Description

Technical Field

[0001] The invention relates to the field of plant extraction equipment, and in particular to an anti-clogging ultrasonic low-temperature countercurrent extraction production line. Background Art

[0002] Continuous countercurrent (ultrasonic) extraction is a brand-new natural plant extraction equipment, an upgrade to the multifunctional extraction tank. This unit is currently in large-scale domestic use. Whether extracting a single or multiple Chinese herbal medicines, and whether the solvent is water or other organic solvents, there are matching equipment to suit the extraction. During extraction, the relative motion of the solvent and solute ensures efficient dissolution of the active ingredients.

[0003] In the existing ultrasonic low-temperature countercurrent extraction production line, the crushed materials enter the immersion tube through the feeding system during the production process.

The liquid outlet 202 and the liquid inlet 203 are connected to the solvent temporary storage tank 6. The liquid inlet 203 is fixed with a frequency conversion pump 8. The solvent liquid in the solvent temporary storage tank 6 can be circulated through the liquid inlet 203 and the liquid outlet 202 under the drive of the frequency conversion pump 8, so that the solvent liquid can be circulated up and down uninterruptedly in the process of contact between the material and the solvent, so that the solvent and the material are fully in contact. A driving object is provided in the secondary immersion tube 201. The driving shaft 204 for moving the material, and the driving blade 205 is spirally arranged on the driving shaft 204 to drive the material in the immersion tube to move. The driving shaft 204 can be driven to rotate by an existing driving device such as a motor. The rotation of the driving blade 205 can drive the plant material to move toward the slag elevator 3. The direction of material movement is opposite to the movement of the solvent, so that the solvent and the material can be fully contacted. A plurality of ultrasonic generators 206 are arranged on the inner wall of the secondary immersion tube 201. The ultrasonic generator 206 can generate ultrasonic waves and use its characteristics to make the solvent in the solvent quickly enter the plant material, dissolve the components contained in the substance as completely as possible in the solvent, and improve the extraction efficiency of the production line.

[0042] In this embodiment, as shown in the attached Figure 1 , attached Figure 2 As shown, the feeding auger group 5 includes a horizontally arranged transverse auger 502, the feed port 401 of the transverse auger 502 is connected to the bottom of the first-level soaking tank 4, one end of the discharge port 402 of the transverse auger 502 is connected to the top of the vertical auger 501, and the bottom end of the vertical auger 501 is connected to the second-level soaking tube 201. The top wall of the transverse auger 502 is evenly distributed with multiple exhaust ports 23. The exhaust ports 23 are convenient for discharging gas entrained in the material pre-soaking process. Preferably, the exhaust ports 23 are provided with a one-way valve.

[0043] The working principle of the present invention is as follows: the plant material after preliminary crushing is injected into the storage box 20, and the pneumatic vibrator 2101 is started. The pneumatic vibrator 2101 generates vibration and transmits it to the screen 21. The two layers of screens 21 screen the plant material in turn. The material with a larger size that cannot pass through the 10-mesh screen 21 falls into the crushing chamber 22. For the plant material with smaller size, secondary crushing can also be avoided. The crushing roller 2201 in the crushing chamber 22 rotates relatively to squeeze the plant material through the shearing teeth 2202 and the extrusion block 2203. The shearing makes the plant material size meet the requirements. The crushed material is lifted to the top of the first-level soaking tank 4 by the feeder 1 and put into the feeding pipe 1101 group. The spray head 1104 on the feeding pipe 1101 can sprinkle the solvent in the solvent temporary storage tank 6 into the feeding pipe 1 The plant raw materials in 101 are preliminarily soaked, and the electric push rod 904 pushes the limit seat 901 to drive the drive motor A902 and the drive shaft 9 to move downward. The half clutch A903 and the half clutch B1001 are engaged with each other, which can drive the linkage plate 10 to rotate synchronously. When the linkage plate 10 rotates, the stop iron 405 and the contact switch 13 on the extrusion prepreg barrel 403 control the start and stop of the drive motor A902. When the stop iron 405 collides with the contact switch 13, the different prepreg barrels 403 on the linkage plate 10 are respectively connected to the feed port 401 and the discharge port 402 of the first-level soaking tank 4, and the plant raw materials in the feeding pipe 1101 group can fall into the prepreg barrel 403, and the material in the prepreg barrel 403 can also be discharged through the discharge port 402 to the feeding pipe 1101 group connected to the discharge port 402 of the first-level soaking tank 4.

[0044] The electric push rod 904 pushes the limit seat 901 to drive the drive motor A902 and the drive shaft 9 to move upward, the half clutch A903 and the half clutch B1001 are disengaged, the tooth-type half clutch C14 and the tooth-type half clutch D16 are engaged, and the driven shaft 15 rotates forward or reverse with the drive shaft 9. The driven shaft 15 drives the linkage rod 17 to rotate through the mutually meshing spur gears A1501 and B1701. The sliding sleeve 18 on the linkage rod 17 moves up and down under the drive of the thread, driving the sliding rod 702 and the piston plate 701 to move up and down. When the piston plate 701 moves downward, the solvent can be extracted. The temporary storage tank 6 engages the solvent and compresses the air inside the pump barrel 7 into the first-level soaking tank 4 through the one-way valve three 705 and the air inlet 406, blowing the material in the pre-soak barrel 403 connected to the discharge port 402 to fall into the feeding auger group 5. When the piston plate 701 moves upward, it can compress the solvent in the pump barrel 7 into the annular cavity 407 of the first-level soaking tank 4 through the liquid injection port 404. The solvent in the annular cavity 407 can enter the pre-soak barrel 403 through multiple liquid holes 19 at the same time to soak the material in the pre-soak barrel 403. At the same time, the air in the external environment can be extracted into the pump barrel 7 through the one-way valve four 706.

[0045] The feeding pipe 1101 connected to the slide bar 702 moves up and down synchronously with the slide bar 702 to change the volume and length of the feeding pipe 1101 group. The anti-blocking rod 1103 fixed on the feeding pipe 1101 moves with the feeding pipe 1101 connected thereto to dredge the feeding pipe 1101 group to avoid blockage in the feeding pipe 1101 group. A plurality of spray heads 1104 are provided on the outer periphery of the feeding pipe 1101 group at the top of the first-level immersion tank 4. The spray head 1104 is connected to the solvent temporary storage tank 6 through the infusion tube 12. The spray head 1104 can sprinkle the solvent in the solvent temporary storage tank 6 onto the material in the feeding pipe 1101 to preliminarily soak it.

[0046] After pre-soaking in the first-level soaking tank 4, the semi-wet material falls into the feeding auger group 5 and passes through the horizontal auger 502 and the vertical auger 501 in turn before entering the second-level soaking tube 201. The frequency conversion pump 8 can circulate the solvent liquid in the solvent temporary storage tank 6 through the liquid inlet 203 and the liquid outlet 202 under the drive of the frequency conversion pump 8, so that the solvent liquid can be circulated up and down uninterruptedly in the process of contact between the material and the solvent, and the solvent and the material are in full contact. After the plant raw material is fully soaked and extracted, the pushing blade 205 spirally arranged on the pushing shaft 204 pushes the material in the soaking tube to move to the slag elevator 3, and after passing through the slag elevator 3, it is sent to the subsequent processing equipment.
