Abstract
The utility model relates to a gas draining pipe for coal mining. A thin-wall steel belt is taken as a raw material; a spiral steel pipe with a reinforcing rib is processed through a spiral duct machine; a seaming weld joint is welded at a seaming joint of the spiral steel pipe; flanges are welded at two ends of the spiral steel pipe; the surfaces of the flanges and the surface of the spiral steel pipe are subjected to rust removal; and anti-flaming anti-static epoxy coatings are coated on the surfaces of the flanges and the surface of the spiral steel pipe. The demands on light weight, gas-tightness and anti-flaming property of the gas draining pipe for coal mining are met; an anticorrosive demand is also met; and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to the gas drainage under suction pipe of using in a kind of colliery, reaches gas drainage under suction pipe in light weight, air tight, etch-proof.
Background technology
At present, known gas discharge in mine pipe has: the most frequently used common steel tube, in order to guarantee pipeline certain intensity is arranged, and steel pipe must have certain thickness, and steel pipe is heavy, is not easy to construction, and is perishable; Underground mine use glass fiber reinforced plastic gas releasing pipe, underground mine use polyvinyl gas drainage under suction pipe, underground mine use steel frame polyvinyl gas drainage under suction pipe etc.; These several kinds of pipelines not only exist weight heavier, the shortcoming that construction is inconvenient, and have great potential safety hazard, when under the coal mine during breaking out of fire, these several kinds of pipelines self can burn and so receive after can emit a large amount of toxic gases.
Summary of the invention
For the shortcoming that overcomes existing gas discharge in mine pipe Heavy Weight, leaks gas, is easy to corrode, the utility model provides a kind of gas drainage under suction pipe, not only can satisfy in light weight, air tight, self incombustible requirement, and can solve etch-proof requirement.
The utility model solves the technical scheme that its technical problem adopted: the gas drainage under suction pipe that a kind of colliery is used; It is characterized in that: use the thin-walled steel band to be raw material; Seaming forming technique through Spiral ducted unit; Process the spiral steel pipe that has reinforcing rib, reinforcing rib can play the effect of gaining in strength, and can satisfy lightweight requirement; In order to satisfy the gastight requirement of gas drainage under suction pipe, with the seam welding of electric welding machine with the reinforcing rib seaming; The welding flange at the two ends of said spiral steel pipe; With the above spiral steel pipe surface derusting that has welded flange, welded the seaming weld seam, the epoxy coating of surface-coated one deck flame-retardant and anti-static installs layer protecting film additional, plays corrosiveness.
Description of drawings
The gas drainage under suction pipe constructional drawing that Fig. 1 uses in the colliery.
Description of reference numerals
1 flange;
2 spiral steel pipes;
3 seaming weld seams
The specific embodiment
In Fig. 1, the gas drainage under suction pipe that a kind of colliery is used uses the thin-walled steel band to be raw material, through the seaming forming technique of Spiral ducted unit, the thin-walled steel band is processed the spiral steel pipe 2 that has reinforcing rib; Weld through electric welding machine at 2 seaming places with spiral steel pipe, welds out seaming weld seam 3; At spiral steel pipe 2 two ends welding flanges 1, prevent to leak gas in the use of gas drainage under suction pipe negative pressure exhausting; The gas drainage under suction pipe surfaces externally and internally rust cleaning of making above comprises flange 1 surface derusting, and the epoxy coating at surfaces externally and internally coating one deck flame-retardant and anti-static of flange and spiral steel pipe plays corrosiveness.
Technique effect
The beneficial effect of the utility model is that under the abominable condition of work, the gas drainage under suction pipe satisfies the requirement of Safety of Coal Mine Production, accomplishes in light weight, air tight, anticorrosion, reduces working strength of workers simultaneously under coal mine.
Claims (2)
1. the gas drainage under suction pipe that the colliery is used is characterized in that: use the thin-walled steel band to be raw material, have the spiral steel pipe of reinforcing rib through the spiral duct machining; The seaming weld seam is welded out in spiral steel pipe lock joint place;
The welding flange at the two ends of spiral steel pipe; With said flange surface and said spiral steel pipe surface derusting;
Epoxy coating at said flange surface and said spiral steel pipe surface-coated one deck flame-retardant and anti-static.
