On-line coal quality laser detection and analysis system

Abstract

The invention relates to an on-line coal quality laser detection and analysis system, which comprises an automatic coal-sampling unit, a continuous coal sample-tableting unit and a coal laser detection and analysis unit that are connected in sequence through cables, a conveyer belt and a manipulator; the conveyer belt connects the automatic coal-sampling unit with a pulverized coal sample bin of the continuous coal sample-tableting unit; the continuous coal sample-tableting unit comprises a sample-tableting disc, and a hydraulic head and a filling port are arranged on the top of the sample-tableting disc; a pulverized coal sample feed station and a filling station are arranged on the sample-tableting disc, and a pulverized coal tablet ejection station is arranged under the sample-tableting disc; the coal laser detection and analysis unit comprises a three-dimensional point location numerical control platform, a travelling unit is connected to the three-dimensional point location numerical control platform, and an optical focusing element, a pulsed laser and a laser detection and analysis instrument are arranged on the top of the three-dimensional point location numerical control platform. The on-line coal quality laser detection and analysis system can implement automatic sampling, automatic sample tableting and automatic laser detection and analysis in the process of coal transportation.

Description

technical field [0001] The invention belongs to the technical field of coal detection and relates to a laser online coal quality detection and analysis system. Background technique [0002] At present, coal is a fuel with a wide range of uses. It is used in a large amount in the coal power industry. The cost of coal combustion accounts for more than 70% of the operating cost of thermal power plants. The ash, calorific value, volatile matter, moisture and C, H, S and other elements in coal The content is the main indicator of coal analysis and analysis, and also the main indicator basis for coal quality acceptance settlement and guidance of boiler combustion. Traditional coal quality analysis mainly relies on traditional off-line manual sampling, sample preparation and laboratory analysis. The process is cumbersome and time-consuming, and coal information cannot be fed back in time, which brings many disadvantages: First, it takes several hours to know the analysis results, a...
