Embodiment Construction
[0031] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0032] In this disclosure, unless stated to the contrary, the used orientation words such as "upper" and "lower" are usually defined based on the direction in which the relevant parts are actually used. For example, the "lower" part of a steel channel refers to the When the groove is used, it is closest to the bottom of the ground; "inner" and "outer" refer to the contour of the corresponding component itself, for example, the "inner" part of a blind hole refers to the space surrounded by the forming surface of the blind hole; The "vertical direction" mentioned here refers to the direction perpendicular to the ground. For example, the "vertical direction" mov...

The invention relates to a launder device and a launder temperature control method. The launder device comprises a launder for molten glass to flow and a steel tank for mounting the launder, the launder device further comprises a heating part used for heating the molten glass, a temperature measuring part used for measuring the temperature of the launder, a control part used for controlling the heating part to work according to feedback information of the temperature measuring part and an upper enclosure used for forming a sealed heating space on the upper portion of the launder, and the heating part is arranged in the heating space and spaced from the molten glass; a plurality of blind holes which are concave inwards are formed in the outer side wall of the launder at intervals, the temperature measuring parts are arranged in the blind holes, the upper enclosure is arranged on the upper portion of the launder and connected with the two side walls of the launder in a sealed mode, and the upper enclosure and the launder are combined to form a heating space. During use, the control part controls the heating part according to the temperature of the launder measured by the temperature measuring part, and the temperature of the launder is adjusted by changing the heating power of the heating part, so that the temperature uniformity of molten glass is ensured, and the yield and the quality of glass are improved.
Description
technical field [0001] The disclosure relates to the field of glass processing and production, in particular, to a launder device and a method for controlling the temperature of the launder. Background technique [0002] Cover glass is mainly used in the outermost layer of the touch screen, also known as strengthened optical glass, glass window, strengthened mobile phone lens, etc. The main raw material of the product is ultra-thin flat glass. After cutting, CNC engraving, thinning, strengthening, coating, printing and other processes, it has the functions of impact resistance, scratch resistance, oil resistance, fingerprint resistance, and enhanced light transmittance. , the production of cover glass requires kiln to melt the batch materials at high temperature to form molten glass. Because the float process has the advantages of large capacity and good quality, the float process is preferred at home and abroad for glass melting operations. The high-quality molten glass en...
