AI Technical Summary

Technical Problem

The existing online ash detection method for coal preparation is unevenly distributed during the transportation process, resulting in the measurement value often lower than the test value, affecting the detection accuracy.

Method used

A coal preparation online ash detection sensing device is designed, including a feeding mechanism and a vibration assembly. The feeding mechanism drives the feeding hopper to the vibrating screen through a pneumatic cylinder. The vibrating assembly uses the cooperation of the vibrating screen and the discharge rack to ensure the distribution of coal particles evenly, thereby improving the detection accuracy.

Benefits of technology

Through uniformly distributed coal particles, the accuracy of coal ash detection is improved, ensuring that the detection value is closer to the laboratory test value.

Abstract

The invention discloses a coal dressing on-line ash content detection method and a detection sensing device, and relates to the technical field of ash content detection.The coal dressing on-line ash content detection device comprises a conveying table and a fixing frame, a natural ray ash content meter is installed on the inner side of the fixing frame, and the coal dressing on-line ash content detection device further comprises a feeding mechanism arranged on the conveying table and used for conveying coal to a to-be-detected part; the feeding mechanism comprises fixing shafts, the two sides of the conveying table are rotationally connected with two sets of fixing shafts correspondingly, connecting frames are fixed to the outer sides of the fixing shafts correspondingly, first movable frames are hinged to the outer sides of the connecting frames through circular shafts, and feeding hoppers are hinged to the top ends of the connecting frames; through cooperation between the vibrating screen and the groove, the vibrating screen is intermittently and slightly inclined towards the groove during vibration, so that the tiled coal particles are gradually conveyed towards the discharging frame, and the coal particles sliding off from the inner side of the discharging frame are distributed more uniformly, so that the coal ash content detection accuracy is improved.
