Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and the raw material storage conveying control device of a kind of reasonable in design, management regulation, accurate measurement is provided.
Technical problem to be solved in the utility model is to realize by following technological scheme.The utility model is a kind of raw material storage conveying control device, be characterized in, it comprise control system, total storage tank and several minutes storage tank, be connected with feeding pipe on total storage tank, be connected by delivery line between total storage tank and the branch storage tank; Described control system comprises upper-position unit, PLC controlling center and several distributed Is/O module substation; On total storage tank, be provided with temperature transducer, pressure transmitter, steam regulation valve and magnetic upset level meter, on delivery line, be provided with flowmeter, transfer pump and electric switching valve, on feeding pipe, be provided with feedstock pump, be equipped with the electric control box of band secondary control loop on transfer pump and the feedstock pump, on minute storage tank, be provided with temperature transducer and magnetic upset level meter; Described temperature transducer, pressure transmitter, flowmeter, electric switching valve, electric control box, steam regulation valve and magnetic upset level meter all are connected with PLC controlling center or distributed I/O module substation by signaling line.
Technical problem to be solved in the utility model can also further realize by following technological scheme.Above-described raw material storage conveying control device is characterized in, total storage tank and 1 PLC controlling center control connection; Transfer pump, feedstock pump and 1 I/O module substation control connection; Each divides storage tank and 1-2 I/O module substation control connection.
The utility model preferably adopts S7-400PLC as controlling center, forms several substations with ET200 distributed I/O module, dispersed placement in each control room, place such as pump house, workshop storeroom; Adopt the RS-485 wiring between standing and standing, use PROFIBUS-DP field bus communication agreement to realize mutual communication, system equipment is managed concentratedly.Instrumentations such as temperature transducer, pressure transmitter, magnetic upset level meter, flowmeter can be monitored temperature, pressure, liquid level and feed flow in total storage tank, the branch storage tank, and various transducing signals are sent in the control station load module by shielded cable; According to coherent signal and on-the-spot needs equipment such as electric switching valve, feedstock pump, transfer pump are controlled, control signal sends to relevant device by dedicated signal lines.The upper-position unit operation interface can comprise functions such as real time monitoring, Print Form, real-time curve, historical trend, alarm logging, historical summary preservation, valve regulated, table page or leaf show, process parameter is provided with, easy-to-operat personnel and engineer's operation, and consult the related data data.
The utility model is provided with feedstock pump and transfer pump, is bearing transferring raw material to total storage tank and the responsibility that raw material is transported to the branch storage tank in the workshop from total storage tank.The utility model can be realized following monitoring requirement to feedstock pump and transfer pump: owing on the feedstock pump transferring raw material time a lot of uncertain factors are arranged, manually open/stop feedstock pump so in use often manually opened/stop feedstock pump as required or be chosen on the operation interface by existing operator.
The utility model mounting temperature sensor in total storage tank is mainly used in the temperature that monitors the raw material in total storage tank, and the temperature of being gathered shows on operation interface through handling.Setting pressure transmitter (preferably being contained in the top) is responsible for gathering the pressure in total storage tank on total storage tank, to guarantee micro positive pressure in total storage tank, regulates pressure by the direct-operated regulator of installing in tank base.For monitoring a jar interior liquid level, magnetic upset level meter has been installed on total storage tank simultaneously.Can set the liquid level upper and lower according to production requirement, when liquid level reaches lower limit in the storage tank, can report to the police automatically on the operation interface, must in total storage tank, replenish raw material as early as possible with this prompting operation person; When liquid level is higher than CLV ceiling limit value, report to the police, and on the warning interface, show, and the chain feedstock pump that stops.When lack of material in the workshop and automatic or manual when starting the raw material transfer pump can show fluid level condition automatically on the interface, give the correct time the chain transfer pump that stops when liquid level is low.
Flow measurement of the present utility model partly is by be provided with flowmeter, electric switching valve etc. on delivery line the raw material that enters the branch storage tank to be measured.Switch valve on the subtube is by the control of the branch storage tank supplied with, opens during low liquid level, and control system begins to add up simultaneously, throttle down during high liquid level, and the flux cumulating number enters total metering of this minute storage tank.Divide storage tank to replenish raw material in order successively, control system is metered into corresponding minute storage tank successively.
