Abstract

The invention belongs to the manufacturing technical field and specifically discloses a plant and method used for continuous acid washing of a titanium and titanium alloy oil pipe, and the plant and method are low in safety risk and beneficial to control over the oil pipe acid washing surface quality and size uniformity. The plant used for continuous acid washing of the titanium and titanium alloyoil pipe comprises a plant box, an executive mechanism, a circulating mechanism and an acid mist collecting device. By the adoption of the plant used for continuous acid washing of the titanium and titanium alloy oil pipe, the oil pipe can be fixed to a rotation pipe shaft so as to be driven by a drive device to rotationally finish an acid washing step, a neutralizing step and a washing step in the plant box, and the oil pipe acid washing surface quality and size uniformity can be guaranteed; meanwhile, acid liquid, neutralizing liquid and washing liquid are pumped through pumps, acid washingefficiency can be improved, the labor intensity of workers is reduced, and corrosion harm risks are reduced; and in addition, in the acid washing process, generated acid mist can be exhausted by a draught fan through an acid mist exhausting hole into an alkali liquor barrel to be neutralized, the risk that the acid mist overflows is avoided, and the requirement for environment friendliness is met.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to equipment and method for continuous pickling of titanium and titanium alloy oil pipes. Background technique [0002] Pickling is an intermediate process in the processing of titanium and titanium alloy oil pipes. The existing pickling process is carried out by vertical or open methods. The vertical method is to fix the oil pipe vertically in the pickling tank, and use a pump to pump the pickling solution from the upper part of the oil pipe for pickling; the surface quality and size of the head and bottom of the oil pipe after pickling by this method are not uniform, and It is more difficult to control the pickling surface quality and size uniformity of longer tubing. The open method is to use the crane to lift the hanging basket with the workpiece and immerse it in the acid tank for pickling. The surface quality and size uniformity of the oil pipe after pickli...
