Description
Technical field
The utility model relates to hot vexed slag ladle, relates in particular to a kind of steel slag hot disintegrating slag ladle that has whipping appts.
Background technology
Along with increasing rapidly of China's crude steel output, the total amount of slag is also constantly increasing thereupon, and the total amount of China's bessemer furnace slag in 2010 reaches more than 9,000 ten thousand tons.In the past, slag is regarded as waste always.Through years of researches and practice, people have developed the method for multiple processing slag, and slag is turned waste into wealth, and have not only reclaimed ample resources, and have reduced the harm that slag causes environment.Domestic bessemer furnace slag treatment process is more, mainly contains hot vexed method, wind crush method, water quenching, hot application method, tray method and drum process.From the popularity of using; The vexed method of heat is more and more general in the application of each big section steel works; Become main development trend gradually, the steel mill that the vexed method of domestic employing heat is handled slag mainly contains Baosteel, Ji steel, Hunan steel, splendid steel, goes up steel five factories, Nanjing steel mill, the long smelting in Shanxi steel mill or the like.
The vexed method of heat is that bessemer furnace slag is poured in the hot disintegrating device, covers the hot disintegrating device lid, and in hot disintegrating device, sprays water.Complex physico-chemical takes place in the saturation steam of water generates and the free calcium oxide in the slag (f-CaO) and free magnesium (f-MgO), makes the slag cooling, and cracking takes place simultaneously, final efflorescence.Technological development and come two kinds of technologies of vexed method of pot type heat and the hot vexed method of pond formula are arranged thus.The shortcoming of the vexed method of existing pot type heat is: 1, occur slag surface crust and slag caking in the process of hot vexed slag easily.In the vexed slag process of heat, crust rapidly because of meeting water in the molten steel slag surface, hinders water and react with inner hot steel slag, thereby can't realize further cracking of slag and efflorescence; In addition, certain a part of slag has not also just solidified cooling with the water reaction in the slag, forms clinker; The hardness of clinker is higher, can't be broken, and (most steel mills carry out the clinker that diameter reaches 0.5 ~ 1m all occurring in the hot vexed process to slag can not to carry out magnetic separation; Adopt the professional crusher could be broken), therefore, in the vexed slag process of heat, need open cover and slag is shoveled dig operation; At present, generally adopt excavator that skull and clinker are smashed to pieces, impel steel slag hot disintegrating abundant; Often to be equipped with several excavators and the cost of doing like this is the slag field, the loss fund of annual excavator accessory reach millions of more than.2, need open cover owing to smash clinker to pieces, will influence hot vexed effect, cause calorific loss, the hot vexed treatment time is long, and efficient is low.
The utility model content
The technical problem that the utility model will solve is the deficiency that overcomes prior art, provides a kind of simple in structure, can guarantee that water and hot steel slag fully react, and impels steel slag cracking, efflorescence complete, the steel slag hot disintegrating slag ladle that has whipping appts that hot vexed efficient is high.

Said mixer drive comprises motor and wheel box, and the output terminal of said motor links to each other with the input terminus of said wheel box, and the output terminal of said wheel box links to each other with said coupling lever.
Said mixer drive also comprises the lifting drive that is used to drive the coupling lever up-down.
Said slag ladle covers pad and is provided with thermal baffle.
Said slag ladle covers and is provided with the gas exhaust duct that communicates with the slag ladle body interior.
Said paddle is sheet paddle or rod-type paddle or vane type paddle.
Compared with prior art, the advantage of the utility model is:
The steel slag hot disintegrating slag ladle that has whipping appts of the utility model; Cooperation through mixer drive, paddle and water jet standpipe; In the vexed process of heat, can realize stirring slag, broken skull and clinker while spraying water; Guarantee that water and hot steel slag fully react, impel steel slag cracking, efflorescence complete; Also can keep simultaneously the relatively stable of the interior high-temperature steam pressure of slag ladle, realize that vapor pressure is controlled, avoid calorific loss, guarantee hot vexed effect, reduce the hot vexed time length, raise the efficiency.
