Detailed description of the invention
In FIG, a representative embodiment of coal piece-rate system of the present invention is shown in signal.Described system is substantially with two stage work.
In the first stage, the coal 32 comprised in shell 10 is transferred to transporter 20.A conveyer belt 22 of coal 30 is settled above transporter 20 comprises, and the driver part 23 of mobile conveyer belt 22.The upper part of the starting end of the movement of transporter 20 is towards the gateway of shell 10, and below opposite tip tache motorice, container 70 can be used.Therefore, moving towards container 70 from the coal 32 that shell 10 overflows on conveyer belt 22 is placed in.On transporter 20, place optical system 40 to face conveyer belt 22.Optical system 40 comprises comprised camera 42.Camera 42 monitors the coal 32 on conveyer belt 22, and if wherein there is the object with a color except black, so by separation equipment 50 auxiliary under define a foreign body 34 and the separation from coal 30 be provided.Separation equipment 50 comprises the air blast illustrated in figure.Air blast in separation equipment 50 through placing so that at the terminal surface of conveyer belt 22 towards conveyer belt 22.It isolates the foreign body 34 that camera 42 is determined by being positioned by period in its front, to be undertaken moving from the projection-type of conveyer belt 22 by air blast.Reversion V-arrangement separator 60 is fixed on the end points place of conveyer belt 22.The foreign body 34 that separator 50 is discharged is collected in foreign body container 74 by breaking the barrier far away of reagent 60.Coal 30 reagent 60 closed-wall auxiliary under be directly collected in coal container 72.
In second stage, the coal 30 be collected in coal container 72 is placed in shell 10 to be separated based on quality.The transporter 20 with the structure similar with the first stage is still arranged in shell 10 front lower place.At the least significant end of transporter 20, container 70 still can be used at the bottom place of two walls facing separator 60 in the mode similar with the first stage.Container 70 has two containers, first quality coal vessel 76 and second quality coal vessel 78.On transporter 20, provide the x-ray equipment 80 facing conveyer belt 22.X-ray equipment 80 comprises x-ray generator 82 and receiver 84, and it is provided in below conveyer belt 22 to collect its ray passed through from coal 30.Receiver 84 is associated to provide signaling with microprocessor 86.
When the coal 30 that conveyer belt 22 carries by x-ray component 80 by time, it is illustrated as green by receiver 84 according to the ratio of contained organic component and is illustrated as redness according to inorganic component.Obtain color ratio under the help of microprocessor 86 and to process with green predetermined ratio according to red; The coal 30 being exposed to x-ray is defined as the first quality coal 36 or the second grade coal 38.Therefore, the first or second described grade coal 36,38 is sent to the first or second corresponding grade coal container 76,78 under the help of mechanical separator 90.In second stage, mechanical separator 90 comprises air blast.
Present system is a kind of device performing treatment step, the treating step comprises in the first stage, to purify coal 32 from foreign body 34; Subsequently in second stage, x-ray device 80 auxiliary under the coal set according to the scheduled volume of organic or inorganic material is identified as the first estate or the second grade coal 36,38, according to obtained definition, under the help of mechanical separator 90, be directed to corresponding container 76,78.Obviously, by determining a large amount of organic or inorganic quantity of material threshold value, coal 30 can be divided into two or more quality, and the second grade coal 38 determines more than one classifications.
