Description
Technical field
The utility model relates to industrial exhaust fan fields, in particular, being related to a kind of industrial anti-dust ventilation fan device.
Background technique
Under normal conditions, indoor electrical control equipment need to be maintained at certain reasonable temperature by metallurgical electric panel room, control room
Range is spent, in the higher situation of temperature, the outside air draft of exhaust fan, to keep room temperature in controlled area charactert, smelting need to be used
The exhaust fan that golden electric panel room, control room use generallys use open type axial flow blower and carries out air draft outward, as shown in Figure 1, in Fig. 1
Label 1 is air inlet protective net, label 2 is fan, label 3 is exhaust outlet protective net, label 4 is air duct shell, when blower just
Often during operation, room air has no effect to electrical equipment toward outlet, still, to winter or needs artificially by exhaust fan
When maintenance, blower does not work, since the air inlet protective net and exhaust outlet protective net at air duct shell both ends are open types, outside
Portion's dust, which is easy to flow backward, enters electric panel room, reduces electrical equipment service life, increases equipment fault frequency.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure design conjunction
Manage, have the industrial ventilation fan device of dust reduction capability.
The technical scheme in the invention for solving the above technical problem is: a kind of industrial anti-dust ventilation fan device, including
Air duct shell and fan, the fan are located in the shell of air duct, the both ends of the air duct shell be provided with air inlet protective net and
Exhaust outlet protective net, uniformly distributed several exhaust outlets being parallel to each other, in long strip type, feature exist on the exhaust outlet protective net
In: it further include dust-proof guard, several are arranged in the dust-proof guard, and successively hinged setting exists several dust-proof guards from top to bottom
The outside of exhaust outlet protective net is corresponded with exhaust outlet；The dust-proof guard is by rotating along hinged place to exhaust outlet
Covered or released covering.
Preferably, the difference in height between the hinged place of two neighboring dust-proof guard described in the utility model is less than dust-proof guard
Height.
Preferably, dust-proof guard described in the utility model is in long strip-board shape structure.
Preferably, air duct shell described in the utility model is cubic.
Preferably, hinged place described in the utility model uses hinge.
The specific application process of the utility model are as follows: when the fan 33 is operated, wind enters air duct shell from air inlet protective net
It is interior, air pressure is then generated at the exhaust outlet of exhaust outlet protective net, since dust-proof guard is by the rotatable row of being hinged on of hinge
The outside of air port protective net, under gas pressure, dust-proof guard is lifted, and wind is discharged to outdoor from exhaust outlet；When fan stops
When operation, the air pressure at exhaust outlet disappears at this time, and dust-proof guard plays dust-proof since rotationally covering down of being self-possessed lives exhaust outlet
Effect；In addition, difference in height between the hinged place of two neighboring dust-proof guard is less than the height of dust-proof guard, can make from upper and
Under the bottom of first dust-proof guard contradict the top of second dust-proof guard, the bottom of second dust-proof guard contradicts
The top of third dust-proof guard, and so on, so that multiple dust-proof guards be made to form a shutter, fan operation
When, multiple dust-proof guards Unscrew upwards in turn carries out air draft, and when fan is out of service, multiple dust-proof guards are successively downward
It is rotating closed, the exhaust outlet of exhaust outlet protective net is covered in, dust-proof effect is played.
The utility model compared with prior art, has the following advantages that and effect: being arranged on the outside of exhaust outlet protective net more
Block dust-proof guard, muti-piece dust-proof guard forms a shutter, when fan is not run, i.e., metallurgical electric panel room, control room
When being inside not required to air draft, muti-piece dust-proof guard plays dustproof effect, and external dust is avoided to enter metallurgical electric panel room, control room, from
And certain protective effect is played to indoor equipment.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to fig. 2 to Fig. 5.
The present embodiment is a kind of industrial anti-dust ventilation fan device, including in the air duct shell 4 of cubic, fan 2 and anti-
Dirt baffle 5.Fan 2 is located in air duct shell 4, and the both ends of air duct shell 4 are provided with air inlet protective net 1 and exhaust outlet protective net
3, uniformly distributed several exhaust outlets being parallel to each other, in long strip type on exhaust outlet protective net 3.Several are arranged in dust-proof guard 5, in length
Plate structure, the outside of exhaust outlet protective net 3 is successively hingedly arranged in several dust-proof guards 5 from top to bottom, with exhaust outlet
It corresponds；Dust-proof guard 5 is covered to exhaust outlet or is released covering by rotating along hinged place 6, wherein hingedly
Place 6 uses hinge.
In the present embodiment, the difference in height D1 between the hinged place 6 of two neighboring dust-proof guard 5 is less than the height of dust-proof guard 5
Spend D2.
In the present embodiment, the specific application process of exhaust fan are as follows: when fan 2 is run, wind enters from air inlet protective net 1
In air duct shell 4, air pressure is then generated at the exhaust outlet of exhaust outlet protective net 3, since dust-proof guard 5 can be revolved by hinge
Turn the outside for being hinged on exhaust outlet protective net 3, under gas pressure, dust-proof guard 5 is lifted, and wind is discharged to room from exhaust outlet
Outside；When fan 2 is out of service, the air pressure at exhaust outlet disappears at this time, and dust-proof guard 5 lives to arrange due to rotationally covering down of being self-possessed
Air port plays dustproof effect；In addition, the difference in height D1 between the hinged place 6 of two neighboring dust-proof guard 5 is less than dust-proof guard
5 height D2 can make the bottom of top-down first dust-proof guard 5 contradict the top of second dust-proof guard 5, the
The bottom of two dust-proof guards 5 contradicts the top of third dust-proof guard 5, and so on, to make multiple 5 shapes of dust-proof guard
At a shutter, when fan 2 is run, Unscrew, progress air draft, fan 2 stop multiple dust-proof guards 5 upwards in turn
When operation, multiple dust-proof guards 5 are successively rotated down closure, cover in the exhaust outlet of exhaust outlet protective net 3, play dust-proof work
With.
In the present embodiment, muti-piece dust-proof guard 5 is set on the outside of exhaust outlet protective net 3, muti-piece dust-proof guard 5 forms one
Shutter, when fan 2 is not run, i.e., when being not required to air draft in metallurgical electric panel room, control room, muti-piece dust-proof guard 5 is played
Dustproof effect, avoids external dust from entering metallurgical electric panel room, control room, to play certain protection to indoor equipment
Effect.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different, and above content is only to the utility model structure example explanation described in this specification.
