Description
Technical field
The utility model relates to a kind of pressure and flux controllable INBA Handling Blast Furnace Granulated Slag device, belong at blast-furnace slag
Manage equipment technical field.
Background technique
INBA method is a kind of blast-furnace slag processing method, and this method will be input to rotary drum by Pulp pump after slag water quenching
It realizes dehydration, finally obtains grain slag.INBA method flush slag is the patented technology of Bao Er Water Company, compact arrangement of equipment, land occupation
Area is small, and whole flow process automated machine may be implemented.Grain slag is high-quality, washing slag water closed cycle, and aqueous suspension is few.Pump and
The abrasion of pipeline is small, no explosion danger, and degree of safety is high, and when iron content degree is high in slag, which can also carry out safely the granulation of clinker.
The basic technology of INBA method Slag treatment is: the slag that blast furnace generates enters granulation tower through slag runner, and washing slag water is by slag
It smashes rapidly, forms graininess grain slag, slag, aqueous mixtures enter dewatering drum, and grain slag is evenly distributed by the distributor in rotary drum
To baffle-box, slag sand is placed into belt working face by mentioning slag net, then is transported by belt.It mentions slag net and slag sand is placed into the same of belt
When, water enters clear water reserviors by overflow launder, is delivered to water cooling pond through heat-exchanger pump, is recycled.Most enterprises are using INBA

Imbalance will result in one side pond and drain another pond spilling water, can not normally produce.(3) it is automatically adjusted according to the quantity of slag, torque
Rotary drum revolving speed, while guaranteeing that spilling water is not difficult to realize rotary drum.Under certain quantity of slag or torque, rotary drum revolving speed is slow, and slag, which is deposited in, to be turned
In drum, rotary drum, which is killed, to be rotated；Revolving speed is fast, and water filtering is not clean, and band water band slag is more on belt, wears roller, carrying roller, belt
Etc. equipment.(4) belt conveyer head scavenging conduit can not effectively blow off dry slag on belt, and corrosion is more serious, and frequently, replacement is blown for replacement
It sweeps pipe to have to stop belt, influences normal transport grain slag, also increase labor intensity.(5) leakproofness of butterfly valve is poor, in valve
When door is closed, water is flowed out from the gap of butterfly valve, and slag sand wash is at valve, and for a long time, slag sand is hardened in pipeline lower part, causes
Valve switch is difficult, and slag blanket constantly thickens, and blocks pipeline.
