Problems solved by technology

[0011] The above problems can be solved by increasing the length and number of platinum channel flow control loops, but this will increase the investment in the use of precious metals, electrical equipment, and plant construction, and the increase in the length of the platinum channel will also bring More platinum stone defects
Many production lines are upgraded on the basis of existing plant equipment, and the layout of the existing plant design also restricts the length and number of platinum channel flow control loops

Embodiment 1

[0061] use Figure 1 to Figure 4 In the platinum channel flow control system shown, the heating regulation loop includes 4 control loops (loop 1, loop 2, loop 3, and loop 4 from the left to the right of the drawing). The gas supplied by the heat-absorbing medium supply device 21 is a mixed gas of air and water vapor. The gas temperature is adjusted to 90°C and the humidity is 60%. The liquid flow rate is 400kg / h, and the thickness of the glass plate is 0.5mm. The sleeve inner wall 24a of the outlet sleeve 24 is 150mm away from the outer surface of the platinum channel. The air outlet 24c of the air outlet sleeve 24 is circular in shape, and the area of ​​each air outlet 24c is 76mm 2 .

Abstract

The present disclosure relates to a platinum channel flow control system, comprising a platinum channel (10), a heating regulation circuit for adjusting the flow of molten glass in the platinum channel, and an auxiliary adjustment of the flow of molten glass in the platinum channel (10) The cooling device (20). The flow control system provided by the present disclosure includes not only a traditional heating regulation circuit for regulating the flow of molten glass in the platinum channel, but also a cooling device for auxiliary adjustment of the flow of molten glass. That is, the temperature of the molten glass is lowered by the cooling device, so as to assist in adjusting the flow rate of the molten glass. In this way, the flow control system provided by the present disclosure can increase the electric heating power of the heating regulation circuit without increasing the number of heating regulation circuits and the channel length, thereby improving the ability of the heating regulation circuit to control the flow of glass liquid, so that The fluctuating range of the glass liquid flow is smaller, the product thickness difference and stress are smaller, and the product quality of the glass substrate is improved.

Description

technical field [0001] The present disclosure relates to the field of glass substrate manufacturing equipment, in particular, to a platinum channel flow control system. Background technique [0002] In the manufacturing process of TFT and LTPS glass substrates, the kiln process melts the batch materials into glass liquid and then reaches the platinum channel process for clarification and homogenization. After the glass liquid passes through the platinum channel process, it is sent to the molding process to be made into semi-finished glass plates After processing, it is made into a finished product, and then it can be sent to the panel manufacturer for use after packaging and transportation. [0003] With the panel display accuracy and the market's pursuit of ultra-thin products, panel manufacturers are getting higher and higher. In turn, the requirements for the thickness, thickness range and stress of glass plate products are higher, from the required thickness of 0.7mm, th...
