At the same time, the stirring structure is relatively simple, resulting in uneven mixing of the silicone sealant raw materials. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0027] Currently, the temperature of the silicone sealant production reactor is not easily controlled to the optimal level during use, which affects the reaction of the silicone sealant raw materials. At the same time, the stirring structure is relatively simple, resulting in uneven mixing of the silicone sealant raw materials.

[0028] In view of this, the present invention provides a temperature control and stirring optimization device for a silicone sealant production reactor. While stirring the silicone sealant raw material in the reactor, the device controls the discharge of medium through the heating pipe and the discharge of medium through the cooling pipe, so as to heat or cool the material in the reactor. The device can realize the connection between the temperature sensor detecting the material temperature and the external controller, and the controller can accurately control the valve operation, thereby effectively controlling the temperature of the material in the reactor to the optimal state, so that the silicone sealant raw material can react well.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a temperature control and stirring optimization device for an organosilicon sealant production reactor, including an outer shell 1 and a reactor 2. The reactor 2 is placed inside the outer shell 1. The reactor 2 and the outer shell 1 are connected by at least two connecting blocks 3. There is a sandwich between the outer shell 1 and the reactor 2 for filling with a medium. The connecting blocks 3 do not affect the transfer of the medium in the sandwich. The reactor 2 is model SMT-S212.

[0030] One end of the outer casing 1 is connected to a heating pipe 6, which is connected to an external heating medium pipe. A first electric valve 7 is installed on the heating pipe 6. The other end of the outer casing 1 is connected to a cooling pipe 8, which is connected to an external cooling medium pipe. A second electric valve 9 is installed on the cooling pipe 8. A vertical pipe 10 is connected to the bottom of the outer casing 1. The vertical pipe 10 is connected to the external heating medium pipe and the cooling medium pipe respectively through a three-way connector, so that the medium can be reheated or cooled, which is conducive to recycling. A third electric valve 11 is installed on the vertical pipe 10.

[0031] A temperature sensor 12 is installed at the bottom of the reactor 2, and at least three temperature sensors 12 are installed at equal intervals on the side wall. The temperature sensors 12 extend outside the outer shell 1, and a hole is opened at or near the center of the top of the reactor 2 to install the temperature sensor 12 so that it can be inserted into the material. The temperature sensor 12 includes a thermocouple and a resistance temperature probe (RTD).

[0032] Hardware connection

[0033] Temperature sensor 12 connection to controller: Based on the output signal type of temperature sensor 12 (e.g., analog or digital signal), select the appropriate interface module to connect the sensor to the controller. For example, analog temperature sensor 12 converts the analog signal to a digital signal via an analog-to-digital converter before connecting it to the controller's digital input port; digital temperature sensors can be directly connected via a corresponding digital interface (e.g., I / O). 2(e.g., C, SPI) are connected to the controller.

[0034] The controller is connected to the valves (first, second, and third electric valves): The controller typically controls the valves through devices such as relays, solid-state relays, or dedicated valve actuators. For electric valves, the control signal output by the controller (such as a PWM signal or a digital signal) is converted into a motor drive signal by the actuator, thereby controlling the valve opening. For pneumatic valves, an electrical converter is needed to convert the controller's electrical signal into a pneumatic signal, which is then used to drive the valve.

[0035] Software setup and programming

[0036] Temperature data acquisition and processing: The controller software needs to be programmed to read the data sent by the temperature sensor, process and convert it into the actual temperature value. Simultaneously, temperature alarm thresholds can be set to issue an alarm signal promptly when the temperature exceeds the normal range.

[0037] Control Algorithm Implementation: Based on the process requirements of the reactor, a suitable control algorithm, such as a PID control algorithm, is designed in the controller. The PID controller automatically adjusts the output of the control signal according to the difference between the set temperature and the actual measured temperature to achieve precise control of the valve opening and keep the material temperature inside the reactor near the set value.

[0038] Valve control logic: Write a program to control the valve based on temperature changes. For example, when the temperature is higher than the set value, the controller outputs a signal to open the valve, increasing the flow rate of the cooling medium or decreasing the flow rate of the heating medium; when the temperature is lower than the set value, the valve closes accordingly or decreases the flow rate of the cooling medium and increases the flow rate of the heating medium, thereby achieving closed-loop temperature control.

[0039] System debugging and optimization

[0040] Parameter tuning: After system installation, the controller parameters need to be debugged and optimized. For example, adjust the proportional, integral, and derivative parameters of the PID controller to obtain the best control effect, so that the temperature control has a fast response speed and a small overshoot.

[0041] Valve characteristic calibration: The valve's opening and flow characteristics are calibrated to ensure that the valve can accurately follow the controller's instructions, achieving precise temperature control. Simultaneously, the valve's actuation time, stroke, and other parameters are checked to ensure they meet system requirements.

[0042] System stability testing: Conduct long-term system operation tests to observe the stability and reliability of temperature control. Under different operating conditions (such as different production batches, changes in ambient temperature, etc.), verify whether the system can consistently maintain the material temperature within the specified range. If problems are found, further analyze the causes and optimize accordingly.

[0043] Through the above steps, the temperature sensor can detect the material temperature and connect to an external controller, and the controller can precisely control the valve operation, thereby achieving effective control of the material temperature inside the reactor.

[0044] A stirring rod 13 is installed on the drive structure of the reactor 2. An adjustment structure 14 is installed on the stirring rod 13. There are three adjustment structures 14. The adjustment structures 14 are equidistantly distributed on the stirring rod 13, and the two adjacent adjustment structures 14 are vertically distributed.

[0045] The adjustment structure 14 includes a mounting hole 15, a housing 16, a drive unit 17, and a stirring blade 18;

[0046] Mounting hole 15 is formed on stirring rod 13, housing 16 is installed in mounting hole 15, and sealing material is added between housing 16 and mounting hole 15 for sealing. Drive unit 17 is installed in housing 16, and stirring blade 18 is installed on drive parts on both sides of drive unit 17.

[0047] The drive unit 17 includes a U-shaped plate 20, a base 21, a servo motor 22, a double-threaded rod 23, a moving part 24, a connecting rod 25, a round hole 26, a rubber sleeve 27, and a limiting groove 28;

[0048] U-shaped plate 20 is installed inside housing 16, base 21 is installed on U-shaped plate 20, servo motor 22 is installed on base 21, and double-ended threaded rod 23 is rotatably mounted on U-shaped plate 20 on both sides via bearings. The output shaft of servo motor 22 is connected to double-ended threaded rod 23. Moving parts 24 are sleeved on both sides of double-ended threaded rod 23. Limit grooves 28 are opened on U-shaped plate 20, and moving parts 24 are respectively placed in limit grooves 28. Connecting rods 25 are respectively installed on moving parts 24. Circular holes 26 are opened on both sides of housing 16, and rubber sleeves 27 are installed in the circular holes 26. The rubber sleeves 27 are made of fluororubber. Connecting rods 25 pass through rubber sleeves 27, and the rubber sleeves 27 seal the gap between connecting rods 25 and circular holes 26 on housing 16. Stirring blades 18 are respectively installed on connecting rods 25. (Servo motor 22 is controlled by communication with frequency converter via display and control touch screen. The display and control touch screen adopts MODBUS.) The RTU protocol communicates directly with the frequency converter, enabling functions such as start, stop, forward and reverse rotation, and frequency setting. The touchscreen can monitor motor parameters such as voltage, current, and frequency in real time, providing an intuitive and convenient operation method, reducing system complexity and cost, and is suitable for precise motor control in industrial automation. The servo motor 22 is powered by a battery within the stirring rod 13 (the battery can be charged periodically).

[0049] The housing 16 is placed inside the mounting hole 15, which has a threaded hole. A limit bolt 19 is fitted inside the threaded hole (a sealing cover is designed on the side of the housing 16 away from the limit bolt 19, so that the internal components of the housing 16 can be inspected when the housing 16 is removed).

[0050] The stirring blade 18 is fitted with screws, and the connecting rod 25 has a threaded groove, with the screws fitted into the threaded groove.

[0051] An insulation layer 4 is installed on the outside of the outer shell 1. The heating pipe 6, the cooling pipe 8, the vertical pipe 10 and the temperature sensor 12 extend to the outside of the insulation layer 4. The insulation layer 4 is made of rock wool with metal material wrapped around it.

[0052] The inner wall of reactor 2 is coated with a protective coating 5. The protective coating 5 (surface treatment technology) of the inner liner of reactor 2 is formed on the surface of the inner liner of reactor 2 using technologies such as physical vapor deposition (PVD) and chemical vapor deposition (CVD) to form a high-performance coating, such as titanium nitride or tungsten carbide coating, to improve hardness and corrosion resistance. Alternatively, a special chemical treatment method can be used to form a passivation film on the metal surface to enhance corrosion resistance.

[0053] When using the temperature control and stirring optimization device for the silicone sealant production reactor, first, place the housing 16 in the center of the mounting hole 15 and tighten the limiting bolt 19 to fix it. Otherwise, it can be disassembled. Then, install the stirring blade 18 on the corresponding connecting rod 25. During operation, the silicone sealant raw material is fed into the reactor 2. The driving component on the reactor 2 drives the stirring rod 13 to rotate. At the same time, the servo motor 22 drives the double-threaded rod 23 to rotate forward and backward on the U-shaped plate 20 through the bearing, so that the moving part 24 reciprocates along the double-threaded rod 23 and the limiting groove 28. The moving part 24 drives the connecting rod 25 to move along the rubber sleeve 27. The connecting rod 25 moves the stirring blade 18, changing the stirring range of the material in the reactor 2, so that the material can be stirred evenly. At the same time, the heating pipe 6 and the cooling pipe 8 are controlled to discharge the medium, so that the material in the reactor 2 is heated or cooled. The temperature sensor can detect the material temperature and connect with the external controller. The controller can accurately control the valve operation, thereby achieving effective control of the material temperature in the reactor.
