Glass magnesium flat plate combined smoke gas exhaust passage

Abstract

The invention relates to a glass magnesium flat plate combined smoke gas exhaust passage with the advantages that the structure is simple and stable, the bonding of the outer part of the glass magnesium flat plate combined smoke gas exhaust passage with a brushing layer is firm, and the gas at the inside is always smooth. The glass magnesium flat plate combined smoke gas exhaust passage has the scheme that the glass magnesium flat plate combined smoke gas exhaust passage comprises a pipeline body consisting of four glass magnesium rectangular plates, wherein a fireproof long strip-shaped plate is fixedly arranged at the included angle part of the two glass magnesium rectangular plates arranged in the pipeline body, glass fiber net belts are arranged at the included angle parts of the two glass magnesium rectangular plates outside the pipeline body in a covering way for forming the sealing, flat iron covering corners are respectively arranged outside the glass fiber net belts arranged at the included angle parts of the upper, middle and lower ends of every two glass magnesium rectangular plates for reinforcement, the outer surfaces of the glass magnesium rectangular plates are subjected to sgraffito treatment, the inner surfaces of the glass magnesium rectangular plates are smooth planes, an air inlet is formed in one side wall of the upper part of the pipeline body, and a fireproof check valve is arranged at the air inlet part. The glass magnesium flat plate combined smoke gas exhaust passage has the advantages that the outer surfaces of the glass magnesium rectangular plates are made of sgraffito surfaces, so the bonding performance of the plate materials and the cement mortar can be enhanced, and the inner walls are flat and smooth, the dust accumulation in the pipe wall inside a pipeline can be avoided, the air can pass in an unblocked way, the integral performance is high, the sealing performance is good, and the stability of the pipeline is enhanced.

Description

technical field [0001] The invention relates to a smoke exhaust air channel, in particular to a glass magnesium plate combined smoke exhaust air channel. Background technique [0002] At present, the flue gas duct products made by hand made of cement on the market have simple production technology, uneven wall thickness, poor flatness, irregular shape and size, flexible impact resistance and fire resistance limit are not up to the standard requirements, and there are old-fashioned glass magnesium plates. The combination of smoke exhaust pipes is that the outer surface is too bright and the cement mortar paint layer is not easy to combine, which will make the paint layer hollow and cracked. The second is that the inner corners used are not rounded or beveled, but 15mm by 30mm fireproof slats , or the plastic fastening belt used on the outer surface of the finished flue is soft and easy to break during handling. It cannot reach the firmness of the exhaust gas flue to fix the w...

Problems solved by technology

[0002] At present, the flue gas duct products made by hand made of cement on the market have simple production technology, uneven wall thickness, poor flatness, irregular shape and size, flexible impact resistance and fire resistance limit are not up to the standard requirements, and there are old-fashioned glass magnesium plates. The combination of smoke exhaust pipes is that the outer surface is too bright and the cement mortar paint layer is not easy to combine, which will make the paint layer hollow and cracked. The second is that the inner corners used are not rounded or beveled, but 15mm by 30mm fireproof slats , or the plastic fastening belt used on the outer surface of the finished flue is soft and easy to break during handling. It cannot reach the firmness of the exhaust gas flue to fix the whole, and it is easy to break without setting fire. It leads to the cracking of the combined seam of the exhaust gas channel. Fourth, the lack of integrity will lead to the failure of flexible impact resistance, etc., resulting in serious quality and safety hazards.
