The present invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment 1：Full-automatic fluid removes the gred seperator, it include pedestal, shell, main motor, auxiliary motor, centrifugal chamber casing,
Clinker collecting box and removing device, removing device are located inside centrifugal chamber casing, include close to the scraper 9 of centrifugal chamber casing inner wall and suitable
The air-leg 10 that drives scraper centrifugal chamber in move horizontally affixed with scraper in shell is fitted over, is arranged in centrifugal chamber casing
There are cylindrical fluid nozzle and fluid outlet, cylindrical fluid nozzle to be in communication with the outside by pump, signal connects on the main motor
It is connected to PLC and the first frequency converter, signal is connected with strength of fluid sensor on the PLC, and pressure sensing is connected on the pump
Device, the pressure sensor signal are connected with the second frequency converter, and second frequency converter is connect with PLC signals, and the clinker is received
Header is built-in with the weighing sensor being connect with PLC signals.
The control method of full-automatic fluid slagging-off seperator, it includes the following steps：（1）, filtering control：PLC transfer tubes
Fluid is pumped by cylindrical fluid nozzle in centrifugal chamber casing by startup, and strength of fluid sensor detects the fluid in centrifugal chamber casing
Concentration, after fluid concentration is more than setting maximum concentration, PLC drives main motor to start, centrifugal chamber casing rotation, pressure sensor inspection
Survey the input oil liquid pressure of pump so that the input hydraulic pressure of pump is 0.3MPa；（2）, dehydration control：PLC control pumps shut down, and lead to
It is 3080 RPM to cross PLC and control the rotating speed of the first frequency converter；（3）, cleaning control：After fluid concentration reaches setting minimum concentration
PLC transfer tubes are started to work, and new oil, liquid are driven into centrifugal chamber casing, remove the internal remaining sludge not peeled off.
Embodiment 2：Difference lies in there are two the clinker collecting boxs, be spaced apart to connect in PLC signals with embodiment 1
On the conveyer belt connect, the two clinker collecting boxs can be referred to as tight preceding collecting box and next collecting box, one of them is located at gear
The underface of plate.
The control method of full-automatic fluid slagging-off seperator, difference lies in steps with embodiment 1（2）Dehydration control in
The rotating speed that the first frequency converter is controlled by PLC is 3100 RPM, in step（2）Dehydration control and step（3）Between cleaning control
It is more to strike off control：Weighing sensor is weighed to clinker collecting box and is compared with preset desired value in PLC, when more than mesh
PLC controls conveyer belt and the clinker collecting box equipped with sludge is delivered to other stations, the conveying of unloaded clinker collecting box after scale value
Below to centrifugal chamber casing.
Embodiment 3：The difference from example 2 is that there are three the clinker collecting boxs, it is spaced apart and connects in PLC signals
On the conveyer belt connect.
The control method of full-automatic fluid slagging-off seperator, the difference from example 2 is that step（2）Dehydration control in
The rotating speed that the first frequency converter is controlled by PLC is 3120 RPM.
Why the present invention controls the input hydraulic pressure of pump in 0.3MPa, is in order to avoid because strength of fluid or medium are former
Fuel transfer pressure is excessively high too low caused by, and pass through the study found that if hydraulic pressure less than 0.3 MPa can cause pump input fluid without
Method is sprayed in centrifugal rotor, if pressure is higher than 0.3MPa, the radial load of pump can be caused excessive, specific data see the table below：
Table 1
Research it has also been found that, under the premise of the input hydraulic pressure of pump is controlled in 0.3MPa, under identical particulate matter best dehydrating speed and
The relationship of electric current see the table below：
Table 2
It can be seen that dehydrating effect is bad when the rotating speed of the first frequency converter is less than 3080RPM, and it is slight sticky, when turning for the first frequency converter
Electric current is excessive when speed is higher than 3120RPM, influences the working life of frequency converter.
The present invention realizes the Automatic Control requirement for the seperator that removes the gred for fluid, stable, reliable, reduces manpower
Cost simultaneously reduces the consumption of the unnecessary operation in daily production.The dynamic monitoring to fluid is realized, and is being pinpointed the problems
Afterwards, maintenance policy information can be pushed in time, prevent problem worse, high degree of automation.
