Description

Technical Field

[0001] This utility model relates to the field of separation and purification equipment technology, and in particular to a separation and purification equipment for medicinal and edible Chinese herbal medicines. Background Technology

[0002] In the processing of Chinese herbal medicines that are both food and medicine, separation and purification are key steps. Traditional filtration equipment often uses filter screens or filter cloths with fixed pore sizes, which have problems such as unadjustable filtration accuracy, easy clogging, and difficulty in cleaning. For raw materials with different characteristics, it is often necessary to replace filter media of different specifications, which increases production costs and operational complexity. While there are some devices in the existing technology that can adjust the filtration precision, they generally have drawbacks such as complex structure, low adjustment precision, and poor sealing performance. In particular, when processing highly viscous medicinal and edible materials, problems such as filter clogging and loss of effective ingredients are prone to occur.

[0003] Therefore, there is a need to develop a separation and purification device that can flexibly adjust the filtration accuracy, is easy to clean and maintain, and is suitable for processing various medicinal and edible materials. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing traditional Chinese medicine separation and purification equipment, which mostly uses filter screens or filter cloths with fixed pore sizes, resulting in unadjustable filtration accuracy, easy clogging, and difficulty in cleaning. Therefore, this invention proposes a separation and purification device for Chinese medicinal herbs that are both food and medicine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for separating and purifying medicinal herbs that are both food and medicine includes a separation tank for separation and purification. A fixed ring disk is fixedly welded to the inner wall of the separation tank, and a central column is fixedly coaxially to the inner ring of the fixed ring disk. The filter module can be detached and sleeved on the outside of the central column and is used to filter the medicinal and edible herbal medicine solution entering the separation tank to achieve the purpose of separation and extraction.

[0006] Furthermore, the filter module includes multiple stacked filter sheets that can be detachably sleeved on the outside of the central column. The same elastic sealing ring is tightly fitted between two adjacent filter sheets. The bottom of the lowermost elastic sealing ring is tightly fitted with the top of the fixed ring plate. When the filter sheet is pressed by an external force, the gap between the elastic sealing rings is compressed, thereby actively changing the filtration gap between the filter sheets.

[0007] Furthermore, a moving ring disc and a sliding disc are slidably installed on the outer side of the central column. The top of the moving ring disc and the bottom of the sliding disc are fixedly connected by a vertical rod. The bottom of the moving ring disc and the top of the uppermost filter are tightly fitted together. An electric telescopic rod is fixedly installed on the top of the separation tank. The output shaft of the electric telescopic rod extends into the interior of the separation tank and is fixed to the top of the sliding disc by bolts.

[0008] Furthermore, a flange interface is welded to the outside of the separation tank, and the flange interface of the separation tank is sealed and connected to an inlet pipe for introducing the solution of medicinal and edible herbs to be separated and purified into the separation tank.

[0009] Furthermore, a fixing plate is bolted to the outside of the separation tank, and multiple fixing rods arranged in a matrix are fixed to the bottom of the fixing plate. The bottoms of the multiple fixing rods extend to the bottom of the separation tank and are fixed to the same fixing seat. The fixing seat is stably placed on the ground to provide stable support for the separation tank.

[0010] Furthermore, the bottom of the separation tank is sealed with a drain pipe via a flange, and the drain pipe is located above the fixed base.

[0011] In this application, the filter assembly is initially in a relaxed state. When it is necessary to separate and purify the medicinal and edible herbal solution, the electric telescopic rod is first activated to push the sliding plate downward, and the filter assembly is pressed by the moving ring plate. As the pressure increases, the elastic sealing ring is compressed and deformed, so that the gap between the filter plates gradually decreases. Then, the medicinal and edible herbal solution enters the separation tank through the inlet pipe, filling the space around the filter assembly. According to different extraction requirements, the stroke of the electric telescopic rod can be controlled to precisely adjust the size of the filtration gap. Under pressure, the solution passes through the gap of the filter plates, the effective components are separated and extracted, the impurities are intercepted, and the filtered liquid is discharged from the drain pipe at the bottom. After extraction is complete, the electric telescopic rod is lifted upwards, and the elastic sealing ring rebounds to loosen the filter assembly, making it easier to clean the residue. The entire filter module can be removed from the central column for thorough maintenance periodically.

[0012] In this utility model, the medicinal and edible herbal medicine separation and purification equipment can precisely control the clamping force on the filter sheet group by pushing the moving ring disc with an electric telescopic rod. This pressure causes the elastic sealing ring sandwiched between the filter sheets to undergo uniform compression deformation, thereby changing the flow channel gap between the filter sheets. The operator can continuously adjust the filtration accuracy in the range of tens to hundreds of micrometers according to the characteristics of different medicinal materials and extraction requirements, without the need to replace the filter material. In this utility model, the separation and purification equipment for medicinal and edible herbs can more effectively retain target components and remove impurities by optimizing the filtration gap for different medicinal materials. For medicinal and edible materials with high viscosity, the gap can be appropriately increased to reduce clogging, while the gap can be reduced to improve purity when fine filtration is required. In this invention, the elastic sealing ring rebounds, separating the filter elements and creating a larger cleaning gap. When using a reverse rinsing method, the cleaning fluid can fully flow over the surface of all filter elements, effectively removing residues. For deep cleaning, the entire filter module can be easily removed from the central column for individual processing. This design significantly reduces the cleaning workload and downtime.
