Description

TECHNICAL FIELD

[0001] The present application relates to the field of extraction devices, in particular to an extraction device and a traditional Chinese medicine decoction piece extraction process. BACKGROUND

[0002] Traditional Chinese medicine decoction pieces refer to medicinal materials and processed products of medicinal materials that can be directly used for dispensing or preparation under the guidance of traditional Chinese medicine theory. Traditional Chinese medicine decoction pieces include partially processed traditional Chinese medicine slices (including sections, blocks, and petals), original shape medicinal decoction pieces, and decoction pieces after cutting (based on processing) and processing. Traditional Chinese medicine decoction pieces are important raw materials for Chinese patent medicines.

[0003] During the preparation of traditional Chinese medicine decoction pieces, the purpose of soaking and extracting the raw materials is to extract the active ingredients in the medicinal materials to enhance their efficacy and bioavailability. Soaking mainly involves soaking traditional Chinese medicinal materials in suitable solvents to fully absorb water, swell, and soften the tissue, making it easier for subsequent extraction and processing. Extraction involves using an extractant to extract the active ingredients in the medicinal materials, allowing them to fully mix with the solvent, thereby achieving separation and purification. Through soaking and extraction, the active ingredients in the medicinal materials can be better extracted, improving the quality and efficacy of traditional Chinese medicine decoction pieces. At the same time, these steps can also help remove impurities and harmful substances, improving the purity and safety of traditional Chinese medicine decoction pieces.

[0004] During the preparation of traditional Chinese medicine decoction pieces, special devices can be designed for soaking and extracting the raw materials, including: a soaking device: a soaking tank is designed, and an appropriate amount of water is added to the tank. Traditional Chinese medicine decoction pieces are placed in the tank and soaked for a certain period of time to allow the medicine to fully absorb water and swell. An extraction device: based on the soaking device, an extraction chamber is designed, which contains an extractant. The soaked traditional Chinese medicine decoction pieces are placed in the extraction chamber, and the active ingredients of the medicine are transferred to the extractant using extraction principles. A separation device: the extracted medicine and extractant are separated, which can be done using centrifugal separation, filtration separation, or sedimentation separation. After separation, a traditional Chinese medicine decoction piece solution containing active ingredients is obtained. A concentration device: the traditional Chinese medicine decoction piece solution obtained after separation is concentrated to increase the concentration of active ingredients. A drying device: the concentrated solution is dried to remove excess water, resulting in dried traditional Chinese medicine decoction pieces.

[0005] Chinese patent application CN116808629A discloses a solvent extraction device for decoction piece soaking, which comprises a plurality of soaking containers, each of which comprises a barrel for containing soaking liquid, a top cover detachably connected to the barrel, a telescopic rod fixedly connected to the top cover and extending into the barrel, and a limiting bearing part mounted at the end of the telescopic rod away from the top cover and used for sending the decoction piece below the surface of the soaking liquid.

[0006] The above patent and prior art also have the following defects:

[0007] Some traditional Chinese medicine raw materials, although cut into blocks, still cannot be soaked with solvent, resulting in slow extraction of internal components, long soaking time, poor extraction effect, and the need for manual pressing of the raw materials to break the skin and internal tissue of the block-shaped raw materials, improving the efficiency and effect of soaking and extraction. However, manual operation is troublesome, time-consuming and labor-intensive, and the efficiency is low. The crushing and grinding device in the prior art can improve the efficiency of transferring internal components of the raw materials to the solution, but excessive crushing of the raw materials will result in a large amount of ash, i.e. suspended useless solid particles, in the solution, making subsequent separation, filtration and concentration more troublesome.

[0023] In summary, the technical effects and advantages of the present application are as follows:

[0024] 1、In the present application, when feeding, the pushing plate drives the extrusion plate and the nail bed to move, the extrusion plate extrudes the raw material, the nail bed pierces the raw material, the surface and internal tissue of the raw material are broken, the internal tissue of the raw material has a large number of cracks formed by extrusion and piercing, the solvent can enter the internal tissue of the raw material through the cracks, the internal components of the raw material are more easily transferred to the solvent in soaking, the extraction effect is improved, the raw material is not excessively damaged and crushed, too much ash is not present in the extraction liquid, and the difficulty of subsequent separation, filtration and concentration is reduced.

[0025] 2. In this invention, the raw material falls onto the support plate. By rotating the rotating plate, there is a specified distance between the rotating plate and the support plate. The rotation of the rotating plate flattens the raw material on the support plate. The specified distance between the rotating plate and the support plate can control the thickness of the raw material on the support plate, so that the extrusion plate squeezes the raw material and the nail bed punctures the raw material more evenly, resulting in better destruction of the raw material structure and better extraction effect.

[0026] 3. In this invention, after the raw material on the support plate is squeezed and pierced, it is lowered to the same level as the support plate by the rotating plate. During the descent of the rotating plate, the flip plate is pushed to rotate, opening the feeding notch on the support plate. The rotating plate pushes the raw material into the extraction tank through the feeding notch. It is more convenient to feed the raw material after it is squeezed and pierced. When the rotating plate is in the flip plate position, it will descend and rotate the flip plate. The raw material on the flip plate will fall into the extraction tank first, so that the rotating plate can descend to the same level as the support plate. It will not be unable to descend to the support plate position due to the obstruction of the raw material. The rotating plate pushes the raw material into the feeding notch. The raw material will not remain on the support plate, and the feeding is more thorough.

[0027] 4. In this invention, when the push plate rises and drives the extrusion plate and the nail bed to rise, the extrusion spring resets, causing the nail bed to move above the extrusion plate, so that the material on the nail bed is pushed off by the extrusion plate, preventing the material from remaining on the nail bed, and ensuring that the nail bed has a better piercing effect on the material in the next action.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0041] ​The feeding assembly 2 comprises a feeding pipe 21, the extruding assembly 3 comprises a pushing plate 31, an extruding plate 32, a nail bed 33, an extruding spring 34 and a bearing plate 35, the flattening assembly 5 comprises a rotating plate 51, the discharging assembly 4 comprises a turning plate 41, the raw material can fall on the bearing plate 35 through the feeding pipe 21, the pushing plate 31 can drive the extruding plate 32 to move vertically, the extruding plate 32 is provided with a through hole corresponding to the nail bed 33, the bearing plate 35 is provided with a through hole corresponding to the nail bed 33, the pushing plate 31 can drive the extruding plate 32 and the nail bed 33 to move downwards, so that the extruding plate 32 abuts against the raw material on the bearing plate 35, then the pushing plate 31 continues to descend and the extruding spring 34 applies pressure to the extruding plate 32, the extruding plate 32 extrudes the raw material, at the same time, the pushing plate 31 drives the nail bed 33 to continue to move downwards, the nail bed 33 penetrates through the extruding plate 32 and pierces into the raw material;

[0042] When the raw material falls on the bearing plate 35 through the feeding pipe 21, the rotating plate 51 rises to keep a specified distance with the bearing plate 35 and rotates, the rotating plate 51 rotates to flatten the raw material on the bearing plate 35, the bearing plate 35 is provided with a discharging gap, the turning plate 41 is rotatably connected in the discharging gap, when the raw material is extruded by the extruding plate 32 and pierced by the nail bed 33, the rotating plate 51 descends to the same horizontal plane with the bearing plate 35 and drives the turning plate 41 to rotate, the rotating plate 51 rotates to drive the raw material on the bearing plate 35 to move, and the raw material is moved to the discharging gap and falls into the extraction tank 1.

[0043] The raw material is put on the bearing plate 35 through the feeding pipe 21, when the raw material falls on the bearing plate 35, the rotating plate 51 rises to keep a specified distance with the bearing plate 35 and rotates, the rotating plate 51 rotates to flatten the raw material on the bearing plate 35, so that the raw material on the bearing plate 35 is more uniform, then the pushing plate 31 descends, the pushing plate 31 drives the extruding plate 32 to descend through the extruding spring 34, the extruding plate 32 descends to abut against the raw material on the bearing plate 35, then the pushing plate 31 continues to move downwards, the extruding spring 34 drives the extruding plate 32, the extruding plate 32 extrudes the raw material, so that the extruded tissue of the raw material is damaged, the pushing plate 31 descends while driving the nail bed 33 to move, when the extruding plate 32 abuts against the raw material, the nail bed 33 descends to penetrate through the through hole, the nail bed 33 pierces the raw material, then the pushing plate 31 rises, the pushing plate 31 drives the nail bed 33 and the extruding plate 32 to rise, the nail bed 33 rises above the extruding plate 32, the extruding plate 32 drives the raw material on the nail bed 33 to separate from the nail bed 33, the rotating plate 51 descends to the same horizontal plane with the bearing plate 35, in the descending process, the rotating plate 51 drives the turning plate 41 to rotate, so that the discharging gap on the bearing plate 35 is opened, the rotating plate 51 rotates to drive the raw material on the bearing plate 35 to move, the raw material is pushed into the extraction tank 1 through the discharging gap, the extraction tank 1 is provided with a solvent, the raw material enters the solvent by soaking the internal components.

[0044] During feeding, the push plate 31 drives the extrusion plate 32 and the nail bed 33 to move. The extrusion plate 32 extrudes the raw material, and the nail bed 33 punctures the raw material, causing the surface and internal structure of the raw material to break. This creates a large number of gaps inside the raw material due to extrusion and puncture, allowing the solvent to enter the raw material through these gaps. This makes it easier for the internal components of the raw material to transfer to the solvent during soaking, improving the extraction effect without excessively damaging or crushing the raw material. This ensures that there is not too much ash in the extract, reducing the difficulty of subsequent separation, filtration, and concentration.

[0045] The raw material falls onto the support plate 35. Through the rotation of the rotating plate 51, there is a specified distance between the rotating plate 51 and the support plate 35. The rotation of the rotating plate 51 flattens the raw material on the support plate 35. The specified distance between the rotating plate 51 and the support plate 35 can control the thickness of the raw material on the support plate 35, so that the extrusion plate 32 extrudes the raw material and the nail bed 33 punctures the raw material more evenly, resulting in better destruction of the raw material structure and better extraction effect.

[0046] After the raw material on the support plate 35 is squeezed and pierced, it descends to the same level as the support plate 35 via the rotating plate 51. During the descent of the rotating plate 51, it pushes the flip plate 41 to rotate, opening the discharge notch on the support plate 35. The rotation of the rotating plate 51 pushes the raw material into the extraction tank 1 through the discharge notch. After the raw material is squeezed and pierced, the discharge is more convenient. When the rotating plate 51 is in the position of the flip plate 41, it descends and rotates the flip plate 41. The raw material on the flip plate 41 will fall into the extraction tank 1 first, so that the rotating plate 51 can descend to the same level as the support plate 35. It will not be unable to descend to the position of the support plate 35 due to the obstruction of the raw material. The rotation of the rotating plate 51 pushes the raw material into the discharge notch. The raw material will not remain on the support plate 35, and the discharge is more thorough.

[0047] When the push plate 31 rises, causing the extrusion plate 32 and the nail bed 33 to rise, the extrusion spring 34 returns to its original position, causing the nail bed 33 to move above the extrusion plate 32. This allows the material on the nail bed 33 to be pushed off by the extrusion plate 32, preventing material residue from remaining on the nail bed 33 and ensuring that the nail bed 33 will have a better piercing effect on the material in the next action.
