Description

Technical Field

[0001] This application relates to the field of homogenization emulsification, and in particular to a vacuum homogenization emulsification unit for the production of ear drops. Background Technology

[0002] Currently, in the production processes of food, cosmetics, pharmaceuticals, and fine chemicals, the mixing, dispersion, homogenization, and emulsification of materials are key steps that determine product quality. Vacuum homogenizing emulsifiers, which integrate multiple functions such as mixing, dispersion, homogenization, emulsification, and powder absorption, can efficiently achieve the fine processing of materials and have become an indispensable core production equipment in the aforementioned industries. By constructing a closed system, they can prevent materials from contacting the outside air, reduce impurity contamination, and meet the special requirements of different materials for the processing environment, greatly improving production efficiency and product stability. They play an irreplaceable role in the large-scale production of various creams, lotions, suspensions, and other products. The core working principle of the vacuum homogenizing emulsifier revolves around the coordinated operation of the emulsification pot and the homogenizer: After the material enters the emulsification pot, the central stirring mechanism at the top is activated. The scraper equipped with the mechanism can always conform to the shape of the inner wall of the stirring pot, and clean the material adhering to the pot wall in real time, preventing the material from drying or deteriorating due to long-term adhesion to the wall. At the same time, the material being scraped by the scraper continuously generates new interfaces, enhancing the contact and reaction efficiency between materials. Subsequently, under the combined action of the stirring blades and the rotating blades, the material undergoes multiple mechanical actions such as shearing, compression, and folding, achieving preliminary stirring and mixing. Guided by gravity and stirring force, it flows downward and finally gathers at the homogenizer below the pot. The homogenizer rapidly breaks the material into tiny particles with a particle size of only 200nm-2um through high-intensity mechanical shearing and pressure, allowing materials of different phases to be fully integrated to form a stable and uniform emulsion system, thereby completing the entire emulsification and homogenization process and ensuring that the product meets the preset fineness and stability standards. However, after the vacuum homogenizing emulsifier completes a single production run, the cleanliness of the equipment's interior gradually becomes a key bottleneck restricting the quality of subsequent production. Because the processed materials often contain viscous components such as oils, colloids, and high-molecular polymers, a large amount of residue adheres firmly to the inner walls of the emulsifying pot, feeding pipe, and discharge pipe after production. If this residue is not thoroughly removed, it will mix with new materials during the next run, leading to quality problems in the new batch of products, such as decreased purity, abnormal color, and unstable performance. In severe cases, it can even cause product scrapping, resulting in economic losses. Currently, The industry currently relies on a central agitator to drive water flow for cleaning equipment. This method can only remove loose residues from the internal surface of the equipment and is ineffective at cleaning sticky residues with strong adsorption properties. Especially in narrow pipes such as feed pipes and discharge pipes, there are dead zones in the water flow, and the residue accumulation is more serious. Long-term accumulation of residues not only affects product quality but also breeds microorganisms, increases the risk of equipment corrosion, and shortens the service life of the equipment. At the same time, frequent manual disassembly and cleaning will extend the production interval and reduce equipment utilization. Therefore, it is necessary to improve the design of existing technologies. Summary of the Invention

[0003] To facilitate the cleaning and maintenance of existing equipment, this application provides a vacuum homogenizing emulsifier unit for the production of ear drops.

[0004] The vacuum homogenizing emulsifier unit for producing ear drops provided in this application adopts the following technical solution: A vacuum homogenizing emulsifier for producing ear drops includes a base, a raw material tank, and an emulsifying tank. The raw material tank is fixedly installed on one side of the base. A conveying pump is installed inside the base, and the input end of the conveying pump is connected to the inside of the raw material tank. The emulsifying tank is fixedly installed on one side of the raw material tank. A self-cleaning feeding pipe is fixedly installed at the output end of the conveying pump, and the upper end of the self-cleaning feeding pipe is connected to the upper end of the emulsifying tank. A fixing frame is fixedly installed on the side of the base away from the raw material tank. The emulsifier body is fixedly installed on the outer side of the fixing frame. A self-cleaning discharge pipe is fixedly installed at the output end of the emulsifying tank. A support frame is fixedly installed on the top of the emulsifier body. A top plate is fixedly installed on the top of the support frame. A cleaning and lifting auxiliary mechanism is fixedly installed on the rear side of the top plate. A linkage disassembly and assembly mechanism is fixedly installed at the front end of the cleaning and lifting auxiliary mechanism. A stirring mechanism is fixedly installed at the bottom of the cleaning and lifting auxiliary mechanism. The main body of the stirring mechanism extends and rotates inside the emulsifying tank.

[0005] By adopting the above technical solution, during the application of this device, the base first provides a stable installation foundation for the raw material tank, conveying pump, and emulsification tank, avoiding the impact of vibration and displacement on production accuracy during equipment operation. The raw material tank stores the raw materials required for the production of ear drops, providing a stable material supply for production. When production begins, the conveying pump inside the base is started. The conveying pump draws raw materials through the connection between its input end and the inside of the raw material tank, and then pressurizes and conveys the raw materials to the self-cleaning feeding pipe through its output end. Under the pressure of the conveying pump, the raw materials enter the upper part of the emulsification tank along the self-cleaning feeding pipe, providing materials for subsequent emulsification operations. The emulsification tank, as the core emulsification container, performs preliminary treatment on the incoming raw materials. After the raw materials reach a suitable treatment state in the emulsification tank, the self-cleaning discharge pipe at the output end of the emulsification tank conveys the materials to the main body of the emulsification unit. The fixed frame provides stable support for the emulsifying unit, ensuring its stability during deep emulsification of materials, thus improving emulsification effect and product quality. Simultaneously, the support frame on top of the emulsifying unit supports the top plate, which provides a mounting platform for the cleaning and lifting auxiliary mechanism and the linkage disassembly mechanism. The cleaning and lifting auxiliary mechanism can adjust the position of the stirring mechanism, allowing it to rotate stably inside the emulsification tank, mixing the raw materials and promoting uniform emulsification, preventing uneven emulsification that could affect product quality. The linkage disassembly mechanism, in conjunction with the cleaning and lifting auxiliary mechanism, assists in the disassembly and assembly of relevant components when maintenance is required, reducing maintenance difficulty, shortening maintenance time, improving overall equipment operating efficiency, and ensuring the continuity and stability of the ear drop production process.

[0006] Optionally, the self-cleaning feeding pipe includes a main feeding pipe, which is fixedly installed in the middle of the back of the emulsification tank. The input end of the main feeding pipe is connected to the output end of the delivery pump, and the output end of the main feeding pipe is connected to the interior of the emulsification tank. The top of the main feeding pipe is covered by a feeding pipe sealing cover. A first motor is fixedly installed on the top of the feeding pipe sealing cover. A first rotating shaft is fixedly installed through the feeding pipe sealing cover at the output end of the first motor. A first cleaning scraper is fixedly connected at equal intervals on the outer surface of the first rotating shaft. The outer side of the first cleaning scraper is in close contact with the inner wall of the main feeding pipe. The top of the feeding pipe sealing cover is connected to the bottom of the cleaning lifting auxiliary mechanism.

[0007] By adopting the above technical solution, during the application of this device, its self-cleaning feeding pipe plays a key role in material conveying and equipment cleaning. When raw materials need to be conveyed to the emulsification tank, the raw materials output by the conveying pump enter the feeding main pipe. The feeding main pipe, as a material channel, stably guides the raw materials into the emulsification tank, ensuring that the raw materials are supplied to the emulsification operation area as needed. During the raw material conveying process, if it is necessary to clean the inner wall of the feeding main pipe simultaneously, the first motor at the top of the feeding pipe sealing cover can be started. The output end of the first motor drives the first rotating shaft to rotate. When the first shaft rotates, it simultaneously drives the first cleaning scraper fixed on the outer surface to move. Since the outer side of the first cleaning scraper is in contact with the inner wall of the feeding main pipe, it can scrape off the raw material residue adsorbed on the inner wall of the feeding main pipe in real time during rotation, avoiding the accumulation of residue that blocks the pipeline and affects the conveying efficiency. This improves efficiency and prevents residue from contaminating subsequent raw materials, thus ensuring the purity of the ear drops. It also solves the problem of having to stop the machine to disassemble the existing feeding pipe for cleaning. When the equipment needs deep maintenance, the cleaning lifting auxiliary mechanism can drive the feeding pipe sealing cover to rise and fall synchronously with the connection between the cleaning lifting auxiliary mechanism and the feeding pipe sealing cover. This will bring the first motor, the first rotating shaft and the first cleaning scraper out of the feeding pipe. The staff can directly inspect, wipe or replace the cleaning parts without disassembling the feeding pipe, which greatly reduces the difficulty of maintenance, shortens the maintenance time and ensures that the equipment can quickly return to production. At the same time, the feeding pipe sealing cover can also seal the top of the feeding pipe in the non-maintenance state to prevent external impurities from entering the pipe and contaminating the raw materials, further ensuring the cleanliness of the production process.

[0008] Optionally, a first support wheel is fixedly installed at the bottom end of the first rotating shaft, and a first support ball is rotatably connected to the outer side of the first support wheel in a ring at equal intervals. The outer side of the first support ball is in close contact with the inner wall of the lower end of the feeding pipe.

[0009] By adopting the above technical solution, during the operation of the self-cleaning feeding pipe, the bottom end of the first rotating shaft achieves stable rotation through the cooperation of the first support wheel and the first support ball. When the first motor drives the first rotating shaft to rotate to drive the first cleaning scraper to clean the inner wall of the feeding pipe, the first support wheel at the bottom end of the first rotating shaft rotates synchronously with the first rotating shaft. The first support ball, which is arranged in a ring on the outer side of the first support wheel, is in contact with the inner wall of the lower end of the feeding pipe. While the first support wheel rotates, it rolls along the inner wall of the feeding pipe. This rolling cooperation can provide stable bottom support for the first rotating shaft, preventing the first rotating shaft from shaking or shifting due to its long length or uneven force during rotation. This ensures that the first rotating shaft always maintains coaxial rotation, thereby allowing the first cleaning scraper to always be in close contact with the inner wall of the feeding pipe, and preventing the cleaning scraper from being damaged due to shaft shaking. The increased gap between the feed pipe and the inner wall ensures effective scraping of residue from the inner wall of the main feed pipe, avoiding cleaning dead zones. Simultaneously, the rolling contact of the first support ball significantly reduces frictional losses between the first shaft and the inner wall of the main feed pipe. Compared to sliding supports, this effectively reduces the operating load on the first motor, decreases component wear, extends the service life of the first shaft, the first support wheel, and the main feed pipe, and lowers equipment maintenance costs. Furthermore, even if a small amount of residual material remains in the main feed pipe or cleaning fluid is present during the cleaning process, the rolling of the first support ball prevents the accumulation of material or fluid at the support points, preventing jamming of the support structure and ensuring smooth rotation of the first shaft. This guarantees the continuous and stable operation of the self-cleaning feed pipe during material conveying and cleaning, providing reliable support for the smoothness of material conveying and the thoroughness of equipment cleaning during the production of ear drops.

[0010] Optionally, the self-cleaning discharge pipe includes a main discharge pipe, which is fixedly installed at the lower front end of the emulsification tank. The input end of the main discharge pipe is connected to the bottom of the emulsification tank, and the output end of the main discharge pipe is connected to the emulsification unit body. A discharge pipe sealing cover is fixedly installed on one side of the main discharge pipe, and a second motor is fixedly installed on the outside of the discharge pipe sealing cover. A second rotating shaft is fixedly installed through the discharge pipe sealing cover at the output end of the second motor. Second cleaning scrapers are fixedly installed on the outer surface of the second rotating shaft in a ring at equal intervals. The outer side of the second cleaning scraper is in close contact with the inner wall of the main discharge pipe.

[0011] By adopting the above technical solution, during the application of this device, its self-cleaning discharge pipe plays a key role in the material conveying and pipeline cleaning after emulsification. After the raw material of the ear drops in the emulsification tank has completed preliminary treatment, the material will enter the discharge main pipe from the bottom of the emulsification tank. The discharge main pipe, as a material conveying channel, stably guides the material to the emulsification unit body, providing a smooth material conveying path for subsequent deep processing and ensuring the continuous progress of the production process. During the material conveying process, in order to prevent the viscous components in the material from adsorbing onto the inner wall of the discharge main pipe and forming residue accumulation, the second motor on the outside of the discharge pipe sealing cover can be started. The output end of the second motor drives the second rotating shaft to rotate, and the second rotating shaft synchronously drives the second cleaning scraper arranged in a ring on its outer surface to rotate. Because the outer side of the second cleaning scraper is close to the inner wall of the discharge main pipe, the second cleaning scraper... The tightly fitting design allows for real-time scraping of material residue adsorbed on the inner wall of the main discharge pipe during rotation, preventing residue from clogging the pipe and affecting conveying efficiency. It also prevents residual residue from mixing into subsequent batches of material, ensuring the purity and quality of the ear drops. This solves the problem of frequent disassembly and cleaning required by traditional discharge pipes. Even during non-material conveying phases, periodically starting the second motor to drive the second cleaning scraper can perform preventative cleaning of the inner wall of the main discharge pipe, reducing the probability of long-term residue accumulation forming stubborn dirt. At the same time, the discharge pipe sealing cap effectively seals one side of the main discharge pipe, preventing external impurities from entering the pipe and contaminating the material. It also prevents leakage of cleaning water or residual material during the cleaning process, further improving the cleanliness and safety of the equipment operation and providing a reliable guarantee for the stable and efficient production of ear drops.

[0012] Optionally, a second support wheel is fixedly installed on the outer end of the second rotating shaft. The outer surface of the second support wheel is rotatably connected with second support balls arranged in a ring at equal intervals. The outer side of the second support balls is in close contact with the inner wall of the discharge main pipe.

[0013] By adopting the above technical solution, during the operation of the self-cleaning discharge pipe, the outer end of the second rotating shaft achieves stable rotation through the cooperation of the second support wheel and the second support ball. When the second motor drives the second rotating shaft to rotate and drive the second cleaning scraper to clean the inner wall of the discharge pipe, the second support wheel at the outer end of the second rotating shaft rotates synchronously with the second rotating shaft. The second support ball, which is arranged in a ring on the outer surface of the second support wheel, fits against the inner wall of the discharge pipe and rolls along the inner wall of the discharge pipe while the second support wheel rotates. This rolling cooperation can provide reliable end support for the second rotating shaft, avoiding wobbling or deviation of the second rotating shaft due to uneven force during rotation or its own length. This ensures that the second rotating shaft always maintains coaxial rotation, thereby allowing the second cleaning scraper to always fit tightly against the inner wall of the discharge pipe, preventing the cleaning scraper from sliding out of the pipe due to shaft wobbling. The gaps in the wall ensure thorough scraping of residue from the inner wall of the discharge main pipe, preventing dead corners from affecting the purity of subsequent materials. Simultaneously, the rolling contact of the second support ball significantly reduces frictional losses between the second shaft and the inner wall of the discharge main pipe. Compared to sliding contact, this effectively reduces the operating load on the second motor, decreases wear on the second shaft, second support wheel, and the inner wall of the discharge main pipe, extends the service life of each component, and lowers equipment maintenance costs. Furthermore, even if there are viscous components or water residue from cleaning within the discharge main pipe, the rolling of the second support ball prevents these substances from accumulating at the support points, preventing jamming of the support structure and ensuring smooth rotation of the second shaft. This guarantees the continuous and stable operation of the self-cleaning discharge pipe in the material conveying and cleaning process, providing solid support for the smoothness of material conveying and the thoroughness of pipeline cleaning in the production of ear drops.

[0014] Optionally, the cleaning lifting auxiliary mechanism includes a guide rail, which is fixedly installed at one rear end of the top plate. A third motor is fixedly installed at the top of the guide rail, and a first lead screw is fixedly installed through the guide rail at the output end of the third motor. A slider is threadedly connected to the outer surface of the first lead screw, and the slider is slidably connected to the inside of the guide rail. A connecting arm is fixedly installed on one side of the slider, and the stirring mechanism is fixedly installed at the bottom of the connecting arm.

[0015] By adopting the above technical solution, the cleaning and lifting auxiliary mechanism plays a key role in the position adjustment and maintenance of the stirring mechanism during the application of this device. When it is necessary to adjust the depth of the stirring mechanism in the emulsification tank to adapt to the emulsification requirements of different materials, or when it is necessary to clean and maintain the stirring mechanism, the third motor at the top of the guide rail can be activated. The output end of the third motor drives the first lead screw that passes through the guide rail to rotate. Since the outer surface of the first lead screw is threadedly connected to the slider, and the slider is slidably connected inside the guide rail, the rotation of the first lead screw is converted into the linear lifting and lowering motion of the slider along the guide rail through the threaded transmission. During the lifting and lowering process, the slider synchronously drives the fixed connecting arm on one side to move. Since the stirring mechanism is fixed at the bottom of the connecting arm, the connecting arm will drive the stirring mechanism to lift and lower together. This mechanical transmission method can accurately control the lifting and lowering height of the stirring mechanism. The system ensures that the mixing mechanism is in the optimal working position during emulsification, improving the uniformity of material mixing and emulsification effect. When maintenance of the mixing mechanism is required, the third motor simply drives the slider to rise, which can completely lift the mixing mechanism out of the emulsification tank. Workers can directly clean, inspect, or replace parts of the mixing mechanism without emptying the emulsification tank or disassembling the main body of the equipment. This significantly reduces the difficulty of maintenance operations, shortens maintenance time, and minimizes the impact of equipment downtime on production progress. Simultaneously, the guide rail's sliding constraint on the slider effectively prevents deviation or wobbling during slider lifting, ensuring a smooth lifting process for the mixing mechanism. This avoids damage to components caused by collisions between the mixing mechanism and the inner wall of the emulsification tank, extending the equipment's service life and providing a reliable guarantee for the stable operation and efficient maintenance of the equipment during the production of ear drops.

[0016] Optionally, a support rail is fixedly installed on the back of the top plate away from the guide rail, a support block is slidably connected inside the support rail, a support arm is fixedly installed on the outside of the support block, and the bottom of the support arm is fixedly connected to the top of the stirring mechanism on the side away from the connecting arm.

[0017] By adopting the above technical solution, during the application of this device, when the cleaning lifting auxiliary mechanism drives the stirring mechanism to rise and fall, the support rail, support block, and support arm together provide auxiliary support and stable guidance for the stirring mechanism. When the third motor drives the first lead screw to rotate, causing the slider, connecting arm, and stirring mechanism to rise and fall along the guide rail, the side of the top of the stirring mechanism away from the connecting arm will drive the support block to move synchronously through the support arm. The support block slides inside the support rail as the stirring mechanism rises and falls. The support rail, through its own structural constraints, provides precise guidance for the sliding of the support block, ensuring that the support block always moves along a fixed trajectory. Thus, the support arm forms stable support for one side of the stirring mechanism, preventing the stirring mechanism from tilting or swaying due to only one side being pulled by the connecting arm. This double-sided support method can... The system effectively distributes the force during the lifting and lowering of the mixing mechanism, preventing loosening or damage to the connecting parts due to uneven stress, and extending the service life of the mixing mechanism and connecting arm. Simultaneously, the cooperation between the support block and the support rail further enhances the stability of the mixing mechanism's lifting process, ensuring that the mixing mechanism does not collide with the inner wall of the emulsification tank when rising or falling, avoiding wear on components that could affect the equipment's operational accuracy. Furthermore, during emulsification, the support provided by the support arm and support block enhances the overall stability of the mixing mechanism, reducing the transmission of vibrations generated during rotation to the connecting arm and guide rail, lowering the operating load on the cleaning and lifting auxiliary mechanism, and ensuring stable operation of the entire equipment during the emulsification process. This provides reliable support for the continuity of ear drop production and the consistency of product quality.

[0018] Optionally, the stirring mechanism includes a sealing main cover, which is fixedly installed at the bottom of the support arm and the connecting arm. The sealing main cover covers the top of the emulsification tank. The feeding pipe sealing cover is fixedly connected to the rear side of the sealing main cover. A fourth motor is fixedly installed in the middle of the top of the sealing main cover. The output end of the fourth motor passes through the sealing main cover and is fixedly installed with a stirring frame. The main body of the stirring frame extends and rotates inside the emulsification tank. A side frame is fixedly installed at the front end of the top of the sealing main cover. A vacuum pump is fixedly installed on the outside of the side frame. The vacuum pump is connected to the inside of the emulsification tank.

[0019] By adopting the above technical solution, during the application of this device, its stirring mechanism plays a core role in material handling and environmental control within the emulsification tank. The sealing main cover, as the basic component of the stirring mechanism, covers the top of the emulsification tank during equipment operation, effectively isolating external air and impurities from entering the tank and preventing material contamination. Simultaneously, its connection with the feeding pipe sealing cover ensures the seal between the feeding pipe and the emulsification tank, preventing leakage of raw materials or cleaning water. When emulsification is required, the fourth motor located in the center of the top of the sealing main cover is activated. The output of the fourth motor drives the stirring frame, which runs through the sealing main cover, to rotate. The main body of the stirring frame rotates inside the emulsification tank, stirring and mixing the raw materials within, breaking the static state of the materials and promoting the mixing of different components. The materials are fully mixed, laying a uniform material foundation for subsequent emulsification and homogenization. This avoids poor emulsification due to uneven material mixing, which would affect the quality of the ear drops. In addition, the vacuum pump installed on the side frame at the top front of the sealed main cover can remove air from the emulsification tank before emulsification, creating a vacuum environment inside the tank. This vacuum setting prevents the raw materials from oxidizing when in contact with air during stirring and emulsification, reduces the generation of bubbles in the materials, and ensures the stability and purity of the ear drops. At the same time, the vacuum environment also inhibits the growth of microorganisms, further meeting the strict requirements for sterility and impurity-free production of ear drops. This ensures that the final product meets quality standards and provides excellent material conditions for the subsequent deep processing of the emulsification unit, ensuring the efficiency and stability of the entire production process.

[0020] Optionally, the stirring rack includes a stirring shaft, which is rotatably connected to the bottom of the sealed main cover. The top of the stirring shaft is connected to the bottom output end of the fourth motor. A stirring auger is fixedly installed at the bottom of the stirring shaft. Scrapers are fixedly connected to the outer surface of the stirring shaft in a ring at equal intervals. The outer side of the scrapers is in close contact with the inner wall of the emulsification tank. A stirring plate is fixedly connected to the inner side of the scrapers in a linear arrangement at equal intervals.

[0021] By adopting the above technical solution, during the application of this device, its stirring rack plays a key role in the mixing and cleaning of materials in the emulsification tank. When the fourth motor starts, its output end drives the stirring shaft to rotate. As the core transmission component of the stirring rack, the stirring shaft synchronously drives the bottom stirring auger and the inner scraper and agitator on the outer surface of the tank to move together. During the rotation of the stirring auger, its spiral structure generates an upward pushing force on the material at the bottom of the emulsification tank, allowing the raw materials deposited at the bottom of the emulsification tank to turn upward and fully contact and mix with the upper material, avoiding stratification due to gravity. This ensures that the raw materials in different positions in the tank are mixed evenly, providing a consistent material basis for subsequent emulsification and homogenization, effectively improving the quality stability of the ear drops product. At the same time, the inner scraper moves along with the material. When the stirring shaft rotates, its outer side fits tightly against the inner wall of the emulsification tank, effectively scraping away raw material residues adhering to the tank wall in real time. This prevents the raw materials from drying and hardening over time, thus avoiding waste and preventing dried residues from mixing with subsequent materials and affecting product purity. It also reduces the difficulty of equipment cleaning. In addition, the stirring plates on the inner side of the scraper inside the tank shear and fold the materials during rotation, further breaking up material clumps and enhancing the collision and mixing effect between materials. This results in a more uniform distribution of raw material components and improved stirring efficiency. This multi-component collaborative design not only efficiently completes the material stirring task but also simultaneously cleans the tank wall, reducing the workload of subsequent equipment cleaning and ensuring the continuity and stability of emulsification operations. This provides reliable support for the efficient advancement of ear drop production.

[0022] Optionally, the linkage assembly / disassembly mechanism includes a connecting frame and a rail frame. The connecting frame is fixedly installed at the front end of the connecting arm, and a connecting rod is fixedly connected to the front end of the connecting frame. A rack is fixedly installed at the lower front end of the connecting rod. The rail frame is fixedly installed on the front of the machine base. A second lead screw is rotatably connected inside the rail frame. A sliding block is threadedly connected to the outer surface of the second lead screw. A bending connecting rod is fixedly installed at the bottom of the sliding block. The bottom of the bending connecting rod is fixedly connected to the top of the discharge pipe sealing cover. A gear is fixedly connected to the side of the rail frame near the rack. The gear and the rack mesh with each other. The inner side of the gear and the outer end of the second lead screw are fixedly connected.

[0023] By adopting the above technical solution, during the application of this device, its linkage disassembly and assembly mechanism mainly realizes the automatic disassembly and assembly of the discharge pipe sealing cover during the maintenance of the self-cleaning discharge pipe. It works in coordination with the cleaning lifting auxiliary mechanism. When the cleaning lifting auxiliary mechanism drives the connecting arm to rise and fall to adjust the position of the stirring mechanism, the connecting frame at the front end of the connecting arm will synchronously drive the connecting rod to move. The rack at the lower end of the front of the connecting rod rises and falls with the connecting rod. Since the rack is meshed with the gear on one side of the rail frame, the rise and fall of the rack will drive the gear to rotate. The inner side of the gear is fixedly connected to the second lead screw inside the rail frame. Therefore, the rotation of the gear will synchronously drive the second lead screw to rotate. The sliding block threaded on the outer surface of the second lead screw will slide linearly along the rail frame when the second lead screw rotates. The bent connecting rod at the bottom of the sliding block moves with the sliding block, thereby driving the bent connecting rod to move. The bottom-connected discharge pipe sealing cover moves, allowing for separation or contact between the sealing cover and the main discharge pipe. This linked design eliminates the need for separate operation of the sealing cover; its removal and installation are synchronized via the cleaning lifting auxiliary mechanism. This significantly simplifies the maintenance process, avoiding the tedious manual disassembly of the sealing cover and saving maintenance time. Furthermore, the meshing transmission of gears and racks, and the threaded transmission of the second lead screw and sliding block ensure precise movement of the sealing cover, preventing misalignment during installation or removal that could lead to poor sealing or component collisions. This ensures a tight seal between the sealing cover and the main discharge pipe, preventing material leakage or impurities from entering. This further enhances the convenience of equipment maintenance and operational reliability, providing strong support for the efficient maintenance of the self-cleaning discharge pipe.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During the application of this technical solution, an automatic cleaning system consisting of a self-cleaning feeding pipe, a self-cleaning discharge pipe, and a stirring mechanism, combined with a cleaning lifting auxiliary mechanism, allows the cleaning solution to be pumped out by a conveying pump during use. At the same time, the motors are started to drive the cleaning scraper to rotate, performing preliminary automatic cleaning of the equipment interior. When thorough maintenance is required, the cleaning lifting auxiliary mechanism can quickly lift the stirring components and cleaning scraper out of the equipment, thus achieving the dual guarantee of automatic cleaning and rapid extraction. This solves the problems of existing technologies where automatic cleaning alone is insufficient to handle stubborn residues and manual disassembly and maintenance are inefficient. It ensures that there are no dead corners inside the equipment, making maintenance more thorough, while avoiding equipment failure due to untimely maintenance, ensuring the continuity of the ear drop production process, and meeting the requirements for equipment cleanliness and maintenance efficiency during production. 2. During the application of this technical solution, by setting up a collaborative structure of a cleaning lifting auxiliary mechanism and a linkage disassembly and assembly mechanism, in conjunction with automatic cleaning components, it is possible to quickly pull out the equipment, such as the mixing rack and cleaning scraper, by using the cleaning lifting auxiliary mechanism to drive the equipment body without disassembling the main body after automatic cleaning. At the same time, the linkage disassembly and assembly mechanism opens the discharge pipe sealing structure simultaneously, thereby achieving the effect of immediate and thorough maintenance and repair after automatic cleaning. This solves the problem of the disconnect between automatic cleaning and manual maintenance in the existing technology, which requires repeated disassembly and is time-consuming. It greatly improves maintenance efficiency and thoroughness, reduces equipment downtime, reduces the labor intensity of workers, and allows the equipment to return to production status more quickly, adapting to the pace of large-scale production of ear drops. 3. During the application of this technical solution, the integrated design of automatic cleaning components and removable maintenance structure allows for daily cleaning to be completed by the automatic cleaning system. During regular thorough maintenance, each cleaning scraper and stirring component can be quickly pulled out by the lifting mechanism, allowing staff to directly and meticulously clean and inspect the exposed components. This achieves the effect of balancing efficient daily cleaning with thorough regular maintenance, solving the problems of either incomplete cleaning or cumbersome maintenance in existing technologies. It meets the dual requirements of ear drop production for equipment cleanliness and ease of maintenance, ensuring long-term stable operation of the equipment and avoiding product quality issues caused by inadequate equipment cleaning or untimely maintenance, thus providing reliable equipment support for ear drop production.

[0044] The implementation principle of the vacuum homogenizing emulsifier unit for ear drop production in this application embodiment is as follows: When using this device, the first step is to prepare for startup. The operator must check the connection status of each structure, including the self-cleaning feed pipe 5, the self-cleaning discharge pipe 8, the stirring mechanism 13, and the vacuum pump 135, to ensure that the feed pipe sealing cap 52 of the self-cleaning feed pipe 5 tightly covers the top of the feed main pipe 51, the discharge pipe sealing cap 82 of the self-cleaning discharge pipe 8 stably seals one side of the discharge main pipe 81, and the sealing cap 131 of the stirring mechanism 13 completely covers the top of the emulsification tank 3. The vacuum pump 135 is connected to the first motor 53, the second motor 83, the third motor 112, and the fourth motor 132. All components are in the off state, and the raw material tank 2 contains a sufficient amount of ear drop raw material that meets the production standards. By setting the base 1, a stable installation foundation is provided for the raw material tank 2, the delivery pump 4, and the emulsification tank 3, preventing the equipment from shifting due to vibration during subsequent operation. At the same time, by setting the cooperation structure between the support frame 9 and the top plate 10, the top plate 10 is fixed to the top of the support frame 9. The top plate 10 provides a precise installation carrier for the guide rail 111 and the support rail 116 of the cleaning lifting auxiliary mechanism 11 and the rail frame 122 of the linkage disassembly and assembly mechanism 12. This ensures the overall structural stability from the initial stage before the equipment starts up, thereby reducing the probability of failure during subsequent operation. After preparation, the device enters the material conveying stage. At this time, the conveying pump 4 is started. The conveying pump 4, through its own power, pressurizes and conveys the ear drop liquid raw material in the raw material tank 2 to the inner feed main pipe 51 of the self-cleaning feed pipe 5. Simultaneously, the first motor 53 of the self-cleaning feed pipe 5 is started. After the first motor 53 starts, its output end drives the first rotating shaft 54 ​​to rotate. During the rotation of the first rotating shaft 54, the first cleaning scraper 55 fixed on its outer surface and the first support wheel 56 fixed at the bottom move together. By setting a cooperative structure between the first support wheel 56 and the first support ball 57, the first support ball 57 on the outer surface of the first support wheel 56 rolls along the inner wall of the feed main pipe 51. This reduces frictional wear between the first rotating shaft 54 ​​and the inner wall of the feed main pipe 51 during rotation, and ensures the rotational accuracy of the first rotating shaft 54, preventing the first cleaning scraper 55 from not adhering tightly to the inner wall of the feed main pipe 51 due to shaking. The scraper 55 rotates against the inner wall of the feeding pipe 51 under the drive of the first rotating shaft 54, scraping off the raw material residue adsorbed on the inner wall of the feeding pipe 51 in real time while the raw material is being conveyed. This prevents the residue from accumulating and clogging the pipe in the feeding pipe 51, affecting the raw material conveying efficiency, and also avoids the residue from mixing into the raw material being conveyed later, affecting the purity of the material. This solves the problem of incomplete cleaning of the feeding pipe residue in the prior art. Under the pressure of the conveying pump 4, the raw material continuously enters the emulsification tank 3 through the feeding pipe 51. The emulsification tank 3, as the core container for emulsifying the ear drops raw material, provides an independent operating space for the subsequent emulsification process through its own closed structure. When the raw material in the emulsification tank 3 reaches the preset processing liquid level, the conveying pump 4 and the first motor 53 are turned off. At this time, the sealing main cover 131 of the stirring mechanism 13 prevents the raw material in the emulsification tank 3 from leaking out through its own sealing function, while blocking impurities in the outside air from entering the interior of the emulsification tank 3, ensuring the cleanliness of the raw material before emulsification. Next, the device enters the vacuum stirring and emulsification stage. First, the vacuum pump 135 of the stirring mechanism 13 is started. The vacuum pump 135 extracts air from the emulsification tank 3 through a communication structure with the inside of the emulsification tank 3, creating a vacuum environment inside the emulsification tank 3. This vacuum setting prevents the raw materials from oxidizing due to contact with air during the emulsification process, and also prevents microorganisms or impurities in the air from contaminating the raw materials, thereby meeting the strict requirements for a sterile environment in the production of ear drops. Subsequently, the fourth motor 132 is started. The output end of the fourth motor 132 drives the stirring shaft 1331 of the stirring frame 133 to rotate. When the stirring shaft 1331 rotates, it simultaneously drives the stirring auger fixed on the outer surface. 1332. The scraper 1333 and the stirring plate 1334 move together. The stirring auger 1332 uses its spiral structure to push the raw material at the bottom of the emulsifying tank 3 upward, so that the raw material in different positions in the emulsifying tank 3 can be evenly distributed, laying the foundation for the uniformity of the subsequent emulsification process. The scraper 1333 rotates against the inner wall of the emulsifying tank 3 under the drive of the stirring shaft 1331, scraping off the raw material residue adsorbed on the inner wall of the emulsifying tank 3 in real time, preventing the raw material from drying and becoming difficult to clean after long-term adhesion to the wall, and also avoiding the dried raw material from affecting the emulsification effect, thus solving the problem of difficult residue cleaning in existing emulsifying pots. The stirring plate 1334, during the rotation, stirs the raw material in the emulsifying tank 3. The materials undergo shearing and folding operations to promote thorough mixing and ensure uniformity in the subsequent emulsification process. After the raw materials are mixed, the emulsifying unit 7 is started to work with the emulsifying tank 3 for emulsification. At the same time, the passage of the self-cleaning discharge pipe 8 is opened. The pre-treated material in the emulsifying tank 3 enters the discharge main pipe 81 of the self-cleaning discharge pipe 8 under the pushing action of the stirring auger 1332. At this time, the second motor 83 is started. The output end of the second motor 83 drives the second rotating shaft 84 to rotate. The second rotating shaft 84 synchronously drives the second cleaning scraper 85 on the outer surface and the second support wheel 86 on the outer end to rotate. By setting the second support wheel 86 and the second support... With the cooperation of the ball bearing 87, the second support ball bearing 87 rolls along the inner wall of the discharge pipe 81 to ensure the rotational stability of the second rotating shaft 84. The second cleaning scraper 85 rotates against the inner wall of the discharge pipe 81 to scrape off the material residue adsorbed on the inner wall of the discharge pipe 81, preventing the residue from mixing into the material entering the emulsifying unit body 7 later, and also preventing the residue from clogging the discharge pipe 81. This solves the problem of cleaning dead corners in the discharge pipe in the prior art. Under the propulsion of its own gravity and the stirring auger 1332, the material enters the emulsifying unit body 7 through the discharge pipe 81. The emulsifying unit body 7 performs deep processing on the material, and finally forms a stable emulsion system that meets the requirements of the ear drop product. After the emulsification process is completed, the unit enters the equipment cleaning and maintenance stage. First, the emulsification unit body 7 and the fourth motor 132 are shut down. If internal cleaning of the equipment is required, the existing conveying pump 4 can be used to draw external cleaning water. Under the pressure of the conveying pump 4, the cleaning water sequentially enters the main feed pipe 51 of the self-cleaning feed pipe 5, the emulsification tank 3, and the main discharge pipe 81 of the self-cleaning discharge pipe 8. At the same time, the first motor 53 of the self-cleaning feed pipe 5, the second motor 83 of the self-cleaning discharge pipe 8, and the fourth motor of the stirring mechanism 13 are restarted. 132. The first motor 53 drives the first cleaning scraper 55 to rotate inside the feeding pipe 51, working with the cleaning solution to thoroughly flush the inner wall of the feeding pipe 51, ensuring no residue remains inside the feeding pipe 51; the second motor 83 drives the second cleaning scraper 85 to rotate inside the discharge pipe 81, working with the cleaning solution to thoroughly clean the inner wall of the discharge pipe 81; the fourth motor 132 drives the inner scraper 1333 to rotate inside the emulsification tank 3, scraping off any residue remaining on the inner wall of the emulsification tank 3, while simultaneously the rotating auger 1332 and the agitator 1334 drive the cleaning solution in the emulsification tank 3. The cleaning solution flows freely inside the emulsifying tank 3, ensuring that the cleaning solution reaches every area within the tank, feed pipe, and discharge pipe, achieving thorough cleaning without any blind spots. This completely removes any sticky residue adsorbed inside the equipment. After cleaning, the discharge passage of the discharge main pipe 81 is opened to completely drain the wastewater generated during cleaning, preventing wastewater residue from affecting the quality of subsequent products. If further detailed cleaning and maintenance is required, after the cleaning water has been completely drained, the third motor 112 of the cleaning lifting auxiliary mechanism 11 is started. The output of the third motor 112 drives the first motor inside the guide rail 111. When the lead screw 113 rotates, since the first lead screw 113 is threadedly connected to the slider 114 and the slider 114 is slidably connected to the inside of the guide rail 111, when the first lead screw 113 rotates, it drives the slider 114 to slide upward along the guide rail 111. During the upward sliding process of the slider 114, it simultaneously drives the connecting arm 115 fixed on one side to move upward. The connecting arm 115 drives the sealing main cover 131 of the stirring mechanism 13 and the feeding pipe sealing cover 52 of the self-cleaning feeding pipe 5 to rise upward together, so that the stirring frame 133 is completely raised outside the emulsification tank 3 and the feeding pipe sealing cover 52 is removed from the top of the feeding main pipe 51.Simultaneously, when the connecting arm 115 moves upward, it drives the connecting frame 121 of the linkage disassembly mechanism 12 to rise synchronously. The connecting frame 121 drives the connecting rod 123 fixed at the front end to move upward. The connecting rod 123 drives the rack 124 fixed at the bottom to move upward. Since the rack 124 is meshed with the gear 128 on one side of the rail frame 122, when the rack 124 moves upward, it drives the gear 128 to rotate. The rotation of the gear 128 synchronously drives the second lead screw 125 fixed on the inner side to rotate. The second lead screw 125 is threadedly connected to the sliding block 126, and the sliding block 126 is slidably connected to the inside of the rail frame 122. The rotation of the second lead screw 125 drives the sliding block 126 to slide along the rail frame 122. The sliding block 126 drives the bent connecting rod 127 fixed at the bottom to move. The bent connecting rod 127 drives the discharge pipe sealing cover 82 of the self-cleaning discharge pipe 8 to move synchronously, so that the discharge pipe sealing cover 82 is disengaged from the discharge main pipe 81. Through this linkage, The moving structure design allows workers to directly and meticulously wipe and inspect the exposed first cleaning scraper 55, second cleaning scraper 85, and inner scraper 1333, completing thorough cleaning and maintenance. The entire maintenance process requires no disassembly of the main equipment structure or the construction of a complex work platform, significantly reducing maintenance time and improving equipment utilization. This solves the problems of inconvenient maintenance operations and excessive downtime in existing technologies. After maintenance, the third motor 112 is reverse-started to reset all moving structures, restoring the equipment's sealed state and ensuring rapid deployment to the next production cycle. During application, regulating valves are installed at each pipeline to close pipes or control flow rate. In specific applications, the gears 128 and rack 124 are covered with an outer shell, which improves aesthetics while protecting them.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
