Description

Spining disk method metallurgical slag treatment unit

Technical field

The utility model relates to a kind of treatment unit of metallurgical slag.

Background technology

In iron and steel enterprise, a large amount of metallurgical slag of annual generation is as blast furnace slag, converter slag, electric furnace slag etc.Except that containing small amounts of iron, steel constitution, main ingredient is CaO, MgO etc., is the good raw material of high-strength cement goods in these slags.For a long time, because of liquid slag temperature height, component mixes, and is difficult to handle, and steel mill mostly is poured over the slag field to it and piles up, and has not only wasted resource, but also has polluted environment.In the last few years, some steel mills had obtained some effects on the development and use metallurgical slag that pile up like a mountain, and through fragmentation, magnetic separation, sieve classification, the formation steel-making slag powder is returned sintering and made flux blast furnace slag in the factory that has; The factory that has makes fine ore with slag through ball milling, magnetic separation, as the adulterant of color concrete brick and cement of high index.Though these measures are turned waste into wealth, obtained good benefit, the problem of environmental pollution when failing to solve liquid slag and toppling over and take the problem that the slag field is done in a large amount of soils.

Baosteel is introduced Russian drum process slag treatment technology and patented technologies such as drum process metallurgical slag treatment unit that forms on this basis and inclined rotating drum method metallurgical slag treatment unit, realize suitability for industrialized production at Baosteel, can directly be processed into available cement raw material to the high-temperature liquid state slag, reduced environmental pollution, obtain good result of use, it is introduced that this technology of Baosteel maintains the leading position in the world.But this technology is by chute the high-temperature liquid state slag to be packed in the cylindrical shell that rotates, and through shrend, is ground in the rolling of the steel ball in cylindrical shell of the clinker after the shrend in cylindrical shell.Because cylindrical shell is horizontal positioned or tilted-putted, and in liquid slag must pack cylindrical shell into from simplified end, so chute also can only tilt, the slightly larger bits of the viscosity obstruction chute that easily bonds like this, and causing can't works better.And the quality that whole cylindrical shell rotates is big, the equipment complexity, and the application cost height, especially medium and small steel mill of iron and steel enterprise fails generally to promote always at home.

The utility model content

The technical problems to be solved in the utility model provides a kind of not susceptible to plugging liquid slag treatment facility, and not only cost is low, and use cost is also lower.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of spining disk method metallurgical slag treatment unit, and it comprises that a slag that is subjected to that is fixed on the support founds tube, is subjected to the top of the upright tube of slag to be provided with slag inlet, inside is provided with the shrend nozzle; A rotary disk is undertaken on the below that is subjected to the upright tube of slag, and steel ball is equipped with in trying to get to the heart of a matter to sieve shape of rotary disk in the rotary disk, and described rotary disk is connected with transmission mechanism by rotating bearing.

Different with existing drum process metallurgical slag treatment unit, the utility model has adopted a rotary disk that horizontally rotates that clinker is carried out ball milling, and be subjected to the upright tube of slag is fixed, slag inlet vertically downward so just can be set at the top that is subjected to the upright tube of slag, bonding can not take place and stop up in this slag inlet, therefore uses more safe and reliable.The utility model is simple in structure, the quality of rotating element is also less, is that cost or running cost are all lower therefore, and suitable medium and small especially steel mill uses.

Preferably, the described top of the upright tube of slag that is subjected to also is provided with blow-off line, and the water vapor that can better shrend be produced is discharged into outside the tube.

As improvement of the technical scheme, the described inside of the upright tube of slag that is subjected to also is provided with a division board, and slag inlet and shrend nozzle are kept apart.Division board will be divided into by the upright tube of slag and be subjected to slag district and shrend district, can avoid the high-temperature liquid state cinder ladle to wrap up in water and produce blast like this.

Preferably, be laid with the heat-resistant antifriction plate on the described inwall that is subjected to slag to found tube.

Preferably, trying to get to the heart of a matter of described rotary disk is made of the grid-like grid section, and the grid section top is connected with dismountable wear rib.

Preferably, the center of described rotary disk is provided with a fixed axle.

As the improvement of above-mentioned preferred version, described axle is a truncated cone-shaped, and the conical surface of round platform is provided with the strip flange, and this structure can be aggravated the relative movement between the steel ball, thereby improves mill slag efficient.

Preferably, the below of trying to get to the heart of a matter of described rotary disk is provided with the blanking chute, is provided with transfer roller below the blanking chute, can realize automated job continuously like this.
