Description
Technical field
The utility model relates to dyeing automation field, particularly relates to a kind of dyeing course monitoring device.
Background technology
A chemical reaction process owing to dyestuff contaminating fiber, and need to carry out in pressure and elevated temperature vessel, so whole process can not be monitored when reality dyeing is produced, be all often that dyeing course terminates that rear logical hyperchromatic result is counter pushes through journey, accuracy and controllability do not ensure.How can real-time reflecting by the relation between the affecting parameters of dyeing course and correspondence thereof, replacing the judgement of Conventional wisdom by science data, is problem demanding prompt solution.
More existing on-line testing equipment are in the laboratory stage of fumbling mostly at present, and only for the single parameter in dyeing course, or do not carry out correspondence to multi-parameter and integrate, therefore cannot to bulk dyeing process carry out complete, objectively reflect.
Utility model content
Based on this, be necessary to provide a kind of can the dyeing course monitoring device of complete, objective reflection dyeing course.
A kind of dyeing course monitoring device, comprise data sink and be in turn connected to form the dye vat being provided with temperature sensor of loop, dye liquor cooling bay, data monitoring device and drawing liquid pump by pipeline, described temperature sensor and data monitoring device are wired or wireless is respectively connected to described data sink, wherein
Described data monitoring device comprise in the band spectrophotometer of flow cell, pH meter, conductivity measurement one or more.
Described temperature sensor can be arranged on any position that can contact with dye liquor in dye vat, for detecting the temperature of dye liquor in dyeing course.
Wherein in an embodiment, described data monitoring device comprises the spectrophotometer of the band flow cell connected successively by pipeline, pH meter and conductivity measurement, the spectrophotometer of described band flow cell is connected to described dye liquor cooling bay by pipeline, and described conductivity measurement is connected to described drawing liquid pump by pipeline.
Wherein in an embodiment, described flow cell is quartz glass flow cell.
Wherein in an embodiment, described dye liquor cooling bay arranged outside has water circulation pipe.
Wherein in an embodiment, described data sink is computer.
Principle of the present utility model is as follows:
Dyeing course monitoring device described in the utility model, by pipeline by dye vat, dye liquor cooling bay, data monitoring device and drawing liquid pump are in turn connected to form loop, after dyeing starts, drawing liquid pump constantly extracts dye liquor, make it at dye vat, circulate in dye liquor cooling bay and data detection device, data monitoring device can arrange the spectrophotometer of band flow cell as required, pH meter, one or more in conductivity measurement, to the absorbance of dye liquor, pH value, the data such as electrical conductivity are monitored, and by data upload to data sink, simultaneously, gather the temperature data of dye liquor in dye vat under the same time by temperature sensor in dye vat and be uploaded to data sink, in data sink, carry out correspondence according to acquisition time to each data integrate, objective technological parameter in dyeing course can be obtained, as dyestuff dye-uptake, the pH value of dye liquor, ion concentration etc.
The dye-uptake of dyestuff is calculated by dye liquor absorbance, and formula is as follows:
Note: the absorbance before initial dye concentration refers to and adds dyestuff; Real-time dye strength refers to the absorbance that each acquisition time is corresponding.
The object of test dye liquor intermediate ion concentration summation then can be reached by testing conductivity, thus the salt alkali concn played in monitoring dyeing, do foundation to technique adjustment (as water ratio, salt alkali concn), reduce because technological parameter (as water ratio, temperature etc.) change is on the impact of dyeing.
Compared with prior art, the utility model has following beneficial effect:
Dyeing course monitoring device described in the utility model, by the reasonable setting of each parts, complete in whole dyeing course, objective technological parameter can be obtained, for accurately judging that the dye combinations of dyeing and the reasonability of technique provide foundation fast, improvement dyeing more scientific thus, raising dyeing quality, have actual application value.
Accompanying drawing explanation
Fig. 1 is dyeing course monitoring device structural representation described in embodiment;
The process curve schematic diagram that Fig. 2 is dyeing course described in embodiment.
Detailed description of the invention
Below in conjunction with specific embodiment, dyeing course monitoring device of the present utility model is described in further detail.
