Abstract
The utility model discloses pickling processes device before a kind of steel pipe epoxy powder spray.The device includes steel pipe conveyer, pickling storehouse, high pressure washing storehouse and air drying cabin.Steel pipe is first passed through pickling storehouse and carries out acid solution spray, then to the progress pure water cleaning of high pressure washing storehouse, finally reached air drying cabin and air-dried, remove the moisture of remained on surface, to ensure that steel tube surface pickling is clean and does not return rust by transmission device.The beneficial effects of the utility model：Pickling processes device can control pickling, cleaning and air drying process respectively before steel pipe epoxy powder spray, individually operated to be independent of each other, and avoid steel tube surface from occurring returning rust phenomenon, ensure pickling quality.
Description
Technical field
Pipeline spraying field is the utility model is related to, is filled more particularly, to pickling processes before a kind of steel pipe epoxy powder spray
Put.
Background technology
Applied outside pipeline in industry, the FBE of the bottom serves heavy to closing in whole protective system
The effect wanted.FBE resistance to corrosion is evaluated, most important of which index is exactly cathodic disbonding；As pipeline uses
Environment is more and more severe, the requirement also more and more higher peeled off to coated cathode.In long-term production application, steel tube surface spraying
Preceding handling process is relatively simple, and typically steel pipe is placed on inside a storehouse and carries out pre-treatment operation, pre-treatment includes in storehouse
Acid solution spray and pure water clean two parts, no air knife drying.Acid solution is sprayed and pure water cleaning is placed in same storehouse, during work
It cannot be guaranteed that influencing each other, pickling quality and cleaning quality is caused not to reach standard requirement；Meanwhile the steel pipe after cleaning such as can not
Air-dry in time, surface easily occurs returning rust, influences final coating antikathode peeling effect.
Utility model content
The purpose of this utility model be to overcome the steel pipe after above-mentioned prior art steel pipe pre-treatment storehouse spray acid easily return rust,
Influence final coating antikathode peeling effect shortcoming.Pickling processes device before a kind of steel pipe epoxy powder spray is provided, including
Steel pipe conveyer, pickling storehouse, high pressure washing storehouse and air drying cabin, it is provided with the pickling storehouse to adjust according to steel pipe market speed and sprays
The low pressure acid solution shower of pressure is drenched, pickling storehouse is arranged on and exports for rinsing the residual sour high pressure washing storehouse of steel tube surface, it is described
High Pressure Pure Water flush pipe is provided with high pressure washing storehouse, high pressure washing storehouse is arranged on and exports for drying air-drying for steel tube surface moisture
Storehouse, interior be provided with of the warehouse for drying air-dry air knife component.
Further, described low pressure acid solution shower one end is connected with acid solution bucket, and the other end is connected with sprinkler head.
The pre-treating method of pickling processes device, comprises the following steps before steel pipe epoxy powder spray,
Steel pipe is sent to pickling storehouse and carries out sufficient acid solution by low pressure acid solution shower by the first step, steel pipe conveyer
Spray；
Second step, steel pipe after above-mentioned acid solution has sprayed are sent to high pressure washing storehouse using pure by steel pipe conveyer again
Water fully cleans；
3rd step, the steel pipe cleaned up in high-pressure chamber is sent in air drying cabin by air-drying air knife by steel pipe conveyer
Component is dried, i.e. pre-treatment is completed.
After said structure, the utility model is compared to the prior art advantageously：Can control respectively pickling,
Cleaning and air drying process, it is individually operated to be independent of each other, avoid steel tube surface from occurring returning rust phenomenon, ensure that pickling quality.
Brief description of the drawings
Fig. 1 is pickling processes apparatus structure schematic diagram before steel pipe epoxy powder spray of the present utility model.
In figure：1-pickling storehouse, 2-high pressure washing storehouse, 3-air drying cabin, 4-low pressure acid solution shower, 5-High Pressure Pure Water
Flush pipe, 6-air-dry air knife component, 7-steel pipe.
Embodiment
The purpose of this utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, embodiment is not
It can repeat one by one herein, but therefore embodiment of the present utility model is not defined in following examples.
As shown in figure 1, pickling processes device before a kind of steel pipe epoxy powder spray, including steel pipe conveyer, pickling storehouse
1st, high pressure washing storehouse 2 and air drying cabin 3, the low pressure acid according to the transporting velocity of steel pipe 7 regulation spray pressure is provided with the pickling storehouse 1
Liquid shower 4, it is arranged on pickling storehouse 1 and exports for rinsing the residual sour high pressure washing storehouse 2 in the surface of steel pipe 7, the high pressure washing storehouse 2
It is interior to be provided with High Pressure Pure Water flush pipe 5, it is arranged on high pressure washing storehouse 2 and exports air drying cabin 3 for drying the surface moisture of steel pipe 7, institute
State to be provided with air drying cabin 3 and air-dry air knife component 6, steel pipe 7 is delivered to pickling storehouse 1 by the conveyer of steel pipe 7 successively, high pressure is rushed
Bring down stocks 2 and air drying cabin 3.The one end of low pressure acid solution shower 4 is connected with acid solution bucket, and the other end is connected with sprinkler head, the spray of low pressure acid solution
Air-dry time in the position of shower pipe 4, pickling time, high pressure washing storehouse scavenging period and air drying cabin can be according to the transfer rate of steel pipe 7
It is adjusted.The pickling storehouse 1, high pressure washing storehouse 2 and air drying cabin 3 are disposed side by side in cavity and separated with environment, the steel pipe
Conveyer is arranged on the bottom of steel pipe 7, and power is provided for the transmission of steel pipe 7.
Embodiment 1
Pickling processes specific implementation step before a kind of steel pipe epoxy powder spray：
First, steel pipe 7 is sent to pickling storehouse 1 and carried out by the shower nozzle of low pressure acid solution shower 4 spray acid by steel pipe conveyer
Sufficient acid solution spray；
Secondly, steel pipe 7 is sent to high pressure washing storehouse 2 with pure by steel pipe conveyer again after above-mentioned acid solution has sprayed
Water fully cleans, and removes the acid solution of the surface residual of steel pipe 7；
Finally, the steel pipe 7 cleaned up in high pressure washing storehouse 2 is sent in air drying cabin 3 by wind by steel pipe conveyer
Dry-air blast knife assembly 6 is dried, i.e., pretreatment process is completed.
By the steel pipe 7 after derusting by steel pipe transmission device, first pass through pickling storehouse 1 and carry out acid solution spray, then rushed to high pressure
Bring down stocks 2 carry out pure water cleanings, finally reach air drying cabin 3 and air-dried, remove remained on surface acid solution and the surface of steel pipe 7 is without water
Point, reach the effect that the surface acid-washing of steel pipe 7 does not return rust totally.
The present apparatus can control pickling, cleaning and air drying process respectively, individually operated and do not influence between each other, avoid steel pipe
Surface occurs returning rust phenomenon, ensures pickling quality.
