In the blast furnace smelting tapping process, after molten iron in a blast furnace is opened by a tapping machine, the molten iron flows into a main runner from the tap hole, then is subjected to iron-slag separation by a skimmer, and enters a swing spout through an iron runner and then enters an iron-receiving torpedo ladle. The forward cutting and rotation of the tapping machine during tapping are both driven by the feeding device. The feeding speed and pressure can be changed along with the change of the depth of the taphole, the deeper the taphole, the higher the corresponding feeding speed and pressure requirements, and particularly when the tapping machine is influenced by the furnace condition, the higher the feeding requirements of the tapping machine are. With the improvement of the productivity, the feeding device of the tapping machine used at present is a heavy single drive, as shown in fig. 2, the drive of the tapping machine is difficult to meet the field requirement, faults such as weak feeding, feed blockage, oil leakage of a drive motor oil seal, damage of the drive motor and the like often occur during tapping, and finally the tapping is difficult to open and can only be manually tapped, so that the normal production is influenced.
Along with the increase of daily productivity of blast furnace molten iron, the driving capability of the tapping machine for feeding is insufficient, so that the tapping machine is difficult to tap a taphole, the tapping time is seriously influenced, and the normal production and the smooth running of the blast furnace are seriously disturbed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is exactly in order to solve the not enough problem of current blast furnace tapping machine driving force, provides a light-duty dual drive feeding device of blast furnace tapping machine, will feed heavy single drive optimization and be light-duty dual drive device, eliminates because of bearing seal oil leak, the inside spare part fragile of motor that the feeding device trouble brought, changes phenomenons such as frequent, reduces cost of maintenance, maintains normal safety in production.
In order to realize the purpose, the utility model adopts the following technical scheme:
