Description
Technical field
The utility model belongs to technical field of environment protection equipment, more particularly to a kind of rain-tight smoke removing roof ventilator.
Background technology
Common axial-flow roof ventilator, between suspension ring and threaded rod, threaded rod is used to support rain cap rainhat, its
Lower end is connected on air duct flange；Air duct bottom connecting bolt is connected with base；Base need to be fixed on installation base with fastener
On plinth.
In power house ventilation, roof ventilator is widely adopted.But roof ventilator roof leaking is often met in engineering practice
Situation.（1）Suspension ring, rainhat and threaded rod junction：Although adding rubber seal in rainhat and threaded rod junction
Packing ring, can prevent rainwater from laterally penetrating into, but threadingly tooth longitudinally penetrates into can not to prevent rainwater.In addition the mistake that packing ring is installed
Difference is aging with packing ring, and rubber washer herein can not effectively prevent rain leakage.Rainwater penetrates into along threaded rod, flows into
Air duct inwall, causes roof leaking.（2）Air duct and base junction：Herein should equipped with one circle caulking gum, but its roof leaking phenomenon with
（1）In phenomenon it is much like, in blower fan become apparent in the case of being horizontally mounted.（3）At foundation bolt：When raining, rain
It is to incline to fall, and rain-proof effect of the rainhat to base is again limited, it is impossible to base, particularly big bottom are sheltered from completely
Seat, the frequent out-of-flatness in its surface has the recessed phenomenon of small area.If foundation bolt is placed exactly in lower recess, lower recess ponding is just
Penetrated into along foundation bolt, if the rain proofness of cement installation foundation is bad, will also result in roof leaking.It is this roof leaking phenomenon be not in blower fan
Become apparent in the case of being horizontally mounted.
For anti-roof ventilator leaks, various methods are employed in actual installation engineering, such as in rises painting glass cement, added
Sealing filler ring, drainage trough etc. is opened, major part will spend a large amount of man power and materials in user's site operation, be operated on roof
The difficulty of construction is also increased, can only temporarily avoid roof leaking, effect of taking a long view is all undesirable.Existing blower fan is not only
Leak resistance is bad when raining, and the heat dissipation problem of motor is bad.And for the factory building with process equipment, what is had is processing
During can produce a certain amount of smog, directly arranged outwardly by blower fan, certain harm can be caused to environment.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of rain-tight smoke removing roof ventilator,
Including blast cap, threaded rod, air duct, base, suspension ring and motor, the blast cap lower section is provided with the air duct, and the blast cap top sets
There are the suspension ring, the blast cap is located between suspension ring and the threaded rod, the threaded rod is located at blast cap lower section and supports
The blast cap, the air duct bottom is fixedly connected with the base, and the motor, the rotation of the motor are provided with inside the air duct
Turn end and be connected with impeller, it is characterised in that the air duct top is connected with waterproof flange, the base sidepiece is provided with screwed hole, institute
The edge for stating base is provided with rain-proof swash plate, by gemel connection between the rain-proof swash plate and the base, the air duct top
Portion, the part below the blast cap are provided with louvre, and the air duct and the base are monolithic construction, in the air duct
Electrostatic precipitator is installed, the electrostatic precipitator is located at impeller lower section.
The waterproof flange is full welding manner with the air duct top.
The splicing seams of the waterproof flange are inclined cutout.
Bird prevention net is provided between the air duct and the blast cap.
The beneficial effects of the utility model are：Gemel connection between rain-proof swash plate and base, can adjust rain-proof swash plate
Angle, rain-proof swash plate can prevent rainwater from being flowed into from screwed hole；Screwed hole is arranged on the sidepiece of base, further prevents rain
The inflow of water；Waterproof flange seam crossing, waterproof flange and air duct inwall use full welding manner in one week, solve suspension ring, rainhat
With the roof leaking problem of threaded rod junction；Air duct and base are made and is integrated, solve the roof leaking of air duct and base junction
Problem；In addition the design of rain-proof swash plate, can effectively prevent whole roof ventilator roof leaking problem in use, and louvre has
Help shedding for motor heat, whole design improved structure it is simple, it is necessary to low cost, while substantially prolongs equipment
Service life；Electrostatic precipitator is installed in air duct, the smog that filtering workplace air contains prevents its pollution environment.

Specific embodiment
A kind of specific embodiment to utility model is explained below in conjunction with the accompanying drawings.
As shown in figure 1, the lower section of the blast cap 3 is provided with the air duct 6, the top of the blast cap 3 is provided with the suspension ring 1, described
Blast cap 3 is located between suspension ring 1 and the threaded rod 2, and the threaded rod 2 is located at the lower section of the blast cap 3 and supports the blast cap 3,
The bottom of the air duct 6 is fixedly connected with the base 7, and the motor is provided with inside the air duct 6, and the round end of the motor connects
It is connected to impeller, it is characterised in that the top of the air duct 6 is connected with waterproof flange 5, the sidepiece of the base 7 is provided with screwed hole, described
The edge of base 7 is provided with rain-proof swash plate 11, by gemel connection between the rain-proof swash plate 11 and the base 7, the wind
