Technical Field
[0001] The invention belongs to the technical field of integrated heating and cooling thermostats, and relates to an integrated heating and cooling thermostat based on an electromagnetic heating coil. Background Art
[0002] In the production process of rubber and plastic industry, it is often necessary to heat the raw materials to meet the process requirements such as plasticization, melting or molding. For example, special equipment such as extruders and calenders need to be equipped with thermostats to make the system temperature meet the process requirements to produce qualified products. The first core component of the thermostat is the heating chamber, which has a high-power electric heating tube. After power is turned on, the electric heating tube heats up to raise the temperature of the system medium. The second core component of the thermostat is the cooling heat exchanger. The thermostat controls the action of the heating chamber and the cooling heat exchanger through the electronic control system to achieve the purpose of constant temperature of the system circulating medium.
[0003] Traditional thermostats mainly use electric heating tubes as heating elements, which have the disadvantages of short life, long maintenance time, low thermal efficiency, and high power consumption. In addition, the system also needs to be equipped with a heat exchanger independently, resulting in a large volume of the whole machine, crowded internal structure, cumbersome pipe connections, and difficult maintenance. As a result, traditional thermostats cannot improve heating and cooling efficiency, save energy costs, and improve resource utilization.
[0004] Traditional thermostats also lack the ability to detect and analyze the entire temperature control process, which is not conducive to improving product processing quality and production efficiency, nor is it conducive to optimizing and adjusting the thermostat. It is impossible to improve the response speed and stability of the thermostat, and it is impossible to reduce the impact of temperature fluctuations on the production process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] See also Figure 1 As shown, the present invention provides an integrated heating and cooling thermostat based on electromagnetic heating coils, and the specific modules are distributed as follows: preheating stage detection and analysis module, production operation stage detection module, production operation stage analysis module, shutdown cooling stage detection and analysis module, effect detection and analysis module and database.

[0023] The preheating phase detection and analysis module is used to record the device where the target integrated heating and cooling thermostat is deployed as the target device, extract the preheating information of the target device from the database, obtain the current preheating temperature value in real time, and analyze the heating operation parameters of the target integrated heating and cooling thermostat.
[0024] It needs to be further explained that the schematic diagram of the system implementation process is as follows Figure 2 shown.
[0025] In a specific example, the target equipment includes but is not limited to an extruder and a calender.
[0026] As a preferred feasible example, the preheating information of the target device includes a thermal conductivity and a thermal conductivity volume of the target device.
[0027] The heating operation parameters include heating power and electromagnetic heating frequency.
[0028] It needs to be further explained that the specific method of obtaining the heating power and the electromagnetic heating frequency is: directly measuring the heating power and the electromagnetic heating frequency using the power meter and frequency meter arranged in the target integrated heating and cooling thermostat.
[0029] As a preferred feasibility example, the specific analysis method of the heating operation parameters of the target integrated heating and cooling thermostat is: the maximum heating power of the target integrated heating and cooling thermostat is used as the initial heating power of the target integrated heating and cooling thermostat in the preheating stage, and then the heating power P of the target integrated heating and cooling thermostat in the preheating stage is obtained in real time according to the analysis formula P=(T1-T1′)*k*V, and it is recorded as the heating power of the target integrated heating and cooling thermostat, wherein T1 and T1′ are the target preheating temperature value and the current preheating temperature value, respectively, and k and V are the thermal conductivity and thermal conductivity volume of the target device, respectively;
[0030] The heating power of the target integrated heating and cooling thermostat is further matched with the electromagnetic heating frequencies corresponding to the heating powers stored in the database to obtain the electromagnetic heating frequency of the target integrated heating and cooling thermostat.
[0031] It needs to be further explained that the heating power and electromagnetic heating frequency of the target integrated heating and cooling thermostat are obtained in real time, that is, the heating operation parameters of the target integrated heating and cooling thermostat are obtained in real time according to actual conditions.
[0032] The present invention obtains the preheating information and current preheating temperature value of the target device and analyzes the heating operating parameters of the target integrated heating and cooling thermostat, which helps to monitor the preheating status of the target device in real time, thereby adjusting the heating operating parameters in time, which is conducive to more precise temperature control and meeting the temperature control requirements in the production process.
[0033] The shutdown cooling stage detection and analysis module is used to obtain the temperature value of the target device in the shutdown cooling stage in real time, and analyze the cooling operation parameters of the target integrated heating and cooling thermostat based on the temperature value.
[0034] As a preferred feasibility example, the cooling operation parameters include valve opening, flow rate and temperature of the cooling medium.
[0035] It needs to be further explained that the specific method of obtaining the valve opening, flow rate and temperature of the cooling medium is: using the valve position sensor, flow meter and temperature sensor arranged in the target integrated heating and cooling thermostat to directly measure the valve opening, flow rate and temperature of the cooling medium.
[0036] As a preferred feasibility example, the specific analysis method of the cooling operation parameters of the target integrated heating and cooling thermostat is: the maximum valve opening, maximum flow rate and minimum temperature of the cooling medium of the target integrated heating and cooling thermostat are used as the initial valve opening, initial flow rate and initial temperature of the target integrated heating and cooling thermostat in the shutdown cooling stage, and then according to the analysis formula Obtain in real time the temperature drop ratio of the target integrated heating and cooling thermostat during the shutdown cooling stage, where T5 and T5′ are the temperature value of the target device during the shutdown cooling stage and the target cooling temperature value extracted from the database, respectively;
[0037] The temperature drop ratio of the target integrated heating and cooling thermostat during the shutdown cooling stage is compared with the valve opening, flow rate and temperature of the cooling medium corresponding to each temperature drop ratio stored in the database, so as to obtain the valve opening, flow rate and temperature of the cooling medium of the target integrated heating and cooling thermostat during the shutdown cooling stage, and record them as the valve opening, flow rate and temperature of the cooling medium of the target integrated heating and cooling thermostat.
[0038] It needs to be further explained that the valve opening, flow rate and temperature of the cooling medium of the target integrated heating and cooling thermostat are obtained in real time, that is, the target integrated heating and cooling thermostat obtains the cooling operation parameters of the target integrated heating and cooling thermostat in real time according to actual conditions.
[0039] The present invention obtains the temperature value of the target device during the shutdown cooling stage and analyzes the cooling operation parameters of the target integrated heating and cooling thermostat, which helps to ensure that the device can be quickly and stably cooled to a safe temperature after shutdown, avoids equipment instability or safety hazards caused by temperature fluctuations or excessively high temperatures, and reduces unnecessary cooling time by adjusting the cooling operation parameters of the thermostat and utilizing optimized cooling strategies.
[0040] The production operation phase detection module is used to obtain the operating data information of the target device and its ambient temperature in real time, and obtain the current operating temperature value in real time.
[0041] As a preferred feasible example, the operation data information of the target device includes the device type and various operation parameter values of the device.
[0042] It needs to be further explained that the specific method of obtaining the device type and various operating parameter values of the target device is: directly extracting the device type of the target device from the instruction manual of the target device, and directly extracting various operating parameter values of the target device from the control panel of the target device.
[0043] The production operation phase analysis module is used to analyze the current operating temperature compensation value of the target integrated heating and cooling thermostat, and further analyze the working mode requirements and working mode parameters of the target integrated heating and cooling thermostat, where the working mode requirements include continuous heating mode, intermittent heating mode and constant temperature control mode, and the working mode parameters include heating operation parameters and cooling operation parameters.
[0044] It should be further explained that in the continuous heating mode, the electromagnetic heating coil of the heating system will continuously output heat at a relatively stable power, and the cooling system is in a standby state.
[0045] In the intermittent heating mode, the heating system will be turned on and off at a certain time interval or according to the state of the rubber and plastic materials in the equipment. During the intermittent period when the heating system stops heating, the cooling system will play a role.
[0046] In the constant temperature control mode, the heating system needs to have high-precision power regulation capability, and the cooling system is also regulated by constant temperature control.
[0047] As a preferred feasibility example, the specific analysis method of the current operating temperature compensation value of the target integrated heating and cooling thermostat is: extracting various operating parameter values of the target device and the ambient temperature of the target device, respectively recorded as Para i , T env, where i = 1, 2, ..., a, i is the number of each type of equipment operating parameters, a is the number of categories of equipment operating parameters, and the current operating temperature compensation value of the target integrated heating and cooling thermostat is analyzed Among them, Para i ′、T tar are the i-th reference operating parameter value of the target device and the current target operating temperature value, respectively; T0 is the temperature value corresponding to the reference operating parameter value of the target device.
[0048] It needs to be further explained that the essence of analyzing the current operating temperature compensation value of the target integrated heating and cooling thermostat is to determine what additional adjustments need to be made to the operating temperature based on the difference between the actual operating conditions of the current equipment and the reference operating conditions, so that the equipment temperature can better meet the expected control target.
[0049] As an external but significant factor, it is also necessary to analyze the ambient temperature separately. When the ambient temperature changes, the heat exchange between the equipment and the outside world changes, which directly affects the heat balance inside the equipment and thus affects the operating temperature.
[0050] As a preferred feasibility example, the specific analysis method of the working mode requirements and working mode parameters of the target integrated heating and cooling thermostat is: extracting the current operating standard temperature value T of the target integrated heating and cooling thermostat from the database sta , analyze the representative value of the working mode requirements of the target integrated heating and cooling thermostat Where T run is the current operating temperature value, T thr , T th ' r They are respectively the second approximate difference and the first approximate difference between the current operating temperature value extracted from the database and the current operating standard temperature value. When Y=1, it means that the working mode requirement of the target integrated heating and cooling thermostat is the continuous heating mode. When Y=2, it means that the working mode requirement of the target integrated heating and cooling thermostat is the intermittent heating mode. When Y=3, it means that the working mode requirement of the target integrated heating and cooling thermostat is the constant temperature control mode.
[0051] A specific example, (1) in continuous heating mode, This means that the current operating temperature is much lower than the current standard operating temperature. In order to make the temperature rise to the standard temperature as quickly as possible or meet the temperature requirements of the production process, the target integrated heating and cooling thermostat needs to work in continuous heating mode. For example, if the current operating temperature is 150°C and the current standard operating temperature is 180°C, T thrIt is 10℃, and since 180℃-150℃>10℃, it is determined that the thermostat needs to enter the continuous heating mode to continuously provide heat to the equipment and cause the temperature to rise.
[0052] (2) In intermittent heating mode, This indicates that there is a certain gap between the current operating temperature value and the current operating standard temperature value, but the gap is not very large. There is no need for continuous heating, and it is more appropriate to use intermittent heating mode. In intermittent heating mode, the heating system will be turned on and off periodically, which can not only add heat to gradually approach the standard temperature, but also prevent the temperature from rising too high and too fast and exceeding the reasonable range. For example, if the current operating temperature value is 172℃ and the standard temperature value is 180℃, T th ' r It is 5℃. Since 5℃<180℃-172℃<10℃, it is determined that the thermostat should work in intermittent heating mode.
[0053] (3) In constant temperature control mode, This means that the current operating temperature is very close to the standard temperature. The focus is to maintain the temperature stability and keep it as close to the standard temperature as possible. Therefore, the target integrated heating and cooling thermostat requires a constant temperature control mode. For example, if the current operating temperature is 178°C and the standard temperature is 180°C, since 180°C-178°C=2°C<5°C, the thermostat enters the constant temperature control mode, and the heating system and cooling system work together to make subtle adjustments to the temperature to maintain a constant temperature.
[0054] Furthermore, the working mode parameters of the target integrated heating and cooling thermostat can be obtained in the same way as the analysis method of the heating operation parameters and the cooling operation parameters of the target integrated heating and cooling thermostat.
[0055] The present invention obtains the operating data information of the target device, its ambient temperature and the current operating temperature value, analyzes the current operating temperature compensation value of the target integrated heating and cooling thermostat and the operating mode requirements and operating mode parameters of the target integrated heating and cooling thermostat, and makes fine adjustments based on the temperature information, which is beneficial to ensuring that the target device operates stably within the set temperature range, selecting the appropriate operating mode according to actual needs, more effectively controlling the temperature, reducing unnecessary energy consumption, and improving resource utilization efficiency.
[0056] The effect detection and analysis module is used to obtain the operation data information of the whole process of the target integrated heating and cooling thermostat and analyze the working evaluation index of the target integrated heating and cooling thermostat.
[0057] As a preferred feasibility example, the operation data information of the entire process of the target integrated heating and cooling thermostat includes operation data information corresponding to the preheating stage, operation data information corresponding to the production operation stage, and operation data information corresponding to the shutdown cooling stage.
[0058] Among them, the operating data information corresponding to the preheating stage includes the voltage and current of the electromagnetic heating coil during each heating, as well as the duration of the preheating stage, the preheating heating efficiency and the preheating temperature rise rate.
[0059] It is necessary to further explain that (1) preheating efficiency is an important evaluation index, which reflects how much of the input energy is actually used to heat the rubber and plastic materials, and can be measured by the ratio of actual absorbed heat to input heat. Higher preheating efficiency means more reasonable energy utilization in the preheating stage, less energy wasted, and better energy saving of the equipment.
[0060] (2) The preheating temperature rise rate reflects the speed of temperature rise during the preheating process. A reasonable temperature rise rate is critical to ensure that the rubber and plastic materials are heated evenly and achieve the expected preheating effect. If the temperature rise rate is too fast, it may cause a large temperature difference between the inside and outside of the material, resulting in thermal stress and other problems; while a rate that is too slow will extend the preheating time and affect production efficiency. The temperature rise control of the thermostat during the preheating stage can be evaluated by comparing the changes in the temperature rise rate during different heating processes, analyzing its stability and whether it meets the preset heating curve requirements.
[0061] (3) The duration of the preheating phase is a key evaluation dimension. A shorter preheating time can improve overall production efficiency while meeting temperature and heating quality requirements. Compare the actual preheating phase duration with the equipment design requirements or the average preheating time of the same type of equipment. If it is significantly longer, it may indicate insufficient heating power, excessive heat loss, or other problems that affect the preheating speed, which require further investigation and optimization.
[0062] It needs to be further explained that the specific method of obtaining the voltage and current of the electromagnetic heating coil during each heating in the preheating stage of the target integrated heating and cooling thermostat, as well as the preheating stage duration, preheating heating efficiency and preheating temperature rise rate is: using the power analyzer arranged in the target integrated heating and cooling thermostat to directly measure the voltage and current of the electromagnetic heating coil during each heating in the preheating stage of the target integrated heating and cooling thermostat.
[0063] The timer arranged in the target integrated heating and cooling thermostat is used to record the time from starting preheating to the target preheating temperature value, and the time is recorded as the preheating phase time of the preheating phase of the target integrated heating and cooling thermostat.
[0064] According to the calculation formula The preheating heating efficiency η of the target integrated heating and cooling thermostat in the preheating stage is obtained, where m and c are the mass and specific heat capacity of the target device, respectively, P is the heating power in the preheating stage detected by the power analyzer arranged in the target integrated heating and cooling thermostat, t is the preheating stage duration of the target integrated heating and cooling thermostat in the preheating stage, T1 and T2 are the target preheating temperature value and the temperature value when the target integrated heating and cooling thermostat starts preheating, respectively.
[0065] It should be noted that the specific method for obtaining the mass and specific heat capacity of the target device is: matching the device type of the target device with the corresponding mass and specific heat capacity of each device type stored in the database to obtain the mass and specific heat capacity of the target device.
[0066] According to the calculation formula Get the preheating temperature rise rate TV of the target integrated heating and cooling thermostat in the preheating phase rise .
[0067] The operation data information corresponding to the production operation stage includes the response time of each heating demand, the response time of each cooling demand and the temperature deviation value of each detection.
[0068] It is important to further explain that (1) the response time for each heating demand and the response time for each cooling demand are important indicators for measuring whether the thermostat can quickly adapt to the temperature adjustment requirements during the production process. A shorter response time means that when the production process requires heating or cooling, the thermostat can quickly start the heating or cooling function, so that the temperature in the equipment is adjusted to the appropriate range in time, ensuring the continuity of production and the stability of product quality.
[0069] (2) The temperature deviation value of each test directly reflects the accuracy of the temperature control of the thermostat. Ideally, the temperature deviation value should be as small as possible, close to zero.
[0070] It needs to be further explained that the specific method of obtaining the response time of each heating demand, the response time of each cooling demand and the temperature deviation value of each detection during the production and operation stage of the target integrated heating and cooling thermostat is: using the end time point and the start time point of each heating demand and each cooling demand of the target integrated heating and cooling thermostat during the production and operation stage, and then subtracting the end time point from the start time point to obtain the response time of each heating demand and the response time of each cooling demand during the production and operation stage of the target integrated heating and cooling thermostat.
[0071] The actual temperature value of each detection during the production and operation stage of the target integrated heating and cooling thermostat is subtracted from the target temperature value to obtain the temperature deviation value of each detection during the production and operation stage of the target integrated heating and cooling thermostat.
[0072] It should be noted that the actual temperature value is directly measured by a temperature sensor arranged in the target integrated heating and cooling thermostat, and the target temperature value is the temperature value required by the target device when making rubber and plastic products stored in the database.
[0073] The operation data information corresponding to the shutdown cooling stage includes cooling efficiency, cooling time and cooling temperature drop rate.
[0074] It is necessary to further explain that (1) cooling efficiency reflects the effectiveness of the cooling system in removing excess heat from the equipment. A high cooling efficiency means that the cooling system has good performance and can quickly and effectively reduce the temperature of the equipment, avoiding potential safety hazards caused by the equipment being in a high temperature state for a long time and adverse effects on the performance of the equipment itself and rubber and plastic materials, such as preventing deformation and accelerated aging of rubber and plastic materials due to slow cooling.
[0075] (2) The cooling temperature drop rate reflects the speed of temperature reduction during the cooling process. A reasonable cooling rate helps the equipment to cool evenly and prevents damage to equipment components or material structures caused by thermal stress caused by too fast cooling. At the same time, it should not be too slow to affect the subsequent operation arrangements after shutdown. By analyzing whether the cooling temperature drop rate is within a reasonable range and its stability, the rationality of temperature control in the cooling stage can be evaluated.
[0076] (3) Cooling time is also an important consideration. A shorter cooling time can shorten equipment downtime and improve overall equipment utilization while meeting safety and equipment material performance requirements.
[0077] It should be further explained that the specific method for obtaining the cooling efficiency, cooling time and cooling temperature drop rate of the target integrated heating and cooling thermostat during the shutdown cooling stage is as follows: according to the calculation formula The cooling efficiency η1 of the target integrated heating and cooling thermostat in the shutdown cooling stage is obtained, where T3 and T4 are the temperature values of the target integrated heating and cooling thermostat when the shutdown cooling is started and when the shutdown cooling is ended, respectively, and E is the electric energy consumed by the target integrated heating and cooling thermostat in the shutdown cooling stage.
[0078] It should be noted that the temperature values when starting the shutdown cooling and when ending the shutdown cooling are directly measured by the temperature sensor arranged in the target integrated heating and cooling thermostat. The electric energy consumed in the shutdown cooling stage is obtained by subtracting the meter reading when ending the shutdown cooling and the meter reading when starting the shutdown cooling in the arranged electric meter.
[0079] The timer arranged in the target integrated heating and cooling thermostat is used to record the duration from starting the shutdown cooling to ending the shutdown cooling, which is recorded as the cooling duration t′ of the shutdown cooling stage of the target integrated heating and cooling thermostat.
[0080] According to the calculation formula Get the cooling temperature drop rate TV of the target integrated heating and cooling thermostat during the shutdown cooling phase down .
[0081] As a preferred feasibility example, the specific analysis method of the working evaluation index of the target integrated heating and cooling thermostat is as follows: extract the voltage and current of the electromagnetic heating coil during each heating in the preheating stage of the whole process of the target integrated heating and cooling thermostat, as well as the preheating stage duration, preheating heating efficiency and preheating temperature rise rate, which are recorded as Vol j , Ele j ,t,η,TV rise , where j = 1, 2, ..., b, j is the number of each heating, b is the number of heatings, and the corresponding work evaluation index IndexP of the preheating stage of the target integrated heating and cooling thermostat is analyzed.
[0082] As a preferred feasibility example, the specific analysis method of the work evaluation index corresponding to the preheating stage of the target integrated heating and cooling thermostat is: according to the analysis formula The corresponding working evaluation index IndexP of the preheating stage of the target integrated heating and cooling thermostat is obtained, where σ1 and σ2 are the fluctuation indexes of the voltage and current of the electromagnetic heating coil during the heating in the preheating stage, respectively. Vol0 is the set allowable voltage deviation, Ele0 is the set allowable current deviation, t0, η0, TV r ' ise They are the preheating stage duration threshold, preheating heating efficiency threshold and standard preheating temperature rise rate respectively. μ1 is the minimum value set to prevent the denominator from being 0, and its unit is hour.
[0083] Extract the heating demand response time, cooling demand response time and temperature deviation value of each detection during the production operation stage of the target integrated heating and cooling thermostat, and record them as ΔT h , q=1,2,...,Q, q is the number of each heating demand, Q is the number of heating demands, g=1,2,...,G, g is the number of each cooling demand, G is the number of cooling demands, h=1,2,...,H, h is the number of each detection, H is the number of detections, and the corresponding work evaluation index IndexO of the production operation stage of the target integrated heating and cooling thermostat is analyzed.
[0084] As a preferred feasibility example, the specific analysis method of the corresponding work evaluation index of the production operation stage of the target integrated heating and cooling thermostat is: according to the analysis formula The corresponding work evaluation index IndexO of the production operation stage of the target integrated heating and cooling thermostat is obtained, where ΔT0 is the set heating demand response time threshold, cooling demand response time threshold and allowable temperature deviation value, μ2, μ3, and μ4 are the set minimum values to prevent the denominator from being 0, and their units are hours, hours, and degrees Celsius, respectively.
[0085] Extract the cooling efficiency, cooling time and cooling temperature drop rate of the target integrated heating and cooling thermostat during the shutdown cooling phase, which are recorded as η1, t′, TV down , analyze the corresponding work evaluation index IndexS of the shutdown cooling stage of the target integrated heating and cooling thermostat.
[0086] As a preferred feasibility example, the specific analysis method of the corresponding work evaluation index of the shutdown cooling stage of the target integrated heating and cooling thermostat is: according to the analysis method The corresponding work evaluation index IndexS of the shutdown cooling stage of the target integrated heating and cooling thermostat is obtained, where η1′, t′0, TV d ' own are the cooling efficiency threshold, cooling time threshold and cooling temperature drop rate threshold set in the shutdown cooling stage respectively, and μ5 is the minimum value set to prevent the denominator from being 0, and its unit is hour.
[0087] According to the analytical formula Index=IndexP+IndexO+IndexS, the working evaluation index Index of the target integrated heating and cooling thermostat is obtained.
[0088] The working evaluation index of the target integrated heating and cooling thermostat is compared with the set working evaluation index threshold. If the working evaluation index of the target integrated heating and cooling thermostat is greater than the working evaluation index threshold, the working evaluation of the target integrated heating and cooling thermostat is recorded as qualified; otherwise, the working evaluation of the target integrated heating and cooling thermostat is recorded as unqualified, and feedback is given.
[0089] The database is used to store preheating information of the target device, store the electromagnetic heating frequency corresponding to each heating power, store the standard temperature values of each stage of operation of the target integrated heating and cooling thermostat, store the second approximate difference and the first approximate difference between the current operating temperature value and the current operating standard temperature value, store the target cooling temperature value, and store the valve opening, flow rate and temperature of the cooling medium corresponding to each temperature drop ratio.
