Resident measurement system for charge level of blast furnace

A resident measurement system for a charge level of a blast furnace, disposed at an opening of a lateral furnace wall at the top of the blast furnace, comprising:

• a chamber, combined with the furnace wall and covering the opening, wherein the chamber has a pivoting hole;
• a servo system, disposed in the chamber, and comprising a power device, a transmission element, and a movable bridge assembly, wherein the power device drives the transmission element, the movable bridge assembly is driven by the transmission element to perform a first motion in a first direction, the movable bridge assembly comprises a slide rod, a slide seat, and a connecting rod having a first end and a second end opposite to the first end, the slide seat rotates around the slide rod, and the first end of the connecting rod is connected to the slide seat;
• a distance measurement unit, having a pivot member across the pivoting hole and located within the opening, the distance measurement unit is connected to the second end of the connecting rod, and is driven by the connecting rod to perform a motion with the pivot as a movement center, so as to scan and measure the location and shape of the charge level, wherein the distance measurement unit further comprises a distance measurement device and a tubular element, and the tubular element passes through the pivot member and is connected to the distance measurement device;
• and
• a cooling-cleaning unit, connected to the distance measurement unit, for supplying a high-pressure gas, wherein the high-pressure gas is introduced into the blast furnace through the distance measurement unit.
