Description

Technical Field

[0001] This invention relates to the field of textile auxiliary production technology, and specifically to a textile auxiliary compounding equipment. Background Technology

[0002] In the textile industry, textile auxiliaries are key materials for improving textile quality, enhancing processing techniques, and endowing textiles with special functions. Their compounding effect directly determines the quality of subsequent dyeing, finishing, and other processes. The compounding of textile auxiliaries involves mixing, dispersing, and degassing multiple functional components in specific proportions to form a uniform and stable system. High viscosity is a typical characteristic of most textile auxiliaries, such as leveling agents, fixing agents, and finishing agents, making their compounding process a technical challenge in the industry.

[0003] Chinese patent document CN117548061B discloses a mixing vessel for mixing textile auxiliaries, comprising a mixing vessel body and a support frame. The mixing vessel body is installed inside the support frame, with a top cover on the top of the mixing vessel body and a discharge pipe installed at the bottom. A stirring mechanism is located at the bottom of the top cover, and a driving mechanism is located at one end of the support frame. The inner bottom surface of the mixing vessel body is equipped with a dispersing mechanism for assisting in dispersing the sedimented raw materials at the bottom. In use, multiple dispersing rods of the dispersing mechanism move back and forth repeatedly on the top of the circular plate, enabling the multiple dispersing rods to disperse the sedimented and clumped raw materials at the bottom of the mixing vessel body, facilitating more uniform mixing of various raw materials.

[0004] While the aforementioned devices can mix various raw materials for textile auxiliaries, they still have shortcomings. During the material mixing stage, high-viscosity fluids have poor flowability and easily adhere to the inner wall of the equipment, forming a wall-mounted layer. This not only causes raw material loss and increases production costs but also reduces the heat transfer efficiency of the equipment's inner wall, affecting the uniformity of subsequent material mixing. In the degassing stage, traditional equipment often uses natural degassing or simple vacuum degassing methods, which are insufficient to remove fine air bubbles from high-viscosity materials. These residual microbubbles can form pinholes, spots, and other defects during textile processing, reducing product qualification rates. Summary of the Invention

[0005] This invention provides a textile auxiliary compounding device, which aims to solve the problems of high-viscosity material wall-adhering loss, uneven mixing and dispersion, and microbubble residue in related textile auxiliary compounding devices.

[0006] The present invention provides a textile auxiliary compounding device, which includes a kettle body, and further includes a coaxial drive assembly, a material dispensing assembly and a wall scraping assembly disposed inside the kettle body.

[0007] The coaxial drive assembly includes an independently driven central shaft and a hollow shaft. The lower end of the central shaft is fixedly connected to a stirring component, and the hollow shaft is sleeved outside the central shaft and fixedly connected to a stirring frame.

[0008] The material distribution assembly includes a centrifugal material distribution plate, which is fixedly connected to the top of the stirring frame and rotates with it, and is used to centrifugally throw the material carried on the material distribution plate onto the inner wall of the vessel.

[0009] The wall scraping assembly includes a connecting seat, a scraper, and a cleaning scraper. The connecting seat is connected to the side of the mixing frame, and the scraper is rotatably connected to the connecting seat. It is used to flatten the material thrown out by the distribution plate on the inner wall of the vessel to form a liquid film. The cleaning scraper is fixedly installed on the connecting seat and extends axially along the inner wall of the vessel. It is used to scrape off the material on the inner wall of the vessel. The scraper and the cleaning scraper are staggered in the rotational circumference of the mixing frame to form a circumferential gap between them for releasing air bubbles from the liquid film.

[0010] Its effects are as follows: Through the coordinated operation of the coaxial drive assembly, the dispensing assembly, and the wall scraping assembly, it overcomes the problems of uneven mixing, wall-attachment loss, and microbubble residue in existing technologies for high-viscosity materials, achieving a highly efficient, uniform, and low-bubble compounding process, significantly improving product quality and production efficiency. Specifically, the independently driven central shaft and hollow shaft provide differentiated power to the stirring components and stirring frame, achieving macroscopic uniform mixing and microscopic deep dispersion of materials; the dispensing disc uses centrifugal force to form a thin film of material on the inner wall of the vessel, laying the foundation for efficient degassing; the scraper rotates with the stirring frame, effectively flattening the liquid film and promoting bubble overflow; the cleaning scraper extends along the axial direction of the vessel body, ensuring thorough cleaning of the inner wall and preventing wall adhesion. Furthermore, the staggered arrangement of the scraper and cleaning scraper in the circumferential direction creates a bubble release gap, solving the problem of bubbles in high-viscosity materials failing to rise quickly, effectively improving degassing efficiency.

[0011] Preferably, a radial guide block is provided on the circumferential edge of the distribution plate. The radial guide block is correspondingly provided with the scraper assembly to intercept the material thrown out by the distribution plate, so as to prevent the material from directly entering the gap between the scraper and the cleaning scraper.

[0012] Its effect is that by setting radial guide baffles at the edge of the distribution plate, the trajectory of the material can be precisely controlled, avoiding the material from splashing directly into the gap between the scraper and the cleaning scraper, and ensuring that the material can be stably pre-attached to the designated area on the inner wall of the vessel.

[0013] Preferably, an adjustable rod is provided between the stirring frame and the wall scraping assembly. One end of the adjustable rod is fixedly connected to the stirring frame, and the other end is linked to the connecting seat. By adjusting the extension and retraction length of the adjustable rod, the initial radial position of the wall scraping assembly relative to the hollow shaft can be changed.

[0014] Its effect is that by setting an adjustable rod, the initial radial distance between the scraping component and the inner wall of the vessel can be adjusted according to different vessel sizes, solving the problems of equipment versatility and installation accuracy, and improving the equipment's adaptability and ease of installation.

[0015] Preferably, an elastic telescopic rod is provided between the adjusting rod and the connecting seat, and a compression spring is provided inside the elastic telescopic rod. One end of the compression spring abuts against the adjusting rod, and the other end abuts against the connecting seat, which is used to provide radial preload force for the cleaning scraper to fit tightly against the inner wall of the vessel.

[0016] Its effect is that by setting up an elastic telescopic rod and its internal compression spring, it can continuously and stably provide radial preload, ensuring that the scraper and cleaning scraper are always in close contact with the inner wall of the vessel, effectively dealing with dynamic factors such as changes in material viscosity and thermal expansion of the vessel during the stirring process, ensuring the flattening efficiency of the scraper and the thoroughness of the cleaning scraper, and significantly improving the wall scraping effect.

[0017] Preferably, the scraper is rotatably connected to the connecting seat via a rotating shaft. A torsion spring that provides a reset torque is provided on the rotating shaft. A limit rod is provided on the connecting seat, and a limit pin is provided on the rotating shaft. The limit pin and the limit rod cooperate to limit the rotation angle of the scraper.

[0018] Its effect is that by setting torsion springs and rotation limit structures, when the scraper encounters hard scale or foreign objects on the vessel wall, the rotating shaft can automatically unload the impact force, avoid damage to the scraper itself, greatly improve the operational reliability and safety of the scraper assembly, and effectively extend its service life.

[0019] Preferably, a circulating conveying pipe is connected to the outside of the vessel body. One end of the circulating conveying pipe is connected to the discharge port at the bottom of the vessel body, and the other end extends to the top of the vessel body and faces the distribution plate. A material pump is installed on the circulating conveying pipe to transport the material at the bottom of the vessel body to the distribution plate.

[0020] Its effect is that by setting up a circulating conveying pipe and a material pump, continuous closed-loop circulation of materials in the reactor can be achieved, ensuring that all materials at the bottom of the reactor can be continuously transported to the distribution plate for film treatment and degassing, thereby ensuring the thoroughness, uniformity and efficiency of material treatment in the entire reactor.

[0021] Preferably, the surface of the material distribution disc is a conical umbrella-shaped structure that slopes downward from the center to the edge, and the circumferential edge of the material distribution disc is provided with serrated material dispensing teeth along the circumferential direction.

[0022] Its effects are as follows: the conical structure helps the material to spread evenly, while the serrated dispersing teeth can disperse the material more finely and throw it out, forming a film with better quality and more uniform thickness that adheres to the inner wall of the vessel, increasing the contact area between the material and the air, and creating favorable conditions for subsequent efficient degassing.

[0023] Preferably, the blade of the scraper is arc-shaped or inclined away from the inner wall of the vessel, so as to form a gradually narrowing wedge-shaped pressing area between the scraper and the inner wall of the vessel.

[0024] Its effect is that by forming a gradually narrowing wedge-shaped pressing zone between the scraper and the inner wall of the vessel, when the scraper moves, this zone can exert a continuous squeezing effect on the bubbles in the material, causing their volume to decrease until they burst, thereby more thoroughly expelling the bubbles from the liquid film.

[0025] Preferably, the blade of the cleaning scraper is straight or has a sharp cut that is inclined toward the rotation direction of the inner wall of the vessel, so as to fit tightly with the inner wall of the vessel for mechanical peeling.

[0026] Its effects are as follows: the straight or sharp cut surface of the cleaning scraper ensures thorough scraping, effectively removes attached liquid film, wall-sticking substances or scale, prevents dead corners and material residue, and maintains the cleanliness of the inner wall of the vessel.

[0027] Preferably, the central shaft and the hollow shaft are configured to be driven independently and rotate at different speeds, with the rotational speed of the central shaft being higher than that of the hollow shaft.

[0028] Its effect is that the differentiated power output of the central shaft and the hollow shaft can ensure the uniformity of mixing of high-viscosity materials at different scales, significantly improve the mixing and dispersion efficiency, reduce the dead zone of mixing, and thus ensure the quality and performance stability of textile auxiliaries.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. This invention uses the rotation of the stirring rack to centrifuge the material carried on the dispensing plate to form a liquid film that adheres to the inner wall of the reactor, increasing the gas-liquid contact area. Then, the liquid film is flattened by a scraper to promote the overflow of bubbles. At the same time, the circumferentially staggered gap between the scraper and the cleaning scraper provides additional time for residual bubbles to escape, which can effectively remove microbubbles in high-viscosity materials, avoid defects on the surface of textiles, and improve the product qualification rate.

[0031] 2. By setting up cleaning scrapers, the present invention can thoroughly scrape off the material on the inner wall of the reactor, avoid material adhesion and residue, reduce raw material loss, maintain the cleanliness of the inner wall of the reactor, provide a smooth working surface for efficient degassing, and ensure heat transfer efficiency and process stability.

[0032] 3. The present invention is equipped with a dual-axis concentric differential speed drive assembly. The high-speed rotation of the central shaft drives the stirring component to achieve microscopic high-shear dispersion of materials, while the low-speed rotation of the hollow shaft drives the stirring frame to achieve macroscopic mixing. The two work together to effectively solve problems such as uneven mixing, agglomeration and stratification of high-viscosity materials, ensuring that the effective components of the additives play a full role and improving the effect of subsequent textile processing.

[0033] 4. The wall scraping assembly of the present invention adopts an adjustable structure and elastic protection design, which can adjust the gap between the wall scraping assembly and the inner wall of the vessel through the adjustment rod to adapt to different vessel sizes and material viscosities; it can provide pre-tightening force for the cleaning scraper through the elastic telescopic rod to ensure close contact with the inner wall and automatically compensate for wear; the torsion spring and rotation limit structure of the scraper can automatically unload and avoid obstacles when encountering resistance, and reset after being subjected to force, which greatly improves the adaptability and reliability of the equipment and reduces the equipment maintenance cost.

[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. 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.

[0046] like Figures 1 to 9 As shown, a textile auxiliary compounding device of the present invention includes a kettle body 11, a coaxial drive assembly, a material dispensing assembly, and a wall scraping assembly.

[0047] like Figures 1 to 3 As shown, the vessel body 11, as the core container for the compounding of textile auxiliaries, is made of corrosion-resistant, high-temperature-resistant, and high-strength stainless steel. This ensures that the vessel body 11 can withstand the corrosion of various chemical components in the textile auxiliaries while meeting the temperature control requirements during the compounding process. Preferably, the vessel body 11 is designed as a double-layer jacketed structure, comprising an inner vessel wall and an outer vessel wall. The inner vessel wall holds the textile auxiliaries to be compounded, and a jacket gap is formed between the outer and inner vessel walls. A spiral heating tube 13 is installed within this jacket gap, forming a heating assembly. The vessel body 11 is typically cylindrical, with an inlet at the top for adding the various textile auxiliary components to be compounded. An outlet at the bottom of the vessel body 11 discharges the compounded textile auxiliaries. A valve is installed at the outlet to control the discharge speed and quantity. The inner wall of the vessel body 11 undergoes high-precision polishing to reduce material adhesion and provide a smooth working surface for the scraping assembly.

[0048] like Figures 1 to 3 As shown, a circulating conveying pipe 12 is externally connected to the vessel body 11 to achieve closed-loop circulation of materials within the vessel body 11, ensuring that all materials within the vessel can continuously participate in the mixing, dispersion, and degassing processes, thereby improving the uniformity of the compounding. Specifically, one end of the circulating conveying pipe 12 is connected to the discharge port at the bottom of the vessel body 11, and a sealing gasket is provided at the connection to ensure sealing performance and prevent material leakage. The other end of the circulating conveying pipe 12 extends upward to the top of the vessel body 11, and then bends downward so that its outlet faces the distributing component, ensuring that the circulating material can accurately fall into the distributing tray 3, avoiding material splashing. The circulating conveying pipe 12 is equipped with a material pump suitable for conveying high-viscosity materials. The material pump can be a screw pump, which has the characteristics of high conveying pressure, stable flow rate, and the ability to convey high-viscosity materials, adapting to the conveying needs of high-viscosity textile auxiliaries.

[0049] like Figures 3 to 6As shown, the coaxial drive assembly is located inside the vessel body 11 and is the core power component for material mixing and dispersion. Specifically, it includes a central shaft 21, a hollow shaft 22, a first drive motor 25, and a second drive motor (not shown in the figure). Both the central shaft 21 and the hollow shaft 22 are coaxially arranged with the vessel body 11. The hollow shaft 22 is sleeved outside the central shaft 21, and a bearing is installed between them to ensure that the central shaft 21 and the hollow shaft 22 can rotate independently without interference. The bearing is a high-temperature resistant and corrosion-resistant rolling bearing with a sealing structure to prevent material from the vessel body 11 from entering the bearing and affecting its service life and rotational accuracy.

[0050] like Figures 3 to 6 As shown, the central shaft 21 is made of high-strength stainless steel and is a solid cylinder. The top end of the central shaft 21 passes through the sealed end cap at the top of the vessel body 11, extends to the outside of the vessel body 11, and is connected to a drive motor 25. The drive motor 25 is fixedly mounted on a bracket at the top of the vessel body 11 and is connected to the central shaft 21 via a coupling to drive the central shaft 21 to rotate. The lower end of the central shaft 21 extends to the bottom of the vessel body 11, and a stirring component 23 is fixedly connected to its end. The stirring component 23 is a high-shear stirring paddle, including blades and a paddle base. The paddle base is fixedly connected to the central shaft 21 via a key, ensuring that the stirring component 23 can rotate synchronously with the central shaft 21. The blades are designed with an inclined shape, which can generate a strong shearing effect on the material at the bottom of the vessel body 11 during high-speed rotation, achieving microscopic high-shear dispersion of the material and ensuring uniform dispersion of the effective components of the additives.

[0051] like Figures 3 to 6 As shown, the hollow shaft 22 is made of high-strength stainless steel and is in the shape of a hollow cylinder. The second drive motor is fixedly mounted on a bracket at the top of the vessel body 11. The output end of the second drive motor is linked to the hollow shaft 22 via a synchronous belt drive, enabling the rotation of the hollow shaft 22. A stirring rack 24 is fixedly connected to the outside of the hollow shaft 22. The stirring rack 24 is made of stainless steel, and its overall size is adapted to the internal space of the vessel body 11, ensuring that the stirring rack 24 can cover most of the interior area of ​​the vessel body 11 during rotation, achieving macroscopic mixing of the materials.

[0052] In this embodiment, the central shaft 21 and the hollow shaft 22 are configured to be independently driven and rotate at different speeds, with the rotational speed of the central shaft 21 being higher than that of the hollow shaft 22. This independent differential drive can create a strong shear gradient within the material, further promoting the uniformity of material mixing. Preferably, the two can be configured to rotate in the same direction or in opposite directions. When rotating in opposite directions at different speeds, stronger shear force and stirring effect can be generated, further improving the uniformity of mixing and dispersion. When rotating in the same direction at different speeds, material disturbance can be reduced, avoiding the generation of excessive bubbles, which is suitable for compounding processes with high requirements for bubble control.

[0053] like Figures 2 to 5 As shown, the material distribution component is located inside the vessel body 11 and is fixedly installed on top of the stirring frame 24, rotating synchronously with the stirring frame 24. The material distribution component mainly includes a centrifugal distribution plate 3. Through the rotation of the stirring frame 24, the material carried on the distribution plate 3 can be thrown onto the inner wall of the vessel body 11 by centrifugal force, forming a thin film, which lays the foundation for the subsequent degassing process. The distribution plate 3 is made of stainless steel and has an overall conical umbrella-shaped structure that slopes downward from the center to the edge. This conical structure facilitates the radial flow of material along the conical surface under the action of centrifugal force, preventing material from accumulating on the surface of the distribution plate 3.

[0054] like Figures 3 to 7 As shown, the wall scraping assembly is installed on the outer periphery of the stirring rack 24 and is evenly distributed along the circumference of the vessel body 11. The wall scraping assembly mainly includes a connecting seat 41, a scraper 42, a cleaning scraper 43, an adjusting rod 44, and an elastic telescopic rod 45. The connecting seat 41 is made of stainless steel and has a block structure. It is responsible for bearing the scraper 42 and the cleaning scraper 43 and is linked with the adjusting rod 44. The scraper 42 has a long strip structure and is located in the upper part inside the vessel body 11. It is rotatably connected to the connecting seat 41 through a rotating shaft 421. It is mainly used to force the new material thrown out by the distribution plate 3 onto the inner wall of the vessel body 11 when the wall scraping assembly rotates, forming a uniform and extremely thin liquid film. The blade of the scraper 42 is preferably arc-shaped or inclined away from the inner wall of the vessel body 11 to form a gradually narrowing wedge-shaped pressing area between the scraper 42 and the inner wall of the vessel body 11. The wedge-shaped pressing area applies pressure to the liquid film to maximize the overflow of air bubbles in the liquid film. The cleaning scraper 43 is fixedly installed on the connecting seat 41 and extends axially along the inner wall of the vessel body 11. Its length preferably covers most of the side wall of the vessel body 11. It is mainly used to scrape off the liquid film that has been flattened and defoamed by the scraper 42 on the inner wall of the vessel body 11, as well as any old materials or adhering substances that may remain, ensuring that the inner wall of the vessel body 11 is always kept clean. The blade of the cleaning scraper 43 is preferably straight or has a sharp cut that is inclined towards the rotation direction of the inner wall of the vessel body 11, so as to fit tightly against the inner wall of the vessel body 11 for mechanical peeling.

[0055] In this design, the scraper 42 and the cleaning scraper 43 are staggered circumferentially in the rotational direction of the mixing frame 24 to form a circumferential gap between them for the release of air bubbles from the liquid film. This staggered design allows the material to first be flattened and degassed by the scraper 42, and then enter the circumferential gap area between the scraper 42 and the cleaning scraper 43. Within this gap area, residual air bubbles in the liquid film have additional time to rise and escape, further improving the degassing efficiency. Afterwards, the cleaning scraper 43 thoroughly scrapes away the degassed liquid film.

[0056] like Figures 3 to 7As shown, the adjusting rod 44 is positioned between the stirring frame 24 and the connecting seat 41. One end is fixedly connected to the side of the stirring frame 24, and the other end is linked to the connecting seat 41. The adjusting rod 44 has an adjustable length structure, which can be designed as a threaded telescopic structure or a sleeve-type telescopic structure. By adjusting the telescopic length of the adjusting rod 44, the initial radial position of the entire scraping assembly relative to the hollow shaft 22 can be changed, allowing the equipment to adapt to vessel bodies 11 with different inner diameters.

[0057] like Figures 3 to 7 As shown, the elastic telescopic rod 45 is positioned between the adjusting rod 44 and the connecting seat 41. A compression spring is installed inside the elastic telescopic rod 45, with one end of the spring abutting against the adjusting rod 44 and the other end abutting against the connecting seat 41. Due to the elastic telescopic characteristics of the compression spring, it provides a continuous and stable radial preload to the scraper 42 and the cleaning scraper 43, ensuring they fit tightly against the inner wall of the vessel 11 in real time. This addresses gap changes caused by variations in material viscosity, thermal expansion of the vessel 11, or minor deformation during stirring, thus maintaining the efficiency of wall scraping and degassing. Simultaneously, the elastic preload also buffers vibrations generated during the rotation of the wall scraping assembly, reducing equipment wear and extending its service life.

[0058] Furthermore, such as Figures 4 to 9 As shown, a torsion spring 46 and a rotation limiting structure are provided between the scraper 42 and the connecting seat 41. The torsion spring 46 is sleeved on the rotating shaft 421, with one end fixed to the connecting seat 41 and the other end fixed to the scraper 42. It is used to provide a reset torque so that the scraper 42 maintains a specific tilt angle during normal operation, ensuring that the scraper 42 can effectively flatten the material. The rotation limiting structure includes a limiting rod 411 provided on the connecting seat 41 and a limiting pin 422 provided on the rotating shaft 421. Through the cooperation of the limiting rod 411 and the limiting pin 422, the rotation angle of the scraper 42 can be limited. When the scraper 42 encounters hard scale or foreign objects on the vessel wall, it can rotate around the shaft 421. Under the limiting action of the limiting rod 411, the limiting pin 422 will not exceed the maximum rotation angle, thus avoiding damage caused by excessive rotation of the scraper 42. When the force is released, under the action of the reset torque of the torsion spring 46, the scraper 42 automatically returns to the initial working angle, which greatly improves the reliability and safety of the equipment.

[0059] like Figures 3 to 5As shown, radial flow guide blocks 31 are provided on the circumferential edge of the distribution plate 3. The radial flow guide blocks 31 are correspondingly arranged with the wall scraping components, that is, the number of radial flow guide blocks 31 is the same as the number of wall scraping components, and each wall scraping component corresponds to one radial flow guide block 31. The radial flow guide blocks 31 are made of stainless steel and have an arc-shaped structure. They are fixedly installed on the edge of the distribution plate 3 and can effectively intercept the material thrown out by the distribution plate 3, guide the material to adhere smoothly to the front area of ​​the scraper 42 on the inner wall of the vessel body 11, prevent the material from directly entering the circumferential gap between the scraper 42 and the cleaning scraper 43, thereby ensuring that the material can be flattened and defoamed by the scraper 42 first, and avoid the undefoamed material being directly scraped off by the cleaning scraper 43, thus improving the defoaming effect.

[0060] like Figures 3 to 5 As shown, the circumferential edge of the distribution plate 3 is uniformly provided with serrated material dispersing teeth 32. The tips of the material dispersing teeth 32 are sharp, which can evenly divide the material on the distribution plate 3, ensuring that the material can be evenly thrown out under the action of centrifugal force, avoiding the phenomenon of material agglomeration and throwing out, and thus forming a liquid film of uniform thickness on the inner wall of the vessel 11.

[0061] Based on the above-described device, the working process and working principle of the present invention are as follows:

[0062] First, the operator adds the various textile auxiliary components to be compounded into the reactor 11 through the feed inlet at the top of the reactor 11 according to the specified ratio. Then, the heating assembly is activated, and the spiral heating tube 13 heats the material in the reactor 11 until the material temperature reaches the set value, reducing the material viscosity and improving its flowability. Next, drive motors 25 and 2 are activated. Drive motor 25 drives the central shaft 21 to rotate at high speed, and the stirring component 23 at the lower end of the central shaft 21 continuously shears and disperses the material at the bottom of the reactor 11. Simultaneously, drive motor 2 drives the hollow shaft 22 to rotate at a lower speed, differentially with the central shaft 21. The hollow shaft 22 drives the stirring frame 24 to perform macroscopic mixing, promoting the overall flow of the material in the reactor 11 and preventing material stratification and clumping.

[0063] Next, the material pump is started and the valve on the circulating conveying pipe 12 is opened. The material pump continuously draws and transports the material at the bottom of the vessel 11 through the circulating conveying pipe 12 to the distribution plate 3 at the top of the vessel 11, forming a material circulation to ensure that all materials in the vessel can continuously participate in the mixing, dispersion and degassing process. After the material reaches the distribution plate 3, under the centrifugal force generated by the rotation of the distribution plate 3 with the stirring rack 24, it flows radially along the conical inclined surface of the distribution plate 3, and is evenly thrown out by the serrated dispersing teeth 32 at the edge of the distribution plate 3. At the same time, under the precise guidance of the radial guide baffle 31, it is stably attached in a thin film to the area in front of the scraper 42 on the inner wall of the vessel 11.

[0064] As the stirring rack 24 continues to rotate, the scraper 42 first rotates to the thin film. With the cooperation of the torsion spring 46 and the rotation limiting structure, the scraper 42 maintains a specific working angle, and its blades forcefully flatten the material, forming a uniformly thick and extremely thin liquid film. This promotes the rapid escape of bubbles from the liquid film, completing the initial degassing. Subsequently, the ultra-thin liquid film after initial degassing enters the circumferential gap area between the scraper 42 and the cleaning scraper 43. This gap area provides a brief transition and residence time for the liquid film, allowing residual bubbles that have not completely escaped from the viscous liquid film more time to float and escape, further improving the degassing efficiency. Next, the cleaning scraper 43 moves to this area, and its blade fits tightly against the inner wall of the vessel 11. Under the pre-tightening force of the elastic telescopic rod 45, it thoroughly scrapes away the liquid film that has undergone secondary degassing, ensuring the cleanliness of the inner wall of the vessel 11 and preventing material adhesion and scaling. At the same time, the scraped material is guided back to the bottom of the vessel 11, completing a complete cycle of "discharging - flattening - degassing - scraping - wall renewal".

[0065] Once the compounding process has reached the set time and the mixing, dispersion, and degassing effects of the materials have met the requirements, each component is shut off in sequence. After the materials have cooled to room temperature, the discharge valve is opened to discharge the compounded textile auxiliaries. Finally, the equipment is cleaned and maintained to prepare for the next compounding.
