Submerged arc furnace smelting ferrochromium pellet particle size measurement device and method

Abstract

The invention discloses a submerged arc furnace smelting ferrochromium pellet particle size measurement device and method. The device comprises a pelletizing disc, a feeding belt for conveying materials to the pelletizing disc, a scraper system for stirring materials in the pelletizing disc, and an atomize-spraying device used for adding water into the pelletizing disc, and further comprises a site local control box, an area array industrial intelligent camera, a high-brightness LED shadowless dome light source, a PLC station and an industrial Ethernet switch. A detection area of a round projection area is arranged on a chute between the discharging end of the pelletizing disc and a discharging baffle, a water distribution regulating valve is arranged on a water supply pipeline of the atomize-spraying device, the high-brightness LED shadowless dome light source directly irradiates the detection area, and the area array industrial intelligent camera is installed right in the middle of the top end of the high-brightness LED shadowless dome light source. By the adoption of the technical scheme, the opening degree of the pneumatic water distribution regulating valve is controlled, the mathematic relation of water distribution and pallet size is established through online debugging and real-time monitoring, and then automatic identification and control are realized.

Description

technical field [0001] The invention relates to submerged arc furnace smelting mechanical equipment, in particular to shaft furnace ferrochromium smelting pelletizing equipment, which realizes automatic identification of pellet particle size and controls the particle size detection device of submerged arc furnace smelting ferrochromium pellets within a specified range. and its detection method. Background technique [0002] National industrial policies have increasingly stringent requirements for energy conservation, environmental protection and product energy consumption.
