Description

Technical Field

[0001] This utility model relates to the field of deep processing technology of Cistanche deserticola, specifically, to a device for extracting medicinal components from Cistanche deserticola. Background Technology

[0002] Cistanche deserticola is rich in active medicinal components such as phenylethanoid glycosides, iridoid glycosides, polysaccharides, and amino acids. The extraction process typically involves slicing and air-drying the Cistanche deserticola, then processing the dried slices into ultrafine powder (this breaks down cell walls and increases the dissolution rate of active components). Finally, the ultrafine powder is added to an extraction tank, and an extractant is injected. After extraction, the extractant is filtered to remove residue, and the collected filtrate is concentrated to obtain the product concentrate. However, most existing extraction tanks lack internal filters or only have coarse-pore filters, which can only filter large-volume impurities. Since ultrafine powder has a very small particle size, traditional extraction tanks can only discharge it all, relying on an external filter. When the amount of ultrafine powder is large, it easily adheres to the filter membrane of the external filter. Due to the fineness of the ultrafine powder, as it accumulates, the filtration speed decreases or even stops completely.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a Cistanche deserticola medicinal component extraction device that can filter out a portion of ultrafine powder internally, thereby reducing the filtration pressure on the external filter and improving filtration efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a device for extracting medicinal components from Cistanche deserticola, comprising an extraction tank body and a bottom cover. The bottom of the extraction tank body is open, and the bottom cover is closable at the bottom opening of the extraction tank body. A mixed liquid output pipe is provided in the center of the bottom cover, and a hemispherical filter screen is installed in the middle of the inner wall of the bottom cover. The hemispherical filter screen is convex upward, and micropores for filtering ultrafine powder are arranged in the lower middle part of the hemispherical filter screen, while coarse pores capable of passing through ultrafine powder are arranged in the upper middle part of the hemispherical filter screen.

[0006] Beneficial effects: After the solvent completes the extraction of Cistanche deserticola ultrafine powder, let it stand for a while to allow the ultrafine powder to settle to the bottom of the tank. Then, start the external negative pressure device, and the mixed liquid output pipe will filter the mixed liquid in the tank. The micropores in the lower part of the hemispherical filter screen can filter some of the ultrafine powder. When the micropores are blocked, the excess ultrafine powder and solvent will be discharged from the coarse pores in the upper part of the hemispherical filter screen. This can reduce the filtration pressure of the external filter on the one hand, and not affect the normal extraction of the mixed liquid in the tank on the other hand. After the mixed liquid in the tank is drained, open the bottom cover, clean the filtered ultrafine powder, and then it can be reused.

[0007] Based on the above, the bottom cover is recessed downwards into a shallow arc shape, the bottom of the hemispherical filter screen is provided with a flange ring, the inner wall of the bottom cover is provided with an annular mounting platform, and the flange ring is installed on the annular mounting platform by bolts.

[0008] Beneficial effects: The shallow arc design of the bottom cover has virtually no impact on the extraction process of the solvent in the tank, and the position of the hemispherical filter screen is also lower, which is more conducive to the concentration of the mixture towards the center and the reduction of liquid residue at the bottom of the tank compared with the flat bottom structure, thereby making the filtration more complete. The detachable installation method of the hemispherical filter screen facilitates subsequent maintenance and repair.

[0009] Based on the above, the diameter of the hemispherical filter is 1 / 2 of the inner diameter of the extraction tank.

[0010] Beneficial effects: The hemispherical filter is of moderate size, which provides suitable space inside the extraction tank for the deposition of ultrafine powder.

[0011] Based on the above, a spray head is provided on the top of the extraction tank body, and the spray head is used to rinse the inner wall of the extraction tank body and the inner wall of the bottom cover.

[0012] Beneficial effects: The spray head facilitates the rinsing of ultrafine powder adhering to the inner wall of the extraction tank and the ultrafine powder filtered on the inner wall of the bottom cover.

[0013] Based on the above, it also includes a first cylinder and a second cylinder. A cylinder bottom hinge seat is provided on both sides of the waist of the extraction tank body, corresponding to the bottom ends of the first and second cylinders respectively. A tank bottom hinge seat is provided on both sides of the bottom of the extraction tank body. A V-shaped rod is connected to the center of the bottom of the bottom cover via a connecting post. One end of the V-shaped rod is hinged to one of the tank bottom hinge seats. The first cylinder drives the V-shaped rod to rotate, thereby opening or closing the extraction tank body. A rotary locking hook is hinged to the other tank bottom hinge seat. A pressure block is provided at the other end of the V-shaped rod. When the bottom cover is in the closed state, the second cylinder drives the rotary locking hook to rotate, thereby pressing or releasing the pressure block.

[0014] Beneficial effects: The cooperation of the first cylinder, the second cylinder, the rotary locking hook and the V-shaped rod makes the opening and closing operation of the bottom cover simpler. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0021] like Figure 1-4 As shown, a device for extracting medicinal components from Cistanche deserticola includes an extraction tank body 1 and a bottom cover 2. The top of the extraction tank body 1 is provided with a solid material feeding port 3, a solvent spray head 4, and a condensation equipment interface 5. An electric heating jacket 6 is provided on the side wall of the extraction tank body 1. The bottom of the extraction tank body 1 is open. The bottom cover 2 is closable at the bottom opening of the extraction tank body 1. A mixed liquid output pipe 7 is provided in the center of the bottom cover 2. This part is a common structure of existing extraction tanks and does not require any creative effort.

[0022] To reduce the filtration pressure of the external filter, a hemispherical filter screen 8 is installed in the middle of the inner wall of the bottom cover 2. The hemispherical filter screen 8 is convex upward. The lower middle part of the hemispherical filter screen 8 is provided with micropores 81 for filtering ultrafine powder, and the upper middle part of the hemispherical filter screen 8 is provided with coarse pores 82 that can pass through ultrafine powder.

[0023] In practical use, the mixed liquid output pipe 7 is connected to the external filter, which is then connected to the negative pressure device. The condenser is connected to the condenser interface 5. Cistanche deserticola ultrafine powder is added into the tank through the solid material feeding port 3. Solvent (water) is injected into the tank through the solvent spray head 4. The electric heating jacket 6 is started, and after running for a period of time, the extraction is completed. The heating is turned off, and the tank is left to stand for a while to allow the ultrafine powder to settle to the bottom. Then, the external negative pressure device is started, and the mixed liquid output pipe 7 is used to filter the mixed liquid in the tank. The micropores 81 set in the lower part of the hemispherical filter screen 8 can filter some of the ultrafine powder. When the micropores 81 are blocked, the excess ultrafine powder and solvent are discharged from the coarse holes 82 set in the upper part of the hemispherical filter screen 8. This can reduce the filtration pressure of the external filter on the one hand, and not affect the normal extraction of the mixed liquid in the tank on the other hand. After the mixed liquid in the tank is drained, the bottom cover 2 is opened to clean the filtered ultrafine powder, and then it can be reused.

[0024] Preferably, the bottom cover 2 is recessed downwards into a shallow arc shape, and the bottom of the hemispherical filter screen 8 is provided with a flange ring 83. The inner wall of the bottom cover 2 is provided with an annular mounting platform 21, and the flange ring 83 is installed on the annular mounting platform 21 by bolts 17. In use, the shallow arc design of the bottom cover 2 has virtually no impact on the extraction process of the solvent in the tank, and the position of the hemispherical filter screen 8 is also lower. Compared with the flat bottom structure, it is more conducive to the mixture converging towards the center and reducing the liquid remaining at the bottom of the tank, thereby making the filtration more complete. The detachable installation method of the hemispherical filter screen 8 facilitates subsequent maintenance and repair.

[0025] Preferably, the diameter of the hemispherical filter 8 is 1 / 2 of the inner diameter of the extraction tank 1; thus, the extraction tank 1 has suitable space for depositing ultrafine powder.

[0026] To facilitate rinsing the inner wall, a spray head is provided on the top of the extraction tank 1 (since the solvent is water in this embodiment, the solvent spray head 4 can be directly used as the spray head). The spray head is used to rinse the inner wall of the extraction tank 1 and the inner wall of the bottom cover 2, so as to facilitate the cleaning of the ultrafine powder adhering to the inner wall.

[0027] The Cistanche deserticola medicinal component extraction device also includes a first cylinder 9 and a second cylinder 10. A cylinder bottom hinge seat 11 is respectively provided on both sides of the waist of the extraction tank body 1, corresponding to the bottom ends of the first cylinder 9 and the second cylinder 10. A tank bottom hinge seat 12 is respectively provided on both sides of the bottom of the extraction tank body 1. A V-shaped rod 14 is connected to the center of the bottom of the bottom cover 2 via a connecting post 13. One end of the V-shaped rod 14 is hinged to one of the tank bottom hinge seats 12. The first cylinder 9 drives the V-shaped rod 14 to rotate, thereby opening or closing the extraction tank body 1. A rotating locking hook 15 is hinged to the other tank bottom hinge seat 12. A pressure block 16 is provided at the other end of the V-shaped rod 14. When the bottom cover 2 is in the closed state, the second cylinder 10 drives the rotating locking hook 15 to rotate, thereby pressing or releasing the pressure block 16.

[0028] When the bottom cover 2 needs to be closed, the first cylinder 9 extends, and the V-shaped rod 14 drives the bottom cover 2 to rotate inward together until the bottom cover 2 covers the bottom of the extraction tank body 1. Then the second cylinder 10 extends, driving the rotating locking hook 15 to rotate inward until the pressing block 16 is pressed. When the bottom cover 2 needs to be opened, the second cylinder 10 shortens, driving the rotating locking hook 15 to rotate outward and release the pressing block 16. Then the first cylinder 9 shortens, and the V-shaped rod 14 drives the bottom cover 2 to rotate outward together until the bottom cover 2 opens the bottom of the extraction tank body 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
