The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
In accompanying drawing 5, HL1, HL2 are indicator lamp, and YB is buzzer, and ZS is the rotating speed digital display meter, and SQ is approach switch.
The main design idea of employing of the present invention is: on the driving drum end plate of belt tramp iron separator, weld sensor block, corresponding beam-end is placed an approach switch, and approach switch accesses to switch board medium speed table switching value contact 17,19,21 by the electric wire of 1 square millimeter, 3 core.Revolution counter is placed on the switch board panel, and it is FA8-RB10H that revolution counter is selected model, supply voltage 220VAC, indication range 0～9999, response speed 1S(second).Revolution counter presets a fixing revolution value.Can measure the revolution of driving drum and show by sensor block, approach switch, revolution counter.The tachometer value of revolution counter is lower than when setting value, and revolution counter makes the outage of drive motors contactor to the auxiliary reclay output signal.
Above-mentioned design philosophy is combined with concrete circuit, and the technical scheme obtained is: the present invention includes sensor block 6, approach switch 1, connecting plate 3, the first fixed head 2, the second fixed head 4, set bolt 5, revolution counter ZS.Welding sensor block 6 on the driving drum end plate 11 of belt tramp iron separator, corresponding crossbeam 9 ends are welded and fixed plate, by set bolt 5, the first fixed head 2, the second fixed head 4 and connecting plate 3 are fixed together, and approach switch 1 are arranged on connecting plate 3 simultaneously.Place revolution counter ZS in switch board and be connected with approach switch 1, revolution counter ZS presets a fixing revolution value.Can measure the revolution of driving drum 12 and show by sensor block 6, approach switch 1, revolution counter ZS.When super large or overweight ironware are adsorbed on magnetic pole 13, the rotating speed of belt 10 sharply reduces maybe and can't rotate, the rotating speed of driving drum 12 also sharply reduces and maybe can't rotate simultaneously, the tachometer value of revolution counter ZS is lower than setting value, the normally closed point of revolution counter ZS disconnects, make drive motors 14 contactor outages, and then the drive motors outage, buzzer siren YB reports to the police.
In technical scheme of the present invention, sensor block 6, approach switch 1, connecting plate 3, the first fixed head 2, the second fixed head 4, set bolt 5, be arranged on the end of belt tramp iron separator crossbeam 9 corresponding with driving drum 12, revolution counter ZS is arranged on its switch board panel.
Circuit loop of the present invention comprises major loop and control loop, major loop L1, L2, L3 three-phase alternating current 380V after circuit breaker Q F1 respectively through the normally opened contact of circuit breaker Q F2 A.C. contactor KM1 connect belt motor, again through circuit breaker Q F3 A.C. contactor KM2 normally opened contact and commutation system connecting coil.Control loop connects control transformer TC1 by three-phase alternating current 380V, the transformer model is BK-300VA380V/220V, and transformer TC1 output AC 220V connects respectively that the digital display revolution counter is often opened, normally-closed contact, KM1, KM2 normally opened contact, KM1, KM2 coil, buzzer siren and indicator lamp HL1, HL2.
In control loop, conventional push button SB4, SB3 control respectively belt motor startup, stop; Press button SB4, the KM1 coil obtains electric, KM1 normally opened contact closure, and the self-insurance of KM1 coil, meanwhile indicator lamp HL1 is bright; Button SB1, SB2 control respectively magnet exciting coil KM2 startup, stop, pressing SB1, the KM2 normally opened contact is closed, coil obtains electricly, indicator lamp HL2 is bright; TC1 output 220V alternating current connects digital display revolution counter ZS, then connects approach switch SQ by revolution counter.Sensed the rotating speed of belt by approach switch SQ, the rotating speed digital display meter receives signal and shows the number of turns of belt running.
When belt does not turn round, the KM1 normally opened contact disconnects, indicator lamp HL1 extinguishes, now rotating speed digital display meter ZS normally-closed contact disconnects, revolution counter stops counting, revolution counter normally opened contact closure, and buzzer siren YB reports to the police, alarm model AD16-22SM/23-AC.DC24V, be characterized in can sounding and following blinking light.
The present invention has thoroughly solved super large or overweight ironware is adsorbed on the magnetic pole of belt tramp iron separator, the problem that drive motors will locking burns then.Reduced and changed parking impact and the economic loss that motor brings.The present invention is simple in structure, reasonable in design, and drive motors is had to good defencive function, has replenished the blank of such device, is worth applying widely.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
