Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe production equipment, and more specifically to an environmentally friendly seamless steel pipe production equipment. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe.

[0003] At present, in the production process of seamless steel pipes, production equipment is needed to pickle the surface of seamless steel pipes. However, it is not easy for the pickling equipment to thoroughly clean the surface debris of the seamless steel pipes during the pickling process, which reduces the cleaning effect of the debris. Moreover, the cleaned debris can easily cause the mesh of the filter to be blocked, requiring manual cleaning, which brings inconvenience.

[0004] For example, announcement number CN213977899U discloses a cold-drawn seamless steel pipe production equipment, which includes a pickling box with a partition plate fixedly connected to the inside of the pickling box, a cleaning chamber is provided inside the pickling box and on the left side of the partition plate, and two receiving plates are fixedly connected to the inside of the cleaning chamber.

[0005] It can be seen from the above-mentioned public scheme that during the pickling process, the seamless steel pipe is sprayed by a nozzle, and the debris on the bottom surface may not be cleaned, which reduces the debris cleaning effect, and the set filter plate is prone to cause debris accumulation, thereby clogging the seepage holes.
