Plant air duct structure coated with fireproof cotton

Abstract

The utility model belongs to the technical field of air pipes, and particularly relates to a workshop air pipe structure coated with fireproof cotton, which comprises an air pipe body, connecting flanges are connected to the surfaces of the two ends of the air pipe body, a first shell is connected to the surface of the top of the air pipe body, and the fireproof cotton is connected to the surface of the outer side of the first shell. A positioning groove is formed in the bottom surface of the first shell, and a positioning block is connected to the inner side surface of the positioning groove. The first shell, the second shell, the fireproof cotton, the positioning grooves, the positioning blocks and the bolts are matched with one another, so that the first shell and the second shell can be installed on the outer side of the air pipe body, the outer side of the air pipe body is wrapped and covered with the fireproof cotton, the fireproof performance of the air pipe is improved, and the situation that the air pipe is prone to being damaged during open fire burning is avoided; and secondly, the sound-absorbing cotton is adhered to the inner wall of the air pipe, so that noise generated when the air pipe is used can be weakened, the noise reduction performance of the air pipe is improved, and the influence on workshop workers caused by too large noise generated when the air pipe is used is avoided.
