Operation principle:
Control unit controls five equipment such as Europe version flour mill main frame, blower fan, air door of fan, batcher, powder concentrator, discharge valve respectively, and system monitors blower fan electric current, main frame electric current, main frame vibrations, the parameter such as environment temperature near main frame simultaneously.Input parameter in touch-screen: 1. Europe version flour mill model (such as MTW175), 2. produces much grain products (such as 325 orders), 3. Choice and process product type (such as lime stone).The parameter that system inputs according to operating personnel, automatically the best debugging routine of engineer is loaded in program data base, press a key start button, system is started by sequence equipment, by the debugging routine of engineer by equipment debugging to optimum state, and according to the real-time corrected parameter of the debugging mentality of engineering, then ensure Europe version flour mill optimum state.
The debugging step of above-mentioned system is specific as follows:
1., after confirming that wiring is correct, switch on power, regulate each motor drive direction, make motor rotation direction consistent with design direction.
2. in picture, select material (such as lime stone); Machine entered model (such as 175).System according to machine models, the table look-up power and rated operational current that automatically calculate each motor.
3. press a key start button, system first starts discharge valve → startup powder concentrator → time delay 100S and starts blower fan → time delay 120S → startup main frame → startup electro-vibrating feeder.
4. automatically enter adjustment state.System start terminate after, automatically enter this state: a. system, according to the size of blower fan electric current, controls the size of air door, allow blower fan work load 90%.B. system is according to Main motor current, control batcher feeding coal, within first 30 minutes first, allow host work at 40% of load, 60%, 80% and check that main frame shakes, if main frame vibrations are in allowed band, after 30 minutes, automatic increase feeding coal, in the scope that vibrations allow, reaches load most until reach.After having debugged, again start, system directly enters optimal operational condition.
5., when system cloud gray model, system is by AI module testing environment temperature, and when environment temperature exceedes in the scope that equipment allows, according to temperature, regulate feeding coal, reduce machine burden, protection motor prevents Yin Wendu too high and damages.
6. system-down: user only needs by stop botton, and system reduces feeding coal gradually, when the electric current of mair motor drops to no-load current, system is shut down in order.System-down order is: electromagnetic shock batcher stopping → main frame stopping → time delay 60S → blower fan stopping → time delay 80S → powder concentrator stopping → discharge valve stops.
In the step 4 of above-mentioned debugging step, by selecting relation between feeding coal and main frame vibratory output to carry out the method for improving yield specifically, first main frame electric current is transferred to about 60% of load, check main frame shock momentum, if shock momentum is in allowed band, strengthen feeding coal, main frame electric current to 80%, detect vibrations, strengthen feeding coal, main frame electric current to 100%, detect shock momentum, if the vibrations system that exceeds standard reduces feeding coal, automatically to main frame electric current to 90%; If detect vibrations in allowed band, system increases feeding coal automatically.Until output, vibrations reach best.
From above-mentioned detailed description of the invention, expert control system for Europe version flour mill provided by the invention has rational in infrastructure, can automatically regulate batcher feeding coal, feed is constant, main frame current constant, grinding machine working stability is efficient, can see on-the-spot various parameters intuitively, and transfer and check relevant parameter in certain period, human-computer interaction interface is friendly, the advantage of simple operation.
