Description
Technical field
A kind of Wear-resistant double-layered straight tube structure for trandfer fluid state material is the utility model is related to, it is particularly a kind of to use
In the heterogeneous segmented high abrasion bilayer straight tube of concrete conveyance.
Background technology
Abrasion-proof pipe is conveyed throughout industries such as electric power, metallurgy, coal, oil, chemical industry, building materials, machineries, works as wear-resistant pipe
When the big material of grindability is conveyed in road (such as lime-ash, coal dust, tantalite power), all asking in the presence of abrasion-proof pipe quick abrasion
Topic, when gas of the conveying with strong corrosion, liquid or solid in abrasion-proof pipe, abrasion-proof pipe be present and be corroded and break quickly
Bad the problem of；When conveying has the material of higher temperature in abrasion-proof pipe, there is sufficiently expensive using heat resisting pipe price
The problem of；And the filling in mine material, tantalite power and mine tailing that abrasion resistant composite pipeline is widely used in serious wear transport, coal fired thermal power plant
The abrasion resistant composite pipelines such as powder feeding, slagging-off, defeated ash are also most suitable.
Present domestic concrete mixer Wear-resistant double-layered straight tube is mainly following several：1. general material, single material, are such as adopted
With the straight tube of common Welded tube production, completed by simple welding production can, although having the intensity and toughness of a bit,
Because its wearability is poor, service life is 5000-8000 cubes or so, is changed often, so as to have impact on operating efficiency, increase
Process cost, through eliminating substantially；2. inwall quenching heat treatment is passed through using seamless steel steel pipe or steel alloy welded tube, to increase
Add its anti-wear performance, present quenching pipe can improve to 20,000 to 2.5 ten thousand cubes or so of delivering concrete amount, be obtained with economic and practical
Market has been arrived widely to utilize；3. quoting two-layer compound straight tube, inner tube material is through hardening steel alloy, and outer tube material is low-carbon alloy
There is adpting flange at steel, both ends, wear-resistant sleeve are inlaid with flange, shelf life is about at 40,000 to 4.5 ten thousand cubes or so, but this kind
Following defect be present in two-layer compound straight tube：The composite force of outer tube and inner tube is weaker, after there is plugging in pumping procedure, operator
General take of member takes discharge end apart, carries out comb by pump concrete or water, but inner tube is easily rushed in the process
Go out.
At present, in Chinese patent CN105003758A, a kind of automobile-used high alloy wear-resistance two-layer compound of concrete pump is disclosed
Straight tube, it includes outer tube, inner tube and vibration-absorptive material, and said inner tube is urged in outer tube, is provided between the outer tube and inner tube
Vibration-absorptive material, the material that the vibration-absorptive material uses are EVA, PE, CR, PU foam, PORON one or more；The composite straight
Pipe increased than former concrete mixer straight tube wearability, but if considering the influence of actual manufacturing condition (in longer
Pipe is difficult production in casting and cost is higher), while can be longer due to inner tube, it be able to may also be caused when being urged in outer tube
The damage of inner tube even damages；It is also contemplated that vibration-absorptive material bears situation in high intensity environment.
At present, in Chinese patent CN202302357U, a kind of wear-resisting ceramic composite straight pipe is disclosed, including by wear-resistant ceramic
The body that layer, glue bonding layer and metallic base layer form from inside to outside, by gluing between wear-resistant ceramic layer and metallic base layer
Tie layer connection, it is characterised in that：The head and the tail both ends of metallic base layer do not have the covering of wear-resistant ceramic layer；The straight tube equally exists reality
The influence (ceramic layer in the longer inner tube complex operation when bonding, it is difficult to produce) of manufacturing condition.
At present, in Chinese patent CN202452011U, a kind of straight tube and concrete conveying equipment are disclosed；The straight tube includes
Composite straight pipe and the first flange and second flange for being connected to the composite straight pipe mouth of pipe, composite straight pipe include outer tube and inner tube；First
Flange has been embedded in the first wear-resistant sleeve, and second flange has been embedded in the second wear-resistant sleeve；A recess is provided with the inside of second flange,
A boss that can be engaged with recess is provided with the inside of second wear-resistant sleeve, and composite straight pipe end compresses the boss, makes convex
Platform is fixed in recess；Though in this straight tube propose by it is mechanical interlocked prevent anti-wearing liner come off and inner tube is gone out, due to
It is directly to contact between outer tube and inner tube, there can be both mutual impacts in high intensity environment, pipe is caused to damage.
In addition, it has been found that the degree of wear of the abrasion-proof pipe within porch, especially porch 200mm is tight
It is great to be also seriously more than exit inside pipeline, and the abrasion in exit is also greater than inside pipeline, and existing pipeline
Design is all unitary design, therefore often causes whole pipeline to be scrapped because of being damaged at tube inlet.
