Description

Technical Field

[0001] The utility model relates to the field of rutin refining and purification, in particular to a rutin refining device. Background Art

[0002] With the development of modern biotechnology and pharmaceutical industry, the extraction and purification process of natural products has received more and more attention. Rutin, as an important flavonoid compound, is widely used in the fields of medicine, food and health products. It has attracted much attention due to its good biological activities such as antioxidant, anti-inflammatory and blood circulation promotion. Traditional rutin extraction and purification methods often involve high temperature treatment or the use of chemical solvents, which may lead to thermal degradation of rutin or solvent residues, affecting its efficacy and safety.

[0003] In order to solve these problems, a new type of rutin refining device came into being. The device uses vacuum freeze-drying technology, which can effectively remove moisture and gaseous impurities at low temperature and vacuum conditions, thereby efficiently purifying and refining rutin. The device has a unique design, including components such as a sealing plate, a vacuum cover, a freeze-drying carrier plate and a storage plate, which ensures the airtightness and safety of the entire refining process. In addition, the structural design of the device makes operation more convenient, facilitates the placement and adjustment of rutin crystals, and improves work efficiency. The application of the vacuum freeze dryer can not only maximize the retention of rutin's active ingredients, but also improve the purity and stability of the product, meeting increasingly stringent industry standards. Therefore, this rutin refining device has important application prospects in the field of natural product processing and represents the development direction of modern, efficient and safe extraction and refining technologies.

[0004] However, when the rutin refining device uses the vacuum freeze-drying technology to purify rutin crystals, the rutin crystals need to be concentrated on the freeze-drying support plate in the vacuum area, and then the vacuum cover needs to completely cover the vacuum area, and then the vacuum cover area needs to be vacuumed to vacuum freeze-dry and purify the rutin crystals in the internal area of the vacuum cover. However, the vacuum cover is mainly sealed on the sealing plate by the sealing gasket on the outer wall of the bottom end. The sealing gasket plays a sealing role during vacuuming to prevent external air from invading the internal area of the vacuum cover. However, the sealing gasket is easily affected by aging, temperature and external force, which will cause gaps to appear at the joint between the sealing gasket and the sealing plate, which will easily cause external air to intrude into the internal area of the vacuum cover during vacuum purification, causing the rutin crystals to be easily contaminated by external air, and also affecting the vacuum purification effect.

A sealing gasket 8 is fixed to the outer wall of the bottom end of the vacuum cover 9, and the bottom end of the sealing gasket 8 can be completely fitted on the outer wall of the top end of the sealing disk 7. A placement foot 1 is provided at the four corners of the bottom end of the freeze-drying and purification chassis 2.

[0030] like Figure 1 、 Figure 2 and Figure 3As shown, a freeze-drying carrier plate 14 is further provided on the top of the sealing plate 7, and the bottom end of the vacuum cover 9 is sleeved on the circular outer part of the freeze-drying carrier plate 14, and the circular inner wall of the sealing gasket 8 is fitted with the circular outer wall of the freeze-drying carrier plate 14. The sealing plate 7 is connected to the interior of the freeze-drying carrier plate 14 with multiple vents, and a plurality of suspended placement blocks 17 are equidistantly provided on the outer wall of the top of the freeze-drying carrier plate 14. A plurality of placement plates 15 are provided on the top of the plurality of suspended placement blocks 17. The plurality of placement plates 15 are equidistantly arranged from bottom to top, and the left and right ends of the plurality of placement plates 15 are fixedly connected by a connecting bracket 16. The plurality of placement plates 15 are all located inside the vacuum cover 9. When vacuum-drying and purifying the rutin crystals, it is necessary to place a plurality of vessels with rutin crystals inside on the plurality of placement plates 15 respectively, and then It is necessary to place multiple storage trays 15 connected by connecting brackets 16 on multiple suspended placement blocks 17 on the top outer wall of the freeze-drying support tray 14, and adjust the position of the storage tray 15 to ensure that the center of the storage tray 15 and the center of the freeze-drying support tray 14 are on the same vertical line. Then, it is necessary to put the vacuum cover 9 on the outside of the multiple storage trays 15 from top to bottom until the bottom end of the sealing gasket 8 at the bottom end of the vacuum cover 9 is close to the top outer wall of the sealing plate 7, and at the same time, the circular inner wall of the sealing gasket 8 is in contact with the circular outer wall of the freeze-drying support tray 14. Then, the interior of the vacuum cover 9 can be vacuumed and freeze-dried for purification. Under the vacuum state, gaseous impurities such as moisture in the rutin crystals can be extracted, thereby freeze-drying and purifying the rutin crystals to achieve the purpose of refining rutin.

[0031] like Figure 1 、 Figure 4 and Figure 5As shown, a sealing encryption device 10 is connected to the top of the left and right ends of the chassis top seat 6. The sealing encryption device 10 includes a positioning slide rail 18, a T-shaped slider 19, a T-shaped slide groove 20, a vertical bracket 21 and a top frame 22. There are two positioning slide rails 18, and the two positioning slide rails 18 are symmetrically arranged on the top outer walls of the left and right ends of the chassis top seat 6. The two positioning slide rails 18 are longitudinally arranged on the chassis top seat 6. T-shaped slide grooves 20 are arranged inside the two positioning slide rails 18, and T-shaped sliders 19 are arranged in the two T-shaped slide grooves 20. Vertical brackets 21 are provided on the tops of the two T-shaped sliders 19. The two vertical brackets 21 are respectively located on the left and right sides of the vacuum cover 9. A top frame 22 is connected between the tops of the two vertical brackets 21. The T-shaped slider 19 can slide back and forth in the T-shaped slide groove 20. The openings at the front and rear ends of the T-shaped slide groove 20 are blocked with metal blocks. The length of the vertical bracket 21 is greater than the length of the vacuum cover 9, and the top frame 22 is located at the top of the vacuum cover 9. On the upper side of the outer wall, after the vacuum cover 9 is sealed to the top of the density disk, the storage tray 15 and the rutin crystallization container placed on the storage tray 15 will be completely covered by the vacuum cover 9. In order to make the vacuum freeze-drying purification more efficient and stable, encryption is performed at the connection between the vacuum cover 9 and the sealing disk 7, and the encryption needs to be achieved using a sealing encryption device 10. Specifically, it is necessary to hold the vertical bracket 21 and pull it forward so that the vertical bracket 21 moves forward in the T-shaped slide groove 20 in the positioning slide rail 18 through the T-shaped slider 19 at the bottom. This will drive the top frame 22 at the top of the two vertical brackets 21 to slide to the upper side of the top of the vacuum cover 9. When the compression encryption disk 24 on the lower side of the vertical bracket 21 is located on the upper side of the center of the vacuum cover 9, stop sliding the vertical bracket 21 so that the compression encryption disk 24 stays directly above the vacuum cover 9. Then, it is necessary to prepare to use the compression encryption disk 24 to apply pressure to the vacuum cover 9 for sealing and encryption.

[0032] like Figure 1 、 Figure 4 and Figure 5As shown, the sealing and encryption device 10 also includes an industrial-type internal threaded cylinder 23, a rotating rod 26, a tightening screw 27 and an anti-sliding block 28. A circular hole is provided inside the center of the top frame 22, and an industrial-type internal threaded cylinder 23 is inserted into the circular hole.

The sealing and encryption device 10 also includes a tightening and encryption disk 24 and a tightening protection pad 25. The tightening and encryption disk 24 is welded to the top of the tightening screw 27, and the tightening and encryption disk 24 is located on the upper side of the top outer wall of the vacuum cover 9. The tightening and encryption disk 24 is pasted and fixed to the outer wall of the bottom end. The tightening and encryption pad 25 is made of soft rubber. When the encryption tightening disk is slid to the top of the vacuum cover 9, it is necessary to hold the anti-sliding block 28 on the top of the tightening screw 27, and then the other hand needs to drive the industrial-type internal threaded cylinder 23 through the rotating rod 26. The inner threaded barrel 23 rotates, and the anti-sliding block 28 at the top of the tightening screw 27 is held, so the tightening screw 27 does not rotate, and the inner threaded barrel 23 of the industrial type will push the tightening screw 27 downwardly through the thread action, which will cause the tightening screw 27 to drive the tightening encryption disk 24 at the bottom end to move downwardly until the tightening encryption disk 24 fits against the outer wall of the top of the vacuum cover 9 through the tightening protection pad 25 at the bottom end, and then continues to rotate, so that the tightening encryption disk 24 can be tightly pressed against the top of the vacuum cover 9 through the tightening protection pad 25, which will continue to generate downward pressure on the vacuum cover 9, so that the sealing gasket 8 at the bottom end of the vacuum cover 9 can fit more tightly on the sealing disk 7, thereby increasing the sealing effect of the sealing gasket 8 between the vacuum cover 9 and the sealing disk 7, so as to prevent the external air from invading and contaminating the rutin crystals during the vacuum purification of the rutin crystals, so as to increase the purification effect of the rutin crystals.
