• Figure-1 is a schematic illustration of an alternate embodiment of the separation system of the inventive dry coal representative.
• FIG 1 one representative embodiment of the coal separation system of the invention is schematically shown.
• the system is basically works in a two-stage.
• tuvenane coal (32) contained in the casing ( 1 0) is being transmitted to a conveyor (20).
• Conveyor (20) comprises one band (22) on which coal (30) is laid and a drive member (23) that moves the band (22).
• the upper part of the starting end of movement of the conveyor (20) faces the mouth of the casing (10) and under opposite the tip motion end the containers (70) are available.
• tuvenane coal (32) spilled from the casing (10) lading on the band (22) starts to move towards a container (70).
• an optical system (40) is placed so as to face the tape (22).
• Optical system (40) includes a camera (42) included.
• Separation apparatus (50) comprises a blower illustrated in the figure.
• the blower in the separation apparatus (50) is placed so as to face the band (22) at the end of the band (22). It estranges the foreign body (34) determined by the camera (42) by targeting it during the passage in front of it so as to make a projective motion from the tape (22) by blowing air.
• An inverted V shaped a separator (60) is fixed at the endpoint of the band (22).
• Foreign bodies (34) expelled by the separation device (50) are collected in a foreign body container (74) by breaking the far barrier of reagent (60).
• Coal (30) is directly collected in a coal container (72) with the aid of the closed wall of the reagent
• coal (30) collected in the coal container (72). is placed in the casing (10) to separate basing on the quality.
• a conveyor (20) with a similar structure to that of the first stage is still is arranged at the bottom in front of the casing (10).
• container (70) is still available at the bottom which is facing the two wall of the separator (60) in a manner similar to the first stage.
• Container (70) has two vessel for one of the first quality coal vessel (76) and one second quality coal vessel (78).
• X-ray apparatus (80) facing to the tape (22) is provided on the conveyor (20)
• X-ray apparatus (80) comprises an x-ray generator (82) and receiver (84) provided below the band (22) so as to collect its rays passing from coal (30).
• the receiver (84) is associated with the a microprocessor (86) so as to provide signalling.
• the coal (30) carried on the band (22) is passed by x-ray means (80), it is illustrated green according to the proportion of organic components contained in and according to inorganic components in red by the receiver (84). Obtained colour ratio is processed with the help of the microprocessor (86) and according to the predetermined proportion of red and green colour; the coal exposed to x-ray (30) is defined as the first quality coal (36) or second grade coal (38). Accordingly, the described first or second grade coal (36, 38) is sent to corresponding first or second grade coal container (76, 78) with the help of a mechanical separator (90). In the second stage the mechanical separator (90) includes a blower.
• the inventive system means a device that performs processing steps consisting in the first stage, the purification of tuvenane coal (32) from foreign bodies (34); subsequently in the second stage, the identification of the coal which is set according to the predetermined amount of organic or inorganic material with the aid of x-ray device (80) as a first grade or the second grade coal (36, 38), according to the obtained definition, orientation to the corresponding container (76, 78) with the help of a mechanical separator (90). It is obvious that by determining a large number of the amount of organic or inorganic material threshold, the coal (30) can be divided into more than two qualities and second grade coal (38) determines more than one class.
