Abstract
The invention discloses a movable-electronic weighing automatic filling system for an orthophthalic unsaturated winding resin. The device comprises a 25-ton orthophthalic winding resin automatic control principle, which comprises six sub-systems, namely an automatic liquid material delivery system, an automatic control system for a material temperature rise stage in a reaction kettle, an automatic control system for a material esterification stage in the reaction kettle, an automatic control system for negative pressure reaction in the reaction kettle, an automatic control system for a material transfer stage and an automatic control system for crosslinking dilution in a dilution kettle. Advanced equipment is combined, and an automatic control system for an unsaturated resin production process flow is formed. The system is mainly used for improving automation level, stabilizing product performance, improving production efficiency and reducing work load in the production process.
Description
Technical field
The technology of the present invention has designed a kind of principle, and specifically 25 tonnes of adjacent benzene types twine production of resins Auto-control of the process principle.Be mainly used in improving in process of production automatization level, stable prod performance, the load of enhancing productivity, lighten one's labor.
Background technology
Along with the development of advanced composite material industry, China increases year by year to the demand of unsaturated polyester resin.At present at home, the enterprise of part collective, small towns production resin emerges in a large number.But because they self production technology is relatively weaker, the vibrin product performance of production are very unstable, and this has also affected the quality of product.This has also reflected unsaturated polyester resin production technique-dissolve method intermittence, technical maturity, but manual operations, and quality is unstable, and human factor causes error.Secondly DCS system every profession and trade extensive successful Application of chemical field only at home, and domestic and international sensor technology is also very ripe.
Summary of the invention
The present invention refers to that specifically 25 tonnes of adjacent benzene types twine the resin Automatic Control Theory, comprise the automatic delivery system of liquid material; Reactor material temperature rise period automatic control system; Reactor material Esterification Stage automatic control system; Reactor negative reaction automatic control system; Turn material stage automatic control system; The 6 large subsystems such as the crosslinked dilution automatic control system of dilution still form.In conjunction with sophisticated equipment, form the automatically system of control of a kind of unsaturated polyester technological process of production.
Description of drawings
Fig. 1 is overall craft process principle figure of the present invention
Embodiment
Referring to Fig. 1, described sequence number explanation is followed successively by: 1. be the DCS Master Control Room; 2. be that liquid material is delivered operating device automatically; 3. be reactor material temperature rise period automatic control system; 4. be reactor material Esterification Stage automatic control system; 5. be reactor negative reaction automatic control system; 6. be to turn material stage automatic control system; 7. be the crosslinked dilution automatic control system of dilution still; 8. be reactor; 9. be the dilution still; A is feedback signal; B is control signal.Before the beginning, Central Control Room is injected into reaction mass in the reactor by DCS control liquid delivery system by feedback signal, when various materials reach the design proportioning, is transmitted control signal by DCS, and topworks interrupts feeding intake.Then the logical automatic control that heats up rises to suitable temp with temperature of reaction kettle and keeps, and the Esterification Stage automatic control system is started working, and after solution parameter in the still is up to standard, carries out negative reaction and automatically controls.After product in the still is qualified, turn material stage automatic control system and start working, solution in the reactor is extracted out and is injected in the dilution still.In this stage, the crosslinked dilution automatic control system of dilution still is started working, with the dilution of the product in the still and cooling, for follow-up can is prepared.
