[0019] Reference Figure 1 According to this utility model, an automatic drainage centralized control management system for an air compressor storage tank 1 includes several air storage tanks 1 connected to the air compressor, a main drainage pipe 6, and a control system. The bottom of the air storage tank 1 is provided with a drainage pipe, which includes a detection section 2 and a control section 3 connected in sequence. The detection section 2 is provided with a liquid level sensor 4, and the control section 3 is provided with a solenoid valve 5 and a timer. The timer is signal-connected to the solenoid valve 5. The multiple drainage pipes are all connected to the main drainage pipe 6. The liquid level sensor 4, the solenoid valve 5, and the timer are all signal-connected to the control system.

[0020] It is understood that the automatic drainage centralized control management system for air compressor storage tank 1 provided in this utility model embodiment automatically detects the condensate level in storage tank 1 through a liquid level sensor 4 and a timer, and automatically opens and closes the solenoid valve 5 for drainage in conjunction with the control system. This replaces the traditional manual timed inspection and manual drainage method, significantly reducing the labor intensity of workers and avoiding human error. The drainage devices of multiple storage tanks 1 are uniformly connected to the control system, and centralized monitoring and parameter setting can be achieved through interfaces such as touch screens. The drainage status of each storage tank 1 can be grasped in real time, improving management efficiency and system visualization. The control strategy of combining "timed drainage" and "liquid level detection" can automatically drain water according to a set cycle, and can also respond immediately when water accumulation is detected, ensuring that condensate is drained in time, improving the accuracy and reliability of drainage. This utility model embodiment can effectively remove condensate in a timely manner, reduce the corrosion of pneumatic components by moisture, reduce equipment failure rate, extend the service life of storage tank 1 and downstream air-using equipment, ensure the stable operation of the production system, and realize intelligent and centralized management of drainage of air compressor storage tank 1. It has the advantages of stable operation, convenient maintenance, safety and efficiency.

[0021] Furthermore, according to some embodiments of this utility model, the control system includes a touch screen and an alarm, and the liquid level sensor 4, solenoid valve 5, timer and alarm are all connected to the touch screen for signal connection.

[0022] Understandably, by setting up touchscreens and alarms connected to the signals of each component in the control system, centralized visual operation and real-time status monitoring of the system are achieved. Operators can intuitively view the drainage operation of each gas storage tank 1 through the touchscreen, and when the liquid level is abnormal or the equipment malfunctions, the alarm will issue an audible and visual alarm signal, while displaying specific fault information on the touchscreen, which facilitates quick problem location and improves maintenance efficiency and system safety.

[0023] Furthermore, according to some embodiments of the present invention, the touch screen is provided with a manual drain button that is signal-connected to the solenoid valve 5.

[0024] Understandably, the inclusion of a manual drain button on the touchscreen, connected to the signal of solenoid valve 5, provides convenient manual intervention for the system. Inspection personnel can initiate drainage with a single touchscreen without needing to physically operate the valve, facilitating routine inspections, testing, and emergency response. This enhances operational flexibility and safety while further reducing reliance on manual on-site operations.

[0025] Furthermore, according to some embodiments of the present invention, a drainage bypass 7 is provided between the detection section 2 and the main drainage pipe 6, and the drainage bypass 7 is provided with a first manual valve 8.

[0026] It is understandable that a drainage bypass 7 with a first manual valve 8 is added between the detection section 2 and the main drainage pipe 6. When the main drainage passage (such as solenoid valve 5) is under maintenance or malfunctions, the bypass can be opened to manually drain water, ensuring that the gas storage tank 1 can still drain normally during system maintenance, avoiding the accumulation of condensate due to maintenance, and improving the reliability and maintainability of the system.

[0027] Preferably, according to some embodiments of the present invention, the liquid level sensor 4 includes a tuning fork level gauge.

[0028] Understandably, a tuning fork level gauge is a liquid level switch tool designed using the tuning fork principle. Its switching principle relies on the resonance of a piezoelectric crystal to induce vibration, offering advantages such as simple structure, fast response speed, and strong anti-interference capability. Tuning fork level gauges are suitable for high-pressure, high-temperature industrial environments and can operate stably under complex conditions where compressed air and condensate coexist, ensuring accurate level detection and long-term operational reliability.

[0029] Preferably, according to some embodiments of the present invention, the liquid level sensor 4 includes a high liquid level sensor 4 and a low liquid level sensor 4.

[0030] Understandably, by setting up a dual-level detection structure with high-level sensor 4 and low-level sensor 4, graded control of the condensate level in the gas storage tank 1 can be achieved. When the water level reaches the high level, drainage is automatically started, and drainage stops when the water level drops to the low level, avoiding frequent opening and closing of the solenoid valve 5, extending the equipment life, and achieving more precise drainage control to prevent incomplete or excessive drainage.

[0031] Furthermore, according to some embodiments of the present invention, the detection section 2 is provided with a second manual valve 9.

[0032] Understandably, the second manual valve 9 is installed in detection section 2 to isolate the level sensor 4 for maintenance or replacement without affecting the operation of other parts of the drainage system. This design improves system maintainability, ensures basic drainage function during sensor failure or calibration, and enhances system flexibility and safety.

[0033] Furthermore, according to some embodiments of the present invention, the gas storage tank 1 is provided with a safety valve 10.

[0034] It is understandable that installing a safety valve 10 on the gas storage tank 1 can automatically release pressure when the system pressure rises abnormally, preventing safety accidents such as explosions caused by overpressure. As an important safety protection device, the safety valve 10 effectively improves the operational safety and reliability of the entire automatic drainage system, meeting the requirements of pressure vessel safety regulations.

[0035] Furthermore, according to some embodiments of this utility model, the control system is a PLC.

[0036] Understandably, by employing a PLC (Programmable Logic Controller) as the control system, precise, stable, and efficient control of the automatic drainage process of multiple air compressor storage tanks 1 is achieved. The PLC possesses advantages such as strong anti-interference capability, stable operation, flexible programming, and easy expansion. It can reliably receive signals from the level sensor 4 and the timer, and accurately output control commands to drive the solenoid valve 5, ensuring accurate execution of the drainage logic and adapting to the long-term operational needs of complex industrial environments.

[0037] Furthermore, according to some embodiments of this utility model, the output end of the main drain pipe 6 is connected to a liquid recovery device 11. Specifically, the liquid recovery device 11 includes, but is not limited to, a condensate collection tank, an oil-water separator, an automatic drainer, a sewage pretreatment system, and a condensate recovery and reuse system.

[0038] Understandably, connecting a liquid recovery device 11 to the output end of the main drain pipe 6 allows for the centralized collection and treatment of discharged condensate. This avoids problems such as slippery floors, equipment corrosion, and environmental pollution caused by indiscriminate discharge of condensate, improving site cleanliness and safety. Furthermore, the treated condensate can be further used for non-high-quality water applications such as equipment cooling and factory cleaning, achieving water resource recycling and meeting the requirements of green production and energy conservation and emission reduction.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
