Technical field
A kind of surface derusting device for steel tubes is the utility model is related to, more particularly to a kind of line Pipe surface derusting device.
Background technology
With the continuous development of China's economy country greatly develops energy industry, long oil/gas pipe line is energy safeguard
Important way, during oil/gas pipe line anticorrosive construction, steel tube surface processing is to determine the key of pipeline corrosion protection service life
One of factor, it be anticorrosive coat with steel pipe can strong bonded premise.Verified through research institution, the life-span of anticorrosive coat, which removes, to be depended on
In outside the factors such as coat type, coating quality and construction environment, the influence of the surface treatment of steel pipe to the anticorrosive coat life-span accounts for
50%, therefore, it should constantly explore and summarize, update steel pipe table in strict accordance with requirement of the anticorrosive coat specification to steel tube surface
Face processing method.
In order to improve the life-span of oil/gas pipe, to be generally surface-treated, in favor of steel pipe and the firm knot of anticorrosive coat
Close.Common processing mode has：Cleaning, toolrust-removal, pickling, the spray class of impeller blasting four.Conventional acid dip pickle is with regard to simple
One descaling bath, therefore, conventional pickling soak the oxide skin and rust for washing surface off by using hydrochloric acid for a long time, and alkali neutralizes,
Then the descaling bath pickling processes that upper tinuous production is carried out again, then alkali neutralize, and whole process pickling twice, neutralize, make twice
Into a large amount of sour wastes and discharge, it is unfavorable for the protection of environment, cost of idleness.In addition, conventional acid dip pickle, it is impossible to preferably
The greasy dirt of steel tube surface is removed, the steel tube surface after pickling processes still there are a small amount of greasy residues.
The content of the invention
The purpose of this utility model is a kind of line Pipe surface derusting device, by online to the direct pickling of steel pipe,
Without preamble acid soak and alkali neutralization procedure, pickling efficiency is substantially increased, reduces the discharge of acid, the cleaning of steel tube surface greasy dirt
More thoroughly.
Technical scheme is used by the utility model solves its technical problem：
A kind of line Pipe surface derusting device, including support frame, in addition to one end and the anode of pending fastener for connection
Connecting wire, the other end of anode connecting wire are connected with dc source；Online descaling bath is installed, online on support frame as described above
6-10 steel pipe pressure deflector roll is arranged at intervals with descaling bath, steel pipe depresses guide roller surface and depresses deflector roll length direction along steel pipe
Multiple steel pipe guide grooves being adapted to pending steel pipe sizes are interval with, the electricity as negative electrode is installed on online descaling bath inwall
Battery lead plate is solved, electrolysis electrode plate is connected by busbar with dc source.DC electrolysis are to install on online descaling bath inwall
Electrolysis electrode plate is negative electrode, using steel pipe as anode.
Online descaling bath of the present utility model, in acid cleaning process, produced largely in steel tube surface using DC electrolysis
Bubble, coordinate the effect of steel pipe pressure deflector roll, the oxide skin of steel tube surface loosening can be effectively peeled off, without preamble acid soak and alkali
Neutralization procedure, pickling efficiency is substantially increased, reduce the discharge of acid.DC electrolysis are same in the substantial amounts of bubble of steel tube surface generation
When the surfactant in pickle can be caused preferably to play the effect of degreasing so that steel tube surface greasy dirt cleaning it is more thorough
Bottom.
Preferably, the length of the online descaling bath is 6-10m.
Preferably, the steel pipe guide groove has 8-10, steel pipe guide groove body depresses deflector roll around steel pipe.
Preferably, the cell wall of the steel pipe guide groove is provided with multiple circular salient points, the height of salient point in 0.2-0.3mm,
The area of each salient point is 1-2mm2, bump density is 10-15 every square centimeter.It is special by being set on steel pipe guide groove cell wall
Be sized the circular salient point with density, can in steel pipe motion process with steel tube surface friction so that bubble peel off oxide skin
It is easier to come off, strengthens bubble release effect, can more thoroughly derust, and do not damage steel tube surface.
Preferably, it is relatively set with ultrasonic probe on the side of the online descaling bath inwall.The utility model is straight
While stream electrolysis, further coordinate specific ultrasonication, derusting effect can be greatly enhanced.If the frequency of ultrasonic wave
It is higher, derusting effect can be reduced, therefore, the low frequency that the frequency for controlling ultrasonic wave is 20-25KHZ.
The beneficial effects of the utility model are：By to the direct pickling of steel pipe, being neutralized online without preamble acid soak and alkali
Step, pickling efficiency is substantially increased, reduce the discharge of acid, steel tube surface greasy dirt cleans more thoroughly.
