Automatic separator of coal gangue

Abstract

The invention relates to an automatic separator of coal gangue, which comprises a raw material feeding copper, a coal receiving copper, a gangue receiving copper, a conveying-belt conveyor, an identification and separation controlling mechanism and an executing mechanism, wherein the conveying-belt conveyer is arranged among the raw material feeding copper, the coal receiving copper and the gangue receiving copper; the identification and separation controlling mechanism comprises a single-energy gamma ray source, an X-ray sensor, a measure and control instrument and an ultrasonic transmitter-receiver; the single-energy gamma ray source is arranged below a conveying belt, the X-ray sensor is arranged above the conveying belt and corresponds to the single-energy gamma ray source, the measure and control instrument is electrically connected with the X-ray sensor, and the ultrasonic transmitter-receiver is arranged above the conveying belt and electrically connected with the measure and control instrument; the executing mechanism is a high-frequency air valve arranged above the coal receiving copper and the gangue receiving copper; and the valve port of the high-frequency air valve is arranged towards a throwing track of coal and gangue. As the single-energy gamma ray source is adopted, only one nuclear radiation material exists, and only one spectral line is radiated, the mutualinterference among a plurality of spectral lines can not be generated; and the invention has accurate measurement and good separation effect.

Description

technical field

[0001] The invention relates to an automatic sorting machine for coal gangue. Background technique

[0002] The existing coal gangue automatic sorting machine, as disclosed in Patent No. 2005200313106, includes a raw material feeding hopper, a coal receiving hopper, a gangue receiving hopper, and a conveyor belt arranged between the raw material feeding hopper and the coal and gangue receiving hoppers. The conveyor, the identification and sorting control mechanism and the actuator, the identification and sorting control mechanism includes a dual-energy gamma ray source arranged below the conveyor belt, a ray sensor located above the conveyor belt corresponding to the position of the dual-energy gamma ray source, and The measurement and control instrument electrically connected to the ray sensor and the ultrasonic transmitter receiver electrically connected to the measurement and control instrument are arranged above the conveyor belt between the ray sensor an...
