Abstract
The invention discloses a kind of architectural engineering air return systems, it is characterized in that, including L-type ventilation shaft (1), the exhaust fan (2) internal in L-type ventilation shaft (1) is set, the rain insensitive device on the outlet air end of L-type ventilation shaft (1), and the air-returning device being arranged below L-type ventilation shaft (1) are mounted on by support rod (3)；Top cover of the invention is inverted " V " font, and upper end is provided with gutter, can be very good to drain rainwater when rainy；Simultaneously, caping, which covers, is provided with gas vent, and top cover is internally located at the flashing board that " V " type is provided with below gas vent, which indoor air can be discharged, and flashing board can then prevent rainwater from entering the room, and keep the waterproof performance of aeration structure of the invention more preferable.After indoor air, which leads to a few pipelines from L-type, to be discharged, due to suction function, outdoor air then enters interior from backwind tube, to remain indoor with fresh air.
Description
Technical field
The present invention relates to field of ventilation equipment, in particular to a kind of architectural engineering air return systems.
Background technique
Setting ventilation device is usually required in the buildings such as some workshops, workshop at present to divulge information to indoor air circulation, with
Maintain room air pure and fresh.However traditional its waterproof performance of air device is bad, is unable to satisfy demand.
Summary of the invention
The defect that it is an object of the invention to overcome traditional its waterproof performance of air device bad, provides one kind and builds
Build engineering air return system.
The purpose of the invention is achieved by the following technical solution: a kind of architectural engineering air return system, including L-type ventilation duct
The exhaust fan inside L-type ventilation shaft is arranged in road, the rain-proof being mounted on the outlet air end of L-type ventilation shaft by support rod
Device, and the air-returning device below L-type ventilation shaft is set；The air-returning device includes backwind tube, is arranged in backwind tube
Internal filter plate and air dryer.
Shutter is provided at the air outlet of the backwind tube.
The rain insensitive device includes the top cover in inverted " V " font, is provided with top cover lower end gutter.
It is provided with gas vent on the top cover, inside the top cover and is located at below gas vent drainage arrangement is installed；Institute
The both ends of drainage arrangement are stated through top cover.
The drainage arrangement is V-shaped flashing board, and the both sides of the flashing board are provided with along extending portion.
The present invention compared with the prior art, has the following advantages that and the utility model has the advantages that top cover of the invention is inverted " V " font,
And upper end is provided with gutter, can be very good to drain rainwater when rainy；Meanwhile caping covers and is provided with gas vent, and
Top cover is internally located at the flashing board that " V " type is provided with below gas vent, which indoor air can be discharged, and rain-proof
Plate can then prevent rainwater from entering the room, and keep the waterproof performance of aeration structure of the invention more preferable.When indoor air is logical from L-type
After a few pipeline discharges, due to suction function, outdoor air then enters interior from backwind tube, to maintain indoor air clear
Newly.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
The present invention is described in further detail below with reference to embodiment, but embodiments of the present invention are not limited to
This.
Embodiment
As shown in Figure 1, architectural engineering air return system of the invention, including L-type ventilation shaft 1, it is arranged in L-type ventilation shaft
Exhaust fan 2 inside 1, the rain insensitive device being mounted on by support rod 3 on the outlet air end of L-type ventilation shaft 1, and be arranged in L
The air-returning device of 1 lower section of type ventilation shaft.
Specifically, the air intake of the L-type ventilation shaft 1 is located at interior, outlet air end is then located outside, air outlet court
On.Exhaust fan 2 is mounted in the L-type ventilation shaft 1 by bolt, and is located at its air intake side, and support rod 3 then passes through welding
Mode is connect with L-type ventilation shaft 1.
Due to the L-type ventilation shaft 1 air outlet upward, as shown in Figure 1, the rain insensitive device includes in inverted " V " font
Top cover 5 is provided with 5 lower end gutter 4 of top cover.That is one end of the support rod 3 is welded on the outside of L-type ventilation shaft 1, another
End is then welded on top cover 5, and forms air-out passage between top cover 5 and L-type ventilation shaft 1.
As a preference, being provided with gas vent 6 on the top cover 5, installed inside the top cover 5 and below gas vent 6
There is drainage arrangement, top cover 5 is run through at the both ends of the drainage arrangement.Specifically, the drainage arrangement is the flashing board of V-shaped setting
7.When rainwater enters in top cover 5 from gas vent 6, rainwater can be dropped on flashing board 7, since the both ends of lid flashing board 7 are passed through
Top cover 5 is worn, therefore drop into the rainwater on flashing board 7 top cover 5 can be discharged along rain-proof 7, rainwater is avoided to enter interior.
In addition, the both sides of the flashing board 7 are provided with along extending portion 8, so as to preferably catch the rain entered in top cover
Water.
When work, indoor air is pumped into L-type ventilation shaft 1 by exhaust fan 2, and air is from the outlet of L-type ventilation shaft 1
The lower section that flashing board 7 is reached after discharge, due to the barrier effect of flashing board 7, air a part is from top cover and L-type ventilation shaft 1
Between air-out passage discharge, it is a part of then pass through the top that channel between top cover and flashing board 7 is discharged to flashing board 7, and from
Gas vent 6 is discharged.
In addition, the air-returning device includes the backwind tube 9 being arranged in below L-type ventilation shaft 1, return air is mounted on by bolt
Filter plate 10 and air dryer 12 inside pipe 9, and it is mounted on the shutter 11 at the air outlet of backwind tube 9.
After indoor air leads to a few pipeline discharge outdoors from L-type, due to suction function, outdoor air is then from backwind tube
9 enter interior, and air remains indoor with fresh air after the filtering of filter plate 10 in the process, while air is through overdrying
Make to enter indoor air holding drying after dry device 12.
As described above, the present invention can be realized well.
