Movement before pushing mud cake and cathode filter press plate is continued to move along, until cathode filter press plate reaches maximum restraining position.Electricity
Osmosis system is closed, and ultrasonic unit works on, and ultrasonic transducer is glued together with cathode cellular board, can be realized altogether
Vibration makes mud cake be detached from cathode filter press plate, prevents from being bonded on filter cloth.Anode filter press plate starts to retract pressure under hydraulic cylinder effect
Inside cavity is filtered, mud cake is suspended, and realizes dump by cathode plate ultrasonic wave and gravity.First time filters pressing work terminates
Afterwards, control whole device carries out filters pressing work next time by this method, and all courses of work circuit sequentially, and can be realized fast
Fast efficient sludge dewatering work, not only can be with energy saving, but also dehydration efficiency can be improved.
In use, being dehydrated as follows:
Step 1: debugging is sequentially connected displacement sensor, controller, stepper motor, DC power control bus, simultaneously
The voltage readings for regulating DC power supply connect supersonic generator, ultrasonic transducer.All cathode filter press plates are in liquid
It previously moved under the induced effect of cylinder pressure, when limited step of the cathode filter press plate top to filters pressing cavity, was formed with filters pressing cavity
Interference fit, hydraulic cylinder fail.Meanwhile all anode filter press plates return to the feed inlet end of filters pressing cavity, are formed close
Seal work chamber.
Step 2: material feeding, by feed pump to all filters pressing cavity feed inlet material feedings, material feeding is completed to infuse for a period of time
Material, at this point, to be kept fixed position motionless for cathode filter press plate.
Step 3: filters pressing, constant voltage gradient electric osmose permeable system, ultrasonic unit power on start-up operation, and anode filter press plate exists
Hydraulic cylinder effect is lower to be moved forward, and the volume of working chamber starts zooming out, and carries out coupling filters pressing.In pressure-filtering process, anode filter press plate
Change in displacement then pass through displacement sensor and detected, and will test signal and send control panel to, control panel passes through stepping electricity
Machine drives DC power supply to adjust output voltage, at this point, the resistance value of sludge also changes constantly, adjusting output voltage be can be realized
The electro-osmosis of constant voltage gradient.Supersonic generator converts electrical energy into ultrasonic energy by ultrasonic transducer, to working chamber
The ultrasonic wave of indoor lasting transmitting certain frequency and power, to destroy the cenobium structure inside sludge, slough it includes water
Point.
Step 4: pressure maintaining, with the continuous increase of mechanical pressure, anode filter press plate moves forward, and reaches a level pressure
When power, pressure is not increasing, and the displacement of anode filter press plate gradually tends towards stability, and hydraulic cylinder continues pressure maintaining 2 minutes, constant voltage electric osmose
Permeable system and ultrasonic unit work on.
Step 5: dump, the hydraulic cylinder release of cathode filter press plate, at this point, anode filter press plate continues to move along promotion mud
It is mobile before cake and cathode filter press plate, until cathode filter press plate reaches maximum restraining position.Electric osmose permeable system is closed, ultrasonic wave
Device works on, and ultrasonic transducer is glued together with cathode cellular board, can be realized resonance, and mud cake is made to be detached from cathode pressure
Filter plate prevents from being bonded on filter cloth.Anode filter press plate starts to retract filters pressing inside cavity under hydraulic cylinder effect, and mud cake is hanged
Sky realizes dump by cathode plate ultrasonic wave and gravity, completes entire filters pressing work.
