DETAILED DESCRIPTION

[0029] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Embodiment 1

[0031] Reference Figure 1-Figure 6The present embodiment proposes an enzyme-assisted extraction device for Schisandra lignans. By setting up a disintegrating device 2, the problem of low lignan extraction efficiency caused by the accumulation of Schisandra lignans at the bottom during the reaction is solved. The device includes a top cover 8 detachably mounted on the device 7, and a box cover 1 arranged in the top cover 8. A sliding groove 11 is provided on the box cover 1. Two symmetrical groups of sliding grooves 12 are provided on both sides of the sliding groove 11. Two symmetrical groups of No. 1 limiting rods 13 are fixedly installed in each group of sliding grooves 12, so that the support plate 21 can move more stably. A feeding port 9 connected to a conical filter screen 28 is provided on the filter plate 23. A No. 3 limiting groove 91 is provided on the filter plate 23. Two symmetrical groups of No. 2 limiting rods 92 are fixedly installed in the No. 3 limiting groove 91. A No. 2 spring 93 is sleeved on the No. 3 limit rod 92, so that the L-shaped cover plate 94 can be quickly reset to block the feeding port 9. An L-shaped cover plate 94 slidably connected to the No. 2 limit rod 92 is slidably installed in the No. 3 limit groove 91. The L-shaped cover plate 94 is moved to open the feeding port 9, and the Schisandra chinensis is placed into the conical filter screen 28 through the feeding port 9. A breaking device 2 is installed on the box cover 1 to prevent the Schisandra chinensis from sticking to each other, and a diffusion device 4 is located below the breaking device 2 and stirs the enzyme solution. A stretching device 3 is provided on the box cover 1 and is synchronously transmitted to the diffusion device 4 when driving the breaking device 2. With the cooperation of the breaking device 2 and the stretching device 3, the Schisandra chinensis can be broken up, so that the Schisandra chinensis reacts more fully with the enzyme solution, and the diffusion device 4 makes the enzyme solution more evenly distributed.

[0032] The accumulation of Schisandra chinensis at the bottom can be suspended in the enzyme solution by stirring to make it fully react. However, since the enzyme solution is relatively viscous, it requires a large force to stir it quickly to make the Schisandra chinensis be broken up, which will cause the Schisandra chinensis to break up. When extracting lignans, the solution needs to be filtered multiple times, which affects the extraction efficiency of lignans. If the Schisandra chinensis is wrapped in a filter for reaction, there will be an uneven concentration of the enzyme solution inside and outside the filter, which will also affect the extraction efficiency of lignans. In order to solve this problem, the breaking device 2 includes a support plate 21 slidably installed in the sliding groove 12 and slidably connected to the first limit rod 13. A support tube 22 is fixedly installed on the support plate 21 to support A filter plate 23 is fixedly installed on the tube 22 to facilitate the exchange of enzyme solutions inside and outside the conical filter screen 28. Two symmetrical groups of No. 1 support rods 29 are fixedly installed between the filter plate 23 and the box cover 1. A No. 1 limit groove 24 is provided in the support tube 22. A limit slide bar 25 is slidably installed in the No. 1 limit groove 24. A No. 1 spring 26 is sleeved on the limit slide bar 25 so that the limit slide bar 25 can be quickly reset. A connecting rod 27 is fixedly installed on the bottom end of the limit slide bar 25. A conical filter screen 28 is fixedly connected to the edge of the bottom of the filter plate 23, and the bottom of the conical filter screen 28 is sleeved on the connecting rod 27 to form a closed space. When the limit slide bar 25 slides in the vertical direction of the No. 1 limit groove 24, the connecting rod 27 prompts The conical filter 28 gradually changes from the original conical shape to a flat annular state with the bottom concave inward. When the conical filter 28 is in the conical shape, the schisandra chinensis is concentrated at the bottom of the conical filter, which is convenient for driving all the schisandra chinensis to move when deformation occurs. When the bottom of the conical filter 28 is concave inward, the concentrated schisandra chinensis can be spread out, and the schisandra chinensis that fit each other are no longer fitted by changing their positions. When the conical filter 28 becomes a flat state, its cross-section reaches the maximum state, and the schisandra chinensis are distributed more sparsely, which is convenient for the enzyme solution and the schisandra chinensis to fully react. Under the action of the swing device 5, the support plate 21 is driven to move in the sliding groove 12, and then the limit slide bar 25 is driven by the stretching device 3 to move in the support tube 22 moves upward, spring 1 26 is forced to shrink, the limit slide bar 25 moves upward to drive the connecting rod 27 to move, and the connecting rod 27 drives the bottom of the conical filter 28 to move upward. The conical design of the conical filter 28 can pull the Schisandra chinensis deposited at the bottom of the conical filter 28 to the top of the conical filter 28, which can prevent the Schisandra chinensis from being broken. Since the top of the conical filter 28 is relatively open, the Schisandra chinensis can diffuse in the enzyme solution, and the internal space of the conical filter 28 is reduced, the enzyme solutions inside and outside can be exchanged through the filter plate 23, so that the concentration of the enzyme solutions inside and outside the conical filter 28 is relatively uniform, which avoids the situation where the Schisandra chinensis settles to the bottom during the reaction and causes a low lignan extraction efficiency.

[0033] The stretching device 3 includes a guide wheel 31 fixedly installed on the support tube 22, so that the loss of the connecting rope 33 is reduced. A fixed block 32 is fixedly installed on the box cover 1, and a connecting rope 33 in contact with the guide wheel 31 is fixedly installed between the fixed block 32 and the limiting slide bar 25. The movement of the support plate 21 drives the support tube 22 to move. Since one end of the connecting rope 33 is connected to the fixed block 32 and the position remains unchanged, when the support plate 21 moves, the connecting rope 33 pulls the limiting slide bar 25 to move upward.

[0034] Embodiment 2

[0035] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the disadvantage that the lignan extraction efficiency is low due to the accumulation of Schisandra chinensis at the bottom during the reaction. Since most of the enzyme solution in the conical filter 28 is exchanged with the external enzyme solution through the deformation of the conical filter 28, the enzyme solution just exchanged will still be distributed around the conical filter 28, affecting the extraction of lignans. In order to solve this problem, reference is made to Figure 1-Figure 6 The diffusion device 4 includes two groups of No. 1 support frames 41 fixedly mounted on the filter plate 23, each group of No. 1 support frames 41 is fixedly mounted with a tooth plate 42, and two symmetrical groups of No. 2 support frames 43 are fixedly mounted on the connecting rod 27, and each group of No. 2 support frames 43 is rotatably mounted with a gear 44 meshing with the tooth plate 42, and two groups of connecting shafts 45 symmetrically mounted on the gear 44 and passing through the No. 2 support frame 43, and multiple groups of stirring paddles 46 are evenly mounted on the connecting shaft 45. The connecting rod 27 moves upward to drive the No. 2 support frame 43 to move upward. Under the action of the tooth plate 42 and the gear 44, the No. 2 support frame 43 moves upward so that the gear 44 drives the stirring paddle 46 connected to the connecting shaft 45 to rotate, and the stirring paddle 46 rotates while moving up and down, so as to evenly stir the enzyme solution in the box body 72, thereby avoiding the situation where the enzyme solution is distributed around the conical filter screen 28 and affects the extraction of lignans.

[0036] Embodiment 3

[0037] Due to the limited stirring range of the stirring paddle 46, the enzyme solution exchanged around the filter plate 23 cannot be diffused in time, which will cause the exchanged enzyme solution to re-enter the conical filter screen 28 through the filter plate 23, affecting the reaction effect inside it. In order to solve this problem, refer to Figure 1-Figure 6The swing device 5 includes a motor 51 fixedly mounted on the top cover 8, a No. 2 limit groove 52 is provided on the box cover 1, a reciprocating screw rod 53 is fixedly mounted on the output end of the motor 51, and two symmetrical groups of fixed rods 54 are fixedly mounted in the No. 2 limit groove 52, so that the movement of the limit block 55 is more stable, and a limit block 55 threadedly connected with the reciprocating screw rod 53 is slidably mounted on the fixed rod 54. The starting motor 51 drives the reciprocating screw rod 53 to rotate in the limit block 55 so that the limit block 55 moves in the No. 2 limit groove 52. Under the action of the connecting device 6, the limit block 55 drives the box cover 1 to move, and the box cover 1 drives the filter plate 23 to move, so that the position of the filter plate 23 is constantly changing, and drives the Schisandra chinensis inside the conical filter 28 to move, so that the reaction is more sufficient, while preventing the exchanged enzyme solution from flowing back, the reaction rate is accelerated.

[0038] Embodiment 4

[0039] Since there will be residual liquid in the equipment after the extraction of Schisandra chinensis lignans is completed, it is necessary to clean it several times in time before the next extraction. If the reaction enzyme in the equipment housing 7 is not cleaned up, it will have a serious impact on the next extraction. In order to solve this problem, refer to Figure 1-Figure 6 , a connecting device 6 is installed on the box cover 1, and the connecting device 6 includes two groups of No. 2 support rods 61 fixedly installed on the box cover 1, a connecting plate 62 is fixedly installed on the No. 2 support rod 61, and two groups of symmetrical plug blocks 63 are fixedly installed on the connecting plate 62. Two groups of plug holes 64 used in conjunction with the plug blocks 63 are opened on the limit block 55, and four groups of symmetrical L-shaped connecting blocks 71 are rotatably installed on the equipment housing 7. A box body 72 is inserted in the equipment housing 7, and sealing rings are installed in the box body 72 and on the outer wall of the box cover 1, so that the box body 72 and the box cover 1 can be sealed and connected, and it is convenient to adjust the position of the box cover 1 so that the plug blocks 63 and the plug holes 64 can be connected. Four groups of slots 73 used in conjunction with the L-shaped connecting blocks 71 are symmetrically opened on the box body 72, and an annular groove 81 is opened on the top cover 8, and an annular connecting shell 82 is slidably installed in the annular groove 81. Four symmetrical groups of positioning grooves 83 are provided, and a limiting ring 84 threadedly connected to the annular connecting shell 82 is fixedly installed on the equipment housing 7. Four groups of positioning blocks 85 used in conjunction with the positioning grooves 83 are symmetrically installed on the limiting ring 84. The box body 72 is placed in the equipment housing 7, and the four L-shaped connecting blocks 71 are rotated to limit the box body 72. Then the box cover 1 is connected to the box body 72, and the positioning grooves 83 on the top cover 8 are aligned with the positioning blocks 85 and inserted so that the plug 63 enters the jack 64. The limiting blocks 55 and the connecting plate 62 are connected, and the annular connecting shell 82 is rotated so that the top cover 8 is limited on the equipment housing 7, so as to extract the schisandra chinensis lignans. After the extraction is completed, the box body 72 and the box cover 1 can be taken out. Since the box body 72, the box cover 1 and the internal structure thereof are all disposable materials, the residual reaction enzyme is avoided from affecting the next extraction.
