Abstract
The utility model is a gas extraction-exhaust zinc-plated spiral tube for mine which can effectively solve some problems to make the gas extraction-exhaust tube light, airtight, static and capable to bear high suction pressure. The technical scheme of the solution is that the utility model comprises a tube body and a tube seat, the tube body is made by winding up a zinc-plated belt to form a spiral structure with one side of the belt mounted on the other side, a tube seat(6) is welded with one end of the tube(4), a tube seat(1) is welded with the other end, a tube seat(2) is provided at the inside of the tube seat(1), the connections between the tube seats and the tube are welded and pasted with anti-flaming sealing gum, the existence of the zinc-plate and the mechanical clamping of the spiral make the tube body have a higher strength, a better corrosion-resistance and a better antistatic property to ensure that the safety of the mine is not threatened. The structure of connection above allows the joining of the tube seat and the tube body bear higher suction pressure in the performance. The utility model is light with a relative low price, is more convenient for transportation and construction and can effectively reduce the difficulty of constructing and improve the work efficiency.
Description
One, technical field
The utility model relates to a kind of mining gas discharging pipe, the zinc-plated volute of especially a kind of mining gas discharging that is used for drawing out methane under the coal mine.
Two, background technique
The mine selected pipeline that draws out methane is generally common welded steel pipe, PE pipe, pvc pipe or Glass Steel Tube.They tend to occur following situation in production and using process:
1, common welded steel pipe is easy to corrosion in the wet environment of mine, and this not only can shorten its working life, and the etch pit that is produced causes the gas in the pipeline to leak easily, and production threatens to mine safety; Body is relatively heavier, can cause certain difficulty to construction, and the pipeline windage is big, and labour cost is than higher, and the steel pipe cost is quite expensive;
2, Glass Steel Tube, PE pipe and pvc pipe are bigger in production link toxicity, and environment and direct labor are had direct harm; Anti-static electricity property is poor, can threaten to safety in production, and be easy to generate fracture or crack in carrying, work progress, and is imperative with innovation to the improvement with the gas extraction pipeline now.
Three, model utility content
At above-mentioned situation, the purpose of the utility model just provides the zinc-plated volute of a kind of novel mining gas discharging, can effectively solve the light weight of gas extraction pipe, structure is airtight air tight, no static and can bear the problem of high negative, the technological scheme of its solution is, the utility model is made of body and flange plate, body is formed to enclose to connect with its corresponding sides spiral interlock on one side by Galvanized Steel Strip, the body 4 one ends flange plate 6 that has been welded, the other end flange plate 1 that has been welded, flange plate 2 is equipped with in flange plate 1 inboard, be coated with flame retardant sealant after flange plate and the welding of body jointing, the existence of zinc coat and mechanical spiral interlock make body have higher intensity, rust resistance, antistatic behaviour is guaranteed can not produce threat to mine safety; Above-mentioned linkage structure makes the joint potential energy of flange plate and body bear higher operation negative pressure.Its light weight, price is relatively low, and it is more convenient to carry, construct, and can effectively reduce difficulty of construction, increases work efficiency.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another example structure schematic representation of the present utility model.
Fig. 3 is the structural representation (amplification) of the body external spiral convex tendon of the utility model structure.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By Fig. 1, shown in Figure 2, the utility model is to be made of body 4, flange plate 1,2,6, body 4 by Galvanized Steel Strip on one side 7 enclosing to connect with its corresponding sides 8 spiral interlocks and form, the body 4 one ends flange plate 6 that has been welded, the other end flange plate 1 that has been welded, flange plate 2 is equipped with in flange plate 1 inboard.In order to guarantee to use sealing, have on tube wall face and contacting point, flange plate neck end and the weld seam to be coated with all, to be coated with real flame retardant sealant layer 3.
Body 4 is outer to be had by Galvanized Steel Strip 7 to enclose to connect with its corresponding sides 8 spiral interlocks and form the spiral convex tendon 5 that protrudes to the body periphery on one side;
In order to economize in raw materials and to guarantee using effect, body 4 end outer surface are connected in circumference fillet welding mode with flange plate neck root, flange plate neck and the 6 equal diversion point spot welding of inboard wall of tube body face, and single spot welding footpath 4mm, as shown in Figure 1, Δ
4Represent three fillet welding 4mm, also can adopt Fig. 2 Placement, body screws in the flange plate that includes helical groove, body end and flange plate inwall contacting point CO
2Gas is protected the solid welding of weldering angle of circumference and is fixed on together, takes above-mentioned said which kind of form, optionally determines, its essence is equally, and all are protection domains of the present utility model.
In a word, structure of the present utility model as shown in Figure 1, the level and smooth windage in internal diameter of tube body cylndrical surface is little, the seaming convex tendon has strengthened the intensity and the toughness of body.Body is formed to enclose to connect with its corresponding sides spiral interlock on one side by Galvanized Steel Strip, flange plate covers by the fillet welding of body end outer surface circumference, flange plate neck and inboard wall of tube body face six equal diversion point point postwelding butt welded seams and is coated with flame retardant sealant and connects with body, guarantees that weld seam is air tight, the gas extraction pipeline is air tight when negative pressure 81KPa.
The level and smooth windage in internal diameter of tube body cylndrical surface shown in Figure 2 is little, and the seaming convex tendon has strengthened the intensity and the toughness of body.Body is formed to enclose to connect with its corresponding sides spiral interlock on one side by Galvanized Steel Strip, and body screws in the flange plate that includes helical groove, body end and flange plate internal face CO
2Gas is protected weldering one week of welding, and the welding back is coated with flame retardant sealant to having weld seam position, flange plate neck end and tube wall face contacting point to cover.Screw and the welding of body and flange plate makes its join strength higher.And can bear high negative, satisfy of the requirement of extraction pump fully the gas extraction pipeline.
