The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model has been integrated the relation of disintegrating machine and two dynamical systems of charger, fully avoids causing because of the batcher charging is too fast the disintegrating machine overload operation, and then damages the generation of this phenomenon of crusher structure spare.In order to realize feed and broken effectively working in coordination with in the ore reduction process; make feed evenly, broken rapidly, produce continuously; the utility model improves on the basis of existing disintegrating machine and two dynamical systems of charger; set the carrying current value of former electrothermal relay RJ3 for protection disintegrating machine motor M 2; other increases overcurrent relay RJ2; the maximum current value of controlling disintegrating machine motor M 2 and producing, thereby the start-stop of control feeder motor M 1.
The utility model self-feeding control device of mineral crusher as shown in Figure 1 and Figure 2, comprising: batcher motor M 1 and disintegrating machine motor M 2 are connected with electrothermal relay RJ1, A.C. contactor KM1 on batcher motor M 1 main circuit; Be connected with electrothermal relay RJ3, A.C. contactor KM2 on disintegrating machine motor M 2 main circuits, be connected with A.C. contactor KM3, soft start RQ system on disintegrating machine motor M 2 control circuits, it is characterized in that: comprise the autofeed control circuit; In the autofeed control circuit, be connected with overcurrent relay RJ2 on disintegrating machine motor M 2 main circuits, batcher button 1SB1 is connected with overcurrent relay RJ2 normally-closed contact, the normally closed terminal of electrothermal relay RJI, batcher motor ac contactor coil KM1 by control line; When the electric current of disintegrating machine motor M 2 meets or exceeds the setting value of overcurrent relay RJ2, overcurrent relay RJ2 normally-closed contact disconnects, batcher motor coil KM1 dead electricity, batcher motor A.C. contactor KM1 main contact disconnects, and batcher motor M 1 quits work.
The utility model operation principle is as shown in Figure 2: before batcher button 1SB1 connects; be to light feed motor halt indicator HD3 by the normally closed terminal of KM1 before the ac contactor coil KM1 energising; be that feed motor halt indicator is bright, batcher is in stopped status.Connect when starting batcher button 1SB1, connect batcher motor ac contactor coil KM1 by control line 12,13,14, the normally closed terminal of overcurrent relay RJ2, electrothermal relay RJI, 1 work of batcher motor M is also lighted feeding machine motor indicator lamp HD2.
Press disintegrating machine start button 2SB1, power supply arrives the normally closed terminal 18 of A.C. contactor KM2 by the normally closed terminal 17 of 2SB2, makes the 1KA coil electricity control the coil electricity of A.C. contactor KM3, and the KM3 normally opened contact is lighted HD5 simultaneously, promptly soft beginning smooth start.Sending starting when soft start by setting-up time finishes, the inner K2 terminal of soft initiator closure makes relay K A normally opened contact KA closure, make A.C. contactor KM2 energising, A.C. contactor KM2 main contact closure, disintegrating machine motor M 2 operate as normal through control line 22,23.Through electrothermal relay RJ3 energising, finish the starting of disintegrating machine motor M 2, and pass through the normally opened contact of closed KM2, disintegrating machine run indicator HD4 is lighted, disintegrating machine brings into operation.
When disintegrating machine motor M 2 electric currents reached capacity, the normally-closed contact of electrothermal relay RJ3 disconnected, A.C. contactor KM2 outage, and disintegrating machine motor M 2 quits work, and finishes self-protection.
The utility model is set the carrying current value of electrothermal relay RJ3 for protection disintegrating machine motor M 2, and other increases overcurrent relay RJ2, controls disintegrating machine motor M 2 and the maximum current value of generation, thus the start-stop of control feeder motor M 1.Promptly when the electric current of disintegrating machine motor M 2 meets or exceeds the setting value of overcurrent relay RJ2, overcurrent relay RJ2 normally-closed contact disconnects, batcher motor coil KM1 dead electricity, A.C. contactor KM1 contact disconnects, be that batcher motor M 1 quits work, feeding suspends, and disintegrating machine motor M 2 still can be worked at this moment, thereby alleviates the live load of disintegrating machine motor.When disintegrating machine motor M 2 electric currents recover and are slightly less than the setting value of overcurrent relay RJ2, it is normal that overcurrent relay RJ2 normally-closed contact recovers, and promptly control line 13,14 is connected, and batcher motor KM1 is got, batcher motor M 1 turns round automatically, recovers normal feed.So repeatedly, saved operating cost greatly, the disintegrating machine motor has been carried out the most effective protection.Manpower and materials have been saved to greatest extent.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model.
