Problems solved by technology

[0004] Specifically, on the one hand, only an exhaust fan is installed at the air outlet, so that the sound insulation and noise reduction effect is not very good, and the outdoor noise is easily transmitted to the room through the corresponding air outlet, which will cause greater noise pollution. On the other hand, the air outlet is only equipped with an exhaust fan, and the outdoor wind and rain are easily splashed into the room through the corresponding air outlet. It is easy to fall to the corresponding air outlet and block the corresponding air outlet. At the same time, due to the requirement of air volume, the size of the exhaust fan is generally large, which requires that the diameter of the air outlet should be opened to about 200mm. , it will cause great damage to the exterior wall of the building, causing it to have the risk of cracking, resulting in poor stability, and making the excavation of the exhaust outlet a large amount of work, which makes the installation of the exhaust fan time-consuming and laborious, and the required ventilation The machine is directly installed at the corresponding air outlet, which makes it easy to be squeezed and deformed by the deformed building exterior wall, resulting in a short service life

Abstract

The invention discloses a primary air system pipeline device convenient to mount. The device comprises an exhaust assembly and an air inlet assembly; the exhaust assembly comprises an exhaust pipeline, a first-stage exhaust fan, a noise reduction air guide cylinder A and an exhaust rough obstruction net; the air inlet assembly comprises an air inlet pipeline, a first-stage exhaust fan, a noise reduction air guide cylinder B and an air inlet fine obstruction net; according to the beneficial effects, a passing opening is formed in the building wall, the first-stage exhaust fan, the noise reduction air guide cylinder A and the exhaust rough obstruction net are assembled to the exhaust pipeline, the first-stage exhaust fan, the noise reduction air guide cylinder B and the air inlet fine obstruction net are assembled to the air inlet pipeline, the exhaust pipeline is inserted into the building wall passing opening, the air inlet pipeline is inserted into the building wall passing opening, the device is rapid and convenient to mount, the noise reduction air guide cylinder A and the noise reduction air guide cylinder B have a certain rain sheltering effect, the noise reduction effect andthe air guide effect, flying birds can be effectively prevented from inhabiting, objects like fallen leaves outside the building wall can be effectively obstructed from floating in, and the device ishigh in practicability and good in use effect.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a pipe device for fresh air systems that is easy to install. Background technique [0002] In existing major buildings, an air outlet with a diameter of about 200mm is often provided on the outer wall of the building, and fastening bolts and other fixings are driven into the wall at the corresponding air outlet to install a The exhaust fan that extracts the indoor air is used to build a fresh air system to speed up the flow and renewal of indoor air. [0003] For the above approach, although it is widely used, it still has certain defects and deficiencies. [0004] Specifically, on the one hand, only an exhaust fan is installed at the air outlet, so that the sound insulation and noise reduction effect is not very good, and the outdoor noise is easily transmitted to the room through the corresponding air outlet, which will cause greater noise pollution. On the other ha...
