The utility model discloses a
high silica glass fiber acid leaching treatment
bobbin, which is characterized in that a
chassis is arranged at one end of a
bobbin body, an
insertion port is arranged at the other end of the
bobbin body, a convex rib is arranged on the outer edge of one end of the bobbin body, which is positioned at the
insertion port, and through grooves are symmetrically arranged on two sides of the bobbin body; the base plate comprises an annular plate, an outer ring, an inner ring and a reinforcing plate, the annular plate is connected with the corresponding end of the
barrel, the outer ring is arranged on the periphery of the end, away from the
barrel, of the annular plate, the inner ring is further arranged at the end, away from the
barrel, of the annular plate, an annular clamping groove is formed in the inner wall of the inner ring in the circumferential direction, and the annular clamping groove is matched with the protruding ribs. High-silica
yarn can be directly wound through the
pipe barrel, the high-silica
yarn subjected to acid
pickling can have a long storage and
processing period, production plan adjustment and change are facilitated through semi-finished product storage, meanwhile, an acid
pickling coating agent is sprayed out from inside to outside through the through groove of the barrel body, so that pressure is applied to the high-silica
yarn, contact between the acid
pickling coating agent and the high-silica yarn is improved, and the service life of the high-silica yarn is prolonged. Therefore, the
acid treatment effect and efficiency are improved.
