Problems solved by technology
Iron sheet air ducts have a short service life in humid and corrosive medium environments, and need regular maintenance and replacement; rubber cloth air ducts are made of thermoplastic composite materials composed of rubber, cotton threads or steel wires, and their impact resistance is poor. When in use, the wind resistance is large, the ventilation rate is relatively low, and the cylinder body is easy to expand and deform, which makes the ventilation unstable; the cylinder body is made of glass fiber reinforced plastic, and the flange is made of steel. It is made into a glass fiber reinforced plastic barrel, and then the steel flange is made, and then the steel flange is fixed on the glass fiber reinforced plastic barrel. Another disadvantage of this kind of air duct is that the weight is relatively increased, and the steel flange is still easy to use during use. Corrosion phenomenon, bring safety hazard

Embodiment Construction
[0012] One-piece plexiglass steel air duct, including the cylinder body and the flange, the flange and the cylinder body are of an integrated structure, and the material is glass fiber reinforced plastic. The production is completed by the following steps:
[0013] (1) Making a flat plate: Cut the glass fiber cloth into the size of the tube body, spread the bottom glass fiber cloth on the plastic paper first, and coat the surface of the glass fiber cloth with resin, so that the glass fiber cloth is covered layer by layer to make Thickness is required, a flat plate is formed after curing, and the plate is peeled off;
[0014] (2) The flat plate is made into a cylinder: cut the flat plate according to the area requirements, roll it into a cylinder, use glass fiber cloth as a seal, coat the seal with resin, and seal it. After the seal is cured, it will become a cylinder body. ;The size and length of the seal is cut according to the size and length of the seal, the length of the s...

The invention discloses an integral organic glass fiber reinforced plastic wind cylinder which comprises a cylinder body and a flange; the invention relates to an organic glass fiber reinforced plastic wind cylinder used in underground of a mine; the flange and the cylinder body have an integrated structure and are manufactured by glass fiber reinforced plastic through the following step of manufacturing a slab, manufacturing the flange, manufacturing the outer surface of the cylinder body and drilling holes on the flange side of the solidified wind cylinder, etc., wherein in the step of manufacturing the slab, the slab is manufactured into the cylinder body. The organic glass fiber reinforced plastic wind cylinder has the advantages of light weight, high strength, corrosion resistance, long service life, simple maintenance, flame retardance, antistatic, convenient mounting, uneasy air leak, etc, has light weight and good ventilation and is in particular suitable for the underground of a mine project under the environment of having large wind amount, humidity, acidity, gas and other media.
Description
technical field [0001] The invention relates to an organic glass steel air duct used in underground mines, in particular to an integrated organic glass steel air duct, and simultaneously provides a manufacturing method of the air duct. Background technique [0002] The ventilation ducts used in underground mines are usually composed of a cylinder body and a flange. There are iron ducts, rubber cloth ducts, and ducts whose body is made of glass fiber reinforced plastic and the flange is made of steel. Iron sheet air ducts have a short service life in humid and corrosive medium environments, and need regular maintenance and replacement; rubber cloth air ducts are made of thermoplastic composite materials composed of rubber, cotton threads or steel wires, and their impact resistance is poor. When in use, the wind resistance is large, the ventilation rate is relatively low, and the cylinder body is easy to expand and deform, which makes the ventilation unstable; the cylinder bod...
