Getting-through device of smelting furnace ventilation opening and getting-through method

Abstract

The invention belongs to the field of getting through of a smelting furnace ventilation opening, and particularly relates to a getting-through device of a smelting furnace ventilation opening and a getting-through method. The getting-through device comprises a motion bearing support, a first guide rail, an extension framework assembly, and a top layer getting-through mechanism; the extension framework assembly comprises n layers of extension frameworks, wherein n is larger than or equal to 0. The extension framework comprises an extension plate and a second guide rail, the extension plate slides along the guide rail below the extension plate, and the top layer getting-through mechanism comprises a top layer mounting plate, a third guide rail, a steel chisel pre-feeding air cylinder, a first sliding block, an energy storage impact and a steel chisel guide rod; a first motor is arranged on the motion bearing support, an output shaft of the first motor is fixedly connected with one end ofa first connecting rod, the other end of the first connecting rod is in pin connection with one end of a second connecting rod, and the other end of the second connecting rod is hinged to the top layer mounting plate. After the device retreats from the ventilation opening, the first motor, the steel chisel pre-feeding air cylinder and the energy storage impact air cylinder work at the same time,retreating is achieved within the shortest period of time, and molten lead outflow can be prevented.

Description

technical field [0001] The invention belongs to the technical field of smelting, and in particular relates to a device and a method for opening a vent of a smelting furnace. Background technique [0002] Traditional lead smelting is produced by sintering-blast furnace process, which can no longer meet the increasingly stringent environmental protection regulations and the requirements of energy saving and consumption reduction. At present, most lead smelting adopts a new process in which oxidation furnace, reduction furnace and fuming furnace are connected. During the work of the reduction furnace, manual or automatic mechanical equipment is required to quickly open the crystalline impurities in the vent to ensure that the oxygen-enriched air can enter the oxidation furnace or reduction furnace smoothly. Charge and fuel are fed in batches from the charging port on the upper part of the furnace, and oxygen-enriched air is blown in from the tuyeres on both sides of the lower p...
