[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figure 1-4 As shown, the utility model provides a plant extraction, separation and purification device, which includes a frame 3, on which a centrifugal device 1 and an adsorption device 2 are provided. The centrifugal device 1 is used to centrifuge the plant extract material, and the adsorption device 2 is used to purify the centrifuged material.

[0025] The centrifugal device 1 includes a centrifuge 101, which is provided with an inlet and an outlet 102 for feeding and discharging the plant extract material after centrifugation, respectively. The centrifuge 101 includes a centrifuge tank 103, within which is disposed a centrifugal shaft 104. A plurality of centrifugal blades 105 are disposed around the outer periphery of the centrifugal shaft 104.

[0026] In order to optimize the centrifugal force distribution, by reducing the diameter of the centrifugal shaft 104 from top to bottom, more appropriate centrifugal forces can be generated at different positions, thereby optimizing the separation effect of the materials.

[0027] The adsorption device 2 is connected to the discharge port 102 of the centrifuge 101. A feed pipe 201 is provided on the discharge port 102. In order to reduce the resistance encountered by the fluid when passing through, thereby reducing energy consumption, the diameters of the two ends of the feed pipe 201 are larger than the diameter of the middle part of the feed pipe 201.

[0028] In order to enable the adsorption device 2 to perform adsorption better, an adsorption component is provided in the adsorption device 2. The adsorption component includes a discharge plate 203. A plurality of discharge holes 204 are opened on the discharge plate 203, and an adsorbent 205 is provided in each discharge hole 204.

[0029] In order to reduce the fluid pressure of the adsorption component, a slow-flow net 206 is arranged between the adsorption component and the feed pipe 201. The outer periphery of the slow-flow net 206 is fixed on the inner wall of the adsorption tank 202, and the middle part of the slow-flow net 206 can move up and down slightly in the adsorption tank 202. At the same time, the middle of the slow-flow net 206 can be set as a filter net. Partial purification can also be performed while buffering the material to prevent the material from having too strong an impact force and incomplete purification or causing damage to the adsorption component.

[0030] To enhance the purification effect, the adsorption component further includes an isolation plate 207 on which an adsorbent 205 is disposed. The isolation plate 207 is provided with a plurality of through holes 208 so that the material flows out from the through holes 208 after passing through the adsorbent 205 and enters the subsequent process.

[0031] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
