Description

Technical Field

[0001] The present application relates to the technical field of production temperature monitoring, and more specifically, to a production temperature monitoring method and system for chemical rubber accelerators. Background Art

[0002] Rubber accelerators are a type of chemical used to accelerate the vulcanization reaction of rubber. They can promote the cross-linking between rubber molecules and improve the mechanical strength, wear resistance and aging resistance of rubber products. Common rubber accelerators include sulfurized phenol compounds and peroxide accelerators. They are widely used in the rubber industry according to different vulcanization mechanisms and application requirements, such as in the production process of tires, rubber tubes and other products.

[0003] In the production process of rubber accelerators, temperature control in chemical reactors is crucial, and is usually controlled by advanced temperature monitoring and control systems. In the production process, the reaction temperature is controlled by monitoring the temperature of the rubber accelerator inside the chemical reactor and adjusting the flow of the heating or cooling medium. This ensures that the reaction can be carried out under ideal temperature conditions and the cross-linking and bonding of the rubber accelerator molecules can reach the optimal state. However, the supply of heating and cooling media will be unstable during the production temperature control process, and the temperature distribution of the rubber accelerator in the chemical reactor will be uneven. These will lead to insufficient reaction of the rubber accelerator in the chemical reactor, so that the purity of the finished rubber accelerator does not meet the established standards. Therefore, how to control the valve opening of the heating medium and cooling medium in the chemical reactor through the temperature characteristics of the rubber accelerator during production to achieve pre-adjustment of the production temperature of the rubber accelerator is a difficult problem faced by the industry.

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] The embodiment of the present application provides a production temperature monitoring method and system for chemical rubber accelerators, the core of which is to collect temperature data of the fluid state of the rubber accelerator in the chemical reactor during production, and then obtain the fluid temperature data of the rubber accelerator; perform redundant elimination of the fluid temperature data of the rubber accelerator according to the data collection time point to obtain the redundant elimination data of the fluid temperature of the rubber accelerator, and determine the temperature turbulence coefficient of the rubber accelerator in the chemical reactor through the redundant elimination data of the fluid temperature; monitor the valve opening of the temperature control valve in the chemical reactor during production, determine the temperature trend characteristics of the rubber accelerator according to the valve opening and the heating state of the rubber accelerator at the current moment, and determine the production temperature monitoring characteristics of the rubber accelerator in the chemical reactor based on the temperature trend characteristics, the temperature turbulence coefficient and the fluid temperature data; send the adjustment signal of the production temperature of the rubber accelerator to the industrial monitoring and dispatching center according to the production temperature monitoring characteristics and the reaction temperature range of the rubber accelerator. The above scheme can be used to control the valve opening of the heating medium and the cooling medium in the chemical reactor based on the temperature characteristics of the rubber accelerator to achieve pre-adjustment of the production temperature of the rubber accelerator.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 , which is an exemplary flow chart of a method for monitoring the production temperature of a chemical rubber accelerator according to some embodiments of the present application. The method 100 for monitoring the production temperature of a chemical rubber accelerator mainly includes the following steps:

[0047] In step 101, temperature data of the fluid state of the rubber accelerator in the chemical reaction kettle during production is collected to obtain fluid temperature data of the rubber accelerator.

[0048] In some embodiments, the temperature data of the fluid state of the rubber accelerator in the chemical reactor during production is collected by a thermistor sensor; it should be noted that the rubber accelerator described in the present application is a sulfurized phenol compound, which is usually in a fluid (liquid) state when reacting in a chemical reactor; in specific implementation, first, the thermistor sensor is installed inside the chemical reactor to ensure that it can accurately measure the temperature of the rubber accelerator; then, the thermistor sensor is connected to a temperature data acquisition system, which can be achieved by connecting the wire of the thermistor sensor to a temperature data acquisition device or a control device such as a PLC (programmable logic controller); finally, the temperature data acquisition system is started to start recording the temperature data of the fluid state of the rubber accelerator, thereby obtaining the fluid temperature data of the rubber accelerator, that is, the fluid temperature data represents the temperature data of the rubber accelerator in the fluid state.

[0049] In step 102, the fluid temperature data of the rubber accelerator is redundantly eliminated according to the data collection time point to obtain the redundant temperature data of the rubber accelerator, and the temperature turbulence coefficient of the rubber accelerator in the chemical reactor is determined by the redundant temperature data of the fluid.

[0050] Preferably, in some embodiments, reference Figure 2 As shown in FIG. 1 , this figure is an exemplary flow chart for determining redundant data of fluid temperature in some embodiments of the present application. In this embodiment, redundant data of the fluid temperature of the rubber accelerator is obtained according to the data acquisition time point, and the following steps can be used to obtain the redundant data of the fluid temperature of the rubber accelerator:

[0051] First, in step 1021, for each data collection time point, the fluid temperature value of the rubber accelerator corresponding to the data collection time point in the fluid temperature data is obtained;

[0052] Then, in step 1022, the fluid temperature redundant value corresponding to the data collection time point is determined according to the fluid temperature value of the rubber accelerator corresponding to the data collection time point and the preset temperature redundant adjustment item, so as to obtain the fluid temperature redundant value corresponding to each data collection time point;

[0053] Finally, in step 1023, the fluid temperature redundant data of the rubber accelerator is determined from the fluid temperature redundant values ​​corresponding to all data collection time points.

[0054] It should be noted that, in the present application, the fluid temperature redundant data is data composed of fluid temperature redundant values ​​in chronological order, and the fluid temperature redundant values ​​represent the fluid temperature values ​​after the redundant operation to remove the interference noise; in specific implementation, first, the acquisition time point when the thermistor sensor is monitoring, that is, the data acquisition time point, can be obtained, and for each data acquisition time point, the fluid temperature value of the rubber accelerator corresponding to the data acquisition time point is obtained in the fluid temperature data; then, a temperature redundant adjustment item can be preset according to the historical experimental data, and the temperature redundant adjustment item is used to control the redundant accuracy, so as to obtain the fluid temperature value of the rubber accelerator corresponding to the data acquisition time point before the data acquisition time point, and then the data can be obtained. The redundant value of the fluid temperature corresponding to the collection time point, for example, the redundant value of the fluid temperature corresponding to the nth data collection time point = the redundant adjustment item of the temperature * the fluid temperature value of the rubber accelerator corresponding to the nth data collection time point + (1-the redundant adjustment item of the temperature) * the fluid temperature value of the rubber accelerator corresponding to the n-1th data collection time point, wherein when the value of n is 1, the fluid temperature value of the rubber accelerator corresponding to the n-1 data collection time point is set to a default value, which can be preset by experience. The redundant value of the fluid temperature corresponding to each data collection time point can be obtained by the above method; finally, the redundant value of the fluid temperature corresponding to all the data collection time points can be used to form the redundant data of the fluid temperature of the rubber accelerator in chronological order.

[0055] Preferably, in some embodiments, the temperature turbulence coefficient of the rubber accelerator in the chemical reactor can be determined by the fluid temperature redundant data in the following manner, namely:

[0056] Performing data clustering on the redundant data of fluid temperature to obtain a plurality of redundant data clusters of fluid temperature;

[0057] Determine the temperature turbulence value of each fluid temperature redundant data cluster;

[0058] The temperature turbulence coefficient of the rubber accelerator in the chemical reactor is determined based on the temperature turbulence values ​​of all fluid temperature redundant data clusters.

[0059] It should be noted that, in the present application, the temperature turbulence coefficient is an indicator used to represent the degree of temperature fluctuation of the rubber accelerator in the fluid state in the chemical reactor, and the temperature turbulence value represents the degree of fluctuation of the overall temperature value of the fluid temperature redundant data cluster; in specific implementation, first, the fluid temperature redundant data can be clustered by the K-means clustering algorithm to obtain multiple fluid temperature redundant data clusters; then, for each fluid temperature redundant data cluster, the ratio of the total number of data in the fluid temperature redundant data cluster to the total number of data of the fluid temperature redundant data cluster of the rubber accelerator can be used as the temperature turbulence value of the fluid temperature redundant data cluster, thereby obtaining the temperature turbulence value of each fluid temperature redundant data cluster; finally, for each fluid temperature redundant data cluster, the product of the temperature turbulence value of the fluid temperature redundant data cluster and its logarithm is calculated, and the sum of all calculation results is dimensionally eliminated, and the final result after dimension elimination is used as the temperature turbulence coefficient of the rubber accelerator in the chemical reactor.

[0060] In addition, it should be noted that noise and outliers in the fluid temperature data can be removed through redundancy elimination, which is convenient for improving the accuracy and reliability of the fluid temperature data, thereby obtaining fluid temperature redundant data, and determining the temperature turbulence coefficient based on the fluid temperature redundant data. The temperature turbulence coefficient can better measure the temperature fluctuation characteristics of the rubber accelerator in the chemical reactor.

[0061] In step 103, the valve opening of the temperature control valve in the chemical reactor during production is monitored, and the temperature trend characteristics of the rubber accelerator are determined based on the valve opening and the heating state of the rubber accelerator at the current moment. The production temperature monitoring characteristics of the rubber accelerator in the chemical reactor are determined based on the temperature trend characteristics, the temperature turbulence coefficient and the fluid temperature data.

[0062] In some embodiments, the valve opening of the temperature control valve in the chemical reactor during production is monitored by an angle sensor; in specific implementation, first, the angle sensor is installed on the rotating part of the temperature control valve in the chemical reactor to monitor the valve opening angle in real time; then, the data acquisition system is started to collect the angle data of the valve opening of the temperature control valve, that is, the valve opening of the temperature control valve in the chemical reactor during production, and the valve opening represents the opening angle of the temperature control valve; it should be noted that when the valve opening of the temperature control valve increases, it indicates that the supply of the heating medium will increase, and the fluid temperature of the rubber accelerator in the chemical reactor will rise; conversely, when the valve opening of the temperature control valve decreases, it indicates that the supply of the heating medium will decrease, and the fluid temperature of the rubber accelerator in the chemical reactor will decrease.

[0063] Preferably, in some embodiments, reference Figure 3As shown in FIG. 1 , this figure is an exemplary flow chart for determining temperature trend characteristics in some embodiments of the present application. In this embodiment, the temperature trend characteristics of the rubber accelerator are determined according to the valve opening and the heating state of the rubber accelerator at the current moment, which can be achieved by the following steps:

[0064] First, in step 1031, the flow rate of the heating medium supplied to the chemical reaction kettle is determined according to the valve opening;

[0065] Then, in step 1032, the temperature change trend of the rubber accelerator is simulated based on the heating state of the rubber accelerator at the current moment to obtain the fluid temperature trend of the rubber accelerator in the chemical reactor;

[0066] Finally, in step 1033, the temperature trend characteristics of the rubber accelerator are determined by the flow rate of the heating medium and the fluid temperature trend quantity of the rubber accelerator in the chemical reactor.

[0067] It should be noted that, in the present application, the temperature trend characteristic of the rubber accelerator is a characteristic used to describe the temperature change trend of the fluid of the rubber accelerator, and the fluid temperature trend quantity represents the temperature change quantity of the fluid of the rubber accelerator in the chemical reactor. In specific implementation, first, the cross-sectional area of ​​the temperature control valve opening can be calculated according to the valve opening, and the flow rate of the heating medium can be obtained, so that the heating medium flow rate in the chemical reactor can be calculated, wherein the heating medium flow rate = the cross-sectional area of ​​the temperature control valve opening * the flow rate of the heating medium; then, the heating state of the rubber accelerator at the current moment can be input into the simulation software to simulate the temperature change trend of the rubber accelerator, so as to obtain the fluid temperature trend quantity of the rubber accelerator in the chemical reactor, and the heating state refers to whether the rubber accelerator is being heated in the chemical reactor, as well as the intensity and duration of the heating, and different heating states will affect the change trend of the fluid temperature of the rubber accelerator; finally, the fluid temperature rise of the rubber accelerator in the chemical reactor can be calculated according to the heating medium flow rate, so that the sum of the fluid temperature rise and the fluid temperature trend quantity of the rubber accelerator can be taken as the value of the temperature trend characteristic of the rubber accelerator.

[0068] In some embodiments, the production temperature monitoring characteristics of the rubber accelerator in the chemical reactor can be determined based on the temperature trend characteristics, the temperature turbulence coefficient and the fluid temperature data in the following manner, namely:

[0069] Get a pre-trained production temperature prediction model;

[0070] The temperature trend characteristics and the fluid temperature data are used as input data, and the temperature turbulence coefficient is used as a prediction weight to input into the production temperature prediction model for prediction, thereby obtaining a prediction result;

[0071] The prediction results are used as production temperature monitoring features of rubber accelerators in chemical reactors.

[0072] In the specific implementation, first, in this application, a production temperature prediction model is constructed and trained based on machine learning technology, and a production temperature prediction model can also be constructed and trained based on methods such as statistical regression analysis, which is not limited here; then, the temperature trend characteristics and fluid temperature data are used as input data, and the temperature turbulence coefficient is used as the prediction weight to input into the production temperature prediction model for prediction. The production temperature prediction model will calculate according to the input data and the prediction weight to obtain the prediction result; finally, the prediction result can be used as the production temperature monitoring feature of the rubber accelerator in the chemical reactor, and the production temperature monitoring feature indicates the fluid temperature value that the rubber accelerator in the chemical reactor may reach during production.

[0073] It should be noted that by collecting the valve opening of the temperature control valve and the heating status of the rubber accelerator, the temperature trend characteristics of the rubber accelerator can be inferred in real time. Therefore, based on the temperature trend characteristics, temperature turbulence coefficient and fluid temperature data, the production temperature monitoring characteristics of the rubber accelerator can be predicted in time, which is convenient for timely adjustment of the production temperature in the production process.

[0074] In step 104, a signal for adjusting the production temperature of the rubber accelerator is sent to an industrial monitoring and dispatching center according to the production temperature monitoring characteristics and the reaction temperature range of the rubber accelerator.

[0075] In some embodiments, the following method can be used to send a rubber accelerator production temperature adjustment signal to the industrial monitoring and dispatching center according to the production temperature monitoring characteristics and the rubber accelerator reaction temperature range, namely:

[0076] When the production temperature monitoring characteristic is not in the rubber accelerator reaction temperature interval, if the production temperature monitoring characteristic is higher than the interval upper limit of the rubber accelerator reaction temperature interval, a production temperature reduction signal is sent to the industrial monitoring and dispatching center;

[0077] If the production temperature monitoring characteristic is lower than the lower limit of the rubber accelerator reaction temperature range, a production temperature increase signal is sent to the industrial monitoring and dispatching center;

[0078] When the production temperature monitoring characteristic is in the rubber accelerator reaction temperature range, a production temperature stable signal is sent to the industrial monitoring and dispatching center.

[0079] It should be noted that, in the present application, the rubber accelerator reaction temperature range refers to the production temperature range required for preparing a rubber accelerator that meets the established standards, and the rubber accelerator reaction temperature range can be obtained through literature data; in specific implementation, first, it is determined whether the production temperature monitoring characteristics are in the rubber accelerator reaction temperature range, and based on the judgment result, a rubber accelerator production temperature adjustment signal is sent to the industrial monitoring and dispatching center to achieve pre-adjustment of the production temperature of the rubber accelerator in the chemical reactor.

[0080] In the above embodiment, a signal for adjusting the production temperature of the rubber accelerator is sent to the industrial monitoring and dispatching center according to the judgment result; in specific implementation, when the production temperature monitoring characteristic is not in the reaction temperature interval of the rubber accelerator, if the production temperature monitoring characteristic is higher than the upper limit of the reaction temperature interval of the rubber accelerator, it means that the production temperature monitoring characteristic is too high, which will cause the rubber accelerator to overheat or react uncontrollably at this temperature. In this case, a production temperature reduction signal should be sent to the industrial monitoring and dispatching center to open the valve of the cooling medium in the chemical reactor, increase the supply of the cooling medium, and reduce the fluid temperature of the rubber accelerator in the reactor; if the production temperature monitoring characteristic is lower than the upper limit of the reaction temperature interval of the rubber accelerator, The lower limit of the rubber accelerator reaction temperature range indicates that the production temperature monitoring characteristic is too low, which will affect the reaction rate or cause incomplete reaction. In this case, a production temperature increase signal is sent to the industrial monitoring and dispatching center, thereby increasing the valve opening of the temperature control valve in the chemical reactor and increasing the supply of heating medium to increase the fluid temperature of the rubber accelerator in the reactor. When the production temperature monitoring characteristic is in the rubber accelerator reaction temperature range, it means that the current production temperature monitoring characteristic is in a suitable range and the rubber accelerator reaction conditions are good. In this case, a production temperature stabilization signal is sent to the industrial monitoring and dispatching center, and the valve opening of the current temperature control valve is kept unchanged to maintain the existing heating state.

[0081] It can be seen that in the present application, the valve opening of the heating medium and the cooling medium in the chemical reactor can be controlled based on the temperature characteristics of the rubber accelerator to achieve pre-adjustment of the production temperature of the rubber accelerator; wherein, firstly, the noise and abnormal values ​​in the fluid temperature data can be removed by redundancy, so as to improve the accuracy and reliability of the fluid temperature data, thereby obtaining the fluid temperature redundancy data, and determining the temperature turbulence coefficient based on the fluid temperature redundancy data, and the temperature turbulence coefficient can better measure the temperature fluctuation characteristics of the rubber accelerator in the chemical reactor; then, by collecting the valve opening of the temperature control valve and the heating state of the rubber accelerator, the temperature trend characteristics of the rubber accelerator can be inferred in real time, so based on the temperature trend characteristics, the temperature turbulence coefficient and the fluid temperature data, the production temperature monitoring characteristics of the rubber accelerator can be timely predicted, so as to adjust the production temperature in the production process in time; finally, the production temperature monitoring characteristics are compared with the reaction temperature range, and different production temperature adjustment signals are sent to the industrial monitoring and dispatching center according to the comparison results, so as to change the opening of the cooling medium valve and the temperature control valve in the chemical reactor according to the production temperature adjustment signal to control the production temperature of the rubber accelerator in the chemical reactor. In summary, the technical solution provided in the present application can control the valve opening of the heating medium and the cooling medium in the chemical reaction kettle based on the temperature characteristics of the rubber accelerator, so as to achieve pre-adjustment of the production temperature of the rubber accelerator.
