Description

Technical Field

[0001] This utility model relates to the field of pigment processing equipment, and more specifically, to a pigment reaction vessel and its stirring device. Background Technology

[0002] Pigment reaction vessel is a mixing device involved in the pigment production process. Pigment reaction vessel usually includes a vessel body and a stirring device installed in the vessel body. During operation, the operator puts the raw materials into the vessel body, and the stirring device stirs the raw materials evenly.

[0003] Since the raw materials may contain clumps, and the stirring device cannot effectively break up the clumps, this will affect the stirring effect of the raw materials and reduce the stirring efficiency of the pigment reactor.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pigment reaction vessel and its stirring device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stirring device, including a rotating shaft and a first support rod and a second support rod disposed on the outer peripheral wall of the rotating shaft. The first support rod is located directly above the second support rod. A first stirring roller is rotatably connected to the first support rod, and a second stirring roller is rotatably connected to the second support rod. The first stirring roller and the second stirring roller are arranged to rotate towards each other. The first stirring roller and the second stirring roller are used together to break up agglomerated materials. A fixed rod is provided in the rotating shaft, and a fixed wheel is fixed on the fixed rod. A first rotating wheel is provided on the first stirring roller and is tactilely connected to the fixed wheel. A second rotating wheel is provided on the second stirring roller and is tactilely connected to the first rotating wheel. The fixed wheel, the first rotating wheel and the second rotating wheel each include a frustum core and a rubber wheel wrapped around the frustum core.

[0007] The present invention is further configured such that: the first stirring roller is provided with a plurality of first protruding blocks for fitting against the outer peripheral wall of the second stirring roller, and the second stirring roller is provided with a plurality of second protruding blocks for fitting against the outer peripheral wall of the first stirring roller, wherein the center line of the second protruding block is located between the two first protruding blocks.

[0008] The present invention is further configured such that: the spacing between adjacent first protrusions is equal to the spacing between adjacent second protrusions, the first and second protrusions have the same shape, and the distance between adjacent first protrusions is at least three times the length of the first protrusion.

[0009] The present invention is further configured such that the first protruding block is shaped like a frustum.

[0010] A pigment reaction vessel includes a vessel body, a drive motor is provided at the bottom of the vessel body, the end of the rotating shaft is fixedly connected to the drive motor, and the top surface of the fixing rod is fixedly connected to the inner wall of the vessel body.

[0011] The present invention is further configured such that the vessel body is made of stainless steel.

[0012] In summary, this utility model has the following beneficial effects: During the rotation of the first and second agitating rollers along the rotating shaft, the raw materials can be stirred. When some clump-like materials are drawn in, the first and second agitating rollers, which rotate in opposite directions along the first and second support rods respectively, can effectively squeeze and break up the clump-like materials, achieving the dispersing effect of the agitating device on the clump-like materials. This allows the dispersed materials to combine better with other raw materials, reducing the residue of clump-like materials in the raw materials and ensuring the stirring efficiency of the agitating device.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0016] Stirring device, such as Figure 1 and Figure 2As shown, the device includes a rotating shaft 1 and a first support rod 2 and a second support rod 3 disposed on the outer peripheral wall of the rotating shaft 1. The first support rod 2 is located directly above the second support rod 3. A first agitating roller 4 is rotatably connected to the first support rod 2, and a second agitating roller 5 is rotatably connected to the second support rod 3. The first agitating roller 4 and the second agitating roller 5 are arranged to rotate in opposite directions. For example, when the first agitating roller 4 rotates clockwise, the second agitating roller 5 rotates counterclockwise, and vice versa. The first agitating roller 4 and the second agitating roller 5 are used together to break up agglomerated materials. A fixed rod 6 is provided in the rotating shaft 1, and a fixed wheel 7 is fixed on the fixed rod 6. A first rotating wheel 8 is provided on the first agitating roller 4 and is tactilely connected to the fixed wheel 7. A second rotating wheel 8 is provided on the second agitating roller 5 and is tactilely connected to the first rotating wheel 8. 9. When the mixing device is operating, the rotating shaft 1 drives the first support rod 2 and the second support rod 3 to rotate radially along the rotating shaft 1. The fixed rod 6 keeps the fixed wheel 7 stationary, so that the first rotating wheel 8, which is rolled and connected to the fixed wheel 7, drives the first stirring roller 4 to rotate radially along the first support rod 2 as the first support rod 2 rotates. At the same time, the second rotating wheel 9, which is rolled and connected to the first rotating wheel 8, rotates radially along the second support rod 3, thereby realizing the opposite rotation of the first stirring roller 4 and the second stirring roller 5. During the rotation of the first stirring roller 4 and the second stirring roller 5 along the rotating shaft 1, the raw materials can be stirred. When some clump-like materials are drawn in, the first stirring roller 4 and the second stirring roller 5, which rotate oppositely along the first support rod 2 and the second support rod 3 respectively, can achieve the stirring effect. The first and second agitation rollers 4 and 5 can effectively crush and disperse clumped materials, achieving the desired dispersing effect of the mixing device. This allows the dispersed materials to better combine with other raw materials, reducing residual clumped materials and ensuring the mixing efficiency of the mixing device. The fixed wheel 7, the first rotating wheel 8, and the second rotating wheel 9 all include a frustum-shaped core 14 and a rubber wheel 15 encased in the frustum-shaped core 14. The fixed wheel 7, the first rotating wheel 8, and the second rotating wheel 9 are all frustum-shaped. This design ensures that the torque transmission between the fixed wheel 7 and the first rotating wheel 8 requires a 90° rotation. The frustum-shaped core 14 ensures the shape of the fixed wheel 7, the first rotating wheel 8, and the second rotating wheel 9, guaranteeing the stability of the mixing device. The shape of the rotating wheel 7, the first rotating wheel 8, or the second rotating wheel 9 is as follows: the rubber wheel 15 is made of wear-resistant modified fluororubber, and the frustum core 14 is made of stainless steel. Specifically, the outer peripheral wall of the frustum core 14 is treated by sandblasting, and then the rubber wheel 15 is bonded to the frustum core 14 using a peroxide vulcanizing adhesive, ensuring the fixation between the frustum core 14 and the rubber wheel 15. The rubber wheel 15 made of this material can better ensure the stability of rolling in high-temperature environments, and the rubber wheel 15 has a large coefficient of friction, which can better ensure the transmission of torque, completing the synchronous rotation of the first agitating roller 4 and the second agitating roller 5. In addition, when the first agitating roller 4 and the second agitating roller 5 encounter hard, hard, and compacted materials,This design allows for a speed difference between the fixed wheel 7, the first rotating wheel 8, and the second rotating wheel 9, preventing jamming.

[0017] like Figure 2 As shown, the first agitator roller 4 is provided with several first protrusions 10 for adhering to the outer peripheral wall of the second agitator roller 5, and the second agitator roller 5 is provided with several second protrusions 11 for adhering to the outer peripheral wall of the first agitator roller 4. When the clumped material is drawn into the first agitator roller 4 and the second agitator roller 5, the first protrusions 10 can squeeze the clumped material toward the outer peripheral wall of the second agitator roller 5, while the second protrusions 11 can squeeze the clumped material toward the outer peripheral wall of the first agitator roller 4. This causes the clumped material to be squeezed and broken up under the force of the first protrusions 10 or the second protrusions 11, thus better ensuring the agitator roller 4 and the second agitator roller 5 work together. The dispersing roller 5 effectively breaks up agglomerated materials. The centerline of the second protruding block 11 is located between the two first protruding blocks 10. This arrangement ensures that the first and second dispersing rollers 4 and 5 do not interfere with each other during operation, guaranteeing their operational stability. Furthermore, when installing the first and second dispersing rollers 4 and 5, operators do not need to spend time preventing interference between the first and second protruding blocks 10 and 11, making installation more convenient. The spacing between adjacent first protruding blocks 10 and adjacent second protruding blocks 11... The first protruding block 10 and the second protruding block 11 are equally spaced, and have the same shape. The distance between adjacent first protruding blocks 10 is at least three times the length of the first protruding block 10. This arrangement ensures that there is always a gap between the first protruding block 10 and the second protruding block 11. This arrangement allows the material to leak out along the gap between the first protruding block 10 and the second protruding block 11 when the clumped material is squeezed and broken up by the first protruding block 10 or the second protruding block 11, preventing the broken material from being forcibly squeezed onto the outer peripheral wall of the first mixing roller 4 or the second mixing roller 5, and reducing the possibility of wear on the surface of the first mixing roller 4 or the second mixing roller 5. Block 10 is shaped like a frustum. The area at the connection between the first protruding block 10 and the outer peripheral wall of the first stirring roller 4 is larger than the surface area of ​​the first protruding block 10 facing away from the first stirring roller 4. This arrangement makes it easier for stress concentration to form on the smaller surface area when the first protruding block 10 presses the clumped material against the outer peripheral wall of the second stirring roller 5. This allows the first protruding block 10 to more easily squeeze and break up the clumped material, ensuring the dispersing effect of the first protruding block 10 on the clumped material. Similarly, the second protruding block 11 also adopts the above arrangement, which can better ensure the squeezing and dispersing effect of the stirring device on the clumped material and improve the stirring efficiency of the stirring device on the raw materials. Example

[0018] Pigment reaction vessel, such as Figure 1As shown, the stirring device mentioned in Embodiment 1 includes a vessel body 12. A drive motor 13 is provided at the bottom of the vessel body 12. The length direction of the rotating shaft 1 coincides with the height direction of the vessel body 12. The end of the rotating shaft 1 is fixedly connected to the drive motor 13. The synchronous rotation of the rotating shaft 1, the first stirring roller 4, and the second stirring roller 5 can be achieved by a single drive motor 13, improving the linkage efficiency of the stirring device. A mechanical seal device is installed on the part of the rotating shaft 1 that passes through the vessel body 12. An axial double-end mechanical seal device is preferred to reduce the leakage of raw materials from the vessel body during the operation of the stirring device. To mitigate the possibility of leakage in reactor 12, the top surface of the fixing rod 6 is fixedly connected to the inner wall of reactor 12 with screws. Installing the drive motor 13 at the bottom of reactor 12 can lower the overall center of gravity of the reactor and improve the stability of the reactor during operation. At the same time, it can also ensure the convenience of maintenance of drive motor 13 in case of failure. Reactor 12 is made of stainless steel, which has excellent corrosion resistance. Reactor 12 made of stainless steel can better adapt to working environments that are in contact with raw materials for a long time, thereby ensuring the service life of reactor 12.
