Device for detecting high-temperature metal liquid level in flame and smoke environments

The invention discloses a device for detecting a high-temperature metal liquid level in flame and smoke environments, and the device comprises a first laser distance measuring sensor which is provided with a first cleaning channel below and is used for detecting the height of a carbon block, a second laser distance measuring sensor provided with a second cleaning channel arranged below and is used for detecting the liquid level height when the liquid metal is injected into a carbon bowl, and a laser distance measuring sensor with a third cleaning channel arranged below and used for detecting the liquid level height when the liquid metal in the carbon bowl is stable; and the first cleaning channel, the second cleaning channel and the third cleaning channel are connected with fans. The heights of the front stage, the middle stage and the rear stage of metal liquid injected into the carbon bowl can be detected, interference of flames and smoke dust is eliminated, the accuracy of detection data is guaranteed, man
