[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1-4 The present embodiment provides a separation and filtration device for extracting traditional Chinese medicine, which includes an extraction tank 1, a tank cover 2 installed on the extraction tank 1, a filter cartridge 3 suspended in the extraction tank 1, a lifting and adjusting structure, a screw 7 for connecting the filter cartridge 3 and the lifting and adjusting structure, a through cavity 8 opened on the tank cover 2, and a filter press assembly.

[0030] A drainage pipe is fixedly passed through the corresponding side wall of the extraction tank 1. The Chinese medicine and the solvent are boiled in the extraction tank 1, and the effective ingredients in the Chinese medicine are extracted into the solution and discharged through the drainage pipe.

[0031] The filter cartridge 3 is used to hold Chinese medicine. When the Chinese medicine is extracted, the part of the filter cartridge 3 holding the Chinese medicine is immersed in the liquid, so that the Chinese medicine and the solvent can fully react, and the part of the filter cartridge 3 exposed to the liquid surface plays an interception role, preventing the Chinese medicine from overflowing from the filter cartridge 3 during the extraction process. When the extraction is completed and solid-liquid (Chinese medicine-liquid) separation is required, the filter cartridge 3 can be moved up to leave the liquid surface to achieve it.

[0032] The lifting and lowering adjustment structure includes a bracket 4, a linear motor 5, and a push rod 6 fixedly connected to the output end of the linear motor 5. The bracket 4 is fixedly mounted on the tank cover 2, and the linear motor 5 is fixedly mounted on the bracket 4. The longitudinal axes of the push rod 6 and the screw rod 7 are located on the same vertical line, and the push rod 6 is arranged vertically through the bracket 4. The push rod 6 is provided with an inner screw groove for positioning the screw rod 7, and the upper end of the screw rod 7 is screwed into the push rod 6 through the inner screw groove, and the lower end of the screw rod 7 is vertically fixedly connected to the center of the filter cartridge 3.

[0033] In this embodiment, the height of the filter cartridge 3 is adjusted based on the lifting and adjusting structure. When Chinese medicine extraction is performed, the lifting and adjusting structure adjusts the filter cartridge 3 so that the Chinese medicine contained therein is submerged in the solution. When solid-liquid separation is performed, the lifting and adjusting structure adjusts the filter cartridge 3 so that it leaves the solution. The specific lifting process is as follows: the linear motor 5 drives the push rod 6 to drive the filter cartridge 3 connected by the screw rod 7 to move vertically. The screw rod 7 and the push rod 6 are threadedly connected and can be disassembled to remove the medicine residue.

[0034] The filter press assembly includes a pressure plate 9 located at the center of the through cavity 8, a rod cavity 10 provided on the pressure plate 9 for passing the push rod 6, two sets of pull rods 11 provided on the pressure plate 9, and a stop plate 12 fixedly installed on the corresponding pull rods 11. The through cavity 8 is used to pass the filter cartridge 3. In addition, the pressure plate 9 is pulled up to leave the tank cover 2. At this time, the completely leaked through cavity 8 can also serve as a feed channel to replenish the Chinese medicine into the filter cartridge 3 for extraction.

[0035] The use process of the filter press assembly of this embodiment is as follows: when the lifting and adjusting structure drives the filter cartridge 3 to move upward, the drug residue contacts the pressure plate 9. As the filter cartridge 3 continues to move upward, the distance between the pressure plate 9 and the filter cartridge 3 becomes smaller. At this time, the drug residue between the two is squeezed, and the residual drug liquid in the drug residue is fully squeezed out.

[0036] An annular space is formed between the pressure plate 9 and the tank cover 2, and the diameter of the pressure plate 9 is the same as the inner diameter of the filter cartridge 3. When the filter cartridge 3 moves up to partially expose the tank cover 2, the pressure plate 9 is located in the filter cartridge 3. The two groups of pull rods 11 are horizontally arranged at the corresponding two sides of the push rod 6, and the lower end of the pull rod 11 is vertically fixed on the pressure plate 9. The bracket 4 is provided with a guide cavity for passing the pull rod 11, and the upper end of the pull rod 11 is vertically penetrated through the bracket 4 through the guide cavity. A drawing groove is provided on the limit plate 12, and the lower surface of the limit plate 12 is in contact with the upper surface of the bracket 4. It should be noted that when performing filter pressing, the limit plate 12 needs to be pressed down all the time to prevent the pressure plate 9 from being displaced by the upward force of the filter cartridge 3, so as to ensure that the pressure plate 9 always squeezes the dregs. In other embodiments, reinforcement measures can also be provided, such as inserting a piston sleeve into the guide cavity to fix the pull rod 11 to prevent the pressure plate 9 from moving up, which will not be described in detail here.

[0037] In summary, the separation and filtration device of this embodiment has the following advantages compared with traditional Chinese medicine processing tools: the separation and filtration device of this embodiment can be directly used in the extraction and processing of Chinese medicine, and plays the role of containing Chinese medicine for extraction of effective ingredients. At the same time, solid-liquid separation can be directly performed after extraction, and the separation process can ensure that the residual liquid in the medicine residue is fully squeezed out. It is rich in functions and does not require the use of filtering tools after extraction. It has excellent promotion prospects.
