It is turned over warm sludge and converts device 1 and detach；Crane, electric hoist etc. can be used in boom hoisting；
The clinker after fragmentation is turned over from warm sludge using the mode for pushing away slag rake, high pressure water or manual cleaning and is converted in device 1 clearly
Reason is fallen.
Embodiment：
The present invention, which is ploughed under in molten state blast furnace slag in the technique in smelting vessel, to be implemented, and is as follows：
Preparation stage：It 2 groups of steel chain ropes is laid in warm sludge turns over and convert in device, 4 steel chain ropes form 1 group, every steel chain rope
Diameter is about 5cm, a length of 10m, and the spacing of adjacent two steel chain ropes is 60cm, and every group of steel chain rope passes through the steel bar welding that spacing is 3m
Connection；Steel chain rope turns over to convert device slag inlet one end and by crotch button hang over warm sludge and turn in warm sludge converts device slag inlet breast board outer end,
Steel chain rope turns in warm sludge and converts device slag notch one end and be fixedly installed, and meets steel chain Suo Jun and be affixed on warm sludge and turn over and convert device bottom surface and put
It sets.
Turn over the slag stage：It is operated according to normal slag work flow of turning over, slag ladle and warm sludge turn over after converting device contraposition, tumble in tank
Molten blast furnace slag (temperature >=1250 DEG C) turns over the quantity of slag >=20t/ times, turns over slag number and is turned over depending on warm sludge and converts device floor space thickness of slag layer
Depending on, to extend the scarfing cinder period, the scarfing cinder operation frequency is reduced, it is to sentence to be turned over warm sludge and convert accumulated slag influence slag stream smooth outflow in device
According to progress scarfing cinder.
The disintegrating slag stage：When needing to carry out scarfing cinder operation, slag input end steel chain rope is hung over into the boom hoistings such as crane, electric hoist
On, dragging steel chain rope (2 groups are simultaneously) makes accumulated slag layer be shaken, and attrition crushing is fritter disintegrating slag and is turned over warm sludge and convert device and detach.
The scarfing cinder stage：It is turned over using high pressure water impact warm sludge and converts disintegrating slag block in device, 1 operative employee uses single high-pressure water pipe
Warm sludge can be turned in 10min and convert disintegrating slag block in device and clean out.Clinker, which with flow leaves warm sludge and turns over, to be converted device and falls into slag bucket
Middle draining, washing slag water enter the use of turbid circulating water system circulation, and the clinker after draining enters Solid state fermentation flow.
From the point of view of embodiment effect, warm sludge turns over the accumulated slag 2.4m for converting and having thickness about 10cm in device3, by pulling steel chain rope
Slag blanket is broken into fritter in 1min and is turned over warm sludge and converted device and be kept completely separate by group, and then 1 operative employee uses single high pressure
Disintegrating slag block is turned over to convert in device and be cleaned up completely by water pipe in 10min from warm sludge.
Present device small investment, characteristics of compact layout, it is easy to operate, be effectively improved operating environment, improve scarfing cinder operation effect
Rate can be applicable in the same industry.
