Description
Technical field:
The utility model relates to a kind of conveying straight tube structure for delivery of fluid state material, particularly a kind of socket joint typeHigh abrasion is carried straight tube.
Background technology:
Abrasion-proof pipe is carried and has been spreaded all over the industries such as electric power, metallurgy, coal, oil, chemical industry, building materials, machinery, works as wear-resistant pipeWhile carrying the large material of grindability in road (as lime-ash, coal dust, tantalite power etc.), all there is asking of an abrasion-proof pipe quick abrasionTopic, particularly bent wear is faster, in the time carrying gas, the liquid or solid with strong corrosion in abrasion-proof pipe, exists resistance toGrind the problem that pipeline is corroded and destroy very soon. In the time that conveying in abrasion-proof pipe has the material of higher temperature, exist useThe problem that heat resisting pipe price is very expensive; And abrasion resistant composite pipeline is widely used in filling in mine material, the tantalite power of serious wearTransport with mine tailing, the abrasion resistant composite pipelines such as coal fired thermal power plant powder feeding, slagging-off, defeated ash are also most suitable.
Present domestic conveying straight tube is mainly following several: 1. general material, single material, as adopt common welded tube rawThe straight tube producing, just can complete through simple welding production, although have any intensity and toughness, because of its wearabilityPoor, be 5000-8000 cube of left and right service life, change often, thereby affected operating efficiency, increased process cost,Now substantially superseded; 2. adopt seamless steel steel pipe or No. 45 welded tubes through inwall quenching heat treatment, to increase its wearabilityCan, now quenching pipe can improve ten thousand to 2.5 ten thousand cubes of left and right of delivering concrete amount to 2, and to have obtained market wide with economic and practicalGeneral utilization; 3. quote two-layer compound straight tube, inner tube material is through hardening steel alloy, and outer tube material is low-carbon alloy steel, and two ends haveAdpting flange, is inlaid with wear-resistant sleeve in flange, shelf life is greatly about 40,000 to 4.5 ten thousand cubes of left and right, but this kind of two-layer compound is straightThere is following defect in pipe: the composite force of outer tube and inner tube a little less than, in pumping procedure, occur that after plugging, operating personnel generally takeDischarge end is taken apart, carry out comb by pump concrete or water, but inner tube is very easily rushed out in this process.
At present, in the disclosed patent CN105003758A of Chinese patent literature, disclose the automobile-used height of a kind of concrete pump and closedGold is wear-resisting
Two-layer compound straight tube, it comprises outer tube, inner tube and vibration-absorptive material, described inner tube is urged in outer tube, described outer tubeAnd between inner tube, be provided with vibration-absorptive material, the material that described vibration-absorptive material adopts is one of EVA, PE, CR, PU foam, PORONKind or several; This composite straight pipe than before concrete mixer straight tube wearability increase, if but consider actual manufactureThe impact of condition (longer inner tube be difficult to produce in the time of casting and cost higher), simultaneously can be because inner tube is longer, outside being urged toIn pipe time, also may cause the damage of inner tube even to damage; Also need to consider that vibration-absorptive material bears feelings in high strength environmentCondition.
At present, in the disclosed patent CN202302357U of Chinese patent literature, a kind of wear-resisting ceramic composite straight pipe is disclosed,Comprise the body from inside to outside being formed by wear-resistant ceramic layer, glue bond layer and metallic matrix layer, wear-resistant ceramic layer and metallic matrixBetween layer, connect by glue bond layer, it is characterized in that: the head and the tail two ends of metallic matrix layer do not have wear-resistant ceramic layer to cover; This is straightPipe exist equally actual impact of creating conditions (longer inner tube when casting be difficult to produce and cost higher).
At present, in the disclosed patent CN202452011U of Chinese patent literature, a kind of straight tube and concrete conveyance are disclosedIf
Standby; This straight tube comprises composite straight pipe and is connected in the first flange and the second flange composite straight pipe of the composite straight pipe mouth of pipeComprise outer tube and inner tube; The first flange has been embedded in the first wear-resistant sleeve, and the second flange has been embedded in the second wear-resistant sleeve; The second flangeInner side be provided with a recess, the inner side of the second wear-resistant sleeve is provided with a boss that can match with recess, and composite straight pipeEnd compresses this boss, and boss is fixed in recess; Though propose in this straight tube to prevent the de-of anti-wearing liner by mechanical interlockedFall and inner tube is gone out, but owing between outer tube and inner tube being directly contact and without any vibration-absorptive material, meeting in high strength environmentThere is both mutual impacts, pipe is caused to damage.
