The present invention relates to an automatic dosing control system for papermaking. The system includes a control bus, a pasting pump, a pasting pump the main circuit, a pasting pump control circuit, a drug pump, a drug pump main circuit and a drug pump control circuit. The pasting pump main circuit, pasting pump control circuit, drug pump main circuit and drug pump control circuit are mounted on the control bus; the pasting pump main circuit is connected to the pasting pump; the drug pump main circuit is connected to the drug pump; the drug pump control circuit is provided with an automatic starting circuit; the automatic starting circuit and the pasting pump main circuit are in linkage control; and the pasting pump main circuit controls start or stop of the pasting pump through the pasting pump control circuit, so as to drive by the automatic starting circuit to control the drug pump control circuit to start or stop. Compared with the prior art, the invention has the advantages of easy operation, good security, and accurate dosing amount.
Description
technical field [0001] The invention relates to papermaking system control technology, in particular to an automatic dosing control system for papermaking. Background technique [0002] Different types of chemicals need to be added in the papermaking system to achieve different paper characteristics. The use effect of chemicals has high requirements on the accuracy of the amount added, the point of addition and the rationality of the way of addition. In general, the point of addition and the amount of addition are based on the characteristics of the chemical and paper. The way of addition affects the accuracy of the amount added and the uniformity of mixing of chemicals and slurry. The current addition methods are mainly divided into continuous addition and intermittent addition. The continuous addition method is easier to control, and the addition amount is also very stable. It is usually widely used. Part of the addition point is discontinuous slurry supply, adding chemi...
