Description

Technical Field

[0001] The utility model relates to a temperature-raising emulsifying device, an emulsifying machine and a dispersing machine, and belongs to the technical field of liquid material dispersion. Background Art

[0002] During the production of liquid materials such as dyes, pesticides, and inks, high-speed stirring and mixing devices such as dispersers are used to mix and blend the liquid materials with immiscible solvents. In actual production, the mixed liquid also needs to be heated in stages, stirred while heated, and other operations as different materials are added or the stirring process requires. Existing dispersers have limited dispersing capabilities. When the particle size of the liquid material is reduced to a certain size after dispersion (0.8-0.9mm measured in production), it can no longer be further dispersed by traditional dispersers. At this point, an emulsifier is required to further break up the liquid material before dispersing and mixing it. Therefore, in order to meet the production process requirements for the dispersion and emulsification of the aforementioned liquid materials, the disperser is often required to be equipped with multiple functional systems such as a dispersion mechanism, a stirring mechanism, an emulsifying mechanism, and a heating system. This results in a complex structure for the disperser itself, high cost, and high energy consumption. Furthermore, to achieve optimal emulsification and dispersion, existing emulsifiers incorporate a complex emulsification channel structure formed by the stator and rotor. This leads to complex stator and rotor structures, high assembly precision requirements, high costs, and a high failure rate. Furthermore, the complex emulsification channel reduces the flow rate of the liquid through the channel, affecting emulsification efficiency. Therefore, there is an urgent need for an emulsification device and emulsification dispersion agitator with a simple structure, low cost, low failure rate, and low energy consumption. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a temperature-raising emulsifying device and an emulsifying dispersion stirring tank. The stator and the rotor of the emulsifying device are matched to form a temperature-raising effect during the emulsification process, which not only meets the emulsification and dispersion requirements but also realizes the heating and temperature-raising function, so that the dispersing machine can be equipped with a heating system. The overall structure of the emulsifying device and the dispersing machine is simple, the cost is low, the emulsification efficiency is high, the failure rate is low, and the energy consumption is low.

[0004] The purpose of this utility model is achieved in this way:

[0005] A temperature-raising emulsification device comprises a stator and a rotor arranged in a nested manner, wherein the stator comprises a first annular wall and a first connecting member arranged in the first annular wall; the rotor comprises a second annular wall and a second connecting member arranged in the second annular wall; the second annular wall is nested in the first annular wall;

[0007] Furthermore, the first annular wall and the second annular wall are assembled with a gap, and the gap between the two is 0.4-0.5 mm.

[0008] Furthermore, the number of the inclined opening slots and the number of the vertical opening slots are both 36.

[0009] Furthermore, the inclined angle α between the inclined opening groove and the horizontal plane is 60-70 degrees.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The temperature-raising emulsification device of the utility model forms a shear channel with a specific channel area and channel shape that changes periodically by providing vertical opening slots and inclined opening slots between the rotor and the stator, and controlling the set gap between the two. Relying on a high relative speed, the device produces shearing, squeezing, cutting, and friction effects on the liquid material, thereby further refining, dispersing, and emulsifying the liquid material. The shear channel has a simple structure and a short path, resulting in a fast liquid passage speed and a large flow rate, high emulsification and dispersion processing efficiency, low cost, low failure rate, and low energy consumption. At the same time, an additional temperature-raising effect is generated in the process, which can effectively meet the heating requirements during the emulsification and dispersion processing.

The measured heating rate can meet the heating requirements of the liquid material emulsification and dispersion process. Therefore, there is no need to add an additional heating system, which simplifies the disperser structure, reduces equipment cost, improves emulsification and dispersion efficiency, reduces failure rate, and reduces operating costs.

[0036] A stirring tank 100 , a disperser 200 , a mixer 300 , and an emulsifier 400 . DETAILED DESCRIPTION Example 1:

[0037] See also Figures 1 to 11 The present invention relates to a temperature-raising emulsifying device, comprising a nested stator 1 and a rotor 2. The stator 1 comprises a first annular wall 11 and a first connecting member 12 disposed within the first annular wall 11; the rotor 2 comprises a second annular wall 21 and a second connecting member 22 disposed within the second annular wall 21; the second annular wall 21 is nested within the first annular wall 11, and the two are assembled with a gap, and the gap control range is 0.4-0.5 mm, that is, the gap between the stator 1 and the rotor 2;

[0038] The stator 1 is fixedly mounted on the tripod 4 via a first connecting member 12 and a small pull rod 3; a main shaft 5 is rotatably provided in a coaxial central through hole of the first connecting member 12 and the tripod 4, and an impeller 6 for enhancing the upward and downward convection of the liquid is fixedly mounted on the main shaft 5; the rotor 2 is fixedly mounted on the lower end of the main shaft 5 via a second connecting member 22 and rotates with the main shaft 5; the first connecting member 12 and the second connecting member 22 are both three-arm hollow structures, which ensure the smooth flow of liquid above and below the stator 1 and the rotor 2. At the same time, the impeller 6 diverts liquid from other areas into the stator 1 and the rotor 2, further increasing the flow rate of liquid flowing through the stator 1 and the rotor 2, and improving the emulsification and dispersion efficiency;

[0039] A rotational lubrication mechanism is provided between the spindle 5 and the tripod 4, comprising a bearing sleeve 51 sleeved on the spindle 5, a lubrication seat 52 fixedly mounted on the tripod 4, a lubrication sleeve 53 nested between the bearing sleeve 51 and the lubrication seat 52, and a pressure plate 54 fixedly mounted on the top of the lubrication seat 52 for pressing the lubrication sleeve 53. The lubrication seat 52, the lubrication sleeve 53, and the pressure plate 54 are all made of polytetrafluoroethylene.

[0040] Polytetrafluoroethylene, also known as Teflon, commonly known as the "King of Plastics", has excellent heat and cold resistance, can be used for a long time at -180 to 260ºC, is resistant to acids and alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene is resistant to high temperatures, and its friction coefficient is extremely low, making it an excellent lubricating material. This embodiment uses a rotating lubrication mechanism with polytetrafluoroethylene as the main lubricating material. Compared with traditional lubrication support mechanisms such as ball bearings and copper bearing sleeves, it has lower friction resistance, more stable support performance, better corrosion resistance, and a longer service life. It is more suitable for use in corrosive liquid environments, ensuring the stability of the main shaft 5 during high-speed rotation, thereby ensuring that the gap between the first annular wall 11 and the second annular wall 21 is always in a stable state during high-speed relative rotation;

[0041] The first annular wall 11 is evenly provided with a plurality of inclined opening grooves 13, and the inclination angle of the inclined opening grooves 13 to the horizontal plane is α, which is 60-70 degrees; the second annular wall 21 is evenly provided with a plurality of vertical opening grooves 23, and the vertical opening grooves 23 are perpendicular to the horizontal plane; the groove depth of the inclined opening grooves 13 is greater than the groove depth of the vertical opening grooves 23;

[0042] In this embodiment, for the paint emulsification and dispersion process, the number of the inclined opening slots 13 and the vertical opening slots 23 are both set to 36, the slot width a of the two opening slots is both set to 8 mm, and the rotor speed is 2800 rpm, respectively:

[0043] Working condition A, the tilt angle α is 65 degrees, the gap between rotor 2 and stator 1 is 0.4mm,

[0044] Working condition B, the tilt angle α is 75 degrees, the gap between rotor 2 and stator 1 is 0.5mm,

[0045] Emulsification and dispersion treatment was carried out under two working conditions, and the temperature rise during the process is shown in Table 1;

[0047]

[0048] Between the high-speed rotating rotor 2 and the stator 1, the inclined opening slots 13 and the vertical opening slots 23 cooperate to periodically generate an emulsified shear channel with a periodic change in channel area and channel shape. Figure 11 , the liquid in the inner cavity of the rotor 2 is thrown out to the outer ring of the stator 1 through the shear channel. In the shear channel, large-sized droplets are cut, impacted, and squeezed in multiple directions by the inclined opening grooves 13 and the vertical opening grooves 23 and broken into small-sized droplets. The paint droplets of 0.8~0.9mm in size that cannot be further dispersed and refined are sucked into the inner ring of the rotor 2. Under the centrifugal force of the high-speed rotation of the rotor 2, the droplets are sucked into the shear channel and further broken and refined. At the same time, in the shear channel where the area and shape of the channel change periodically, large-sized droplets are broken into a large number of small-sized droplets. The rotor 2, the droplets, and the stator 1 produce shearing, squeezing, cutting, friction and other interactions, which produce a significant temperature increase effect of 60~90℃ / h, thereby further accelerating the mixing speed and achieving the effect of rapid homogenization and emulsification.

[0049] The temperature-raising emulsification device of the present invention forms a shear channel with a specific channel area and channel shape that changes periodically by providing the vertical opening slots 23 and the inclined opening slots 13 between the rotor 2 and the stator 1, and controlling the set gap between the two. Relying on a high relative speed, the device produces shearing, squeezing, cutting, and friction effects on the liquid material, so that the liquid material is further refined, dispersed, and emulsified. The shear channel has a simple structure and a short path, and the liquid passes through at a fast speed and a large flow rate, resulting in high emulsification and dispersion processing efficiency, low cost, low failure rate, and low energy consumption. At the same time, an additional temperature-raising effect is generated in the process, which can effectively meet the heating requirements during the emulsification and dispersion processing. Example 2:

[0050] See also Figure 12 The utility model relates to an emulsifying machine, comprising an emulsifying motor 7, a bearing box 8 and an emulsifying frame 9, on which the temperature-raising emulsifying device of the above-mentioned embodiment 1 is installed; the tripod 4 is fixedly mounted on the bottom of the emulsifying frame 9; the main shaft 8 is connected to the driving shaft of the emulsifying motor 7 through the bearing box 8 and the coupling;

[0051] The emulsifying machine of the present invention adopts the temperature-raising emulsifying device with additional temperature-raising capability in Example 1, which has an additional temperature-raising effect when emulsifying and dispersing liquid materials, does not require additional auxiliary heating, has a simple structure, low cost, high emulsification efficiency, low failure rate and low energy consumption. Example 3:

[0052] See also Figure 13The present invention relates to a disperser comprising a stirring tank 100, a disperser 200, and a stirrer 300, equipped with the emulsifier 400 of Example 2. Since the emulsifier 400 has an additional heating capacity for emulsifying the liquid material during the emulsification process, the measured heating rate can meet the heating requirements of the liquid material emulsification and dispersion process. Therefore, there is no need to add an additional heating system, which simplifies the disperser structure, reduces equipment cost, improves emulsification and dispersion efficiency, reduces equipment failure rate, and reduces operating costs.

[0053] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
