Technical Field
The utility model belongs to the technical field of spinning, and particularly relates to an acid bath device for stabilizing regenerated cellulose filament production.
Background
The concentration and temperature of sulfuric acid and zinc sulfate in the coagulation bath on the spinning machine are continuously reduced in the whole spinning process. To stabilize the spinning conditions we can continuously supply a constant composition and constant temperature acid bath to the spinning machine while flowing the diluted acid bath back to the acid station via a pipeline. In a sense, this constitutes the circulation of the acid bath. In the circulation system, the acid station sends acid bath meeting the technological requirements to a spinning machine bath tank, and viscose in the bath tank can be flushed out of a spinneret to carry out chemical reaction with sulfuric acid to generate fibers, wherein the concentration drop is generally in the range of 6g/L to 8 g/L. As the concentration and temperature of sulfuric acid and zinc sulfate in the coagulation bath decrease, the properties of the viscose fiber also fluctuate, which affects the quality of the fiber. The acid bath is indispensable in the regenerated cellulose filament production process, but the conventional acid bath balancing barrel still has the following defects in actual use:
In the existing practical production, the height of a traditional continuous spinning acid bath balancing barrel is 830mm, the diameter of the balancing barrel is 325mm, the highest flow rate of the acid bath per spindle position can reach about 35L/h when the balancing barrel keeps a certain liquid level, the flow rate can only meet the spinning condition that the spinning speed is not more than 160 m/min, and the production efficiency is relatively low; the conventional acid bath balance barrel is low in height, the flow velocity and flow rate of the acid bath in the glass tube under normal pressure are low, and the production requirement of high spinning speed cannot be met; the liquid level of the acid bath cannot be adjusted in a large range according to the process requirements of different varieties;
