Description
Technical field
The present invention relates generally to blast furnace smelting iron technical field, is specifically related to a kind of blast furnace slag iron runner molding sand cyclic utilization system.
Background technology
Nowadays the technological process extract from iron-bearing mineral by metallic iron exactly smelted by the cast iron in foundry industry, mainly contain blast furnace process, direct-reduction process, smelting reduction method, plasma method, blast furnace smelting process utilizes taphole drilling machine, clay gun, the specific equipments such as stopper and instrument, slag is opened respectively by specific time, iron mouth, slagging, molten iron, and flow into slag bath respectively through slag iron runner, in hot metal ladle, slag iron is shutoff slag after rolling, iron mouth, to ensure carrying out continuously of blast fumance, slag needs the groove formed by sand to flow in slag bath, general all needs carries out repairing and changing sand with spade by workman, should not again use continuously by the sand temperature height impurity that constantly uses is many, and labor strength is large, work situation is severe, will develop and promote recycle zero-discharge technology and typical module according to the future plan of China, the regeneration therefore realizing cast waste sand is a urgent problem simultaneously.
Summary of the invention
Problem existing during slag iron runner molding sand in prior art is utilized, a kind of blast furnace slag iron runner molding sand cyclic utilization system provided by the invention, can realize the recycle of casting model powder, save manpower consumption, improve Working environment, avoid the waste of resource, more effectively utilize resource.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of blast furnace slag iron runner molding sand cyclic utilization system, mainly comprise blast furnace, bin, sandbox, cooled filter tower, described blast furnace is provided with outlet and connects sandbox, by sandbox, slag iron runner is set, be used for guiding molten iron, slag flows into hot metal ladle, slag bath, sandbox two ends are provided with steel structure support, bin is connected by wheel chain, bin can be controlled move up and down, described sandbox one end is provided with old sand conduit, old sand can be transported by conveying belt, the end of old sand conduit is connected with cooled filter tower, old sand can be carried out cooling process by cooled filter tower, finally old sand is filtered, the scum etc. of mixing in sand is separated, the intervention avoiding some impurity affects the quality of molten iron, sand after filtration is transported by transport pipe, described transport pipe is connected with bin.
Preferably, bottom described steel structure support, be provided with slide rail, steel structure support tangential movement can be made by slide rail, during molten iron discharging, bin can be controlled and move away high-temperature area, doing so avoids the too high equipment that makes of temperature and fire-cureed.
Preferably, described bin lower end is provided with the mouth that shakes out, and by shaking out, the sand in bin is deposited in sandbox by mouth uniformly, avoids the environmental pollution of dust.
Beneficial effect of the present invention shows: the quality substantially increasing cast iron, decreases being mixed into of impurity, decreases the waste of resource, achieve the recycle of casting model powder, greatly reduce the pollution of dust, improve work situation and the workload of workman, achieve the more good utilisation of resource.
