Description

Technical Field

[0001] This utility model relates to the technical field of herbal plant extraction equipment, and in particular to a separation device for functional herbal plant extracts. Background Technology

[0002] Herbs refer to plants with soft stems, little lignified tissue, and whose above-ground parts mostly wither after the growing season. Functional herbal extracts are mixtures of physiologically active components extracted from their roots, stems, and leaves using processes such as water extraction and alcohol extraction; they represent a concentrated form of utilizing the efficacy of herbs. Separation devices separate and purify mixtures based on differences in the physical or chemical properties of substances, extracting target components or removing harmful components, making them key equipment for precise substance separation. Because herbal extract raw materials contain ineffective, harmful, or interfering substances in addition to the target active ingredients, this can reduce purity and affect safety. Separation devices can precisely remove impurities and enrich active ingredients, improving the stability, safety, and application value of the extract; they are crucial equipment from raw materials to qualified products.

[0003] The current separation devices have two prominent problems: First, the mixing uniformity of the raw materials before entering the separation stage is insufficient, and different components fail to fully integrate, directly leading to the incomplete separation of components in the subsequent separation process, affecting the purity and yield of the final product; second, the filter screen used for filtration is easily clogged by impurities in the raw materials during operation, which not only significantly reduces the separation efficiency and causes equipment malfunction, but also increases the difficulty of cleaning due to the tight adhesion of the clogging material. Frequent shutdowns for cleaning not only consume manpower and resources, but also further affect the overall production progress, causing a significant obstacle to continuous production. Therefore, a separation device for functional herbal plant extracts is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a separation device for functional herbal plant extracts, aiming to improve the problems of uneven mixing of raw materials leading to insufficient separation, easy clogging of the filter screen and difficulty in cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a separation device for functional herbal plant extracts, comprising a separation cylinder, a protective cover fixedly connected to the top of the separation cylinder, a motor fixedly connected inside the protective cover, a pulley fixedly connected to the output end of the motor, a fixed base fixedly connected to the top of the separation cylinder, a pulley rotatably connected to the bottom of the fixed base, a belt provided between the pulley rotatably and the pulley rotatably, a sieve barrel fixedly connected to the bottom of the pulley rotatably, a stirring assembly provided at the top of the separation cylinder, and a cleaning assembly provided at the bottom of the pulley rotatably. The stirring assembly includes a second protective cover, a second motor fixedly connected inside the second protective cover, a sun gear fixedly connected to the output end of the second motor, a mounting base fixedly connected to the bottom of the second protective cover, a gear ring rotatably connected inside the mounting base, a stirring rod rotatably connected to the outside of the mounting base, and a planetary gear fixedly connected to the top of the stirring rod.

[0006] As a further description of the above technical solution: The cleaning assembly includes multiple connecting plates, with a limit rod fixedly connected to the top of each connecting plate. A sliding groove is provided inside the fixing seat, and multiple cleaning brushes are fixedly connected to the outside of the connecting plates.

[0007] As a further description of the above technical solution: The planetary gear meshes with the ring gear, and the planetary gear meshes with the sun gear.

[0008] As a further description of the above technical solution: The top of the fixed base is fixedly connected to the feed hopper, the bottom of the first screen barrel is rotatably connected to the discharge port one, and the bottom of the second screen barrel is rotatably connected to the discharge port two.

[0009] As a further description of the above technical solution: A second liquid outlet pipe is fixedly connected to the outside of the separation cylinder, and a first liquid outlet pipe is fixedly connected to the outside of the first discharge port.

[0010] As a further description of the above technical solution: The mounting base is fixedly connected to the top of the separation cylinder, the stirring rod is rotatably connected to the outside of the second sieve barrel, and the first pulley is rotatably connected to the inside of the separation cylinder.

[0011] As a further description of the above technical solution: The limiting rod is slidably connected inside the slide groove.

[0012] As a further description of the above technical solution: The connecting plate is slidably connected to the outside of the second pulley, and the cleaning brush is rotatably connected to the outside of the first sieve barrel.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when separating the extract, the controller starts motor one, which drives pulley one to rotate. Through the belt drive pulley two, it drives sieve barrel one and sieve barrel two to rotate synchronously, generating centrifugal force to achieve extract separation. The discharge port two, discharge port one, liquid outlet one, and liquid outlet two work together to complete the graded collection of the separated liquid and solid products. At the same time, the controller starts motor two, which drives the sun gear to rotate, causing the planetary gear to rotate on its own axis and revolve around the sun, driving the stirring rod to stir the extract, improving separation efficiency, and achieving full stirring of the extract, thus improving separation efficiency.

[0014] 2. In this utility model, during the operation of the device, the sieve holes of sieve barrel one and sieve barrel two are easily clogged due to extract residue. The stirring rod is rotatably connected to the outside of sieve barrel two. When the planetary gear revolves and rotates, it continuously contacts and rotates relative to the surface of sieve barrel two, which can scrape off the impurities on its outside and clean the sieve holes in real time, avoiding clogging and affecting the efficiency of primary screening. At the same time, the rotation of pulley two drives the connecting plate to rotate, and the limiting rod slides up and down along the slide groove of the fixed seat, so that the connecting plate and the outer cleaning brush perform a compound motion of rotation and sliding. The cleaning brush is in close contact with the inner wall of sieve barrel one, which thoroughly removes the extract residue on its inner sieve holes, ensuring that the sieve holes of secondary screening are transparent and maintaining the separation efficiency. This realizes real-time cleaning of the sieve holes of the sieve barrel, avoids clogging, and maintains the separation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Reference Figures 1-7This utility model provides an embodiment of a separation device for functional herbal plant extracts, comprising a separation cylinder 1, a protective cover 3 fixedly connected to the top of the separation cylinder 1, a motor 4 fixedly connected inside the protective cover 3, a pulley 5 fixedly connected to the output end of the motor 4, a fixed base 8 fixedly connected to the top of the separation cylinder 1, a second pulley 6 rotatably connected to the bottom of the fixed base 8, a belt 7 disposed between the second pulley 6 and the first pulley 5, a sieve 9 fixedly connected to the bottom of the second pulley 6, a sieve 10 fixedly connected to the bottom of the second pulley 6, and a stirring assembly disposed at the top of the separation cylinder 1. The bottom of wheel 6 is equipped with a cleaning component. Separation cylinder 1, as the main load-bearing structure of the device, provides a closed space for the entire separation process, ensuring the stable operation of components such as centrifugal separation, stirring, and cleaning, while preventing extract leakage. Protective cover 3 serves a protective function, preventing external dust, liquid, or impurities from entering motor 4, reducing wear and extending its service life. Motor 4, as the core power source, is a key power component for extract separation. Pulley 5 connects motor 4 and belt 7, transmitting motor power to pulley 6. Fixing seat 8 provides support and fixation, ensuring the stability of pulley 6. 6. Stable rotation; the internal groove 22 provides a trajectory for the up-and-down movement of the cleaning components, which is the key foundation for the cleaning function. Pulley 2 6 receives power from pulley 1 5 via belt 7, driving the bottom sieve barrel 1 9 and sieve barrel 2 10 to rotate synchronously, simultaneously driving the cleaning components to operate, realizing the distribution and transmission of power, ensuring the coordinated work of multiple components. Pulley 1 5 transmits the motor power to pulley 2 6, and the power transmission is realized through belt 7. Sieve barrel 1 9 is fitted outside sieve barrel 2 10, with finer sieve holes, further filtering the extract initially separated by sieve barrel 1 9, separating out even finer particles. The particles are separated in two stages, improving the separation accuracy. The sieve barrel 10 rotates with the pulley 6 to generate centrifugal force, which performs preliminary separation of the extract through its own sieve holes, screening out larger particle impurities and achieving the first step of graded separation. The stirring component forms a compound motion of revolution and rotation, which in turn drives the stirring rod 21 to rotate in a complex trajectory, expanding the stirring range and preventing the herbal extract from accumulating or settling locally in the sieve barrel. The cleaning component makes the connecting plate 23 reciprocate up and down while rotating, which in turn drives the cleaning brush 25 to rotate up and down on the inner wall of the sieve barrel 9, thereby achieving a cleaning effect. The stirring assembly includes a second protective cover 15, inside which a second motor 16 is fixedly connected. A sun gear 20 is fixedly connected to the output end of the second motor 16. A mounting base 17 is fixedly connected to the bottom of the second protective cover 15. A gear ring 18 is rotatably connected inside the mounting base 17. A stirring rod 21 is rotatably connected to the outside of the mounting base 17. A planetary gear 19 is fixedly connected to the top of the stirring rod 21. The second protective cover 15 serves a protective function, preventing external impurities from entering the second motor 16 and protecting the motor from corrosion or contamination by extracts. The second motor 16 provides power to the stirring assembly, and the sun gear 20 distributes the power to the stirring assembly. At its core, the mounting base 17 provides a stable mounting foundation for the stirring assembly. The gear ring 18 expands the movement trajectory of the planetary gear 19, causing the planetary gear 19 to rotate on its own axis while revolving around the sun gear 20. The stirring rod 21, driven by the planetary gear 19, stirs the extract in the sieve barrel, ensuring uniform material distribution and preventing uneven separation due to sedimentation. Simultaneously, its rotation cleans the outer sieve holes of the sieve barrel 10, preventing clogging. The planetary gear 19 transmits the power of the motor 16 to the stirring rod 21, and through its own revolution and rotation, drives the stirring rod 21 to achieve complex trajectory stirring, preventing local accumulation of materials.

[0019] The cleaning assembly includes multiple connecting plates 23. A limiting rod 24 is fixedly connected to the top of the connecting plate 23. A sliding groove 22 is provided inside the fixing base 8. Multiple cleaning brushes 25 are fixedly connected to the outside of the connecting plate 23. The connecting plate 23 serves as the connecting structure of the cleaning assembly, transmitting the movement of the limiting rod 24 to the cleaning brushes 25, realizing the synchronous rotation and up-and-down sliding of the cleaning brushes 25 and the sieve barrel 9, ensuring cleaning linkage. The limiting rod 24 is restricted by the trajectory of the sliding groove 22, converting the fixed trajectory of the fixing base 8 into the up-and-down movement of the connecting plate 23, providing the power for the up-and-down movement of the cleaning brushes 25, ensuring that the cleaning range covers the entire height of the sieve barrel 9. The sliding groove 22 provides a sliding trajectory for the limiting rod 24, guiding the cleaning assembly to move up and down while rotating, so that the cleaning brushes 25 can thoroughly clean the inner sieve holes of the sieve barrel 9, avoiding incomplete cleaning of certain areas. The cleaning brushes 25 contact the inner side of the sieve barrel 9, rotate with the connecting plate 23 and slide up and down, cleaning the sieve holes of the sieve barrel 9 in real time, preventing extract residue from clogging.

[0020] Planetary gear 19 meshes with ring gear 18, and planetary gear 19 meshes with sun gear 20, forming a transmission structure of sun gear 20-planetary gear 19-ring gear 18. Sun gear 20 is driven to rotate by motor 16, which in turn drives planetary gear 19 to rotate. Planetary gear 19 also meshes with the fixed ring gear 18 and is forced to revolve around sun gear 20, thereby driving stirring rod 21 to perform a compound motion of revolution and rotation, which can fully disperse herbal plant extracts and prevent material agglomeration.

[0021] The top of the fixed base 8 is fixedly connected to the feed hopper 2, the bottom of the first screen barrel 9 is rotatably connected to the discharge port 11, and the bottom of the second screen barrel 10 is rotatably connected to the discharge port 22. The feed hopper 2 can directionally convey materials into the second screen barrel 10 to ensure feeding stability. The discharge port 11 collects the products that do not pass through the secondary screening screen barrel 9 through the gap between the discharge port 22 and the discharge port 22. The discharge port 22 is specifically for collecting the extract that does not pass through the aperture of the second screen barrel 10.

[0022] A liquid outlet pipe 2 13 is fixedly connected to the outside of the separator 1, and a liquid outlet pipe 14 is fixedly connected to the outside of the discharge port 11. The liquid outlet pipe 2 13 collects the liquid that has been screened by the two-stage sieve of the sieve barrel 9, and the liquid outlet pipe 14 collects the liquid that has been screened by the sieve barrel 2 10.

[0023] Mounting base 17 is fixedly connected to the top of separation cylinder 1, stirring rod 21 is rotatably connected to the outside of sieve barrel 2 10, and pulley 5 is rotatably connected to the inside of separation cylinder 1. Mounting base 17 provides stable support for stirring components, ensuring efficient operation of the stirring structure. Stirring rod 21 can scrape off large-pore extracts adhering to the surface of sieve barrel 2 10, preventing them from clogging the sieve holes of sieve barrel 2 10 and ensuring the screening efficiency of sieve barrel 2 10. Pulley 5 stably transmits power inside separation cylinder 1, driving sieve barrel 2 10 and sieve barrel 1 9 to rotate synchronously, providing continuous centrifugal force for the discharge port 2 12 to collect large-pore extracts and for sieve barrel 1 9 to perform secondary screening.

[0024] The limiting rod 24 is slidably connected inside the slide groove 22, so that the connecting plate 23 drives the cleaning brush 25 to move up and down while rotating.

[0025] The connecting plate 23 is slidably connected to the outside of the second pulley 6, and the cleaning brush 25 is rotatably connected to the outside of the first screen barrel 9. The connecting plate 23 rotates synchronously with the second pulley 6 and slides up and down, causing the cleaning brush 25 to rotate against the inner wall of the first screen barrel 9.

[0026] Working principle: During the separation of the extract, motor 4 is started by the controller. Motor 4 drives pulley 5 to rotate, and pulley 5 drives pulley 6 to rotate via belt 7. Pulley 6 drives sieve barrels 9 and 10 to rotate synchronously, generating centrifugal force. The extract is separated by sieve barrels 9 and 10. Discharge port 12 is used to collect extract that has not passed through the sieve barrel 10 or has excessively large pores. Discharge port 11, through the gap between itself and discharge port 12, collects the product that has passed through the sieve barrel 10 after the first-stage sieving but has not passed through the second-stage sieving of sieve barrel 9. Liquid outlet pipe 14 is used to collect the extract that has passed through the sieve barrel 10 after the first-stage sieving. The liquid after primary sieving; the liquid outlet pipe 2 13 is used to collect the liquid after secondary sieving by the sieve barrel 1 9. These four components work together to complete the graded collection of the separated liquid and solid products. During the operation of the device, the controller starts the motor 2 16, which drives the sun gear 20 to rotate. The sun gear 20 drives the planetary gear 19 that meshes with it to rotate. The gear ring 18 meshes with the planetary gear 19, thereby limiting the range of motion of the planetary gear 19. The planetary gear 19 revolves around the sun gear 20 while rotating on its own axis. The planetary gear 19 drives the stirring rod 21 to move, thereby achieving full stirring of the extract and improving the separation efficiency.

[0027] As the device operates, the sieve holes of sieve barrel 1 (9) and sieve barrel 2 (10) are prone to gradual clogging due to extract residue. The stirring rod 21, rotatably connected to the outside of sieve barrel 2 (10), continuously contacts and rotates relative to the surface of sieve barrel 2 (10) as it revolves and rotates with the planetary gear 19. This scrapes away impurities adhering to the outside of sieve barrel 2 (10), cleaning the sieve holes in real time and preventing clogging that could affect the primary sieve efficiency. Simultaneously, the pulley 2 (6) rotates, causing the connecting plate 23 to rotate synchronously. The limiting rod 24 at the top of the connecting plate 23 is embedded in the sliding groove 22 inside the fixed base 8. Due to the trajectory limitation of the sliding groove 22, the limiting rod 24 slides up and down along the sliding groove 22 while rotating with the connecting plate 23. This causes the connecting plate 23 and the cleaning brush 25 on the outside to move up and down synchronously during rotation. The cleaning brush 25 is in close contact with the inner wall of sieve barrel 1 (9). Through this combined rotation and sliding motion, residual extract inside the sieve holes of sieve barrel 1 (9) can be thoroughly removed, ensuring the sieve holes of the secondary sieve are clear and maintaining separation efficiency.
