Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a dispersing disc for a horizontal sand mill. Background Technology

[0002] Epoxy floor coatings are composed of epoxy resin, curing agents, pigments, fillers, and other components. To achieve excellent performance characteristics such as high gloss, high hiding power, good abrasion resistance, and corrosion resistance, the solid particles, including pigments and fillers, need to be ground to an extremely fine particle size, typically at the micron or even nanometer level, and uniformly dispersed within the resin system. This requires a horizontal sand mill. A horizontal sand mill is a highly efficient wet ultra-fine grinding and dispersing machine. Its closed-loop continuous production effectively prevents material drying and crusting or solvent evaporation, helping to ensure product quality stability. Furthermore, horizontal sand mills have a larger sand capacity and higher grinding efficiency, making them suitable for large-scale epoxy floor coating production. During the grinding process, the horizontal sand mill disperses and mixes the pigments and fillers through a dispersing disc; therefore, the dispersing capacity of the dispersing disc determines the working efficiency of the horizontal sand mill.

[0003] Chinese utility model patent application number 202421704539.0 discloses a dispersing disc for a horizontal sand mill. This patent improves the material dispersion effect by setting an extension plate on the outside of the dispersing disc. However, the extension plate of this patent is fixedly set and rotates with the dispersing disc, which causes the material to flow relatively stably, resulting in limited dispersion and mixing effect.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0021] Example 1:

[0022] like Figure 1-4 As shown:

[0023] This utility model provides a dispersing disc for a horizontal sand mill, comprising a dispersing disc body 1, a connecting assembly, an annular frame 3, and a plurality of dispersing strips 4; the dispersing disc body 1 includes a first surface 11, which is the side of the dispersing disc body 1 facing the discharge direction of the sand mill; the annular frame 3 is mounted on the first surface 11 through the connecting assembly; the annular surface of the annular frame 3 is parallel to the first surface 11; the plurality of dispersing strips 4 are distributed in a ring along the periphery of the annular frame 3; one end of the dispersing strip 4 is provided with a connecting shaft 41; the connecting shaft 41 is perpendicularly connected to the annular surface of the annular frame 3; one end of the dispersing strip 4 is movably connected to the annular frame 3 through the connecting shaft 41.

[0024] When the dispersing disc of the horizontal sand mill provided by this utility model needs to stir and mix materials, the dispersing disc body 1 is driven to rotate by the drive shaft of the horizontal sand mill; during the rotation of the dispersing disc body 1, the annular frame 3 and the dispersing strips 4 are driven synchronously. Since the ends of the dispersing strips 4 are movably connected to the annular frame 3 through the connecting shaft 41, when the dispersing strips 4 rotate with the dispersing disc body 1, the forces on different surfaces of the dispersing strips 4 are different due to the different compositions of the materials. Therefore, the dispersing strips 4 will exhibit an irregular oscillation state due to centrifugal force and material resistance during rotation. Compared with the fixed structure of the extension plate, this irregular movement breaks the relatively stable flow state of the materials, greatly increases the degree of material disturbance, and can generate additional shear force and impact force, promoting further crushing and dispersion of material particles and enhancing the mixing effect. At the same time, the oscillation of the dispersing strips 4 can also drive the exchange of materials in different areas, promote a more uniform distribution of materials in the grinding chamber, reduce local concentration differences, and improve the overall stirring efficiency.

[0025] The present invention provides a dispersing disc for a horizontal sand mill, which effectively increases the agitation of the material by setting dispersing strips 4 that can rotate and swing with the dispersing disc body 1, thereby promoting further crushing and dispersion of material particles and enhancing mixing efficiency.

[0026] Since the dispersing disc body 1 rotates in a fixed direction, the side of the dispersing strip 4 facing this direction will have more contact with the material. In order to improve the grinding effect of the dispersing strip on the material, in a preferred embodiment, the dispersing strip 4 includes a first side; the first side is located on the side facing the rotation direction of the dispersing disc body 1; a first through groove 42 is formed on the first side along the length direction of the dispersing strip 4; a plurality of rollers 43 are provided in the first through groove 42; the plurality of rollers 43 are arranged along the length direction of the dispersing strip 4; the two ends of the rollers 43 are movably connected to both sides of the inner wall of the first through groove 42.

[0027] When the material contacts the first side of the dispersing strip 4, the first channel 42 acts as a guide, directing the material to flow in a specific direction and creating a more orderly circulating flow field within the grinding chamber. This orderly flow field reduces eddies and turbulence on the back side of the dispersing strip 4, lowering flow resistance. Furthermore, the rotatable roller 43 within the first channel 42 allows the material to be subjected to the squeezing force of the roller 43 and the side of the first channel 42 as it flows through, promoting secondary crushing and mixing and further improving mixing efficiency.

[0028] The present invention provides a dispersing disc for a horizontal sand mill, which promotes secondary crushing and mixing of materials by setting rollers 43 on the material-facing surface of the dispersing strips 4, thereby effectively improving the mixing efficiency.

[0029] When the dispersing bar 4 contacts the material on its receiving side, a stable flow layer forms on its back side, which reduces the mixing efficiency between different components of the material. To disrupt this stable flow layer, in a preferred embodiment, the dispersing bar 4 includes a second side; this second side is located on the side opposite to the direction of rotation of the dispersing disc body 1; a second groove 44 is formed on the second side along the length of the dispersing bar 4; several fins 45 are provided within the second groove 44; the fins 45 are arranged along the width of the second groove 44. During rotation, the fins 45 on the second side of the dispersing bar 4 disrupt the stable flow layer formed on the back side of the material, generating tiny turbulent regions. These tiny turbulences increase the probability of collisions between materials, resulting in finer dispersion of the material initially mixed on the front side of the dispersing bar 4, compensating for potential unevenness in the front mixing process. Simultaneously, the fins 45 also increase the structural stability of the dispersing bar 4 to a certain extent, reducing the problem of deformation caused by excessive swaying amplitude due to material impact.

[0030] The present invention provides a dispersing disc for a horizontal sand mill. By setting fins 45 on the back of the dispersing strip 4, a small turbulent area can be generated on the back of the dispersing strip 4, which can further disperse the material that has been initially mixed on the front of the dispersing strip 4, and make up for the unevenness that may exist in the front mixing.

[0031] In a preferred embodiment, the connecting component includes a plurality of connectors 2; the plurality of connectors 2 are arranged circumferentially on the first surface 11; one end of each connector 2 is fixedly connected to the first surface 11; and the other end of each connector 2 is fixedly connected to the ring frame 3. Providing multiple connectors 2 can increase the contact area with the material during rotation, thereby increasing the mixing force.

[0032] In a preferred embodiment, the connecting body 2 is a square frame structure; the square hole in the middle of the frame of the connecting body 2 faces the rotation direction of the dispersing disk body 1. Providing a square hole in the middle of the connecting body 2 reduces travel resistance and allows material to pass through, resulting in a cutting and crushing effect on the material and effectively improving mixing efficiency.

[0033] In a preferred embodiment, the ring frame 3 is a ring-shaped sheet structure; the ring frame 3 is coaxially arranged with the dispersion disk body 1.

[0034] In a preferred embodiment, the dispersing disc body 1 further includes a second surface; the second surface is the side of the dispersing disc body 1 facing the feed direction of the sand mill; the second surface is provided with an annular protrusion 12; the annular protrusion 12 covers the second surface; the thickness of the annular protrusion 12 gradually decreases in the direction towards the side of the dispersing disc body 1. The second surface of the dispersing disc body 1 is the material-facing surface. If the second surface is flat, material accumulation may occur. To avoid material accumulation, an annular protrusion 12 with a central protrusion and a slope forming on the periphery is provided, which allows the material to pass quickly through the second surface area, avoiding accumulation.
