the lifting device (4) is started to drive the drawing device (3) to move upwards, the drawing device (3) is driven to move below the iron removing tank (2) to be cleaned, the drawing straight line driving unit (31) drives the drawing supporting seat (33) to move towards the direction close to the iron removing tank (2), the first drawing block (35) is driven to move below the first positioning groove (2551) in the closing mechanism (25), the lifting device (4) is started to drive the drawing device (3) to move upwards, the drawing supporting plate (34) is abutted to the cover body (23), the first drawing block (35) is enabled to be spliced upwards in the first positioning groove (2551), the limiting linear driving unit (32) drives the closing limiting plate (252) to move downwards and drives the second limiting block (258) to move downwards to a gap between two adjacent first limiting blocks (257), the closing elastic piece (254) is in a compressed state, the drawing straight line driving unit (31) drives the drawing supporting seat (33) to move towards the direction far away from the iron removing tank (2), the first limiting block (25) is driven to move upwards, the first limiting block (23) is enabled to move upwards, the first limiting block (254) is enabled to move upwards in the second limiting block (257) to move downwards towards the first limiting block (25), and the second limiting block (257) to move downwards towards the second limiting block to move upwards towards the first limiting block (25to be in a compression state, and a compression state to move down towards the first limiting block, and a second limiting block (25). The operator collects the magnetic impurities in the tank body (21) to finish the cleaning work of the iron removing tank (2);

After the cleaning work is finished, the drawing and straightening driving unit (31) drives the drawing and straightening supporting seat (33) to move towards the direction close to the iron removing tank (2), so that the cover closing mechanism (25), the cover body (23) and the iron removing rod (22) are driven to move, the second limiting block (258) can move towards the direction close to the iron removing tank (2) along the gap between the two adjacent first limiting blocks (257), after the iron removing rod (22) is completely inserted into the tank body (21), the limiting linear driving unit (32) does not apply pressure on the cover closing limiting plate (252), the cover closing elastic piece (254) is restored to an original state, the cover closing elastic piece (254) drives the cover closing limiting plate (252) to move upwards, the second limiting block (258) is not located in the gap between the two adjacent first limiting blocks (257), the lifting device (4) drives the drawing and straightening driving unit (3) to move downwards, so that the first drawing and straightening driving unit (31) drives the drawing and straightening supporting seat (33) to move towards the direction far away from the iron removing tank (2), and the iron removing rod (22) cannot be completely installed along with the iron removing mechanism (22) and the cover closing elastic piece (23);

the first detection device (6) and the second detection device (7) are used for detecting whether the iron removing rod (22) is in a horizontal state, if the iron removing rod (22) is in the horizontal state in the moving process of the iron removing rod (22), the first detection device (6) and the second detection device (7) can detect the iron removing rod (22), the first detection device (6) and the second detection device (7) transmit corresponding electric signals to the controller, the controller transmits the corresponding electric signals to the drawing and straightening driving unit (31), the drawing and straightening driving unit (31) continues to work, if the iron removing rod (22) is inclined and the inclination angle is larger than a preset value, the first detection device (6) positioned on the upper side can not detect the iron removing rod (22), the second detection device (7) positioned on the lower side can also detect the iron removing rod (22), the first detection device (6) and the second detection device (7) transmit the corresponding electric signals to the controller, and the controller transmits the corresponding electric signals to the drawing and straightening driving unit (31), and the drawing and straightening driving unit (31) stops working.

In addition, the third detection device (8) is used for detecting whether the cover body (23) is completely installed on the tank body (21), if the installation is incomplete, the third detection device (8) can detect that the second limiting block (258) protrudes out of the cover closing installation plate (251) in the vertical direction, the third detection device (8) transmits corresponding electric signals to the controller, the controller transmits corresponding electric signals to the drawing straight line driving unit (31), the drawing straight line driving unit (31) pauses to work, the drawing straight line driving unit (31) continues to work after the incomplete installation is caused by processing, if the installation is complete, the third detection device (8) can not detect that the second limiting block (258) protrudes out of the cover closing installation plate (251) in the vertical direction, the third detection device (8) transmits corresponding electric signals to the controller, the controller transmits corresponding electric signals to the drawing straight line driving unit (31), and the drawing straight line driving unit (31) continues to work until the drawing straight line driving unit (31) drives the drawing support seat (33) to move to a preset position.
