Description

Technical Field

[0001] This application relates to the technical field of ceramic pigment preparation, and in particular to an integrated method for ceramic pigment stirring and cooling. Background Technology

[0002] Ceramic pigments typically require stirring, dispersion, and cooling during preparation to ensure uniform dispersion of pigment particles in the slurry and stability of subsequent sintering and coloring. In existing technologies, continuous stirring combined with jacket cooling or circulating cooling is often used to treat ceramic pigment slurries. Continuous stirring prevents particle sedimentation, and external cooling lowers the slurry temperature.

[0003] However, in actual processing, ceramic pigment slurries usually have high solid content and strong viscosity. The slurry is prone to local heat accumulation due to continuous shearing. Traditional cooling methods mostly rely on constant temperature control based on the overall temperature, lacking dynamic adjustment of the relationship between the heat diffusion state and particle dispersion state inside the slurry. This leads to problems such as lag in heat conduction, increased local temperature difference, and particle re-agglomeration inside the slurry.

[0004] Especially under high shear stirring conditions, the changes in the flow field inside the slurry and the thermal diffusion process have obvious asynchronous characteristics. When the cooling effect is not matched with the dispersion state of the slurry particles, local overcooling, abnormal increase in slurry viscosity and secondary agglomeration of particles are likely to occur. This not only reduces the uniformity of ceramic colorant slurry dispersion, but also affects the coloring stability and product quality consistency in the subsequent sintering process. Summary of the Invention

[0005] The purpose of this application is to provide an integrated method for mixing and cooling ceramic pigments to solve the problems in the prior art.

[0006] This application provides a method for integrating ceramic pigment stirring and cooling, which employs the following technical solution: including the following steps; S1. Ceramic pigment, dispersion medium and additives are mixed to form ceramic pigment slurry. The ceramic pigment slurry is circulated and sheared and stirred. Torque change parameters, flow field fluctuation parameters, slurry temperature parameters, slurry viscosity parameters and local temperature difference parameters of slurry are collected in real time during the stirring process. S2. Perform periodic analysis on the collected torque variation parameters, flow field fluctuation parameters and slurry viscosity parameters to establish a slurry shear phase model. The shear phase model is used to characterize the particle dispersion state, shear energy transfer state and slurry flow stability state inside the slurry. S3. Perform thermal response analysis on the collected slurry temperature parameters and local temperature difference parameters to establish a slurry thermal diffusion phase model. The thermal diffusion phase model is used to characterize the internal heat diffusion state, local heat accumulation state, and heat conduction lag state of the slurry. S4. Calculate the thermal-shear phase shift based on the shear phase model and the thermal diffusion phase model, and identify the heat accumulation interval, shear instability interval and particle agglomeration risk interval inside the slurry according to the phase shift. S5. When the phase offset reaches the preset coupling threshold, pulse cooling control is performed on the slurry so that the cooling effect is applied to the slurry intermittently according to the preset pulse period and preset time window, so as to complete the heat removal before the slurry particles agglomerate for the second time. S6. During the pulse cooling process, the shear frequency, cooling pulse cycle, single cooling duration and cooling intensity of the slurry are dynamically adjusted according to the amplitude of the temperature gradient change, torque fluctuation amplitude, slurry viscosity change rate and thermal diffusion lag time, so as to keep the thermal diffusion rate and particle dispersion rate of the slurry in a synchronous coupled state. S7. Dynamically predict the agglomeration trend of particles inside the slurry. When a sudden increase in slurry torque, abnormal increase in viscosity and delayed local temperature recovery are detected at the same time, it is determined that the slurry has entered the critical state of particle agglomeration, and the cooling frequency and shear energy input intensity are increased in advance. S8. When the temperature fluctuation range inside the slurry is lower than the preset temperature difference threshold, the viscosity change rate of the slurry is lower than the preset stability threshold, and the particle agglomeration risk index is lower than the preset risk threshold, the ceramic pigment slurry is subjected to coordinated stirring and cooling treatment through an integrated stirring structure.

[0007] Preferably, the integrated stirring structure includes a turntable, a drive shaft, a first main water pipe, fins, and a second main water pipe. A set of drive shafts is provided at the top center of the turntable. A set of transition cavities is provided at both the left and right ends of the turntable. The two sets of transition cavities are respectively connected to an inlet and an outlet. The bottom ends of the two sets of transition cavities are connected to the left and right ends of the top surface of the first main water pipe. A heat-conducting layer is provided inside the first main water pipe. The outer end of the first main water pipe is connected to at least two sets of fins through a connecting port. The ends of the fins on the left and right sides that are far apart from each other are connected through the second main water pipe. A heat-conducting layer is provided inside the second main water pipe.

[0008] By adopting the above technical solution, when the drive shaft drives the turntable to rotate, the main water pipe one, the fins and the main water pipe two can simultaneously serve as stirring blades and cooling channels, realizing the integration of stirring and cooling, saving equipment space and avoiding interference from independent cooling coils with the flow field; the cooling water forms a circulating water path through the inlet, transition chamber, main water pipe one, connecting port one, fins, main water pipe two and outlet, which, together with the heat-conducting layer one and heat-conducting layer three, enhances heat exchange, greatly improving cooling efficiency and stirring and dispersion effect.

[0009] Preferably, each of the fins has a cooling cavity at its inner end, and each cooling cavity has a set of connecting ports at both the left and right ends, and each cooling cavity has a heat-conducting layer.

[0010] By adopting the above technical solution, the cooling chamber can accommodate the flow of cooling water, and the two connecting ports at both ends enable communication with the main water pipe and the main water pipe, allowing the fins to exchange heat internally while being stirred and sheared. The heat-conducting layer can enhance the heat conduction performance of the fins and further improve the cooling heat exchange efficiency.

[0011] Preferably, the torque variation parameters include at least one of torque peak value, torque fluctuation frequency, torque periodic change rate, and torque transient fluctuation amplitude, and the flow field fluctuation parameters include at least one of slurry vortex change period, flow velocity fluctuation frequency, local backflow period, and shear layer change frequency.

[0012] By adopting the above technical solution and collecting multi-dimensional torque change parameters and flow field fluctuation parameters, it is possible to accurately capture the dynamic changes of particle aggregation and dispersion states inside the slurry from multiple time scales, providing high-resolution basic data for the subsequent establishment of shear phase models. It is also possible to quantitatively characterize the periodic evolution law of the slurry flow structure, effectively identify the trend of declining shear energy transfer efficiency, and help predict the risk of particle re-aggregation caused by flow field turbulence.

[0013] Preferably, the shear phase model is established by the correlation between the peak occurrence period of the slurry torque, the flow field fluctuation period, and the slurry viscosity fluctuation period, and the periodic variation trend is used to characterize the dispersion stability of slurry particles.

[0014] By adopting the above technical solutions, a dual-phase model is established based on the mechanical properties and thermal response properties of the slurry. This model can accurately characterize the particle dispersion stability through the coupled analysis of multiple periodic parameters, effectively avoiding misjudgments caused by fluctuations in a single parameter. It can also quantify the heat transfer process inside the slurry as phase characteristics, clearly revealing the temporal differences between thermal diffusion and shear heat generation, and providing a reliable early warning for the risk of heat accumulation.

[0015] Preferably, the thermal-shear phase offset is the time difference between the occurrence time of the shear phase peak and the occurrence time of the thermal diffusion phase peak, or it is the periodic offset angle between the shear phase curve and the thermal diffusion phase curve.

[0016] By adopting the above technical solution, two quantitative evaluation indicators are provided. When the phase offset continues to increase and exceeds the preset coupling threshold, the risk of heat accumulation and particle agglomeration can be accurately determined, triggering subsequent pulse cooling.

[0017] Preferably, the particle agglomeration risk range is determined by at least two of the following parameters: increased slurry torque fluctuation amplitude, increased slurry viscosity growth rate, prolonged local temperature rise recovery time, and increased thermal diffusion lag time.

[0018] By adopting the above technical solution and using multi-parameter joint logic thresholds, the robustness of cluster risk identification is significantly improved, and false triggering caused by single-parameter noise is avoided.

[0019] Preferably, the pulsed cooling control includes a cooling start-up phase, a continuous cooling phase, and a cooling intermittent phase, and the cooling start-up time is synchronized with or lags behind the occurrence time of the shear phase peak by 0.2 to 3 seconds.

[0020] By adopting the above technical solution, heat can be efficiently removed during the window period when shearing is most intense, which not only prevents premature cooling from affecting dispersion efficiency, but also avoids secondary agglomeration caused by late cooling.

[0021] Preferably, when dynamically adjusting the cooling pulse cycle, if the slurry thermal diffusion lag time is detected to be prolonged and the local temperature difference is increased, the cooling interval time is shortened and the cooling frequency is increased.

[0022] By adopting the above technical solution, real-time matching between cooling frequency and heat diffusion requirements is achieved. When heat diffusion lags and the risk of agglomeration increases, the cooling frequency is automatically increased to maintain heat-shear synchronization.

[0023] Preferably, the synchronous coupling state is characterized by the deviation between the thermal diffusion rate and the particle dispersion rate inside the slurry being less than a preset coupling error threshold, and the temperature gradient change rate inside the slurry maintaining a stable fluctuation state.

[0024] By adopting the above technical solution, clear and quantifiable termination conditions are given, ensuring that the deviation between the internal thermal diffusion rate and particle dispersion rate of the slurry is within the allowable range at the end of the treatment, thereby improving the dispersion uniformity of the final slurry and the stability of subsequent sintering and coloring.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. This application establishes a slurry shear phase model and a thermal diffusion phase model, and calculates the thermal-shear phase offset in real time. When the offset reaches a preset coupling threshold, pulse cooling control is performed on the slurry, so that the cooling start time is synchronized with or delayed by 0.2 to 3 seconds from the occurrence of the shear phase peak. Compared with the continuous constant cooling method used in the prior art, this intermittent pulse cooling can accurately match the energy demand cycle of slurry particle dispersion, complete the heat removal before the particles re-agglomerate, avoid the problem of reduced slurry fluidity caused by over-cooling, and reduce the consumption of cooling medium and energy loss, thereby improving the targeting and economy of the cooling process. 2. This application dynamically monitors the amplitude of temperature gradient change, torque fluctuation amplitude, viscosity change rate, and thermal diffusion lag time within the slurry, and adjusts the slurry shear frequency, cooling pulse cycle, single cooling duration, and cooling intensity in real time. When a sudden increase in torque, abnormal increase in viscosity, and local temperature rise recovery delay are detected simultaneously, the cooling frequency and shear energy input intensity are increased in advance. Compared with the existing technology that uses a fixed stirring speed and cooling power, this synergistic adjustment mechanism can keep the thermal diffusion rate and particle dispersion rate in a synchronous coupled state, significantly suppressing the evolution of the critical state of particle agglomeration, improving the long-term dispersion stability of ceramic pigment slurry and the consistency of subsequent sintering and coloring. 3. This application forms a multi-stage circulating cooling flow path by setting a "U"-shaped main water pipe 3 at the bottom of the turntable 1, fins 4 connected to the left and right sides of the main water pipe 3, and main water pipes 5 located at both ends of the fins 4. Combined with the heat-conducting layer 31 inside the main water pipe 3 and the heat-conducting layer 43 inside the fins 4, the heat exchange efficiency between the cooling liquid and the slurry is significantly improved. Compared with the existing technology that uses a single cooling jacket or coil, this structure can avoid the generation of cooling dead zones, so that heat can be quickly conducted from the inside of the slurry to the cooling medium, effectively reducing the phenomenon of local heat retention, thereby reducing the secondary agglomeration of ceramic pigment particles due to long-term residence at high temperature, and improving the uniformity of the temperature field of the slurry.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0029] This embodiment provides an integrated method for mixing and cooling ceramic pigments, referring to... Figure 1 It is used to reduce the secondary agglomeration of ceramic pigment slurry particles during the stirring and cooling process, and to improve the dispersion uniformity and temperature stability of the slurry.

[0030] In this embodiment, an iron oxide ceramic pigment slurry is used as an example. The ceramic pigment slurry includes iron oxide pigment powder, deionized water and dispersing agent, wherein the iron oxide pigment powder accounts for 35-55% by mass and the dispersing agent accounts for 0.5-3% by mass.

[0031] First, ceramic pigment powder, dispersant, and deionized water are mixed to form an initial slurry, which is then subjected to cyclic shearing and stirring. During the stirring process, parameters such as slurry torque variation, flow field fluctuation, slurry temperature, slurry viscosity, and local temperature difference are collected in real time.

[0032] Among them, torque variation parameters include peak torque, torque fluctuation frequency, and transient torque variation amplitude; flow field fluctuation parameters include the vortex variation period inside the slurry, local backflow period, and shear layer fluctuation frequency; slurry temperature parameters include the average slurry temperature, local high-temperature region temperature, and temperature change rate; and slurry local temperature difference parameters include the temperature gradient variation value between different regions of the slurry.

[0033] Subsequently, periodic analysis was performed on the collected torque variation parameters, flow field fluctuation parameters, and slurry viscosity parameters, and a slurry shear phase model was established. Specifically, based on the correlation between the time of torque peak occurrence, the flow field vortex formation period, and the slurry viscosity fluctuation period, a shear phase curve was generated to characterize the particle dispersion state inside the slurry.

[0034] Simultaneously, thermal response analysis was performed on the slurry temperature parameters and local temperature difference parameters. Based on the slurry temperature change rate, thermal diffusion lag time, and local temperature rise recovery time, a thermal diffusion phase model was established to form the slurry thermal diffusion phase curve.

[0035] Furthermore, the shear phase curve and the thermal diffusion phase curve are analyzed simultaneously to calculate the thermal-shear phase shift between them. The phase shift is the time difference between the occurrence time of the shear phase peak and the occurrence time of the thermal diffusion phase peak, or the periodic offset angle between the two phase curves.

[0036] In this embodiment, when the phase offset is detected to be continuously increasing and exceeding a preset coupling threshold, it is determined that there is a tendency for heat accumulation and a risk of particle agglomeration inside the slurry. At this time, pulsed cooling control is performed on the slurry.

[0037] The pulsed cooling control applies cooling intermittently according to a preset time window, with a single cooling duration of 1 to 5 seconds and an adjacent cooling interval of 0.5 to 3 seconds. The cooling start time is synchronized with or delayed by 0.2 to 3 seconds from the occurrence of the shear phase peak, so as to complete the heat removal before the slurry particles re-agglomerate.

[0038] During the cooling process, the slurry shear frequency, cooling pulse period, and cooling intensity are dynamically adjusted based on the amplitude of the temperature gradient change inside the slurry, the amplitude of torque fluctuation, the slurry viscosity change rate, and the thermal diffusion hysteresis time.

[0039] Specifically, when an increase in local temperature difference and viscosity growth rate is detected in the slurry, the shear frequency is increased and the cooling interval is shortened to enhance the heat diffusion efficiency and particle dispersion ability inside the slurry; when the temperature fluctuation inside the slurry is detected to be stable, the cooling frequency is reduced to avoid excessive cooling that would reduce the fluidity of the slurry.

[0040] Furthermore, the agglomeration trend of slurry particles is dynamically predicted. When a sudden increase in slurry torque, an abnormal increase in slurry viscosity, and a prolonged local temperature rise recovery time are detected simultaneously, the slurry is determined to have entered a critical state of particle agglomeration. The cooling frequency and shear energy input intensity are increased in advance to inhibit secondary particle agglomeration.

[0041] Finally, when the temperature fluctuation inside the slurry is lower than the preset temperature difference threshold, the viscosity change rate of the slurry is lower than the preset stability threshold, and the particle agglomeration risk index is lower than the preset risk threshold, the integrated stirring structure completes the synergistic stirring and cooling treatment of the ceramic pigment slurry.

[0042] By adopting the above method, the thermal diffusion process inside the slurry and the particle dispersion process can be kept in a synchronous coupled state, thereby reducing the phenomenon of local heat accumulation, reducing the secondary agglomeration of ceramic pigment particles, and improving the dispersion uniformity of ceramic pigment slurry and the stability of subsequent sintering and coloring.

[0043] A method for integrating ceramic pigment mixing and cooling, referring to Figures 2-3The system includes a turntable 1, a drive shaft 2, a first main water pipe 3, fins 4, and a second main water pipe 5. A drive shaft 2 is located at the top center of the turntable 1, and is connected to an external transmission device via the drive shaft 2. This drive shaft 2 drives the turntable 1 to rotate reciprocally, achieving a mixing effect on the materials. A U-shaped first main water pipe 3 is located at the bottom of the turntable 1. Each end of the first main water pipe 3 has at least two sets of fins 4. When the turntable 1 rotates, the U-shaped first main water pipe 3 drives the fins 4 at both ends to rotate synchronously, enhancing the mixing effect on the materials. The ends of the fins 4 on both sides that are far apart are connected by the main water pipe 2 5 to ensure the flow effect of the cooling liquid. The turntable 1 has transition chambers 11 at both ends. The bottom ends of the two sets of transition chambers 11 are connected to the top ends of the "U"-shaped main water pipe 1 3 respectively. The left end of the transition chamber 11 has a set of inlet 12 on the left side and the right end of the transition chamber 11 has a set of outlet 13 on the right side. The cooling liquid can enter the main water pipe 1 3 through the inlet 12 and then be discharged through the outlet 13, realizing the flow cooling of the cooling liquid and carrying away the heat.

[0044] A method for integrating ceramic pigment mixing and cooling, referring to Figure 3 The inner side of the main water pipe 3 is covered with a heat-conducting layer 31, which is a high heat-conducting layer made of copper foil or aluminum film, which can effectively improve the heat conduction and cooling effect. The inner end of the main water pipe 3 is provided with a corresponding connecting port 32 for the fin 4, and the cooling liquid can enter the fin 4 through the connecting port 32.

[0045] A method for integrating ceramic pigment mixing and cooling, referring to Figure 2 and Figure 4 The main water pipe 3 has at least two sets of fins 4 connected to both sides. The fins 4 are installed at an angle on both sides of the main water pipe 3, which can improve the stirring effect on the material during rotation. The inner end of each fin 4 is provided with a cooling chamber 41. The left and right ends of the cooling chamber 41 are provided with a set of connecting ports 42. The left and right connecting ports 42 are connected to the main water pipe 3 and the main water pipe 5 respectively, which can realize the efficient flow of cooling liquid and avoid dead corners to ensure the cooling effect on the material. The inner side of the cooling chamber 41 is provided with a heat-conducting layer 43. The heat-conducting layer 43 is made of the same material as the heat-conducting layer 31, which is a high heat-conducting layer, which can effectively ensure the cooling effect.

[0046] A method for integrating ceramic pigment mixing and cooling, referring to Figure 2 and Figure 5 Each of the two fins 4 on the left and right sides is provided with a set of main water pipes 2 5 at the ends that are far apart from each other. The main water pipes 2 5 are connected to the main water pipes 2 5 through the connecting port 2 42, so that the cooling liquid can flow into the main water pipes 2 5 to enhance the cooling effect. At the same time, the main water pipes 2 5 connect and reinforce the fins 4 on the left and right sides to prevent the fins 4 from shifting or misaligning during the rotation and stirring process.

[0047] This application provides an integrated method for mixing and cooling ceramic pigments. By establishing a shear phase model and a thermal diffusion phase model of the ceramic pigment slurry, and implementing synergistic control based on the thermal-shear phase shift relationship between the two, compared with traditional continuous mixing and constant cooling methods, it can dynamically identify the heat accumulation state and particle agglomeration trend inside the slurry, so that the cooling process and the particle dispersion process of the slurry are synchronously coupled. This reduces the secondary agglomeration of particles caused by local heat retention, improves the dispersion uniformity and stability of the ceramic pigment slurry, and adopts a pulsed cooling and dynamic shear synergistic adjustment mechanism. It can adjust the cooling frequency and shear energy input intensity in real time according to the slurry temperature gradient, viscosity change and thermal diffusion hysteresis state, avoiding the problems of local overcooling, decreased slurry fluidity and reduced dispersion efficiency caused by traditional continuous cooling. This further improves the heat exchange efficiency and temperature field uniformity of the slurry, reduces energy loss, and improves the consistency of subsequent sintering and coloring of ceramic pigments and the stability of product quality.
