Abstract
A micro-nano aeration device with a liquid level protection function comprises an electric control unit, a gas-liquid mixing unit, a water conveying pipeline element combination, a gas conveying pipeline element combination and the like which are arranged in a machine shell. The system is started or stopped by a button signal on the control panel; the start and stop of the system are controlled through the network signals transmitted by the 4G communication module, so that whether the water pump normally operates or not is judged; and whether the water conveying pipeline is blocked or not can be judged by detecting whether the ultrasonic liquid level sensor has a liquid level signal or not. If the liquid level signal exists, the water conveying pipeline is normal, and after time delay, the electromagnetic valve and the air source relay are opened, so that the air source inputs air into the high-pressure dissolved air tank through the flowmeter and the electromagnetic valve and enters a normal operation state. If no micro signal exists, the water conveying pipeline is blocked, the system sends out a fault alarm, and a liquid level fault alarm signal is sent to the remote terminal through the 4G communication module; and then, an air source relay is disconnected to close the electromagnetic valve and cut off the air path, and after delaying for 30s, the operation of the water pump is stopped through the contactor.
