Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a novel dispersing machine. Background Art

[0002] In the process of coating production, a dispersing machine is a very important device, mainly used to evenly disperse solid particles such as pigments and fillers in a liquid medium such as a resin solution to form a stable and well-performing coating.

[0003] In the current dispersing machine, the dispersing disc is often fixedly arranged at a certain position inside the cylinder. The dispersing disc working at a fixed position may leave some areas that are difficult to reach, resulting in insufficient treatment of the coating in these places. At the same time, the stirring direction of the dispersing disc is single, and the dispersing and mixing effect of the coating is poor, with low efficiency. Summary of the Invention

[0005] To achieve the above object, the utility model adopts the following technical solutions: A novel dispersing machine includes a cylinder body. The bottom of the cylinder body is provided with a discharge port, and the top of the side wall is provided with a plurality of feed ports. A power box is installed on the top of the cylinder body. An internal gear ring is rotatably connected to the inner wall of the power box. A central shaft is rotatably connected through the upper and lower centers of the power box. A central gear is fixedly arranged on the central shaft located inside the power box. Three sub-gears are circumferentially and evenly meshed between the internal gear ring and the central gear. A spline sleeve is fixedly arranged at the center of the sub-gear. Connecting sleeves corresponding to the spline sleeve are provided at the top and bottom inside the power box. The top and bottom of the spline sleeve are respectively rotatably connected inside the corresponding connecting sleeves. A spline shaft penetrates through the spline sleeve. The spline shaft penetrates through the power box. A mounting bracket is installed on the top of the power box. A motor for driving the central shaft to rotate is installed at the center of the bracket. Three electric push rods corresponding to the spline shaft and passing through the bracket are provided on the top of the power box. A lifting plate is fixedly connected to the top of the push rod of the electric push rod. The top of the spline shaft passes through the bracket and is rotatably connected to the lifting plate. A dispersing disc assembly is installed on the spline shaft.

[0006] Specifically, a flange is correspondingly provided at the bottom edge of the side wall of the power box and the top edge of the side wall of the cylinder body. The upper and lower flanges are connected and fixed by bolts and nuts.

[0007] Specifically, connecting rods are provided between every two of the three connecting sleeves in the upper layer and between every two of the three connecting sleeves in the lower layer.

[0008] Specifically, the dispersing disc assembly includes a first dispersing disc. The first dispersing disc is fixedly connected to the bottom of the spline shaft, and the lengths of the spline shaft located inside the cylinder body are different. The first dispersing discs are arranged staggered up and down.

[0009] Specifically, the dispersion disk assembly includes a second dispersion disk. Several pairs of second dispersion disks are fixedly connected up and down at the bottom of the spline shaft, and the lengths of the spline shaft located inside the cylinder are the same.

[0010] Specifically, a rotating shaft is installed at the bottom of the central shaft, and a scraper in contact with the inner wall of the cylinder is installed at the bottom of the rotating shaft. The scraper is U-shaped, and several stirring rods are arranged on the vertical inner side of the scraper from top to bottom. The second dispersion disk does not contact the rotating shaft.

[0018] The present utility model will be further described below with reference to the drawings and embodiments:

[0019] Embodiment 1

Flanges are correspondingly provided at the bottom edge of the side wall of the power box 4 and the top edge of the side wall of the cylinder body 1, and the upper and lower flanges are connected and fixed by bolts and nuts.

[0021] An internal gear ring 5 is rotatably connected to the inner wall of the power box 4. A central shaft 6 is rotatably connected through the upper and lower centers of the power box 4. A central gear 7 is fixedly provided on the central shaft 6 located inside the power box 4. Three sub-gears 8 are circumferentially and evenly meshed between the internal gear ring 5 and the central gear 7. A spline sleeve 9 is fixedly provided at the center of the sub-gear 8. Connecting sleeves 10 corresponding to the spline sleeve 9 are provided at the top and bottom of the power box 4. The top and bottom of the spline sleeve 9 are respectively rotatably connected inside the corresponding connecting sleeves 10. Connecting rods 16 are provided between every two of the three connecting sleeves 10 in the upper layer and between every two of the three connecting sleeves 10 in the lower layer.

A mounting bracket 12 is installed at the top of the power box 4, and a motor 13 for driving the central shaft 6 to rotate is installed at the center of the bracket 12.

[0022] Three electric push rods 14 corresponding to the spline shaft 11 and passing through the bracket 12 are provided at the top of the power box 4. A lifting plate 15 is fixedly connected to the top of the push rod of the electric push rod 14. The top of the spline shaft 11 passes through the bracket 12 and is rotatably connected to the lifting plate 15. A dispersing disc assembly is installed on the spline shaft 11. The dispersing disc assembly includes a first dispersing disc 17. The first dispersing disc 17 is fixedly connected to the bottom of the spline shaft 11, and the lengths of the spline shaft 11 located inside the cylinder body 1 are different. The first dispersing discs 17 are arranged in an upper and lower staggered manner.

[0023] During use, each raw material of the coating enters the cylinder body 1 through the feed port 3. The motor 13 drives the central shaft 6 to rotate. The central gear 7 drives the sub-gear 8 to rotate. The sub-gear 8 drives the internal gear ring 5 to rotate. When the sub-gear 8 rotates, it drives the spline sleeve 9 to rotate, and then drives the spline shaft 11 to rotate. At this time, the first dispersing disc 17 rotates, and starts to disperse each raw material of the coating. During the dispersing process, the electric push rod 14 controls the lifting of the spline shaft 11, so that the first dispersing disc 17 can move up and down while rotating, and stir and disperse the coating in layers, which can effectively improve the mixing efficiency. After mixing, it can be discharged through the discharge port 2.

[0024] Embodiment 2

[0025] As Figures 2 - 4 shown in Figures 2 - 4 , a new type of dispersing machine includes a cylinder body 1. A discharge port 2 is provided at the bottom of the cylinder body 1, and a plurality of feed ports 3 are provided at the top of the side wall. A power box 4 is installed at the top of the cylinder body 1. Flanges are correspondingly provided at the bottom edge of the side wall of the power box 4 and the top edge of the side wall of the cylinder body 1, and the upper and lower flanges are connected and fixed by bolts and nuts.

[0026] An internal gear ring 5 is rotatably connected to the inner wall of the power box 4. A central shaft 6 is rotatably connected through the upper and lower centers of the power box 4. A central gear 7 is fixedly arranged on the central shaft 6 located inside the power box 4. Three sub-gears 8 are evenly meshed circumferentially between the internal gear ring 5 and the central gear 7. A spline sleeve 9 is fixedly arranged at the center of the sub-gear 8. Connection sleeves 10 corresponding to the spline sleeve 9 are arranged at the top and bottom inside the power box 4. The top and bottom of the spline sleeve 9 are respectively rotatably connected inside the corresponding connection sleeves 10. Connecting rods 16 are arranged between every two of the three connection sleeves 10 in the upper layer and between every two of the three connection sleeves 10 in the lower layer. A spline shaft 11 penetrates through the spline sleeve 9. The spline shaft 11 penetrates through the power box 4. A mounting bracket 12 is installed at the top of the power box 4. A motor 13 for driving the central shaft 6 to rotate is installed at the center of the bracket 12.

[0027] Three electric push rods 14 corresponding to the spline shaft 11 and passing through the bracket 12 are arranged at the top of the power box 4. A lifting plate 15 is fixedly connected to the top of the push rod of the electric push rod 14. The top of the spline shaft 11 passes through the bracket 12 and is rotatably connected to the lifting plate 15. A dispersion disc assembly is installed on the spline shaft 11. The dispersion disc assembly includes a second dispersion disc 18. Several pairs of second dispersion discs 18 are fixedly connected up and down at the bottom of the spline shaft 11, and the lengths of the spline shaft 11 located inside the cylinder 1 are the same. A rotating shaft 19 is installed at the bottom of the central shaft 6. A scraping plate 20 in contact with the inner wall of the cylinder 1 is installed at the bottom of the rotating shaft 19. The scraping plate 20 is U-shaped. Several stirring rods 21 are arranged on the vertical inner side of the scraping plate 20 from top to bottom. The second dispersion disc 18 does not contact the rotating shaft 19.

[0028] During use, each raw material of the coating enters the cylinder 1 through the feed port 3. The motor 13 drives the central shaft 6 to rotate. The central gear 7 drives the sub-gear 8 to rotate. The sub-gear 8 drives the internal gear ring 5 to rotate. When the sub-gear 8 rotates, it drives the spline sleeve 9 to rotate, and then drives the spline shaft 11 to rotate. At this time, the second dispersion disc 18 rotates and starts to disperse each raw material of the coating. During the dispersion process, the electric push rod 14 controls the lifting of the spline shaft 11, so that the second dispersion disc 18 can move up and down while rotating, and stir and disperse the coating in layers, which can effectively improve the mixing efficiency. After mixing is completed, it can be discharged through the discharge port 2. During this period, the rotating shaft 19 drives the scraping plate 20 and the stirring rods 21 to rotate, which can scrape off the coating attached to the cylinder wall, and the stirring rods 21 can further improve the mixing effect.

[0029] By moving up and down, the first dispersion disc 17 and the second dispersion disc 18 can come into contact with the coatings at different levels inside the cylinder body 1, ensuring that all materials from the top to the bottom can be fully mixed and dispersed; it helps to break up the aggregates in the coating and promotes the uniform distribution of solid particles such as pigments and fillers in the liquid medium, not only improving the dispersion effect but also shortening the time to reach the required dispersion degree; the design of the up-and-down movement of the first dispersion disc 17 and the second dispersion disc 18 can help eliminate "dead corners", making the coatings inside the entire cylinder body 1 be evenly stirred; the up-and-down movement of the first dispersion disc 17 and the second dispersion disc 18 changes the fluid flow pattern, increases the degree of turbulence, and thus enhances the mixing effect.
