An emulsification apparatus for making a multiphase microemulsion

Abstract

This utility model discloses an emulsification device for producing multiphase microemulsions, relating to the field of emulsification equipment technology. The device includes a base, with an emulsification tank and a water tank respectively mounted on the top of the base. A sealing cap is installed on the top of the emulsification tank, and a piston box is located on one side of the tank. A lead screw is mounted on the piston box via a fixing bracket. A threaded block is threaded to the outer surface of the lead screw, and a piston rod is fixed to the bottom of the threaded block. When cleaning the emulsification tank is required, the operator starts a first motor, which drives a worm gear to rotate. The meshing transmission between the worm gear and the worm wheel drives the rotating shaft to rotate, thereby causing the winding wheel to rotate to complete the rope unwinding operation. During this process, the counterweight ring uses its own weight to generate a downward pulling force, causing the scraper ring to perform a close-fitting scraping motion along the inner wall of the emulsification tank from top to bottom, quickly and effectively removing most of the residue on the tank wall. Moreover, the cleaning components do not come into contact with the materials during the emulsification process, reducing material residue.

Description

Technical Field

[0001] This utility model relates to the field of emulsification equipment technology, specifically to an emulsification device for producing multiphase microemulsions. Background Technology

[0002] In modern industrial production, multiphase microemulsion preparation technology is widely used in chemical, pharmaceutical, food, and materials fields. From cosmetic emulsion formulation to nanomaterial synthesis, from pharmaceutical emulsion preparation to food emulsion production, all rely on efficient and stable emulsification equipment to achieve uniform mixing of materials. With the increasing intelligence and automation of industrial production, in addition to meeting the core function of material emulsification, the cleaning efficiency and ease of maintenance of emulsification equipment have also become key concerns in the industry.

[0003] However, after the emulsification process is completed, stubborn residues often adhere to the inner walls and surfaces of the stirring mechanism of the emulsion due to the high viscosity and complex composition of the emulsion. Traditional manual cleaning methods are not only inefficient and time-consuming, but also have the problem of cleaning dead spots that are difficult to thoroughly remove. In addition, human operation may cause scratches on the inner walls of the equipment. Although some existing emulsification devices are equipped with cleaning mechanisms, such as the nano-emulsion dedicated emulsification kettle cleaning device with patent number CN212944481U, which achieves relatively convenient inner wall cleaning through mechanical structure cooperation and improves the drawbacks of manual cleaning to a certain extent, such devices still have significant limitations: First, the internal threaded rod is exposed to the emulsification environment, and the emulsion can easily seep into the thread groove to form residues, making subsequent cleaning extremely difficult; Second, the annular cleaning block wears out severely after long-term use, resulting in a significant decrease in the scraping cleaning effect, and it is difficult to replace it quickly; Third, the cleaning function is limited, only able to scrape the inner wall of the emulsification kettle, and cannot effectively rinse key components such as the stirring mechanism, so that residual emulsion may affect the quality of the next batch of products. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an emulsification device for producing multiphase microemulsions, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emulsification device for producing multiphase microemulsions, comprising a base, an emulsification tank and a water tank respectively disposed on the top of the base, a sealing cover installed on the top of the emulsification tank, a piston box disposed on one side of the emulsification tank, a lead screw mounted on the piston box via a fixing bracket, a threaded block threaded to the outer surface of the lead screw, a piston rod fixed to the bottom of the threaded block, and the bottom end of the piston rod extending into the interior of the piston box and fixed with a piston plate, a water suction pipe and a water delivery pipe connected to the bottom of the piston box, and an annular pipe fixed to the lower interior of the sealing cover. The bottom of the annular tube is provided with several sets of nozzles. The top two sides of the sealing cover are welded with mounting brackets, and the inner side of the mounting brackets is rotatably connected to a rotating shaft. A first motor is installed on the top of one set of mounting brackets, and the output end of the first motor is connected to a worm gear. The two ends of the rotating shaft are respectively installed with a worm wheel and a driving bevel gear. Both sides of the outer surface of the rotating shaft are fixed with winding wheels. The outer surface of the winding wheels is fixed with a connecting rope, and one end of the rope extends into the interior of the emulsifying tank and is fixed with a counterweight ring. The bottom of the counterweight ring is connected to a scraper ring by fastening bolts. The top of the scraper ring has several sets of water leakage holes.

[0006] Furthermore, a second motor is installed in the middle of the top of the sealing cover, and the output end of the second motor is connected to a stirring shaft. A stirring blade is fixed on the outer surface of the stirring shaft, and several sets of through holes are penetrated on the outer surface of the stirring blade.

[0007] By adopting the above technical solution, the second motor drives the stirring shaft to rotate the stirring blades during operation. The through hole allows the liquid to shear the material state during the stirring process, which not only enhances the uniformity of material mixing, but also reduces stirring resistance and improves stirring efficiency. The structure is simple and practical.

[0008] Furthermore, a control panel is installed on the top of the sealing cover, and both the second motor and the first motor are electrically connected to the control panel.

[0009] By adopting the above technical solution, staff can easily control the second motor and the first motor through the control panel, controlling their start-stop and speed.

[0010] Furthermore, a feeding port is provided on one side of the top of the sealing cap, and a discharge port runs through the middle of the bottom of the emulsifying tank.

[0011] By adopting the above technical solution, the feeding port facilitates precise material addition, and the discharge port enables rapid discharge of emulsion. The two work together to form a complete channel for material entry and exit.

[0012] Furthermore, a guide plate is provided at the bottom of the emulsification tank, and guide rods are fixed on both sides of the top of the guide plate. The counterweight ring is sleeved on the outer surface of the guide rod, and the counterweight ring slides in cooperation with the guide rod.

[0013] By adopting the above technical solution, the guide rod provides a precise track for the sliding of the counterweight ring, so that the scraper ring remains stable when it moves vertically along the inner wall of the emulsification tank, avoids deviation, and ensures that the scraping cleaning effect is uniform and reliable. The structural design optimizes the cleaning path and material discharge process.

[0014] Furthermore, the connecting rope is provided in two sets, and the connecting rope is made of steel wire rope material.

[0015] By adopting the above technical solution, the wire rope has high strength and good wear resistance, and can withstand the weight of the counterweight ring and scraper ring as well as the tension during the movement. The two sets of connecting ropes are symmetrically distributed to ensure that the counterweight ring is subjected to uniform force when it is vertically raised and lowered.

[0016] Furthermore, the worm gear meshes with the worm wheel, the driving bevel tooth meshes with the driven bevel tooth, and the outer surfaces of the worm gear, worm wheel, driving bevel tooth, driven bevel tooth, and lead screw are coated with lubricating oil.

[0017] By adopting the above technical solution, the meshing of the worm and worm wheel has self-locking properties, which facilitates the positioning of the counterweight ring and scraper ring. The lubricating oil can reduce frictional losses between various transmission components, reduce operating noise, avoid wear of parts caused by dry friction, prevent rusting, adapt to use in exposed environments, ensure the smooth and efficient operation of the transmission system, extend the service life of mechanical components, and improve the reliability and stability of equipment operation.

[0018] Furthermore, the scraper ring is made of wear-resistant rubber material, and the edge of the scraper ring is in contact with the inner wall of the emulsification tank.

[0019] By adopting the above technical solution, the wear-resistant rubber material has both elasticity and wear resistance. It can conform to the complex curved surface of the can wall through elastic deformation, and resist the wear caused by long-term scraping. The close contact between the edge and the can wall ensures that there are no dead corners when scraping, effectively removing the residue on the inner wall.

[0020] Furthermore, one end of the water supply pipe is connected to the annular pipe, the water supply pipe is made of rubber hose, and both the water supply pipe and the pumping pipe are equipped with one-way valves on their outer surfaces.

[0021] By adopting the above technical solution, the flexibility of the rubber hose can adapt to the disassembly of the sealing cap. The one-way valve ensures that the cleaning water can only enter the piston box from the water tank through the pumping pipe under the action of the piston plate, and then flow to the ring pipe through the water delivery pipe, preventing liquid backflow and ensuring the stability and reliability of the cleaning water circulation system. The structural design takes into account both flexibility and functionality.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model comprises a first motor, a worm gear, a worm wheel, a take-up reel, a rotating shaft, a connecting rope, a counterweight ring, and a scraper ring. When the emulsification tank needs cleaning, the operator starts the first motor, which drives the worm gear to rotate. The meshing transmission between the worm gear and the worm wheel drives the rotating shaft to rotate, which in turn causes the take-up reel to rotate and complete the rope unwinding operation. During this process, the counterweight ring uses its own weight to generate a downward pulling force, which drives the scraper ring to perform a close-fitting scraping motion along the inner wall of the emulsification tank from top to bottom, which can quickly and effectively remove most of the residue on the tank wall. Compared with traditional manual cleaning methods, this structure significantly improves cleaning efficiency, reduces manpower input, and the cleaning components do not come into contact with the materials during the emulsification process, reducing material residue.

[0024] 2. Based on the above configuration, this utility model also includes an active bevel gear, a driven bevel gear, a lead screw, a threaded block, a piston rod, a water tank, a water pumping pipe, a water supply pipe, an annular pipe, and a nozzle. When the first motor drives the rotating shaft to rotate, the meshing transmission of the active and driven bevel gears starts synchronously, driving the lead screw to rotate. Under the rotation of the lead screw, the threaded block precisely pushes the piston rod and piston plate downward within the piston box, efficiently transporting the cleaning water in the piston box to the annular pipe through the water supply pipe, and spraying it evenly in a fan shape or mist through the nozzle. The strong water flow cleans the internal parts and inner wall of the emulsification tank. It performs all-round rinsing, forming a dual cleaning mode of "water rinsing + scraping" with the mechanical scraping of the scraper ring, thoroughly cleaning residues and significantly improving cleaning efficiency and cleanliness; after the cleaning operation is completed, the first motor rotates in reverse, the rotating shaft drives the winding wheel to retract the connecting rope, so that the counterweight ring and scraper ring can be quickly reset. At the same time, the active bevel gear and the driven bevel gear drive in opposite directions, the screw drives the threaded block to move upward, the piston rod pulls the piston plate to reset, and the water pipe automatically draws clean water from the water tank into the piston box, so that it can be quickly put into use for the next cleaning. The structure is compact and reasonable, and the operation is stable and reliable.

[0025] 3. The scraper ring and counterweight ring of this utility model are designed with fastening bolts for easy disassembly. The fastening bolts are made of stainless steel, allowing workers to replace the scraper ring periodically. During replacement, workers can remove the sealing cover, allowing the counterweight ring to slide off the guide rod (the top of the guide rod is not fixed to the sealing cover), and then use the fastening bolts to disassemble the scraper ring. This design facilitates the replacement and maintenance of the worn scraper ring, ensuring the cleaning effect. The top of the scraper ring has several sets of drainage holes. During rinsing, some cleaning water and residue will remain on the top of the scraper ring, and the drainage holes allow the cleaning water and residue to drain away, further improving the cleaning effect.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1: An emulsification device for producing multiphase microemulsions, such as... Figures 1-5As shown, the system includes a base 1, with an emulsifying tank 2 and a water tank 3 respectively mounted on the top of the base 1. A sealing cover 4 is installed on the top of the emulsifying tank 2, and a feeding port 12 is located on one side of the top of the sealing cover 4. A discharge port 28 runs through the center of the bottom of the emulsifying tank 2. The feeding port 12 facilitates precise material addition, and the discharge port 28 allows for rapid discharge of the emulsion. Together, they form a complete channel for material entry and exit. A piston box 14 is located on one side of the emulsifying tank 2. A lead screw 16 is mounted on the piston box 14 via a fixing bracket 15. A threaded block 17 is threaded onto the outer surface of the lead screw 16, and a piston rod 20 is fixed to the bottom of the threaded block 17. The bottom end of the piston rod 20 extends into the piston box 14 and is fixed with a piston plate 29. A water suction pipe 21 and a water delivery pipe 22 are connected to the bottom of the piston box 14. An annular pipe 23 is fixed to the lower part of the interior of the sealing cover 4, and several sets of nozzles 24 are located at the bottom of the annular pipe 23. Both sides of the top of the sealing cover 4 are welded... A mounting bracket 5 is attached, and a rotating shaft 8 is rotatably connected to the inner side of the mounting bracket 5. A first motor 6 is mounted on the top of the mounting bracket 5, and a worm gear 7 is connected to the output end of the first motor 6. A worm wheel 9 and a driving bevel gear 18 are respectively mounted on both ends of the rotating shaft 8. A winding wheel 10 is fixed on both sides of the outer surface of the rotating shaft 8. A connecting rope 30 is fixed on the outer surface of the winding wheel 10, and one end of the rope extends into the interior of the emulsifying tank 2 and is fixed with a counterweight ring 32. A scraper ring 33 is connected to the bottom of the counterweight ring 32 by a fastening bolt 35. Several sets of drainage holes 34 are penetrating the top of the scraper ring 33. The scraper ring 33 is made of wear-resistant rubber material, and the edge of the scraper ring 33 contacts the inner wall of the emulsifying tank 2. The wear-resistant rubber material has both elasticity and wear resistance. It can conform to the complex curved surface of the tank wall through elastic deformation and resist the wear caused by long-term scraping. The close contact between the edge and the tank wall ensures that there are no dead corners during scraping and effectively removes the residue on the inner wall.

[0035] See Figures 1-2 In the above embodiment, a second motor 11 is installed in the middle of the top of the sealing cover 4. The output end of the second motor 11 is connected to a stirring shaft 31. A stirring blade 25 is fixed on the outer surface of the stirring shaft 31, and several sets of through holes are passed through the outer surface of the stirring blade 25. When working, the second motor 11 drives the stirring shaft 31 to rotate the stirring blade 25. The through holes allow the liquid to shear the material state during the stirring process, which not only enhances the uniformity of material mixing, but also reduces stirring resistance and improves stirring efficiency. The structure is simple and practical.

[0036] See Figure 1 In the above embodiment, a control panel 13 is installed on the top of the sealing cover 4, and the second motor 11 and the first motor 6 are both electrically connected to the control panel 13. The operator can easily control the second motor 11 and the first motor 6 through the control panel 13 to control the start, stop and speed.

[0037] See Figures 1-3 In the above embodiment, the connecting rope 30 is provided in two sets, and the connecting rope 30 is made of steel wire rope material. The steel wire rope has high strength and good wear resistance, and can withstand the gravity of the counterweight ring 32 and the scraper ring 33 as well as the tension during the movement. The two sets of connecting ropes 30 are symmetrically distributed to ensure that the counterweight ring 32 is subjected to uniform force when it is vertically raised and lowered.

[0038] See Figures 1-3 In the above embodiments, the worm 7 meshes with the worm wheel 9, and the driving bevel tooth 18 meshes with the driven bevel tooth 19. The outer surfaces of the worm 7, worm wheel 9, driving bevel tooth 18, driven bevel tooth 19, and lead screw 16 are coated with lubricating oil. The meshing of the worm 7 and worm wheel 9 has self-locking properties, which facilitates the positioning of the counterweight ring 32 and scraper ring 33. The lubricating oil can reduce frictional losses between various transmission components, reduce operating noise, avoid wear of parts caused by dry friction, prevent rusting, and adapt to use in exposed environments. This ensures the smooth and efficient operation of the transmission system, extends the service life of mechanical components, and improves the reliability and stability of equipment operation.

[0039] See Figures 1-3 In the above embodiment, one end of the water supply pipe 22 is connected to the annular pipe 23. The water supply pipe 22 is made of rubber hose, and both the outer surfaces of the water supply pipe 22 and the water suction pipe 21 are equipped with one-way valves. The flexibility of the rubber hose can adapt to the disassembly of the sealing cover 4. The one-way valve ensures that the cleaning water can only enter the piston box 14 from the water tank 3 through the water suction pipe 21 under the action of the piston plate 29, and then flow to the annular pipe 23 through the water supply pipe 22, preventing liquid backflow and ensuring the stability and reliability of the cleaning water circulation system. The structural design takes into account both flexibility and functionality.

[0040] Example 2: To make the counterweight ring displacement more stable and to facilitate the flow of the emulsion, resulting in more thorough and rapid emulsion discharge, Example 2 is an improvement on Example 1. (See attached document for details.) Figures 2-5 The emulsifying tank 2 has a guide plate 26 located at the bottom inside, and guide rods 27 are fixed on both sides of the top of the guide plate 26 (the top of the guide rods 27 are not fixed to the sealing cover 4; this design is to facilitate the removal of the sealing cover 4). The counterweight ring 32 is sleeved on the outer surface of the guide rod 27, and the counterweight ring 32 slides in cooperation with the guide rod 27. The guide rod 27 provides a precise track for the counterweight ring 32 to slide, so that the scraper ring 33 remains stable when it moves vertically along the inner wall of the emulsifying tank 2, avoiding deviation and ensuring that the scraping cleaning effect is uniform and reliable. The structural design optimizes the cleaning path and material discharge process.

[0041] The implementation principle of this utility model is as follows: During operation, the operator first adds oil phase, water phase, and surfactants into the emulsification tank 2 through the feeding port 12, and then closes the feeding port 12 after the addition is completed. Then, the operator starts the second motor 11 through the control panel 13. The second motor 11 drives the stirring shaft 31 and stirring blades 25 to rotate. The through holes on the stirring blades 25 promote convection circulation of the liquid, quickly and evenly mixing the various materials to complete the emulsification. After the emulsification operation is completed, the operator first opens the discharge port 28 in the middle of the bottom of the emulsification tank 2. Under the guidance of the guide plate 26, the emulsion is quickly and thoroughly discharged from the discharge port 28. After discharge, the operator operates the control panel 13 to start the first motor 6. The first motor 6 drives the worm gear 7 to rotate, which in turn drives the worm wheel 9 to rotate the rotating shaft 8. This causes the winding wheel 10 to rotate and release the rope. The counterweight ring 32 slides down the guide rod 27 under gravity, driving the scraper ring 33 to scrape the inner wall of the emulsification tank 2. At the same time, the active bevel gear 18 on the rotating shaft 8 drives... Driven bevel gear 19 rotates lead screw 16, threaded block 17 pushes piston rod 20 and piston plate 29 downwards within piston box 14. Cleaning water in piston box 14 enters annular pipe 23 via water supply pipe 22 and is sprayed out through nozzle 24 to rinse the inner wall and agitator. After cleaning, operator controls first motor 6 to reverse, winding reel 10 retracts connecting rope 30 to reset counterweight ring 32 and scraper ring 33, piston plate 29 moves upwards, water pipe 21 pumps clean water from water tank 3 into piston box 14 for the next cleaning cycle. In preparation for cleaning, staff can replace the scraper ring 33 periodically (every 6 months). When replacing it, staff first remove the sealing cover 4. Since the top of the guide rod 27 is not fixed to the sealing cover 4, the counterweight ring 32 can be slid off the guide rod 27. Then, the worn scraper ring 33 is removed using the fastening bolt 35 and replaced with a new wear-resistant rubber scraper ring 33. The scraper ring 33 is then reconnected and fixed to the counterweight ring 32 using the fastening bolt 35. The counterweight ring 32 is then put back onto the guide rod 27, and the sealing cover 4 is installed.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
