After the impregnation, the moving frame 321 is reset, and the moving frame 321 can be rotated by the motor 323 at this time. Therefore, by rotating the flange, it is very convenient to quickly recover the passivation liquid on the surface of the flange by using centrifugal force. The bottom of the moving frame 321 is set to be hollow, and a moving block 327 is set at the bottom of the moving frame 321. A reciprocating screw 328 is fixedly installed at the bottom of the moving frame 321. The reciprocating screw 328 penetrates the moving block 327 and is slidably connected to the moving block 327.

After the impregnation, the moving frame 321 is reset. At this time, the moving frame 321 can be rotated by the motor 323, so that the flange is rotated, and the passivation liquid on the surface of the flange is quickly recovered by the centrifugal force, which is very convenient. When the moving frame 321 rotates, the corresponding reciprocating screw 328 is synchronously driven to rotate, so that the reciprocating screw 328 and the outer moving block 327 can perform threaded motion, driving the moving block 327 to move up and down reciprocatingly and continuously at the bottom of the moving frame 321 The parts are impacted and vibrated, thereby further improving the efficiency of recovering the passivation liquid. When rotating, the electric push rod 342 can be moved downward to move the multiple placement screens 31 downward, and the multiple flanges can be fixed by clamping, so that the flanges remain stable when being rotated to recover the passivation liquid.
