The intake of internal slurry.
Load in the case where the slurry entered in separating mechanism increases, on outer drum 210 and screw feeder 220
Material can all increase, then operating current and the second motor 320 that first motor 310 drives outer drum 210 to rotate drive spiral
The operating current that pusher 220 rotates will necessarily become larger with increasing for material, and user can pass through first motor 310
Or second motor 320 operating current judge separating mechanism delivered inside slurry amount.
Operating current judgment step: S300 it is default to judge whether the operating current of first motor 310 is greater than or equal to first
Threshold value, or judge whether the operating current of the second motor 320 is greater than or equal to the second preset threshold；Preferably, in " work electricity
Stream judgment step " further includes that motor working current presets step: maximum operating currenbt value X is arranged for first motor 310, is second
Maximum operating currenbt value Y is arranged in motor 320.That is the reality by judging first motor 310 and the second motor 320 is needed
The size relation of operating current and default maximum operating currenbt value, to judge whether the interior slurry of separating mechanism reaches separation of solid and liquid
The maximum intake of equipment safety work.
S400 feeds rate-determining steps: when judge the operating current of first motor 310 more than or equal to the first preset threshold,
Or second motor 320 operating current be greater than or equal to the second preset threshold when, then stop feeding.Entering in separating mechanism
Slurry gradually increase in the case where, the load inventory on outer drum 210 and screw feeder 220 can all increase, then
The work that the operating current and the second motor 320 driving screw feeder 220 that one motor 310 drives outer drum 210 to rotate rotate
Electric current will necessarily become larger with increasing for material.Control unit 600 is greater than or waits in the operating current for judging first motor 310
When the operating current of maximum operating currenbt value X or the second motor 320 is greater than or equal to maximum operating currenbt value Y, illustrate point
It is excessive from in-house slurry, it continues to be fed into slurry and be easy to cause motor even separating mechanism damage, at this time control unit 600
It controls feed pump 420 and closes and stop charging.
In further embodiment, when judge the operating current of first motor 310 less than the first preset threshold, and the second electricity
The operating current of machine 320 then starts charging or keeps charging less than the second preset threshold.Control unit is judging first motor
310 operating current is greater than or equal to maximum operating currenbt value X, and the operating current of the second motor 320 is greater than or equal to most
When big working current value Y, illustrate that the slurry inside separating mechanism is no more than maximum intake, two motors may continue to normal work
Make.If feed pump 420 are at and start into state at this time, control unit 600 does not do order, and feed pump 420 continues work
Make；If feed pump 420 is in close state, starts feed pump 420 and carry out feeding work.Using such working method, separation
Slurry can be passed through in mechanism in time, guarantees equipment for separating liquid from solid continuous work, greatly improves working efficiency.
In preferred embodiment, the control method includes further include:
Electric machine speed regulation step: the revolving speed of control adjustment first motor 310 and/or the second motor 320.Due to be passed through into
The slurry that row is separated by solid-liquid separation is different, and rotational speed difference required for outer drum 210 and screw feeder 220 is also not to the utmost in separating mechanism
It is identical, control unit 600 is first passed through before carrying out pulp separation work controls first motor 310 and/or the second motor 320
Rotational speed regulation is carried out, to obtain different rotational speed differences, to adapt to the separation of solid and liquid work of different slurries.
In preferred embodiment, the control method further include:
Working oil temperature detecting step: the working oil temperature of lubricating oil is detected；
Working oil temperature judgment step: judge whether the oil temperature of lubricating oil is greater than or equal to preset threshold；
Motor start and stop step: when the oil temperature of lubricating oil is greater than or equal to preset threshold, first motor 310 and the are closed
Two motors 320.The device working condition being able to reflect out by the oil temperature of 250 lubricating oil of rolling bearing, if oil temperature is normally said
Bright device is working properly to work on, if high oil temperature, illustrate to work at least rolling bearing 250 abnormal, Gu
Liquid separating apparatus may break down, and work on and be very easy to cause the damage of rolling bearing 250 or even whole device, at this time
It needs to carry out shutdown inspection.Therefore, in this mode, need again to be arranged in control unit 600 the maximum functional oil temperature of lubricating oil,
The oil temperature of lubricating oil is detected by the temperature detecting unit 740 being arranged in lubricating system, and feeds back to control unit 600, works as control
When unit 600 processed judges that the actual working oil temperature of lubricating oil is greater than or equal to maximum rated working oil temperature, then first motor is controlled
310 and second motor 320 open closing, equipment for separating liquid from solid stops working, to play a protective role.
