[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a liquid separation device for extracting drug impurities, comprising a workbench 1 and a fixed seat 14, a vertical shell 3 is fixedly connected to the rear side of the top wall of the workbench 1, an input valve pipe 4 is fixedly connected to the middle of the front side of the inner wall of the vertical shell 3, a plurality of extraction tubes 5 are equidistantly connected to the front side of the input valve pipe 4, the tops of the plurality of extraction tubes 5 are connected to a collection box 6, a circulating fan 7 is fixedly connected to the rear side of the vertical shell 3, an extraction end of the circulating fan 7 is connected to an extraction pipe 8, and the top of the extraction pipe 8 is connected to a collecting box 6. A filter box 9, the top of which is connected to a connecting pipe 10, the front end of which is connected to a sealing cover 11, the bottom wall of which is fixedly mounted on the top wall of the collecting box 6, the output end of the circulating fan 7 is connected to a delivery pipe 12, the top of which is connected to the left side of the input valve pipe 4, a plurality of liquid separation test tubes 15 are equidistantly placed on the front side of the fixing seat 14, the tops of the plurality of liquid separation test tubes 15 are fixedly connected to sealing rings 19, the inner walls of the plurality of sealing rings 19 are connected to the bottom ends of the plurality of extraction tubes 5;

[0030] Specifically, by opening the sealing cover 11, the mixture and the solvent are added to the multiple extraction tubes 5. Then, the sealing cover 11 is closed to ensure that the mixture and the solvent are fully contacted and reacted in the extraction tube 5. During the reaction, highly toxic gas will be generated, which poses a potential threat to the environment and operators. In order to solve this problem, we designed a circulating fan 7, which can extract highly toxic gas from the extraction tube 5 when it is necessary to perform deflation work. The highly toxic gas enters the interior of the filter box 9 through the collection box 6 and the connecting pipe 10. The filter box 9 is provided with a high-efficiency filter material, which can effectively remove harmful substances in the highly toxic gas. Under the continuous action of the circulating fan 7, the filtered gas returns to the extraction tube 5 through the conveying pipe 12 and the input valve pipe 4, and continues to react with the solvent. Such a circulation process can speed up the reaction speed of the solvent and the mixture and improve the separation effect. When the reaction is completed, the separated substances are collected by the liquid separation test tube 15. It is convenient for subsequent separation operations. At the same time, this design avoids the retention of highly toxic gases in the room, reduces the risk of environmental pollution, and protects the health of the operators. It not only improves work efficiency, but also effectively protects the health of operators and related personnel.

[0031] Reference Figure 1 and Figure 3 A stabilizing mechanism 2 is provided at the front side of the workbench 1, and the stabilizing mechanism 2 includes an L-shaped plate 201, and the rear side of the L-shaped plate 201 is fixedly connected to the front side of the workbench 1, and an electric telescopic rod 202 is fixedly connected to the middle part of the rear side of the L-shaped plate 201, and the output end of the electric telescopic rod 202 is fixedly connected to a displacement plate 203, and the left and right ends of the front side of the displacement plate 203 are threaded with threaded knobs 204, and the rear ends of the two threaded knobs 204 are threadedly connected with fixing clips 205, and the front side of the fixing seat 14 is provided with a clamping plate 206, and the rear side of the fixing clip 205 is clamped with the front side of the clamping plate 206;

[0032] Specifically, by starting the electric telescopic rod 202, the displacement plate 203 is driven to move forward or backward. The operation of this step is simple and easy, and the flexibility of the electric telescopic rod 202 makes the installation process more convenient. Next, the fixing clamp 205 fixed by the two threaded knobs 204 will move together with the displacement of the displacement plate 203. After completing the above steps, we can separate or engage the clamping plate 206 with the fixing seat 14 through the movement of the fixing clamp 205, and further stabilize the connection between the liquid separation test tube 15 and the extraction tube 5. This design makes the device more stable during the collection process and reduces the risk of incomplete collection due to shaking. It is not only easy to operate, but also effectively improves the experimental efficiency and reduces experimental errors.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The left and right ends of the rear side of the clamping plate 206 are fixedly connected with clamping columns 16, and the left and right ends of the front side of the fixing seat 14 are provided with holes 17, and the rear ends of the two clamping columns 16 are respectively engaged with the corresponding holes 17; the left side of the vertical shell 3 is fixedly connected with a control switch 20, and the control switch 20 is electrically connected with the circulating fan 7 and the electric telescopic rod 202 respectively; the left side of the control switch 20 is provided with a dust cover 21, and the right side of the dust cover 21 is rotatably connected with the left side of the vertical shell 3 through a hinge;

[0034] Specifically, the rear ends of the two clamping columns 16 are respectively engaged with the corresponding holes 17, so that the connection effect between the clamping plate 206 and the fixing base 14 can be improved. The control switch 20 is electrically connected to the circulating fan 7 and the electric telescopic rod 202 respectively, so that the control switch 20 can complete the opening and closing of the device. The dust cover 21 can protect the control switch 20 and prevent accidental touch.

[0035] Reference Figure 1 and Figure 2 The outer wall of the delivery pipe 12 is fixedly installed with a rubber pad 18, and the outer wall of the rubber pad 18 is fixedly connected to the right side of the vertical shell 3; the left and right sides of the workbench 1 are fixedly connected with two connecting plates 22, and the inner walls of the multiple connecting plates 22 are fixedly connected with support columns 13;

[0036] Specifically, the rubber pad 18 makes it easier to protect the connection of the delivery pipe 12, thereby reducing its wear, and the connecting plate 22 and the support column 13 make the device more stable during operation.

[0037] Working principle: When the extraction starts, the sealing cover 11 is opened to add the mixture and the solvent into the multiple extraction tubes 5, and the sealing cover 11 is closed. When it is necessary to deflate, the circulating fan 7 is started so that the highly toxic gas generated in the extraction tube 5 enters the interior of the filter box 9 through the collection box 6 and the connecting pipe 10 for filtration. Through the continuous operation of the circulating fan 7, the filtered gas enters the interior of the extraction tube 5 through the delivery pipe 12 and the input valve pipe 4, thereby accelerating the reaction of the solvent and the mixture. After the reaction is completed, the collection is completed through the liquid separation test tube 15, thereby avoiding the retention of highly toxic gases in the room while ensuring the health of the operator and improving the work efficiency. In addition, by starting the electric telescopic rod 202, the electric telescopic rod 202 drives the displacement plate 203 to move forward or backward, so that the fixing clamp 205 fixedly installed by two threaded knobs 204 is displaced together, so that the clamping plate 206 can be separated or clamped with the fixing seat 14, so that the device can stabilize the connection between the liquid separation test tube 15 and the extraction tube 5, reducing the possibility of shaking during collection and causing incomplete collection.
