FIG. 3 is a side view of the cleaning tank.
In the figure: 1. the cleaning device comprises a cleaning pool, 2, a galvanizing pool, 3, a first driving device, 4, a manipulator, 5, a beam, 6, a conveying line, 7, a fixing rod, 8, a fan, 9, a spray header, 10, a water storage tank, 11, a cold water tank, 12, a first gear, 13, a second gear, 14, a second driving device, 15, a bevel edge, 16, an air suction cover, 161, a cover body, 17, an exhaust fan, 18, a base, 19, a pipeline, 20 and a steel pipe.
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in the drawing, the utility model discloses a device for steel pipe galvanizing, the device is including wasing pond 1 and galvanizing zinc bath 2, 2 tops in galvanizing zinc bath are provided with drag for a tub device, drag for a tub device and include first drive arrangement 3 and 3 driven manipulators 4 of first drive arrangement, first drive arrangement 3 install on a crossbeam 5 and can remove on the crossbeam 5, one side of crossbeam 5 is provided with transfer chain 6, 6 tops of transfer chain are provided with dead lever 7, be provided with a plurality of fans 8 on the dead lever 7, still be provided with shower head 9 on the dead lever 7, the below of transfer chain 6 is provided with storage water tank 10, shower head 9 is connected with cold water storage cistern 11.
Furthermore, a base 18 is arranged on the conveying line 6, a first gear 12 and a second gear 13 which are matched with each other are arranged on the base 18, the first gear 12 and the second gear 13 are driven to rotate by two second driving devices 14 respectively, the rotating directions of the first gear 12 and the second gear 13 are opposite, and at least two first gears 12 and at least two second gears 13 are arranged. The steel pipe 20 is placed between the first gear 12 and the second gear 13, and the first gear 12 and the second gear 13 rotate in opposite directions to drive the steel pipe 20 to rotate, so that air cooling and water cooling can be fully and uniformly received.
Furthermore, the surfaces of the first gear 12 and the second gear 13 are provided with elastic layers (not shown), and the elastic layers on the surfaces of the first gear 12 and the second gear 13 reduce damage to the surface of the steel pipe 20.
Further, the transfer wire 6 is provided with bevel edges 15 on both sides. The sloping edge 15 can help to quickly flow the sprayed water into the water storage tank 10.
Furthermore, two air suction hoods 16 are arranged at the top of the cleaning pool 1, and the space between the two air suction hoods 16 can accommodate the manipulator 4. Because the cleaning generally adopts the pickling, can suck away the hydrochloric acid that volatilizes through the cover 16 that induced drafts, can not distribute in the atmosphere, influence staff's health.
Furthermore, the air suction hood 16 comprises a hood body 161 and an exhaust fan 17 connected with the hood body 161, wherein the exhaust fan 17 is connected with the water storage tank 10 through a pipeline 19, and the adsorbed volatile hydrochloric acid is introduced into the water storage tank 10 for absorption, so that water cooling water is fully utilized.
The device of this application is when using, and steel pipe 20 enters earlier and washs the pond and washs, and accessible manipulator 4 snatchs and gets into galvanizing bath 2, accomplishes the zinc-plating back, and manipulator 4 presss from both sides steel pipe 20, and first drive arrangement 3 removes and drives manipulator 3 and remove, and manipulator 4 places steel pipe 20 on transfer chain 6, and transfer chain 6 drives steel pipe 20 and passes through the forced air cooling earlier, then through the water-cooling, accomplishes whole cooling process.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
