Description

Technical Field

[0001] This utility model relates to the field of separation and purification, and in particular to a multi-stage membrane separation and purification device for active ingredients of Glycyrrhiza glabra. Background Technology

[0002] Licorice glabra is an important medicinal plant. Its active ingredients (such as glycyrrhizic acid, glycyrrhizin, and glycyrrhizin) have various effects such as anti-oxidation, anti-inflammation, and whitening. Through multi-stage membrane separation technology, impurities in licorice glabra can be removed, and its internal active ingredients can be separated and purified.

[0003] Chinese utility model patent CN202121271738.3 discloses a multi-stage membrane separation, purification, and extraction device for moisturizing and beautifying fructose components. The device includes a housing and an evaporation unit. The housing contains a separation mechanism, and both sides of the separation mechanism are equipped with driving mechanisms, each including a motor. A fixed frame is fixedly connected to one side of the housing, and the left side of the inner wall of the fixed frame is fixedly connected to the surface of the motor via a support frame. This utility model relates to the field of fructose component processing technology. In this multi-stage membrane separation, purification, and extraction device for moisturizing and beautifying fructose components, during separation via a multi-stage membrane, the motor drives a rotating disk to rotate. The rotating disk drives a vertical rod to press against a protrusion, causing the protrusion to move downwards, thereby moving the separation mechanism downwards. A fixed plate presses down against a spring, and the spring's reaction force causes the separation mechanism to return to its original position, thus achieving vertical movement of the separation mechanism, accelerating the liquid's penetration speed, and shortening the extraction time.

[0004] However, the multi-stage membrane separation and purification extraction device described above uses a plate-shaped filter membrane for separation and purification, which results in residues adhering to the surface of the filter membrane after filtration. This requires the filter membrane to be disassembled and cleaned periodically, making it inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a multi-stage membrane separation and purification device for active ingredients of Glycyrrhiza glabra. The main technical problem to be solved is: to provide a multi-stage membrane separation and purification device that can collect the residue after filtration and separation and can quickly process the residue.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-stage membrane separation and purification device for active ingredients of Glycyrrhiza glabra, comprising a main body, a separation mechanism installed inside the main body, a drive mechanism installed on the side of the main body, and a filter mechanism installed at the bottom of the main body. The main body includes a centrifuge chamber, and a motor chamber is fixedly connected to the outer surface of the centrifuge chamber. The separation mechanism includes a separation cover installed inside the centrifuge chamber, and a gear ring is fixedly connected to the outer surface of the separation cover. The drive mechanism includes a motor installed inside the motor chamber, and a rotating shaft is fixedly connected to the output end of the motor. A gear is fixedly connected to the top of the rotating shaft, and the side of the gear meshes with the side of the gear ring. The filter mechanism includes a filter chamber installed at the bottom of the centrifuge chamber. A first filter membrane is installed inside the filter chamber, and a second filter membrane is installed inside the filter chamber, with the second filter membrane located outside the first filter membrane.

[0007] By adopting the above technical solution, through the separation mechanism and the drive mechanism, the licorice liquid to be separated and purified is placed into the separation hood during use. Then, the motor drives the separation hood to rotate. Centrifugal force can perform preliminary filtration of the licorice liquid in the separation hood, leaving large particulate impurities inside the separation hood, which facilitates the collection of large particulate residues after filtration. The liquid part will pass through the separation hood and enter the filtration mechanism for filtration. The licorice liquid after preliminary filtration will enter the interior of the first filter membrane. Through the first filter membrane and the second filter membrane, the licorice liquid can be subjected to ultrafiltration and nanofiltration, allowing the effective components in the licorice liquid to pass through the first filter membrane and the second filter membrane and enter the filtration chamber. The remaining small impurities will remain in the inner cavity of the first filter membrane, thereby enabling rapid collection and treatment of the residues after filtration and separation, reducing the amount of residue in the separation and purification equipment, and facilitating the subsequent separation and purification of the licorice liquid.

[0009] The inner wall of the centrifuge chamber is fixedly connected to a support ring, and the upper surface of the support ring is provided with a first annular groove.

[0010] By adopting the above technical solution, the separation hood is supported by a support ring, which facilitates the rotation of the separation hood within the centrifuge chamber.

[0011] As a further description of the above technical solution:

[0012] The outer surface of the separation cover is fixedly connected to a first flange, which is located below the toothed ring. The lower surface of the first flange is fixedly connected to a first limiting ring, which is located inside the first annular groove.

[0013] By adopting the above technical solution, it is easy for the separation cover to rotate on the support ring.

[0014] As a further description of the above technical solution:

[0015] The top of the centrifuge chamber is fitted with a cover, and a fixing ring is fixedly connected to the lower surface of the cover. A second annular groove is formed on the lower surface of the fixing ring.

[0016] By adopting the above technical solution, the top of the separation hood can be limited and sealed by the top cover, which facilitates the rotation of the separation hood in the centrifuge chamber.

[0017] As a further description of the above technical solution:

[0018] A second flange is fixedly connected to the outer surface of the separation cover. The second flange is located above the toothed ring. A second limiting ring is fixedly connected to the upper surface of the second flange. The second limiting ring is located inside the second annular groove.

[0019] By adopting the above technical solution, it is easy for the separation hood to rotate in the centrifuge chamber.

[0020] As a further description of the above technical solution:

[0021] A connecting tube is fixedly connected to the bottom of the centrifuge chamber. The first filter membrane has a hollow cylindrical structure and an inner cavity is provided inside the first filter membrane. The bottom of the connecting tube is located in the inner cavity.

[0022] By adopting the above technical solution, the first filter membrane is a hollow cylindrical ultrafiltration membrane with a support frame on both its inner and outer surfaces. The first filter membrane can perform ultrafiltration on the pre-filtered licorice liquid, retaining large molecular impurities (such as polysaccharides and proteins) and allowing small molecular active ingredients to pass through. The second filter membrane is a hollow cylindrical nanofiltration membrane with a support frame on both its inner and outer surfaces. The second filter membrane is located outside the first filter membrane and can perform nanofiltration on the licorice liquid after filtration through the second filter membrane, concentrating the target components and further removing small molecular impurities (such as salts and pigments).

[0024] The bottom of the filter chamber is provided with an outlet, which is located below the inner cavity, and the bottom of the filter chamber is equipped with a sealing cover.

[0025] By adopting the above technical solution, opening the sealing cover can clean the inner cavity of the first filter membrane and remove impurities from the first filter membrane.

[0026] By employing the above technical solution, the multi-stage membrane separation and purification equipment for active ingredients of Glycyrrhiza glabra of this utility model has at least the following beneficial effects:

[0027] 1. Compared with existing technologies, this multi-stage membrane separation and purification equipment for active ingredients of Glycyrrhiza glabra utilizes a separation mechanism and a drive mechanism. During use, the Glycyrrhiza glabra liquid to be separated and purified is placed into the separation hood. Then, the motor drives the separation hood to rotate. Centrifugal force can perform preliminary filtration of the Glycyrrhiza glabra liquid in the separation hood, leaving large particulate impurities inside the separation hood. This facilitates the collection of large particulate residues after filtration. The liquid portion passes through the separation hood and enters the filtration mechanism for further filtration. The pre-filtered Glycyrrhiza glabra liquid enters the interior of the first filter membrane. Through the first and second filter membranes, the Glycyrrhiza glabra liquid undergoes ultrafiltration and nanofiltration, allowing the effective components in the Glycyrrhiza glabra liquid to pass through the first and second filter membranes and enter the filtration chamber. The remaining small impurities are left in the inner cavity of the first filter membrane.

The second filter membrane 403 is a hollow cylindrical nanofiltration membrane. The filter membrane has a support frame on both its inner and outer surfaces. The second filter membrane 403 is located outside the first filter membrane 402 and can perform nanofiltration on the licorice liquid after it has been filtered by the second filter membrane 402, concentrating the target components and further removing small molecule impurities such as salt and pigments.

[0038] Working principle: During use, the licorice liquid to be separated and purified is placed into the separation hood 201. Then, the motor 301 drives the separation hood 201 to rotate. Centrifugal force can perform preliminary filtration of the licorice liquid in the separation hood 201, leaving large particulate impurities inside the separation hood 201, which facilitates the collection of large particulate residues after filtration. The liquid part will pass through the separation hood 201 and enter the filtration mechanism 4 for filtration. The licorice liquid after preliminary filtration will enter the interior of the first filter membrane 402. Through the first filter membrane 402 and the second filter membrane 403, the licorice liquid can be subjected to ultrafiltration and nanofiltration, so that the effective components in the licorice liquid can pass through the first filter membrane 402 and the second filter membrane 403 and enter the filtration chamber 401.
