step two: the rotary lifting assembly drives the feeding pipe (11) to rotate, the feeding pipe (11) drives the rotary table (5) to rotate relative to the supporting ring (6) through the plug-in synchronous unit, the rotary plug-in rotary filtering assembly filters the N-methylpyrrolidone, and the filtered N-methylpyrrolidone is discharged through the discharge port (3);
step three: when the use time is prolonged and the filtered impurities are blocked at the lower half part of the plug-in type rotary filter assembly, the rotary lifting assembly drives the feeding pipe (11) to move upwards so as to separate the sealing shell (12) from the feeding pipe (10), and the feeding pipe (11) and the sealing shell (12) are prevented from interfering with the turnplate (5) and the feeding pipe (10) to turn over;
Step four: when the sealing shell (12) is separated from the material pipe (10), a worker drives the rotary seat (4) to turn over one hundred and eighty degrees through the turning unit, so that the blocked lower half part of the plug-in type rotary filter assembly is turned over to the upper part, the upper half part of the original plug-in type rotary filter assembly is turned over to the lower part, the material pipe (11) is driven to move downwards through the rotary lifting assembly, and the top end of one of the material pipes (10) positioned above is inserted into the sealing shell (12);
step five: n-methyl pyrrolidone enters the plug-in type rotary filter assembly through the feed pipe (11) and one of the feed pipes (10) positioned above, the feed pipe (11) and the plug-in type rotary filter assembly are driven to rotate through the rotary lifting assembly, the N-methyl pyrrolidone is filtered through the rotary plug-in type rotary filter assembly, and the filtered N-methyl pyrrolidone is discharged through the discharge port (3).
