Description

Technical Field

[0001] This utility model relates to the field of rust removal technology, and in particular to a rapid rust removal device for pressure vessels. Background Technology

[0002] In existing technology, a pressure vessel refers to a closed device that holds gas or liquid and withstands a certain pressure. Commonly used pressure vessels include natural gas tanks and pressure vessels. Rust removal from pressure vessels is generally divided into mechanical rust removal methods (sandblasting, shot blasting, etc.), chemical rust removal methods (pickling), and electrochemical rust removal methods (anodic and cathodic rust removal). Vibration rust removal is also a type of mechanical rust removal method.

[0003] A search revealed Chinese patent application number 202421102341.5, which discloses a rapid rust removal device for pressure vessels. The device includes a rust removal box. A positioning mechanism for locating the pressure vessel is located at the bottom right side of the rust removal box. Electric telescopic columns are fixed to the left and right ends of the inner top wall of the rust removal box. A fixing plate is fixed to the lower surface of the electric telescopic columns. A rust removal plate is located on the lower side of the fixing plate. Removal mechanisms for disassembling the rust removal plate are located at both ends of the front of the fixing plate. The positioning mechanism includes a motor fixed to the bottom right side of the rust removal box. Rotary shafts are rotatably connected to the bottom of opposite sides of the left and right side walls of the rust removal box via bearings. The output shaft of the motor passes through the right side wall of the rust removal box and extends into the inner cavity of the rust removal box, where it is fixed to the right-end rotating shaft. Rotating plates are fixed to the opposite sides of the two rotating shafts.

[0004] The above-mentioned patent has the following shortcomings: the device removes rust from the outer wall of the pressure vessel by means of a rust removal plate, which makes it easy for rust spots to remain on the outer wall of the pressure vessel. Moreover, it is not convenient to perform comprehensive rust removal on the surface of the pressure vessel. During the rust removal process, the wall thickness of the pressure vessel is easily uneven, which reduces the rust removal effect. Utility Model Content
