When the communicating pipe 7 slowly deposits sludge, the water quantity in the communicating pipe 7 is reduced, the liquid level difference between the coagulation area 1 and the flocculation area 2 is increased, and after the liquid level difference reaches a certain value, the PLC controller sends a signal to control the automatic valve to open. Specifically, the first liquid level meter 3 in the coagulation area 1 and the second liquid level meter 5 in the flocculation area 2 send the measured liquid level values to the PLC controller, the PLC controller calculates the liquid level differences of the first liquid level meter 3 and the second liquid level meter 5, if the liquid level differences reach a certain value, the PLC controller controls the compressed air valve 12 to be opened for 2-3min and then controls the water flushing valve 13 to be opened for 2-3min, then controls the compressed air valve 12 and the water flushing valve 13 to be simultaneously opened for 3-5min, in the process, the PLC controller continuously receives signals sent back by the two liquid level meters 3, if the liquid level differences are reduced to an allowable range, the PLC controller controls the compressed air valve 12 and the water flushing valve 13 to be simultaneously closed, if the liquid level differences are not reduced or are not reduced to a great extent, the situation that the sludge at the bottom of the communicating pipe can be judged, the PLC controller controls the compressed air valve 12 and the water flushing valve 13 to be simultaneously closed and controls the medicine adding valve 14 to be opened for 2-3min, if the liquid level differences are reduced to be reduced to an allowable range, the PLC controller controls the medicine adding valve 14 to be simultaneously closed, if the liquid level differences are not reduced to be reduced, and the bottom of the communicating pipe is not is pumped out, and the communicating pipe is not opened, and the negative pressure is not is controlled to be normally opened, and the communicating pipe is not is pumped to be opened, and the bottom by the communicating pipe is left to be 3 is left to be opened, and the communicating pipe is left to be left to a left.
When the sludge at the bottom of the communicating pipe 7 is gradually cleared, the water flow in the pipe is restored to the initial state, the liquid level difference between the coagulation area 1 and the flocculation area 2 is reduced, and after the liquid level difference received by the PLC is reduced to a certain value, the PLC controls the negative pressure suction valve 15 to be closed, and the high-density sedimentation tank is restored to the normal operation state, so that the circulation is performed. The control principle among the liquid level meter, the PLC controller and the valve belongs to the prior art and is not repeated here.
The automatic flushing system can effectively solve the problem of blockage of the communicating pipe of the high-density sedimentation tank, is simple, economical and energy-saving, does not need extra occupied area, is convenient to overhaul and maintain, does not need personnel on duty, reduces maintenance cost, and enables the high-density sedimentation tank to stably operate for a longer time.
