Continuous circulation broken coal equipment of the present invention comprises the following steps when raw coal is carried out to fragmentation:
1. raw coal is inserted to the interior fragmentation of raw coal disintegrating machine 17;
2. the raw coal after fragmentation that raw coal disintegrating machine 17 discharging openings are discharged falls into the raw coal inlet 15 of open circles plate-like housing 4, enters the toroidal cavity 9 in housing 4, accumulates in the bottom of toroidal cavity 9;
3. the rotating disk 6 in housing 4 rotates under the driving of drive motors 10, drive material toggling framework 13 at the interior loopy moving of toroidal cavity 9 by shading ring 7, the former coal cinder that granularity in broken coal is more than or equal to 50mm by sieving net 14 on material toggling framework 13 is promoted to toroidal cavity 9 tops, when arriving toroidal cavity 9 top, the former coal cinder that granularity is more than or equal to 50mm discharges from rough coal outlet 16, the branch carrying in former coal cinder, the light weight sundries such as leaf polybag enter glove compartment 39 and are stored in glove compartment 39 from vacuum aspiration port 37 under the effect of negative-pressure air fan 38, open at discharge gate interval on toroidal cavity 9 bottom shell 4 sidewalls, the raw coal material that the granularity of toroidal cavity 9 interior storages is less than to 50mm is discharged,
4. the former coal cinder that the granularities that rough coal outlet 16 is discharged are more than or equal to 50mm slips into the charging aperture of raw coal disintegrating machine 17 along inclined ramp 18, again carry out fragmentation.
5. regularly open the cover plate 43 at 42 places, glove compartment 39 clean-up port, the foreign material in glove compartment 39 are cleared up.
The present invention is by the coal in raw coal, spoil and other foreign material are all crushed to three products heavy medium cyclone 3 can be below the particle diameter of sorting, carry out sorting by three products heavy medium cyclone again, raw coal circulation shattering process all completes voluntarily, it is again broken that the nonconforming coal cinder of particle size after cracking is sent raw coal disintegrating machine 17 automatically back to, whole process does not need man-handling of materials, can realize and enter continuously coal, produce coal continuously, labor cost and transporting equipment cost while significantly having reduced the coal washing operation of coal production enterprise, shorten the raw coal processing time, make coal washing step be easier to be accepted by coal production enterprise, the raw coal that is conducive to improve coal industry entirety enters to wash rate, raw coal at source can be targetedly to the coal product of selling different brackets with coal unit after sorting, be conducive to coal production optimization of enterprises product structure, improve the market competitiveness of product, increase the profit on sales of product, be adapted at applying on a large scale in coal industry, reduce the pollution level of coal-fired enterprise to environment, improve efficiency of fire coal, reduce transport power waste, in broken coal process, can sift out the most of light weight sundries carrying in raw coal, preventing that light weight sundries is blended in raw coal material in a large number causes the impurity content of final products too high.
Discharge gate of the present invention interval opens and closes, for realizing this function, preferred structure is: described discharge gate has flashboard 30, and the housing 4 at flashboard 30 one end and duff discharge gate 19 edges is hinged, flashboard seat 31 is installed on housing 4, and flashboard 30 is connected with flashboard seat 31 by hydraulic cylinder 32. This structure have open angle large, open and close and control advantage easily. Discharge gate of the present invention, except preferred structure, also can adopt other various structures, for example, can adopt rotating shaft to be arranged on the turning gate etc. at flashboard middle part, but these structure open angles are less, and open and close control comparatively loaded down with trivial details.
The angle of inclination of two circular side wall relative level faces of housing 4 of the present invention is preferably 45 °. Two circular side wall of housing 4 all relatively horizontal plane tilt 45 ° time, charging rate, the discharging speed of rough coal outlet 16 and the discharge velocity of duff discharge gate 19 of raw coal inlet 15 are the most balanced, two circular side wall of housing 4 are when all relatively the angle of inclination of horizontal plane is greater than 45 °, the discharge velocity of duff discharge gate 19 increases, but the discharging speed of the charging rate of raw coal inlet 15, rough coal outlet 16 can decline thereupon; Two circular side wall of housing 4 are when all relatively the angle of inclination of horizontal plane is less than 45 °, the charging rate of raw coal inlet 15, the discharging speed of rough coal outlet 16 increase, but the discharge velocity of duff discharge gate 19 can decline, in the time that the angle of inclination of two circular side wall relative level faces of housing 4 exceeds the scope of 30 °-60 °, the present invention there will be charging or discharge not smooth, easily blocks.
In figure, 33 is equipment supporters.
