Description

Automatic coal identification and separation material jacking device

Technical Field

The utility model relates to a train coal transportation technical field specifically is a coal automatic identification selects separately liftout device.

Background

The coal gangue is solid waste discharged in the coal mining process and the coal washing process, and is a black and gray rock which has lower carbon content and is harder than coal and is associated with a coal bed in the coal forming process. The coal quality of finished coal products is seriously affected due to low calorific value and more harmful substances, and the finished coal products need to be identified and sorted in time. To the less coal of granule and gangue, can adopt the medium to wash coal and the mode of selection by winnowing and remove impurity, to the great coal of granule and gangue, traditional processing mode is artifical the picking, along with the continuous development of science and technology, new letter sorting technique has appeared now, picks the gangue through X ray detection appearance and CCD camera matched with visual detection system promptly, and its process is: the coal is conveyed by a conveying belt, two hoppers are arranged at the tail end of the conveying belt, the coal and the coal gangue are distinguished by an X-ray detector, the position is determined by a CCD camera, a material beating device is composed of a plurality of high-pressure air nozzles which are uniformly distributed, after the position of the coal gangue is determined, a controller sends out a control signal after a period of time delay, an air valve is opened, so that the material deviates from an original track in the throwing process and falls into the gangue hoppers; if the coal is judged, the air valve does not act, and the material naturally falls into the coal hopper. However, in the actual use process, because the pressure of the high-pressure air nozzle is limited, if coal gangue with a larger volume is encountered, a good pushing effect is difficult to be achieved.

Therefore, an automatic coal identification, sorting and ejecting device is provided to solve the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a coal automatic identification selects separately liftout device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: an automatic coal identification and separation ejection device comprises a vibrating feeder, a conveying belt and a fixed table, wherein the vibrating feeder is positioned on one side of the conveying belt, the height of the vibrating feeder is higher than that of the conveying belt, the lower end of the vibrating feeder is provided with a screening device, the screening device comprises a fixed frame, a screen plate is arranged on the inner side of the fixed frame, one end, away from the conveying belt, of the screen plate is rotatably connected with the fixed frame through a rotating shaft, the tail part of the screen plate is provided with a convex block, the tail part of the screening device is provided with a supporting seat, the upper end of the supporting seat is provided with a motor, a cam for stirring the screen plate is arranged on an output shaft of the motor, one end, close to the fixed table, of the conveying belt is provided with an X-ray detector and a CCD (charge coupled device, and the computer is electrically connected with the X-ray detector and the CCD camera through leads.

This setting adds a screening plant in original coal sorting unit, can screen out the great granule of volume in the raw coal through screening plant, and the sieve can be continuous beating under the drive of motor and cam, because the sieve is to vibrating feeder's one side slope moreover, so large granule impurity and the coal cinder that the screening was come out can the landing downwards gradually to finally fall down from the bin outlet, because its quantity is less, only need carry out the manual work and select can.

Preferably, the fixed frame and the sieve plate are both inclined downwards at the end close to the vibrating feeder.

Preferably, be equipped with the square sieve mesh of a plurality of on the sieve, and the sieve is close to the one end of motor and is equipped with the bin outlet.

The large-particle object that this setting was screened can be followed the bin outlet and dropped, because coal cinder and gangue are anomalous mostly, compares square sieve mesh rather than the area of contact littleer with circular sieve mesh moreover, the difficult condition that takes place to block up.

Preferably, the upper end of the fixed table is provided with interfaces in one-to-one correspondence with the high-pressure nozzles, the interfaces are provided with electromagnetic valves, and the electromagnetic valves are electrically connected with a computer through leads.

The computer controls the electromagnetic valve to achieve the effect of controlling the opening and closing of the high-pressure nozzle.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses add a screening plant in original coal sorting unit, can screen out the great granule of volume in the raw coal through screening plant, the sieve can be continuous beating under the drive of motor and cam, moreover because the sieve is to vibrating feeder's a side slope, therefore large granule impurity and the coal cinder that the screening was come out can be the landing downwards gradually to finally fall down from the bin outlet, because its quantity is less, only need carry out the manual work and select can. Compare with traditional coal automatic identification selects separately liftout device, the utility model discloses can be better handle the large granule gangue, sort more accurately.
