Embodiment
[0037] refer to Figure 1-5 , is a seamless steel pipe pickling device disclosed in the present invention, including a pickling tank 1 . The pickling tank 1 is a cubic groove, and the top opening of the pickling tank 1 is provided with a cover 2 . The bottom end of a vertical side wall of the pickling tank 1 is provided with a drain pipe 3, which communicates with the inner cavity of the pickling tank 1, and the drain pipe 3 is provided with a valve (not shown in the figure).
[0038] The pickling tank 1 is rotatably connected with a rotating shaft 4, and the pickling tank 1 is provided with a motor 5 connected with the rotating shaft 4 for driving the forward rotation and reverse rotation of the rotating shaft 4, and a vertical outer wall of the pickling tank 1 is provided with The supporting plate 14 on which the motor 5 is placed. The rotating shaft 4 is provided with several evenly distributed connecting rods 6 around its central axis, and the end of the connecting rods ...

The invention relates to a seamless steel tube pickling device and a pickling method. The seamless steel tube pickling device comprises a pickling tank, a cover body is arranged at an opening of the pickling tank, a drain pipe is arranged on the pickling tank, a rotating shaft is arranged in the pickling tank, and a motor connected with the rotating shaft and used for driving the rotating shaft to rotate forwards and backwards is arranged outside the pickling tank. A plurality of uniformly-distributed connecting rods are arranged at the rotating shaft around the center axis of the rotating shaft, an acid pickling shell is arranged at the end, away from the rotating shaft, of each connecting rod, the acid pickling shells are used for containing a single seamless steel tube, the length of an inner cavity of each acid pickling shell is larger than that of the single seamless steel tube, and the diameter of the inner cavity of each acid pickling shell is larger than that of the single seamless steel tube. The acid pickling shells comprise first half shells and second half shells, connecting assemblies are arranged between the first half shells and the second half shells, and the connecting assemblies are used for achieving detachable connection of the first half shells and the second half shells. All parts of the seamless steel tube can be fully pickled, so that the acid pickling uniformity and the acid pickling quality of the seamless steel tube are improved.
Description
technical field [0001] The invention relates to the technical field of pickling equipment, in particular to a pickling device and a pickling method for seamless steel pipes. Background technique [0002] Seamless steel pipe refers to steel pipes without connecting gaps, which are usually used as pipes for transporting fluids, such as oil, natural gas, gas, etc. According to the production method, seamless steel pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacking pipes. According to the cross-sectional shape, seamless steel tubes are divided into two types: round tubes and special-shaped tubes. The special-shaped tubes have square, oval, triangular, hexagonal, melon-shaped, star-shaped, finned tubes and other complex shapes. [0003] The seamless steel pipe needs to go through the pickling step in the production and processing. In the prior art, when the seamless steel pipe is pickled, the bundled seamless steel pipe is p...
