Description

Technical Field

[0001] This utility model belongs to the field of mulberry leaf processing technology, and in particular relates to a mulberry leaf extract mixing device. Background Technology

[0002] Mulberry leaf extract is a concentrated extract of active ingredients obtained from the leaves of the mulberry tree (Morus alba) through a specific process. It is widely used in the pharmaceutical, food, health product, and cosmetic industries. Its core value lies in its rich content of various bioactive natural compounds.

[0003] In traditional stirred tank designs, the mixing process of mulberry leaf extract is often limited to simple mechanical stirring. This stirring method typically involves rotation around a single axis, resulting in a relatively simple flow pattern of the material within the tank, failing to create complex turbulence or three-dimensional convection. Due to insufficient directionality of the stirring force, relatively static dead zones easily form at the edges and bottom of the tank, leading to uneven distribution of active ingredients in the mulberry leaf extract. This can result in localized areas of excessively high or low concentrations. This uneven mixing not only affects the consistency of the final product's quality but can also impact the stability of subsequent processing steps due to localized over-concentration or under-concentration.

[0004] Furthermore, the rigid connection between the stirring motor and the stirring rod makes speed regulation lack buffering, easily generating instantaneous high torque during startup or speed change, resulting in a sudden increase in the impact force of the stirring blades on the material. Many heat-sensitive and shear-sensitive active ingredients in mulberry leaf extract, such as flavonoids, polysaccharides, and alkaloids, may undergo molecular chain breakage, conformational changes, or degradation under high shear forces, thereby reducing their biological activity and pharmacological effects.

[0010] The blade surface of the main blade is configured to push the raw material to rotate axially around the rotating rod during rotation.

[0011] When the main blade rotates, the thrust transmitted by the raw material drives the sub-blades to rotate around the axis of the rotating rod three, and the sub-blades stir the raw material in the axial direction of the rotating rod three.

[0013] Furthermore, the rotation axis of the sub-blade is spatially perpendicular to the rotation axis of the main blade, the horizontal center of the main blade is located above the horizontal center of the sub-blade, and the sub-blade is arc-shaped.

[0014] Furthermore, the upper surface of the can lid has four circular holes arranged in a ring, and four rotating rods are provided. The bottom ends of the four rotating rods pass through the four circular holes and are rotatably connected. The top ends of the four rotating rods are respectively fixed with gears.

[0019] Furthermore, the outer wall of the mixing tank is provided with a plurality of mounting holes arranged in a ring, and pipes are inserted into and fixed into the plurality of mounting holes.

[0020] Furthermore, the front end of the pipe has a second pipe hole, into which a rotating pipe extends.

[0023] 1. This utility model utilizes a rotating pipe connected to a pipeline, a rotating rod three connected to the rotating pipe, and sub-blades fixed to the rotating rod three within a mixing tank. When mixing mulberry leaf extract, the main blade rotates, pushing the raw material towards the sub-blades, causing the sub-blades to rotate. The sub-blades can mix the raw material along the y-axis, while the main blade can mix it along the x-axis. This achieves both x-axis and y-axis mixing, resulting in a more uniform and effective mixture of raw materials. Furthermore, it improves the productivity of raw material production per unit time.

This utility model utilizes a rotary drive mechanism located on the top of the can lid, a rotating rod rotatably connected to the can lid, and a main blade fixed to the bottom of the rotating rod. The drive end of the rotary drive mechanism is connected to the rotating rod. When it is necessary to mix mulberry leaf extract, various raw materials are placed into the can, and the motor is started, causing gear two to rotate. At the same time, gear one, rotating rod one, and main blade can rotate, allowing the main blade to mix the mulberry leaf extract at a low speed. This achieves the effect of facilitating low-speed mixing of mulberry leaf extract and avoiding excessive speed that could cause shearing damage to the active ingredients.

[0040] Please see Figures 1 to 9 The present invention provides two embodiments:

[0041] Example 1: A mulberry leaf extract mixing device, comprising:

[0042] Mixing tank 2, with a mixing trough 7 inside;

[0043] The can lid 3 is detachably installed on the upper surface of the mixing tank 2 and includes: a rotary drive mechanism set on the top of the can lid 3, a rotating rod 9 rotatably connected to the can lid 3, and a main blade 8 fixed to the bottom end of the rotating rod 9. The drive end of the rotary drive mechanism is connected to the rotating rod 9. In this embodiment, the rotary drive mechanism can directly use a motor and be directly connected to the rotating rod 9 through a coupling to drive the main blade 8 to rotate.

[0044] Pipeline 18 is fixedly inserted through the outer wall of tank cover 3 and includes: a rotating pipe 24 rotatably connected to pipeline 18, a rotating rod 22 rotatably connected to rotating pipe 24, and a sub-blade 23 fixed to rotating rod 22 located in mixing tank 7;

[0045] Among them, the blade surface of the main blade 8 is configured to push the raw material to rotate axially around the rotating rod 9 during rotation;

[0046] When the main blade 8 rotates, the thrust transmitted by the raw material drives the sub-blade 23 to rotate around the axis of the rotating rod 22, and the sub-blade 23 stirs the raw material in the axial direction of the rotating rod 22.

[0047] The rotation axis of the sub-blade 23 is spatially perpendicular to the rotation axis of the main blade 8. The horizontal center of the main blade 8 is located above the horizontal center of the sub-blade 23, and the sub-blade 23 is arc-shaped.

[0048] The outer wall of the mixing tank 2 has multiple mounting holes 17 arranged in a ring, and pipes 18 are inserted into and fixed in the multiple mounting holes 17 respectively;

[0049] Multiple mounting holes 17 are evenly distributed on the outer wall of the mixing tank 2 for fixing the pipes 18. The mounting holes 17 are precision machined to ensure coaxiality. The pipes 18 are rigidly connected to the mixing tank 2 by flanges or welding, and their internal channels are connected to the mixing tank 7. The layout of multiple pipes 18 allows the stirring force field to cover the entire circumference of the tank, eliminating the dead zone of traditional single-axis stirring. The flange / welding fixation avoids the loosening of the pipes 18 due to vibration, ensuring long-term operational stability.

[0050] Pipe 18 has a second pipe hole 26 at its front end, into which a rotating pipe 24 extends. Sealing shafts 20 are installed at the front and rear ends of the outer wall of the rotating pipe 24, and the sealing shafts 20 are rotatably connected within the second pipe hole 26. Pipe 24 has a first pipe hole 25 at its front end, and the rear end of a rotating rod 32 passes through the first pipe hole 25. Sealing shaft 27 is installed on the outer wall of the rotating rod 32, and the sealing shaft 27 is rotatably connected within the first pipe hole 25.

[0051] The rotating pipe 24 passes through the front and rear ends of the pipe 18, and achieves a rotary seal through two sealing shafts 30 made of materials such as PTFE or fluororubber. The sealing shafts 30 adopt a lip-shaped structure with built-in spring preload to adaptively compensate for wear; the double-seal design can withstand the seepage pressure of mixed liquids and prevent leakage or contamination of the bearings.

[0052] The rotating rod 22 and the rotating tube 24 are sealed by a sealing shaft 27, and a secondary seal is achieved by means such as a mechanical seal or a labyrinth seal. The inner wall of the tube hole 25 is plated with hard chrome to reduce the coefficient of friction. The surface of the rotating rod 22 is polished to a mirror finish.

[0053] The main seal shaft 20 and the auxiliary seal shaft 1 27 together form a redundant sealing system.

[0054] The front end of the rotating rod 22 is provided with a threaded groove 28. The outer wall of the rotating tube 24 is fixed with a bracket 20. The upper surface of the bracket 20 is provided with a groove 21. The front end of the bracket 20 is provided with a threaded hole 32. The screw 31 extends into the threaded groove 28 and is threadedly connected. The screw 31 passes through the threaded hole 32 and is threadedly connected. The front end of the screw 31 is fixed with a turntable 19.

[0055] A screw 31 extends into the threaded groove 28 and is threadedly connected. The screw 31 passes through the threaded hole 32 and is threadedly connected. The screw 31 extends into the threaded groove 28 through the threaded hole 32 and is threadedly connected, so that the angle of the sub-blade 23 can be adjusted, and the sub-blade 23 after the angle is adjusted can be positioned.

[0056] The main blade 8 extends into the mixing tank 7 opened in the mixing tank 2. The main blade 8 and the sub-blade 23 are horizontally aligned, and the sub-blade 23 is arc-shaped.

[0057] When the blade 23 rotates, its curved surface guides the liquid to form a gradual flow, rather than the sudden impact of the right-angle blade, thereby reducing the mechanical shear damage to the active ingredients in the mulberry leaf extract; the arc structure can decompose fluid resistance, allowing some liquid to diffuse along the blade's curved surface to the edge of the tank, enhancing the radial mixing effect and avoiding the problem of traditional straight blades only producing unidirectional flow.

[0058] The arc design conforms to the natural flow trajectory of fluids and can reduce stirring resistance compared to right-angle blades; the arc wrap angle of the sub-blade 23 is 30°~60°. If it is too large, it will easily lead to turbulent flow field, and if it is too small, the mixing force will be insufficient.

[0059] The sub-blade 23 should be made of stainless steel 316L or titanium alloy to avoid deformation during high-speed rotation that could cause curvature distortion; spray PTFE or ceramic coating to further reduce the frictional resistance of the curved surface and prevent the adhesion of mulberry leaf polyphenols.

[0060] In this embodiment, when it is necessary to mix the mulberry leaf extract, the mulberry leaf extract is poured into the mixing tank 7, and other raw materials are added. The screw 31 is rotated, causing the rotating rod 22 and the sub-blade 23 to rotate. The sub-blade 23 is adjusted to a suitable angle. When the main blade 8 rotates, the raw materials rotate and push towards the sub-blade 23, causing the sub-blade 23 to rotate. When the sub-blade 23 rotates, its curved surface guides the liquid to form a gradual flow, rather than the sudden impact of right-angle blades, thereby reducing the mechanical shear damage to the active ingredients in the mulberry leaf extract, such as polysaccharides and flavonoids. The arc-shaped structure can decompose fluid resistance, allowing some liquid to diffuse along the curved surface of the blades to the edge of the tank, enhancing the radial mixing effect and avoiding the problem of traditional straight blades only producing unidirectional flow. This achieves the effect of allowing the mulberry leaf extract to be mixed in a relatively non-directional manner, resulting in a thorough and uniform mixing of the mulberry leaf extract.

[0061] Example 2:

[0062] The difference between this embodiment and Embodiment 1 is that:

[0063] The upper surface of the can lid 3 has four circular holes 15 arranged in a ring. There are four rotating rods 9. The bottom ends of the four rotating rods 9 pass through the four circular holes 15 respectively and are rotatably connected. The top ends of the four rotating rods 9 are respectively fixed with gears 11.

[0064] The can lid 3 has four rotating rods 9, each with a main blade 8 mounted at its bottom and linked to a gear 11 at its top. The motor 5 drives the central gear 14, causing all the main blades 8 to rotate synchronously. This allows multiple main blades 8 to stir from different positions, breaking the limitations of single-axis mixing and preventing localized accumulation or stratification. This is especially suitable for high-viscosity extracts and also achieves dispersed stirring, reducing mechanical damage to the active ingredients.

[0065] All four gears 11 mesh with gear 2 14. Gear 11 is fixed to the top of the rotating rod 9. Support 4 is fixed to the upper surface of the can lid 3. Rotating rod 2 13 is rotatably connected in the support 4. Gear 2 14 is fixed to the bottom of rotating rod 2 13. Gear 2 14 meshes with gear 11.

[0066] Main gear (Gear 2, 14): fewer teeth (e.g., 20-30 teeth), module must meet strength requirements; Driven gear (Gear 1, 11): number of teeth is an integer multiple of the main gear (e.g., 40-60 teeth), ensuring accurate transmission ratio and smooth meshing. This allows the main blades 8 to rotate at low speed, avoiding excessive speed that could cause shear damage to the active ingredients.

[0067] The rotary drive mechanism includes a bracket 4, a groove 12 at the front end of the bracket 4, a circular hole 16 on the upper surface of the bracket 4, a motor 5 fixed on the upper surface of the bracket 4, a drive shaft of the motor 5 extending into the circular hole 16, a rotating rod 13 fixed at the bottom end of the drive shaft of the motor 5, a gear 14 fixed at the bottom end of the rotating rod 13, and four gears 11 meshing with each other in a ring on the outer wall of the gear 14.

[0068] The motor 5 is fixed by the bracket 4 and drives the rotating rod 13 and the gear 14. The gear 14 meshes with the ring-shaped gear 11 to achieve power distribution. This ensures that all main blades 8 rotate at the same speed, the mixing effect is controllable, and the multiple gears 11 share the torque, extending the life of the motor 5. At the same time, the meshing design of gears 11 and 14 reduces operating vibration.

[0069] The bottom of the mixing tank 2 is provided with a second mounting hole 29, into which the feed pipe 6 extends and is fixed. The outer wall of the mixing tank 2 is fixed with three support pillars 1 in a ring.

[0070] A support column 1 is fixed to the lower end of the outer wall of the mixing tank 2 to support the entire device and maintain stability. The support columns 1 are arranged in a ring array to ensure uniform force distribution and prevent the mixing tank 2 from tilting or shaking due to vibration during mixing. The three-legged support structure distributes the weight and avoids deformation due to single-point pressure. The bottom of the mixing tank 2 is designed to be suspended for easy cleaning or maintenance of the discharge port. A mounting hole 29 is opened at the bottom of the mixing tank 2, and the discharge pipe 6 is fixed in it for discharging material after mixing. The discharge pipe 6 is connected to a valve to achieve controlled discharge. The discharge pipe 6 is located at the lowest point to reduce material residue. The fixed connection prevents leakage and is suitable for liquids or viscous extracts.

[0071] The upper surface of the mixing tank 2 is attached to the lower surface of the tank cover 3, and the upper surface of the mixing tank 2 and the tank cover 3 are detachably connected by bolts 10.

[0072] The lid 3 is fastened to the mixing tank 2 with bolts 10. A rubber ring is placed on the contact surface for a smooth and tight fit, ensuring a seal. The number of bolts 10 can be adjusted according to pressure requirements. This also prevents liquid splashing or volatile components from escaping during mixing, and allows for quick disassembly and thorough cleaning of the dead corners of the mixing tank 7.

[0073] In this embodiment, when it is necessary to mix the mulberry leaf extract, the mulberry leaf extract is poured into the mixing tank 7, and other raw materials are added. The mixing tank 2 is connected to the tank cover 3 by bolts 10. The motor 5 is started, which causes the rotating rod 13 and the gear 14 to rotate. At the same time, the gear 11, the rotating rod 9 and the main blade 8 are driven to rotate, so that the multiple main blades 8 can mix the mulberry leaf extract with other raw materials at a low speed, thereby avoiding the effect of shearing and destroying the active ingredients in the mulberry leaf extract due to excessive speed.

[0074] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
