Description

Technical Field

[0001] This invention relates to the field of plant extract extraction technology, specifically to a plant extract extraction device and extraction method. Background Technology

[0002] Plant extracts are products made from plants as raw materials. They are obtained or concentrated through physical and chemical extraction and separation processes according to the needs of the final product. Generally, they do not change the original components of the plant. Chlorophyll is a green natural pigment that is mainly found in chloroplasts in plants and some plankton and other organisms.

[0003] In existing technologies, filters are typically used to solidify and separate plant extracts. However, during this process, when the liquid enters the chamber through the feed pipe, its flow direction is relatively unidirectional, causing the falling liquid to frequently come into contact with a fixed point on the filter screen. This not only prevents other parts of the filter screen from being fully utilized, but also makes the same point on the filter screen prone to clogging due to the continuous impact of the falling liquid, thus reducing the effectiveness of the filter screen. Summary of the Invention

[0004] To address the problem of frequent single-point contact and clogging of the filter screen caused by direct liquid flow in existing technologies, this invention provides a plant extract extraction device and extraction method.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a plant extract extraction device, including an outer box, an inner box fixedly connected in the outer box, a belt layer fixedly connected in the inner box, and a filter screen fixedly connected to the bottom end of the belt layer;

[0006] The bottom of the filter screen is fixedly connected to an installation ring, and multiple horizontal blocks and multiple vertical blocks are fixedly connected to the installation ring. The outer casing is provided with a dispersing mechanism for guiding the flow of the filter screen. The dispersing mechanism includes a motor, a large gear, and a support frame. A small gear is fixedly connected to the output end of the motor. A small connecting rod is fixedly connected to the top of the large gear. A rotating rod is rotatably connected to the top of the support frame. A large connecting rod is fixedly connected to the top of the rotating rod. A support rod is fixedly connected to the large connecting rod. A pressing rod is fixedly connected to the top of the support rod. A bearing is fixedly connected to the top of the support rod. A rubber flexible rod is fixedly connected to the inner ring of the bearing.

[0007] Specifically, the top of the outer box is open, the bottom of the inner box is open, a feed pipe is fixedly connected to the top of the inner box, a discharge pipe is fixedly connected to the bottom of the outer box, the feed pipe is connected to the inner box, the discharge pipe is connected to the outer box, and multiple support legs are fixedly connected to the outer wall of the outer box.

[0008] Specifically, the inner box and the outer box are in a connected state, both of which are annular in shape. The diameter of the inner box is smaller than that of the outer box. The inner box is located inside the outer box. The bottom of the outer box is conical. The inner wall of the outer box does not contact the outer wall of the inner box.

[0009] Specifically, there are four horizontal blocks and four vertical blocks. The vertical blocks are located at the middle of each horizontal block at the bottom of the mounting ring. The horizontal blocks are all planar triangular in shape, and the vertical blocks are all curved triangular in shape. One end of each horizontal block and vertical block is arc-shaped, and the top of the extrusion rod is spherical.

[0010] Specifically, the large gear is rotatably connected to the outer wall of the outer casing, the motor is fixedly installed on one side of the outer wall of the outer casing, the large gear is meshed with the small gear, and the support frame is fixedly connected to the inside of the outer casing.

[0011] Specifically, the large connecting rod is L-shaped, the small connecting rod is L-shaped, the top end of the side rod of the large connecting rod is fixedly connected to the bottom end of the top rod of the small connecting rod, the outer ring of the bearing is fixedly connected to the support rod, the inner ring of the bearing is not in contact with the support rod, the top end of the rubber flexible rod is fixedly connected to the bottom end of the filter screen, the rubber flexible rod is not in contact with the support rod, the bearing and the extrusion rod are symmetrically connected at the top of the support rod, and the top end of the extrusion rod is located between one of the horizontal blocks and one of the vertical blocks.

[0012] The present invention also provides a method for extracting a plant extract, comprising the following steps:

[0013] Step 1: Introduce the plant extract solution that needs to be separated into the inner chamber through the feed pipe;

[0014] Step 2: Start the motor. The motor will drive the large gear to rotate through the small gear. The rotation of the large gear will drive the small connecting rod and the large connecting rod to rotate. The rotation of the large connecting rod will drive the squeezing rod to rotate through the support rod. The rotation of the squeezing rod will cause the filter screen to move irregularly horizontally and upward through the vertical and horizontal blocks. At this time, the filter screen will filter the extract at different positions.

[0015] Step 3: The extract that has been separated from the solid by the filter will flow to the bottom of the outer box and finally be discharged through the discharge pipe at the bottom of the outer box.

[0016] The beneficial effects of this invention are:

[0017] The motor drives the dispersing mechanism, which causes the extrusion rod to push the filter screen through the vertical and horizontal blocks to produce irregular horizontal and upward composite motion. Combined with the adaptive deformation of the rubber soft rod and bearing, it breaks the limitation of traditional single-point liquid impact on the filter screen, realizes dynamic contact between the liquid and the filter screen throughout the entire area, and ensures that all areas of the filter screen participate in filtration. This improves the effective filtration area utilization rate and effectively prevents local overload and clogging of the filter screen.

[0018] The up-and-down undulations and lateral shifts of the filter screen form a "wave"-like filter surface. By utilizing the dynamic effect generated by the fluctuation of the filter screen position, impurities in the liquid will not pass through the filter screen along with the liquid due to the impact of the liquid on the filter screen, thereby improving the retention rate of impurities by the filter screen and significantly enhancing the filtration efficiency.

[0019] The liquid flow path changes continuously with the movement of the filter screen, creating a dynamic flushing effect on the impurities on the filter screen. This flushing action can effectively prevent impurities from accumulating in a single location, and is particularly effective for plant extracts with high viscosity. Compared with traditional static filtration, the risk of clogging is reduced. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-5 As shown, the present invention provides the following technical solution:

[0029] Example 1: The plant extract extraction device of the present invention includes an outer box 1, an inner box 2 fixedly connected to the outer box 1, a belt layer 3 fixedly connected to the inner box 2, a filter screen 4 fixedly connected to the bottom end of the belt layer 3, the top of the outer box 1 is open, the bottom of the inner box 2 is open, a feed pipe 9 is fixedly connected to the top of the inner box 2, and a discharge pipe 10 is fixedly connected to the bottom of the outer box 1. The feed pipe 9 is connected to the inner box 2, the discharge pipe 10 is connected to the outer box 1, and the inner box 2 is connected to the outer box 1. Both the inner box 2 and the outer box 1 are annular, the diameter of the inner box 2 is smaller than the diameter of the outer box 1, the inner box 2 is located inside the outer box 1, the bottom end of the outer box 1 is conical, the inner wall of the outer box 1 does not contact the outer wall of the inner box 2, and multiple support legs 11 are fixedly connected to the outer wall of the outer box 1.

[0030] In use, the plant extract is introduced into the inner box 2 through the feed pipe 9. At this time, the liquid will fall onto the surface of the filter screen 4 and flow through the filter screen 4 into the outer box 1. Fixed impurities will be blocked by the filter screen 4. Since the bottom of the outer box 1 is conical, the liquid flowing into the outer box 1 will flow into the discharge pipe 10 at the bottom of the outer box 1, and then the separated liquid will be discharged through the discharge pipe 10. The belt layer 3 provides positional support for the filter screen 4. The belt layer 3 is elastic, and the elasticity of the belt layer 3 allows the filter screen 4 to move irregularly. The support legs 11 provide support for the outer box 1.

[0031] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a mounting ring 5 is fixedly connected to the bottom of the filter screen 4, multiple horizontal blocks 6 are fixedly connected to the mounting ring 5, multiple vertical blocks 7 are fixedly connected to the mounting ring 5, and a dispersing mechanism 8 for guiding the filter screen 4 is provided on the outer box 1. The dispersing mechanism 8 includes a motor 81, a large gear 82 and a support frame 83. A small gear 84 is fixedly connected to the output end of the motor 81, a small connecting rod 85 is fixedly connected to the top of the large gear 82, a rotating rod 86 is rotatably connected to the top of the support frame 83, a large connecting rod 87 is fixedly connected to the top of the rotating rod 86, a support rod 88 is fixedly connected to the large connecting rod 87, a pressing rod 89 is fixedly connected to the top of the support rod 88, a bearing 801 is fixedly connected to the top of the support rod 88, and a rubber flexible rod 802 is fixedly connected to the inner ring of the bearing 801.

[0032] There are four horizontal blocks 6 and four vertical blocks 7. The vertical blocks 7 are located at the middle of each horizontal block 6 at the bottom of the mounting ring 5. The horizontal blocks 6 are all planar triangular, and the vertical blocks 7 are all curved triangular. One end of both horizontal blocks 6 and vertical blocks 7 is arc-shaped. The top of the extrusion rod 89 is spherical. The large gear 82 is rotatably connected to the outer wall of the outer box 1. The motor 81 is fixedly installed on one side of the outer wall of the outer box 1. The large gear 82 is meshed with the small gear 84. The support frame 83 is fixedly connected to the inside of the outer box 1. The large linkage rod 87 is specifically L-shaped. The small connecting rod 85 is L-shaped. The top of the side rod of the large connecting rod 87 is fixedly connected to the bottom of the top rod of the small connecting rod 85. The outer ring of the bearing 801 is fixedly connected to the support rod 88, and the inner ring of the bearing 801 does not contact the support rod 88. The top of the rubber flexible rod 802 is fixedly connected to the bottom of the filter screen 4, and the rubber flexible rod 802 does not contact the support rod 88. The bearing 801 and the extrusion rod 89 are symmetrically connected at the top of the support rod 88. The top of the extrusion rod 89 is located between one of the horizontal blocks 6 and one of the vertical blocks 7.

[0033] In use, the plant extract is introduced into the inner chamber 2 through the feed pipe 9. Simultaneously, the motor 81 is started. The slow rotation of the motor 81's output end drives the small gear 84 to rotate, which in turn drives the large gear 82 to rotate slowly. As the large gear 82 rotates, the small connecting rod 85 on it rotates along with it. This small connecting rod 85 then drives the large connecting rod 87 to rotate. The large connecting rod 87 then drives the rotating rod 86 to rotate in place under the support of the support frame 83. The side rod of the large connecting rod 87 rotates along the space between the inner wall of the outer chamber 1 and the outer wall of the inner chamber 2. The rotation of the large connecting rod 87 drives the support rod 88 to rotate, which in turn drives the extrusion rod 89 to rotate. Simultaneously, the rotation of the support rod 88 also drives the shaft... The outer ring of bearing 801 rotates, while the inner ring of bearing 801 and rubber flexible rod 802 do not rotate because the top of rubber flexible rod 802 is fixedly connected to the bottom of filter screen 4. When the extrusion rod 89 rotates along the outer ring of mounting ring 5, it first extrudes vertical block 7. The side wall of vertical block 7 is inclined, and the spherical part at the top of extrusion rod 89 extrudes the inclined side wall of vertical block 7. When vertical block 7 is compressed, it moves upward. The upward movement of vertical block 7 acts on the position connected to filter screen 4, causing the position of filter screen 4 corresponding to the compressed vertical block 7 to tilt upward. The tilting of filter screen 4 causes the corresponding position of belt layer 3 to undergo adaptive deformation, which also acts on rubber flexible rod 802, causing rubber flexible rod 802 to deform. The rubber flexible rod 802 also causes the inner ring of the bearing 801 to rotate adaptively. At this time, the filter screen 4 is no longer parallel and becomes tilted. The falling liquid will then flow through the tilted surface of the filter screen 4, so that the filter screen 4 is no longer limited to a single point of liquid drop. When the squeezing rod 89 rotates to another position of the initially squeezed vertical block 7, the filter screen 4 will return to its original position under the drive of the belt layer 3. At this time, the continuously rotating squeezing rod 89 will squeeze the inclined side wall of the horizontal block 6. The pressure on the horizontal block 6 will cause the filter screen 4 to move laterally. However, due to the connection between the filter screen 4 and the belt layer 3, the filter screen 4 will not move horizontally during the lateral movement, but one end will be tilted up during the lateral movement. At this time, the belt layer 3 will also move irregularly. The filter screen 4 undergoes adaptive deformation, causing the center point of the irregularly moving filter screen 4 to no longer correspond to the liquid's falling position. This alters the contact surface between the filter screen 4 and the liquid. Simultaneously, the irregular movement of the filter screen 4 causes the liquid to flow on its surface. When the squeezing rod 89 rotates to a different position than the initially squeezed horizontal block 6, it squeezes another vertical block 7. This process repeats, causing the filter screen 4 to move irregularly. This serves to guide the falling liquid and change the contact position between the liquid and the filter screen 4, maximizing the use of the filter screen 4 and preventing clogging at a single point. Furthermore, the up-and-down movement and lateral shift of the filter screen 4 create a "wave-like" filter surface, utilizing the dynamic effect generated by the fluctuation of the filter screen 4's position.This design prevents impurities in the liquid from passing through filter 4 along with the liquid due to the impact of the liquid, thus improving the retention rate of impurities and significantly enhancing filtration efficiency. Furthermore, the constantly changing liquid flow path along with the movement of filter 4 creates a dynamic flushing effect on the impurities on the filter 4. This flushing action effectively prevents impurities from accumulating in a single location, and is particularly effective for highly viscous plant extracts. Compared to traditional static filtration, the risk of clogging is reduced.

[0034] The present invention also provides an extraction method suitable for a plant extract extraction device, comprising the following steps:

[0035] Step 1: Introduce the plant extract solution that needs to be separated into the inner box 2 through the feed pipe 9;

[0036] Step 2: Start motor 81. Motor 81 will drive large gear 82 to rotate through small gear 84. The rotation of large gear 82 will drive small connecting rod 85 and large connecting rod 87 to rotate. The rotation of large connecting rod 87 will drive squeezing rod 89 to rotate through support rod 88. The rotation of squeezing rod 89 will cause filter screen 4 to move irregularly horizontally and upward through vertical block 7 and horizontal block 6. At this time, different positions of filter screen 4 will filter the extract.

[0037] Step 3: The extract that has been separated from the solid by the filter screen 4 will flow to the bottom of the outer box 1 and finally be discharged through the discharge pipe 10 at the bottom of the outer box 1.
