Summary of the invention:
Technical problem to be solved in the utility model provides a kind of saving manpower, helps the coal powder supply device of environmental protection.
Above-mentioned purpose is achieved in that it comprises the coal bunker frame, on the coal bunker frame coal hopper is housed, near the last coal hopper quarrel grate is arranged, the hopper push-pull valve is arranged on the discharging opening of last coal hopper, near the discharging opening of last coal hopper feeds gig, gig one side has coal holding vessel supporting rack, coal holding vessel supporting rack is provided with the coal holding vessel, the discharging opening of coal holding vessel bottom has the holding vessel push-pull valve, on the supporting rack of coal holding vessel bottom discharge mouth below conveyor screw is housed, there is the temporary bucket of coal the below of conveyor screw discharge end, little turnover panel is contained in the top of the temporary bucket of coal discharging opening by axle, establish near switch near the temporary headwall of the coal the little turnover panel, the time relay in lead being arranged and be contained in control housing near switch is connected, and time relay has lead to be connected with the reductor of conveyor screw; The upper and lower of coal holding vessel is respectively equipped with level-sensing device and following level-sensing device, and the annunciator on upper and lower level-sensing device has lead respectively and is contained in the gig frame is connected with the annunciator in the control housing.
The utility model has the advantages that: can pour coal into coal hopper with loader, coal had both been saved manpower by this device automatic transport pulverized coal feeder, helped environmental protection again.
Description of drawings:
Accompanying drawing is that the utility model is contained in structural representation on the Coal-disintegrating machine 17.
The specific embodiment:
With reference to accompanying drawing, it comprises coal bunker frame 1, coal hopper 3 is housed on the coal bunker frame, near the last coal hopper quarrel grate 2 is arranged, hopper push-pull valve 5 is arranged on the discharging opening of last coal hopper, near the discharging opening of last coal hopper feeds gig 4, gig one side has coal holding vessel supporting rack 6, coal holding vessel supporting rack is provided with coal holding vessel 7, the discharging opening of coal holding vessel bottom has holding vessel push-pull valve 9, on the supporting rack 6 of coal holding vessel bottom discharge mouth below conveyor screw 10 is housed, there is the temporary bucket 11 of coal the below of conveyor screw discharge end, and little turnover panel 12 is contained in the top that coal is kept in the bucket discharging opening by axle, establishes near switch 13 near the temporary headwall of the coal the little turnover panel, time relay in lead being arranged and be contained in control housing near switch is connected, and time relay has lead to be connected with the reductor 14 of conveyor screw; The upper and lower of coal holding vessel is respectively equipped with level-sensing device 16 and following level-sensing device 15, and the annunciator 8 on upper and lower level-sensing device has lead respectively and is contained in the gig frame is connected with the annunciator in the control housing.Describedly all buy from market near switch, time relay, annunciator and push-pull valve.
Working process:
When installing and using, the discharging opening of the temporary bucket 11 of coal of the present utility model is placed the feeding mouth top of Coal-disintegrating machine 17, pour coal into coal hopper 3 with loader, coal dust enters hopper, coal cinder is separated by grate 2, gig 4 is imported coal holding vessel 7 with coal dust, and the coal dust reserves reach the upper limit of setting or are lower than the following of setting and prescribe a time limit in jar, and upper and lower level-sensing device starts alarm equipment alarm respectively; When depositing coal on the little turnover panel 12 in the temporary bucket of coal and reaching a certain amount of, little turnover panel can turn over coal automatically, this moment, little turnover panel left near switch 13, near reductor 14 outages of switch passage period relay control conveyor screw 10, after the coal dust on the little turnover panel turned over, little turnover panel automatically reset, contact near switch, after the time that reaches setting (as 2 minutes), time relay control conveyor screw reductor restores electricity, and conveyor screw works on.
