Described conveying belt dynamic scaling device 41 adopts LT-SS conveying belt velocity measuring device to be used as conveying belt detection of dynamic, and its principle of work is closed-loop control logic see what represent in Fig. 4, figure, and its main purpose is energy-conservation. Principle of work is: conveying belt once motion, will moving, the mechanical roller near displacement scaler on the conveyor belt produces to rotate, and this rotation can make the judgement that can open demagnetizer (anti-magnetized coil), by power controller controls output matching power supply, supply demagnetizer; As long as conveying belt non-stop run, the coupling power supply that power-supply controller of electric exports is also continually. If conveying belt stops, namely conveying belt displacement scaler is done to continue to wait, power-supply controller of electric stops power supply and exports, and thus reaches energy-conservation object.
It it is the control wiring scheme preventing conveying belt side partially excessive see Fig. 5, Fig. 5. Travel switch 39 in the demagnetization rack device of the present invention is in being connected in series, and is sent to Central Control Room after mutually connecting with the emergency stop switch 51 on existing transfer limes. Wherein: 52 is transfer limes emergency stop switch on multiple circuit, 53 for being sent to the line end (technique protection " tightly stops gathering " relaying loop) of Central Control Room.
The working process of the inclined conveying belt demagnetization rack device in the anti-side of suspension type of the present invention is: see Fig. 6:
Transfer limes starts rear �� conveying belt running �� conveying belt displacement scaler 41 and detects out conveying belt action �� power-supply controller of electric and power to demagnetizer 32; Conveying belt all can move by two avris to the left and right when normal operation, and scope is moved under the regulation and control of conveying belt unit and the effect of conveying belt rectification machine in this kind of side, can correct reset very soon, and left and right fluctuation can not be very big, common all within " permissible value " of skew. Within the scope of conveying belt normal excursions, the waist drum shape on the anti-magnetized coil frame of the demagnetization rack device of the present invention 33 4 angles by pulley 45,28 under the promotion of conveying belt to promoting �� anti-magnetized coil frame 33 overcomes and the magnetism of magnet steel moved adjustment �� automatically and offset continuation maintenance operation within " permissible value " at conveying belt in side to doing from gravity and four. When heavy rain arriving, mineral material Moisture high UCL, flyback conveying belt buildup, driving roll guide roller buildup, certain link generation fault of conveying belt unit etc. all can cause conveying belt side partially excessive. Conveying belt, once side is not partially excessively controlled, can cause conveying belt to fold, rub the substantial equipment accident such as on fire, also can damage conveying belt demagnetizer simultaneously, and this is exactly that conveying belt side is partially measured and exceeded caused by " ultimate value ". Super " ultimate value " afterwards conveying belt through waist drum shape by pulley 45,28 drive anti-magnetized coil frame 33 move to side �� anti-magnetized coil frame 33 overcome from the magnetism of gravity and magnet steel to do side move adjustment �� anti-magnetized coil frame 33 automatically continue partially �� anti-magnetized coil frame side inclined limit travel switch 39 laterally be triggered �� output switch amount signal (disconnect or close) �� transfer limes emergent stopping loop signal sends �� Central Control Room (technique protection " tightly stop set " relaying loop) if �� start immediately transfer limes all fronts shutdown �� Central Control Room send emergency maintenance instruction �� arrangement personnel's repairing �� fault remain unchanged �� the inclined limit travel switch in anti-magnetized coil frame side can continue to be triggered, and causes stall cycles. During if failture evacuation �� conveying belt resets back �� transfer limes restart �� enter normal circulation run.
The demagnetization rack device of the present invention has three kinds of states, see Fig. 7. When conveying belt normally runs, the anti-magnetized coil frame 33 of the present invention is suspended on conveying belt 23, allows conveying belt 23 navigate among anti-magnetized coil 32, see Fig. 7 a. When conveying belt offsets excessively to the left, the side of conveying belt 23 partially try hard to recommend dynamic under, anti-magnetized coil frame 33 overcome from gravity and four magnetism of magnet steel continued side inclined time, the inclined limit travel switch 39 in side is triggered by top, see Fig. 7 b. When conveying belt to right side shifted degree, when the side of conveying belt 23 partially try hard to recommend dynamic under, anti-magnetized coil frame 33 overcome from gravity and four magnetism of magnet steel continued side inclined time, the inclined limit travel switch 39 in side is triggered by top, see Fig. 7 c.
These are only the better embodiment of the present invention, be not intended to limit protection scope of the present invention, therefore, all do within the spirit and principles in the present invention any amendment, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
