Description
Technical field
The present invention relates to the aqua supply system that chemical industry pulvis is produced, relate in particular to the control device of aqua metered supply.
Background technology
In chemical industry pulvis production process, batching is one of crucial production link, will directly affect product quality and production cost.At present in pulvis production process, add aqua operation, be the liquid level gauge of being estimated monitoring aqua measuring tank by operating personnel, according to the liquid level condition of range estimation liquid level gauge, aqua pump and pipeline valve are opened in manual operations, in measuring tank, add liquid, or outwards emit liquid and transfer to pulvis production equipment.Because changing, liquid level in production process do not fix rule, larger by manual operation labour intensity, while reaching certain fatigue strength, even there is maloperation in operation often not in time, product quality is impacted, also there will be wastage of material phenomenon, increase cost, equipment can not be brought into play optimum efficiency, and production efficiency is difficult to improve.
Summary of the invention
Object of the present invention, just be to provide a kind of automatic control system of aqua metered supply, can auto-compensation and keep the amount of liquid in measuring tank, alleviate manually-operated labour intensity, conservation, raises the efficiency, performance functions of the equipments, with pulvis production equipment cooperation, guarantee that pulvis produces required aqua according to quantitative regular supply.
Task of the present invention completes like this: designing a kind of is the supporting aqua quantitative control system of powder production line, by control cabinet, liquid valve, drain pipe, measuring tank, supplying valve, feed pipe, large receiver, aqua pump mix proportion, the liquid level gauge nearside of measuring tank is provided with switch bracket, switch bracket is fixing on measuring tank, switch bracket epimere installing upper limit optoelectronic switch, hypomere installing lower limit optoelectronic switch are provided with separately photoelectricity indicator lamp on the wire line of upper limit optoelectronic switch, lower limit optoelectronic switch connection control cabinet.Liquid valve and supplying valve are Unidirectional solenoid valve, and the bottom surface of powder mixer is provided with travel switch, and travel switch is installed in the door unzipped positions that is positioned at powder mixer bottom surface, with door cooperating.Control cabinet is connected with upper limit optoelectronic switch, lower limit optoelectronic switch, liquid valve, supplying valve, travel switch respectively by wire.On control cabinet interior circuit board, install relay, breaker protector, the time relay, A.C. contactor; connect binding post with wire, be communicated with the wire of external power supply, upper limit optoelectronic switch, lower limit optoelectronic switch, aqua pump, supplying valve, liquid valve, travel switch, pneumatic on-off valve, mixer motor by binding post.In the time that the aqua liquid level in measuring tank reaches upper limit position, the upper limit optoelectronic switch outside liquid level gauge sends signal by wire to control cabinet, and by control cabinet, by the power-off of circuit control aqua pump, supplying valve is closed, and stops inputting aqua in measuring tank; When measuring tank discharges aqua, when in tank, liquid level drops to liquid level gauge lower position, feedback signal is reached control cabinet by lower limit optoelectronic switch, controlling the energising of aqua pump starts, supplying valve is open-minded, and large receiver is inputted aqua by feed pipe in measuring tank, until liquid level reaches liquid level gauge upper limit position; Now upper limit optoelectronic switch sends signal, and control cabinet is controlled the power-off of aqua pump again, supplying valve is closed, and large receiver stops to measuring tank input aqua.So cycle operation, guarantees that the aqua liquid level in measuring tank remains between the upper limit and lower limit, with powder mixer running beat cooperation, reaches best efficiency.
Manufacture experimently, test according to technique scheme, prove that the present invention is rational in infrastructure, matching performance is reliable, automaticity is high, effectively prevent that manual operation fatigue from causing maloperation, run well, can bring into play equipment best efficiency, guarantee the aqua supply in pulvis production process, reduce wastage of material and maintenance cost, reduce production costs, efficiency is high, profitable, reach preferably predeterminated target.
