Filter tank operation under the normal filtration state usually; Detect in real time the pressure of the water to be filtered that flows through water inlet manifold through first pressure transducer, and convert first current signal of represent first force value to, flow through the pressure of water after the filtration of outfall sewer through the detection in real time of second pressure transducer; And convert second current signal of representing second pressure to; Through analog-digital commutator this first current signal and second current signal are converted to first digital signal of representing first pressure and represent second digital signal of second pressure and send arithmetic unit to, will represent first digital signal and second digital signal to subtract each other and produce pressure difference value through arithmetic unit, comparison means compares pressure difference value and preset threshold; When this pressure difference value during greater than preset threshold; Produce the back flush trigger pip and give controller, controller produces steering order according to the operational factor of trigger pip that receives and parameter setting apparatus transmission, and the method for operation of this moment is the back-flushing operation mode; Operational factor comprises air purge time and washing time; Digiverter converts the steering order of the digital signal that receives to simulating signal, and control needs water outlet total valve in the corresponding water inlet arm of the filter lattice of back flush, in the outfall sewer to close according to first voltage signal for second voltage signal of first voltage signal that this simulating signal comprises by-pass valve control and control blower fan, valve control device; Simultaneously through the work of second voltage signal control blower fan; At this moment, in the inlet manifold, feed pressed gas, pressed gas flows into the filter lattice from bottom to top through the air intake branch of need recoil filter wash lattice; And in the filter lattice, form impact air-flow; Impact the filter material layer in the filter lattice through impact air-flow, the filter lattice are carried out gas back-flushing, the material of being held back by filter material layer is come off from filter material layer.
When the air purge that reaches setting after the time; Gas back-flushing to these filter lattice finishes; Produce the steering order of water backwashing through controller; Convert the steering order of digital signal to simulating signal through digiverter once more, the flowing water Valve in the corresponding exit branch of the filter lattice of valve control device after control finishes through gas back-flushing according to first voltage signal is opened, and the air intake valve in the air intake branch is closed; Simultaneously, the power-equipment control device quits work according to second voltage signal control blower fan.
At this moment, water flows into outfall sewer as backwashing water after the filtration of other filter lattice, and backwashing water flows in these filter lattice through the exit branch of outfall sewer corresponding filter lattice after gas back-flushing finishes from bottom to top; And then back flush branch drain outflow of passing through these filter lattice should be filtered lattice; And flow out to the external world, thereby realize to be washed open by the material that filter material layer is held back to the water backwashing of these filter lattice through the back flush main drain; The material that to be separated behind the gas back-flushing is simultaneously taken away; Backwashing water flows out the filter lattice, through being removed by the material that filter material layer is held back after the above-mentioned back flush, to recover the filtering function of filter material layer.
After the washing time that reaches setting; Water backwashing to these filter lattice finishes; Corresponding inlet valve and the flowing water Valve of these filter lattice of steering order control through controller produces opened, and air intake valve and back flush water discharging valve are closed, and these filter lattice transfer the normal filtration state to.
After the back flush of completion to filter lattice, can repeat above-mentioned backwash process, to the steering order that other filter lattice carry out back flush, accomplish back flush successively, respectively filter lattice at last and recover normal filtration other filter lattice through the controller generation.
The technical scheme that the foregoing description provides produces back-flushing operation mode trigger pip through the pressure differential in filter lattice water inlet arm and the exit branch; This control system is further accomplished the course of work of back flush automatically when triggering makes the filter tank satisfy the back flush condition automatically through the trigger pip of back-flushing operation mode; Further reduced to realize the labour intensity of filter back washing, reduced the error that manually-operated brings through various valves of manually-operated and equipment.
