Description

Slag hole protection device of smelting furnace Technical Field The utility model relates to the technical field of metal smelting, in particular to a slag hole protection device of a smelting furnace. Background The smelting furnace refers to a furnace for melting iron ore, such as hematite (Fe 2O 3) or magnetite (Fe 3O 4), to make it pig iron (pigiron). Such vessels are of a refractory lined, highly cylindrical structure, filled from the top with a wash ore, coke and solvent (typically limestone). The conversion of iron oxide to metallic iron is a reduction process in which carbon monoxide and hydrogen are used as reducing agents. When the smelting furnace is used for slag discharge, high-temperature slag can splash around under the action of high pressure in the furnace, and certain potential safety hazards exist. However, in the prior art, the slag splashed during slag discharge is easy to cause damage to workers and equipment in a workshop, and in order to solve the defect that the prior art lacks a protection mechanism, the first protection cover, the second protection cover and other parts are arranged, so that the slag outlet body and the slag discharge groove are protected during slag discharge, the effect of avoiding slag splashing is achieved, and therefore a new scheme is required to be provided for solving the problem. Disclosure of utility model Against the above background, the prior art has the disadvantages and drawbacks of the protection mechanism. The utility model discloses a slag hole protection device of a smelting furnace, which comprises a slag hole body, wherein a slag hole is formed in one side of the slag hole body, two sides of the slag hole are respectively provided with a driving box, a first gear is rotationally connected in each driving box, a second gear is rotationally connected in each driving box, a driving plate is fixedly connected to each second gear, a first protective cover is arranged above the slag hole, a second protective cover is slidingly connected in the first protective cover, a first hydraulic rod is fixedly arranged on the first protective cover, and three sliding grooves are formed in the outer surface of the first protective cover. Further, a baffle is arranged above the slag discharge groove, and a top block is fixedly connected to the outer surface of the baffle. Further, the outer surface fixedly connected with support arm of kicking block, the other end of support arm rotates and is connected with the floorbar. Further, the other end of the supporting arm is fixedly connected with two transmission rods, and each transmission rod is rotationally connected with the bottom beam. Further, the middle section of the supporting arm is rotationally connected with two connecting rods, and the two connecting rods are symmetrically installed. Further, the upper surface of the bottom beam is fixedly provided with a second hydraulic rod, and the other end of the second hydraulic rod is fixedly connected with a driving block.
