The invention provides a clarification device and method for a special glass conveying system. By means of the device and method, bubbles in the glass production process can be efficiently eliminated,and the flash points are reduced. A second heating control device heats a front segment heating area of a cylinder through a first electrode sheet and a third electrode sheet, and a third heating control device heats a rear segment heating area of the cylinder through the third electrode sheet and a fourth electrode sheet; multiple partition plates are perpendicular to the central axis of the cylinder separately and are arranged in the cylinder, protection gas through holes are formed in the upper portions of the partition plates, and molten glass through holes are formed in the lower portions of the partition plates; a protection gas pipe is arranged on the upper portion of the tail end of the cylinder, an exhaust pipe is arranged on the upper portion of the front end of the cylinder, and the first heating control device directly heats a heating section of the exhaust pipe through a second electrode sheet and the first electrode sheet. According to the clarification device and method, by adopting a segment direct-heating mode, through the partition plates, the phenomenon of flowing unevenness of molten glass can be effectively avoided. The quality of the product produced throughthe device and method is obviously improved, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the field of special glass manufacturing, in particular to a clarification device and method for a special glass production transmission system. Background technique [0002] Due to its special material properties, zero-expansion glass-ceramic not only requires high expansion consistency and optical uniformity of the glass, but also has extremely high requirements for the micron-level smooth quality of the glass working surface, and the bubbles and flash point in the glass will Tiny "pits" form on the working surface, affecting the performance of the imaging system. [0003] With the continuous development of liquid crystal display imaging technology, from the traditional high-definition display to the current mainstream 2K and 4K resolution display, the quality requirements for the TFT-LCD substrate glass used are becoming more and more stringent, and it is necessary to reduce the glass as much as possible. Quality defects su...
