Description

Technical Field

[0001] This utility model belongs to the field of puerarin production technology, specifically relating to a puerarin production extraction device. Background Technology

[0002] Kudzu root is a traditional Chinese medicine. It is the dried root of *Pueraria lobata*, a plant belonging to the genus *Pueraria* of the legume family. It has the effects of relieving muscle tension and reducing fever, promoting rash eruption, generating fluids and quenching thirst, and raising yang to stop diarrhea. It is mainly used to treat fever due to external pathogens, stiff neck and back pain, incomplete measles eruption, thirst due to febrile diseases, thirst due to yin deficiency, dysentery due to heat, and diarrhea due to spleen deficiency.

[0003] Traditional puerarin extraction equipment often adopts single-machine step-by-step operation. This mode involves frequent material transfer, which is not only time-consuming and labor-intensive, but also has a high risk of solvent exposure, long production cycle, low efficiency, and makes it difficult to achieve large-scale continuous production. In addition, some production processes do not optimize the use and recovery of solvents, or fail to further utilize the effective components remaining in the waste residue after extraction, resulting in waste of raw materials and solvents and increased production costs.

[0025] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0026] An extraction apparatus for producing puerarin includes: an extraction mechanism 1, and a pressure filtration mechanism 2 on one side of the extraction mechanism 1;

[0027] The extraction mechanism 1 includes an extraction box 101. A support frame 102 is fixedly connected to one side of the extraction box 101. A sealing cover 103 is slidably connected to the inner wall of the support frame 102. A rotating paddle 104 is rotatably connected to the surface of the sealing cover 103. A crushing box 109 is fixedly connected to the upper surface of the sealing cover 103. Two crushing rollers 110 are rotatably connected to the inner wall of the crushing box 109. A feed hopper 116 is fixedly connected to the top of the crushing box 109. A connecting valve 115 is fixedly connected to one side of the bottom of the extraction box 101.

[0028] The filter press mechanism 2 includes a filter press frame 201 disposed on one side of the extraction tank 101. A guide plate 202 is fixedly connected to the upper surface of the filter press frame 201. Multiple filter plates 203 are slidably connected to the surface of the guide plate 202. A booster pump 205 connected to the bottom of the filter press frame 201 and communicating with the connecting valve 115 is fixedly connected. A connecting pipe 206 is fixedly connected to the liquid outlet end of the booster pump 205 and communicates with one filter plate 203. A collection hopper 207 is fixedly connected inside the filter press frame 201 and below the filter plate 203. After the raw material is crushed by the crushing roller 110, it falls directly into the extraction tank 101 and is efficiently extracted under the stirring of the rotating paddle 104. The resulting mixture can be sent to the filter press mechanism 2 for rapid separation without manual transfer by the booster pump 205, which reduces material transfer loss and time delay between production links and improves production efficiency. At the same time, effective crushing and stirring significantly increases the dissolution rate and extraction rate of puerarin.

[0029] Specifically, a first servo motor 105 is fixedly connected to the upper surface of the sealing cover 103, and the output shaft of the first servo motor 105 is fixedly connected to the rotating propeller 104.

[0030] In a specific embodiment of this utility model, the first servo motor 105 drives the rotating paddle 104 to stir evenly in the extraction box 101, avoiding local concentration differences and optimizing the diffusion rate of puerarin.

[0031] Specifically, a first gear 106 is rotatably connected to the inner wall of the support frame 102, and a transmission gear plate 107 adapted to the first gear 106 is slidably connected to the inner wall of the support frame 102. The transmission gear plate 107 is fixedly connected to the sealing cover 103. A second servo motor 108 is fixedly connected to the outer surface of the support frame 102, and the output shaft of the second servo motor 108 is fixedly connected to the first gear 106.

[0032] In a specific embodiment of this utility model, the second servo motor 108 drives the first gear 106 to rotate, thereby driving the transmission gear plate 107 to move vertically, thus controlling the opening or closing of the sealing cover 103 and realizing the rapid sealing of the extraction box 101.

[0033] Specifically, a second gear 111 is fixedly connected to one end of each of the two crushing rollers 110, and the two second gears 111 mesh. A third servo motor 112 is fixedly connected to the surface of the crushing box 109, and the output shaft of the third servo motor 112 is fixedly connected to the other end of one of the crushing rollers 110.

[0034] In a specific embodiment of this utility model, the third servo motor 112 drives the active crushing roller 110, which in turn drives the driven crushing roller 110 to rotate in the opposite direction through the meshing second gear 111, thereby shearing and crushing the kudzu root raw material.

[0035] Specifically, a cleaning seat 113 is fixedly connected to both sides of the inner wall of the pulverizing box 109, and a cleaning scraper 114 is fixedly connected to the inner side of the cleaning seat 113.

[0036] In a specific embodiment of this utility model, the cleaning scraper 114 is fixed inside the cleaning seat 113 and contacts the surface of the crushing roller 110, scraping away the adhering fibrous impurities during the rotation process.

[0037] Specifically, an electric cylinder 204 is fixedly connected to the surface of the filter press 201, and the piston rod of the electric cylinder 204 is fixedly connected to a filter press plate 203.

[0038] In a specific embodiment of this utility model, the electric cylinder 204 pushes the filter press plate 203 to slide along the guide plate 202, applying uniform pressure to the filter cake, so that the liquid passes through the filter cloth and enters the collection hopper 207.

[0039] Working principle: Kudzu root raw material enters the crushing box 109 through the feed hopper 116. Two counter-rotating crushing rollers 110 mechanically crush the kudzu root raw material into particles under the drive of the third servo motor 112 and the second gear 111. The crushed raw material falls directly into the extraction box 101 below. The first gear 106 is driven to rotate by the second servo motor 108, which drives the transmission gear plate 107 and the sealing cover 103 to move vertically to close the extraction box 101 and form a sealed environment. Solvents such as ethanol are added to the extraction box 101. The first servo motor 105 drives the rotating paddle 104 to stir and promote the full dissolution of puerarin. After extraction, the connecting valve 115 is opened, and the mixture enters the filter press mechanism 2 under the action of the booster pump 205. The filter press plate 203 moves along the guide plate 202 under the push of the electric cylinder 204, applying pressure to the solid-liquid mixture. The liquid component passes through the filter membrane of the filter press plate 203 and enters the collection hopper 207 below, while the solid residue is intercepted to form a filter.
