Description

Technical Field

[0001] The utility model belongs to the technical field of meta-aramid production, and particularly relates to an automatic regulating device for a meta-aramid coagulation bath. Background Art

[0002] During the spinning and coagulation forming process of meta-aramid, a large amount of DMAC precipitates, resulting in a continuous increase in the concentration of the coagulation bath. During the meta-aramid spinning process, it is necessary to maintain a stable concentration of the coagulation bath to avoid large fluctuations in the concentration of the coagulation bath, which may lead to poor fiber forming and poor indexes. Therefore, it is necessary to accurately regulate the concentration of the coagulation bath during the spinning process.

[0003] However, there are some problems in the prior art: the existing automatic regulating device for the coagulation bath cannot automatically supply water. When people adjust the concentration of the coagulation bath, they need to manually supply water to the coagulation bath, which is laborious and time-consuming. Moreover, the manual water supply method is prone to large fluctuations in the concentration of the coagulation bath, and it is impossible to ensure the accurate control of the concentration of the coagulation bath. One-time water supply will cause the local concentration of the coagulation bath to be too low, and it takes a long time for the coagulation bath to become stable, which cannot meet the daily use requirements. Therefore, we propose an automatic regulating device for the concentration of the meta-aramid coagulation bath. Summary of the Utility Model

Moreover, one-time water supply will cause the local concentration of the coagulation bath to be too low, and it takes a long time for the coagulation bath to become stable, which cannot meet the daily use requirements.

When replenishing water, when the liquid level sensor 7 monitors that the water level in the water replenishing tank 6 is insufficient, at this time, the first solenoid valve 12 is opened, and the water inlet pipe 11 replenishes water to the water replenishing tank 6.

[0029] Through the setting of the mounting seat 81, it plays a role in preventing vibration during the use of the conveying pump 82, preventing the conveying pump 82 from being prone to jitter during use, and further causing problems such as loosening and falling off of the liquid suction pipe 83 and the liquid discharge pipe 84.
