Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine extraction, and in particular to a device for separating and extracting traditional Chinese medicine. Background Technology

[0002] In the modern production of traditional Chinese medicine, the separation and extraction process directly determines the yield and purity of active ingredients. Traditional extraction devices generally adopt a phased operation mode of dynamic stirring extraction and static mechanical extrusion: the stirring tank achieves dynamic mixing of medicinal materials and solvent through the rotation of blades, but mechanical extrusion pressure cannot be applied simultaneously during the extraction process, resulting in insufficient cell wall rupture of fibrous medicinal materials; while the screw extruder can apply linear pressure of 10-20MPa, its closed structure completely loses the stirring function, resulting in uneven solvent penetration. Utility Model Content

[0003] The purpose of this invention is to provide a device for separating and extracting traditional Chinese medicine, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for separating and extracting traditional Chinese medicine includes an extraction tank, a solvent inlet, a steam inlet, a spiral steam pipe, a filter cylinder, an inclined sliding feed pipe, a slag discharge cover, a hydraulic rod, a telescopic motor, a telescopic rod, a frustum-shaped extrusion seat, a motor, and a stirring device. The extraction tank has a solvent inlet located on its upper left side, and a steam inlet located below the solvent inlet on its left side. A spiral steam pipe is installed around the inside of the extraction tank. A filter cylinder is installed at the lower inside of the extraction tank. An inclined sliding feed pipe is installed on the upper left side of the extraction tank, allowing direct feeding into the top of the filter cylinder after sliding inwards. A slag discharge cover is installed at the bottom center of the filter cylinder via a hydraulic rod. A telescopic motor is installed at the top center of the extraction tank, and a telescopic rod connected to the telescopic motor is installed inside the extraction tank. A frustum-shaped extrusion seat is installed at the bottom of the telescopic rod. A motor is installed on the upper right side of the extraction tank. A stirring device is installed inside the extraction tank and connected to the motor.

[0006] Preferably, the stirring device further includes a drive gear, a hollow rotating shaft, a driven gear, a connecting rod, and a stirring rod. The hollow rotating shaft is installed on the top outer ring of the telescopic rod. A driven gear is integrally formed on the outer circumference of the top of the hollow rotating shaft. The right side of the driven gear meshes with the drive gear, and the drive gear is connected to the motor. Connecting rods are welded and installed on both the left and right sides of the bottom of the hollow rotating shaft. Stirring rods are installed on the bottom outer side of each connecting rod, and the stirring rods are located between the inner wall of the extraction tank and the outer side of the filter screen cylinder.

[0007] Preferably, the device for separating and extracting traditional Chinese medicine further includes a fixing washer and an L-shaped connecting block. A fixing washer is installed around the outer circumference of the hollow rotating shaft. The fixing washer is connected to the top of the extraction tank through the L-shaped connecting block on the left side. The fixing washer also fixes the entire stirring device by supporting the driven gear at the top, thus preventing the stirring device from sliding downward with the telescopic rod.

[0008] The beneficial effects of this utility model are: This utility model is reasonably designed and can simultaneously apply pressure to the medicinal materials during the process of accelerating mixing with the stirring solvent, which greatly improves the extraction efficiency of limited medicinal materials. At the same time, it has the effects of dynamic stirring and static extrusion, thus improving work efficiency. Attached Figure Description

The solvent inlet 2 is located on the upper left side of the extraction tank 1, and the steam inlet 3 is located below the solvent inlet 2 on the left side of the extraction tank 1. A spiral steam pipe 4 is installed around the inside of the extraction tank 1, and a filter screen cylinder 5 is installed at the lower inside of the extraction tank 1. The top of the extraction tank 1... An inclined sliding feed pipe 6 is installed on the left side of the extraction tank 1. After the inclined sliding feed pipe 6 slides inward, it can directly feed material into the top of the filter screen cylinder 5. The bottom of the extraction tank 1 is located at the center of the bottom of the filter screen cylinder 5 and a slag discharge cover plate 7 is installed through a hydraulic rod 8. A telescopic motor 9 is installed at the center of the top of the extraction tank 1, and a telescopic rod 10 connected to the telescopic motor 9 is installed inside the extraction tank 1. A frustum-shaped extrusion seat 11 is installed at the bottom of the telescopic rod 10. A motor 12 is installed on the right side of the top of the extraction tank 1. A stirring device 13 is installed inside the extraction tank 1 and is connected to the motor 12. The stirring device 13 also includes a drive gear 14, a hollow rotating shaft 15, a driven gear 16, a connecting rod 17, and a stirring rod 18. The hollow rotating shaft 15 is installed on the top outer ring of the telescopic rod 10. The driven gear 16 is integrally formed on the outer circumference of the top of the hollow rotating shaft 15. The right side of the driven gear 16 meshes with the drive gear 14, and the drive gear 14 is connected to the motor 12. The connecting rods 17 are welded and installed on both the left and right sides of the bottom of the hollow rotating shaft 15. The stirring rods 18 are installed on the bottom outer side of the connecting rods 17, and the stirring rods 18 are located between the inner wall of the extraction tank 1 and the outer side of the filter screen cylinder 5.

The fixing washer 19 fixes the entire stirring device 13 by supporting the driven gear 16 at the top, thus preventing the stirring device 13 from sliding downward with the telescopic rod 10.

[0014] The working principle of this utility model is as follows: When adding medicinal materials into the extraction tank 1, the inclined sliding feed pipe 6 is first moved inward, and then the medicinal materials are directly added into the filter cylinder 5 through the inclined sliding feed pipe 6. After the raw materials are added, the inclined sliding feed pipe 6 is pulled outward to prevent affecting the rotation of the stirring device 13. The corresponding solvent is added through the solvent inlet 2, and high-temperature steam is connected through the steam inlet 3. The medicinal materials and solvent in the extraction tank 1 are heated through the spiral steam pipe 4. During the extraction process, the frustum-shaped extrusion seat 11 is driven by the telescopic motor 9 to repeatedly extrude the medicinal materials in the filter cylinder 5. At the same time, the stirring device 13 is driven by the motor 12 to rotate, stir the solvent, and accelerate the mixing.

[0015] The stirring device 13 drives the drive gear 14 to rotate via the motor 12. The drive gear 14 drives the hollow rotating shaft 15 connected to the driven gear 16 to rotate. The hollow rotating shaft 15 drives the connecting rods 17 on both sides and the stirring rod 18 to make circular motion on the telescopic rod 10. The stirring rod 18 stirs the solvent between the extraction tank 1 and the filter cylinder 5.
