Description

A kind of split-type flame retardant glass fiber reinforced plastic air duct

Technical field

The utility model relates to flame retardant glass fiber reinforced plastic air duct technical field, specially a kind of split-type flame retardant glass fiber reinforced plastic air duct.

Background technique

The air duct of Construction of Silo ventilation at present mainly include the following types:

1, serve as a contrast hoop formula colloid light air cylinder: this air duct advantage is cheap, convenient transportation, the disadvantage is that connector combination is not tight It is close, it is easy to leak out, windage is big, blows out and is easy to be blown up by slungshot.

2, double-wall corrugated pipe instead of air duct use: advantage be it is cheap, material is durable, and windage is smaller.The disadvantage is that Pipe fitting combination imprecision, is easy to leak out, and volume is big, and transport is inconvenient, and transportation cost is high, and material is not fire-retardant, does not meet regulation and wants It asks.

3, whole glass steel air duct: for whole glass steel air duct in Zhong Meige shaft building company using relatively broad, advantage is wind Hinder small, material is fire-retardant, durable.Disadvantage, volume is big, and transport is inconvenient, and transportation cost is high.

By the advantage and disadvantage for analyzing the above air duct, it is believed that using effect in three of the above air duct is it is still further preferred that glass reinforced plastic Air duct, but since its volume is big, occupied space is big, and transport is inconvenient when causing air duct that need to forget about it the recycling of other building sites, transport At high cost, transport is not taken up space, can in high volume be transported it is most convenient that colloid light air cylinder, capable of expansion and contraction, can either with or without one kind Reach the air duct of good using effect and convenient transportation.

(3) beneficial effect

The utility model provides a kind of split-type flame retardant glass fiber reinforced plastic air duct.Have it is following the utility model has the advantages that

The utility model improves traditional air duct, and whole glass steel air duct body is cutd open into two one side of something, lower air duct With upper air duct, lower air duct and upper air duct are designed to flange pattern, pass through the second sealant layer solution sealing problem between flange.

Detachable glass fiber reinforced plastic wind tube is detachable due to realizing end flanges, side flange, by whole glass steel air duct Body cuts open into two one side of something, lower air duct and upper air duct, so that half of air duct, can in transport after realizing air duct splitting into two halves Up pile up from level to level, greatly saved transport space and place and stacked space, can in high volume transport, change in the past due to Whole glass steel air duct volume is big, and transport occupied space is big, and transportation cost is high, can not achieve the shortcomings that high-volume is transported.To The quantity of transport can be increased.

Detachable glass fiber reinforced plastic wind tube is either stored or is transported, and space is all greatly saved, for example, compartment 12.6m*2.4m*1.4m(long * wide * high) transport a collection of diameter phi 700mm, 6m long air duct, if Integral glass steel air duct or Double-wall corrugated pipe air duct, a coastiong can only at most transport 12 section entirety air ducts, it is assumed that primary every cartage of transporting for long-distance is 5000 Member, monoblock type air duct, which transports 300 section air ducts, needs 125000 yuan of freight charges, but if being detachable air duct, by the way that air duct is whole It splits into two, then two end flanges are removed, realize half of air duct successively can up pile up from level to level, then a coastiong can To load onto 600 section one side of something air ducts, 300 section entirety air ducts can once be transported by being equivalent to, and freight charges are equally 5000 yuan, compare monoblock type The transport of air duct can fill 288 section air ducts more, 24 times of entrucking capacity boost, be compared using split-type glass fiber reinforced plastic wind tube entrucking transport Same amount of monoblock type air duct can once save 130000 yuan of freight charges, and transportation cost substantially reduces.

In mine construction, a work shaft construction is generally 1 to two years, equipment after Practical Completion, turnover Material, which transfers to sundry item again, to be continued to construct, and detachable glass fiber reinforced plastic wind tube is mainly used in Construction of Silo, is guaranteeing that its is good It while good ventilation effect, solves the problems, such as that transportation cost is high, realizes being used repeatedly for material, therefore have Have wide practical use, therefore there is preferable promotion prospect.
