The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In accompanying drawing 5, HL1, HL2 are indicator lamp, and YB is buzzer, and ZS is rotating speed digital display meter, and SQ is approach switch.
The main design idea of employing of the present utility model 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 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.By sensor block, approach switch, revolution counter, can measure the revolution of driving drum and show.The tachometer value of revolution counter is lower than when setting value, and revolution counter makes the power-off of drive motors contactor to auxiliary reclay output signal.
Above-mentioned design philosophy is combined with concrete circuit, and the technical scheme obtaining is: the utility model comprises 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.On the driving drum end plate 11 of belt tramp iron separator, weld sensor block 6, 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.In switch board, place revolution counter ZS and be connected with approach switch 1, revolution counter ZS presets a fixing revolution value.By sensor block 6, approach switch 1, revolution counter ZS, can measure the revolution of driving drum 12 and show.When super large or overweight ironware are adsorbed on magnetic pole 13, the rotating speed of belt 10 sharply reduces maybe and cannot rotate, the rotating speed of driving drum 12 also sharply reduces and maybe cannot 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 power-off, and then drive motors power-off, buzzer siren YB reports to the police.
In the technical solution of the utility model, 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 utility model 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, transformer model is BK-300VA380V/220V, and transformer TC1 output AC 220V connects respectively that 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, KM1 coil obtains electric, and KM1 normally opened contact is closed, the self-insurance of KM1 coil, and meanwhile indicator lamp HL1 is bright; Button SB1, SB2 control respectively magnet exciting coil KM2 startup, stop, pressing SB1, 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.By approach switch SQ, sensed the rotating speed of belt, rotating speed digital display meter receives signal and shows the number of turns of belt running.
When belt does not turn round, KM1 normally opened contact disconnects, indicator lamp HL1 extinguishes, now rotating speed digital display meter ZS normally-closed contact disconnects, revolution counter stops counting, and revolution counter normally opened contact is closed, and buzzer siren YB reports to the police, alarm model AD16-22SM/23-AC.DC24V, is characterized in can sounding and following blinking light.
The utility model 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 utility model 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.
