Description

High-strength corrosion-resistant fireproof air pipe

Technical Field

The utility model relates to the technical field of air pipes, in particular to a high-strength corrosion-resistant fireproof air pipe.

Background

The ventilating duct installed in most of the domestic high-rise office buildings adopts a metal air duct made of galvanized plates, the existing air duct has poor heat insulation performance, so that the energy consumption generated in the ventilation process in the office buildings is high, and in order to solve the problem, more and more high-rise buildings are provided with glass magnesium air ducts made of glass magnesium plates. The glass magnesium board has good heat preservation performance and has the characteristics of high strength, corrosion resistance, flame retardance, moisture resistance and the like, but the glass magnesium air pipe has poor production quality stability, and the phenomena of air pipe cracking, peeling and the like frequently occur in use, so that the market prospect of the glass magnesium air pipe is influenced; furthermore, the air pipe is faster in use because of the air flow rate, and when the air outlet needs to be matched with the isolation net, noise is increased because of friction of air, so that normal indoor life and offices are affected, and the existing air pipe is improved, and noise generated by the air pipe is reduced.

For this reason, an improvement has been made by those skilled in the art, for example, a noise reduction duct for improving structural strength is disclosed in chinese patent No.: 201720156142.6, which comprises a pipe body, wherein a plurality of grooves which are uniformly arranged are formed on the inner wall of the pipe body; the outer side of the pipe body is provided with a heat preservation layer; a glass fiber reinforcing layer is arranged on the outer side of the heat insulating layer; reinforcing ribs are respectively clamped on four edges on the outer side of the pipe body.

However, the above solution has problems in that: (1) If the fire-proof air duct is used as a fire-proof air duct, the air duct is possibly damaged under the action of high-temperature smoke and long-term use, and thick smoke spreads everywhere after damage, so that certain potential safety hazard exists; (2) Although the strength of the air pipe is increased outside, the air flow is larger and can be pressed from inside to outside, so that the structural deformation in the air pipe can be caused in the long-term past, and the use quality of the air pipe can be further influenced; (3) The air pipe has no anti-corrosion function, and the outside of the air pipe is exposed in the air and is easy to erode, so that the service life of the air pipe can be reduced.
