Abstract
A negative-pressure air fan with favorable daylighting performance comprises a shell, an electric motor, impellers and louvers, wherein the electric motor and the impellers are mounted in the shell; the louvers are arranged at the air outlet of the shell and connected with the shell through a louver rotating shaft; the louver rotating shaft is connected with a louver control device for controlling the rotation of the louver rotating shaft; the louver control device comprises a control rod, a linkage rod and the louvers, and the control rod is connected with the louver rotating shaft through the linkage rod; the electric motor is mounted at the corner of the shell, the impellers are arranged in the middle of the shell, and the electric motor drives the impellers to rotate through a transmission belt; and the fan blades of the impellers adopt six impellers made of aviation aluminum-magnesium alloy. The air fan has light weight and high strength due to the fan blades made of aviation aluminum-magnesium alloy; and the louvers can be pulled up and fixed through the louver control device equipped on the shell, so as to facilitate daylighting and ventilation.
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 daylighting.
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.Present negative-pressure air fan blinds all is automatic opening and closing, when negative-pressure air fan does not use, and the blinds 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, and the good negative-pressure air fan of daylighting.
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 daylighting is good, comprise housing, be installed on motor and impeller in the housing, be located at the blinds at housing exhaust outlet place, this blinds is connected with housing by the blinds rotatingshaft, this blinds rotatingshaft is connected with the blinds control gear of its rotation of control, but utilizes this device manual unlocking blinds.
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.
Described motor mounting is in the housing corner, and impeller is located at the medium position of housing, and motor rotates by the driving belt impeller.
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.
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 is provided with the blinds control gear, can live the blinds pull-up surely, is beneficial to lighting and ventilation.

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 daylighting, comprise housing 3, be installed on motor 1 and impeller 2 in the housing, be located at the blinds 4 at housing 3 exhaust outlet places, this blinds 4 is connected with housing 3 by blinds rotatingshaft 6, this blinds rotatingshaft 6 is connected with the blinds control gear 7 of its rotation of control, but utilizes this device manual unlocking blinds 4.Blinds control gear 7 comprises controlling rod 8, continuous motion stem 9 and blinds 4, and controlling rod 8 is connected with blinds 4 rotatingshafts by continuous motion stem 9.Motor 1 is installed on housing 3 corners, and impeller 2 is located at the medium position of housing 3, and motor 1 rotates by driving belt impeller 2.The six slice impellers of impeller 2 flabellums for adopting the aviation aluminum-magnesium alloy to make.
When the negative-pressure air fan that the utility model daylighting 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, then blinds 4 is opened automatically, is discharged outside the factory building by exhaust outlet, makes factory building reach aeration-cooling effect.When motor 1 was out of service, blinds 4 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 8, blinds 4 is opened, and fixedly controlling rod 8, conveniently carry out lighting and ventilation.
