Tracking type coal bunker material level measurement device

Abstract

The invention relates to a tracking type coal bunker material level measurement device and belongs to the technical field of automatic detection and measurement. The tracking type coal bunker material level measurement device is characterized in that the continuous coal bunker material level automatic measurement device consists of a probe 1, a transmission system and a measurement system; the probe 1 is a metal cone hollow body; the whole metal cone hollow body is filled with epoxy resin; an upper limit sensor 2 and a lower limit sensor 3 are mounted inside the metal cone hollow body; the upper limit sensor 2 and the lower limit sensor 3 are reflection infrared photoelectric proximity switches integrating transmitters with receivers; when a material level in a coal bunker is changed, switching value signals output by the upper limit sensor 2 and the lower limit sensor 3 are transmitted to a material level intelligent meter 11 through an electric cable 4; the transmission system consists of a steel wire rope 5, a pulley 6, a motor 7, a speed reducer 8 and a steel wire rope roller 9; and the measurement system consists of a coding sensor 10 and the material level intelligent meter 11. The tracking type coal bunker material level measurement device has the advantages of high measurement precision, long service life and continuous dynamic tracking measurement and is mainly used for measuring the material level of the coal bunker of a coal mine, a coal washery and a power station.

Description

technical field [0001] The invention relates to a tracking type coal bunker material level measuring device, which belongs to the technical field of automatic detection and measurement. It is a continuous and uninterrupted coal bunker material level automatic measuring device, which overcomes the material level measurement of the solid material repose angle in the existing measuring means. The disadvantage of accuracy is relatively large. It is mainly used in coal mines, coal washing plants and power plants to measure the material level of coal bunkers. Background technique [0002] Coal bunkers are the main facilities for temporary storage of raw coal in large coal mines, power plants and coal washing plants. In most cases, they are upright cylinders cast in concrete, usually in groups of two, four or eight, with a diameter of more than ten meters. , 40 to 50 meters high, and the volume of each coal bunker is about 5,000 cubic meters. The material level of the coal bunker...

Problems solved by technology

[0007] The present invention is a tracking type coal bunker material level measuring device, whose purpose is to overcome the disadvantage that the angle of repose of solid material has a relatively large influence on the accuracy of material level measurement in the existing measuring means, and to solve the measurement interval of the heavy hammer type material level measuring device. The time is long and the weight is easy to be buried, so an automatic tracking continuous dynamic measuring device is mainly used in the coal mine, coal washing plant and power plant coal bunker level measurement.
