In order to obtain high-purity stevia polyphenols, it is necessary to effectively separate and purify stevia using separation and purification equipment.

[0003] Existing stevia polyphenol separation and purification devices require the separation and purification of stevia polyphenols through highly selective adsorption resin in the separation tank. The separation tank is mostly fixed to the mounting frame by welding or bolts, which is inconvenient to disassemble and clean after use and is cumbersome to operate. In view of this, this solution proposes a stevia polyphenol separation and purification device to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figure 1-5 As shown: Example 1: This utility model provides a device for separating and purifying stevia polyphenols, comprising: Base 1; Support frame 2 is fixedly installed on the top of base 1; Mounting bracket 3, multiple mounting brackets 3 are sleeved on the outer wall of the support bracket 2 away from the base 1; Separation tank 4, multiple separation tanks 4 are arranged on both sides of the mounting frame 3; It should be noted that the support frame 2 is fixedly installed on the top of the base 1, and the outer wall of the support frame 2 is sleeved with multiple mounting frames 3. Multiple separation tanks 4 are set at both ends of the mounting frames 3. The separation tanks 4 are fixedly connected to the mounting frames 3 by a fixing mechanism. The separation tanks 4 are filled with highly selective adsorption resin and quartz sand. Stevia polyphenols are separated and purified by highly selective adsorption resin and quartz sand. By improving the pipeline route and adding necessary valves, multiple separation tanks 4 can be dynamically connected in series or in parallel. The highly selective adsorption resin is loaded into the resin column. After the resin combination loading, the adsorption operation of resin alkali washing (sodium hydroxide) → water washing → acid washing (hydrochloric acid) → alcohol washing (ethanol) is carried out to form a four-column series path to complete the adsorption separation, which improves the separation efficiency of stevia polyphenols and steviol glycosides. Example 2: This utility model provides a fixing mechanism applied to a stevia polyphenol separation and purification device in Example 1. The fixing mechanism is located on the top of the mounting frame 3 and includes a connecting part and a fixing part. The connecting part is fixedly connected to the top of the mounting frame 3, and the fixing part is sleeved with the outer wall of the separation tank 4. The fixing part is used to fix the separation tank 4 and the mounting frame 3.

[0021] Specifically, the connecting part includes a connecting frame 7, and multiple connecting frames 7 are fixedly installed on the top of multiple mounting frames 3 respectively. The side of the multiple connecting frames 7 near the separating tank 4 is inserted and connected to the fixing part. A connecting groove is opened on the top of the connecting frame 7. A locking part is provided on the top of the connecting frame 7. The locking part includes a locking member and a pushing member. The locking member is inserted and connected to the connecting groove. The pushing member is fixedly connected to the end of the locking member away from the connecting frame 7. Specifically, the fixing part includes: The fixing block 6 has one end inserted into the end of the connecting frame 7 near the separating tank 4, and the end of the fixing block 6 near the connecting frame 7 is inserted into the locking part. The two ends of the multiple fixed rings 5 ​​are respectively fixedly connected to the ends of the multiple fixed blocks 6 away from the connecting frame 7, and the inner walls of the multiple fixed rings 5 ​​are sleeved with the outer wall of the separation tank 4. Furthermore, a limiting ring 12 is fitted on the outer wall of the separation tank 4, and the bottom of the limiting ring 12 is fitted and connected to the outer wall of the fixing ring 5. It should be noted that the connecting frame 7 is fixedly installed on the top of the mounting frame 3. The side of the connecting frame 7 closest to the separating tank 4 is inserted and connected to the fixing block 6. The end of the fixing block 6 away from the connecting frame 7 is fixedly connected to the fixing ring 5. The inner wall of the fixing ring 5 is sleeved with the outer wall of the separating tank 4. A limiting ring 12 is sleeved on the outer wall of the separating tank 4. The bottom of the limiting ring 12 is fitted and connected to the outer wall of the fixing ring 5. When the separating tank 4 needs to be installed, the fixing ring 5 is sleeved on the outer wall of the separating tank 4, and the separating tank 4 is pushed to the front end of the connecting frame 7. The movement of tank 4 drives the movement of fixing ring 5, which in turn drives the movement of fixing block 6, allowing fixing block 6 to interlock with connecting frame 7. The weight of separating tank 4 itself drives the movement of limiting ring 12, causing the bottom of limiting ring 12 to fit against the outer wall of fixing ring 5. Limiting ring 12 supports separating tank 4. Through the cooperation of fixing block 6, fixing ring 5 and limiting ring 12, separating tank 4 is fixed to connecting frame 7. Separating tank 4 can be quickly disassembled or installed, reducing the difficulty of operation and improving flexibility. Specifically, the locking component includes a locking rod 8, one end of which passes through the connecting groove and is inserted into and connected to the end of the fixing block 6 near the connecting frame 7, and the end of the locking rod 8 away from the connecting groove is fixedly connected to the pushing component; Specifically, the driving components include: Push plate 9 is fixedly installed at the end of locking rod 8 away from the connecting groove; Pull rod 10 is fixedly installed at the end of the push rod away from the locking rod 8; Furthermore, a spring 11 is provided on the top of the connecting frame 7. One end of the spring 11 is fixedly connected to the top of the connecting frame 7, and the other end of the spring 11 is fixedly connected to the end of the push plate 9 away from the pull rod 10. It should be noted that one end of the locking rod 8 passes through the connecting groove and is inserted into the end of the fixing block 6 away from the connecting frame 7. The end of the locking rod 8 away from the connecting groove is fixedly connected to the push plate 9. The end of the push plate 9 away from the locking rod 8 is fixedly connected to the pull rod 10. The spring 11 is set on the top of the connecting frame 7. One end of the spring 11 is fixedly connected to the top of the connecting frame 7. The other end of the spring 11 is fixedly connected to the end of the push plate 9 away from the pull rod 10. When the separating tank 4 needs to be installed, the pull rod 10 is pulled. The movement of the pull rod 10 drives the push plate 9 to move. The movement of the push plate 9 drives the locking rod 8 to move, thus locking the locking mechanism. The rod 8 moves into the connecting groove, and the fixing ring 5 is fitted onto the outer wall of the separating tank 4. The separating tank 4 is pushed to the front end of the connecting frame 7. The movement of the separating tank 4 drives the fixing ring 5 to move, and the fixing ring 5 drives the fixing block 6 to move, so that the fixing block 6 is inserted and connected to the connecting frame 7. The pull rod 10 is released, and the spring 11 drives the push plate 9 to move. The push plate 9 pushes the locking rod 8 to move, so that the locking rod 8 is inserted and connected to the fixing block 6. The locking rod 8 fixes the fixing block 6, thereby fixing the separating tank 4 to the connecting frame 7. The separating tank 4 can be quickly disassembled or installed, reducing the difficulty of operation and improving flexibility.
