Description

Technical Field

[0001] This application relates to the field of air compressor technology, and more specifically, to a drain system for an air compressor cooler. Background Technology

[0002] The cooler is an important component of the air compressor system. Through the principle of heat exchange, the cooler transfers heat from the air compressor system to cooling water or other cooling media to maintain the temperature during normal operation of the air compressor. In this process, a large amount of condensate will be generated. As a key component for water discharge from the cooler, the performance of the steam trap directly affects the stable operation and energy efficiency of the air compressor.

[0003] Existing steam traps typically use traditional float control. When the water level in the steam trap causes the float to rise, the steam trap opens and begins to drain water. Over time, the valve body corrodes and the valve fails to function properly. In the absence of water or with only a small amount of water, the valve core remains open for an extended period, resulting in the discharge of a large amount of air. This reduces the amount of air delivered by the air compressor and increases production costs. Utility Model Content

[0004] The purpose of this application is to provide a drain system for an air compressor cooler, which enables automatic control of draining water from the air compressor system and reduces energy consumption.

[0005] This application provides a drain system for an air compressor cooler, employing the following technical solution:

[0006] A condensate drain system for an air compressor cooler includes a cooler, a condensate container, and a controller. An inlet pipe is provided between the cooler and the condensate container. A high-level sensor and a low-level sensor are installed inside the condensate container. The condensate container is connected to a drain pipe, and a first electrically controlled valve is installed on the drain pipe. The high-level sensor, the low-level sensor, the first electrically controlled valve, and the controller are electrically connected.

[0007] The inlet pipe is equipped with a first manual valve;

[0008] A Y-type filter is installed on the inlet pipe;

[0009] A first branch pipe is provided on the liquid inlet pipe, the first branch pipe is located between the first manual valve and the cooler, and a second manual valve is provided on the first branch pipe.

[0010] Preferably, the hydrophobic container is equipped with a level transmitter.

[0011] Preferably, a second branch pipe is provided on the drain pipe, and a second electrically controlled valve is provided on the second branch pipe.

[0012] Preferably, the hydrophobic container is provided with a return air pipe.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] This application uses a hydrophobic container to collect condensate from the air compressor cooler. When the liquid level rises to the high level of the hydrophobic container, the high level sensor sends a signal to the controller, which then controls the first electrically controlled valve to open, causing the liquid level inside the hydrophobic container to begin to drop. When the liquid level drops to the low level of the hydrophobic container, the low level sensor sends a signal to the controller, which then controls the first electrically controlled valve to close. At this point, there is still liquid below the low level, ensuring that the hydrophobic container only drains water and does not release gas, thus preventing the waste of compressed air from the air compressor.

[0025] Example

[0026] like Figure 1 As shown in the embodiment of this application, the air compressor cooler drainage system includes a cooler 1, a drainage container 2, and a controller. An inlet pipe 3 is provided between the cooler 1 and the drainage container 2. A high liquid level sensor 4 and a low liquid level sensor 5 are provided inside the drainage container 2. The drainage container 2 is connected to a drain pipe 6. A first electrically controlled valve 7 is provided on the drain pipe 6. The high liquid level sensor 4, the low liquid level sensor 5, the first electrically controlled valve 7 are electrically connected to the controller.

[0027] In use, the condensate in the air compressor cooler 1 is collected through the hydrophobic container 2. When the liquid level rises to the high level of the hydrophobic container 2, the high level sensor 4 sends a signal to the controller, which controls the first electrically controlled valve 7 to open, and the liquid level inside the hydrophobic container 2 begins to drop. When the liquid level drops to the low level of the hydrophobic container 2, the low level sensor 5 sends a signal to the controller, which controls the first electrically controlled valve 7 to close. At this time, there is still liquid below the low level, which ensures that the hydrophobic container 2 only drains water and does not exhaust gas, thus avoiding waste of compressed air from the air compressor.

[0028] In this embodiment, a first manual valve 8 is provided on the liquid inlet pipe 3. By providing the first manual valve 8, it is convenient to control the flow of liquid inside the liquid inlet pipe 3.

[0029] In this embodiment, a Y-type filter 9 is provided on the liquid inlet pipe 3. The Y-type filter 9 has the advantages of simple manufacturing, convenient installation and cleaning, and large dirt holding capacity. It is used to remove impurities in the water and reduce the maintenance frequency of the hydrophobic container 2.

[0030] In this embodiment, a first branch pipe 10 is provided on the liquid inlet pipe 3. The first branch pipe 10 is located between the first manual valve 8 and the cooler 1. A second manual valve 11 is provided on the first branch pipe 10. When in use, the second manual valve 11 is kept closed. When it is necessary to maintain the Y-type filter 9 and the hydrophobic container 2, the first manual valve 8 is closed and the second manual valve 11 is opened to discharge the condensate through the first branch pipe 10.

[0031] In this embodiment, a level transmitter 12 is installed on the hydrophobic container 2. The level transmitter 12 has the characteristics of easy installation, high measurement accuracy and long service life. The liquid level inside the hydrophobic container 2 can be viewed on site through the level transmitter 12. After the level transmitter 12 sends the signal to the controller, the opening degree of the first solenoid valve 7 can be controlled according to the different liquid levels.

[0032] In this embodiment, a second branch pipe 13 is provided on the drain pipe 6, and a second electrically controlled valve 14 is provided on the second branch pipe 13. When the first electrically controlled valve 7 needs maintenance, the second electrically controlled valve 14 is opened, and the water is drained through the second branch pipe 13.

[0033] In this embodiment, a return pipe 15 is provided on the hydrophobic container 2. The return pipe 15 is used to discharge the gas inside the hydrophobic container 2 to prevent the condensate from entering the hydrophobic container 2 due to excessive gas pressure.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
