Laser charge level indicator charging mechanism of metal magnesium smelting high-pressure charger of 290mm-diameter reduction pot

Abstract

The invention relates to a laser charge level indicator charging mechanism of a metal magnesium smelting high-pressure charger of a 290mm-diameter reduction pot, which comprises a charging tube 1, a guide duct 2, a slag removal charging tube traction mechanism 3, a guide duct and charging tube sealing socket 4, a pulse valve gas inlet tube 5, a charging box 6, a pulse valve 7, a laser charge level indicator 8, a laser charge level indicator reflector 9 and a charging box pneumatic gate valve 10. The laser charge level indicator charging mechanism can accurately meter the burden pellet loadage according to the deformation degree of the 290mm-diameter reduction pot and different charging amounts of the reducing furnace, and can not have the phenomenon of manual secondary operation due to overloading or underloading; and the device has the advantages of simple structure, high automation degree and stable and reliable performance.

Description

technical field [0001] The invention relates to a laser level meter charging mechanism of a high-pressure slag-slagging charging machine for metal magnesium smelting with a reduction tank with a diameter of 290 mm. Background technique [0002] At present, the slag removal and charging machine in domestic and foreign magnesium metal smelters is only Roots blower airflow slag removal and charging integrated machine, and the degree of deformation of the reduction tank when the equipment is charged is different from the amount loaded in the reduction furnace, and the charge ball The measurement of the loading capacity of the regiment is inaccurate, and overload or insufficient loading often occurs, resulting in the phenomenon of manual secondary operations. Due to the limitation of the external dimensions of the laser level gauge itself, ordinary laser level gauges cannot be used for detection in the reduction tank with an inner wall diameter of 290mm.
