DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments, but this does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0021] See Figure 1-Figure 2The utility model provides a safe fluid reversing system for an ink mixing tank, which includes a pneumatic diaphragm pump 2, and a gas reversing module. The pneumatic diaphragm pump 2 is connected to an external air source, and the valve body of the pneumatic diaphragm pump 2 is provided with an outlet valve port 20 and an inlet valve port 21. The outlet valve port 20 is connected to the first material port 3 of the ink mixing tank through a first pipe 10, and the inlet valve port 21 is connected to the second material port 4 of the ink mixing tank through a second pipe 11. A gas reversing module is provided between the first pipe 10 and the second pipe 11, and the outlet valve port 20 is connected to the second material port 4 of the ink mixing tank through the gas reversing module, and the inlet valve port 21 is connected to the first material port 3 of the ink mixing tank through the gas reversing module.

[0022] A first pneumatic stop valve 5 is installed in the first pipe 10, and a second pneumatic stop valve 6 is installed in the second pipe 11. The first pneumatic stop valve 5 is used to connect and disconnect the first material port 3 and the first valve port 20. The second pneumatic stop valve 6 is used to connect and disconnect the second material port 4 and the second valve port 21.

[0023] The gas reversing module includes a third pipeline 12 and a fourth pipeline 13. One end of the third pipeline 12 is connected to the first pipeline 10 located between the first pneumatic stop valve 5 and the gas outlet valve port 20, and the other end of the third pipeline 12 is connected to the second pipeline 11 located between the second pneumatic stop valve 6 and the second material port 4.

[0024] One end of the fourth pipeline 13 is connected to the first pipeline 10 located between the first pneumatic stop valve 5 and the first material port 3 , and the other end of the fourth pipeline 13 is connected to the second pipeline 11 located between the second pneumatic stop valve 6 and the air inlet valve port 21 .

[0025] A third pneumatic stop valve 7 is installed in the third pipe 12, and a fourth pneumatic stop valve 8 is installed in the fourth pipe 13. The third pneumatic stop valve 7 is used to open and close the second material port 4 and the first valve port 20. The fourth pneumatic stop valve 8 is used to open and close the first material port 3 and the second valve port 21.

[0026] One-way valves 9 are installed in the third pipeline 12 and the fourth pipeline 13 to ensure that the gas flows in the third pipeline 12 and the fourth pipeline 13 are unidirectional.

[0027] Flow sensors are installed in both the first pipe 10 and the second pipe 11. The flow sensors are electrically connected to a controller, which is in turn electrically connected to an alarm. When the pneumatic diaphragm pump 2 is operating and the controller detects a zero gas flow rate through the flow sensors, the controller controls the alarm to sound an alarm, alerting personnel to inspect the pipes and the pneumatic shut-off valve.

[0028] The air inlet of pneumatic diaphragm pump 2 is connected to an external air source through pneumatic control valve 1. An air pressure regulator is installed in the pipe connecting pneumatic diaphragm pump 2 and pneumatic control valve 1. The main function of the air pressure regulator is to regulate and control the gas pressure to ensure stable operation of the system.

[0029] The working principle of this utility model is:

[0030] like Figure 1 As shown, when gas is required to enter from the first material port 3 and exit from the second material port 4, the pneumatic control valve 1 is opened, the first pneumatic stop valve 5 and the second pneumatic stop valve 6 are opened, and the third pneumatic stop valve 7 and the fourth pneumatic stop valve 8 are closed. The gas generated by the external gas source enters the gas diaphragm pump 2 through the gas control valve 1, and the gas enters the first material port 3 from the outlet valve port 20 of the gas diaphragm pump 2 through the first pipeline 10 and the first pneumatic stop valve 5. The gas stored in the ink mixing tank enters the inlet valve port 21 of the gas diaphragm pump 2 through the second material port 4, the second pneumatic stop valve 6 and the second pipeline 11, thereby discharging the gas.

[0031] like Figure 2 As shown, when gas is required to enter from the second material port 4 and to exhaust from the first material port 3, the first pneumatic stop valve 5 and the second pneumatic stop valve 6 are closed, and the third pneumatic stop valve 7 and the fourth pneumatic stop valve 8 are opened. The gas enters the second material port 4 from the outlet valve port 20 of the gas diaphragm pump 2 through the first pipe 10, the third pneumatic stop valve 7 and the third pipe 12, and the gas stored in the ink mixing tank enters the inlet valve port 21 of the gas diaphragm pump 2 through the first material port 3, the first pipe 10, the fourth pipe 13, the fourth pneumatic stop valve 8 and the second pipe 11, thereby discharging the gas.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
