In order to solve this technical problem, this example discloses the following technical content;

[0027] A small extraction and filtration device for pharmaceutical preparations includes a filter tank 1 and a tank cover 9 installed at its top. A filter assembly is arranged below the tank cover 9. A discharge pipe 2 is installed at the bottom of the filter tank 1, and a control valve 3 is installed inside the discharge pipe 2. An extrusion assembly is installed at the top of the filter tank 1, as shown in Figures 2 and 3. The extrusion assembly includes a first motor 4, a reverse screw 5, a first moving plate 6, a limiting rod 7, and a second moving plate 8. The first motor 4 is fixed on the left side of the filter tank 1. The output end of the first motor 4 is fixed with the reverse screw 5. The outer end of the reverse screw 5 is threadedly connected to the first moving plate 6. The first moving plate 6 and the second moving plate 8 are symmetrically arranged about the center line of the feed pipe 10. Two sets of filter bags 16 and feed pipes 10 are provided. A limiting rod 7 is fixed at the rear end of the filter tank 1. A second moving plate 8 is arranged on the outer side of the limiting rod 7. The reverse screw 5 is rotatably mounted on the filter tank 1.

[0028] The liquid mixture of medicine flows from the feed pipe 10 to the filter bag 16 inside the filter assembly. After being filtered by the filter bag 16, the liquid flows to the bottom of the filter tank 1. The side plate 15 has filter holes inside, and the medicine can flow out from the filter holes of the side plate 15. The second motor 11 inside the stirring assembly is started. The second motor 11 drives the central rod 12, stirring blade 13 and scraper 14 to rotate. The rotation of the central rod 12, stirring blade 13 and scraper 14 stirs the medicine, making the medicine evenly mixed. The rotation of the scraper 14 cleans the inner wall of the filter tank 1.

[0029] Stop feeding liquid medicine into feed pipe 10, start first motor 4, first motor 4 drives reverse screw 5 to rotate, first moving plate 6 threaded to reverse screw 5 moves relative to each other, so side plate 15, first moving plate 6 and second moving plate 8 move inward, side plate 15 squeezes filter bag 16, separates liquid medicine from the dregs inside filter bag 16, and the movement trajectory of second moving plate 8 is limited by limiting rod 7;

[0030] When it is necessary to remove the dregs, lift the lid 9 upwards so that the lid 9 leaves the filter tank 1. The limiting rod 7 and the reverse screw 5 will not obstruct the rising of the stirring blade 13 and the scraper 14. Then lift the side plate 15 upwards so that the side plate 15 leaves the first moving plate 6 and the second moving plate 8. The filter bag 16 can then be removed and the dregs inside the filter bag 16 can be poured out.

[0031] Open the control valve 3, and the filtered medicine flows out from the inside of the discharge pipe 2. The bottom of the filter tank 1 has a conical structure to facilitate the outflow of the medicine.
