Background technique

The Yellow River Crossing Project of the Middle Route of the South-to-North Water Diversion Project is a water conservancy project that crosses large rivers. It is a symbolic and controllable project of the entire middle route of the South-to-North Water Diversion Project. (In the implementation of the ecological water ecological regulation test project of the middle line of the South-to-North Water Diversion Project, in order to increase the oxygen content of the water body in the aquaculture area, our factory uses the siphon principle technology to transport the water body in the aquaculture area) in this way. The method consumes less energy, is easy to implement, and is easy to operate, but the siphon water transfer also has certain defects. For example, when the water body reaches the height above the water surface of the siphon inlet, the air dissolved in the water will be released. The highest point is collected, and when the air bubbles reach a certain level, the siphon will be interrupted.

The bottom of the water storage tank is connected with the highest point of the siphon pipe through the gas-liquid exchange pipe. The height of the water storage tank is higher than the siphon pipe, and the gas-liquid exchange pipe is provided with The second electric control valve, the top of the water storage tank is connected with the highest point of the exhaust pipe, and the third electric control valve is on the exhaust pipe.

The water storage tank is also connected with a transparent liquid level observation pipe, which is arranged in the vertical direction, the upper end of the liquid level observation pipe is connected to the upper part of the water storage tank, and the lower end of the liquid level observation pipe is connected to the bottom of the water storage tank. In the lower part, a high liquid level sensor is arranged at the connection between the upper end of the liquid level observation pipe and the upper part of the water storage tank, and a low liquid level sensor is arranged at the connection between the lower end of the liquid level observation pipe and the lower part of the water storage tank.

At the connection between the gas-liquid exchange pipe and the siphon pipe, the gas-liquid exchange pipe is in the shape of a bell mouth.

By adopting the above technical scheme, the utility model has the following beneficial effects: when the utility model works, the siphon principle is used, and the high-level water tank supplies water to the low-level water tank through the siphon pipe. The second electric control valve is in the open state, the bubbles generated in the siphon pipe rise to the water storage tank through the gas-liquid exchange pipe, and the water in the water storage tank flows into the low-level water tank through the siphon pipe;

As the air in the siphon is exchanged with the water in the water storage tank, the water level in the water storage tank can be observed continuously dropping through the observation tube. When the water level in the water storage tank drops to the low level sensor, the low liquid level The position sensor sends a signal, the second electric control valve is closed, the first electric control valve and the third electric control valve are opened, the water pump starts to work, and the water in the water tank is pumped into the water storage tank, and the gas in the water storage tank is discharged. The air pipe is discharged to the outside; when the water level in the water storage tank reaches the high liquid level sensor, the water pump stops working, the second electric control valve is opened, the first electric control valve and the third electric control valve are closed, and the siphon continues to enter the working state.

To sum up, the utility model has the advantages of simple structure and convenient operation, which can timely and effectively discharge the air bubbles in the siphon pipe, realize gas-liquid exchange, and thus complete the continuous water body transportation of the siphon pipe.

Detailed ways

As shown in FIG. 1 , the siphon gas-liquid exchange device of the present invention includes a water tank 1, a water storage tank 2, a high-level water tank 3 and a low-level water tank 4. The high-level water tank 3 is connected to the low-level water tank 4 through a siphon 5, and the water tank 1 is connected by a water supply pipe. 6 is connected to the top of the water storage tank 2, the water supply pipe 6 is provided with a water pump 7 and a first electric control valve 8, the bottom of the water storage tank 2 is connected to the highest point of the siphon 5 through the gas-liquid exchange pipe 9, and the water storage tank 2 The height of the siphon is higher than the highest point of the siphon 5. The gas-liquid exchange pipe 9 is provided with a second electronically controlled valve 10, the top of the water storage tank 2 is connected with an exhaust pipe 11, and the exhaust pipe 11 is provided with a third electronically controlled valve 12.

The water storage tank 2 is also connected with a transparent liquid level observation pipe 13, the liquid level observation pipe 13 is arranged in the vertical direction, the upper end of the liquid level observation pipe 13 is connected to the upper part of the water storage tank 2, and the lower end of the liquid level observation pipe 13 is connected.
