Description

Technical Field

[0001] This invention relates to the field of dispersion technology, and more particularly to a carbomer dispersion tank and method for preventing clumping. Background Technology

[0002] Carbomer is a type of polymer material formed by cross-linking and polymerization of acrylic acid. It belongs to the category of synthetic thickeners and gel matrices and is widely used in cosmetics, pharmaceuticals, and personal care products. It has excellent thickening, suspending, emulsifying, and film-forming properties. It can rapidly swell in water to form a transparent gel and is gentle on the skin with low irritation.

[0003] During use, carbomer, due to its high absorbency and strong hydrophilicity, readily absorbs water and swells rapidly on its surface when added directly to water or other aqueous media, forming a viscous gel film that encapsulates the unwetted powder particles, leading to clumping or "fish-eye" phenomena. This clumping not only hinders further contact and uniform dispersion of the carbomer particles with water but also significantly prolongs dissolution time, potentially causing excessively high local concentrations and system inhomogeneity, severely impacting the transparency, viscosity stability, and performance of the final product. Summary of the Invention

[0004] The purpose of this invention is to provide a carbomer dispersion tank and method for preventing clumping, which aims to pre-disperse carbomer before it comes into contact with a liquid and then mix it, thereby enabling better integration with the liquid, reducing clumping, and improving production quality.

[0005] To achieve the above objectives, in a first aspect, the present invention provides an anti-caking carbomer dispersion tank, comprising a base, a dispersion shell, a feeding assembly, a dispersion component, and a stirring assembly. The dispersion shell is fixed on the base. The feeding assembly includes a hopper, a feeding valve, a conical baffle, a support ring, and a scraper structure. The feeding valve is disposed on the dispersion shell. The support ring is disposed outside the feeding valve. The conical baffle is disposed inside the support ring. The scraper structure is used to scrape off carbomer agglomerates on the conical baffle. The hopper is connected to the feeding valve. The dispersion assembly includes a support cylinder and a screw. The support cylinder is fixed inside the dispersion shell and located below the conical baffle. The screw is rotatably disposed inside the support cylinder. The stirring assembly includes a stirring motor, a rotating ring, and stirring blades. The stirring motor is disposed at the bottom of the dispersion shell. The rotating ring is connected to the output end of the stirring motor and is located outside the support cylinder. The screw is connected to the output end of the stirring motor. The stirring blades are disposed outside the rotating ring.

[0006] The feeding valve includes a valve body, a stopper rod, a sliding ring, an electromagnetic control structure, and a return spring. The valve body is fixed on the dispersion shell, the stopper rod is fixed in the cavity of the valve body, the sliding ring is slidably disposed on one side of the stopper rod, the return spring is disposed on one side of the sliding ring, and the electromagnetic control structure is used to control the opening and closing of the sliding ring.

[0007] The conical baffle includes a lifting motor, a lifting screw, and a baffle body. The baffle body is slidably connected to the stop rod, the lifting screw is threadedly connected to the baffle body, and the output end of the lifting motor is connected to the lifting screw.

[0008] The scraper structure includes a gear, a gear ring, a moving block, a control cylinder, and a scraper. The gear ring is rotatably disposed on one side of the support ring, and the gear meshes with the gear ring. The moving block is slidably disposed on one side of the gear ring. The output end of the control cylinder is connected to the moving block, and the scraper is disposed on the moving block.

[0009] The scraper includes a scraper body, a support rod, a second elastic element, and a heating structure. The support rod is connected to the output end of the control cylinder. The scraper body is slidably disposed on the support rod. The second elastic element is disposed between the scraper body and the support rod. The heating structure is disposed on the scraper body.

[0010] The scraper structure further includes a negative pressure pipe, a negative pressure pump, and a collection box. The negative pressure pipe is located on one side of the scraper body, the negative pressure pump is connected to the negative pressure pipe, and the collection box is connected to the negative pressure pump.

[0011] The feeding assembly also includes a retaining ring, which is disposed on the outside of the toothed ring to prevent splashed liquid from entering the support ring.

[0012] The dispersion component further includes a conical ring, which is disposed at the top of the support cylinder.

[0013] The stirring assembly further includes guide vanes, which are fixed above the support ring and located on one side of the conical ring.

[0014] Secondly, the present invention also provides a carbomer dispersion method for preventing clumping, comprising: Place the carbomer into the hopper and open the discharge valve to allow the carbomer to disperse into a ring-shaped flow along the conical baffle. The stirring motor is started to drive the screw to rotate, which causes the screw to push the liquid medium in the support cylinder to rise, mix with the carbomer flowing down in an annular shape, and then discharge to both sides; The stirring motor drives the stirring blades to rotate, further mixing the carbomer and the liquid medium.

[0015] The present invention provides a carbomer dispersion tank and method for preventing agglomeration, wherein the feeding component is used to achieve uniform and controllable feeding of carbomer powder and effectively prevent it from accumulating and agglomerating at the feeding port.

[0016] The hopper stores the carbomer powder to be dispersed and is connected to the discharge valve via a pipe. The discharge valve is installed on the top or side wall of the dispersion shell and controls the start, stop, and flow rate of the material. A support ring is provided on the outside of the discharge valve to support and fix the internal structure. The conical baffle is located inside the support ring and has an inverted conical structure. Its function is to guide the carbomer powder to the lower dispersion area in a circular flow. After a period of use, to prevent the carbomer from clumping on the surface of the conical baffle due to moisture absorption or static electricity, this invention specifically provides a scraper structure. This scraper can rotate around an axis and closely adheres to the surface of the conical baffle to scrape off the attached or clumped material in real time, ensuring that the discharge channel is unobstructed.

[0017] The dispersion component is located directly below the conical baffle and is used for primary crushing and pre-dispersion of the initially falling carbomer. This component includes a support cylinder fixed inside the dispersion shell and a screw rotatably mounted within the support cylinder. The support cylinder serves as the mounting carrier for the screw, and its interior forms a closed spiral channel. The screw is driven to rotate by a drive mechanism, which can cause the liquid medium below to surge upwards and combine with the annularly falling material to form a circulation.

[0018] The stirring assembly, located at the bottom of the dispersion shell, is responsible for the efficient and uniform mixing of the initially dispersed carbomer with the solvent (such as water or other matrix). The stirring motor is installed inside the bottom of the dispersion shell, with its output extending upwards, simultaneously driving two functional components: firstly, the output connects to the screw, enabling linkage between the dispersion and stirring assemblies; secondly, the output also connects to a rotating ring surrounding the outside of the support cylinder, which rotates synchronously with the motor and has multiple stirring blades evenly arranged around its outer circumference. The stirring blades employ a specific angle and shape design (such as paddle, anchor, or turbine type) to create a strong three-dimensional flow field within the tank, promoting rapid wetting, swelling, and uniform distribution of carbomer particles in the liquid medium, completely preventing agglomeration.

[0019] This invention achieves continuous, automated, and efficient processing of carbomer from feeding to dispersion by using the anti-caking scraping design of the feeding component, the primary crushing function of the dispersion component, and the efficient mixing effect of the stirring component, thus significantly improving dispersion quality and production efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] First Embodiment Please see Figures 1-6 This invention provides an anti-caking carbomer dispersion tank, comprising a base 101, a dispersion shell 102, a feeding assembly 103, a dispersion assembly 104, and a stirring assembly 105. The dispersion shell 102 is fixed to the base 101. The feeding assembly 103 includes a material box 106, a feeding valve 107, a conical baffle 108, a support ring 109, and a scraper structure 110. The feeding valve 107 is disposed on the dispersion shell 102, the support ring 109 is disposed outside the feeding valve 107, the conical baffle 108 is disposed inside the support ring 109, and the scraper structure 110 is used to scrape off carbomer agglomerates on the conical baffle 108. The material box 106 and the feeding assembly 105 are connected. The material valve 107 is connected; the dispersion assembly 104 includes a support cylinder 111 and a screw 112. The support cylinder 111 is fixed inside the dispersion shell 102 and located below the conical baffle 108. The screw 112 is rotatably disposed inside the support cylinder 111. The stirring assembly 105 includes a stirring motor 113, a rotating ring 114, and stirring blades 115. The stirring motor 113 is disposed at the bottom of the dispersion shell 102. The rotating ring 114 is connected to the output end of the stirring motor 113 and is located outside the support cylinder 111. The screw 112 is connected to the output end of the stirring motor 113. The stirring blades 115 are disposed outside the rotating ring 114.

[0032] In this embodiment, the feeding component 103 is used to achieve uniform and controllable feeding of carbomer powder and effectively prevent it from accumulating and clumping at the feeding port.

[0033] The hopper 106 stores the carbomer powder to be dispersed and is connected to the discharge valve 107 via a pipe. The discharge valve 107 is installed on the top or side wall of the dispersion shell 102 and is used to control the start, stop, and flow rate of the material. A support ring 109 is provided on the outside of the discharge valve 107 to support and fix the internal structure. The conical baffle 108 is located inside the support ring 109 and has an inverted conical structure. Its function is to guide the carbomer powder to the lower dispersion area in a circular flow. After a period of use, in order to prevent the carbomer from clumping on the surface of the conical baffle 108 due to moisture absorption or static electricity, the present invention specifically provides a scraper structure 110. The scraper 128 can rotate around an axis and closely adheres to the surface of the conical baffle 108 to scrape off the attached or clumped material in real time, ensuring that the discharge channel is unobstructed.

[0034] The dispersion component 104 is located directly below the conical baffle 108 and is used for primary crushing and pre-dispersion of the initially falling carbomer. This component includes a support cylinder 111 fixed inside the dispersion shell 102 and a screw 112 rotatably disposed within the support cylinder 111. The support cylinder 111 serves as the mounting carrier for the screw 112, and its interior forms a closed spiral channel. The screw 112 is driven to rotate by a drive mechanism, which can cause the liquid medium below to surge upwards and combine with the annularly falling material to form a circulation.

[0035] The stirring assembly 105 is located at the bottom of the dispersion shell 102 and is responsible for efficiently and uniformly mixing the initially dispersed carbomer with the solvent (such as water or other matrix). The stirring motor 113 is installed inside the bottom of the dispersion shell 102, with its output end extending upwards. It simultaneously drives two functional components: on one hand, the output end connects to the screw 112, enabling linkage between the dispersion assembly 104 and the stirring assembly 105; on the other hand, the output end also connects to a rotating ring 114 surrounding the outside of the support cylinder 111. This rotating ring 114 rotates synchronously with the motor, and multiple stirring blades 115 are evenly arranged on its outer circumference. The stirring blades 115 employ a specific angle and shape design (such as paddle, anchor, or turbine type) to create a strong three-dimensional flow field within the tank, promoting rapid wetting, swelling, and uniform distribution of carbomer particles in the liquid medium, completely preventing agglomeration.

[0036] This invention achieves continuous, automated, and efficient processing of carbomer from feeding to dispersion through the anti-caking and scraping design of the feeding component 103, the primary crushing function of the dispersion component 104, and the efficient mixing effect of the stirring component 105, significantly improving dispersion quality and production efficiency.

[0037] The feeding valve 107 includes a valve body 116, a stopper rod 117, a sliding ring 118, an electromagnetic control structure 119, and a return spring 120. The valve body 116 is fixed on the dispersion shell 102, the stopper rod 117 is fixed in the cavity of the valve body 116, the sliding ring 118 is slidably disposed on one side of the stopper rod 117, the return spring 120 is disposed on one side of the sliding ring 118, and the electromagnetic control structure 119 is used to control the opening and closing of the sliding ring 118.

[0038] The valve body 116 is a hollow cylindrical structure, one end of which is firmly installed and sealed to the top or side wall of the dispersion shell 102, forming an inlet or outlet interface for the material channel. The valve body 116 has an internal cavity for accommodating other functional components, ensuring a compact overall structure and good airtightness. The stopper rod 117 is fixedly positioned at the center of the cavity of the valve body 116, with its axis aligned with the material flow direction. The surface of the stopper rod 117 is precision-machined, possessing good smoothness and wear resistance. It serves as the guiding core for the movement of the sliding ring 118, and in the closed state, it cooperates with the sliding ring 118 to form a tight sealing surface, effectively blocking the passage of material.

[0039] The sliding ring 118 is sleeved and slidably installed on one side of the stopper rod 117 (usually near the material outlet end). Its inner hole fits tightly with the stopper rod 117, and its outer edge forms an openable and closable annular channel with the inner wall of the valve body 116. When the sliding ring 118 is in the closed position, the annular channel is completely blocked, preventing carbomer powder from falling. When the sliding ring 118 is driven to move in the opening direction, the annular channel opens, allowing the material to flow out evenly and continuously. The sliding ring 118 is made of corrosion-resistant, low-friction engineering plastics or metal composite materials, which ensures long-term operational stability and reduces the risk of jamming caused by powder adhesion.

[0040] The return spring 120 is located on one side of the sliding ring 118 (usually at the rear end away from the material flow channel), with one end abutting against the sliding ring 118 and the other end fixed to the limiting structure inside the valve body 116. When no external driving force is applied, the return spring 120 always applies a spring force to the sliding ring 118 toward the closed position, ensuring that the discharge valve 107 automatically resets to the closed state in the event of a power failure or malfunction, thereby improving the safety and reliability of the system.

[0041] The electromagnetic control structure 119 includes components such as an electromagnetic coil, an armature, and a linkage push rod, and is installed outside the valve body 116 or embedded inside the valve body 116 housing. When the control system issues a feeding command, the electromagnetic coil is energized to generate magnetic force, attracting the armature to drive the linkage push rod to push the sliding ring 118 to overcome the elastic force of the return spring 120 and slide along the axial direction of the stopper rod 117, thereby opening the feeding channel; when the command ends or an emergency stop is required, the electromagnetic coil is de-energized, the magnetic force disappears, and the return spring 120 immediately pushes the sliding ring 118 back to its original position, quickly closing the channel.

[0042] The conical baffle 108 includes a lifting motor 121, a lifting screw 122, and a baffle body 123. The baffle body 123 is slidably connected to the stopper rod 117, the lifting screw 122 is threadedly connected to the baffle body 123, and the output end of the lifting motor 121 is connected to the lifting screw 122.

[0043] The baffle body 123 has an inverted conical or near-conical structure with a smooth surface and a certain angle, which facilitates the natural sliding of powder along its inclined surface and avoids local accumulation of material. The baffle body 123 is slidably connected to the stopper rod 117 in the aforementioned feed valve 107 via a guide hole or groove, allowing it to rise and fall smoothly in the vertical direction without deflection or jamming. This sliding connection method ensures structural stability and provides a mechanical basis for the dynamic adjustment of the baffle position.

[0044] The lifting screw 122 is vertically positioned at the center or side of the baffle body 123 and forms a precise threaded connection with the internal threaded hole on the baffle body 123. When the lifting screw 122 rotates, it drives the baffle body 123 to move up and down along the axial direction of the stopper rod 117, thereby changing the relative distance between the conical baffle 108 and the discharge port. This design allows for flexible adjustment of the discharge gap according to the particle size, moisture content, or flowability of different batches of carbomer, optimizing the material flow state and preventing blockage due to excessively small gaps or dust dispersion due to excessively large gaps.

[0045] The lifting motor 121 is fixedly installed on the top of the dispersion shell 102 or on the support frame, and its output end is connected to the upper end of the lifting screw 122 via a coupling or directly. By precisely controlling the forward and reverse rotation and running time of the lifting motor 121 through the control system, the automatic lifting and lowering adjustment of the conical baffle 108 can be realized, thereby changing the area of ​​the discharge port to change the feeding speed.

[0046] The scraper structure 110 includes a gear 124, a gear ring 125, a moving block 126, a control cylinder 127, and a scraper 128. The gear ring 125 is rotatably disposed on one side of the support ring 109. The gear 124 meshes with the gear ring 125. The moving block 126 is slidably disposed on one side of the gear ring 125. The output end of the control cylinder 127 is connected to the moving block 126. The scraper 128 is disposed on the moving block 126.

[0047] The gear ring 125 is an annular component, rotatably mounted on one side of the support ring 109 (usually located around the conical baffle 108), with continuous teeth on its inner or outer side. The gear 124 is driven by an independent small drive motor or a transmission mechanism linked to the main stirring system, meshing with the gear ring 125, thereby causing the gear ring 125 to rotate around the central axis of the conical baffle 108. The rotation of the gear ring 125 provides the basis for the circumferential motion of the scraper 128.

[0048] A radially extending guide rail or groove is provided on one side of the gear ring 125 (usually on its outer or inner edge), and the moving block 126 is slidably disposed on the guide rail and can reciprocate in the radial direction. The control cylinder 127 is fixed to the support structure, and its piston rod 117 (i.e., the output end) is rigidly connected to the moving block 126. When the control cylinder 127 extends, it can push the moving block 126 to slide radially along the gear ring 125, thereby driving the scraper 128 on it to approach the surface of the conical baffle 108.

[0049] The scraper 128 is fixedly installed at one end of the moving block 126 facing the conical baffle 108. Its cutting edge is in close contact with or very close to the surface of the baffle. The material is preferably polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMWPE), or stainless steel coated flexible material, which has good wear resistance and chemical stability, and can effectively scrape off the attached material without damaging the surface of the baffle. During operation, the scraper 128 is driven by the control cylinder 127 to first press radially against the surface of the conical baffle 108, and then, with the rotation of the toothed ring 125, it achieves 360° circumferential scraping, thoroughly removing any clumps, hanging materials, or accumulated dust that may form on the baffle.

[0050] The scraper 128 includes a scraper body 129, a support rod 130, a second elastic element 131, and a heating structure 132. The support rod 130 is connected to the output end of the control cylinder 127. The scraper body 129 is slidably disposed on the support rod 130. The second elastic element 131 is disposed between the scraper body 129 and the support rod 130. The heating structure 132 is disposed on the scraper body 129.

[0051] The support rod 130 serves as the main load-bearing component of the scraper 128. One end is rigidly connected to the output end (piston rod 117) of the aforementioned control cylinder 127, transmitting the pushing and pulling force of the cylinder to achieve the radial feeding and retracting motion of the scraper 128 as a whole. The support rod 130 is made of high-strength stainless steel or lightweight alloy, possessing good rigidity and corrosion resistance, ensuring structural stability during long-term operation.

[0052] The scraper body 129 is slidably mounted on the support rod 130, and low-friction, high-precision relative movement is typically achieved through a guide sleeve or linear guide rail. The front end of the scraper body 129 is provided with an arc-shaped or conical scraping blade that matches the surface contour of the conical baffle 108. The material is preferably a high-temperature resistant, low-friction, and antistatic engineering composite material (such as a metal matrix filled with PTFE, PEEK, or silicone), which can effectively peel off the attached material while avoiding scratching the baffle surface.

[0053] A second elastic element 131 (such as a compression spring, disc spring, or elastic rubber pad) is provided between the scraper body 129 and the support rod 130. Its function is to provide a constant preload so that the scraper body 129 always adheres to the surface of the conical baffle 108 with appropriate pressure.

[0054] Furthermore, to address the issue of carbomer easily absorbing water and swelling in humid environments, forming tough clumps, this invention integrates a heating structure 132 inside or on the surface of the scraper body 129. This heating structure 132 can be an embedded heating wire, a flexible heating film, or a heat-conducting oil channel, and is precisely temperature-controlled (typically maintained within the range of 40–70°C) via an external power supply or temperature control system. During the scraping process, the heating structure 132 locally heats the scraper body 129, which on the one hand softens or dries the adhered wet clumps, reducing their adhesion strength; on the other hand, it inhibits the localized gelation of carbomer due to frictional heat during scraping, thereby improving scraping efficiency and preventing secondary adhesion.

[0055] The scraper structure 110 also includes a negative pressure pipe 133, a negative pressure pump 134, and a collection box 135. The negative pressure pipe 133 is disposed on one side of the scraper body 129. The negative pressure pump 134 is connected to the negative pressure pipe 133, and the collection box 135 is connected to the negative pressure pump 134.

[0056] The negative pressure pipe 133 is arranged along one side of the scraper body 129 (usually located behind or above the scraper blade), with its inlet end close to the scraping operation area. The inner wall of the pipe is smooth to reduce resistance. The negative pressure pump 134 (such as a miniature vortex blower or diaphragm vacuum pump) is connected to the negative pressure pipe 133 and is activated when the scraper 128 is working, forming a local negative pressure zone near the scraping point to immediately suck up the fine powder or debris raised by the scraping action. The sucked-up material is transported to the collection box 135 through the negative pressure pipe 133. The collection box 135 is sealed to the outlet end of the negative pressure pump 134 and may be equipped with a filter screen or cyclone separation structure inside to intercept and temporarily store the recovered carbomer powder for subsequent reuse or centralized treatment.

[0057] The feeding assembly 103 also includes a retaining ring 136, which is disposed on the outside of the toothed ring 125 to prevent splashed liquid from entering the support ring 109.

[0058] The feeding assembly 103 also includes a retaining ring 136, which is annular in shape and fixedly installed on the outer side of the gear ring 125 (i.e., the side away from the center of the conical baffle 108), forming a physical barrier between it and the support ring 109. During actual operation, especially when adding solvents (such as deionized water, ethanol, or other liquid matrices) into the dispersion tank, the liquid may splash due to impact or initial eddy currents during stirring. If splashed droplets enter the support ring 109, they may not only contaminate transmission components such as the gear 124 and gear ring 125, leading to lubrication failure, corrosion, or jamming, but may also cause carbomer powder to prematurely wet and clump in the transmission gap, affecting the normal operation of the equipment. The retaining ring 136, through its flange or labyrinth structure, effectively prevents liquid from radially or axially intruding into the support ring 109 area, while not hindering the normal rotation of the gear ring 125, thereby ensuring the cleanliness and dryness of the transmission system and improving the reliability and service life of the equipment.

[0059] The dispersion component 104 also includes a conical ring 137, which is disposed on the top of the support cylinder 111.

[0060] The dispersion component 104 further includes a conical ring 137, which is fixedly disposed at the top opening of the support cylinder 111, with its large end facing upward and its small end facing downward, forming an inverted cone or trumpet shape. The main function of the conical ring 137 is to guide the carbomer powder falling from the upper conical baffle 108 smoothly into the outside of the screw 112 channel, preventing the material from accumulating, bridging, or flowing off course at the inlet of the support cylinder 111.

[0061] The stirring assembly 105 also includes a guide vane 138, which is fixed above the support ring 109 and located on one side of the conical ring 137.

[0062] The stirring assembly 105 is further equipped with guide vanes 138, which are fixedly connected to the upper part of the support ring 109 (i.e., the side near the top of the dispersion shell 102) and arranged around the outer periphery or directly below the conical ring 137. The guide vanes 138 typically employ an arc-shaped, airfoil-shaped, or inclined flat plate structure, and their installation angle is optimized for hydrodynamics, enabling the formation of a directional axial or helical flow field in the upper region of the tank when the stirring motor 113 drives the support ring 109 to rotate. This design has multiple functions: firstly, it can re-entrain incompletely wetted carbomer particles overflowing from the periphery of the conical ring 137 into the main stirring zone, preventing them from remaining on the liquid surface or in dead corners of the tank wall; secondly, it can promote the initial mixing of liquid and powder before entering the main stirring zone, shortening the overall dispersion time.

[0063] Second Embodiment Please see Figure 7 The present invention also provides a carbomer dispersion method for preventing clumping, comprising: S201 The carbomer is placed into the hopper 106 and the discharge valve 107 is opened, so that the carbomer is dispersed into an annular flow along the conical baffle 108; Before the dispersion operation begins, dry carbomer powder is quantitatively added into the feed hopper 106. The control system is activated, and the electromagnetic control structure 119 is energized to open the discharge valve 107. Carbomer flows out of the feed hopper 106 through the discharge valve 107 under gravity. Since the discharge port faces the conical baffle 108 below, the powder is forced to slide evenly along the inclined conical surface after contacting the baffle surface, forming a continuous and stable annular powder flow (i.e., "annular downflow") under the combined action of centrifugal effect and the baffle geometry. This annular distribution significantly increases the contact area between the carbomer and the subsequent liquid medium, avoiding excessively high local concentrations or agglomeration caused by concentrated falling. During this process, the scraper structure 110 is simultaneously activated, periodically scraping the surface of the conical baffle 108, supplemented by heating and negative pressure recovery to ensure that the discharge channel remains unobstructed and residue-free.

[0064] S202 starts the stirring motor 113 to drive the screw 112 to rotate, so that the screw 112 pushes the liquid medium in the support cylinder 111 to rise, and mixes with the annular downward flow of carbomer before being discharged to both sides; Simultaneously with or slightly before the carbomer begins to be fed, the stirring motor 113 is started. The motor output shaft drives the screw 112, located inside the support cylinder 111, to rotate at high speed, and simultaneously drives the external stirring blades 115 to rotate synchronously. The screw 112 adopts a forward spiral structure, pushing the pre-placed liquid medium (such as deionized water, buffer solution, etc.) from the bottom of the tank upwards during rotation, forming a stable upward liquid flow. This upward liquid flow precisely meets the annular carbomer powder flow falling from the conical baffle 108 at the top of the support cylinder 111, achieving an ideal "liquid-encapsulated powder" wetting state. Subsequently, the mixed slurry, guided by the top of the screw 112 and the conical ring 137, is evenly distributed to both sides of the support cylinder 111 and enters the main stirring area. This stage completes the primary wetting, shearing, and initial dispersion of the carbomer, a crucial step in preventing agglomeration.

[0065] S203 stirring motor 113 drives stirring blade 115 to rotate for further mixing of carbomer and liquid medium.

[0066] After initial dispersion, the stirring blades 115, driven by the stirring motor 113, rotate continuously at high speed, creating a strong three-dimensional turbulent field within the dispersion shell 102. The stirring blades 115 are typically arranged in multiple layers or at multiple angles, working in conjunction with the upper guide vanes 138 to construct a composite flow pattern of vertical circulation and radial diffusion within the tank. This allows the initially wetted carbomer particles to fully deagglomerate, swell, and uniformly distribute throughout the liquid phase system under shear, tensile, and collision forces. This process continues for a certain time (typically 10–30 minutes, depending on the formulation and concentration) until a transparent or translucent, particle-free, viscosity-stable homogeneous gel is obtained. Throughout the stirring process, the system can monitor temperature, viscosity, or torque in real time, enabling intelligent feedback control to ensure consistent dispersion quality.

[0067] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
