Description

Technical Field

[0001] This utility model relates to the technical field of temperature regulation and monitoring equipment, specifically an automatic temperature regulation and monitoring device. Background Technology

[0002] Automatic temperature control and monitoring systems are crucial control systems in power plant steam and water sampling control systems. They maintain a constant temperature for the sample water and provide real-time adjustment for samples that are too hot or too cold, thus improving the stability and accuracy of downstream chemical instrument measurements and attracting increasing attention. However, existing control systems of this type still have shortcomings, such as:

[0003] 1. Centralized water-cooled constant temperature devices are generally large in size. They can centrally control multiple water samples, but the adjustment is relatively coarse and cannot accurately and in real time adjust a single water sample, resulting in a high degree of lag.

[0004] 2. Centralized air-cooled constant temperature devices have the same disadvantages as centralized water-cooled constant temperature devices. They centrally control multiple water samples, resulting in relatively coarse adjustments. They cannot accurately and in real time adjust a single water sample, exhibiting high lag. They also generate significant noise and power consumption.

[0005] Therefore, we need to propose an automatic temperature regulation and monitoring device. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1 This utility model provides a technical solution:

[0026] An automatic temperature regulation and monitoring device includes:

[0027] The main structure includes a cooler 1, a thermostatic control valve 6, and a monitoring panel 10. The cooler 1 has an inlet pipe 3 and a return pipe 4 connected to its cooling water inlet and outlet ends, respectively. The cooler 1 has a main pipe 2 for inputting sample water connected to its liquid inlet end, and a cooling pipe 5 for outputting sample water connected to its liquid outlet end.

[0028] The thermostatic control valve 6 includes two sets of inlet ends and one set of outlet ends. The two sets of inlet ends of the thermostatic control valve 6 are respectively connected to one end of the cooling pipe 5 and the branch pipe 7 for conveying sample water. The outlet end of the thermostatic control valve 6 is connected to a thermostatic pipe 8 for conveying thermostatic sample water. The sample water in the main pipe 2 is cooled by the cooler 1 and then enters the thermostatic control valve 6 and mixes with the original temperature sample water in the branch pipe 7 to reach the required temperature and is conveyed through the thermostatic pipe 8.

[0029] The thermostatic tube 8 is equipped with a temperature measuring zone, and a temperature sensor 9 is installed in the temperature measuring zone to detect the temperature of the output sample water. A monitoring panel 10 is installed on one side of the temperature measuring zone to monitor the temperature.

[0030] The monitoring panel 10 has a built-in PLC processor and includes a display screen and control buttons. The monitoring panel 10, the thermostatic control valve 6, and the temperature sensor 9 are connected by cables.

[0031] The cooling water inlet and outlet pipes of cooler 1 are connected to cooling water inlet pipe 3 and cooling water return pipe 4 by threads. The thermostatic control valve 6 is connected to the main sample water line (cooling pipe 5) passing through cooler 1 and the sample water bypass line (branch pipe 7) not passing through cooler 1. The mixed sample water is output through thermostatic pipe 8. Temperature sensor 9 is connected to the temperature measurement area of ​​thermostatic pipe 8 and uses threaded connection to detect the temperature of the sample water transported in the temperature measurement area. The monitoring panel 10 is connected to thermostatic control valve 6 and temperature sensor 9 by cables, and sends signals to remote control system and local control system as needed by the project.

[0032] The work steps are as follows:

[0033] 1. Cooling water provides a cold source for cooler 1;

[0034] 2. The high-temperature sample water from the main sample water pipeline is transported through the main pipeline 2 and cooled by the cooler 1 to obtain low-temperature sample water. This low-temperature sample water is then mixed with the low-temperature sample water from the bypass pipeline (which is transported to the thermostatic control valve 6 through the branch pipeline 7) in the thermostatic control valve 6 to obtain sample water at the required temperature.

[0035] 3. Temperature sensor 9 monitors the sample water temperature output by thermostatic control valve 6 in real time (located in the temperature measurement area of ​​thermostatic tube 8) and transmits the temperature signal to monitoring panel 10.

[0036] 4. The monitoring panel 10 displays the real-time temperature based on the temperature signal measured by the temperature sensor 9, and adjusts the opening of the thermostatic control valve 6 in real time to adjust the inflow of high and low temperature sample water respectively, so as to realize the function of real-time adjustment of sample water temperature. When the sample water exceeds the temperature, it outputs an alarm signal to realize remote alarm function (wireless transmission module), local alarm (alarm horn) and control function.

[0037] In summary, through the cooperation of cooler 1, thermostatic control valve 6, temperature sensor 9 and monitoring panel 10, compared with the traditional temperature control method, it has the advantages of automated operation, intelligent monitoring, and simple operation. It is convenient for centralized management, saves human resources, and has mature technical principles, high system integration, and excellent performance. It has low noise and energy consumption, small size, precise control of each sample water, high sensitivity, no adjustment lag, and reliable operation.

[0038] Example:

[0039] In power plants, the optimal measurement temperature for chemical analysis instruments is 25℃. After a single-channel sample water undergoes primary cooling, it is generally around 50℃, while the system cooling water temperature is generally 4.4℃. At this point, the sample water is required to reach 25℃ after passing through the "automatic temperature regulation and monitoring equipment".

[0040] 1. Cooling water at 4.4℃ provides a cold source for cooler 1;

[0041] 2. In the main sample water pipeline, the high-temperature sample water at around 50°C passes through cooler 1 and exchanges heat fully with the 4.4°C cooling water through the heat pipe inside cooler 1, resulting in low-temperature sample water at a lower temperature, which then flows into the thermostatic control valve 6.

[0042] 3. In the sample water bypass, the high-temperature sample water at about 50°C that has not been cooled by the cooler 1 flows into the thermostatic control valve 6 at the same time. It mixes thoroughly with the low-temperature sample water that has been cooled by the cooler 1 in the main sample water line. According to the heat exchange law, after the high and low temperature sample waters exchange heat, the temperature of the mixed sample water is between the temperature ranges of the two.

[0043] 4. The temperature sensor 9 monitors the sample water temperature output by the thermostatic control valve 6 in real time and transmits the temperature signal to the monitoring panel 10. The monitoring panel 10 displays the sample water temperature in real time and compares the temperature with the required 25℃ temperature value.

[0044] 5. When the temperature measured by temperature sensor 9 is higher than the required 25℃, monitoring panel 10 controls thermostatic control valve 6 to increase the opening of one side of cooling pipe 5, thereby increasing the flow rate of low-temperature sample water and thus reducing the temperature of the mixed sample water until the sample water temperature reaches 25℃. Similarly, when the temperature measured by temperature sensor 9 is lower than the required 25℃, monitoring panel 10 controls thermostatic control valve 6 to decrease the opening, thereby reducing the flow rate of low-temperature sample water and thus increasing the temperature of the mixed sample water until the sample water temperature reaches 25℃, realizing the automatic temperature regulation function of single-channel sample water.

[0045] 6. When the sample water temperature measured by temperature sensor 9 reaches the alarm temperature, monitoring panel 10 sends alarm signals H1 and H2 to the outside world. The alarm signals can be transmitted to the remote control system or the local control system as needed, realizing the remote alarm function and the local alarm and control function for sample water over-temperature.

[0046] Cooler 1 can be a shell-and-tube cooler, specifically a GLC series cooler with a working temperature ≤100℃ and a working pressure ≤1.6MPa, generally with a working pressure ≤1MPa.

[0047] For a preferred embodiment, please refer to Figure 1-2 :

[0048] The monitoring panel 10 is also equipped with an openable cover 11. An alarm horn is installed on the monitoring panel 10 below the display screen. The cover 11 has corresponding holes for sound transmission. The monitoring panel 10 has a built-in wireless transmission module to realize remote alarm and local alarm and control functions.

[0049] The alarm horn (volume ≥80dB) below the display screen of the monitoring panel 10 is triggered by the PLC to sound an alarm when the temperature sensor 9 detects over-temperature (such as deviation from the target value ±3℃). The openable cover 11 is connected to the monitoring panel 10 via a hinge. When closed, it protects the display screen and control buttons from dust and moisture corrosion. The holes on the cover 11 ensure that the alarm sound is transmitted without obstruction. The built-in wireless transmission module (supports 4G / industrial Ethernet) simultaneously transmits the alarm signal (H1 / H2) to the remote control system when the temperature exceeds the limit, and also links the local equipment to form a dual mechanism of "local sound and light alarm + remote signal warning".

[0050] The fast over-temperature response time avoids the impact of abnormal sample water temperature on detection or the occurrence of safety hazards; the cover plate 11 protects and extends the service life of the monitoring panel 10; wireless transmission enables remote monitoring without the need for on-site manual supervision, saving manpower, and is especially suitable for the centralized management needs of large-scale pipelines in power plants.

[0051] For a preferred embodiment, please refer to Figure 1-3 :

[0052] A fixing plate 13 is fixed to the temperature measuring area of ​​the thermostatic tube 8 by a clamp. A slot 14 is provided on one side of the fixing plate 13. The upper and lower ends of the monitoring panel 10 are provided with retaining edges 12. The retaining edges 12 and the slot 14 are adapted to allow the fixing plate 13 and the monitoring panel 10 to be quickly plugged in and out. The wiring harness of the monitoring panel 10 is located on its side wall so as not to hinder the assembly and disassembly of the monitoring panel 10 and the fixing plate 13.

[0053] The fixing plate 13 is fixed to the temperature measuring area of ​​the thermostatic tube 8 by clamps to ensure stable installation; the slot 14 on one side of the fixing plate 13 is adapted to the upper and lower edge clips 12 of the monitoring panel 10 (fitting gap ≤0.5mm). During installation, the edge clips 12 are directly inserted into the slot 14 to achieve quick docking between the monitoring panel 10 and the fixing plate 13; the wiring harness of the monitoring panel 10 is arranged on the side wall to avoid interference with the slot 14 during disassembly and assembly, and the wiring harness uses waterproof connectors (IP67), so there is no need to disconnect the wires when plugging and unplugging.

[0054] The monitoring panel 10 can be disassembled and assembled without tools, greatly reducing installation time compared to traditional bolt fixing. Disassembly is quick and significantly improves the efficiency of later maintenance (such as panel inspection and replacement). The clamp fixing is compatible with constant temperature tubes 8 of different diameters, and the wiring harness sidewall arrangement avoids the risk of line damage.

[0055] For a preferred embodiment, please refer to Figure 1-3 :

[0056] A U-shaped plate 15 is provided on one side of the top of the fixed plate 13. A connecting rod 16 is slidably inserted into the U-shaped plate 15. A stop 17 is provided on the connecting rod 16 between the top of the U-shaped plate 15 and the fixed plate 13. A compression spring 18 is sleeved on the connecting rod 16 between the stop 17 and the top of the U-shaped plate 15. A pull ring 19 is provided at the upper end of the connecting rod 16. The lower end of the connecting rod 16 passes through the fixed plate 13 and extends into the slot 14. When the pull ring 19 is pulled to insert the monitoring panel 10 into the slot 14, the positioning hole and the lower end of the connecting rod 16 are aligned. After the pull ring 19 is released, the lower end of the connecting rod 16 is inserted into the positioning hole to position the monitoring panel 10.

[0057] Pulling the pull ring 19 causes the connecting rod 16 to slide upward, compressing the spring 18 (elastic coefficient 6-8 N / mm) and causing the lower end of the connecting rod 16 to exit from the slot 14. Insert the monitoring panel 10 into the slot 14 with the locking edge 12 until the positioning hole on the side wall of the panel is aligned with the lower end of the connecting rod 16. Release the pull ring 19, and the spring returns to its original position, pushing the connecting rod 16 downward into the positioning hole (insertion depth ≥ 5 mm). The panel position is locked by the cooperation between the connecting rod 16 and the positioning hole.

[0058] To prevent the monitoring panel 10 from falling off due to vibration or accidental collision, and to ensure stable signal transmission of the monitoring panel 10; the pull ring 19 design makes unlocking easy and can be completed by a single person, further optimizing maintenance convenience.
