Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of papermaking of the present invention is produced line pH value on-line measuring device and is applied to papermaking product lineUpper, can provide the system pH real time data of value to control system, system can baseCarry out technological adjustment pH value in these data, make system in optimum pH value scopeIn.
With reference to Fig. 1, pH value on-line measuring device of the present invention mainly comprises pH sensingDevice 1, pH transmitter 2, IO module 3 and middle control computer 4.
PH sensor 1 is for sampling detection, and its position need to be through scrutinizingChoose. The present invention is thinking pH sensor 1 after long term test, Datum ArgumentOptimum setting position is on white wate tray, and this position is without affecting sensor service lifeFactor, as steam, vibrations, deep-etching etc., be convenient to safeguard, get place, installation sideJust, do not impact producing, data feedback is sensitive, in time in reponse systemPH change, environmental drying herein, water flow impact pressure is little, shake little, dismounting sideJust, plain boiled water pH value can reflect system actual pH really herein.
After the position of pH sensor 1 chooses, need to be according to the spy of institute installation siteLevying property designs the shape of pH sensor 1. In the present invention, pH sensingDevice 1 comprises the metal of being located at the detecting head 5 of lower end and being fixedly connected with detecting head 5Cover 6, is welded with bolt 7 on detecting head 5, by bolt 7 and metallic sheath 6Lower end affixed, insert in white wate tray the lower end of pH sensor 1, pH sensor 1Fixedly be threaded onto on the end face of white wate tray by the fixing ear 8 of being located on metallic sheath 6.This structure can comprehensively be protected detecting head 5, metallic sheath 6 good airproof performances,1 integral installation of pH sensor is simple and convenient.
PH transmitter 2 is fixed on metope, and metope is in the upper position of pH transmitter 2The place of putting is provided with door 9, and the output line of pH sensor 1 is from metallic sheath 6 is drawn and pHTransmitter 2 connects. Door 9 can prevent transmitter laying dust ponding, can be to transmitterPlay certain protection left and right. PH transmitter 2 is by IO module 3 and middle control computer4 connect.
