Full-coal-sample three-dimensional scanning off-line ash measuring device and method

Abstract

The invention discloses a full-coal-sample three-dimensional scanning off-line ash measuring device and method. The device comprises an upper synchronous double-rail sliding table, a lower synchronousdouble-rail sliding table, a side synchronous double-rail sliding table, a coal sample barrel, a radioactive source, a detector and a control assembly. The upper synchronous double-rail sliding tableis connected with an upper supporting plate; the lower synchronous double-rail sliding table is connected with a lower supporting plate; the side synchronous double-rail sliding table is connected with a radioactive source and a detector; the coal sample barrel is placed on the tray; the tray is connected with the transmission mechanism, the transmission mechanism is connected with the upper supporting plate or the lower supporting plate, the upper synchronous double-rail sliding table comprises an upper sliding table servo motor, the lower synchronous double-rail sliding table comprises a lower sliding table servo motor, the side synchronous double-rail sliding table comprises a side sliding table servo motor, the upper synchronous double-rail sliding table, the lower synchronous double-rail sliding table and the side synchronous double-rail sliding table are all fixed through supports, and the control assembly is electrically connected with the upper sliding table servo motor, the lower sliding table servo motor, the side sliding table servo motor and the transmission mechanism. By means of the technical scheme, three-dimensional scanning of all coal samples and centralized measurement of multiple coal samples are achieved, the number of times that personnel get close to a radioactive source is reduced, and the beneficial effects of being accurate in ash content measurementand high in efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of coal ash measurement, in particular to an off-line ash measurement device and method for three-dimensional scanning of a whole coal sample. Background technique [0002] Coal ash is the main basis for coal pricing, coal preparation, processing, production scheduling, and equipment operation. The real-time and accuracy of ash data directly affect the economic benefits and modern management level of the enterprise. Traditional methods of manual sampling, sample preparation, and manual ash analysis It is time-consuming and labor-intensive. It takes at least 2 hours to test an ash sample according to the national standard. The lag time of the obtained data is too long, which is of little significance for guiding the operation of the coal preparation process. Therefore, it is very important to measure coal ash content quickly and accurately with instruments. The online ash analyzer can only measure a single c...

Problems solved by technology

[0005] The present invention provides an off-line ash measurement device and method for three-dimensional scanning of the whole coal sample, which solves the problem of poor representativeness and large measurement error caused by the limited range of scanning coal samples of the existing off-line ash analyzer, and because only one coal sample can be measured at a time, if When measuring multiple coal samples, it is necessary to approach the offline ash analyzer multiple times to replace the coal samples, resulting in high labor intensity, increased chances of being exposed to radiation, and affecting the physical and mental health of the laboratory technicians.
