Description

Technical Field

[0001] This utility model relates to the field of latex paint production technology, and in particular to a mixing tank for latex paint production. Background Technology

[0002] Latex paint is a water-based coating made from synthetic resin emulsion as a base, with added pigments, fillers and additives. It is environmentally friendly, non-toxic and quick-drying, and is widely used in interior wall decoration. In latex paint production, the mixing tank is a key piece of equipment used to fully mix various raw materials. However, traditional mixing tanks have problems such as chaotic feeding sequence, uneven mixing, difficulty in cleaning and residual pollution. To solve these problems, a new type of mixing tank for latex paint production has emerged.

[0003] A search revealed that the document with publication number "CN221062334U" mentions "This utility model discloses a mixing tank for latex paint production, belonging to the field of mixing tanks. It includes a mixing tank body, a top cover at the upper end of the mixing tank body, and a motor mounted on the top cover. Inside the mixing tank body is a rotating shaft connected to the motor, and a stirring structure is mounted on the rotating shaft. By setting an adjustable stirring structure, the relative position of the second mounting sleeve and the first mounting sleeve can be changed when needed, thereby changing the angle between the first stirring rod and the second stirring rod, and thus changing the shape of the entire stirring structure, resulting in a change in the stirring effect and improved adaptability. Setting stirring components on the first and second stirring rods can expand the stirring range, and when the angle between the first and second stirring rods changes, the stirring components only change in spatial position, not in shape." The adjustable stirring structure allows for changes in the relative positions of the second and first mounting sleeves, altering the angle between the first and second stirring rods and thus the overall shape of the stirring structure. This changes the stirring effect and improves adaptability. The stirring components are mounted on the first and second stirring rods, expanding the stirring range. Furthermore, when the angle between the first and second stirring rods changes, the stirring components only change spatially, not in shape, thus not affecting their performance. The simple structure and excellent performance are noteworthy. However, the stirring system of this device relies solely on a single central stirring shaft, leading to insufficient mixing of materials at the edges and bottom of the tank, potentially causing material accumulation and affecting product quality.

[0004] To address these issues, we provide a mixing tank for latex paint production. Utility Model Content

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] See Figure 1-4 A mixing tank for latex paint production includes a mixing tank body 1 and a dispersing and stirring assembly 4. The dispersing and stirring assembly 4 is installed on the upper end of the mixing tank body 1. The dispersing and stirring assembly 4 includes a stirring motor 401 installed on the upper end of the mixing tank body 1. A stirring shaft 402 is connected to the lower end of the stirring motor 401 by a key. A connecting plate 403 is rotatably connected to the surface of the stirring shaft 402. A sun gear 404 is arranged below the connecting plate 403. A planetary gear 405 is meshed with one side of the sun gear 404. On the other side of 5, a gear ring 406 is meshed with. A central stirring blade 407 is fixedly connected to the inner side of the sun gear 404. An outer stirring blade 408 is fixedly connected to the inner side of the planetary gear 405. A connecting rod 409 is rotatably connected to the lower end of the outer stirring blade 408. A rotating gear 410 is fixedly connected to the lower end of the stirring shaft 402. A dispersing disc 411 is fixedly connected to the lower end of the rotating gear 410. Dispersing teeth 412 are fixedly connected to the surface of the dispersing disc 411. A discharge hole 413 is opened on the inner side of the dispersing teeth 412.

[0023] Furthermore, a heating wire 2 is provided on the inner side of the mixing tank body 1, and a feed inlet 3 is provided at the upper end of the mixing tank body 1. The heating wire 2 is used to heat the latex paint. Heating can reduce the viscosity of the latex paint, making it easier to mix and disperse. The feed inlet 3 is used to add the raw materials or additives of the latex paint into the tank, which facilitates the input of materials.

[0024] Furthermore, the stirring shaft 402 is fixedly connected to the rotating plate 403, the sun gear 404, and the central stirring blade 407, and is connected to the rotating gear 410. There are two sets of external stirring blades 408. The stirring shaft 402 is connected to the rotating plate 403, the sun gear 404, and the central stirring blade 407, and is rotatably connected to the rotating gear 410, ensuring that power can be transmitted from the stirring motor 401 to each stirring component, realizing the linkage of the entire stirring system. There are two sets of external stirring blades 408. Driven by the planetary gear 405, a wider stirring range is achieved, covering the edge and side of the tank, preventing material accumulation, and improving mixing efficiency.

[0025] Furthermore, the stirring motor 401 forms a rotating structure with the dispersing disk 411 through the stirring shaft 402 and the rotating gear 410. Multiple sets of dispersing teeth 412 are provided, and multiple feeding holes 413 are provided. The stirring motor 401 drives the dispersing disk 411 to rotate at high speed through the stirring shaft 402 and the rotating gear 410. The multiple sets of dispersing teeth 412 on the dispersing disk 411 can strongly disperse the latex paint, so that the material is fully mixed in the high-speed rotation. The multiple feeding holes 413 opened on the inner side of the dispersing teeth 412 facilitate the flow and mixing of the material, ensuring that the material can be evenly distributed during the dispersion process.

[0026] Furthermore, a guide plate 5 is provided below the dispersing disc 411. A discharge port 6 is provided at the lower end of the guide plate 5. A spiral conveyor chamber 7 is provided at the lower end of the discharge port 6. A spiral conveyor shaft 8 is rotatably connected to the inner side of the spiral conveyor chamber 7. A spiral conveyor motor 9 is connected to one end of the spiral conveyor shaft 8 with a flat key. A discharge port 10 is provided on the lower surface of the spiral conveyor chamber 7. The guide plate 5 is used to guide the flow direction of the latex paint, so that it flows smoothly to the bottom of the tank. Then, it enters the inner side of the spiral conveyor chamber 7 through the discharge port 6. The spiral conveyor shaft 8 inside, driven by the spiral conveyor motor 9, further conveys the latex paint discharged from the discharge port 6 to the discharge port 10, ensuring that the material can be discharged and collected smoothly.

[0027] Furthermore, a vacuum pump 11 is installed on the upper surface of the spiral conveyor chamber 7. A vacuum pipe 12 is fixedly connected to the upper end of the vacuum pump 11. A valve 13 is installed on the surface of the vacuum pipe 12. An exhaust pipe 14 is provided on the outside of the vacuum pipe 12. A separation chamber 15 is fixedly connected to the other end of the exhaust pipe 14. An exhaust hole 16 is opened at the upper end of the separation chamber 15, and a drain hole 17 is opened at the lower end of the separation chamber 15. The vacuum pump 11 creates a negative pressure environment in the mixing tank through the vacuum pipe 12 to remove bubbles and impurities in the latex paint and improve product quality. The valve 13 installed on the surface of the vacuum pipe 12 is used to control the vacuum degree. Then, the exhaust pipe 14 transports the gas and impurities extracted by the vacuum pump 11 to the separation chamber 15. The separation chamber 15 discharges the gas through the exhaust hole 16 and discharges the liquid impurities through the drain hole 17.

[0028] As can be seen from the above technical solution, during use, firstly, the raw materials and additives for latex paint are added into the tank through the feed port 3 at the upper end of the mixing tank body 1. The heating wire 2 inside the mixing tank body 1 then starts working to heat the latex paint. Heating reduces the viscosity of the latex paint, making it easier to mix and disperse, thereby improving the efficiency of subsequent stirring and dispersion. Secondly, the stirring motor 401 is started. The stirring motor 401 drives the entire stirring system through the stirring shaft 402. The stirring shaft 402 drives the sun gear 404 to rotate, and the central stirring blade 407 fixed inside the sun gear 404 rotates accordingly. The latex paint in the central area of ​​the tank is stirred. The sun gear 404 meshes with the planetary gear 405. While rotating, the planetary gear 405 revolves around the sun gear 404, driving the outer stirring blades 408 inside it to rotate. Since there are two sets of outer stirring blades 408, and they are driven by the planetary gears 405, a wider stirring range can be achieved, covering the edges and sides of the tank, preventing material accumulation and improving mixing efficiency. The stirring shaft 402 drives the dispersion disc 411 to rotate at high speed via the rotating gear 410. Multiple sets of dispersion teeth 412 on the dispersion disc 411 strongly disperse the latex paint, making it... The materials are thoroughly mixed during high-speed rotation. Multiple feeding holes 413 on the inner side of the dispersing teeth 412 facilitate the flow and mixing of materials, ensuring uniform distribution during dispersion. Then, the vacuum pump 11 installed on the upper surface of the spiral conveyor chamber 7 is activated, creating a negative pressure environment in the mixing tank through the vacuum pipe 12 to remove bubbles and impurities from the latex paint, improving product quality. Valves 13 installed on the surface of the vacuum pipe 12 are used to control the vacuum level to adapt to different production needs. The gas and impurities extracted by the vacuum pump 11 are transported to the separation chamber 15 through the exhaust pipe 14, and the separation chamber 15 is vented through the exhaust port 16. Gas is released, and liquid impurities are discharged through drain hole 17, achieving gas-liquid separation and further improving the purity of latex paint. Finally, after stirring and dispersing, the latex paint flows to the bottom of the tank through discharge hole 413 under the action of gravity, and is guided by guide plate 5 to discharge port 6 at its lower end. The latex paint enters the inner side of spiral conveyor chamber 7 from discharge port 6. Spiral conveyor shaft 8 is rotatably connected to the inner side of spiral conveyor chamber 7. Spiral conveyor shaft 8 is driven by spiral conveyor motor 9 to further transport the latex paint to discharge port 10, ensuring that the material can be discharged and collected smoothly. This completes the use of a mixing tank for latex paint production.
