Description

Technical Field

[0001] This application relates to the field of mixing technology, and in particular to a dual-flow dispersion disc. Background Technology

[0002] In dispersion processes across chemical, coating, new energy, and pharmaceutical industries, the dispersion disc, as a core component of high-speed dispersers and mixing equipment, directly impacts shear force, flow field distribution, and mixing efficiency. Traditional fixed-diameter dispersion discs require selection based on specific process requirements (e.g., material viscosity, target particle size, throughput). However, when facing production demands involving multiple product types and operating conditions, fixed-diameter dispersion discs often struggle to simultaneously meet the process requirements of different stages, such as balancing high-shear dispersion and macroscopic mixing. To address this issue, adjustable-diameter dispersion discs have been developed. By dynamically adjusting the diameter, this dispersion disc allows the same device to adapt to different process requirements, enhancing the adaptability of the mixing equipment. Furthermore, selecting dispersion discs with different diameters eliminates the need for cumbersome disassembly and assembly procedures. Utility Model Content

The adjusting disc rotating sleeve 103 is located at the center of the adjusting disc body 101, and the arc-shaped slide groove 102 is located on the adjusting disc body 101. The center trajectory of the arc-shaped slide groove 102 starts from a certain distance from the outer wall of the adjusting disc rotating sleeve 103 and extends circumferentially away from the center of the adjusting disc body 101. The curvature of the arc-shaped slide groove 102 gradually decreases from the starting end to the ending end.

[0033] The arc-shaped slide groove 102 is provided in multiple ways along the circumference with the center of the adjusting disc body 101 as the reference, and preferably there are 6 arc-shaped slide grooves 102.

[0034] like Figure 4As shown, the stirring paddle 20 includes a telescopic frame 201, a fixing member 202, and a dual-flow paddle 203; the telescopic frame 201 also includes a telescopic frame body 2011, an adjusting shaft 2012, and a sliding shaft 2013; the telescopic frame body 2011 has a plate-like structure; a single adjusting shaft 2012 and multiple sliding shafts 2013 are provided on the upper and lower sides of one end of the telescopic frame body 2011; the other end of the telescopic frame body 2011 is fixedly connected to the dual-flow paddle 203 through the fixing member 202, which can be a rivet or a screw, and correspondingly, rivet holes or threaded holes are opened on the telescopic frame body 2011 and the dual-flow paddle 203; there are multiple stirring paddles, the same number as the arc-shaped chute 102.

[0035] like Figure 4 As shown, the mixing disc 30 includes a mixing disc body 301, a radial groove 302, and a mounting shaft 303. The mixing disc body 301 has a disc structure, and the mounting shaft 303 is a hollow shaft located at the center of the mixing disc body 301. The radial groove 302 starts at a certain distance from the mounting shaft 303 and extends radially along the mixing disc body 301 to terminate at a certain distance from the outer edge of the mixing disc body 301. The mixing disc body 301 can be designed as a hollow disc structure. The upper end of the mounting shaft (303) has a threaded hole radially provided, which is fixed to the mixing shaft by mounting screws.

[0036] Radial chute 302 is provided in multiple circumferential directions with the center of the mixing plate body 301 as the reference, and the number is the same as that of arc-shaped chute 102.

[0037] Multiple sliding shafts 2013 on the lower side of the telescopic frame body 2011 are embedded in the radial sliding groove 302 and slide in cooperation with the radial sliding groove 302; a single adjusting shaft 2012 on the upper side of the telescopic frame body 2011 is embedded in the arc-shaped sliding groove 102 and slides in cooperation with the radially arranged arc-shaped sliding groove 102; the adjusting disc rotating sleeve 103 is sleeved on the mounting shaft 303, and is coaxially arranged with the mounting shaft 303, and can rotate relative to each other; preferably, the upper end of the mounting shaft (303) is radially provided with a threaded hole, and is fixed to the stirring shaft by mounting screws. That is, the stirring paddle 20 is slidably connected to the adjusting disc 10 and the stirring disc 30 respectively through the single adjusting shaft 2012 and multiple sliding shafts 2013 on the upper and lower sides of one end of the telescopic frame body 2011, and is sandwiched between the adjusting disc 10 and the stirring disc 30. The number of sliding shafts 2013 is preferably two.

[0038] like Figures 6-7 As shown, the top and bottom views of the dual-flow dispersion disc involved in this application are displayed when it is adjusted to a certain stirring diameter. As shown in the figure, in order to improve the stability of the sliding shaft 2013 sliding in the radial groove 302, a retaining spring can be further provided at the end of the sliding shaft 2013 to reduce the shaking of the sliding shaft 2013 during sliding and improve the smoothness of the adjustment process.

[0039] The mounting shaft 303 has a threaded mounting hole in the radial direction, which is fixedly connected to the rotating shaft 40 by a first fixing screw to achieve fixed installation of the dispersion disc; the adjusting disc rotating sleeve 103 has a threaded mounting hole in the radial direction, which is fixedly connected to the mounting shaft 303 by a second screw. When it is necessary to adjust the stirring diameter of the agitator, loosen the second fixing screw and rotate the adjusting disc 10.

[0040] To facilitate the adjustment of the adjustment disc 10, the outer contour of the adjustment disc rotating sleeve 103 can be set to a regular hexagon similar to the outer contour of a nut, so that users can use tools such as wrenches to rotate the adjustment disc 10 to achieve radial adjustment of the stirring paddle 20 on the stirring disc 30. Figure 8 The diagram shows the top view of the dispersing disk when it is stretched to different diameters.

[0041] This invention utilizes the combination of upper and lower sliding grooves to allow the stirring paddle to extend and retract radially at will. It features a simple structure that is easy to clean and maintain. Furthermore, it allows for the selection of different dispersion disc diameters using a single device, thus improving the applicability of the stirring structure to various raw materials and processes.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
