Abstract
An abrasion resistant bent pipe comprises an inner-side arc-shaped pipe, a middle arc-shaped pipe, an outer-side arc-shaped pipe and a detection housing, wherein all the inner-side arc-shaped pipe, the middle arc-shaped pipe and the outer-side arc-shaped pipe adopt semicircular arc-shaped pipes; the middle arc-shaped pipe is combined with the inner-side arc-shaped pipe to form a circular arc-shaped pipe, and two ends of the middle arc-shaped pipe are connected with connecting circular pipes; outer ends of two connecting circular pipes are connected with connecting flanges respectively; the outer-side arc-shaped pipe is sleeved outside the middle arc-shaped pipe, and two ends of the outer-side arc-shaped pipe are fixed by coupling bands; the detection housing is sleeved outside the abrasion resistant bend pipe to form an enclosed box body; and a pressure gauge and an ash discharging pipe are also mounted on the box body. The utility model prolongs the service life of the abrasion resistant bend pipe, reduces the consumption of the abrasion resistant bend pipe, and also can lower the maintenance cost of the spare parts and save the cost. Moreover, the utility model also can judge whether the abrasion and cracking of the abrasion resistant bend pipe occur through monitoring the pressure change, and then takes measures of repairing the abrasion resistant bend pipe in time to avoid the phenomenon that the environment is polluted by abundant dust spraying from the bend pipe after abrasion and cracking.
Description
Technical field
The utility model belongs to field of mechanical technique, can be applied to the granule medium transportation art of similar dust, coal dust in the industries such as metallurgy, electric power, cement, this bend pipe can improve the antiwear property of 90 ° of corners of conveyance conduit, and be easy to realize local replacing, reduce the abrasion-proof bent tube total consumption, design has bend pipe wearing and tearing cracking detection device on this bend pipe simultaneously, avoids bend pipe cracking back medium to leak in a large number, causes medium waste and befouling environment.
Background technique
Adopt bag-type dust at the coal gas purging system during blast furnace overhaul, realize environmental protection and energy saving.The crude-gas that comes out from blast furnace is transported to 14 dedusters, and through behind the bag-type dust, purified gas enters the purified gas house steward from dust remover roof, and dust granules is deposited in the deduster, regularly discharges from the deduster bottom.Wherein the dust of 14 dedusters divides 2 road pipelines to adopt the nitrogen about 0.46Mpa independently to be transported to 2 storage ash pipes.
Because dust is under the conveying of high pressure nitrogen, transporting velocity is easy to the wearing and tearing that ash conveying pipe is produced than higher.Find in the using process at the scene, from deduster bottom level ash conveying pipe to vertical ash conveying pipe transition with vertical more serious to the defeated grey bend pipe wearing and tearing of horizontal transition again, for this reason, field by using carbon steel add the abrasion-proof bent tube of diabase structure.Wherein outer bend pipe, anti-bend pipe adopt Q235-B material steel pipe, and wearing layer is the diabase high-abrasive material of chuck.
In use, the bend pipe of this chuck high-abrasive material structure adopts the bend pipe of Q235-B material processing to compare with integral body, and anti-wear energy is eager to excel, and life cycle is longer relatively.But, this abrasion-proof bent tube effect or not obvious of resistance to wearing, in general, the abrasion-proof bent tube life cycle of this structure of a cover was only used about 10 days.In case the wearing and tearing cracking appears in abrasion-proof bent tube, the dust granules of a large amount of high pressure is spouting, not only causes abrasion-proof bent tube to damage, and consumes the abrasion-proof bent tube spare part, and a large amount of serious dust pollution of the environment.The dust of on-the-spot wearing and tearing is carried abrasion-proof bent tube as shown in Figure 3.
Summary of the invention
The purpose of this utility model is to design a kind of abrasion-proof bent tube, adopts the more intense medial arc pipe of antiwear property in part easy to wear, adopts the structural member of common material simultaneously in the smaller place of relative wear, improves the abrasion-proof bent tube cost performance.Prolong the working life of wear-resistant pipe, reduce bend pipe consumption, can reduce the spare part maintenance cost again, save cost.And, can also judge whether abrasion-proof bent tube the wearing and tearing cracking occurs by the variation in pressure of monitoring pressure, thereby in time take the abrasion-proof bent tube reclamation activities, avoid a large amount of dust in bend pipe wearing and tearing cracking back spouting, befouling environment.
For achieving the above object, the technical solution of the utility model is,
A kind of abrasion-proof bent tube, it comprises, inboard arc pipe is the semi-circle pipe; The medial arc pipe is the semi-circle pipe, forms an arc tube with inboard arc pipe jointing, and each connects the pipe connection by one two ends; Two connect the pipe outer end and respectively connect a mounting flange; The outer arcuate pipe is the semi-circle pipe, is sheathed on the medial arc pipe outside, and it is fixing that two ends connect hoop by one.
Further, comprise that also one detects housing, be sheathed on outside the above-mentioned abrasion-proof bent tube, form a closed box, pressure gauge and ash releasing tube also are installed on this casing.
Again, described medial arc pipe is embedded in described outer arcuate inner tube wall, and the medial arc pipe adopts strong stupalith or the nanometer material of antiwear property, connects with resin or glue curing agent.
In addition, described medial arc pipe adopts the high-hardness wear-resistant liner plate, is connected in the outer arcuate inner tube wall.
Have, inboard arc pipe described in the utility model is connected pipe and is structure as a whole with two again.
Described inboard arc pipe is connected the employing of pipe and flange plate and is welded to connect with two, perhaps the integrative-structure that forms for cast inblock.
Described inboard arc pipe, medial arc pipe, outer arcuate pipe are 90 ° of arc pipes, and the abrasion-proof bent tube of formation also is 90 ° of arc pipes.
The beneficial effects of the utility model
In the abrasion-proof bent tube of this structure of the utility model, the high speed dust granules that enters into bend pipe along airflow direction mainly carries out impact wear to middle arc pipe, and compare less to other component wear of bend pipe, adopt the more intense medial arc pipe of antiwear property in part easy to wear like this, adopt the structural member of common material simultaneously in the smaller place of relative wear, improve the abrasion-proof bent tube cost performance.
The medial arc pipe is embedded in the outer arcuate pipe, constitutes wear-resistant pipe component.In the using process,, can carry out built-up welding generally speaking to the outer arcuate pipe of wear-resistant pipe and continue to use at the scene, prolong the working life of wear-resistant pipe if the wearing and tearing cracking appears in wear-resistant pipe.If wear-resistant pipe wearing and tearing cracking is more serious, can carries out independent replacing to wear-resistant pipe, and not need to change inboard arc pipe or determine whether replacing according to inboard arc pipe abrasion condition.The member that resistance to wears of abrasion-proof bent tube can be separated processing with other member like this, promptly can improve the abrasion resistance properties of 90 ° of bend pipes, reduce bend pipe consumption, can reduce the spare part maintenance cost again, save cost.
Design one cover detects housing in the abrasion-proof bent tube of this structure of the utility model, and cracked parts easy to wear in the bend pipe is sealed in case inside, and housing is equipped with Pressure testing index gauge and ash releasing tube.When the wearing and tearing cracking appears in abrasion-proof bent tube, pressure indicator is indicated to about ash conveying pipe internal high pressure nitrogen pressure 0.465Mpa by the pressure under the usual situation " 0 ", so just can reach and judge whether abrasion-proof bent tube the wearing and tearing cracking occurs by the variation in pressure of monitoring pressure index gauge, thereby in time take the abrasion-proof bent tube reclamation activities, avoid a large amount of dust in bend pipe wearing and tearing cracking back spouting, befouling environment.
