft 10 by continuous motion stem 13.
When the negative-pressure air fan that the utility model dust discharge is good was worked, motor 1 energising was rotated, and motor 1 is by the rotation of driving mechanism impeller 2, wind enters from intake grill through protection net 8, then blinds 7 is opened automatically, is discharged outside the factory building by exhaust outlet, makes factory building reach aeration-cooling effect; Simultaneously, when dust entered intake grill along with wind, because flange 9 is recessed to exhaust outlet, dust can or not accumulate in the intake grill place along with wind is discharged exhaust outlet yet.When motor 1 was out of service, blinds 7 was closed automatically, and blower fan quits work.When the factory building temperature is not high, when not needing to start blower fan and lowering the temperature, can pull down controlling rod 12, blinds 7 is opened, and fixedly controlling rod 12, conveniently carry out lighting and ventilation.
