Abstract
Description
Technical Field
[0001] This application relates to the technical field of industrial automation equipment, and particularly to a granulating and mixing dual-functional dispersion disc. Background Art
[0002] The descriptions in this section only provide background information related to the present disclosure and do not constitute prior art. In the related art of the colorful paint production process, the material to be granulated is first transferred to a mobile pulling tank, and then a granulating dispersion disc is used to break the material to form colored dots. Since the granulating dispersion disc only has the granulating function, after granulation, it is necessary to transfer the colored dots of different sizes produced by different granulating processes into the mixing kettle, and then use the stirring paddle in the mixing kettle to mix them evenly. A large number of mobile pulling tanks are required during the production process, resulting in a large investment in equipment and a large occupied area of the production site. In addition, the material is discharged from the pulling tank to the mixing kettle in the form of DN50 and DN80 ball valves, and there is a large waste of human efficiency during the process of transporting the material and waiting for the discharging to end. The cleaning of the mobile pulling tank after use also occupies a lot of manpower. The above-mentioned factors are the key reasons restricting the production efficiency of the granulating process. Summary of the Invention
[0003] In view of this, this application provides a granulating and mixing dual-functional dispersion disc, which can not only granulate but also mix colored dots, reducing the occupation of manpower and production equipment by material turnover and improving production efficiency.
[0004] To achieve the above object, this application is realized through the following technical solutions:
[0005] A granulating and mixing dual-functional dispersion disc, characterized in that: it includes a central shaft and multiple groups of dispersion blades; each dispersion blade is arranged on the central shaft at intervals in the circumferential direction around the central shaft, and each dispersion blade includes a plurality of cutting prisms and a bracket for fixedly connecting the cutting prisms to the central shaft, and the cutting prisms are arranged on the bracket at intervals in the radial direction along the central shaft; a cutting sharp part is arranged on one side of the cutting prism, and a stirring blunt part is arranged on the back of the cutting sharp part, so that when the central shaft rotates forward, the cutting sharp part can break the material, and when the central shaft rotates backward, the stirring blunt part can stir the material.
[0006] For the above-mentioned granulation and mixing dual-functional dispersion disk of the present application, during use, it is connected to the main shaft of the stirring motor of the production kettle through the central shaft. The stirring motor supports forward and reverse rotation. When the dispersion disk rotates forward, the cutting sharp part of the dispersion disk cuts the material in the production cylinder, breaking it into independent colored dots with a size of 1 mm to 5 mm. Different granulation rotation speeds and durations can cut colored dots of different sizes. Add colored dots of different sizes produced in other granulation steps into the production kettle with the largest number of granulations, control the dispersion disk to rotate in reverse, and the stirring blunt part of the dispersion disk can start to mix the colored dots until they are uniform. The dispersion disk can reduce the number of manual feeding during material transfer, reduce the occupation of the production cylinder, speed up the granulation and mixing efficiency, and improve the production efficiency.
[0007] In some embodiments, the bracket includes an upper cross bar and a lower cross bar that are fixedly connected to the central shaft at one end and are arranged horizontally in a high-low parallel manner. Both the upper cross bar and the lower cross bar are horizontally arranged along the radial direction of the central shaft; the cutting prism is a triangular prism, and the upper and lower bottom surfaces of the cutting prism are respectively fixedly connected to the upper cross bar and the lower cross bar. The side surface of the cutting prism includes an inner side surface, an outer side surface, and a stirring surface. The angle between the inner side surface and the outer side surface is an acute angle, and the angle between the outer side surface and the stirring surface is an obtuse angle. The outer side surface is perpendicular to the axial direction of the upper cross bar and the lower cross bar, and the inner side surface is located on the side facing the central shaft, and the outer side surface is located on the side facing away from the central shaft. The sharp part formed by the sharp corners of the inner side surface and the outer side surface constitutes the cutting sharp part, and the stirring surface constitutes the stirring blunt part. When the dispersion disk rotates forward, the rotation direction of the dispersion disk is consistent with the cutting edge direction of the cutting prism. When rotating in reverse, the rotation direction of the dispersion disk is opposite to the cutting edge direction of the cutting prism.
[0008] In some embodiments, the spacing between adjacent cutting prisms in the same dispersion blade is unevenly distributed, and is arranged in a manner of being sparse on the outside and dense on the inside. This sparse-on-the-outside-and-dense-on-the-inside means that the spacing between adjacent cutting prisms far from the central shaft is larger, and the spacing between adjacent cutting prisms close to the central shaft is smaller. The purpose of this setting is that when the dispersion disk rotates, due to the equal angular velocity, the linear velocity of the outer edge of the dispersion disk is large, the interval is wide, and the friction between the dispersion disk and the material is small. Therefore, the relative velocity between the outer dispersion disk and the material becomes larger, improving the cutting efficiency.
[0009] In some embodiments, both the upper cross bar and the lower cross bar are triangular prisms with an isosceles triangle as the bottom surface, and the vertex angle of the isosceles triangle faces downward. During flushing, the water flow usually flushes obliquely from top to bottom. By setting the upper cross bar and the lower cross bar as an inverted isosceles triangular prism structure, compared with a square prism or other shaped prisms, it can reduce sanitary dead corners and facilitate the cleaning of attached materials. The vertex angle range of the isosceles triangular prism is between 15° and 90°.
[0010] In some embodiments, a concave groove is provided on the upper bottom surface of the cutting prism, and the groove is fitted and installed at the bottom of the upper cross bar, so that the top surface of the upper cross bar is embedded in the upper bottom surface of the cutting prism, and the two edges of the top surface of the lower cross bar intersect with the two edges of the inner side surface of the cutting prism respectively.
[0011] Embedding the top surface of the upper cross bar into the upper bottom surface of the cutting prism can reduce the sanitary dead corners and facilitate flushing. Further, the intersection of the two edges of the top surface of the lower cross bar with the two edges of the inner side surface of the cutting prism is also provided to reduce the sanitary dead corners at the lower part of the cutting prism.
[0012] In some embodiments, the cutting prism is fixed on the upper cross bar and the lower cross bar by welding, and the upper cross bar and the lower cross bar are connected to the central axis by welding. The welding method can avoid loosening and reduce the sanitary dead corners, facilitating the cleaning of the attached materials.
[0013] In some embodiments, the number of the dispersion blades is three, and the included angle between two adjacent dispersion blades is 120°. Arranging the dispersion blades at equal intervals can eliminate the shaking caused by resonance.
[0014] In some embodiments, the central axis includes a shaft body and a hollow shaft sleeve provided at the top of the shaft body and opening upward, and the hollow shaft sleeve is used for detachably fixing connection with the main shaft of the stirring motor.
[0015] The wall thickness of the hollow shaft sleeve is 5 mm to 10 mm, and its inner diameter meshes with the outer diameter of the main shaft of the stirring motor. By inserting the main shaft of the stirring motor into the shaft sleeve of the central axis, it can be locked on the main shaft of the stirring motor by bolts, and the dispersion motor can drive the dispersion disk to rotate. Moreover, after loosening the fixing bolts, the dispersion disk can be removed from the main shaft of the stirring motor, which is convenient for replacement when it is severely worn later.
[0016] In some embodiments, the width range of the outer side surface of the cutting prism is between 10 mm and 100 mm, the included angle range between the outer side surface and the inner side surface is between 0° and 60°, and the included angle range between the stirring surface and the outer side surface is between 90° and 180°. The height range of the cutting prism is between 100 mm and 2000 mm, and the cutting prism spacing range is between 10 mm and 100 mm.
[0017] In some embodiments, the ratio range of the height of the cutting prism to the inner height of the reaction kettle is between 20% and 80%. The ratio range of the diameter of the dispersion disk to the inner diameter of the reaction kettle is between 50% and 90%.
[0018] In some embodiments, all the components of the dispersion disk are made of alloy material, which can prevent product quality problems caused by rust.
[0019] As can be seen from the above technical solutions, the present application has at least the following advantages and positive effects:
[0020] 1. A granulation and mixing dual-functional dispersion disk of the present application is connected to the main shaft of the stirring motor of the production kettle through a central shaft during use. The stirring motor supports forward and reverse rotation. When the dispersion disk rotates forward, the cutting sharp part of the dispersion disk cuts the materials in the production cylinder, breaking them into independent colored dots with a size of 1 mm to 5 mm. Different granulation rotation speeds and durations can cut colored dots of different sizes. Add colored dots of different sizes produced in other granulation steps into the production kettle with the largest number of granulations, and control the dispersion disk to rotate in reverse. The stirring blunt part of the dispersion disk can start mixing the colored dots until they are uniform. The dispersion disk can reduce the number of manual feeding times during material transfer, reduce the occupation of the production drawing cylinder, speed up the granulation and mixing efficiency, and improve the production efficiency.
[0021] 2. The present application can solve the problems of low granulation and mixing efficiency, large equipment capital investment, and high labor cost in the industry. By optimizing the structure of the dispersion disk and cooperating with the forward and reverse rotation functions of the dispersion disk, the granulation and mixing production processes are completed in the same kettle, completely eliminating the large occupation of production drawing cylinders, material handling waste, material loss, and the need for equipment operators caused by granulation and mixing in separate cylinders. The number of operators can be reduced by 50%, the demand for production drawing cylinders can be reduced by 80%, the demand for granulation dispersers can be reduced by 70%, the material loss can be reduced by 10%, the production of washing cylinder sewage can be reduced by 15%, and the production efficiency can be increased by 50%, significantly reducing the manufacturing cost of the granulation process.
[0022] 3. The dispersion disk of the present application uses a triangular prism to achieve the coupling function of granulation and mixing. By adjusting parameters such as the height, spacing, angle between adjacent side faces, and side width of the triangular prism, the granulation and mixing efficiency of the dispersion disk can be adjusted to adapt to the granulation and mixing performance requirements of production kettles with different volumes, and it has good compatibility.

[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation manners part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application.
[0034] Refer to Figures 1 to 8 , the embodiment of the present application provides a granulation and mixing dual-functional dispersion disk, which is characterized in that: it includes a central axis 1 and multiple groups of dispersion blades 2; each dispersion blade is arranged on the central axis 1 at intervals in the circumferential direction around the central axis 1, and each dispersion blade 2 includes several cutting prisms 3 and a bracket for fixedly connecting the cutting prisms 3 to the central axis 1, and each cutting prism 3 is arranged on the bracket at intervals in the radial direction along the central axis 1; a cutting sharp part 31 is arranged on one side of the cutting prism 3, and a stirring blunt part 32 is arranged on the back of the cutting sharp part 31, so that when the central axis 1 rotates forward, the cutting sharp part 31 can break the material, and when the central axis 1 rotates reversely, the stirring blunt part 32 can stir the material.
[0035] When in use, the dispersion disc is connected to the main shaft of the stirring motor of the production kettle through the central shaft 1. The stirring motor supports forward and reverse rotation. When the dispersion disc rotates forward, the cutting sharp part 31 of the dispersion disc cuts the materials in the production cylinder, breaking them into independent colored dots with a size of 1 mm to 5 mm. Different granulation rotation speeds and durations can cut colored dots of different sizes. Add colored dots of different sizes produced in other granulation steps into the production kettle with the largest number of granulations, and control the dispersion disc to rotate in reverse. Then, the stirring blunt part 32 of the dispersion disc can start mixing the colored dots until they are uniform. The dispersion disc can reduce the number of manual feeding times during material transfer, reduce the occupancy of the production cylinder, speed up the granulation and mixing efficiency, and improve the production efficiency.
[0036] The bracket includes an upper cross bar 4 and a lower cross bar 5 that are fixedly connected to one end of the central shaft 1 and are arranged in parallel at different heights. Both the upper cross bar 4 and the lower cross bar 5 are horizontally arranged along the radial direction of the central shaft 1; the cutting prism 3 is a triangular prism, and the upper and lower bottom surfaces of the cutting prism 3 are respectively fixedly connected to the upper cross bar 4 and the lower cross bar 5. The side surface of the cutting prism includes an inner side surface 33, an outer side surface 34, and a stirring surface 35. The angle between the inner side surface 33 and the outer side surface 34 is an acute angle, and the angle between the outer side surface 34 and the stirring surface 35 is an obtuse angle. The outer side surface 34 is perpendicular to the axial direction of the upper cross bar 4 and the lower cross bar 5, and the inner side surface 33 is located on the side facing the central shaft 1, while the outer side surface 34 is located on the side facing away from the central shaft 1. The sharp corners of the inner side surface 33 and the outer side surface 34 form the cutting sharp part 31, and the stirring surface 35 forms the stirring blunt part 32. When the dispersion disc rotates forward, the rotation direction of the dispersion disc is consistent with the direction of the cutting edge 37 of the cutting prism 3. When rotating in reverse, the rotation direction of the dispersion disc is opposite to the direction of the cutting edge 37 of the cutting prism 3.
[0037] The spacing between adjacent cutting prisms 3 in the same dispersion blade 2 is unevenly distributed, arranged in a way that is sparse on the outside and dense on the inside. This sparse-on-the-outside-and-dense-on-the-inside means that the spacing between adjacent cutting prisms 3 far from the central shaft 1 is larger, and the spacing between adjacent cutting prisms 3 close to the central shaft 1 is smaller. The purpose of this setting is that since the material to be cut is a solid-liquid two-phase mixture, the solid is heavier than the liquid and is prone to sinking. The dense spacing inside the dispersion disc has a large frictional force with the material, and can quickly stir the two-phase mixture during rotation so that it does not settle, preventing uneven sizes during cutting. The sparse spacing on the outside has a large linear velocity at the same angular velocity. Due to the sparse spacing, the frictional force with the material is small, and the material will not be driven by the dispersion disc to rotate too fast, resulting in a decrease in the relative velocity between the material and the outer dispersion disc and reducing the cutting efficiency.
[0038] Both the upper crossbar 4 and the lower crossbar 5 are triangular prisms with an isosceles triangle as the bottom surface, where the apex angle of the isosceles triangle faces downward. During flushing, the water flow usually flushes obliquely from top to bottom. By setting the upper crossbar 4 and the lower crossbar 5 as inverted isosceles triangular prism structures, compared with square prisms or prisms of other shapes, it can reduce sanitary dead corners and facilitate the cleaning of attached materials. The apex angle range of the isosceles triangular prism is between 15° and 90°.
[0039] The upper bottom surface of the cutting prism 3 is provided with a concave groove 36, and the groove 36 is fitted and installed at the bottom of the upper crossbar 4, so that the top surface of the upper crossbar 4 is embedded in the upper bottom surface of the cutting prism 3. Embedding the top surface of the upper crossbar 4 into the upper bottom surface of the cutting prism 3 can reduce sanitary dead corners and facilitate flushing.
[0040] The cutting prism 3 is fixed on the upper crossbar 4 and the lower crossbar 5 by welding, and the upper crossbar 4 and the lower crossbar 5 are connected to the central shaft 1 by welding. Using the welding method can prevent it from loosening, and at the same time reduce sanitary dead corners and facilitate the cleaning of attached materials.
[0041] The number of the dispersion blades 2 is three, and the included angle between two adjacent dispersion blades 2 is 120°. Setting the dispersion blades at equal intervals can eliminate the shaking caused by resonance.
[0042] The central shaft 1 includes a shaft body and a hollow shaft sleeve 11 provided at the top of the shaft body and opening upward. The hollow shaft sleeve 11 is used for detachably fixing connection with the main shaft of the stirring motor.
[0043] The wall thickness of the hollow shaft sleeve 11 is between 5 mm and 10 mm, and its inner diameter meshes with the outer diameter of the main shaft of the stirring motor. By inserting the main shaft of the stirring motor into the shaft sleeve of the central shaft 1, it can be locked on the main shaft of the stirring motor by bolts, and the dispersion motor can drive the dispersion disc to rotate. Moreover, after loosening the fixing bolts, the dispersion disc can be removed from the main shaft of the stirring motor, which is convenient for replacement when it is severely worn later.
[0044] The width range of the outer side surface 34 of the cutting prism 3 is between 10 mm and 100 mm, the included angle range between the outer side surface 34 and the inner side surface 33 is between 0° and 60°, and the included angle range between the stirring surface 35 and the outer side surface 34 is between 90° and 180°. The height range of the cutting prism 3 is between 100 mm and 2000 mm, and the spacing range of the cutting prisms 3 is between 10 mm and 100 mm.
[0045] The ratio range of the height of the cutting prism 3 to the inner height of the reaction kettle 6 is between 20% and 80%. The ratio range of the diameter of the dispersion disc to the inner diameter of the reaction kettle 6 is between 50% and 90%.
[0046] All the components of the dispersion disc are made of alloy materials, which can prevent product quality problems caused by rust.
[0047] The working process and usage method of the above embodiments are briefly described as follows:
[0048] During use, the material to be granulated is put into the production reaction kettle 6, and the dispersion disk is started to rotate forward for granulation. According to the size of the color dots on the standard template, the motor speed is slowly increased. When producing small color dots, the speed is adjusted higher, and when producing large color dots, the speed is adjusted lower. The dispersion disk is raised and lowered appropriately to fully stir the material in the kettle for cutting and granulation. Refer to Figure 5 and Figure 6 , when the dispersion disk rotates forward, the cutting edge 37 cuts the material into large color dots. Under the action of centrifugal force, the large color dots flow radially inward. During this process, they are continuously cut into smaller color dots by the outer cutting edge 37 until they move to the center of the dispersion axis and continue to move above and below the dispersion disk. Due to the continuous rotation, the test material always moves from the outside to the inner center axis 1 after being cut by 37. The material inside the center axis 1 is continuously squeezed to the upper and lower parts of the dispersion disk and then returns to the cylinder wall, and so on in a cycle until color dots of the expected size are obtained.
[0049] After granulation is completed, the emulsion produced in other processes is added into the production kettle, and the motor is started to rotate in reverse for mixing. The speed is slowly increased until a vortex appears in the center of the material. The dispersion disk is raised and lowered appropriately to fully stir and mix the material in the kettle. Refer to Figure 8 and Figure 9 , when the dispersion disk rotates in reverse, the color dots impact on the stirring surface 35 and flow radially outward. The color dots thrown out from the inner side surface 33 and the outer side surface 34 along the cutting edge 37 also flow radially outward under the action of centrifugal force. When the color dots encounter the outer vertical triangular prism at the next level, they are subjected to a stronger collision and centrifugal force, and the speed is further increased and they flow faster towards the cylinder wall. During this process, the color dots with different flow directions and speeds collide and mix with each other. During the rotation process, the material always moves from the inside of the center axis 1 towards the cylinder wall. After the material moves to the cylinder wall, it is continuously squeezed and moves along the cylinder wall to the upper and lower parts of the dispersion disk and returns to the center axis 1 of the dispersion disk, and so on in a cycle. Finally, the color dots of the expected size obtained during the forward rotation are mixed with the emulsion added to the reaction kettle during the reverse rotation to obtain a uniformly mixed finished product.
[0050] Figure 9 shows another embodiment of the present application, in which the lower cross bar 5 is slightly wider than the upper cross bar 4, and the two edges on the top surface of the lower cross bar 5 respectively intersect with the two edges of the inner side surface 33 of the cutting prism 3. This is provided to further reduce the sanitary dead corner at the lower part of the cutting prism 3.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them; although the embodiments of the present application have been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
