Abstract
The utility model relates to a machine for sorting gangue from fine coal, which sorts granulated primary coal by not using washing water and compressed air, but X-ray or isotope radial is used. The utility model is composed of a gangue backflow processing system, a multichannel granulated primary coal supply system, a sorting belt conveyer, an electronic pulse signal control system, a fine coal transportation electronic scale and a gangue discharging device. When the granulated primary coal or the granulated primary ore exported by the multichannel granulated primary coal supply system is transferred between the radiation source and a detector, the detector sends out signals, then the signals are transferred to the gangue discharging device by the electronic pulse signal control system, and the gangue discharging device attacks a connecting rod and excludes immediately the gangue in the primary coal and the impurity in the primary ore. The utility model has the advantages of small size, light weight, strong practicability, safety, reliability, low consumption rate and sorting cost, and high precision of distinguishing the gangue from the fine coal and sorting the impurity from the fine ore, and is an advanced apparatus for sorting gangue from fine coal at present.
Description
The utility model relates to the equipment of a kind of identification and sorting granule materials, and the cleaned coal in particularly a kind of sorting particle raw coal and the cleaned coal gangue sorting machine of spoil also can be used for the sorting of other granule materials.
From the fifties, the researcher of Britain utilizes Henry. and the X ray coal separation theory that professor Louis proposes developed " X ray sorting unit ", but, reasons such as power consumption many, easily wear out, poor stability big owing to the X-ray pipe volume is not used for reality.After, along with development of science and technology, the equipment research of sorting cleaned coal spoil has significant progress.But in time-delay control, discharge refuse control, many-sided defectiveness such as the recognition performance of bastard coal, and the interlock control apparatus of shortage safety and reliability.Therefore, poor safety performance, sharpness of separation is low, and sensitivity is low, and discharge refuse efficient is low, poor stability, operation inconvenience can't be satisfied requirement of actual application, can not drop into practicality.
The purpose of this utility model is to provide all very high safe and reliable, the good stability of a kind of accuracy of identification and sharpness of separation, practical cleaned coal spoil separating cleaner, and can be used for the sorting of other granule materials.
