Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, and particularly relates to an oil shale sorting device. Background Art

[0002] Oil shale is a sedimentary rock containing combustible organic matter. It can obtain shale oil, retorted gas and shale semi-coke through low-temperature retorting at about 500 °C. The method of making shale oil from oil shale is low-temperature retorting at 500 °C. However, if the content of inorganic minerals in oil shale is high, a large amount of energy will be consumed during heating, which will increase energy consumption and reduce efficiency. Moreover, the presence of a large amount of inorganic minerals is not conducive to the conversion of kerogen. Therefore, the oil shale for retorting needs to have an oil content of more than 5%, and the higher the better. The traditional methods for sorting oil shale include the heavy medium sorting method and the flotation sorting method. The traditional oil shale sorting methods have low recognition accuracy and it is difficult to effectively sort oil shale.

[0037] The working principle of an oil shale separation device provided by the present invention is as follows:

[0038] During use, the oil shale falls into the interior of the detection box 5 through the conveyor belt. By the rotation of the drive motor 13, the rotating plate 27 can be driven to rotate, and the detection box 5 storing the oil shale is rotated to the lower part of the detection plate 2. A detection signal is emitted by the ultrasonic transmitter 15 on the detection plate 2, and the transmitted signal is received by the ultrasonic receiver 7 to obtain the transmission time of the signal. The transmission time of the signal is sent to the corresponding processing device for calculation, and then the quality of the oil shale is obtained to achieve the separation of the oil shale.
