Technical Field
The utility model relates to the field of blast furnace ironmaking production, in particular to a structure for continuously separating and recovering iron in blast furnace slag.
Background
At present, in the field of blast furnace iron-making production, the separation and recovery of metallic iron from blast furnace slag is an indispensable operation in the blast furnace production process, with the object of preventing iron in the blast furnace slag from burning out the slag pot and reducing the metal loss rate in blast furnace iron-making. However, in the conventional embodiment of separating and recovering iron from blast furnace slag, molten iron in the blast furnace slag is separated into a recovered iron pit, and the molten iron is lifted out of the recovered iron pit after solidification, so that the molten iron cannot be continuously separated and recovered after the recovered iron pit is filled, and online continuous operation is not available. The implementation method has long time consumption, high operation difficulty and larger danger coefficient. Because the liquid metal iron carried in the slag can not be continuously separated and recovered, the quality safety of the slag tank can not be ensured, and the metal loss rate can not be further reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a structure for continuously separating and recovering iron in blast furnace slag.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the structure for continuously separating and recovering iron in blast furnace slag comprises a blast furnace main iron runner and a branch iron runner, wherein a slag skimmer is arranged at the joint of the blast furnace main iron runner and the branch iron runner, a lower slag runner communicated with the side wall of the blast furnace main iron runner is arranged at the other end of the lower slag runner, an iron storage pit communicated with the lower slag runner is arranged at the other end of the lower slag runner, and a slag discharging channel communicated with the side wall of the iron storage pit is arranged at the side wall of the iron storage pit; the recovery ditch is arranged at the bottom of the iron storage pit and communicated with the iron storage pit, and the other end of the recovery ditch is communicated with the branch iron ditch; the horizontal position of the slag discharging channel is higher than that of the recycling channel.
Further, the method comprises the following steps: the recycling ditch is provided with a recycling iron pit which is a round pit.
Further, the method comprises the following steps: the bottom of the iron storage pit and the top of the branch iron groove are positioned at the same level, and the other end of the recovery groove is communicated with the top of the branch iron groove.
The utility model has the beneficial effects that: because the recovery ditch is arranged between the iron storage pit and the iron supporting ditch, the molten iron in the blast furnace slag can be continuously separated on line every tapping of the blast furnace; the recovery pit is arranged on the recovery channel, so that the situation of short tapping time of the blast furnace can be conveniently dealt with, and when less separated iron liquid exists, the iron liquid can be accumulated in the recovery pit, so that the phenomenon that the recovery channel is blocked by small iron flow is avoided, and the workload is reduced; the structure of the utility model can change the metal iron originally taken into account of the iron loss of the blast furnace into high-quality steel-making pig iron, increase the iron-making output of the blast furnace and optimize the production index.

Detailed Description
The utility model is further described with reference to the following figures and detailed description.
As shown in fig. 1 and 2, the structure for continuously separating and recovering iron from blast furnace slag according to the present invention comprises a main blast furnace iron runner 1 and a branch iron runner 2, wherein a skimmer is arranged at a joint of the main blast furnace iron runner 1 and the branch iron runner 2, molten iron smelted by a blast furnace flows into the branch iron runner 2 under the action of the skimmer, a lower slag runner 3 communicated with the side wall of the main blast furnace iron runner 1 is arranged on the side wall of the main blast furnace iron runner 1, blast furnace slag separated from the molten iron enters the lower slag runner 3, an iron storage pit 4 communicated with the other end of the lower slag runner 3 is arranged on the side wall of the iron storage pit 4, and a slag discharge channel 5 communicated with the iron storage pit 4 is arranged on the side wall of the iron storage pit; the recovery ditch 6 is arranged at the bottom of the iron storage pit 4 and communicated with the iron storage pit, and the other end of the recovery ditch 6 is communicated with the branch iron ditch 2; the slag channel 5 is located at a higher level than the recovery channel 6. The molten slag and the molten iron flowing into the iron storage pit 4 from the slag discharging groove 3 float on the molten iron due to different densities, and the molten iron flows into the recovery groove 6 from the bottom, so that the slag and iron shunting work is completed. Preferably, the lower slag runner 3 is arranged at the top of the iron storage pit 4, and the lower slag runner 3 and the slag outlet channel 5 are arranged at the same horizontal height, so that slag is convenient to discharge, the blockage is reduced, and the separation effect of iron in slag is improved.
