Abstract
The utility model discloses a draught fan provided with a galvanized sheet case. The draught fan provided with the galvanized sheet case includes the case and an impeller arranged in the case. The case is composed of a rack and a galvanized sheet shell wrapping the rack. Two end faces of the case are provided with air inlets and a side face of the case is provided with an air outlet. A fan tongue composed of two fan tongue plates and disposed on the lower edge of the air outlet is arranged below the air outlet. The two fan tongue plates are connected with each other through a connection piece. The connection piece is a strip-shaped board arranged transversely to connect the two galvanized sheet boards with each other. The strip-shaped board is provided with a raised edge arranged in the middle position in the width direction and extending in the length direction. The draught fan provided with the galvanized sheet case provided by the utility model has advantages that the fan tongue is not easy to deform and air outlet pressure is high.
Description
Technical field
The utility model belongs to blower fan technical field, relates in particular to a kind of galvanized sheet casing blower fan.
Background technique
Blower fan is the critical component in ventilation equipment or ventilation system.The structure of blower fan generally includes casing and is located at the impeller in casing, has intake grill and exhaust outlet on casing.Conventionally the air outlet position at casing is provided with wind tongue, to improve air-out efficiency and noise decrease.For some large-scale blower fans, because size is larger, below exhaust outlet, there is the wind tongue that two wind hyoplastrons form edge, air port, these two wind hyoplastrons connect by a link.The blower fan of such structure in use finds, wind tongue is easily distortion under condition of high voltage, and this will have influence on the performance of blower fan.
Model utility content
For this reason, technical problem to be solved in the utility model is to provide the on-deformable galvanized sheet casing of a kind of wind tongue blower fan, the deficiency existing to overcome prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of galvanized sheet casing blower fan, comprise casing and be located at the impeller in casing, described casing consists of frame and the shell that is coated on the galvanized sheet in frame, described casing has intake grill in both ends of the surface, in side, there is exhaust outlet, below exhaust outlet, there is the wind tongue that is positioned at exhaust outlet lower limb that two wind hyoplastrons form, between described two wind hyoplastrons, by link, connect, it is characterized in that: described link is strip plate, its cross setting connects described two galvanized sheets, described strip plate has the projection of extending along its length in the neutral position of width direction stupefied.
The distracted triangle projection rib for being stamped to form of described projection.
Described strip plate is fixed on described two wind hyoplastrons by rivet.
In order further to improve the wind pressure that of blower fan, the top edge that described wind hyoplastron forms wind tongue is high, the inner low declining edge in outer end, and the top edge of two wind hyoplastrons forms the wind tongue of del.Adopt such structure, can so that air-out to centre, gather, thereby be conducive to improve the wind pressure that of blower fan.
Adopt technique scheme, it is not yielding that galvanized sheet casing blower fan of the present utility model has wind tongue, goes out the advantage that wind pressure is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and concrete enforcement, the utility model is elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the middle A-A of Fig. 1 is to sectional view.
In figure:
100-casing, 101-frame, 102-shell, 200-impeller, 300-wind hyoplastron, 301-wind tongue, 400-strip plate, 401-projection rib.
Embodiment
As shown in Figure 1, galvanized sheet casing blower fan of the present utility model, comprises casing 100 and is located at the impeller 200 in casing 100.Casing 100 consists of frame 101 and the shell 102 that is coated on the galvanized sheet in frame 101.Casing 100 has intake grill 101 in both ends of the surface, has exhaust outlet 102 in side, has the wind tongue 301 that is positioned at exhaust outlet 102 lower limbs that two symmetrical wind hyoplastrons 300 form below exhaust outlet 101.
Between two wind hyoplastrons 101, by link, connect, this link is strip plate 400, and its cross setting connects two wind hyoplastrons.Particularly, this strip plate 400 is fixed on two wind hyoplastrons 300 by rivet.
Shown in Fig. 2, strip plate 400 has the projection stupefied 401 of extending along its length in the neutral position of width direction.The triangle projection rib of this projection distracted 401 for being stamped to form.
In order further to improve the wind pressure that of blower fan, the top edge that wind hyoplastron 300 forms wind tongue is high, the inner low declining edge in outer end, and after the amalgamation of two wind hyoplastrons, the top edge of the two just forms the wind tongue of del.Adopt such structure, can so that air-out to centre, gather, thereby be conducive to improve the wind pressure that of blower fan.
By foregoing detailed description, can find out, it is not yielding that galvanized sheet casing blower fan of the present utility model has wind tongue, goes out the advantage that wind pressure is high.
Claims (4)
1. a galvanized sheet casing blower fan, comprise casing and be located at the impeller in casing, described casing consists of frame and the shell that is coated on the galvanized sheet in frame, described casing has intake grill in both ends of the surface, in side, there is exhaust outlet, below exhaust outlet, there is the wind tongue that is positioned at exhaust outlet lower limb that two wind hyoplastrons form, between described two wind hyoplastrons, by link, connect, it is characterized in that: described link is strip plate, its cross setting connects described two galvanized sheets, described strip plate has the projection of extending along its length in the neutral position of width direction stupefied.
2. galvanized sheet casing blower fan according to claim 1, is characterized in that: the distracted triangle projection rib for being stamped to form of described projection.
