Description

Technical Field

[0001] This utility model relates to the field of Solomon's seal saponin extraction technology, and in particular to a Solomon's seal saponin extraction device. Background Technology

[0002] As a traditional Chinese medicine, Polygonatum contains Polygonatum saponins, which have various pharmacological activities such as anti-fatigue, anti-oxidation, hypoglycemia and immune regulation, and have broad application prospects in the fields of medicine, health products and cosmetics.

[0003] In existing technologies, the extract often contains some incompletely broken Polygonatum residue and other impurities. If these impurities are not effectively removed, the purity of the extracted Polygonatum saponins will be low, affecting the quality and efficacy of subsequent products. Moreover, there are inconveniences in separating the extract from the residue, requiring multiple complex steps, which not only increases the complexity of the operation but also easily leads to the loss of Polygonatum saponins and reduces the extraction rate. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where poor filtration during extraction leads to low extraction purity and inconvenience in separating the extract from the residue, and to propose a device for extracting Polygonatum saponins.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for extracting Polygonatum saponins, comprising an extraction box, a connecting pipe, a crushing box, and a top cover. The top of the extraction box is connected to the crushing box through the connecting pipe. The top cover is fixedly connected to the top of the crushing box. A connecting groove is provided on the inner wall of the extraction box. A permeable plate is slidably connected to the inner wall of the connecting groove. Lifting devices are fixedly connected to both ends of the top of the permeable plate. The lifting devices are fixedly connected to the top of the extraction box. A reaction chamber is provided at the bottom of the extraction box. A filter screen is fixedly connected to the inner wall of the connecting pipe.

[0006] An installation plate is fixedly connected to the outer wall of the crushing box. A motor is fixedly connected to the top of the installation plate. A transmission mechanism is fixedly connected to the output end of the motor. A crushing mechanism is fixedly connected to the side of the transmission mechanism.

[0007] Furthermore, the transmission mechanism includes a drive wheel, a belt is sleeved on the outer surface of the drive wheel, and a driven wheel is sleeved on the end of the belt away from the drive wheel.

[0008] Furthermore, specifically, the crushing mechanism includes a crushing roller and a stirring rod. One end of the crushing roller is fixedly connected to one side surface of the driven wheel, and the other end of the crushing roller is rotatably connected to the inner wall of the crushing box. One end of the stirring rod is fixedly connected to one side surface of the driving wheel, and the other end of the stirring rod is rotatably connected to the inner wall of the crushing box.

[0009] Furthermore, the lifting device includes a connecting frame fixedly connected to the top of the extraction box, and an electric push rod fixedly connected to the bottom of the connecting frame. The telescopic end of the electric push rod passes through the top of the extraction box and is fixedly connected to the top of the seepage plate.

[0010] Furthermore, the top cover is connected to the crushing box by a fixing bolt, and a feed inlet is connected through the top of the top cover.

[0011] Furthermore, a connection port is provided on the outer surface of the extraction box, and a collection box is provided below the connection port. The collection box is fixedly connected to the outer surface of the extraction box, and a liquid outlet pipe is connected through the side of the extraction box.

[0012] Furthermore, a base plate is fixedly connected to the bottom of the extraction box, and a support column is fixedly connected to the bottom of the base plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a filter screen in the connecting pipe and a permeation plate in the extraction box, the material and extract during the extraction process of Polygonatum can be filtered twice. When the Polygonatum raw material enters the extraction box from the crushing box through the connecting pipe, the filter screen can intercept larger particles that are not completely crushed, preventing them from entering the extraction box and affecting the purity of subsequent extraction. During the extraction process, the permeation plate can further filter the extract, effectively blocking undissolved residues, thereby greatly improving the purity of the extract and ensuring the production of high-quality Polygonatum saponin products.

[0015] 2. In this utility model, by setting a permeation plate and a lifting device, after the extraction is completed, the electric push rod is activated. The electric push rod drives the permeation plate to move upward in the connecting groove. The material is squeezed against the inner top of the extraction box, so that the extract after the Polygonatum reacts with the extractant can flow fully into the reaction chamber, thereby achieving efficient separation of the extract and residue and improving the efficiency of the entire extraction process.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a device for extracting Polygonatum saponins, including an extraction box 1, a connecting pipe 2, a crushing box 3, and a top cover 6.

[0025] The following section will explain the specific setup and function of the extraction box 1 and the crushing box 3.

[0026] In this implementation scheme: the top of the extraction box 1 is connected to the crushing box 3 through the connecting pipe 2, the top cover 6 is fixedly connected to the top of the crushing box 3, the inner wall of the extraction box 1 is provided with a connecting groove 11, the inner wall of the connecting groove 11 is slidably connected with a seepage plate 4, the two ends of the top of the seepage plate 4 are fixedly connected with lifting devices 5, the lifting devices 5 are fixedly connected to the top of the extraction box 1, the bottom of the extraction box 1 is provided with a reaction chamber 12, and the inner wall of the connecting pipe 2 is fixedly connected with a filter screen 21.

[0027] A mounting plate 31 is fixedly connected to the outer wall of the crushing box 3. A motor 32 is fixedly connected to the top of the mounting plate 31. A transmission mechanism 33 is fixedly connected to the output end of the motor 32. A crushing mechanism 34 is fixedly connected to the side of the transmission mechanism 33.

[0028] Specifically, the transmission mechanism 33 includes a drive wheel 331, a belt 332 is sleeved on the outer surface of the drive wheel 331, and a driven wheel 333 is sleeved on the end of the belt 332 away from the drive wheel 331.

[0029] The effect achieved by the above components is as follows: after the motor 32 starts, it drives the drive wheel 331 to rotate. The drive wheel 331 transmits power to the driven wheel 333 through the belt 332, realizing the effective transmission of power and providing a stable power source for the crushing mechanism 34.

[0030] Specifically, the crushing mechanism 34 includes a crushing roller 341 and a stirring rod 342. One end of the crushing roller 341 is fixedly connected to one side surface of the driven wheel 333, and the other end of the crushing roller 341 is rotatably connected to the inner wall of the crushing box 3. One end of the stirring rod 342 is fixedly connected to one side surface of the driving wheel 331, and the other end of the stirring rod 342 is rotatably connected to the inner wall of the crushing box 3.

[0031] The effects achieved by the above components are as follows: the driven wheel 333 drives the crushing roller 341 to rotate, which squeezes, grinds and crushes the Polygonatum odoratum. The driving wheel 331 drives the stirring rod 342 to rotate synchronously. The stirring rod 342 continuously stirs the Polygonatum odoratum material, so that the Polygonatum odoratum can be fully crushed by the crushing roller 341 in the crushing box 3, which improves the crushing efficiency and crushing uniformity, and is beneficial to the subsequent saponin extraction.

[0032] Specifically, the lifting device 5 includes a connecting frame 51 fixedly connected to the top of the extraction box 1, and an electric push rod 52 fixedly connected to the bottom of the connecting frame 51. The telescopic end of the electric push rod 52 passes through the top of the extraction box 1 and is fixedly connected to the top of the seepage plate 4.

[0033] The aforementioned components achieve the following effect: by controlling the extension and retraction of the electric actuator 52, the height of the percolating plate 4 within the extraction chamber 1 can be precisely adjusted. During the extraction process, the percolating plate 4 can be lowered to ensure full contact between the crushed Polygonatum and the extraction solvent; after extraction, the percolating plate 4 is raised, causing it to press against the top of the extraction chamber 1, separating the solid and liquid, facilitating subsequent collection and processing of the liquid.

[0034] Specifically, the top cover 6 is connected to the crushing box 3 by a fixing bolt, and the top of the top cover 6 is connected to the feed inlet 7.

[0035] The effects achieved by the above components are as follows: the fixing bolt connection method facilitates the disassembly and installation of the top cover 6, and makes it convenient to clean and maintain the inside of the crushing box 3; the feed port 7 provides a convenient feeding channel for Polygonatum raw materials, and raw materials can be added at any time to ensure the continuity of crushing work.

[0036] Specifically, the outer surface of the extraction box 1 is provided with a connection port 13, and a collection box 14 is provided below the connection port 13. The collection box 14 is fixedly connected to the outer surface of the extraction box 1, and a liquid outlet pipe 17 is connected through the side of the extraction box 1.

[0037] The above components achieve the following effects: the connection port 13 and the collection box 14 are used to receive the solid residue separated from the seepage plate 4, which is convenient for centralized cleaning; the liquid outlet pipe 17 is used to export the liquid containing Polygonatum saponins extracted in the reaction chamber 12 of the extraction box 1, which is convenient for subsequent concentration, purification and other operations.

[0038] Specifically, the bottom of the extraction box 1 is fixedly connected to a base plate 15, and the bottom of the base plate 15 is fixedly connected to a support column 16.

[0039] The effect achieved by the above components is that the base plate 15 and the support column 16 form a stable support structure, providing reliable support for the entire extraction device, ensuring that the extraction box 1 remains stable during operation, and preventing the extraction effect and equipment safety from being affected by shaking.

[0040] Working principle: First, the raw material of Polygonatum is put into the crushing box 3 through the feed port 7. The motor 32 is started and the motor 32 drives the drive wheel 331 to rotate. The drive wheel 331 drives the driven wheel 333 through the belt 332, thereby causing the crushing roller 341 and the stirring rod 342 to rotate respectively, and crushing Polygonatum.

[0041] The crushed Polygonatum enters the extraction chamber 1 through the connecting pipe 2 and is filtered by the filter screen 21, falling onto the percolation plate 4. Next, the percolation plate 4 is lowered, and extraction solvent is added to the extraction chamber 1, where the extraction reaction of Polygonatum saponins takes place in the reaction chamber 12. After extraction, the percolation plate 4 is raised to separate the solid and liquid. The solid residue falls into the collection box 14 through the connecting port 13, while the liquid containing Polygonatum saponins is discharged through the outlet pipe 17 for further processing.
