Description

Technical Field

[0001] This utility model belongs to the field of silicone safety monitoring, specifically relating to a cooling circulation control and monitoring system applied to a sealant production line. Background Technology

[0002] The production of silicone sealants involves high-speed screw mixing, during which the materials often reach very high temperatures. To maintain the required constant temperature for the process, the materials need to be cooled. In the sealant production process, the cooling circulation system plays a crucial role in ensuring product quality and the stability of the production process. With the continuous advancement of industrial automation and the increasing trend towards less-staffed factory operations, higher demands are being placed on the management and control of cooling circulation systems.

[0003] Traditional sealant production line cooling circulation systems have numerous limitations. Their control methods largely rely on a combination of manual on-site operation and simple local automation. Under this control model, when workers temporarily leave their posts for meals, restroom breaks, or other reasons, the operating status of the cooling circulation system is difficult to monitor effectively. For example, if the cooling tower experiences an emergency such as a rapid drop in liquid level, a sharp rise in temperature, or abnormal fluctuations in refrigeration unit pressure during operation, the lack of timely remote monitoring and early warning mechanisms means these problems may not be detected and addressed in time. This could potentially lead to production interruptions, serious equipment damage, or even accidents endangering personnel safety, posing a significant threat to the company's production efficiency and safety.

[0004] Therefore, there is currently a lack of a safe and reliable cooling circulation control and monitoring system for use in sealant production lines. Utility Model Content

[0028] 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.

[0029] This embodiment describes a cooling circulation control and monitoring system applied to a sealant production line, such as... Figure 1 As shown, it includes: a cooling system, a near-central control room, a remote central control room, and handheld alarm equipment.

[0030] The cooling system includes: a cooling tower 1, a cooling water tank 2, a chiller unit 3, and a low-temperature chilled water tank 4. (See also...) Figure 2 This diagram illustrates the cold water transfer process in a cooling system. The production line manufactures silicone sealant products and utilizes a high-speed twin-spiral agitator, generating significant heat. The cooling system supplies cold water to the production line for cooling. The water in the cooling system is recycled.

[0031] Cooling tower 1 is used to cool cooling water tank 2. Cooling water tank 2 continuously supplies chilled water to low-temperature chilled water tank 4 through chiller unit 3. Cooling water tank 2 provides cooling water to chiller unit 3, and its water temperature is required to be between 25-30 degrees Celsius. The chilled water in low-temperature chilled water tank 4 is used to directly supply circulating chilled water to the production line.

[0032] Cooling tower 1 is used to dissipate heat from the cooling medium. It is equipped with a cooling tower level sensor and a cooling tower temperature sensor to monitor the liquid level and cooling medium temperature, respectively, and transmit the relevant data to the first DCS control system. Cooling water tank 2 is equipped with a cooling water tank level sensor to monitor the liquid level in real time and feed it back to the first DCS control system. Low-temperature chilled water tank 4 is equipped with a low-temperature chilled water level sensor and a low-temperature chilled water pressure sensor to monitor the liquid level and pressure, providing data to the first DCS control system for precise regulation of the entire cooling system's operation.

[0033] Near the central control room are: the first DCS control system, the first remote communication module, transmission lines, and the first alarm module.

[0034] The system comprises a first DCS control system, a first remote communication module, a transmission line, a first alarm module, a first database module, a second database module, and a backup power supply. The first DCS control system, as the core control unit, receives data from various sensors in the cooling system and controls equipment such as the chiller unit 3 according to preset programs and process requirements. For example, when the temperature of cooling tower 1 is too high or the liquid level in cooling water tank 2 is too low, the first DCS control system can adjust the cooling power of chiller unit 3 or activate the water replenishment device accordingly. The first remote communication module is responsible for data interaction with the second remote communication module in the remote control room and the third remote communication module of the handheld alarm device, enabling remote data transmission and sharing. The transmission line connects the cooling system to the near control room, ensuring stable data transmission. The first alarm module issues audible and visual alarm signals when system abnormalities occur, promptly alerting operators in the near control room. The first and second database modules receive and store various data from the cooling system, including historical operating parameter data and fault records, for subsequent data analysis, production process optimization, and troubleshooting. The backup power supply automatically starts when the external power supply fails, providing power support for critical equipment near the central control room and ensuring the continuous operation of the system.

[0035] The remote control room includes: a second DCS control system, a second remote communication module, and a second alarm module.

[0036] The second DCS control system can receive data from the central control room and remotely operate and monitor the first DCS control system in the central control room, enabling remote collaborative management. The second remote communication module establishes a data connection channel with the first remote communication module to ensure bidirectional data transmission. The second alarm module issues an audible and visual alarm upon receiving abnormal data or remote operation commands, alerting personnel in the remote control room.

[0037] Handheld alarm device, including: control unit, third remote communication module and third alarm module;

[0038] It should be noted that staff members wear handheld alarm devices.

[0039] The third remote communication module enables data communication between the handheld alarm device and the first and second remote communication modules, ensuring that operators can receive system alarm information and operational data in a timely manner even when located far from the central control room. The third alarm module emits an audible and visual alarm upon receiving an abnormal signal, alerting on-site personnel.

[0040] In practical applications, the cooling tower liquid level sensor, cooling tower temperature sensor, cooling water pool liquid level sensor, low-temperature chilled water pool liquid level sensor, and low-temperature chilled water pool pressure sensor are all preset with corresponding thresholds. When the first DCS control system or the second DCS control system detects that the threshold is exceeded, the first alarm module of the first DCS control system, the second alarm module of the second DCS control system, and the third alarm module of the second DCS control system all generate alarms.

[0041] Furthermore, handheld alarm devices also include a display and a fingerprint recognition module.

[0042] The display visually shows key operating parameters of the cooling system, allowing operators to easily check them at any time. The fingerprint recognition module enhances security, ensuring only authorized personnel can activate and operate the handheld alarm device via fingerprint recognition.

[0043] The cooling system is connected to the central control room via a transmission line; the first remote communication module is connected to the second and third remote communication modules respectively.

[0044] The cooling system is connected to the near-central control room via a transmission line to enable data transmission and control command issuance. The first remote communication module is connected to the second and third remote communication modules respectively, forming a remote data interaction network for the entire system, enabling real-time data sharing and collaborative operation between the near-central control room, the remote central control room, and the handheld alarm devices.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
