[0039] In order to better understand the natural product separation and purification device provided in the embodiment of the present application, the following first briefly introduces the existing natural product separation and purification device. The extraction of natural products is generally mostly plants. In the plant extraction process, solvents (such as water, alcohol or other organic solvents) are usually used to extract the effective ingredients in the plants. This process usually includes several steps:

[0040] Pre-treatment: Plant materials (such as leaves, roots or seeds) are first dried, crushed, etc. to increase their surface area;

[0041] Extraction: The processed plant material is mixed with a solvent and extracted in a tank. This step can be static or dynamic (such as stirring).

[0042] Separation: After extraction, the liquid is filtered or centrifuged to remove solid residues;

[0043] Concentration: Removal of solvent by evaporation or other methods to produce a more concentrated extract.

[0044] Stirring helps to improve the dissolution efficiency and extraction speed of the substance during the extraction process. However, stirring may also cause foam to form. The formation of foam is mainly due to the following reasons: air is introduced into the solvent during stirring, which may cause gas (such as air) to form bubbles in the solution; the plant material may contain surfactants or natural foaming agents, which can reduce the surface tension of the liquid and promote the formation of foam; the increase in temperature and shear force during stirring also contribute to the generation of foam. Foam may affect the effective contact between the liquid and the plant material, thereby reducing the extraction efficiency, and make the separation process more complicated, increasing the difficulty of post-processing. In the prior art, manual processing is generally adopted, and the foam is removed by a skimming device after the stirring stops, or a similar device that directly removes the foam from the outside of the tank, etc. This results in the need to stop the machine during processing, affecting the extraction process. In addition, some plant materials present in the foam will also be removed, affecting the extraction yield.

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Example: See Figure 1 - Figure 8 A natural product separation and purification device comprises a tank body 1 and a stirring device 2 arranged in the tank body 1, the tank body 1 has a cover body 11 on the top, a motor 21 is installed on the top of the cover body 11, the output end of the motor 21 is connected to a reducer, the output end of the reducer is connected to a stirring rod 22, the motor 21 and the reducer drive the stirring and rotating to stir the liquid in the tank body 1, the cover body 11 is provided with a feed port for inputting materials, and the bottom of the side wall of the tank body 1 is provided with a discharge port for outputting materials. The natural product separation and purification device also includes:

[0047] The collecting device 3 comprises an annular cylinder 31, which is mounted on the stirring rod 22 of the stirring device 2. A plurality of collecting chambers 32 distributed in an annular array are provided in the annular cylinder 31. The collecting chamber 32 has an opening 33 at the bottom, and a door plate 34 is provided at the opening 33. The door plate 34 can move in a vertical direction to open and close the opening 33. A "J"-shaped collecting plate 35 is also provided at the bottom of the collecting chamber 32. A sealing piston 36 is slidably connected in the collecting chamber 32, and the sealing piston 36 is connected to a first driving member 4 for driving it to slide along the inner wall of the collecting chamber 32.

[0048] The annular cylinder 31 rotates between a first position and a second position. During the rotation from the first position to the second position, the sealing piston 36 moves from the top of the collecting chamber 32 to the middle of the collecting chamber 32, and the door plate 34 moves to an open state. During the rotation from the second position to the first position, the door plate 34 moves to a closed state, and the sealing piston 36 moves to the top of the collecting chamber 32. During the rotation of the annular cylinder 31, the collecting plate 35 always guides the foam to the opening 33.

[0049] It should be noted that, in the process of the collecting plate 35 rotating with the annular cylinder 31, its bottom is in contact with the liquid surface or partially below the liquid surface. As the collecting plate 35 rotates, it will drive the foam to move, and the foam will gather toward the opening 33 under the action of the collecting plate 35. Figure 4 and Figure 5 As shown, Figure 5 The direction indicated by the middle arrow is its rotation direction; the collecting plate 35 has a curved section and a straight section, the curved section is located on the side of the door plate 34, and the straight section is located on the outside of the door plate 34, and the inclination direction of the straight section is toward the rotation direction of the annular cylinder 31, so that during the rotation, the foam moves along the side wall of the straight section and finally gathers below the opening 33. It is worth mentioning that when the lower end of the collecting plate 35 is below the liquid level, the liquid will also be driven by the rotation of the collecting plate 35 and move to the bottom of the opening 33 under the action of the collecting plate 35. Since the foam floats above the liquid surface, some foams with poor fluidity can be driven by the movement of the liquid, thereby improving the smoothness of the movement of the foam;

[0050] The design of the collecting plate 35 allows the liquid to be driven and assist the foam to move toward the opening 33 when the collecting plate 35 rotates below the liquid surface. This design not only improves the smoothness of the foam movement, but also effectively drives the foam with poor fluidity, thereby improving the overall separation effect.

[0051] In addition, the structural design of the annular cylinder 31, the collecting chamber 32, the sealing piston 36 and the door plate 34 ensures the simplicity of the device and the reliability of operation. The coordinated movement of each component helps to reduce mechanical failures and maintenance requirements, thereby improving the service life and working efficiency of the device.

[0052] By adjusting the rotation position of the annular cylinder 31 and the opening and closing state of the door panel 34, the device can adapt to different types of natural products and processing requirements, so that it has good versatility and flexibility in different application scenarios.

[0053] In one embodiment of the present invention, a specific example of a first driving member 4 is provided:

[0054] The first driving member 4 includes a fixed cylinder 41, which is rotatably connected to the stirring rod 22, and the fixed cylinder 41 is installed below the cover 11 of the tank 1 through a connecting member 42. The outer wall of the fixed cylinder 41 is provided with a first groove 43, and a plurality of first power rods 44 are distributed in an annular array around the fixed cylinder 41. One end of each first power rod 44 is fixedly connected to the top of each sealing piston 36 in a one-to-one correspondence, and the first power rod 44 is slidably connected to the inner wall of the annular cylinder 31. The top of each of the first power rods 44 is fixedly connected to a first convex nail, and each of the first convex nails is slidably connected to the first groove 43.

[0055] Specifically, the first groove 43 is composed of a first curved groove A431 and a first flat groove A432. The first curved groove A431 has a curved section in the shape of a "parabola". It should be noted that the parabola refers to the shape of the first groove 43 when it is unfolded from the side of the fixed cylinder 41. Figure 6 As shown;

[0056] In one embodiment of the present invention, a second groove 45 is further provided on the inner wall of the fixed cylinder 41, and a plurality of second power rods 46 are distributed in an annular array on the inner side of the fixed cylinder 41, one end of the second power rod 46 penetrates the annular cylinder 31 and is slidably connected to the inner wall of the annular cylinder 31, and one end of each second power rod 46 is fixedly connected to one side of each door panel 34 in a one-to-one correspondence, and a second convex nail is fixedly connected to the top of the first power rod 44, and each second convex nail is slidably connected to the second groove 45;

[0057] In one embodiment of the present invention, the second groove 45 is composed of a second curved groove A451 and a second flat groove A452, wherein the second curved groove A451 has a curved section in the form of a "parabola", and the second curved groove A451 corresponds to the first flat groove A432, that is, the projections of the second curved groove A451 and the first flat groove A432 on the same horizontal plane coincide with each other;

[0058] When the annular cylinder 31 rotates, taking the implementation scenario of one of the collecting chambers 32 as an example, when the first convex nail slides in the first flat groove A432, the sealing piston 36 will be in the middle of the collecting chamber 32. At this time, the collecting chamber 32 below the sealing piston 36 will be used to load part of the foam. When the first convex nail moves on the first curved groove A431, the sealing piston 36 will first move upward and then move downward to the initial position under the drive of the first power rod 44.

[0059] When the second protruding nail moves on the second flat groove A452, the door plate 34 will be in a state of closing the opening 33. When the second protruding nail moves on the second curved groove, the door plate 34 will first move downward and then move upward, that is, during the rotation of the annular cylinder 31, the door plate 34 will open once and then close the opening 33. In this process, the opening of the door plate 34 will cause the accumulated foam to move to the top of the door plate 34, and then enter the collection chamber 32 as the door plate 34 is closed.

[0060] In the complete process, when the annular cylinder 31 rotates, the door plate 34 collects the foam gathered at the opening 33 into the collecting chamber 32 by opening and closing, and then the sealing piston 36 in the collecting chamber 32 moves upward, and the collecting chamber 32 at the foam becomes a negative pressure state, so that the foam expands and bursts under this environment;

[0061] By combining the sliding of the sealing piston 36 and the opening and closing action of the door panel 34, precise foam collection control is provided; the sealing piston 36 slides along the wall of the collection chamber 32 through the first driving member 4, and collects foam when the door panel 34 is opened. The door panel 34 is closed after collection, and the sealing piston 36 moves upward to change the collection chamber 32 into a negative pressure state, which helps the expansion and rupture of the foam and improves the efficiency of foam separation.

[0062] It should be understood that the connection position of the first curved groove A431 and the first flat groove A432 and the connection position of the second curved groove A451 and the second flat groove A452 are the first position and the second position.

[0063] In one embodiment of the present invention, the second groove 45 is composed of a second curved groove B453 and a second flat groove B454, and the second curved groove B453 has at least two curved sections that are "parabolic" and interconnected, such as Figure 7 As shown (which is a plan view of the fixed cylinder 41 in the expanded state inside and outside), this embodiment provides another example of the second groove 45. When the second curved groove B453 of the second groove 45 is set, the second convex nail will reciprocate in the second curved groove B453, so that when the first convex nail is located in the first flat groove A432 and moves (that is, the sealing piston 36 is in the middle position of the collecting chamber 32), the door plate 34 reciprocates up and down driven by the second power rod 46, and the foam at the opening 33 is repeatedly pushed into the collecting chamber 32 by the door plate 34, thereby ensuring the single processing volume when the sealing piston 36 moves in the collecting chamber 32, thereby improving the processing efficiency.

[0064] Since during the treatment process, after the foam bursts, there will be content substances and some particles that have not been completely extracted. Most of these substances can enter the extraction liquid as the door panel 34 is opened, but there are still some substances remaining on the inner wall of the collection chamber 32 and the bottom of the sealing piston 36 that cannot return to the extraction liquid. As the treatment time increases, this substance will accumulate in the collection chamber 32 and may affect the treatment efficiency and capacity of the collection device 3. In one embodiment of the present invention, a solution to this problem is further provided: the first groove 43 is composed of a first curved groove B433 and a first flat groove B434, the first curved groove B433 has two "parabolic" and interconnected curved sections, the second groove 45 is composed of a second curved groove C455 and a second flat groove C456, the second flat groove C456 has an inclined section for opening the door panel 34, and the turning point of the inclined section corresponds to the connection point of the two "parabolic" curved sections in the first curved groove B433, and the second curved groove C455 has at least two "parabolic" and interconnected curved sections;

[0065] like Figure 8 As shown, under the setting of the first curved groove B433 and the first flat groove B434 and the second curved groove C455 and the second flat groove C456, when the sealing piston 36 stays in the middle of the collecting chamber 32, the door plate 34 will collect foam by opening and closing multiple times. After the door plate 34 closes the opening 33, the sealing piston 36 first moves upward and then moves downward to the middle position of the collecting chamber 32, and then the sealing piston 36 continues to move downward. At this time, the door plate 34 opens at the same time with the cooperation of the inclined section in the second flat groove C456, and the sealing piston 36 moves downward to the lower end of the collecting chamber 32, thereby scraping off the material remaining on the side wall of the collecting chamber 32. It should be noted that when the length of the collecting chamber 32 can be set longer, the length of the sealing piston 36 can be further increased. When the sealing piston 36 moves to the lower end of the collecting chamber 32, the lower end of the sealing piston 36 can be moved outside the collecting chamber 32 and contact with the extraction liquid below, thereby further cleaning the material on the sealing piston 36.

[0066] In one embodiment of the present invention, the natural product separation and purification device further includes an adjustment mechanism 5, the adjustment mechanism 5 includes a sleeve rod 51, the sleeve rod 51 is slidably connected to the surface of the stirring rod 22, the annular cylinder 31 is fixedly mounted on the surface of the sleeve rod 51, the fixed cylinder 41 is rotatably connected to the sleeve rod 51, the top of the sleeve rod 51 is rotatably connected to an insertion rod 52, and one side of the insertion rod 52 is connected to a second driving member 53 for driving it to move in a vertical direction;

[0067] In one embodiment of the present invention, the second driving member 53 is a cylinder or a hydraulic cylinder or an electric telescopic rod, the piston rod of the cylinder or the piston rod of the hydraulic cylinder or the telescopic rod of the electric telescopic rod is connected to the plug rod 52, and the cylinder body of the cylinder or the cylinder body of the hydraulic cylinder or the cylinder body of the electric telescopic rod is fixedly connected to the top of the cover body 11.

[0068] In one embodiment of the present invention, the connecting member 42 includes a fixed bracket 421, which is installed at the bottom of the cover body 11. The inner wall of the fixed bracket 421 is slidably connected to two sliding rods 422, and one end of the two sliding rods 422 is fixedly connected to the two sides of the top of the fixed cylinder 41 respectively.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
