Blast furnace material level measuring device

Abstract

The invention relates to the technical field of blast furnace detection, in particular to a blast furnace material level measuring device, which comprises a fastening unit, a support frame, a fixing unit, a measuring unit and a transmission unit, wherein the fastening unit and the fixing unit are arranged on the same straight line, the two ends of the support frame are respectively connected with the fastening unit and the fixing unit, one end of the measuring unit is movably connected with the support frame, the transmission unit passes through the fixing unit to be screwed with the fastening unit, and the transmission unit is also fixedly connected with the measuring unit. The blast furnace material level measuring device provided by the invention has the advantages that the structure is simple, and the angle does not need to be measured, so the introduced error factors are few, and the material level height and the material level descending speed obtained through calculation are very precise and reliable.

Description

Technical field [0001] The invention relates to the technical field of blast furnace detection, in particular to a blast furnace material level detection device. Background technique [0002] The methods of measuring the height and shape of the object surface on site mainly include manual measurement, laser measurement and radar measurement. These methods can easily measure simple displacements (such as vertical height, distance, etc.) or positions that can be directly contacted. It is difficult to measure to or dangerous parts. Although some of the above-mentioned problems can be solved by adjusting the angle of the measurement tool, the accuracy of the measurement result is greatly reduced due to the accuracy of the angle measurement. At present, the measurement of blast furnace material level is mainly heavy hammer material ruler and radar probe, etc., which can conveniently and continuously measure the vertical height of a certain point on the blast furnace material surface ...

AI Technical Summary

Problems solved by technology

Due to the limited installation position of the furnace roof, multiple radars cannot be installed vertically on a straight line. As the charge level of the blast furnace falls, the measurement results cannot be on a straight line, which cannot well represent the shape of the charge surface of the blast furnace and the falling speed of the charge.

In addition, some measuring devices also use the motor to drive the worm reducer for automatic measurement. The height of the measurement point is calculated by determining the measurement angle through the angle machine amplification method. Since the number of motor revolutions is difficult to control and determine, the measurement result has a large error
