Description

Technical Field

[0001] This invention relates to the field of natural product extraction equipment technology, specifically to a berberine hydrochloride extraction device. Background Technology

[0002] Natural product extraction equipment is a specialized system of equipment designed to separate and extract effective components with specific physiological activities, pharmacological effects, or practical value from various natural sources (including plant roots, stems, leaves, flowers, fruits, and seeds; animal tissues and secretions; and microbial fermentation products) using a series of scientific and technological methods. Its core objective is to precisely separate effective substances (such as alkaloids with antibacterial effects, antioxidant flavonoids, aroma-enhancing volatile oils, immunomodulatory polysaccharides, and surface-active saponins) originally encapsulated in complex natural matrices, while preserving the activity and purity of the target components to the maximum extent. This provides high-quality raw materials or intermediates for numerous fields such as pharmaceutical research and development, functional food processing, high-end cosmetics manufacturing, and health product development.

[0003] Chinese patent application number CN114230566A discloses an "optimized extraction process for berberine hydrochloride from Phellodendron amurense slices." This optimized extraction process includes the following steps: Phellodendron amurense slices are taken, air-dried naturally, and the pulverized powder is sieved. Dilute sulfuric acid is mixed with β-glucanase and cellulase in water and set aside. The Phellodendron amurense powder and sulfuric acid from step 1 are separately added to different extraction tanks and refluxed for extraction. All filtrates are combined, concentrated, and the pH is adjusted with dilute hydrochloric acid. After cooling, saturated NaCl solution is added, and the mixture is stored overnight at 4°C. The mixture is then filtered and dried to obtain the final product. This optimized extraction process for berberine hydrochloride from Phellodendron amurense slices improves enzyme activity through dilute sulfuric acid. The β-glucanase and cellulase thoroughly destroy the plant cell walls, resulting in more complete extraction of the active ingredients, thus achieving accelerated extraction, thorough extraction, and a high extraction rate.

[0004] Therefore, this invention patent also has the following technical defects:

[0005] 1. Low cooling efficiency and poor uniformity: In the existing technology, the material flow path of the cooling device is short and the structure is simple (such as straight pipe or simple coil). The contact area between the material and the cooling medium is limited, and the heat exchange is insufficient, resulting in excessively long cooling time. At the same time, the material lacks an effective diversion and mixing mechanism during the cooling process, and temperature gradients are easily formed due to local flow rate differences, resulting in local overcooling or overheating. This leads to uneven crystal size of berberine hydrochloride and affects the purity of the product.

[0006] 2. Insufficient controllability of the cooling process: Existing cooling devices mostly adopt a cooling medium supply method with fixed flow rate and direction, lacking a dynamic adjustment structure, and cannot adjust the cooling intensity in real time according to changes in material quantity and temperature; moreover, the cooling medium is prone to forming dead flow zones in the device, and the local cooling water has poor flow, which further reduces the stability of the cooling effect and makes it difficult to adapt to the cooling requirements of different extraction stages.

[0007] 3. Unreasonable structural design and high maintenance costs: In the existing technology, the internal pipelines (such as coils and tanks) of the cooling device are mostly fixed and closed structures, and lack anti-residue design. Materials are easy to accumulate in corners, inner walls and other parts, forming impurities after long-term use. At the same time, the cleaning components (such as scrapers and filters) are poorly compatible with the pipelines, making it difficult to completely remove residual impurities. This leads to frequent equipment shutdowns for maintenance, increasing maintenance costs and downtime.

[0008] To address this, a device for extracting berberine hydrochloride is proposed. Summary of the Invention

[0012] The cooling mechanism also includes two guide pipes three fixedly connected to the bottom end of guide pipe one and the top end of guide pipe two. Each of the two guide pipes three has a conical flow divider plate fixedly connected to its close end. The conical flow divider plate has a conical flow divider groove inside.

Four hinge blocks are fixedly connected in a ring array on the side of the two annular plates that are close to each other. A connecting plate is rotatably connected inside the hinge block. A lever is fixedly connected between the two connecting plates. A groove is opened on the side of the lever near the middle of the annular plate.

[0015] Furthermore, the three spirals of the guide tube are in the shape of a frustum.

[0017] Furthermore, the diversion pipe is connected to the interior of the conical diversion groove, the conical groove plate is a frustum shape that is wider at the top and narrower at the bottom, and the size of the annular slide is adapted to the inner cavity size of the cylindrical groove plate.

[0018] Furthermore, the inclined plate on the side near the dividing groove is inclined to the inside of the conical groove plate, and the water receiver is internally connected to the guide pipe.

[0019] Furthermore, the driver is electrically connected to an external controller.

[0020] Furthermore, the second cooler is internally connected to the first guide pipe.

[0021] Furthermore, the top end of the water outlet pipe is used to connect with the condenser.

[0022] Furthermore, the two annular plates are respectively positioned at the top and bottom of the two conical diverter plates, and the dimensions of the annular plates are adapted to the dimensions of the conical diverter plates.

[0023] Furthermore, the lever is made of rubber and can deform within a certain range.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This device extends the flow time of the material in the cooling water by using a conical spiral guide tube, thereby increasing the heat exchange contact area. At the same time, the combined design of the diversion tube, the dividing groove and the inclined plate allows the material liquid to be dispersed and then re-aggregated, promoting the internal liquid movement of the material liquid, avoiding local temperature differences, significantly improving the cooling uniformity, and ensuring that the berberine hydrochloride crystal particles are uniform.

[0026] 2.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0040] Please see Figures 1 to 9 An embodiment of the present invention is provided: a berberine hydrochloride extraction device, including a support frame 101, a water receiver 102, a cooler 103 and an external controller. The water receiver 102 is fixedly connected to the top of the support frame 101, the cooler 103 is fixedly connected to the top of the water receiver 102, a cooling mechanism 2 is provided in the middle of the cooler 103, and an adjustment mechanism 3 is provided at the top of the cooler 103.

[0041] The cooling mechanism 2 includes a water inlet valve body port 201 fixedly connected to the bottom end of the cooler 103, a drain valve body port 202 fixedly connected to the top end of the cooler 103, a guide pipe 203 fixedly connected to the top end of the cooler 103, and a guide pipe 204 fixedly connected to the bottom end of the cooler 103.

[0042] The regulating mechanism 3 includes a second cooler 301 fixedly connected to the top of the first cooler 103, a water outlet pipe 310 fixedly connected to the side wall of the top of the second cooler 301, and a connecting rod 302 fixedly connected between the first guide pipe 203 and the second guide pipe 204. The second cooler 301 is internally connected to the first guide pipe 203, and the top of the water outlet pipe 310 is used to connect with the condenser.

[0043] Preferably, the cooling mechanism 2 further includes two guide pipes 205 fixedly connected to the bottom end of guide pipe 1 203 and the top end of guide pipe 204. The water receiver 102 is internally connected to guide pipe 204. Guide pipe 205 is located below the horizontal plane where drain valve body port 202 is located. Guide pipe 205 is spiraled in a frustum shape. The two guide pipes 205 are fixedly connected to a conical diverter plate 206 at their close ends. The conical diverter plate 206 has a conical diverter groove 207 inside. The two conical diverter plates 206 are arranged in a ring array and fixedly connected to a number of diverter pipes 208. The diverter pipes 208 and the conical diverter grooves 207 are connected to each other. The internal structure of section 7 is interconnected. A cylindrical groove plate 209 is symmetrically fixedly connected to the outer wall of the diversion pipe 208. An annular slide 210 is fixedly connected to the top of the inner cavity of the cylindrical groove plate 209. The size of the annular slide 210 is adapted to the inner cavity size of the cylindrical groove plate 209. A conical groove plate 211 is slidably connected inside the annular slide 210. The conical groove plate 211 is a frustum shape that is wider at the top and narrower at the bottom. Several dividing grooves 212 are arranged in a ring array on the outer wall of the bottom end of the conical groove plate 211. An inclined plate 213 is fixedly connected to the inner wall of each dividing groove 212. The inclined surface of the inclined plate 213 on the side near the dividing groove 212 is inclined to the inner side of the conical groove plate 211.

[0044] It should be noted that the frustum-shaped spiral guide tube 205 not only extends the material flow path, but its frustum structure also allows the material to gradually disperse during the flow process, making full contact with the cooling water at different temperature layers in the cooler 103. The bottom cooling water temperature is lower, while the top temperature is slightly higher due to heat exchange, forming a gradient heat exchange. Compared with traditional straight pipes or equal-diameter coils, the heat exchange efficiency is improved.

[0045] The sliding fit between the conical groove plate 211 and the annular slide table 210 creates a self-cleaning effect: when the material impacts the inclined plate 213, the conical groove plate 211 rotates with the impact force, and its conical surface design allows the residual material to automatically slide off under the action of gravity and centrifugal force, reducing the amount of residue.

[0046] The rubber-material paddle 308 can deform to fit the outer wall of the cylindrical groove plate 209, and the groove 309 can accommodate the cleaning brush for deep cleaning. With the help of cooling water for back rinsing, the cleaning efficiency is improved.

[0047] Preferably, the adjustment mechanism 3 further includes a driver 303 symmetrically slidably connected to the outer wall of the connecting rod 302. The driver 303 is electrically connected to an external controller. Annular plates 304 are fixedly connected to the outer wall of the driver 303. The two annular plates 304 are respectively connected to the top and bottom of the two conical diverter plates 206. The size of the annular plates 304 is adapted to the size of the conical diverter plates 206. A telescopic rod 305 is fixedly connected between the two annular plates 304 on the side away from the connecting rod 302. Four hinge blocks 306 are fixedly connected in a ring array on the side of the two annular plates 304 that are close to each other. A connecting plate 307 is rotatably connected inside the hinge block 306. A lever 308 is fixedly connected between the two connecting plates 307. The lever 308 is made of rubber and can deform within a certain range. A groove 309 is provided on the side of the lever 308 near the middle of the annular plate 304.

[0048] It should be noted that: the four hinge blocks 306 on one side of each annular plate 304 are arranged in a circular array (spaced at 90° intervals), forming a rotating pair with the connecting plate 307 (rotation angle range 0-60°). When the annular plate 304 moves up and down, the connecting plate 307 can rotate around the hinge block 306, causing the lever plate 308 to produce a pitch angle change, thereby adjusting the thrust direction on the cooling water - when moving upward, the lever plate 308 tilts inward to enhance the accumulation of cooling water in the central area; when moving downward, it tilts outward to expand the range of cooling water disturbance.

[0049] The rubber-material baffle 308 has good elastic deformation capability (deformation range ≤30%), which can adapt to the curvature of the inner wall of the cooler 103, avoiding the leakage of cooling water due to gaps caused by rigid contact. The groove 309 on the inner side of the baffle 308 is arc-shaped (the radius of curvature is adapted to the cylindrical groove plate 209), which can form a "flow-convergence" effect when pushing the cooling water: the groove 309 first gathers the dispersed cooling water, and then guides it through the arc-shaped inner wall to the cylindrical groove plate 209, thereby improving the contact efficiency between the cooling water and the material flow area.

[0050] The telescopic rod 305 between the two annular plates 304 adopts a telescopic structure (such as a hydraulic rod or a high-precision lead screw). Its core function is to keep the relative positions of the two annular plates 304 synchronized when they move up and down, so as to avoid the annular plates 304 tilting due to uneven force on one side, and to ensure that the pusher plate 308 pushes the cooling water in the same direction, thereby reducing the generation of local eddies.

[0051] The driver 303 is symmetrically slidably connected to the outer wall of the connecting rod 302. Under the command of the external controller, it can move precisely along the axial direction of the connecting rod 302 (the stroke range is adapted to the height of the cooler 103), thereby driving the annular plate 304 fixed to its outer wall to move synchronously. The two annular plates 304 correspond to the top and bottom of the conical diverter plate 206 respectively, and their size is adapted to the conical diverter plate 206, ensuring that the cooling water cavity of the material diversion area can be covered during movement, so as to realize the directional control of the key cooling area.

[0052] The working principle of the above implementation is as follows:

[0053] The operation steps are as follows:

[0054] First, the operator connects the water supply device and the collection device to the inlet valve body 201 and the outlet valve body 202, respectively. Cooling water is supplied to the interior of cooler 103 through the inlet valve body 201, and then discharged through the outlet valve body 202. When the material liquid enters the interior of cooler 201 through the outlet pipe 310, after processing, it enters the interior of the connected guide pipe 305 through guide pipe 1 203. The material liquid then enters the interior of the conical diverter plate 206 through guide pipe 305. During the flow of the material liquid inside guide pipe 305, the material liquid is transported by the swirling manner of guide pipe 305, thereby increasing the flow time of the material liquid inside the cooling water. The conical design of guide pipe 305 allows the material liquid to transfer heat with the cooling water in different areas during the flow of the material liquid inside guide pipe 305, thereby improving the cooling efficiency of the material liquid.

[0055] Subsequently, the liquid material enters the interior of the diversion pipe 208 through the conical diversion groove 207, and then sequentially enters the interior of the cylindrical groove plate 209. The liquid material impacts the inclined plate 213 set inside the dividing groove 212, causing the conical groove plate 211 to rotate inside the annular slide table 210 under the impact. This allows the liquid material to be diverted through the dividing groove 212, and the process of the liquid material being dispersed and then re-aggregated promotes the movement of the liquid material on the outside, thereby improving the uniformity of the liquid material cooling process. When the liquid material flows into the guide pipe 205, which is fixedly connected to the guide pipe 204, through the diversion pipe 208, the liquid material undergoes secondary cooling through the guide pipe 205. Finally, it is discharged into the interior of the water receiver 102 through the guide pipe 204. In addition, the cooling water is supplied through a bottom input and top discharge method, which can ensure the stability of the cooling water temperature inside the cooler 103.

[0056] The device extends the flow time of the material in the cooling water by using a conical spiral guide tube 205, thereby increasing the heat exchange contact area. At the same time, the combined design of the diversion tube, the dividing groove 212 and the inclined plate 213 allows the material liquid to be dispersed and then re-aggregated, promoting the internal liquid movement of the material liquid, avoiding local temperature differences, significantly improving the cooling uniformity, and ensuring that the berberine hydrochloride crystal particles are uniform.

[0057] During the flow of the liquid material through the distribution pipe 208 and the cylindrical groove plate 209, the external controller controls the driver 303 to slide on the outer wall of the connecting rod 302 towards the top of the connecting rod 302. This causes the driver 303 to drive the annular plate 304 to slide synchronously inside the cooler 103. The annular plate 304 then drives the telescopic rod 305 to extend. During the movement of the annular plate 304, the telescopic rod 305 maintains stability. Simultaneously, the annular plate 304 drives the hinge block 306 to move synchronously. The hinge block 306 then drives the connecting plate 307, which is hinged to it, to move synchronously. This causes the connecting plate 307 to stretch the lever plate 308. Under the pull of the connecting plate 307, the lever plate 308 causes the groove 309 to move closer to the cylindrical groove plate 209. As the groove 309 moves, it moves the cooling water around the inner wall of the cooler 103 closer to the cylindrical groove plate 209, thereby increasing the flow of the cooling water and improving its cooling effect.

[0058] The device moves the annular plate 304 via the driver 303 in the adjusting mechanism 3, and pushes the cooling water to flow into the cylindrical trough plate 209 through the connecting plate 307 and the rubber lever 308, increasing the fluidity of the cooling water. The cooperation of the telescopic rod 305 and the hinge block 306 can flexibly adjust the angle of the lever 308, realizing the dynamic adjustment of the cooling intensity, adapting to different material liquid volumes and cooling requirements, and improving the applicability of the device.

[0059] The device reduces the residue of material liquid in the cylindrical trough plate 209 through the sliding connection between the conical trough plate 211 and the annular slide table 210 and the inclined design of the inclined plate 213; the rubber material of the lever plate 308 is deformable and the groove structure of the groove 309 is easy to clean, reducing the risk of impurity accumulation, extending the continuous operation time of the equipment, and reducing the frequency and cost of maintenance.
