Problems solved by technology
But there are obvious defects: the equipment and facilities are complex and unreasonable, occupying a lot of land, large investment, and high operating costs; there are many fine-grained water slag in the slag flushing water, and the equipment is seriously worn. Slag accumulation, pipeline blockage, high equipment failure rate, low water slag flushing rate, large maintenance, high labor intensity for slag cleaning, affecting blast furnace production; large amount of supplementary water for slag flushing needs to be supplemented with industrial clean water, wasting water resources

This invention belongs to the molten slag treatment, especially relates to the blast furnace molten slag treating apparatus. The slag ditch connects with the granulating device and slag flume, the down part of the slag flume connects with the communicating pipe, the distributing trough that connects with the communicating pipe extends into the rotating drum filter, the belt device in the canister connects with the rotating belt device to form a finished articles warehouse; the down part of the rotating filter is arranged with the storage cabinet, laying-up basin, which are connected by the overflow on the pool wall, the dregs cleaning device is arranged on the storage cabinet the laying-up basin connects with the granulating device by the tube connector, valve and dregs cleaning pump. The device fault rate is low, the dregs punching out rate reaches up to more than 99%, which is propitious to the operation and steady production of the blast furnace. And the dreg cleaning water and the sewage is used in closed cycle, so it can save a lot of pure water.
Description
technical field [0001] The invention belongs to melting slag treatment, in particular to an ironmaking blast furnace slag treatment device. Background technique [0002] Blast furnace slag is an important by-product of ironmaking production, and the slag is rich in SiO 2 、Al 2 o 3 , CaO, MgO, etc., water slag granulated by water quenching is a high-quality raw material for cement production. The treatment of slag directly affects the production of blast furnace ironmaking. If the slag is well treated, the punching rate is high, the blast furnace runs smoothly, the production is stable, and the economic and environmental benefits are good. If the slag is not handled well, it will cause waste of resources, pollute the environment, and reduce the blast furnace wind. , Even forced to stop production. In the prior art, the processing device for the INBA method includes a brewing box, a water slag ditch, a water slag tank, a connecting pipe, a distributor, a drum filter, a bel...
