Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-Figure 4A liquid separation and filtration device for drug inspection shown in the figure comprises a filter box 1, a filter screen 2 is fixedly arranged in the filter box 1, a liquid outlet is fixedly arranged at the bottom of the filter box 1, two fixed plates 3 are fixedly installed on the inner wall of the side of the filter box 1, the tops of the two fixed plates 3 are provided with hexagonal sliding holes, a plurality of hexagonal sliding holes are slidably provided with hexagonal sliding rods 4, a plurality of hexagonal sliding rods 4 are fixedly installed with knocking blocks 5 at the top ends, a plurality of knocking blocks 5 are fitted with the bottom of the filter screen 2 at the top ends, a movable plate 6 is fixedly installed at the bottom ends of a plurality of hexagonal sliding rods 4, two mounting rotating holes are provided on the side of the filter box 1, a driving shaft 7 is rotatably installed in the two mounting rotating holes, and a plurality of extrusion plates 8 are evenly fixedly installed on the two driving shafts 7 , multiple squeezing plates 8 correspond to the positions of multiple moving plates 6 respectively, and an elastic reset element for squeezing and pushing the knocking block 5 to automatically reset upward is provided on the fixed plate 3, and the elastic reset element includes a reset spring 10 sleeved on the hexagonal slide bar 4, and the two ends of the reset spring 10 are respectively fixedly mounted on the top of the fixed plate 3 and the bottom of the knocking block 5. A support plate is fixedly installed on the side of the filter box 1, and a drive motor 9 is fixedly arranged on the top of the support plate. The output end of the drive motor 9 is fixedly connected to one end of one of the drive shafts 7, and a synchronous rotation unit is commonly connected to the two drive shafts 7, and the other end of one of the drive shafts 7 extends outside the filter box 1 and is connected to a liquid extraction circulation component for circulating and filtering the liquid medicine.

[0023] By means of the above structure, when the driving motor 9 is started, one of the driving shafts 7 will be driven to rotate. Under the action of the synchronous rotation unit, the other driving shaft 7 will be driven to rotate synchronously. The rotation of the driving shaft 7 will drive the extrusion plate 8 to rotate together. When the extrusion plate 8 rotates to contact the top of the movable plate 6, the extrusion plate 8 continues to rotate to squeeze the movable plate 6 to move downward, and then the knocking block 5 can be driven by the hexagonal slide rod 4 to move downward away from the filter screen 2. When the extrusion plate 8 rotates to disengage from the movable plate 6, under the elastic force of the reset spring 10, the knocking block 5 will be squeezed and pushed to reset upward and automatically knock on the filter screen 2, so that the filter screen 2 can vibrate and eject solid impurities blocked in the mesh of the filter screen 2, thereby effectively reducing the situation where the mesh of the filter screen 2 is always blocked and its filtration efficiency becomes low, thereby ensuring the smooth completion of the liquid medicine separation work and having good practicality.

[0024] As a preferred implementation of this embodiment, the synchronous rotation unit includes two transmission pulleys 11 respectively fixedly sleeved on the two driving shafts 7, and a transmission belt 12 is tensioned and sleeved on the two transmission pulleys 11. The advantage of this arrangement is that when one of the driving shafts 7 rotates, it will drive one of the transmission pulleys 11 to rotate. At this time, under the action of the transmission belt 12, the other transmission pulley 11 will be driven to rotate together, and then the other driving shaft 7 can be driven to rotate synchronously, which plays a role of synchronous transmission.

[0025] As a preferred implementation manner of this embodiment, the liquid pumping circulation component includes a liquid pumping cylinder 13 fixedly mounted on the side of the filter box 1, and a liquid pumping tube and a liquid outlet tube are fixedly provided on the liquid pumping cylinder 13. The ends of the liquid pumping tube and the liquid outlet tube extend into the filter box 1, the end of the liquid pumping tube is located directly below the filter screen 2, and the end of the liquid outlet tube is located directly above the filter screen 2.

The driving unit includes a connecting rotating arm 17 fixedly mounted on the end of the driving rotating shaft 7, and an eccentric column 18 is fixedly mounted on the side of the connecting rotating arm 17. A reciprocating frame 19 is fixedly mounted on the end of the horizontal sliding rod 15, and the eccentric column 18 is adaptively arranged in the reciprocating frame 19. The advantage of such a configuration is that when the driving shaft 7 rotates, the eccentric column 18 will be driven to rotate in a circle through the connecting arm 17. The rotation of the eccentric column 18 will drive the reciprocating frame 19 to move back and forth, and then the horizontal slide bar 15 can be used to drive the pumping piston 14 to move back and forth. At this time, with the cooperation of the pumping tube, the outlet tube and the one-way valve 16, the filtered liquid can be re-extracted to the top of the filter screen 2 for re-filtration, which improves the purity and quality of the liquid, is conducive to ensuring the accuracy of subsequent test results, and has better practicality.

[0026] In this embodiment, two convex plates are fixedly installed on the side of the filter box 1, and the sides of the two convex plates close to each other are fixedly installed with a rectangular guide rod 20, and a guide block 21 is slidably sleeved on the rectangular guide rod 20, and the guide block 21 is fixedly installed on the bottom of the reciprocating frame 19. The advantage of this arrangement is that, through the arrangement of the convex plate, the rectangular guide rod 20 and the guide block 21, the reciprocating frame 19 can only move back and forth horizontally, and then the eccentric column 18 and the reciprocating frame 19 can always maintain a linkage state, and the stability is good during operation.

[0027] As a preferred implementation of this embodiment, a matching sealed box cover 22 is movably installed on the top of the filter box 1. The advantage of this arrangement is that during the filtering and separation process, the liquid medicine can be effectively prevented from splashing outside the filter box 1.
