During machine, only need to adjust and just set back pressure under fixed main shaft electric machine frequency, according to output dirt
Mud moisture content selects suitable corresponding back pressure, and eliminating conventional folded spiral shell machine needs same during debugging
Time adjust electric machine frequency and mud extraction gap, and the uncontrollable problem of back pressure, at the beginning of substantially reduce the number
Debugging time beginning and loaded down with trivial details step；And can have repeatability with fixing quantity processing parameter,
And the mud of different moisture content can corresponding different back pressure and different electric currents, so debug
Simpler and specification.
And there is the difficult point that cannot regulate processing speed in running in the most conventional folded spiral shell machine,
Owing to back pressure is uncontrollable, and back pressure can change along with the impact of processing speed, improves main
Although but spindle motor frequency can improve processing speed be added significantly to motor load and again can simultaneously
Affecting back pressure, moisture content of the cake can change；Although and reducing spindle motor frequency and reduce process
Speed still greatly reduces back pressure, and moisture content of the cake significantly raises；And for this difficulty at present
Point, the structure of the present invention completely solves this problem, even if running changes processing speed,
As long as and adjust or keep the current value of electromagnet 6 within the specific limits, back pressure can be remained
Power is constant, and moisture percentage in sewage sludge is unaffected.So for mud of different nature, different containing wet
Amount and production capacity, by setting back pressure, fully automated control.
