Platinum channel flow control system

Abstract

The invention relates to a platinum channel flow control system. The system comprises a platinum channel (10) for adjusting a heating adjustment return circuit of the glass liquid flow in the platinum channel, and a heat dissipation device (20) for assisting in adjusting the glass liquid flow in the platinum channel (10). The flow control system not only comprises the traditional heating adjustment return circuit for adjusting the glass liquid flow in the platinum channel, but also comprises the heat dissipation device to achieve auxiliary adjustment for the glass liquid flow, that is, glass liquid is cooled by the heat dissipation device, thereby achieving the auxiliary adjustment for the glass liquid flow. Thus, the flow control system can improve the electric heating power of the heating adjustment return circuit without increasing the number of the heating adjustment return circuits and the length of the channel, thereby improving the capacity of the heating adjustment return circuit to control the glass liquid flow, so that the fluctuation range of the glass liquid flow is smaller, the product thickness difference and stress are smaller, and the glass substrate product quality 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...

AI Technical Summary

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
