The uniformity of temperature directly affects the quality and production efficiency of the color fixing agent. In the traditional production process of color fixing agents, heaters or heating jackets are often used for heating.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0081] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0082] like Figure 1As shown, a temperature control device for color fixing agent production provided by the present invention comprises a high and low temperature circulation component 2, wherein the high and low temperature circulation component 2 comprises: a high and low temperature circulation integrated machine 201, a reactor 1 is arranged on one side of the high and low temperature circulation integrated machine 201, a jacket 204 is arranged on the reactor 1, a low temperature circulation pipeline 202 and a high temperature circulation pipeline 203 are connected between the jacket 204 and the high and low temperature circulation integrated machine 201, one end of the high temperature circulation pipeline 203 and the low temperature circulation pipeline 202 are respectively connected to the jacket 204, and the other end is respectively connected to the high and low temperature circulation integrated machine 201; the temperature control device for color fixing agent production also comprises:

[0083] A stirring component 3, which is arranged on one side of the reaction kettle 1 and is used to adjust the uniformity of the temperature of the color fixing agent mixed raw material in the reaction kettle 1;

[0084] A temperature monitoring module is used to monitor the temperature of the color fixing agent mixed raw material in the reaction kettle 1 in real time;

[0085] A temperature analysis unit, used to determine whether the temperature distribution is uniform according to a temperature evaluation value generated by the temperature in the reactor 1;

[0086] The adjustment analysis module generates a stirring speed adjustment value of the stirring component 3 according to the temperature evaluation value if the temperature distribution is uneven;

[0087] An adjustment module, used to control the stirring speed of the stirring component 3 according to the stirring speed adjustment value of the stirring component 3;

[0088] Specifically, by starting the high-low temperature cycle integrated machine 201, when the high-low temperature cycle integrated machine 201 generates high-temperature gas, the high-low temperature cycle integrated machine 201 transports the high-temperature gas to the jacket 204 through the high-temperature circulation pipeline 203 and performs gas circulation, and the high-temperature gas performs heat transfer through the jacket 204, and transfers the heat to the color fixing agent mixed raw material in the reactor 1, thereby completing the heating of the color fixing agent mixed pigment; conversely, when the high-low temperature cycle integrated machine 201 generates low-temperature gas, the high-low temperature cycle integrated machine 201 transports the low-temperature gas to the jacket 204 through the low-temperature circulation pipeline 202 and performs gas circulation, and the low-temperature gas performs heat transfer through the jacket 204, and absorbs the heat on the color fixing agent mixed raw material in the reactor 1, thereby completing the temperature control of the color fixing agent mixed pigment;

[0089] In this embodiment, the stirring component 3 is started by the motor, and the stirring component 3 makes the temperature distribution of the color fixing agent mixed raw material in the reactor 1 uniform; at the same time, the temperature of the color fixing agent mixed raw material in the reactor 1 is monitored by the temperature monitoring module, and then the temperature analysis unit is used to determine whether the temperature distribution of the color fixing agent mixed raw material in the reactor 1 is uniform. If the temperature distribution is not uniform, the stirring speed of the stirring component 3 is controlled according to the stirring speed adjustment value generated by the adjustment analysis module, so that the temperature distribution of the color fixing agent mixed raw material in the reactor 1 is uniform, while avoiding abnormal temperature increase caused by excessive rotation speed;

[0090] It should be noted that the rotation speed of the stirring assembly 3 will affect the reaction speed of the color fixing agent mixed raw material, and the change in the reaction speed will affect the heat absorption and release efficiency of the color fixing agent mixed raw material during the reaction process, thereby affecting the temperature of the color fixing agent mixed raw material.

[0091] like Figure 7 As shown, as a preferred embodiment of the present invention, the adjustment analysis unit specifically includes:

[0092] A data acquisition module, used to acquire bubble data, pressure value and stirring speed of the stirring component 3 in the reactor 1 through a sensor; wherein the bubble data includes bubble size and bubble quantity;

[0093] A data processing module, used to generate a bubble factor, a pressure factor and a friction factor according to the bubble data, the pressure value and the stirring speed of the stirring component 3 in the reaction kettle 1;

[0094] The stirring speed analysis module is used to establish an adjustment analysis model, substitute the bubble factor, pressure factor and friction factor into the adjustment analysis model, and generate a stirring speed adjustment value.

[0095] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, the stirring component specifically includes:

[0096] A stirring rod 301, wherein the stirring rod 301 is disposed in the reaction kettle 1, and one end of the stirring rod 301 is rotatably connected to the reaction kettle 1;

[0097] A stirring blade 302, wherein the stirring blade 302 is disposed at one end of the stirring rod 301 and is fixedly connected to the stirring rod 301;

[0098] A support shell 304, wherein the support shell 304 is disposed on one side of the reactor 1, and the support shell 304 is fixedly connected to the reactor 1;

[0099] A driving motor 303, wherein the driving motor 303 is disposed in the supporting shell 304, and the driving motor 303 is fixedly connected to the supporting shell 304;

[0100] A power connector 305, which is disposed between the support shell 304 and the stirring rod 301, wherein one end of the power connector 305 is fixedly connected to the output end of the driving motor 303, and the other end of the power connector 305 is snap-connected to the stirring rod 301 through a snap-in groove provided on the stirring rod 301;

[0101] Specifically, by starting the drive motor 303, the output end of the drive motor 303 drives the power connecting piece 305 to rotate, the power connecting piece 305 drives the stirring rod 301 to rotate through the clamping groove provided on the stirring rod 301, and the stirring rod 301 drives the stirring blade 302 to rotate, thereby achieving stirring of the color fixing agent mixed raw material in the reactor 1.

[0102] like Figure 3 As shown, as a preferred embodiment of the present invention, a temperature control device for color fixing agent production provided by the present invention further includes:

[0103] A pressure relief component 4, which is arranged on the outer wall of the reaction kettle 1 and is used to adjust the pressure value in the reaction kettle 1 to control the reaction state of the color fixing agent mixed raw material in the reaction kettle 1;

[0104] The pressure relief component 4 specifically includes:

[0105] A housing 401, wherein the housing 401 is fixedly disposed on one side of the reaction vessel 1;

[0106] A pressure relief valve 402, wherein the pressure relief valve 402 is disposed in the housing 401, and the pressure relief valve 402 is in contact with the inner wall of the housing 401;

[0107] A sliding member 403, wherein the sliding member 403 is disposed on one side of the pressure relief valve 402, one end of the sliding member 403 is fixedly connected to the pressure relief valve 402, and the other end of the sliding member 403 is slidably connected to the housing 401 via a sliding groove provided on the housing 401;

[0108] A pressure relief hole 404, wherein the pressure relief hole 404 is provided on the housing 401;

[0109] An elastic member 405, wherein the elastic member 405 is disposed on one side of the pressure relief valve 402, and the elastic member 405 is interlaced and connected with the sliding member 403;

[0110] Two groups of one-way flow holes 406, the two groups of one-way flow holes 406 are respectively opened on the reactor 1 and the shell 401 and are interconnected, and one end of the one-way flow hole 406 is in contact with the pressure relief valve 402;

[0111] A pressure relief hole 404, which is provided on the housing 401 and is used to release the fluid flowing out of the one-way flow hole 406;

[0112] Specifically, when the pressure in the reactor 1 is greater than the rated pressure, the gas in the reactor 1 will push the pressure relief valve 402 to perform linear movement, and the pressure relief valve 402 drives 403 to perform linear movement along the slide groove provided on the shell 401. At the same time, the pressure relief valve 402 will compress the elastic member 405 to deform the elastic member 405. At this time, the gas in the reactor 1 will flow into the shell 401 through the two sets of one-way flow holes 406 due to the pressure difference, and then flow to the outside of the reactor 1 through the pressure relief hole 404, so that the pressure in the reactor 1 can be automatically reduced when the pressure in the reactor 1 is too high, so as to prevent the excessive pressure in the reactor 1 from causing the endothermic and exothermic reaction of the color fixing agent mixed raw material in the reactor 1 to intensify, and finally causing the temperature of the color fixing agent mixed raw material in the reactor 1 to change abnormally.

[0113] It should be explained that the greater the pressure, the more intense the reaction between the raw materials. The more intense the reaction, the faster the heat absorption and release during the reaction, which causes abnormal changes in the temperature of the color fixing agent mixed raw materials in the reactor 1.

[0114] As a preferred embodiment of the present invention, the temperature monitoring module includes:

[0115] A plurality of sensors, some of which are arranged in the reactor 1, and are used to obtain the temperature of different areas of the color fixing agent mixed raw material in the reactor 1;

[0116] Specifically, the raw material solution in the reactor 1 is divided into several monitoring areas, and several sensors are respectively arranged in the corresponding areas; for example, the raw material solution is divided into a bottom monitoring area, a middle monitoring area and a high monitoring area according to the height.

[0117] like Figure 5 As shown, as a preferred embodiment of the present invention, the temperature analysis unit specifically includes:

[0118] The regional temperature difference analysis module is used to generate a temperature difference factor according to the temperature difference between different monitoring areas in the reactor 1;

[0122] As a preferred embodiment of the present invention, the method for obtaining the temperature difference factor specifically includes:

[0123] Perform absolute difference processing on the temperatures of adjacent monitoring areas to generate temperature difference values ​​of the monitoring areas;

[0124] The temperature difference value of the monitoring area is compared with the preset temperature difference value of the monitoring area to generate the temperature deviation value between adjacent monitoring areas; the preset temperature difference value of the monitoring area refers to the maximum temperature difference of the monitoring area that can be accepted by the fixing agent during the production process without affecting the production quality;

[0125] All temperature deviation values ​​are averaged to generate a temperature difference factor.

[0126] As a preferred embodiment of the present invention, the method for obtaining the variation factor specifically includes:

[0127] Perform difference processing on the current temperature of the monitoring area and the historical temperature value to generate the temperature fluctuation characteristic value;

[0128] It should be noted that the historical temperature value refers to the minimum value between the time node of the historical temperature value and the current time node;

[0129] The temperature fluctuation characteristic value and the nearest end point of the temperature fluctuation characteristic error range are processed by difference to generate the temperature fluctuation degree value; the temperature fluctuation characteristic error range refers to the standard range of temperature change values ​​of the fixing agent in the standard production process, and this range will not affect the production quality of the fixing agent;

[0130] The temperature fluctuation values ​​of all monitoring areas are averaged to generate a variation factor;

[0131] It should be noted that the heat absorption and release phenomenon generated by the reaction of the color fixing agent mixed raw material will cause abnormal temperature changes of the color fixing agent mixed raw material, thereby aggravating the uneven temperature distribution phenomenon.

[0132] As a preferred embodiment of the present invention, the temperature evaluation value is generated in the following manner:

[0133] Establish a temperature assessment model, substitute the temperature difference factor and the change factor into the temperature assessment model, and generate a temperature assessment value C0;

[0134] Among them, the expression of the temperature evaluation model is:

[0135] C0=C1*ca+C2*cb;

[0136] In the expression, C1 represents the temperature difference factor, C2 represents the change factor, ca and cb are both proportional coefficients, and ca+cb=1.

[0137] like Figure 6 As shown, as a preferred embodiment of the present invention, the determination method of the temperature determination module is:

[0138] The temperature evaluation value C0 is compared with the temperature evaluation threshold. If the temperature evaluation value C0 is less than or equal to the temperature evaluation threshold, it means that the smaller the temperature evaluation value C0 is, the more uniform the temperature of the solution in the reactor 1 is, and there is no temperature non-uniformity.

[0139] If the temperature evaluation value C0 is greater than the temperature evaluation threshold, it means that the larger the temperature evaluation value C0 is, the more uneven the temperature of the solution in the reactor 1 is, and the temperature is uneven;

[0140] It should be explained that the method for obtaining the temperature evaluation threshold is the same as the method for obtaining the temperature evaluation value C0, which will not be repeated here, and the value is set by the user.

[0141] As a preferred embodiment of the present invention, the stirring speed adjustment value is generated in the following manner:

[0142] Establish an adjustment analysis model, substitute the bubble factor, pressure factor and friction factor into the adjustment analysis model, and generate a stirring speed adjustment value ΔS;

[0143] Among them, the expression of adjusting the analysis model is:

[0144]

[0145] In the expression, C0 represents the temperature evaluation value, M represents the bubble factor, F represents the pressure factor, S0 represents the current stirring speed, Q represents the friction factor, and α, β, and γ are all proportional coefficients.

[0146] As a preferred embodiment of the present invention, the bubble factor is obtained in the following manner:

[0147] Acquire bubble data in the reactor 1; wherein the bubble data includes the number of bubbles and the size of the bubbles;

[0148] The method of obtaining the bubble data includes but is not limited to setting an image sensor in the reactor 1, obtaining an image through the image sensor, and obtaining the bubble data according to the image;

[0149] The number of bubbles is processed by subtracting the number of bubbles generated by the normal reaction of the color fixing agent to generate the difference in the number of bubbles;

[0150] Then the difference in the number of bubbles is compared with the number of bubbles generated by the normal reaction of the fixing agent to generate an evaluation value of the number of bubbles;

[0151] The bubble size is processed by subtracting the bubble size from the size of the bubble generated by the normal reaction of the color fixing agent to generate the bubble size difference;

[0152] Then the bubble size difference is compared with the size of bubbles generated by the normal reaction of the fixing agent to generate a bubble size evaluation value;

[0153] It should be explained that during the mixing and stirring process of the color fixing agent and the raw materials, the mixing of the raw materials will generate a certain amount of gas, which will rise to generate bubbles; in addition, the number of bubbles generated by the normal reaction of the color fixing agent and the size of bubbles generated by the normal reaction of the color fixing agent are both bubble generation data under the standard stirring state;

[0154] The bubble factor is generated by taking the weighted sum of the bubble quantity evaluation value and the bubble size evaluation value.

[0155] The pressure factor is obtained as follows:

[0156] The pressure value in the reactor 1 is obtained, and the pressure value is subjected to difference processing with the pressure threshold to generate a pressure difference; the pressure threshold refers to the maximum value of the standard pressure range in the reactor 1 during the production process of the fixing agent;

[0157] It should be explained that the standard pressure range refers to the pressure range that should be maintained in the reactor 1 during the standard production process of the color fixing agent;

[0158] The pressure difference is ratioed to the pressure threshold to generate a pressure factor.

[0159] As a preferred embodiment of the present invention, the friction factor is obtained as follows:

[0160] Based on the frictional heat generation formula, through the formula J = V 2 *μ*A, generates friction heat J;

[0161] In the formula, A represents the contact area between the stirring blade 302 and the color fixing agent mixed raw material, μ represents the friction coefficient of the stirring blade 302, and V represents the stirring speed of the stirring blade 302;

[0162] It should be explained that the friction coefficient μ of the stirring blade 302 is determined according to the viscosity of the color fixing agent mixed raw material and the type of the stirring blade 302;

[0163] A friction heat threshold is preset, and the friction heat J is subjected to difference processing with the friction heat threshold to generate a friction heat difference; the friction heat threshold refers to the maximum value at which the heat generated by friction will not affect the temperature of the color fixing agent mixed raw material;
