[0026] How it works

[0027] It should be noted that the utility model is a fine filtering device for pharmaceutical equipment. When in use, the turntable 3 is first rotated, and the rotation of the turntable 3 drives the movable rod 2 to rotate on the filtering device body 1. The rotation of the movable rod 2 drives the rotating shaft 4 to drive the semi-ball valve 5 to rotate in the spherical groove in the filtering device body 1. The turntable 3, the movable rod 2, the rotating shaft 4 and the semi-ball valve 5 rotate at the same time, so that the semi-ball valve 5 is rotated under the indication of the arrow on the turntable 3 until the arrow on the turntable 3 is parallel to the direction in which the first elbow 6 is connected to the filter tank 7, and the protruding semi-ball of the semi-ball valve 5 does not block any through hole of the filtering device body 1. The staff connects the output pipe of the liquid to be filtered with the open flange on the filtering device body 1. The medicine to be filtered is connected to the filter device body 1, and then enters the same first curved pipe 6 connected at both ends of the filter device body 1. The medicine to be filtered enters the two same filter tanks 7 through the two same first curved pipes 6. After entering the filter tank 7, the medicine to be filtered is blocked by the first baffle 8. Under the restriction of the first baffle 8, the medicine to be filtered passes through the gap between the first baffle 8 and the bottom of the inner wall of the filter tank 7. Then, the medicine to be filtered impacts the first fixed block 9. Under the blocking and guidance of the first fixed block 9, the medicine to be filtered passes through the gap between the first fixed block 9 and the top of the inner wall of the filter tank 7. After passing through the first fixed block 9, the medicine to be filtered passes through the first filter screen 10 for the first filtration. After the liquid medicine is filtered for the first time by the first filter screen 10, it is blocked by the second baffle 11. Under the restriction of the second baffle 11, it passes through the gap between the second baffle 11 and the bottom of the inner wall of the filter tank 7. Then, the liquid medicine to be filtered impacts the second fixed block 12. Under the blocking and guidance of the second fixed block 12, it passes through the gap between the second fixed block 12 and the top of the inner wall of the filter tank 7. After passing through the second fixed block 12, the liquid medicine to be filtered passes through the second filter screen 13 for a second filtration. After the liquid medicine to be filtered passes through the second filter screen 13 for a second filtration, it is blocked by the third baffle 14. Under the restriction of the third baffle 14, it passes through the gap between the third baffle 14 and the bottom of the inner wall of the filter tank 7. After passing through, the medicine to be filtered impacts the third fixed block 15, and passes through the gap between the third fixed block 15 and the top of the inner wall of the filter tank 7 under the obstruction and guidance of the third fixed block 15. After passing through the third fixed block 15, the medicine to be filtered passes through the third filter screen 16 for the third filtration. After the medicine to be filtered passes through the third filter screen 16 for the third filtration, the medicine after three filtrations passes through the filter tank 7 into the second curved pipe 17. The medicine after three filtrations impacts the cover plate 21, and the cover plate 21 is connected to the metal spring 20 on the fixing ring 19 to open. The medicine after three filtrations passes through the second curved pipe 17 and then enters the three-way pipe 18 for discharge, thereby achieving the purpose of multiple guiding of the medicine residue in the filtered medicine.

[0028] After the two identical filter tanks 7 have been used for a period of time, the hemispherical valve 5 is rotated according to the indication of the arrow on the turntable 3 until the arrow on the turntable 3 is perpendicular to the direction of one of the first elbows 6 connected to the filter device body 1, and the other first elbow 6 continues to work normally. After the hemispherical valve 5 blocks the output of one of the first elbows 6, the liquid to be filtered no longer enters the blocked first elbow 6. When the normally filtered liquid reaches the three-way pipe 18 and wants to reversely pass through the second elbow 17 on one side of the filter tank 7 that has been closed and no liquid enters, the liquid impacting in the reverse direction impacts the cover plate 21 in the second elbow 17. The cover plate 21 is limited and blocked by the fixing ring 19, and the liquid cannot be reversed and retained in the filter tank 17. Then the through pipe connected to the blocked first elbow 6 is disassembled. Filter tank 7, pour the liquid medicine in the filter tank 7 into the bucket for collection, and then flush the filter tank 7 with clean water through the connection port between the filter tank 7 and the second elbow 17 to rinse the filter tank 7, and the clean water passes through the third filter screen 16, the third fixed block 15, the third baffle 14, the second filter screen 13, the second fixed block 12, the second baffle 11, the first filter screen 10, the first fixed block 9 and the first baffle 8 in turn for flushing, until the clean water is discharged through the other port of the filter tank 7, and the blocked drug residues on the third filter screen 16, the second filter screen 13 and the first filter screen 10 are reversely flushed and dropped, and after cleaning the filter tank 7, the filter tank 7 is installed back in place, and the above operation is repeated, and another identical filter tank 7 is disassembled and cleaned to achieve the purpose of uninterrupted operation and cleaning of the blocked drug residues.
