Abstract

The invention belongs to the field of manufacturing technology, and specifically discloses a device and method for continuous pickling of titanium and titanium alloy oil pipes, which have low safety risks and are beneficial to control the surface quality and size uniformity of oil pipe pickling. The equipment for continuous pickling of titanium and titanium alloy oil pipes includes an equipment box, an actuator, a circulation mechanism and an acid mist collection device. The equipment for continuous pickling of titanium and titanium alloy tubing can fix the tubing on the rotary shaft and drive it to rotate in the equipment box to complete the pickling, neutralization and cleaning steps, which is beneficial to ensure the surface quality and size of the tubing pickling Uniformity; at the same time, the acid liquid, neutralizing liquid and cleaning liquid are pumped separately, which can not only improve the pickling efficiency, but also reduce the labor intensity of workers and reduce the risk of corrosion damage; in addition, during the pickling process, the acid produced The mist can be pumped into the lye tank by the fan through the acid mist discharge hole for neutralization treatment, which avoids the risk of acid mist overflow and meets the environmental protection requirements.

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...
