Description

Technical Field

[0001] This utility model belongs to the field of separation and purification, and in particular relates to a separation and purification device for natural products. Background Technology

[0002] Natural products refer to substances that exist in nature without artificial synthesis or modification, including various secondary metabolites and their derivatives produced in organisms. These natural products can be classified according to different criteria such as source, structure, and properties, such as plant secondary metabolites, microbial metabolites, and marine organism metabolites. The purpose of separation and purification is to separate natural products from complex mixtures and improve their purity for further structural determination, activity research, development, and utilization. Separation and purification is an important part of natural product research and a key step in realizing the development and utilization of natural product resources. It is of great significance for fields such as new drug discovery, functional food, and cosmetic development.

[0003] Comparing with Chinese Patent No. CN221385288U, an extraction device for separating natural products is disclosed, including an extraction tank. A support frame is fixedly installed at the top center of the extraction tank, and a first motor is fixedly installed at the top of the support frame. A rotating shaft is fixedly installed at the bottom of the output shaft of the first motor. The outer surface of the rotating shaft is movably embedded near the top center of the inner wall of the extraction tank. A stirring blade is fixedly installed at the bottom of the rotating shaft. First scrapers are fixedly installed on both outer surfaces of the rotating shaft and on the inner wall of the extraction tank. A first groove is formed at the center of the inner wall of the extraction tank. The outer surfaces of the two first scrapers are slidably connected to the inner surface of the first groove. A feed pipe is fixedly embedded at the top of the extraction tank and near the front side of the first motor. A transparent observation plate is fixedly embedded at the center of the rear side of the extraction tank.

[0004] In extraction, multiple extractions are required to improve the extraction efficiency of natural products. However, the aforementioned patent uses a bottom-drainage method during extraction, which cannot guarantee the first discharge of the extractant when the extractant is the lighter phase, making multiple extractions inconvenient. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a separation and purification device for natural products to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A separation and purification device for natural products includes a mixing device for stirring and mixing an extractant and a mixture, and a discharge device installed on one side of the mixing device for vertical and horizontal suction and discharge of the liquid. The top of the mixing device is provided with a suction device for vertically and vertically suctioning the extractant from above.

[0008] The discharge device includes a discharge pipe, a discharge pump is installed on the discharge pipe, a three-way valve is installed at the top of the discharge pipe, a discharge pipe is installed on one side of the three-way valve, a second control valve is installed on the discharge pipe, and a connecting pipe is installed at the upper end of the three-way valve.

[0009] The suction device includes a lifting tube, a ring suction assembly is provided at the bottom of the lifting tube, and two electric push rods are symmetrically arranged on the front and rear sides of the ring suction assembly.

[0010] Furthermore, the mixing device includes a support frame, an extraction component is disposed on the top of the support frame, and a stirring component is disposed inside the extraction component.

[0011] Furthermore: the ring suction assembly includes an annular tube, and six suction tubes are evenly arranged below the annular tube.

[0012] Furthermore: the rising pipe is threadedly and sealed to the connecting pipe.

[0013] Furthermore: the extraction assembly includes an extraction chamber, with two observation windows symmetrically arranged on the front and rear sides of the extraction chamber, a first liquid inlet pipe arranged on one side of the top of the extraction chamber, a second liquid inlet pipe arranged on one side of the first liquid inlet pipe, a waste discharge pipe arranged at the bottom of the extraction chamber, and a first control valve installed on the waste discharge pipe.

[0014] Furthermore, the stirring assembly includes a motor, and a stirring rod is mounted below the motor.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] 1. By using a dual-position suction and discharge system, the lower discharge is used when the extractant is the heavy phase and the upper discharge is used when the extractant is the light phase, ensuring that the extractant is always discharged first. This makes it easier to add the extractant again for multiple extractions, thereby improving the extraction effect on natural products.

[0017] 2. By adjusting the height of the suction and drainage mechanism, the depth of the upper drainage can be adjusted according to the amount of extractant used, thus adapting to different amounts of extractant.

[0018] 3. By using a ring-shaped suction design, multiple suction tubes are installed below the ring tube for suction, which increases the speed of suction and drainage. Attached Figure Description

[0026] In this embodiment: the mixing device includes a support frame 101, an extraction assembly is provided on the top of the support frame 101, a stirring assembly is provided inside the extraction assembly, the extraction assembly includes an extraction chamber 102, two observation windows 105 are symmetrically arranged on the front and rear sides of the extraction chamber 102, a first liquid inlet pipe 106 is provided on one side of the top of the extraction chamber 102, a second liquid inlet pipe 107 is provided on one side of the first liquid inlet pipe 106, a waste discharge pipe 108 is provided at the bottom of the extraction chamber 102, a first control valve 109 is installed on the waste discharge pipe 108, and the stirring assembly includes a motor 103, a stirring rod 10 is installed below the motor 103. 4. With the support of the support frame 101, the mixture containing natural products is added into the extraction tank 102 through the first inlet pipe 106. The extractant is added into the extraction tank 102 through the second inlet pipe 107. At the same time, the motor 103 drives the stirring rod 104 to rotate and stir the extractant and the mixture, so that the natural products in the mixture are transferred into the extractant. After the mixing is completed, let it stand for a period of time and observe the inside through the observation window 105. When the stratification occurs, first discharge the extractant into the next process, and then open the first control valve 109 to discharge the waste liquid through the waste discharge pipe 108.

[0027] In this embodiment: the discharge device includes a liquid outlet pipe 201, a liquid discharge pump 202 is installed on the liquid outlet pipe 201, a three-way valve 203 is installed at the top of the liquid outlet pipe 201, a liquid discharge pipe 205 is installed on one side of the three-way valve 203, a second control valve 206 is installed on the liquid discharge pipe 205, and a connecting pipe 204 is installed at the upper end of the three-way valve 203. When discharging the extractant, the liquid discharge pump 202 is started. At this time, if the extractant is a heavy phase, the three-way valve 203 is connected to the liquid discharge pipe 205, and the second control valve 206 is opened to discharge the extractant below through the liquid discharge pipe 205 and the liquid outlet pipe 201 in sequence; if the extractant is a light phase, the three-way valve 203 is connected to the connecting pipe 204, so that it is sucked out by the suction device and discharged through the connecting pipe 204 and the liquid outlet pipe 201.

[0028] In this embodiment: the aspiration device includes a lifting pipe 301, a ring suction assembly is provided at the bottom of the lifting pipe 301, and two electric push rods 304 are symmetrically arranged on the front and rear sides of the ring suction assembly. The ring suction assembly includes an annular pipe 302, and six suction tubes 303 are evenly arranged below the annular pipe 302. The lifting pipe 301 is threadedly sealed to the connecting pipe 204. When the extractant is a light phase, during the aspiration process, the electric push rods 304 extend to drive the annular pipe 302 to move downward, so that the bottom of the suction tubes 303 moves with the liquid level until the bottom of the suction tubes 303 reaches the stratification point, and the extractant above is discharged sequentially through the suction tubes 303, the annular pipe 302, the lifting pipe 301, the connecting pipe 204 and the liquid outlet pipe 201.

[0029] Working principle: During use, the mixture containing natural products is added to the extraction tank 102 through the first inlet pipe 106 under the support of the support frame 101. The extractant is added to the extraction tank 102 through the second inlet pipe 107. At the same time, the motor 103 drives the stirring rod 104 to rotate and stir the extractant and the mixture, so that the natural products in the mixture are transferred to the extractant. After mixing, let it stand for a period of time and observe the inside through the observation window 105. When stratification occurs, start the drain pump 202. At this time, if the extractant is the heavy phase, connect the three-way valve 203 to the drain pipe 205 and open the second control valve 206 to discharge the lower extractant into the next process through the drain pipe 205 and the outlet pipe 201 in sequence. If the extractant is a light phase, connect the three-way valve 203 to the connecting pipe 204 to draw in the extractant from the top. Extend the electric push rod 304 to move the annular pipe 302 downward, causing the bottom of the suction tube 303 to move with the liquid level until the bottom of the suction tube 303 reaches the stratification point. Then, discharge the extractant from the top into the next process through the suction tube 303, annular pipe 302, rising pipe 301, connecting pipe 204, and liquid outlet pipe 201. After the extractant is discharged, add the extractant again through the second liquid inlet pipe 107 and repeat the above process for multiple extractions to improve the extraction effect of natural products in the mixture. After multiple extractions and discharge of the extractant, open the first control valve 109 and discharge the waste liquid through the waste discharge pipe 108.
