When the device of the embodiment is used, the state of the auxiliary assembly 4 shown in fig. 6 is set to be an initial state, at the moment, the blades 407 are in a vertical state, the outer cambered surfaces of the blades 407 are attached to the inner wall of the bottom of the rectifying tower 1, the springs 408 are in a semi-compressed state, the electromagnets 409 are positioned at the lower ends of the blades 407, the electromagnets 409 are started at the same time when the rectifying process begins, the electric push rod 401 is started to extend upwards, then the mounting seat 402 is driven to move upwards, the sliding cylinder 403 and the blades 407 are driven to move upwards, the electromagnets 409 move upwards, the distance between the electromagnets 409 and the permanent magnet ring 410 is gradually shortened, the electromagnets 409 are electrified to generate magnetism, the magnetic poles on the opposite sides between the electromagnets 409 and the permanent magnet ring 410 are the same, and then the blades 407 on the two sides are pushed to be close to the mounting seat 402 by utilizing magnetic repulsion force when the blades 407 move upwards, the guide rod 404 slides along the sliding cylinder 403 to the mounting seat 402, meanwhile, the guide rod 404 slides and realizes the rotation of the guide rod 404 by utilizing the cooperation of the bulge 406 and the spiral groove 405, so that the blade 407 is inclined, the blade 407 is in the state shown in fig. 7, at the moment, the electromagnet 409 is positioned at the bottom end of the blade 407, the electromagnet 409 still corresponds to the permanent magnet ring 410, the blade 407 is still positioned in the bottom liquid, a gap exists between the blade 407 and the bottom inner wall of the rectifying tower 1, the motor 202 is restarted to drive the main gear 203 to rotate, then the auxiliary gear 201 drives the rotating tube 111 to rotate clockwise, and then drives the inclined blade 407 to rotate, so that the fluctuation of the bottom liquid of the rectifying tower 1 is realized, and at the same time, an upward pushing force can be applied to the bottom liquid by utilizing the inclination direction of the blade 407 and the clockwise rotation of the rotating tube 111, therefore, heavy component impurities in the tower bottom liquid are always in a suspension state by utilizing fluctuation of the tower bottom liquid while the tower bottom liquid is discharged into the reboiler 113, impurities are prevented from being precipitated on the inner wall of the bottom of the rectifying tower 1 to be condensed into dirt, meanwhile, the impurities are prevented from being attached to the filter screen 304 to cause the blockage of the filter screen 304, and ferromagnetic impurities can be also in a suspension state, so that the permanent magnet ring 410 can absorb and remove the ferromagnetic impurities in the tower bottom liquid better.
In addition, under the action of the upper liquid pump 112, part of impurities at the bottom of the bottom liquid flows downwards along with the bottom liquid and then is attached to the filter screen 304, so that the filter screen 304 is blocked, when the liquid flow sensor 118 detects that the liquid flow entering the discharge pipe 108 is smaller than the set threshold value of the liquid flow sensor 118, the filter screen 304 is actively judged to be blocked, at the moment, the electromagnet 409 is closed, the magnetic repulsive force between the permanent magnet ring 410 and the electromagnet 409 disappears, the spring 408 drives the blade 407 to reset, the blade 407 is restored to a vertical state and is attached to the inner wall of the rectifying tower 1, the electric push rod 401 is started to shrink, and then the blade 407 is driven to move downwards, in the process, the blade 407 reaches the initial state as shown in fig. 6 firstly, the blade 407 continues to move downwards along with the continued shrinkage of the electric push rod 401, and because the bottom of the rectifying tower 1 is of a hemispherical structure, the radius of the cross section is gradually reduced, the blades 407 on two sides are horizontally extruded to the mounting seat 402 by the inner wall of the bottom of the rectifying tower 1 to be close, the guide rod 404 also slides to the mounting seat 402, the guide rod 404 rotates by the cooperation of the bulge 406 and the spiral groove 405, the blades 407 also rotate along with the rotation, the blades 407 rotate on the basis of the initial state shown in fig. 6, the blades 407 are in the states shown in fig. 8 and 9, at the moment, the electromagnet 409 is positioned at one lower end of the blades 407, the electromagnet 409 corresponds to the bottom of the filter screen 304, at the moment, the motor 202 is started to drive the rotating tube 111 to rotate through the main gear 203 and the auxiliary gear 201, the motor 202 is driven to drive the rotating tube 111 to rotate anticlockwise, in the process of the rotation of the blades 407, the tower bottom liquid is pressed downwards, and the pressure of the tower bottom liquid on the filter screen 304 is increased, therefore, impurities blocked in the filter screen 304 can be pressed out by using larger hydraulic pressure, so that the filter screen 304 is cleared.
However, when the liquid flow sensor 118 detects that the liquid flow entering the discharge pipe 108 is still smaller than the set threshold value of the liquid flow sensor 118, it indicates that the filter screen 304 is not thoroughly blocked, at this time, the rotation direction of the motor 202 is changed, so that the rotary pipe 111 rotates clockwise, and simultaneously, the electromagnet 409 is started, the bottom of the filter screen 304 can be adsorbed by using the magnetic attraction of the electromagnet 409, so that the bottom of the filter screen 304 is opened to the outside, and when the liquid flow sensor 118 is opened, part of tower bottom liquid is discharged into the rotary pipe 111 from the opening and closing position of the bottom of the filter screen 304, so that the opening and closing angle is smaller than 45 degrees, excessive tower bottom liquid and heavy component impurities are prevented from being discharged into the rotary pipe 111, meanwhile, as the blade 407 drives the electromagnet 409 to rotate, the magnetic attraction of the electromagnet 409 to the bottom of the filter screen 304 is eliminated after one of the electromagnets 409 completely passes through one of the filter screens 304, the hydraulic action of the bottom liquid is reset under the hydraulic action of the bottom of the electromagnet 409, thereby realizing intermittent swing of the bottom of each filter screen 304, further blocking of the filter screen 304 is realized, and sufficient bottom liquid still enters the reboiler 113, and sufficient bottom liquid is guaranteed to enter the rectifying tower 1, and when the blade 407 is used, and when the blade 407 is rotated, the blade is used to generate the blade to cause the heavy component to be in a state, and the suspended component to be still in a state, as shown in the rectifying tower, and the state, and the suspended component is still in the state, and after the tower is recovered to be in the state, and after the tower is in the state, and has been recovered.
