After the pickling finishes, hoist motor 60 drive axis of rotation 61 rotates, wire rope 62 is around last axis of rotation 61, thereby hold frame 5 and steel pipe and shift out pickling bath 10, utilize the difference in height of arc frame 56, make things convenient for the steel pipe to discharge the pickle rapidly, it remains on the steel pipe inside wall to reduce the pickle, start air exhauster 74, accelerate to hold frame 5 in the air flow, thereby the harmful gas who produces on the drive steel pipe lateral wall flows, thereby can reduce the harmful gas and give off in the workshop, reduce the possibility that the workman adsorbs harmful gas, thereby can protect the workman healthy.
When the accommodating frame 5 rotates, the air hood 76 rotates along with the accommodating frame 5 through the hose 78, and the air blowing drying of the inner cavity of the steel pipe can be continuously performed through the air hood 76.
After the drying, power motor 40 drives support frame 3 again and moves to the top of bonderizing pond 14, and hoist motor 60 drive holding tank and steel pipe carry out the bonderizing reaction in getting into bonderizing pond 14, and the back that the reaction finishes, hoist motor 60 drives holding tank and steel pipe again and shifts out bonderizing pond 14, and through the difference in height of arc frame 56, the phosphating solution in the steel pipe can discharge rapidly, is favorable to reducing the phosphating solution that remains on the steel pipe inside wall.
The exhaust fan 74 is started when the containing frame 5 moves out of the phosphating tank 14, so that the air flow in the containing frame 5 is accelerated, the flow of harmful gas emitted from the outer side wall of the steel pipe is driven, the harmful gas emission into a workshop can be reduced, the possibility of adsorbing the harmful gas by workers can be reduced, and the health of the workers can be protected.
The power motor 40 drives the supporting frame 3 to move to the upper part of the clean water tank 13 again, the winding motor 60 drives the accommodating frame 5 to enter the clean water tank 13 for cleaning, and the exhaust fan 74 is stopped, after cleaning, the hoist drives the containing frame 5 and the steel pipe to move out of the clean water tank 13, the blower 72 blows air to dry the steel pipe again, and at the same time, the air is blown to the inner cavity of the steel pipe from the air cover 76, thereby accelerating the residual water in the inner cavity of the steel pipe to flow out of the steel pipe, driving the containing frame 5 to move above the draining groove 12 by the winding motor 60, driving the containing frame 5 to rotate by the rotating motor 50, driving the driving lever 57 to rotate by the driving lever 57 motor 57, thereby can drive the steel pipe and rotate, power motor 40 drive holds frame 5 and steel pipe and removes to the top of draining groove 12 and dripdrying, and air-blower 72 carries out the blow drying to the steel pipe surface to this can be dried the steel pipe.
The draining tank 12 is arranged between the cleaning tank 11 and the clean water tank 13, so that the structure of the device can be simplified, the size of the device can be reduced, and the occupied area of the device can be reduced.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
