Description

Technical Field

[0001] This invention relates to the field of natural product extraction technology, specifically to an extraction device for active ingredients in natural products. Background Technology

[0002] Hard natural product active ingredient extraction equipment is a key piece of equipment in the field of natural product processing, widely used in pharmaceuticals, food, cosmetics and other industries. Its core function is to efficiently extract target active ingredients from hard natural raw materials such as plants and microorganisms. Through a suitable structural design, it can support the broken hard raw materials and provide a stable contact environment for the raw materials and extraction solvents, promoting the release of active ingredients from the raw material tissue and their dissolution in the solvent. At the same time, the equipment must ensure the continuity and stability of the extraction process, realize the full interaction between the raw materials and the solvent, assist in the separation of the residue from the extract, and provide qualified extraction stock solution for subsequent concentration, purification and other processes. Ultimately, it achieves the goal of selectively extracting active ingredients such as flavonoids, alkaloids, and volatile oils from hard natural raw materials, meeting the needs of industrial mass production or precise laboratory extraction.

[0003] For example, patent document CN217430880U discloses an extraction device for separating natural products. When separating natural products using extraction processes, the dissolution rate gradually slows down as the solute concentration in the solution increases, affecting the extraction speed. Stirring to accelerate the dissolution rate, however, can cause the product to pulverize, making it difficult to separate fine residues. This invention solves these problems. The sealed door is opened, a test tube is taken out, and the natural product is placed inside. The extractant enters the test tube, and the surface of the product is gently swirled and washed inside the test tube to dissolve the active ingredients in the extractant without pulverizing the product. Once the test tube is full, the solution is drained from the test tube, and water... The pump circulates and re-injects the solution into the test tube, ensuring that the concentration of the solution in the subsequently injected test tube is always lower than that in the test tube, resulting in a faster extraction speed. The solution is also stirred in the stirring chamber, which improves the dissolution effect. Although the above application has many beneficial effects, it still has the following shortcomings: During use, the broken blades are very prone to settling due to gravity and solvent convection, sticking tightly to the filter screen at the bottom of the device, forming a dense filter cake layer. The tightly packed blades make it difficult for the solvent to penetrate to the bottom raw material, and the active ingredients cannot be fully dissolved and migrated, resulting in incomplete extraction and waste of raw materials. This leads to the need for repeated extraction, resulting in poor efficiency. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a device for extracting active ingredients from natural products.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a natural product active ingredient extraction device, including a cylinder, a discharge port fixedly connected to the bottom end of the cylinder, and an adjustable feeding mechanism provided inside the cylinder; The adjustable feeding mechanism includes an air bladder, the bottom of which has a slot, and a locking ball is movably engaged inside the slot. A pulling rope is fixedly connected to the bottom of the locking ball, and multiple mounting plates are fixedly connected to the pulling rope. A connecting seat is fixedly connected to half of the mounting plates, and a positioning groove is opened inside each connecting seat. A positioning ball is fixedly connected to the other half of the mounting plates at the corresponding position of the connecting seat. The bottom end of the pulling rope is fixedly connected to a net bag, the inside of which is provided with multiple placement slots, and multiple support wires are fixedly connected to each placement slot. A symmetrically arranged closed net is fixedly connected to the net bag, and a connecting rod is fixedly connected to each of the closed nets. A locking rod is slidably connected to the connecting rod.

[0006] Specifically, a sealing cap is threaded to the top of the cylinder, a plugging cap is threaded to the bottom of the discharge port, and the discharge port is in a through-hole state with the cylinder.

[0007] Specifically, the mounting plates are all flexible, the diameter of the opening at the bottom of the slot is smaller than that of the retaining ball, and the retaining ball is rigid.

[0008] Specifically, the connecting seats are all resilient, the bottom opening diameter of the positioning groove is smaller than the diameter of the positioning ball, the positioning balls are all movably engaged inside the corresponding positioning groove, and the positioning balls are all rigidly set.

[0009] Specifically, the placement grooves are located inside the net bag, and the support wires are all resilient and are arranged in an alternating manner inside the placement grooves.

[0010] Specifically, the connecting rods are T-shaped when combined, and the bottom ends of the connecting rods are fixedly connected to a blocking plate. The bottom end of the locking rod abuts against the top ends of the two blocking plates, and a pulling plate is fixedly connected to the locking rod.

[0011] The beneficial effects of this invention are: To prevent the blades from sticking to the bottom and forming a cake layer, the broken blades are independently separated into multiple placement slots by the interlaced tough support wires inside the mesh bag, so that the blades are always in a suspended state. This completely solves the problem of blades sticking to the bottom filter screen due to gravity settling and solvent convection in traditional devices, and ensures smooth solvent penetration. To improve extraction sufficiency and raw material utilization, the leaves are placed in the tank without stacking or obstruction, maximizing the contact area with the extraction solvent. This allows the active ingredients to fully dissolve and migrate, reducing raw material residue and repeated extraction, and avoiding raw material waste. To adapt to different extraction height requirements, the length of the pulling rope can be flexibly adjusted through the interlocking of the positioning ball and the positioning groove, thereby changing the suspension height of the net and the blades in the solvent, meeting the raw material placement requirements under different extraction stages and different solvent volumes, and enhancing the adaptability of the device. The toughness of the support wire and the flexible structure of the mesh can buffer the impact of the solvent during the extraction process, preventing the leaves from breaking further due to violent collisions and producing fine residues, reducing the difficulty of subsequent purification processes, and indirectly improving product purity.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 7 The present invention provides the following technical solutions: A device for extracting active ingredients from natural products includes a cylinder 1, a discharge port 2 fixedly connected to the bottom end of the cylinder 1, and an adjustable feeding mechanism 3 inside the cylinder 1. The adjustable feeding mechanism 3 includes an airbag 31. The bottom end of the airbag 31 is provided with a slot 32. A locking ball 33 is movably engaged inside the slot 32. A pulling rope 34 is fixedly connected to the bottom end of the locking ball 33. Multiple mounting plates 35 are fixedly connected to the pulling rope 34. A connecting seat 36 is fixedly connected to half of the mounting plates 35. A positioning groove 37 is provided inside the connecting seat 36. A positioning ball 38 is fixedly connected to the other half of the mounting plates 35 at the corresponding position of the connecting seat 36. The bottom end of the pull rope 34 is fixedly connected to a net bag 39. The net bag 39 has multiple placement slots 40 inside, and multiple support wires 41 are fixedly connected inside each placement slot 40. A symmetrically arranged closed net 42 is fixedly connected to the net bag 39. A connecting rod 43 is fixedly connected to each closed net 42, and a locking rod 44 is slidably connected to the connecting rod 43.

[0017] A sealing cap 4 is threaded to the top of the cylinder 1, which can seal the top of the cylinder 1. A plugging cap 5 is threaded to the bottom of the outlet 2, which allows the solvent inside the cylinder 1 to be released through the outlet 2 when the plugging cap 5 is removed. The outlet 2 and the cylinder 1 are in a through-hole state. The mounting plates 35 are all flexible. The diameter of the bottom opening of the slot 32 is smaller than that of the retaining ball 33, which is rigid. The connecting seats 36 are all resilient. The diameter of the bottom opening of the positioning groove 37 is smaller than that of the positioning ball 38, and the positioning balls 38 are all movably engaged inside the corresponding positioning groove 37. The positioning balls 38 are all rigid. The movable positioning ball 38 can be pulled out of the positioning groove 37. The placement groove 40 is set at the top and bottom inside the net bag 39. The support wires 41 are all tough and are arranged in a staggered manner inside the placement groove 40. The blade can be placed between the support wires 41, so that the blade can remain independent and suspended in the solvent. The connecting rod 43 is T-shaped when they are combined. The bottom end of the connecting rod 43 is fixedly connected to the baffle plate. The bottom end of the locking rod 44 abuts against the top of the two baffle plates. The locking rod 44 is fixedly connected to the pull plate, which facilitates the upward movement of the locking rod 44.

[0018] In use, rotate the sealing cap 4 off the cylinder 1 and then remove the adjustable feeding mechanism 3 from the cylinder 1. Move the locking rod 44 upward by pulling the plate. When the locking rod 44 is separated from the two connecting rods 43, the connecting rods 43 are no longer fixed by the locking rod 44. At this time, the closed net 42 can be opened to the side by the connecting rods 43, so that the front of the net bag 39 is fully opened. Then, place each piece of hard blade that needs to be extracted for active ingredients into each placement slot 40. The blade needs to be placed between each support wire 41 inside the placement slot 40. At this time, the blade is in an independent suspended state inside the placement slot 40 and does not interfere with each other. Then, reconnect the two closed nets 42 and reconnect the locking rod 44 to the two connecting rods 43. At this point, the specific length of the pull rope 34 can be selected according to the extraction requirements. The adjustment of the length of the pull rope 34 directly affects the height of the blade suspended in the solvent. The adjustable length of the pull rope 34 meets the needs of the blade at different positions in the solvent. Simply pull the pull rope 34 and the mounting plate 35 connected to the positioning ball 38 away from the connecting seat 36. At this time, the positioning ball 38 will squeeze and expand the bottom opening of the positioning groove 37, thereby separating the positioning ball 38 from the positioning groove 37 and separating the positioning groove 37 from the positioning ball 38. Then the pull rope 34 at the corresponding position will no longer be restricted, thus completing the adjustment of the length of the pull rope 34. At this point, the adjustable dispensing mechanism 3 can be returned to the cylinder 1, and a certain amount of extraction solvent can be added to the cylinder 1. The sealing cap 4 can be reset on the cylinder 1. The airbag 31 will be suspended on the solvent level, so that the net bag 39 and the blades will be suspended together. Then the solvent will pass through the outer wall of the net bag 39 and the wall of the placement groove 40, and then come into contact with each blade. At this time, the blades are in an independent and suspended state in the solvent, which can make more sufficient and uniform contact with the solvent, preventing the phenomenon of incomplete extraction caused by the inability of active ingredients to fully dissolve and migrate. After the extraction is completed, the sealing cap 5 can be rotated. At this time, the solvent extracted in the cylinder 1 can be discharged through the discharge port 2. The sealing cap 4 can be removed again, and the adjustable dispensing mechanism 3 can be taken out to unload the material. When it is necessary to separate the airbag 31 and the net bag 39, simply pull the locking ball 33 to squeeze the bottom opening of the locking groove 32 to make the two separate. The operation is extremely convenient.
