Technical Field

[0001] This utility model relates to the technical field of extraction and concentration of active ingredients, and in particular to an extraction and concentration device. Background Technology

[0002] As is well known, industries such as biopharmaceuticals, pigments, food and beverages, and chemicals all require the cooking, extraction, and concentration of solid particulate materials to obtain the desired active ingredients. This involves using extraction kettles, concentration kettles, or other methods to wet solid particulate materials with solvents, thereby dissolving the active ingredients in the solid particulate materials into the solvent.

[0003] For example, a Chinese utility model patent discloses a continuous extraction and concentration device (publication number CN217988418U). It includes an extraction circulation loop and a concentration circulation loop. The extraction circulation loop includes an extraction tank and a solvent recovery tank connected by pipes. The concentration circulation loop includes an extraction tank, a material pump, and a concentration tank connected sequentially by pipes. A condensing device is installed on the pipe connecting the extraction tank and the solvent recovery tank. Through the coordinated extraction circulation loop, concentration circulation loop, and vacuum pump, solvent recycling can be achieved, and low-temperature concentration under negative pressure can be used to rapidly extract concentrated beverage raw materials, reducing the loss of effective components in beverage ingredients.

[0004] However, when the inventors implemented this device, they found the following defects: the effective components in the solid particulate material settle at the bottom of the extraction tank after extraction, which is inconvenient to clean. In addition, the solid particulate material will adsorb some solvent and residual effective components, which will be wasted if it is directly cleaned and discarded. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an extraction and concentration device that improves the ease of cleaning solid particle residues inside the extraction tank while reducing the content of effective components and solvents in the solid particle residues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extraction and concentration device, comprising an extraction tank and a concentration tank, wherein a connecting pipe is installed between the extraction tank and the concentration tank, and the extraction tank and the concentration tank are connected by the connecting pipe; a support filter plate is installed in the lower part of the extraction tank, and a slag removal component that fits the inner diameter of the extraction tank is placed on the support filter plate; the extraction tank is provided with a slag removal port that allows the slag removal component to pass through; the slag removal component includes multiple chain plates that are hinged end to end, and the multiple chain plates form an annular body that fits the inner diameter of the extraction tank; furthermore, the inner bottom of the slag removal port is tangent to the top surface of the support filter plate, and a sealing valve plate is detachably installed at the slag removal port; the width of the slag removal port allows 1-3 chain plates to pass through simultaneously, and the height of the slag removal port is greater than the height of the chain plates; the width of the slag removal port can be appropriately adjusted according to the volume and compressibility of the solid particulate material.

[0007] Preferably, multiple sets of circumferentially distributed electromagnets are installed on the outer wall of the extraction tank near the supporting filter plate, and the chain plate is made of magnetic material; furthermore, the chain plate can be made of stainless steel, or other alloys with magnetic attraction and corrosion resistance.

[0008] Preferably, the slag removal port is provided with a rounded corner inlet, and a roller is rotatably mounted on the chain plate.

[0009] Preferably, the chain plate is provided with through-holes; further, the through-holes can be of the form of strip holes, annular holes, etc., and the corresponding hole type can be appropriately selected according to the shape and size of the extracted solid particulate material; the diameter of the through-holes is smaller than the particle size of the solid particulate material.

[0010] Preferably, the chain plates are made of neodymium iron boron permanent magnets, and the magnetic poles on the side of each chain plate facing the center of the ring are the same; furthermore, the magnetic poles of the electromagnets in the energized state are opposite to the magnetic poles on the side of the chain plate away from the center of the ring.

[0011] Preferably, it also includes a condensation recovery mechanism, which includes a condensation tank, a steam pipe and a liquid collection tank. One end of the steam pipe is connected to the upper part of the extraction tank and the other end of the steam pipe is connected to the bottom of the condensation tank.

[0012] Preferably, a heating coil is installed inside the concentration tank, and a second return pipe is installed between the concentration tank and the collection tank.

[0013] Preferably, it also includes a vacuum pump, the input end of which extends into the upper part of the condenser tank.

[0014] Compared with the prior art, this utility model provides an extraction and concentration device with the following beneficial effects: In this extraction and concentration device, solid particulate material is placed into an extraction tank for extraction of effective components. After extraction, the solid particulate residue settles onto a support filter plate and is located within the extrusion and slag removal component. A set of chain plates is pulled outward through the slag removal port. Due to the small diameter of the slag removal port, the annular body deforms under the pressure of the inner wall of the slag removal port, while each chain plate extrudes the solid particulate residue until it is compressed into strips. This causes the adsorbed solvent and some residual effective components in the solid particulate residue to be squeezed out. After the extrusion and slag removal component is completely withdrawn from the slag removal port, the solid particulate residue inside the pressurized slag removal component is cleaned. This effectively improves the convenience of cleaning solid particulate residue in the extraction tank while reducing the content of effective components and solvents in the solid particulate residue.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1 Please refer to Figure 1-5An extraction and concentration device includes an extraction tank 1 and a concentration tank 2, connected by a connecting pipe 3. A support filter plate 4 is installed in the lower part of the extraction tank 1, and a slag-removing component conforming to the inner diameter of the extraction tank 1 is placed on the support filter plate 4. The extraction tank 1 has a slag-removing port 5 that allows the slag-removing component to pass through. The slag-removing component includes multiple chain plates 6 hinged end-to-end, forming an annular shape conforming to the inner diameter of the extraction tank 1. Furthermore, the bottom of the slag-removing port 5 is tangent to the top surface of the support filter plate 4, and a sealing valve plate is detachably installed at the slag-removing port 5. The width of the slag-removing port 5 allows 1-3 chain plates 6 to pass through simultaneously, and the height of the slag-removing port 5 is greater than the height of the chain plates 6. The width of the slag-removing port 5 can be adjusted appropriately according to the volume and compressibility of the solid particulate material.

[0020] For details, please refer to Figure 1 Multiple sets of circumferentially distributed electromagnets 7 are installed on the outer wall of the extraction tank 1 near the supporting filter plate 4, and the chain plate 6 is made of magnetic material; furthermore, the chain plate 6 can be made of stainless steel, or other alloys with magnetic attraction and corrosion resistance.

[0021] For details, please refer to Figure 4 A rounded inlet 8 is provided at the slag removal port 5, and a roller 9 is rotatably installed on the chain plate 6.

[0022] For details, please refer to Figure 5 The chain plate 6 is provided with through filter holes 10; furthermore, the through filter holes 10 can adopt the shape of strip holes, annular holes or other hole types, and the corresponding hole type can be appropriately selected according to the shape and size of the extracted solid particulate material; the hole diameter of the through filter holes 10 is smaller than the particle size of the solid particulate material.

[0023] Specifically, the chain plate 6 uses neodymium iron boron permanent magnets, and the magnetic poles on the side of each chain plate 6 facing the center of the ring are the same; furthermore, the magnetic poles of the electromagnet 7 in the energized state are opposite to the magnetic poles on the side of the chain plate 6 away from the center of the ring.

[0024] In the extraction and concentration equipment provided in this embodiment, when the extrusion slag removal component is inside the extraction tank 1, the electromagnet 7 is energized. Under the action of the electromagnet 7, each chain plate 6 is attracted to the inner wall of the extraction tank 1, preventing the extrusion slag removal component from moving on its own inside the extraction tank 1, ensuring the regularity of the annular body formed by each chain plate 6, and providing a guarantee for the smooth cleaning of particulate material residue on the subsequent support filter plate 4; the rounded corner inlet 8 and the roller 9 can reduce the frictional resistance between the chain plate 6 and the inner wall of the slag removal port 5, and improve the smoothness of the extrusion slag removal component moving out of the slag removal port 5; the through filter hole 10 allows solvents or other liquid components to pass through, while solid particulate materials are filtered and retained; the chain plate 6 with neodymium iron boron permanent magnet has strong magnetic force, and the same magnetic end faces of each chain plate 6 repel each other, which is conducive to the subsequent formation of a regular annular body by the chain plate 6, and effectively prevents the chain plates 6 from attracting and overlapping each other.

[0025] Example 2 The extraction and concentration equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, it also includes a condensation recovery mechanism, which includes a condenser tank 11, a steam pipe 12, and a liquid collection tank 13. One end of the steam pipe 12 is connected to the upper part of the extraction tank 1, and the other end of the steam pipe 12 is connected to the bottom of the condenser tank 11. The liquid collection tank 13 is located below the condenser tank 11. A first return pipe 14 is installed between the liquid collection tank 13 and the condenser tank 11. A condensation coil 15 is installed inside the condenser tank 11. Refrigerant is injected into the condensation coil 15. A first switch valve is installed on the first return pipe 14.

[0026] A heating coil 16 is installed inside the concentration tank 2, and a second return pipe 17 is installed between the concentration tank 2 and the collection tank 13; a second switch valve is installed on the second return pipe 17; and a heating medium is injected into the heating coil 16.

[0027] It also includes a vacuum pump 18, the input end of which extends into the upper part of the condenser tank 11.

[0028] In the extraction and concentration equipment provided in this embodiment, the steam evaporated in the extraction tank 1 enters the condenser tank 11 through the steam pipe 12 and comes into contact with the condenser coil 15. The steam condenses into water droplets after cooling. After the first switch valve is opened, the condensate enters the collection tank 13 through the first return tank. Meanwhile, the extract in the extraction tank 1 enters the concentration tank 2 through the connecting pipe 3. Under the heating action of the heating coil 16, the extract is heated and concentrated. During this process, both the first and second switch valves are in the open state. The steam generated by heating enters the condenser tank 11 and is condensed and recovered. At the same time, the vacuum pump 18 is started. Under the action of the vacuum pump 18, the gas pressure in the condenser tank 11 decreases, which can accelerate the evaporation of gaseous components in the concentration tank 2 and shorten the concentration time of the extract.

[0029] The extraction and concentration equipment provided by this utility model is used as follows: Solid particulate material is placed into the extraction tank 1 for extraction of effective components. After extraction, the solid particulate residue settles on the support filter plate 4 and is located in the extrusion slag removal component. One set of chain plates 6 is pulled outward through the slag removal port 5. Due to the small diameter of the slag removal port 5, the annular body is deformed under the extrusion action of the inner wall of the slag removal port 5, and each chain plate 6 extrudes the solid particulate residue until the solid particulate residue is extruded into strips, so that the solvent adsorbed in the solid particulate residue and some of the residual effective components are squeezed out. When the extrusion slag removal component is completely pulled out from the slag removal port 5, the solid particulate residue in the pressurized slag removal component is cleaned. The cleaned extrusion slag removal component is put back into the extraction tank 1 through the slag removal port 5. The electromagnet 7 is activated. Under the magnetic attraction of the electromagnet 7 and the repulsive force of each chain plate 6, each chain plate 6 forms a regular circular body and is tightly adsorbed to the inner wall of the extraction tank 1, so that the next solid particulate material extraction operation can be carried out.
