Abstract

The invention discloses an ore separation system and method based on microwave heating and infrared array imaging. The system comprises a vibration feeder, a conveying belt, a microwave heating device, an infrared array imaging detecting device and an ore separation device. The vibration feeder is used for conveying to-be-separated raw ore particles to the belt. The conveying belt is used for conveying the to-be-separated raw ore particles to the microwave heating device for performing microwave heating on the to-be-separated raw ore particles. The vibration feeder comprises a bin. The outlet at the lower end of the bin is located above one end of a chute. One end of the chute is mounted on a vibration motor. The discharge outlet at the other end of the chute corresponds to an optical detecting device. The infrared array imaging detecting device comprises an infrared array camera, a background radiation plate and an automatic dust removing device, wherein the infrared array camera receives the infrared radiation signals of the to-be-separated raw ore particles and transmits digital images acquired after A/D conversion to a computer for analyzing and processing through a data line. The ore separation device is a valve terminal connected with a gas source and used for separating the waste rock particles in the to-be-separated raw ore particles through blowing. The invention further discloses a method using the system.

Description

technical field [0001] The present invention relates to an ore sorting technology, in particular to an ore sorting system and method based on microwave heating and infrared array imaging, which is aimed at sorting raw ore particles (including ore particles and waste rock particles) with a particle size above 12mm , and divide it into ore particles and waste rock particles. Background technique [0002] At present, for the separation of raw ore particles with a particle size above 12mm, there are mainly two methods: wet separation and dry separation. The wet separation method is a kind of separation method that uses water, resuspension liquid or other liquid fluid as the separation medium. Wet separation has problems such as complex process, more equipment, large amount of water consumption, high environmental pollution, high investment and operation cost, and the application of wet separation method is also limited in areas with severe water shortage. Compared with wet sep...
