Description

Technical Field

[0001] This invention belongs to the field of high-speed disperser technology, specifically a closed high-speed disperser for environmentally friendly coating production. Background Technology

[0002] Environmentally friendly coatings refer to coating products that meet the technical requirements of national environmental labeling products and have characteristics such as low volatile organic compound content and non-toxicity. They are mainly used in the field of building decoration and are classified into low VOC, zero VOC and health-functional types.

[0003] In the coating production process, the dispersion process is a key step to fully mix pigments, fillers and base materials, and its effect directly affects the quality of the final product. Traditional dispersion equipment is mostly open-type high-speed dispersers, which use the high-speed rotation of the stirring impeller to shear and disperse the materials. However, when processing coatings containing organic solvents, the open structure is prone to causing a large amount of volatile organic compounds to escape, which not only pollutes the environment but also poses safety hazards. In addition, the materials are easily contaminated by external impurities.

[0004] Traditional coating dispersion equipment is mostly open-type. During high-speed mixing, air is easily mixed into the material, generating bubbles and affecting product quality. At the same time, the large-scale volatilization of organic solvents not only causes material loss but also brings serious environmental pollution and safety risks, making it difficult to meet increasingly stringent environmental regulations. Therefore, the industry has gradually developed closed-type dispersion devices. However, existing closed-type dispersion devices still have the following shortcomings in practical applications: 1. Most closed dispersers rely solely on the single-axis rotation of the impeller to generate shear force, causing the material to form laminar flow or local vortex within the drum. This makes it difficult to achieve overall macro-mixing, and the powder tends to settle at the bottom of the drum or in dead corners, resulting in uneven material dispersion within batches and affecting product consistency. 2. During the dispersion process, coatings often adhere to the cylinder wall due to centrifugal force or electrostatic adsorption. This is especially true in high-viscosity formulations, where material accumulation on the cylinder wall is severe. Traditional equipment lacks an effective online cleaning mechanism, and the residual material not only causes waste but also increases the difficulty of color change or shutdown for cleaning.

[0005] 3. To achieve power input under closed conditions, existing equipment mostly uses mechanical seals or packing seals. However, the long-term high-speed rotation of the main shaft can easily lead to wear and leakage of the seals, requiring frequent maintenance. In order to take into account both stirring and cylinder tilting functions, some devices use multiple motors for independent drive, which not only makes control complex but also makes it difficult to ensure phase synchronization between various moving parts, affecting the stability of the dispersion process. Summary of the Invention

[0006] The purpose of this invention is to: control the overall rotation of the tilting frame by a drive motor, while the rotation mechanism independently drives the dispersion drum and the agitator blades to rotate. The material inside the drum is not only sheared and dispersed by the agitator blades, but also its gravity accumulation position continuously changes as the drum rotates, effectively preventing material deposition and ensuring the uniformity of the batch. The use of a wall scraping mechanism achieves efficient self-cleaning. The lifting motor drives the side wall scraper ring to move up and down along the limit rod via magnetic coupling, scraping away accumulated material on the drum wall. Forced wall scraping can completely scrape off the coating adhering to the drum wall and participate in the discharge, significantly reducing residue and waste. A fixed bevel gear ring meshes with the drum drive bevel gear and the agitator drive bevel gear respectively, stably obtaining power during the tilting process. When the tilting frame rotates, the mechanical energy of the tilting is converted into a power source to drive the internal components to rotate, achieving complex motion control in a completely closed drum state. This makes the combined motion of revolution and rotation more reliable, ensuring a stable phase relationship between the agitator blades and the drum rotation, and improving the repeatability of the dispersion process.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Example 1, refer to Figure 1-8 A closed-loop high-speed dispersion device for producing environmentally friendly coatings, comprising: Base 1; A flipping mechanism is provided on the base 1. The flipping mechanism includes a drive motor 9 and a flipping frame 10. The flipping frame 10 is rotatably connected to the base 1, and the drive motor 9 is fixedly connected to the base 1. The output end of the drive motor 9 is fixedly connected to one end of the flipping frame 10. The dispersing drum 22 has two ends that are rotatably connected to the tilting frame 10. The stirring blade 20 is rotatably connected to the dispersing drum 22; The rotating mechanism is mounted on the tilting frame 10 and is rotatably connected to the base 1. The rotating mechanism is also connected to the dispersing drum 22 and the stirring blade 20. The wall scraping mechanism is located inside the dispersing drum 22. The wall scraping mechanism includes an adjustment component, a bottom scraper 23, and a side wall scraper ring 17. The adjustment component is located inside the dispersing drum 22. The side wall scraper ring 17 is movably connected inside the dispersing drum 22 and is connected to the adjustment component. There are two bottom scrapers 23, which are fixedly connected to the upper and lower ends of the stirring blade 20, respectively.

[0024] In this implementation scheme: the model of the drive motor 9 can be selected from commercially available models as needed, and will not be elaborated on here. The drive motor 9 controls the rotation of the tilting frame 10, causing the internal dispersing drum 22 and agitator blade 20 to rotate accordingly. The rotation mechanism also controls the independent rotation of the dispersing drum 22 and agitator blade 20. While the dispersing drum 22 revolves around the tilting frame 10, the dispersing drum 22 and agitator blade 20 rotate on their own axes. This causes the material inside the dispersing drum 22 to not only be sheared and dispersed by the agitator blade 20, but also to continuously change its gravity accumulation position as the dispersing drum 22 rotates as a whole. This composite motion has… This effectively prevents powder from depositing at the bottom or corners of the dispersing drum 22, ensuring the macroscopic uniformity of all materials within a batch. The bottom scraper 23 and the side wall scraper ring 17 work together to scrape the inner wall of the dispersing drum 22, preventing the coating from sticking to the wall. The side wall scraper ring 17 is driven by the magnetic ring 16 in the air, avoiding the need for complex dynamic sealing structures on the wall of the dispersing drum 22, reducing potential leakage points, simplifying the mechanical structure, making the equipment more stable and reliable in long-term operation, and reducing maintenance costs. The forced scraping of the side wall scraper ring 17 can completely scrape off the coating adhering to the wall of the dispersing drum 22 to participate in mixing or discharge, significantly reducing residue and waste.

The agitation synchronization chain 12 is sleeved on the agitation drive sprocket 13 and the agitation driven sprocket 14, and the agitation synchronization chain 12 meshes with the agitation drive sprocket 13 and the agitation driven sprocket 14.

[0034] In this embodiment, the stirring synchronization chain 12 and the stirring drive sprocket 13 are the same size.

The adjustment magnetic ring 16 is slidably connected inside the lifting cavity 21. Multiple lifting assemblies are provided, and all multiple lifting assemblies are located inside the lifting cavity 21 and are connected to the adjustment magnetic ring 16.

[0036] In this embodiment: the adjusting magnetic ring 16 is connected to the side wall scraping ring 17. Through mutual magnetic attraction, the adjusting magnetic ring 16 drives the side wall scraping ring 17 to rise and fall during the lifting and lowering process in the lifting cavity 21, thus completing the scraping.

[0037] Specifically: Each lifting assembly includes a lifting motor 15 and a lifting screw 18. The lifting motor 15 is fixedly connected inside the dispersing drum 22, and the lifting screw 18 is rotatably connected inside the lifting chamber 21.

[0038] In this embodiment, the model of the lifting motor 15 can be selected from those available on the market as needed, which will not be elaborated here. The lifting motor 15 controls the lifting screw 18 to rotate, thereby realizing the lifting and lowering of the adjusting magnetic ring 16. The lifting motor 15 drives the side wall scraping ring 17 to move up and down along the limiting rod 19 through magnetic coupling, scraping off the material accumulated on the wall of the dispersing drum 22.

[0042] In this embodiment: when the tilting frame 10 rotates, the rotating drum drive bevel gear 6 and the agitation drive bevel gear 8 mesh and roll along the fixed bevel gear ring 7, thereby converting the mechanical energy of the tilting into a power source to drive the internal components to rotate, realizing complex motion control in the completely closed state of the cylinder. Compared with the electric control multi-motor drive, the mechanical gear transmission is more reliable in realizing the compound motion of revolution and rotation. The discharge valve 24 and the inlet valve 25 are existing technologies and will not be described in detail here. The raw materials and finished products are controlled by the discharge valve 24 and the inlet valve 25 to complete the use.

[0043] During use, ensure that the bottom discharge valve 24 is closed and the top inlet valve 25 is ready to open. Open the inlet valve 25 and inject the pre-mixed raw materials into the dispersing drum 22. After injection, close the inlet valve 25 to ensure the drum is completely sealed. Turn on the drive motor 9 to drive the tilting frame 10 to slowly tilt, causing the material inside the dispersing drum 22 to continuously change its accumulation position under gravity, preventing powder from accumulating in dead corners. As the tilting frame 10 rotates, the drum drive bevel gear 6 and the agitation drive bevel gear 8 mesh and roll along the fixed bevel gear ring 7 to obtain rotational power. The power is transmitted through the drum drive rod 5, the drum driven sprocket 2, the drum synchronous chain 3, and the rotating drum. The drive sprocket 4 transmits power to the dispersing drum 22. Simultaneously, power is transmitted to the agitator blade 20 via the agitation transmission rod 11, agitation synchronization chain 12, agitation drive sprocket 13, and agitation driven sprocket 14, achieving dispersion. After dispersion, the discharge valve 24 is positioned at the bottom and connected to the external output pipe to output the finished material. After output, the drive motor 9 controls the overall micro-rotation, causing the bottom scraper 23 to scrape the material from the top and bottom. When finished, the lifting motor 15 controls the lifting screw 18 to rotate, driving the adjusting magnetic ring 16 to move up and down in the lifting chamber 21. Through magnetic force, the side wall scraper ring 17 moves up and down synchronously with the adjusting magnetic ring 16, scraping off the accumulated material on the drum wall to achieve discharge.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
