The invention relates to a pollution-free production technology of direct fast black G, comprising the following implementation steps: firstly, primary acid coupling is carried out on nitroaniline after diazotization and H-acid; after the full reaction of the H-acid is detected, sodium carbonate is added and pH is adjusted to 8 to 8.2 to carry out secondary basic coupling; the coupling product isadded into a sodium sulfide solution for reduction, and the temperature gradually raises to t of 38 DEG C to 40 DEG C in the reaction process; after the sodium carbonate is added into the reduction product after acidification to adjust the pH of a medium to 7.5 to 8, the mixture is adsorbed by activated carbon and filtered, and ternary coupling is carried out on the obtained filter liquor after diazotization and lentine; and after the reaction is detected to be end point, the materials are directly delivered to a drying tower for spray drying. In the invention, the reduced reaction solution does not need the processes of salting out, acidification and filtration, activated carbon adsorption is adopted instead. In the process, no waste liquor is generated, and environment pollution caused in the production process of dye is greatly reduced. Simultaneously, wastewater processing is not needed, and the cost is saved. The optimized technology directly transfers the reaction solution afterternary coupling into the drying tower for spray drying; and the yield and the coloring intensity of the dye are effectively increased, energy is saved, the consumption is reduced, and the effect is obvious.

CV carton transparent paper packaging machine automatic cigarette filling method and the device used
ActiveCN104085555BReduce labor intensityReduce manufacturing costPackaging cigarettePackaging automatic controlProcess engineeringPaper sheet
The invention relates to an automatic cigarette strip supplement method and device for a CV strip box transparent paper packaging machine. The method mainly comprises the steps that cigarette strips are sequentially placed in from a cigarette strip supplement component, and two synchronous belts on the cigarette strip supplement device drive the cigarette strips on the synchronous belts to be conveyed to a cigarette strip transverse conveying component and a cigarette strip lifting component for transparent paper packaging. The automatic cigarette strip supplement device mainly comprises a transmission gear box, the cigarette strip supplement component, the cigarette strip transverse conveying component, the cigarette strip lifting component and the like. The automatic cigarette strip supplement method and device have the advantages that automatic strip supplement is achieved on the condition that the CV strip box transparent paper packaging machine works independently, the labor intensity of operators is reduced, a large number of raw and auxiliary materials are saved, and the production cost of the cigarette industry is reduced.
