Description

Technical Field

[0001] The utility model relates to the technical field of effective cost extraction of traditional Chinese medicine, in particular to an extraction and separation device for the effective component of platycodon saponin. Background Art

[0002] Platycodon grandiflorum is a perennial herbaceous plant of the genus Platycodon grandiflorum in the family Campanulaceae. Its root is a commonly used Chinese medicine with the effects of clearing the lungs and relieving throat pain, removing phlegm and expelling pus. It is used for cough with a lot of phlegm, chest tightness, sore throat, lung abscess and vomiting pus.

[0003] The existing equipment for extracting platycodon saponins and polysaccharides has a low extraction rate. The patent document with application number CN202310286979.2 and titled "Planthocodon Saponins and Polysaccharides Comprehensive Extraction Equipment and Method" discloses a platycodon saponins and polysaccharides extraction equipment and method, specifically: S1: Platycodon is put into the crushing box of the saponin extraction unit for crushing to obtain powder. S2: The powder is put into the first stirring box through the powder inlet of the first stirring box, and ethanol is discharged into the first stirring box through the liquid inlet of the first stirring box and mixed evenly after stirring to obtain the first mixed liquid. S3: The first mixed liquid is discharged into the first extraction tank through the pipeline, and the first microwave generator is turned on to make the first mixed liquid undergo microwave-assisted extraction to obtain the first extraction liquid. The microwave extraction temperature is 60°C, the microwave power is 500W, and the microwave time is 4min. S4: The first extraction liquid is discharged into the first filter through the pipeline for solid-liquid separation to obtain the saponin extract and the first filter residue. S5: The first filter residue is discharged into the drying box through the pipeline for drying to obtain dry material. S6: The dry material is transported to the second stirring box of the polysaccharide extraction unit through a discharge pipe, and water is input through the liquid inlet of the second stirring box and stirred evenly to obtain a second mixed liquid. S7: The second mixed liquid is discharged into the second extraction tank through a pipeline, and the second microwave generator is turned on to subject the second mixed liquid to microwave-assisted extraction to obtain a second extraction liquid. The microwave extraction temperature is 50°C, the microwave power is 300W, and the microwave time is 2min. S8: The second extraction liquid is discharged into the second filter through a pipeline for solid-liquid separation to obtain a polysaccharide extract and a second filter residue. Among them, when it is necessary to extract the polysaccharides in Platycodon grandiflorum, a first filter residue is needed, and the first filter residue needs to be filtered out from the first extraction liquid. In the process of filtering the first extraction liquid using the first filter, since the first filter residue is easy to clog the filter part of the first filter, the filtration efficiency of the first filter residue is low. Before preparing the polysaccharide extract, the first filter residue needs to be dried. If the first filter residue is obtained by filtering the first extraction liquid through a traditional filter, the first filter residue has a large water content and a long drying time, which affects the efficiency of preparing the second extraction liquid.

[0004] In order to solve the problem of low filtration efficiency, the existing technical idea is to make the first extraction liquid precipitate, extract the clear liquid on the upper layer of the first extraction liquid, and extract the clear liquid on the upper layer of the first extraction liquid. The upper clear liquid and the lower precipitation liquid are filtered using different filters respectively. Since the liquid content in the precipitation liquid is small and the solid content of the upper clear liquid is small, the filtration efficiency can be improved. In the prior art, the technical solution disclosed in the patent document with application number CN202222234151.6 and the name "An extraction tank with upper clear liquid extraction function" includes an extraction tank body, an extraction mechanism, a stirring mechanism and a cleaning mechanism. The top of the extraction tank body is provided with an extractant feeding port, the side wall of the extraction tank body is provided with a glass viewing window, and the bottom of the extraction tank body is provided with a drainage pipe. The extraction mechanism is correspondingly arranged above the glass viewing window to ensure that the extraction of the supernatant can be observed from the glass viewing window, so that the operator can adjust the extraction mechanism according to the depth of the supernatant and improve the speed of daily extraction of the supernatant. The extraction mechanism includes an extraction tube, an active pinch wheel, a driven pinch wheel, a pinch wheel bracket and a servo motor. The pinch wheel bracket is arranged at the top of the extraction tank body. The active pinch wheel and the driven pinch wheel are arranged on the pinch wheel bracket. The extraction tube is clamped between the active pinch wheel and the driven pinch wheel. Both the active pinch wheel and the driven pinch wheel are rotatably connected to the pinch wheel bracket. The servo motor is arranged on one side of the pinch wheel bracket. The output shaft of the servo motor is connected to the active pinch wheel drive. The operation of the pinch wheel is controlled by the servo motor, thereby controlling the extraction depth of the extraction tube, and realizing precise control of the extraction of the supernatant. In the process of extracting the upper clear liquid, in order to ensure the movement of the extraction tube, the extraction tube needs to be connected to the hose. However, the service life of the hose is lower than that of the traditional metal conveying pipeline. And after the extraction tube moves for a period of time, the connection between the hose and the extraction tube is prone to leakage or breakage, posing a safety hazard.

[0005] Therefore, it is necessary to improve the existing technology to improve the filtration efficiency and ensure safe production. Utility Model Content
