Example Embodiment
[0015] The present invention will be further described in detail below with reference to the drawings and specific embodiments: see figure 1 , Example 1, a device for quickly calculating the amount of dye replenishment for dyeing residual liquid, including a filter 2, a cooler 3, a circulating pump 4, and a spectrophotometer 5 connected in sequence through a pipe 1. The pipe 1 is used for connecting end to end A weighing device 7 for weighing the mass of the dyeing residual liquid is provided at the bottom of the auxiliary tank 6 for storing the dyeing residual liquid. When the dyeing residue enters the attached tank, the circulating pump 4 drives the dyeing residue to flow in the pipe 1 and flows through the spectrophotometer 5. The spectrophotometer 5 can detect the absorbance of the dyeing residue under light waves of different wavelengths ,According to the concentration-absorbance working curve under the light wave of each wavelength, take the average value of several concen...
