The course of work：
When being detached to aluminium slag, the aluminium slag generated in production is collected into agitated kettle 3, it is preferable to use cast steel agitated kettle first
3, it reuses fork truck and is placed into agitated kettle 3 on the platform 9 of aluminium slag separator of the invention, the temperature for being located at 2 tops of cover passes
Sensor 7 monitors the temperature of aluminium slag in agitated kettle 3, and temperature information is fed back to PLC controller 5.When temperature sensor 7 detects
Temperature when between 700-750 DEG C, PLC controller 5 control send out warning, add coal dust into agitated kettle 3 at this time, promote aluminium
Slag is warming up to 750-800 DEG C, and the aluminium slag of this temperature is more easily separated under the stirring action of agitating device（Aluminium fusing point is 660 DEG C）；
When temperature sensor 7 detects that aluminium slag temperature is less than 700 DEG C, PLC controller 5 sends out warning, is added at this time into agitated kettle 3
Slag-cleaning agent and coal dust, make aluminium slag fully burn, and temperature rises to 750-800 DEG C, are convenient for the separation of aluminium slag；When temperature sensor 7 is examined
It is excessively high to measure aluminium slag temperature（Higher than 800 DEG C）When, PLC controller 5 sends out warning, needs that low temperature is added into agitated kettle 3 at this time
Aluminium slag, so that the aluminium slag in agitated kettle 3 is cooled down, the final temperature that adjusts is between 750-800 DEG C.Scarfing cinder is added into agitated kettle 3
After agent and/or coal dust, PLC controller 5 controls 4 driving hydraulic cylinder 13 of hydraulic station, makes 15 downward retracting motion of telescopic rod, then makes
The agitating device being connected with connecting plate 14 moves downward, and moves closer to agitated kettle 3.Elevating mechanism is equipped with position-limit mechanism, including limit
Position plate 43 and limiter 44, limiting plate 43 are fixed in one end of connecting plate 14, and limiter 44 is equipped with upper and lower two, is arranged in cover 2
Side upper and positioned at hydraulic cylinder 13, limiter 44 are equipped with the sensor being connected with PLC controller 5.When the stirring palm 20 enters
When in agitated kettle 3, the limiting plate 43 on connecting plate 14 touches following limiter 44, and the sensor of limiter 44 is anti-by signal
PLC controller of feeding 5, PLC controller 5 control the movement that hydraulic station 4 stops hydraulic cylinder 13, under so that telescopic rod 15 is stopped
Drop.Then, motor 17 is opened in the control of PLC controller 5, drives speed reducer 18 to rotate, 19 band of agitating shaft being connected with speed reducer 18
Aluminium slag in 20 pairs of agitated kettles 3 of the dynamic stirring palm is stirred.Under the stirring action of the stirring palm 20, aluminium slag and slag-cleaning agent and/or
Coal dust is sufficiently mixed contact so that aluminium slag is brought rapidly up and is maintained between 750-800 DEG C, realizes point of the aluminum melt with slag body
From aluminum melt flows to 3 bottom of agitated kettle, while slag-cleaning agent has absorption and dissolution to slag body, can reduce aluminum melt and slag body
Between binding force, efficiently separate aluminium and slag；After slag-cleaning agent is added, a large amount of bubble can be generated in aluminum melt, can also risen
To the effect of stirring melt, and slag body can be stirred to the surface of aluminum melt, aluminium slag separation is facilitated to carry out fishing slag after the completion.It is propping up
Place the molten aluminum collector 6 for collecting molten aluminum on the parcel shelf 11 of the lower section of frame 1, the aluminum melt detached with slag body is from 3 bottom of agitated kettle
Molten aluminum outlet flow out in molten aluminum collector 6, to complete the separation of aluminium slag.After the completion of aluminium slag separation, PLC controller 5 is controlled
System closes motor 17, and speed reducer 18 is decelerated to agitating shaft 19 and the stirring palm 20 stops operating, and PLC controller 5 controls hydraulic station 4 and opens
Dynamic, 4 driving hydraulic cylinder 13 of hydraulic station makes telescopic rod 15 rise, and drives the stirring palm 20 to rise from agitated kettle 3, when on connecting plate 14
Limiting plate 43 when encountering limiter 44 above, signal is fed back to PLC controller 5, PLC controls by the sensor of limiter 44
Device 5 controls the movement that hydraulic station 4 stops hydraulic cylinder 13, to make agitating device rise to the top of agitated kettle 3.Then, PLC is controlled
The control valve 8.1 of water pipe 8 is opened in the control of device 5 processed, is sprayed water into agitated kettle 3, and agitated kettle 3 is made to cool down.The present invention by machinery from
Dynamic stirring, realizes the automation of aluminium slag separation, reduces the labor intensity of worker, improves stirring efficiency and aluminium slag separation effect
Rate, and mixing effect is more uniform.
Embodiment 2
As shown in Fig. 2, the present embodiment and embodiment 1 difference lies in：Further include electromagnetic heater 21, power supply 22 and temperature control
Device 23；The electromagnetic heater 21 is connected with the power supply 22 and temperature controller 23 respectively；The electromagnetic heater 21 is equipped with
Electromagnetic heating coil 24；3 outer surface of the agitated kettle is enclosed with heat-preservation cotton 25, and 25 thickness of the heat-preservation cotton is 20-25mm；The guarantor
Warm cotton 25 is wrapped with high temperature cloth 26.Wherein, the 21 model Hac 10/220 of electromagnetic heater of the present embodiment, temperature controller
23 model CN132-12V.
Since temperature can reduce aluminium slag in collection and transportational process, sometimes when overlong time, aluminium slag is completely cooling,
As aluminium with the form of slag is at this time, it can not be detached.The fusing point of aluminium is 660 DEG C or so, to realize the separation of aluminium and slag,
Temperature must be raised to the fusing point of aluminium or more, aluminium is made to become aluminum melt, exported in liquid form from the molten aluminum of 3 bottom end of agitated kettle
Outflow, the continuation of slag body is stayed in solid forms in agitated kettle 3, to realize the separation of aluminium and slag.When what is be collected into agitated kettle 3
When aluminium slag temperature is too low, only between addition slag-cleaning agent and/or coal dust make aluminium slag be warming up to 750-800 DEG C, it can cause to detach
Journey takes too long, and separative efficiency is low, and can also consume excessive slag-cleaning agent and coal dust, and cost is higher.Therefore, in agitated kettle 3
Outer surface superscribe the heat-preservation cotton 25 that thickness is 20-25mm, then enclose a floor height stupe 26, aluminium slag be collected into cast steel stirring
It in pot 3, is wrapped in high temperature cloth 26, leads to by forklift transport to platform 9, then by the electromagnetic heating coil 24 of electromagnetic heater 21
It crosses after agitated kettle 3 is placed on platform 9 by fork truck, slag-cleaning agent and/or coal dust is added into agitated kettle 3.Pass through the side of electromagnetic heating
Formula preheats the aluminium slag in agitated kettle 3, passes through the temperature of the control preheating of temperature controller 23（Such as 600 DEG C）.Preheating is completed
Afterwards, power supply 22 is closed, electromagnetic heating coil 24 stops heating.At this point, again by agitating device to the aluminium slag in agitated kettle 3, scarfing cinder
Agent and/or coal dust are stirred heating separation, accelerate heating rate, substantially reduce the heating-up time, improve aluminium slag separation
Efficiency.
