Without further limitation. The use of the phrase "comprising one of the elements" does not exclude the presence of other like elements in the process, method, article, or apparatus that comprises the element.
Please refer to fig. 1, which illustrates an embodiment of the present invention.
A automated inspection blowback dredging system for sewage treatment station sludge conduit, including sludge impoundment 1 and sedimentation tank 2, through sludge conduit 3 intercommunication, stretch into between sludge impoundment 1 and the sedimentation tank 2 be equipped with sludge pump 4 on the sludge conduit 3 of sludge impoundment 1.
The sludge treatment system is characterized by further comprising a PLC (programmable logic controller) 5, an air compressor 6, a pressure transmitter 7, a flow switch 8 and a solenoid valve 10, wherein the pressure transmitter 7, the flow switch 8 and the solenoid valve 10 are all fixed on the sludge pipeline 3, specifically, the pressure transmitter 7 is arranged on the sludge pipeline 3 and is close to the sludge tank 1, the solenoid valve 10 is arranged on the sludge pipeline 3 and is close to the sedimentation tank 2, and the flow switch 8 is arranged on the sludge pipeline 3 between the pressure transmitter 7 and the solenoid valve 10; pressure transmitter 7, flow switch 8 and solenoid valve 10 all are connected with PLC controller 5 electricity, have electric actuator 11 on the solenoid valve 10 certainly, electric actuator 11 is connected with PLC controller 5 electricity, PLC controller 5 is controlled pressure transmitter 7, flow switch 8 and solenoid valve 10. The air outlet of the air compressor 6 is communicated with a sludge pipeline 3 between the flow switch 8 and the electromagnetic valve 10 through an air pipe, and a compressed air interface 9 communicated with the air outlet of the air compressor 6 is arranged on the sludge pipeline 3; and the air compressor 6 is electrically connected with the PLC 5 and is controlled by the PLC 5. The PLC 5 is electrically connected with the sludge pump 4 and controls the switch of the sludge pump.
The specific working process is as follows: after the PLC controller 5 starts the sludge pump 4, the sludge pump 4 works, when the sludge pipeline 3 is smooth and free of blockage, the sludge fluid touches the flow switch 8, the flow switch 8 sends a signal to the PLC controller 5, the PLC controller 5 sends an opening signal to the electric actuator 11 of the electromagnetic valve 10, the electromagnetic valve 10 is opened, the sludge fluid is pumped from the sludge tank 1 to the sedimentation tank 2, and the system operates normally.
